Claims; (o1. z71-2.1s
Thepresent invention relates to a magazine for an elon gated record medium. 1
flhe'magazineofthepresent invention is capable of folding and holding in a storage chamber a substantial length of anfelongated record medium, which may he a tape ofi the type commonly used-in magnetic recorderlfeproducer apparatus. Theinvention has for its primary obiect the provision of a new and improved magazine of this character and also the provision of a new and improved reproducerapparatus with which the magazine is associated.
A further object of the present invention is to provide a new and improved magazine for holding lengths of elongated record medium which is simple and inexpensive to construct, which may be readily attached. to and detached from associated apparatus such asareproducer, and which is constructed with record medium guiding means adapted. cooperatively to be associated with record medium driving, and guidingmeans forming part of the apparatus.
, Ahfurther object the present invention is to provide a new and i-mproved' apparatus for reproducing from an elongated record medium, which apparatus has associated with it arriagazine adapted dtachably to be placed on the .front'of the apparatus, the apparatus beingsocongprovide anew and improved record mediumanagazine so mmune-m1 and arranged that the medium can be entirely ehclosedwithin the magazine whereby the latter "can be Il a-11521351166 bl mailedwithout likelihood of injury to The medium which can be shipped: in the magazine. This safety feature can also be utilized during standby periods when the recorder reproducer apparatus is not being used or is being. moved from one location to another.
In brief, the present invention comprises structure defining 'a-st'orage chamber for an elongated record medium, which str'uctureincludes spaced apart front and back walls anditpper andlower sides and-including entrance and exit openings providing for the ingress and egress of the record medium, which maybe magnetic tape of the type common-ly-used with magnetic recorder-reproducer apparatus. The-magazineis especially intended to hold and store, so to speak, a substantial length of an endless tape which is utilized as for announcement purposes. The tape enters the chamber through an enlarged inlet opening and leaves the chamber through an exit opening. The discharge .isefiected through felt pads engaging the tapesoas to pre- Viitli10l'b'tlili1 a single strand or ribbon "of the tape from being d S s P n dischargedandto maintain the 't'a'pe'under tension.
f ice The tape is automatically folded inside the chamber so tliat a substantial .quantityof tape. is loosely held inthe a transducer and tape guiding and driving means forming part of the apparatus. The magazine is mounted in: front of the apparatus clear of obstructions sothatmagazines of different depths may be utilized, even magazines extending below the bottom of the apparatus proper. The magazine may also be constructed with the entrance and exit openings in close proximity, as at the top of the magazine, to the associated recorder-reproducer apparatus so, as to reduce to a minimumv the length. of medium exposed in use. Also, the portion of the magazine between the entrance'and exit openings may be openable to enable the medium totally to be enclosed in the magazine, for shipmerit, etc.

, -netic tape 12, upon which a suitable messagerisrecorded.
The reproduoer includes tape d-ni-ving means and reproducing means to be described later and :a novel magazine indicated as a whole by reference character 14, which is detachably secured to thefiront wall i the reproducer.
:In orderto provide a better understanding of the nature and advantages :of the present invention, it might he stated that the reproducer :h'ereuillustrated is intended for use in making periodic announcements or making such an nouncements. in response to automatic control function occurring as upon the opening of a doo1'-or cover or the like. Gr, the apparatus might be' placed into continuous operation upon depression of a control button 18 at the front of the reproducer 10, which button constitutes an -apparatus start and run buttom However, the starting and stopping 'of the reproducer can be effected "automatically as hereinbefore mentioned, Under automatic operation the "-reproducer is started as by the opening of a door or a 'c'overandit operatessunt'ilthe tape, which maybe an endless tape, completes a cycle of movement, whereupon the alongfthe lines 3-3 and al -dot reproducer is deenergized and placed in temporary nonoperative condition.
The tape 12, upon which a suitable message is recorded, is driven by a rotatable constant speed capstan having an annular groove adapted fairly snugly to receive the tape. The tape is held against the capstan by a pinch roller 22 mounted on a pivotally movable arm 24 biased toward the capstan as by a spring 27.
The tape driving means is located in advance of a suitable transducer 26 mounted upon the front wall16 of the reproducer and including a housing 28 having a longitudinal opening 30 enabling the tape to come into close proximity with the magnetic core of an electro-magnetic I pickup device which may be of the type disclosed and claimed in my co-pending application Serial No. 79,663, filed March 4, 1949, and assigned to the assignee of this application now abandoned but superseded by application Serial No. 408,235, filed February 14, 1954.
The tape is guided past the transducer and capstan by a pair of idler rollers 32 and 34 in advance of the transducer and capstan, respectively, and in alignment therewith. The tape is held against the transducer and idler roller 32 by suitable biasing means such as the spring arms 36 and 38 secured ,to a bracket 40 pivotally mounted on the front wall 16 of the reproducer. as the felt pads 42 and 44, may be placed at the ends of the arms for engagement with the tape.
The magazine 14 of the present invention includes a tape storage chamber comprising a back wall 52, and
a front wall 54 spaced therefrom a. distance readily to receive the tape, see Fig. 3. It includes also a top wall 56, preferably constituted by an integral forwardly extending flange of the back wall and provided with a relatively long entrance opening 58 through which the tape enters the storage chamber. The ingress of the tape into the chamber is facilitated by flaring the opening somewhat and by associating with it guiding means 60. The flaring Suitable pads, such iseasily provided by an upwardly and rearwardly inclined flange 62 on the back wall and upwardly and forwardly inclined flange 640m the front wall 54, which flange can extend the full length of that wall. The guiding means comprise a generally U-shaped structure, the bight of which is secured to the front wall and from the legs of which there extend the opposed arms 66 and 68 terminating near the capstan. 1
The magazine includes also a bottom wall 7 0 and end walls 72 and 74, constituted as by integral rearwardly extending flanges of the front wall. The bottom wall is provided with a-tape exit opening 76 Within which are mounted a pair of felt pads 78 adapted to engage opposite sides of the tape, see Fig. 2, thereby to prevent more than I a single thickness of the tape from being discharged and to maintain the tape under tension. The pads may be mounted upon a flanged supporting bracket 80, the vertical back of which is secured to the rear of the back wall 52 a and the horizontal spaced flanges of which extend through the back wall to receive the pads so that the pads are located substantially in the exit opening 76.
In accordance with another feature of the invention the front and back walls of the magazine are detachably supported and secured to each other by meansenabling ready attachment and detachment. For this purpose the rear wall is provided with resilient fastening clips 82, only one of which is shown in Fig. 3, and the front wall with a ball-ended rearwardly extending fastening post 84. This construction enables the ready initial placing of the tape in the magazine as well as substitution of one tape for another.
The magazine as a whole itself is portable and is also adapted detachably to be secured to the front panel 16 of the reproducer by fastening means enabling ready attachment and detachment. The fastening means may be identical with that already described and include a spring clip 86 and a ball-ended fastening post 88, the former being mounted on the front panel 16 and the latter on the rear wall 52. It is preferred that three of the latter fastening means be used, there being one at each of the upper corners and one at the center lower part of the back wall.
The use and operation is' also facilitated, in accordance with the present invention, by providing tape guiding means on the magazine. The guiding means may take the form of idler rollers 90 and 92, both of which may be, as illustrated, secured to the back wall and the former of which .is located below the tape exit openingand the latterin alignment with the guide roller 32 mounted upo the front panel in advance of the pickup head.
The tape may be protected in use by a cover having a perforated top and front wall 93 and side walls 94 of which but one has been shown andwith a substantially open bottom wall defining a slot 96. The bottom wall is made open so that magazines having heights difierent from that illustrated may be placed on the apparatus so that longer tape lengths may be used. In this connection it should be noted that the present magazine and reproducer are so constructed and arranged that magazines of various heights may be used without any different mode of installation or operation.
Assuming that a magazine has been placed on the reproducer and the tape threaded past the guiding and driving means and the transducer, and the reproducer placed in operation as by depression of the start button 18, the tape is moved past the transducer by the cooperative action of the capstan and pinch roller. The signals previously placed on the tape are now reproduced periodically as complete lengths of the tape pass by thetransducer. A considerable length of tape may be stored in the magazine chamber which it enters through the inlet opening 58 and wherein it is folded in a somewhat haphazard fashion as illustrated in Fig. 2. It leaves the magazine at a rate determined by the drive and past the pads 78 which maintain the tape under tension.
When it is desired to change the message being reproduced, the magazine can be removed along with the tape and another magazine with a tape having a different message can be substituted, or, if desired, the front wall of the magazine alone may be removed for substitution of a new tape. I
Referring now to Fig. 5, there is illustrated a modified magazine constructed and arranged to reduce the length of tape exposed between the magazineand associated apparatus, thereby minimizing the likelihood of damage to the tape. The magazine is also characterized by a construction enabling the tape entirely to be enclosed in the magazine so that the magazine can be used as a shipping or storage container or as a holding device for the tape when the apparatus is moved from place to place with the magazine on it.
The magazineis indicated in Fig. 5 by the reference character 100. It includes a tape storage chamber 102 defined by a back wall 104 and a front wall 106 spaced therefrom, the back and front walls corresponding generally to the walls 52 and 54 of the previously described embodiment. The magazine also includes a top wall comprising a first portion 108 constituted as by an integral forwardly extending flange on the back wall and a sec-- ond portion 110 which is openable either by removal or hinged movement relative to the magazine, the latter type of construction being illustrated and the hinges being indicated by the reference characters 112. -If desired the hinged portion can be held in closed position as by suitable latching or spring type biasing means. These two portions are separated sufiicicntly to provide the magazine with a. relatively long entrance opening 114 having associated with it the flare providing flange 116.
The magazine includes also a bottom wall 118 and spaced end walls, of which only the end wall 120 is shown. The upper end of the latter is spaced a short distance from the top wall portion 110, thereby to provide a tape exit opening 122 from which the tape emerges p from the magazine. 7 V a transverse slot 130 through which the tape moves, this slot being in line with the opening between the pads and of tape that is exposed during use of the apparatus.
upwardly in line with the tape guiding roller 32 shown in Fig. 1.
The tape is guidedthrough the exit opening by tape guiding means taking the form of a pin 124 which can be secured to the back wall of the magazine. 1 This pin is located substantially in line with the guiding roller 32 and the exit opening 122 so that the tape freely moves out of the magazine.
The tape is maintained taut and more than a single strand or loop is prevented from being pulled out of the magazine by the tape engaging felt pads 126 secured forward, in so far as tape movement is concerned, of the guiding means 124. The .pads are mounted upon a suitable support, which may take the form ofa vertically extending element 128 defining, in efiect, a partition preventing the tape loops in the magazine from getting tangled with and interfering with the discharge of the tape 12 The support 128 is provided with the guide pin 124. It should be noted also that the support-partition 128 extends approximately to the bottom of the magazine and divides the storage chamber into what may be called a main storage chamber and an exit chamber.
Referring to Fig. 6, there is illustrated a slight modification of the magazine of Fig. 5 with the corresponding parts designated by the same reference numerals. In this case the vertically extending element 128' is provided with a horizontal extension 134 having the transverse slot 130 defined therein through which the tape 12 leaves the magazine, this exit opening being at the bottom of the magazine, The same pads 126, and guiding means 124 would still be employed. The support 128' again divides the magazine into a main storage chamber and an exit chamber with the tape exit opening at the bottom.
It will be apparent to those skilled in the art from the foregoing detailed description of the invention that the location of the entrance and exit openings at or near the top wall of the magazine places these openings very close to the associated recorder-reproducer apparatus, thereby minimizing and reducing to a minimum the lezlgth spaced upwardly from said bottom flange, ;means in Having thus described my invention, what I desire to claim as new and desire to secure by Letters Patent of the United States is:
1. A portable storage magazine for holding an elongated length of record medium and adapted to be detachably mounted on a supporting member comprising a first wall member, a second wall member having flanges on the sides and bottom edge thereof, means for detachably mounting said second wall member on said first wall member to define a cavity for receiving said record medium, partition means positioned within said cavity adjacent one of said flanges and extending from the top toward the bottom of said cavity to define an exit passageway, said partition means having an opening therein tegral with said first wall and extending outwardly therefrom toward said second wall to partially close said cavity, and means movably mounted on said first wall and spaced from both said integral portion and from one of said side flanges to define an entrance opening and an exit opening in alignment with said passageway.
2. The storage magazine set forth in claim 1 in which the partition means includes means spaced from and extending parallel to the bottom flange of the second wall member to define an extension of said exit passageway in communication with said cavity.
