AUTOMATIC CASSETTE CHANGING AND PLAYING APPARATUS This invention relates to automatic cassette changing and playing apparatus. More particularly, the invention is concerned with an apparatus for automatically changing and playing a plurality of cassettes successively each of which contain therein a magnetically recorded tape or movie film.

In one apparatus known in the art of automatic playing of cassettes, a plurality of cassettes are piled in a stack in a cassette case and the lowermost cassette is first played. After completion of playing, the lowermost cassette is moved downwardly and removed from the apparatus, and the cassette now in the lowermost position is then played and moved downwardly after completion of playing. This process is repeated until all the cassettes in the case are played.

This apparatus has disadvantages. The cassette being played cannot be observed under direct vision. Difficulty is experienced in taking out a cassette because it is moved downwardly after being played.

A general object of this invention is to provide a novel automatic cassette changing and playing apparatus which obviates the aforementioned disadvantages of the prior art apparatus.

A main object of the invention is to provide an apparatus which permits to automatically change and play a plurality of cassettes one after another.

Another object of the invention is to provide an automatic cassette changing and playing apparatus which permits to readily observe a cassette under direct vision while it is being played.

Another object of the invention is to provide an automatic cassette changing and playing apparatus in which a cassette taken out of a number of cassettes stored in a predetermined position is played in a playing position and moved to a predetermined position after completion of playing. The apparatus is effective to automatically detect the completion of playing of one cassette and perform a next operation.

Another objectof the invention is to provide an automatic cassette changing and playing apparatus which comprises means for taking out a cassette from a first cassette case in which cassettes yet to be played are housed and moving it to apredetermined playing position, and means for moving. a cassette from the playing position into a second cassette case after completion of playing of the cassette in the playing position.

Another object of the invention is to provide an automatic cassette changing and playingapparatus in which cassettes are successively piled in a stack in superposed relation in a cassette case after completion of playing.

Still another objectof the invention is to provide an automatic cassette changing and playing apparatus which comprises means for automatically detecting the position of the trailing. end. of a magnetic tape in the cassette by sensing an increase in the tension of the tape when playing reaches an end.

A further object of the invention is to provide an automatic cassette changing: and playing apparatus which is rendered inoperative when all the cassettes housed in a cassette case have been played.

Additional objects as well as-features and advantages of this invention will become evident from the description set forth hereinafter when considered in conjunction with the accompanying drawings, in which:

FIG. 1 is a plan view of a first embodiment of the automatic cassette changing and playing apparatus according to this invention;

FIG. 2 is a front view of the apparatus of FIG. 1;

FIGS. 3 to 5 are perspective views, on an enlarged scale, of a mechanism for starting and stopping essential portions of the apparatus of FIG. 1;

FIGS. 6 and 7 are perspective views, on an enlarged scale, of a mechanism for starting and stopping the control gear section;

FIGS. 8 and 9 are plan views of the means shown in FIGS. 6 and 7 respectively;

FIG. 10 is a front view of the cassette conveyor means;

FIG. 11 is a perspective view of the cassette case;

FIG. I2 is a perspective view of the control gear;

FIG. 13 is a perspective view of "the cassette horizontal conveyor means;

FIG. 14 is a side view of the means shown in FIG. 13;

FIGS. 15 and 16 are perspective views of the means for actuating the head support plate;

FIGS. 17 to 19 are front views of the cassette pushdown means;

FIGS. 20 to 22 are side views of the cassette push-up means;

FIG. 23 is perspective view of the automaticstop means;

FIGS. 24 to 27 are views in explanation, on an enlarged scale, of the essential portions of the means shown in FIG. 23; and 7 FIG. 28 graphically shows the operation of various members in relation to the rotational angles of the control gear.

The present invention will be explained with reference to an embodiment which uses. cassettescontaining magnet tapes available in the market.

In FIGS. 1 and 2 which are a plan view and a front view respectively of the apparatus in its entirety, a cassette case 12 is mounted on a chassis base 10 by four support posts l3, l3.

The cassette case 12 comprises a housing for containing cassettes yet to be played (A), a playing station (B) and a housing for containing cassettes already played (C). The two housings (A) and (C) are of box-shape and have a bottom for placing thereon cassettes yet to be played and cassettes already played respectively. Formed in a side wall and a bottom wall of the housing (A) are an opening 12a and a slit 12b respectively which act as a path of travel of a cassette feed movable plate 56 subsequently to be described.

Mounted on the outer surfaces of the front and rear walls of the housing for containing cassettes already played (C) are four claws 67, 67 each of which is formed of a plate spring and includes an obliquely upwardly directed forward end portion 67a extending through a window 12c into the interior of the housing (C). The claws 67, 67 are each fixed to the front and rear walls in a position such that the forward end portion 67a is disposed at a level slightly higher than that of a cassette as measured from the bottom of the housing (C).

Provided in the playing section (B) is a movable plate 52 which can move up and down as guided by support posts 13, 13. Openings 52a and 52b are formed in the movable plate 52 for cassette reel driving spindles to extend therethrough. The movable plate 52 is normally urged upwardly by the biasing forces of springs 102,
