DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] With reference to FIG. 1, there is shown an assembly generally indicated at 10 of a portable printer generally indicated at 11 and a portable data entry device generally indicated at 12. The printer 11 and the device 12, individually, as well as the assembly 10 are portable and in particular are hand-held for ease of use. The device 12 includes a scanner 13 at its front end for scanning a bar-coded label L. The device 12 also has manually operable keys 14 and a display 15. The scanner 13, the keys 14 and the display 15 are housed in an elongate relatively thin housing 16. Manually depressing buttons 14′ operates the scanner 13.

[0028] The printer 11 is shown to have an elongate housing 17 having opposed mirror-image housing sections 18 and 19. The front portion of the housing 17 has a compartment or space or pocket 20 for receiving and releasably holding the data entry device 12. The compartment 20 has an open top 21 to enable the keys to be operated and to enable the display 15 to be seen. The compartment 20 is channel-shaped as diagrammatically depicted in FIG. 6 to capture the data entry device 12. As shown, the housing 17 has flanges 22 and 23 which help retain the device 12 captive in the compartment 20. The front end of the compartment 20 is open as indicated at 24 to enable the device 12 to be slid into the compartment 20. The device 12 is releasably latched in the compartment 20 by opposed latches 25. The latches 25 are each comprised of a pad 26 flexibly secured to a wall 27. The pads 26 have opposed projections 28 which are received in recesses 29 in the housing 16 of the device 12. By simultaneously depressing both pads 26 rearwardly of the wall 27, the projections 28 are withdrawn from the recesses 29 which allows the device 12 to be slid out of the compartment 20.

[0029] The underside of the device 12 has a 10-pin connector 30 which cooperates with a mating 10-pin connector 31 on the housing 17. As the device 12 is slid into the compartment 20 in the direction of arrow A in FIG. 2, the connector 30 at the rear end of the device 12 connects with the connector 31 at the rear end of the compartment 20, thereby enabling the data entry device 12 to control the printer 11. The latches 25 are latched when the connectors 30 and 31 are connected.

[0030] As is apparent from FIG. 3, the underside of the printer housing 17 has a hollow or concave surface 32 for receiving the palm of the user's hand. A strap 33 can fit about the back of the user's hand. The strap 33 can be a continuous loop of a hand as shown in FIG. 3. FIG. 3 also shows the device 12 diagrammatically and that a label roll R and a prior art print module or print mechanism generally indicated at 34 are disposed at a rear portion of the printer 11. The label roll R is illustrated as being comprised of a label web (or a web of labels) W received in space 35 in the housing 17. The roll R is suitably supported either at its central opening 36 or simply in a cradle 37 as shown. The web W passes from the roll R between a thermal print head 38 and a platen roll 39. The printed label web W exits the housing 17 at a slot 40 one side of which is formed by a tear edge 41.

[0031]FIG. 7 shows that the print module 34 comprises a frame 42 which has sockets 43 and 44. The module 34 includes a platen roll 45 having a shaft 46. The shaft 46 is releasably held in the sockets 43 and 44 in the FIG. 3 position. The module 34 further includes an electric motor 47 and gearing generally indicated at 48. The gearing 48 includes gear 49 on the shaft 46. Springs 50 which bear against a support 51 resiliently mount the print head 38.

[0032] The platen roll 45 is rotatably mounted to a cover 52. In particular, the shaft 46 passes through a flange 53 and is removably received in a C-shaped cutout 54 in a flange 55. The end of the cover 52 opposite the platen 45 has a pair of outwardly extending projections 56 for receipt in opposed recesses 57 in the housing sections 18 and 19. Accordingly, the cover 52 is pivotally mounted for movement between a closed or operating position shown in FIGS. 1 and 3 and an open or non-operating position as illustrated in FIG. 2. It is apparent when the cover 52 is in the position shown in FIG. 2, a label roll R can be readily inserted into the space 35. If the roll R has a core C as shown the core can be readily removed. Also, the print head 38 and the platen roll 39 can be readily cleaned when the cover is in the open position. If required, the platen roll 45, its shaft 46 and its gear 49 can be readily replaced by snapping the portion of the shaft 46 between the flanges 55 and the gear 49 out of the socket 44, and pulling the other end of the shaft 46 out of the hole in the flange 53.

[0033] As best shown in FIG. 4, the print module 34 and upstanding battery contacts 58 are mounted on a printed circuit board 59. The connector 31 is connected to the printed circuit board 59 via conductors 31′. A ribbon connector 60 connects the print head module 34, particularly the motor 47, the print head 38 and sensors (not shown) to the printed circuit board via a connector 61. There are four contacts 58 on each side of the printed circuit board 59 for releasable contact to four rechargeable batteries 62. The connector 31 which is mounted to a support 63 is connected to the printed circuit board 59. A port 64 accessible from outside the housing 17 is connected to the printed circuit board 59. The batteries 62 are held in a holder generally indicated at 64 which holds the batteries 62 in position but keep the batteries 62 from touching each other. The holder 64 maintains the batteries 62 aligned with opposed pairs of contacts 58. The holder 64 surrounds the outsides of all the batteries 62 as best shown in FIG. 4. The holder 64 has fin-like separators 65 joined to a peripheral wall 66 and to a bottom wall 67 (FIG. 3) The bottom wall 67 is connected to the printed circuit board 59 by integrally molded pins 68. The holder 64 is particularly beneficial in the event the assembly 10 or the printer 11 is dropped or otherwise impacted.

[0034] The printed circuit board 59 is captive between the housing sections 18 and 19 in transverse slots 69 and 70. The support 63 is received in slots 71 and 72. The housing sections 18 and 19 are connected by screws (not shown) received in aligned holes 74.

[0035] Floor 75 of the compartment 20 is provided with an access opening 76 which is closed off by a cover 77. The door 77 is pivotally mounted about a hinge axis 78 for movement between the closed position shown in FIG. 2 and an open position to provide access for loading and removing the batteries 24. The cover 77 is releasably held in the closed position by a releasable latch 78′.

[0036] The printer 11 is compact, by way of example not limitation, one embodiment of the printer 11 has a length of about 8.31 inches (211 mm), a height 2.38 inches (60 mm), a width of 3.38 inches (86 mm) and a weight of 0.9 pound (0.4 kg.); and the data entry device 12 has a length of 5.46 inches (140 mm), a height of 0.66 inch (17 mm), a width of 3.16 inches (81 mm), and a weight of 6.1 ounces (0.17 kg).

[0037] With reference to FIG. 8, there is shown the portable data entry device 12 and a printer 80. The printer 80 has an elongate housing 81 having a lower housing section 82 and an upper housing portion 83. An adapter or adjuster 84 is connected to the upper housing section 83 by a plurality of threaded fasteners 85. The adapter 84 together with upper surface 86 of the housing section 82 forms a compartment 87 for receiving the data entry device 12 in piggyback fashion as shown in FIGS. 12 and 15.

[0038]FIGS. 8, 9 and 10 show a set of three different adapters 84, 84′ and 84″ and a set of three corresponding different data entry devices 12, 12′ and 12″. Thus, the adapter 84 is shaped to fit or accommodate the data entry device 12, the adapter 84′ is shaped to fit or accommodate the data entry device 12′, and the adapter 84″ is shaped to fit or accommodate the data entry device 12″. As shown the data entry device 12′ is narrower than the data entry device 12 and the data entry device 12″ is thicker than the data entry devices 12 and 12′. It is thus apparent that the printer 81 can be readily modified or adjusted to accommodate different data entry devices.

[0039] The adapters 84, 84′ and 84″ are all shown to have a generally U-shaped configuration and are each preferably of one-piece molded construction. The adapter 84 has vertically extending wall sections 88 and 89 and a wall section 90. The wall sections 89 and 90 are parallel and the wall sections 88 are generally parallel to each other. Opposed faces of the wall sections 88 have frictional or gripper members 91 which grip the housing 16 of the data entry device 12. The housing 16 of the device 12 also has a lip or gripper 16′ which cooperates with a ridge 93′ on the adapter 84 to help releasably hold the device 12 to the printer 80. Alternatively, or in addition, it is preferred that the adapter 84 be comprised of an elastomeric material which will enable the data entry device to be yieldably held in the docked position in the compartment 87. Thus, the data entry device 12 is frictionally held in the compartment 87 by the gripper members 91 and 93′. The wall sections 88 and 90 are integrally joined to a horizontally extending U-shaped retaining flange 92. The compartment 87 is provided by the wall sections 88 and 90, the flange 92 and the upper surface 86 of the upper housing section 83. End edge portion 93 is sculptured or tailored to the data entry device 12 so that keys 14 can be operated while the data entry device 84 is docked in the compartment 87. The top portion of the adapter 84 is open, in the same way as the compartment 20 is open to enable the display 15 to be seen.

[0040] The data entry device 12′ is narrower than the data entry device 12 and thus the distance between walls 88′ is less than the distance between the walls 88 so as to fit or accommodate the data entry device 12′ between wall sections 88′.

[0041] The data entry device 12″ has a different arrangement of buttons 14″ than the data entry devices 12 and 12′ and as such the horizontal flange 9″ is sculptured or tailored to allow access to the buttons 14″.

[0042] In other respects the adapters 84′ and 84″ are identical to the adapter 84. As seen in FIGS. 8, 13 and 14, a coupling C in the form of a connector generally 94 is secured by screws 95 to the top or flange 92. The wall section 90 has a stepped opening 96 (FIG. 14). The connector 94 has a vertical collar 97 and a horizontal bar 98. The wall 90 is positioned between the collar 97 and the bar 98 to help hold the connector 94 in position on the adapter 84. The connector 94 is also positioned against an upstanding projection 99 on the upper housing section 83. The front upper portion of the connector 94 has a plurality of contacts 100 for contacting mating contacts on the data entry device 12.

[0043] As seen in FIG. 12 for example, the printer 80 and the data entry device 12 are used in the same manner as in the embodiment of FIGS. 1 through 7. The data entry device 12 is disposed at a front portion of the printer housing 81. A printer module 101 and space S defined by a surface 81′ for mounting a label supply roll R are disposed at the rear portion of the housing 81 and a magnetic card reader generally 102 is disposed between the data entry device receiving compartment 87 and the print head module 101 with its print head 101′. So, therefore, data can be printed by the printer 80 from data received from the data entry device 12, from the card reader 102 or through data ports 103 or 104 (FIG. 13).

[0044] The data ports 103 and 104 are mounted on a U-shaped printed circuit board 105. The printed circuit board 105 is electrically connected to a printed circuit board 106. Conductor 107 is shown to connect the connector 94 to the printed circuit board 106. The print head module 101 and the card reader 102 are mounted on and are electrically connected to the printed circuit board 106.

[0045] As shown in FIG. 13, the housing section 81 has a pair of longitudinally extending horizontal lands 108 which support side margins of the printed circuit board 106. The lands 108 are joined to a pair of parallel, vertical, opposed walls 109. The printed circuit board 105 is secured to a rigid post 110 by a screw 111 between the walls 109. The lands 108 have holes 112 through which screws 85 pass into the adapter 84. In this way the adapter 84 is held securely to the lower housing section 82 and to the upper housing section 83.

[0046] The upper housing section has an inclined portion 113 with a door 114 pivotally mounted on spaced arms 113′ by two studs 115 received in opposed holes 116. The door 114 rotatably mounts a platen roller 117 which cooperates with the print head 101′ as shown in FIG. 15. The door 114 has a flexible handle 118 for assisting the user in opening the door 114.

[0047] The card reader 101 is used to read a magnetic card MC. The adapter 84 and the adjacent wall 113″ of the inclined portion 113 are spaced to provide a slot S′ so that the magnetic card MC can pass therethrough between members 119 and 120. The card reader 101 has a pair of U-shaped members 119 and 120. The member 119 is positioned at opening 121 in the adapter 84. The other member 120 is positioned at an opening 121′ of the inclined portion 113 (FIG. 15). When the print head module 101 prints, the printed labels L issue through an opening 122 in the inclined portion 113.

[0048] As best shown in FIG. 13, a pair of manually engageable members 123 and 124 are secured to the outside surfaces of walls 109. The members 123 and 124 are identical except that the member 123 has a differently shaped rectangular plug 125 from rectangular plug 126 of the member 124. The plug 125 fits into a hole 127 and the plug 126 fits into a hole 127. The members 123 and 124 are each of one-piece molded, resilient, elastomeric construction. Each member 123 and 124 has inner surfaces with three identical undercut projections 128. The projections 128 fit through holes 129 in the walls 109 and are captured at the undercut 130 as best shown in FIG. 16. The inside surfaces of the members 123 and 124 from which the projections 128 extend also have a raised or convex portion 131. Each convex portion 131 is aligned with a switch 132. If either switch 132 is depressed the scanner 13 will be operated to read the bar code on the label L. Convex portions 133 on the outside surfaces of each of the members 123 and 124 are aligned with the convex portions 131 and are depressible by the user to operate the switches 132. The plugs 125 and 126 are preferably positioned in respective openings 127 and 127′ when the ports 103 and 104 are not in use. However, by flexing the members 123 and/or 124 to their phantom line positions shown at PL in FIG. 13, the respective ports 103 and 104 can be uncovered for use.

[0049] The lower housing section has a compartment 134 for receiving a battery 135 connected to the printed circuit board for powering the printer and its electronics. A door 136 closes the compartment 134.

[0050] By way of example, not limitation, the print head module 101 can be a Fujitsu FTP 638MCL100 print head module and the card reader 110 can be a Semek 4083-0 card reader.

[0051] Other embodiments and modifications of the invention will suggest themselves to those skilled in the art, and all such of these as come within the spirit of this invention are included within its scope as best defined by the appended claims.
