The present invention relates to an electronic apparatus and more particularly, but not exclusively, to a customer serviceable data processing terminal.
Background Art
Serviceability by customers is an important consideration in the design of certain data processing terminals. Such serviceability is enhanced by providing ready access to the interior of the terminal where the electronic components are normally located.

Accordingly, the present invention provides an electronic apparatus including a housing and a keyboard module, characterized in that said keyboard module is releasably mounted on said housing in a position whereby removal of said keyboard module from said housing provides access to the interior of sa'd housing for servicing electronic components therein and further characterized by cooperating electrical connector means on said keyboard module and said housing to provide electrical coupling between said keyboard module and said elsctrical components within said housing, said electrical connector means forming part of electrical circuit means for interrupting the power supply to said electronic components whenever said keyboard module is removed from said housing.

Best Mode for Carrying Out the Invention
Referring now to Figs. 1A and IB, a terminal housing 20 includes a body 22, a top 24 and a side piece 26 which is removable and replaceable to permit some alterations in the terminal housings to meet differing customer needs with respect to certain components such as magnetic stripe readers. Assembly of the elements 22, 24 and 26 leaves a large aperture at the upper front of the terminal 20, through which access may be had to the interior of the terminal 20 for purposes of maintenance and repair. This aperture is closed when the terminal is in use by a keyboard 28, shown in exploded form in Fig. 1A. The keyboard 28 includes a keyboard module 30, a key caption sheet 32, a transparent overlay 34 and a bezel 36 which frames and retains the sheet 32 and overlay 34 of the keyboard 28.
The keyboard module 30 contains a plurality of touch-activated switch pads 40 arranged in a suitable keyboard configuration. Depression of the switch pads 4.1 causes switch closure or other appropriate means for the generation of electronic signals which are transmitted through an electrical connector 42 which operatively engages with a mating connector 44 connected to other electrical components within the terminal 20 when the keyboard 28 is assembled to the remainder of the terminal exterior structure.
Included in the circuitry extending through the connectors 42, 44 is the power supply circuit generally designated as 46 shown in Fig. 4. The ground connection 48 for this circuit is located in the keyboard 28. Said circuit extends through the connectors 42, 44. The circuit also includes an NPN transistor 50, the base of which is connected through a resistor 52 to a control conductor 54. The emitter of the transistor 50 is connected through a resistor 56 to a +5-volt regulated source of potential 58, and to the ground connection 48. The collector of the transistor 50 is connected through a resistor 60 to a +5-volt regulated source of potential 62, and is also connected via a conductor 64 through a connector 66 to a power supply (not shown) for the terminal 20. It will be seen that operation of the power supply can be controlled by the operator or by other terminal functions by means of a signal of proper level on the conductor 54. It will further be seen that when the keyboard 28 is removed from the terminal 20, the ground connection through the connectors 42, 44 is broken, and the signal level on the collector of the transistor 50 remains at a high +5-volt level, so that the power supply remains turned off.
Returning to the keyboard module 30, this is provided on the bottom with a matrix of reinforcing -"" bars 70 and 72 at right angles to each other, to improve the rigidity of the module 30. The connector 42 is fixed within a support 74 which is fixed to the horizontal base 77 of the module 30, and to several of the bars 72.
At its upper end, adjacent the connector 42, the module 30 is provided with three tabs or projections 76 which engage complementary slots 78 when the keyboard 28 is assembled with the rest of the terminal 20.
Along each side, the module 30 is provided with two cut-away portions 79. In each portion 79 is provided a projection 80 which extends across part of the bottom opening of the portion 79. The portions 79 and projections 80 coact with inwardly extending tabs 82 molded integrally with the housing 22 on one side of the terminal 20, and with inwardly extending tabs 84 molded integrally with the side piece 26 on the other side of the terminal 20 to assist in retaining the keyboard 28 in position in the terminal 20. In addition, the upper ends 86 of internal ribs 88 engage the bottom of the keyboard module 30 at the edges thereof to assist in such retention.
The keyboard module 30 is also provided at each side toward the upper end with a slot 90 which is adapted to receive tabs 92 of the key caption sheet 32 and tabs 94 of the transparent overlay sheet 34. The cooperating slots 90 and tabs 92, 94 function to hold the key caption sheet 32 and the transparent overlay sheet 34 in proper superimposed relationship to the keyboard module 30.
The key caption sheet 32 is positioned directly over the keyboard module 30, with the tabs 92 in the slots 90. With the sheet 32 so positioned, various indicia bearing portions of the sheet 32, such as areas 96 representing numeric keys of various values, and area 98 representing the "ENTER" key, are located directly over corresponding switch pads 40, so that pressure applied by the finger of a human operator on such area on the sheet 32 causes operation of the corresponding switch pad in the keyboard module 30.
The transparent overlay sheet 34 is positioned directly over the key caption sheet 32, with the tabs 94 in the slots 90 directly over the tabs 92 of the caption sheet 32. With the sheet 34 so positioned, the sheet 34 provides a transparent protective cover over the sheet 32. Areas of the sheet 34, such as the area 100, are defined by lines molded into said sheet, and correspond to the key areas such as 96 and 98 on the sheet 32.
When the keyboard 28 is to be assembled to the remainder of the housing structure of the terminal 20, the keyboard module 30 is moved into operative relationship with the opening in the housing of the terminal 20, so that the cut-away portions 79 on both sides of the module 30 receive the tabs 82 and 84 on the housing 22 and the side piece 26, respectively. The module 30 is then shifted toward the top 24. This causes the projections 80 to move beneath the tabs 82, 84, and causes the tabs 76 to move into engagement with the slots 78 on the top 24. In addition, the connector 42 on the module 30 mates with the connector 44 within, the terminal 20 and establishes electrical connection between the module 30 and the remainder of the terminal. The sheets 32 and 34 are then superimposed on the module 30 and the tabs 92 and 94 of said sheets are positioned in the slots 90 of the module 30.
After the assembly of the module 30 and the sheets 32 and 34 is in position, the bezel 36 is added in order to close the gaps present between the assembly and the surrounding upper edges of the housing 22, the top 24 and the side piece 26. Projections 102 of the bezel 36 are located in openings 104 in the top 24, and the bezel 36 is rotated downwardly until integral plastic latches 106 on the underside of the lower end of the bezel engage with retainers 108 on the inside surface of the front end of the housing 22 of the terminal 20, to lock the bezel 36 in place.
With the keyboard 28 fixed in position, the access aperture to the interior of the terminal 20 is closed, and the various elements of the exterior provide a secure housing with no access to the interior. Also the power supply circuit is completed, thus enabling the terminal 20 to function. When the keyboard 26 is removed, in order to provide access to the terminal interior for repair or maintenance, or for some other reason, the bezel 36 is first removed by prying up its lower or front edge against the flexible engagement of the latch 106 with the retainer 108, and then shifting the bezel so that the tabs 102 are moved out of engagement with the openings 104. With the bezel removed, the sheets 32, 34 can be taken off the keyboard module 30, and said module can be shifted so that the connectors 42, 44 are separated and the tabs 76 move out of engagement with the slots 78. The projections 80 move out from under the tabs 82, 84, and the keyboard module can be lifted away from the remainder of the housing of the terminal 20 to provide access to the interior thereof.
