Abstract

The CRT display terminal shown above is designed to be serviced with an "element exchange" philosophy, wherein the design includes a number of easily removable (by hand) modules or elements. This allows the customer to return failing elements for repair and to replace repaired elements with no intervention by service personnel. The elements are: 1. Logic Element A -- This element contains one of four logic card combinations and a cover. The cover acts to provide both physical protection and a stiffening member for the logic card, in addition to functioning as a decorative enclosure when assembled to the display element. To provide for ease of element exchange, two hand-operated (no tools required) latches A1 are incorporated in the cover.

Packaging Technique for an Element Exchange Terminal

The CRT display terminal shown above is designed to be serviced with an "element exchange" philosophy, wherein the design includes a number of easily removable (by hand) modules or elements. This allows the customer to return failing elements for repair and to replace repaired elements with no intervention by service personnel. The elements are: 1. Logic Element A -- This element contains one of four logic card combinations and a cover. The cover acts to provide both physical protection and a stiffening member for the logic card, in addition to functioning as a decorative enclosure when assembled to the display element. To provide for ease of element exchange, two hand-operated (no tools required) latches A1 are incorporated in the cover. The operator is thus presented with an easily removable package that offers a large degree of protection to the logic card retained within. In addition, the cover, which is also an external machine cover and a decorative part, presents the minimum size external appearance. 2. Display Element B -- The display element contains a multifunction chassis B1 which supports the CRT B2, analog circuitry B7, a power supply B3, decorative covers B4, and hardware B5 providing ergonomic height and tilt adjustment. Chassis B1 is a single stamping which provides mounting for the above hardware at lower cost than would an assembly of many individual parts. In addition, assembly is more easily accomplished; the chassis acts as its own assembly pallet, and tolerance controls possible on a single piece stamping are consistent with automatic assembly. The CRT B2 is mounted to the chassis via four identical brackets (not shown) which allow mechanical adjustment to the decorative bezel B6, the bezel itself being mounted directly to the chassis. Analog circuitry is housed on a logic card B7 mounted directly to the bottom of the chassis. This concept allows: -Access to adjustments on the component side of the card. -Direct plugging to power supply B3, without any cables. -Access to ergonomic hardware B5. -Better convective cooling for both the analog card and power supply than if the analog card were top- or side- mounted. -The best utilization of space for the size of the card. Because of component size, to...
