Abstract

Copier process stations and electronics, such as power supplies, circuit boards, etc., are mechanically formed into discrete modules and electrically interconnected such that each module can be individually replaced, but must be properly placed and closed relative to the other modules before the machine will operate.

Electrical Connections in a Modularized Compact Copier

Copier process stations and electronics, such as power supplies, circuit boards, etc., are mechanically formed into discrete modules and electrically interconnected such that each module can be individually replaced, but must be properly placed and closed relative to the other modules before the machine will operate.

The functional modules through the center of the copier are shown in operating position in Fig. 1 and swing out ready for removal in Fig. 2. Image module 10 contains the illumination lamps 11 and fiber optic bundle 12, the final charge corona 13 and original document driving rollers 14A - 14C. Rollers 14 cooperate with pivotal cover module 15 to form a single sheet feed mechanism. A closed-loop recirculating document feed path can be included in cover module
15. The copy sheet paper path module 20 contains the precharge/transfer corona in area 21, the hot roll fuser and lamp generally located at 22 and the copy paper picking mechanism with solenoid generally located at 23 for extracting paper from cassette 25. Developer module 30 is the cleaner/developer with its magnetic brush 31 and toner replenisher.

The central modules are held in place between frame member 16 (Fig. 2) and electronics module 40, shown in Fig. 3. Module 40 is attached to an AC power cord (not shown) and further includes power supplies 41, circuit boards 42A - 42D for mounting various logic elements, such as 43, and generally everything electrical except lamps, switches, solenoids and the like necessarily located in other modules. Electronic module 40 also includes electrical edge connectors 44A - 44F, with appropriate connections being made to 44A - 44E when module 40 is placed in the machine. Connector 44F attaches to a ribbon cable at 19 (Fig. 2) to provide connections to switch and display elements mounted on the far side of frame member 16. Other connectors, such as 45, are made when the associated process modules are pushed or lowered into place. Various machine cover panels enclose all modules when they are in place. It...
