Abstract

The mount which holds a copier's magnetic brush developer accurately spaced to a moving photoconductor also allows the developer to (1) move vertically upward, as the developer's end walls locate on pins which are mounted to the copier frame, (2) move directly away from the photoconductor when the developer is subsequently pulled off these pins, and (3) thereafter slide out of the copier, for service and the like. Fig. 1 is a front view of magnetic brush developer 10, having four magnetic brush developer rolls which must be accurately spaced relative moving photoconductor 11. Developer 10 is supported by one or more pins 12 (Fig. 2) which are mounted at fixed positions on the frame of the copier (not shown).

Developer Mounting

The mount which holds a copier's magnetic brush developer accurately spaced to a moving photoconductor also allows the developer to (1) move vertically upward, as the developer's end walls locate on pins which are mounted to the copier frame, (2) move directly away from the photoconductor when the developer is subsequently pulled off these pins, and (3) thereafter slide out of the copier, for service and the like. Fig. 1 is a front view of magnetic brush developer 10, having four magnetic brush developer rolls which must be accurately spaced relative moving photoconductor 11. Developer 10 is supported by one or more pins 12 (Fig. 2) which are mounted at fixed positions on the frame of the copier (not shown). The back wall 13 of the developer includes openings which receive pins 12 when the developer is manually pushed into the copier. Fig. 1 shows a similar opening 14 in the developer's front wall 15. Opening 14 cooperates with a pin which is carried by a frame member (not shown) which is placed in position, and coupled to the copier frame, after the developer is in its operating position. When service personnel desire to service the developer, this frame member is first removed. The developer can now be pulled out of the front of the copier. In so doing, developer wall 13 disengages from pin 12 (Fig. 2), and the developer moves vertically down a small distance (see arrow 20 of Fig. 2). The developer's bottom wall 21 includes six spring-loaded ball feet, one of which is shown enlarged in F...
