ABSTRACT:
An electromagnetically operated sheet diverter for an image forming apparatus. The sheet diverter diverts a sheet from a common path to one of two possible paths upon discharge from the image forming apparatus. The sheet diverter is small and compact, making the sheet diverter suitable for desktop image forming devices. A main controller operates the sheet diverter to divert sheets depending on the tray of origin. The sheet diverter has a holding bracket. An electromagnet is mounted to the holding bracket. A spring-biased paper diverting member is selectively attracted by and brought into contact with the electromagnet only when the magnet is activated. A longitudinal shaft is tightly held by the paper diverting member and is selectively rotated along with the paper diverting member. The longitudinal shaft has a plurality of fitting grooves, which are spaced out at regular intervals and have a D-shaped cutting configuration. A passage switching member is fixed to each fitting groove of the longitudinal shaft and is selectively rotated by the magnet thereby switching the paper passage between the document passage and the copy paper passage.
