PURPOSE:To enable to move a selected copying paper storage to the paper feeding system with minimum noise, by only turning directly or reversely at 90 deg. an index cam from the unfeeding position. CONSTITUTION:A two phase index cam 2 with shifted phases by 180 deg. is installed close to the copying paper storage 1. This index cam 2 has respective drive transmitting measures 4 (such as clutches). By turning the drive transmitting measures 4 on or off to turn these index cams directly or reversely selectively, a random copying paper storage 1 in the upper, middle or lower section can be selected to move to the paper feeding system. |
