Abstract

PURPOSE: To offer a release mechanism of gears which secures the driven part including a development roller by making it free from the drive part with an easy procedure at any necessary time for ex., when a sheet is wrapped round the development roller.
CONSTITUTION: In the state the development roller 7b is rotating, the working faces 32, 32a, 32b of a rotary cam 19 are in contact with the working faces 31, 31b, 31a of a slide cam 20, respectively, and the intermediate gear 10 is pressed against the side face of the slide cam 20 by the action of the elastic force of a spring 16 as well as in engagement with the drive gear 9 and driven gear 11. When the control lever 18 is, under this condition, turned to the position of broken line, a switch for power supply situated outside the illustration is turned off, ceasing the revolution of the drive gear 9 as well as separating the pressure roller, outside the illustration, from the development roller 7b. At the same time, turn of the arm 19 round the shaft 15 heaves the slide cam 20 through the rotary cam 19 and separates the intermediate gear 10 from the driven gear. Thus the roller 7b is put into the free state.
