Abstract

1,215,091. Coil clutches. RICOH K.K. 12 Feb., 1968 [16 Feb., 1967], No. 6763/68. Headings F2C and F2L. The drive for a sheet feeding device of a copying machine comprises a drive sprocket 12 which can be coupled to a driven sprocket 10 on a shaft 4 by contracting a clutch coil 14 on to the end of the shaft by engaging a brake member 18 against the flange 13 of a sleeve enclosing the spring 14. The member 18 is spring loaded on a bell crank 17 connected to the plunger 15a of a solenoid 15 operated by a microswitch in the path of movement of the sheet.
