ABSTRACT:
An electrophotographic copying apparatus with an original support table arranged on the top of the housing to carry out a reciprocating linear movement out of and back to a home position whereby a copy sheet moved in synchronism with the table is exposed line by line to the original. Transmission means for transforming the rotary motion of a drive motor into linear reciprocating movement of the table includes an elongated tooth rim with internal teeth arranged vertically on a carriage extending along one side of the table and a pinion engaging the teeth of said tooth rim and being secured at one end of a transverse drive shaft, the other end of which is engaged with a transmission chain coupled with the motor and being journalled to allow vertical shifting of the pinion to engage one or the other of parallel horizontal rims of the tooth rim, a guide wheel being secured on the first end of the drive shaft to engage an endless guide track formed inside the tooth rim in parallel relationship to the teeth rims thereof. The vertical shift movement of the drive shaft may be utilized for operating an electric switch to connect and disconnect current supply to an exposure lamp.
