ABSTRACT:
The present invention provides a sheet feeding mechanism for high-speed sheet feeding in succession at exact timing. The mechanism has output signal generating device for generating reference signals for sheet feeding, control device for releasing a rotary member from stopped state in response to the reference signal, an eccentric cam driven by the rotary member when it is in the rotation state and a rocking member to be driven by the eccentric cam, an end portion of rocking member for stopping the sheet material being positioned at the upstream or downstream side of constantly rotated members such as paired rollers in the sheet feed path to control the sheet feed timing by the rocking motion of said end portion of the rocking member.
