Abstract
A cut sheet feeding mechanism for feeding a cut sheet from a sheet hopper to a platen roller which is rotated in a forward direction to further feed the cut sheet to a printer. The mechanism includes a pick-up roller for picking up a cut sheet from a sheet hopper by rotating in a forward rotary direction and a transmission for transmitting the rotary force of the platen roller to a pick-up roller in a manner such that the pick-up roller also rotates in the forward direction. The transmission includes a disabling device for disabling the transmission after the pick-up roller has fed the cut sheet from the hopper by a predetermined amount.
