Abstract:
1. A sheet feed device comprising: a motor configured to selectively rotate in a first direction and a second direction opposite to the first direction; a first tray configured to store a first sheet therein; a second tray configured to store a second sheet therein; a first rotary member configured to feed the first sheet in a sheet feed direction; a second rotary member configured to feed the second sheet in the sheet feed direction; a first transmitting mechanism configured to transmit a rotational force of the motor in a first transmitting direction, wherein the first transmitting mechanism comprises an upstream portion connected to the motor, and a downstream portion connected to the first rotary member; a second transmitting mechanism configured to transmit the rotational force of the motor in a second transmitting direction, wherein the second transmitting mechanism comprises an upstream portion connected to the motor, and a downstream portion connected to the second rotary member; a first idling mechanism; and a second idling mechanism, wherein when the motor transitions between rotating in the first direction and rotating in the second direction, the first idling mechanism is configured to allow the upstream portion of the first transmitting mechanism to perform an idle rotation with respect to the downstream portion of the first transmitting mechanism, and the second idling mechanism is configured to allow the upstream portion of the second transmitting mechanism to perform an idle rotation with respect to the downstream portion of the second transmitting mechanism.
