Abstract
A sheet feed device installed in a copier or like recording apparatus for selectively feeding sheets in an automatic and a manual mode. The device include a sensor sensitive to a movement of a manual insertion tray to an operative position away from an inoperative one. When the sensor has sensed such a movement of the tray while a sheet cassette is in a sheet feed position, a drive mechanism which is driven by a DC motor shifts the sheet cassette from the sheet feed position to a standby position. The tray is made up of a front tray and a rear tray which is connected to the front tray in an upward rotatably manner. While the tray is attached to the sheet feed position, a tray guide guides the movement of the front tray to the sheet feed position.
