ABSTRACT:
A feeding device has a rotative threaded shaft and a rotatable paper tray. A movable joint is attached to the rotative threaded shaft, and permitted to move on the shaft. The movable joint is coupled to one corner of the rotatable paper tray. A shaft drive plate is secured to the movable joint. In the vicinity of the rotative threaded shaft, is disposed a shifting shaft extending in the direction of movable joint movements, which is permitted to freely move in the direction. An engaging member to be depressed by engaging the shaft drive plate and a spring to urge the shifting shaft to be located in a predetermined position, are attached to the shifting shaft. On the other hand, in the feeding device main body, there are installed an action plate for making a forward or backward movement in response to a movement of the shifting shaft driven by the shaft drive plate and switch for performing ON/OFF operation in response to shifting positions of the action plate. Thus, this arrangement makes it possible to reduce the number of required parts for connecting the feeding device to the feeding device main body and for detecting operating conditions of the rotatable paper tray.
