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.

Abstract translation: 进给装置具有旋转螺纹轴和可旋转纸盘。 可动接头连接在旋转螺纹轴上，允许在轴上移动。 可移动接头联接到可旋转纸盘的一个角。 轴驱动板固定在可动接头上。 在旋转螺纹轴附近设置有沿可动接头运动方向延伸的变速轴，允许沿该方向自由移动。 通过接合轴驱动板而被压下的接合构件和用于推动变速轴位于预定位置的弹簧被附接到变速轴。 另一方面，在进给装置主体中，安装有用于响应于由轴驱动板驱动的换档轴的运动和用于响应地进行ON / OFF操作的开关而进行向前或向后运动的动作板 以移动动作板的位置。 因此，这种布置使得可以减少用于将馈送装置连接到馈送装置主体的所需部分的数量，并且用于检测可旋转纸盘的操作条件。
