Abstract: A power switching device for switching power between translational motion and rotational motion includes an active gear, a transmission mechanism, a translation mechanism, a functional gear, and a reset mechanism. The active gear can rotate in a first direction or a second direction opposite the first direction. The translation mechanism includes a runner and a pushing member. The active gear can switch between a first position and a second position. In the first position, the active gear meshes with the runner and rotates in the first direction or the second direction to drive the runner to rotate. In the second position, the active gear meshes with the transmission gear and rotates in the second direction to drive the functional gear to rotate.

Abstract: A power switching device includes a translation mechanism, an active mechanism, and a transmission mechanism. The translation mechanism includes a rack. The active mechanism includes an active gear and a driver. The active gear connects with a first functional mechanism, and the driver drives the active gear to rotate in a first direction or a second direction. The transmission mechanism connects with a second functional mechanism. The active gear is switched between a first position and a second position. In the first position, the active gear is connected to the transmission mechanism and rotates in the first direction to drive the transmission mechanism to rotate, thereby driving the second functional mechanism to operate. In the second position, the active gear meshes with the rack and rotates in the first direction or the second direction to reciprocate on the rack so as to drive the first functional mechanism to operate.

Abstract: A paper feeding and sheet separating differential device comprises a rotating shaft, a first roller, a second roller and an insertion pin, in which the first roller is installed on one end of the rotating shaft and comprises a first outer frame and a first raised mass disposed on an inner side of the first outer frame; the second roller is put around the rotating shaft and comprises a second outer frame, an accepting hole disposed inside the second outer frame and used for receiving the rotating shaft, a groove extended axially from the accepting hole to the second outer frame and the second raised mass disposed on an circumference of the accepting hole and used for propping against the first raised mass. Furthermore, the insertion pin is passed through the rotating shaft and then received in the groove.
