This disk loading device is capable of reproducing a plurality of disks. A power transmission to drive gears is switched by tooth omission gears of a control gear so that angular movement of a disk playing portion, as well as movement of a tray base in a non-reproducing position and a reproducing position of the disk playing portion, can be effected by a single motor. A close lock gear, which prevents movement of the tray base in a disk reception stop positions, limits position of the drive gears. With this arrangement, when each tooth omission gear of the control gear enters the teeth of the corresponding drive gear, the interference of the teeth is eliminated. With this construction, the number of component parts such as a drive motor is reduced, thereby achieving a compact design and a stable operation.

Single motor disk loading device with lock gear

The rotary motion of a driving cam driven by a driving motor is converted into both the upward and downward movement of a deck member and the forward and backward movement of a tray, so that the deck member and the tray can be driven by a single motor. Further, the conversion into the upward and downward movement of the deck member and the forward and backward movement of the tray is performed by the engagement of a pin of the driving cam with a straight groove and a circular groove of a driving lever. Since the straight groove is extended in the tangential direction of the driving cam, when the pin engages with the straight groove, the driving lever receive a force to slow down the opening and closing speed of the tray at the beginning and end of the movement, thereby improving the quality of the loading operation.
