Abstract
A sub tray selector is provided in a casing and rotatable so as to adjust a selecting position in accordance with the height of a designated sub tray. The sub tray selector is capable of retaining the designated sub tray and any other sub trays stacked thereon and disengaging each of the retained sub trays from a sub tray engaging member in accordance with a shifting motion of a base tray advancing to the external position. Thus, the retained sub trays stay at the standby position.
Claims16
An automatic disc playback apparatus comprising
- a base tray shiftable between an external position located outside a casing and a standby position in said casing;
- a plurality of sub trays stacked on said base tray in an up-and-down direction for mounting a disc thereon, a position of each sub tray being selectable among three modes, wherein each of said sub trays is pulled out and located at said external position together with said base tray in a first mode, retained at said standby position in a second mode, and conveyed to a playback position located in said casing third mode;
- a plurality of guide grooves provided in said base tray and arranged in the up-and-down direction, respective ones of said guide grooves supporting each of said sub trays between said external position and said standby position;
- a sub tray engaging member provided in said base tray and elastically deformable so as to generate an urging force;
- a hook formed on each of said sub trays and being engageable with said sub tray engaging member under said urging force, while each of said sub trays is disengageable from said sub tray engaging member against said urging force when said sub tray is located at said standby position and said playback position;
- and
- a sub tray selecting mechanism provided in said casing and rotatable so as to adjust a selecting position in accordance with the height of a designated one of said sub trays, said sub tray selecting mechanism being capable of retaining said designated sub tray and any other sub trays stacked thereon and disengaging each of the retained sub trays from said sub tray engaging member in accordance with a shifting motion of said base tray advancing to the external position, thereby making said retained sub trays stay at the standby position.
