Embodiment Construction

[0069] the whole frame

[0070] An embodiment of the present invention will be described in detail below. The same structures as those of the conventional device will be assigned the same reference numerals as those of the conventional device and they will not be described in detail.

[0071] Fig. 1(a), (b) and (c) are side views schematically showing the device of the present invention. A layered stacking cabinet 7 is arranged on the side of the device close to the user's operation of the device, and several disc trays 4 that are stacked up and down and are each suitable for carrying a CD are accommodated in the layered stacking cabinet 7 . Each disc holder 4 is contained in the corresponding layer on the layered stacking cabinet 7 and can move in and out of the layered stacking cabinet 7 . Arranged in front of the layered stacking cabinet 7 is a recording-reproducing unit 2, which can move up and down in a state of threaded engagement with three screw rods 61, 61, 61 pr...

Abstract

Provided forwardly of a stacker accommodating trays in a plurality of stages for placing a disk on each tray is a recording-playback unit which is movable upward and downward for recording or reproducing data on or from the disk. A clamp plate covering the recording-playback unit is pivoted to the unit. When one of the trays is to be ejected from the stacker, the recording-playback unit is moved upward or downward to a level where the disk carrying face thereof is displaced from the tray to be ejected, to block the path of movement of the tray to the recording-playback unit with the clamp plate or the recording-playback unit, and the tray is thereafter ejected.

Description

technical field [0001] The present invention relates to an optical disc recording-reproducing apparatus for recording data on an optical disc and reproducing data recorded on the optical disc, a disc tray used on the apparatus, and an ejecting method of the disc tray. Background technique [0002] The applicant has proposed a Figure 43 An optical disc recording-reproducing apparatus as shown (see JP-A-297904 / 1996). This previously proposed device has a stacker 7 on its main body 100 which accommodates several layers of trays 4 for placing a disc on each tray. Arranged at the front of the stacker 7 is a holder 700 movable up and down for placing the disc tray 4 delivered from the stacker 7 thereon. Below the up-and-down movement path of the holder 700, a recording-reproducing unit 2 is arranged. [0003] Such as Figure 43 As shown, the disc tray 4 can be moved in and out of the stacker 7 to the right—that is, in the loading direction and to the left—that is, in the ejecti...
