Abstract

(57) [Summary] [Object] The present invention relates to a tray mechanism of a disc reproducing apparatus, and an object thereof is to prevent a disc from being displaced when the tray is moved by providing a lever with a disc positioning lever mechanism. A lever 15 having a boss 13 that is swingably supported on a lower portion of a tray 8 in which a disc 18 is housed and fits into a central hole of the disc 18, and the lever 15 hits the disc when the tray moves. It is configured to include a contact member 17 for separating the boss 13 from the center hole of the reproducing device.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tray mechanism of a disc reproducing apparatus, for example, an auto changer type disc reproducing device for selecting and reproducing a desired disc from a plurality of discs stored in a cabinet by a disc player which moves vertically and horizontally. In regard to the tray mechanism in.

[0002]

[Prior art]

 Conventionally, a plurality of discs are stored in a plurality of trays that can be freely moved in and out provided on a shelf of a box-shaped cabinet, a desired disc is selected, and a tray storing the disc is moved to put the disc in a player. 2. Description of the Related Art There is known an auto changer type disc reproducing apparatus which is adapted to be reproduced by a sending player.

[0003]

[Problems to be solved by the device]

 However, in such a disc reproducing apparatus, when the tray moves, the disc may move in the tray and the disc may be displaced, which may cause the disc to be detached or may hinder the auto change function. The present invention has been made in view of the above problems of the conventional technique, and provides a tray mechanism in a disc reproducing apparatus in which the disc positioning mechanism is provided in the tray to prevent the disc from being displaced when the tray is moved. The purpose is to

[0004]

[Means for Solving the Problems]

 According to the present invention, a lever having a boss that is swingably supported on a lower portion of a tray in which a disc is housed and fits into a center hole of the disc, and the lever contacts the center hole of the disc when the tray moves. It is characterized in that it is provided with a contact member for separating the boss.

[0005]

[Operation] Since the boss is fitted in the center hole of the disc when the tray storing the disc moves, the disc does not move in the tray. When the cam surface at the tip of the lever hits the contact member, the lever swings and the boss descends to separate from the disc.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing an embodiment of the tray mechanism of the disc reproducing apparatus of the present invention. First, the configuration will be described. In FIG. 1, reference numeral 1 denotes a main body case of the disc reproducing apparatus 100. The main body case 1 is provided with a storage rack 2 (or cabinet) of a large number of trays at its front part, and a disc player 3 (at the rear of the storage rack 2). Hereinafter referred to as a player). Although the storage racks 2 are provided in two rows in the illustrated embodiment, they may be arranged in any number of rows, and the number of stages is not limited.

The player 3 is attached to a movable table 4 so as to be movable in the left and right directions. A rack gear 5 is fixed to the moving table 4 and meshes with a pinion gear (both not shown) rotated by a motor provided inside the player 3, and the player 3 is moved left and right by driving the motor. It is supposed to be done.

A pinion (not shown) that meshes with a vertical rack gear 6 is attached to the movable table 4, and the movable table 4 is also moved vertically by driving the pinion with a motor (not shown). It is supposed to do.

The storage rack 2 stores a tray 8 in which a disk 18 is stored (in FIG. 1, only the uppermost tray is shown). The tray 8 is adapted to be pulled into the player 3 by a gear 9 provided on a side portion of each accommodation rack 2. 2 and 3, the tray 8 has a disc mounting portion 11 at the center of a main body 10, a hole 12 is formed in the disc mounting portion 11, and a positioning boss 13 is formed in the hole 12. It appears to appear and disappear. The boss 13 is provided on an L-shaped lever 15 supported by a shaft 14 on the lower surface of the tray 8. A cam surface 16 is formed at the tip of the lever 15.

A hitting member 17 is attached to the lower part of the side of the player 3 behind the tray 8. When the hitting member 17 moves in the direction of the player 3 after the player 3 stops at a predetermined position. The cam surface 16 of the lever 15 comes into contact. As shown in FIG. 3, normally, the weight of the lever 15 on the cam surface 16 side of the shaft 14 is larger than that of the boss 13 side, and the boss 13 projects upward from the hole 12 of the tray 8. Therefore, when the disc 18 is placed on the tray 8, the boss 13 is fitted in the center hole of the disc 18.

Next, the operation will be described. When the player 3 comes to the position of the selected desired disc, the tray 8 in which the disc is stored moves toward the player 3. At this time, since the boss 13 is fitted in the center hole of the disc 18, the disc 18 does not move in the tray. Then, when the cam surface 16 at the tip of the lever 15 hits the contact member 17, the lever 15 swings around the shaft 14 as a fulcrum, the boss 13 descends and is disengaged from the disc 18, and the disc is fed into the player 3. Therefore, the disc 18 can be prevented from being displaced from the tray 8 when the tray 8 is moved, and the disc 18 can be stably placed on the tray 8.

[0012]

[Effect of device]

 As described above, according to the present invention, a lever having a boss that fits into the disc center hole is provided at the bottom of the tray to disengage the fit when the tray moves, so that when the tray is moved or the rack is moved. Therefore, the disc will not move in the tray during storage, and the disc can be stably stored in the tray of the disc reproducing device even when the tray moves and the disc reproducing device moves.
