Abstract

PURPOSE:To arrange a mechanism capable of selecting a disk and playing a program of the selected disk in a small space by providing this disk replacing type player with a reproducing unit for moving a disk extracted by dividing movement to a playing position. CONSTITUTION:When a magagine M storing plural disks D1 to D3 is loaded onto the player, the magagine M is divided in the thickness direction. Since a dividing space S2 occupies the whole area of the plane of the magagine M, a reproducing unit 3 is waited on a position deviated from the space S2. At the time of completing the division of the magagine M, the unit 3 is moved into the space S2 up to a playing position, and on the playing position, any one of disks in the divided magagine is clamped and played. Since the extraction side front edge Ma of the magagine M is opposed to the unit 3 through an interval delta, the magagine M loaded from the A direction does not interfere with the unit 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc exchangeable player that allows selection of a plurality of discs and playback of the selected disc within a housing that takes up minimal space.

[Conventional technology]

2. Description of the Related Art So-called disc changers, which are capable of selecting and playing a plurality of discs, have become popular as in-vehicle or home audio equipment.

Conventional disc changers are loaded with a magazine containing multiple discs, but the device includes a disc selection mechanism that selects and takes out a desired disc from the magazine, and a disc selection mechanism that clamps the selected disc. A playback unit that plays music is housed there. Furthermore, an on-vehicle disc changer is provided with an operating device called a commander that issues a disc selection command or performs programming for selection.

[Problems to be Solved by the Invention] However, in the conventional disc changer described above, it is necessary to provide a space for loading a magazine containing a plurality of discs, a space for a selection mechanism, and a space for a playback unit within the housing. Therefore, there is a limit to how small the changer housing can be made. Therefore, when used in a vehicle, the changer casing is installed in a trunk room or the like, and the commander is installed inside the vehicle. This not only reduces the space in the trunk, but also makes handling extremely inconvenient as the trunk must be opened every time a magazine is replaced.

The present invention solves the above-mentioned conventional problems, and provides a disc-exchangeable player in which a magazine, a playback unit, etc. can be arranged in a minimum space, and can be mounted, for example, on an automobile instrument panel. It is intended to.

[Means to solve the problem]

The disc exchange type player according to the present invention has a loading space into which a magazine into which a plurality of discs can be inserted and which can be divided in the thickness direction along with each disc is loaded, and a division space in which the magazine is divided in the thickness direction by a division mechanism. and a performance position which is in a standby position where it is removed from the division space when the magazine is divided by the division mechanism, and which moves toward the division space after the magazine is divided and plays any of the discs taken out by the division. The apparatus is characterized in that it is provided with a reproducing unit that moves to.

[Operation J] In the above means, when a magazine containing a plurality of disks is loaded, the magazine is divided in the thickness direction by the dividing mechanism. Since the dividing space at this time covers the entire plane area of the magazine, at this time the playback unit is placed on standby at a position outside the dividing space, and when the magazine division is completed, the playback unit moves into the above dividing space. The disc moves to a performance position, where one of the discs in the divided magazine is clamped and a performance is performed.

12b.

13b and is inserted into the magazine M, and the protrusion 16a
rises above the partition plate 13. Then, when the divided lifting plate 2 is lowered with the protrusion 16a in the direction indicated by fb) in FIG. However, since the hole 11a of the bottom plate 11 does not have a recess in the fb1 direction, the protrusion 16a is locked to the bottom plate 11. When the divided elevating plate 2 is lowered in this state, only the bottom plate 11 is divided at the joint B1 and lowered together with the disk D1. In addition, when the protrusion 16a descends in the direction C1 with the dividing shaft 16 inserted, the protrusion 16a moves into the hole 13 of the partition plate 13.
It passes through the recess 13d of a and is locked to the partition plate 12 that does not have a recess in this direction. When the divided elevating plate 2 is lowered in this state, the partition plate 12 is divided at the joint B2, and the partition plate 12 and the bottom plate 11 are integrated and lowered together with the disk D. Furthermore, when the protrusion 16a is oriented as shown in (d) with the dividing shaft 16 inserted, the partition plate 13 is locked to the protrusion 16a, and at this time, the partition plate 13 is separated from the ceiling plate 14 at the joint part B. Then, the partition plate 12 and the bottom plate 11 are lowered together with the disk D while being combined.

Next, the overall operation will be explained.

First, when the magazine M is inserted, the playback unit 3
is in the standby position shown in (A), and the divided elevator plate 2 is lowered. When the magazine M is loaded, the magazine M is held by a holding mechanism (not shown). In addition, if a locking mechanism is provided in the parts indicated by E and F of the magazine M,
The lock is released at the same time as loading, and the bottom plate 11 and the partition plate 1
2 and 13 as well as the ceiling plate 14 are mutually free.

For example, the case of playing back a disc D will be explained.

First, the divided lifting plate 2 rises, and at this time, the protrusion 16a of the divided shaft 16 is oriented in the direction (a).After the six divided shaft 16 is inserted into the magazine, the protrusion 16a of the divided shaft 16 is oriented in the direction (a). The divided elevator plate 2 descends in the direction shown in (b).

As a result, when the bottom plate 11 is divided at the joint portion B, the disk D1 and the disk D1 descend together within the divided space S wing. In this lowering process, while the bottom plate 11 is on the divided lifting plate 2, the disk D
When it reaches the height indicated by H in FIG. 2, the tip of the disk D1 protruding from the position of the front edge Ma by the holding claws (a plurality of them are provided) indicated by the reference numeral 20 in FIG. is retained. Therefore, only the bottom plate 11 is lowered thereafter, and the bottom plate 11 moves to the lowest position as shown in FIG.

After the bottom plate 11 is lowered, the reproduction unit 3 is moved to the performance position indicated by (b) by the mechanism shown in FIG. Then, the holding claw 20 moves diagonally upward in FIG. 1, and the disc D1 reaches the position (d), its center aligns with the center of the turntable 3b of the playback unit 3, and the disc D1 is clamped by the clamper 3d. . Then, reproduction is performed by the optical head 3e.

When the playback is completed, first the disc D is removed by the clamper 3d.
The clamp of I is released, and the holding claw 20 holds the disc D.
1 is returned to position (c). At the same time or before or after this, the reproduction unit 3 moves to the standby position shown in (A). Then, the divided lifting plate 2 rises, and in FIG.
The disk D is returned onto the bottom plate 11 at a height of .

The holding by the holding claws 20 is released, the divided elevating plate 2 is further raised, and the bottom plate 11 is assembled to the magazine M.

The above operation is similar for other discs. For example, when playing disc D8, with the split shaft 16 inserted into the magazine M, the protrusion 16a is
The partition plate 12 descends in the direction of l, and the bottom plate 11 and the partition plate 12
is divided and descends. Then, the disc D is held by the holding claws 20 at the height position H in FIG.

In the above embodiment, three disks are stored in the magazine M, but it may be two or four disks.Furthermore, the device of the present invention can be used for home or office use, for example, with the optical head 3e. If it has a recording/reproducing function, it can also be used as an optical memory device.
