Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention stores a plurality of discs such as video discs and audio discs, takes out any disc, and loads it into a recording and/or playback device. The present invention relates to a disc loading device.

[Summary of the invention]

The disc loading device according to the present invention stores a large number of disc trays for placing and holding discs in a stacked manner, and uses a moving mechanism and a clamp mechanism installed in an elevating mechanism that moves up and down to load any disc tray into the storage area. By pulling out the disk into the drawer section located on the front side of the disk drive and clamping the disk held on the disk tray to load it into a predetermined position, any desired disk can be loaded reliably and smoothly. It is something.

[Conventional technology]

Conventionally, in playback devices for video discs, audio discs, etc., so-called karaoke machines store a large number of discs, and have a loading device that takes out any one disc from among the discs and loads it into the playback mechanism. A disc autochanger player is used.

[Problem to be solved by the invention]

In conventional disk loading devices of this type,
A mechanism for pulling out any one disc from a large number of stored discs and a clamping mechanism for clamping and transporting the pulled out disc are configured to move independently in response to the stored discs. .

However, the movement operations of the disk pull-out mechanism and the clamp mechanism must be timed to avoid damaging the disk, and this adjustment requires time and effort, and the structure is complicated and costly.

The present invention has been made in view of the above, and an object of the present invention is to provide a disk loading device that has a relatively simple configuration and is capable of reliably loading any disk from a large number of stored disks.

[Means to solve the problem]

In order to achieve the above object, a disc loading device according to the present invention includes a storage part in which a plurality of disc trays for placing and holding discs are stored in a stacked manner, and a storage part located in front of this storage part, in which the disc tray is pulled out. a moving mechanism that reciprocates the disc tray between the storage part and the drawer part, and a clamp mechanism that clamps the disc on the disc tray pulled out to the drawer part and can turn it upside down. and an elevating mechanism in which a moving mechanism and a clamping mechanism are installed, and which moves both mechanisms up and down so as to correspond to an arbitrary disk tray.

[Effect]

With this configuration, the movement mechanism and clamping mechanism of the disk tray can be moved up and down by the drive of the elevating mechanism with respect to a large number of disk trays on which disks are placed and stored in a stacked manner in the storage section. By moving the two mechanisms in unison with the disc tray, the timing of pulling out the disc tray and clamping the disc tray is always reliably matched, so that the disc can be loaded smoothly without fear of damage.

Further, since the moving mechanism and the clamping mechanism have a common moving means, that is, a lifting mechanism, the structure is simplified.

The state in which the movement of the disk tray (2) is completed, that is, the front end side supports (2a) and (2b) of the disk tray (2)
(59) and a sensor (60) provided at the tip of the elevator body (12a) are engaged with and supported by the support protrusions (8a) and (8b) of the front wall plate (7). )
This signal causes the plunger solenoid (24) to return, and the drive gear (16a) of the gear mechanism (16) to move towards the disc tray (2).
) and out through the window holes (5a, ), thereby keeping the disc tray (2) stationary.

On the other hand, in this state, the clamp mechanism (10) provided on the arm base (28) has the upper and lower link pieces (38a) and (38b) of the clamp link mechanism (38) connected to the rod (35).

The lower link piece (38b) and the disc base (34) cause the disc tray (2) to be pulled out and stopped.
The upper disk D is clamped, that is, the disk D is held with a clamp.

In this state, the second gear mechanism (1
7) corresponds to the pulled-out disc tray (2), where the second plunger solenoid (25
), the drive gear (17a) of the second gear mechanism (17) meshes with the rack (26) of the disc tray (2), and by driving this gear mechanism (17) in the opposite direction, the disc tray (2) is returned from the drawer part (4) to the storage part (3), and the disc D is moved by the clamp mechanism (
10), and is kept in the drawer part (4).

Thereafter, the arm base (2) is reversed by rotating the rotary drum (27) by the geared motor (44), and the clamp mechanism (10) that clamps and holds the disk D is rotated.

) is faced. That is, the disc D clamped by the clamp mechanism (10) faces the tray (61a) which is pulled out from the playback device (61) to the lower part of the drawer part [4] of the chassis (1).

In addition, in this state, the plunger solenoid (25) on the gear mechanism (17) side is returned, and the drive gear (17a) is removed from the rack (26) of the disk tray (2).
It is going out through the window hole (5a,).

In this state, the elevator (12) is lowered by the drive of the motor M, and the disc D clamped by the clamp mechanism (10) is placed on the tray (61a) of the playback device (61).
When the elevator reaches a state where it is almost in contact with the top, the elevator (12)

After that, the elevator (12) is moved upward to a desired position, that is, a position where the clamp mechanism (10) is separated from the disc D on the tray (61a) of the playback device (61), and then stopped and placed on the tray (61a). The disc D is fed into the playback device (61), the required playback is performed, and the playback device waits until it is ejected from the playback device (61).

Disc D is then transferred from the playback device (61) to the tray (6
1a), the elevator (
12) is lowered again and the clamp link mechanism (38) of the clamp mechanism (10) is inserted into the center hole d of the disk D, and its upper and lower link pieces (38a) and (38b) rotate the end cam (32). compressed coil spring (4

The empty disc tray (2) is pulled out to the drawer part (4) by the rotation of the drive gear (17a) driven by the crank link mechanism (38).
) is pulled out and positioned below the disk D which is held by a clamp. That is, when the clamp mechanism (10) is clamping the disk D in a downward state, the empty disk tray (2) is pulled out as it is below the disk D, and when the clamp mechanism (10) is clamping the disk D Empty disc tray (2) when clamped and flipped upside down
has a clamping mechanism (10) through its central opening (2c).
The disk base (35) is pulled out and placed under the clamped disk D.

In this way, the empty disk tray (2) is pulled out below the disk D clamped by the clamp mechanism (10), and in a state where it is stopped at a predetermined position as described above, the clamp link mechanism of the clamp mechanism (10) (38
) is driven to form the upper and lower link pieces (38a).
