[0005]

As described above, the tray for inserting and holding the cartridge of the conventional disk loading device is formed in a quadrangular hollow frame shape, and the operation plate body engaged on both sides thereof is moved by the moving operation. Since it is moved in the front-rear direction and the elevating direction, it is necessary to match the phase of the engaging portion with the movable plate on both sides, but it is difficult to match the phase due to the displacement of the support pins on both sides, etc. In addition, since the tray itself is formed in a hollow frame shape, the number of parts is large, the cost is high, and the weight is heavy and the driving force is large.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and has been made in consideration of the above circumstances, and has been made to reduce the cost by reducing the number of components of the tray itself by eliminating the phase adjustment of the moving mechanism on both sides of the tray. An object of the present invention is to provide a device for loading a cartridge containing a medium.

[0007]

In order to achieve the above-mentioned object, an apparatus according to the present invention comprises a pair of cartridges arranged on both sides of a cartridge in which a recording medium to be inserted is stored and holding both sides of the inserted cartridge. A tray, a plurality of support pins provided so as to protrude from the side surfaces of the pair of trays, and a pair of supports each having a guide groove engaged with the plurality of support pins to guide the tray to move in the front-rear direction and the up-down direction. A side plate, a pair of operating plate members which are supported by the pair of supporting side plates so as to be movable in the front-rear direction, and which have cam slots in which the support pins of the tray are respectively engaged; A drive mechanism for guiding the pair of trays by the support pins and the guide slots to load the recording medium contained in the cartridge into the recording / reproducing mechanism. It is. Further, in the above configuration, a rack portion is formed on each of the pair of operation plate bodies, and the drive mechanism is configured to include a pair of gears meshing with each rack portion and a pair of gears and a rotating shaft provided on both sides and a pair of gears. And a drive gear that rotationally drives one of the gears.

[0008]

In the apparatus of the present invention constructed as described above, the tray for inserting and holding the cartridge is divided into two sides so as to hold only the both sides of the cartridge. The supporting and moving mechanisms are separately assembled, and after this mounting, a synchronous drive mechanism is mounted on both operating plates, so there is no need to align the phases of both trays and the supporting and moving mechanism, simplifying the mounting process. In addition, since the tray itself does not include the intermediate portion, the number of parts is reduced, and the cost can be reduced.

The optical disk D accommodated in the inside is mounted.

On the other hand, above the trays 2a and 2b, a chucking plate 19 for holding the optical disk D between the turntable 18 and the tray 2a is arranged movably in the vertical direction so as to face the turntable 18. I have. The chucking plate 19 has a built-in magnet that is magnetically attracted to the iron turntable 18.
It is rotatably supported by a support bracket 21 via a bearing member 20. The support bracket 21 is supported by a top surface support plate 22 extending between upper edges of the support side plates 3a and 3b on both sides via a link mechanism 23 so as to be vertically movable. The chucking plate 19 is attracted to the turntable 18 to chuck the optical disc D on the turntable 18.

The operation of the disk loading mechanism constructed as described above will be described. First, in the initial state (before the disk cartridge 1 is inserted), the support pins 4a and 4b of the trays 2a and 2b are supported by the support side plates 3a as shown in FIG. , 3

When the operating plate driving motor 15 is operated and the operating plates 6a, 6b are moved rearward (in the direction of arrow a), the vertical edges 9a ₄ , 9b of the cam slots 9a, 9b are moved. ₄ comes into contact with and presses the support pins 4a and 4b of the trays 2a and 2b, so that the trays 2a and 2b are moved rearward integrally with the operating plates 6a and 6b. It is drawn back. Eventually, the support pins 4a and 4b will become the guide slots 5a of the support side plates 3a and 3b,
Vertical portion 5a ₂ from the horizontal portion 5a _1, 5b ₁ of 5b, 5b ₂
(The guide slots 5a and 5b are in the horizontal portion 5).
Since the corners between a ₁ , 5b ₁ and the vertical parts 5a ₂ , 5b ₂ are formed in a gentle arc shape, the support pins 4a,
4b is from the horizontal parts 5a ₁ , 5b ₁ to the vertical parts 5a ₂ , 5b ₂
In this state, the operating plates 6a and 6b are further driven rearward, whereby the support pins 4 are moved.
a and 4b are the inclined portions 9a ₁ and 9b _{1 of the} cam slots 9a and 9b.
Of the guide grooves 5a, 5b and moves downward along the vertical portions 5a ₂ , 5b ₂ of the guide slots 5a, 5b, that is, the trays 2a, 2b are lowered (FIG. 4).

As the trays 2a and 2b are lowered, the optical disk D in the disk cartridge 1 is placed on the turntable 18, that is, the disk loading operation is completed. In addition, the trays 2a, 2
The chucking plate 19 is also lowered at the same time as the lowering operation of the tray 2a.
b, the disk cartridge 1 enters the disk cartridge 1 and is magnetically attracted to the turntable 18 to hold the optical disk D under pressure, that is, the chucking of the disk is completed. When the loading operation and the chucking operation of the disk are completed in this manner, the disk becomes playable, that is, the optical disk is rotated by the driving of the disk drive motor 17 to perform reproduction (recording).

In the loading apparatus constructed as above, the trays 2a and 2b separated on both sides are separately supported by the supporting side plates 3a and 3b without being related to each other. The operating plates 6a and 6b for horizontal and vertical movements are composed of a rotating shaft 10 and pin-on gears 11a and 11b which constitute a synchronous drive mechanism.
The trays 2a and 2
b is moved integrally as in the case of the integrated tray, and the loading and unloading operations of the disk are performed.

As described above, according to the loading device of the present embodiment, the tray for inserting and holding the disk cartridge is separated into two sides and formed as both side trays 2a and 2b. ,
Since the mounting to the trays 2a and 3b is performed with the operating plates 6a and 6b interposed separately,
It is not necessary to align the phases of the operating plates 6a and 6b with the operating plates 6a and 6b on both sides.
b and the operating plates 6a, 6b
It is only necessary to mesh the pinion gears 11a, 11b fixed to the rotary shaft 10 with the rack gears 12a, 12b formed in the above, so that the assembling becomes easy and the steps required for manufacturing and assembling are reduced. In addition, since the intermediate portion of the tray is omitted, the number of parts is reduced as compared with the conventional integrated tray, so that the cost of parts can be reduced, thereby achieving a significant cost reduction.

Although the embodiment in which the present invention is applied to the loading device of the disk player has been described above, the present invention is not limited to the disk player and can be widely applied to, for example, a video tape recorder and the like.

[0021]

As described above, in the loading apparatus according to the present invention, the trays for inserting and holding the cartridges are formed separately on both sides, so that the respective trays on both sides are separated without being in phase with the supporting operation member. The tray can be easily assembled and the work can be reduced, and the tray has a configuration without the middle part, so the number of parts is reduced by that much and the cost is reduced. It is possible to reduce the cost and to reduce the weight of the tray, thereby saving the driving mechanism.
