Description

[Detailed description of the invention] [Industrial application field] This invention relates to a loading mechanism of an optical disk player, in particular, a single motor moves a tray and raises / lowers a mechanical deck, clamps an optical disk, and places an optical disk. The present invention relates to a loading mechanism that does not cause play between a tray that enters and exits and a tray guide.

[Prior Art] A conventional optical disk loading mechanism is shown in FIG.

In the figure, a tray 13 on which an optical disk is placed fits in a tray holder 14 during loading.

The pins 14a, 14a... Erected on the tray holder 14 pass through guide grooves 15a, 15a... Provided on the chassis 15 and guide grooves 16b, 16b.

A pair of sliders 16 are arranged on the left and right side surfaces of the chassis 15, and guide grooves 16a, 16a,.
Are slidably supported by the chassis 15. The guide pins 15b, 15b,.

The rack 16c formed on the slider 16 and the gear 17 mesh with each other, and the gear 17 is rotated to lower the tray 13,
The performance is performed by clamping the optical disc on the turntable of the fixed spindle motor.

[Problems to be Solved by the Invention] In the above-described conventional apparatus, a large space is required in a mechanism portion for moving a tray having a large area up and down, and a tray is moved from a tray guide for moving the tray into and out of the tray holder. However, there is a drawback that play is generated between the tray and the tray guide, and the cost is increased because two drive motors are used.

This invention has been made in view of the above points, and its purpose is to eliminate the need for a large space in the mechanism and to provide a play between the tray for loading and unloading the optical disc and the tray guide. It is to provide a low-cost loading mechanism that does not cause the problem.

[Means for Solving the Problems] The loading mechanism of the optical disk player according to the present invention has pins erected on a mechanical deck provided with a spindle motor for rotating the optical disk and an optical pickup for reading signals, and the pins are provided on a chassis. The drive mechanism driven by one motor 9 is inserted into the oblique guide groove of a first slider slidably supported by the chassis and disposed on the left and right sides of the mechanical deck with the vertical guide groove, and the first drive mechanism is mounted on the chassis.
A third slider provided on a second slider slidably supported in a direction orthogonal to the sliding direction of the slider and having a rack meshing with the gear of the drive mechanism is mounted on the chassis in a direction parallel to the second slider. And a stopper pin that fits into one of the respective recesses provided in the second and third sliders and stops one of the second and third sliders. Standing on the supported arm, the third stage immediately before the end of the tray transfer process performed by meshing the gear of the drive mechanism with the rack provided on the tray.
The third slider is fed by engaging the rack and the gear by a trigger gear provided on a gear meshing with the rack of the slider. When the recess of the third slider reaches the movement path of the stopper pin, the stopper pin is moved to the second position. The third slider is moved from the recessed portion of the slider to the recessed portion of the third slider so that the third slider is stopped and the second slider is moved. With the movement of the second slider, the gear of the driving mechanism is moved from the tray rack. The optical disc is clamped by moving the first slider in parallel and moving the first slider in parallel to raise the mechanical deck.

According to the present invention, when the optical disk is clamped on the turntable, the spindle motor rises together with the mechanical deck, so that there is no need to raise and lower the tray on which the optical disk is mounted, and the mechanism can be made compact. No play occurs in the tray transfer mechanism.

Further, the tray can be transferred and the disk clamped by one motor, so that the cost is reduced.

[Embodiment] A loading mechanism of an optical disc player according to an embodiment of the present invention will be described with reference to FIG.

In the figure, reference numeral 1 denotes a mechanical deck to which a spindle motor 2 is fixed, and which supports an optical pickup 3 via a feed mechanism.

The pins 1a, 1a,...
, And the guide grooves 5a, 5a,... Provided in the first sliders 5, 5 are inserted through the guide grooves 4a, 4a,.

The first sliders 5, 5 are supported by left and right side plates of the chassis 4 so as to be slidable in the front-rear direction, and have respective guide grooves 5a, 5
The rising directions of the gradients of a ... are opposite to each other.

The third slider 6 is slidably supported in the left-right direction by engaging grooves 6e, 6e provided in the third slider 6 with pins 6a, 6a provided upright on the chassis 4, and a rack 6b formed therein is provided. Can mesh with the gear 7 of the drive mechanism.

Reference numeral 8 denotes a gear that constitutes a drive mechanism, and transfers the tray meshing with a rack formed on a tray (not shown) in a direction orthogonal to the sliding direction of the third slider 6.

Reference numeral 9 denotes a loading motor, which transmits rotation to a driving mechanism including gears 7, 8, and the like.

The second slider 10 is slidably supported by the chassis 4 in the left-right direction by engaging grooves 10b, 10b provided on the second slider 10 with pins provided on the chassis. The second slider 10 has a motor 9 and a drive mechanism. ing.

The arm 11 is rotatably supported by a shaft 4b erected on the chassis 4 and has pins 11 erected on its left and right ends.
Reference numerals a and 11a are inserted into grooves provided in the first sliders 5,5, and pins 11b provided on the front end are inserted into grooves in the second slider 10.

The arm 12 is rotatably supported by a shaft erected on the chassis 4, and as shown in detail in FIG. 2, a pin 12 a erected on the arm 12 rotates the arm 12 in the direction of arrow A. Accordingly, it fits into either the concave portion 6d of the third slider 6 or the concave portion 10a of the second slider 10.

In the above configuration, when the pin 12a shown in FIG. 2 is fitted in the concave portion 10a of the second slider 10 and the second slider 10 is fixed, the tray on which the optical disc is placed is sent to the gear 8, When the optical disk is slightly closer to the clamp position, the gear 7 and the track 6b are engaged by the trigger gear 7a of the gear 7 and the trigger gear 6c of the rack 6b shown in FIG. Sent rightward as indicated by the arrow.

That is, the third slider 6 is fed in the direction of arrow B in FIG. 2, but the edge of the recess 6d of the third slider 6 is
When the pin 12a comes into contact with the second slider 10
The third slider 6 is fixed by being drawn into the concave portion 6d of the third slider 6 from the concave portion 10a.

 At this point, the tray comes to the optical disk clamp position.

Next, the second slider 10 is released from the lock by the pin 12a, and moves to the left (in the direction of arrow C in FIG. 2) by the engagement of the gear 7 and the rack 6b, so that the gear 8 is separated from the tray rack. , The tray stops. Then, the second slider 10 rotates the arm 11 clockwise, and the arm 11
Are moved forward and backward, respectively.

 The first sliders 5, 5 raise the mechanical deck 1.

The turntable 2a fixed to the rotating shaft of the spindle motor 2 fixed to the mechanical deck 1 lifts the optical disk from the tray, and a clamp mechanism disposed above the optical disk presses the optical disk against the turntable 2a to perform a performance. .

When ejecting the optical disk, the drive motor 9 rotates in the opposite direction to lower the mechanical deck 1, and then moves the tray out of the machine.

According to the loading mechanism of the optical disk player of the present invention, when the optical disk is clamped on the turntable, the spindle motor rises together with the mechanical deck, so that there is no need to raise and lower the tray on which the optical disk is mounted. Can be made compact.

In addition, since there is no play in the tray transfer mechanism, the quality of the product is improved.

Furthermore, the cost can be reduced because the tray can be transferred and the optical disc can be clamped by one motor.
