Abstract

PURPOSE:To surely load a disk without causing a timing slippage by constructing a single timing mechanism pressing a disk to a turn table by releasing the holding of a held disk. CONSTITUTION:A disk D is held on a moving plate 1, its pin 14 is engaged with grooves 11, 13 and the disk is carried inwards together with the driving plate 8 driven by a motor 18. When a pin 26 is transferred to an inclined part 12b from the horizontal part 12a of the groove, a linking plate 22 is converted to the center and a clamp member 20 abuts the center hole 29 of a disk opposing to a turn table. The movement of the moving member 1 is regulated with a louvering member 28 abutting to a regulating member 27, the pin 26 reaches the horizontal part 12c of the groove at the timing of the clamp member 20 abutting to a center hole 29, the movement of the linking plate 21 is stopped and the disk becomes rotatable. The disk can surely be clamped without causing any timing slippage on the transfer of the disk and the clamp operation onto the turn table.

Description

DETAILED DESCRIPTION OF THE INVENTION A) Field of Industrial Application The present invention relates to a disc loading device for transporting a disc to a loading/unloading position and a playback position.

(B) Prior art As a conventional disc loading device for transporting a disc to an loading/unloading position and a playback position, for example, Japanese Patent Laid-Open No. 58-45
Such a conventional device, for which the technique disclosed in Publication No. 656 (G11B17104) is probably well known, includes a conveyor for conveying a disk, a disk holding member disposed on the conveyor,
a clamp member that presses the disc against the turntable;
The player has a single drive unit that drives the transport body, and the disc inserted into the transport body from the insertion opening on the front surface of the player main body is held by the disc holding member, and the transport body is moved by the corresponding rear drive unit. This moves it to the playback position. At the same time, the disc holding member is activated to release the disc from holding the disc.

Further, the clamp member is moved toward the turntable to mount the disc on the turntable.

In such conventional devices, the disc is always transported in a horizontal state, and when the transport body is positioned at the playback position, the disc is placed on the turntable. Further, the clamp member is rotatably disposed above the conveyor, and is configured to be moved toward the turntable by its own weight under the control of a cam on the upper surface of the conveyor. Further, the disk holding member is actuated by the operating rod coming into contact with a wall in the direction of movement of the conveyor when the conveyor reaches the vicinity of the playback position.

In the conventional device described above, the disc can be transported and mounted to the playback position by a single drive unit, but since the clamp member moves toward the turntable due to its own weight, the player is placed vertically, that is, the disc is placed perpendicular to the ground. If the player is arranged so that the disc is inserted into the insertion slot, the clamp member is not activated and the disc cannot be mounted on the turntable.

Furthermore, in the prior art described above, it is conceivable to bias the clamp member in the direction of the turntable in order to operate the clamp member even when the player is arranged vertically, but in this case, in such a device, the disc holding member Since the clamping member and the clamping member are actuated by timing mechanisms on each side, it becomes difficult to control each member in a timely manner.

t/i Problems to be Solved by the Invention The present invention seeks to provide a disc loading device that can reliably load a disc onto a turntable even when the player is in a vertical position.

B) Means for Solving the Problems In order to provide a device as described above, the present invention provides a disc loading device for transporting a disc to a loading/unloading position and a playback position, including a moving member that moves in the transporting direction, and a moving member that moves in the transporting direction. a disc holding member disposed, a clamp member that presses the disc at the playback position against the turntable, and at the playback position, the disc is released from being held by the disc holding member and the clamp member is moved to the disc pressing position. The configuration has a single timing mechanism.

(e) Operation Since the disk holding member and the clamping member are driven and controlled by a single timing mechanism, there is no timing deviation, and the disk can always be reliably mounted on the turntable.

(f) Example Hereinafter, an example of the present invention will be described with reference to the drawings.

In Fig. 1, (1) is a movable plate, which is provided with a notch (2) from the front to the center, and has four levers (31 (31 (41)) with the rotation axis near the center.

At a predetermined movement position of the movable plate (1), it comes into contact with the cut-and-raise member (2) to restrict the movement of the movable plate (1).

The operation of this embodiment configured as above will be explained below.

In FIG. 1, the apparatus is positioned at the disk loading/unloading position, and the moving plate (1) and driving plate (8) protrude to a position where the notch (2) reaches the outside of the player. In addition, in this state, the lever (31 (roller (7) of 31) (71 is a spring (
Due to the bias of 51 (51), it is positioned at the bending part of V-shaped groove +l1l (1υ), and the lever (41 (roller of 41)
71(7) has a slope of 1t! t (131 (13)). Also, the clamp member (■) is located at a position away from the drive plate (8) due to the regulation of the pin (121 (121)) In this state, the disk (D) is brought into contact with the front rollers (7) + 7) and moved to the moving plate (1).
When the rollers (7) are inserted along the (7
) exceeds the diameter of the disk (D), the spring (51 (51
The lever (31 (31) is returned to its original position, and the disc (D) is sucked into the player (see Figure 3). Then, the front edge of the disc (D) is pressed against the rear roller (7) ( 7), the disk (D) is held by four rollers (71(7)(7)(7) (see FIG. 1)).

When the disk (D) is held on the moving plate (1) in this way,
When a switch (not shown) is opened, the drive motor is driven, thereby moving the drive plate (8) toward the inside of the player. At this time, the movable plate (1) has a pin circle α slope α4 (J4

Because it is locked to the drive plate (8) by engaging with the V-shaped TI/1 (11) (ll) and the inclined groove ■α3,
It is moved inward of the player along with the drive plate (8).

In this way, the disc (D) is carried into the player.

As the disk (D) is carried in as described above, the pin (■□□□) that is engaged with the clamp groove (2) U eventually becomes attached to the horizontal part (12a) (
12a) to the inclined portions (12b) (12b), and is biased toward the center, thereby causing the second connecting plate a2 (2
) shifts toward the center. In this way, the second connecting plate a
When 2a2 moves toward the center, the clamp member ■ moves toward the movable plate (1) as shown in FIG. come into contact with

When the clamp member ■ contacts the center hole (support) in this way, the cut-and-raise member (support) contacts the regulating member (5) at the same time to regulate the introduction of the moving member (1), and the disc ( D) is placed in this position. At this time, the disk (D) is in a position where its center hole is substantially directly opposed to the turntable (2).

However, even if the movement of the moving member (1) is restricted in this way, the drive motor tts+G! Not stopped, driving plate (8)
continues to be moved toward the inside of the player. That is, the clamp member (2) is continuously moved toward the disk and presses the upper surface of the disk (D).

On the other hand, when only the driving plate (8) is moved after regulating the movement of the moving plate (1), the V-shaped groove αυαυ and the inclined groove (13)
(Pin circle α41114 engaged with 131) (1Φ receives bias from these grooves and levers (3) (3) and (

Accordingly, the movement of the second connecting plate Q1)@ is stopped, and the displacement of the clamp member 2 is completed (FIG. 4 1al).

Then, the roller (71 (71 (7) (71) is further displaced, so that the inclined part (7a) (7a)

As mentioned above, the disc (D
) is rotated and played by the drive of the turntable (2), but when the disc (D) is taken out of the player, the procedure is reversed to the above.

That is, first, the drive motor .alpha. is rotated in the opposite direction to the above, and the drive plate (8) is moved toward the outside of the player. Next, as a result, the rollers (7) (7) (71 (7) are first displaced, the inclined portions (7a) (7a) (7a) (7a) come into contact with the periphery of the disk, and then the clamp member ■ is turned. The disc (D) separates from the table ■ and moves away from the turntable.Then, the disc (D) moves away from the roller (7) (

Since the center hole (support) of D) is located outside the player, the disk CD) can be taken out from the movable plate (1) by grasping and pulling the center hole @ and the peripheral edge with your fingers. At this time, since the operator can take out the disc (D) from the player without grasping the recording surface of the disc (D), fingerprints or the like will not adhere to the recording surface of the disc (D).

As described above, according to this embodiment, it is possible to reliably carry and mount a disc into a player with a simple configuration. Also,
By using the clamp mechanism having the first and second connecting plates, it is possible to reduce the size in the clamping direction.

(G) Effects of the Invention According to the disc loading device of the present invention, a single timing mechanism is configured to control the clamping operation of the disc onto the turntable and the operation of releasing the holding of the disc during disk transportation. Therefore, there is no timing difference between the respective operations, and the disc can be reliably mounted on the turntable.
