Abstract

PURPOSE:To simplify the constitution of the titled holder by constituting the holder so that a rotary lever is made come abutting on the front end of a carrier body by moving the carrier body itself to turn the turning lever, and making a pressing pin contact the arm part of a disk holder to turn the disk holder in such a direction as coming off an energizing means against its force. CONSTITUTION:When an external chassis 16 is made to move by the rotation of a drive gear 43, an internal chassis 17 is made descend by the actions of a vertical groove 10 provided along the side of a stopper 9 and an external chassis 16, accordingly, a disk D is placed on a turn table 2a, and at the same time, a clamping lever 12 that has been regulated by the top surface of the internal chassis 17 is turned to make a clamping member 13 descend. As the external chassis 16 further moves, its front side part presses the end part of a turning lever 8 and turns the lever 8 counterclockwise. As a result, the pressing pin 7 of the lever 8 presses the arm parts 34, 35 of disk holders 18, 19 against energizing, so that the disk holders 18, 19 turn to release the holding of the disk D.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a disc holding device provided for holding a disc on a carrier while the disc is being slowly moved into a player.

(B) Conventional technology Conventionally, as a holding device for holding a disc, for example, Japanese Patent Application Laid-Open No. 60-80160 (CIIB 17104)
The technique disclosed in . In such conventional technology, as a holding means for holding the disk, a recess is provided on the upper surface of the horizontally arranged slow moving body, and the disk is stored and placed in the recess to hold the disk against the carrier. .

However, with the above-mentioned conventional technology, if external vibration is applied to the player during the recording and transfer of the disc, there is a risk that the disc will pop out of the recess, which makes it difficult to apply it, for example, when the player is used in a car. Ta.

On the other hand, CDF-600 manufactured by Sanyo Electric Co., Ltd.
Two rotation pins and one rotation lever are pivotally supported on the transport body, and the edge of the disk is clamped by biasing these. That is, when the disc is installed, the carrier is positioned near the insertion hole for inserting the disc, and when the disc is inserted through the insertion hole, the two rotating bins abut against the edge of the disc and expand against the bias. When the disc is opened and a further disc is inserted and the position of the two pivot pins exceeds the center of the disc, the bias causes the pivot pin to pivot, thereby pressing the edge of the disc. The disc is then carried into the player, and at a predetermined insertion position, the front end of the disc comes into contact with one end of the rotating lever, so that the disc is held between three points by the rotating pin and the rotating lever.

In this type of conventional technology, since the disk is held between its edges, it will not be displaced from the carrier even if vibration is applied to the player as described above, and therefore it can be applied even when the player is used in a vehicle. It is. However, in the case of such a device, since the movable bin and the rotating lever must always be positioned inside the player, the amount of protrusion of the disc from the insertion hole is small when the disc is ejected, and the recording of the disc is not possible when the disc is ejected. This has the disadvantage that the surface must be grasped, and fingerprints and the like may adhere to the recording surface.

(c) Problems to be Solved by the Invention The present invention aims to realize a disk holding device with a simple configuration that can securely hold a disk during transportation and increase the amount of protrusion of the disk when unloading the disk. It is something to do.

(d) Means for Solving the Problems In view of the above points, the present invention provides a transport body slidably disposed on a fixed chassis, and a pair of disks rotatably supported by the transport body. The holder, the grooves arranged along the opposing sides of each disc holder, the arm part also arranged on the disc holder, and the rotating end of the disc holder are biased in a direction toward each other. a rotating lever rotatably supported by the fixed chassis; and a pressing pin implanted at one end of the rotating lever; The end of the rotary lever is brought into contact with the front end of the body, and by rotating the rotary lever, the pressing pin is brought into contact with the arm portion of the disc holder. It is configured to be able to rotate in a direction away from each other against the urging force of the urging means.

(E) When the working disk is pressed and inserted along the cut groove of the disk holder, the disk holder is spread open by the edge of the disk against the force, and the force of the force caused by such expansion causes the disk to open. It is held in the disc holder. Then, when the transport body moves into the player and the disc is positioned on the turntable, the rotary lever pivoted on the fixed chassis is rotated by the transport body, so that the disc holder resists the force. The disc is expanded and separated from the edge of the disc, and the disc is no longer held.

This will be explained with reference to FIGS.

35th! J is a diagram showing the time when loading is started.

The disc holder (1g) (19) is attached to the front panel (
The disc (not shown) protrudes from an insertion hole (not shown) provided in the disc (not shown), and the disc ( D) into the insertion hole. At this time, since the disk holders (18 and 19) are biased toward each other by the springs (33), their rotational ends are smaller than the diameter of the disk (D), but as described above, disk < D. ) into the insertion slot, the disk holder (1B>(19)) is pushed open by the edge of the disk (D), thereby the disk (D) is held between its edges and placed in the disk holder (18) (19). ) is held. At this time, the cut and raised piece (53) of the clamp lever (12) is in contact with the top surface of the external chassis (16) of the carrier (15), so the clamp member (13) is in the lifted position and in the non-clamped position. )
It is positioned in When the disk (D) is held in the disk holder (18) (19) in this way, this is detected by a detection switch (not shown), and the motor (41
) is fully rotated and the drive gear (43) can be fully rotated counterclockwise. Since the drive gear (43) itself is meshed with the first rack (6) of the fixed chassis (1), it moves in the direction of arrow B, and on the other hand, the transport body (15)
A second rack (25) located on the external chassis (16) of
), the outer chassis (16) is sent in the direction of arrow B. When the external chassis (16) is sent in the direction of arrow B in this way, the internal chassis (17) is also connected to the external chassis (16) by the spring (27), so it moves along with the external chassis (17). Move in direction B.

As the disk (D) was transported into the player in this manner, when the center hole of the disk (D) reached just above the turntable (2nd), it protruded from the internal chassis (17). Of the pins (26) (26) (26) (26),
One of the bins located in the front (26 on the fixed chassis (1
), and further movement of the internal chassis (17) is restricted (see Figure 4). At this time, the clamp lever (12) has its protrusion (14) contacting the internal chassis ( 17), so it is still in the non-clamped position.

Thereafter, when the external chassis (16) continues to move due to the rotation of the drive gear (43), the locking piece (9)
Vertical grooves (10) provided along the sides of and guide holes (20) in the external chassis (16)
The inner chassis (17) is lowered by the action of ) is rotating? pump parts (
13) descends. And then further external chassis (
16〉 moves, the front side of the external chassis (16) presses the end of the rotary lever 8〉, causing the rotary lever (8) to rotate in the counterclockwise direction. The pressing pin (7) presses the arms (34) (35) of the disc holders (18) (19) against the bias, and rotates the disc holders (18) (19) in a direction to separate them from each other. Then, release the holding of the disk (D>) (see Fig. 5).

Through the above operations, the disc (D) is placed on the turntable (2a) and the clamp member (13) is placed on the turntable (2a).
The disc holders (18) and (19) are further separated from the edge of the disc (D), thereby enabling rotational drive by the turntable. In this way, the installation of the disk (D) is completed.

When discharging the disk (D), the above procedure is reversed. That is, when the motor (41) is rotationally driven in the opposite direction to the above, the external chassis (16) is moved in the direction of arrow C, and accordingly, the rotation lever (8) is first rotated clockwise. Then, the disk holders (18)<19) approach each other and clamp the edges of the disk (D). And after that, the vertical groove (10) and the guide hole (20) (20) (2
0) (20) sloped part (20b) (20b) (20b)
(20b) causes the internal chassis (17) to rise, and together with this, the protrusion (14)
The clamp lever (12) is pressed upward by the top surface.
is rotated, and the clamp member (13) is separated from the upper surface of the disk (D). Then, the bins (26) (26) (26) (26) of the internal chassis (17) are connected to the guide holes (20) (
20) (20) When positioned at the upper end of (20),
Thereafter, as the outer chassis (16) moves, the inner chassis (17) moves in the direction of arrow C, and the disk (D) is brought out of the player through the insertion hole. In this way, the disc (D) is transported outside the player, and it becomes possible to attach and detach the disc.

(G) Effects of the Invention According to the present invention, since the disk is reliably held by the disk holder even at low speeds,
Even if the player is subjected to external vibrations, it will not be displaced from the conveyor, and since a pair of disc holders are used as holding members, it is not possible to protrude such a disc holder from the insertion hole in the conventional technology. , the amount of protrusion of the disk can be increased. Further, since the disc holding device is composed of a pair of disc holders and a rotating lever, and the opening and closing of the disc holder is controlled by the movement of the carrier, the number of parts is small and the construction is extremely simple.
