Description

[Detailed Description of the Invention] [Technical Field] The present invention is an opening/closing lid device that is capable of opening and closing a tray opening and closing opening formed on the front panel of a compact disc player in conjunction with the movement of a tray. It is related to.

[Prior art]

Conventionally, a roller for transporting a tray on which a compact disk is mounted in a compact disk player,
Since the opening/closing lid that opens and closes the tray entrance/exit opening in the front panel has only an independent function, only the effects of each can be expected. In particular, with regard to the opening/closing lid, the opening and closing of the tray entrance/retreat was done by contacting the front end of the tray and moving the tray, which caused damage to the area where the opening/closing lid came into contact with the tray. It was causing a problem.

[Purpose of the invention] The present invention provides an opening/closing lid that does not damage the opening/closing lid, and that presses the tray with a roller and opens and closes the tray advance/retreat opening with the opening/closing lid in one action in response to the movement of the tray. The purpose is to provide equipment.

[Summary of the idea]

In order to achieve the above object, the opening/closing lid device of the present invention includes a roller that rolls while pressing the tray of a compact disc player while the tray is being transferred, a roller arm that holds this roller, and a roller arm that holds the roller. It consists of a lid that is integrally connected to the roller arm and opens and closes the tray advance/retreat opening formed on the front panel of the compact disc player.The connection between the opening/closing lid and the roller arm is rotated from the front panel side. The roller arm is movably supported and resiliently biased toward the bottom of the compact disc player. Depending on the state of transport of the tray, the operation of the rollers to press the tray to prevent the tray from rattling and the opening and closing of the tray advance/retreat opening by the opening/closing lid can be performed in one action in conjunction with each other.

[Example of idea]

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. A case 1 of the compact disc player includes a clamp mechanism (not shown) and a compact disc player main body 2 built therein. This compact disc player body 2
and the clamp mechanism section are arranged in a facing relationship. A front panel 3 of the case 1 is formed with an opening 5 (hereinafter abbreviated as opening 5) for advancing and retracting a tray 4 for mounting a compact disk (not shown). Stepped locking portions 5a and 5b for locking a lid 11, which will be described later, are formed at the upper and lower portions of the opening 5. The tray 4 moves forward and backward through the opening 5, and can be moved parallel to the compact disc player main body 2 side and to the side away from the compact disc player main body 2. In order to smoothly and reliably move the tray 4 in parallel to the compact disc player main body 2 side,
Guide pins 6 and 7 are protruded from both sides of the tray 4, and guide holes 9 and 10 are provided in parallel in the side chassis 8 in order to guide the guide pins 6 and 7 and move the tray 4 to a predetermined position. It is formed by

The opening 5 of the front panel section 3 has this opening 5.
A lid 11 for closing and opening is attached. Step portions 11a and 11b are formed at the upper and lower ends of the lid 11, and are adapted to engage with locking portions 5a and 5b of the opening 5, respectively. On the other hand, a roller 12 that presses the tray 4 while the tray 4 is being transferred is in rolling contact with the upper surface of the tray 4, and is held by a roller arm 14 via a shaft 13. Roller arm 1
4 and the lid 11 are integrally connected, and the connecting portion 1
5 has a boss 16 protruding from it. Boss 16 is
It is held by a boss holder 17 provided on the front panel 3 side, and connects the integrally connected roller arm 14 and lid 11 at their connecting portion 15 as shown by arrow A.
- It is rotatably supported in the B direction. Note that the angle of connection between the roller arm 14 and the lid 11 is
is set so that it does not come into contact with the lower surface of the transferred tray 4 when it is opened from the opening 5 to the maximum extent. Also, on the roller arm 14 near the roller 12, there is a bottom side 18 of the compact disc player.
A tension spring 19 is tensioned from the roller arm 14 and urges the roller arm 14 toward the bottom side 18 of the compact disc player body 2.

Next, the operation of the tray 4 and the lid 11 will be explained.

Tray 4 is the compact disc player body 2
When in the upper position, the guide pins 6 and 7 are in the guide hole 9,
10 and the roller 12 is positioned on the front end of the tray 4 under the tension of a tension spring 19. The lid 11 is in a state in which the opening 5 is closed. The tray 4 is the guide pin 6,
When the tray 4 begins to move along the guide holes 9 and 10 via the tray 7, the front end of the tray 4 comes into contact with the roller 12, enters under the roller 12, and begins to push the roller 12 up in the direction of arrow B. At this time, the tension spring 19 begins to extend against the tension force. As the roller 12 moves in the direction B due to the pushing up of the tray 4, the roller arm 14 rotates around the boss 16, and at the same time, the lid 11, which is integrally connected to the roller arm 14, also rotates around the boss 16 in the direction of arrow B. The opening 5 is opened by rotating in the direction. The upward movement of the tray 4 is caused by guide pins 6 and 7, as shown by solid lines in the figure.
is carried out until it is guided by the straight portions of the guide holes 9 and 10. At this time, the pressure on the tray 4 by the roller 12 is further strengthened by the tensioning action of the tension spring 19, and the lid 11 is pressed against the tray 4 by the roller arm 14.
It has completely rotated to position B in synchronization with the rotation of .

Next, the tray 4 is guided by the straight portions of the guide holes 9 and 10 and retreats through the opening 5 and out of the opening 5 while being pressed by the rollers 12.
will no longer be pushed up by the tray 4 and will not move while being pressed on the tray 4. Therefore, the lid 11, which is integrated with the roller arm 14, remains stopped at the B position. Then, when the tray 4 is retreated to a predetermined position, the tray 4 stops.

When the tray 4 enters the compact disc player main body 2 side along the straight line of the guide holes 9 and 10 from the retreated position of the tray 4, the above-mentioned tray As in the case of retraction, the roller 12 simply presses onto the tray 4 and rolls due to the tensile force of the tension spring 19, and the lid 11 remains completely open. The guide pins 6 and 7 of the tray 4 enter the curved portions of the guide holes 9 and 10, and when the tray 4 is guided by the curved portions of the guide holes 9 and 10 and descends toward the compact disc player main body 2, the guide pins 6 and 7 enter the guide holes 9 and 10. The roller 12 moves in the direction of arrow A while pressing the tray 4 under the action of the tensile force of the tension spring 19. The roller arm 14 also rotates in accordance with the movement of the roller 12, and the roller arm 1
4, the lid 11 also rotates around the boss 16 in the direction of arrow A and approaches the opening 5. Furthermore, lid 1
1 rotates due to the downward movement of the tray 4 and the tensile force of the tension spring 19 of the roller arm 14, and the stepped portions 11a and 11b of the lid 11 engage the locking portions 5a and 5b of the opening 5.
come into contact with. Then, the tray 4 is inserted into the guide holes 9 and 1.
When the disc is guided to the end of the compact disc and set on the compact disc main body 2, the roller arm 14 is pulled by the tension spring 19 and the lid 11 completely closes the opening 5.

[Effect of idea]

As explained above, when using the opening/closing lid device of the present invention, the roller and the lid are integrally connected and interlocked, so that the pressing of the tray by the roller and the opening/closing of the tray advance/retreat opening by the lid are controlled. It can be done in one go. Furthermore, since the lid is opened and closed with a distance between the lid and the front end of the tray as the tray advances and retreats, there is no contact between the tray and the lid, and therefore no damage is caused to the lid.
