Abstract

PURPOSE:To obtain a simple door switching mechanism by using moving force of a disc to open/close the door. CONSTITUTION:In loading a disc 1 from an open hole 2a of a panel 2, the tip of the disc 1 is abutted on the door 10 to push up the door 10, and the door 10 is turned above the inside of the player against the spring 11. Thus, a pin 10a slides in a slot 14a of a connecting plate 14, which is moved upward attended therewith. Since a couple of sots 14c, 14d are engaged with a couple of projections 13c in the connecting plate 14, the plate 14 is not turned but moved in parallel, the pin 12a of the door 12 is slides in the slot 14b and is turned in a direction opposed to the door 10 similarly so as to attain loading of the disc 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a door opening/closing mechanism used in a disc player or the like.

[Conventional technology]

Figure 6 shows a door opening/closing mechanism used in a conventional audio disc player. In the figure, (1) indicates a disc, and (2) indicates an opening (2a
) is formed on the front spring /L/% (3) is the spring A/ (
2) Opening (2a) A door rotatably arranged at the rear, (
4) is a link mechanism that rotates this door (3), and is driven by a solenoid (5). Also, (6) is the door (3
), and the lever (6) is configured to operate the control circuit (7) and drive the 1 solenoid (6).

With this configuration, when the disk (1) is brought into contact with the door (3) and pushed in, the door (3) will rotate around the fulcrum (8a), and along with this, the door (3) will rotate around the fulcrum (8a). The lever (6) moves and drives the switch in the control circuit (7) to energize the solenoid (5). Therefore, as shown in Fig. 7, the link mechanism (4) is driven and the door (3) is opened wide.Next, the disc (1) is set in the player and the device is in the operating state. Then, the current in the solenoid (5) is cut off and the door (3) closes the aperture (2a). Furthermore, when the ejection switch for the disk (1) is operated, the solenoid (5) is energized via the control circuit (7), the door (3) is maintained in the open state, and the disk (1) is ejected. Then, the door (3) is closed and the initial state is restored.

[Problem that the invention seeks to solve]

Such a conventional door opening/closing mechanism requires one solenoid (5) and a control circuit (7) to open and close the door (3), resulting in problems such as complicated control.

This invention was made to solve the above-mentioned problems, and it provides an opening/closing mechanism that opens and closes the door by the force of inserting and removing a disk, etc., and is particularly aimed at preventing damage to the disk. be. [Means for solving the problem] The door opening/closing mechanism according to the present invention includes a pair of doors disposed opposite to each other in the insertion direction, a connecting plate for interlocking these doors, and a disc in the door. The end of this contact portion is configured to be an inclined surface.

[Effect]

The door opening/closing mechanism in this invention rotates the other door by the rotational force of the door in contact with the Dinuk when inserting or removing the disk, and also brings the door into contact with the outer periphery of the disk using the inclined surface, thereby preventing damage to the information recording section. becomes possible.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG. In Fig. 1, 1αO is the spring/1/ (2) opening (2a
) is placed opposite the door and is rotatably supported toward the inside of the player.
The spring (6) that biases the side is placed behind the door Q13, and the door is supported so that it can rotate in 10 directions, and each door QO (2) has a pin ( 10a) (12
an inclined surface (10b) to which a) is attached and whose length gradually decreases toward a portion corresponding to the central portion of the opening (2a);
(12b) is formed. In addition, a large notch (12c) is formed in a portion of the door (2) that corresponds to the center of the opening (2a), and the end of this notch (12c) and the inclined surface (12b) are connected to the inclined surface. (12d) so as to be continuous. Furthermore, the width of the door (2) is smaller than the door αG. A is these doors αG
A support plate that supports (2) holds the spindle of the door αO@ at a predetermined distance, and also holds the pins (10a) (12a,
) and a pair of protrusions disposed between the grooves (18a) (18b).
18c) (one not shown) is formed. Q4
is a connecting plate that interlocks JilQO (b), and has a pair of @ (t4aX14b) formed in the horizontal direction and a pair of grooves (14C) (14d) formed in the vertical direction, and a pair of grooves ( 14c) (14d) has a support plate (
(to) protrusion (18c) Z>f, pair of grooves (14a)
(14b) K door α1@ pin (10a) (12a
) are inserted and each is movably supported. (g) is fitted into the protrusion (18c) to connect the connecting plate α.
This is an E-ring that prevents the thigh from falling out.

Under such a configuration, disk (1) is attached to panel (2).
), the tip of the Dinuk (1) will come into contact with the door Ql) and push up the door αG, and the door QQ will rotate upwards inside the player against the spring (b). It will move. Therefore, as shown in FIGS. 2 and 8, the pin (10a) is attached to the connecting plate (14(7)).
The connecting plate a4 slides in the groove (14a) and is accordingly moved upward. At this time, the connecting plate (b) has a pair of protrusions (18c) and a pair of grooves (44cX14d).
) are engaged, so the pin (12a) of Ji (2) moves in parallel without rotating, and the pin (12a) of Ji (2) is engaged with the groove (1
4b) The disc (1) can be slid inside and rotated in the opposite direction in the same way as the Haa, allowing the insertion of the disc (1).Next, the disc (1) is inserted inside the player and the door @ this When the abutment is released, the door GO (to) springs (b)
Pins (10a) (10b) are pulled back by the urging force of (connection play) 04 grooves (14a) (14b).
slips and the connecting plate α4 also descends, returning to its initial state.

After that, when ejecting the disc (1),
) ejection mechanism causes the disk (1) to release the spring /I/ (
When it is transferred to the 21 side, first, there is a disc (1) on the door).
The tip of the door (2a) will come into contact with the door (2a), and the door (2a) will be pushed up toward the opening (2a), and the door (QO) will be rotated via the pin (12a), the connecting plate α4, and the pin (10a) in the same way as above. ,
The aperture (2a) of the spring /L/ (2) can be opened to allow ejection of the disc (1).

By the way, in a device that opens and closes the door (to the IG) by contact between the disc (1) and the nasal tip (b), the door α0
The free end side of (6) will rub against the information recording portion of the disk (1), possibly damaging the recorded information. By making the free end side of the door αG (2) an inclined surface, the door QOU can be adjusted according to the insertion position as shown in Fig. 4 and Fig. 5.
o Inclined surfaces (10b) (10C) The outer circumferential end surface of the disk (1) will slide, and at this time, the intermediate part of the disk (1), that is, the recording section, will face the concave part of the door QO (2) and move toward the door αO ( There will be no direct contact with (to). Therefore, the fear of damaging recorded information can be eliminated.

Although the disc (1) is shown to be moving in Figures 4 and 5, in reality the disc (1) moves on the same horizontal plane and the door αG (2) moves upward. It is.

〔Effect of the invention〕

As explained above, according to the present invention, the door can be opened and closed by the moving force of the disk, and it is possible to obtain a simple door opening and closing mechanism and to prevent damage to the disk during insertion. .
