When the slider 105 is held in the housing 101, the side surface of the drawer 102 is pressed against the one side wall surface 101b of the housing 101 when the slider 105 is pressed by the wall surface 101a of the housing 101. Yes.
[0005]
[Problems to be solved by the invention]
However, in the conventional disk device described above, since the drawer carry-out mechanism and the drawer vibration prevention / suppression mechanism are provided separately, the number of parts is complicated and the mechanism is complicated, and the assembly of the disk device is reduced. There was a problem to do.
[0006]
An object of the present invention is to provide a disk device that solves such problems and has improved assemblability.
[0007]
[Means for Solving the Problems]
The present invention relates to a movable body on which at least a disk drive mechanism for mounting and driving a disk medium is mounted, a housing for storing the movable body in the disk medium during reproduction, and the movable body to and from the housing. Conveying means, pressing means provided on the movable body for pressing the movable body against a predetermined surface in the housing during reproduction of the disk medium, and a lock for holding and releasing the movable body in the housing A convex portion provided on a surface of the housing along the insertion direction of the movable body, and the pressing means provided on the movable body and orthogonal to the insertion direction of the movable body. When the slider is movable in the direction and the movable body is at the disk medium reproduction position in the housing, the slider engages with the convex portion and urges the slider to move the movable body. And a biasing member that presses against a surface of the casing along the insertion direction of the movable body and abuts the casing to generate a carry-out output in the carry-out direction of the movable body. .
[0008]
Specifically, when the movable body is at a disk medium reproduction position in the housing, the slider engages with the convex portion and one end urges the slider to insert the movable body of the housing. The first surface along the direction is pressed, the movable body is pressed against the second surface opposite to the first surface, and the other end abuts the housing to carry out the movable body in the unloading direction. And a torsion coil spring that generates force.
[0009]
That is, the disk device according to the present invention reduces the number of parts and simplifies the mechanism by combining a spring for carrying out the drawer and a spring for preventing and suppressing the vibration of the drawer with one spring. A slider for vibration / suppression of the drawer is disposed on the front portion of the drawer, and the torsion coil spring is configured such that the urging force is generated by the end of the torsion coil spring. Further, when the drawer is inserted into the casing, the end of the torsion coil spring is brought into contact with the bent portion of the casing to generate a force in the direction of carrying out the drawer. As a result, the two mechanisms for carrying out the drawer and preventing and suppressing the vibration of the drawer provided in the conventional disk device can be shared by one mechanism.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the overall configuration of a disk device representing an embodiment of the present invention. 2 (a) is a partially enlarged view for explaining the vibration preventing / suppressing mechanism and the drawer discharging mechanism of FIG. 1, and FIG. 2 (b) shows a part of FIG. 2 (a). The figure and the figure (c) are the figures seen from the side of the figure (b).
[0011]
Referring to FIG. 2 (a) to FIG. 2 (c) together, FIG. 1 (a) to FIG. The protruding guide 2a provided on both side surfaces of the drawer 2 and the guide support portion 3 provided in the housing 1, and the guide support portion 3 are slidably attached to connect the housing 1 and the drawer 2. Rail 4, lock mechanism 7 for holding and releasing rail 4 and drawer 2 in housing 1, solenoid 8 for driving lock mechanism 7, and conveying means for taking drawer 2 in and out of housing 1 (Not shown).
[0012]
Further, a slider 5 that can be advanced and retracted in the direction Xa-Xb orthogonal to the insertion direction of the drawer 2 is disposed at the front of the drawer 2, and this slider 5 is pressed in the Xb direction by the end 6 a of the torsion coil spring 6. It has been. Further, the end portion 6b of the torsion coil spring 6 protrudes below the drawer 2, and when the drawer 2 is inserted into the housing 1, the end portion 6b of the torsion coil spring 6 contacts the bent portion 1a of the housing 1, and the drawer 2 is carried out. It is arranged so that the force works in the direction to do.
[0013]
Next, the operation of this embodiment configured as described above will be described. The drawer 2 is manually inserted into the housing 1 and discharged by pushing a switch 2c disposed on the panel 2b of the drawer 2 to cause a current to flow through the solenoid 8 disposed in the housing 1, thereby locking the mechanism. This is done automatically by releasing 7.
[0014]
Next, a mechanism for preventing / suppressing vibration generated when a disk medium having an eccentric gravity center is driven when the drawer 2 is inserted into the casing 1 and a mechanism for discharging the drawer 2 from the casing 1 will be described.
[0015]
First, when the drawer 2 is inserted, the slider 5 is loosely moved in the Ya direction along the slope of the protrusion 1 a of the housing, and the drawer 2 is moved to the bent portion 1 b of the housing 1 by the reaction force of the torsion coil spring 6. Pressed. Thereby, it is possible to suppress the vibration in the direction perpendicular to the conveying direction of the drawer 2.
[0016]
Then, by inserting the drawer 2 into the housing 1, the end of the torsion coil spring 6 is pushed in the Ya direction from the bent portion 1c of the housing 1, and the reaction force in the Ya direction acts on the drawer 2. This reaction force becomes a force for carrying out the drawer 2.
[0017]
【The invention's effect】
As described above, the disk device of the present invention has an effect that the number of parts can be reduced and the mechanism is simplified, so that the assemblability is improved. Further, since the drawer vibration prevention / suppression mechanism and the tray carry-out mechanism are integrated, there is an effect that an occupied space on mounting is reduced and an effective space for other parts is increased.
