Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk drive device having a shutter for preventing dust from entering an insertion hole of a disk cartridge.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view of a loading mechanism section and a shutter section of an optical disk drive apparatus, in which an insertion hole 1a is provided in the center of a front panel 1, and a slide shutter 2 is provided inside the front panel 1. Are in contact with. FIG. 4 shows a state in which the slide shutter 2 is lowered, and a substantially central portion is rotatably supported on both sides of the inner lower portion of the front panel 1 by a shaft (not shown) parallel to the cartridge insertion direction. A lever 3 is provided, and a pin 3 protruding rearward is provided at a tip of an arm outside the lever 3.
a is formed, and the linear spring 4 is attached to the inner tip of the lever 3 toward the center.

On the rear side of the front panel 1, a substantially box-shaped holder 5 is supported by a cam groove 7a of a slide cam 7 via guide rollers 6 on the left and right side surfaces, and a plate-like member constituting the lower surface of the holder 5 is supported. The front end of the bent portion is bent downward to form a bent portion 5a, and the notch 5 formed horizontally in the bent portion 5a.
The pin 3a of the lever 3 is fitted in b. Linear spring 4
The slide shutter 2 is supported at the tip of the holder, and the holder 5
Is movable only up and down, and the holder 5 and the slide shutter 2 are configured to move in the opposite vertical directions via the lever 3.

FIGS. 5 (a) to 5 (c) are explanatory views of the operation seen from the side. FIG. 5 (a) shows a state in which the cartridge C is inserted with a finger F, and FIG. 5 (b) shows a state immediately before the holder 5 descends. Cartridge C
And (c) shows a state in which the loading of the cartridge C is completed. In addition, in FIG. 5, the illustration of the lever 3 and the linear spring 4 is omitted. When the cartridge C is inserted through the insertion hole 1a, the lock of a spring (not shown) is released and the slide cam 7 is biased forward,
When the cartridge C enters the inside, the holder 5 descends. In this state, the rotary shutter 2 is open, but the slide shutter 2 rises to close the insertion hole 1a as shown in (c).

In such a structure, when the operator pushes the cartridge C with the finger F, the finger F may be sandwiched between the slide shutter 2 and the insertion hole 1a. However, the holder 5 and the slide shutter 2 are interlocked. Since it is performed via the linear spring 4, even if the linear spring 4 bends, a force larger than a predetermined force is applied to the finger F.
And does not injure the finger F.

[0006]

However, in the above-mentioned conventional example, in order to avoid the interference between the cartridge C and the shutter 2, it is necessary to insert the cartridge C into the deep portion of the apparatus with the finger F and load it. Since the width W of the insertion hole 1a in the height direction is as narrow as 10 mm or less, when the cartridge C is inserted, the finger F hits the front panel 1 and the operation feeling is bad. Moreover, if the width W of the insertion hole 1a is increased, the width of the shutter 2 must also be increased, which results in hindering the thinning of the drive device.

It is an object of the present invention to provide an optical disk drive device that prevents dust from entering and thickens the drive device at the time of completion of loading, and has a good feeling of loading operation.

[0008]

In order to achieve the above object, an optical disk drive device according to the present invention is an optical disk having a shutter that closes an insertion hole provided in a front panel into which a cartridge is inserted after the cartridge is inserted. The drive device is characterized in that a movable part which is retracted by a pressing force and is restored by releasing the pressing force is provided at an upper part or a lower part of the insertion hole.

[0009]

In the optical disk drive device having the above-described structure, when the operator's finger abuts on the movable portion, the cartridge and the movable portion are pressed inside as the cartridge is inserted. When the insertion of the cartridge is completed and the operator returns his / her finger, the movable part returns to the original position, the shutter closes the insertion hole, and the inside of the device is sealed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a perspective view of the optical disk drive device, and the loading mechanism for moving the cartridge C up and down is the same as that of the conventional example, so the same reference numerals are given and the description thereof is omitted. A front panel 12 having a rectangular insertion hole 11 that is long in the horizontal direction is provided on the front surface of the box-type optical disk drive device. The front panel 12 is provided with a recess 13 that is open to the front in the upper center thereof. Inside the recess 13, two shafts 15 that are surrounded by a compression coil spring 14 and that are long in the insertion direction of the cartridge C are provided. A slide member 14 which is provided on the rear side and is locked to the front panel 12 by a step end surface 16 on the front portion is press-supported so as to be slidable in the insertion direction.
The front surface of 2 and the front surface of the slide member 17 are parallel to each other.

At the time of loading, as shown in FIG. 2 (a), the operator inserts the cartridge C into the optical disk device through the insertion hole 11. The cartridge C is inserted deeply into the device by the finger F, but the finger F moves the slide member 17
When it comes into contact with the compression coil spring 1 as shown in Fig. 2 (b).
4 is compressed, and the slide member 17 retracts according to the position of the finger F. When the operator retracts the finger F after the lock of the slide cam 7 is released, the cartridge C descends and is placed at a predetermined position, the compression coil spring 14 is restored,
The slide member 17 returns to the original position, and the slide shutter 2 rises to close the insertion hole 11 as shown in FIG. 2 (c). In this way, although the width W of the insertion hole 11 in the height direction is not expanded, the slide member 17 retracts to give the fingertip a feeling of strangeness as if the width W of the insertion hole 11 has expanded. The loading operation feeling is improved.

FIG. 3 is a perspective view of an optical disk device using another embodiment. In this embodiment, in the concave portion 13, instead of the slide member 17, a revolving door 18a that opens inwardly is provided.
18b is provided. The revolving doors 18a and 18b are urged by a torsion spring (not shown) so as to be flush with each other in the state where no pressing force is applied.

At the time of loading the cartridge C, the operator's finger abuts the revolving doors 18a and 18b when the cartridge C is inserted, as in the above-described embodiment, and the revolving door 18
Cartridge C is smoothly loaded by rotating a and 18b.

In the above embodiment, the recess 13
Although the above is provided on the upper part of the front panel 12, the same effect can be obtained even if the slide shutter 2 is provided on the lower part and the slide shutter 2 descends from the upper part.

[0015]

As described above, in the optical disk drive device according to the present invention, the height of the insertion hole is increased by providing a movable portion against the pressing of the fingertip at the upper part or the lower part of the cartridge insertion hole of the front panel. The operation feeling at the time of loading can be improved without increasing the width in the direction.
