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

0002

2. Description of the Related Art FIGS. 4A to 4C are explanatory diagrams of the operation of a conventional optical disk drive device. (a) shows the state before the cartridge C containing the optical disk is inserted, (b) shows the cartridge C in the middle of insertion, and (c)
indicates a state in which the carriage of the cartridge C has been completed and loading has been completed.

[0003] The front panel 1 is provided with an insertion opening 1a,
A rotary shutter 2 is supported inside the insertion opening 1a so as to be rotatable about its upper end, and is biased by a spring 3 in the direction of closing. Cartridge C inserted from the front inside
A substantially box-shaped holder 4 that holds the cam from above connects the cam groove 6 of the slide cam 6 via guide rollers 5 provided on its side.
It is supported by a. The holder 4 is movable only in the vertical direction by a mechanism not shown, and the slide cam 6 is movable only in the front and back directions and is attached to the front panel 1 by a spring not shown.
However, in the state shown in (a), it is locked at the rear by a mechanism not shown.

When inserting the cartridge C, the rotary shutter 2 is urged by the cartridge C and rotates backwards as shown in (b). Then, when the cartridge C is pushed in further, the lock is released and the slide cam 6 is released. It moves forward and urges the holder 4 downward via the cam groove 6a. When the cartridge C is completely inserted, the holder 4 descends and reaches the operating position as shown in (c).

[0005]

However, with such a configuration, the insertion port 1a remains open during operation as shown in FIG. 4(c), making it impossible to prevent dust from entering. To solve this problem, it has been proposed to close the insertion port 1a with another shutter when loading is completed. However, since the shutter 2 is raised and lowered by a lever that rotates in a plane that includes the cartridge insertion direction and is perpendicular to the disk surface, the base and electrical board cannot be placed within the rotation range of the lever, resulting in inefficient space allocation. There are problems such as it becomes a target and the strength of the base is insufficient.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a compact optical disk drive device that does not allow dust to enter upon completion of loading.

[0007]

[Means for Solving the Problems] An optical disc drive device according to the present invention for achieving the above-mentioned object includes a holder for transporting a disc cartridge inserted from an insertion slot to an operating position, and a holder for transporting a disc cartridge inserted from an insertion slot, and a The optical disc drive device includes a shutter that closes the insertion slot, and the optical disc drive device includes a lever that rotates in a plane perpendicular to the insertion direction of the disc cartridge, and the lever closes the shutter in conjunction with the transport operation of the holder. The device is characterized in that it is configured to be driven.

[0008]

[Operation] In the optical disc drive device having the above configuration, when a disc cartridge is inserted through the insertion slot, the lever rotates in conjunction with the holder that moves in the transport direction of the disc cartridge, moves the shutter, and closes the insertion slot. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 3. Note that the same reference numerals as in FIG. 4 indicate the same members.

FIGS. 1 and 2 are perspective views of a loading mechanism and a shutter of an optical disk drive device. An insertion slot 11a is provided slightly above the center of the front panel 11, and a slide shutter is provided inside the front panel 11. 12 are in contact. FIG. 1 shows a state in which the slide shutter 12 is lowered, and a rotary shutter 2 (not shown) is supported inside the front panel 11 so as to be rotatable around the upper end, and the insertion opening 1
1a is occluded. Further, on both sides of the inner lower part of the front panel 11, a lever 13 is provided, which is rotatably supported approximately at the center by an unillustrated shaft parallel to the cartridge insertion direction, and an outer arm of the lever 13 is provided. A rearwardly projecting pin 13a is formed at the tip of the lever 13.
A linear spring 14 is attached to the inner tip of the spring 14 toward the center. At the rear of the front panel 11, a substantially box-shaped holder 15 is supported by the cam groove 6a of the slide cam 6 via guide rollers 5 on the left and right side surfaces, and the front end of the plate-shaped portion forming the lower surface of the holder 15 is bent downward to form bent part 1
5a is formed, and a pin 13a of the lever 13 is fitted into a horizontally formed notch 15b of this bent portion 15a. The slide shutter 12 is supported at the tip of the linear spring 14, and the holder 15 is movable only up and down, and the holder 15 and the slide shutter 12 are configured to interlock in opposite directions in the up and down directions via the lever 13.

FIG. 2 shows a state in which the loading of the cartridge C is completed. As the slide cam 6 advances, the holder 15 descends, the lever 13 rotates, and the slide shutter 12 rises, opening the insertion opening 11a. Indicates a closed state.

FIGS. 3(a) to 3(c) are explanatory views of the operation seen from the side, and FIG. 3(a) shows the state before the cartridge C is inserted. The opening 11a is closed, (b) shows a state in which the cartridge C is inserted and the rotary shutter 2 is pushed open by the cartridge C, and (c) shows a state in which the loading of the cartridge C is completed. ing. In addition, in this FIG. 3, the lever 13 and the linear spring 1
4 is omitted from illustration.

When the cartridge C is inserted through the insertion port 11a, the rotary shutter 2 is in a rotated state as shown in FIG. When the cartridge C is placed inside, the holder 15 is lowered. In this state, the rotary shutter 2 is open, but the slide shutter 12 is raised to close the insertion port 11a as shown in FIG.

[0014] By doing this, the rotary shutter 2 closes the insertion slot 1 until the cartridge C is loaded.
1a is closed and after loading, the rotating shutter 2
Slide shutter 12
Since the insertion port 11a is closed by the insertion port 11a, it is possible to prevent dust from entering through the insertion port 11a.

In such a configuration, when the operator pushes in the cartridge C with his/her finger, it is conceivable that the finger will be caught between the slide shutter 12 and the insertion opening 11a, but the interlocking between the holder 15 and the slide shutter 12 is linear. Since this is done via the spring 14, even if the linear spring 14 bends, no load beyond a predetermined level will be applied to the finger, thereby preventing injury to the finger.

In the embodiment, the lever 13 is driven to rotate directly by the holder 15, but the lever 13 is driven to rotate indirectly by, for example, bringing the lever 13 into contact with the cartridge C that moves together with the holder 15. It can also be used as a thing.

As explained above, the optical disc drive device according to the present invention closes the insertion opening with the slide shutter in conjunction with the conveyance of the disc cartridge while the disc cartridge is being inserted, so that even when the disc cartridge is loaded, there is no problem in the device. Since the lever that drives the slide shutter rotates in a plane perpendicular to the insertion direction, the shutter lifting mechanism can be concentrated near the insertion opening, and the entire device can be made smaller.
