Abstract

PURPOSE:To prevent the laser light from leaking from an opening part by inhibiting opening of a cover when a disk and a disk plate are set to a recording and reproducing position. CONSTITUTION:A containing case 13 provided in a device body 1 moves up and down in the device body 1 in a state that it contains and holds a disk plate 9. In a position where the containing case 13 has descended, a shaft of a disk motor 14 is fitted into a center hole of a disk 3, and the disk 3 is rotated by its rotational force. At the same time, a laser light is outputted from the tip of a pickup 15, irradiated to the disk 3 and executes a recording or reproducing operation of a signal to the disk 3. A projecting piece 16 is provided on the left and right end parts of the tip of the containing case 13, and a stopper piece 5 provided on a cover 4 is formed in accordance with this projecting piece 16. When the containing case 13 is made to descend and in a recording or reproducing state, the end face of the projecting piece 16 contacts by pressing to the stopper piece 5 or it is opposed very adjacently, therefore, even if it is tried to open the cover 4 in this state, the cover 4 does not turn and does not open since the stopper piece 5 collides with the projecting piece 16. Accordingly, it is not feared at all that a laser light leaks from an opening part 2 in a recording or reproducing state.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is directed to optically recording signals on a disc-shaped recording medium and optically reading signals from the recorded disc-shaped recording medium. The present invention relates to a means for mounting the disk-shaped recording medium to the main body of the recording and reproducing apparatus in the recording and reproducing apparatus.

Structure of the conventional example and its problems In the recording and reproducing apparatus described above, when recording a signal on a disk-shaped recording medium (hereinafter referred to as a disk) or reading a signal from a disk that has already been recorded, the recording and reproducing apparatus It has been proposed that loading a disc into the main body and removing the disc from the recording/playback apparatus main body (hereinafter referred to as the apparatus main body) should be done from the front of the apparatus main body.This proposal will be explained in more detail as follows. A disk plate capable of supporting a disk is provided in the main body of the apparatus, and the disk plate is configured to be able to move horizontally and pop out of the main body of the apparatus, and a gourd is placed on the protruded disk plate. By simply pressing the operation button , the disc tray reenters the main body of the apparatus, and is further lowered to place the disc in a recordable or reproducible position. In this case, especially in an optical recording/reproducing apparatus that uses laser light to record or reproduce signals, leakage of the laser light to the outside of the apparatus body becomes a problem. For example, in the United States, strict regulations have been enacted as safety standards for handling lasers, and it is desirable that laser light not leak outside the device body under any conditions while the device body is in operation. Especially when loading and unloading discs as described above,
It is required that the opening of the apparatus body be completely closed with a lid, and furthermore, it is desirable that the lid not be opened while the apparatus body is in operation.

OBJECTS OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a disk-shaped recording medium loading device whose lid does not open during operation of the device main body.

Structure of the Invention The disk-shaped recording medium mounting device according to the present invention is provided with a disk tray capable of supporting a disk, and this disk tray is configured to be horizontally movable between the inside and outside of the device main body. While the tray is moved into the main body of the apparatus, it is lowered and set at the recording (playback) position.A stopper piece is provided on the lid body that covers the opening for passing the disk plate in the main body of the apparatus. Also, with the disc tray in the recording (playback) position, the two parts of the storage case that holds the disc tray are placed opposite the stopper piece, and even if you try to open the lid in this state.'' This prevents the lid from opening (rotating) due to a collision with the storage case, and therefore can reliably prevent laser light from leaking outside from the opening. . In addition, when taking out a disc, the storage case rises together with the disc plate, so that the opposition between the storage case and the stopper piece is released, and the lid can be rotated.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. Fig. 1 shows the external appearance of the optical recording/reproducing device, Fig. 2 shows the main parts of the device as seen from the side, Fig. 3 shows an exploded perspective view of the main parts, and Figs. Each figure shows a diagram to explain the operation of the device.

In Figures 1 to 7, 1 is the device main body, 2 is the disk 3
This opening is provided at the front of the apparatus main body 1 and is used to take the liquid into the apparatus main body 1 or out from the apparatus main body 1. Reference numeral 4 denotes a lid body that covers the opening 2 from the outside, and has a shape that is sufficiently larger than the opening 2. A stopper piece 5 is provided facing downward on the left and right ends of the back surface of the lid body 4, and a protrusion 6 provided on a part of the stopper piece 6 is rotatably pivoted on the back surface of the front panel 7 of the device main body 1. The supporting part 08 is the pivot support. Although not shown, the stopper piece 6
A tension spring is stretched between the front panel 7 and the front panel 7 to bias the lid 4 in the closing direction, thereby closing the opening 2.

Reference numeral 9 designates a disk plate for supporting the disk 3, which is provided with a circular recess 10 corresponding to the disk 3, as shown in detail in FIG.
A notch 11 is provided on a radial path reaching the center of the disc 3 so that the laser beam hits the disc 3. Further, the disk plate 9 has rack portions 12 formed on each of a pair of sides parallel to the direction of insertion into the main body 1 of the apparatus. This rack section 12 is used to move the disk pan 9 in the horizontal direction when loading or unloading the disk 3.

Reference numeral 13 denotes a storage case provided within the main body 1 of the apparatus, which moves up and down within the main body 1 while storing and holding the disk plate 9 therein. The means for vertically moving the storage case 13 is known, but when the storage case 13 is in the lowered position, the shaft of the disk motor 14 enters the center hole of the disk 3, and its rotational force rotates the disk 3. At the same time, laser light is output from the optical end of Pinkup 15,
Recording or reproducing a signal to or from the disk 3 is performed on the disk 3. The pickup 16 reciprocates in the radial direction of the disk 30. When the storage case 13 is in the raised position, the tip opening of the storage case 13 is aligned with the opening 2 of the front panel 7.
By moving the disk plate 9 horizontally in this state, the disk plate 9 can be taken out of the apparatus main body 1 through the opening 2.

Projections 16 are provided at the left and right ends of the tip of the storage case 13. The stopper piece 5 provided on the lid body 4 and the protruding piece 16
It is formed in response to.

FIGS. 4 and 6 show the storage case 13 being lowered and in a recording/reproducing state. At this time, the end face of the protruding piece 16 comes into contact with or very closely opposes the stopper piece 6, so even if you try to open the lid 4 in this state, the stopper piece 5 collides with the protruding piece 16, causing the lid 4 to It does not rotate and will not open. However, there is no risk of laser light leaking from the aperture 2 in the recording/reproducing state.

Next, when the eject button 17 is pressed to remove or replace the disc 3, the recording/reproducing operation stops, and the mechanism that moves the storage case 13 and the disc tray 9 vertically and horizontally operates. rises, and as shown in FIG.
6 is removed from the position facing the stopper piece 5. Here, the disc plate 9 moves horizontally, and the lid body 4 is in the closed state.
While pushing open, most of the disk tray 9 itself appears outside the main body 1 of the apparatus. The lid 4 can be easily opened as shown in FIG. 7 unless there is an obstacle blocking its rotation.

In addition, when setting the disk 3 into the device main body 1,
When the play button 18 is pressed, the disc tray 9 moves horizontally, contrary to the above case, and enters the main body 1 of the apparatus, and then descends together with the storage case 13 and is set at the recording/reproducing position. The lid body 4 is closed by the action of a tension spring.

In addition, in the second embodiment, the protruding piece 16 was provided on the storage case 13 side due to the relationship with other parts, but the stopper piece 6 was not formed and the stopper piece 6 was directly adjacent to the front end surface of the storage case 13. They may also be arranged so that they face each other. Also, Figure 4~
In FIG. 7, reference numeral 19 denotes a side plate to which components constituting a mechanism for vertically moving the storage case 13 and horizontally moving the disk plate 9 are fixed.

Effects of the Invention As described above, according to the present invention, by preventing the lid from opening when the disc and disc tray are moved to the recording/reproducing position, the laser beam is not visible from the outside through the opening. Leakage of laser light from the opening can be completely prevented.
