Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc mounting device for a disc playback device, and particularly to a disc mounting device for a disc playback device, and particularly to a disc mounting device for a disc playback device. This is intended to be done with a simple configuration. When the disc is first inserted into the disc storage part and then the disc is put into the playing state, the disc inserted into the disc storage part must be engaged with the disc holding/driving mechanism, and when playing, the disc must be inserted into the disc storage part. It is necessary to separate it from the Therefore, the present invention has a configuration in which the disk storage section in which the disk is stored is moved from the opening side position (the position where the disk is inserted) to the performance side position (the position where the disk is held and driven), and this movement This configuration combines a parallel linear movement parallel to the disk holding/driving mechanism and a subsequent diagonal movement. and,
By utilizing the diagonal movement of the disk storage section, engagement between the disk and the disk holding/driving mechanism can be achieved with a simple structure, and the structure is configured such that there is no contact with the disk storage section during the performance state. It is. Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. FIG. 1 shows an external perspective view of a disc playback device 1 having a disc mounting device according to the present invention. The main body of the disc playback device 1 is provided with a disc insertion slot 2 and a lid 5 (shown in FIGS. 2 and subsequent figures) that covers the disc insertion slot 2. The state shown in FIG. 1 is an open state, and at this time, the disk storage section 3 is raised to an open position facing the disk insertion slot 2. Therefore, disk D
It is extremely easy to insert and remove (withdraw). The configuration of the disk storage section 3 is shown in FIGS. 2, 3,
This is clearly shown in FIG. Disk storage section 3
It is pocket-shaped (bag-shaped), and has a through hole 3a bored in the approximate center thereof into which the disk holding/driving mechanism 4 can be inserted. The state shown in FIG. 2 is a state in which the disk storage section 3 is raised to face the disk insertion slot 2, and at this time, the lid 5 is opened. Therefore, disk D can be inserted.
When the disk D is inserted into the disk storage portion 3 through the disk insertion opening 2, the disk D is inserted by suction by the loading mechanism 6 . Loading mechanism 6
(shown only in FIG. 2) is a pair of loading pins 7 facing the inside of the disk storage section 3, a lever 8 on which the loading pins 7 are erected, and a lever 8 for storing the disk. A support shaft 9 rotatably supported on the upper surface of the disk storage section 8, a rod 10 connected to the lever 8, a guide section 3b provided on the upper surface of the disk storage section 3 for freely guiding the rod 10, and this guide. It consists of a coil spring 11 wound around the rod 10 between the portion 3b and the rear end 10a of the rod 10. Due to the coil spring 11, the pair of loading pins 7 are
It is constantly biased inward (in the direction of sandwiching the disk). Therefore, when you grasp the disk D with your fingers and insert it into the disk storage part 3, after the pair of loading pins 7 exceed the diameter of the disk D,
The disk D is automatically attracted by a pair of loading pins 7 that are urged inward by a coil spring 11. The disk D is sucked to a position where its insertion tip side comes into contact with a disk insertion detection switch _S1 provided inside the disk storage portion 3 and a locking pin 12 provided opposite thereto. This state is shown in FIG. At this time, a part of the disc D protrudes from the disc playback device 1 . That is, when detaching (pulling out) the disk D, it is possible to grasp this protruding portion with fingers. Now, the disk storage section 3 moves from the opening side position shown in FIG. 3 to the performance side position shown in FIG. 4 via the path shown by the broken line in FIG. The moving mechanism 13 for performing such movement will be explained with reference to FIG. 2. The moving mechanism 13 includes a guide pin 14 provided in the disk storage section 3 (only two on one side are shown in FIG. 2), a guide mechanism 15 provided on the device main body side that guides the guide pin 14, and a disk storage section. 3, this engaging pin 16
A feed nut 1 having an engaging portion 17a that engages with
7. Feed screw 1 that screws into this feed nut 17
8. Feed motor 1 that rotates this feed screw 18
It consists of 9. Therefore, feed motor 1
By rotating 9, the disk storage section 3 is moved from the position shown in FIG. 3 to the position shown in FIG. When the disk storage section 3 is in the performance side position shown in FIG. 4, the disk D inserted into the disk storage section 3 is held and rotationally driven by the disk holding/driving mechanism 4 . The disk holding/driving mechanism 4 includes a motor 20 supported by the apparatus main body, a drive plate 21 fitted to the rotating shaft of the motor 20, and a holder that is pressed onto the drive plate 21 by magnetic force and holds the disk D by sandwiching it therein. A plate 22, a rotating member 23 that rotatably supports the holding plate 22, and a rotating member 23.
It is composed of a support shaft 24 fixed to the device main body 1 so as to be rotatably supported relative to the device main body.
A magnet is embedded in the driving plate 21 side, and a magnetic material is embedded in the holding plate 22, and the holding plate 22 is embedded in the driving plate 21.
It is pressed against the surface by magnetic force. Now, when the disk storage section 3 is in the position shown in FIG. When the disk storage section 3 moves linearly parallel to the disk holding/driving mechanism 4 and further lowers obliquely, the holding plate 22 and the drive disk 21 enter into the disk storage section 3.
When the drive plate 21 comes to engage with the center hole of the disk D in the disk storage section 3, further movement of the disk D is prevented, and only the disk storage section 3 moves to the position shown in FIG. 4. Therefore, the fourth
In the performance position shown in the figure, the contact between the disc D, the disc insertion detection switch _S1 , and the locking pin 12 is released. Further, in the position shown in FIG. 4, the rear end 10a of the rod 10 is in contact with the rear wall 1a (see FIG. 2) of the disc playback device, and the pair of loading pins 7 are in the position shown in FIG. Since it opens in the opposite direction of the arrow, the pair of loading pins 7 and the disk D are also released from contact. Therefore, when the disc storage section 3 is in the playing position shown in FIG. 4, the disc D is held only by the disc holding/driving mechanism 4 and is rotated smoothly. Next, the lid opening/closing mechanism 25 will be explained. The lid 5 can be opened and closed with respect to the main body of the disc playback device 1 (in this embodiment, it can be moved up and down; see FIG. 2), and is always urged upward (in the direction of closing the lid) by a coil spring 26. There is. A cam portion 5 is provided on the lid body 5.
a is provided, and when the disk storage section 3 is in the opening side position, the lower end 3c of the disk storage section 3 is in contact with the upper surface of the cam section 5a, so the lid body 5 is in the open state (No. (See Figure 5). Now, moving mechanism 1
3, when the disc storage part 3 starts to move to the performance side position, the lower end 3c of the disc storage part 3 comes into contact with the inclined surface of the cam part 5a, and the lid body 5 is closed by the elastic force of the coil spring 26. In the playing state, the lid is completely closed.
Conversely, when the disk storage section 3 starts to move from the performance side position to the opening side position, the lower end 3c of the disk storage section 3 pushes down the inclined surface of the cam section 5a, and the lid body 5
moves in the direction of opening the lid (see Figure 6). That is, the cam portion 5a, the coil spring 26, and the lower end 3c of the disk storage portion 3 constitute a lid opening/closing mechanism 25 . Finally, the operation of the disk mounting device according to the present invention will be summarized with reference to the time chart shown in FIG. It is now assumed that the lid body 5 is in an open state and the disk storage section 3 is in the opening side position. From this state,
When the disk D is inserted into the disk storage portion 3 through the disk insertion opening 2, the disk D is sucked and inserted by the loading pin 7 and comes into contact with the disk insertion detection switch _S1 . Disk insertion detection switch S ₁
When turned on, the feed motor 19 starts rotating forward, and the disk storage section 3 starts moving. At this time, the up detection switch _S2 (see FIG. 2) is turned off. The disk D engages with the disk holding/driving mechanism 4, and the movement of the disk storage section 3 continues until the end, but when the movement of the disk D is blocked, the disk insertion detection switch _S1 is turned off. . When the disk storage section 3 moves to the performance side position, the feed nut 17 comes into contact with _the down detection switch _S3 , which turns on and the rotation of the feed motor 19 stops. This state is the disc's playing state. To eject disk D, press eject button 27.
(shown in FIG. 1). Then, the feed motor 19 starts rotating in reverse, and the disk storage section 3
starts moving to the opening side position. The down detection switch _S3 is then turned off. As the movement of the disk storage section 3 progresses and the disk D is released from the disk holding/driving mechanism 4 , the disk insertion detection switch _S1 is also turned on. When the disk storage section 3 moves to the opening side position, the feed nut 17
comes into contact with up detection switch S ₂ , and this switch
_S2 is switched on and the rotation of the feed motor 19 is stopped. After that, when the disk D is pulled out from the disk storage part 3, the disk insertion detection switch S ₁
is also turned off. It is convenient to use a microcomputer for such control, for example.
Since the details are outside the scope of the article, the explanation will be omitted. According to the present invention described above, since the disk is engaged with the disk holding/driving mechanism during the diagonal movement of the disk storage section, the disk holding/driving mechanism can easily hold the disk. Moreover, there is an advantage that the contact between the disc storage section and the disc is released at the end of the diagonal movement (during performance). That is, in order to engage the disc inserted into the disc storage part with the disc holding/driving mechanism and to release the contact between the disc and the disc storage part during performance, the disc storing part must be connected to the disc holding/driving mechanism. After the disk and the disk holding/driving mechanism are engaged, it is necessary to move the disk holding part in a vertical direction, and then move the disk holding part away from the disk holding/driving mechanism in parallel to release the contact between the disk and the disk holding part. However, since the present invention utilizes diagonal movement that combines these,
Only one direction of movement is required (of course, a separate parallel linear movement is required to pull the disk with a portion (gripping space) protruding outside the playback device into the playback device);
The structure is simple. Furthermore, in order to engage the disk with the disk holding/driving mechanism, it is conceivable to rotate the disk storage part, but in this case, the rotation range of the tip of the disk storage part becomes wider, and the device becomes larger. Although this tends to happen, if diagonal movement is used as in the present invention, the device can be made smaller.
