Description

[Detailed description of the invention] The present invention relates to a vehicle-mounted disk performance device.

2. Description of the Related Art A joke box is generally known as a disk playing device that can store a plurality of disks and can sequentially select any of the stored disks for continuous performance. However, the main body of the conventional desk box itself was very large, and it was very troublesome to insert and remove the disk from the disk storage section, so it was mostly used for commercial purposes.

On the other hand, when considering an in-vehicle disk performance device,
Development has been delayed due to issues such as operability, miniaturization, and vibration countermeasures. Furthermore, even among in-vehicle tape playback devices that are becoming increasingly popular, there are very few so-called joke box type playback devices that can accommodate a plurality of cassette tapes and can sequentially select and play back a plurality of tapes in succession.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a junk box type in-vehicle disk performance device which is extremely compact, allows easy attachment and detachment of disks, has a high disk storage density, and has particularly sufficient vibration protection.

Recently, several types of means have been proposed to greatly increase the amount of information that can be accommodated by digitally inputting signals to the disk, compared to conventional audio disks that input analog signals. In particular, the method of using a disk, generally called a compact disk, which picks up signals using laser light, has a small diameter of 12 cm, making it easy to handle, and allows the performance device to be made smaller. The playing time is one hour on one side, which is approximately 1.5 times the amount of information that can be stored on both sides of a conventional audio disc. Therefore, for example, 50 discs can store 1,000 songs with a playing time of 3 minutes, and since the thickness of a compact disc is approximately 1.2 mm, the thickness of 50 discs is approximately 6 cm, and the inside It can accommodate as many as 1000 songs. By using a compact disk in this way, it is possible to provide an extremely small-sized joke box that can be used in a vehicle. By using the joke box of this invention, there is no need to separately prepare a disk storage box to accommodate a large number of disks, and it is possible to select and play songs from the disks without touching the disks, which improves driving safety. It is maintained.

The in-vehicle disk performance device according to the present invention includes a disk storage section that can accommodate a plurality of disks arranged in a predetermined pitch, a disk performance means that is movable in the disk arrangement direction of the disk storage section, and a disk storage section and a disk performance device. A disk moving means for moving the disk to and from the playing position of the means, and a regulating means provided for each disk storage position of the disk storage section to restrict the movement of each disk. The disk to be played is moved to the disk playing means while being released from the restricted state by the restricting means.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the overall structure of a disc playing device according to the present invention. In the figure, 1 is the main body of the device which stores a plurality of discs 2 and can automatically select and play one of the discs, and is supported on the front side of the device so that it can be opened and closed at its lower end. A door 3 is provided. The door 3 is opened and closed by a door switch 4 provided on the front of the main body. Reference numeral 5 denotes an operation section for sending various commands to the apparatus main body 1, and is connected to the apparatus main body 1 by, for example, a cable 6. The operation unit 5 includes a group of music selection switches 7 for specifying the disc number and track number to be selected, and a group of music selection switches 7 that can searchably store the title and track number of the storage disc, and store the stored contents in connection with disc replacement. It has a storage means 8 which can change the number of discs, and also has a display section that displays the selected disc number, track number, and operating mode of the machine.

FIG. 2 is a schematic plan view showing the internal structure of the device main body 1 in FIG. 1. In the figure, a disk storage section 10 in which a plurality of disks can be arranged and stored at a predetermined pitch is provided immediately behind doors 4a and 4b so that disks can be easily attached and detached. The disk storage section 10 includes a support base 11,
It is equipped with a plurality of partition plates 12 arranged at a constant pitch on this support base, and a plurality of partition plates 1
The disc 2 is housed and held in the slot formed by the disc 2.

FIGS. 3a and 3b show a front view and a side view of the disk storage section 10 seen from the rear, and each partition plate 12 has a disk at the rear end for regulating the rearward movement of the storage disk. It is equipped with a stopper 13. The disk stopper 13 is shown in FIG.
As shown in b, a semi-cylindrical guide cylinder 14 fixed to the end of the partition plate 12, a main shaft 15 provided to be movable up and down within this guide cylinder 14, and this main shaft 1
5 in the protruding direction (upward in the figure)
and a stopper pin 17 movably implanted in the main shaft 15 along the guide hole 14a of the guide cylinder 14.
and a cam 19 provided on the slider 18 constituting a disk moving means to be described later, which engages with the upper end of the main shaft 15 and presses it downward when the slider is moved, that is, when loading the disk.
(See Figure 3b).

In the disk stopper 13 having such a structure, when the disk is clocked, the main shaft 15 protrudes as shown in FIG. 4a, so that the stopper pin 17
is positioned substantially perpendicular to the main surface of the partition plate 12, and comes into contact with the outer periphery of the disk 2 stored in the disk storage portion 10, thereby restricting the disk from moving backward. When loading a disk, the cam 19 (see FIG. 3b) provided on the slider 18 moves together with the slider 18 to press downward the main shaft 15 corresponding to the disk to be loaded, so the stopper pin 17 is moved as shown in FIG. 4b. Then, it moves along the guide hole 14a in conjunction with the main shaft 15 to unlock the disk. The lock is released only for the disc being played, and when the disc is returned to the disc storage section 10 after the performance, the disc becomes locked again.

In FIG. 2, for example, at the rear of the disk storage section 10, a disk playing means 21 is provided so as to be movable in the disk arrangement direction of the disk storage section 10 along a pair of guide bars 20a, 20b. On this disk playing means 21, a previously designated disk is moved from the disk storage section 10 to the playing position of the disk playing means 21, and after the performance is finished, it is moved from the disk playing section 21 to the disk storage section 10.
A disk moving means 22 is mounted that performs a so-called loading operation to return the disk to the storage device. As shown in FIG. 3b, the disk moving means 22 includes a slider 18 movable in a direction perpendicular to the direction in which the disks are arranged, and a pair of rollers 23a and 23b attached to the slider so as to sandwich the outer periphery of the disks. The disc is moved by pressing the outer periphery of the disc via these rollers.

The disk playing means 21 is the disk moving means 2.
Clamping means for clamping the disk loaded in the playing position by 2 into a playable state;
It is equipped with a drive means for rotationally driving the clamped disk, a pickup device for picking up information on the disk, and the like. When performing a disc performance, the disc is moved in the disc arrangement direction according to the designated disc storage position, and after the loading of the designated disc by the disc moving means 22 is completed, the performance is performed.

In the disk storage section 10, the support base 11
As shown in FIG. 3b, the disc is equipped with a stopper 24 that prevents the stored disc from slipping forward. Furthermore, a regulating member 25 made of urethane or the like is provided on the back side of the door 3 to prevent the storage disk from moving from the storage position due to external disturbances or the like.

When a disc playing device having such a configuration is installed in an automobile, as shown in FIG. 5, the main body 1 of the device is installed, for example, in a trunk room, and the operating section 5 is installed, for example, near the driver's seat. For the device main body 1,
As shown in FIG. 6, vibration countermeasures are taken by surrounding the main body 1 with a vibration isolating member 26 such as styrofoam, urethane, rubber, or air mat. The vibration isolating member 26 may be a spring or the like, but when considering installation in a trunk room etc., it is necessary to take measures against temperature, so vibration isolating materials such as styrofoam or urethane, which also have a heat insulating effect, are optimal. . The installation location of the device main body 1 is not limited to the trunk room, but may be in a space inside the vehicle, and the operating section 5 may be provided at a location that can be operated by a passenger.

In the above-mentioned in-vehicle disk performance device,
The main body of the device has a high disk storage density and is very small, so it can be easily installed in the trunk of a car, eliminating wasted space inside the car, and you can easily and safely perform disk performances just by operating the control unit. You can enjoy it. Further, since it is not necessary to attach or detach the disk, and it is possible to select songs on the disk and play continuously without touching the disk, even the driver can easily operate it and maintain driving safety. Furthermore, since the main body of the apparatus is installed via a vibration isolating member, the vibrations of the automobile are blocked by the vibration isolating member, and disc performance can be performed satisfactorily.

As explained above, in the in-vehicle disk performance device according to the present invention, the movement of each disk is controlled by the regulating means provided for each disk storage position of the disk storage section that can accommodate a plurality of disks arranged in a predetermined pitch. When performing a disc performance, the disc moving means moves the disc to be played to the disc playing means while releasing it from the restricted state by the restricting means, thereby removing the restricted state by the restricting means. Only the disk being played is released from the disk, and the movement of the other disks is restricted by the action of the restricting means, so it is possible to reliably prevent the disk from leaving the storage position due to external disturbances such as vibrations. In particular, since the disk has a shape that is easy to move, an in-vehicle disk playing device with sufficient vibration protection can be obtained.
