That is, the positioning plate 12
Due to the surface contact between the position e and the positioning surface portion 59a, further insertion and movement of the pickup unit 12 is restricted, and the position where the two come into surface contact is the mounting position of the pickup unit 12. Therefore, if the user pushes the pickup unit 12 to a position where the pickup unit 12 can be inserted without being particularly conscious of the positioning, the pickup unit 12 can be positioned at a predetermined mounting position in the housing portion 10. I have. The positioning plate 12e has a surface portion 10a.
A protruding portion 59b protruding to the side is provided. Projection 59b
Are formed at positions corresponding to the positioning holes 12f formed in the positioning plate 12e of the pickup unit 12, and when the pickup unit 12 is mounted at the predetermined mounting position as described above, the positioning is performed in the positioning holes 12f. The member 59 can be inserted. By positioning the pickup unit 12 by inserting the protrusion 59b into the positioning hole 12f in this manner, it is possible to prevent the mounting position from being largely displaced vertically and horizontally.

A-3. Disk rack Next, the disk rack 1 will be described with reference to FIGS.

a is formed, and a portion 64b having a reduced width is formed at the center side. A wide portion 64c is also formed on the open side opposite to the surface portion 11a. Here, by forming the groove 64 whose width changes in this way, the above-described lever mechanism 21 can be used when removing the disk rack 11 from the housing 10 or when inserting the disk rack 11 into the housing 10. The engagement between the pin member 20c and the pin member 41c of the disc rack pushing mechanism 40 and the groove 64 is changed according to the position of the disc rack 11. By changing the engagement state in this way, it is possible to obtain an effect of suppressing excessive protrusion of the disk rack 11 when removing the disk rack 11, which will be described later.

A-4. Pickup Unit Next, the pickup unit 12 will be described with reference to FIG. The pickup unit 12 includes a front surface portion 12b, a pickup 12a that performs recording / reproducing processing on the disk D, and a flat pickup holding portion 90 that holds the pickup 12a, a control circuit board (not shown), and the like on its upper surface. A substrate protection cover portion 91 provided to cover the substrate disposed on the surface portion 12b side of the pickup 12a on the pickup holding portion 90, and standing upright (right side in the drawing) of the pickup holding portion 90. And a positioning plate 12e. Here, as described above, the positioning plate 12e is provided with the positioning hole 12f for positioning the pickup unit 12 inside the casing 10.

The pickup holding section 90 is a substantially rectangular flat plate member extending in the insertion direction of the pickup unit 12, and has the pickup 12a mounted on its inner side (right side in the drawing) and a control circuit board on the surface section 12b side. It is installed.
Here, the control circuit board is covered with a box-shaped board protection cover section 91, thereby suppressing damage to the control circuit board when the pickup unit 12 is taken out or mounted. The board protection cover portion 91 is formed in such a size as to be in contact with the bottom surface of the disk rack 11 when the disk rack 11 and the pickup unit 12 are mounted in the housing portion 10 (see FIG. 2). This prevents a gap from being formed between the disk rack 11 and the pickup unit 12 when both are mounted. By thus preventing a gap from being formed between the two, the removal of the pickup unit 12 in a state where the disk rack 11 is mounted can be regulated. This will be described later.

On both sides of the pickup holding portion 90, a rail portion 90a is formed to be guided by the above-mentioned rail groove 52 (see FIGS. 5 and 6) when the pickup unit 12 is inserted or mounted. The rail portion 90a is slidably engaged with the rail groove 52, so that the user does not need to be conscious of a detailed operation such as accurately adjusting the insertion direction, and simply performs a simple operation such as aligning the insertion direction to some extent. The pickup unit 1 to be inserted

Is formed by notching a portion of the rail portion 90a on the surface portion 12b side, and a step is formed by the notch 90b. In the present embodiment, the removal of the pickup unit 12 is restricted by using the step. However, this will be described later.

The surface portion 12b is provided with a power supply terminal for supplying power to the control circuit board and a terminal portion 93 having a signal input / output terminal for transmitting and receiving various control signals and the like. When the device 100 is used, a predetermined power supply line or signal line is connected to the terminal 93.

B. Removal and Installation of Disk Rack Next, in the disk changer device 100 having the above-described configuration, a user operation for removing the disk rack 11 from the housing unit 10 and an accompanying operation, and a predetermined position in the housing unit 10 The operation of the user when the disk rack 11 is mounted and the operation of each unit accompanying the operation will be described.

First, the case where the disk rack 11 is taken out when the disk rack 11 is mounted in the housing 10 will be described. When the disk rack 11 is mounted in the housing 10, a force as shown in FIG. As shown in the figure, when the disk rack 11 is mounted in the casing 10, the pin member 41c is engaged with the portion 64c of the side surface portion 63, whereby the urging force of the coil spring 42 causes A force is applied to move the disk rack 11 to a certain surface side. On the other hand, the portion 6 of the side portion 63
4a is engaged with a pin member 20c, whereby the disk rack 1 is pressed against the urging force of the coil spring 42.
1 is kept stationary. Such a stationary state is a normal mounting position of the disk rack 11 in the housing 10.

From such a mounting position, the disk rack 1
When taking out 1, the user performs a pressing operation on the distal end portion 20a. Then, the lever 20 of the lever mechanism 21 is rotated about the shaft 31 as described above,
Accordingly, the pin member 20c is moved downward along the insertion hole 30c (see FIGS. 2 and 3). As described above, when the pin member 20c is moved downward, the engagement between the portion 64a and the pin member 20c is released, as shown in FIG. On the other hand, the portion 64c and the pin member 41
c, the engagement state with the coil spring 42 is maintained.
Causes the disk rack 11 to start moving toward the front side.

Then, while the user presses down the distal end portion 20a, the urging force of the coil spring 42 is used as shown in FIG.
When the disk rack 11 is further moved from the state shown in FIG. 12 to the front side, as shown in FIG. 12, the portion 64b and the pin member 20c are engaged, thereby keeping the disk rack 11 stationary. That is, while the distal end portion 20a is pressed by the user, the movement of the disk rack 11 to the surface side from the position where the portion 64b and the pin member 20c are engaged is restricted. In addition, movement of the above-described pin member 41c toward the front surface side from the position where the portion 64b and the pin member 20c engage with each other is regulated by the insertion hole 43c. That is, FIG.
As shown in (1), the force of the coil spring 42 does not act on the disk rack 11 stopped by the engagement between the portions 64b and 20c.

Thereafter, when the user releases his / her hand from the distal end portion 20a, the lever 20 is rotated by the urging force of the coil spring 32 of the lever mechanism 21, and the pin member 20 is thereby moved.
c is moved upward along the insertion hole 30c. As a result, as shown in FIG. 13, the engaged state between the portion 64b and the pin member 20c is released. In this state, since the surface 11a of the disk rack 11 is stationary with the portion protruding from the housing 10, the user grips the protruding portion of the surface 11a of the disk rack 11 and Can be easily taken out.

In this embodiment, the portion 64 as described above is used.
a, a groove 64 having a portion 64b and a portion 64c is formed in the side surface 63 of the disk rack 11 and the housing 1
By providing the lever mechanism 21 having the pin member 20c and the pin member 41c and the disc rack pushing mechanism 40 on the 0 side, the above-described operation of taking out the disc rack 11 is enabled.

That is, when the distal end portion 20a is pressed down, the coil spring 4 of the disc rack pushing mechanism 40 is moved.
After the disk rack 11 is moved to the front side to some extent using the force of 2, the disk rack 11 is temporarily stopped by the engagement between the portion 64b and the pin member 20c. Then, after the user releases his / her hand from the distal end portion 20a, the portion of the disk rack 11 protruding from the housing 10 can be grasped and taken out by the user. By doing so, the following effects can be obtained. As a conventional disk rack removal mechanism, a mechanism that pushes out a disk rack by using an urging force of a spring or the like in accordance with a pressing operation of a lever or the like has been used. However, in the conventional mechanism, since only the push-out mechanism is mounted, when the disk rack is lightweight such that the number of disks accommodated in the disk rack is small, the disk rack pops out due to the force of the spring, and the disk rack 11 may be damaged. Was. On the other hand, if the spring force of the spring for pushing out is weakened to prevent the above-mentioned jumping out, there arises a problem that the disc rack cannot be pushed out when the weight accommodates a large number of discs. On the other hand, as described above, the disk rack 11 is moved to a certain extent by the pressing operation of the pin member 20c as in the present embodiment, and the movement of the disk rack 11 is restricted when the operation of the pin member 20c is not released. It is possible to prevent a problem such as a protruding disk rack. Further, while the pin member 20c is pressed, excessive movement of the disk rack 11, that is, jumping out can be regulated, so that it is not necessary to weaken the spring force of the coil spring 42 that generates the force for pushing out the disk rack 11. Also, when a large number of disks D are stored in the disk rack 11, the disk rack 11 can be pushed out.

In this embodiment, the disk rack 1
As a structure for preventing the disk rack 11 from jumping out and for reliably pushing out the disk rack 11 to a position where it can be easily taken out, a mechanical mechanism such as the lever mechanism 21 or the disk rack pushing mechanism 40 is used without using electronic control or the like. The structure is adopted. Therefore, a power supply circuit, a control circuit, and the like are not required, and the configuration is simple.

Next, when the disk rack 11 is mounted in the housing 10, the groove 64 and the side surface 65 on the disk rack 11 and the protruding rail 51 on the housing 10 are related. The disk rack 11 is inserted so as to fit. At this time, the pin member 41c and the portion 64c engage with each other to receive a pushing force due to the urging force of the coil spring 42, but the user moves the disk rack 11 in the insertion direction against this. Then, when the disk rack 11 is inserted to a predetermined mounting position, as shown in FIG. 10, the pin member 20c and the portion 64a are engaged, and the disk rack 11 is in a stationary state. Until such a state is reached, the user can mount the disk rack 11 at a predetermined mounting position by simply inserting the disk rack 11.

C. Removal and Mounting of Pickup Unit Next, a case where the pickup unit 12 is removed when the pickup unit 12 is mounted in the housing 10 will be described. In the present embodiment, the pickup unit 12 can be removed only when the disk rack 11 is removed. After the disk rack 11 is removed by the above-described operation, the pickup unit 12 is removed. The case will be described.

When the pickup unit 12 is to be removed from the housing unit 10, the screw 12d is first removed to release the mounting state between the housing unit 10 and the pickup unit 12 by screwing. In this embodiment, the screw 1
Pickup unit 12 other than screwing by 2d
Is not fixed, so the screw 12d
Is removed, the user grips the vicinity of the surface portion 12b and pulls out the pickup unit 12 to the near side.

Here, when the pickup unit 12 is pulled out substantially horizontally by the user, FIG.
As shown in FIG. 9A, a step formed by the cutout portion 90b of the rail portion 90a immediately after the pull-out operation (FIG. 9).
) And a protrusion 53 (see FIGS. 5 and 6) formed on the inner wall side surface 50 of the housing 10. That is, the pickup unit 12 cannot be pulled out horizontally as it is,
As shown in FIG. 14B, the user moves the vicinity of the surface portion 12b slightly upward so that the step formed by the cutout portion 90b does not abut on the protrusion 53, and in this state, Pull out the pickup unit 12 to the near side. Here, when the disk rack 11 is mounted on the housing 10, the substrate protection cover 91 of the pickup unit 12 and the bottom of the disk rack 11 are in contact with each other. Can not be moved. That is, the pickup unit 12 cannot be pulled out while the disk rack 11 is mounted.
This is because the pickup unit 12
a and electronic components such as a control circuit board are mounted on the pickup unit 12 by preventing the pickup unit 12 from being pulled out when the disk rack 11 is mounted as described above. The precise electronic components to be mounted are the pickup unit 12
When the drawer is pulled out, it is possible to prevent the disk rack 11 or the like from being damaged by collision.

On the other hand, when the disk rack 11 is removed, as shown in FIG. 14B, the pickup unit 12 can be moved upward, so that the pickup unit 12 is formed by the projection 53 and the notch 90b. After moving the pickup unit 12 upward to a position where it does not contact the step, the pickup unit 12 can be detached from the housing 10 by pulling the pickup unit 12 forward.

As described above, in the present embodiment, the pickup unit 12 can be removed by an easy operation, and the following effects can be obtained. Since the pickup unit 12 has precision electronic components mounted thereon as described above, operations such as replacement of components due to maintenance or failure, or replacement of all the pickup 12a and the control circuit board are often performed. In particular, when the disc changer device 100 is used for business (for example,
There is a disc changer device mounted on a karaoke device installed in a store or the like), the use frequency of the pickup 12a is high, the number of times of maintenance as described above needs to be increased, and the possibility of replacement due to occurrence of a failure is required. Will also be higher. In the conventional disc changer device, the pickup unit is fixed to the housing, and the fixing position of the pickup unit is fixed due to a structural reason such as disposing a disc rack on the front surface, which requires inevitable attachment / detachment work. It was common to be on the back side inside the housing. For this reason, when performing maintenance or replacement,
There is a problem that the work of removing the pickup unit is complicated. On the other hand, the disc changer device 100 according to the present embodiment is designed in consideration of the fact that the pickup unit 12 can be easily removed, and the user can easily remove the pickup unit 12d as described above. It can be removed. Therefore, maintenance and replacement work can be simplified.

Next, the operation when the pickup unit 12 is mounted at a predetermined mounting position in the housing section 10 and the operation of each section of the disc changer apparatus 100 will be described. In this case, the user places the positioning plate 12e of the pickup unit 12 at the top and the housing 10
The pickup unit 12 is inserted into the opening 10c. At this time, in order to avoid contact between the protrusion 53 and the step formed by the cutout portion 90b, the pickup unit 12 is kept lifted to such an extent that the protrusion 53 and the cutout portion 90b do not contact. Then, the pickup unit 12 is inserted into the back side of the housing 10. That is, FIG.
The operation reverse to that at the time of removal shown in FIG. 4 (b) is performed.

When the pickup unit 12 is inserted in this manner, as shown in FIG. 15, the positioning plate 12e comes into surface contact with the positioning surface 59a of the housing 10 so that further movement in the insertion direction is prevented. Be regulated. The contact between the positioning surface portion 59a and the positioning plate member 12e in this manner positions the pickup unit 12 at an accurate mounting position in the insertion direction. Also, the positioning surface 59a and the positioning plate 12
When the pickup unit 12 is inserted to a position where it makes surface contact with e, the protrusion 59b is inserted into the positioning hole 12f, whereby the pickup unit 12 is positioned at an accurate mounting position in the vertical and horizontal directions.
Therefore, the user can insert the pickup unit 12 into the correct mounting position by a simple operation such as simply pushing in the insertion direction without performing a work such as fine adjustment of the insertion direction to mount the pickup unit 12 at the mounting position. After inserting the pickup unit 12 to the correct mounting position in this manner, the mounting operation of the pickup unit 12 is completed by mounting and fixing the housing unit 10 and the pickup unit 12 with the screw 12d.

In this embodiment, the pickup unit 1
2 can be easily removed from the housing 10, and the pickup unit 12 can be easily attached to a predetermined position in the housing 10. Therefore, maintenance work and replacement work of the pickup unit 12 described above are simplified.
