Abstract

PROBLEM TO BE SOLVED: To enable smooth ejection of a magazine regardless of the weight and type of the magazine, by ejecting the magazine to a position protruding from an insertion port, not by a force of a spring but by mechanical power of a driving mechanism. SOLUTION: A holder 12 for holding a magazine M is provided on a mounting portion A within a casing 11. This holder 12 is moved by a rotating force of a cam plate 21 driven by a motor. When the holder 12 moves in a direction X2, a lock member 14 rides on an unlock member 17 so that the magazine M within the holder 12 is unlocked. The magazine M protrudes from an insertion port and may be pulled out manually. Since the magazine is ejected by the movement of the holder 12, smooth ejection is realized. Also, since the holder 12 is driven by using mechanical power of the cam plate 21 for lifting a disk selection portion, no dedicated driving source for driving the holder 12 is required.

2. Description of the Related Art FIG. 5 is a side view showing a vehicle-mounted disc changer as an example of a conventional magazine loading type disc device from the side end surface direction. A magazine loading portion (loading chamber) A is provided inside the housing 1, and the magazine M is inserted into the loading portion A from the insertion port of the housing 1 in the X direction. The loading section A is provided with an installation table 2, and the installation table 2 is rotatably provided with a lock member 3 that fits into the lock recess Ma of the loaded magazine M. A discharge member 4 is provided above the loading section A so as to be movable in the left-right direction in the drawing, and the discharge member 4 is biased in the right direction in the drawing by a tension spring 5.

When the magazine M is inserted in the X direction,
The ejecting member 4 is pushed against the force of the spring 5 by the leading end of the magazine M, and then the lock recess Ma formed at the bottom of the magazine M is fitted into the lock member 3 to lock the magazine M. . In the housing 1, a disk selection unit is provided movably up and down on the back side of the paper of FIG.
The disc selection unit faces any of the discs in the magazine M. At that position, the disc is pulled out from the magazine M, and the disc is driven by a disc drive unit such as provided in the disc selection unit to reproduce the signal recorded on the disc. The reproduced disc is returned to the magazine M.

When the magazine M is ejected, the lock member 3 is driven counterclockwise by a mechanism (not shown),
The engagement between the lock member 3 and the lock recess Ma is released.
As a result, the ejection member 4 is pulled rightward in the drawing by the force of the spring 5, and the magazine M is pushed out from the insertion port by the ejection member 4.

[0005]

In the conventional magazine loading type disk device shown in FIG. 5, when the magazine M is ejected, the elastic force of the tension spring 5 is utilized.
Therefore, if the elastic force of the tension spring 5 is weak,
The magazine M may not be reliably ejected. For example, in the case where a large number of compact discs such as 10 or 12 are stored in the magazine M, the total weight of the magazine M and the discs becomes large, and the elastic force of the tension spring 5 ensures the magazine M. Occasionally, it cannot be discharged. Further, when the X direction is downward and the insertion opening of the housing 1 is installed upward, the magazine M may not be able to be lifted only by the elastic force of the tension spring 5. In order to surely eject the magazine M, the elastic force of the tension spring 5 may be increased,
In this case, when the magazine M is inserted in the X direction, the resistance force required to push in the ejection member 4 becomes large, and it becomes difficult to manually insert the magazine M reliably. Further, if the elastic force of the tension spring 5 becomes too large, when the lock by the lock member 3 is released, the magazine M jumps out vigorously from the insertion port, which makes the operation feeling uncomfortable.

Further, in the structure shown in FIG. 5, when the magazine M is installed on the installation table 2, the magazine M
Since the bottom of the magazine M is restrained by the lock member 3 and the upper end of the magazine M is pulled rightward in the drawing by the elastic force of the tension spring 5, the magazine M is apt to be distorted. If this distortion becomes large, it may be difficult to pull out the disc from the magazine M by the disc selection unit.

The present invention is to solve the above-mentioned conventional problems. By ejecting the magazine by using the power of a motor or the like instead of the spring force, the ejecting of the magazine is always smooth and reliable even when the weight of the magazine is large. It is an object of the present invention to provide a magazine-loading type disk device that can be operated.

Further, according to the present invention, when the magazine is discharged by using the power of a motor or the like, a separate power source for discharging only the magazine is not provided, and it is also used for the operation of other mechanisms, so that the entire apparatus can be operated. It is an object of the present invention to provide a magazine-loading type disk device that can simplify the structure of.

Since No. 3 slides in an arc portion having a constant radius R, the position of the drive shaft 43 does not change, the drive link 41 and the drive plate 33 stop, and the disk selection unit F stops at the bottom.

On the other hand, the cam plate 21 rotates in the CW direction and β
When the angle range is reached, the drive shaft 25 comes out of the arc portion of the cam hole 21a and enters the drive portion. When the cam plate 21 further rotates in the CW direction after the drive shaft 25 reaches the inside of the drive unit, the drive unit of the cam hole 21a causes the drive shaft 25 to move in the X direction.
The holder 12 that is driven in two directions and is integral with the drive shaft 25
Moves in the direction of the insertion port 11a (X2 direction). In addition,
The rotation angle of the cam plate 21 in the CW direction is determined by the linear sensor 24.
The output can be recognized from the output (FIG. 4 (C)), and the cam plate 21 rotates by an angle of (α + β) based on the output from the linear sensor 24, and the holding body 12 reaches the position of FIG. 2 (B). At the same time, the motor stops and the cam plate 21 stops. Holder 1
The relationship between the moving position of 2 in the X2 direction and the output of the linear sensor 24 is as shown in the diagrams of FIGS. 4 (B) and 4 (C). It should be noted that the limit switch may detect that the holder 12 has moved to the position shown in FIG. 2B, and the motor may be stopped.
