[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magazine insertion / ejection device used for a compact disc (CD) disc changer device or the like.

[0002]

2. Description of the Related Art FIG. 2 shows a magazine 1 for storing a plurality of disks. In FIG. 2, reference numeral 2 is a housing having an open front surface, and 3 is a partition plate arranged in parallel in the housing 2, and a disc is inserted between the partition plates 3.

FIG. 3 shows a disc changer device using the magazine 1. In FIG. 3, reference numeral 4 denotes an apparatus main body, and an opening 5 into which the magazine 1 is inserted is formed on the front surface of the apparatus main body 4. The device body 4
Inside, there is a disc pull-out mechanism for pulling out and storing the disc from the magazine 1, a loading mechanism for transferring the disc pulled out from the magazine to the turntable, a drive mechanism for rotationally driving the turntable, and a rotating disc. An optical pickup mechanism for reading information is stored.

FIG. 4 shows a magazine insertion / ejection device in the disc changer device. In FIG.
Is a chassis housed in the apparatus main body 4, and a sliding plate 7 is slidably supported on an upper surface plate 6a of the chassis 6. Reference numeral 7a is a bent piece formed by bending the tip of the sliding plate 7 by approximately 90 °. Reference numeral 8 denotes a spring that is hung between the protrusion of the upper surface plate 6a and the protrusion of the sliding plate 7. The elastic force of the spring 8 causes the sliding plate 7 to move into the magazine insertion slot 9 of the chassis 6.
Biased in the direction. 10a and 10b are leaf springs, and one ends of the leaf springs 10a and 10b are attached to the upper plate 6a. 11a and 11b are leaf springs 10a and 10b
Is a roller held at the other end of the leaf springs 10a, 10
Due to the elastic force of b, the rollers 11a and 11b move to the chassis 6
The upper surface of the magazine 1 inserted from the magazine insertion opening 9 is pressed.

FIG. 5 schematically shows the conventional magazine lock mechanism. In FIG. 5, 12 is an L-shaped groove formed on the upper surface of the magazine 1, 13 is a lever rotatably supported by the chassis 6 by a shaft 14, and one end of the lever 13 has the L-shape. A lock pin 15 that enters the groove 12 is provided. Reference numeral 16 is a spring for urging the lever 13 in the counterclockwise direction.

When the magazine 1 is inserted through the magazine insertion slot 9 of the chassis 6 as shown in FIG. 4, the rollers 11a, 1
1b hits the upper surface of the magazine 1 and urges the magazine 1 downward. When the magazine 1 is further inserted, the tip of the magazine 1 hits the bent piece 7a of the sliding plate 7 and the sliding plate 7 slides backward against the elastic force of the spring 8. In the process of inserting the magazine 1, the lock pin 15 is locked in the groove 12 of the magazine 1.
to go into. When the magazine 1 is further inserted, the lever 13 biased counterclockwise by the spring 16 as shown in FIG.
Rotates about the shaft 14, the lock pin 15 enters the bent portion of the L-shaped groove 12, and the magazine is locked at a predetermined position in the chassis 6.

When a command for ejecting the magazine is input in the magazine locked state, a lever 13 is driven clockwise around a shaft 14 by a driving mechanism (not shown), and the lock pin 15 moves into the L-shaped groove 12. The magazine lock is released from the bent section. Therefore, the sliding plate 7 slides by the elastic force of the spring 8 applied to the sliding plate 7, and the magazine 1 is ejected toward the magazine insertion port 9.

[0008]

However, in the above-mentioned conventional example, the inserted magazine 1 is loaded into the leaf springs 10a, 10a.
Since the elastic force of b is applied to the front and rear of the magazine 1 via the two rollers 11a and 11b to urge the magazine 1 downward to hold the magazine 1, the number of parts is increased.

The present invention solves the above-mentioned conventional problems, and realizes holding a magazine at a predetermined position with a simple structure.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention sets a tilt angle of a bent piece of a sliding plate urged by a spring to a predetermined angle, thereby ejecting a magazine. The elastic force of the spring is used to urge and hold the magazine downward, and the leaf spring and rollers in the conventional example can be eliminated.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention is
A sliding plate slidably supported by the chassis and driven by the magazine to slide, a spring means for urging the sliding plate in the magazine ejection direction, and a tip of the sliding plate with respect to the sliding plate. A bent spring integrally formed at a predetermined inclination angle, wherein the bent piece is brought into contact with a corner portion of an inserted magazine, and a leaf spring of a conventional example,
The magazine can be pressed against the bottom surface of the chassis by utilizing the elastic force of a spring for ejecting the magazine without using a roller.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. (Embodiment 1) FIG. 1 shows an embodiment of the present invention. In FIG. 1, the same parts as those in the conventional example are designated by the same reference numerals. In FIG. 1, 17 is a sliding plate, and a bending piece 18 inclined at a predetermined angle α (0 ° <α <90 °) with respect to the sliding plate 17 is integrally formed at the tip of the sliding plate 17. Has been formed. Since the elastic force of the spring 8 acts on the sliding plate 17, the biasing force in the ejection direction (A) of the magazine is applied to the magazine 1 by the bending piece 18 that abuts on the corner of the magazine 1. 90 ° to (A)
A different downward (B) biasing force is applied, and this downward (B) biasing force causes the magazine 1 to move to the bottom surface 6 of the chassis 6.
b.

In the above embodiment, when the magazine 1 is inserted through the magazine insertion opening 9 of the chassis 6, the roller 1
1b hits the upper surface of the magazine 1 and urges the magazine 1 downward. When the magazine 1 is further inserted, the tip corner of the magazine 1 hits the bent piece 17a of the sliding plate 17 and the spring 8
The sliding plate 17 is slid backwards against the elastic force of. In the process of inserting the magazine 1, the lock pin 15 enters the groove 12 of the magazine 1. When the magazine 1 is further inserted, the lever 13 biased in the counterclockwise direction by the spring 16 rotates about the shaft 14 as in the conventional example shown in FIG. 5, and the lock pin 15 moves into the L-shaped groove 12. Entering the bent portion, the magazine is locked at a predetermined position in the chassis 6. In the locked state of the magazine, the elastic force of the spring 8 is applied to the magazine 1 in the arrow (A) direction and the arrow (B) direction via the bending piece 18 of the sliding plate 17 to which the elastic force of the spring 8 is applied. The magazine 1 is pressed against the bottom surface 6b of the chassis 6 and held by the component force in the direction of the arrow (B).

When a command for ejecting the magazine is input in the magazine locked state, the lever 13 is driven clockwise around the shaft 14 by the drive mechanism (not shown), and the lock pin 15 is moved to the L-shaped groove 12. The magazine lock is released from the bent section. Therefore, the sliding plate 17 slides by the elastic force of the spring 8 applied to the sliding plate 17, and the magazine 1 is ejected toward the magazine insertion port 9.

[0015]

As described above, according to the present invention, the elastic force of the spring for ejecting the magazine is utilized by setting the inclination angle of the bent piece of the sliding plate biased by the spring to a predetermined angle. Then, the magazine is urged downward and held, and since the elastic force of the spring for ejecting the magazine can be used to press the magazine against the bottom surface of the chassis, the magazine is pressed as in the conventional example. Therefore, it is possible to reduce the number of leaf springs and rollers for simplifying the structure.
