Abstract

PROBLEM TO BE SOLVED: To smoothly eject a disk cartridge by an auto eject mechanism. SOLUTION: The auto eject mechanism 24 of the recording medium loading device 11 consists of a rising part 52 formed on the left end part 14f of the slider 14, a rotor 56 having an eccentric pin 54 that is driven in contact with the rising part 52, and a motor 58 for rotating the rotor 56. In addition, the rising part 52 is situated on the extension obliquely against the insert/eject direction (A, B directions) of the disk cartridge. Consequently, when the eccentric pin 54 pressurizes the rising part 52 of the slider 14 in the eject direction (B direction) through the rotation of the rotor 56, the rising part 52 is imparted by force Fa in the B direction and force Fb in the C direction. As a result, the force for rotating counterclockwise acts on the slider 14, enabling the force for rotating clockwise to be cancelled.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium mounting apparatus, and more particularly to a recording medium mounting apparatus configured to automatically eject a recording medium on which writing or reading has been completed.

[0002]

2. Description of the Related Art For example, an electronic device such as a personal computer or a word processor is equipped with a magnetic disk device as a means for recording information. When a disk cartridge as a recording medium is mounted in the magnetic disk device, the magnetic disk accommodated in the disk cartridge is driven to rotate, and the magnetic head slides on the magnetic disk to perform magnetic recording and reproduction.

In the magnetic disk drive as described above, a disk holder into which a disk cartridge is inserted, and a cartridge insertion / eject position (second position) to a cartridge mounting position (first position) by a disk cartridge insertion operation. Position), and a recording medium mounting device for moving the disk holder from the recording medium unloading position to the recording medium loading position in conjunction with the sliding of the slider.

Generally, in a conventional magnetic disk drive, a disk holder is moved from a recording medium loading position to a recording medium unloading position by pressing an eject button attached to a front end of a slider, and a disk cartridge is ejected. It is configured to: However, as described above, conventionally, since the disk cartridge is ejected by the pressing operation of the eject button, for example, the disk cartridge is ejected even if the ejecting operation is performed while the magnetic head is writing or reading. There was a problem.

[0005] Therefore, a recording medium mounting apparatus employing an auto-ejection mechanism for ejecting a disk cartridge by a driving force of a motor by abolishing a mechanical ejection mechanism using a pressing force of an ejection button as a driving source is being developed. . Therefore, in a recording medium mounting device incorporating an auto-eject mechanism, even if an instruction to eject a disk cartridge is issued, the eject operation is not performed until writing or reading by the magnetic head is completed.

Here, a specific example of a recording medium mounting device incorporating an auto-eject mechanism will be described with reference to FIG. As shown in FIG. 15, the magnetic disk drive 1 has a frame 4 in which a disk holder 2 into which a disk cartridge (not shown) is inserted, and a slider 3 which slides up and down the disk holder 2 by sliding back and forth. Attached to. The slider 3 is slidably provided on the frame 4 in the directions A and B. Then, the latch lever 5 rotates clockwise by the insertion operation of the disk cartridge, and the disk cartridge shutter (not shown)
Is opened and the lock of the slider 3 is released.

For this reason, the slider 3 urged in the direction A by the spring force of the coil spring 3b slides in the direction A to lower the holder 2 from the recording medium unloading position to the recording medium loading position. Thus, the disc cartridge inserted into the holder 2 is mounted on the turntable. When the ejection signal is output, the motor (not shown) of the automatic ejection mechanism 7 drives the gear 7.
is driven to rotate, and the eject slider 7b having the rack with which the gear 7a meshes is driven in the B direction. As a result, the rising portion 7c of the eject slider 7b comes into contact with the rising portion 3a provided at the left end of the slider 3, and presses in the B direction. In FIG. 15, since the latch lever 5 and the like are arranged on the right side of the frame 4, the auto-ejection mechanism 7 is arranged on the left side of the frame 4.

For this reason, the slider 3 slides in the direction B to raise the holder 2 from the recording medium loading position to the recording medium unloading position. When the slider 3 slides in the B direction,
The latch on the latch lever 5 is released. As a result, the latch lever 5 rotates counterclockwise by the spring force of the torsion spring 6 and pushes the disk cartridge in the disk holder 2 in the ejecting direction.

However, in the recording medium mounting apparatus having the above structure, the rising portion 7c of the eject slider 7b is moved by the force F1 at the rising portion 3a provided at the left end of the slider 3 during the auto-eject operation. In the direction B, the spring force F3 of the damper spring 8b provided on the left side of the slider 3 acts on the left side of the slider 3 via the damper plate 8a in the direction B, and the spring force F4 of the coil spring 3b causes the spring force F4 to move in the direction A. Because it is energized,
The balance of the forces F1 to F4 acting on the slider 3 shifts to the left of the slider 3, and a moment is generated to turn the slider 3 clockwise.

As a result, both sides of the slider 3 are pressed against the side walls of the frame 4 to increase the sliding resistance, so that the ejecting operation may not be performed smoothly.

It comprises a rotating body 56 and a motor 58 for rotating the rotating body 56.

The rising portion 52 extends obliquely with respect to the insertion / ejection directions (A and B directions) and the C and D directions of the disk cartridge. Therefore, when the eccentric pin 54 presses the rising portion 52 of the slider 14 in the ejecting direction (B direction) by the rotation of the rotating body 56 as described later, the rising portion 52 exerts a force Fa in the B direction and a force Fb in the C direction. Are given. As a result, a force for rotating the slider 14 in the counterclockwise direction acts on the slider 14, and the spring force Fd of the damper spring 32 of the damper mechanism 26 and the spring force Fe of the coil spring 48 for urging the slider 14 in the A direction. The action can be used to cancel the force for turning clockwise.

Therefore, the slider 14 is mounted on the frame 16
Is prevented from being pressed against the side wall, and sliding resistance is reduced. Therefore, the slider 14 can slide smoothly in the ejection direction (B direction).

Since 2e is fitted, the sliding operation of the slider 14 drives the engagement pin 12e along the inclined groove 14d.
Therefore, the slider 14 is moved from the cartridge mounting position (first position) to B
When the disk holder 12 slides in the direction to reach the cartridge insertion / ejection position (second position), the disk holder 12 moves up to the recording medium unload position.

When the slider 14 slides in the direction A from the cartridge insertion / ejection position (second position) to the cartridge mounting position (first position) by the eject operation, the disk holder 12 loads the recording medium. Descend to position. Therefore, the recording medium transport mechanism is constituted by the disk holder 12 and the slider 14. Here, the auto-eject mechanism 24 constituting a main part of the present invention
Will be described.

FIG. 8 is an enlarged plan view showing the operation state of the auto-eject mechanism 24 before the disk cartridge is inserted. FIG. 9 is an enlarged plan view showing an operation state when a disc cartridge is inserted. FIG. 10 is an enlarged plan view showing an operation state at the time of ejection. FIG. 11 is an enlarged plan view showing the operation state at the latch release setting position. FIG. 12 is an enlarged plan view showing a state where the slider 14 has moved to the innermost position.

As shown in FIG. 8, the auto-eject mechanism 24 before inserting the disk cartridge
4 slides in the direction B, the rising portion 52 formed on the left end portion 14f of the slider 14
It is in the standby position, which is separated from the rotating body 56 by the diameter of the rotating body 56 in the direction. The standby position of the eccentric pin 54 is set on the D direction side with respect to the imaginary lines in the A and B directions passing through the rotation center of the rotating body 56 in order to increase the movement stroke of the slider 14 by the auto-ejection mechanism 24 as described later. I have.

The rising portion 52 is formed so as to extend obliquely at a predetermined angle θ with respect to the C and D directions perpendicular to the sliding direction (A and B directions) of the slider 14. Next, when inserting the disk cartridge, the latch lever 44 is rotated clockwise by the operation of inserting the disk cartridge into the disk holder 12 as described above, and the insertion of the disk cartridge is completed and the locking of the slider 14 is released. Then, the slider 14 slides in the B direction. Therefore, as shown in FIG. 9, the rising portion 52 provided at the left end of the slider 14 approaches the eccentric pin 54 of the auto-ejection mechanism 24. In this state, the eccentric pin 54
Are not in contact with the rising portion 52 and are separated through the gap A.

Therefore, even when the disk cartridge is inserted into the disk holder 12, the rising portion 52 of the slider 14 does not collide with the eccentric pin 54. Next, the operation in the case where the disk cartridge mounted at the mounting position together with the disk holder 12 is ejected will be described. When the eject button 88 is pressed in a state where writing or reading to or from the magnetic disk accommodated in the disk cartridge is completed, as shown in FIG. 10, an auto-eject mechanism is provided by a control signal from a control circuit (not shown). 24 is driven to rotate and the eccentric pin 54 is rotated.
Is driven to rotate clockwise. Thus, the eccentric pin 54 rotates to a position where the eccentric pin 54 contacts the rising portion 52 together with the rotation of the rotating body 56.

The rising portion 52 is formed obliquely at an angle θ with respect to the C and D directions perpendicular to the sliding direction (A and B directions). Therefore, the eccentric pin 54 presses the rising portion 52 with a force F in a diagonal left direction perpendicular to the rising portion 52 with respect to the sliding direction (A and B directions) of the slider 14. As a result, a pressing force Fy in the B direction and a pressing force Fx in the C direction act on the rising portion 52. Therefore, the slider 14
Is the pressing force Fx in the C direction so as to cancel the moment of turning in the clockwise direction by the pressing force Fx.
Act, the slider slides in the ejecting direction due to the pressing force Fy in the B direction.

The disk holder 12 moves up from the recording medium loading position to the recording medium unloading position in conjunction with the sliding movement of the slider 14 in the ejecting direction. Further, when the rotating body 56 rotates clockwise, as shown in FIG. 11, the slider 14 reaches the latch release position where the latch 14 is released from the latch lever 44. Therefore, the latch lever 44 rotates counterclockwise by the spring force of the coil spring 48 and pushes the disk cartridge in the disk holder 12 in the ejecting direction (A direction).

Further, in this latch release state, the eccentric pin 54 moves in the directions B and D while
Will be pressed. In this eject operation state,
The eccentric pin 54 presses the rising portion 52 obliquely to the left with respect to the sliding direction (A and B directions) of the slider 14. As a result, the pressing force Fy in the B direction is applied to the rising portion 52.
And the pressing force Fx in the direction C act. Therefore, the slider 14 is slid in the ejecting direction by the pressing force Fy in the B direction because the pressing force Fx in the C direction acts so as to cancel the moment to rotate clockwise by the pressing force Fx. I do.

The rising portion 52 is formed so as to extend obliquely at an angle θ with respect to the directions C and D perpendicular to the sliding directions (A and B directions), but the eccentric pin 54 rotates clockwise. As a result, the pressing force Fx in the direction D decreases, and the force for rotating the slider 14 in the counterclockwise direction gradually decreases.
However, the slider 14 is pressed in the direction B and slides in the ejecting direction while the force for rotating the slider 14 in the clockwise direction is kept small.

Further, when the rotating body 56 rotates clockwise, as shown in FIG. 12, the rotating body 56 slides in the direction B from the latch release position. The sliding distance B is an overstroke from the latch release position, and the slider 14 is locked at the rising portion 14g by the latching portion 44b of the latch lever 44, and returns to the state before the disk cartridge is inserted. At this time, the pressing force F of the eccentric pin 54 against the rising portion 52 acts substantially in the direction B, but separates from the rising portion 52 as the eccentric pin 54 rotates clockwise. Thereafter, the eccentric pin 54 further rotates clockwise and returns to the above-described standby position shown in FIG.

The auto-eject mechanism 24 includes a rotating body 56
, The standby (stop) position and the moving direction of the auto-eject mechanism 24 can be reduced to one, thereby facilitating the control of the auto-eject mechanism 24. did it.
FIG. 13 is an enlarged plan view showing a state where the eccentric pin 54 has moved the slider 14 to the eject position. Also,
FIG. 14 is a plan view showing a state in which the eccentric pin 54 has rotated to the standby position.

In FIG. 13, since the rising portion 52 is formed at an angle θ with respect to the C and D directions perpendicular to the sliding direction (A and B directions), the rising portion 52 is moved in the C and D directions. The stroke in the B direction is longer than when the extending direction (θ = 0) is set. That is, the eccentric pin 54
