Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock mechanism for a cartridge type hard disk drive, and more particularly to a mechanism for preventing a cartridge type hard disk drive from being accidentally removed from a terminal device and an eject mechanism.

[0002]

2. Description of the Related Art As shown in FIG. 2, a lock mechanism of a conventional cartridge type hard disk drive employs a lock mechanism using a pull solenoid, and a terminal device 15
By disconnecting the power of the lock pin 16, the lock pin 16 is released, and the cartridge type hard disk drive 1 can be connected to the connector 2 by being inserted into the terminal device 15. Further, when the power is turned on, the cartridge type hard disk drive 1 is fixed by the locking pin 16 so that the cartridge type hard disk drive 1 is not accidentally removed from the terminal device 15 (see Japanese Patent Laid-Open No. 1-192051). ).

[0003]

In the prior art, when the cartridge type hard disk drive is locked to the terminal device, the lock mechanism is always energized from the time the power is turned on to the time when the power is turned off. Moreover, there is a drawback that heat is generated.

Therefore, the present invention is intended to improve the drawbacks of the above-mentioned conventional techniques and to reduce power consumption and heat generation when locking a cartridge type hard disk drive to a terminal device. .

[0005]

The present invention adopts the following means in order to solve the above problems.

(1) The lock member is provided with a habit so that the cartridge type hard disk drive is engaged with the eject mechanism for withdrawing from the terminal device, and when the lock member is released from the eject mechanism, the sensor mechanism is operated to turn on the power supply. Locking mechanism for cartridge type hard disk drive that warns that it is in the closed state.

(2) The eject mechanism is a detachable member of a cartridge type hard disk drive, an intermediary member rotatably connected to the detachable member by a pin, and rotatable about a rotation control pin, and an intermediary member. The lock mechanism for a cartridge type hard disk drive according to (1) above, which comprises a slide member rotatably connected to the member by a pin.

(3) The lock mechanism for a cartridge type hard disk drive according to (1), wherein the sensor mechanism detects the lock member and issues a warning using a cable, an amplifier and a speaker.

(4) The lock mechanism for a cartridge type hard disk drive according to (1), wherein the sensor mechanism detects the lock member and displays a warning on a display.

[0010]

Embodiments of the present invention will be described with reference to the drawings.

One embodiment of the lock mechanism of the cartridge type hard disk drive of the present invention is shown in FIGS.
It shows in (b). The lock mechanism of the cartridge type hard disk drive of the present invention is the cartridge type hard disk drive 1 connected to the connector 2 in the terminal device.
It has a mechanism for preventing accidental removal from the connector 2 and an eject mechanism for removing the cartridge type hard disk drive 1 from the connector 2.

When the lock lever 6 is rotated counterclockwise while the terminal device is in the energized state, the tip of the lock lever 6 energizes the sensor 7, and at that time, the control signal causes the cable 9 to move. A signal for audio output (audio signal) that is sent to the amplifier 10 that controls the operation of the speaker 8 through
Is converted to. The converted audio signal is sent from the amplifier 10 through the cable 11 to the speaker 8, and the speaker 8
A warning sound such as a buzzer sound is output from. If the terminal device is not energized, the amplifier 1
Since the control signal from the sensor 7 is not converted into a sound signal by the amplifier 10 by stopping the power supply to 0 and keeping it in an insulated state, no warning sound is output from the speaker 8.

Further, in the above embodiment, the warning is given from the speaker, but the warning can be displayed on the display instead of the speaker.

Next, an embodiment of the eject mechanism will be described. When the accidental removal prevention mechanism is working,
As shown in (b), the lock lever 6 is the slide lever 5
And the eject mechanism does not work. The lock lever 6 is given the habit of always engaging with the slide lever 5 by a spring or the like. Here, the lock lever 6 is rotated counterclockwise to make the slide lever 5 in a free state. Then, the slide lever 5 is pushed rightward in FIG. The slide lever 5 is rotatably connected to the intermediary lever 4 by a pin 14. The intermediary lever 4 can rotate around a rotation control pin 12, and the pin 13 connects with the detachable lever 3 of the cartridge type hard disk drive. It is rotatably connected. At this time, the intermediary lever 4 rotates counterclockwise about the rotation control pin 12, and the attaching / detaching lever 3 of the cartridge type hard disk drive 1 that interlocks with the intermediary lever 4 is left in FIG. 1B. The cartridge type hard disk drive 1 is removed from the connector 2.

When the cartridge type hard disk drive 1 is attached to the connector 2 in the terminal device, the attachment / detachment lever 3 of the cartridge type hard disk drive 1 is used.
Is pushed by the cartridge type hard disk drive 1. At this time, the intermediary lever 4 and the slide lever 5 are interlocked, and the intermediary lever 4 rotates clockwise around the rotation control pin 12, and accordingly the slide lever 5 also moves.
(B) Moves to the left. But in this state,
Since the slide lever 5 freely operates, the eject mechanism malfunctions when the power of the terminal device is turned on, and the cartridge type hard disk drive 1 is detached from the connector 2. In order to prevent this, the lock lever 6 is rotated clockwise and the slide lever 5 is pressed to prevent the cartridge type hard disk drive 1 from being pulled out from the connector 2.

Thus, it is possible to prevent the cartridge type hard disk drive 1 from being unlocked by mistake when the power of the terminal device is turned on, and to prevent the hard disk drive from being accidentally removed due to a malfunction of the eject mechanism and an erroneous operation.

[0017]

As described above, according to the present invention, in order to prevent the cartridge type hard disk drive from being mistakenly removed from the terminal device, the power consumption of the cartridge type hard disk drive is reduced in comparison with the conventional technology which continuously consumes the power from the time the power is turned on to the time the power is turned off. This is convenient in terms of thermal design of the terminal device because it saves heat and reduces the amount of heat generation.

Further, according to the present invention, since the sensor mechanism is associated with the erroneous removal preventing mechanism of the cartridge type hard disk drive from the terminal device, a warning is given when the power is on when the erroneous removal preventing mechanism is released. Is.
