Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a loading device for a disk device such as an optical disk device or a magnetic disk device, which records and reproduces information by rotating a recording medium housed in a cartridge.

Prior Art FIG. 6 shows the main parts of a conventional loading device for a disk device. In FIG. 6, 1 is a cartridge in which a recording medium is stored, 2 is a first carriage having a guide mechanism for guiding the cartridge 1, and this first carriage 2 is connected to a second cartridge.
It is slidably supported by a carriage 3. 4
is a pin provided on the first carriage 2.
The second carriage 3 is supported by a disk device main body (not shown) so as to be slidable in the horizontal and vertical directions. Reference numeral 5 designates a latch which is rotatably supported on the second carriage 3 by a shaft 6, and one end of this latch 5 is engageable with the pin 4. 7 is an electromagnetic solenoid attached to the second carriage 3, and the other end of the latch 5 is connected to a movable iron core 8 of the electromagnetic solenoid 7.
Reference numeral 9 denotes a spring that urges the movable iron core 8 outward.

In FIG. 6, as the cartridge 1 is inserted into the first carriage 2, the first cartridge 2
slides on the second carriage 3 in the right direction.
Further, the first carriage 2 slides to the right together with the cartridge 1 until it reaches a home position, and the pin 4 engages the latch 5, preventing the carriage 2 from returning to the left by a spring (not shown). . When the first carriage 2 reaches the home position, a switch (not shown) is actuated, and the carriage drive mechanism is operated to drive the second carriage 3 to the right and move it vertically to record the cartridge 1. Or set it to the playback position.

When the electromagnetic solenoid 7 is energized in the above-mentioned recording or reproducing state, the movable iron core 8 is attracted and the latch 5 is rotated clockwise. As a result, the latch 5 and the pin 4 are disengaged, and due to the biasing force of the spring. The first carriage 2 moves to the left and is ejected.

Problems to be Solved by the Invention However, since the electromagnetic solenoid 7 is used in the conventional example, there is a problem in that the disk device cannot be made smaller.

The present invention solves the above-mentioned conventional problems and provides a loading device that can be downsized.

Means for Solving the Problems In order to achieve the above object, the present invention includes rotatably supporting a latch release lever on a second carriage, and when the second carriage moves, the latch release lever is A fixing piece is provided by rotating the.

Function The present invention has the above configuration, and when the second carriage moves in a predetermined direction, the latch release lever comes into contact with the fixed piece and is rotated. Rotation of the latch release lever drives the latch and releases the engagement between the latch and the pin.

Embodiment In FIGS. 1 to 5, 2 is a first carriage, 3 is a second carriage, 4 is a pin provided on the first carriage 2, and the first carriage 2 is connected to the second carriage. It can slide left and right on the carriage 3. Further, the second carriage 3 is driven in the left-right direction and the vertical direction by a carriage drive mechanism. 10 is a latch rotatably supported on the second carriage 3 by a shaft 11; 12 is a spring that urges the latch 10 counterclockwise; and 13 is a latch release lever rotatably supported on the shaft 11. and
This latch release lever 13 has a latch release pin 14.
is provided. Reference numeral 15 designates a pin provided on the second carriage 3, and each end of a spring 16 is locked to this pin 15 and the latch release pin 14, respectively. The unlatching lever 13 is held by a spring 16 so that the pin 15, the unlatching pin 14, and the shaft 11 are aligned in a straight line. Reference numeral 17 is a fixing piece disposed close to the side of the second carriage 3, and reference numeral 18 is a regulating plate for regulating rotation of the latch 10.

Next, the operation of the above embodiment will be explained. 1st
In the figure, when a cartridge is inserted into the first carriage 2 from the left, the first carriage 2 moves over the second carriage 3 to the right.
At this time, pin 4 engages latch 10 (FIG. 2).
When the first carriage 2 moves to the right and the pin 4 and latch 10 engage as shown in FIG. moves to the right (Figure 3).
At this time, one end of the latch release lever 13 is connected to the fixing piece 17.
However, the latch release pin 14 does not come into contact with anything. When the second carriage 3 further moves to the right and reaches the position shown in FIG. 4, the movement of the second carriage 3 to the right stops. At this time, the other end of the latch 10 hits the regulating plate 18, and the rotation of the latch 10 is regulated. Here, the second carriage 3 moves in the vertical direction and sets the cartridge held in the first carriage 2 to a position where recording or reproduction is possible.

When recording or reproduction on the recording medium in the cartridge is completed, the second carriage 3 moves vertically and then moves to the left as shown in FIG. At this time, one end of the latch release lever 13 contacts the fixed piece 17 and rotates clockwise, and the latch release pin 14 contacts the latch 10, causing the latch 10 to rotate clockwise. Therefore, the latch 10 and the pin 4 are disengaged, and the first cartridge 2 is moved to the left by the biasing force of the spring, and the cartridge is ejected.

As described above, according to this embodiment, the movement of the second carriage 3 can be used to engage and release the rack 10 and the pin 4, without using an electromagnetic solenoid as in the conventional example. This allows the device to be made smaller.

Effects of the Invention According to the present invention, a latch release mechanism can be configured by simply adding a simple mechanism without overusing an electromagnetic solenoid, making it possible to downsize the device and save power. Become.
