Abstract

PURPOSE:To simplify a reinserting operation by providing a sensor for detecting an inserted cartridge, a spring for pressing the cartridge to an entrance and a lock for holding the cartridge on this side at a prescribed distance from the innermost part. CONSTITUTION:When the disk cartridge 1 is inserted again into a cassette holder 2, the cartridge 1 is held in the holder 2 by engaging the cartridge lock 6 with a groove 1c, whereas the cartridge is pressed in the ejecting direction by a rear spring 8. Consequently, the cartridge 1 is positioned to be slightly moved in the ejecting direction from an operation position of the sensor 7. That is, since the size of a tip part of the lock 6 is specified smaller than the size of the groove 1c, the cartridge 1 is pushed back from a position of contact with the sensor 7 to a position of noncontact with the sensor 7. At the time of reinserting, the cartridge 1 is pushed by larger force than pressing force of the spring 8 so that the cartridge 1 is brought into contact with the sensor 7, and a driving mechanism is operated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc mounting apparatus for holding a disc cartridge containing a medium therein and for conveying the medium to a position where it is fixed to a spindle motor.

[0002]

2. Description of the Related Art FIG. 4 is a plan view showing an example of a conventional disk mounting apparatus.

A conventional disk mounting apparatus for holding a disk cartridge containing a medium inside and transporting the medium to a position where it is fixed to a spindle motor has a disk cartridge 1 inserted therein as shown in FIG. A cassette holder 12, a shutter arm 13 rotatably held at the rear portion of the cassette holder 12, and guided by an arcuate slot 12a provided in the cassette holder 12 to rotate by a predetermined angle. 1
2 is provided with a cartridge lock 4 attached to the left and right side surfaces of the rear portion and engaging with a groove 1c provided in the front side surface of the disk cartridge 1, and a sensor 15 provided on the end surface of the rear portion of the cassette holder 12. There is.

When the disc cartridge 1 is loaded into the disc mounting apparatus having the above-mentioned structure, the disc cartridge 1 is placed with the grooves 1c on both sides facing forward.
It moves in the direction of arrow A, and the disc cartridge 1 is inserted into the cassette holder 12. By this insertion movement of the disc cartridge 1, the shutter arm 13 rotates to open the shutter 1a provided in the disc cartridge 1 to open the medium 1 contained in the disc cartridge 1.
Part of the surface of b is exposed. Disk cartridge 1
When is further inserted deep into the cassette holder 12, the cartridge lock 4 is engaged with the groove 1c to hold the disc cartridge 1 in the cassette holder 12. At this time, the sensor 15 operates by contacting the end surface of the tip of the disc cartridge 1, and operates a drive mechanism (not shown) that conveys the medium 1b together with the disc cartridge 1 to a position where the medium 1b is fixed to a spindle motor (not shown). .

[0005]

In the conventional disk mounting apparatus as described above, the sensor operates at the position where the disk cartridge is held by the cartridge lock to start the carrying movement, so that the disk cartridge is continuously pulled out. When re-inserting, to disconnect the sensor switch, pull out the disk cartridge once from the cassette holder and release the holding by the cartridge lock.
There is a problem that the sensor must be operated by inserting the disk cartridge into the cassette holder again.

DISCLOSURE OF THE INVENTION A disk mounting apparatus of the present invention is a disk mounting apparatus which holds a disk cartridge containing a medium therein and conveys the medium to a position where the medium is fixed to a spindle motor. A sensor for detecting the disc cartridge inserted up to the position, a spring for pressing the inserted disc cartridge toward the entrance, and a position a predetermined distance before the innermost position of the inserted disc cartridge. And a cartridge lock held by.

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

FIG. 1 is a plan view showing an embodiment of the present invention, FIG. 2 is a perspective view showing an example of a disk cartridge held in the embodiment of FIG. 1, and FIG. 1A is a view showing a state in which a shutter is closed. , (B) are diagrams showing a state where the shutter is opened, and FIG. 3 is a sectional view showing an operating state of the embodiment of FIG.

In the embodiment shown in FIG. 1, a cassette holder 2 into which a disc cartridge 1 is inserted and held, and a cassette holder 2 which is rotatably held at a rear portion thereof and is provided in the cassette holder 2 and has an arc-shaped elongated hole. A shutter arm 3 which is guided by 2a to rotate by a predetermined angle, and a cartridge which is attached to the left and right side surfaces of the rear portion of the cassette holder 2 and engages with a groove 1c provided on the side surface of the front portion of the disk cartridge 1. A lock 6, two sensors 7 mounted on the rear end surface of the cassette holder 2 at a predetermined interval, and a rear spring provided on the rear end surface of the cassette holder 2 for urging the disk cartridge 1 to be ejected. 8 and.

When the disc cartridge 1 is loaded into the disc mounting apparatus having the above-mentioned structure, the disc cartridge 1 is placed with the grooves 1c on both sides facing forward.
It moves in the direction of arrow A, and the disc cartridge 1 is inserted into the cassette holder 2. This insertion movement of the disc cartridge 1 causes the shutter arm 3 to rotate,
As shown in FIG. 2, from the closed state of FIG.
The shutter 1a is moved along the guide groove 1e to the opened state of (b) to expose the opening 1d. Since a part of the surface of the medium 1b housed in the disc cartridge 1 is exposed through the opening 1d, it is possible to record / reproduce information on / from the medium 1b. When the disc cartridge 1 is further inserted deeply into the cassette holder 2, the end surface of the tip of the disc cartridge 1 is moved to the sensor 7
The sensor 7 is operated by making contact with. Thereby, the medium 1
A drive mechanism (not shown) that conveys b together with the disc cartridge 1 to a position where it is fixed to a spindle motor (not shown) operates.

When recording / reproducing of information to / from the medium 1b is completed and the disc cartridge 1 is taken out and the disc cartridge 1 is inserted into the cassette holder 2 again,
In the disc cartridge 1, the cartridge lock 6 is held in the cassette holder 2 by engaging with the groove 1c provided in the disc cartridge 1, but the rear spring 8 presses the disc cartridge 1 in the ejecting direction. Therefore, the disc cartridge 1 is at a position slightly moved in the ejecting direction from the operating position of the sensor 7. That is, as shown in FIG. 3, since the size of the tip portion of the cartridge lock 6 is smaller than the size of the groove 1c of the disc cartridge 1, the disc cartridge 1
Is pushed back from a position in contact with the sensor 7 as shown in FIG. 3A to a position in which it does not contact as shown in FIG. 3B. Therefore, when the disc cartridge 1 is reinserted, if the disc cartridge 1 is pushed with a force larger than the pushing force of the rear spring 8, the disc cartridge 1 comes into contact with the sensor 7 and the drive mechanism (not shown) operates.

As shown in FIG. 2, the position where the end surface of the tip of the disk cartridge 1 contacts the sensor 7 is
Since the shutter 1a moves to become either the shutter 1a or the concave portion of the guide groove 1e, by discriminating which of the two sensors 7 comes into contact with the disk cartridge 1, the access surface or the non-access surface of the medium 1b is detected. The distinction can be recognized.

[0013]

As described above, in the disk mounting apparatus of the present invention, the disk cartridge inserted in the cassette holder is held at a position where it is pushed back a little from the position where the sensor is operated to the insertion port. This eliminates the need to pull the disc cartridge out of the cassette holder and then insert it again into the cassette holder during the re-insertion operation. Simply push the disc cartridge back from that position to re-insert it. There is an effect that the operation can be completed.
