Further, a roller 22 is fixed to 0. The roller 22 faces the lower side of the upper frame 10 through an opening formed in the upper frame 10, and has a structure capable of holding the magnetic disk 4 with a pinch roller (not shown). ing.

Incidentally, the reference numeral 23 in FIG. 1 is a bearing.

By the way, a reference numeral 24 is a lever, and the lever 24 is fixed in the middle thereof by a support shaft 25 rotatably supported by a bearing 23. Further, one end of the lever 24 is in contact with the cam surface of the cam 18, and the other end is in contact with a projecting piece 7 a projecting from the tip of the support arm 7.

A cap 26 is fixed to the end of the rotary shaft 13 on the front panel 2 side.

This cap 26 has an opening 2 formed in the front panel 2.
Corresponding to a, so that the front can be rotated using a Phillips or minus driver
V-shaped or -shaped grooves are formed.

Next, the operation of this embodiment configured as described above will be described.

First, when the magnetic disk 4 is inserted from the disk insertion opening 3 of the front panel 2, this magnetic disk is detected by a detection means (not shown), and the signal causes the motor 11 to start rotating.

This rotation is transmitted to the rotary shaft 13 via the gears 12 and 14, the worm gear 15 rotates, and the worm wheel 17 starts rotating.

At the same time, the roller 22 starts rotating via the bevel gears 19 and 21, and the magnetic disk 4 is transferred to a position where it comes into contact with the stoppers S and S.

The cam 18 is rotated by the time the transfer limit is reached, and one end of the lever 24, which has been in contact with the lower cam surface of the cam 18 until now, gradually climbs up on the cam surface at the higher position of the cam 18. .

As a result, the other end of the lever 24 begins to descend, and the protrusion 7a of the support arm 7 begins to be pressed downward.

Then, the center cone 9 descends, clamps the magnetic disk 4 between a spindle (not shown), and the magnetic disk starts rotating.

Along with the lowering of the support arm 7, the head arm 5 engaged with the support arm 7 via the protruding piece 5a also starts to descend, and the magnetic head is brought into contact with the magnetic disk to perform magnetic recording,
Playback starts.

When the clamping by the center cone 9 is completed, the clamp detecting means (not shown) detects this and the rotation of the motor 11 is stopped.

On the other hand, when it is desired to eject the magnetic disk 4 after the magnetic recording and reproduction are completed, a discharge lever (not shown) is pressed, and a motor (not shown) for rotationally driving the magnetic disk stops rotating and at the same time the motor is driven. 11 starts rotating in the opposite direction to that described above.

As a result, the rotating shaft 13 is also rotated in the opposite direction to the above, the worm wheel 17 also starts the reverse rotation via the worm gear 15, and the cam 18 also starts the reverse rotation. Moves from the higher surface of the cam 18 to the lower surface thereof, and the other end of the lever 24 releases the pressing force of the supporting arm 7 against the projecting piece 7a, so that the supporting arm 7 has its free end due to the elastic force of the leaf spring 8. Side rises.

As a result, the clamped state of the magnetic disk 4 by the center cone 9 is eliminated.

At the same time, the roller 22 also starts reverse rotation via the bevel gears 19 and 21, so that the magnetic disk 4 is inserted into the disk insertion slot 3
The magnetic disk is ejected in the direction of.

When the magnetic disk is ejected for a predetermined distance, this is detected by a detection means (not shown), the rotation of the motor 11 is stopped, and the ejection operation of the magnetic disk 4 is completed.

In this state, the magnetic disk 4 is projected from the insertion opening 3 by a predetermined distance, so that the operator can grasp the projected magnetic disk with his finger and take it out of the apparatus completely.

By the way, when the automatic loading clamp and the ejection mechanism of the magnetic disk as described above are out of order for some reason, the user inserts the driver through the opening 2a formed in the front panel 2 and the cap 26 is formed. If the groove and the driver are fitted and the driver is rotated, the rotary shaft 13 is rotated, and the roller 22 can be manually rotated in the direction in which the magnetic disk is ejected.

As a result, the magnetic disk 4 can be taken out of the device completely by turning the driver.

Of course, when the rotary shaft 13 is manually rotated, the cam 18 also rotates and the clamped state of the magnetic disk 4 by the center cone 9 can be released.

In this way, even if the automatic loading, clamping and ejecting mechanism of the magnetic disk fails, the magnetic disk can be manually taken out, so that the conventional troublesome work of removing the cover of the device is completely eliminated. do not need.

Second Embodiment On the other hand, FIG. 3 illustrates another embodiment of the present invention.
In this embodiment, the cap 26 is not attached to the rotary shaft 13 but is fixed to the end of the rotary shaft of the motor 11 on the front panel 2 side. Since the front panel 2 has an opening 2a formed at a position corresponding to the cap 26, if a driver or the like is inserted and the shaft of the motor 11 is rotated from this portion in the same manner as described above, the gear 12 , 14, the rotary shaft 13 can be rotated in the direction of ejecting the magnetic disk 4 in the same manner as described above.

Even if such a structure is adopted, in the same manner as described above, even if the device fails, the magnetic disk can be taken out completely by hand.

Third Embodiment FIG. 4 illustrates a third embodiment of the present invention. In this embodiment, a structure in which the rotary shaft 13 is further projected from the front panel 2 to the front side is adopted. Therefore, if the protruding rotary shaft 13 is pinched and rotated with a finger, the magnetic disk can be manually taken out without the need for a driver or the like.

As is apparent from the above description, according to the present invention, the drive rotating shaft of the loading / unloading mechanism that automatically loads the recording medium such as the magnetic disk to the loading position in the apparatus or automatically ejects the recording medium to the outside of the apparatus. Since it is possible to manually eject the disc by rotating it manually from the outside of
Even if the automatic loading / discharging mechanism or the like fails to automatically eject the disc, the disc can be manually and reliably ejected.
