Abstract

PURPOSE:To take out a magnetic disc manually when an automatic charging and discharging means of the magnetic disc is not worked by rotating the rotary shaft of a driving means manually from a front panel. CONSTITUTION:When the automatic charging clamp and discharging means of the magnetic disc is failed, the user inserts a driver from an aperture part 2a formed on the front panel 2, engages a groove formed on a gap 26 with the driver and turns the driver to rotate the rotary shaft 13, so that a roller 22 can be rotated manually in the discharging direction of the magnetic disc. Consequently, the magnetic disc 4 can be taken out to the outside of the device completely manually by turning the driver. When the rotary shaft 13 is rotated manually, a cam 18 is also rotated and the clamping status of the magnetic disc 4 due to a center cone 9 can be released.

This horn L, 18rJ, has a J shape with the cylinder diagonal, and in the state shown in Figure 1, its -1- plane is a 6z1 plane with one side low and the other side high. There is.

A bevel gear 19 is fixed to the inner end of the rotation +11113, and this bevel gear 19 meshes with a bevel gear 21 fixed to a shaft 20 disposed perpendicular to the rotating shaft 13. , 11. + 20, d, and [) ra 22 are fixed. This opening 22t'' is formed in the upper frame 10 with 11 holes (-opening 1-1 part 11) and 1 part is placed on the ``T'' side of the frame 10, and a pinch roller (not shown) The structure is such that the magnetic disk 4 can be held between the two.

In addition, in FIG. 1, the reference numeral 23 indicates Ire, il.
It is l + uke.

By the way, the reference numeral 24 is a lever, and the lever 24 is fixed in the middle to a bearing 23 and to a support shaft 25 rotatably supported. It's a size.

One end of the lever 24 is connected to the cup surface of the cam 18 with 1 and 2.
A cap 26 is fixed to the end on the tunnel 2 side (the front surface of the rotation shaft 13) at an angle of 4° where the other end is in contact with the protrusion 7al protruding from the tip of the support arm 1. ing.

This cap 26 corresponds to the opening 2a formed in the front panel 2, and has a cross-shaped or Q-shaped shape on the front surface so that it can be rotated using a Phillips or minus screwdriver. Grooves are formed.

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

1. When the magnetic disk 4 is inserted into the disk insertion slot 3 of the front panel 2, this magnetic disk is detected by a detection means (not shown), and the motor 11 is activated by the signal from the detection means (not shown).
starts rotating.

This rotation is caused by the rotation fl'll+ through gear 12.14.
13, the worm gear 15 rotates, and the worm wheel 1 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 contacts the stoppers S and S.

Until this transfer limit is reached, there will be a lot of power! , 18 were being rotated until the end of the lever 24, which had been in contact with the lower horn and surface of the cam 18, gradually came to rest on the cam surface of the cam 18 at a higher position.

As a result, the other end of the lever 24 begins to descend and begins to press the protruding piece 7a of the support arm 7 downward.

When the rotation occurs, the center cone 9 moves downward, clamps the magnetic disk 4 between it and a spindle (not shown), and the magnetic disk starts rotating.

As the support arm 7 descends, the header 5, which is engaged with the support arm 7 via the protruding piece 5a, also begins to descend.
The magnetic head is brought into contact with the magnetic disk and magnetic recording and reproduction are started 3. At the point when the clamping by the center cone 9 is completed, the clamp detecting means (shown in the figure 1) detects this, and the motor 1 rotation is stopped 1
- to do.

On the other hand, after magnetic recording and playback are completed, if you want to eject the disk 4, press the eject lever (not shown) and the motor (1 drive) will rotate the magnetic disk.
(not shown) d, the rotation is stopped, and at the same time the motor 1 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 that described above, and the wheel 17 also starts to reverse rotation via the worm gear 15, and the cam 18 also starts to reverse rotation. One end of the lever 24 moves from the high side to the low side of the cam 18, and the other end of the lever 24 moves against the support arm 7.
In order to release the pressing force exerted on the protruding pieces 1; 1, the support arm 7 is moved to the ground 51 on its free side 9; 11 by the elastic force of the leaf spring 8.

As a result, the clamped state of the center cone 9 (IElt air desk 4) is released.

At the same time, the bevel gears 19 and 21 are activated and the roller 22 also starts to rotate in reverse, so that the magnetic disk 4 is inserted into the disk insertion slot 3.
The magnetic disk is ejected in the direction of r
I get hit.

When the magnetic disk is ejected a predetermined distance, this is detected by a detection means (not shown), the rotation of the motor 11 is stopped, and the operation of the magnetic disk 4 in the first position 1i is completed.

In this state, the magnetic disk 4 protrudes a predetermined distance from the insertion slot 3, so that the operator t can pinch the protruding magnetic disk with his or her fingers and remove it completely from the apparatus.

By the way, if the magnetic disk automatic loading clamp and ejecting mechanism is out of order due to some kind of ejection, the user should: Insert the tri-node from part 1 2a, fit the tri-node with the groove formed in the cap 26, and turn the tri-bar to rotate the rotation 113, and manually move the roller 22 in the direction in which the magnetic disk 441 comes out. It can be rotated or stirred.

This terminology, (Joy Teisuku 4d, Dry Tsuku 4: By turning it, it can be completely manually pushed out of the device 6. Of course, in the case that the rotation Ilη1113 is manually rotated, t;L , force 1118 also rotates and the center
- Clamping of magnetic disk 4 by cone 9 (/11
can be excluded from iQT.

In this way, even if the magnetic disk automatic device, clamp, and ejection mechanism fail, the magnetic disk can be manually removed. There is no need for any troublesome preparation.

Second Embodiment On the other hand, FIG. 3 illustrates an embodiment of a song according to the present invention.
In this embodiment, the cap 26 is not attached to the rotation 13, but is fixed to the end of the rotation shaft of the motor 11 on the front panel 2- side.

Since an opening 2a is formed in the front panel 2 at a position corresponding to the cap 26, if a screwdriver or the like is inserted through this opening in the same manner as described above and the shaft of the motor 11 is rotated, the gear 12 The magnetic disk 4 can be rotated in the direction to eject the magnetic disk 4 in the same way as described above by rotating the rotation 11!l+13 through the rotation angle .14.

Even if such a structure is adopted, in the same way as described above,
Even if the device fails, the magnetic disk can be removed completely manually.

Third Embodiment FIG. 4 explains a third embodiment of the present invention. In this embodiment, a structure is adopted in which the rotating shaft 13 protrudes further from the front panel 2 toward the front side. If the protruding rotation +Il+ 13 is pinched with fingers and rotated, the magnetic disk can be manually removed without using a driver or the like.

As is clear from the above description, according to the present invention, the rotating shaft for automatically loading and unloading magnetic disks is configured so that it can be manually operated from outside the device. Even if the automatic loading/ejecting mechanism or the like fails, the magnetic disk can be reliably removed manually.
