[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail using FIGS. 3 to 7. FIG. 3 shows the overall configuration of the automatic loading/unloading mechanism according to this embodiment.
This mechanism is an ejector 2 that ejects the jacket 1.
and a cam 1 that instructs the ejection operation of the ejector 2.
4, etc., and a spring 5, etc. that attracts the ejector 2. The ejector 2 is guided by a groove 11 provided in the ejector 2 along the rotation axis 10 of the door lever 9, and is movable on the holding plate 3 in the directions of arrows A and B. The ejector 2 is biased in the direction of arrow A by a spring 5, and has the function of biasing the magnetic recording medium 12 enclosed in the jacket 1 in the direction of arrow A and ejecting it from the magnetic storage device. The holding plate 3 also has a latch portion D that is engaged with the tip C portion of the ejector 2 that is moved by the jacket 1 as the jacket 1 enclosing the magnetic recording medium 12 is inserted into the magnetic storage device. The ejector 2 is engaged and held at a predetermined insertion position of the jacket 1. Further, the holding plate 3 is provided with a pin 130 that engages the spring 5 with a guide 13 that supports the rotating shaft 10 of the door lever 9. A door lever 9 is provided on the rotating shaft 10, and a magnetic recording medium 12
After inserting the jacket 1 enclosing the magnetic storage device into the magnetic storage device, the magnetic storage device is made ready for use by rotating the jacket 1 by 90 degrees from the illustrated position. For this reason, a mechanism for clamping the magnetic recording medium 12 and a mechanism for loading the magnetic head against the magnetic recording medium are engaged with the rotating shaft 10, but these mechanisms are omitted in FIG. 3. Furthermore, the rotation axis 10
is provided with a cam 14 that is slightly movable in the axial direction and rotates synchronously with the rotating shaft 10 in the rotational direction, and the cam 14 is moved along the arrow A on the rotating shaft by a spring 15.
is biased in the direction.

Next, the operation of each part will be explained using FIGS. 4 to 8. When inserting the jacket 1 enclosing the recording medium 12 into the magnetic storage device, the jacket 1
First, press the ejector 2 as shown in Figure a. After this, the spring 5 that biases the ejector 2
When the jacket 1 is pushed in further against this, the ejector 2 moves the cam 14 slightly in the axial direction, and then the rear end of the ejector 2 is inserted into the groove 100 provided in the holding plate 3, as shown in FIG. 4b. They are latched by mating. The jacket position at this time is
Corresponding to the position of the second latch described in the Background of the Invention column, and at a position where the center hole (not shown) of the recording medium 1 coincides with the center of the spindle (also not shown) of the magnetic storage device. The dimensions of each part are determined.

In this case, the cam 14 and the like in the direction of arrow P in FIG. 4b become as shown in FIG. 5, and the ejector 2 and the cam 14 come into contact at the tip of the cam 14. The smaller the interference dimension l in FIG.
It is preferable that the discharge timing is delayed. l=2mm, r=
When it is 12 mm, it is appropriate that Θ=l/R=0.17 nad≒10°.

Next, the operation moves to clamping the recording medium 1. As shown in FIG. 6, by rotating the door lever 9, the rotating shaft 10 rotates and the cam 14 also rotates synchronously. Due to this rotation, the cam 14 is disengaged from the ejector 2 and is pushed back onto the rotating shaft 10 toward the door lever 9 by the spring 15. This state is the sixth
The cam 14 is shown in FIG. 7a from the direction of arrow P in the figure.

After using the storage device, when removing the jacket 1 containing the recording medium 12, the door lever 9 is rotated counterclockwise as shown in FIG. 7a. At this time,
The cam 14 also rotates the door lever 9 in synchronization with the rotating shaft 10, and pushes the ejector 2 at the position shown in FIG. 7b.
Due to this force, the ejector 2 moves up in the direction of the arrow R, supporting the fulcrum Q, as shown in FIG. 8, and is released from the latches (D of the holding plate 3 and C of the ejector 2). Therefore, the jacket 1 is ejected from the storage device by the force of the spring 5. this is,
This is the same state as in FIG. 4a.

As described above, the automatic recording medium loading/unloading mechanism according to the present embodiment is provided with the ejector 2 which moves and latches when the jacket 1 is loaded (when inserted) and which is released by rotation of the door lever 9. Since the jacket 1 can be positioned with only one latch position, the jacket can be accurately clamped.

Incidentally, in the above embodiment, the groove portion 10 of the holding plate 3
Although the ejector 2 has been shown to be latched by being fitted with the door lever 9 and to be unlatched about the fulcrum Q by the rotation of the door lever 9, the present invention is not limited thereto.

〔Effect of the invention〕

Since the configuration and operation are as described above, the present invention has the following effects.

(1) The center hole of the recording medium can be accurately positioned and the latch release means and the recording medium ejecting member will not collide even if the clamping operation is mistakenly performed during insertion of the recording medium.

(2) Since the ejector remains in the latched state until the door is about to open, the recording medium can be ejected after the clamp mechanism, head load mechanism, etc. associated with the door lever movement have all moved to the release position.
