DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a floppy disk for recording information on magnetic media and reading information as needed.

2. Description of the Related Art In this type of device for inserting and removing magnetic media, the magnetic media insertion means inserts the center portion of the magnetic media inserted through the insertion portion formed in the front panel into a rotary drive unit connected to a motor. By rotating the clamp lever for insertion, the clamp arm is interlocked to press the magnetic media toward the rotation drive section.

Furthermore, in order to improve the operability when taking out the inserted magnetic media, a recess is formed in the insertion portion of the front panel to make it easier to pick up the magnetic media.

Problems to be Solved by the Invention Since magnetic media have low mechanical strength, it is undesirable to apply an unreasonable load when inserting or removing them. First, if the center of the magnetic medium does not coincide with the rotational drive section when it is inserted, there is a risk that the center of the magnetic medium will be damaged when it is pressed by the clamp arm. Therefore, the clamp lever must be operated after confirming whether the magnetic medium is completely inserted, resulting in poor operability.

Furthermore, when taking out the magnetic media, it is necessary to pick up the magnetic panel located in the recess formed in the front panel, which again results in poor operability.

Means for Solving the Problems A front panel is provided with an insertion section into which a magnetic medium is inserted, an inclined surface that interferes with the edge of the magnetic medium inserted into the insertion section, and a stopper opposite the edge. a clamp lever rotatably attached to the front panel so as to rotate to a position where it intersects with the insertion portion; a clamp arm that suppresses the central portion; a receiving portion that abuts the edge on the insertion side of the magnetic media and urges the magnetic media in the ejecting direction; and a receiving portion that engages with a locking protrusion formed on the receiving portion to a trigger that holds the receiving part in the position pushed by the magnetic media; and a release body that is provided integrally with the clamp arm and releases the holding of the receiving part by the trigger when the clamp arm moves in a releasing direction. It consists of:

Function: A sloped part is formed on the clamp lever that is operated to fit the magnetic medium inserted from the insertion part of the front panel into the rotation drive part, and the magnetic medium that is not inserted sufficiently is pressed by the sloped part. The clamp arm automatically moves to the fully inserted position, thereby improving operability during insertion. Also, when removing the magnetic media, the release body provided on the clamp arm operates the trigger, which releases the magnetic media. The holding of the receiving part that urges the medium in the ejecting direction is released, and the magnetic medium is caused to protrude from the insertion part by the receiving part, whereby the magnetic medium can be easily taken out.

Embodiment of the Invention An embodiment of the invention will be described based on the drawings. First, a thin motor 1 is held on a base 2. A rotation drive unit 3 is connected to the motor 1 . And the frame 4 held on the base 2
Leaf springs 5 are screwed onto both sides of one end, and the clamp arm 6 is held while being biased upward by these leaf springs 5. The clamp arm 6 has a positioning body 8 which is located on the same axis as the motor 1 and which fits into a hole formed in the center of the magnetic medium 7. The positioning body 8 is biased toward the motor 1 by a leaf spring 9 and is elasticated. held spontaneously. In addition, the base 2
A front panel 10 is provided on the front edge of the front panel 10, and this front panel 10 has a slit-shaped insertion portion 11 into which the magnetic medium 7 is inserted, a recess 12 into which the magnetic medium 7 is pushed, and a recessed portion 12 for escaping the clamp lever described later. A fan-shaped recess 13 is formed, and a clamp lever 14 is rotatably held around a key position of the fan of this recess 13. A stopper 15 made of a rib that projects into the recess 13 is formed on the inner surface of the clamp lever 14, and an inclined surface 16 is formed on the tip side of the stopper 15.

Next, a shaft 17 that rotates integrally with the clamp lever 14 is rotatably held by a fixedly provided cover 18. Two brackets 19 are fixed to the lower surface of the cover 18, and a set arm 20 is rotatably held on these brackets 19 via a shaft 21a. A receiving plate 22 is bent on the set arm 20 and faces a cam 21 fixed to the shaft 17 of the clamp lever 14. The front end of the clamp arm 6 is held down by the set arm 20. By such means, the clamp arm 6 and the clamp lever 14 are operatively connected.

Further, a support fitting 23 is attached to the frame 4, and a receiving part 24 that contacts the magnetic medium 7 is held in the support fitting 23 so as to be slidable while being biased toward the insertion part 11 by a spring 25. At the same time, the trigger 26 is rotatably held so as to see-saw around a pin 27. This trigger 26 is biased in one direction by a torsion spring 28.
A locking portion 29 that joins to the lower surface of the receiving portion 24 is bent at one end, and a locking protrusion that engages with the locking portion 29 and restricts forward sliding movement is formed on the receiving portion 24. 30 is formed by stamping diagonally toward the front lower part. And the clamp arm 6
A plate spring 31 that is bent in an L shape and hangs down is screwed to the plate spring 31, and a hook piece 32 as a release body that elastically engages and disengages from the edge of the trigger 26 is bent at the lower end of the plate spring 31. has been done.

In such a configuration, the clamp lever 14 is rotated horizontally so as to be parallel to the insertion portion 11 in FIG. Accordingly, the cam 21 rotates and releases the set arm 20. As a result, the clamp arm 6 is rotated upward by the force of the leaf spring 5. This state is shown in FIG. Then, the magnetic medium 7 is inserted through the insertion portion 11 and the clamp lever 14 is turned. If the magnetic medium 7 is not inserted sufficiently, the clamp lever 14 will not rotate. Therefore, the clamp arm 6 also does not rotate. Furthermore, if the center of the magnetic medium 7 is located near the rotation drive unit 3, the clamp lever 14 has the inclined surface 16, so that the magnetic medium 7 can be reliably pushed into the fixed position by the inclined surface 16. Is possible. Further, by turning the clamp lever 14, the cam 21 rotates and pushes the receiving plate 22 of the set arm 20 with its high part, so that the set arm 20 suppresses the floating of the clamp arm 6.
At this time, since the position of the magnetic medium 7 is accurately determined, it will not be damaged by the positioning body 8. Then, when the magnetic medium 7 is inserted, the receiving portion 24 is pushed back as shown in FIG. 5, and the locking portion 29 of the trigger 26 and the locking protrusion 30 engage elastically. When the clamp arm 6 moves downward, the hook piece 32 of the leaf spring 31 elastically engages with the lower edge of the trigger 26.

Recording or reading is performed in this state. When removing the magnetic media 7, use the clamp lever 14.
is rotated parallel to the insertion portion 11, the set arm 20 is released, and the clamp arm 6 is rotated upward by the force of the leaf spring 5 to release the magnetic media 7. At this time, the hook piece 32 of the leaf spring 31 triggers the trigger 26.
In order to pull up one end of the trigger 26, the locking part 2
9 is removed from the locking projection 30, and the receiving portion 24 slides forward by the force of the spring 25, causing the magnetic medium 7 to protrude from the insertion portion 11. In this state, the magnetic media 7 is completely released from the clamp arm 6 and protrudes from the front panel 10, so the magnetic media 7 can be taken out very easily. Damage to the holes can be reliably prevented.

Effects of the Invention Since the present invention is constructed as described above, the clamp lever that is operated to fit the magnetic media inserted from the insertion portion of the front panel into the rotation drive portion has an inclined portion. The magnetic media, which had been insufficiently inserted, can be automatically moved to the fully inserted position by being pressed by the sloped part. This improves the operability during insertion, and also When taking out,
The release body provided on the clamp arm operates the trigger, and along with this operation, the holding part that urges the magnetic media in the ejecting direction is released, and the released receiving part removes the magnetic media from the insertion part. By protruding, the magnetic medium can be easily taken out, and the magnetic medium can be inserted and removed reliably and easily.
