Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a medium exchange type disk device, and particularly to its structure.

In conventional devices of this type, such as floppy disk devices, the pivot point of the operating lever, including the arm to which the collet for clamping the medium is attached, is located at the farthest end of the device, so the operating distance of the operating lever is limited. Moreover, since these mechanisms were provided on one side with respect to the medium, the width of the apparatus itself became large.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such drawbacks of conventional floppy disk devices and to provide a floppy disk device with good operability.

According to the present invention, there is provided an insertion slot into which a disk medium is inserted, a collet that holds the central portion of the inserted disk medium, and a rotating shaft provided between the insertion slot and the central portion of the disk medium. A collector holding plate that is rotatably held around the disk, and a shaft that engages with the collector holding plate and is provided closer to the insertion opening than the center of the disk medium is the center of rotation, and a part of the disk medium protrudes outside the insertion opening. According to the present invention, there is obtained a disk device characterized in that it has a control lever.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a floppy disk device 10 according to an embodiment of the present invention. Referring to FIG. 1, the floppy disk device 10 of this embodiment includes an insertion opening 12 into which a floppy disk 11 is inserted, and an insertion opening 12 into which a floppy disk 11 is inserted.
2, a collet 15 that holds the floppy disk 11, and an arm 14 that connects the operating lever 13 and the collet 15. The operating lever 13 is provided on the left side of the insertion opening 12 of the floppy disk device 10 (as shown in FIG. 1). The arm 24 is the insertion port 12
the first arm 14a provided on the left side of the
, a second arm 14b provided on the right side with respect to the insertion port 12, and a third arm 14c that connects the first arm 14a and the second arm 14b. Reference numeral 14c denotes a first arm 14a and a second arm 14b attached to both sides 11a and 11b of the floppy disk 11 so as to sandwich the floppy disk 11 therebetween. is provided with a rotation center shaft 16, which allows the arm 14 to swing. The collet 15 is attached to one end of a collet holding plate 17 which is constructed of a spring. The other end of the collet holding plate 17 is fixed to the device main body 10, and the collet 15
The floppy disk 11 is configured to act with the shaft 18 as a fulcrum so that the spring is generated in the direction away from the floppy disk 11. This holding plate 17 contacts the second arm 14b of the arm 14 between the mounting position of the collet 15 and the fixed position of the collet holding plate 17, and holds the floppy disk by counterclockwise rotation of the arm 14. It is configured to provide spring force.

FIG. 2 shows the operating lever in this embodiment in an open state. Referring to FIG. 2, the operating lever 1
3 is moved in the direction A', the arm 14 rotates clockwise about the rotation center shaft 16, and in conjunction with this, the collet holding plate 17 rotates the collet 15 in the direction of arrow B due to its spring force. be moved. This allows the collet 15 to remove the floppy disk.

Next, FIG. 3 shows a state in which the operating lever in this embodiment is closed. Referring to FIG. 3, when the operating lever 13 moves in the direction A, the arm 1
4 is rotated counterclockwise about the rotation center shaft 16 as a fulcrum. The second arm 14b of the arm 14 rotates the collet holding plate 17 about the fulcrum 18 in the direction of arrow B'. Further, as the arm 14 rotates, the second arm 14b of the arm 14 presses the back of the collet holding plate 17 in a counterclockwise direction. The spring force of the collet holding plate 17 is generated using the point where it contacts the second arm 14b as a fulcrum to completely hold the floppy disk.

In this way, in this floppy disk device, the collet 15 and the operating lever 13 are disposed to sandwich the floppy disk 11 (floppy disk insertion opening 12), so the movement range of the collet 15 is a distance a, and the operation The movement range of the lever 13 is a distance b. The width of this device is the floppy disk insertion slot 1
In contrast to 2, on the collect side, approximately the distance a is sufficient;
Furthermore, the distance b on the operating lever side is smaller than the size of other parts attached to the device, such as the motor that drives the floppy disk, so it is not necessary to consider this distance b as the width of the device.

Therefore, the device width of the present device can be sufficiently reduced, making it possible to reduce the width to approximately half that of conventional devices.

As explained above, the present invention has the effect of making the force relationship between the operating lever and the collector exactly the same as the conventional one, improving operability, and making it possible to reduce the size of the disk device.
