Abstract

PURPOSE:To obtain the device capable of easily ejecting a diskette even without strongly pressing a push button by electrically driving the ejection of the diskette. CONSTITUTION:A driving motor 8, a transmission mechanism and a control device 24 are provided in the flexible magnetic disk device. When the diskette is to be ejected, upon pressing of the push button 9 on a front panel, a switch 10 is operated to make the inputtable state of the driving motor 8, and if a diskette ejection inhibit signal is not sent out, the driving motor 8 is started up by the control device 24. A pinion 6 is rotated by starting up the motor 8, and is transmitted to a rack part 5 so that a slide cam is slid, and then the diskette is released by a holder 16 from its gripping. Subsequently, the diskette is ejected by an ejection lever 18 in the direction of X1 (A). Moreover, by cutting off the excitation of the motor 8 at the time of inserting the diskette, the load at the inserting time can be reduced.

Reference numeral 2 is a front panel that covers the front part of the frame 1, 3 is a slide cam that slides in the frame 1 in the X1 direction and the opposite X2 direction, and 9 is a diskette mounted on the slide cam 3 and housed in the flexible magnetic disk device. 7
In order to eject (not shown) from the flexible magnetic disk device in the X1 direction, the operator pushes the push button 9 with his / her finger to push the slide cam 3 from the outside of the front panel 2 in the X2 direction. The operation described later is performed and the diskette 7 is ejected.

Reference numeral 13 is a slide cam spring for pulling the slide cam 3 in the X1 direction, and 14 is a latch lever, which slides on the frame 1 when the slide cam 3 is pushed in the X2 direction and slides on the frame 1 to reach a predetermined position. The lever 14 engages with the slide cam 3 to fix the slide cam 3.
Reference numeral 15 is a latch lever spring for rotating the latch lever 14, and 16 is a holder, which moves up and down along the inclined groove portion 17 of the slide cam 3 by sliding of the slide cam 3 to grip the diskette 7 in the frame 1. 18 is a diskette ejection lever, which engages with the holder 16 and
When the slide cam 3 is disengaged from the slide cam 3, the diskette 7 is pushed out in the X1 direction and ejected to the outside of the front panel 2. Reference numeral 19 is a diskette ejection lever spring for rotating the diskette ejection lever 18, and 20 is a head Ass.
At y, information is read / written from / to the magnetic disk in the diskette 7 mounted on the frame 1 and inserted and fixed at a predetermined position.

Next, the operation will be described. When the diskette 7 is manually inserted through the front panel 2 of the flexible magnetic disk device, the tip of the inserted diskette 7 rotates the latch lever 14 against the restraint by the latch lever spring 15 and thereby the latch lever 1
4 is disengaged from the slide cam 3, and the slide cam spring 13 pulls the slide cam 3 to slide on the frame 1 in the X1 direction. When the slide cam 3 slides in the X1 direction, the inclined groove portion 1 of the slide cam 3
7, the holder 16 descends and holds the diskette 7, and the diskette 7 is securely held at a predetermined position.

To eject the diskette 7, after the insertion operation is completed, the slide cam 3 is slid by pushing the push button 9 mounted on the slide cam 3 from the outside of the front panel 2 with a strong force in the X2 direction with a finger. Contrary to the restraint of the cam spring 13, the slide groove 3 slides on the frame 1 in the X2 direction.
7, the holder 16 ascends, the holder 16 releases the grip of the diskette 7, and when it reaches a predetermined height, the diskette ejection lever 18 operates to push the diskette 7 in the X1 direction and the latch lever. The slide cam 3 is engaged with 14 and the slide cam 3 is fixed, and the diskette ejection operation is completed.

[0006]

Since the conventional flexible magnetic disk device as described above is constructed and operates as described above, in order to eject the diskette 7, the push button is pressed against the suppression of the slide cam spring 13. 9 had to be pressed strongly, a fairly strong force was required, the operation was troublesome, and there was a problem that it was very difficult for people with disabilities to press.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a flexible magnetic disk device capable of ejecting a diskette without pressing it with a strong force.

[0008]

A flexible magnetic disk drive according to the present invention is characterized in that it incorporates an electric diskette ejection mechanism including a drive motor, a transmission mechanism and a controller.

[0009]

In the present invention, by incorporating an electric diskette ejecting mechanism, the motor slides the slide cam to eject the diskette electrically. When the diskette is inserted, the excitation of the motor is turned off to reduce the load when the diskette is inserted. This eliminates the inconvenience of using an electric system.
