Abstract

PURPOSE:To show clearly the stop position of a lever and also to facilitate a resetting operation of the lever, by preventing the return of the lever which drives a medium chucking mechanism with a lock mechanism and releasing the lock mechanism by means of a push button. CONSTITUTION:A recording medium is loaded through a medium inserting port 5 and a lever 1 which drives a medium chucking mechanism is turned clockwise by 90 deg.. Thus the medium is coupled to a spindle and at the same time the lever 1 is locked by a clock mechanism 3 which is pressed by a plate spring 6. Thus the counterclockwise rotation of the lever 1 is inhibited. If a push button 2 is pushed under such conditions, the mechanism 3 is moved down against the force of the spring 6. Then the lock of the lever 1 is released and the lever 1 is reset to its original position by a resetting spring. In such constitution, the stop position of the lever 1 is shown clearly and the lever 1 can be reset easily.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a magnetic disk device.

[Conventional technology]

Conventionally, in this type of magnetic disk device, after inserting a magnetic recording medium, rotating a lever on the front of the device clockwise will cause the
A medium chuck mechanism is interlocked with this and has a mechanism for coupling the medium chuck to the spindle while being guided and centered by the cylindrical surface of the spindle. This mechanism is released by rotating the lever counterclockwise to return it to its initial position, allowing the medium to be taken in and out.

[Problem that the invention seeks to solve]

The above-mentioned conventional device incorporates a return panel to ensure the return of the lever, and the lever is returned by the force of this return panel from the middle of the return. This return spring is set so that it does not work when the lever is fully rotated clockwise. However, it is unclear whether the lever has been rotated to the point where the return spring acts, and as mentioned above, the lever must be gripped and rotated when loading or unloading the medium, resulting in poor operability. It had the disadvantage of being lacking.

The present invention solves the above-mentioned problems and provides a device that makes the stop position of the lever clear and makes it easy to return the lever.

[Means for solving problems]

The present invention is a magnetic disk device characterized in that it has a locking mechanism for controlling the return of the lever, and a push button for releasing the locking mechanism and releasing the lever is disposed on the front surface of the device.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1(a), (b), and (c), a recording medium insertion slot 5 is provided on the front side of the device, and a lever 1 is rotatably attached. When in the position shown by the chain line, the recording medium can be inserted into the insertion slot 5, and when the lever 1 is rotated clockwise and pushed down to the position shown by the solid line, the medium chuck mechanism is interlocked with the movement of this lever. This configuration is the same as the conventional one.

In the present invention, a return spring 7 is provided to return the lever 1 at the solid line position, and a locking mechanism 3 that locks the lever 1 rotated downward is held by a leaf spring 6.
Press to move the lever back from lever 1? The tongue 2 is placed on the front side 4 of the device.

In FIG. 1, the medium can be inserted when the lever 1 is in the position indicated by the two-dot chain line. After inserting the medium through the medium insertion port 5, when the lever 1 is rotated clockwise and moved to the position indicated by the solid line, the medium is chucked as in the past, but at this time, the locking mechanism 3 is leaf spring 6
It is pushed by the lever 1 against the force of the lever 1, and after sinking, it returns and engages with the back side of the lever 1, thereby preventing the lever 1 from returning counterclockwise. Therefore, the return spring for returning the lever 10 counterclockwise may also operate at the solid line position, which is different from the conventional device. If you press button 2 from this state, 1. The locking mechanism 3 sinks against the force of the leaf spring 6, and the locking mechanism 3 is released from the back side of the lever 1, and the lever 1 is rotated counterclockwise by the return lever 7 and returned to the position indicated by the two-dot chain line. It becomes possible to take in and take out the medium.

〔Effect of the invention〕

As explained above, the present invention clarifies the completion of rotation of the lever in the clockwise direction by providing a locking mechanism for controlling the return of the lever and a push button for releasing the lock disposed on the front side. At the same time, the lever can be returned counterclockwise using a push button, which has the effect of improving the operability of the device.
