Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium driving device, and more particularly to a medium driving device in which a recording medium in which write protection is turned on / off by sliding a slide portion (notch) in a predetermined direction is inserted. Regarding the device.

[0002]

2. Description of the Related Art Generally, there are some recording media such as floppy disks which are in a write-protected state by sliding a sliding portion in a predetermined direction. If the medium is write-protected, data will not be erased or rewritten due to noise or erroneous operation.
For example, the well-known 3.5-inch magnetic floppy disk corresponds to this.

However, once the write-protected recording medium is inserted into the medium driving device (disk drive device), the recording medium must be taken out from the device in order to cancel the write-protected state. However, there is a drawback that the operation is troublesome. In particular, when the medium is taken out when data remains in the disk cache memory, all the data in the memory is lost.

To solve this drawback, Japanese Patent Laid-Open No. 60-18861 discloses a technique for electrically setting a recording medium inserted in a medium driving device into a write-protected state. In the known technology described in this publication, an electric signal is generated by a changeover switch, and this signal is used as a write protect signal to put it in a write protected state. That is, the inserted recording medium is left as it is, and the write protect signal is generated by the switch operation.

[0005]

In the above-mentioned prior art, since the recording medium itself is not in the write protected state,
When the medium is taken out from the medium driving device, the write protection is released. Then, when the medium is inserted into another medium driving device next time, the write protection is not performed.

Further, since there is no means for releasing the write-protected state, the medium must be taken out from the device in order to release, and when the medium is taken out, all the data in the disk cache memory will be erased. There is a drawback that.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and an object thereof is to provide a medium drive device capable of freely performing write protection and release thereof even when a medium is inserted. Is to provide.

An elongated hole 12 is provided on the side surface of the housing of the device 1, and the switch 2 projects from the hole 12. Then, by sliding the switch 2 in the direction of the arrow Y1 along the elongated hole portion 12, the slide portion for writing protection of the recording medium inserted in the apparatus can be slid.

Here, FIG. 2 is a schematic view showing the main part of the internal structure of the apparatus 1, and the same parts as in FIG. 1 are designated by the same reference numerals. In the figure, a write protection slide portion 24 is provided at the end of the medium 23, and the medium 23 is originally in the write protected state and the write protection is released by sliding the slide portion 24 with a finger or the like. It can be set to any of the states. The apparatus of this embodiment is provided with a transmission portion 21 for transmitting the sliding movement of the switch portion 2 and a connection portion 22 that is connected by gripping the slide portion 24.

The connecting portion 22 is provided with a pair of flexible claw portions which will be described later. The positions of the pair of claw portions and the slide portion 2 are provided.
When the position of 4 and the position of 4 are substantially the same, both are gripped and connected. If the switch portion 2 is slid in the direction of the arrow Y1 in this connected state, the medium 23 remains in the state of being inserted into the device and is in either the write protected state or the write protected released state. You can set the crab.

FIG. 3 shows an enlarged view of the broken line portion H in FIG. 2, and the same parts as those in FIG. 2 are designated by the same reference numerals. FIG. 11A shows a state immediately after the medium is inserted into the apparatus, and the claw portions 31 and 32 of the connection portion 22 are not connected to the slide portion 24. Here, the claw portions 31 and 32 are both made of a flexible material (for example,
It is made of resin or metal) and its tip portion is slightly inclined inward as shown. With this configuration, even if the position of the connecting portion 22 and the position of the sliding portion 24 do not match when the medium is inserted, smooth operation can be achieved by sliding the switch 2 in the direction of the arrow Y2. It is possible to move the connecting portion 22 to the connecting portion 22 and the sliding portion 24 without any problem.
