Abstract

PURPOSE:To obtain a small size storage device capable of shortening largely a main body of the storage device in the depthwise direction. CONSTITUTION:A floppy disk 2 is loaded under the state of its rerecording prevention discriminating hole 3 protruding out of the storage device main body 1. At this time, detecting light from a light emitting element 4 is reflected by an end surface of the rerecording prevention discriminating hole 3 when this hole is opened, so as to reach a light receiving element 5. The light does not reach it when the rerecording prevention discriminating hole 3 is closed. By this method, even when the rerecording prevention discriminating hole 3 of the floppy disk 2 is protruded out of the storage device main body 1, the detection can be performed by the storage device main body 1. Thus, since the recording medium can be protruded out of the front panel, the depth of the storage device can be shortened. Because of this, a very small size information processing device suitable for carrying can be manufactured by incorporating this storage device.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device built in or externally connected to an information processing device such as a computer or a word processor, and more specifically, it has a state discrimination hole such as a density discrimination hole or a re-recording prevention discrimination hole. The present invention relates to a storage device that records information on a recording medium and reproduces the information.

[0002]

2. Description of the Related Art In recent years, with the miniaturization of information processing devices such as computers and word processors, these devices have been built into them.
Alternatively, there is a demand for miniaturization of externally connected storage devices.

A conventional storage device will be described below. As an example, a storage device using a recording medium having a 3.5-inch floppy type re-recording prevention discrimination hole will be described. FIG. 3A shows a perspective view of a conventional storage device.
(B) is a sectional view of the detection portion of the re-recording prevention discrimination hole. In FIGS. 3A and 3B, 11 is a storage device main body, 2 is a floppy disk in which a magnetic disk (not shown) as a recording medium is incorporated in a case, and 3 is a re-recording prevention provided in the case of the floppy 2. A determination hole, 12 is a re-recording prevention determination switch provided in the storage device body 11,
3 is an eject lever.

The operation of the storage device configured as described above will be described below. First, as shown in the figure, the floppy 2 is inserted into the storage device main body 11. Simultaneously with the insertion of the floppy 2, the floppy 2 is moved downward by a holder (not shown) inside the storage device main body 11. As a result, the magnetic disk inside the floppy 2 is held in a rotatable state (not shown) by bringing the central portion into contact with the spindle (not shown) inside the storage device body 11. Along with this operation, the eject lever 13 projects to the front from the storage device main body 11. At this time, the re-recording determination switch 12 contacts the re-recording prevention determination hole 3 of the floppy 2 inside the storage device main body 11, and whether or not re-recording is possible is detected depending on whether or not the switch 12 is pressed.

[0005]

However, in the above-mentioned structure, since the detection means for the re-recording prevention discrimination hole 3 is formed inside the storage device 11, it is necessary to insert the entire floppy 2 into the storage device main body 11. was there. Therefore, the conventional storage device has a problem that the depth direction of the device body cannot be greatly reduced.

The present invention solves the above problems, and in a storage device for recording / reproducing a recording medium such as a floppy disk, the storage device body is inserted when the recording medium case is inserted into the storage device body. The state determining hole is detected not by the inside of the storage device but by the optical means provided in the storage device or the detection member of the state determination hole which is interlocked with the eject button protruding to the front surface of the storage device body when the recording medium case is inserted. Accordingly, it is an object of the present invention to provide a small-sized storage device capable of projecting the case of the recording medium and greatly reducing the depth direction of the storage device main body.

[0007]

In order to solve the above problems, the storage device of the present invention inserts, mounts and ejects a recording medium having a state discrimination hole such as a density discrimination hole or a re-recording prevention discrimination hole in a case. In addition to the above configuration, when the recording medium is mounted, the state determination hole is located at a position protruding from the storage device main body, and a detector for detecting the open / closed state of the state determination hole is provided.

[0008]

According to the present invention, in the storage device for recording / reproducing a recording medium such as a floppy disk having the above-mentioned structure, the optical state discriminating hole detecting means or the recording medium is inserted when the recording medium case is inserted. By using the state determination hole detection means that works in conjunction with the eject button for ejecting the case, it is possible to construct a compact storage device with the depth direction of the storage device greatly shortened, and if this storage device is incorporated, it is extremely portable. It is possible to manufacture a suitable small-sized information processing device.
