Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a floppy disk drive unit for controlling NC lathes and the like.

[Prior art]

Conventional floppy disk drive devices for controlling NC lathes and the like are used near lathes in factories, so they are equipped with a lid 13 as shown in Figure 5 to protect them from dirt and dust and prevent malfunctions. It is proposed in Japanese Utility Model Application Publication No. 61-12640 to put it in the case 14, but when the lid is attached, the operation indicator lamp of the internal floppy disk drive device 6 is hidden by the lid, so it is difficult to check whether it is working or not. There is a drawback that it is not possible to confirm whether the machine is operating or not, and it is not possible to confirm the operating sound in the noisy environment inside the factory.

[Purpose of the invention] In view of the above-mentioned drawbacks, the present invention provides a transparent window on the dust-proof lid so that the operation display section of the floppy disk drive device inside the case can be seen, so that the operating status can be easily confirmed. The purpose of the present invention is to propose a floppy disk drive unit with the following features.

[Structure of the idea]

The present invention provides a floppy disk drive device that is equipped with a floppy disk drive device inside, a keyboard section for selecting a program recorded on the floppy disk, and a dustproof lid that closes the front surface of the floppy disk drive device. In the disk drive unit, a transparent window portion is provided at a position of the dustproof lid facing an operation display portion of the floppy disk drive device.

〔Example〕

Hereinafter, the present invention will be explained with reference to an illustrated embodiment. In FIGS. 1 to 4, a floppy disk drive unit 1 has a dustproof lid 3 supported on one side of a case 2 by a support shaft 10 so as to be openable and closable, and a coil spring 11 stretched between the case 2 and the case 2. A plurality of legs 4 are fixed to the bottom surface of the case 2, so that the dustproof lid 3 is lower than the bottom surface of the case 2 when the lid 3 is opened.

A transparent window portion 5 in which a transparent plate such as acrylic or glass is fitted is provided in the dustproof lid 3 at a position facing the operation display portion 7 of the floppy disk drive device 6 housed in the case 2. The operation display section 7 is configured to be visible through the transparent window section 5.

A keyboard section 8 is provided on one side of the case 2 for selecting a program recorded on a floppy disk.

The structure in which the dustproof lid 3 is supported by the case 2 is such that the shaped levers 9 are fixed to both sides of the dustproof lid 3 as shown in FIG. The case 2 has an elongated hole 1a into which the shaped lever 9 is inserted. Coil spring 11 of the above-mentioned lever 9
The spring hanging hole 9a, into which one end is hung, is formed so that its height is lower than the position of the support shaft 10 when the dustproof lid 3 is opened, as shown in FIG.

The keyboard section 8 may be provided with keys and switches in the case 2 via an insulating member, or
A ready-made keyboard part may be fixed in the recess.

The keyboard section 8 is provided with waterproof packing around it to prevent the intrusion of grinding fluid, etc., and a transparent flexible waterproof rubber sheet or the like is stretched over the top surface.

A handle 12 is provided on the side of the case 2.

When the floppy disk drive unit 1 is configured as described above, the floppy disk drive device 6 housed in the case 2 is dustproofed by the dustproof lid 3 and is protected from dirt, dust, etc., so that malfunctions do not occur. The operation status of the floppy disk drive device 6 can be easily confirmed by viewing the operation display section 7 through the transparent window section 5 when the dustproof lid 3 is closed, and the reliability is improved. It is pulled closed by the coil spring 11, and in the open state, the spring hanging hole 9a is lower than the height of the support shaft 10, so the open state can be maintained without supporting it by hand, and the support shaft 10 and the shaped lever 9 are connected to the case 2. Since it is installed inside the holder, it does not get caught on other objects and has a clean appearance.

[Effect of idea]

Since the present invention is constructed as described above, the floppy disk drive device does not malfunction due to dirt, dust, etc., and reliability is improved. It is possible to provide a floppy disk drive unit which has an excellent practical effect in which the operation display section can be seen through the window section and can be easily confirmed.
