Abstract

PURPOSE:To reduce the titled device at its size by inserting a cartridge into a cartridge guide freely shakably fitted to a carrier under the pop-up state of the carrier, and then engaging the carrier with a frame. CONSTITUTION:Since the carrier 90 is turned from the frame 10 and can select both positions of pop-up state and loading state, the cartridge 44 is positioned on a prescribed position and easily taken out. The cartridge 44 is loaded/unloaded on/from the cartridge guide 110 supported by the carrier so as to be turned and moved in parallel without direct loading/unloading on/from the carrier 90. Since the carrier 90 and the cartridge 110 are separated and independently operated, a head 48 can be prevented from collision with the cartridge 44 at the loading/ unloading of the cartridge 44 in spite of a thin structure and the device can be reduced at its size.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a 7U Tubidisk Dry I, especially a disc drive. The present invention relates to an improved drive for a microphone [1] D-tube disk in which a file disc, which is a recording medium, is housed in a cartridge.

Various types of information recording media are used, including the external memory element of the magnetic disk coater, but magnetic disks are widely used because of their advantages of being able to perform random data transfer and being easy to handle. Used, 1. In recent years, so-called 70-tube disks, in which a magnetic storage layer is coated on one or both sides of a flexible thin plastic substrate, have become commonplace, and compared to earlier hard disks, they are lower in price and have a smaller size in the cylinder. The scope of its use is rapidly increasing due to its numerous advantages, such as the ability to arbitrarily expand storage capacity by replacing disks.

Furthermore, in recent years, information storage discs have been stored in a cartridge made of a plastic hard case, etc., to prevent damage to the recording surface and dust from landing. The so-called cartridge-type microphone [1] was developed as a floppy disk, which was extremely easy to carry and handle, and was used in the field of small computers, especially for personal and home use such as so-called personal computers or microcomputers. It has come to be used in many fields as an external storage device.

According to this cartridge-type Microf[] disc, the disc itself is housed in a hard plastic deck case, and a shutter mechanism built into the case prevents the reading/writing surface from being exposed to the outside. The recording surface of the disk is almost completely protected during handling, and the user can now handle the floppy disk without worrying about damage to the recorded information due to contact with the disk recording surface or foreign matter. Furthermore, it has become possible to mail 70-tube disks in the same way as ordinary mail, making a great contribution to expanding the scope of use for personal use.

In order to take full advantage of the advantages of the cartridge-type micro-floppy disk, we have developed a floppy disk drive device.
't) Various new structures different from the conventional general 8-inch floppy disk drive, IJ, and IJ are required for the floppy disk drive. The goal is to reduce consumption.

1. In other words, computer bodies have become significantly smaller due to recent improvements in LSI chips, etc., despite the increase in processing methods and processing power, and the overall size of computer systems has become smaller than that of keyboards, It is known that the cartridge type microphone is dependent on external storage devices (therefore, the cartridge-type microphone). Q) Make it easier to realize, and furthermore like this <
>11'; It is essential to realize a battery-powered device with low power consumption for the band device.

In the conventional 7II disk drive, the same mechanism as for general large floppy disks is used for the cartridge-type micro-floppy disk mentioned above, and in particular, the method of loading the disk into the drive is mostly from the front. Loading (that is, pushing the cartridge into the mounting opening provided on the front of the loading device along the direction of the disk surface) holds the 5 isk in the operating position, and this structure allows the cartridge to pass through during loading. There is a limit to miniaturization of the device because it requires a path to be secured in advance in the device within the temperature range of °C, and there is a limit to the miniaturization of the device, especially in the thickness direction of the device.
However, the drawback was that it was not possible to achieve significant miniaturization.

Purpose of the invention This defense has been made in view of the above-mentioned conventional problems,
The purpose is to provide a miniaturized floppy disk drive for driving cartridge-type microfloppy disks.
