Abstract

PURPOSE:To securely carry an FD and to prevent dust and dirt from being produced by coupling an FD feed hook with the hole of an FD cartridge and putting the FD in and out of a magazine and an FD drive. CONSTITUTION:When a flexible disk (FD) access instruction is sent out, an FD carrier 8 and the FD feeder 3 move to the place of a target FD 1. Then the FD feeder hook 9 moves forth with the driving force of a feeder motor 10 to insert the FD into the magazine 2 and then engages with the hole of the cartridge of the FD 1. Then the hook 9 moves back to take the FD 1 out and the FD 1 is carried to the FD drive 3 while held by the feeder 3 by the movement of the carrier 8 and inserted. Thus, the FD feeder 3 is so constituted as to put the FD 1 in and out of the magazine 2 and FD drive 4 by hooking the hole of the FD cartridge by the hook 9, and consequently, the FD 1 is securely carried and dust and dirt are prevented from being produced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a flexible disk that is used in OA equipment, AV equipment, electronic meter ΔPI equipment, etc., and is capable of storing and searching large amounts of various data. It concerns autochangers.

[Prior Art] An example of a conventional flexible disk autochanger using a large number of flexible disks as recording media is shown in FIGS. 3 and 4.

3 and 4, 1 is a flexible disk (hereinafter abbreviated as FD), 2 is a magazine, 3 is a flexible disk feeder (hereinafter abbreviated as FD feeder), 4 is a flexible disk drive (hereinafter abbreviated as FDD), 5
is the motor for moving the carrier, 6.6' is the guide shaft,
7 is a ball screw, 8 is a flexible disc carrier (
(hereinafter abbreviated as FD carrier), 10 is a feeder motor, 1
3.13' is a flexible disc feed belt (
(hereinafter abbreviated as FD feed belt).

In FIG. 3, several dozen FDs are stored in the magazine 2, the FD feeder 3' installed on the FD carrier 8 is positioned by the carrier moving motor 5, and the FD The FD field belt 13°13' of the feeder 3' allows the separately provided FD
It is drawn into D4 and data is read and written.

[Problem to be solved by the invention] In the conventional case, FDl is FD field belt 13□ 1
3' and is conveyed by friction between the belt 13, 13' and the FDl cartridge, which causes the problem that it slips and cannot be conveyed.

In addition, in the conventional case, when the FDI is transported, the belt 13, 13' rubs the FDI cartridge every time it is transported, generating dirt and dust that enters the cartridge and loses data on the FDI and the FDD 4. There was a problem that the head of the machine could be damaged.

Furthermore, since the rotation time control of the feeder motor 10 cannot be used as a means to control the conveyance operation of the FDl, an extra detector must be added to detect the position of the FDl, which increases costs. There was a problem.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a flexible disk autochanger that can transport FDs reliably, does not generate dirt or dust, and is inexpensive.

[Means for Solving the Problems] According to the present invention, a magazine capable of storing a plurality of flexible disks, a flexible disk drive that performs recording and reproducing of the flexible disk, and a space between the magazine and the flexible disk drive. A flexible disk autochanger including a carrier for moving a flexible disk, and a flexible disk feeder attached to the carrier for loading and unloading the flexible disk into the magazine and the flexible disk drive, the flexible disk feeder comprising:
A flexible disk characterized in that it has a flexible disk feed hook that engages with a hole provided in the cartridge of the flexible disk and is provided so as to be retractable in a direction parallel to the direction in which the flexible disk is taken in and taken out. You get an autochanger.

[Function] In the case of the flexible disk autochanger of the present invention, the FD feed hook is connected to the hole of the cartridge of the FD and the FD is inserted into and taken out from the magazine and the FDD, so that the FD is reliably taken in and taken out. Further, when inserting or removing an FD, the FD cartridge is not rubbed as in the conventional case, so no dirt or dust is generated.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a flexible disk autochanger according to an embodiment of the present invention, FIG. 2 is a perspective view of the FD feeder section of the flexible disk autochanger of the same embodiment, and FIG. 3 is a perspective view of the main parts of the FD feeder. The plan view and FIG. 4 are front views of the same essential parts.

In Figures 1 and 2, 1 is an FD, 2 is a magazine,
3 is the FD feeder, 4 is the FDD, 5 is the motor for moving the carrier, 6.6' is the guide shaft, 8 is the FD carrier,
9 is the FD feed hook, 10 is the feeder motor, 31
is the timing belt, 32 is the FD feed link, 33
is the FD feed arm, 34 is the feeder guide roller,
35 is a worm gear, and 36 is a worm wheel.

In FIG. 1, a magazine 2 can store a plurality of FDIs, and the FDs in the magazine 2 can be replaced one by one. It is also possible to convert FDs in magazine units.

The FDD 4 is fixedly installed at any location within the device.

The FD feeder 3 is mounted on the FD carrier 8.

This FD feeder 3 is as shown in FIGS. 3 and 4.
FD feed hook 9, FD feed link 32, FD
It has a feed arm 33 and a feeder guide roller 34. The tip protrusion of the FD feed hook 9 is
a hole (not shown) formed in the cartridge.

The FD carrier 8 is movably mounted on the guide shaft 6.6' and connected to a timing belt 31 mounted on the carrier movement motor 5.

A feeder motor 10 is provided at the bottom of the carrier 8. The driving force of the feeder motor 10 is transmitted to the FD feed arm 33 via a worm gear 35 and a worm wheel 36. When the feeder motor 10 is driven, this driving force is transmitted to the FD feed arm 33 via the worm gear 35 and the worm wheel 36, causing the FD feed arm 33 to swing. This rocking motion is caused by the FD feed link 3
This swinging movement causes the FD feed hook 9 to move in and out in a direction parallel to the direction in which the FD1 is taken in and taken out of the magazine 2 and the FDD 4.

Next, the operation of this embodiment will be explained.

First, when an FD access command is issued from the host computer side, the FD carrier 8 and FD feeder 3 are driven by the timing belt 31 and move to the target FDI location. Next, the feeder motor 10 is driven, and by this driving force, the FD feed hook 9 is advanced and inserted into the magazine 2, and then, by a slight movement of the FD carrier 8, it is engaged with the hole in the FDI cartridge. It will be done.

After that, the FD feed hook 9 moves backward and the magazine 2
Take out FDI from. Then, due to the movement of the FD carrier 8, the FDl is held in the FD feeder 3 while the FD
It is transported to D4. Thereafter, the FD feed hook 9 advances to insert the FDI into the FDD 4. Thereafter, the FD feed hook 9 is removed from the hole in the FDI cartridge by a slight movement of the FD carrier 8. FD
The operation of returning the FDI from D4 to the magazine 2 is the reverse of the above operation.

[Effects of the Invention] As described above, according to the present invention, the FD feeder is structured so that the hole provided in the FD cartridge is hooked and the FD is taken in and out of the magazine or FDD, so that rollers, belts, etc. Compared to the mechanism that takes things in and out, there is no slippage, there is no generation of dust, and there are improvements such as the ability to simplify the circuit, and it is small.
It is possible to provide a highly reliable flexible disk autochanger that can search large amounts of data, and has great industrial value.
