Abstract

PURPOSE:To improve durability and to shorten an operating time by moving a table for moving a flexible disk on the front surface of a magazine and executing the taking-out and inserting of a flexible disk. CONSTITUTION:A flexible disk (FD)1 is housed in a rectangular box-shaped magazine 2 which is arranged parallelly with a flexible disk drive (FDD) 3. A table 4 for FD move, which is moved with being linked to a ball screw 8 to be rotated by a motor 7 for table move, is fitted to the front surface of this magazine 2. A holding device 6 to hold the FD1 on the table 4 for move is moved backward and forward in the direction of the magazine 2 by a motor 5 for move when the FD is inserted and taken out to the FDD 3. Then, the FD1 is taken out from the inside of the magazine 2 and housed into the FDD3. After that, writing or reading is executed. Thus, the durability is improved and the operating time can be shortened.

Description

[Detailed description of the invention] <Industrial application field> The present invention is office automation equipment (OA equipment).

The present invention relates to a large-capacity storage device using a magnetic disk that can store and search large amounts of various data in equipment such as audiovisual equipment (AV equipment) and electronic measuring equipment.

<Prior Art> Examples of conventional mass storage devices using magnetic disks as storage media are shown in FIGS. 3 and 4.

As shown in the drawing, a ring-shaped magazine 2 containing a plurality of magnetic disks (FD') is rotated and positioned by a drive transmission belt 10 powered by a stepping motor 9. The positioned FI) I is a flexible disk drive (FDD) that is moved back and forth at that position.
3) Data is being written and read.

<Problem to be solved by the invention> F of a conventional storage device that stores two ring-fold magazines.
The larger the number of DIs, the larger the size.

Also, when replacing the device main body 11 housed as shown in Figure 4,
In order to open the upper cover 12, the upper cover 12 must be removed from the upper part, which requires a large space at the upper part, which has the disadvantage of poor space efficiency.

In addition, a stepping motor 9 is used to rotate the magazine 2.
Because the drive transmission belt 10 is used, it is not possible to suddenly apply a large torque, and the 20 rotations of Tsuga 2 are slow (FD
I operation time is long.

Another drawback is that the holding torque of the stepping motor 9 is small, making it impossible to accurately position the device when standing or tilting it.

Furthermore, FDI is stored and taken out to magazine 2 and FDD3
Since the attachment and detachment is carried out using rubber rollers, there is a drawback that the rollers are subject to heavy wear and are not durable.

Means for Solving the Problems> The present invention eliminates the above drawbacks of the conventional technology and provides an FDI along the opening surface of a box-shaped magazine 2 in which a plurality of FDIs are stored side by side with an FDD 3 on which recording and reproduction are performed on the FDIs. and move F
This is a large capacity storage device using a magnetic disk that is provided with an FD movement table that holds DI.

<Function> The magazine 2 and the FDD 3, which are heavy and contain a plurality of FDIs, are not moved relative to each other as in the conventional case.
In the present invention, the heavy magazine 2 is fixed, and the FD moving table goes to the required FDI, takes it out, and then carries it to the FDD 3 to attach and detach it, so FI)I
The operating time will be shorter.

<Embodiment> An embodiment of a mass storage device using a magnetic disk of the present invention is shown in FIGS. 1 and 2.

The FDI shown in FIG. 1 is housed in a rectangular box-shaped magazine 2 that is lined up with an FDD 3 as shown in FIG. 2. At the front of this magazine 2, there is mounted an FD moving table 4 which is connected to and moved by a ball screw 8 rotated by a table moving motor 7.

It is attached. A holding device 6 that holds the FDI on a moving table 4 is moved back and forth in the direction of the magazine 2 by a moving motor 5 when the FDD 3 is inserted into and pulled out.

For the FDI currently stored in the magazine 2, the movement of the FD moving table 4 and the forward and backward movement of the holding device 6 are controlled, and the FDI is taken out from the magazine 2 and stored in the FDD 3 for writing or reading. .

Therefore, the magazine 2 can store a plurality of FDIs, and can be replaced with just one FDI or the entire magazine 2. In addition, since the heavy magazine 2 is moved (the FD moving table 4 moves and holds one FDJ, the weight of the moving object is small and can withstand sudden movements, and operation time is shortened. .

<Effects of the Invention> As described above, according to the present invention, the FD moving table 4 moves on the front surface of the magazine 2 to take out the FDI,
Since insertion is performed, the moving object is lightweight and can withstand sudden movement, and since rubber rollers are not used for taking out and inserting FDI into pDp, t, it is compact and durable using a magnetic disk. is obtained.

(FD), FIG. 2 is a plan view of the magazine and flexible disk drive (FDD) of the mass storage device according to the present invention.
) A perspective view of the external appearance of the moving table part; Figure 3 shows a magazine of an example of a conventional mass storage device using magnetic disks;
FIG. 4 is an external perspective view showing the relationship between FDDs, and FIG. 4 is an external perspective view of the main body of the apparatus shown in FIG. 3.
