Abstract

PURPOSE:To record many pieces of information without replacing plural floppy disks by driving plural magnetic recording media loaded in a floppy disk drive by a single driving motor. CONSTITUTION:For example, two magnetic recording media such as the floppy disks (FD) 11 can be loaded in the floppy disk drive (FDD). Two FDs 11 loaded in the FDD are rotated by one driving motor 15 through a belt 16 and a pulley 17. Read/write is performed to the respective FDs 11 by a head 14 driven by a head driving motor 18. Since the plural FDs are driven by the single motor 15, recording is performed without replacing the plural FDs.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a method for storing a plurality of magnetic recording media housed in a hard case with a shutter in an electronic device such as a personal computer or a personal workstation. This invention relates to a floppy disk storage device.

(Prior Art and Problems to be Solved) Conventionally, in electronic devices such as personal computers and personal workstations, magnetic disks such as floppy disks housed in a hard case made of plastic or other material with a shutter have been used as a means of recording information. A recording medium (hereinafter referred to as FD) is used. On the other hand, personal computers
They have been realized in sizes ranging from laptop size to book size, and are becoming increasingly lighter and thinner and smaller. Along with this, F.
A floppy disk storage device (hereinafter referred to as FD) that controls
D) was also desired to be light, thin, compact, and have a larger storage capacity, but current technology has its limits, and for operational purposes, multiple FDs had to be replaced in one FDD.

However, this method has the disadvantage that it burdens the user's work and reduces operability.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks, and aims to provide a floppy disk storage device that can record a large amount of information without replacing multiple floppy disks.

[Structure of the Invention] (Means for Solving the Problems) The floppy disk storage device of the present invention is characterized in that a plurality of magnetic recording media are driven by a single drive motor.

(Operation) A plurality of magnetic recording media mounted on a floppy disk storage device are driven by a single drive motor.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a floppy disk storage device according to an embodiment of the present invention, and FIG. 2 is a side view showing the main structure of the floppy disk storage device in FIG. 1. The floppy disk storage device (hereinafter referred to as FDD) can be equipped with two magnetic recording media II (hereinafter referred to as FDll) such as floppy disks, for example. The FDD includes a magnetic recording media mounting port 12 (hereinafter referred to as the FD mounting port 12) for mounting the FDII, a mounting mechanism 13 for mounting the FDII, a head 14 for reading and writing information to the FDII, and a drive for rotating the FDII. A motor 15, a means 16 for transmitting the driving force of the drive motor 15, a drive pulley 17 that guides and rotates the FDII, and a head drive motor 1 that moves the head 14.
It consists of 8. In the embodiment of the present invention, for example, a belt (hereinafter referred to as belt 16) is used as the means 16 for transmitting the driving force of the drive motor 15. FDD
The two FDIIs attached to the FD II are configured to be rotated by a drive motor 15 via a belt 16. FDI
I is housed in a hard case 19 made of plastic or the like, and information is recorded on a data recording surface 21 that appears from a window 19a when a shutter 20 is opened or closed. The head 14 of the FDD comes into contact with the data recording surface 21 to read and write information. A hub 22 that engages with the drive pulley 17 is provided on the bottom of the FDII. The hub 22 has a chucking hole 22a and a positioning hole 22b formed therein.

FIG. 3 is a perspective view showing the configuration of the floppy disk mounting mechanism in FIG. 1. The mounting mechanism 13 includes a receiver 23, an eject plate 24, and a guide plate 25. The receiver 23 is provided with a receiver pin 23a, a rotatable shutter opener 26, and a rotatable stopper 27. The eject plate 24 includes an eject pin 24a and a groove 2.
4b, an eject button 24c, and a fixing pin 24d. The guide plate 25 has a vertical hole 25.
a and a horizontally elongated hole 25b. The receiver pin 23a is engaged with the groove 24b and the vertically elongated hole 25a. The eject pin 24a is engaged with the horizontally elongated hole 25b. As a result, the receiver 23 moves up and down with respect to the guide plate 25, and the eject plate 24 moves back and forth. The eject button 24c of the eject plate 24 is operated when ejecting the FDII from the FDD. The eject plate 24 is biased in the direction of arrow A by a spring 28 hooked to the guide plate 25. The shutter opener 26 has an open pin 26a, and is biased in a certain direction by a spring 29. The stopper 27 has a stopper pin 27a,
It is biased in a certain direction by a spring 3G.

The stopper 27 is formed with an engaging portion 27b that engages with the fixing pin 24d of the eject plate 24.

Next, installing a floppy disk will be explained. First, the FDII is inserted into the FDD from the FD mounting port 12.

The shutter 20 of the FDII engages with the open pin 26a of the shutter opener 26. As the FDll is inserted, the shutter opener 26 rotates and the shutter 20 is gradually opened. When the FDII is further inserted, it engages with the stopper pin 27a and the stopper 27 rotates.

When the insertion of FDII is completed, the retaining portion 27 of the stopper 27
b comes off from the fixed bottle 24d. As a result, the eject plate 24 is moved from the guide plate 2 by the spring 28.
5 and moves in the direction of arrow A. As the eject plate 24 moves, the receiver 23 whose receiver pin 23a engages with the groove 24b is guided by the vertical hole 25a of the guide plate 25 and moves in the direction of arrow B. The FDII is attached to the drive pulley 17 by the above operations. The FDII mounted on the drive pulley 17 is positioned by engaging the center pin 17a and the drive pin 17b in the chucking hole 22a and the positioning hole 22b, respectively.

Next, the case of ejecting the floppy disk will be explained. First, press the eject button 24c. As a result, as the eject plate 24 moves, the receiver 23 moves the receiver pin 23a to the groove 24b and the guide plate 2.
5 in the vertical hole 25a, and move in the direction of arrow C. When the eject button 24c is further pressed, the fixing pin 24
d is fixed to the engaging portion 27b of the stopper 27. At this time, the stopper pin 27a of the stopper 27 is in a state where it urges the FDll in the direction of arrow A. This causes the shutter opener 26 to rotate and return to its original position. The restoring force of the shutter opener 26 discharges the FDll. Each FDII is mounted in the FD mounting port 12 shown in FIG. 1 by the mounting mechanism 13.

As described above, according to the configuration of the present invention, a plurality of FDs attached to an FDD can be rotated by a single drive motor. Therefore, since there is no need to provide a drive motor for each FD, the FDD can be made thinner.

In the embodiment of the present invention, a single drive motor can drive two
Although the configuration has been described in which two FDs are rotated, if the drive shaft of the drive motor is extended and a belt and a drive pulley are provided, it is possible to further increase the number of FDs. Furthermore, in the embodiments of the present invention, a configuration in which a plurality of FDs are rotated synchronously by a single drive motor has been described, but a configuration in which the connection between the drive motor and the belt is switched using a solenoid or the like may be used. It is also possible to rotate only the desired FD.

[Effects of the Invention] As described above, according to the present invention, a plurality of FDs attached to an FDD can be rotated by a single drive motor, so the FDD can be made thinner.
