Abstract

PURPOSE:To make the floppy disk drive thin and to save space by designing a side arm so that a part of the side arm collapses when the arm is raised to touch the upper cover when a floppy disk is inserted to the device. CONSTITUTION:A head 3 for the side 0 of a disk is provided on the one surface of a carriage main body 1, while a head 5 for the side 1 of the disk is provided on an arm 4 for the side 1 facing to the head 3 for the side 0 through the floppy disk 2. The arm 4 for the side 1 and the arm 10 for the side 1 forms a link mechanism with a shaft 11, and a spring 12 is engaged on each side of the arm 4 and 10 with spring engagements 13-15 so that the arm 4 for the side 1 is given force to the direction B and rotated in the C direction by the spring 12. However, the arm 4 is stopped by a stopper 16 and rotates no more when it comes to parallel to the arm 4. Therefore, when a floppy disk cartridge 2 is to be inserted, it is not necessary to raise the side arm 4 high. Thus, the device can be made thin and the space is saved.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a floppy disk device.

(Prior Art) In a 3.5-inch floppy disk device for recording and reproducing data, a carriage assembly 1 for holding and moving a magnetic head has conventionally been constructed as shown in side views in FIGS. 6 and 7. I was configuring it. FIG. 6 shows a state in which the floppy disk cartridge 2 is completely inserted into the apparatus, and FIG. 7 shows a state in which the floppy disk cartridge 2 is about to be inserted. A side O side head 3 is attached to one side of the carriage assembly 1, and a side 1 side head 5 is attached to the side 1 arm 4 side at a position facing this side 0 side head 3 with the floppy disk interposed therebetween. It is being

This side 1 arm 4 is attached to one end of the carriage assembly 1 via a leaf spring 6.

Further, a spring 7 for pushing the side arm 4 in the direction of arrow A is attached to the carriage assembly 1. When the floppy disk cartridge 2 is inserted into the apparatus, that is, when it is inserted into a receiver in a spindle motor (not shown), the receiver latch is released, and the lifting part 8 attached to the receiver is lowered together with the receiver, and the floppy disk cartridge is removed. 2 is also lowered, placed on a spindle motor (not shown), and placed in a loaded state. At the same time, the side 1 arm 4 on which the hook part 9 was supported by the lifting part 8 is lowered. Therefore, the side 0 head 3 and the side 1 head 5 come into contact with a magnetic sheet (not shown in this figure) inside the floppy disk cartridge 2, respectively.

When ejecting the floppy disk cartridge 2,
Since the receiver is lifted by operating an eject button (not shown), the hook part 9 is lifted by the lifting part 8 attached to the receiver, the side 1 arm 4 is lifted, and the side 1 side head 5 is separated from the magnetic sheet. At the same time, the floppy disk cartridge 2 lifted by the receiver is ejected from the apparatus by an ejection mechanism (not shown).

As described above, in the conventional floppy disk device, when the floppy disk cartridge 2 is loaded into the device, in order to prevent the floppy disk cartridge 2 from coming into contact with the head 5 on the side 1 side, the side 1 arm 4
had to be lifted high. Therefore, it was necessary to increase the height of the device so that the side 1 arm 4 could be lifted higher. In other words, the thickness of the entire device has become thicker.

(Problems to be Solved by the Invention) As detailed above, in conventional floppy disk drives, when inserting a floppy disk, it is necessary to lift the side arm high, which increases the thickness of the floppy disk drive. There was a problem where the

SUMMARY OF THE INVENTION It is an object of the present invention to provide a floppy disk device that solves the above problems, reduces the thickness of the floppy disk device, and realizes space saving.

[Structure of the Invention] (Means for Solving the Problems) In the floppy disk device of the present invention, the side arm installed on the top surface serves as a link mechanism, and when the floppy disk is not inserted into the device, The side arm is lifted upward and bent in contact with the upper cover.

(Function) According to the floppy disk device having the above configuration, even if the side arm is raised when inserting a floppy disk into the device, the side arm hits the upper cover and a part of it is bent. No need to lift the arm high. Therefore, the thickness of the floppy disk device can be reduced, and the space of the device can be saved.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings of FIGS. 1 to 5.

1 to 3 are side views of the floppy disk device used in this embodiment. FIG. 1 shows the state in which the floppy disk cartridge 2 has been inserted into the device, and FIG. 2 is completely inserted into the device (loaded state), and FIG. 2 shows the intermediate state. In addition, Figures 4 and 5 refer to Figures 1 to 3.
It is an enlarged view of the X portion surrounded by the circle in the figure, FIG. 4 is a plan view, and FIG. 5 is a side view. First, the structure of the floppy disk device of this embodiment will be explained. A side 0 side head 3 is installed on one side of the carriage assembly 1. Further, on the side 1 arm 4, at a position facing the side 0 side head 3 with the floppy disk 2 interposed therebetween,
A head 5 on side 1 is installed. Side 1 arm 4 constitutes a link mechanism with side 1 arm 10 via shaft 11. Also, side 1 arm 4.10
On both sides of the spring 12 are spring hooks 13 and 14, respectively. It is attached by a spring hook 15, which applies a force to the side 1 arm 4 in the direction of arrow B.

The side 1 arm 4 is rotated in the direction of arrow C by the spring 12, but is stopped by a stopper 16 when it becomes parallel to the side 1 arm 4, and does not rotate any further.

Next, the operation when inserting the floppy disk cartridge 2 into the floppy disk device will be explained. When the floppy disk 2 is inserted (FIG. 1), the lifting portion 8 attached to the receiver is lifted upward by a receiver latch (not shown). Therefore, the hook portion 9 is lifted upward, and the side 1 arm 4 comes into contact with the upper cover 7. Therefore, the side 1 arm 4 rotates about the shaft 11 in the opposite direction to the arrow C against the force of the spring 12. At this time, enough space is secured so that the floppy disk cartridge 2 and the side 1 head 5 do not come into contact with each other. The state in which the floppy disk 2 is inserted, the receiver latch (not shown in this figure) is released, and the lifting part 8 has moved slightly downward (
In FIG. 2), the hook part 8 moves downward following the lifting part 7, and the side 1 arm 4 and the side 1 arm 10 become parallel. When the floppy disk 2 is completely installed (FIG. 3), the lifting part 7 is lowered and the hook is separated from the part 8, as in the conventional example. Then, the head 3 on the side 0 comes into contact with a magnetic sheet (not shown in this figure) of the floppy disk 2, and a constant load is applied to the head 3 on the side 1 by the spring 7.

As described in detail above, according to the floppy disk device of this embodiment, the side 1 arm is a link mechanism via the shaft, and is configured to bend when it comes into contact with the upper cover. Therefore, even when inserting a floppy disk into the floppy disk device, there is no need to raise the side arm high, making it possible to reduce the thickness of the device and save space.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a floppy disk device that is thin and space-saving.
