When inserted, the locked state is released and the arm 26 is pushed toward the carriage 16 by the force of the leaf spring 47, and the magnetic head 1
5 and 25 sandwich the disk 1 at the positions of the openings 3 formed on the lower and upper surfaces of the hard case 2.

[Problem that the invention seeks to solve]

In the conventional flexible disk device mentioned above,
Since the carriage X6 and the terminal 26, which move within a distance of %1fD in the direction of insertion and removal of the disk 1, are arranged along the direction of insertion and removal of the disk 1, which is the direction of movement, it is possible to store the disk 1. There was a problem that a large space was required at the rear of the space, and the device was large and long from front to back.

SUMMARY OF THE INVENTION An object of the present invention is to provide a flexible disk device that requires little space at the rear or side of the disk storage space and can be constructed in a compact size.

[Failure to solve the problem]

The flexible disk device of the present invention has a pair of magnetic hoods that contact one side and the other side of the disk and are moved in the radial direction of the disk. a carriage disposed along the direction, having a magnetic head attached to one end to be in contact with one surface of the disk, and moving in the direction of insertion and removal of the disk; an arm that is arranged along orthogonal directions, has a magnetic head attached to one end to be in contact with the other surface of the disk, and moves together with the carriage in the insertion/removal direction of the disk; and a plate-like connecting member that connects to each other at the ends.

[Effect]

In the flexible disk device of the present invention, since the carriage and the arm are arranged along a direction perpendicular to the disk insertion/removal direction, which is the movement direction of each,
There is no need for space at the rear of the disc storage space, and since the carriage and arm are connected to each other by a plate-like connecting member at their other ends, almost no space is required on the sides of the disc storage space. , the device can be made smaller.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a plan view showing a main part of a flexible disk device according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof. The flexible disk device of this embodiment is arranged along the direction perpendicular to the insertion/removal direction of the disk 1 as shown by the arrow 4, and has a magnetic head 11 attached to one end to be in contact with one surface of the disk 1. A carriage 12 which should be 15 an arm 22 to which the head 21 is attached and which moves together with the carriage 12 in the direction of insertion and removal of the disk 1;
It is configured to include a plate-like connecting member 41 that connects the carriage 12 and the arm 22 to each other at their other ends.

The plate-like connecting member 41 is formed of, for example, a thin metal plate, and is attached to the other end surface of the carriage 12 with a screw 44, and has a bent portion 43 formed on its upper end side.

In the arm 22, a part 1 of an elastic connecting piece 46 made of a temporary spring or the like is fixed to the lower surface of the base end of the arm 22, and the other end of the elastic connecting piece 46 is held by a screw 45 through a holding temporary 42. and is fixed to the bending portion 43. As a result, arm 2
2 is always urged toward the disk 1 by the elasticity of the elastic connecting piece 46. The reason why the arm 22 is always biased toward the disk 1 in this way is that when the flexible disk device of this embodiment inserts the disk 1 into the device, the disk 1 moves downward together with the disk guide 5. This is because a throttle-in method is adopted in which the disk 1 is fixed to the bearing of the spindle motor 71, and at the same time, the arm 22 is also lowered so that the magnetic head 21 comes into contact with the disk 1.

Guides 51 and 52 passing through the carriage 12 are attached to the chassis 31, and a stepping motor 61 is attached to the lower side of the chassis 31, and although not shown, converts the rotational motion of the stepping motor 61 into linear motion. A mechanism is provided, a plate-like connecting member 41 is attached to the end of this mechanism, and a stepping motor 61
Due to this rotation, the carriage 12 moves together with the arm 22 along the guides 51 and 52 within a distance in the direction of insertion and removal of the disk 1.

Similar to the conventional flexible disk device shown in FIGS. 3 and 4, the disk 1 is rotatably housed in a hard case 2. The spindle motor 71 with a thin structure is inserted into the device through an opening formed in the
It is attached to the spindle shaft 72 of , and is rotated by the rotation of the spindle shaft 72 . Before inserting the disk 1, the arm 22 is connected to the elastic connecting piece 46 by an arm opening mechanism (not shown).
When the disc 1 is inserted between the carriage 12 and the arm 220, the lock state is released and the elastic connecting piece 46 opens. 3 and 4, the arm 22 is pushed toward the carriage 12 by the force, and the magnetic heads 11 and 21 sandwich the disk 1 at the openings 3 formed on the lower and upper surfaces of the hard case 2. This is similar to the case of the conventional flexible pull disk device shown in FIG.

In the flexible disk device of this embodiment, the carriage 12 and the arm 22 are disposed along the direction perpendicular to the direction of movement of the disk 1, which is the direction in which the disk 1 is inserted and removed. In addition, the carriage 12 and the arm 22 are connected to the plate-like connecting member 4 at their other ends.
Since the discs 1 and 1 are connected to each other, almost no space is required on the sides of the storage space for the discs 1, and the apparatus is made extremely compact.

〔Effect of the invention〕

As explained above, according to the present invention, the carriage and the arm are disposed along the direction perpendicular to the disk insertion/removal direction, which is the movement direction of each, and the carriage and the arm are disposed at the other ends of the respective carriages and the arms. Since they are connected to each other by the plate-like connecting member, almost no space is required at the rear or side of the disk storage space, and the device can be made compact.

Further, there is an effect that the connecting portion between the carriage and the arm can be made simple.
