Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data recording device such as a computer and a word processor, and more particularly to a cartridge mounting device of a drive device that drives a cartridge containing a recording medium such as a magnetic disk or an optical disk.

2. Description of the Related Art In recent years, the demand for a floppy disk device as an external recording device for a computer is rapidly increasing. This is because the floppy disk device is easy to handle and inexpensive, and can be attached and detached like a tape memory. Recently, portable computers have been built in and word processors have been built in. Recently, as these devices themselves have become smaller and lighter, smaller and thinner floppy disk devices have been required.

A conventional cartridge mounting device in the floppy disk device will be described below with reference to the drawings.

FIG. 4 is a perspective view of a holder portion of a conventional cartridge mounting device, and FIG. 5 is an operation explanatory view. Reference numeral 6 denotes a holder, and 14 denotes an opening / closing member slidably attached to the holder, which includes an opening / closing claw 14a of the shutter and a rack tooth portion 14b. Reference numeral 15 denotes a slide plate slidably attached to the holder, which includes rack teeth 15a and pins 16. The pin 16 is inside the holder 6, and when the cartridge is inserted, the pin 16 engages with the cartridge and moves in the insertion direction. Since the opening / closing member 14 and the slide plate 15 mesh with the attached pinion 17, they slide in opposite directions. Further, since the slide plate 15 is biased by the tension spring 18 in the direction opposite to the insertion direction of the cartridge, as a result, the opening / closing member.
14 is biased in the same direction as the cartridge insertion direction. The pins 6a are two pairs of pins provided on both sides of the holder 6, and a total of four pins 6a engage with a cartridge-mounted base (not shown) to move the holder 6 up and down. The pin 6a also serves as a guide for the opening / closing plate 14.

Next, the operation of the conventional example will be described. In FIG. 5a, the cartridge 4 is not inserted, and the slide plate 15 is urged to the left and the opening / closing member 14 is urged to the right in FIG. 5 by the action of the tension spring 18 and the pinion 17. . FIG. 5b shows a state in which the cartridge 4 is inserted partway into the holder 6, the pin 16 is engaged with the cartridge 4, the slide plate 15 is moved to the right, and the opening / closing member 14 is interlocked with the pinion 17. Move to the left. At this time, the opening / closing claw 14a of the shutter provided on the opening / closing member 14 abuts on the protrusion 5 of the cartridge, and the cartridge 4 is further inserted, whereby the opening / closing claw 14a of the shutter provided on the opening / closing member 14 is protruded. 5 is moved to the left while pushing, and the shutter 2 of the cartridge is opened in cooperation with the protrusion 5.
In FIG. 5c, the cartridge is pushed to reach the right end portion of the holder 6, and accordingly the opening / closing member 14 projects from the holder 6, and the opening / closing claw 14a of the shutter provided on the opening / closing member 14 has a protruding portion. Since 5 is pushed to the left, the shutter is fully opened, and the magnetic disk can be seen through the head window 3 without being covered.

The operation of keeping the separation distance of the cartridge 4 constant will be described with reference to FIG. In FIG. 6, the holder 6 having the pin 6a described above is incorporated as a cartridge mounting device. The holder 6 is inside the drive plate 18 having the cam portion 18a, and the pin 6a attached to the holder 6 moves by using the cam portion 18a of the drive plate 18 as a guide.
When the drive plate 18 is horizontally moved to the left side in the drawing from the state of FIG.
Move up in the drawing along b. When the drive plate is further pushed, the pin 6a moves to the horizontal portion 18c of the cam portion as shown in FIG. 6b, and even if the drive plate 18 is further moved, the holder moves upward (in the drawing). It does not move, which keeps the separation distance constant.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional cartridge mounting device, the rack teeth are cut on the opening / closing member that opens and closes the shutter of the cartridge, and the same rack teeth are cut on the slide plate. Since both racks are connected by a pinion and used as a reversing device for moving the opening / closing member of the shutter, it is necessary to first align the phase of each tooth when installing. In addition, since the rack teeth and the pinion are constantly in contact with each other when the cartridge is inserted, the contact resistance is increased and it is difficult to smoothly insert the cartridge.

A second problem is that the engaging member incorporated in the holder exerts a force in the ejecting direction of the cartridge after the cartridge is inserted. In order to maintain a constant distance between the cartridge and the base body, the cam portion of the drive plate is used to move the holder up and down. According to this, the cartridge is pushed out by the engaging member before the holder completely rides on the horizontal portion of the cam portion. The present invention aims to provide a cartridge mounting device which can solve this problem.

Means for Solving the Problems A cartridge mounting device of the present invention is a wire having sufficient flexibility to connect an inversion device, an engaging member that engages with a cartridge and operates integrally, and an opening / closing member. Shaped member,
A pulley is provided between the engaging member and the opening / closing member.

By virtue of this, the flexible linear member and the pulley are the first, so there is no need for positioning during assembly, and the reversing mechanism by rotation of the pulley allows smooth insertion and ejection of the cartridge. You can do it.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 1 shows a perspective view of a holder portion of a floppy disk device according to an embodiment of the present invention. Reference numeral 6 is a holder, and 7 is an opening / closing member slidably attached to the holder. The opening / closing member 7a is provided with a hook portion 7b that connects the linear member 11 and the tension spring 12. Reference numeral 10 denotes an engagement member slidably attached to the holder, which includes an engagement claw 10a that enters the inside of the holder and contacts the cartridge, and a hook portion 10b that connects the linear member 11. The opening / closing member 7 and the engaging member 10 are connected by a linear member 11 via a pulley 8 attached to a substantially central portion of the holder 6.
