JPS6187261A - Floppy disk device - Google Patents

Abstract

PURPOSE:To charge a floppy disk without secondary action by locking a trigger member and ejecting a floppy disk when pushing in a manual operation member and releasing the member when charging the floppy disk. CONSTITUTION:When a floppy disk is inserted from the front bezel side and the hanging piece 14d of an ejector 14 is pressed by the front edge of a disk jacket 20, the ejector 14 turns counterclockwise in the figure. When it turns to a position where a contact edge becomes nearly parallel to the front edge of the jacket 20, a trigger 7 turned together releases a locking pin 4 to make a slide lever 4 free, and moves the lever 4 to the right in the figure. The slide lever 4 released locking by the trigger 7 moves slowly to the right in the figure at nearly uniform speed. In the meantime, a collet 8b is lowered slowly, and the floppy disk is chucked exactly to a starting member directly connected to a driving motor.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a floppy disk device, and more particularly to a floppy disk device having a loading mechanism.

(Prior art) A front-loading floppy disk device is
As seen in Japanese Unexamined Patent Publication No. 59-90204, etc., after a floppy disk is inserted into the device, the disk is usually clamped by closing the door, rotating a lever, or pushing in a button. is configured to do so.

For this reason, in conventional devices, several operations are required to load the disc, and since the disc is clamped by an external force, the force applied to the disc and the clamping speed are not constant, which causes the disc to load. Inconveniences such as poor alignment and incomplete clamping are likely to occur.Furthermore, since the front bezel and buttons protrude from the front bezel, they may get in the way when transporting the device or may damage the device. There was no JR train.

(Purpose) The present invention was made in view of the above problem, and its purpose is to
It is an object of the present invention to provide a floppy disk that can be transported without any subsequent operations and has good transportability.

Another object of the present invention is to provide a new floppy disk device capable of accurate and stable disk clamping.

(Structure) That is, the present invention is characterized by a manual operation member that is attached to the main body of the device so as to be removable and to which a biasing force in the protrusion direction is applied, and a manual operation member that acts on the manual operation member to move the member in the protrusion direction. a control member that controls the speed; a clamp member that contacts a portion of the manual operation member when moving in the ejection direction and is displaced to couple the floppy disk to the drive member; A floppy disk drive device comprising a trigger member that locks the member to a pushing device and is displaced in a direction to eject the floppy disk at a loading position, and is also displaced in a direction to release the manual operation member in conjunction with the loading operation of the floppy disk. Located in the disk device.

Therefore, details of the present invention will be explained below based on illustrated embodiments.

FIG. 1 shows an example of the device according to the present invention with the cover removed. In the figure, reference numeral 1 is a floppy disk device body with a front bezel 2 on the right side, and this body 1 is located in the middle. The stretched sub-frame 3 defines an upper section as a floppy disk loading chamber and a lower section as a chamber for arranging electrical components.

4 is a slide lever provided with a bushing button 6 at one end, and is reciprocably attached to one side of the main body 1 by fitting pins 5.5 on the subframe 3 into long holes 4a, 4a. , a pin 4b is planted at the inner end of the lever 4 to be locked by the trigger 7 when the lever 4 is pushed in, and
A roller 4C is provided on the outer side of the lever 4. When the lever 4 moves in the protruding direction, a roller 4C comes into contact with a cam 8a of a collet lever 8, which will be described later, and pushes it up.

The slide lever 4 also has a stop piece 4d bent at right angles to the longitudinal direction on the inside thereof, and the lever 4 is supported by a coil spring acting on the stop piece 4d via a tension plate 9. The lever 4 is always subjected to an urging force in the protrusion direction by the lever 4, and the lever 4 is further provided with a damper 11 as shown in FIG. 4 on its upper surface. That is, this damper 11 is composed of several laminated plate members 11a...tib..., one end of which is alternately fixed to a pin 5 on the subframe 3 and a pin 4e on the slide lever 4. At the same time, by attaching the other end slidably, the relative movement between the plates 11a and llb that occurs when the slide lever 4 moves is suppressed by the viscosity of the lubricating oil interposed between the plates 11a and llb. It is configured to prevent the slide/head 4 from rapidly moving in the protruding direction.

On the other hand, the trigger 7, which is located inside the main body 1 and locks the above-mentioned pin 4b of the slide lever 4, has a central angle with an engaging recess 7a for engaging the pin 4b at the - level and a falling piece 7b at the lower level. has a fan shape of approximately 90@, and the trigger spring 13
Ejector 1, which will be described later, is given dextrorotation by
4 and is pivotally supported on a shaft 12 on the subframe 3. The ejector 14 is a fan-shaped member with a center angle of approximately 90° for ejecting the floppy disk using the urging force of the trigger spring 13 and the ejector spring 15, and one side of the ejector 14 contacts the pin 4b on the slide lever 4. A recess 14b (Fig. 2) is formed in which the pin 14b is received in a non-contact state, and the other side forms an abutting edge 14a that abuts the falling piece 7b of the trigger 7. A falling piece 14d that comes into contact with the disk jacket 20 is bent and formed on the outside thereof.

On the other hand, a shaft 17 is held horizontally along the slide lever 4 on a bracket 16 provided on the sub-frame 3, and a cam 8a that contacts the roller 4C on the slide lever 4 is mounted on the blade. A collet lever 8 equipped with a collet 8b that fits into the center hole of the disk 7 and brings it into pressure contact with a contact member on a drive motor shaft (not shown).
However, the cam 8a is swingably mounted so that the cam 8a side is always kept in a depressed position by a spring 18.

Next, the operation of the device configured in this way will be explained.

Figure 1 shows the state with no floppy disk loaded.
In other words, this shows the state after pushing in the bushing button 6 and ejecting the floppy disk.

In this state, the trigger 7 is biased by the spring 13 and rotates clockwise in the figure, and its retaining portion 7a locks the pin 4b at the inner end of the slide lever to hold the slide lever 4 in the pushed-in position. ing. Further, in this state, the ejector 14 is also biased by the ejector spring 15 and maintains a right-rotated posture, and the collet lever 8 is tilted by the spring 18 with the cam 8a side facing down, and the collet 8b and the contact point (not shown) The position allows a floppy disk to be inserted between the members.

In this state, insert a new floppy disk from the front bezel 2 side and press the falling piece 14cl of the ejector 14 with the front edge of the disk jacket 20, the ejector 14 will press the trigger 7 with one contact edge. While pressing the falling piece 7b, it rotates counterclockwise in the figure against the trigger spring 13 and the ejector spring 15. When the ejector 14 rotates until one of the abutting edges becomes almost parallel to the front edge of the jacket 20, the trigger 7 that rotates together releases the locked pin 4b and frees the slide lever 4. , the lever 4 is moved to the right in the figure by the tension of the spring 10 acting on the rising piece 4d of the lever 4 via the tension plate 9 (No. 2.3).
figure).

By the way, as described above, this tension plate 9 rotates clockwise in the figure under the tension of the spring 10.
Hold the roller 9a provided at one end of the slide lever 4.
Since it is configured to press the rising piece 14d that is perpendicular to the direction of movement of the pin 5, its acting force is weak at the beginning of the rotation when the vertical distance between the pin 5 and the roller 9a is long, and becomes strong at the end. . On the other hand, the tension of the spring 10 tends to be strong at the beginning of the rotation when the spring 10 is at its most extended state, and becomes weaker at the end, so the slide lever 4 receives approximately equal force throughout its entire movement. Furthermore, this movement of the slide lever 4 is sufficiently damped by the viscosity of the sliding sleeve interposed between the damper plates 11a and 11b, which alternately move relative to each other in opposite directions on the lever 4 (the fourth figure).

Therefore, the slide lever 4 released from the lock by the trigger 7 moves gently to the right in the figure at approximately the same speed, and during this time the roller 4C in contact with the cam piece 8a pushes it up (the fifth Figure) Reverse the collet lever 8,
A collet 8b provided with low quality is gently lowered to accurately chuck the floppy disk just inserted into a landing member directly connected to a drive motor.

Ejector 14 not in direct contact with bottle 4b on par 4
However, since the ejector spring 15 rotates clockwise due to the tension of the ejector spring 15 acting on itself, the floppy disk inserted halfway is pushed out by the torque.

In addition, the damper indicated by the reference numeral 11 in the above-described embodiment can be replaced with another speed regulating mechanism consisting of an escape and pallet lever, and the swinging mechanism of the collector lever 8 can be replaced with a slide lever/release mechanism. -4 may be provided with a cam, and the collector lever 8 may be provided with a cam follower that comes into contact with the cam.

(Effects) As described above, according to the present invention, by providing the trigger member, the trigger member is locked when the manual operation member is pushed in and the floppy disk is ejected, and this member is released when the floppy disk is loaded. With this structure, this manual operation member, which protrudes only when a floppy disk is loaded, makes it possible to visually confirm the loading state, and at the same time, by holding it in the pushed-in position when the floppy disk is not loaded, various obstacles can be prevented when moving the device. can be prevented.

Moreover, the control member suppresses the moving speed of the manual operation member in the protrusion direction, and the clamp member is displaced during this movement to perform chunking of the floppy disk, so that a single operation of inserting the floppy disk can be performed. Not only can a disk clamping operation be performed, but the floppy disk can always be accurately and reliably clamped at a controlled speed.
