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 unique loading mechanism.

[Prior art] Front loading type floppy disk devices, as seen in Japanese Patent Application Laid-Open No. 59-90204, etc., usually require the user to close the door or turn a lever after the floppy disk is installed in the device. The disc is configured to be clamped by pressing the push button or by pushing the push button.

For this reason, conventional devices require several movements to load the disk, and because the disk is clamped using an external force, the force applied to the disk and the clamping speed are not constant, which causes problems. Therefore, problems such as disk alignment failure and incomplete clamping are likely to occur.Furthermore, since the levers and push buttons protrude from the front bezel, they may get in the way or damage the device when transporting the device. There was a possibility that there was no such thing.

[Purpose] The present invention has been made in view of the above problems, and its purpose is to make it possible to load a floppy disk without causing various problems such as damage to the device during transportation. It is an object of the present invention to provide a floppy disk that can be transported without secondary operations and has good transportability.

[Structure] In other words, 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 is applied with a biasing force in the protrusion direction, and a part of the manual operation member when moving in the protrusion direction. A member that contacts and is displaced to connect the floppy disk to the drive member, and a member that locks the manual operating member in the pushed-in position in conjunction with the pushing operation of the manual operating member and ejects the floppy disk that is in the loading position. The present invention provides a floppy disk device including a trigger member that displaces the manual operation member in the direction of opening the manual operation member in conjunction with the mounting operation of the floppy disk.

[Example] Therefore, the details of the present invention will be explained below based on the illustrated example.

FIG. 1 shows an example of the device according to the present invention with the cover removed. In the figure, reference numeral 1 is the main body of the floppy disk device with the front bezel 2 on the right side. A subframe 3 stretched over the subframe 3 defines a lower part as a loading chamber for a floppy disk and an upper part as a chamber for arranging electrical components.

Reference numeral 4 denotes a slide lever which is a manually operated member with a push button 6 at one end, and can be reciprocated to one side of the main body 1 by fitting the elongated holes 4a, 4a into pins 5, 5 on the subframe 3. installed on. A pin 4b is implanted at the inner end of the slide lever 4 to be locked by a trigger 7, which is a trigger member, when the slide lever is pushed in, and a pin 4b, which will be described later when the lever 4 moves in the protruding direction, is implanted at the outer side. A roller 4c that comes into contact with the cam 8a of the collect lever 8 and pushes it up is provided on a shaft.

The slide lever 4 also has a stop piece 4d bent at right angles to the longitudinal direction on the inside thereof. The slide bar 4 is always subjected to a biasing force in the projecting direction by a coil spring 10 acting on the stop piece 4d via the tension plate 9.
A damper 11, which is a control member, as shown in FIG. 4 is provided on its upper surface. That is,
This damper 11 is made up of several laminated plate members 1.
1a...11b..., and one end of these is alternately fixed to the pin 5 on the subframe 3 and the pin 4e on the slide lever 4, and the other end is slidably attached to the slide lever. Each of these plates 11a, 11 that occurs during the movement of 4
The structure is such that the viscosity of the lubricating oil interposed between the plates 11a and 11b prevents the slide lever 4 from rapidly moving in the projecting direction.

On the other hand, the slide lever 4 located inside the main body 1
The trigger 7 for locking the above-mentioned pin 4b has a fan shape with a center angle of approximately 90°, with a recess 7a for engaging the pin 4b on one edge and a falling piece 7b on the other edge. It is pivotally supported on a shaft 12 on the subframe 3 together with an ejector 14, which will be described later, while being given dextrorotation by a trigger spring 13. Ejector 14 includes trigger spring 13 and ejector spring 1
It is a fan-shaped member with a central angle of approximately 90° to eject the floppy disk with a biasing force of 5, and one side of it is connected to the pin 4 on the slide lever 4.
It forms a contact edge 14a that contacts the pin 4b, and there is a recess 14b that receives the pin 4b in a non-contact state.
(Fig. 2), the other side forms a contact edge 14c that contacts the falling piece 7b of the trigger 7, and a falling piece 14d that contacts the disk jacket 20 is folded outward from the contact edge 14c. It is bent and formed.

On the other hand, the bracket 16 provided on the subframe 3
A shaft 17 is held horizontally along the slide lever 4, and one wing has a cam 8a that comes into contact with the roller 4c on the slide lever 4, and the other wing has a cam 8a that fits into the center hole of the floppy disk 20. A collet lever 8, which is a clamping member equipped with a collet 8b for press-contacting the collet 8b to a contact member on a drive motor shaft (not shown), is always held in place by a spring 18.
It is attached so that it can swing so that the side maintains a depressed position.

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

Before that, an outline of the operation of the apparatus will be explained based on FIGS. 6 to 9.

As shown in FIG. 6, the pin 4b implanted in the slide lever 4, which is a manual operation member, engages with the engagement recess 7a of the trigger 7, and the coil spring 10 is attached to the slide lever 4 in the projecting direction. Forces have been added, but they are not moving. In this state, the floppy disk 20 is inserted into the main body of the apparatus in the direction of arrow 101. Then, the falling piece 7b of the trigger 7 will touch the floppy disk 20.
, the trigger 7 rotates in the direction of arrow 102 shown in FIG. 7 against the biasing force of the trigger spring 13, and as shown in FIG. The slide lever 4 is disengaged from the slide lever 7a, and the slide lever 4 moves in the outward projecting direction shown by the arrow 103 due to the biasing force of the coil spring 10. The slide lever 4 is provided with a roller 4c, and as the slide lever 4 moves in the direction of arrow 103, as shown in FIG.
The roller 4c pushes up a cam 8a provided at one end of the collect lever 8, which is a clamp member provided on the shaft 17 so as to be able to swing vertically, and the collect lever 8 moves around the shaft 17 in the direction indicated by the arrow 10 in the figure.
4, 105, and the collet 8b provided at the other end of the collet lever 8 clamps the floppy disk 20. At this time, when the slide lever 4 is moved at high speed in the protruding direction of arrow 103 by the force of the coil spring 10, the floppy disk 20 is also clamped at high speed by the collector lever 8, so that the collet 8b is centered on the floppy disk 20. A phenomenon occurs in which the floppy disk enters the center hole of the floppy disk before the floppy disk 20 is completely blown, and the center hole of the floppy disk 20 is destroyed. For this reason, the slide lever 4 is provided with a damper 11, which is a control member, to suppress its moving speed and obtain an appropriate speed.

Next, when the push button 6 is pressed to take out the floppy disk 20 while the floppy disk 20 is loaded, the push button 6
The roller 4c on the slide lever 4 released from the cam 8a, and the collector lever 8 is reversed by the biasing force of the spring 18, raising the collet 8b at the other end and causing the floppy disk 20 to chuck. solve. On the other hand, the pin 4b of the slide lever 4 slides in contact with the abutting edge of the trigger 7 and moves toward the center thereof, and engages the engagement recess 7a of the trigger 7.
When it reaches the point, the trigger spring 13 rotates it to the right,
With this torque, the front edge of the floppy disk 20 that is in contact with the rising piece 7b of the trigger 7 can be pressed and the floppy disk 20 can be pushed out toward the front bezel 2 side, and at the same time, the slide lever 4 is moved so that its pin 4b It engages with the engagement recess 7a of the trigger 7, is locked in the pushed-in position, and returns to its original state.

The above is an overview of the operation of this device, but the points shown in FIGS. 1 to 3 are similar in that it is possible to load a floppy disk even without the ejector 14 and tension plate 9. It can also be said that it shows an example different from the example shown.

FIG. 1 shows the state where the floppy disk is not loaded, that is, after the push button 6 is pressed and the floppy disk is removed.

In this state, the trigger 7 is biased by the spring 13 and rotates clockwise in the figure, so that the engaging portion 7a of the trigger 7 rotates clockwise in the figure.
This locks the pin 4b at the inner end of the slide lever 4 to hold the slide lever 4 in the pushed-in position. Also, in this state, the ejector 14
Although the ejector spring 15 biases the ejector 15 to maintain a right-rotated posture, the pin 4b of the slide lever 4 and the ejector 14 are not in contact with each other, as shown in FIG. The collet lever 8 is tilted by a spring 18 with the cam 8a side facing down, and a floppy disk 20 is placed between the collet 8b and an opening member (not shown).
It is in a position to allow the insertion of

In this state, insert a new floppy disk 20 from the front bezel 2 side, hold the front edge of the floppy disk 20, and move the falling piece 1 of the ejector 14 in the direction of the arrow 102 as shown in FIG.
4d, the ejector 14 presses the falling piece 7b of the trigger 7 with one abutting edge 14c, and moves counterclockwise against the trigger spring 13 and the ejector spring 15, that is, the arrow 1 in FIG.
Rotate in the direction of 03. And Ijiekta 14
One abutting edge 14c of the floppy disk 20
Ejector 1 until it becomes almost parallel to the leading edge of
4 rotates, the trigger 7 that rotates together releases the locked pin 4b and frees the slide lever 4, and the tension of the spring 10 acts on the rising piece 4d of the lever 4 via the tension plate 9. to move the lever 4 to the right in the figure (second,
Figure 3).

By the way, this tension plate 9 rotates clockwise in the figure under the tension of the spring 10 as described above, and rotates in a direction perpendicular to the moving direction of the slide lever 4 with the roller 9a provided at one end. Since it is configured to press the rising piece 14d of the pin 5, its acting force is weak at the beginning of the rotation when the vertical distance L 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 weaken at the end, so the slide lever 4 receives approximately equal force throughout its entire movement. This movement of the slide lever 4 also causes the damper plates 11a and 11 to alternately move relative to each other in opposite directions on the lever 4.
Sufficient braking is applied due to the viscosity of the lubricating oil interposed therebetween via b (FIG. 4).

For this reason, 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 rotor 4c in contact with the cam piece 8a pushes it up ( FIG. 5) The collector lever 8 is reversed, and the collet 8b provided on the other wing is gently lowered to accurately chuck the floppy disk 20 just inserted into the inlet member directly connected to the drive motor.

Next, when the push button 6 is pressed to take out the floppy disk 20, the roller 4c on the slide lever 4 releases the pressure of the cam 8a, reverses the collector lever 8 by the biasing force of the spring 18, and raises the collector 8b of the other wing. Let them solve the floppy disk 20 chat. On the other hand, the pin 4b of the slide lever 4 is connected to the abutting edge 1 of the ejector 14.
4a while moving toward the center thereof, the recess 14b of the ejector 14 and the engaging portion 7a of the trigger 7
At the point where the floppy disc 2 is rotated to the right by the springs 13 and 15, this torque is applied to the floppy disk 2 which is in contact with the falling piece 14d of the ejector 14.
At the same time, the floppy disk 20 is pushed out toward the front bezel 2 side by pressing the front edge of the floppy disk 20, and at the same time, the floppy disk 20 engages with the engaging portion 7a of the trigger 7 and moves the slide lever 4.
Locks in the pushed position and returns to the initial state.

Note that if the floppy disk 20 is pushed halfway and the loading operation is stopped before the pin 4b of the slide lever 4 and the engagement recess 7a of the trigger 7 are disengaged, the floppy disk 20
Ejector 1 rotated counterclockwise by the leading edge of
4 and the trigger 7, the ejector 14, which is not in direct contact with the pin 4b on the slide lever 4, is rotated clockwise, that is, in the direction of the arrow 104 shown in FIG. 13, by the tension of the ejector spring 15 acting on itself. The floppy disk 20 inserted halfway is pushed out in the direction of arrow 105 shown in FIG. 13 by the torque.

Note that since the slide lever 4 is biased in the direction of the arrow 101 shown in FIG. 10 with a force of about 1 kg by the coil spring 10 shown in FIG.
As shown in the figure, the trigger 7 has a large frictional force between the pin 4b and the engaging recess 7a, and the trigger spring 13 cannot overcome this frictional force.
It was unable to return to the 04 direction and stopped at the position shown in FIG. Note that if the force of the coil spring 10 is increased, the trigger 7 can return in the direction of the arrow 104 in the figure, but in that case, the floppy disk 20 in FIG. 10 should be inserted in the direction of the arrow 102 in the figure. When doing so, the force becomes too strong and there is a risk of damaging the floppy disk 20. By making the trigger mechanism have a dual structure of the trigger 7 and the ejector 14 in this way, even if the insertion of the floppy disk 20 is stopped midway, the floppy disk 20 can be ejected, and the floppy disk 20 can also be ejected. The insertion force can be kept low.

Note that the damper indicated by the reference numeral 11 in the above-mentioned embodiment can be replaced with another speed regulating mechanism consisting of an escape and a pallet lever. , and the collector lever 8 may be provided with a cam follower that comes into contact with it.

[Effects] As described above, according to the present invention, when the manual operation member that is attached to the main body of the device so as to be removable and is biased in the projecting direction is pushed in, the manual operation member drives the floppy disk. Release the clamping action of the member connected to the member,
The trigger member stops the manual operating member at the pushed-in position and displaces the floppy disk at the loading position in the direction of ejecting it, and when loading the floppy disk with the manual operating member at the pushed-in position, the trigger member is manually operated. The member is displaced in the opening direction, and the manually operated member causes the clamping member to perform a clamping action to couple the floppy disk to the drive member, so that loading of the floppy disk is performed without a secondary movement. In addition, the manual operation member that protrudes only when the floppy disk is loaded makes it possible to visually check the loading status, and when the floppy disk is not loaded, the manual operation member is held in the pushed-in position, thereby preventing damage to the device during transportation. This has the effect of preventing various harmful effects.
