Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a floppy disk device, and more particularly to a floppy disk device in which floppy disks are inserted manually and ejected automatically. It is.

BACKGROUND OF THE INVENTION In recent years, florape disk devices have been becoming lighter, thinner, shorter, and smaller. In particular, smaller size and thinner devices have become essential, and as a result, improvements in operability and reliability have become important. An example of a conventional floppy disk will be described below with reference to the drawings. FIG. 4 shows a conventional floppy disk device, in which reference numeral 31 is a floppy disk (hereinafter referred to as a disk), a disk holder for storing a floppy disk 32, and guide bins 33 are fixed at both ends. 34 is a slide plate with guide holes 47 provided at both ends, and a guide bin 3
It is engaged with 3. Further, a projection 44a is provided on the lower surface, and is engaged with a projection 39a provided on the main body 39 by a spring 38, and is pulled in one direction. 35 is a boss;
A plurality of discs 9 are fixed on the disc 9 to slidably guide the slide plate 34, and the upper part also has a shape to position and support the disc 32 at a fixed position. A bent portion 3ab is provided at one end of the slide plate 34, and a knob 36 is fixed thereto. 37 is fixed to the main body 39 by a panel, and has an insertion slot 44 for the disk 32 and an opening 45 through which the knob 36 slides. Reference numeral 41 denotes a regulating plate, one end of which is fixed to the upper surface of the disc holder 31, and the other end of which is slidably attached to a guide pin 4o fixed to the main body 39.

42 is a hook, and one end is a locking part (
The other end has a protrusion 42a, is rotatably attached to a fulcrum pin 46, and is biased in one direction by a spring (not shown).

The operation of the conventional example configured as described above will be explained below. First, to install the disc 32, when the disc 32 held by hand is inserted into the insertion slot 44 of the panel 37, it is stored in the disc holder 311C, and when it is further inserted, it comes into contact with the protrusion 42 & provided on the hook 42, and the hook 42 rotates and slides. The portion that is engaged with the plate 34 will come off. Then, the slide plate 34 is pulled back in the direction of the arrow 43 by the spring 38. That is, the υ guide pin 33 is guided by the guide hole 47, and the disc holder 31 is lowered. At this time, the lower surface of the disk 32 is positioned and supported by the post 35, and the upper surface is pressed by the inner surface of the disk holder 31, completing the mounting of the disk 32. At this time, knob 36
protrudes to position 36a. In this state, disk 32
can be recorded and played back.

Next, to take out the disk 32, the slide plate 34 slides by pushing the knob 36 that protrudes to the position 36a, and the guide pin 33 is guided through the guide hole 47. That is, the disc holder 31 begins to rise, and when the knob 36 is further pushed, the hook 42 rotates and locks the slide plate 34. At this time, the force of a shutter spring (not shown), which is provided on the upper surface of the disk holder 31 and which constantly urges the disk 32 in the direction of the arrow 43, pushes the disk 32 to a certain position, making it possible to take it out.

Problems to be Solved by the Invention However, with such a configuration, if the Freonbie disk device is made smaller and thinner, the disk 32 will become smaller and thinner in terms of operation.
In terms of reliability, ejecting the floppy disk becomes particularly difficult, even when the floppy disk device is recording or playing back.
There was a problem in that if you accidentally took it out, you would have to set it back in again. This is due to the following reasons.

In other words, in terms of operation, the smaller and thinner the disk 32
a panel 37 provided with an opening 45 for guiding insertion;
The distance between the disc 32 and the knob 36 becomes narrow, and when the disc 32 is taken out, when the disc 32 is pushed with a fingertip, the disc 32 comes into contact with the finger and stops at an incomplete position. Also disk 3
2, when attaching or removing the device, there is no space for the fingertips to escape from contact with the panel 37, and the hand is attached to the panel 37.
This makes it difficult to grip the disk 32. In addition, this floppy disk device has two
In many cases, the pedestal is assembled with narrow mounting intervals, making installation and removal even more difficult. In terms of reliability, when the disk 32 is installed, since the knob 36 protrudes from the surface of the panel 37, the operator may accidentally press it and the disk 32 may be taken out carelessly. Furthermore, since the disc 32 can be removed even during recording or playback by pressing the knob 36 as described above, it is difficult to protect the software recorded on the disc 32.

In view of the above problems, the present invention eliminates the ejecting knob and automatically ejects the disc by inputting an external signal when the operator completes the work.

Means for Solving the Problems In order to solve the above problems, the present invention provides a drive source that automatically takes out the disc, and operates this drive source by an external signal to drive the slide plate and raise the disc holder. It is configured so that it can be

With the above-described configuration, the present invention allows the drive source to raise the disc holder housing the disc when the disc is taken out, making it possible to easily take out the disc. Since there are no protruding parts, there is no need to accidentally remove the disc, improving reliability.

It has an opening 2a for easy guidance, and is fixed onto the main body 11 with a screw (not shown). A plurality of bosses 8 are fixed on the main body 11 to pivotally support the slide plate 6 so as to be slidable in the direction of an arrow 17. This boss 8 positions and supports the disk 1 on the main body 11, and has a shape that does not come off the boss 8 within the slidable range of the slide plate 6. That is, the slide plate 6 is engaged with the boss 8, and the slide plate 6 has a long size (6e in FIG. 3) that allows it to slide.

An L-shaped bent portion 6C is formed at one end (panel 2 side) of the slide plate 6, and an opening 2 provided below the panel 2.
b is provided at a position that covers the slide plate 6 when it slides. Reference numeral 4 denotes a disk holder for storing the disk 1 to be inserted, and the disk 1 is provided in such a shape that at least the disk 1 has play when inserted, and guides formed by bending from the slide plate 6 are provided at both ends. A guide pin 5 is fixed so as to engage with the hole 6a. Therefore, when the slide plate 6 slides in the direction of the arrow 17, the guide bin 5 is guided into the guide hole 6a.

In other words, the disc holder 4 is in the upper and lower direction of the free mark 18)
move to. In addition, a regulating plate 1 is provided on the top surface of the disc holder 4.
o is fixed, one end is attached so as to engage with a guide pin 9 fixed on the main body 11, and when the above-mentioned disc holder 4 moves up and down in the direction of arrow 18 by sliding of the slide plate 6, the arrow 17 It moves up and down in a fixed position without moving in the direction of. Furthermore, the guide hole 6a is formed at an angle that allows the disc holder 4 to move up and down smoothly by sliding the slide plate 6.

A locking portion 6 having an elongated portion 12 is formed at one end of the slide plate 6.
d is provided, and this locking portion 6d is connected by a link 13 to a drive source 14, which will be described later. Specifically, the bottle 13a is fixed to one end of the link 13, and the elongated hole 12
The other end is engaged with and connected to the bin 15a of the wheel 16 disposed on the drive source 14. That is, when the wheel 16 rotates, the link 13 is interlocked.

When the drive source 14 is out of order and cannot be driven, the slide plate 6 can be moved from the opening 2b provided below the panel 2 with a rod 3 (see FIG. 2) having at least a smaller diameter than the opening 2b.
By pressing the bent portion 6C formed in the slide plate 6
can be slid. That is, the disc holder 4 containing the disc 1 can be raised.

In addition, in FIG. 1, 7 indicates a protrusion 11a provided on the main body 11.
and a projection 6b provided on the slide plate 6, and biases the slide plate 6 to the left in FIG.

Next, the drive source 14 will be explained based on FIG. 3. The drive source 14 includes a motor 14a, a gear group 14c that transmits the rotation of the motor 14a, a wheel 15 that rotates integrally with the final stage of the gear group 14C, and a protrusion 15b provided at one location of the wheel 15. When the wheel 15 rotates, a piece 17 of the switch 17 attached to the drive source 14
The protrusion 15b is configured to abut against the protrusion 15b, and is fixed on the main body 11. Therefore, in this drive source 14, when the motor 14a is rotated by an external signal, the wheel 16 is rotated, and the link 13 is interlocked. That is, in order to slide the slide plate 6 engaged with the link 13, the disc holder 4 housing the disc 1 is raised, and the disc 1 can be taken out.

Next, other configurations of this device will be explained. 2° is a carriage having a magnetic head capable of recording, reproducing, erasing, etc. on the disk 1 (not shown), and is fixed on the main body 11 and supported by the shirt 20a so as to be slidable in the direction of the arrow 20b. There is. Reference numeral 19 denotes a stepping motor that drives the carriage 2o in the direction of the arrow 20b, and is connected by a thin belt (not shown) so that the amount of drive does not change due to temperature changes. 21 is fixed on the main body 11 by a spindle motor, and has a button 21a that engages with the post 8 provided on the main body 11 and the lower surface of the disk 1 mounted by the disk holder 4 to rotate the disk. It is something.

Next, the operation of loading and unloading a disk will be explained based on FIGS. 1 and 2.

FIG. 1 shows the disc 1 before it is inserted into the disc holder 4, and FIG. 2 shows the disc 1 installed in the main body.

In FIGS. 1 and 2, when the disk 1 held by hand is guided and inserted into the opening 2a provided in the panel 2, it comes into contact with one end of the hook provided on the main body 22. (The following is the same as the conventional example, so it is not shown). The other end of this hook locks the slide plate 6 in a fixed position (in the state shown in Figure 1, and in a position where the disc 1 can be inserted), so when the tip of the disc 1 comes into contact with the series of hooks, The end came off,
The slide plate 6 slides due to the spring force. That is, the disc holder 4 housing the disc 1 is guided by the guide hole 6a and lowered. At this time, since the elongated portion 12 provided at one end of the slide plate 6 also slides, the pin 13a fixed to the link 13 is located at the other end of the elongated hole portion 12.

Here, the lower surface of the disk 1 is positioned and supported by a boss 8, and the upper surface is pressed by a disk holder 4. That is, due to the tension spring 7 and the guide hole 6a having an angular thickness,
It is pressed with the appropriate load and installation is completed.

Next, the extraction operation will be explained based on FIGS. 2 and 3.

In FIG. 3, when an external signal is applied to the drive source 14 to take out the disk 1 mounted on the main body 11, the motor 1
4a rotates, and the wheel 16 is rotated by the gear group 14b. Therefore, the link 13 begins to be pulled, and then the wheel 16 described above in FIG. . That is, the slide plate 6 is pulled and the holder 4 begins to rise.

When the wheel 15 rotates 180Q, the slide plate 6 is locked by a hook (not shown) provided on the main body 11. At this time, the disc holder 4 rises to a position where the disc 1 can be taken out. Then, the disk 1 (not shown) is pushed out by the shutter lever 22 pulled by the spring 23 shown in FIG. The wheel 15 rotates further,
After 366 rotations, the stop switch 17 provided on the drive source 14
The pin 1sb fixed to the wheel 15 comes into contact with the pin 1sb, the motor 15 stops, and the ejection of the disk 1 is completed. At this time, as shown in FIG. 1, the pin 13a fixed to the link 13 and engaged with the elongated hole 12 is located on one side of the elongated hole 12, making it possible to insert the disk 1. .

Next, the operation for removing the disk 1 when the drive source fails will be explained based on FIG. 2.

If the drive source 14 fails and the disk 1 cannot be removed while the disk 1 is attached, a pin 3 with a diameter at least smaller than the opening 2b is inserted into the opening 2b provided below the panel 2, and the slide plate 6 is removed. When the bent portion 6C provided at one end is pushed to the position l, that is, to the sliding range of the slide plate 6, the holder 4 rises and the disc 1 can be taken out.

Therefore, the disk 1 cannot be removed unless the pin 3 is inserted into the opening 2b and pushed.

Effects of the Invention Since the present invention has the above-mentioned configuration, the disc is ejected by operating the drive source based on an external signal, resulting in extremely improved operability. If there is nothing protruding from the surface, the operator will not accidentally remove the disc during recording and playback.

Therefore, it also protects the software on the disk.
