Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floppy disk feed control method for flexible sheet media in a floppy disk device with autofeed, and in particular, when an error occurs during data processing, the floppy disk is The invention relates to a mechanism for discharging water from the body.

In such a floppy disk device, when the load switch is turned on, the reversible motor moves the feed roller forward and reverse, ejecting the floppy disk from the data processing section and returning it to the stacker, and also transporting the floppy disk in the hopper to the data processing section. The computer is configured to send and process data.

In addition, there are cases where a problem occurs during the feeding operation of a floppy disk and the floppy disk stops midway and is removed by the operator, or when an error occurs during data processing and the floppy disk is inserted into the data processing unit. When ejecting a floppy disk that is currently in use, the feed roller, floppy disk lifter, drive holder, etc. are operated to return to their normal positions by turning on the unload switch, or the lid of the data processing section is removed. The pi disk is now ejected. By the way, when the conventional unload switch is turned on, the feed roller moves forward and reverse to eject the floppy disk from the data processing section and feeds another floppy disk from the hopper, just as in the case of the load switch. Therefore, as mentioned above, if you return each component to its original normal position after a problem occurs, or if an error occurs during data processing and you only eject the floppy disk, other floppy disks may be removed from the hopper. It was necessary to remove the hopper before turning on the unload switch to prevent it from being fed to the processing section. However, since the hopper removal operation when the unload switch is operated is not specifically instructed, it is sometimes forgotten, and this poses the problem that it is difficult to always perform the above-mentioned operation accurately. Ta. The present invention was proposed to solve this problem, and when the unload switch is turned on, the feed roller is rotated only in the direction in which the floppy disk is ejected from the data processing section, and the floppy disk is ejected from the hopper. This invention provides a floppy disk foot control method that prevents floppy disks from entering a data processing section.

The present invention will be explained below with reference to the embodiments shown in the drawings. In FIG. 1, a floppy disk device includes a hopper 2 and a stacker 3 for storing floppy disks 1, which are arranged adjacent to each other and separated by a separator 4. A feeding mechanism 5 is provided in between, and a data processing section 6 for reading and writing from and to the floppy disk is provided behind the feeding mechanism 5.

The feeding mechanism 5 includes a pair of feed rollers 7 disposed opposite to each other,
One of the feed rollers 7 of 8 is driven by a reversible motor 9 via a belt 10, and a pick-up member 12 having a stop lever 11 coaxially with the other feed roller 8 drives the aforementioned belt 10. The stopper lever 11 and the stopper pins 13 and 14 are provided so as to reciprocate for a predetermined distance in contact with each other in the wound state, and the pick-up member 1 picks up the end of the floppy disk 1 when feeding the floppy disk from the hopper 2.
2 and moves between feed rollers 7 and 8. The upper end of the separator 4 is swingably supported, and when the separator 4 rotates in the clockwise floppy disk feeding direction in conjunction with the rotation direction of the feed roller 7, it is positioned on the left side as shown by the solid line, and when the separator 4 rotates in the clockwise floppy disk feeding direction, When rotating in the disk ejection direction, it swings to the right as shown by the chain line. The data processing unit 6 is the rotary shaft 1 of the motor 15.
The rotation of cams 17 and 18 attached to cams 6 closes the holder 19 to rotatably hold the floppy disk, or opens it to release the holder 19, and a lifter 20 lifts the floppy disk 1 when the floppy disk is ejected. It is provided so as to be sandwiched between feed rollers 7 and 8.

Further, the rotating shaft 16 of the motor 15 is equipped with a cam 26 for stopping the rotation of the motor 15, which is equipped with a micro switch or the like.
A stepped cam 21 including a position detector 22 is attached, and by operating a relay circuit 23 using two types of signals from the position detector 22, the reversible motor 9 is rotated in the forward and reverse directions. Further, the motor 15 is rotated by operating a relay circuit 25 with a signal from a control section 24, and a signal is sent from the control section 24 to the aforementioned relay circuit 23 to detect the position. It is connected so as to cut off the reverse rotation signal of the motor 9 from the motor 22. With this configuration, when a signal is issued from the control unit 24 during normal operation by turning on the load switch, the relay circuit 23 operates to control the motor 1.
5, together with the rotating shaft 16, the cams 17, 18, 21, 26
rotates.

Then, first, the holder 19 in the data processing section 6 is opened by the cam 17 to free the floppy disk, and then the floppy disk 1 in the data processing section 6 is lifted up by the cam 18 together with the lifter 20, and its upper end is passed to the feed rollers 7 and 8. It is made to be sandwiched between. Also, the position of the cam 21 at this time is detected and the position detector 22
When the relay circuit 23 is operated by the signal generated from The floppy disk 1 is ejected and stored in the stacker 3. When the floppy disk is ejected in this manner, the cam 21 and the like rotate exactly half a rotation, and the position detector 22 generates a reverse rotation signal different from that described above. Then, the feed rollers 7 and 8 are reversed, and the roller 7 rotates clockwise and the roller 8 rotates counterclockwise, and the separator 4 is positioned to the left of the solid line, and the pick-up member 12 is further rotated a predetermined distance to pick up the hop. 2
Place the end of the floppy disk 1 on the feed rollers 7 and 8.
As a result, the floppy disk 1 in the hopper is sandwiched between the feed rollers 7 and 8 and fed to the data processing section 6. When the floppy disk 1 reaches a predetermined position in the data processing section 6, the floppy disk 1 is placed in the holder 1.
9 closes and holds the floppy data star 1 rotatably,
In this state, data processing such as reading and writing is performed. By the way, if an error occurs during data processing and you want to eject the floppy disk 1 from the data processing section 6,
When the unload switch is turned on, the motor 15 rotates the cams 17, 18, 21, and 26 in the same manner as described above, and the feed roller 7 is rotated counterclockwise by the forward rotation signal from the position detector 22. The floppy disk 1 of the data processing section 6 is ejected to the stacker 3.

Then, a reverse rotation signal is generated from the position detector 22, but at this time, a signal is input from the control section 24 to the relay circuit 23, which cuts the signal from the position detector 22 and returns the output of the relay circuit 23 to its original state. to be held in place. Therefore, in this case, even after the floppy disk 1 is ejected from the data processing unit 6, the feed rollers 7 and 8 continue to rotate counterclockwise and clockwise, respectively, and the pickup member 12 and separator 4 do not operate at all. Therefore, even if the hopper 2 is installed with the floppy disk 1 stored inside, the floppy disk 1
will no longer be sent. In addition, if a problem occurs during the above-mentioned floppy disk ejection and feeding operation and the floppy disk stops midway and is removed by the operator, if the unload switch is turned on after removing the floppy disk, When the floppy disk 1 is not fed from the hopper 2 and the data processing section 6 is empty, each section moves in the same manner as described above, whereby each section is reset to its original normal initial position. As explained above, according to the floppy disk foot method of the present invention, when the unload switch is turned on, the rotation direction of the feed rollers 7 and 8 is automatically restricted to the floppy disk ejection direction, and the pick-up member 12 and separator 4 do not operate at all. Even if the hopper 2 is attached, the floppy disk 1 is not fed out, so there is no need to remove the hopper 2 as in the conventional case.

Therefore, problems such as erroneous floppy disks not being ejected smoothly due to operator's incorrect operations are completely eliminated, and such operations are always performed accurately by switch operation, and at the same time, the operator's It also becomes very easy to operate.
