DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an automatic ejecting device for a flat plate-like object, and particularly for an automatic feeding mechanism for a flexible magnetic disk recording medium such as a floppy disk. Of the flexible magnetic disk recording medium of FIG.

[Prior Art] A floppy disk automatic feeding mechanism includes an automatic ejecting device for taking out the floppy disks one by one from a hopper for stacking and storing the floppy disks to be fed.
The floppy disk taken out is composed of a transport mechanism including a plurality of pairs of rollers for transporting the floppy disk to the drive device. FIG. 3 is a side view showing an example of an automatic ejecting device for taking out the floppy disks to be supplied to the driving device one by one from the hopper.

The gate block 27 constitutes one side surface of the hopper 10, and is the second floppy disk 20 located from the bottom.
It has a predetermined height from the position of B. A separator 28 is provided on the bottom side 27A of the gate block 27 with a gap slightly larger than the thickness of the floppy disk 20, and this gap serves as a gate opening 270. Hopper 1
When the floppy disk 20 is taken out from 0, one end of the lowermost floppy disk 20A enters the gate opening 270.

The picker 33 is the lowest floppy disk from the hopper 10.
It rotates when the 20A is taken out. The picker 33
FIG. 4 shows an example of a front view of the portion viewed from the separator 28 side. The pickers 33 are provided in pairs on both outer sides of the feed rollers 11 of the roller shaft 13 at intervals substantially the same as the lateral width of the floppy disk 20. The picker 33 has an arc portion 33- that protrudes below the thickness of the floppy disk 20A with respect to the outer circumference of the feed roller 11 corresponding to each picker 33-.
Have one. Further, the picker 33 is provided with an extruding portion 33-3 having a straight portion from a predetermined position of the arc portion 33-1 toward the center of the circle to a portion deeper than the outer periphery of the feed roller 11. When the floppy disk 20 is taken out from the hopper 10, the picker 33 rotates in the direction of the arrow P to push out the pushing portion 33.
Floppy disk 20A located at the bottom by -3
The other end of the floppy disk 20A is pushed, and one end of the floppy disk 20A enters the gate opening 270 between the gate block 27 and the separator 28.

The separator 28 is provided so as to be rotatable by a predetermined angle with the support shaft 25 as a fulcrum, supports a part of the lower surface of the floppy disk 20A, and moves downward in conjunction with the push-out rotation of the picker 33 via the link portion 21. The floppy disk 20A, which has partially entered the gate opening 270, is guided to a predetermined discharge path (that is, between the feed roller 11 and the driven roller 24 below it) along with the downward movement. On the outside of the separator 28, a convex portion 28B is provided as a stopper so that the floppy disk 20A does not jump out when the floppy disk 20A is inserted into the gap between the gate block 27 and the separator 28.

The feed roller 11 is provided inside the picker 33 in a pair with the same roller shaft 13, and is rotated by a control mechanism so that the floppy disk 20A is sandwiched between the driven roller 24 and the corresponding driven roller 24 and ejected to the ejection path. To do. Roller 24
The roller shaft 19 is provided at both ends corresponding to the feed roller 11.

[Problems to be Solved by the Invention] However, in the conventional floppy disk automatic ejecting apparatus as described above, since the gate opening 270 is always open, for example, as illustrated in FIG. 3, even when not ejecting. The bottommost floppy disk 20A has a gate opening 2
The floppy disk 20A may be slipped into the disk 70, so that when the floppy disk 20A is to be ejected, the end of the second floppy disk 20B from the bottom is also the push-out portion 33-3 of the picker 33.
The floppy disk 20B is deformed by being pushed by. Or, an accident may occur such that the floppy disk gets caught and becomes stuck. There was a problem.

The present invention has been made in view of the above points, and an object of the present invention is to provide an automatic ejecting device capable of surely ejecting flat-plate-like objects such as floppy disks housed in a hopper from the lowermost layer one by one. Is.

[Means for Solving the Problems] An automatic ejecting device for flat objects according to the present invention includes a hopper for stacking and accommodating flat objects to be ejected, and a flat object at the lowermost layer of the hopper on one side side. From the opposite side to the other side of the pushing member, a gate opening provided on the side of the other side for allowing the other side of the pressed flat plate to enter, A discharge path provided below the pushing member and provided below the gate opening,
Further, it is rotatable, and supports the flat plate-shaped object in which the other side portion has entered the gate opening, rotates the supported flat plate-shaped object in association with the rotation, and the flat plate is rotated by this rotation. The separator member that moves the one side of the shaped object downward to guide it to the discharge path, and the linking between the extruding member and the separator member is performed, and the separator member is interlocked with the extruding operation of the extruding member. A link member for rotating; and a gate member that normally closes the gate opening, opens the gate opening when the pushing member pushes the flat object, and allows the flat object to enter. It is characterized by doing.

[Operation] Since the gate member is provided in relation to the gate opening, the gate opening is normally closed by the gate member, and the flat plate-like object in the lowermost layer of the hopper can be prevented from entering the gate opening. Therefore, it is possible to prevent the end of the flat plate-like object of the lowermost layer from slipping into the gate opening, and prevent the second flat plate-like object from the bottom from slipping into a position where it abuts on the pushing member. On the other hand, at the time of discharging, the gate member opens the gate opening when the flat member is pushed by the pushing member, so that the flat member of the lowermost layer of the hopper is allowed to enter the gate opening, and the separator member By the action, the flat plate-like object is guided to a predetermined discharge path.

In this way, it becomes possible to reliably discharge the flat objects such as the floppy disks stored in the hopper one by one from the lowermost layer.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a side view showing an example of parts of a gate block 27, a gate opening 270, a separator 28, and a swing arm 50 in a floppy disk automatic feeding mechanism to which the automatic flat object discharging device according to the present invention is applied. . The swing arm 50 corresponds to the gate member.

An example of the entire structure of this floppy disk automatic feeding mechanism is shown in FIG. The same reference numerals as those in FIGS. 3 and 4 serve the same functions. This feeding mechanism is roughly classified into a floppy disk 20.
A hopper 10 for storing the hoppers, a separator 28 and a picker for taking out the floppy disks 20 one by one from the hopper 10.
A discharging device including 33 and the like, a conveying mechanism including a plurality of pairs of rollers for supplying or discharging the floppy disk 20 taken out from the hopper 10 to the driving device 5, and the supplied floppy disk 20. The drive device includes a floppy disk drive unit 5 for reading or writing various data, and includes a control device (not shown).

In the swing arm 50, the tip portion 50A has a separator 28.
Is provided so as to close the gate opening 270 between the support portion 28A of the gate block 27 and the bottom portion 27A of the gate block 27.
It is possible to swing around. A tension spring 52 having a predetermined tension is attached between a predetermined portion inside the swing arm 50 and a fixed portion 53 of the present apparatus. By being biased by the spring 52, the tip portion 50A of the swing arm 50 normally closes the gate opening 270 and holds the end portion of the floppy disk 20A. On the other hand, when the floppy disk 20A is taken out of the hopper 10, the floppy disk 20A is pushed by the end of the floppy disk 20A and pivots clockwise in the drawing to open the gate opening 270, and the floppy disk 20A is inserted into the gate opening 270. Allow the edges to enter. Of course, the tension of the spring 52 acting on the swing arm 50 is larger than the slipping force acting on the floppy disk 20A, and the floppy disk is ejected at the time of ejection.
Push-out part 33-3 of picker 33 which acts on the other end of 20A
It is smaller than the pressing force by.

The operation of each part in the above configuration is as follows.

In FIG. 1, when a force that is displaced in the arrow Z direction naturally acts on the floppy disk 20A located at the lowermost layer of the hopper 10, one end of the floppy disk 20A has one end of the swing arm 50. Since it is blocked by 50A, the end of the floppy disk 20A does not slip into the gate opening 270. Therefore, since the other end of the second floppy disk 20B from the bottom does not come into contact with the push-out portion 33-3 of the picker 33 during ejection, the floppy disk 20B can be protected.
It becomes possible to take out exactly one by one from the hopper 10.

To remove the floppy disk 20 from the hopper 10,
Since the end of the floppy disk 20A that comes into contact with the push-out portion 33-3 according to the rotation of the picker 33 is pressed with a force larger than the tension of the spring 52, the tip end of the swing arm 50.
When 50A is pushed, it rotates clockwise in the figure and the gate opening 270
To allow the end of the floppy disk 20A to enter the gate opening 270. At the same time, the separator 28 is rotated downward through the link portion 21 in conjunction with the push-out rotation of the picker 33, and accordingly, the other end of the floppy disk 20A whose one end has entered the gate opening 270 is directed downward. It rotates, is guided between the feed roller 11 and the roller 24, and is discharged. The ejected floppy disk 20A is transferred to the transport path 17
Through the feed roller 22 and the driven roller 23, and further reaches the floppy disk drive unit 5.

The gate member is a spring 52 as in the illustrated embodiment.
It is not limited to the swing arm 50 biased by the above, and may be, for example, a solenoid biased appropriate gate opening / closing structure or any other appropriate structure.

In this embodiment, the automatic drive mechanism for the flexible magnetic disk recording medium or the like for the disk drive device is described, but the material to be fed is not limited to the floppy disk, and an appropriate flat object can be used for any device. It may be discharged.

[Advantage of the Invention] As described above, according to the present invention, since the gate member is provided in relation to the gate opening, the gate opening is normally closed by the gate member, and the flat plate-like object at the bottom layer of the hopper is opened. You can prevent them from getting inside. Therefore, it is possible to prevent the end of the flat plate-like object of the lowermost layer from slipping into the gate opening, and prevent the second flat plate-like object from the bottom from slipping into a position where it abuts on the pushing member. On the other hand, during discharging, the gate member opens the gate opening when the flat member is pushed by the pushing member, so that the flat member in the lowermost layer of the hopper is allowed to enter the gate opening, and the separator member By the action, the flat plate-like object is guided to a predetermined discharge path. In this way, it is possible to prevent the second flat plate positioned from the bottom from being pushed out by the pushing member, prevent accidents such as breakage of the flat plate, and remove the flat plate such as the floppy disk stored in the hopper. It has various excellent effects that the sheets can be surely discharged one by one from the lowermost layer.
