Abstract

PURPOSE:To eliminate clogging of disk by increasing the driving current of a driving motor used in a delivery member by one rank by a current control means for increased torque if there is no signal from a driving detection means which detects driving of the delivery member. CONSTITUTION:A rotating element 32 is rotated by a stepping motor, and disks such as plural medals in a hopper located on the rotating element are carried to the band-shaped part 30b of a placing plate from a disk hole 32a formed in the rotating element 32. The number of disks to be delivered are detected by oscillating of a detection lever 21. If there is no detection signal of a sensor 25 resulting from no action of the detection lever 21 due to clogging medals, the driving current of the stepping motor is increased by one rank for increased torque, thus eliminating clogging.

Description

[Detailed Description of the Invention] Rikan 13 Kyu” Shiya! - This invention provides a disc body that selectively sends out a predetermined number of disc bodies such as medals and coins stored in a hopper in a gaming machine such as a slot machine, a medal lending machine in a game hall, a money exchange machine, etc. Regarding a sending device.

2. Description of the Related Art Conventionally, for example, in a slot machine, a bear-shaped induction motor 1 is used, as shown in FIGS. 8 and 9.
The rotation of the motor 1 is decelerated by a gear head 2 to drive an internal delivery member, and by driving the delivery member, a predetermined number of medals to be stored in the hopper 3 are selectively delivered.

Problem to be Solved by the Invention However, since the drive direction, drive speed, and drive torque of the bear-shaped induction motor 1 cannot be controlled, when medals become clogged, all the medals in the hopper 3 must be removed and the inside inspected. It was very troublesome.

SUMMARY OF THE INVENTION An object of the present invention is, for example, to solve such conventional problems in a disc delivery device such as the above-mentioned slot machine, and to simplify the process when medals become jammed.

Means for Solving the Problems Therefore, for example, as shown in the illustrated embodiments below, the invention as claimed in claim 1 first uses a motor such as a stepping motor 16 to move delivery members such as the rotating body 32, the slider 4, the lever 44, etc. hopper 33 by driving the sending member.
In a disc delivery device that selectively sends out a predetermined number of discs from a drive unit, the drive detection means detects the drive of the delivery member, and when there is no detection signal from the drive detection unit, the drive current of the motor changes. The present invention is characterized in that it is provided with a current control means for increasing the current by one rank.

Furthermore, the invention as set forth in claim 2 provides a method for switching the drive direction of the motor between forward and reverse when there is no detection signal from the drive detection means, instead of the current control means in the disc body delivery device according to claim 1. It is characterized by providing a switching control means.

Then, the motor is activated to drive the sending member, and the hopper 3
A predetermined number of discs are selectively sent out as appropriate, such as 5 discs when there are 3 discs, 10 discs when there are 20 discs, and so on. At this time, when the drive detection means detects the drive of the delivery member and there is no detection signal, the invention according to claim 1 increases the drive current of the motor by one rank using the current control means, and the invention according to claim 2 Then, the driving direction of the motor is switched between forward and reverse by the switching control means.

Big family one Hereinafter, the present invention will be described in detail with reference to the drawings.

1 to 4 show a slot machine which is an embodiment of the invention according to claim 1. The code 10 in the figure is
It is the bottom plate. On the bottom punch 10, there are frame plates 11 facing on both sides.
・Put up 12. Frames 13 and 14 are passed between the frame plates 11 and 12, respectively. The frame 13 has a substrate 1
Screw 5. A stepping motor 16 is fixed to the substrate 15, as shown in FIG. The stepping motor 16 is connected to the drive circuit unit 1 via a lead wire 17.
Connect to 8. The drive circuit unit 18 is fixed to one of the frame plates 11 described above, and a power supply lead-in line 19 is extended from it.

By the way, as shown in FIG. 3, a bracket 20 is attached to the board 15. A detection lever 21 is rotatably attached to the bracket 20, and biased in one rotation direction by a bow tension spring 22. The bracket 20 also has a mounting plate 23.
is attached, and the support plate 24 is attached via the attachment plate 23. A sensor 25 for detecting rotation of the detection lever 21 is fixed to the support plate 24. On the other hand, pin holes 15a are formed in the substrate 15. And those pin holes 1
Pins 26 and 26 are inserted into the pins 5a and 15a from below, respectively, up to the enlarged diameter stepped portion between them.

Then, those bottles 26, 26 are each compressed by the compression spring 2.
Press 7/27 to force it upward. The compression springs 27, 27 are
The lower end is received by the receiving plate 28. The receiving plate 28 has screws 29, 29
to the board] 5.

A medal mounting plate 30 is fixed onto such a substrate 15. The medal mounting plate 30 consists of an annular portion 3°a and a band-shaped portion 30b extending from the annular portion 3°a.

The annular portion 30a is provided with a plurality of foreign matter passage holes 30c through which foreign matter falls, and the belt-shaped portion 3
A guide plate 31 is fixed on 0b. Thus, on the annular portion 30a of such a medal mounting plate 30, a rotating body 32, which is a medal sending member, is provided. The rotating body 32 has a plurality of medal holes 32a on its outer periphery, and its center is connected to the drive shaft of the stepping motor 16 described above. A hopper 33 is provided on such a rotating body 32. A large number of medals are stored in the hopper 33. Then, a connecting ring 34 is connected to the lower end of the hopper 33. The connecting ring 34 covers the annular portion 30a of the medal mounting plate 30 and the outer periphery of the rotating body 32, and covers the belt-shaped portion 30b.
A relief 34a is provided opposite the position where the groove extends.

As a result, when the stepping motor 16 is driven, the rotating body 32 is rotated, and the medals in the hopper 33 are sequentially dropped into the medal holes 32a and placed on the medal mounting plate 30. Then, as the rotating body 32 rotates, it slides on the medal mounting plate 30, and the medal holes 32a...
...Successively hit the medals inside against the pins 26 and 26.

Then, it is guided by the guide plate 31 through the relief 34a of the connecting ring 34, guided onto the band-shaped portion 30b of the medal placement plate 30, and sent out by centrifugal force. The number of medals to be sent out is selectively determined as appropriate by controlling the driving time of the stepping motor 16. However, in order to ensure greater accuracy, the detection lever 21 is rotated by the medal being sent out.
The rotation of the detection lever 21 is detected by a sensor 25 to count the number of sent medals, and if there is a shortage, the stepping motor 16 is further driven by that amount.

Incidentally, in the illustrated slot machine, the drive circuit unit 18 performs control as shown in the flowchart of FIG. 5, for example. That is, when the number of medals is selected in step S1, a drive command is issued to the stepping motor 16 in step S2, and a drive command is issued to the stepping motor 16 in step S3.
The rotation of the rotary body 32 is detected by a drive detection means provided inside,
If the motor does not rotate, the process returns to step S1, and a current one rank higher is applied to the stepping motor 16. When the stepping motor 16 rotates, it is confirmed that an OFF signal has been received in step S4, and the driving of the stepping motor 16 is stopped. Step S
If the OFF signal cannot be confirmed in step 4, the process returns to step S2, and when the unconfirmed state has elapsed for a certain period of time, the process returns to step S1, and a current one rank smaller is applied to the stepping motor 16.

When the step motor 16 is controlled in this manner, when the rotation of the rotary body 32 is stopped due to, for example, deformation of the medal, defective size, or foreign matter entering the device, the rotational torque is gradually increased and the rotation of the rotary body is stopped. 32 may be rotated.

In the illustrated embodiment described above, a case is shown in which a drive detection means for detecting the drive of the sending member and a current control means for increasing the drive current of the stepping motor 16 by one rank when there is no detection signal from the drive detection means are provided. . However, instead of the current control means, a switching control means for switching the driving direction of the stepping motor 16 between forward and reverse is provided, and when the rotating body does not rotate, the driving direction of the stepping motor 16 is controlled to be switched between forward and reverse several times, and the rotation The body 32 may also be rotated.

Now, in the embodiment described above, the rotating body 32 is rotated by the stepping motor 16, and the hopper 3 is rotated by the rotation of the rotating body 32.
3 shows a case where a predetermined number of medals are sent out. However, as shown in FIG. 6, for example, the present invention transmits the driving force of the stepping motor 16 via the piston rod 40 to reciprocate a slider 41, which is a delivery member, and by the reciprocating movement of the slider 41, Sequentially pushes out disc bodies such as medals that have fallen from the hopper 33 onto the medal placement plate 42,
The present invention can also be applied to a disk delivery device configured to selectively send out a predetermined number of disks as appropriate.

Note that the reference numeral 43 in FIG. 6 is a vibration vibrator.

Further, in the present invention, as shown in FIG. 7, for example, a lever 44, which is a sending member, is rotated by a stepping motor 16, and medals and the like are dropped from a hopper 33 onto a medal mounting plate 45 by the rotation of the lever 44. The present invention can also be applied to a disc delivery device configured to sequentially extrude discs and selectively deliver a predetermined number of discs as appropriate. Note that the reference numeral 46 in FIG. 7 also represents a vibration vibrator.

Furthermore, although not shown, the present invention can also be applied to a disc delivery device configured to drive a belt, which is a delivery member, with a stepping motor, and selectively send out a predetermined number of discs from a hopper by driving the belt. Can be applied.

Effects of the Invention Therefore, according to the invention described in claim 1, the drive detection means detects the drive of the delivery member, and when there is no detection signal, the current control means increases the drive current of the motor by one rank to increase the torque. However, according to the second aspect of the invention, the drive detection means similarly detects the drive of the delivery member, and when there is no detection signal, the switching control means switches the drive direction of the motor between forward and reverse. When the body becomes clogged, the clog can be cleared, and the process can be simplified by eliminating the need to remove the disk body in the hopper.
