[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a coin counting device equipped with a coin detection device that checks the material of coins introduced into a coin passage.

(b) Conventional technology Conventionally, a coin detection device is provided to check the material of the coin introduced from the rotary disk into the coin passage, and when this coin detection device detects a counterfeit coin, it outputs a signal.
A coin counting device configured to eliminate such counterfeit coins is known, and is disclosed in, for example, Japanese Utility Model Application No. 57-6703.

(c) Problems to be Solved by the Invention Since the coin detection device in the prior art is configured to electrically analyze and check the material of the coin, the device is complicated and expensive. Furthermore, when a different denomination signal is output, the shutter provided at the bottom of the stacking tube is opened to release the counterfeit coins, which may result in genuine coins being released as well.

In view of the above, the present invention provides a device that can easily and reliably remove only counterfeit currency with a simple and inexpensive configuration.

(d) Means for solving the problem Explaining based on an embodiment, the magnet 1 is provided oppositely on the coin passage 4 near the coin outlet 8.
2, a prevention member 13 that is interposed between the magnet 12 and moved to attract it when a magnetic counterfeit coin conveyed through the coin passage 4 is attracted to the magnet 12; A push button 10 moves a prevention member 13 so that the attracted counterfeit coins separate from the magnet 12 and fall into the coin extraction port 8, and the counterfeit coins are attracted to the magnet 12 by being operated by the movement of the prevention member 13. When the counterfeit coin is separated from the magnet 12, a stop signal is output to stop the drive of the rotary disk.
The coin detecting device includes a stop signal generating device 16 for stopping signal output, and a coin detecting device in which the magnet 12 extends long in parallel with the coin path 4 direction.

(E) Effect The present invention is designed to attract magnetic counterfeit coins by providing a magnet in the coin passage so as to extend parallel and long along the direction of the coin passage, and when the magnetic counterfeit coin is attracted to the magnet. Stop the drive of the rotary disk,
By separating the magnetic counterfeit coins from the magnet and discharging them to the coin takeout port, the rotary disk can be driven again and the material of the coin can be checked.

(f) Examples Examples will be described below in detail based on the drawings. FIG. 1 is an external view of the coin counting device A when viewed from above. 1 is the machine frame of the coin counting device, and this machine frame 1
A rotary disk 2 having an appropriate frictional force is provided on the upper surface of the rotary disk 2 so as to be rotated in the direction of the arrow by a drive device (not shown) such as a motor. Coins C are blown toward the outer circumferential surface of the rotary disk by the centrifugal force of the rotary disk 2, and the coins C are slid into contact with the coin guide members 3 and aligned in the coin passage 4 described below.
be led to. 4 is the above-mentioned coin passage, and the coin passage has a handle (not shown) that is operated according to all types.
It is formed of a guide plate 5 interlocked with the guide plate 5 and sliding pieces 6 facing each other in such a manner as to change the gap between the guide plate 5 and the guide plate 5. 7 is a coin ejecting port 8 in which the coins guided into the coin passage 4 are pressed from above.
The transfer device 7 is composed of a pair of rollers and an endless belt stretched between the rollers, and one of the rollers is driven by the drive device (not shown). It's getting old.

Therefore, although not shown, the coins transferred one by one by the transfer device 7 are engaged with a star wheel rotating at a certain angle, and the rotation of the star wheel is counted by a counter or a proximity switch. You can easily check this. Reference numeral 9 denotes a counterfeit coin detection device which detects counterfeit coins made of iron or the like when the coins C' transferred by the transfer device 7 contain such counterfeit coins. The device 9 is mounted in such a manner that a confirmation press button 10 projects upwardly above the coin passage 4 between the rear portion of the transfer device 7 and the coin outlet 8.

FIG. 2 shows the construction of the counterfeit currency detection device 9, which is comprised of a combination of a magnet 12, a prevention member 13 made of a flat plate, and a stop signal generator made of a micro switch 16, etc., as described below. So 11
is a housing that constitutes a part of the counterfeit currency detection device 9, and on the inner wall surface of the housing there is a member that prevents counterfeit cargoes made of iron or the like from being transferred to the lower surface of the housing, which will be described later. A magnet 12 that attracts the coins 13 while pushing them upward is arranged longitudinally in parallel with the coin passage 4. That is, as shown in FIG. 3, it is fixed to the lower wall of the housing in such a manner that it extends long and parallel to the coin passage 4 direction. Reference numeral 13 denotes a prevention member that prevents the counterfeit currency from being directly attracted to the magnet 12. The prevention member 13 is made of a flat plate having a slightly larger plane than the magnet 12. The coins C are suspended from the fitted shaft member 14 to such an extent that the flow of coins C transferred to the coin passage 4 is not hindered. On the other hand, the above-mentioned confirmation press button 10 is fixed to the upper end of the shaft member 14, and an elastic member 15 is wound around the shaft member 14 between the confirmation press button 10 and the housing 11. It is provided. Reference numeral 16 denotes a prevention member 13 that is pushed up when the magnet 12 attracts counterfeit goods.
This stop signal generating device is composed of a micro switch, etc., which outputs a stop signal to the aforementioned drive device (not shown) in conjunction with the above-mentioned drive device (not shown).

In the above configuration, next, Figures 4 and 5
The operation of the present invention will be described using figures.

First, the coin C sent out from the rotary disk 2 is passed through the coin passage 4 by the above-mentioned transfer device 7 to the coin outlet 8.
transported in the direction. In this process, if a counterfeit coin made of iron or the like is mixed into the transferred coin C', the counterfeit coin detection device 9 attempts to adsorb the counterfeit coin, but at this stage, the rotary disk 2 is still in contact with the counterfeit coin. Since no stop signal is issued to the driving device (not shown), the counterfeit coins are being transported in the direction of the coin outlet 8. However, the counterfeit currency detection device 9 related to the device of the present invention
Since the magnet 12 is provided longitudinally with respect to the coin passage 4 as described above, the magnet 1
2 will not deviate from the detection range even if it is moved slightly in the direction of the coin outlet 8 until the counterfeit coin C'' is picked up in the state shown in Fig. 4. That is, the detection range is
There is no possibility that the material will be transferred beyond the enclosure and become unable to be absorbed. On the other hand, at this time, the actuator member 17, which is a part of the stop signal generating device 16, is pushed upward in conjunction with the preventing member 13, so at this point, the stop signal generating device 16 detects counterfeit currency. Device 9 is counterfeit cargo
C'' is detected, a stop signal is output to a drive device (not shown) that drives the rotary disk 2, and the rotary disk 2 is stopped.

Therefore, the user of these coin counting devices A, upon seeing these stopped states, assumes that counterfeit coins C'' are mixed in the coins and removes these counterfeit coins from the counterfeit coin detection device 9. In order to do so, the confirmation push button 10 is pressed downward.Then, the counterfeit coin C'', which is attracted to the magnet 12 made of a magnet or the like through the prevention member 13, will move in the shape of an arrow as shown in FIG. The coins fall in the direction of the coin outlet 8 shown by . Therefore, after confirming these fallen coins, the user should subtract -1 from the contents counted by the counter or proximity switch, etc. to obtain accurate counting information, assuming that the contents include counterfeit coins. I can do it. On the other hand, stop signal generator 1
6, the prevention member 13 returns to its original position by pressing the confirmation press button 10, so the actuator member 17 also returns to its original position. Therefore, since the output of the stop signal is erased at this point, the user can restart the coin counting operation by operating the start switch (not shown) again.

(g) Effects of the invention The present invention provides a magnet in the coin passage so as to extend parallel and long along the direction of the coin passage to attract magnetic counterfeit coins, so that the magnetic counterfeit coins are attracted to the magnet. Then, the drive of the rotary disk is stopped,
By separating the magnetic counterfeit coins from the magnet and ejecting them to the coin outlet, the rotary disk can be driven again and the material of the coin can be checked, so it has a simple and inexpensive structure. Only counterfeit coins can be easily and reliably removed.
