DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin processing device that is capable of processing multiple types of coins with different diameters, thicknesses, paulownia qualities, etc. on a single coin track.

In public telephones, etc., inserted coins are guided to a coin track constructed on a circuit board, and a series of processes such as coin sorting, accumulation, storage, and return are carried out. is set for every 4.3 coins, so one coin orbit could only handle a single type of coin. For this reason, in a public packing machine that uses several types of coins with different diameters, thicknesses, and materials, a dedicated coin track must be used for each coin.
.

Therefore, the structure was extremely complicated and thick.

This invention was developed based on the above-mentioned circumstances, and its purpose is to provide a single coin track on a single substrate with multiple types of coins having different diameters, thicknesses, grains, etc. It is an object of the present invention to provide a coin processing device capable of processing coins.

An embodiment of the present invention shown in the drawings will be described below, taking as an example a case in which it is applied to a public telephone.

Figure 1 is a conceptual diagram showing the outline of the configuration of a coin processing device used in a public telephone that can handle multiple types of coins. (DW: Coin track, 1 is a coin slot track provided directly below the coin slot 2, 1B is a coin sorting track that guides coins diagonally downward following the coin slot track, and 1C is a coin sorting track that is installed directly below the coin slot 2. This shows the coin accumulation trajectory for temporarily accumulating coins that have passed through the coins.Coin slot 12 can be used. Therefore, the number of coins that can be used from the coin slot 2 is set to +11111i K slot trajectory IA,
Pass through the coin sorting track 1B and insert into the coin accumulation track 1C Jt
li4 [Personally selected.

The board 3 which was tilted and killed inside the housing of a public telephone with one coin track, the track forming &4 attached to the bottom side of this board &3, and the board 3 (also (bow: track forming plate 4) attached to the board 3) The rail 5 is constructed by a rail 5 which has a shape of f'.

As shown in FIG. 2, on the upper surface side of the board 1, an input flapper 6 and a track forming plate 4 are provided with row panels 6a and 4a, respectively.
A rotational force is applied in the direction of approaching the substrate 3 by t.
It is rotatably mounted.

A hook interlocking mechanism is provided on the bottom side of the board 3, and the hook interlocking mechanism is interlocked depending on whether the handset is placed on the handset or the handset #1. 1, the coin track 1 is released, and when the handset is raised, the track forming plate 4 and the input flapper 6 are rotated in the direction approaching the base plate 1 by the rotational force of the coil springs 4a and 6a. A coin trajectory 1 is formed between the board 1 and the board 1.
It is designed to form a

3 to 6 show the specific structure of the hook interlocking mechanism 8. FIG. That is, the hook interlocking mechanism 8 is attached to the mounting base 9 on the board 3.
It is composed of a hook interlocking member 10 and an operating member 11 which are rotatably attached via a hook linking member 10 and an operating member 11.

The hook interlocking member 10 has a leg portion 10b extending downward from both ends of a base portion 10a, and an arm portion 10c extending in a direction away from the board 3. A rotational force is applied in the direction of separating from the substrate 3. The roller at the tip of the arm 10c comes into contact with a hook mechanism that moves up and down as the handset is raised and hung.When the handset is hung, the coil spring 12 is activated by the weight of the handset.
The hook interlocking member 10 rotates in a direction in which the arm portion 10c is pushed down against the rotational force.

The actuating member 11 has a side plate 11b extending upward at one end of the base 11a, and the side plate 11b is provided with an inlet orbit release part for abutting against the roller at the tip of the protruding piece 6a of the base inlet flap flap 6. 11c, and a receiving portion 11 for contacting the tip roller of the leg portion 10b of the hook interlocking portion ladle 10.
Everything will come true. Further, a side plate 11et is provided at the other end of the base portion 11a and extends vertically. This side plate 10e
At the upper end, there is a sorting accumulation track release part '11f with a roller biased at the tip for moving back and forth through the hole 3a and abutting against the track forming plate 4 facing the upper surface side of the hole 3a above the board 3. It extends in the direction of the hole 3a. Also, this side plate 1
At the lower end of 1e, a return stopper 11g for moving the substrate 3 forward and backward through the hole 3b below extends toward the hole 3b.

This actuating member 11 is given a rotational force by a coil spring 13 in a direction in which the return stone 11g moves away from the substrate 3.

Therefore, when the handset is hung, the hook mechanism presses the arm 10c downward and the hook interlocking member 10 rotates against the huge IJJJ force of the coil spring 12, as shown in FIG. 3.4. No. Therefore, the leg portion 10b of the hook interlocking member 10 moves toward the substrate 3, and the pressing force on the receiving portion 11d of the actuating member 11 is released. For this reason, the actuating member 1
1 is rotated by the rotational force of the coil spring 13, and therefore, the input port orbit release part 11c of the actuating part 1 phase 11 rotates the input port flapper 6'ff in the direction away from the board 3, and completely releases the input port trajectory. At the same time, the sorting accumulation orbit release unit 11f
enters the hole 3a of the base plate 3 and rotates the track forming plate 4 in the direction away from the base board 3 to completely release the coin sorting and accumulation track, and the return stock horn 11g exits from the lower hole 3b.

When the transmission/reception is performed, the hook interlocking member 10 is released from the suppression and is moved to the 5.6th position by the force 1 and the rotational force of the coil spring 12.
The leg portion 10 of the hook interlocking member 10 rotates as shown in the figure.
b is the receiving portion 11d of the actuating member 11 in the direction away from the substrate 3.
Press. Therefore, the actuating member 11 has a coil spring 13
As shown in FIG. 6, it rotates against the rotation 111υ force caused by the rotation, and as shown in FIG. The suppression is released, and one input track and one coin sorting and accumulation track 1B are formed. At the same time, the return stopper 11g enters the hole 3blC.

In this way, the coin track 1752 is formed by raising the handset and receiver, and the return stock f11g enters the terminal position fiA1 of the coin storage track 1C, making it possible to store coins.

As shown in FIGS. 1 and 7, the floating rock detection coil T and the U-luck detection coil M1 are mounted on the track forming plate 4 and the substrate 3, respectively, so as to face each other along the coin sorting track 1BIC. . In this installation, the material detection coil M2 and the diameter detection coil D are similarly opposed to each other at a distance of one coin from the position, as shown in Figures 51 and 8, and each forms a track. It is attached to the plate 4 and the substrate 3. As shown in Figure 9, these coils should be mounted close to the rail 5 so that the thickness detection coil T and material detection coil M1 are covered by the regular coin of the smallest diameter, to prevent stiffness. Diameter detection coil D Pumping particle detection coil M2
covers part of the regular coin with the smallest ball and has the largest diameter i
It is positioned slightly away from the rail 5 so that the entire coin is not thrown away by the E coin.

Coin sorting track 1B Changes in the impedance of these coils caused by falling coins are detected by the coin sorting device described later, and the thickness, diameter, and thickness of the coin are detected by the coin sorting device described later.
The quality of the coin is determined, and based on the sorting information for each coin that has been recorded in advance, the appropriateness, inappropriateness, and draw of the coin are determined.

As shown in FIGS. 1 and 10 to 13, the material detection coil M2 and diameter detection coil D of the coin sorting track 1B are installed further downstream from the position, allowing only proper coins to pass through. Window 4b drilled in track forming plate 4 to prevent illegal currency
The device 14 distributes the liquid to the upper surface of the track forming plate 4.
is attached to the back side of the board 3. That is, on the back side of the board 3, a yoke 16, a flat permanent magnet 17, and an L-shaped yoke 18 are attached via a stand 15 in a stacked state, and the L-shaped yoke 18 on the top A sorting electromagnet 19 is attached to one end VC of the iron 18. As for the above-mentioned attachment, an adsorption member 21 attached to the base of an L-shaped distribution lever 20 is rotatably attached to the stand 15.

The sorting electromagnet 19 is not energized when the coin sorting device determines that the coin is an invalid coin, and the tip of the e-shaped member 21 is connected to the yoke 18, the iron core 19a5 of the sorting electromagnet 19, the adsorption member 21, and the yoke 16. In the magnetic path, the magnetic force of the permanent magnet 17 causes the iron core i 9 to
a V (It has been strongly attracted, and as shown in Figure 12, the tip of the lever 20 should enter into the coin sorting track 1B through the window 3c drilled in the base plate 3.) Illegal coins CN falling on the track 1B are removed from the window 4b of the track forming plate 4 to the upper surface side of the track forming plate 4.Then, when the coin sorting section determines that the coins are proper coins, When the discrimination is made, the sorting electromagnet 19 is energized and the permanent magnet 1
7 generates a magnetic flux in the direction of attenuating the attraction force toward the tip of the attraction member 21 in the direction of the iron core 19a, and therefore, although the tip of the attraction member 21 is attracted to the iron core 19a, an extremely small external force is generated. As shown in FIG. 13, the proper coins C1, which have been able to separate from the iron core 19B and have rolled down the coin sorting track 1B, are sorted into the coins 1 and 1 at the tip of the lever 20, as shown in FIG. There is an exit hole in the capital, and the tip is pushed aside to pass through to the window 3c side.

In this way, only the correct coins pass through the coin side l+ and path 1B, but in order to detect this passage, the topmost coin accumulation track 1C following the coin sorting track 1B as shown in Fig. A detection coil 22 for coin pass overflow detection is installed so as to face the
The coil 11 also has the role of detecting when several coins have been accumulated and reached the top of the coin accumulation trajectory 1C, and the coins have been accumulated up to the coil 22 ta.
Then, the coil 22 T4 * one row 1i is also Eυ] 1
The sorting is done by lever 2 so that the coins sent to the coin sorting sulfur and further inserted 'i' are not introduced into the coin accumulation track 1C.
At 0, the coin is removed from the coin sorting track 1B.

On the top side of the board 3 (as shown in Figure 14.15,
Apply force and force 2 so as to apply the upper part of the orbit forming plate 4.
3 is installed, this cover 23 (Z'fmHrl!l
A stand 24 is provided for mounting. A storage electromagnet 26 is attached to one end of the base 24, and the armature 25 is attracted to the armature 25 by a storage signal. In order for the other part 25a to rotate in the direction approaching the cover 23, the storage '11=Goseki 26 is rotatably added in color.A storage stopper 27 is attached to the other end of the base i4. And a stop member 28 is rotatably attached.

The storage stone =-27 has a horizontal portion 27a bent in a substantially L-shape in the direction of the board 3, and is rotated in the direction of entering the coin storage track IC so that the tip of the horizontal portion closes the coin storage opening by the coil spring 29. It is powered. Storage stopper 2
7 has a lug 271 extending to the upper side, and when the housing electromagnet 25 is energized and the armature 25 is attracted, as shown in FIG. The ear piece 27b is pressed by the roller at the tip of the storage stopper 27, and the storage stopper 27 rotates against the rotational force of the coil spring 29, so that the tip of the horizontal portion 27a exits from the coin storage track 1C. There is.

The stop member 28 has a protruding piece 28ak that is bifurcated in the direction of both ends of the storage stopper 27 at the lower part and extends in the direction of the circular hole 4c of the track forming plate 4, and on the opposite side, the stopper member Hole 3 on the outside of 11g
It has a stop protrusion 28b' extending in the b direction. One end of an elastic suppressing member 28c made of a coil spring, rubber, sponge, etc. is attached to the tip of the protruding piece 28a, and the elastic suppressing member 28c enters in the direction of the round hole 4c, and the tip comes into contact with the base plate 3 or the subsequent coin. Compressed. Stop member 2
8, a coil spring 30 applies a rotational force to the tip of the elastic suppressing member 28c and the tip of the stop protrusion 28b in the direction of leaving the coin accumulation track 1C. Projecting piece 28a
A contact piece 28d extending upward is attached to contact the armature 25, and as shown in FIG. 15, the housing electromagnet 26 is energized and the armature 25 is attracted. Then, the contact piece 28d touches the other end 25a of the armature 25.
The stop member 28 rotates against the rotational force of the coil spring 30, and the end of the elastic portion 280 and the stop protrusion 28
The tip of b enters the coin accumulation track 1C.

Therefore, when the storage electromagnet 26 is not energized, as shown in FIGS. 14 and 16(a), the storage magnet 26 is
The tip of the horizontal tNH7a of '27 enters the coin storage track 1C and blocks the coin storage opening, and the protruding piece 23a of the stop member 28
The distal end of the elastic suppressing member 28c attached to K has exited from the round hole 4C of the track forming plate 4, and the distal end of the stop protrusion 28b has also exited from the coin accumulation track 1C. In this state, the first coin C1 that has been transferred and dropped to the coin accumulation track 1C is stopped at the coin storage position A2 by the return stopper 11g and placed on the horizontal part 27a of the storage stone /-P27. The second coin C2 is located at the subsequent position A3, and subsequent coins are sequentially placed in the coin accumulation track 1.
It is accumulated in C.

When the storage electromagnet 26 is energized by the arrival of the storage signal, the armature 25 is attracted, and therefore, as described above, the tip of the elastic pressing member 28C and the tip of the stop protrusion 28b enter the coin storage track 1C, and the horizontal portion 27a 15 and 16(b)), the first coin C1 located at the coin storage position A2 falls into the coin storage opening.

At this time, the two-sheet @ that moves to the subsequent position A3 at the same time!
The load C2 is the elastic suppressing member 28c that has entered the round hole 4c.
The coin C2 is kept in a stopped state by being pressed against the substrate 3 by the tip of the coin C2. Although the center position of the succeeding coin C2 shifts depending on the type of the first and second coins, the elastic suppressing member 28c has a diameter large enough to cover this shift, and the center position of the succeeding coin C2 shifts. can be stopped by pressing it independently.

When the storage electromagnet 26 is de-energized after storage, the storage stopper 27 and the stop member 28 are restored to their original states by the rotational force of the coil springs 29 and 30, respectively, and the horizontal portion 2
7a enters the coin storage track 1C and closes the coin storage position again, and the elastic pressing member 28c of the stop member 28 and the stop protrusion 2
8b is in a state where it has left the coin accumulation track 1C (Fig. 14,
161st kl Ic)). Therefore, the coin C2 that was stopped at the subsequent position A3 by the elastic pressing part 'U' 28c rolls on the horizontal part 27a of the storage stopper 27, advances until it comes into contact with the return stopper 11g, and stops at the coin storage position A2. However, the third coin C3 subsequently advances to the succeeding position A3, and if there are subsequent coins, these also advance sequentially. In this way, each time the storage signal arrives, the succeeding position f*
While A3 coins are temporarily stopped, the coins at storage position A2 are stored one by one from the coin storage opening.

Below the coin storage opening, as shown in FIG.
is installed. The coil 31 also has the role of detecting when the coins stored in the safe (not shown) reach their maximum height, thereby detecting that the safe is full.

Next, the above-mentioned thickness detection coil T and quality detection coil Ml are
, M2.21! A preferred embodiment of a coin sorting device using a diameter detection coil D will be described.

It goes without saying that the present invention may be applied to a coin sorting device for mechanically sorting coins other than this embodiment, as long as it achieves the non-inventive objective.

Figure 17 is a block diagram of a coin sorting device for sorting coins using detection coils T, Mi, D, and M2.

In FIG. 17, 111 is an oscillator that outputs a rectangular wave oscillation signal with a predetermined wave number, and 112 is Ii! +II device.

The thickness detection coil T generates an alternating magnetic field excited by a rectangular wave signal of a constant frequency from a divider 112 which divides the rectangular wave oscillation signal of an oscillator 111, and The n-selection coil M1 is excited by this alternating magnetic field and produces an output voltage. The thickness detection coil T forms a parallel resonant circuit with the capacitor 113, and when there is no coin present, the thickness is detected by tuning to the frequency from the divider 112 and dividing the voltage with the resistor 109. The output voltage appearing across the filter T has increased. Then, when the coin passes between the thickness detection coil T and the material detection coil M1, the impedance of the thickness detection coil T9 changes and the same error occurs, causing the output? l) Pressure decreases. As shown in FIG.
Since the distance h1 is larger than l'L (i.e., the thicker the coin C is), the larger the thickness of the coin C, the greater the output voltage of the thickness detection coil V. descend. Similarly, the material detection coil M1 forms a parallel resonant circuit with the capacitor 114, and the output voltage is maximum when there is no coin and when the coin passes between the thickness detection coil T and the material detection coil M1. , due to a change in impedance of the material detection coil M1, the tuning is lost and the output voltage decreases. Furthermore, the material detection coil M1 is excited by the thickness detection coil T and generates an output voltage (Z), so the material detection coil M1
When a coin passes between the thickness detection coil T and the thickness detection coil T, the output voltage of the thickness detection coil T, that is, the excitation voltage decreases, and the amount of penetration caused by the coin decreases. Due to the difference in a ratio, the alternating magnetic field that reaches the multi-material detection coil M1 changes, and the output voltage generated in the material detection coil M1 decreases.

Similarly, the diameter detection coil D is excited by a rectangular wave signal of a constant frequency from the duplexer 112 to generate an alternating magnetic field, and the diameter detection coil M2 installed opposite to it is excited by this alternating magnetic field. 1. produces an output voltage. A parallel resonant circuit is formed with the diameter detection coil D and the capacitor 115, and the thickness detection coil T is
As in the case of , the output voltage is at maximum. When a coin passes between the diameter detection coil D and the material detection coil M2, the impedance of the diameter horizontal coil D similarly changes, but as shown in FIG. Since the area covering the detection coil D becomes larger, the change in impedance becomes larger, and the output voltage becomes lower.

Similarly, material detection coil M2 forms a parallel resonant circuit with capacitor 116, and the output voltage is maximum when no coin is present, and diameter detection coil D and material detection coil M
When a coin passes between M2 and M2, the material detection coil M2 loses its synchronization due to a change in impedance, and the output voltage decreases. Furthermore, since the material detection coil M2 is excited by the diameter detection coil D and generates an output voltage, when a coin passes between the material detection coil M2 and the diameter detection coil D, the difference in magnetic permeability caused by the coin causes many materials to be used. The alternating magnetic field reaching the detection coil M2 changes, and the output voltage generated at the material detection coil M2 decreases.

The first material detection coil M1 is shown in Figure 9 of tilJ7.
As shown in the figure, since it is provided on the substrate 3 close to the coin and in a position where the coin is covered, when a material with large eddy current loss due to the coin (for example, nickel, iron, etc.) passes through, the material detection coil M1 The resulting output voltage becomes too small to be detected. In order to detect materials that are difficult to detect with the first material detection coil M1, the second material detection coil M2 is mounted on the cover 4, which is relatively far from the coin, as described above, and which is entirely covered by the coin. It is installed in a position where it will not be exposed.

The thickness detection coil T, the diameter detection coil D, the first quality detection coil M1, the second material detection coil M2, and the thickness detection coil M2. '

The change in pressure is converted into a change in DC output voltage by the DC conversion circuit 121K.

The output signal of the material detection coil M1 is a sine wave signal whose level decreases depending on the material of the coin when the coin passes. Similarly, the change in the AC output voltage is caused by the Iα current conversion circuit 122 via the AC amplifier 118i. The hill current IL1 force is converted into a change in voltage.

Similarly, sinusoidal signals are output from the diameter detection coil D and the material detection coil M2, and while the coin passes through the ml between the diameter detection coil D and the material detection coil M2 (indicated by the symbol "mouth" in FIG. 18).

The output signal of -M2 also passes through the flow layer j converter 120 and is converted by the DC conversion circuit 124 into a change in DC output voltage corresponding to the material of the coin. The solid line in FIG. 18(f) shows the output signal of the AC amplifier 119, and the chain line shows the W chi No. 8 of the DC conversion circuit 123.

The shadow # caused by the material of the coin, etc. causes a change in phase as shown in FIG. 19 in addition to a change in the output voltage of the coil. (In Fig. 19, (a) is the thickness detection coil T
(b) shows the sampling pulse from the frequency divider 112, and (C) shows the output signal of the AC amplifier 118. ) Therefore, in FIG. 19, the sampling pulse (b) is generated from the frequency divider 112 at the center point of the pulse width of the signal (a), and the voltage signal sampled and held includes the change in the output voltage of each coil due to the passage of a coin.

When the coin passes through the thickness detection coil T, there is no coin in the diameter detection coil D, so the output voltage of the DC conversion circuit 123 does not drop. Therefore, the variation in the output voltage of the thickness detection coil T when a coin passes is controlled by the differential amplifier 1 using the output voltage of the diameter detection coil D, which does not vary, as the reference voltage.

However, since the thickness detection coil T and the diameter detection coil D use coils and capacitors with the same characteristics and the same temperature coefficient, the output voltage fluctuates significantly due to temperature. Therefore, the differential amplifier 125 provides an output signal from which the temperature variation is removed from the common mode voltage. (d) in Figure 18

While the coin is passing through the diameter detection coil D ticf'i, there is no coin in the thickness detection coil Told, and therefore the output voltage of the DC conversion circuit 121 does not drop. Therefore, the variation in the output voltage of the diameter detection coil D when a coin passes is outputted as a differential voltage signal from the differential amplifier 127 using the unchanged output voltage of the thickness detection coil T as a reference voltage, and as described above, the variation in the output voltage of the diameter detection coil D is outputted as a differential voltage signal. is removed. FIG. 18(g) shows the output signal of the differential amplifier 12T.

Similarly, the differential amplifier 128 provides an output signal from which temperature fluctuations have been removed from the output signal of the DC conversion circuit 124.

L'' (at the rise of the Lf signal, the deterministic m134 is output by the A/D converter 133 to the peak hold circuits 131, 132).
The lowest voltage held in the circuit is transformed into a digital value, and this digital value is input into the judgment circuit 134.

The judgment circuit 134 compares the four types of digital values 1 and 1) with the four preset digital values to judge the authenticity and type of the coin.
39 is sorted for a certain period of time while the coins pass through the lever 20, and a notification is sent to the sorting electromagnet 19. Figure 18 (m)
No. 48 for driving transistor 139 is shown in FIG.

As explained above, the coin sorting device 100 of this embodiment
So, four sho! Out-coiled tongue/Each IIi? The output voltage of each detection coil is sampled and held at a sampling rate synchronized with the oscillation signal that drives the coil, and both the output voltage change and the phase change are measured. Since the captured DC voltage is converted into a DC voltage, the peak value of this DC voltage is converted into a digital value, and the data is compared with preset data for sorting, highly accurate coin sorting can be performed.

Next, the relationship between the coin sorting device 100 and the operations of each of the above-mentioned mechanical parts will be explained.

FIG. 20 is a block diagram of the parts involved in the operation control of the coin processing device of the present invention, and shows the case where it is applied to a public telephone as an example, and the blocks surrounded by double frames are the blocks of the coin processing device of the present invention. It is something.

A detection coil (T) installed facing the sorting track 1B
, Mi, D, M2) fd When a coin inserted by a user passes in front of it, the coin causes an electrical change, and an electrical signal corresponding to the type of coin is sent to the electronic sorting circuit 101.
Send to. The coin sorting device 100 has the detection coil <T
J Mll, D, M2) According to the received electrical signal,
Determine the passiveness, thickness, and material of the inserted coin, and determine the type of coin and whether it is appropriate or inappropriate, for example, whether it is a high-value coin, a medium-value coin, or a low-value coin. Determine whether the currency is a currency or an illegal currency that cannot be used. If the coin is determined to be an evasive coin, the coin information such as its type and how many coins should be properly inserted is stored. An electric signal is sent to the electromagnet 19 to push aside the distribution lever 20 attached to the magnet 19 and allow it to move forward into the storage track IC.

If the currency is invalid, the electrical signal is not sent.

The detection coil 22 for coin pass overflow detection is
It passes through the sorting orbit 1B and is guided into the t' product orbit 1C, /
c This is to count the number of proper coins to 1 and to detect whether or not the accumulation track 1C is filled with the inserted proper coins.
For example, the ON-OFF state is repeated each time the detection coil passes through the 61 plane of the detection coil.

When the number of accumulated coins increases and the detection coil 22 remains covered by the last coin, the analogy remains ON. The coin sorting device 100 detects 0 of the detection coil 22.
The number of N-OFF times is stored as the number of accumulated coins, and when the detection coil 22 detects that the ON state continues for a certain period of time or more, the properly inserted coins push aside the sorting lever 20 and move into the accumulation track 1C. The sending of the signal to the sorting electromagnet 19 to enable the robot to move forward is temporarily stopped.

For this reason, the number of accumulated coins after that is the coin income of “J”.
As long as the amount is not reduced by the amount of money, all the money is returned as overflow money by the sorting lever 20.

As described above, the detection coil (T, Ml, J), M, 2
) and the coin information detected by the detection coil 22 for coin pass overflow detection and determined by the coin sorting device 100 are sequentially accumulated in the coin accumulation track 1C 7''
The coins are sequentially stored in correspondence with the type and number of coins.

The operation of the storage electromagnet 26 is as follows.

In other words, when the user dials ``M〃C sender 1'', a loop is formed with station C via the control circuit, and the billing signal sent from the station is sent to the billing signal receiving circuit. receives the coin, its output signal is sent to the control circuit, and the control circuit sends out the storage (fi) signal to the storage electromagnet 6.The storage electromagnet 26 operates according to this storage signal to store the coin. The devices (25, 26, 27° 28, 29, 30) are fully activated and the first accumulated coin is stored.

Since the coin processing device is constructed as described above, one coin track 1 is formed on one substrate 3 by lifting the transmitter/receiver. The coin slot 2 is set to a width that allows coins of the maximum diameter that can be inserted, so the
Any usable sum 1 type coins having a diameter of tl can be inserted and fall along the coin sorting track 1B. During the transfer and fall on this coin sorting track 1B, each detection coil (T.

Ml, 0%M21 distinguishes the thickness, diameter, type, and authenticity of the coin by 44J, and if the coin is a valid coin, Q:i, and the sorting electromagnet 19 is energized f, so if the coin is a valid coin, it is sorted. The electromagnet 19 is not passed through, so that the undelivered genuine coins are removed from the coin sorting track 1B by the lever 20, fall through the window 4b, and are discharged to the coin return slot. The passed proper coins are transferred to the coin accumulation track 1C and stopped at the return stopper 11g which has entered the terminal position A1 of the coin accumulation track 1C, and coins of a plurality of types are accumulated in the coin accumulation track 1C in the order of insertion. Ru.

Passage to this coin accumulation track 1C is confirmed by the coil 22. In addition, when a plurality of coins are accumulated and the coins reach the position of this coil 22 and it is detected that the coins are present at the position of the coil 22, the coins inserted after that are determined to be invalid coins, and the sorting is done by the lever 20. Then, the coin sorting orbit 'lB, lniji is removed.

When the storage signal arrives, the storage electromagnet 26 is energized, and as described above, the horizontal portion 27a of the storage stopper 27 exits the coin storage track 1C, and the coins at the storage position A2 fall into the coin storage opening, and the coins at the subsequent position A3. The coin is temporarily stopped by its abdomen being pressed by the elastic suppressing member 28C.
When the electricity is turned off, the sheet advances to the storage position A2, and thereafter, each sheet is stored one by one each time a storage signal arrives.

Coins that can be stored are detected by the coil 31, and coin storage is confirmed. When the K money box is full, the coil ゛31
detected by.

As explained above, in the coin processing device of the present invention, the coin sorting device M- detects the thickness, diameter, material, etc. of the coin falling on the coin sorting track using the 11.L air bacteria. Appropriate, inappropriate, and type are determined, and the device removes inappropriate coins based on the judgment of the coin sorting device, and only the appropriate coins advance to the coin accumulation track. coins are accumulated, and when storing, the abdomen of the coin in the succeeding position is pressed against the board by the elastic suppressing member and temporarily stopped, and the coin is stored one by one, regardless of the displacement of the succeeding coin. Multiple types of coins with different thicknesses, diameters, and materials can be sorted, accumulated, and
A series of processes such as storage and return can be performed, which greatly simplifies the structure.
