DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a coin discriminating apparatus according to a first embodiment of the present invention will be described below with reference to FIGS.

A coin discriminating apparatus 11 according to the first embodiment
Is a detection unit that is attached to the coin transport path 12 that transports the coin C, and that detects a pattern formed on the outer peripheral surface (the outer peripheral surface in the radial direction) of the coin C transported on the coin transport path 12. And a discriminating unit (discriminating means) 15 for discriminating the coin C based on the detection result of the detecting unit 14. Here, the coin discriminating apparatus 11 has a predetermined diagonal crease (pattern) in which grooves 16 extending obliquely at a predetermined angle with respect to the axial direction are arranged at a predetermined equal pitch on the outer peripheral surface.
This predetermined oblique crease 1 of the regular coin on which 17 is formed
7 is mainly detected.

The coin transport path 12 sandwiches the coin C in the axial direction, that is, the thickness direction, with a belt (not shown) or the like.
Coin transporting means (not shown) for transporting the coin while preventing its rotation
The coin C is inserted in a predetermined radial direction (FIG. 1).
(In the left-right direction in FIG. 1).

As the detection unit 14, a bar is formed by printing a long bar in one direction to form a bar, and a plurality of such bars are arranged in parallel in parallel with different widths and arrangement pitches. A bar code detection sensor for detecting a code is used.

Specifically, the bar code detecting sensor constituting the detecting section 14 has a light source 21 disposed on one side and a light receiving sensor 22 disposed on the other side via a light shielding plate 20. A cylindrical lens 23 is arranged on the light emitting direction side. The light source 21
For example, an LED is used, and as the light receiving sensor 22, for example, a phototransistor is used.

The bar code detecting sensor constituting the detecting unit 14 has a light source 21, a light shielding plate 20, and a light receiving sensor 22 arranged in a straight line, as shown in FIG.
The shape of the spot light 24 emitted from the light source 21 via the cylindrical lens 23 has a long bar shape parallel to the arrangement direction of the light source 21, the light shielding plate 20, and the light receiving sensor 22.

The bar code detecting sensor constituting the detecting section 14 includes a light source 21, a light shielding plate 20, and a light receiving sensor 2
In the state where the arrangement direction of the two, that is, the extending direction of the spot light 24 is parallel to the extending direction (length direction) of the bar of the bar code, the spot light is transmitted from the light source 21 through the cylindrical lens 23 to the bar code. The light is reflected by the light receiving sensor 22 via the cylindrical lens 23 while the light is reflected parallel to the bar. That is,
A posture in which the arrangement direction of the light source 21, the light shielding plate 20, and the light receiving sensor 22 is parallel to the extending direction of the barcode bar is a posture that can optimally detect the barcode bar.

A detecting section 14 comprising such a bar code detecting sensor is provided on the side of the coin transport path 12. At this time, the detecting unit 14 is configured to optimally detect the bar of the bar code (posture in the extending direction of the bar).
Is applied to a predetermined diagonal indentation 17 (extending direction of the groove 16) of regular coins conveyed in the coin conveyance path 12. That is, the arrangement direction of the light source 21, the light-shielding plate 20, and the light-receiving sensor 22 is inclined with respect to the axial direction of the coin C, and is parallel to the extending direction of the groove 16 of the predetermined oblique crease 17.

Further, as shown in FIG. 3, the detecting unit 14 sets the irradiation range Z1 of light in the axial direction of the coin C conveyed on the coin conveyance path 12 to the coin C on the coin conveyance path 12 and the coin C. The one end side (lower end side) of the coins is made to overlap, while the sensitivity range Z2 of the light receiving sensor 22 in the axial direction of the coin C conveyed in the coin conveyance path 12 is
One end (upper end) of the coin C is made to overlap the upper coin C, and the irradiation range Z1 and the sensitivity range Z2 are set.
Are overlapped only in the range of the coin C. This maximum sensitivity portion is, for example, always the cylindrical lens 23
Placed on the center of the

The discriminating unit 15 is a light receiving sensor 2 of the detecting unit 14.
The presence or absence of a predetermined diagonal crevice 17 is determined based on a light receiving signal that generates an output value corresponding to the amount of received light output from the light emitting device 2.

That is, when the light source 21 irradiates light toward the outer peripheral surface of the coin C conveyed on the coin conveying path 12, when the coin C has a predetermined diagonal ridge 17, the light source 21 outputs the cylindrical lens. The spot light 24 applied to the outer peripheral surface of the coin C via 23 coincides with the extending direction of the groove 16 of the oblique crease 17. Then, as shown in FIG. 4A, the output value of the light receiving signal of the light receiving sensor 22 increases, a plurality of peak values are generated, and the generation cycle of the peak value is shortened. And the discriminating unit 1
5 is a predetermined diagonal crease 1 based on such a light receiving signal.
7 is determined.

The discriminator 15, for example, detects that the output value of the received light signal has exceeded a predetermined threshold value a plurality of times within a predetermined time range, and that the detected coin C
In the meantime, while it is determined that the predetermined diagonal ridge 17 is formed, it is determined that the detected coin C is not formed with the predetermined diagonal ridge 17 in other states.

Here, the coin C is not formed with the predetermined diagonal ridges 17, but is formed with vertical ridges (patterns) in which grooves extending parallel to the axial direction are arranged at equal pitches on the outer peripheral surface. In this case, the spot light 2 radiated from the light source 21 to the outer peripheral surface of the coin C through the cylindrical lens 23
4 is inclined with respect to the extending direction of the groove of the vertical groove. Therefore, the light receiving signal of the light receiving sensor 22 is as shown in FIG.
As shown in (1), a plurality of peak values are generated, and the generation cycle of the peak values is shortened. However, the output value does not decrease and does not exceed a predetermined threshold value.

In addition, when the coin C has a diagonal ridge (pattern) formed at an angle different from the predetermined diagonal ridge 17, the spot light emitted from the light source 21 of the detection unit 14 to the outer peripheral surface of the coin C is formed. 24 will be inclined with respect to the extending direction of the oblique groove. Therefore, as shown in FIG. 4 (b), the light receiving signal of the light receiving sensor 22 has a plurality of peak values, and the generation cycle of the peak values is short. Never exceed.

Therefore, in the discriminating section 15, for example, the above threshold value is set as a first threshold value and a second threshold value smaller than the first threshold value is set. When a state that is lower than the threshold value of 1 and exceeds the second threshold value occurs a predetermined number of times within a predetermined time range, the coin C has an angle different from that of the vertical knurl or the predetermined oblique knurl 17. It may be determined that an oblique crease is formed.

If the coin C does not have the predetermined diagonal indentation 17 and has a stamp (pattern) formed on the outer peripheral surface, the light receiving sensor 22 detects the reflected light from the coin. As shown in (c), although the output value becomes large, the peak value generation period becomes long. Therefore, even if there is a state exceeding a predetermined threshold value, this state remains within a predetermined time range within a predetermined time range. Does not occur more than once.

Therefore, in the discriminating section 15, for example, even if the output value of the light receiving signal generated for the coin C exceeds the above-mentioned threshold value (first threshold value), it is determined that the output value is within the predetermined time range. If the coin C does not occur a predetermined number of times, it may be determined that a stamp is formed on the coin C.

In addition, when the coin C has no knurls or stamps, that is, in the case of a plain pattern, the light receiving signal of the light receiving sensor 22 has a small fluctuation and a predetermined threshold value (second threshold value). ).

Therefore, in the discriminating section 15, for example, if the output value of the light receiving signal for the coin C is lower than the second threshold value for a predetermined time, the coin C is provided with a knurl and a stamp. It may be determined that none is formed.

According to the coin discriminating apparatus of the first embodiment described above, since a bar code detecting sensor is used as the detecting unit 14, a general-purpose bar code detecting sensor can be used. Cost can be reduced. Therefore, cost reduction can be achieved.

Further, since the detecting section 14 is arranged in a state of being inclined with respect to the axial direction of the coin C, when a predetermined inclined jaw 17 is formed on the outer peripheral surface of the coin C, the predetermined inclined jaw 17 is formed. The detection posture can be adjusted to the inclination direction of the 17 (specifically, the posture of the detection unit 14 that can optimally detect the bar of the bar code with respect to the extension direction of the bar is changed to the extension direction of the groove 16. It is possible to reliably detect the predetermined diagonal ridge 17.

As described above, when a stamp is formed on the outer peripheral surface of the coin C, this stamp can also be detected, and a vertical or predetermined diagonal notch 17 is formed on the outer peripheral surface of the coin C. Can be detected when diagonal knurls having different angles are formed, and can be detected when neither a stamp nor a knurl is formed on the outer peripheral surface of the coin C.

Next, a coin discriminating apparatus according to a second embodiment of the present invention will be described below mainly with reference to FIG. 5, focusing on differences from the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 5, the coin discriminating device 25 according to the second embodiment also includes a coin conveying path 1 for conveying coins C.
2 and an outer peripheral surface (radial outer surface in the radial direction) of the coin C conveyed on the coin conveying path 12 in addition to the detecting section (first detecting means) 14 of the first embodiment. Detecting section (second detecting means) for detecting a pattern formed on the surface 26
Is provided. The detection unit 26 has the same configuration as the detection unit 14 and is a barcode detection sensor.

Here, this coin discriminating device 25 detects the presence or absence of the above-mentioned oblique jaw 17, and has a vertical jaw (pattern) in which grooves 27 extending parallel to the axial direction are arranged at a predetermined equal pitch. The presence / absence of the vertical indentation 28 of the coin C on which the coin 28 is formed is also detected.

The detection section 14 and the detection section 26 are provided side by side on the upstream and downstream sides of the coin transport path 12, but if they do not affect each other, the coin transport path 12
At the same position in the coin transport direction via the coin transport path 12.

The detecting section 26 also includes a light source 21, a light shielding plate 20, and a light receiving sensor 22 which are linearly arranged.
The shape of the spot light 24 radiated from the lens through the cylindrical lens 23 has a long bar shape parallel to the arrangement direction of the light source 21, the light shielding plate 20, and the light receiving sensor 22.

The detecting section 26 is also connected to the coin transport path 12.
Is provided on the side. At this time, the detecting unit 26 adjusts the attitude (the attitude with respect to the extending direction of the bar) of the bar C of the bar code to the direction of the vertical indentation 28 of the coin C conveyed in the coin conveying path 12 (the extension of the groove 27). Direction). That is, the orientation in which the arrangement direction of the light source 21, the light shielding plate 20, and the light receiving sensor 22 is parallel to the axial direction of the coin C, in other words, the orientation in which the extending direction of the groove 27 of the vertical indentation 28 of the coin C is parallel. And

As shown in FIG. 3, the detecting unit 26 also applies the light irradiation range Z1 in the axial direction of the coin C conveyed on the coin conveying path 12 to the coin C on the coin conveying path 12. While one end side (lower end side) of the coin C is overlapped, the sensitivity range Z2 of the light receiving sensor 22 in the axial direction of the coin C conveyed on the coin conveyance path 12 is shifted to the coin C on the coin conveyance path 12. One end (upper end) of the coin C is made to overlap, and the irradiation range Z1 and the sensitivity range Z2 are overlapped only in the range of the coin C. This maximum sensitivity portion is always arranged on the center of the cylindrical lens 23.

The discriminating unit 30 includes the light receiving sensor 2 of the detecting unit 14.
2 and a light receiving signal that generates an output value corresponding to the amount of received light output from the light receiving sensor 22 of the detection unit 26 based on a received light signal that generates an output value corresponding to the amount of received light output from
The presence / absence of the diagonal ridge 17 and the presence of the vertical ridge 28 of the coin C are mainly detected.

That is, when the light source 21 of the detection unit 14 irradiates light toward the outer peripheral surface of the coin C conveyed on the coin conveyance path 12, when the coin C The spot light 24 emitted from the light source 21 of the detection unit 14 to the outer peripheral surface of the coin C via the cylindrical lens 23 coincides with the extending direction of the groove 16 of the oblique jaw 17. Then, as shown in FIG. 4A, the light receiving signal of the light receiving sensor 22 of the detecting unit 14 has an increased output value, generates a plurality of peak values, and shortens the generation period of the peak value.

When the coin C is formed with a predetermined diagonal indentation 17, the other detecting unit 26 emits the spot light 24 radiated from the light source 21 to the outer peripheral surface of the coin C through the cylindrical lens 23. 17 is inclined with respect to the extending direction of the groove 16. Therefore, the light receiving signal of the light receiving sensor 22 for the coin C is, as shown in FIG.
Although a plurality of peak values are generated and the generation cycle of the peak values is shortened, the output value is smaller than the above.

Therefore, the discriminating unit 30 determines that, for example, a state in which the output value of the light receiving signal from the detecting unit 14 for the coin C increases and exceeds the predetermined first threshold value within a predetermined time range A state in which the output value of the received light signal from the detection unit 26 for the same coin C occurs a plurality of times and exceeds the second threshold value that is lower than the first threshold value and smaller than the first threshold value. When a predetermined number of occurrences occur in the coin C within the time range, it is determined that the coin C has a predetermined oblique indentation 17 formed thereon.

In the case where the coin C has the vertical knurls 28 formed thereon, the spot light 24 emitted from the light source 21 of the detection unit 26 to the outer peripheral surface of the coin C coincides with the extending direction of the groove 27 of the vertical knurls 28. Will be. Then, as shown in FIG. 4A, the light receiving signal of the light receiving sensor 22 of the detecting unit 26 has a larger output value and a plurality of peak values, as shown in FIG.
Moreover, the peak value generation cycle is shortened.

On the other hand, the detecting unit 14 applies a vertical
8 is formed, the spot light 24 emitted from the light source 21 to the outer peripheral surface of the coin C is
7 will be inclined with respect to the extending direction of 7. Therefore, the light receiving signal of the light receiving sensor 22 of the detecting unit 14 for the coin C is
As shown in FIG. 4B, a plurality of peak values are generated, and the generation cycle of the peak values is shortened, but the output value does not become small and does not exceed a predetermined threshold value.

Accordingly, the discriminating unit 30 determines that the state in which the output value of the light receiving signal from the detecting unit 26 for the coin C increases and exceeds the predetermined first threshold value within a predetermined time range A state that occurs a plurality of times and the output value of the received light signal from the detection unit 14 for the same coin C exceeds a second threshold smaller than the first threshold and smaller than the first threshold is a predetermined state. If the coin C is generated a plurality of times within the time range, it is determined that the coin C has the vertical indentation 28 formed thereon.

Here, when the coin C has a diagonal ridge (pattern) formed at an angle different from the predetermined diagonal ridge 17, the spot light emitted from the light source 21 of the detection unit 14 to the outer peripheral surface of the coin C is formed. 24 is inclined with respect to the extending direction of the oblique groove, and the spot light 24 emitted from the light source 21 of the detecting unit 26 to the outer peripheral surface of the coin C is also inclined with respect to the extending direction of the oblique groove. Become. Therefore, the light receiving signal of the light receiving sensor 22 of the detecting unit 14 and the light receiving signal of the light receiving sensor 22 of the detecting unit 26 with respect to the coin C are as shown in FIG.
As shown in (b), a plurality of peak values are generated, and the generation cycle of the peak values is shortened, but the output value becomes small and exceeds a predetermined threshold value (second threshold value). Absent.

Therefore, in the discriminating unit 30, for example, both output values of the light receiving signal of the detecting unit 14 and the light receiving signal of the detecting unit 26 for the coin C are both lower than the first threshold value and the first threshold value. When a condition exceeding the smaller second threshold occurs a predetermined number of times within a predetermined time range,
The coin C may be determined to have a diagonal ridge different from the predetermined diagonal ridge 17.

When a mark (pattern) is formed on the outer peripheral surface of the coin C, when the light receiving sensor 22 of the detecting section 14 and the light receiving sensor 22 of the detecting section 26 detect reflected light from the same coin C, In either case, as shown in FIG. 4C, the output value increases, but the peak value generation cycle becomes longer. It does not occur a predetermined number of times within the time range.

Therefore, in the discriminating section 15, even if both output values of the light receiving signal of the detecting section 14 and the light receiving signal of the detecting section 26 exceed the above-mentioned threshold value, for example, it is determined that this value is within a predetermined time range. If a predetermined coin is not generated a plurality of times, it may be determined that a stamp is formed on the detected coin.

In addition, in the case of a plain pattern in which no coins and inscriptions are formed on the coin C, the light reception signal of the detection unit 14 and the light reception signal of the detection unit 26 both have small fluctuations in output value, and The threshold of 2 is not exceeded.

Therefore, the discriminating unit 30 detects, for example, when both output values of the light receiving signal of the detecting unit 14 and the light receiving signal of the detecting unit 26 remain below the second threshold for a predetermined time. The coin C may be determined not to have any knurls or stamps.

According to the coin discriminating apparatus 11 of the second embodiment described above, since the bar code detecting sensor is also used for the detecting unit 26, a general-purpose bar code detecting sensor is used. Cost can be reduced. Therefore, cost reduction can be achieved.

Further, when the detecting section 14 has a predetermined diagonal ridge 17 formed on the outer peripheral surface of the coin C, the detection posture can be adjusted to the tilt direction of the diagonal ridge 17 (specifically, The posture of the detection unit 14 that can optimally detect the bar of the bar code in the direction in which the bar extends can be applied to the direction in which the groove 16 of the predetermined diagonal 17 extends. 17 can be reliably detected.

Further, when the detecting portion 26 has a vertical jaw 28 formed on the outer peripheral surface of the coin C, the vertical jaw 28
Can be adjusted to the direction (specifically,
The attitude of the detection unit 26, which can optimally detect the bar of the bar code, with respect to the direction in which the bar extends can be applied to the direction in which the groove 27 of the vertical groove 28 extends). Can be detected.

By combining the detection results of the detection unit 14 and the detection unit 26, if the stamp is formed on the outer peripheral surface of the coin C as described above, this stamp can also be reliably detected. If the coin C is formed with a diagonal ridge different from the predetermined diagonal ridge 17 on the outer peripheral surface of the coin C,
This can also be reliably detected, and the coin C
If neither the engraved mark nor the knurl is formed on the outer peripheral surface of, this can also be reliably detected.
