Description of the Related Art As a coin discriminating / counting device for discriminating whether or not a coin inserted into a coin processor is a denomination or a circulating coin, there is one disclosed in Japanese Patent Laid-Open No. 3-73091. This coin discriminating and counting device has a plurality of light-emitting elements that irradiate the coins conveyed in the conveying passage in a state where they are separated one by one, and a coin that is conveyed to the opposite side of the light-emitting element. A line sensor is provided, which detects the diameter of the coin, and determines the denomination from the size of the detected diameter. in addition,
A magnetic sensor for detecting the magnetic properties of coins is provided in the vicinity of the line sensor, and the magnetic data of coins detected by this magnetic sensor and the reference magnetic data of coins of denomination obtained from the detection result of the line sensor are provided.

[0003]

The coin discriminating and counting device as described above is required for a coin processing machine which mainly deposits, counts, and packages coins. However, such a coin processing machine is used. Most coins are generally circulated, and even if they are true coins, they often include coins whose shape is deformed. When such a deformed coin is thrown into a coin processing machine or the like and the coin discriminating / counting device described above determines whether or not the denomination or the circulating coin, it is detected whether or not the coin is deformed. Therefore, there is a possibility that the coins will be conveyed as normal coins to other mechanical parts as they are, and if such deformed coins are processed together with normal coins in other mechanical parts, the deformed coins will be deformed. May cause a jam, or may cause a malfunction such as a malfunction of another mechanism or damage to the mechanism. Further, in a so-called circulation type coin depositing / dispensing machine that reuses deposited coins for dispensing, if a deformed coin is dispensed, it may cause discomfort to a customer who receives the deformed coin. There is also the problem of becoming. Therefore, an object of the present invention is to provide a deformed coin detection device that can reliably detect a deformed coin that causes a problem such as a jam when performing various processes on a coin.

[0004]

In order to achieve the above object, the invention according to claim 1 is such that a conveying means for linearly moving a coin on a conveying surface at a constant speed and a plurality of detecting elements capable of detecting coins are straight lines. Of the line sensor and the detection element of the line sensor, the line sensor being arranged orthogonally to the coin conveying direction so as to face either one of the upper and lower surfaces of the coin moving on the conveying surface. The coin is detected while detecting the width of the coin in the direction along the carrying direction from the detection time of the coin by any one of the detecting elements that first detects the moving coin and the carrying speed by the carrying means. A detection unit that detects the width of the coin in the direction orthogonal to the conveying direction from the distance between the farthest detection elements, and determines whether or not the coin is a deformed coin based on these widths. It is characterized in that. Therefore,
The determining means determines the width in the direction along the carrying direction of the coin from the detection time of the coin by any one of the detecting elements that first detects the moving coin among the detecting elements of the line sensor and the carrying speed by the carrying means. Along with detecting, the width of the coin in the direction orthogonal to the conveying direction is detected from the distance between the furthest ones of the detecting elements that have detected the coin, and if the coin is normal, the difference should be within the allowable error range. Whether or not the coin is a deformed coin is determined from the width.

According to a second aspect of the present invention, a large number of detecting elements capable of detecting coins on the conveying surface are arranged in a plane, and the detecting elements face one of the upper and lower surfaces of the coin on the conveying surface. It is characterized by comprising an arranged area sensor and a judgment means for judging whether or not the coin is a deformed coin based on pattern data of the coin detected by a detection element of the area sensor. Therefore, the determination means determines whether or not the coin is a deformed coin from the pattern data of the coin detected by the detection element of the area sensor.

According to a third aspect of the present invention, a conveying means for linearly moving the coin on the conveying surface at a constant speed and a plurality of detecting elements capable of detecting the coin are arranged in a straight line, and the conveying surface is arranged on the conveying surface. A line sensor that is arranged orthogonal to the transport direction of the coin so as to face one of the upper and lower surfaces of the moving coin, and a line that connects the two sides in the radial direction of the coin that moves on the transport surface. A photo sensor composed of a light emitting element and a light receiving element which are arranged so as to be orthogonal to the coin carrying direction, a detection time for detecting a moving coin with the photo sensor, and a carrying speed by the carrying means in the carrying direction of the coin. The width in the direction along the coin is detected, and the width in the direction orthogonal to the transport direction of the coin is detected from the distance between the furthest ones of the detection elements of the line sensor that has detected the coin. It is characterized by comprising determination means for determining whether the coin is a deformed coin, from width. Therefore, the determination means detects the width in the direction along the transport direction of the coin from the detection time for detecting the moving coin with the photosensor and the transport speed by the transport means, and the detection element of the line sensor that has detected the coin. Detecting the width of the coin in the direction orthogonal to the conveying direction from the distance between the most distant ones, if the coin is a normal coin, the difference should be within the allowable error range. Will be determined. Moreover, since the line connecting the light-emitting element and the light-receiving element of the photo sensor is along the transport surface of the coin, the determination means detects that the coin does not come into contact with the transport surface due to deformation. The width of the coin in the conveying direction, which is obtained from the time, is shorter than the allowable error with respect to the width in the direction orthogonal to the coin detecting direction detected by the line sensor, or approximately the width in the direction orthogonal to the conveying direction. Even when the coin is deformed such as being slightly warped to the extent that it is difficult to detect an abnormality in the diameter due to short interruptions in the same distance, the deformation can be detected.

According to a fourth aspect of the present invention, in addition to the third aspect, the determination means further includes any one of the detection elements of the line sensor that first detects the moving coin. Also from the detection time of the coin and the detection time of detecting the coin with the photo sensor,
It is characterized by determining whether or not the coin is a deformed coin. Therefore, the determination means, if the difference is normal coins, the difference should be within the allowable error range, the detection time of the coin by any one of the detection elements that first detects the moving coin among the detection elements of the line sensor, and Whether or not the coin is a deformed coin can also be determined from the detection time for detecting the coin with the photo sensor.

According to a fifth aspect of the present invention, a conveying means for linearly moving a coin on the conveying surface at a constant speed and a pair of conveying means are arranged on both sides in the radial direction of the coin moving on the conveying surface. Two pairs of photosensors, which are composed of a light emitting element and a light receiving element, and are arranged so that the lines connecting the light emitting element and the light receiving element are symmetrically inclined at the same angle with respect to the coin transport direction, and a moving coin. And a determination unit that determines whether or not the coin is a deformed coin, based on the detection time of each photosensor. Therefore, the determination means
If the coin is a normal coin, it is determined whether or not the coin is a deformed coin based on the detection time of each moving photocoin that the difference should fall within the allowable error range. Moreover, since the line connecting the light-emitting element and the light-receiving element of each photosensor is along the transportation surface of the coin, the determining means uses the fact that the deformation causes a portion where the coin does not contact the transportation surface. The time when the optical path of each photosensor is cut off, that is, the non-light receiving time is shorter than the possible time for coins of all denominations by more than a permissible error, or intermittently shorter during the time, and further,
The time when the optical path of one of the photosensors is blocked, that is, the non-light receiving time, is shorter than the allowable error with respect to the time when the optical path of the other photosensor is blocked, that is, the non-light receiving time, or during that time. It is determined that the coin is a deformed coin by detecting that the coin is intermittently short.

According to a sixth aspect of the present invention, in addition to the first aspect, each comprises a pair of light emitting element and light receiving element which are arranged on both sides in a radial direction of the coin moving on the carrying surface. , Further comprising two pairs of photosensors provided so that the lines connecting the respective light emitting elements and light receiving elements are symmetrically inclined at the same angle with respect to the coin transport direction, and the determination means is further moved. It is also characterized in that whether or not the coin is a deformed coin is determined from the detection time of each coin in each photo sensor. Therefore, the determination means also determines whether or not the coin is a deformed coin from the detection time of each moving photocoin in each photosensor.

According to a seventh aspect of the present invention, with respect to the second aspect of the present invention, a conveying means for linearly moving the coin on the conveying surface at a constant speed, and a coin in the radial direction of each coin moving on the conveying surface. Two pairs consisting of a pair of light emitting element and light receiving element arranged on both sides, and a line connecting the light emitting element and the light receiving element is symmetrically inclined at the same angle with respect to the coin transport direction. Is further provided, and the determination means further determines whether or not the coin is a deformed coin, from the detection time of each moving photocoin in each photosensor. Therefore, the determination means also determines whether or not the coin is a deformed coin from the detection time of each moving photocoin in each photosensor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A modified coin detecting device according to a first embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 11 indicates a horizontally extending transport surface 11.
A coin passage having a shape extending linearly with a is denoted by reference numeral 1
2 and 13 have mutually opposing surfaces 12a and 13a which are perpendicular to the transport surface 11a and are parallel to the both side edges of the transport surface 11a of the coin passage 11 apart from the outer diameter of the coin having the maximum outer diameter of the coin C to be handled. A pair of linear guide portions provided in the form of a reference numeral 14 conveys coins C on the conveying surface 11a between the guide portions 12 and 13 in a straight line at a constant speed along the extending direction of the coin passage 11. Means are shown respectively.

Here, although not shown, a separating and feeding means for separating and feeding the coins C one by one is provided on one side in the extending direction of the coin passage 11, and on the other side, for example, Appropriate coin processing means for accumulating a predetermined number of the coins C for packaging and the like is provided, and the conveying means 14 receives the coins C fed out from the separating and feeding means and conveys the coins C to be fed out to the coin processing means. ing.

The conveying means 14 includes two pairs of pulleys 16 arranged above the conveying surface 11a between the guide portions 12 and 13 and along the extending direction of the conveying surface 11a, and each pair of pulleys 16 respectively. It has two belts 17 made of an elastic material such as a stretched rubber and a drive unit for rotating both belts 17 at a constant speed.

Here, in each of the belts 17, the lower linear portion between the pulleys 16 has guide portions 12, 13 on the conveying surface 11a.
The position in the horizontal direction is aligned with the central position of the space (that is, along the extending direction of the transport surface 11a) and the transport surface 11a
The coins C to be dealt with are arranged parallel to each other with a distance slightly smaller than the thickness of the coins with the smallest thickness,
Are arranged in series with each other along the extending direction. As a result, when driven by the drive unit at a constant speed, both belts 17 transfer the coin C on the transport surface 11a to the transport surface 11a.
And the coin C is held integrally by the frictional force generated by the sandwiching, and the coin C is linearly moved along the extending direction on the conveying surface 11a. Further, the belts 17 are separated from each other within a range in which the coins C having the smallest outer diameter can be simultaneously held by the belts 17.

Then, in the coin passage 11, the guide portion 12, with the horizontal position aligned with the separated portion of the belt 17,
A transparent plate 19 is fitted between 13 so as to extend slightly beyond these, and the transparent plate 19 has the upper surfaces thereof aligned with each other to form the transport surface 11a of the coin passage 11 in the same manner. A line sensor 20 is provided below the transparent plate 19 so as to face the lower surface of the coin C that moves on the upper surface of the transparent plate 19 that constitutes the transport surface 11a. The line sensor 20 aligns the position in the horizontal direction on the lower side of the transparent plate 19 with the separated portion of the belt 17, and at the same time as the conveyance surface 1.
A large number of light receiving elements (detection elements) 20 arranged in a straight line in a horizontal direction orthogonal to the extending direction of 1a at a predetermined interval.
a.

At the upper position between the belts 17, a large number of light emitting elements (not shown) are arranged in alignment with the light receiving elements 20a in the horizontal direction. Accordingly, when the coin C moving on the transport surface 11a is positioned above the light receiving element 20a of the line sensor 20, the light receiving element 20a stops the light emitted from the light emitting element and stops receiving light (hereinafter, referred to as "light receiving element 20a"). The state in which the light receiving element does not receive the light emitted from the light emitting element is referred to as a non-light receiving state), and the coin C is detected, and the light emitted from the light emitting element is received without being blocked (hereinafter, referred to as "non-light receiving state"). The state in which the light receiving element receives the light emitted from the light emitting element is referred to as a light receiving state), and the coin C is not detected.

In the line sensor 20, detection is started from a state where all the light receiving elements 20a are in the light receiving state, and one of the light receiving elements 20a is in the non-light receiving state, and then all the light receiving elements 20a are re-detected. From the maximum value of the distance (predetermined) between the most distant light-receiving elements 20a that have been in the non-light-receiving state at the same time until the light-receiving state is reached, the width D _{1 of the} detected coin C in the direction orthogonal to the transport direction The width direction detecting means 22 for detecting the conveyance orthogonal direction is connected as shown in FIG.

Here, various coins Ca to Cd shown in FIGS. 4A to 4D (FIG. 4A is a normal coin Ca, FIG.
In the case of various deformed coins Cb to Cd, (b) to (d) show that any one of the light receiving elements 20a becomes a non-light receiving state as shown in each middle row, and then all the light receiving elements 20a are set to the light receiving state again. In the time until it becomes
The relationship between the distances of 0a is changed as shown in the lower tier with time on the X-axis and the distance on the Y-axis. From the maximum value of the distance in the lower tier, the distance D ₁
Is extracted.

Further, in the line sensor 20, detection is started from a state in which all the light receiving elements 20a are in a light receiving state, and when any one of the light receiving elements 20a is in a non-light receiving state, the line sensor 20 is initially in a non-light receiving state. The detection time measuring means 23 for measuring the time until the light receiving element 20a which has become a light receiving state, that is, the detection time T ₁ of the coin C is connected. Since there is a coin C of a denomination having a hole in the center in Japan, even if the light receiving element 20a that was initially in the non-light receiving state is in the light receiving state in order to ignore this hole, If any of the other light receiving elements 20a is in the non-light receiving state at the time point, the light receiving state of the light receiving element 20a which is initially in the non-light receiving state is ignored and the non-light receiving state is maintained and the detection time is maintained. It is designed to continue the measurement of.

The detection time measuring means 23 multiplies the detection time T ₁ of the coin C measured by the detection time measuring means 23 by the predetermined conveying speed S of the conveying means 14 to calculate the conveying direction of the coin C. Conveyance direction width detecting means 24 for detecting the width D ₂ in the direction along is connected. Conveyance direction width detection means 2
4 and the conveyance orthogonal direction width detection means 22 are connected to a main determination means 25 for determining whether or not the detected coin C is a deformed coin based on the width D ₁ and the width D ₂ detected by these. ing. The main determination means 25 uses D ₁ = D ₂ ± Δd (Δd
Is satisfied, it is determined that the detected coin C is a normal coin, that is, it is not a deformed coin, and if the above formula is not satisfied, it is determined that the detected coin C is a deformed coin.

In the first embodiment, the conveyance orthogonal direction width detecting means 22, the detection time measuring means 23, the conveyance direction width detecting means 24 and the main judging means 25 are arranged in a direction along the coin C conveying direction. The determination unit 26 that detects the width and the width in the direction orthogonal to the conveying direction and that determines whether or not the coin C is a deformed coin is configured based on these widths. The determining unit 26 and the conveying unit 14 The line sensor 20 and the light emitting element (not shown) constitute a deformed coin detecting device.

According to the first embodiment configured as described above, the coins C are transferred one by one by the transfer means 14 to the transfer surface 11.
The line sensor 20 passes through the line sensor 20 by being moved straight along a at a predetermined constant speed. At this time,
With respect to the coin C that has passed, the determination unit 26 causes the detection time measuring unit 23 to detect the light receiving element 2 of the line sensor 20.
0a, the detection time of the coin C by any one of the light receiving elements 20a that first detects the coin C is measured,
The width in the direction along the carrying direction of the coin C is detected by the carrying direction width detecting means 24 from the detection time and the carrying speed of the carrying means 14, and the coin C is detected by the carrying orthogonal direction width detecting means 22. The width of the coin C in the direction orthogonal to the conveying direction is detected from the distance between the most distant light receiving elements 20a, and the main determination means 25 determines that the difference should be within the allowable error range if the coin is normal. From the width, it is determined whether or not the coin C is a deformed coin. In this way, the deformed coin can be reliably detected by determining whether or not the detected coin C is the deformed coin based on the partial width abnormality caused by the deformation.

When it is necessary to determine whether or not a coin is a denomination or a circulating coin, it is necessary to detect the diameter for the determination because of the processing of an appropriate coin processing means on the downstream side. Since the line sensor 20 can be shared, it is possible to prevent an increase in the number of parts. Also,
A light emitting element may be provided on the same side as the line sensor 20, and the light emitting element may illuminate the lower surface side of the coin C so that the light reflected by the coin C is received by the light receiving element 20a (in this case, light reception). In the element 20a, the light receiving state is the state in which the coin C is detected, and the non-light receiving state is the state in which the coin C is not detected.) In this way, it is not necessary to divide the belt 17 of the conveying means 14 as described above.

Next, a modified coin detecting device according to a second embodiment of the present invention will be described below with reference to FIGS. 5 to 8 focusing on the difference from the first embodiment. In addition,
The same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. In the second embodiment, the transport means 1
Reference numeral 4 denotes a pair of pulleys (not shown) instead of two pairs as in the first embodiment, and a belt 17 that is hung on these pulleys.
And a drive unit that rotates the belt 17 at a constant speed, and the coin passage 11 is not provided with a line sensor.

In the coin passage 11, a transparent plate 30 having a length in the extending direction larger than the outer diameter of the coin C having the maximum outer diameter to be handled is fitted between the guide portions 12 and 13. The transparent plate 30 constitutes the conveying surface 11a of the coin passage 11 by matching the upper surfaces thereof. An area sensor 32 is provided on the lower side of the transparent plate 30 so as to face the lower surface of the coin C moving on the upper surface which is the transport surface 11a of the transparent plate 30 with the condenser lens 31 interposed therebetween. Has been. This area sensor 32
Is a light receiving element (detection element) (not shown) horizontally arranged in a planar shape (lattice shape) at predetermined intervals below the transparent plate 30.
have.

A coin C located on the transparent plate 30 is below the transparent plate 30 and above the condenser lens 31.
A large number of light emitting elements 33 that irradiate light from obliquely below are provided on the lower surface side of the. As a result, when the coin C moving on the transport surface 11a is positioned inside the transparent plate 30 as a whole,
The light emitted from the light emitting element 33 and reflected by the coin C is condensed by the condenser lens 31 and then received by the light receiving element of the area sensor 32.

A timing sensor 34, which is composed of a pair of light emitting elements 34a and light receiving elements 34b, is provided at a position downstream of the transparent plate 30 in the direction in which the coin C is conveyed, with the transparent plate 30 sandwiched therebetween. Here, the arrangement position of the timing sensor 34 is blocked by the coin C moving on the transport surface 11a from the state where the light emitted by the light emitting element 34a is received by the light receiving element 34b, and the light receiving element 3
At the timing of not receiving light by 4b, the interrupted coin C is located inside the transparent plate 30 as a whole and is located at a position where the area sensor 32 can detect the entire reflected light. The coins of all denominations are set to be located at the position.

In the area sensor 32, the light receiving portion or the non-light receiving portion of the light receiving element of the area sensor 32 is developed into a coordinate system similar to the arrangement of the light receiving element, and the binary value of the shape of the detected coin C is detected. The pattern data binarizing means 36 for creating the converted pattern data is connected as shown in FIG. Specifically, the pattern data binarization means 36
Is developed into XY coordinates in which the direction along the carrying direction of the coin C is the X axis and the direction orthogonal to this is the Y axis to create binarized pattern data as shown in the middle part of FIG. 8 (FIG. 8). In the middle row, only the boundary part of the binary is shown by a solid line,
For reference, a true circle having the maximum value in the Y-axis direction as the outer diameter is shown by a dashed line. When the timing sensor 34 outputs a signal at the above timing, the area sensor 32 converts the data at that time into the pattern data binarizing means 3.
6 is output.

The pattern data binarizing means 36 includes
The created binarized pattern data is converted to the X axis, that is, Y =
Converted to the XY coordinate system with 0 as a reference (the coordinate value of the X axis remains the same and the one with the smaller coordinate value of the Y axis matches Y = 0), and the converted data as shown by the solid line in the lower part of FIG. Is connected to the data conversion means 37. here,
The data conversion means 37 has a reference conversion data creation means 38.
Is connected, and the reference conversion data creating means 38 is connected.
8 is a lower part of FIG. 8 in which the maximum value in the Y-axis direction is calculated from the conversion data of the detected coin C output from the data conversion means 37 and similarly converted for the true circle having the maximum value in the Y-axis direction as the outer diameter. The conversion data indicated by the alternate long and short dash line is created as the reference conversion data.

The data converting means 37 and the reference conversion data creating means 38 transform the detected coin C from the conversion data of the detected coin C output from the data converting means 37 and the reference conversion data corresponding to the conversion data. A main judging means 39 for judging whether or not it is a coin is connected. The main determination means 39 has reference conversion data having the maximum value in the Y-axis direction of the conversion data of the detected coin C output from the data conversion means 37, which is created by the reference conversion data creation means 38, and data. The degree of coincidence between the converted data of the detected coin C output from the conversion means 37 and the maximum values in the Y-axis direction are matched with each other. When the degree of coincidence is equal to or more than a predetermined value, it is determined that the detected coin C is a normal coin, that is, not a deformed coin, and when the degree of coincidence is less than the predetermined value, the detected coin C is Judged as a deformed coin.

In the second embodiment, the pattern data binarizing means 36, the data converting means 37, the reference conversion data creating means 38 and the main judging means 39 are detected by the light receiving elements of the area sensor 32. A determination unit 40 that determines whether or not the coin C is a deformed coin from the pattern data of the coin C is configured, and the determination unit 40, the transport unit 14, the area sensor 32, the light emitting element 33, and the timing sensor 34 are provided. Constitutes a modified coin detecting device.

According to the second embodiment configured as described above, the coins C are transferred one by one by the transfer means 14 to the transfer surface 1.
Although it passes over the transparent plate 30 by being moved along 1a, the area sensor 3 is located at the timing on the transparent plate 30 and detected by the timing sensor 34.
The determination means 40 makes the pattern data detected by the two light receiving elements into the binarized pattern data by the pattern data binarizing means 36, and further converts it into the converted data by the data converting means 37, and the reference conversion. The data creating means 38 creates the reference conversion data in the case of a non-deformed perfect circle, and the main judging means 39 compares these conversion data with the reference conversion data, and the coin C is a deformed coin based on the degree of coincidence. It will be decided whether or not. In this way, it is possible to reliably detect a deformed coin by determining whether or not the coin is a deformed coin based on the abnormal shape caused by the deformation. Further, even when the contact area of the belt 17 with the coin C becomes small due to the deformation of the coin C or the like, the frictional force is insufficient and slippage occurs, and the coin cannot be conveyed at a constant speed. Can be detected.

In place of the standard conversion data creating means 38, conversion data for normal coins of each denomination are previously calculated.
It is also possible to employ a reference data storage unit that stores the reference conversion data. In this case, the main determination means 40
Is, for example, the detected coin C output from the data conversion means.
From the converted data, the maximum value in the Y-axis direction is calculated, reference data having the maximum value (outer diameter value) in the Y-axis direction that is closest to the maximum value is read from the reference data storage means, and these are read in the X-axis direction. In the state where the maximum values in the Y-axis direction are matched with each other and Y = 0 is matched in the Y-axis direction, the matching degree may be obtained. In addition, the timing sensor 34
Instead of the area sensor 32, with respect to the light receiving elements of a predetermined row which are located on the downstream side of the coin transport direction and orthogonal to the transport direction,
Data may be output from the area sensor 32 to the pattern data binarizing means 36 when any one of them receives light, that is, when the coin C is detected. Further, if necessary for the processing on the downstream side, the area sensor 3
It is also possible to determine the diameter of the coin C from the detection result of 2 and determine the denomination.

Next, a modified coin detecting device according to a third embodiment of the present invention will be described below with reference to FIGS. 9 to 12, 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 is omitted. In the third embodiment, on the downstream side of the line sensor 20 in the transport direction of the coin C, both guide portions 12, which are parallel to the transport surface 11a, are orthogonal to the transport direction of the coin C, and form the same straight line, Through holes 42, 43 penetrating through 13 are formed, and on the outside of these through holes 42, 43 on both sides in the radial direction of the coin C moving on the transport surface 11a, a line connecting them, that is, an optical path is formed. , Passing through the through-holes 42, 43 in parallel or coaxial with the axis thereof as close as possible to the transport surface 11a so as to detect the coin C transported on the transport surface 11a without interfering with the transport means 14. A photo sensor 45 including a pair of a light emitting element 45a and a light receiving element 45b is provided.

Then, the line sensor 20 has a width D ₁ in the direction orthogonal to the transport direction of the coin C from the maximum value of the distance (predetermined) between the farthest light receiving elements 20a which are in the non-light receiving state at the same time. Conveyance orthogonal direction width detection means 22 for detecting
Only are connected as shown in FIG.

On the other hand, the photo sensor 45 includes a light receiving element 4
The detection time measuring means 47 which starts detection from the state where 5b is in the light receiving state and measures the time from the non-light receiving state of the light receiving element 45b to the light receiving state again, that is, the detection time T ₂ of the coin C. Are connected. The detection time measuring means 47 multiplies the detection time T ₂ of the coin C measured by the detection time measuring means 47 and the predetermined conveying speed S of the conveying means 14 to obtain a direction along the conveying direction of the coin C. The width D ₃ in the transport direction for detecting the width D ₃ is connected.

The conveyance direction width detection means 48 and the conveyance orthogonal direction width detection means 22 determine whether or not the detected coin C is a deformed coin from the widths D ₁ and D ₃ detected by these means. The main judging means 49 is connected. The main determination means 49 determines that the detected coin C is a normal coin, that is, not a deformed coin when D ₁ = D ₃ ± Δd (Δd is an allowable error) is satisfied, and the above formula is not satisfied. In this case, it is determined that the detected coin C is a deformed coin.

In addition, the optical path of the photo sensor 45 is the transport surface 1
1a, the main determining means 49 utilizes the fact that the deformation causes a portion of the coin C that is not in contact with the transport surface 11a, so that the coin C is obtained from the time when the optical path is blocked, that is, the non-light-receiving time. Width D in the transport direction
₃ is shorter than the permissible error with respect to the width of the coin C which is already detected by the line sensor 20 on the upstream side in the direction orthogonal to the conveying direction, or is approximately the width in the direction orthogonal to the conveying direction. It is determined that the coin is a deformed coin by detecting that it is intermittently interrupted within the same distance.

Specifically, for a normal coin Ca, FIG.
As shown in (a), the detection level of the photo sensor 45 is L.
The time (the time in the non-light-receiving state) is maintained for a certain time, while the detection level is L in the case of the deformed coin Cd in which both ends in the transport direction are curved upward as shown in FIG. Is shorter than the predetermined time, resulting in a shorter width in the carrying direction.
Deformed coin C whose one end is bent downward as shown in FIG.
In the case of b, or in the case of a deformed coin Cc whose both ends are bent in opposite directions as shown in FIG. 12 (c), the time when the detection level becomes L is the width D ₃ in the direction orthogonal to the carrying direction.
There are short interruptions during the same time as moving around. Therefore, the main determination means 49 determines these abnormalities by detecting these abnormalities.

Here, since the line sensor 20 and the photo sensor 45 are arranged so as to be displaced in the transport direction of the coin C,
The main determination means 49 is composed of the line sensor 20 and the photo sensor 4.
5 is detected by the line sensor 20 and the photo sensor 45 at a timing with a time difference obtained by dividing the distance between the transfer unit 5 and the transfer speed of the coin C by the transfer unit 14 (in this case, the line sensor 20 detects First) It is determined that the coin C is the same coin C. Further, the photo sensor 45 is not limited to the downstream side of the line sensor 20 in the transport direction of the coin C, but can be of course provided on the upstream side.

In the third embodiment, the conveyance orthogonal direction width detecting means 22, the detection time measuring means 47, the conveyance direction width detecting means 48 and the main judging means 49 are arranged in the direction along the coin C conveying direction. The width and the width of the coin C in the direction orthogonal to the conveying direction are detected, and the determination unit 50 that determines whether or not the coin is a deformed coin is configured based on these widths.
The determining means 50, the conveying means 14, the line sensor 20, the light emitting element, and the photo sensor 45 constitute a deformed coin detecting device.

According to the third embodiment having the above construction, the coins C are transferred one by one by the transfer means 14 to the transfer surface 11.
By passing straight line at a constant speed along a, it passes through the line sensor 20, and then passes between the light emitting element 45a and the light receiving element 45b of the photo sensor 45. , Determination means 5
0 indicates the width of the coin C in the direction orthogonal to the conveying direction from the distance between the furthest light receiving elements 20a that detect the coin C of the line sensor 20 by the conveying orthogonal direction width detecting means 22. , Detection time measuring means 47
Then, the detection time of the coin C by the photo sensor 45 is measured, and the coin width C is detected by the conveyance direction width detection means 48 from the detection time and the predetermined conveyance speed of the conveyance means 14.
The main determination means 4 detects the width of the
According to 9, it becomes possible to determine whether or not the coin C is a deformed coin based on the widths of the coins that are normal and the difference should be within the allowable error range. As described above, the deformed coin can be reliably detected by determining whether or not the coin is a deformed coin based on the partial width abnormality caused by the deformation, as in the first embodiment. The effect of can be produced.

Moreover, since the optical path of the photosensor 45 is along the coin transport surface 11a, the width of the coin C in the transport direction, which is determined by the determination means 50 from the time when the optical path is blocked, that is, the non-light receiving time, is upstream. The width of the coin C, which is detected by the line sensor 20 on the side of the coin C, in the direction orthogonal to the conveying direction is shorter than the permissible error, or intermittently short in the same distance as the width in the direction orthogonal to the conveying direction. It is determined that the coin is a deformed coin by detecting that the coin is deformed. Therefore, even when the coin C is deformed such as slightly warped to the extent that it is difficult to detect the abnormality of the diameter, the deformation can be detected.

Next, a modified coin detecting device according to a fourth embodiment of the present invention will be described below with reference to FIG. 13, focusing on differences from the third embodiment. The third
The same reference numerals are given to the same parts as those of the embodiment, and the description is omitted. In the fourth embodiment, the line sensor 2
In addition to the conveyance orthogonal direction width detection means 22 of the third embodiment for detecting the width D ₁ of the coin in the direction orthogonal to the conveyance direction and outputting this to the main determination means 49, The detection time measuring means 23 for measuring the detection time T ₁ of the coin C, which is similar to that of the above embodiment, is connected.

On the other hand, the photosensor 45 is connected to the detection time measuring means 47 for measuring the detection time T ₂ of the coin C according to the third embodiment.
In addition to the conveyance direction width detection means 48 for detecting the width D ₃ of the coin C in the direction along the conveyance direction and outputting this to the main determination means 49, the same as in the third embodiment The main determination means 52 is connected to the main determination means 52, and the detection time measuring means 23 described above is connected to the main determination means 52.

Then, the main judging means 52 detects from the detection time T ₁ of the coin C measured by the detection time measuring means 23 and the detection time T ₂ of the coin C measured by the detection time measuring means 47. It is determined whether or not the coin C is a deformed coin. That is, the main determination means 52 uses T ₁ = T ₂ ± Δ
When t (Δt is an allowable error) is satisfied, it is determined that the detected coin C is a normal coin, that is, it is not a deformed coin, and when the above formula is not satisfied, the detected coin C is a deformed coin. judge.

The main judging means 52 and the above-mentioned main judging means 49 are connected to the final judging means 53.
When the detected coin C is determined to be a modified coin by at least one of the main determination units 49 and 52, the final determination unit 53 finally determines the coin C to be a modified coin, and both of them are determined. When it is not determined that the coin is a deformed coin, it is determined that the coin C is not a deformed coin.

In the fourth embodiment, the detection time measuring means 23, 47, the conveying direction width detecting means 48, the conveying orthogonal direction width detecting means 22, the main judging means 49, 52 and the final judging means 53 are Whether or not the coin C is a deformed coin is determined from the width in the direction along which the coin C is conveyed and the width in the direction orthogonal to the direction in which the coin C is conveyed, and the one light receiving element 20a of the line sensor 20 is used. A determination unit 54 that determines whether or not the coin C is a deformed coin is also configured based on the detection time of the coin C and the detection time of detecting the coin C by the photo sensor 45. The conveying unit 14, the line sensor 20, the light emitting element, and the photo sensor 45 form a deformed coin detecting device.

According to the fourth embodiment having the above-described structure, in addition to the third embodiment, if the determination means 54 is a normal coin, the difference should be within the allowable error range, the detection time. The detection time of the coin C detected by any one of the light receiving elements 20a that first detects the moving coin C of the light receiving elements 20a of the line sensor 20 measured by the measuring means 23, and the detection time measuring means 47. The main determination means 52 also determines whether or not the coin C is a deformed coin based on the detection time for detecting the coin C by the photo sensor 45, and the final determination means 53 determines both main coins. From the judgment results of the judging means 49, 52, it is judged whether or not the coin C is a deformed coin. in this way,
By double detecting the partial width abnormality that occurs due to deformation and determining whether or not the coin is a deformed coin,
The deformed coin can be detected more reliably.

Next, a modified coin detecting device according to a fifth embodiment of the present invention will be described below with reference to FIGS. 14 and 15, 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 is omitted. In the fifth embodiment, the transport means 14 has a pair of pulleys (not shown), a belt 17 hung on these pulleys, and a drive unit that rotates both belts 17 at a constant speed. A line sensor is not provided in the coin passage 11.

Further, both guides are parallel to the conveying surface 11a and are inclined at a predetermined angle with respect to the coin conveying direction in a predetermined direction (the direction in which the downstream side of the coin C in the conveying direction is located on the right side in plan view) and form the same straight line. Through holes 56 and 57 are formed to penetrate the portions 12 and 13, and are parallel to the transport surface 11a and at the same angle to the coin transport direction and at the same angle as the predetermined direction (the coin transport direction). Through holes 58 and 59 that are inclined in the direction in which the downstream side is located on the left side in plan view and form the same straight line and penetrate both guide portions 12 and 13.
And the line connecting the through holes 56 and 57 and the line connecting the through holes 58 and 59 are formed on both guide portions 12, 13
It intersects at the center position between.

Outside the through holes 56 and 57 on both sides in the radial direction of the coin C moving on the transfer surface 11a, lines connecting each other, that is, optical paths, do not interfere with the transfer means 14 and on the transfer surface 11a. A photo of a pair of a light emitting element 61a and a light receiving element 61b which are as close as possible to the transport surface 11a so as to detect the coin C transported by and pass through the through holes 56 and 57 in parallel or coaxial with the axis thereof. A sensor 61 is provided, and a pair of similar light receiving element 62a and light emitting element 62b are also provided outside the through holes 58 and 59.
A photo sensor 62 composed of the photo sensor 61 and the photo sensor 62 is provided.
The line connecting a and the light receiving element 61b and the line connecting the light emitting element 62a and the light receiving element 62b, that is, the respective optical paths, intersect at the center position between the guide portions 12 and 13.

In the photo sensor 61, detection is started from the state where the light receiving element 61b is in the light receiving state, and the light receiving element 61b is detected.
The detection time measuring means 64 for measuring the time from the non-light receiving state to the light receiving state again, that is, the detection time T ₃ of the coin C, is connected as shown in FIG.
In the same manner, the photosensor 62 detects the time T for detecting the coin C.
A detection time measuring means 65 for measuring ₄ is connected.
The detection time measuring means 64 and 65 determine whether or not the detected coin C is a deformed coin based on the detection times T ₃ and T ₄ measured by the detection times T ₃ and 65.
Is connected. The main determination means 66 is T ₃ = T ₄ ±
When Δt (Δt is an allowable error) is satisfied, it is determined that the detected coin C is a normal coin, that is, not a deformed coin, and when the above formula is not satisfied, the detected coin C is a deformed coin. judge.

The line connecting the light emitting element 61a and the light receiving element 61b of each photosensor 61, 62 and the line connecting the light emitting element 62a and the light receiving element 62b are the transport surface 11a.
Therefore, the main determination unit 66 uses the fact that the coin C does not come into contact with the transport surface 11a due to the deformation, and thus the optical path of one of the photosensors 61 and 62 is shut off. That is, the non-light-receiving time is shorter than the time that is possible for coins of all denominations, exceeding the permissible error, or intermittent during the time, and further, one of the photosensors 61 and 62. The time when the optical path is blocked, that is, the non-light receiving time is shorter than the time when the other optical path of each of the photosensors 61 and 62 is blocked, that is, the non-light receiving time, is shorter than the permissible error, or is shortly interrupted during the time. It is determined that the coin is a deformed coin by detecting that the coin is deformed.

Here, the center of the coin C is the photo sensor 6
1 except for passing through the intersection of the optical paths of the photosensor 62 and the photosensor 62, the detection timing of the coin C of the photosensors 61 and 62 is deviated, but the deviation amount of the maximum detection timing is wide in the width of the coin C. The main judging means 66 is known in advance.
Determines that the coins C within the range of the deviation amount are detected. Then, in this case, the feeding timing of the coin C by the separating and feeding means on the upstream side is set to be larger than the deviation amount. Further, if the photo sensors 61 and 62 have the same angle with respect to the transport direction of the coin C and are inclined in the opposite directions, the positions of the coin C in the transport direction can of course be different.

In the fifth embodiment, the detection time measuring means 64, 65 and the main determination means 66 determine that the coin C is moving from the respective detection times of the photosensors 61, 62 of the moving coin C. A determination means 67 for determining whether or not the coin is a deformed coin is configured, and the determination means 67 is provided.
The conveying means 14 and the photo sensors 61 and 62 constitute a deformed coin detecting device.

According to the fifth embodiment configured as described above, the coins C are conveyed one by one by the conveying means 14 to the conveying surface 11.
By moving straight at a constant speed along a, it passes between the light emitting element 61a and the light receiving element 61b of the photo sensor 61 and between the light emitting element 62a and the light receiving element 62b of the photo sensor 62. For the coins C that have passed, the determination unit 67 causes the detection time measurement unit 64 to measure the detection time of the coin C by the photo sensor 61, and the detection time measurement unit 65 causes the detection time of the coin C by the photo sensor 62. Then, the main determination means 66 determines whether or not the coin C is a deformed coin based on the detection times for which the difference should be within the allowable error range for normal coins. In this way, it is possible to reliably detect the deformed coin by determining whether or not the coin is a deformed coin based on the partial width abnormality generated by the deformation.

In addition, the judging means 67 has a time during which the optical path is blocked, that is, a non-light-receiving time, which is shorter than the allowable time for coins of all denominations by an allowable error or shorter than that time. In addition, the time when the optical path of either one of the photosensors 61 and 62 is blocked, that is, the non-light receiving time, is shorter than the permissible error with respect to the time when the other optical path is blocked, that is, the non-light receiving time. It is determined that the coin is a deformed coin by detecting that the coin is short or intermittent during the time. Therefore, even when the coin C is deformed such as slightly warped to the extent that it is difficult to detect the abnormality of the diameter, the deformation can be detected. Moreover, in this case, since the photo sensors 61 and 62 are provided in two pairs with different angles, the deformed coin can be detected more reliably.

By combining the first embodiment and the fifth embodiment, it is possible to provide two pairs of photosensors 61 and 62 on the upstream side or the downstream side of the line sensor 20 in the coin transport direction. Yes (sixth embodiment). In this case, the final judging means is connected to the main judging means 25 of the first embodiment and the main judging means 66 of the fifth embodiment, and the coin C detected by the final judging means is mainly used. If at least one of the determination means 25 and 66 determines that the coin is a deformed coin, the coin C is finally determined to be a deformed coin, and if neither is determined to be a deformed coin, the coin C is not. Will be judged.

Similarly, by combining the second embodiment and the fifth embodiment, two pairs of photosensors 61 and 62 are provided upstream or downstream of the area sensor 32 in the coin transport direction.
It is also possible to provide (7th Embodiment). In this case, the detected coin C is detected by at least one of the main judging means 39 and 66 of the second embodiment and the main judging means 66 of the fifth embodiment. When it is determined that the coin is a deformed coin, the coin C is finally determined as a deformed coin, and when neither is determined as a deformed coin, a final determination unit that determines that the coin C is not connected is connected.

According to the sixth and seventh embodiments as described above, the determining means of the first and second embodiments determines from the respective detection times of the photosensors 61 and 62 of the moving coin C. Also, it is determined whether or not the coin C is a deformed coin. In this way, in addition to comparing the detection time of the two directions that are symmetrical with respect to the transport direction and are symmetrical, it is necessary to determine whether or not the coin is a deformed coin.
The deformed coin can be detected more reliably.

[0062]

As described above in detail, according to the first aspect of the invention, the determining means first detects the moving coin among the detecting elements of the line sensor, and the coin is detected by any one of the detecting elements. The width of the coin in the direction along the conveying direction is detected from the detection time and the conveying speed of the conveying means, and the coins are orthogonal to the conveying direction from the distance between the farthest detection elements that have detected the coin. The width in the direction is detected, and if the coin is a normal coin, it is determined whether or not the coin is a deformed coin from these widths in which the difference should be within the allowable error range. In this way, it is possible to reliably detect the deformed coin by determining whether or not the coin is a deformed coin based on the partial width abnormality generated by the deformation.

According to the second aspect of the invention, the determining means determines whether or not the coin is a deformed coin from the pattern data of the coin detected by the detection element of the area sensor. In this way, it is possible to reliably detect a deformed coin by determining whether or not the coin is a deformed coin based on the abnormal shape caused by the deformation. Moreover,
Since the transport speed is irrelevant to the detection of deformed coins, the deformed coins can be reliably detected even if the transport means cannot transport the coins at a constant speed due to deformation of the coins or the like.

According to the third aspect of the present invention, the judging means detects the width of the coin in the direction along the conveying direction from the detection time for detecting the moving coin by the photosensor and the conveying speed by the conveying means. Detecting the width of the coin in the direction orthogonal to the conveying direction from the distance between the furthest ones of the detection elements of the line sensor that has detected the coin, if the coin is a normal coin, the difference should be within the allowable error range. Whether or not the coin is a deformed coin is determined from the width. In this way, it is possible to reliably detect the deformed coin by determining whether or not the coin is a deformed coin based on the partial width abnormality generated by the deformation. Moreover, since the line connecting the light-emitting element and the light-receiving element of the photo sensor is along the transport surface of the coin, the determination means detects that the coin does not come into contact with the transport surface due to deformation. The width of the coin in the conveying direction, which is obtained from the time, is shorter than the allowable error with respect to the width in the direction orthogonal to the coin detecting direction detected by the line sensor, or approximately the width in the direction orthogonal to the conveying direction. Even when the coin is deformed such as being slightly warped to the extent that it is difficult to detect an abnormality in the diameter due to short interruptions in the same distance, the deformation can be detected.

According to the fourth aspect of the invention, if the judging means is a normal coin, the difference should be within the allowable error range.
From the detection time of the coin by any one of the detection elements that first detects the moving coin among the detection elements of the line sensor, and the detection time when the coin is detected by the photo sensor, the coin is a deformed coin. It will be determined whether or not. In this way, the deformed coin can be detected more reliably by double detecting the partial width abnormality caused by the deformation and determining whether or not the coin is a deformed coin.

According to the invention described in claim 5, if the judging means is a normal coin, the difference should be within the allowable error range.
Whether or not the coin is a deformed coin will be determined from the detection time of each moving sensor of the moving coin. In this way, it is possible to reliably detect the deformed coin by determining whether or not the coin is a deformed coin based on the partial width abnormality generated by the deformation. Moreover, since the line connecting the light-emitting element and the light-receiving element of each photosensor is along the transportation surface of the coin, the determining means uses the fact that the deformation causes a portion where the coin does not contact the transportation surface. It is detected that the time when the optical path of each photo sensor is cut off, that is, the non-light receiving time is shorter than the possible time for coins of all denominations, exceeding the permissible error, or being interrupted for a short time during the time. It will be judged as a deformed coin. Therefore, even when the coin is deformed such as being slightly warped to the extent that it is difficult to detect an abnormality in the diameter, the deformation is detected. Moreover, since two pairs of photosensors are provided at different angles, the deformed coin can be detected more reliably.

According to the sixth aspect of the invention, the determining means determines whether or not the coin is a deformed coin also from the detection time of each moving photocoin in each photosensor. In this way, in addition to comparing the detection time of the two directions that are symmetrical with respect to the transport direction and are symmetrical, it is necessary to determine whether or not the coin is a deformed coin.
By detecting the deformed coin by double detection, it is possible to detect the deformed coin more reliably.

According to the seventh aspect of the present invention, the determining means determines whether or not the coin is a deformed coin from the detection time of each moving photocoin in each photosensor. In this way, in addition to comparing the detection time of the two directions that are symmetrical with respect to the transport direction and are symmetrical, it is necessary to determine whether or not the coin is a deformed coin.
By detecting the deformed coin by double detection, it is possible to detect the deformed coin more reliably.
