It is configured to start a symbol variation effect on the device and to pay out a pachinko ball as a prize ball. Then, when various kinds of game effects such as reach effects due to symbol fluctuations are made on the symbol display device, and a so-called jackpot is generated by stopping the symbols in the symbol combination on the symbol display device, a special game board is provided on the game board. The winning device is configured to be opened to give a chance to win a large number of prize balls.

  In the pachinko machine, various control devices in which various control boards for controlling the progress of a game, the payout of prize balls, and the like are housed in a board case are arranged on the installation member (for example, Patent Document 1). reference). Since the ROM storing the program related to the game content is mounted on the control board, the upper case and the lower case are prevented in order to prevent the control board from being replaced with an unauthorized control board including the ROM storing the illegal program. In the substrate case including the case, a configuration is adopted in which attachment portions provided at the end portions of both cases are connected by screws that are difficult to rotate in the opening direction. That is, the board case having such a configuration cannot be opened unless the screwed mounting portion is broken, so that it can be prevented from being exchanged with an unauthorized control board, and a trace remains at the time of breakage. I can recognize that.

An engaging portion 51 is provided. Further, the fastening portion 50 is connected to the other inner side surface facing the inner side surface provided with the engaged portion 51 inside the fastening hole 50a, from the insertion port portion 50b to the position facing the engaged portion 51. An engagement groove 50c extending therebetween is formed, and the second engagement piece 54 is inserted into the engagement groove 50c.

  As shown in FIG. 11, the fastening band 47 is inserted when the insertion end side of the insertion portion 48a is inserted into the fastening hole 50a from the insertion port portion 50b and the engaging portion 49 is engaged with the engaged portion 51. Further, the position of the second engagement piece 54 inserted into the engagement groove 50c is abutted against the bottom portion of the engagement groove 50c, and the protruding end of the first engagement piece 53 is connected to one of the fastening holes 50a. Displacement in the thickness direction of the insertion portion 48a (displacement in the direction in which the engagement between the engaged portion 51 and the engaging portion 49 is released) is regulated while being in contact with the inner side surface of the insertion portion 48a. The part 51 and the engaging part 49 are engaged and held. This makes it extremely difficult to remove the insertion portion 48a inserted into the fastening hole 50a from the fastening hole 50a, so that the insertion portion 48a can be retained from the fastening hole 50a. Further, in a state in which the engaged portion 51 and the engaging portion 49 are engaged, the lid portion 52 provided in the insertion portion 48a is accommodated in the insertion port portion 50b to close the insertion port portion 50b, and a fastening hole It is configured to prevent the act of releasing the engaged state between the engaged portion 51 and the engaging portion 49 by inserting a tool such as a screwdriver from the insertion port portion 50b side with respect to 50a.

  It should be noted that the distance between the inner surface provided with the engaged portion 51 and the engaging groove 50c in the mouth portion on the opposite side of the insertion hole portion 50b in the fastening hole 50a is determined by the engaging portion 49 and the first engaging piece. It is set to a value that does not allow insertion of the insertion portion 48a at the portion where 53 is provided. Further, in a state where the engaged portion 51 and the engaging portion 49 are engaged, the insertion end side of the insertion portion 48a is predetermined outward from the mouth portion on the opposite side of the insertion hole portion 50b in the fastening hole 50a. While extending by the length, the gap defined between the inner side surface defining the mouth portion and the outer surface of the insertion portion 48a is set to be very small.

  The length from the other end side of the fastening portion 50 to the one end side of the restricting portion 48 b is the same as that of the first through hole 44 formed in the second fixing portion 40 of the substrate case 31 and the holding portion 45 of the installation member 28.

Is provided. In the following description, the infrared ray irradiated from the outside to the identification unit 55 is referred to as “incident infrared ray”, and the infrared ray emitted from the identification unit 55 by the incident infrared ray is referred to as “excitation infrared ray”. The identification unit 55 according to the embodiment is configured to be excited by incident infrared rays in a predetermined wavelength region and emit light in a specific wavelength region different from the incident infrared rays. For example, the identification unit 55 is excited to incident infrared rays of 800 nm and excited at 1000 nm. Infrared rays are emitted.

The identification unit 55 is a portion where infrared ink that is excited by incident infrared rays and emits light in a specific wavelength range different from the incident infrared rays is kneaded, and the identification unit 55 is colorless and transparent or a fastening band 47 to be applied. It is desirable that the same color be used so that the appearance of the fastening band 47 is not affected. Infrared inks include phosphors based on ZnS and doped with emission centers such as Nd, phosphors doped with oxides such as WO ₄ , P ₄ O ₁₂ , and Mo ₄ O _16. , And a phosphor obtained by substituting a part of Nd with Y, Sc, La, Ce, or the like. The identification unit 55 may include a resin such as a polyester resin, a polyurethane resin, a polycarbonate resin, an acrylic resin, and a phenol resin as a binder to which an identification material made of a phosphor is attached. This binder transmits infrared rays. It does not prevent it.

In addition, the identification unit 55 is provided in the regulating unit 48b facing the rear side in the fastening band 47 in a state where the installation member 28 and the substrate case 31 are connected so that the inspection with the inspection device 57 can be easily performed. is there.

(About inspection device 57)
Next, the inspection device 57 that inspects the suitability of the identification unit 55 will be described. As shown in FIGS. 12 and 13, the inspection device 57 includes an irradiation unit 58 that irradiates the identification unit 55 with incident infrared rays, a detection unit 59 that detects excitation infrared rays emitted from the identification unit 55, and the detection unit 59. Are provided with a collation unit 60 that collates the excitation infrared light detected in step 1 with a collation standard set in advance, and a notification unit 61 that notifies predetermined information to the outside based on the collation result of the collation unit 60. The inspection device 57 includes an operation unit 62 that can be operated by a fingertip by the inspector, and can operate the irradiation unit 58 to irradiate incident light or stop irradiation by operating the operation unit 62. In the inspection device 57, incident infrared rays are irradiated from the outside of the fastening band 47, and inspection is performed based on the excitation infrared rays emitted from the identification unit 55. The inspection device 57 operates the irradiation unit 58, the detection unit 59, the verification unit 60, and the notification unit 61 by the power of a battery (not shown) stored in the housing 57a.

  As shown in FIG. 12, the inspection device 57 is unitized by providing an irradiation unit 58, a detection unit 59, a collation unit 60, a notification unit 61, and an operation unit 62 in a portable housing 57 a, An inspector can carry the inspection device 57 and inspect the fastening band 47. The housing 57a of the embodiment is formed in a rectangular box shape (see FIG. 12). The inspection device 57 is provided such that the irradiation unit 58 and the detection unit 59 face the end surface (referred to as an inspection end surface) of the housing 57a, and the inspection device 57 performs the inspection with the inspection end surface facing the fastening band 47. It has become.

  The irradiation unit 58 irradiates the fastening band 47 with incident infrared light, and a light emitting diode, for example, is used. The irradiation unit 58 of the embodiment is configured to continuously irradiate incident infrared rays in a certain wavelength range that can be reflected, absorbed, and emitted by the identification material constituting the identification unit 55 based on the ON operation of the operation unit 62. The irradiation is stopped by turning off the operation unit 62.

  The detection unit 59 is provided so as to face the same surface as the end surface of the housing 57a facing the irradiation unit 58, and detects the excitation infrared ray of the identification material excited by the incident infrared ray irradiated from the irradiation unit 58. Yes. As the detection unit 59, a photodiode, a phototransistor, a CCD, or the like can be used. In the embodiment, a photodiode is employed as the detection unit 59. In addition, the detection unit 59 is provided with a filter that transmits only infrared rays in a specific wavelength range emitted from the identification unit 55, and the detection unit 59 is configured to detect infrared rays in the specific wavelength range. Here, the incident infrared ray irradiated from the irradiation unit 58 is reflected or absorbed (modulated) by a part other than the identification unit 55, so that the infrared ray other than the specific wavelength range emitted by the identification material, such as the wavelength of the incident infrared ray irradiated. However, it may be returned from the inspection target. Like the detection unit 59 of the embodiment, the identification unit 55 is configured to detect only a specific wavelength region (for example, 1000 nm) emitted from the identification unit 55 when excited by incident infrared rays (for example, 800 nm) from the irradiation unit 58. It is possible to prevent false detection that detects other than the above.

  The verification unit 60 is electrically connected to the detection unit 59 (see FIG. 13), and an excitation infrared detection signal is input from the detection unit 59. The matching unit 60 converts the detected light intensity of the excitation infrared light in a specific wavelength range transmitted by the filter into a numerical value, and sets and stores a reference for comparison, and matches the detected signal value converted into a numerical value by the converting unit 60a. Comparison judging means 60b for judging suitability by comparing with a reference. In the comparison determination means 60b of the embodiment, when the incident infrared ray is irradiated from the irradiation unit 58 to the fastening band 47 provided with the appropriate identification unit 55, the detection signal of the received light intensity to be detected by the detection unit 59 Value (set received light intensity) is stored with a predetermined width in consideration of variation in the application amount of the identification material, variation in irradiation intensity of incident infrared rays in the irradiation unit 58, stability and attenuation of incident infrared rays, and the like. Yes. The comparison determination unit 60b compares the value of the detected light reception intensity quantified by the conversion unit 60a and the value of the set light reception intensity. If the value of the detected light reception intensity is equal to or greater than the value of the set light reception intensity, the comparison determination unit 60b A good judgment signal is output. On the other hand, the comparison / determination means 60b compares the value of the detected light reception intensity quantified by the conversion means 60a with the value of the set light reception intensity, and notifies if the value of the detected light reception intensity is lower than the value of the set light reception intensity. No signal is output to the unit 61. Further, the comparison / determination means 60b compares the value of the detected light reception intensity quantified by the conversion means 60a with the value of the set light reception intensity. If the detected light reception intensity is higher than a predetermined upper limit value (upper limit value> set light reception intensity) set in the comparison determination unit 60b, no signal is output to the notification unit 61.

  The notification unit 61 includes a light emitting unit 61a made of an LED or the like and a sound output unit 61b, and is configured to notify at least one of normal and abnormal information by both light and sound. When the good determination signal is input from the comparison determination unit 60b, the notification unit 61 emits light from the light emitting unit 61a, and a mechanical sound such as a beep and a voice are output from the sound output unit 61b. Based on the light and sound notification by 61, it can be determined that the inspection object is a genuine product. On the other hand, when the good determination signal is not input from the comparison determination unit 60b, the notification unit 61 turns off the light emitting unit 61a and outputs nothing from the sound output unit 61b. Thus, it can be determined that the inspection target is not a regular product. Further, when the identification information pattern is formed by the identification unit 55 in the fastening band 47, predetermined identification information is obtained by detecting the excitation infrared ray by moving the inspection end face of the inspection device 57 along the front side of the fastening band 47. A notification of the pattern is made, and it can be determined whether or not the product is genuine by this notification pattern.

  The inspection device 57 is adapted to the identification portion 55 of the fastening band 47 connecting the installation member 28 and the substrate case 31, and the excitation infrared ray having a wavelength range of incident infrared rays irradiated from the irradiation portion 58 or a wavelength range different from the incident infrared rays. In order to detect this, collation criteria for the detection unit 159 and the collation unit 60 are set. Thus, the fastening band 47 and the inspection device 57 capable of inspecting the fastening band 47 are associated with each other, and the fastening band 47 and the inspection device 57 constitute an inspection system. In addition, since the test | inspection apparatus 57 of an Example can test | inspect in the state isolate | separated from the fastening band 47, it is not necessary to set it as the special shape according to the fastening band 47, and versatility is high.

(About the guide portion 56 of the base member 33)

A guide portion 56 is provided for guiding the insertion. As shown in FIG. 5, the guide portion 56 includes a guide surface 56a extending in the left-right direction, and a pair of guide pieces 56b formed along the upper and lower edge portions of the guide surface 56a and extending rearward. 56b, and a guide groove 56c is formed by the guide surface 56a and the pair of guide pieces 56b, 56b. As shown in FIG. 6, the end portion of the guide surface 56a on the holding portion side is positioned in front of the rear surface of the base portion 45a in the holding portion 45, and the end portion of the guide surface 56a on the second fixed portion side is It faces the front side of the second fixing portion 40. Further, the predetermined area on the second fixing portion side in the guide surface 56 a is formed so as to curve backward as it approaches the second fixing portion 40, and its end portion defines the first through hole 44. It is set to be located on the inner side (right side) of the right inner surface. Accordingly, the insertion portion 48a of the fastening band 47 inserted from the right side into the second through hole 46 is guided by the guide surface 56a and can be smoothly inserted into the first through hole 44.

  Each of the guide pieces 56a, 56a is formed to be aligned with the corresponding guide walls 45c, 45c of the holding portion 45 in the left-right direction, and is inserted into the second through hole 46 from the right side through an insertion portion 48a of the fastening band 47. Is displaced by a pair of guide pieces 56a, 56a. Further, the end portions of the pair of guide pieces 56a, 56a facing the front side of the second fixing portion 40 are set so as to face the inside of the first through hole 44, and are moved while being regulated by the guide pieces 56a, 56a. The insertion portion 48a to be guided can be reliably guided to the first through hole 44.

(Operation of Example)
Next, the operation of the pachinko machine 10 according to the embodiment will be described.

  When the base member 33 is attached to the installation member 28, the engaged member provided with the first engagement protrusion 34 provided on the installation member 28 while the front surface of the base member 33 is opposed to the back surface of the installation member 28. With the base member 33 facing the right side of the receiving portion 36a, the base member 33 is moved to the left with respect to the installation member 28, so that the space between the back surface of the installation member 28 and the engaged receiving portions 36a, 36a. The first engaging protrusion 34 is inserted, whereby the left end portion of the base member 33 is locked to the installation member 28. Further, a restricting protrusion 34a provided on the first engaging protrusion 34 is fitted between the pair of engaged receiving portions 36a and 36a, and the left end portion of the base member 33 is in the left, front and rear, and up and down directions. It is positioned with respect to the installation member 28 in a state in which movement to is restricted. At this time, the first fixing portion 35 of the base member 33 is aligned with the rear side of the first fixed portion 37 of the installation member 28, so that the connecting tool 38 supported by the first fixing portion 35 is used. By connecting the first fixing part 35 to the first fixed part 37, the base member 33 is positioned and fixed at a predetermined position with respect to the installation member 28. The base member 33 can be removed from the installation member 28 by releasing the connection by the connection tool 38.

  When the main controller 32 is attached to the base member 33 positioned and fixed to the installation member 28, the front surface of the substrate case 31 is opposed to the back surface of the base member 33, and the second engaging protrusion 39 is disposed on the base member 33. The board case 31 is moved to the left side with respect to the base member 33 with the insertion receiving portion 41 provided on the right side of the insertion receiving portion 41 provided on the right side of the insertion receiving portion 41. The engaging protrusion 39 is inserted (see FIG. 6), whereby the left end portion of the substrate case 31 is positioned with respect to the base member 33 in a state where movement of the board case 31 to the left, back and forth and up and down is restricted. Is done. At this time, the second fixing portion 40 of the substrate case 31 is substantially aligned with the rear side of the second fixed portion 42 of the base member 33, and the right end portion of the substrate case 31 is brought close to the base member 33. Thus, the locking portion 43b of the fixture 43 supported by the second fixing portion 40 is inserted into the hole of the fixed cylinder portion 42a in the second fixed portion 42 (see FIG. 7). Then, by pressing the operating portion 43a of the fixture 43 in this state, the locking portion 43b is displaced to the fixed position and engaged with the fixed cylinder portion 42a, and the substrate case 31 (main control device 32) is The member 33 is positioned and fixed.

  Next, a process of connecting the substrate case 31 and the installation member 28 with the fastening band 47 will be described. With the front surface of the fastening band 47 facing the back surface of the installation member 28, the insertion end of the insertion portion 48 a in the fastening band 47 is in contact with the rear surface of the base portion 45 a in the holding portion 45. Move to the left. Since the guide part 45c, 45c is provided in the base part 45a along the upper and lower end edges, the insertion part 48a is not greatly displaced in the vertical direction by the upper and lower guide walls 45c, 45c. Securely inserted. The insertion end of the insertion portion 48a inserted through the second through hole 46 moves to the left while being guided by the guide surface 56a of the guide portion 56 and the guide pieces 56b and 56b, and is inserted into the first through hole 44. And extends backward from the second fixing portion 40. The end of the guide portion 56a on the guide portion 56a on the guide portion 56a is positioned on the front side with respect to the rear surface of the stand portion 45a, and is inclined to the side away from the second through hole 46 in the first through hole 44. Since the end portion on the first through hole side of the guide surface 56a is displaced inside the first through hole 44 with respect to the inner side surface, the insertion portion guided along the rear surface of the base portion 45a and the guide surface 56a. The insertion end of 48 a is smoothly inserted into the first through hole 44 without hitting the side end of the guide portion 56 or the front surface of the second fixing portion 40. That is, the side on which the operator inserts the fastening band 47 into the first and second through holes 44 and 46 due to the presence of the arch portion 45b of the holding portion 45 and the second fixing portion 40 (the back side of the installation member 28). Even if the relationship between the through-holes 44 and 46 and the insertion portion 48a is difficult to see, the insertion portion 48 can be easily inserted into the through-holes 44 and 46, and the workability is good.

  The insertion part 48a extending rearward from the second fixing part 40 is inserted into the fastening hole 50a of the fastening part 50 from the insertion port part 50b side. Further, by further pulling the insertion portion 48a extending outward from the mouth portion on the opposite side of the insertion hole portion 50b in the fastening hole 50a, the engagement portion 49 provided in the insertion portion 48a is moved into the fastening hole 50a. Engage with the engaged portion 51. In a state where the engaging portion 49 is engaged with the engaged portion 51, as shown in FIG. 11, the second engaging piece 54 inserted into the engaging groove 50c comes into contact with the bottom portion of the engaging groove 50c. In addition to being regulated in position, the protruding end of the first engagement piece 53 comes into contact with one inner surface of the fastening hole 50a, and the engagement between the engaged portion 51 and the engaging portion 49 is released. The displacement of the insertion portion 48a is restricted. That is, the fastening band 47 is in a state where the insertion portion 48a is inserted into the first through hole 44 and the second through hole 46, and it is difficult to remove the insertion portion 48a from the fastening hole 50a. Retained. This makes it difficult to remove the main controller 32 (substrate case 31) from the base member 33 (installation member 28) unless the fastening band 47 is cut and pulled out from the through holes 44, 46. It is possible to suppress unauthorized removal of 32 and replacement with a fake product. In addition, when the fastening band 47 is cut, unless a new fastening band is attached, a fraudulent trace remains due to the absence of the band. Therefore, it is easy to find an illegal act.

  Further, the fastening band 47 includes an identification unit 55 that emits excitation infrared light excited by incident infrared light. Therefore, by irradiating the incident infrared light toward the fastening band 47, the proper fastening band 47 can be used. For example, if the identification unit 55 emits light in the infrared region, but is replaced with an unauthorized fastening band that imitates only the appearance and does not include the identification unit, infrared rays that satisfy the verification criteria are emitted from the fastening band. Absent. That is, it is possible to easily confirm whether or not the fastening band 47 irradiated with the incident infrared rays is a genuine product by detecting the excitation infrared ray emitted by the identification unit 55 and collating it with the collation reference. It can be seen that the main controller 32 connected is a genuine product. Here, if the identification part 55 emits the excitation infrared rays of a wavelength range different from incident infrared rays, it can distinguish from the mere reflection of the irradiated incident infrared rays, and can identify the identification part 55 accurately.

  Since the identification unit 55 of the embodiment is excited by incident infrared rays and emits excitation infrared rays, the identification unit 55 itself cannot be visually observed regardless of whether or not the incident infrared rays are irradiated. Those who do not have 57 do not know the existence of the identification unit 55. In this way, the identification unit 55 does not emit light in a manner that can be identified by human eyes even when incident infrared rays or light rays other than incident infrared rays (visible light or ultraviolet rays) are applied. Therefore, it is difficult to forge the fastening band 47 of the fraudster.

  The fastening band 47 is formed by forming the identification part 55 in a predetermined pattern, so that whether or not the fastening band 47 is a genuine product is determined based on an identification information pattern formed by excitation infrared rays emitted from the identification part 55. be able to. In addition, by changing the identification information pattern of the identification unit 55 by, for example, a lot, model, component, etc., only a person who has identification information pattern information matched to these lot, model, component, etc. is a fastening band. 47 authenticity determination can be performed, and illegal acts such as duplication of fraudsters can be made more difficult. In addition, in the fastening band 47 of the embodiment, the identification portion 55 is provided on the restriction portion 48b that faces the rear side in a state where the installation member 28 and the substrate case 31 are connected to each other because it is difficult to bend in the plate thickness direction. Therefore, it is easy to determine the authenticity of irradiating the identification unit 55 with incident infrared rays.

  Here, it is conceivable that an unauthorized person removes the insertion portion 48a from the fastening hole 50a without cutting the fastening band 47 and comprehending the engagement between the engaged portion 51 and the engaging portion 49. . In this case, the opening size of the mouth portion on the side where the insertion end side of the insertion portion 48a extends from the fastening hole 50a is small, and a tool is inserted from the mouth portion side to engage the engaged portion 51 and the engaging portion 49. It is extremely difficult to release the engaged state. In addition, as shown in FIG. 6, the fastening band 47 of the embodiment is difficult to bend the fastening portion 50 and the regulating portion 48b facing the rear side of the holding portion 45 and the second fixing portion 40 in the thickness direction. The length obtained by adding the regulating portion 48b is the opposite end portion between the second fixing portion 40 in which the first through hole 44 is formed and the holding portion 45 (arch portion 45b) in which the second through hole 46 is formed. It is set longer than the distance between them. Accordingly, the fastening band 47 is rotated so as to be inserted into the second through hole 46 and the first through hole 44 while forcibly bending the restricting part 48b, and the insertion port 50b of the fastening hole 50a is moved to the holding part 45 and the second fixing part. It is difficult to face the rear side of 40 (the side on which it is easy for a cheating person to insert a tool into the fastening hole 50a), and cheating can be suppressed. Even if the insertion port portion 50b can face the rear side of the holding portion 45 or the second fixing portion 40, the insertion port portion 50b is blocked by the lid portion 52. It is extremely difficult to forcibly release the engaged state between the engaged portion 51 and the engaging portion 49 by inserting the screw into the fastening hole 50a, and it is possible to reliably suppress illegal acts.

  In addition, the engaging portion 49, the lid 52, the first engaging piece 53, and the second engaging piece 54 are formed thick in the insertion portion 48a inserted through the fastening hole 50a of the fastening portion 50. Since it is difficult to bend in the thickness direction, it is more difficult to forcibly release the engaged state between the engaged portion 51 and the engaging portion 49 by the tool. However, the restricting portion 48b in the insertion portion 48a and the thick portion where the engaging portion 49, the lid portion 52, the first engaging piece 53 and the second engaging piece 54 are formed are thicker than the thick portion. Since it is connected with a thin part with a thin predetermined length dimension, even if a restricting part 48b or a thick part that is difficult to bend in the plate thickness direction is provided, the thin part is bent when the fastening band 47 is annular. There is no decline in sex.

In another embodiment, the locking portion 43b of the fixing tool 43 is the second portion. The dimension is set such that it cannot be removed from the fixed cylinder portion 42a of the fixed portion 42. Accordingly, the movement of separating the substrate case 31 rearward from the installation member 28 is restricted by the fastening band 47, and the locking portion 43 b of the fixture 43 is removed from the fixed cylinder portion 42 a of the second fixed portion 42. Can be blocked. Accordingly, the substrate case 31 cannot be moved laterally (rightward) to remove the second engagement protrusion 39 from the engagement hole 41a, and the substrate case 31 is attached to the installation member 28 by the fastening band 47. An illegal act of removing the substrate case 31 from the installation member 28 can be suppressed while being connected. Even if the fixture 43 is removed from the second fixing portion 40, the lateral movement of the substrate case 31 is restricted when the holding portion 45 and the second fixing portion 40 are connected by the fastening band 47. Therefore, even in this case, it is possible to prevent the second engagement protrusion 39 from being removed from the engagement hole 41a, and the substrate case 31 remains connected to the installation member 28 with the fastening band 47. Further, an illegal act of removing the substrate case 31 from the installation member 28 can be suppressed.
