Description

  The present invention relates to a gaming machine that starts a game upon receiving a medal, and more particularly to medal detection in the gaming machine.

  As a gaming machine using medals, for example, a slot machine is well known, and a game starts when a medal is inserted. At the start of the game, in addition to detecting that a medal has actually been inserted, it is also required to determine the authenticity of the inserted medal. Various proposals have been made to meet such demands (for example, Patent Document 1).

JP 2005-261778 A

  In this patent document, the light emitted from the light emitting part is reflected by a detection object, and the attenuation of reflected light when the light is reflected by the surface of a foreign object other than a medal is used. And, as a result of such reflected light attenuation between the medal and the other foreign matter, there is a difference in the light receiving level at the light receiving unit when there is no medal and when there is a transparent foreign matter. Used for detection and authenticity determination (foreign matter determination).

  In addition, the emission of light at the light emitting unit is pulsed based on the pulse signal output of a fixed period, and synchronization of the light emission pulse and the light reception signal pulse at the light receiving unit improves the accuracy of foreign object determination Is planned.

  By the way, it is also expected that a light emitting foreign matter (light emitting foreign matter) that emits light and outputs a light reception signal to the light receiving portion is thrown into the gaming machine instead of a medal. Such a luminescent foreign material is configured to emit light in a pulse shape, and its pulse cycle may be adjusted. Then, if the light emission period of the luminescent foreign object coincides with the period of the pulse signal that causes the emission of the light emitting unit in the gaming machine, the luminescent foreign object will pretend to be a medal and erroneously determine the luminescent foreign object as a medal. There is a risk that it will end. In addition, it is also expected that foreign substances that can be switched between translucency and non-translucency, such as liquid crystal panel foreign substances, are introduced. Such a liquid crystal panel foreign matter may be adjusted so that a medal passes through the non-translucent part while switching the non-translucent part to the translucent part. Due to the movement of the non-translucent portion, the liquid crystal panel foreign material falsifies the medal, and there is a fear that the liquid crystal panel foreign material is mistakenly determined as a medal.

  The present invention has been made to solve the above-described problems in medal detection in a gaming machine using medals, and an object thereof is to improve the reliability of foreign object detection.

  In order to solve at least a part of the problem, the gaming machine of the present invention includes at least three or more detectors along the medal path when detecting medals passing through the medal path. The presence / absence of the detection target in is detected at a different position on the medal path. Then, at least two detectors effective for the detection of the detection object are set out of the three or more detectors, and based on the detection status of the detector that is effective for the detection of the detection object. Detecting whether the detection object is a genuine medal, and determining whether to allow the game machine to continue and stop the game according to the detection result.

  In other words, each time the detector is set as described above, the combination of detectors that are effective for detecting the detection object (hereinafter also simply referred to as an effective detector) changes. Corresponding to the combination of the detectors, it is difficult to simulate the output status of the effective detector of the combination. Therefore, the detection situation with two or more effective detectors when a genuine medal M passes the medal path, and the detection situation with two or more effective detectors when a foreign object is inserted instead of the medal M And almost no match. For this reason, the reliability of foreign object detection can be further improved.

  Such an effective detector can be set at a predetermined timing in addition to setting the number of effective detectors. For example, the power-on timing of the gaming machine, the operation timing of the setting operation unit by the user, the predetermined time A combination of effective optical systems may be set at at least one of the timing of each cycle and the transition timing to a predetermined gaming state (for example, a big win) in the gaming machine. In this way, the combination of effective detectors changes at each set timing, so that it is possible to further improve the reliability of foreign object detection.

  In addition, the gaming machine of the present invention may be configured as follows. For example, various types of detectors such as an optical type and a magnetic type can be adopted as the detector. However, since the optical detector is widely used because of easy maintenance, the aspect taken in the present invention is As the three or more detectors, an optical system including a light emitting unit that emits light and a light receiving unit that outputs a light reception signal corresponding to the amount of light received, and the optical system passes through the medal path. The detection object is irradiated with light from the light emitting unit to obtain the light reception signal from the light receiving unit. In addition, at least two of the three or more optical systems that are effective for detecting the detection object are set, and the optical system included in the optical system that is effective for detection of the detection object is included. Based on the output status of the received light signal from the light receiving unit, it is detected whether the detection target is a genuine medal, and the game machine is allowed to continue and the game is stopped according to the detection result. .

  That is, each time the optical system is set as described above, the combination of optical systems that are effective for detecting a detection target (hereinafter also simply referred to as an effective optical system) changes, so that it emits light and sends a light reception signal to the light receiving unit. Whether it is a light emitting foreign matter to be output or a liquid crystal panel foreign matter that moves a non-translucent part, it is difficult to output a light reception signal to the light receiving portion of the optical system of the combination in correspondence with such a combination of optical systems. It is. Therefore, when the genuine medal M passes through the medal path, the output state of the light receiving signal at the light receiving unit in the two or more effective optical systems, and when the light emitting foreign matter or the liquid crystal foreign matter is inserted instead of the medal M The output state of the received light signal at the light receiving unit in two or more effective optical systems hardly coincides. For this reason, the reliability of foreign object detection can be further improved.

  In addition, the gaming machine of the present invention may be configured as follows. For example, the light emitting unit for each optical system emits light of a different color for each optical system, and the light receiving unit for each optical system emits the light emitted by the light emitting unit in the optical system to which the light receiving unit belongs. A first light receiving unit that receives the light of the second color, and a second light receiving unit that receives light of other colors. In this way, each time the effective optical system is set, the combination of the colors of light emitted by the light emitting unit of the set effective optical system (hereinafter, this color is also referred to as the effective color) changes. Further, if light of a color other than the effective color emitted by the light emitting unit of the effective optical system is emitted, light of other colors is received by the second light receiving unit, but the light emitting unit of the effective optical system Therefore, the light reception by the second light receiving portion does not normally occur.

  In many cases, the luminescent foreign matter emits light of a single color (for example, white light). Therefore, when the luminescent foreign matter is present in the effective optical system, light is received by the first light receiving unit in the effective optical system. In addition, the second light receiving unit that receives light of other colors also receives light. Therefore, the light receiving states in the first and second light receiving units in the respective effective optical systems by the genuine medal M in the two or more effective optical systems, and the respective effective optics by the light emitting foreign matter in the two or more effective optical systems. The light receiving state of the first and second light receiving units in the system is significantly different depending on whether light is received by the second light receiving unit. In addition, the combination of two or more effective optical systems is not uniform and changes with each setting, so the combination of two or more light emitting locations in a light-emitting foreign object matches the combination of two or more effective optical systems. There is little to do.

In determining the color of light from the light emitting unit in each effective optical system, so-called RGB filters that are the three primary colors of light are installed in the light path of the light emitting unit for each optical system, or the RGB light source is emitted. The color of the light from the light emitting unit may be set by adjusting the output of each light emitting source. In addition, the first light receiving unit that receives light of the effective color can be provided with a filter of one color of RGB, for example, so as to receive the light that has passed through the filter. The second light receiving unit can receive light of a color defined by the filter with a filter having a different color from the first light receiving unit. For example, in an effective optical system having a light emitting unit that emits red light, a first light receiving unit including a red filter and a second light receiving unit including a blue filter are prepared. In this case, in this effective optical system, light is received by the first light receiving unit and light is not received by the second light receiving unit, but the light emitting foreign matter emits white light in the effective optical system. In addition, since the light reception occurs in both the first light receiving unit and the second light receiving unit, it is possible to detect the light emitting foreign matter with high reliability. In addition to the difference in the light receiving state, as described above, the reliability of the detection of the light emitting foreign matter can also be improved in terms of the difference in the combination of the effective optical system and the combination of the light emitting portions in the light emitting foreign matter.
The present invention can be applied to a medal detection device and a medal detection method passing through a medal path in addition to the gaming machines described above. The medal detection device and the detection method of the present invention can also improve the reliability of foreign object detection. Further, not only the optical detector but also other types of detectors such as a magnetic type can be used.

It is explanatory drawing which shows roughly the structure of the optical system in a modification.

  Hereinafter, embodiments of the present invention will be described based on examples. In this embodiment, a slot machine 100 which is an example of a gaming machine in which medal detection is indispensable will be described. 1 is a perspective view showing a schematic configuration of the slot machine 100, and FIG. 2 is a perspective view showing an outline of an internal structure of the slot machine 100. As shown in FIG.

  As shown in the figure, the slot machine 100 is provided with a front door 103 that can be opened and closed with respect to a hollow box-shaped main body 102, and has a substantially rectangular shape when viewed from the front. The main body 102 is a member constituting the skeleton of the slot machine 100 and houses various devices necessary for the slot game. However, since the main body 102 is not directly related to the gist of the present invention, only the detailed details will be described.

  As shown in FIG. 2, the main body 102 is provided with various symbols and the like on the upper upper part thereof and is rotatably provided with three rotating drums 111, and a hopper device 112 and a power supply box 113 are provided on the lower inner part thereof. The hopper device 112 pays out medals in the auxiliary tank 112a for storing medals to the medal payout opening 114 on the front door 103 side. The power supply box 113 supplies power to various devices including the control device 120 that controls the game of the slot machine 100.

  The front door 103 is provided with a window 103a on the front surface of each of the rotating drums 111, and receives medals from a button group operated by a player, a line indicator lamp, a medal insertion slot 104, and a medal payout opening 114. It has a medal tray 115 and the like. Further, the front door 103 has, on the rear side thereof, a key cylinder 118 for locking the door, a medal identification mechanism 200, a medal supply path 116, a medal discharge path 117, and the like in addition to the control device 120 described above. The medal identification mechanism 200 also functions to distribute medals inserted from the medal insertion slot 104 to the medal supply path 116 and the medal discharge path 117. That is, the medal identification mechanism 200 has a well-known distribution mechanism that selects a medal that can be used and a medal that is not usable according to the medal diameter, and the medal inserted from the medal slot 104 is incompatible with the slot machine 100. If it is a medal, it is selected by the medal identification mechanism 200 and discharged to the medal discharge path 117 located below it.

  On the other hand, if the medal inserted from the medal insertion slot 104 is a medal that matches the slot machine 100, the medal selected by the medal identification mechanism 200 is discharged to the medal supply path 116. The medal replenishment path 116 extends from the front door 103 to the back (the back side of the main body 102), and when the front door 103 is in a closed state, its tip is positioned above the auxiliary tank 112a. It is configured. As a result, medals suitable for the slot machine 100 are guided by the medal identification mechanism 200 and the medal replenishment path 116, replenished to the auxiliary tank 112a, and stored in the tank.

  In addition, the medal identification mechanism 200 acquires a sensor signal necessary for authenticity determination and counting of the medal inserted from the medal insertion slot 104 and transmits the signal to the control device 120. The control device 120 performs authenticity determination and counting of medals based on the sensor signal from the medal identification mechanism 200. Such sensor signal acquisition will be described later together with the configuration of the medal identification mechanism 200.

  Here, the state of the game by the slot machine 100 will be briefly described. When a player inserts a medal into the medal insertion slot 104 of the front door 103, the medal passes through a medal path described later that guides a medal from the medal insertion slot 104 to the medal identification mechanism 200 and reaches the medal identification mechanism 200. The medal identification mechanism 200 distributes and sends medals to the hopper device 112 if the medal passing through the medal path is appropriate as described above, and discharges the medal to the outside through the medal discharge path 117 if not appropriate. . Along with this distribution, the medal identification mechanism 200 outputs a sensor signal, which will be described later, to the control device 120. Therefore, the control device 120 determines whether the medal is true or not. Become. If it is not a genuine medal, the control device 120 notifies the fact by an indicator lamp of the front door 103 or the like.

  When the game can be started, the player operates the start lever 105 of the front door 103. If it does so, since the control apparatus 120 will rotate the rotating drum 111, respectively, a player will press the stop button 106 corresponding to the rotating drum 111. FIG. In response to the pressing, the control device 120 stops the rotating drum 111. Then, the prize medal is discharged to the medal tray 115 based on the coincidence state of the diagonally vertical and horizontal patterns of the three rotating drums 111 that are stopped.

  Next, the medal identification mechanism 200 will be described. FIG. 3 is an explanatory diagram showing a schematic configuration of the medal identification mechanism 200. As illustrated, the medal identification mechanism 200 includes a medal path 202 that guides the inserted medal M. The medal path 202 is formed so that medals pass in one row, and the medal M is received from the medal insertion path 104 of the front door 103 through the medal replenishment path 116 (see FIG. 2) and passed downstream. The medal path 202 includes a main path 203 having a trajectory curved from the upper side of the apparatus to the right side of the apparatus and a discharge path 204 of a trajectory extending straight downward from the upper side of the apparatus. The main path 203 passes the medal M along the curved trajectory and sends the medal to the medal supply path 116 of FIG. 2 described above. The discharge path 204 sends the medal M to the medal discharge path 117 by path switching by driving a path switching piece 205 installed at a path branching location of the main path 203. The passage switching piece 205 projects into the medal route 202 by a solenoid (not shown), thereby switching the route. Note that such path switching with solenoid driving is performed according to the result of the above-described medal distribution based on the diameter, and is also performed by a return switch operation by the player when a medal is jammed. In each of the above-described medal paths, the medal installation location is a ridge, and the medal M is conveyed so as to roll while touching the top of the ridge.

  The medal identification mechanism 200 includes a medal detection unit 210 in the middle of the main path 203. FIG. 4 is an explanatory diagram schematically showing the appearance of the medal detection unit 210, and FIG. 5 is an explanatory diagram showing the medal detection unit 210 in a broken view. As shown in these drawings, the medal detection unit 210 includes a body 212 and is fixed to the casing of the medal identification mechanism 200 with screws. The medal detection unit 210 includes an optical path forming body 214 protruding from the body 212 on the front side of the medal M passing through the main path 203 (the front side in the drawing of FIG. 3), and a light emitting diode is formed on the base of the forming body. It has three light emission parts 216a-216c.

  Light (emitted light) emitted from each of the light emitting units 216a to 216c travels through the small-diameter through hole 217 on the front side of each light emitting unit as an optical path, and is reflected by the reflecting surface 218 at the tip of the optical path forming body 214. Since the reflecting surface 218 is formed so as to be inclined as shown in the drawing, the reflected light from the reflecting surface 218 travels obliquely toward the body 212 with the locus indicated by the symbol A in the drawing as the optical axis. That is, the medal detection unit 210 emits light from a direction that obliquely intersects the medal surface with respect to the medal M passing through the main path 203.

  The medal detection unit 210 includes light receiving units 220a to 220c made of photosensors in the body 212, and these light receiving units are arranged corresponding to the light emitting units described above. A position where the reflecting surface 218 is located on the distal end side of the optical path forming body 214, the light receiving portions 220a to 220c are located on the body 212 side, and the medal M is located between the optical path forming body 214 and the light receiving portions 220a to 220c. From the relationship, each of the light receiving units 220a to 220c receives light from a direction obliquely intersecting the medal M passing through the main path 203, and outputs a light reception signal corresponding to the received light amount. From such a positional relationship between the light emitting units 216a to 216c and the light receiving units 220a to 220c, the light emitting units 216a to 216c and the light receiving units 220a to 220c emit light to the medal M passing through the main path 203 and detect it. The detection unit inclines the optical axis of the light emitted from the light emitting units 216a to 216c and received by the light receiving units 220a to 220c with respect to the medal M.

  The medal detection unit 210 forms an optical system with the light emitting units 216a to 216c, the reflection surface 218, and the light receiving units 220a to 220c as a pair, and the optical system is incorporated in the body 212 in three pairs. FIG. 6 is an explanatory view schematically showing the state of three pairs of optical systems having a light emitting part and a light receiving part. In the following description, in order to distinguish three pairs of the above optical systems, the light emitting unit and the light receiving unit of each optical system are represented by a first light emitting unit 216a, a second light emitting unit 216b, and a third light emitting unit 216c. , The first light receiving unit 220a, the second light receiving unit 220b, and the third light receiving unit 220c.

  As schematically shown in FIG. 6, it has an optical system (first optical system) having a first light emitting part 216a and a first light receiving part 220a, and a second light emitting part 216b and a second light receiving part 220b. The optical system (second optical system) and the optical system (third optical system) having the third light emitting unit 216c and the third light receiving unit 220c are at a predetermined interval, that is, the medal detection of the light emitting unit / light receiving unit described above. It is separated by an interval for incorporation into the section 210.

  In this embodiment, two or more of the three optical systems are used as effective optical systems effective for detecting a detection target, and used for detection of medals M, light emitting foreign matter, and liquid crystal panel foreign matter. At this time, in the effective optical system, light is emitted from each light emitting unit included in the optical system, and light is not emitted from the light emitting unit in optical systems other than the effective optical system among the three optical systems. did. That is, among the three light receiving signals output from the light receiving units 220a to 220c, the light receiving signals for two or more effective optical systems are used for detection of the medal M. By doing so, as will be described later, a light reception signal from a light receiving unit of an optical system other than the effective optical system can be used for foreign object detection.

  In this embodiment, since the first to third optical systems are provided, the combination of two or more effective optical systems that can be set is the first optical system and the second optical system are the first effective optical systems. The set, the second optical system and the third optical system are a second set of effective optical systems, and the first optical system and the third optical system are a third set of effective optical systems. These combinations are set at a predetermined timing as will be described later. In this case, a combination (all optical system set) in which all of the first to third optical systems are set as effective optical systems can also be adopted, but in this example, this all optical system set was not adopted. This point will be described later. When the number of effective optical systems is increased, the number of optical systems included in the medal detection unit 210 may be four or more. For example, when four optical systems are used, two of these optical systems are used as effective optical systems. There are six combinations, and four combinations with three optical systems as effective optical systems.

  As the medal M passes through the main path 203, the medal M is first applied to the optical axis of the first optical system, and then applied to the respective optical axes in the order of the second optical system and the third optical system. Therefore, in this embodiment in which light is emitted by each optical system, a light reception signal associated with the passage of the medal is obtained in the order of the first light receiving unit 220a, the second light receiving unit 220b, and the third light receiving unit 220c. Since the interval of the optical system along the path of the medal M passing through the main path 203 is predetermined and the passing speed of the medal M in the main path 203 is also known in advance, the first to third The presence / absence or authenticity of the medal M passing through the main path 203 is determined depending on the light reception state in the optical system. Such processing will be described later.

  Here, the electrical configuration of the slot machine 100 of the present embodiment will be described focusing on the configuration related to the present invention. FIG. 7 is a block diagram showing an outline of the electrical configuration of the slot machine 100.

  The control device 120 includes a control unit 121 that controls the overall apparatus. This control unit 121 is mainly configured by a CPU that executes logical operations, and cooperates with a ROM that stores game programs and the like, a RAM that temporarily stores data, and the like, to detect medals, determine medal authenticity, Medal counting, display device control, rotation control of the rotating drum 111, and the like are performed. The control unit 121 includes a medal number counter in addition to the CPU, and includes a reset switch 122, a start lever 105, a first light emitting unit 216a, a second light emitting unit 216b, a third light emitting unit 216c, a first light receiving unit 220a, and a second light receiving unit. Connected to the light receiving unit 220b, the third light receiving unit 220c, the optical system setting switch 225, the various sensor / switch group 123, the display device, the rotating cylinder, and other control target device group 124, the light emission control of each light emitting unit described above. And control various devices. The control unit 121 configures an optical system automatic setting unit 125, a detection unit 126, and a game continuation determination unit 127 in cooperation with the CPU and ROM programs.

  Here, the light emission control of the light emitting unit 216 performed by the control unit 121 will be briefly described. In this embodiment, the light emitting unit 216 is not simply controlled to emit light, but a pulsed light emission signal is output to the light emitting unit 216 of each optical system, and light is emitted from the light emitting unit 216 of each optical system in a pulsed manner. Then, the medal M passing through the main path 203 is irradiated with this pulsed light. The light receiving unit 220 of each optical system receives pulsed light and outputs a light reception signal in a pulse shape. Since the light receiving state changes due to the light blocking by the medal M accompanying the passage of the medal M, the control unit 121 receives a pulse-shaped light receiving signal whose light receiving level changes as the medal M passes. Input from the light receiving unit 220.

  The optical system automatic setting unit 125 sets two or more effective optical systems at a predetermined timing, for example, a power-on timing to the slot machine 100 and a periodic timing every predetermined time, that is, the above-described first to third. Set any effective optical system combination in the set. The cycle timing can be a fixed timing such as 10:00, 11:00, etc., and is shorter than the timing every 15 minutes or the time normally required for a player to play a game (about 2 to 3 minutes). The timing for each time (for example, every 1 minute, every 30 seconds) and the timing at which the game situation has changed to a jackpot can be adopted. On the other hand, the optical system setting switch 225 is for a hall attendant to manually set two or more effective optical systems, and the control unit 121 uses the switch operation as a timing to perform the above-described first operation. A combination of any one of the first to third sets of effective optical systems is set.

  The detection unit 126 synchronizes the output status of the received light signal from the light receiving unit 220 of the set effective optical system and the pulse signal received from the light emitting unit 216 of the effective optical system and the pulsed light reception signal from the light receiving unit 220. The authenticity of the medal M is determined based on the situation and the like. The game continuation determination unit 127 determines whether to continue the game in the slot machine 100 and stop the game according to the result of the true / false determination. Specifically, when it is determined that the medal M is a genuine medal, the game of the slot machine 100 is permitted to continue thereafter, so that the player plays a game with the operation of the start lever 105 and the stop button 106. be able to. On the other hand, if the detection target is a light emitting foreign object or a liquid crystal panel foreign object that simulates the medal M, various devices are controlled to stop the game. For example, the operation of the start lever 105 and the stop button 106 is invalidated so that the game cannot be played, and various display devices, speakers, and the like are notified that an unauthentic medal M has been detected.

  Next, regarding processing performed by the control device 120 (specifically, the control unit 121) of the slot machine 100 of the present embodiment, true medal detection, foreign object detection imitating a medal, light emission by the light emitting unit 216, The state of light reception by the light receiving unit 220 will be described together. FIG. 8 is a flowchart showing the contents of the effective optical system combination setting process, and FIG. 9 is a flowchart showing the contents of the medal M and foreign object detection process.

  The setting process shown in FIG. 8 is repeatedly executed every predetermined time, and the control unit 121 first determines whether or not it is a setting timing (step S100). That is, as described above, if the optical system automatic setting unit 125 determines that the current timing is the periodic timing for each predetermined time in the setting process of this time, the control unit 121 sets the first to third sets described above. One of the effective optical system combinations is set (reset) (step S110). On the other hand, if it is not the above timing, this routine is terminated without performing any processing.

  When setting the combination of the effective optical systems described above, there is a method of selecting the first to third combinations at random according to, for example, a random number generated by a random number generator. Alternatively, a method of switching and setting the first to third combinations according to a predetermined rule can be taken.

  The setting process of FIG. 8 is during operation of the slot machine 100. At the power-on timing of the slot machine 100, the optical system automatic setting unit 125 of the control unit 121 performs a combination of effective optical systems in the same manner as in step S110. Is automatically set. Further, at the operation timing of the optical system setting switch 225 by the hall attendant, the control unit 121 receives the switch operation and sets a combination of effective optical systems in the same manner as in step S110.

  Even in the detection process shown in FIG. 9, the control unit 121 is repeatedly executed at predetermined time intervals, and the control unit 121 inputs and monitors the light reception signals from the light reception units 220a to 220c of the first to third optical systems (step S200). ). Next, from this monitoring result, it is determined whether or not there is a light reception signal from the light receiving unit of the optical system other than the effective optical system (step S210), and if there is a light reception signal from the light receiving unit of the optical system other than the effective optical system, If a luminescent foreign object has been detected, the process proceeds to step S215, where game stop processing and foreign object detection notification are performed. The game stop process includes making the operation of the start lever 105 and the stop button 106 invalid so that the game cannot be played. As the foreign object detection notification, the non-authentic medal M is displayed on various display devices or speakers. Is detected by voice or display.

  An example of such foreign object detection will be described. Now, for example, it is assumed that the first optical system and the second optical system are effective optical systems in the first set combination, and the third optical system is an optical system other than the effective optical system. In this case, in the first optical system and the second optical system of the effective optical system, the first light emitting unit 216a and the second light emitting unit 216b emit light, and in each optical system, the first light receiving unit 220a and the second light receiving unit. Light is received at 220b. In the third optical system other than the effective optical system, since the third light emitting unit 216c does not emit light, the corresponding third light receiving unit 220c does not emit a light reception signal or emits a light reception signal of the minimum level (= zero level).

  FIG. 10 is an explanatory diagram schematically showing how the luminescent foreign matter is detected. Since the optical system of the present embodiment is a transmissive type, the light-emitting foreign matter is formed of a non-light-transmitting member on one surface in order to block the light emitted from the light-emitting portion 216, and the other surface, that is, the light-receiving portion 220 side. Emits light on the surface. As shown in FIG. 10 (a), when the light-emitting foreign matter has only one light-emitting portion DP shown in the figure, the light-emitting foreign matter is caused by the light emission from the light-emitting portion DP and the first to third totals. The light is received by the light receiving portions 220a to 220c of all the optical systems. Then, even in the third optical system other than the effective optical system, light is received by the third light receiving unit 220c, but the genuine medal M is directed from the first optical system side to the third optical system. In the third optical system other than the effective optical system, the third light emitting unit 216c does not emit light so that the third light receiving unit 220c does not receive the light. The same applies to combinations of effective optical systems in the second set and the third set. That is, by not adopting the entire optical system set in which all the optical systems are effective optical systems as the effective optical system combination, it is possible to immediately detect the light emitting foreign matter as shown in FIG. It should be noted that a combination of all optical systems in which all the optical systems are effective optical systems can be set as one of the effective optical system combinations as in the first to third sets. In this case, step S210 may be omitted, and the light emitting foreign matter may be detected in steps S220 and S230 described later.

  Further, as shown in FIG. 10 (b), the light emitting foreign substance is provided with three light emitting points DP1 to DP3 corresponding to each optical system, and controls the light emission at each light emitting point to simulate the passing of the medal. If this light emitting foreign material emits light at the light emitting location DP3, the light receiving by the third light receiving unit 220c of the third optical system in the same manner as the light emitting foreign material of FIG. A negative determination is made in step S210, and foreign object detection / notification is performed in step S215. The case where the light emitting foreign matter controls the light emission point DP1 and the light emission point DP2 will be described later.

  On the other hand, if it is determined in step S210 that there is no light reception signal from the light receiving unit of the optical system other than the effective optical system, the medal M passes through each effective optical system in the current effective optical system setting combination (for example, the first set). It is determined whether or not a received light signal has been input (step S220). This determination is made as follows.

  When the genuine medal M passes through the main path 203, the first optical system and the second optical system can be combined with the upstream optical system of the effective optical system and the first set of effective optical systems. In order, the medal M is applied to the optical axis of each optical system. Therefore, in the present embodiment in which light is emitted by the effective optical system, if the combination of the first set of effective optical systems is used, the control unit 121 causes the first light receiving unit 220a and the second light receiving unit 220b to pass by the passage of the medal M. From these light receiving sections, light reception signals accompanying medal passage are input.

  By the way, as described above, the control device 120 includes the light emitting unit of the effective optical system (the first light emitting unit 216a and the second light emitting unit 216b of the second optical system in the first set of effective optical systems). Since light emission is controlled in a pulsed manner according to a predetermined cycle, the light receiving unit of each optical system periodically outputs a pulsed light receiving signal (ON signal) according to the pulse of the light emitting unit when there is no medal passage. On the other hand, when the medal M is inserted, the light of the first light emitting unit 216a of the first optical system is blocked with the passage of the medal, and then the light of the second light emitting unit 216b of the second optical system is blocked. If the distance between the first optical system and the second optical system is larger than the medal diameter, after the first light receiving unit 220a of the first optical system has not received the light of each pulsed light emission of the first light emitting unit 216a, The first light emitting unit 216a receives light (outputs a pulsed ON signal), and the second light receiving unit 220b of the second optical system has a period of not receiving the light of each pulsed light emission of the second light emitting unit 216b. The second light emitting unit 216b receives light (pulsed ON signal output).

  On the other hand, the distance between the first optical system and the second optical system is often smaller than the medal diameter due to the shortening of the path or the like. In such a case, the pulsed light from the light emitting unit is blocked in the order of the first optical system and the second optical system as the medal M passes, but after the light is blocked simultaneously by both optical systems, The light from the light emitting unit is received by the light receiving unit again in the order of the first optical system and the second optical system. Therefore, the output of the pulsed light reception signal at the light receiving unit in each optical system is first caused by the non-light reception (OFF signal) period at the first light receiving unit 220a in the first optical system as the medal passes. Next, during the period of no light reception (OFF signal) in both optical systems, the first light receiving unit 220a in the first optical system receives light (pulsed ON signal output) and the second light receiving unit in the second optical system. In 220b, the period of no light reception (OFF signal) and the period of light reception (pulsed ON signal output) in both optical systems are continuous.

  The light reception state (pulse-shaped light reception signal output state) of the light receiving unit 220 as the medal M passes through the effective optical system described above has a predetermined interval between the first and second optical systems. Since the passing speed of the medal M at 203 is also known in advance, it is determined by the combination of effective optical systems. Based on the input / monitoring of the received light signal for the effective optical system monitored in step S200, the control unit 121 determines that the light reception status from the light receiving unit 220 of the set effective optical system is the genuine medal M. It is determined whether or not the path 203 has been passed.

  In step S220, an affirmative determination is made when a genuine medal M is inserted, and the process proceeds to step S230 described later. However, the light emitting foreign material shown in FIG. 10 is as follows. In addition, since the light-emitting foreign material which has only the single light emission location DP is detected as a foreign material by step S210, the following description demonstrates the light emission foreign material which has several light emission locations.

  Since step S220 is after the affirmative determination in step S210 before that, for example, in the case of a combination of the first set of effective optical systems, there was no light reception by the third light receiving unit 220c of the third optical system. That is, the light emitting foreign matter controls the light emission at the light emission point DP1 and the light emission point DP2.

  Now, it is assumed that the light emitting foreign matter is causing the light emitting part DP1 and the light emitting part DP2 to emit light simultaneously. Then, the light reception state from the first light receiving unit 220a of the first optical system and the second light receiving unit 220b of the second optical system is clearly different from the case where the genuine medal M passes through the main path 203. Therefore, in step S220, a negative determination is made that the light emitting foreign object is detected, and in step S215, the game is stopped and the foreign object detection is notified.

  In the case where the light emitting foreign matter controls the light emission spot DP1 and the light emission spot DP2 by controlling the emission of the medal, from the first light receiving part 220a of the first optical system and the second light receiving part 220b of the second optical system by this light emission control. If the received light state does not coincide with the received light state associated with the passage of the genuine medal M, a negative determination is made in step S220 that the light emitting foreign object is detected, and in step S215, the game is stopped and the foreign object detection is notified. If both the above-mentioned light receiving states coincide with each other by the light emission control of the light emitting spot DP1 and the light emitting spot DP2 in the light emitting foreign matter, an affirmative determination is made in step S220, but this light emitting foreign matter detection will be described later.

  In step S230, the output status of the received light signal from the light receiving unit 220 of the set effective optical system, and the synchronization status of the pulse signal output to the light emitting unit 216 of the effective optical system and the pulsed light received signal from the light receiving unit 220 are set. Is determined to be associated with the passage of the medal M. That is, as described above, the light emitting unit 216 of the effective optical system emits light in a pulse shape based on the pulsed light emission signal, and the light receiving unit 220 has the detection target on the optical axis in the optical system. Otherwise, a pulsed light reception signal synchronized with the light emission signal is output, and a light reception signal whose light reception level has shifted to the minimum level when the detection target is applied to the optical axis is output.

  That is, when the genuine medal M passes through the main path 203, the medal M is applied to the optical axis that the light emitted from the light emitting unit 216 is reflected by the reflecting surface 218 and reaches the light receiving unit 220. Since the medal M is usually made of metal, the medal M blocks light emitted from the light emitting unit 216 (reflected light from the reflecting surface 218). As a result, the light receiving unit 220 does not receive the light that could be received until then, which means that the control device 120 receives a light reception signal (minimum level signal = zero level signal) corresponding to no light reception. When the medal M further passes through the main path 203 and leaves the optical axis, the light receiving unit 220 directly receives the light emitted from the light emitting unit 216 (the reflected light from the reflection surface 218), and a light reception signal corresponding to the received light amount. Is output to the control device 120. As described above, the light reception signal changes (increases) from the minimum level as the medal M passes through the main path 203. Such transition of the received light signal level is manifested in each of the pulsed received light signals that have received the light of each pulse since the light emission is pulsed.

  The control unit 121 generates a light reception signal (sensor output) based on the transition of the amount of received light accompanying the passage of the medal as an effective optical system, for example, the first light receiving unit 220a of the first optical system and the second if the first set. It inputs from the 2nd light-receiving part 220b of an optical system. Then, the control unit 121 sequentially receives such a signal input from the first optical system and the second optical system, which are current effective optical systems, thereby detecting the passage of the medal M and performing medal counting, as well as the light emission signal. If the synchronization state of the received light signal and the transition of the received light signal level are suitable for passing the genuine medal M through the sensor, an affirmative determination is made in step S230, and continuation of the game is permitted as described above (step S240). This routine is terminated.

  If the light emitting foreign matter shown in FIG. 10B controls the light emission at the timing associated with the passage of the medal M at the light emission point DP1 and the light emission point DP2, each of the light emission point DP1 and the light emission point DP2 is authentic. If the synchronization state of the light emission signal and the light reception signal in the effective optical system associated with the passage of the medal M is reproduced, and the signal level transition of the light reception signal associated with the passage of the genuine medal M does not coincide with the step, In S230, a negative determination is made as the detection of the luminescent foreign object, and the game is stopped and the foreign object detection is notified in step S215. The light emission control status of the light emitting part DP1 and the light emitting part DP2 in the light emitting foreign matter coincides with the synchronization state of the light emission signal and the light reception signal accompanying the passage of the genuine medal M, and the signal level transition of the light reception signal accompanying the passage of the genuine medal M. If so, an affirmative determination is made in step S230, but detection of the luminescent foreign matter in this case will be described later.

  As described above, in the slot machine 100 of the present embodiment having the above-described configuration, two of the three optical systems are effective optical systems used for detecting the medal M, and the combination is switched at a predetermined timing. Set (see FIG. 8). Then, according to the output state of the light reception signal of the light receiving unit 220 in the set effective optical system and the synchronization state of the light emission signal and the light reception signal (steps S210 to 230), the detection of the medal M and the detection of the light emitting foreign matter are performed. According to the result, permission to continue the game and stop / foreign object detection notification are performed. Therefore, there are the following advantages.

  First, with respect to the light emitting foreign matter having a single light emitting point DP shown in FIG. 10A, the foreign matter detection is easily performed by the light reception signal of the light receiving unit 220 in the optical system other than the effective optical system. For the light-emitting foreign matter having a plurality of light-emitting points DP1 to DP3 shown in FIG. 10B, light emission at the light-emitting point DP3 corresponding to an optical system other than the effective optical system and the light-receiving signal of the light-receiving unit 220 in the optical system Thus, the foreign object detection is easily performed. When the passing of the medal M is simulated with a light emitting foreign matter having a plurality of light emitting locations DP1 to DP3 shown in FIG. 10B, the light emission status of the light emitting locations DP1 to DP3 is an optical system included in the medal detection unit 210. The light emission unit 216 of the light emission unit 216, the synchronization of the light emission signal and the light reception signal, and the light reception signal level of the light reception unit 220 are externally adjusted to imitate the pulse light emission of the light emission unit 216 of the medal detection unit 210. It is done. If the light emission statuses of the light emission locations DP1 to DP3 thus adjusted match the light emission portions 216 of the two effective optical systems in the medal detection unit 210, the light emitting foreign matter having a plurality of light emission locations DP1 to DP3 is obtained. The medal passage of the main route 203 can be falsified. This is equivalent to being affirmatively determined in step S220 or step S230 while being a luminescent foreign object.

  However, in the present embodiment, as described above, the combination of the effective optical systems changes each time by resetting at a predetermined timing. It is difficult to adjust the light emission status of the light emitting portions DP1 to DP3 of the light emitting foreign matter so that the light receiving part 220 of the effective optical system of the combination is output. Therefore, the output state of the light reception signal at the light receiving unit 220 in the two or more effective optical systems when the genuine medal M passes through the main path 203, and the case where the light emitting foreign matter is inserted in place of the medal M are two. The output state of the received light signal at the light receiving unit 220 in one or more effective optical systems hardly coincides, and a negative determination is made in step S220 or step S230. Even if the light emission statuses of the light emission points DP1 to DP3 coincide with those associated with the passage of the medal M once corresponding to the combination of the effective optical systems, the coincidence state continues by resetting the combination of the effective optical systems. In the subsequent game period, a negative determination is made in step S220 or step S230. For this reason, according to the slot machine 100 of the present embodiment, the reliability of foreign object detection can be further increased, and the continuation permission of the game machine and the determination of the game stop according to the detection result of the foreign object detection are also possible. Reliability can be increased.

  In this embodiment, the effective optical system is set at a specific time timing such as a power-on timing to the slot machine 100 or a fixed timing, as well as an operation timing of the optical system setting switch 225, every 15 minutes. The game is executed even when the timing, the timing for each time shorter than the time required for one game by the player (about 2 to 3 minutes), or the timing when the game situation has changed to a big hit. Therefore, since so-called effective optical system setting can be performed, the setting of the effective optical system can be changed every time when the use of a light emitting foreign material is suspected, and the reliability of foreign object detection can be further improved.

  In the present embodiment, in addition to resetting the combination of effective optical systems, the synchronization of the light emission signal and the light reception signal in the set effective optical system and the situation of the light reception signal level are also used for detection of the medal M. Therefore, it is more difficult to control the light emission locations DP1 to DP3 so that the signal synchronization and the signal level coincide with each other. Therefore, also from this point, the reliability of foreign object detection can be further enhanced.

  In addition, when a pulsed light emission signal is output to the light emitting unit 216 of the effective optical system and pulsed light is emitted from the light emitting unit, the light emitting unit 216 of each optical system is schematically shown in FIG. It is also possible to give a difference in the pulse amplitude to the light emission signal output to. Specifically, the pulse amplitude is decreased in the order of the first optical system to the third optical system. By so doing, the amount of emitted light can be different for each optical system, so the received light signal level at the light receiving unit 220 for each optical system (effective optical system) is also different. Further, in order to simulate the passage of the medal M with the light emitting foreign matter, it is necessary to control the light emission locations DP1 to DP3 with different amounts of light for each light emission location, but since such control is more difficult, the reliability of foreign matter detection Is even higher.

  Furthermore, as described above, when giving a difference in the pulse amplitude for each optical system, the pulse amplitude for each optical system can be set for each setting of the effective optical system. For example, if the first optical system is set as one of the effective optical systems at a certain timing, the pulse amplitude of the light emission signal is set small, and the first optical system is one of the effective optical systems at other timings. When set as one, the pulse amplitude of the light emission signal is set large. In this way, since the light emission state (light emission amount) can be set in accordance with the setting of the effective optical system, it becomes more difficult to control the light emission at the light emission point adapted to such setting change, and the reliability of foreign object detection is further increased. .

  Even if it is a liquid crystal panel foreign body that moves the non-translucent part by switching between translucent and non-translucent, the movement status of the non-translucent part is combined with an effective optical system that changes the combination at a predetermined timing Since it is difficult to carry out the process accordingly, it is a matter of course that liquid crystal panel foreign matter can be detected with high reliability as well as light emitting foreign matter.

  Next, a modified example will be described. FIG. 11 is an explanatory diagram schematically showing the configuration of an optical system in a modification. As shown in the figure, this modification has a point in which the color of light emitted for each optical system is changed, and a light receiving unit for light emitted by the optical system and a light receiving unit for other colors for each optical system. There is a feature.

  As shown in the drawing, in the slot machine 100 of this modification, the first optical system emits red light by the red filter Rf in the optical path of the first light emitting unit 216a. Similarly, in the second optical system, green color is emitted by the green filter Gf, and in the third optical system, blue light is emitted by the blue filter Bf. The first optical system includes a red filter 220Rf, a light receiving unit 220aR for receiving red light, a green filter 220Gf, and a light receiving unit 220aG for receiving green light, and the second optical system includes a green light receiving unit 220aG. The third optical system includes a filter 220Gf, a light receiving unit 220bG for receiving green light, a blue filter 220Bf, and a light receiving unit 220bB for receiving blue light, and the third optical system receives light for receiving the blue filter 220Bf and blue light. Part 220cB, a red filter 220Rf, and a light receiving part 220cR for receiving red light.

  And in this modification, since the combination of two effective optical systems is set at a predetermined timing in the same manner as in the above-described embodiment, among the first to third optical systems, the effective optical system Each time the combination is set, the combination of the set colors (effective colors) of the emitted light of the effective optical system changes. Further, if light of a color other than the effective color emitted by the effective optical system is emitted, for example, if white light or green light is emitted in the first optical system, the light reception of the first optical system by the filter 220Gf. Although the light is received by the unit 220aG, if the first optical system is an effective optical system, only red light, which is an effective color, is emitted, and therefore light reception by the light receiving unit 220aG usually does not occur.

  A description will be given of how the light emitting foreign matter is detected in the modified example having the above-described configuration. In many cases, the light emitting foreign matter emits light of a single color (for example, white light) from each light emitting portion, regardless of the number of light emitting portions as shown in FIGS. Therefore, now, when the first optical system and the second optical system are effective optical systems, when the luminescent foreign matter is applied to these optical systems, the white light emitted by the luminescent foreign matter is The filter 220Rf and the filter 220Gf receive light not only in the light receiving part 220aR for receiving red light but also in the light receiving part 220aG for receiving green light. The same applies to the second optical system. Therefore, the light receiving state of the light receiving unit 220aR and the light receiving unit 220aG in each effective optical system by the genuine medal M is significantly different from the light receiving state in these light receiving units by the light emitting foreign matter. In addition, the combination of two or more effective optical systems is not uniform and changes depending on the setting, so that a combination of two or more light emitting points DP1 to DP3 in a light emitting foreign material and a combination of two or more effective optical systems. Is rarely the same. As a result, even in the modified example of the above configuration, it is possible to detect the light emitting foreign matter with high reliability.

  As mentioned above, although the Example of this invention was described, this invention is not restricted to above-described embodiment, In the range which does not deviate from the summary, it is possible to implement in various aspects. For example, in the above-described embodiments and modifications, the detection target object such as the medal M, the light emission foreign matter, and the liquid crystal panel foreign matter is obtained by reflecting the emission light DL of the light emitting unit 216 on the reflection surface 218 and using the reflected light as the emission light DL. However, it is also possible to adopt a transmissive type in which the light emitting unit 216 itself is disposed at the installation location of the reflection surface 218 and the detection target is directly irradiated with the emitted light DL of the light emitting unit 216. Not limited to this, the light emitted from the light emitting unit 216 may be irradiated to the medal M, the light emitting foreign material, or the liquid crystal panel foreign material and reflected by these surfaces, and the reflected light may be received by the light receiving unit 220. it can.

  Further, when the light emission of the light emitting unit 216 in each optical system is changed to a pulse shape, the pulse amplitude can be changed for each optical system as the characteristic of the pulse signal as schematically shown in FIG. The period and the pulse width can be changed for each optical system. Even if it does in this way, if it explains in accordance with a present Example and the output state of the light reception signal for every optical system, the light emission control of the light emission location of a light-emitting foreign material and a liquid crystal panel will be set to the output state of the light reception signal for every set effective optical system It is difficult to match the movement control of the non-translucent part in the foreign matter, which is useful for improving the reliability of foreign matter detection.

  Further, in the modification shown in FIG. 11, the light emitted from the light emitting unit 216 for each optical system is made to have a specific color light by a filter. However, the RGB light source is a light emitting unit for each optical system. The color of the light from the light emitting unit can be set by adjusting the output of each light source. The color of light in the combined effective optical system can be changed and set together with the setting of the effective optical system. In this way, even if the configuration is such that the light emitting foreign matter can change the color of light at each of the light emitting points DP1 to DP3, each light emitting point can be adapted to the combination setting of the effective optical system and the light color setting. It is difficult to change the color of light, and it is possible to detect a luminescent foreign object with high reliability.

  Further, the slot machine for playing using the medal M has been described as an example, but the present invention is a gaming machine other than the slot machine and uses the medal M, in addition to the medal detection device and the medal path. It can also be applied as a medal detection method for passing. In addition, a magnetic sensor with a built-in magnet can be used.

  Further, the optical system in the medal detection unit 210 may be four or more optical systems. In this case, the effective optical system can be set to either a combination of two optical systems or a combination of three optical systems. . Therefore, in such a case, the number of effective optical systems can also be set at the timing described above, which makes it more difficult to control the emission of foreign matter according to the number of effective optical systems, and to ensure the reliability of foreign matter detection. Sexuality increases.
