Description

  The present invention is a game medium regular detection means for detecting the presence / absence of a game medium at a plurality of stages installed in stages according to the storage amount of the game medium in a storage tank for storing a game medium used in a gaming machine. Based on the game medium storage amount detection device for detecting the storage amount of the game medium in the storage tank and the signal transmitted from the game medium storage amount detection device, the storage amount of the game medium in the storage tank is determined. The present invention relates to a game medium storage amount display device for display.

  2. Description of the Related Art Conventionally, a plurality of gaming machine islands represented by pachinko islands installed in a game arcade are provided with a game medium (pachinko ball) transfer system such as an island exchange method or an independent island method. In these pachinko ball transfer systems, a ball storage amount detection device is usually used by using the detection results of a ball amount sensor (game medium regular detection means) provided in a pachinko ball storage tank installed in the pachinko island platform. Is used to calculate the amount of pachinko balls in the storage tank, and various controls are performed based on the calculated results. For example, in an island exchange type transfer system, a ball amount sensor (hereinafter referred to as a lower limit sensor) that detects a lower limit of an allowable range in which pachinko balls can be stored due to a lack of pachinko balls on the island is turned on. The pachinko balls are transferred from the neighboring island by the detection signal of the lower limit sensor. On the other hand, a ball amount sensor (hereinafter referred to as an upper limit sensor) that detects an upper limit of an allowable range in which the pachinko balls can be stored due to an excessive amount of pachinko balls on its own island is turned ON, Pachinko balls are transferred to the neighboring island. In this way, the pachinko balls in each pachinko island platform are averaged by transferring the pachinko balls between each pachinko island platform based on the detection signal of the ball sensor provided in the storage tank. (For example, Patent Document 1).

  In addition, in the independent island type transfer system, the lower limit sensor of the pachinko ball amount is turned ON due to the lack of the pachinko ball amount of the own island, and the pachinko in the ball return device installed on the own island by the detection signal of this lower limit sensor. The ball return port (hereinafter referred to as the ball return port) is opened and the ball return port in the ball return device installed on the neighboring island is closed. On the other hand, when the pachinko ball amount on the own island becomes excessive, the upper limit sensor of the pachinko ball amount is turned ON, and the ball return port in the ball return device installed on the own island is closed by the detection signal of the upper island, Open the ball return port on the ball return device installed on the island. In this way, based on the detection signal of the ball quantity sensor provided in the storage tank, the pachinko ball quantity in each pachinko island stand can be changed by making the pachinko ball returnable or non-returnable to the pachinko island stand. Averaging is performed (for example, Patent Document 2).

Needless to say, the ball quantity sensor provided in the storage tank is also used in, for example, a ball storage quantity display device that displays the pachinko ball quantity in the storage tank, in addition to the control (transfer system) described above. .

  As described above, the ball quantity sensor of the storage tank is indispensable in the pachinko ball transfer system in the pachinko island platform. For this reason, if the ball quantity sensor becomes abnormal, the transfer system may not function normally, which may hinder the operation of the game hall. Note that the cause of the abnormality of the ball quantity sensor is, for example, an impact caused by a pachinko ball colliding with the ball quantity sensor itself, a signal line connecting the control board for controlling the ball quantity sensor and the ball quantity sensor. There is an influence of static electricity, a change of the ball quantity sensor with time, etc., and it is considered that there is no ball quantity sensor that can solve all these causes at the current technical level.

  Thus, in the conventional pachinko island platform represented by the above-mentioned patent document 1 and patent document 2, every time the ball amount sensor malfunctions due to the above-mentioned causes or the like, the wall surface of the lower part of the pachinko island platform (common name, waist plate) The ball quantity sensor was replaced. At this time, when a large amount of pachinko balls are stored in the storage tank, the replacement operation is performed after the pachinko balls are removed from the storage tank in order to facilitate the replacement of the ball amount sensor.

  As described above, when the ball quantity sensor has an abnormality, it is necessary to replace the ball quantity sensor which takes time, but this work does not hinder the game of the player. In this way, it is usually done after the game hall is closed or on a holiday, avoiding the business, so even if the ball quantity sensor malfunctions during the game hall business, the ball quantity sensor We must continue to operate in an abnormal state. This may interfere with the operation of the amusement hall.

  Therefore, the present applicant causes the game medium storage amount detection device applied to the conventional pachinko island platform represented by Patent Document 1 and Patent Document 2 described above to operate when the normal sensor and the normal sensor are abnormal. An attempt was made to apply a game medium storage amount detection device using a ball amount sensor composed of a spare sensor. This allows pachinko balls to be detected by the spare sensor instead of the regular sensor even if the regular sensor is abnormal, so that the pachinko ball transfer system can be operated almost normally. Will not be disturbed.

  However, the above-described game medium storage amount detection device has the following problems.

  This is because the ball quantity sensor is composed of a regular sensor and a spare sensor, that is, since one spare sensor is installed for one regular sensor, the manufacturing cost is increased by the amount of the spare sensor. It was. In the first place, considering that the ball quantity sensor itself rarely causes abnormalities, the number of spare sensors should be as small as possible and the increase in manufacturing cost should be minimized. It ’s a good idea.

  However, for example, one spare sensor is installed for two regular sensors (for example, one spare sensor is installed at an intermediate point between two regular sensors, and one spare sensor is installed by two regular sensors. If the number of spare sensors is reduced more than necessary to reduce the manufacturing cost, the pachinko ball is detected by the spare sensor when the normal sensor malfunctions. There was a situation where it was impossible to achieve the original purpose of providing first aid. This is the case, for example, when unfortunately, the spare sensor first causes an abnormality. The applicant has considered that the manufacturer's manufacturing philosophy is to make every effort to operate the pachinko ball transfer system etc. almost normally while keeping the number of spare sensors as small as possible.

  Therefore, the present invention has been made in view of the above-described circumstances, and the purpose of the present invention is to make sure that it does not hinder the operation of the amusement hall even if the ball quantity sensor of the storage tank causes an abnormality.

FIG. 1 is an external perspective view of a pachinko island platform 1 according to the embodiment, and FIG. 2 is a longitudinal sectional view of the pachinko island platform 1 according to the embodiment. In FIG. 1, the pachinko island platform 1, as is well known, has a rectangular parallelepiped frame structure, and a pachinko machine 2 is arranged in parallel with the back on the side in the longitudinal direction. In a lower space below the counter stand 16 disposed at the lower end of the pachinko machine 2, a storage tank 9 (hereinafter may be referred to as a non-priority storage tank 9), a storage tank 10 (hereinafter referred to as a priority storage tank 10). In some cases). The storage tanks 9 and 10 are formed so large that a large amount of pachinko balls are stored. Specifically, the number of pachinko balls stored in the storage portions 9a and 10a formed in the storage tanks 9 and 10 is sufficient for various gaming states of the plurality of pachinko machines 2 installed on the pachinko island base 1 It is designed to have a size that can be dealt with (for example, 1 to 200,000 pieces each).

  In addition, the pachinko machine 1 has a ball return device (JC) 3 for returning the pachinko balls acquired by the pachinko machine 2 to one side of the ball feeding device storage unit 4 in the center thereof. It is provided in the shape. The ball return device 3 is preferably provided on the pachinko machine train side in which the non-priority storage tank 9 is built. This is because the non-priority storage tank 9 that is almost full in the normal business state can reliably return the prize balls from the ball return device 3. Further, this ball returning device 3 is also installed like the pachinko machine 2 so that the ball returning devices 3 on both sides of the pachinko island platform 1 face each other. The ball return device 3 has a return port 3a, and a pachinko ball (prize ball) returned from the return port 3a is provided in the upper part of the storage tank 9 via a connecting rod (not shown). In addition, it is guided onto the conveying rods 48 and 49.

When the JC shutter devices 31 and 32 (only the reference numerals are shown in FIG. 3) that are opened and closed by a drive source (for example, a motor or a solenoid) are closed, the return operation is prohibited and opened when the state is released. It is like that.

  In addition, a ball lifting device storage unit 4 is configured in the approximate center of the pachinko island stand 1, and a ball lifting device 5 is stored and installed in the ball lifting device storage unit 4. The ball lifting device 5 according to the present embodiment lifts pachinko balls by a belt-shaped transport belt (not shown), and the belt-shaped transport belt is longitudinal (orthogonal direction) with respect to the pachinko island platform 1. It is installed in and lifts pachinko balls to the top. An upper tank 6 for temporarily storing the pachinko balls that have been lifted is provided at the top of the ball lifting device 5. From the upper tank 6, replenishment rods (not shown) are provided on the left and right sides in an inclined manner so that pachinko balls flow down from the upper tank 6. A distribution chute (not shown) corresponding to each pachinko machine 2 is provided in the replenishing basket, and a pachinko ball that flows down the replenishing basket is taken in. Pachinko balls taken in by the distribution chute are counted by a counting device (not shown) provided at the lower portion of the distribution chute, and then supplied to a prize ball tank (not shown) provided at the upper back of the pachinko machine 2 to play the game. Is used as a prize ball to be paid out to the player. Further, as shown in FIG. 1, a pedestal ball lending machine 15 for lending the pachinko balls is provided so as to be sandwiched between the respective pachinko machines 2. Also connected to.

  On the other hand, the used balls discharged from each pachinko machine 2 are discharged downward from a ball discharge nozzle (not shown) of the out ball box 7 having a counting function. This ball discharge nozzle is arranged facing the upper priority rods 50 and 29 provided at the upper portions of the storage tanks 9 and 10, respectively. Accordingly, the pachinko balls discharged from the out ball box 7 are guided to the upper priority basket 50 in the storage tank 9 or the upper priority basket 29 in the storage tank 10. In addition, since the storage tanks 9 and 10 are each formed in a length corresponding to 3 to 4 pachinko machines 2 (a so-called 1-unit island length), the storage tanks 9 and 10 are stored in the units. When unit islands are further connected to the outside of the island (in many cases, connected), an out ball guide rail 8 is provided at the lower center of the unit island connected to the outside of the islands, The used balls discharged from the pachinko machine 2 deviated from the upper position are received. The downstream ends of the out ball guide rails 8 communicate with relay boxes 51 and 37 that are individually provided outside the upstream portions of the storage tanks 9 and 10, respectively.

  The relay boxes 51 and 37 also communicate with the downstream ends of the upper priority rods 50 and 29, respectively. The used balls discharged from the pachinko machine 2 to the out ball guide rail 8 and the used balls discharged from the pachinko machine 2 to the upper priority basket 50 are fed into the relay box 51 of the storage tank 9. The used balls are provided in the storage tank 9 and guided to a non-priority storage tank ball outlet to be described later via a priority rod 24 communicating with the relay box 51. Further, the used balls discharged from the pachinko machine 2 to the out ball guide rail 8 and the used balls discharged from the pachinko machine 2 to the upper priority basket 29 are fed into the relay box 37 of the storage tank 10. The used balls are provided in the storage tank 10 and guided to a priority tank first ball outlet which will be described later via a priority rod 52 communicating with the relay box 37.

  An overflow box 11 for returning the pachinko balls overflowed from the upper tank 6 to the lower part is connected to the storage tanks 9 and 10. The overflow box 11 is a rectangular parallelepiped box provided so as to use the adjacent space of the ball lifting device 5, and the inside thereof is partitioned in the vertical direction by the branch partition 12. The branch partition 12 is provided close to one side of the overflow box 11, and a plurality of flow-down plates 12a are alternately provided in a step shape in a passage on one side communicating with the wide area to constitute a box priority passage 11a. The box non-priority passage 11b is configured by alternately providing a plurality of descending plates 12a in steps in the other passage communicating with the narrow region. That is, the pachinko balls overflowed from the upper tank 6 are preferentially guided to the box priority passage 11a, and overflow to the box non-priority passage 11b when the box priority passage 11a is full. The box priority passage 11a and the box non-priority passage 11b are stored on the right storage tank 9 and the left storage via upper plates 47 and 26 formed on the upper parts of the storage tanks 9 and 10 on the ball lifting device 5 side, respectively. The tank 10 communicates with the tank 10.

  And the pachinko ball led to the box priority passage 11a passes through the box priority passage 11a, and then flows down the upper plate 26 and the transport rods 27, 28 provided in the upper portion of the storage tank 10, and then the storage tank The pachinko balls stored and stored at 10 are guided to a priority tank second ball outlet which will be described later.

  Further, the pachinko balls overflowing in the box non-priority passage 11b are filled with the box priority passage 11a, and after passing through the box non-priority passage 11b, the transport plate provided in the upper plate 47 and the upper portion of the storage tank 9 After flowing down 48 and 49, the pachinko balls stored and stored in the storage tank 9 are guided to the non-priority storage tank ball outlet described later.

  Thus, in this embodiment, since the overflow mechanism is configured in a box shape instead of the conventional flexible pipe, it is possible to extremely reduce the generation of noise due to the recirculated pachinko balls and not only the recirculation function. Since there is also a storage function for storing a considerable amount of pachinko balls (about 2 to 30,000 in this embodiment), it is effective as a storage space inside the pachinko island platform 1 using a space that has not been used conventionally. Can be used.

  Further, regular sensors (game medium detecting means) S1 (first regular sensor) to S6 for detecting the amount of stored balls (sometimes simply referred to as a stored amount) are provided on the inner side walls of the storage tanks 9 and 10, respectively. (6th regular sensor) is provided in steps according to the storage amount of the pachinko ball. According to the experiments by the present applicants, it has been found that the change in storage of the pachinko balls in the storage tanks 9 and 10 stays in a substantially horizontal direction from the upstream side of the storage tanks 9 and 10. For this reason, the regular sensors S1 to S6 are arranged in a substantially horizontal straight line so as to match the change in storage of the pachinko balls in the storage tanks 9 and 10 and are arranged on the upstream side of the priority storage tank 10. While the lower limit of the storage amount is detected by the normal sensor S1, the upper limit of the storage amount is detected by the sixth normal sensor S6 disposed on the downstream side of the non-priority storage tank 9. Therefore, as the amount of pachinko balls stored in the storage tank 10 increases, the pachinko balls are detected in the order of the regular sensors S1, S2, S3, and as the amount of pachinko balls stored in the storage tank 9 increases, the regular sensors S4, S5. , S6 will be detected in the order of S6.

  Further, on the side of the regular sensors S1 to S6, as with the regular sensors S1 to S6, a spare sensor (game medium spare detection means) S11 (first spare sensor) to S18 (eighth) for detecting the amount of stored balls. A preliminary sensor) is provided as a preliminary for the regular sensors S1 to S6. As shown in FIG. 2, the first preliminary sensor S11 is located on the upstream side of the first regular sensor S1, and the second preliminary sensor S12 is approximately halfway between the first regular sensor S1 and the second regular sensor S2. The third preliminary sensor S13 is provided approximately in the middle between the second regular sensor S2 and the third regular sensor S3, and the fourth preliminary sensor 14 is provided on the downstream side of the third regular sensor S3. Further, the fifth preliminary sensor S15 is located on the upstream side of the fourth regular sensor S4, and the sixth spare sensor S16 is located approximately halfway between the fourth regular sensor S4 and the fifth regular sensor S5. S17 is provided approximately halfway between the fifth regular sensor S5 and the sixth regular sensor S6, and the eighth preliminary sensor 18 is provided on the downstream side of the sixth regular sensor S6. Thus, the regular sensors S1 to S3 and the spare sensors S11 to S14 are alternately arranged from the upstream side to the downstream side of the storage tank 10 so that the spare sensors S11 and S14 are located at both ends thereof. Similarly, the regular sensors S4 to S6 and the spare sensors S15 to S18 are alternately arranged from the upstream side to the downstream side of the storage tank 9 so that the spare sensors S15 and S18 are located at both ends thereof. And based on the detection signal of these regular sensors S1-S6 and spare sensors S11-S18, the pachinko ball storage amount display device (game medium storage amount display device) 21 attached to the predetermined location of the pachinko island stand 1 is included. The display device 17 visually notifies the storage amount of the pachinko balls in the storage tanks 9 and 10, the states of the normal sensors S1 to S6 and the spare sensors S11 to S18 (whether they are normal or abnormal), and the like. ing. The display device 17 including the regular sensors S1 to S6, the spare sensors S11 to S18, and the pachinko ball storage amount display device 21 will be described in detail later.

  Next, various components disposed between the non-priority storage tank 9 and the priority storage tank 10 will be described. Between each of the storage tanks 9 and 10, a priority tank first ball outlet (not shown) formed in the priority tank 10 and a non-priority tank first ball inlet (not shown) formed in the non-priority tank 9. Connecting the connection rod 59, the priority tank second ball outlet (not shown) formed in the priority tank 10 and the non-priority tank second ball inlet (not shown) formed in the non-priority tank 9. A small ball lifting device 60 is provided. The small ball feeding device 60 is configured by supporting a conveyance path 62 in an inclined shape, connecting an introduction rod 63 on one lower side of the conveyance path 62, and connecting a discharge rod 64 on the other upper side thereof. The end portion of the introduction rod 63 is connected to the priority tank second ball outlet, and the end portion of the discharge rod 64 is connected to the non-priority tank second ball introduction port. Although not shown in detail in the conveyance path 62, a conveyor belt having ball locking strips formed in parallel is provided so as to turn, and this turning drive is performed by a motor provided on a substrate (not shown). This is performed by a V-belt (not shown) that is stretched between a pulley (not shown) fixed to an output shaft (not shown) and a roller (not shown) that drives the conveyor belt. Further, although not shown in detail in the conveyance path 62, an abnormality detection sensor is provided for detecting an abnormality when the conveyor belt is driven. As will be described later, the small ball feeding device 60 is provided with an abnormality detection sensor. An idling abnormality and a clogging abnormality can be detected immediately, and the occurrence of the abnormality can be reliably performed.

  Thus, the pachinko balls derived from the priority tank first ball outlet port flow down the connection rod 59 and are transferred to the non-priority tank first ball inlet port. On the other hand, the pachinko balls led out from the priority tank second ball outlet are fed into the conveying path 62 of the small ball feeding device 60 through the introduction rod 63, and are discharged after being fed along with the drive of the conveyor belt. It is transferred to the non-priority tank second ball inlet through the cage 64.

  Thus, in the pachinko island platform 1 according to the present embodiment, the pachinko balls stored in the non-priority storage tank 9 are introduced from a non-priority storage tank ball outlet (not shown) formed in the non-priority storage tank 9. It is fed into the ball lifting device 5 through the cage 72. On the other hand, the pachinko balls stored in the priority storage tank 10 flow down on the inclined bottom plate 41 provided in the priority storage tank 10 and are led to the small ball lifting device 60, and then the small ball lifting device. 60, it is fed to the non-priority storage tank 9 and sent to the ball lifting device 5 from the non-priority storage tank ball outlet through the introduction rod 72 in the same manner as described above. For this reason, the transfer of the pachinko balls from the priority storage tank 10 to the ball lifting device 5 is performed smoothly, and the ball lifting device 5 can always be driven efficiently.

  The non-priority storage tank ball outlet of the non-priority storage tank 9 is provided with a shutter device (not shown) that opens and closes the non-priority storage tank ball outlet. The shutter device normally opens the non-priority storage tank ball outlet and allows the pachinko ball to flow to the ball lifting device 5, while an abnormality such as a failure of the ball lifting device 5 occurs or at the end of business. The non-priority storage tank ball outlet is closed to prevent the pachinko ball from flowing down to the ball lifting device 5.

  As mentioned above, although the structure of the pachinko island stand 1 which concerns on this embodiment was demonstrated, the normal sensor S1-S6 which comprises the principal part of this embodiment next, the spare sensors S11-S18, and the pachinko ball storage amount display apparatus 21 are included. The display device 17 will be described with reference to FIGS. FIG. 3 is a block diagram showing the configuration of the control system of the pachinko island platform 1, FIG. 4 is a front view of the display device 17 including the pachinko ball storage amount display device 21, and FIGS. It is operation | movement explanatory drawing of the ball storage amount display apparatus 21, and FIG.7 and FIG.8 is a flowchart which shows a sensor adoption routine.

  In the block diagram shown in FIG. 3, regular sensors S <b> 1 to S <b> 6 provided in the storage tanks 9 and 10, and spare sensors S <b> 11 to S <b> 18 provided in the storage tanks 9 and 10 are provided on the control board 18 provided in the pachinko island base 1. The first JC shutter device 31, the second JC shutter device 32, and the small ball feeding device (described as a conveyor) 60 provided in the display device 17 and the two ball return devices 3 are connected.

  Further, the display device 17 shown in FIG. 4 includes a storage amount display unit 19 that displays the storage amount of the pachinko balls in the storage tanks 9 and 10 in stages, and a normal state in which the spare sensors S11 to S18 can detect the pachinko balls. A pachinko ball storage amount display device (game medium storage amount display) having a preliminary sensor state display unit (preliminary detection unit state display unit (notification unit)) 20 that displays whether the state or an abnormal state that cannot be detected Device) 21, JC shutter display units 31a and 32a for displaying whether the first JC shutter device 31 and the second JC shutter device 32 are open and in a normal state, and the small ball feeding device 60 are operated. A conveyor lamp 34 is provided for displaying whether or not it is normal and whether or not it is normal.

  The storage amount display unit 19 described above displays the storage amount of the pachinko balls step by step with a predetermined number (six in the case of the embodiment) of ball amount level display lamps 19a to 19f. Further, the preliminary sensor status display unit 20 as the notification means described above is configured by preliminary sensor status display lamps 20a to 20h corresponding to the ball amount level display lamps 19a to 19f of the storage amount display unit 19, respectively. The spare sensor state display lamps 20a to 20h of the spare sensor state display unit 20 correspond to the respective ball quantity level display lamps 19a to 19f of the storage amount display unit 19 corresponding to the spare sensor state display lamps 20a to 20h. They are connected by corresponding instruction means 22a to 22l that can recognize that they are in a relationship, and are arranged in correspondence with the respective ball quantity level display lamps 19a to 19f. That is, the spare sensor status display lamp 20a is associated with the ball quantity level display lamp 19a and the corresponding instruction means 22a, and the spare sensor status display lamp 20b is associated with the ball quantity level display lamp 19a and the ball quantity level display lamp 19b, respectively. , 22c, the spare sensor state display lamp 20c is replaced with the ball amount level display lamp 19b and the ball amount level display lamp 19c, and the corresponding instruction means 22d, 22e, respectively, and the spare sensor state display lamp 20d is replaced with the ball amount level display lamp 19c. They are arranged in a display mode connected by the corresponding instruction means 22f. Similarly, the spare sensor state display lamp 20e is associated with the ball amount level display lamp 19d and the corresponding instruction means 22g, and the spare sensor state display lamp 20f is associated with the ball amount level display lamp 19d and the ball amount level display lamp 19e, respectively. By 22h and 22i, the spare sensor state display lamp 20g is changed by the ball quantity level display lamp 19e and the ball quantity level display lamp 19f and the corresponding instruction means 22j and 22k, respectively. Are arranged in a display mode connected by the corresponding instruction means 22l.

  The JC shutter display units 31a and 32a include JC “closed” lamps 31b and 32b that are turned on when the JC shutter is closed, and JC “open” lamps 31c and 32c that are turned on when the JC shutter is opened. It is composed of

  The control board 18 receives signals indicating the states of the first JC shutter device 31 and the second JC shutter device 32, and based on the received signals, the JC shutter display units 31a and 32a use the first JC shutter device 31 and the second JC shutter. The status of the device 32 is displayed. Specifically, as shown in FIG. 5, JC shutter devices 31 and 32 (indicated simply as shutters in FIG. 5) open the return port 3 a of the ball return device (indicated as JC in FIG. 5) 3. In this manner (in FIG. 5, when the JC shutter is in the open state), the JC “open” lamps 31c and 32c are lit in green and the JC “closed” lamps 31b and 32b are turned off. However, even if the shutter of the ball return device 3 is open, the JC “open” lamps 31c and 32c are lit in red in an abnormal state or a state where the shutter is opened illegally. In such a case, for example, although an open signal is transmitted to the JC shutter devices 31 and 32, a shutter open signal is transmitted from this sensor due to a failure of the sensor that detects the opening and closing of the shutter. If the shutter is not opened, or the opening signal is not transmitted to the JC shutter devices 31 and 32, the shutter is opened from the outside improperly or due to a shutter failure. This is the case when a shutter opening signal is transmitted from a sensor that detects opening and closing of the shutter.

  Further, when the JC shutter devices 31 and 32 are working so as to close the shutter of the ball return device 3 (in FIG. 5, when the JC shutter is in the closed state), the JC “closed” lamps 31b and 32b are It lights up in green and the JC “open” lamps 31c, 32c are turned off. However, even when the shutter of the ball return device 3 is closed, the JC “closed” lamps 31b and 32b are lit in red in an abnormal state or a state where the shutter is closed illegally. In such a case, for example, although a closing signal is transmitted to the JC shutter devices 31 and 32, a shutter closing signal is transmitted from this sensor due to a failure of the sensor that detects opening and closing of the shutter. If not, or even if no closing signal is transmitted to the JC shutter devices 31 and 32, the shutter is improperly closed from the outside, or remains closed due to a shutter failure. This is the case when a shutter closing signal is transmitted from a sensor that detects opening and closing of the shutter.

  The control board 18 receives a signal (operation signal) indicating the state of the small ball lifting device (indicated as a conveyor in FIG. 5) 60, and the conveyor lamp 34 of the display device 17 based on the received signal. The state of the small ball lifting device 60 is displayed. Specifically, as shown in FIG. 5, when the small ball lifting device 60 is operating, the conveyor lamp 34 is lit in green, and when it is not operating, the conveyor lamp 34 is turned off. . However, even when the small ball lifting device 60 is in operation, the conveyor lamp 34 is lit in red when operating in an abnormal state. As such a case, for example, although an operation signal is transmitted to the small ball lifting device 60, the small ball lifting device 60 may be clogged with pachinko balls, accumulated dust / dust, etc. This is the case, for example, when the drive motor for driving the small ball feeding device 60 is stopped or in a state where the rotational speed is insufficient.

  The control board 18 receives the detection signals from the regular sensors S1 to S6 and the spare sensors S11 to S18, and the storage tank 9 in the storage amount display unit 19 of the pachinko ball amount display device 21 based on the received signals. , 10 pachinko ball storage amount is displayed. Further, in this case, the control board 18 serves as an abnormality determination means for determining whether the normal sensors S1 to S6 and the spare sensors S11 to S18 are in a normal state where the pachinko balls can be detected or in an abnormal state where the pachinko balls cannot be detected. It functions, and based on the determination result, the states of the regular sensors S1 to S6 and the spare sensors S11 to S18 are displayed on the storage amount display unit 19 and the spare sensor state display unit 20 of the pachinko ball amount display device 21. The control substrate 18 serving as the abnormality determining means, the regular sensors S1 to S6 serving as the game medium regular detecting means, and the spare sensors S11 to S18 serving as the game medium preliminary detecting means constitute a gaming medium storage amount detecting device. is there.

  Specifically, as the amount of pachinko balls stored in the storage tanks 9 and 10 increases and is sequentially detected by the regular sensors S1 to S6 or the spare sensors S11 to S18, the regular sensors S1 to S6 or the spare sensors S11 to S11. The ball amount level display lamps 19a to 19f of the storage amount display unit 19 corresponding to S18 are lit or blinking in green in the order of 19a, ..., 19f. At this time, as shown in FIG. 6, when the sensors detecting the pachinko balls are the regular sensors S1 to S6, the ball amount level display lamps 19a to 19f are lit in green (first mode), On the other hand, when the sensors that have detected the pachinko balls due to any abnormality caused by the normal sensors S1 to S6 are the spare sensors S11 to S18, the ball amount level display lamps 19a to 19f flash green ( (Third aspect). Further, when the normal sensors S1 to S6 and the spare sensors S11 to S18 are abnormal, or when no pachinko balls are detected, the ball amount level display lamps 19a to 19f are turned off (second mode). ) Thereby, the storage amount of the pachinko balls in the storage tanks 9 and 10 can be visually recognized by the storage amount display unit 19. Further, the storage amount display unit 19 can recognize at least whether the normal sensors S1 to S6 are in a normal state or an abnormal state, and when the normal sensors S1 to S6 are in an abnormal state, the spare sensors S11 to S18 perform pachinko. It can be easily recognized that a ball is detected.

  It should be noted that in the “second mode” of the ball amount level display lamps 19a to 19f described above, whether the normal sensors S1 to S6 and the spare sensors S11 to S18 are abnormal, or simply a pachinko ball is used. Whether it is not detected can be grasped somehow only by looking at the storage amount display unit 19, but cannot be accurately grasped. Therefore, if a reserve sensor state display unit 20 described later attached to the storage amount display unit 19 is used, that is, if the reserve sensor state display unit 20 is also referred to when the storage amount display unit 19 is viewed, the storage amount display unit 19 is accurately The state of the normal sensors S1 to S6 in the “second mode” of the ball amount level display lamps 19a to 19f can be grasped.

  As described above, the pachinko balls in the storage tanks 9 and 10 are detected by either the regular sensors S1 to S6 or the spare sensors S11 to S18, but are usually detected by the regular sensors S1 to S6, and an abnormality is determined. When it is determined by the control board 18 as a means that the normal sensors S1 to S6 are in an abnormal state in which pachinko balls cannot be detected, they are automatically switched to the spare sensors S11 to S18 corresponding to the normal sensors S1 to S6. The pachinko balls are detected by the switched preliminary sensors S11 to S18. Specifically, in the storage tank 10, when the regular sensor S1 is determined to be in an abnormal state by the control board 18, a pachinko ball is detected by the spare sensor S11 or the spare sensor S12 instead of the regular sensor S1. When it is determined that the normal sensor S2 is in an abnormal state by the control board 18, a pachinko ball is detected by the spare sensor S12 or the spare sensor S13 instead of the normal sensor S2, and the normal sensor S3 is abnormal by the control board 18. When it is determined that the state is the state, the pachinko ball is detected by the spare sensor S13 or the spare sensor S14.

  In the storage tank 9, when it is determined by the control board 18 that the normal sensor S4 is in an abnormal state, a pachinko ball is detected by the spare sensor S15 or the spare sensor S16 instead of the regular sensor S4. If it is determined that the control board 18 is in an abnormal state, the pachinko ball is detected by the spare sensor S16 or the spare sensor S17 instead of the regular sensor S5, and the regular sensor S6 is in an abnormal state by the control board 18. When it is determined that the pachinko ball is detected by the spare sensor S17 or the spare sensor S18 instead of the regular sensor S6.

  Thus, the spare sensor S12 is also used as a spare sensor for the regular sensors S1 and S2, the spare sensor S13 is also used as a spare sensor for the regular sensors S2 and S3, and the spare sensor S16 is a spare sensor for the regular sensors S4 and S5. The spare sensor S17 is also used as a spare sensor for the regular sensors S5 and S6. At this time, as shown in FIG. 2, the spare sensors S11 to S18 are installed at positions different from the regular sensors S1 to S6. Therefore, when the spare sensors S11 to S18 are used, Unlike the amount of pachinko balls stored when the regular sensors S1 to S6 are used, this is an approximate numerical value.

  Note that, as described in (Note 1) in FIG. 6, when the second preliminary sensor is first adopted, it is treated as “abnormal”. This is because, for example, in the relationship between the regular sensor S1 and the regular sensor S2 that also use the second spare sensor S12 as the spare sensor, the second spare sensor S12 is already in the second state because the second regular sensor S2 is determined to be abnormal. When it is employed as a spare sensor for the second regular sensor S2, the first spare sensor S11 cannot be employed as a spare sensor for the first regular sensor S1, and therefore the first spare sensor S11 in the first regular sensor S1. This means that the second preliminary sensor S12 is treated as abnormal even if it is not abnormal. Similarly, when the second spare sensor S12 has already been adopted as a spare sensor for the first regular sensor S1, the first spare sensor S11 is abnormal in the determination of the second spare sensor S12 in the second regular sensor S2. Even if not, it is treated as abnormal. Further, the relationship between the regular sensor S2 and the regular sensor S3 that also serves as the spare sensor, the third spare sensor S13 described in (Note 2), and the regular sensor S4 that also serves as the spare sensor, the sixth spare sensor S16 described in (Note 3). The same applies to the relationship between the normal sensor S5 and the normal sensor S5, and the relationship between the normal sensor S5 and the normal sensor S6, which also uses the seventh preliminary sensor S17 described in (Note 4) as a preliminary sensor.

  Therefore, the control means 18 also includes sensor monitoring means (detection means monitoring means) for monitoring all of the regular sensors S1 to S6 and the spare sensors S11 to S18 for each predetermined unit. That is, the abnormality determination means in the present application includes detection means monitoring means.

  It is determined that the normal sensors S1 to S6 are in an abnormal state in which the pachinko balls cannot be detected, and after the pachinko balls are approximated by the spare sensors S11 to S18, for example, the normal sensors that are in an abnormal state When it is determined that the normal sensors S1 to S6 are in the normal state again by exchanging S1 to S6, the normal sensors S1 to S1 that are determined to be in the normal state again are not the spare sensors S11 to S18. It is controlled by the control board 18 so that the pachinko ball is detected by S6. That is, the spare sensors S11 to S18 are automatically returned to normal normal sensors S1 to S6. Thereby, there is no forgetting to return from the spare sensors S11 to S18 to the normal normal sensors S1 to S6.

  Further, as described above, the control board 18 determines whether the preliminary sensors S11 to S18 are in a normal state where the pachinko balls can be detected or an abnormal state where the pachinko balls are not detected, and based on the determination result, The states of the spare sensors S11 to S18 are displayed on the spare sensor state display unit 20 as a notification means. Specifically, as shown in FIG. 6, when the spare sensors S11 to S18 are in a normal state, the spare sensor state display lamps 20a to 20h of the spare sensor state display unit 20 are lit in green. Further, when the spare sensors S11 to S18 are in an abnormal state, the spare sensor state display lamps 20a to 20h are lit in red.

  In this way, since the spare sensor state display unit 20 displays whether the spare sensors S11 to S18 are in a normal state or an abnormal state, the spare sensors S11 to S18 are visually recognized as being in a normal state or an abnormal state. Therefore, even if the spare sensors S11 to S18 cause an abnormality before the regular sensors S1 to S6, the spare sensor state display unit 20 can recognize the abnormality, so that the spare sensors S11 to S18 are replaced. The necessary treatment such as can be performed quickly.

  Further, as described above, the spare sensor state display unit 20 can visually recognize that the storage amount display unit 19 corresponding to the spare sensor state display unit 20 is in a corresponding relationship with each other. ˜221) are arranged in correspondence with the storage amount display unit 19. For example, the ball amount level display lamp 19a of the storage amount display unit 19 and the spare sensor state display lamps 20a and 20b of the spare sensor state display unit 20 are arranged in a display mode connected by corresponding instruction means 22a and 22b, respectively. Yes. The spare sensor state display lamp 20b is arranged in a display mode connected to the ball quantity level display lamps 19a and 19b of the storage amount display unit 19 by the corresponding instruction means 22b and 22c, respectively. For this reason, it can be easily recognized at which position the spare sensors S11 to S18 are abnormal.

  As described above, the functions of the control board 18 and the display device 17 have been described. Next, with regard to control of which of the regular sensors S1 to S6 or the spare sensors S11 to S18 performed by the control board 18 described above, FIG. This will be described with reference to the flowchart of FIG.

  In the process shown in FIG. 7, first, in step S100, the detection state is determined based on the detection signal of the first regular sensor S1. As a method for determining the detection state, a constant current is supplied from the control board 18 to the first normal sensor S1, and the voltage applied to the first normal sensor S1 is monitored by the current by the control board 18 to detect the detection state. Judging. Since the first regular sensor S1 changes in resistance according to the states of “disconnection”, “with ball”, “without ball”, and “short circuit”, when the current is constant as described above, The voltage applied to the first regular sensor S1 also changes according to each state described above. Therefore, by monitoring this voltage, it is possible to determine which state the first normal sensor S1 is in. Specific values of the voltage are 0.00 to 0.09 V when “disconnected”, 0.14 to 1.06 V when “with ball”, 4.40 to 7.20 V when “without ball”, and “short circuit”. When it is 8.67 to 12.0V.

  When the voltage applied to the first normal sensor S1 becomes 0.14 to 1.06 V or 4.40 to 7.20 V, that is, “with ball” or “without ball”, in step S100, the first normal sensor After it is determined that the sensor S1 is not abnormal (NO in step S100) and the first regular sensor S1 is employed (step S101), the process proceeds to step S107.

  On the other hand, when the voltage applied to the first normal sensor S1 becomes 0.00 to 0.09 V or 8.67 to 12.0 V, that is, when it is “disconnected” or “short circuit”, the first normal sensor is detected in step S100. After it is determined that S1 is abnormal (YES in step S100), the state of the first preliminary sensor S11 is determined in the same manner as the first normal sensor S1 (step S102). When the first spare sensor S11 is “with ball” or “without ball”, it is determined in step S102 that the first spare sensor S11 is not abnormal (NO in step S102), and after the first spare sensor S11 is employed. (Step S103), the process proceeds to Step S107. When the first preliminary sensor S11 is “disconnected” or “short circuit”, it is determined in step S102 that the first preliminary sensor S11 is abnormal (YES in step S102), and the process directly proceeds to step S104.

  In step S104 described above, it is determined whether or not the second preliminary sensor S12 is being employed (step S104). If it is determined in step S104 that the second spare sensor S12 is being employed, that is, the second spare sensor S12 has been previously used as a spare sensor for the second regular sensor S2 (YES in step S104), step S107 is performed as it is. Proceed to If it is determined in step S104 that the second preliminary sensor S12 is not being employed (NO in step S104), the state of the second preliminary sensor S12 is determined (step S105). When the second spare sensor S12 is “with ball” or “without ball”, it is determined in step S105 that the second spare sensor S12 is not abnormal (NO in step S105), and the second spare sensor S12 is employed. (Step S106), the process proceeds to Step S107. If the second preliminary sensor S12 is “disconnected” or “short-circuited”, it is determined in step S105 that the second preliminary sensor S12 is abnormal (YES in step S105), and the process directly proceeds to step S107.

  As described above, when it is determined that the first normal sensor S1 is not abnormal, a pachinko ball is detected using the first normal sensor S1. Further, when it is determined that the first normal sensor S1 is abnormal and when it is determined that the first preliminary sensor S11 is not abnormal, the pachinko ball is detected using the first preliminary sensor S11. Further, when it is determined that the first preliminary sensor S11 is abnormal, the second preliminary sensor S12 has not been previously used as the preliminary sensor for the second regular sensor S2, and the second preliminary sensor S12 is not used. If it is determined that there is no abnormality, the pachinko ball is detected using the second preliminary sensor S12. Further, when it is determined that the first normal sensor S1 is abnormal, the second preliminary sensor S12 has been previously used as a preliminary sensor for the second normal sensor S2, or the second preliminary sensor S12 is abnormal. If it is determined that the first normal sensor S1, the first preliminary sensor S11, and the second preliminary sensor S12 are not used, the sensor is not employed.

  As described above, when it is determined that the first normal sensor S1 is abnormal and the spare sensor is employed, it is first determined whether or not the first spare sensor S11 can be employed, and the first spare sensor S11 cannot be employed. When it is determined, it is next determined whether or not the second preliminary sensor S12 can be employed.

  Next, in step S107 described above, the state of the second normal sensor S2 is determined by the same method as described above (step S107). When the second regular sensor S2 is “with ball” or “without ball”, it is determined in step S107 that the second regular sensor S2 is not abnormal (NO in step S107), and after the second regular sensor S2 is employed. (Step S108), the process proceeds to Step S115.

  On the other hand, when the second normal sensor S2 is “disconnected” or “short circuit”, the second preliminary sensor S12 is adopted after it is determined in step S107 that the second normal sensor S2 is abnormal (YES in step S107). It is determined whether it is in the middle (step S109). If it is determined in step S109 that the second preliminary sensor S12 is being employed, that is, the second preliminary sensor S12 has been previously used as a preliminary sensor for the first regular sensor S1 (YES in step S109), the process proceeds to step S112. Proceed to If it is determined in step S109 that the second preliminary sensor S12 is not being employed (NO in step S109), the state of the second preliminary sensor S12 is determined (step S110). When the first spare sensor S11 is “with ball” or “without ball”, it is determined in step S110 that the second spare sensor S12 is not abnormal (NO in step S110), and the second spare sensor S12 is employed. (Step S111), the process proceeds to Step S115. When the second preliminary sensor S12 is “disconnected” or “short-circuited”, it is determined in step S110 that the second preliminary sensor S12 is abnormal (YES in step S110), and the process directly proceeds to step S112.

  In step S112 described above, it is determined whether the third preliminary sensor S13 is being employed (step S112). If it is determined in step S112 that the third preliminary sensor S13 is being employed, that is, the third preliminary sensor S13 has been used as a preliminary sensor for the third regular sensor S3 (YES in step S112), step S115 is performed as it is. Proceed to If it is determined in step S112 that the third preliminary sensor S13 is not being employed (NO in step S112), the state of the third preliminary sensor S13 is determined (step S113). When the third preliminary sensor S13 is “with ball” or “without ball”, it is determined in step S113 that the third preliminary sensor S13 is not abnormal (NO in step S113), and the third preliminary sensor S13 is employed. (Step S114), the process proceeds to Step S115. When the third preliminary sensor S13 is “disconnected” or “short circuit”, it is determined in step S113 that the third preliminary sensor S13 is abnormal (YES in step S113), and the process directly proceeds to step S115.

  As described above, when it is determined that the second regular sensor S2 is not abnormal, the pachinko ball is detected using the second regular sensor S2. Further, when it is determined that the second regular sensor S2 is abnormal, the second spare sensor S12 has not been previously used as a spare sensor for the first regular sensor S1, and the second spare sensor S12 is not used. If it is determined that there is no abnormality, the pachinko ball is detected using the second preliminary sensor S12. The second preliminary sensor S12 is used as a preliminary sensor for the first regular sensor S1, or it is determined that the second preliminary sensor S12 is abnormal, and the third preliminary sensor S13 is the third regular sensor. When it is determined that the third preliminary sensor S13 is not abnormal before being used as the preliminary sensor of S3, the pachinko ball is detected using the third preliminary sensor S13. The second preliminary sensor S12 is used as a preliminary sensor for the first regular sensor S1, or it is determined that the second preliminary sensor S12 is abnormal, and the third preliminary sensor S13 is the third regular sensor. If the third preliminary sensor S13 has been previously used as the preliminary sensor for S3 or if the third preliminary sensor S13 is determined to be abnormal, any one of the second regular sensor S2, the second preliminary sensor S12, and the third preliminary sensor S13 is used. The sensor will not be adopted.

  As described above, when it is determined that the second regular sensor S2 is abnormal and the spare sensor is employed, it is determined whether or not the second spare sensor S12 can be employed first, and the second spare sensor S12 cannot be employed. When it is determined, it is next determined whether or not the third preliminary sensor S13 can be adopted.

  Next, in step S115 described above, the state of the third normal sensor S3 is determined by the same method as described above (step S115). When the third normal sensor S3 is “with ball” or “without ball”, it is determined in step S115 that the third normal sensor S3 is not abnormal (NO in step S115), and after the third normal sensor S3 is employed. (Step S116), the process proceeds to Step S122.

  On the other hand, when the third normal sensor S3 is “disconnected” or “short-circuited”, it is determined in step S115 that the third normal sensor S3 is abnormal (YES in step S115), and then the fourth preliminary sensor S14. The state is determined (step S117). When the fourth preliminary sensor S14 is “with ball” or “without ball”, it is determined in step S117 that the fourth preliminary sensor S14 is not abnormal (NO in step S117), and the fourth preliminary sensor S14 is employed. (Step S118), the process proceeds to Step S122. When the fourth preliminary sensor S14 is “disconnected” or “short-circuited”, it is determined in step S117 that the fourth preliminary sensor S14 is abnormal (YES in step S117), and the process directly proceeds to step S119.

  In step S119 described above, it is determined whether or not the third preliminary sensor S13 is being employed (step S119). If it is determined in step S119 that the third spare sensor S13 is being employed, that is, if the third spare sensor S13 has been previously used as a spare sensor for the second regular sensor S2 (YES in step S119), the process proceeds to step S122. Proceed to If it is determined in step S119 that the third preliminary sensor S13 is not being adopted (NO in step S119), the state of the third preliminary sensor S13 is determined (step S120). When the third spare sensor S13 is “with ball” or “without ball”, it is determined in step S120 that the third spare sensor S13 is not abnormal (NO in step S120), and the third spare sensor S13 is employed. (Step S121), the process proceeds to Step S122. When the third preliminary sensor S13 is “disconnected” or “short-circuited”, it is determined in step S120 that the third preliminary sensor S13 is abnormal (YES in step S120), and the process directly proceeds to step S122.

  As described above, when it is determined that the third regular sensor S3 is not abnormal, a pachinko ball is detected using the third regular sensor S3. Further, when it is determined that the third normal sensor S3 is abnormal and when it is determined that the fourth preliminary sensor S14 is not abnormal, the pachinko ball is detected using the fourth preliminary sensor S14. Further, when it is determined that the fourth preliminary sensor S11 is abnormal, the third preliminary sensor S13 has not been previously used as the preliminary sensor for the second regular sensor S2, and the third preliminary sensor S13 is not used. If it is determined that there is no abnormality, the pachinko ball is detected using the third preliminary sensor S13. Further, when it is determined that the fourth regular sensor S4 is abnormal, the third preliminary sensor S13 has been previously used as the spare sensor for the second regular sensor S2, or the third preliminary sensor S13 is abnormal. If it is determined that any one of the third regular sensor S3, the fourth preliminary sensor S14, and the third preliminary sensor S13 is not employed.

  Thus, when it is determined that the third regular sensor S3 is abnormal and the spare sensor is employed, it is determined whether or not the fourth spare sensor S14 can be employed first, and the fourth spare sensor S14 cannot be employed. When it is determined, it is next determined whether or not the third preliminary sensor S13 can be adopted.

  When the third regular sensor S3 is determined to be abnormal in the above-described steps S115 to S121 and the spare sensor is adopted, it is not the third spare sensor S13 located on the upstream side but the downstream side first. For example, if the third spare sensor S13 is adopted first, the fourth spare sensor S14 is preferentially adopted. For example, if the third spare sensor S13 is adopted first, the switching destination in the second regular sensor S2 is only the second spare sensor S12. Because it will end up. That is, by configuring as in the present embodiment, it is possible to efficiently employ all the spare sensors.

  The sensor adoption routine related to the regular sensors S1 to S3 and the spare sensors S11 to S14 provided in the storage tank 10 has been described above with reference to steps S100 to S121 in FIG. 7, but is shown in steps S122 to S143 in FIG. Since the sensor adoption routine relating to the regular sensors S4 to S6 and the spare sensors S15 to S18 provided in the storage tank 9 is the same as the control flow of the above-described steps S100 to S121, detailed description thereof is omitted. In this case, the first regular sensor S1 to the third regular sensor S3 and the first spare sensor S11 to the fourth spare sensor S14 in FIG. 7 are replaced by the fourth regular sensor S4 to the sixth regular sensor S6 and the fifth spare sensor S14 in FIG. This corresponds to the spare sensor S15 to the eighth spare sensor S18. In addition, as a control flow, steps S100 to S106 showing the adoption routine of the first regular sensor S1, the first spare sensor S11 and the second spare sensor S12 are the fourth regular sensor S4, the fifth spare sensor S15 and the sixth spare sensor. Corresponding to steps S122 to S128 indicating the adoption routine of the sensor S16, steps S107 to S114 indicating the adoption routines of the second regular sensor S2, the second spare sensor S12 and the third spare sensor S13 are the fifth regular sensor S5, sixth. Corresponding to steps S129 to S136 showing the adoption routine of the spare sensor S16 and the seventh spare sensor S17, steps S115 to S121 showing the adoption routine of the third regular sensor S3, the third spare sensor S13 and the fourth spare sensor S14 are the first. 6 regular sensors S6, 7th spare sensor S17 and 8th spare sensor S18 Correspond to steps S137~S143 showing the adoption routine.

  As described above, the control of which of the regular sensors S1 to S6 or the spare sensors S11 to S18 performed by the control board 18 has been described, but in the above-described embodiment, the spare sensor state display of the pachinko ball storage amount display device 21 is performed. Although the part 20 showed what was comprised as an alerting | reporting means which alert | reports whether the spare sensors S11-S18 are a normal state or an abnormal state, it is not restricted to this, The spare sensor of the pachinko ball storage amount display apparatus 21 is shown. The state display unit 20 may be configured as a normal sensor state display unit (normal detection means state display unit) that displays whether the normal sensors S1 to S6 are in a normal state or an abnormal state. By doing so, it is possible to recognize whether the normal sensors S1 to S6 corresponding to the storage amount display unit 19 are in a normal state or an abnormal state, and when the normal sensors S1 to S6 are in an abnormal state, the spare sensors S11 to S11. It can be easily recognized that the pachinko ball is detected by S18.

  Further, the preliminary sensor state display unit 20 of the pachinko ball storage amount display device 21 is not limited to being configured as a notification unit that notifies whether the preliminary sensors S11 to S18 are in a normal state or an abnormal state. The reserve sensor state display unit 20 of the storage amount display device 21 displays normal and spare sensor state display units (regular and spare sensor states) that indicate whether the normal sensors S1 to S6 and the spare sensors S11 to S18 are in a normal state or an abnormal state. It may be configured as a detection means state display unit). By doing so, since it is possible to visually recognize whether the normal sensors S1 to S6 and the spare sensors S11 to S18 are in a normal state or an abnormal state, replacement of the regular sensors S1 to S6 and the spare sensors S11 to S18, etc. The maintenance time can be set in advance.

  In the above-described embodiment, as an example of a transfer system that is controlled using the game medium storage amount detection device, the storage amount as a game medium storage amount display device that displays the amount of stored balls in the storage tanks 9 and 10. Although the display part 19 was shown, of course, you may use for the well-known pachinko ball transfer system.

  By the way, in above-mentioned embodiment, even if it is a case where abnormality has occurred in the regular sensors S1 to S6 (game medium regular detection means) for detecting the storage amount of the pachinko balls (game medium) in the storage tanks 9 and 10. Instead of the regular sensors S1 to S6, the pachinko balls are detected by any one of the spare sensors S11 to S18 adjacent to the regular sensors S1 to S6 in which an abnormality has occurred, and the amount of the pachinko balls stored is estimated. As a result, the pachinko ball transfer system and the like can be operated almost normally by using fewer spare sensors S11 to S18, so that the production cost of the pachinko islands 1 is reduced and the business of the game hall is hindered. You can continue business without coming.

  In addition, since one normal sensor S1 to S6 can be switched with respect to the two spare sensors S11 to S18, it is possible to deal with the abnormality of the normal sensors S1 to S6 more fully. . Moreover, since the spare sensors S11 to S18 at the switching destination share the spare sensors S11 to S18 provided between the two regular sensors S1 to S6 adjacent to each other, the two regular sensors S1 to S6. For example, the number of spare sensors S11 to S18 can be reduced, for example, three spare sensors S11 to S18 are used instead of four for two regular sensors S1 to S6.

  In the above-described embodiment, after the normal sensors S1 to S6 are determined to be abnormal and the pachinko balls are detected by the spare sensors S11 to S18, the normal sensor S1 is replaced by replacing the normal sensors S1 to S6. When -S6 is determined to be normal, pachinko balls are detected by the normal sensors S1-S6 determined to be normal. That is, the spare sensors S11 to S18 are automatically returned to normal normal sensors S1 to S6. Thereby, there is no forgetting to return from the spare sensors S11 to S18 to the normal normal sensors S1 to S6.

  In the above-described embodiment, a pachinko ball storage amount display device 21 (game medium storage amount display device) having a storage amount display unit 19 that displays the storage amount of the pachinko balls in the storage tanks 9 and 10 is provided. When the pachinko balls in the storage tanks 9 and 10 are detected by the spare sensors S11 to S18, the storage amount display unit 19 detects the pachinko balls in the storage tanks 9 and 10 by the regular sensors S1 to S6, and the storage A mode different from the mode when the pachinko balls in the tanks 9 and 10 are not detected is used. Thereby, the storage amount of the pachinko balls in the storage tanks 9 and 10 can be visually recognized by the storage amount display unit 19. Further, the storage amount display unit 19 can recognize whether the normal sensors S1 to S6 and the spare sensors S11 to S18 are in a normal state or an abnormal state. If the normal sensors S1 to S6 are in an abnormal state, the spare sensor S11. It can be easily recognized that a pachinko ball is detected by ~ S18.

  Further, in the above-described embodiment, the pachinko ball storage amount display device 21 (game medium storage amount display device) provides a preliminary sensor state display unit that notifies whether the preliminary sensors S11 to S18 are in a normal state or an abnormal state. 20 (notification means), and the notification means is configured as a spare sensor state display section 20 (preliminary detection means state display section) for displaying whether the spare sensors S11 to S18 are in a normal state or an abnormal state. Since the unit 20 is arranged in correspondence with the storage unit display unit 19 (for example, the sensor state display unit 20 and the storage unit display unit 19 are arranged close to each other in the horizontal direction), the spare at which position It can be easily visually recognized whether the sensors S11 to S18 are abnormal. Further, since it is possible to visually recognize, for example, whether the spare sensors S11 to S18 are in a normal state or an abnormal state, a maintenance time such as replacement of the spare sensors S11 to S18 can be assumed in advance.

  Further, in the above-described embodiment, the pachinko ball storage amount display device 21 (game medium storage amount display device) provides a preliminary sensor state display unit that notifies whether the preliminary sensors S11 to S18 are in a normal state or an abnormal state. 20 (notification means), and the notification means is configured as a spare sensor state display unit 20 that displays whether the spare sensors S11 to S18 are in a normal state or an abnormal state, and displays a storage amount corresponding to the spare sensor state display unit 20. Since the corresponding instruction means 22 (22a to 22l) that can recognize that the units 19 are in correspondence with each other are provided, it is easy to visually determine at which position the spare sensors S11 to S18 are abnormal. Can be recognized.
