The game operation control section 53 exchanges signals with game parts on the game board 4 via the I / O port 52 to control the game operation on the game board 4 side. The notification control unit 54 controls the notification of each of the notification units 20 and 47 on condition that there are a disconnection signal and a short-circuit signal sent from the disconnection detection units 48 and 49 and the short-circuit detection units 50 and 51 via the I / O port 52. It is supposed to.

  The notifying means 20 and 47 are provided on condition that the disconnection detecting means 48 and 49 and the short-circuit detecting means 50 and 51 detect the disconnection and short-circuit when the ball detecting means 25 and 26 have a disconnection or short-circuit abnormality. This is for notifying the ball detecting means 25, 26 in which the disconnection or short circuit has occurred, and the cause of the abnormality (disconnection or short circuit).

  As shown in FIG. 5, the first notification means 20 includes two display units 55 and 56, each of which comprises a 7-segment display element or the like, on the left and right sides. In response to the short-circuit signal from the controller 51, the notification control unit 54 notifies the ball detecting means 25 and 26 in which the abnormality has occurred and the cause of the abnormality by numbers such as "1" and "2".

Further, first and second short-circuit notification means for notifying short-circuit of each ball detection means 25 and 26 by two upper and lower luminous bodies 59 and 60 corresponding to the display of ball detection means 25 and 26 and display of short-circuit. When the short circuit occurs on the ball detecting means 25, 26 side, the corresponding light emitting bodies 59, 60 emit light under the control of the notification control unit 54.

  Note that the disconnection notifying unit constitutes a first abnormality notifying unit, and the short-circuit notifying unit constitutes a second abnormality notifying unit. The indications of the ball detecting means 25 and 26 on the main control board 36 side, the indications of disconnection and short-circuit, and the respective illuminants 57 to 60 are visible from the outside of the transparent main control board case 37.

  The abnormality information external output means 70 is for enabling the disconnection abnormality information from the disconnection detection means 48, 49 and the short-circuit abnormality information from the short-circuit detection means 50, 51 to be transmitted to the external device 71 by one-way transmission. And a connector, a photocoupler and the like. The abnormality information external output means 70 can transmit each abnormality information separately. The external device 71 receives game information from each of the pachinko machines in the game hall, and manages the game status of each of the pachinko machines and the like, and is constituted by a computer or the like.

  The ball detecting means 25, 26 are magnetically responsive non-contact switches. As shown in FIG. 7, the first ball detecting means 25 has an internal resistance or the like when the game ball passes through the through hole 61. It is changing. In the ball detecting means 25, 26, lead wires 62, 63 are connected directly to a pair of terminals 64, 65 or indirectly via a connector or the like. The lead wires 62 and 63 are connected to the integrated circuit device 46 via the connector 66 and the like of the main control board 36.

  The disconnection detecting means 48, 49 and the short-circuit detecting means 50, 51 are configured as shown in FIG. FIG. 7 illustrates only the first disconnection detecting means 48 and the first short-circuit detecting means 50 corresponding to the first ball detecting means 25, but the second disconnection detecting means 49 corresponding to the second ball detecting means 26. The second short-circuit detecting means 51 has the same configuration.

  The first ball detecting means 25 has one terminal 64 connected to a DC power supply (for example, +12 V) via a lead wire 62 and the other terminal 65 connected to a first disconnection detecting means 48 and a first short circuit via a lead wire 63. Each is connected to the detection means 50, and outputs a predetermined voltage (for example, + 5V) when a game ball is not detected, and outputs a detection voltage (for example, + 1V) lower than the predetermined voltage when a game ball is detected. The signals are inputted to the first disconnection detecting means 48 and the first short-circuit detecting means 50.

  The first disconnection detecting means 48 includes a first transistor 67 constituting a first switching element, and a determination unit 68 for detecting a game ball and determining disconnection based on the length of operation time of the first transistor 67. The first transistor 67 operates according to the level of the output of the first ball detection means 25 so that the first transistor 67 turns off when the output of the first ball detection means 25 is lower than the detection voltage and turns on when the output is higher than the detection voltage. The base is connected to the first sphere detecting means 25 so that the state changes, and the collector on the output side is connected to a DC power supply (for example, +5 V) and the determination unit 68.

  The determination unit 68 determines that a game ball has been detected when the H-level output time (operating time of the first transistor 67) t of the first transistor 67 is shorter than the predetermined time T as shown in FIG. Also, as shown in FIG. 8B, when the output time t is longer than the fixed time T, it is determined that the first ball detecting means 25 is disconnected. In this case, a disconnection signal is output.

  The predetermined time T of the determination unit 68 is set to a time that is necessary and sufficient for the passing of the game ball in consideration of the passing time when the game ball passes through the first ball detection unit 25. .

  The first short-circuit detecting means 50 includes a second transistor 69 constituting a second switching element, and an output transistor 70 which is turned on and off in reverse to the second transistor 69. The base of the second transistor 69 is connected to the first ball detecting means 25 via the Zener diode 71 so that the second transistor 69 is turned on when the output of the first ball detecting means 25 is higher than the detection voltage (short-circuit voltage). The collector on the output side is connected to a DC power supply (for example, +5 V) and the output transistor 70, and outputs a short-circuit signal via the output transistor 70 when the first ball detection means 25 is short-circuited. I have. The Zener voltage of the Zener diode 71 is set higher than the detection voltage when the first ball detection means 25 detects a game ball.

  In the above-mentioned ball game machine, when the firing handle 10 of the firing means 9 is operated in a game, the game balls of the upper plate 7 are supplied to the firing unit one by one in conjunction with the firing operation of the firing means 9, and the game balls are supplied. The ball is hit with a hammer and fired sequentially along the guide rail 11 toward the game board 4.

  After the game ball fired on the upper side of the game board 4 enters the game area 12 of the game board 4, it falls into the normal prize means 17 to 19 while falling along the board surface, or the normal symbol starting means. Falling downward while passing 13. When the ball detecting means 25, 26 of the normal symbol starting means 13 detects the passing of the game ball, the display symbol of the normal symbol display means 22 fluctuates. When the stop symbol after the change of the ordinary symbol display means 22 becomes a hit symbol, the opening / closing claw 23 of the special symbol start winning means 14 is opened for a certain period of time, and a game ball wins in the special symbol start winning means 14. Easier to do.

  When the special symbol starting winning means 14 detects a game ball, the display symbol of the special symbol display means 21 fluctuates for a certain period of time. If the display symbol after the stop of the special symbol display means 21 becomes a big hit symbol, the open / close plate 24 of the variable winning means 16 is opened to the front side, so that the game balls can easily win. Then, when a certain period of time has passed since the opening and closing of the opening and closing plate 24, or when the second ball detection means 26 detects a winning of a predetermined number of game balls, the opening and closing plate 24 closes. When the first ball detecting means 25 in the specific area detects a game ball which has won the variable winning means 16, the opening and closing plate 24 is opened again, and the same opening and closing operation is repeated up to 16 times.

  If, for example, a disconnection or short circuit occurs in the first ball detection means 25 during this game operation, the first disconnection detection means 48 and the first short circuit detection means 50 operate as follows to detect a disconnection or short circuit. . In normal times when the game ball does not pass, the first ball detecting means 25 outputs a predetermined voltage (+5 V), the first transistor 67 of the first disconnection detecting means 48 is turned on, and the output remains at the L level. . Therefore, the determination unit 68 does not output any of the detection signal and the disconnection signal. Since the Zener diode 71 does not conduct, the first short-circuit detecting means 50 does not output a short-circuit signal while the second transistor 69 remains off.

  When the first ball detecting means 25 detects a game ball, the output of the first ball detecting means 25 decreases to about +1 V which is equal to or lower than the predetermined voltage. Therefore, the first transistor 67 of the first disconnection detecting means 48 is turned off, and the output of the first transistor 67 becomes H level.

  However, as shown in FIG. 8A, the output of the first disconnection detecting means 48 is maintained at the H level only while the game ball passes through the first ball detection means 25, and when the game ball has passed, the output of the first disconnection detection means 48 is terminated. One transistor 67 is turned off and its output goes to L level. As a result, the first transistor 67 is turned off within the predetermined time T, so that the determination unit 68 determines that a game ball has been detected, and does not determine that the first ball detection unit 25 is disconnected.

  Note that the first short-circuit detecting means 50 does not output the short-circuit signal because the Zener diode 71 does not conduct similarly to the above, and the second transistor 69 remains off.

  When the disconnection of the connector 66, the lead wires 62, 63, etc. occurs on the first ball detecting means 25 side, the output of the first ball detecting means 25 decreases to 0V, so that the first transistor 67 of the first wire detecting means 48 is turned on. The output is turned off, and the output becomes H level as in the case of detecting a game ball.

  However, in the case of a disconnection, as shown in FIG. 8B, unlike the case of detecting a game ball, the first transistor 67 does not turn on even after a certain period of time T has elapsed. The disconnection is determined based on the lapse of time T, and the disconnection signal is output. It goes without saying that the first short-circuit detecting means 50 does not output a short-circuit signal.

  When a short circuit occurs in the connector 66, the lead wires 62, 63, etc. of the first ball detecting means 25, the output of the first ball detecting means 25 becomes 12V. For this reason, the Zener diode 71 of the first short-circuit detecting means 50 conducts, the second transistor 69 turns on, the output transistor 70 turns off, and its output becomes H level, and a short-circuit signal is output. On the other hand, since the first transistor 67 of the first disconnection detecting means 48 maintains the ON state as in the normal state, the first disconnection detecting means 48 does not output a disconnection signal.

  If the first disconnection detecting means 48 and the first short-circuit detecting means 50 having such a configuration are used, the disconnection and the short-circuit on the first ball detecting means 25 side are separately performed by the change of the output voltage of the first ball detecting means 25. It can be detected and its configuration can be simplified. Moreover, in the first disconnection detecting means 48, the determination unit 68 determines that the game ball is detected when the time t when the output of the first transistor 67 is at the H level is shorter than the predetermined time T, and determines that the disconnection occurs when the time is long. Since the determination is made, the detection of the game ball and the disconnection of the game ball are facilitated in spite of the configuration that the first transistor 67 is turned on when the output of the first ball detection means 25 is lower than the predetermined voltage. Can be distinguished.

  When the first ball detecting means 25 detects a game ball, a detection signal of the first ball detecting means 25 is output after a lapse of a predetermined time T set in the determination section 68, and the detection signal is output. Various game controls may be performed on the basis of the game control. Further, the detection signal of the first ball detecting means 25 may be output from the determination section 68 of the first disconnection detecting means 48 after a lapse of a predetermined time T.

  When the first disconnection detecting means 48 detects the disconnection of the first ball detecting means 25, both the display sections 55 and 56 of the first notification means 20 display "1" by the notification control of the notification control section 54, The illuminant 57 of the second notification means 47 emits light to display and notify. When the first short-circuit detecting means 50 detects the short-circuit of the first ball detecting means 25, the notification control of the notification control section 54 causes the display section 55 of the first notification section 20 to display "1" and the display section 56 to display "2". Are displayed, and the luminous body 58 of the second notification means 47 displays and notifies the user. The same applies to the case where the second disconnection detecting means 49 and the second short-circuit detecting means 51 detect the disconnection and short-circuit of the second ball detecting means 26.

  In this manner, the disconnection or short circuit of the ball detecting means 25, 26 can be easily reported to the player, the manager, or the like by the reporting of the reporting means 20, 47. In particular, if the display of "1" or "2" on each of the display portions 55 and 56 of the first notification means 20 is viewed, even if the front frame 3 of the ball game machine main body 1 is not opened, it is possible to detect a ball in which an abnormality has occurred. The cause of the abnormality of the means 25, 26 and the ball detecting means 25, 26, that is, disconnection or short circuit can be easily grasped.

  In addition, if a disconnection or short circuit occurs on the ball detecting means 25, 26 side, the front frame 3 is opened and the condition of the lead wires 62, 63, the connector 66, etc. is checked from the back side, and then necessary. In this case, the main control board 36 in the main control board case 37 has the second notification means 47, and the luminous bodies 57 to 60 of the second notification means 47 are also provided. Since the light-emitting display indicates the sphere detecting means 25 and 26 in which the abnormality has occurred and the cause of the abnormality, inspection and repair of the sphere detecting means 25 and 26 can be easily performed.

  Furthermore, since the disconnection detecting means 48, 49 and the short-circuit detecting means 50, 51 are provided in a single integrated circuit device 46, compared with a case where the components are combined with electric components such as transistors without being integrated circuits. In addition, the whole can be reduced in size, and the disconnection detecting means 48, 49 and the short-circuit detecting means 50, 51 can be easily mounted on the main control board 36.

  FIG. 9 exemplifies a second embodiment of the present invention, in which the disconnection detecting means 48, 49 are divided into a judging section 68 and switching circuits 48a, 49a including a first transistor 67 and the like preceding the judging section 68. The switching circuits 48a, 49a are provided in the integrated circuit device 46 together with the short-circuit detecting means 50, 51 and the like, and the judging section 68 is provided in the main control means 45. That is, the disconnection detecting means 48, 49 are divided into switching circuits 48a, 49a and a determining unit 68, the switching circuits 48a, 49a are provided in a single integrated circuit device 46, and the determining unit 68 is provided in the main control unit 45. I have.

  In this case, the H level and L level signals of the first transistor 67 are sent to the determination unit 68 of the main control unit 45 via the I / O port 52, and the determination unit 68 detects the detection of the game ball and the disconnection. May be determined. Therefore, even with this configuration, the same effect as that of the first embodiment can be obtained.

  According to such an embodiment, the first abnormality detecting means 48, 49 for detecting the first electrical abnormality on the game medium detecting means 25, 26 side and the second electrical abnormality detecting means on the game medium detecting means 25, 26 side. Since the second abnormality detecting means 50 and 51 for detecting the target abnormality are separately provided, the abnormality on the game medium detecting means 25 and 26 side can be detected, and the contents of the abnormality are the first electrical abnormality and the second electrical abnormality. It can be easily determined which of the above is an electrical abnormality.

  Further, since the abnormality detecting means 48, 49, 50, 51 capable of distinguishing and detecting the first electrical abnormality and the second electrical abnormality are provided, the content of the abnormality is the first electrical abnormality and the second electrical abnormality. It is possible to easily determine which one is an electrical abnormality. Further, since the first abnormality detecting means 48, 49 and the second abnormality detecting means 50, 51 are provided in a single integrated circuit device 46, the whole can be reduced in size and easily mounted on the control board 36 or the like. it can.

  Further, first abnormality notification means 20, 57, 59 for performing first abnormality notification on condition that the first abnormality detection means 48, 49 detect the first electrical abnormality, and second abnormality detection means 50, 51 Is provided with the second abnormality notification means 20, 58, 60 for performing the second abnormality notification on condition that the second electrical abnormality is detected, so that the first electrical abnormality and the second electrical abnormality are detected. Abnormalities can be notified separately. Since the first abnormality detecting means is the disconnection detecting means 48, 49 and the second abnormality detecting means is the short circuit detecting means 50, 51, the disconnection and the short circuit of the game medium detecting means 25, 26 can be separately detected.

  Further, the game medium detecting means 25, 26 has a function of outputting a predetermined voltage when the passage of the game medium is not detected, and outputting a detection voltage lower than the predetermined voltage when detecting the passage of the game medium, The first abnormality detecting means 48, 49 comprises: a first switching element 67 whose operation state changes when the output of the game medium detecting means 25, 26 is lower than the detection voltage and higher than the detection voltage; A determination unit 68 that determines that a disconnection has occurred and outputs a disconnection signal when the operation time of the first switching element 67 is longer than a predetermined time T when the outputs of the means 25 and 26 are equal to or lower than the detection voltage; The detecting means 50 and 51 are provided with the second switching element 69 which operates when the output of the game medium detecting means 25 and 26 is higher than the detection voltage and outputs a short-circuit signal. As well as normal game media detection and gaming A disconnection of the body detecting means 25 and 26 side can be reliably distinguished.

  Since the abnormality information of the first electrical abnormality and the second electrical abnormality can be transmitted to the external device 71, the external device 71 can also grasp and manage the abnormality information.

  As described above, the embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments. For example, in each embodiment, the case of detecting a disconnection or a short circuit on the ball detecting means 25, 26 side of the variable winning means 16 is illustrated, but other ordinary symbol starting means 13 and winning means 14 on the gaming board 4 side. , 16, 17 to 19 can be implemented similarly in the case of disconnection or short circuit on the ball detecting means side. In the case where a ball detecting means 34 for detecting a game ball paid out by the ball payout means 31 and / or a game ball paid out is provided on the entrance side and / or the exit side of the ball payout means 31, the ball detection is performed. The same can be applied to a disconnection or short circuit on the means 34 side.

  In the embodiment, the switching elements of the disconnection detecting means 48, 49 and the short-circuit detecting means 50, 51 are constituted by the transistors 67, 69, but various switching elements other than the transistors may be used. Further, instead of the Zener diode 71 of the short-circuit detecting means 50, 51, a switching element such as a diac having a function of turning on at a voltage higher than a certain level may be used.

  In the embodiment, the disconnection detecting means 48 and 49 are exemplified as the first abnormality detecting means, and the short-circuit detecting means 50 and 51 are exemplified as the second abnormality detecting means. In addition to the above, various electrical abnormalities that may occur on the sphere detecting means 25 and 26 may be detected. Therefore, the cause of the abnormality is not limited to disconnection and short circuit. In addition, the ball detecting means 25 and 26 can be formed by a movable contact switch or the like in addition to a static contactless switch such as a magnetically responsive type.

  Although the first notifying means 20 serves both as the disconnection notifying means and the short-circuit notifying means, the disconnection notifying means and the short-circuit notifying means may be provided separately. In the case of adopting, it is sufficient to provide it at any one of the front sides of the ball and ball game machine main body 1. It is sufficient that the second notification means 47 is provided at a location on the back side of the ball game machine main body 1 where it can be easily checked at the time of inspection or the like. Further, as the abnormality notification means, a voice type may be employed instead of the first notification means 20 and the second notification means 47. Further, the visual notification means and the auditory notification means may be used together.

  Further, in the embodiment, the ball detecting means 25 and 26 of the pachinko machine are illustrated as the game medium detecting means. However, the game medium is not limited to the ball game machine such as the pachinko machine, the arrange ball machine, and the sparrow ball game machine. The present invention is also applicable to a spinning-type gaming machine using coins and the like, for detecting an abnormality on the game medium detecting means side such as the coin detecting means.
