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 or the like.
The other terminal 65 is connected to the first disconnection detecting means 48 via the lead wire 63.
And a first short-circuit detecting means 50, which 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. Then, it is 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 judging section 68 for detecting a game ball and judging a disconnection based on the length of operation time of the first transistor 67. ing. First transistor 67
Is turned off when the output of the first ball detecting means 25 is lower than the detection voltage, and turned on when the output is higher than the detection voltage.

It is connected to the.

The judging section 68, as shown in FIG.
When the H-level output time (the operation time of the first transistor 67) t of the transistor 67 is shorter than the fixed time T, it is determined that a game ball has been detected, and the output time t is fixed as shown in FIG. When the time is longer than the time T, it is determined that the first ball detecting means 25 is disconnected, and after the determination, a ball detection signal is output in the former case and a disconnection signal is output in the latter case.

It is to be noted that the predetermined time T of the determination section 68 is set to a time necessary and sufficient for the passing of the game ball in consideration of the passing time when the game ball passes the first ball detecting means 25. Have been.

The first short-circuit detecting means 50 includes a second transistor 69 constituting a second switching element, and an output transistor which is turned on and off in reverse to the second transistor 69.
70 and. 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. When the first ball detecting means 25 is short-circuited, a short-circuit signal is output via the output transistor 70. I have. The Zener voltage of the Zener diode 71 is set higher than the detection voltage when the first ball detecting 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 during 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. Hit the game ball with a hammer and guide rail 11
Are sequentially fired to the game board 4 side along.

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 on the normal prize means 17 to 19 while falling along the board surface, or It falls downward while passing through the symbol starting means 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 prize means 14 is opened for a certain period of time, and a game ball wins the special symbol start prize 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 predetermined time. If the display symbol after the stop of the special symbol display means 21 becomes a big hit symbol, the opening and closing 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. Also, the first ball detecting means 25 in the specific area is changed to the variable winning means 16.
Is detected, the open / close plate 24 is opened again, and the same opening / closing operation is repeated up to 16 times.

During this game operation, for example, the first ball detecting means 25
If a disconnection or short circuit occurs in the first, the first disconnection detecting means 48,
The first short detection means 50 operates as follows to detect a disconnection or a 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. First short-circuit detecting means 50
Since the Zener diode 71 does not conduct, the second transistor 69 remains off and does not output a short circuit signal.

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

However, as shown in FIG. 8A, only when the game ball passes through the first ball detecting means 25, the first disconnection detecting means is used.
When the output of 48 maintains the H level and the game ball has passed, the first transistor 67 is turned off and its output goes to the L level. As a result, the first transistor 67 is turned on for a certain time T.
To be turned off, the determination unit 68 determines that a game ball has been detected,
It is not determined that the first ball detecting means 25 is disconnected.

The first short-circuit detecting means 50 does not output a short-circuit signal because the Zener diode 71 does not conduct similarly to the above, so that 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.
The transistor 67 is turned off, and its output goes to the H level as in the case of detecting a game ball.

However, in the case of a disconnection, as shown in FIG. 8B, the first transistor 67 does not turn on even after a certain time T elapses, unlike the case of detecting a game ball.
68 determines that a disconnection has occurred after the lapse of the predetermined time T, and outputs a disconnection signal. 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. As a result, 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, the output goes to H level, and a short-circuit signal is output. On the other hand, the first transistor 67 of the first disconnection detecting means 48 maintains the ON state as in the normal state, so that 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 short-circuit on the first ball detecting means 25 side are caused by the change of the output voltage of the first ball detecting means 25. Can be detected separately, and the configuration can be simplified. Moreover, in the first disconnection detecting means 48, the determination unit 68 determines that the game ball has been 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 has occurred 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 judging section 68, and What is necessary is just to perform various game control based on a detection signal. Further, the detection signal of the first ball detection means 25 may be output from the determination section 68 of the first disconnection detection means 48 after a predetermined time T has elapsed.

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 notifying means 20 display "1" by the notification control of the notification control section 54. At the same time, the luminous body 57 of the second notification means 47 emits light to display a notification. When the first short-circuit detecting means 50 detects a short-circuit of the first ball detecting means 25, the notification control of the notification control section 54 causes the first short-circuit detecting means 50 to perform the first
The display unit 55 of the notification unit 20 displays “1” and the display unit 56 displays “2”, and the luminous body 58 of the second notification unit 47 emits light to notify. 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.

As described above, the breaking of the ball detecting means 25, 26 and the short circuit can be easily notified to the player, the manager, and the like by the notification of each of the notifying means 20, 47. In particular, each display section 55,5 of the first notification means 20
If you look at the display of “1” or “2” in 6
Even if the front frame 3 of 1 is not opened, the sphere detecting means 25, 26 in which the abnormality has occurred and the cause of the abnormality of the sphere detecting means 25, 26, that is,
It can be easily grasped whether a disconnection or a short circuit occurs.

Further, if a disconnection or short circuit occurs on the ball detecting means 25, 26 side, the front frame 3 is opened and the status of the lead wires 62, 63, the connector 66, etc. is checked from the back side. ,
If necessary, repair such as replacement is performed. In this case, too, the main control board 36 in the main control board case 37 has the second notifying means 47, and the luminous body 57 of the second notifying means 47 is provided. The sphere detection means 25, 26 in which the abnormality has occurred and the cause of the abnormality are displayed by the light emission display of ~ 60.
Inspection and repair of 6 can be easily performed.

Further, disconnection detecting means 48 and 49, short-circuit detecting means 5
0,51 are provided in a single integrated circuit device 46, so that the whole can be reduced in size as compared with the case where electric components such as transistors are combined without being integrated, and the disconnection detecting means is provided. 48, 49 and the short-circuit detecting means 50, 51 can be easily mounted on the main control board 36.
