The firing motor drive control means 705 is composed of a logic unit and a first drive circuit 654. The number-of-fired display means 707 is provided by the number-of-fired display device 20 and the third drive circuit 656, the notification signal output means 704 is provided by the second drive circuit 655 and the amplifier 696, and the touch detection means 706 is provided by a touch detection circuit. 651.

Hereinafter, a specific operation of the hit ball firing control by the control block will be described.

In the above control block, while the timer unit 702 (corresponding to a crystal oscillator and a logic unit) counts a predetermined time (1 minute) as a predetermined specified period, the pulse generation number generated from the motor sensor 490 is counted. 701 (corresponding to a logic part) counts to obtain the number of rotations per fixed time (one minute). The rotation speed per fixed time obtained in this way is sent to the number-of-firings display means (firing-number display device) 20 and the comparing means 703 (corresponding to a logic unit). Of these, the number-of-firings display means 20 is
On the basis of the signal from 701, the obtained number of rotations per fixed time is displayed on a numerical display.
Further, the comparing means 703 compares a predetermined number (100 times) as a predetermined specified number stored therein with the rotation speed. As a result of this comparison,
When the comparing means 703 determines that the number of revolutions (number of shots) per predetermined time is equal to or more than a predetermined number (100 / min), the comparing means 703 outputs a notification signal output means 704.
(Corresponding to the second drive circuit and amplifier), an ON signal is output,
Upon receiving the ON signal, the notification signal output means 704 sends an unauthorized signal to the lamp 698 and the speaker 695 serving as the notification means to notify a player or the like by the notification means that the firing motor 439 is being illegally driven. It has become.

The notification signal output means 704 has a reset switch 2
10 is connected, and when the reset switch 210 is pressed and an ON signal is output to the notification signal means 704, the notification of fraud by the notification means (lamp, speaker) is stopped.

Also, a drive signal is output to the firing motor 439 to
The firing motor drive control means 705 (corresponding to the first drive circuit of the logic unit) for controlling the operation of the camera is provided with various switches for detecting whether or not a condition for starting the operation of the firing motor 439 is satisfied, that is, firing. The touch sensor 250 is connected via the switch 160, the overflow switch 220, and the touch detection means 706.

The firing motor drive control means 705 outputs an ON signal from the firing switch 160 based on output signals from the three switches (sensors), and outputs an ON signal from the touch detection means 706. When all three conditions that the ON signal (overflow signal) is not output from the overflow switch 220 are satisfied, a drive signal is output to the firing motor 439.

Further, the above-mentioned comparison means 703 is connected to the firing motor drive control means 705, and a signal indicating that the number of rotations (the number of firings) of the motor 439 per predetermined time is equal to or more than a predetermined number of times (100 / min). When input from the comparing means 703 to the firing motor drive control means 705, the means 705
The rotation of the is stopped.

Further, the timer means 702 is connected to the firing motor drive control means 705, and the timer means 702 detects that a drive signal for driving the firing motor 439 is output from the fire motor drive control means 705. It is determined that the launching motor 439 is rotating, and a predetermined time is measured only under this condition. Then, when the counting is started and when the counting for the predetermined time is completed, the counting means 701 is used.
Then, a signal indicating that a time interval (unit time) for counting the number of revolutions (number of shots) of the firing motor 439 has elapsed is output.

In the present embodiment, the number of rotations of the firing motor 439 is calculated by counting the number of pulses from the motor sensor 490 generated while the counter means is counting a predetermined time (for example, one minute). The present invention is not limited to this. For example, the pulse generation interval from the motor sensor 490 may be counted, and the number of revolutions may be calculated based on the reciprocal. The hitting ball launching device may be of any type as long as it launches a game ball into a game area.

In the present embodiment, the firing motor 439 per fixed time is used.
The number of rotations was detected and this was regarded as the number of hit balls fired per fixed time.However, a sensor was installed in the path of the game ball that was fired, and the actually shot game ball was directly detected, and The number of shots per hour may be determined.

Further, in the present embodiment, the timer means is a crystal oscillator which is not affected by a change in the power supply voltage (change in frequency) supplied to the island facilities of the game arcade.
1 minute) is always measured accurately, but various timer means such as a clock pulse oscillator having a unique power supply can be used as a timer means which is not affected by a change in the power supply voltage of the island facility. It can be used.

[Effect of the Invention] According to the present invention, the number of shots of a game ball during a predetermined period is counted by the firing number counting means, and when the counted number of shots is equal to or more than the predetermined number. In this case, it is determined by the number-of-firings determining means that the number has exceeded the specified number. Then, a judgment signal is output from the number-of-shots judging means, and the hitting ball firing device is deactivated by the firing deactivating means based on the judgment signal.

As a result, for example, when the game store performs fraud to increase the number of shots per unit time by the hit ball firing device,
Since the hitting ball launching device is deactivated and the game cannot be played, a sound ball game machine capable of reliably preventing fraud that increases the number of firings per unit time can be provided.

In addition, based on a determination signal from the number-of-firings determining means, a notifying means for recognizing that the number of firings is equal to or greater than a predetermined number is provided so that it is notified that the illegal operation has been performed. It is notified by means, and it is possible to reliably prevent fraud.
