As disclosed in Japanese Patent No. 5379, a plurality of rotating members are rotatably supported by a drive shaft driven by one motor through a sliding friction mechanism, and each of them corresponds to a ratchet gear formed on a side surface of each rotating member. The rotation drive control / stop control is performed by engaging and disengaging the solenoid that is provided. Then, the determination of the combination of the identification information (also referred to as a pattern) in these rotating members is provided on the other side by the light emitted from the plurality of projectors provided on one side of the storage box for storing the plurality of rotating members. Light is received by a plurality of corresponding light receivers, and a combination of identification information displayed to the player is determined by the combination of the received light receivers.

[0003]

Therefore, as the combination of the identification information, a combination in which all the light receivers do not receive light at all, a combination in which all the light receivers receive light, or an arbitrary number of light reception Since there are various combinations such as combinations in which the projector receives light, for example, when the projector or receiver fails, or when the motor fails, those failures cannot be known by the projector and receiver. However, there are cases where a trouble such as not determining a big hit occurs even though the combination of the identification information is in the specific display mode. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ball game machine that can easily and quickly know when a failure of a variable display device occurs.

[0004]

In order to achieve the above object, in the present invention, in a ball game machine provided with a variable display device, the variable display device is a rotation in which a plurality of pieces of identification information are drawn. A drive control means for driving and controlling the variable display device displays the predetermined identification information by driving the motor when the power is turned on, while the drive control means includes a member and a motor for rotating the rotating member. It is characterized in that it includes initial drive control means for stopping at this time.

With this configuration, when the ball game machine is turned on one after another at the start of business, etc., and when the predetermined identification information is not displayed on the display unit of the variable display device thereafter. Immediately, it is found that the variable display device is out of order.

Further, the motor comprises a stepping motor, and the variable display device further monitors a rotational movement of the rotating member and resets a step counter for counting the number of step signals for driving the stepping motor. An abnormality determination that determines that the drive control means is abnormal when the detection signal from the sensor is not sent to the drive control means for a certain period of time or more while the step signal is being derived. The stepping signal is derived and the stepping motor is driven by including the means and the informing means for informing that when the abnormality determination output from the abnormality determining means is derived. Despite the conditions,
When there is no signal from the sensor that monitors the rotational movement of the rotating member for a certain period of time, it means that either the stepping motor has failed or the sensor has failed. The failure of the display device can be easily and quickly detected, and there is no trouble with the player.

(3) Operation of Variable Display Device The operation of the variable display device 60 having the above structure will be described with reference to FIGS. 10 to 14. A stepping motor (SP motor) provided in the variable display device 60 will be described.
77a-77c and phototransistor (sensor) 98a
To 98c are input / output circuits (I / O) as shown in FIG.
It is connected to the microcomputer 130 via 134. The microcomputer 130 includes an MPU 131 capable of executing a control operation in a predetermined procedure and an MPU 131.
ROM 13 for storing operation program data of U131
2 and RA that can write and read necessary data
And M133. Further, the start switch 1 is connected to the microcomputer 130 via the input / output circuit 134.
6a to 16c, stop switch 9, variable winning ball device 110
Solenoid 114, and a specific winning area 120 described later
The V winning ball detectors (V sensors) 122 provided in the above are respectively connected. It should be noted that instead of the stop switch 9, a stop signal may be issued by a timer that measures a fixed time.

By the way, when the power is turned on, the variable display device 60 performs the operation shown in FIG. That is, it is determined whether or not the power is turned on (step S
1) When turned on, all the stepping motors 77a to 77c (hereinafter referred to as SP1 to 3 motors) are started to drive (steps S2, S2 ', S2 "). Because
The processing for the SP1 motor will be described.

When the SP1 motor is driven in step S2, it is determined whether or not the value of the step counter SC1 provided in the microcomputer 130 is the reset value (step S3). By the way, the stepping motor is rotated by repeatedly sending four step signals as shown in FIG. That is, the signal of (1100) is used in step 1, and the signal of (011) is used in step 2.
0) signal, (0011) signal in step 3, and (1001) signal in step 4
Since the signal of the step rotates by 3.75 degrees,
The SP motors 1 to 3 rotate once by the signal of 96 steps. Therefore, if the number of identification information drawn on the rotary drums 76a to 76c is 12, for example, 1
An 8-step signal is sent to move one identification. Therefore, the step counter SC1 detects the reset value of step 1 every time there is a signal of 4 steps. Therefore, the reset value in step S3 is the same as the step 1 (11)
00) is indicated.

When the step counter SC1 detects the reset value in step S3, it is determined whether or not the sensor 1 (phototransistor 98a) is ON (step S).
4). This is determined to be ON when the sensor 1 detects the cutout portion 89a. If the sensor 1 is not determined to be ON even after the elapse of the fixed time T (step S6), an alarm process is performed (step S7) to issue an alarm. This is because the SP1 motor may be defective or the sensor 1 may be defective.

On the other hand, when the sensor 1 is turned on, the step number n1 of the display data corresponding to the identification information to be displayed on the rotary drum 76a is called (step S
5) After that, it is judged whether or not the value of the step counter SC1 and the number of steps n1 of the display data are the same (step S8), and when they are the same, the SP1 motor is stopped (step S9), and it is determined in advance. The defined identification information is displayed.

Steps S3 to S of the above SP1 motor
The process of 9 is also applied to the processes of steps S3 'to S9' and steps S3 "to S9" of the SP2 motor and the SP3 motor, and the predetermined identification information is displayed on the rotary drums 76b and 76c.

As described above, in this embodiment, when the power is turned on, the stepping motors 77a to 77c are unconditionally supplied.
Is rotated to display predetermined identification information and stop. Therefore, it is possible to determine the defect of the variable display device 60 before the player starts the game.

Next, the operation of the variable display device 60 during the game will be described with reference to FIG. First, a ball hits the start winning openings 15a to 15c, and the start switches 16a to 1
It is determined whether or not 6c is turned on (step S1
0), when turned on, the data RD1 to RD3 randomly picked up are confirmed (steps S11 and S1).
1 ', S11 "). These data RD1 to RD3 are SP
1 to SP3 motors respectively. The data RD1 to RD3 are also data for specifying the identification information displayed on the rotary drums 76a to 76c. For this reason, in this operation embodiment, the starting winning opening 15a ...
At the time when a hit ball is won in 15c, the rotating drums 76a to 7
The combination of the identification information displayed on 6c will be determined.

Since the following processing is the same for each SP motor, the processing procedure for the SP1 motor will be described. After the data RD1 is confirmed, the SP1 motor is driven (step S12). When the SP1 motor is driven, as shown in FIG. 14, a signal with a large pulse width is given first, and then a signal with a small pulse width is gradually given so as to gradually increase the rotation speed. this is,
This is done because the starting torque of the SP1 motor is small. Also, when the SP1 motor is stopped, it is preferable that the SP1 motor is stopped so that the rotation speed is gradually reduced. This is because, if suddenly stopped, the inertial force of the drum becomes larger than the magnetic attraction force, which may result in excessive rotation.

After the driving of the SP1 motor is started, it is judged whether or not the sensor 1 is turned on (step S13),
When turned on, the step counter SC1 is reset (step S14), and the step counter SC1 starts counting (step S15). The step counter SC1 is reset when the reset value is step 1 (1100) and the sensor 1 is turned on as shown in FIG. The length of the cutout portion 89a is determined so that the sensor 1 can accurately detect ON when the sensor 1 is in step 1 (1100). Explaining this, the stepping motor is rotating while repeating starting and stopping each time there is a signal of one step, and therefore is always rotating while shaking. Therefore, the notch 8
If the length of 9a is short, the sensor 1 detects a position where it is out of the cutout portion 89a due to blurring, and thus the step 1
Although it is (1100), the reset signal is not issued, and the identification information cannot be accurately determined. Therefore, the length of the cutout portion 89a is selected in consideration of the shake in the front-rear direction.

After the step counter SC1 starts counting,
It is determined whether or not there is a stop command signal from the stop switch 9 or the timer (step S16). When there is a stop command signal, it is determined whether or not the value of the step counter SC1 and the value of the data RD1 are the same. It is determined (step S17). Then, when the values become the same, the SP1 motor is stopped (step S18). At this time, the identification information displayed on the rotary drum 76a is the identification information determined corresponding to the data RD1.

The processing in steps S13 to S18 is performed in steps S13 'to SP2 and SP3 motors.
S18 'and steps S13 "to S18" are the same, and the data RD is stored in the rotary drums 76b and 76c.
2, the identification information corresponding to RD3 is displayed.

In the above embodiment, the identification information displayed when the start winning is won is determined.
After receiving the stop command signal, the stop position may be detected to determine the combination of the identification information. This can be determined by counting the number of steps from when the sensor detects the notches 89a to 89c to when the SP1 to SP3 motors stop.

(4) Variable Winning Ball Device Next, the configuration of the variable winning ball device will be described with reference to FIGS. 1 and 2. The variable winning ball device 110 has a mounting board 111 mounted on the game board 12, and a rectangular winning area 112 is formed on the mounting board 111.

Further, since the guide pieces 119a and 119b are provided at the positions corresponding to the guide pieces 115a and 115b, the specific winning area 120 is also located on the vertical line L. Therefore, in the illustrated embodiment, the specific winning area 120 and the starting winning opening 15a are 1
Since the player is formed on one vertical line L, the player aims to drop the ball at the center of the variable winning ball device 110, and the opening / closing plate 113 is closed.
The expectation of increasing the number of times of operation of the variable display device 60 is increased by increasing the number of operations of the variable display device 60, and while the opening / closing plate 113 is opened, it is possible to easily change the hitting ball into the specific winning area 120 without being disturbed. Re-opening (continuation) of the winning ball apparatus 110 is facilitated.

In other words, regardless of whether or not the variable winning ball device 110 is in operation, the player can play the variable winning ball device 110.
It suffices to aim at the central part of the and do not need to change the firing operation in the middle. Further, even in the specific game state, if the ball is shot aiming at the center of the variable winning ball device 110, the hitting ball is not interrupted and the specific winning area 120 is not disturbed.
