  The present invention has been made in view of the above points, and an object of the present invention is to provide a gaming machine that can easily find that an unauthorized main board is attached.

The gaming machine of the present invention is a gaming machine comprising a main board and a sub board, and a power feeding time measuring means for measuring a power feeding time from turning on the power of the gaming machine to turning off the power on the main board and the sub board, respectively. A power supply time measurement value storage means for storing a power supply time measurement value measured by the power supply time measurement means when the power is shut off, and the main board supplies power supply time measurement value storage means for the main board when the power is turned on again. The power supply time measurement value stored in the sub board is output to the sub board, and the sub board stores the power supply time measurement value input from the main board and the power supply time measurement value of the sub board when the power is turned on again. The power feeding time measurement value stored in the means is compared, and notification is given when there is a deviation between the two power feeding time measurement values.

  In the gaming machine of the present invention, when a fraudulent act is performed between power-on and power-off, and a legitimate main board is removed and a fraudulent main board is attached, the power feeding time measuring means of the sub board measures There is a discrepancy between the power supply time measurement value and the power supply time measurement value measured by the unauthorized power supply time measurement means of the main board. For this reason, when the power is turned on again, the power supply time measurement value on the main board side and the power supply time measurement value on the sub board side are compared, and there is a gap between the two, making it easy for fraudulent activity to be performed. To be able to discover.

  Here, even when there is no deviation between the two power feeding time measurement values, the notification is made when the power feeding time measurement value is smaller than a predetermined value. A fraudulent act is performed at night when the power supply of the gaming machine is cut off, and after attaching the illegal main board, turning off the power and shutting off after a short time causes a gap between the two power feeding time measurements An operation to prevent it from occurring can be considered. However, by detecting that the power feeding time measurement value is smaller than the predetermined value, it is possible to easily find the unauthorized operation as described above.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram of the main part of an electric system in a pachinko gaming machine according to an embodiment of the present invention, and FIG. 2 shows the contents of processing for fraud detection by the main control board and the production control board shown in FIG. The flowchart shown in FIG. 3 and FIG. 3 show timing charts for comparing and explaining the operation patterns at the time of normal operation and the occurrence of fraud.

  In FIG. 1, 1 is a main control board as a main board incorporating a program for controlling the entire gaming state, 2 receives a command from the main board 1, a symbol variation display by the symbol display device 3, and a sound by the speaker 4. This is an effect control board as a sub board for controlling output and lamp display by the decoration lamp 5 respectively, and represents an effect control board connected to the external device 6 around the gaming machine.

  The main control board 1 is activated when the gaming machine is powered on, and stores a power feeding time measuring unit 11 that measures a power feeding time until the power is shut off, and a power feeding time measurement value measured by the power feeding time measuring unit 11 when the power is shut off. Power supply time measurement value storage means 12 is provided.

  The effect control board 2 is measured by the power feeding time measuring means 21 that starts when the gaming machine is turned on and measures the power feeding time until the power is turned off, and the power feeding time measuring means 21 when the power is turned off, like the main control board 1. Power supply time measurement value storage means 22 for storing the power supply time measurement value. Further, the effect control board 2 stores the previous power supply time measurement value stored in the power supply time measurement value storage means 12 of the main control board 1 and the power supply time measurement value storage means 22 of the effect control board 2 when the power is turned on again. Comparing / determining means 23 is provided for comparing the stored power supply time measurement value in the previous time and determining whether or not an unauthorized act of replacing the main control board 1 with an unauthorized main control board has been performed. When the comparison determination unit 23 determines that an illegal act has been performed, the decorative lamp 5 indicates that the main control board 1 is an illegal main control board by displaying an image on the symbol display device 3 and outputting sound by the speaker 4. Informs by lamp display. Further, the comparison / determination means 23 outputs a signal indicating that the main control board 1 is an unauthorized main control board to the external device 6 such as a hall computer. Here, the image display by the symbol display device 3 may display the power feeding time measurement values of the main control board 1 and the effect control board 2 in numbers.

  Next, based on the flowchart of FIG. 2, a flow of processing for discovering fraud by the main control board 1 and the effect control board 2 will be described.

  When the power of the gaming machine is turned on, both the main control board 1 and the effect control board 2 start measuring the power feeding time (steps S1, S11).

  Next, the main control board 1 determines whether or not there is a previous power supply time measurement value (step S2), and if there is a previous power supply time measurement value, transmits this power supply time measurement value to the effect control board. (Step S3) On the other hand, when there is no previous power feeding time measurement value, the fact that the backup data is abnormal is transmitted to the effect control board 2 (Step S4). Here, the previous power feeding time measurement value is the power feeding time measurement value stored in step S6, which will be described later, at the time of the previous power shutdown.

  On the other hand, the effect control board 2 determines whether or not there is a previous power feeding time measurement value (step S12), and is performed when there is a previous power feeding time measurement value, from the main control board 1 to the previous power feeding time measurement value. (Step S13), when the previous power feeding time measurement value is received from the main control board 1, the previous power feeding time measurement value on the effect control board 2 side and the main control board 1 side Whether or not there is a deviation (for example, 3 seconds) between the previous power feeding time measurement value and the previous power feeding performed when there is no deviation between the previous power feeding time measurement values. It is determined whether or not the time measurement value is smaller than the predetermined value (step S15). If there is no previous power supply time measurement value or if the previous power supply time measurement value has not been received, the previous power supply time measurement value is determined. If there is a gap between them, or the previous power feeding time measurement value is predetermined If less than, and outputs a signal indicating that the abnormality is present in the backup data to an external device 6 (step S16). Here, the previous power feeding time measurement value is the power feeding time measurement value stored in step S18, which will be described later, when the power was last turned on. The previous power supply time measurement value received from the main control board 1 is the previous power supply time measurement value transmitted from the main control board 1 to the effect control board 2 in step S3.

  After that, when the power is cut off, both the main control board 1 and the production control board 2 determine the voltage drop due to the power cut off (steps S5 and S17), and the power feeding time measured value from the current power on to the power cut off Is stored (steps S6 and S18).

  In FIG. 3, (A) is when cheating is not performed, (B) is when cheating is performed during power feeding, and (C) is when cheating is performed while power feeding is stopped. Correspond to each.

  As shown in FIG. 3 (A), when a fraudulent act is not performed, the power feeding time measurement value measured on the main control board 1 and the power feeding time measurement value measured on the effect control board 2 match each other. An abnormal signal is not output when the power is turned on again.

  As shown in FIG. 3 (B), when an illegal act is performed during power feeding, the power feeding time measurement value measured by the unauthorized main control board 1 and the effect control board 2 are measured when the power is turned on again. It is determined that there is a difference between the measured power supply time and an abnormal signal is output.

  As shown in FIG. 3 (C), when an illegal act is performed while power feeding is stopped and an operation for turning on the power for a short time is performed, the power feeding time measurement value is smaller than a predetermined value when the power is turned on again. Is determined, an abnormal signal is output, and the power feeding time measurement value is displayed on the symbol display device 3.
