  As shown in the drawing, the corner member 28 has a groove 29 formed along the right edge, the upper edge, and the left edge. Accordingly, the groove 29 is formed at a position on the side and outside of the game area 13 (between the game area 13 and the outer periphery of the front frame 3) on the front frame 3 side holding the game board 4 provided with the corner members 28 and the like. Will be formed. A plurality of infrared sensors 30 are arranged in the groove 29. In this case, the infrared sensor 30 has a configuration of a reflective infrared sensor in which a light emitting unit 31 and a light receiving unit 32 are integrated side by side. The light emitting unit 31 can project infrared rays, and the light receiving unit 32 can receive reflected infrared rays. The light emitting means and the light receiving means described in the claims correspond to the light emitting section 31 and the light receiving section 32, respectively.

  An infrared light emitting diode is used as the light emitting element of the light emitting unit 31. A photodiode is used as the light receiving element of the light receiving unit 32. In this case, a phototransistor, a photo IC, or the like is applicable as the light receiving element of the light receiving unit 32. The infrared sensor 30 is mounted on a printed circuit board 33, and the infrared sensor 30 is arranged in the groove 29 by attaching the printed circuit board 33 to the groove 29 of the corner member 28. In this case, the printed circuit board 33 has a shape matching the groove 29, but may be divided into a plurality of parts.

  The infrared rays projected from the light emitting portion 31 of the infrared sensor 30 as shown in FIG. 6 and FIG. 7A which are BB sectional view and CC sectional view of FIG. The infrared rays are reflected by the reflecting portion 34 provided so as to be able to reflect the infrared rays toward the light receiving portion 32 at a position facing the groove portion 29, and the reflected infrared rays are received by the light receiving portion 32.

  The reflection portion 34 provided on the glass plate 26 is configured by a coating film in which a transparent infrared paint is applied to the surface of the glass plate 26. Since the glass plate 26 is disposed on the front side of the game area 13 and affects the visibility of the game area by the player, it is preferable to use the reflective portion 34 coated with such a transparent infrared paint. As such a transparent infrared paint, Eco Gold Super Clear (manufactured by Eco Gold) is used.

  In this case, since the distance between the reflecting part 34 and each infrared sensor 30 is configured to be constant, the infrared light receiving conditions by the light receiving part 32 of each infrared sensor 30 are the same, and the infrared sensor 30 Stable operation is performed. In addition, you may make it the structure which provided the reflection part 34 in the glass frame 27 holding the glass plate 26. FIG. Moreover, if the reflection part 34 is a place which can reflect the infrared rays projected from the infrared sensor 30 toward the light receiving part 32 of the infrared sensor 30 again, the frame side facing the frame side on which the infrared sensor 30 is provided.

At this time, the location where the light can be reflected varies depending on the directions of the light emitting unit 31 and the light receiving unit 32 of the infrared sensor 30 provided in the opposite frame.

  The light receiving unit 32 of the infrared sensor 30 is configured to always receive infrared rays, but cannot receive light when the infrared rays projected from the light emitting unit 31 are blocked by foreign matter or the like. In this case, as shown in FIG. 6 and FIG. 7A, in a state where the light receiving unit 32 receives infrared rays, the infrared sensor 30 is in an ON state, and in a state where the light receiving unit 32 does not receive infrared rays, The infrared sensor 30 is turned off.

  FIG. 7A shows the state of the infrared sensor 30 in the ON state, and FIG. 7B shows the state of the infrared sensor 30 in the OFF state. As shown in FIG. 7B, for example, a piano wire PW enters as a foreign object used for fraud from a gap 35 between the glass frame 6 and the front frame 3, and the glass plate 26 and the corner member. When the player tries to enter the game area 13 of the game board 4 through the gap 36 of the mating surface with the 28, the piano light PW prevents light reception by the light receiving unit 32 of the infrared sensor 30.

  The infrared sensor 30 is connected to the input / output circuit 42d of the main control board 42 as shown in the block diagram showing the configuration of the electric control of the gaming machine 1 in FIG. 8, and its ON state and OFF state are monitored. ing. The monitoring process of the infrared sensor 30 executed by the CPU 42a of the main control board 42 will be described using the flowcharts shown in FIGS. FIG. 9 is a flowchart showing main processing executed by the CPU 42a of the main control board 42.

  The CPU 42a of the main control board 42 performs main processing (S10 to S40) for executing a main program in which initial setting and the like are performed when the power is turned on. The loop process is repeated in the final process of the main process. While this loop processing is being performed, a timer interrupt occurs and interrupt processing (S50) is executed every 4 ms. In the initial setting (S10), stack setting, constant setting, CPU setting, SIO, PIO, CTC setting and the like are executed. It should be noted that the processing required only when the power is turned on is executed in the first round and not executed in the second and subsequent rounds, but the processing executed only in the first round is a well-known process, and details thereof Is omitted

  The interrupt inhibition (S20) prevents the interrupt processing from being performed until the interruption is permitted (S40) even if a timer interruption occurs every 4 ms. The special symbol main random number update process (S30) updates various random numbers. In the interrupt permission (S40), a timer interrupt is permitted every 4 ms.

  FIG. 10 is a flowchart showing the interrupt process (S50). The interrupt process (S50) includes the processes of S100 to S180. First, an output process (S100) for outputting an output command set in each process to various control boards is performed. Next, input processing (S110) is performed when various sensors attached to the gaming machine 1 detect signals.

  Next, the remaining time of the main process, that is, the normal symbol / special symbol main random number update process (S120) similar to the process performed in the loop process is performed. Then, a start winning opening switch detection process (S130) is performed. More specifically, in the input process (S110), when a winning signal is detected at the start winning opening 15 and a winning signal is detected, an addition is made when the number of each hold is less than four. A random value is acquired and stored in the corresponding RAM 42c.

  The next normal operation process (S140) is a normal symbol determination counter value update area in the RAM 42c when the normal symbol start sensor provided in the normal symbol variation start entrance 19 detects the passing of the game ball. The counter value (random number) is acquired from and stored in the acquisition area provided in the RAM 42c corresponding to the normal symbol variation starting entrance 19.

  Next, the special action process (S150) is performed after performing the special lose symbol creation process, and from the value of the special action status, any one of the special symbol standby process, the changing process, the special symbol confirmation process, and the special electric accessory process Process. Detailed descriptions of the special symbol standby process, the changing process, the special symbol confirmation process, and the special electric accessory process are omitted. The reserved ball number process (S160) reads the number of reserved balls stored in the RAM 42c, and sets the read reserved ball number data in the output buffer of the RAM 42c.

  In the infrared monitoring process (S170), it is determined whether the light receiving unit 32 of the infrared sensor 30 has received light (whether the output from the infrared sensor 30 is ON or OFF). FIG. 11 is a flowchart showing the infrared monitoring process (S170). If it is determined that the light receiving unit 32 of the infrared sensor 30 is receiving light (the output from the infrared sensor 30 is ON) as shown in the drawing (S200 (Yes)), this infrared monitoring process (S170) Exit. On the other hand, when it is determined that the light receiving unit 32 of the infrared sensor 30 is not receiving light (the output from the infrared sensor 30 is OFF) (S200 (No)), after performing notification (S210), infrared monitoring is performed. The process (S170) ends.

  As a specific configuration of the notification (S210) in this case, for example, there is sound output from the speaker 7 by the sound control board 43 and light emission of the decorative lamp 8 by the lamp control board 44. The infrared monitoring process (S170) by the main control board 42 described above corresponds to the monitoring means for monitoring the light receiving state of the light receiving means described in the claims.

  Thus, the foreign object such as the piano wire PW is detected from the gap 35 of the mating surface between the glass frame 6 and the front frame 3 before the foreign object enters the game area 13 without opening the glass frame 6 that is the opening / closing door. Therefore, such fraudulent acts can be prevented in advance.

  Further, since the infrared sensor 30 in which the light emitting unit 31 and the light receiving unit 32 used to detect a foreign object are integrated is provided in the groove 29 of the corner member 28 disposed outside the game area 13, the infrared sensor The infrared rays projected from the 30 light emitting units 31 are blocked by a game ball or the like flowing down the game area 13, or the projected infrared rays leak and are no longer projected in a predetermined direction. It is prevented that it falls.

  Further, as shown in FIG. 7A, the corner member 28 is formed with a glass plate receiving portion 37 that is in contact with the glass plate 26 higher than the outer peripheral portion of the corner member 28 at a position inside the groove portion 29. Yes. If the piano wire PW has entered the game area 13 without blocking the light received by the light receiving portion 32 of the infrared sensor 30, the glass plate receiving portion 37 receives the piano wire PW from the glass plate receiving portion 37. This is to prevent entry into the game area 13. By providing the glass plate receiving portion 37 in this way, it is possible to prevent the piano wire PW from entering the game area 13 in spite of the notification described above.
