Description

  The present invention relates to a lever operation detection device for a slot machine in which the detection timing is not always constant with respect to the operation timing of the start lever.

  In the slot machine, the game is started by operating the start lever, and at that time, the type of winning and the success or failure are determined by random number lottery. Since the result of the random number lottery has a periodicity, there is a tendency that the probability of winning is improved when the operation timing of the start lever is synchronized with a specific period. An illegal game exploiting this is an act of illegally improving a winning probability by operating a start lever using a solenoid or a low-frequency treatment device that generates pulsation.

As a measure to prevent the above illegal games, the control program can be changed so that the random number lottery cycle does not become constant. A method for preventing operation has been considered.

  However, the former preventive measure has a problem that the control program becomes complicated and leads to high costs in various aspects, and the latter preventive measure requires a long time because the operation of the start lever requires force. There is a problem of getting tired if you continue. An object of the present invention is to make it possible to prevent the detection timing from always being constant with respect to the operation timing of the start lever, and to achieve the prevention of fraudulent gaming without much cost.

In order to solve the above problems, the present invention has the following configuration. That is, the lever operation detecting device of the slot machine according to the present invention includes a light shield that swings in conjunction with the operation of the start lever, and an optical sensor in which a light emitting portion and a light receiving portion are arranged on both sides of the light shield. the combination will be, at the start lever operation detecting device of a slot machine to switch to a transmissive state and the cutoff state in response to the detection light swing position of the light shielding member to be irradiated toward the light receiving portion from the light emitting portion, said light shield, It includes a movable part that changes its position with respect to the shield body by an impact of lever operation.
The start lever operation detection device for a slot machine according to a second aspect of the present invention is the start lever operation detection device according to the first aspect, wherein the movable portion is structured to be fitted to the shield body. It is characterized by.
A start lever operation detection device for a slot machine according to a third aspect of the present invention is the start lever operation detection device according to the first or second aspect, wherein the shield body is integrated with a lever shaft of the start lever. It is formed in the shape of a thin shaft.

  With this configuration, each time the start lever is operated, the position of the movable portion with respect to the light shielding body is different, and the detection timing is not always constant with respect to the operation timing of the start lever. Since the random number lottery fluctuates at a high speed, it is possible to prevent the operation timing of the start lever from being synchronized with a specific cycle by slightly deviating the detection timing.

  The start lever operation detecting device according to the present invention can be configured so that the detection timing does not always become constant with respect to the operation timing of the start lever by changing only some parts. It is now possible to prevent illegal games in slot machines.

  As a preferred embodiment of the present invention, Example 1 is illustrated in FIGS. 1 to 5, Example 2 is illustrated in FIGS. 6 to 10, and Example 3 is illustrated in FIGS.

  In the start lever operation detecting device 1A of the first embodiment, the start lever 2 is attached to the lever holder 4 so as to be rotatable up and down with the fulcrum pin 3 as a fulcrum, and the tip of the lever shaft 5 integrated with the start lever 2 is It is a light shield 6A.

  A sliding body 7 is slidably fitted to the outer periphery of the lever shaft 5, and a lever return spring 9 is interposed between the sliding body 7 and the fixing ring 8. When the start lever 2 is rotated downward, the upper part of the sliding body 7 is pushed by the back surface of the lever holder 4 to compress the lever return spring 9 (see FIG. 3), and when the start lever 2 stops rotating. The start lever 2 is returned to the original horizontal position by the elastic force of the lever return spring 9 (see FIG. 1). In conjunction with the operation of the start lever 2, the light shield 6A swings up and down.

  An optical sensor 10 is attached to the back side of the lever holder 4. In the mounted state, the light emitting unit 11 and the light receiving unit 12 of the optical sensor 10 are positioned on both the left and right sides of the light blocking body 6A.

  The light shielding body 6A according to the first embodiment has a structure in which a movable portion 14 having a substantially triangular outer shape is fitted to the outer peripheral portion of a thin shaft-shaped shielding body main body 13 formed integrally with the lever shaft 5. Since the inner diameter of the hole 14a of the movable portion 14 into which the shield body 13 is fitted is considerably larger than the diameter of the shield body 13, the movable portion 14 moves up and down with respect to the shield body 13 by the impact of the operation of the start lever 2. Or the movable portion 14 rotates around the shield body 13.

  In the stationary state shown in FIG. 1, the shield 6 </ b> A is at the same height as the light emitting unit 11 and the light receiving unit 12. For this reason, even if the vertex of the movable part 14 is facing upward as shown in FIG. 1B, the vertex of the movable part 14 is facing downward as shown in FIG. However, the detection light emitted from the light emitting unit 11 is blocked by the light shielding body 6A and does not reach the light receiving unit 12. That is, the output of the optical sensor 10 is OFF.

  As shown in FIG. 3, when the start lever 2 is rotated downward, the shield 6 </ b> A moves upward, and the detection light from the light emitting unit 11 reaches the light receiving unit 12. That is, the output of the optical sensor 10 is turned on. However, the timing when the output is turned on is the state where the vertex of the movable part 14 is facing upward as shown in FIG. 3B and the state where the vertex of the movable part 14 is facing downward as shown in FIG. In contrast, the former, which has a shorter distance from the light shielding body 13 to the lower end of the movable portion 14, is turned on earlier.

  Since the state of the movable portion 14 changes due to an impact caused by the operation of the start lever 2, the detection timing is affected every time the start lever 2 is operated. Moreover, since the movable part 14 moves up and down with respect to the shield main body 13 by the impact by the operation of the start lever 2, even if the state of the movable part 14 is the same, the detection timing with respect to the operation timing is not necessarily constant.

  The start lever operation detection device 1B according to the second embodiment has almost the same configuration as that of the first embodiment, and only the light shield is different from the first embodiment. Parts having the same configuration are denoted by the same reference numerals, and description thereof is omitted. 6 corresponds to FIG. 1, FIG. 7 corresponds to FIG. 2, FIG. 8 corresponds to FIG. 3, FIG. 9 corresponds to FIG.

  The light shielding body 6B of the start lever operation detection device 1B has an elongated plate-like movable portion 16 that is rotatable about a left-right axis 17 at a bifurcated rear end portion of a shielding body 15 formed integrally with the lever shaft 5. Is attached. Since the inner diameter of the hole 16a of the movable portion 16 into which the shaft 17 is fitted is larger than the diameter of the shaft 17, the movable portion 16 moves up and down with respect to the shield body 15 by an impact caused by the operation of the start lever 2. The movable part 16 rotates around the shaft 17.

  In the stationary state shown in FIG. 6, the shield 6 </ b> B is at the same height as the light emitting unit 11 and the light receiving unit 12. For this reason, even if the movable part 16 is in the vertical orientation as shown in FIG. 6B, or the movable part 16 is in the horizontal orientation as shown in FIG. The detection light emitted from the unit 11 is blocked by the light blocking body 6B and does not reach the light receiving unit 12. That is, the output of the optical sensor 10 is OFF.

  As shown in FIG. 8, when the start lever 2 is turned downward, the shield 6 </ b> B moves up, and the detection light from the light emitting unit 11 reaches the light receiving unit 12. That is, the output of the optical sensor 10 is turned on. However, the timing when the output is turned on differs between the state in which the movable part 16 is in the vertical direction as shown in FIG. 8B and the state in which the movable part 16 is in the horizontal direction as shown in FIG. The latter with the short front and rear length of the light shielding body 6B is turned on earlier.

  Since the state of the movable portion 16 changes due to an impact caused by the operation of the start lever 2, the detection timing is affected every time the start lever 2 is operated. Moreover, since the movable part 16 moves up and down with respect to the shield body 15 by an impact caused by the operation of the start lever 2, even if the state of the movable part 16 is the same, the detection timing with respect to the operation timing is not necessarily constant.

  Also in the start lever operation detection device 1C of the third embodiment, the start lever 2 is provided so as to be rotatable up and down with the fulcrum pin 3 as a fulcrum. The start lever 2 is operated downward (see FIG. 12). When the finger is released after the operation, the start lever 2 returns to the original position by the elastic force of the lever return spring 20 (see FIG. 11). ).

  The light shield 6C of the start lever operation detection device 1C is integrally mounted with a wide plate-shaped light shield body 21 in the vertical direction with the start lever 2, and is movable in a hole 22 formed in the rear end portion of the light shield body 21. The part 23 is hooked and suspended. And the light emission part 11 and the light-receiving part 12 of the optical sensor 10 are arrange | positioned at the right-and-left both sides of the said light shielding body 6C. Since the lower edge of the hole 22 is uneven in a side view, the angle of the movable portion 23 changes depending on the position where the movable body 23 is hooked. The lower edge of the movable part 23 is also uneven in a side view, and the distances d1 and d2 from the lower end of the light shield 6C to the detection light passing position 24 differ depending on the angle of the movable part 23.

  In the stationary state shown in FIG. 11, the detection light emitted from the light emitting unit 11 is blocked by the light shield 6C and does not reach the light receiving unit 12, and the output of the optical sensor 10 is OFF. As shown in FIG. 12, when the start lever 2 is turned downward, the light shield 6C moves up so that the detection light from the light emitting unit 11 reaches the light receiving unit 12, and the output of the optical sensor 10 Is turned on. When the position of the central convex portion 23a at the lower edge of the movable portion 23 is shifted from the detection light passing position (FIG. 12) and when it matches (FIG. 13), the light shielding body 6C in the stationary state Since the distance from the lower end to the detection light passing position 24 is different (d1> d2), the detection timing with respect to the operation timing is different between the two.

  Since the state of the movable portion 23 changes due to an impact caused by the operation of the start lever 2, the detection timing is affected every time the start lever 2 is operated. Moreover, since the movable part 23 moves up and down with respect to the shield main body 21 by an impact caused by the operation of the start lever 2, even if the state of the movable part 23 is the same, the detection timing with respect to the operation timing is not necessarily constant.

  The present invention mainly relates to an apparatus for detecting an operation of a start lever for starting a game of a slot machine, but is not limited to a start lever of a slot machine, and other levers preferably having a detection timing with respect to an operation timing being random.
