A decorative panel 17, award medal outlet 18, a medal tray 19, an ashtray 20, and a lower speaker 21 are provided below the front frame 5.

  In addition, the inside of the housing 2 is divided into upper and lower portions by a mounting table 22, the variable display device 4 is mounted on the mounting table 22, and the position inside the housing 2 is higher than the variable display device 4. Is equipped with a game control unit 24 for comprehensively controlling the game progress of the slot machine 1. Further, a hopper unit 25 for discharging award medals is disposed below the mounting table 22 inside the housing 2, and a side of the hopper unit 25, specifically, the hopper unit 25 and the opening / closing central axis DL are arranged. Between the two, a standing box-like probability setting device (power supply device) 27 is arranged. The variable display device 4 includes three independently rotatable reels 29. The outer peripheral surface of the reel 29 is used as a display unit 8, and a plurality of pieces of identification information such as symbols and numerals are described on the display unit 8. Each reel 29 is rotated and stopped by a driving source (not shown) such as a motor to variably display the identification information and execute a variable display game. Then, the variable display of the identification information is stopped based on the operation of the stop button 12 by the player, and the result mode of the variable display game (specifically, the combination of the stopped identification information) is set in advance as a special result mode (for example, When the reels 29 are stopped with the same identification information facing the variable display opening 7), the game control unit 24 generates a special game state (so-called jackpot) and is determined in advance. The award medal as the special game value is set to be discharged from the award medal outlet 18 and given to the player.

Next, the probability setting device 27 will be described.
The probability setting device 27 has a probability (special result) that the result mode of the variable display game becomes a special result mode (for example, a stop mode in which three specific identification information items are stopped side by side, etc.). (Probability) can be set and changed in a plurality of stages (six stages in the present embodiment), and power can be supplied to each component such as the variable display device 4 and the hopper unit 25. As shown in FIG. 2, a setting operation unit 31 for changing the setting of the special result probability is arranged on the upper side of the front of the probability setting device 27 that can face the front frame 5. A power switch 32 for starting and stopping (ON / OFF) the slot machine 1 is provided on the side. Further, the setting operation section 31 includes a setting lock section (setting key insertion section) 33 for allowing or restricting the setting change of the special result probability, and a pressing operation (specifically, a protruding wall 42 of the covering member 40 described later ). A probability setting button 34 for stepwise changing the special result probability by an operation of pressing along the protruding direction), and a setting display section (7-segment LED) 35 for displaying the stage of the current special result probability. Each time the button 34 is pressed once, the special result probability is changed step by step. A portion of the front surface of the probability setting device 27 located outside the setting operation unit 31 and the power switch 32 is a contact outer peripheral portion 37, and the setting operation unit 31 and the power switch 32 are slightly more than the contact outer periphery 37. It protrudes to the front front frame 5 side (see FIG. 4A).

In order to change the special result probability of the slot machine 1 by operating such a setting operation unit 31, first, the power switch 32 is turned OFF to stop the slot machine 1, and a setting key (see FIG. (Not shown) is inserted, and in this state, the setting key is rotated to convert it into a setting permissible state (lock release state). If converted to the setting permissible state, the probability setting button 34 is pressed to change the special result probability. Then, with this change, a symbol representing the setting stage of the special result probability is displayed on the setting display unit 35 . When a symbol indicating the desired special result probability is displayed on the setting display unit 35 and the special result probability is set to a desired value, the setting key is rotated to return to the setting restricted state (locked state), Pull out from the setting lock 33. If the power switch 32 is turned on after setting the special result probability in this way, the slot machine 1 can be started in a state in which the special result probability after the setting change is reflected.

Then, as shown in FIG. 3, the slot machine 1 has a covering member 40 that can cover the setting operation unit 31 at a position facing the setting operation unit 31 in the closed state of the front frame 5 on the back surface of the front frame 5. Provided. The covering member 40 is a member made of an elastic body such as rubber or soft resin, and is set in a rectangular shape slightly smaller than the front surface of the probability setting device 27 (in other words, the outer periphery of the probability setting device 27) . Further, a rectangular frame-like protruding wall (contact protrusion) 42 made of an elastic body such as rubber or soft resin is probable at the peripheral edge of the back surface of the covering member 40 that can face the setting operation portion 31. A space surrounded by the protruding wall 42 is used as a housing space 43 (FIG. 4 (FIG. 4 (FIG. 4 (A))), and is integrally molded in a state protruding toward the setting device 27 and protruding along the front and back direction of the front frame 5. a) to (c)). Further, the protruding end 42a (tip positioned on the probability setting device 27 side) 42a of the protruding wall 42 is brought into contact with the contact outer peripheral portion 37 positioned outside the setting operation unit 31 and the power switch 32 on the front surface of the probability setting device 27. The projecting amount of the projecting wall 42 and the thickness dimension X1 in the front and back direction of the accommodating space 43 are set slightly longer than the projecting dimension X2 from the contact outer peripheral portion 37 of the setting operation unit 31 and the power switch 32. doing. Further, as shown in FIGS. 2, 4A and 4B, a contact detection sensor 45 constituted by a micro switch is provided in a portion of the contact outer peripheral portion 37 located above the setting display portion 35. The contact detection sensor 45 can detect that the covering member 40, specifically, the protruding end 42 a of the protruding wall 42 contacts the contact outer peripheral portion 37. Note that the contact detection sensor 45 is not limited to a micro switch, and may be any detection sensor as long as the contact of the protruding wall 42 can be detected. For example, a non-contact type optical sensor configured by combining a light emitting element and a light receiving element may be used.

  In the slot machine 1 having the probability setting device 27 and the covering member 40 having such a configuration, as shown in FIGS. 4A and 4C, when the front frame 5 is closed with respect to the housing 2, the slot machine 1 1, the peripheral edge of the covering member 40, specifically, the protruding end 42 a of the protruding wall 42 is brought into contact (close contact) with the contact outer peripheral portion 37, and the power switch 32, the setting lock portion 33, and the probability setting are set by the covering member 40. The button 34 and the setting display part 35 are covered with the front side accommodated in the accommodation space part 43, and the accommodation space part 43 is sealed by the probability setting device 27. Further, the covering member 40 is brought close to or in contact with the power switch 32 and the probability setting button 34 to such an extent that no ON / OFF operation or pressing operation is performed. Accordingly, the setting operation unit 31 and the power switch 32 can be covered with the covering member 40 only by closing the front frame 5, and an unauthorized member such as a piano wire is inserted between the front frame 5 and the probability setting device 27. Inconvenience, and inadvertent acts on the setting operation unit 31 and the power switch 32 due to unauthorized members can be easily prevented. If the front frame 5 is opened, the covering state of the setting operation unit 31 by the covering member 40 can be released without performing an operation separate from the opening operation of the front frame 5. From this, it is possible to quickly perform the probability setting operation without taking time and effort for the covering operation and the covering releasing operation of the setting operation unit 31 capable of preventing fraud.

  Further, in the state where the front frame 5 is closed, as shown in FIGS. 4B and 4D, the contact detection sensor 45 is pressed against the protruding wall 42, so that the covering member 40 and the contact outer peripheral portion 37 are pressed. A contact state with (probability setting device 27) is detected and a detection signal is generated. Further, the game control unit 24 can grasp not only that the covering member 40 is in the covering state but also that the front frame 5 is in the closed state based on the reception of the detection signal. When the front frame 5 is opened, the contact detection sensor 45 and the protruding wall 42 are separated (see FIG. 4E), and the contact detection sensor 45 is in contact with the covering member 40 and the probability setting device 27. The generation of the detection signal is stopped upon detecting the release. Further, the game control unit 24 can grasp not only that the covering state of the covering member 40 has been released but also that the front frame 5 has been opened based on the stop of reception of the detection signal. Therefore, the configuration for detecting the covering state of the setting operation unit 31 can function as a configuration for detecting the closed state of the front frame 5, and the structure of the slot machine 1 can be simplified. Further, it is possible to quickly detect a state in which the front frame 5 is opened and the covering state of the setting operation unit 31 is released, in other words, a state in which an illegal act on the setting operation unit 31 is easily performed.

By the way, in the said embodiment, although the contact outer peripheral part 37 of the probability setting apparatus 27 was formed in planar shape, this invention is not limited to this. For example, in the second embodiment shown in FIG. 5, the basic configuration is the same as in the first embodiment, but the structures of the contact outer peripheral portion 37 and the protruding wall 42 are different. Specifically, as shown in FIG. 5A, the probability setting device 27 forms a rectangular frame-like fitting groove 46 into which the protruding wall 42 can be fitted in the contact outer peripheral portion 37. A fitting detection sensor (contact detection sensor) 47 constituted by a micro switch is provided on the back side of the portion of the fitting groove 46 located above the setting display portion 35 , and the protruding wall 42 is fitted to the fitting groove 46. The fitting detection sensor 47 can detect that the protruding end 42a of the protruding wall 42 is in contact with the depth of the fitting groove 46. Further, as shown in FIG. 5D, the covering member 40 has a protruding dimension X3 of the protruding wall 42, a depth X4 of the fitting groove 46, and a contact outer peripheral portion 37 of the setting operation unit 31 and the power switch 32. Is set to be slightly longer than the sum of the protruding dimension X5 from the wall, and the wall thickness dimension W1 set along the direction orthogonal to the protruding direction of the protruding wall 42 is equal to or larger than the groove width dimension W2 of the fitting groove 46. Is set. Note that the fitting detection sensor 47 is not limited to being configured by a micro switch, and may be any detection sensor as long as the fitting of the protruding wall 42 can be detected. For example, a non-contact type optical sensor configured by combining a light emitting element and a light receiving element may be used.

  In the slot machine 1 having the projecting wall 42 and the fitting groove 46 having such a configuration, as shown in FIG. 5B, when the front frame 5 is closed with respect to the housing 2, the slot machine 1 is elastic. The protruding wall 42 composed of a body is fitted into the fitting groove 46 while being deformed, and the contact surface between the protruding wall 42 and the fitting groove 46 is bent in the front and back direction of the front frame 5 (front and rear direction of the slot machine 1). (See FIG. 5 (d)). The covering member 40 covers the power switch 32, the setting lock unit 33, the probability setting button 34, and the setting display unit 35 in a state where the front side is accommodated in the accommodating space 43, and the probability setting device covers the accommodating space 43. 27 to seal. Furthermore, the covering member 40 is brought close to or in contact with the power switch 32 and the probability setting button 34 to such an extent that no ON / OFF operation or pressing operation is performed. Therefore, it is sufficient that the unauthorized member is inserted between the probability setting device 27 and the covering member 40 only by closing the front frame 5 and that the unauthorized member reaches the setting operation unit 31 and the power switch 32. Therefore, it is possible to prevent inconvenience that an illegal act on the setting operation unit 31 and the power switch 32 is performed. Since the protruding wall 42 is formed of an elastic body and the wall thickness dimension W1 of the protruding wall 42 is set to be equal to or larger than the groove width dimension W2 of the fitting groove 46, a gap is formed in the fitting groove 46. It is possible to fit in a state that is not performed (so-called tight fit state), and it is possible to more reliably prevent the inconvenience of the unauthorized member reaching the setting operation unit 31 in the covered state. Moreover, even if the protruding wall 42 collides with the probability setting device 27, it is possible to suppress inconvenience that the probability setting device 27 is damaged. If the front frame 5 is opened, the covering state of the setting operation unit 31 by the covering member 40 can be released without performing an operation separate from the opening operation of the front frame 5.

  Further, as shown in FIG. 5C, when the front frame 5 is closed, the fitting detection sensor 47 is pressed by the projecting end 42a of the projecting wall 42 in a state of being fitted in the fitting groove 46. The fitting state between the protruding wall 42 and the fitting groove 46 is detected to generate a detection signal. Further, the game control unit 24 can grasp not only that the covering member 40 is in the covering state but also that the front frame 5 is in the closed state based on the reception of the detection signal. When the front frame 5 is opened, the fitting detection sensor 47 and the protruding wall 42 are separated, and the fitting detection sensor 47 detects that the fitting state between the protruding wall 42 and the fitting groove 46 has been released. Stop generating the detection signal. Further, the game control unit 24 not only detects that the fitting state of the protruding wall 42 and the fitting groove 46 is released and the covering state of the covering member 40 is released based on the stop of reception of the detection signal. It can also be understood that the frame 5 is in an open state. Therefore, the configuration for detecting the covering state of the setting operation unit 31 can function as a configuration for detecting the closed state of the front frame 5, and the structure of the slot machine 1 can be simplified. Further, the state in which the front frame 5 is opened and the covering state of the setting operation unit 31 and the power switch 32 is released, that is, the state in which the setting operation unit 31 and the power switch 32 are easily fraudulently detected is quickly detected. Can do. Furthermore, it becomes difficult for an unauthorized person to misoperate the fitting detection sensor 47 to cause a malfunction, and when the fitting detection sensor 47 malfunctions, the setting operation unit 31 and the power switch 32 are opened to perform an unauthorized act. Can be suppressed.

  By the way, in the said 2nd Embodiment, although the probability setting apparatus 27 was arrange | positioned in the housing | casing 2 in the state which cannot be rotated and the attitude | position of the fitting groove 46 was maintained, this invention is not limited to this.

  The probability setting device 27 can turn around the turning shaft portion 65, that is, around the turning center axis CL (see FIG. 8C), and the side portion of the probability setting device 27 is moved to the front posture engaging pin. When engaged with 68b, the fitting groove 46 is set to a posture in which the opening of the fitting groove 46 is opened toward the front of the slot machine 1 (front opening posture) (see FIG. 9B). On the other hand, the fitting groove 46 is opened toward the protruding end 42a side of the protruding wall 42 in the front frame 5 with the opening of the fitting groove 46 open, in other words, the opening of the fitting groove 46 is opened and closed. The posture is set to be inclined and opened toward the central axis DL side (tilted open posture) (see FIG. 9A). Therefore, even if the posture of the protruding wall 42 changes with the opening and closing of the front frame 5, the protruding wall 42 can be easily inserted (fitted) into the fitting groove 46. Thereby, the covering operation | movement of the setting operation part 31 can be performed smoothly. Moreover, the rotation mechanism 61 which can rotate the probability setting device 27 in a stable state can be realized. If the front frame 5 is sufficiently closed with the protruding wall 42 inserted into the fitting groove 46, the probability setting device 27 is pressed by the covering member 40 to convert from the inclined open posture to the front open posture.

By the way, in each of the above embodiments, the slot machine 1 has the power supply function in the probability setting device 27, but the present invention is not limited to this. In short, any configuration may be used as long as the probability setting device 27 can change the setting of the special result probability. For example, the power supply device may be provided separately from the probability setting device 27 and the power supply function may be removed from the probability setting device 27. The setting operation unit 31 includes the setting lock unit 33, the probability setting button 34, and the setting display unit 35. However, the present invention is not limited to this, and the setting of the special result probability can be changed. Any component may be provided.

  Furthermore, in each said embodiment, although the protrusion wall 42 protruded in the peripheral part of the coating | coated member 40, this invention is not limited to this, The peripheral part of the coating | coated member 40 is contact | abutted to the outer periphery 37 of the probability setting apparatus 27. Any configuration of the covering member 40 may be adopted as long as the contact can be made. For example, the peripheral portion of the covering member 40 may be gently bulged toward the probability setting device 27 and the bulged portion may be in contact with the contact outer peripheral portion 37 of the probability setting device 27.

  Furthermore, the present invention is not limited to being applied to a slot machine that uses medals as game media, but may be applied to a slot machine that uses pachinko balls as game media (so-called ball slot game machines).

  It should be understood that the above-described embodiment is illustrative in all respects and not restrictive. The present invention is not limited to the above description, but is defined by the scope of the claims, and includes all modifications within the scope and meaning equivalent to the scope of the claims.
