  The present invention relates to an inclination angle adjusting device for a gaming machine that adjusts an inclination angle of a game board surface in the gaming machine by tilting a gaming machine such as a pachinko gaming machine back and forth.

  In a gaming machine such as a pachinko gaming machine, the probability that a game ball enters the start port varies depending on the inclination angle of the game board surface. For this reason, in the trial firing test of the gaming machine, the trial firing of the game ball may be performed a plurality of times by changing the inclination angle of the game board surface. Conventionally, in order to change the inclination angle of the gaming board surface in a test firing test, first, the gaming machine is placed on a test stand and temporarily fixed with a predetermined gaming machine fixing handle. Next, hold the tilt sensor with one hand and tilt the gaming machine by loosening the gaming machine fixing handle while applying the tilt sensor to the gaming board surface. Here, as the tilt sensor, a commercially available sensor can be used. In addition to this, for example, a sensor having two protrusions having a length that can avoid a nail on the game board surface (for example, Patent Document 1). See). Then, when the measured value of the tilt sensor reaches the target angle, the gaming machine is fixed with the gaming machine fixing handle.

  By the way, in general, the tilt sensor has a structure in which an accurate value cannot be measured unless it is kept horizontal. As described above, conventionally, since the tilt sensor is supported with one hand when tilting the gaming machine, the tilt sensor is tilted due to camera shake or the like, and an accurate value may not be measured. In addition, since the game machine is tilted alone while observing the measured value of the tilt sensor, there is a problem that it takes time to adjust the tilt angle of the game board surface to the target angle.

A tilt angle is acquired based on the signal, a difference between the acquired tilt angle and a set value of the tilt angle sent from the input means is obtained, and the moving stage is moved so that the obtained difference becomes zero. And a control means for generating a drive control signal and outputting the drive control signal to the drive means.

  Further, in the tilt angle adjusting device for gaming machines of the present invention, a stepping motor is used as the driving means, and it is desirable that the stepping motor is equipped with an electromagnetic brake. As a result, the position of the moving stage of the gonio stage is maintained even when the power of the tilt angle adjusting device for gaming machines is turned off, so that the tilt angle of the game board surface remains at the target angle (set value). The game machine can be tilted.

  Furthermore, in the tilt angle adjusting device for a gaming machine according to the present invention, the detecting means detects the horizontal angle of the tilt sensor and outputs a signal corresponding to the detected horizontal angle, and the tilt sensor is in a substantially horizontal state. A horizontal display unit for displaying a certain effect, and the control means acquires a horizontal angle based on a signal corresponding to the horizontal angle output from the horizontal sensor of the detection means mounted on the game board surface, It is determined whether or not the acquired horizontal angle is within ± 1 °, and if the horizontal angle is within ± 1 °, a display control signal for displaying that the tilt sensor is in a substantially horizontal state is generated. It is desirable to output to the horizontal display part of the detection means. As a result, the user looks at the display of the horizontal display unit on the detection means and confirms whether the inclination sensor is in a substantially horizontal state while checking whether the inclination sensor is in a substantially horizontal state. Can be adjusted.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a schematic front view of a tilt angle adjusting device for gaming machines according to an embodiment of the present invention, and FIG. 2 is a schematic block diagram of the tilt angle adjusting device for gaming machines.

  The tilt angle adjusting device for a gaming machine according to the present embodiment is for adjusting the tilt angle of the game board surface in the gaming machine by tilting the gaming machine back and forth. Normally, the probability that a game ball enters the start port varies depending on the inclination angle of the game board surface. For this reason, in the trial firing test of the gaming machine, the trial firing of the game ball may be performed a plurality of times by changing the inclination angle of the game board surface. The gaming machine inclination angle adjusting device of the present embodiment can be used when a gaming machine manufacturer tests gaming machines. In general, since the game board surface is not necessarily flat, when measuring the inclination angle of the game board surface, it is necessary to specify the position on the game board surface where the inclination angle is measured.

  As shown in FIGS. 1 and 2, the gaming machine inclination angle adjusting device includes a frame body 10, a gonio stage 20, a stepping motor (STM) 30, two fixing levers 40 and 40, and a sensor unit 50. A mounting jig 60 (see FIGS. 6 and 8), an operation unit 70, and a control unit 80. A gonio stage 20, two fixing levers 40 and 40, and a control unit 80 are attached to the frame body 10. A game ball replenishing device 110 for replenishing game balls to the gaming machine is attached to the left side and the upper part of the central portion of the frame 10 so that a test fire test can be performed on the gaming machine.

  As shown in FIG. 1, the frame body 10 has a height H of about 2000 mm and a lateral width W of about 800 mm. Moreover, the height H2 of the lower part of the frame 10 is about 700 mm. The gonio stage 20 is provided in the lower part of the frame body 10, and the two fixing levers 40 and 40 are provided in the upper part of the frame body 10. Here, the distance H1 from the surface of the gonio stage 20 to the lower surface of the member to which the fixing levers 40, 40 are attached is about 830 mm.

  3A is a schematic plan view of the gonio stage 20, FIG. 3B is a schematic front view of the gonio stage 20, and FIG. 3C is a schematic right side view of the gonio stage 20. As shown in FIG. 3, the gonio stage 20 includes a moving table 21, a lead screw 22, a bush 23, and the like. The moving stage 21 is configured to be movable along an arc centered on an upper predetermined origin. As shown in FIG. 1, the gaming machine is placed on a moving stage 21. Here, although the height of the gaming machine varies depending on the manufacturer and the type of product, it is about 810 mm. The upper surface of the gaming machine placed on the moving stage 21 is pressed by the fixing levers 40, 40, whereby the gaming machine is temporarily fixed to the moving stage 21. FIG. 4 shows a schematic right side view of the tilt angle adjusting device for a gaming machine when the gaming machine is temporarily fixed to the moving stage 21. In FIG. 4, the game ball supply device 110 is omitted.

  As shown in FIGS. 3B and 3C, the lead screw 22 of the gonio stage 20 is attached to a bush 23, and the moving stage 21 is coupled to the bush 23. When the lead screw 22 rotates, the moving stage 21 moves back and forth together with the bush 23. Specifically, as shown in FIG. 4, the moving stage 21 has a radius R (centered on this origin) with the position P of the gaming machine that the fixed lever 40 contacts when the gaming machine is viewed from the side as the origin. Move along the arc of the height of the gaming machine. Here, the moving stage 21 moves forward or backward depending on the rotation direction of the lead screw 22. Thus, in this embodiment, the position P of the gaming machine with which the fixed lever 40 abuts is the rotation center of the moving stage 21.

  As shown in FIGS. 3B and 3C, a stepping motor 30 is attached to the lower side of the gonio stage 20. The stepping motor 30 is a driving means for moving the moving stage 21 back and forth along the arc. The rotating shaft of the stepping motor 30 and the rotating shaft of the lead screw 22 are connected by a timing belt 31. Thus, when the stepping motor 30 is driven, the rotational force of the stepping motor 30 is transmitted to the lead screw 22 via the timing belt 31, and the moving stage 21 moves together with the bush 23. Here, when the stepping motor 30 rotates in the clockwise direction, the moving stage 21 moves in the forward direction (+ direction), and when the stepping motor 30 rotates in the counterclockwise direction, the moving stage 21 moves in the backward direction (− direction). Move to. In the present embodiment, the stepping motor 30 is equipped with an electromagnetic brake. For this reason, the position of the moving stage 21 is maintained as it is even when the power of the tilt angle adjusting device for gaming machines is turned off.

  Further, as shown in FIG. 2, the gonio stage 20 includes three position detection sensors, that is, a home position detection sensor 25, a + direction movement limit point detection sensor 26, and a − direction movement limit point detection sensor 27. Is provided. As these three position detection sensors 25, 26, and 27, for example, limit switches are used. The gonio stage 20 has a mechanical origin of the moving stage 21. For example, a position where the moving stage 21 is in a substantially horizontal state is set as the machine origin. In the present embodiment, the machine origin is the home position of the moving stage 21. The home position detection sensor 25 detects that the moving stage 21 is located at the home position. The home position detection sensor 25 outputs a signal to the control unit 80 when detecting that the moving stage 21 is located at the home position.

  Further, the moving stage 21 can move back and forth only within a certain movable range due to its mechanism. The + direction movement limit point detection sensor 26 detects that the moving stage 21 is located at a limit point (+ direction movement limit point) that can move in the forward direction (+ direction). The output sensor 27 detects that the moving stage 21 is located at a limit point (−direction movement limit point) where it can move backward (− direction). For example, if the rotation angle of the movement stage 21 is 0 ° when the movement stage 21 is located at the home position, the + direction movement limit point is the rotation angle of the movement stage 21 when viewed from the rotation center P of the movement stage 21. The −direction movement limit point is a position where the moving stage 21 has moved in the − direction by a rotation angle of 2 ° when viewed from the rotation center P of the moving stage 21. When detecting that the moving stage 21 is positioned at the + direction movement limit point, the + direction movement limit point detection sensor 26 outputs a signal to the control unit 80, and the −direction movement limit point detection sensor 27 detects the movement stage 21. When it is detected that 21 is located at the negative direction movement limit point, a signal is output to the control unit 80. Since the rotational force of the stepping motor 30 is strong, if the stepping motor 30 is driven as it is even after the moving stage 21 reaches the + direction movement limit point or the − direction movement limit point, the lead screw 22 or the like is broken. There is a fear. Therefore, as will be described later, when the control unit 80 receives a signal from the + direction movement limit point detection sensor 26 or the −movement direction limit point detection sensor 27, the control unit 80 stops driving the stepping motor 30.

  As described above, the two fixing levers 40 and 40 are fixing means for temporarily fixing the gaming machine to the moving stage 21 by pressing the upper surface of the gaming machine placed on the moving stage 21. . In the present embodiment, “reach clamp (flange type)” manufactured by Imao Corporation is used as the fixing lever 40. FIG. 5 is a schematic front view of the fixing lever 40. As shown in FIG. 5, the fixed lever 40 includes a shaft 41, a main body portion 42 with a lever, and a circular pad 43 that is movably attached to the distal end portion of the shaft 41. The protruding amount of the shaft 41 can be adjusted. The lever-equipped main body 42 is provided with a clamp mechanism using a built-in spring. Specifically, the clamp stroke is 1.5 mm, and a load of 80 N can be applied to the gaming machine. After adjusting the protruding amount of the shaft 41 and bringing the tip (pad 43) of the shaft 41 into contact with the upper surface of the gaming machine, when the lever 42a of the main body portion 42 is turned to the clamp position, the upper surface of the gaming machine is moved to the shaft 41. The game machine is clamped by being pressed by the tip (pad 43). The pad 43 can be freely replaced.

  Thus, in the present embodiment, the fixed lever 40 is configured so that the protruding amount of the shaft 41 can be adjusted. In general, the height of the gaming machine differs somewhat depending on the gaming machine manufacturer. For this reason, by adjusting the protruding amount of the shaft 41, game machines having different heights can be firmly fixed by the two fixing levers 40 and 40. Further, since the fixing lever 40 is structured to be clamped by a built-in spring, the clamping force is always constant. For this reason, it is possible to avoid the gonio stage 20 from being damaged by applying a large force on the gonio stage 20 that is greater than the weight capable of being loaded.

  Next, the sensor part (detection means) 50 and the mounting jig 60 will be described. FIG. 6 is a schematic perspective view of the sensor unit 50 and the mounting jig 60. 7A is a schematic plan view of the sensor unit 50, FIG. 7B is a schematic front view of the sensor unit 50, FIG. 7C is a schematic left side view of the sensor unit 50, and FIG. d) is a schematic right side view of the sensor unit 50. As shown in FIGS. 2, 6, and 7, the sensor unit 50 includes an inclination sensor 51, a horizontal sensor 52, a substantially rectangular parallelepiped casing 53 that houses the inclination sensor 51 and the horizontal sensor 52, and the casing 53, a turntable 54 rotatably attached to one surface, three rod-like legs 55, 55, 55 attached to the turntable 54, and a turntable 54 (three legs 55, 55, 55) and a horizontal display portion 56 provided on the opposite surface of the housing 53. The sensor unit 50 is small and light. Specifically, as shown in FIG. 7, the lateral width D1 of the housing 53 is about 58 mm, the vertical width D2 is about 50 mm, and the height D3 is about 44 mm.

  The tilt sensor 51 detects the tilt angle of the gaming board surface in the gaming machine and outputs a signal (voltage value) corresponding to the detected tilt angle to the control unit 80. As the inclination sensor 51, a sealed type is used. In the present embodiment, the inclination angle of the game board surface refers to an angle at which the normal line of the game board surface at a predetermined position on the game board surface is inclined with respect to the horizontal plane, and when the game board surface faces upward. Let it be +. The horizontal sensor 52 detects the horizontal angle of the tilt sensor 51 and outputs a signal (voltage value) corresponding to the detected horizontal angle to the control unit 80. A signal transmission / reception cable 57 is drawn from the lower surface of the housing 53, and this cable 57 is connected to the control unit 80.

  As shown in FIGS. 7A and 7B, a turntable 54 is attached to the left side surface of the casing 53, and the three legs 55, 55, 55 are placed on the turntable 54 at a predetermined interval, for example, It is attached at regular intervals. For this reason, by rotating the turntable 54, the three legs 55, 55, 55 can be rotated together. Moreover, as each leg part 55, the thing longer than the length of the nail on a game board surface is used. A typical nail has a length of about 20 mm, whereas each leg 55 has a length L of about 30 mm. Furthermore, the tip of each leg 55 is formed in a convex shape.

  The angle detection by the sensor unit 50 is performed in a state where the three leg portions 55, 55, 55 are in contact with the game board surface. The mounting jig (attachment) is used to attach the sensor unit 50 to a desired position on the game board surface in the gaming machine with the three legs 55, 55, 55 in contact with the game board surface in this way. Means) 60. FIG. 8 is a view showing a state when the sensor unit 50 is attached to the game board surface using the attachment jig 60. As shown in FIGS. 6 and 8, the mounting jig 60 includes a rubber belt 61 and mounting means 62 for mounting on a nail on the game board surface provided at each end of the belt 61. , 62. For example, as the mounting means 62, a structure that can be mounted on a nail with a nail on the surface of the game board sandwiched, such as a clothespin, can be used. As shown in FIG. 8, each mounting means 62 is mounted on a nail located on both sides of the sensor unit 50, and the belt 61 is provided on the opposite side to the surface of the casing 53 on which three legs 55, 55, 55 are provided. By pressing the surface toward the game board surface, the sensor unit 50 is mounted on the game board surface in a state where the three legs 55, 55, 55 are in contact with the game board surface. Thus, in this embodiment, the sensor unit 50 can be easily mounted on the game board surface by using the mounting jig 60 having the belt 61 and the two mounting means 62 and 62. In addition, since the sensor unit 50 is supported on the game board surface by the three legs 55, 55, 55, the nail on the game board surface does not get in the way, and the sensor unit 50 can be placed at any position on the game board surface. Can be attached stably. In particular, since the three leg portions 55, 55, 55 are configured to be integrally rotatable, when the sensor portion 50 is to be attached to a desired position on the game board surface, it happens to be at a location corresponding to the leg portion 55. Even if there is a nail, if the three legs 55, 55, 55 are rotated as a whole and the positions of the three legs 55, 55, 55 with respect to the housing 53 of the sensor 50 are changed, the sensor 50 is It can be attached at a desired position.

  The horizontal display unit 56 of the sensor unit 50 is provided on the surface opposite to the surface of the housing 53 on which the turntable 54 is provided. The horizontal display unit 56 displays whether or not the horizontal angle of the tilt sensor 51 is within ± 1 °, that is, whether or not the tilt sensor 51 is in a substantially horizontal state, and includes three LEDs (Light Emitting Diodes). 56a, 56b, 56c. The center LED 56a emits green light, and the left and right LEDs 56b and 56c emit orange light. The center LED 56a lights up when the horizontal angle of the tilt sensor 51 is within ± 1 °. For this reason, the lighting of the central LED 56a means that the tilt sensor 51 is in a substantially horizontal state. On the other hand, the left LED 56b is turned on when the horizontal angle of the inclination sensor 51 is larger than 1 ° and the left end of the inclination sensor 51 is inclined downward, and the right LED 56c is turned on horizontally. Lights when the angle is larger than 1 ° and the right end of the tilt sensor 51 is tilted downward. Lighting control of each LED 56a, 56b, 56c is performed by the control unit 80. Therefore, the user looks at the lighting display of the horizontal display unit 56 and confirms whether the tilt sensor 51 is in a substantially horizontal state while checking whether the tilt sensor 51 is currently in a substantially horizontal state. The tilt can be adjusted. In this way, the inclination of the sensor unit 50 is adjusted so that the inclination sensor 51 is in a substantially horizontal state. The inclination sensor 51 detects an accurate inclination angle unless the horizontal angle is within ± 1 °. It is because it is not possible. For this reason, it is necessary to adjust the inclination of the sensor unit 50 before starting the process of adjusting the inclination angle of the game board surface.

  The tilt angle adjusting device for a gaming machine according to the present embodiment includes an automatic adjustment function for automatically adjusting the tilt angle of the gaming board surface in the gaming machine so as to be a set value input from the operation unit 70, and the user operates the operation unit. And a manual adjustment function for manually adjusting the inclination angle of the game board surface by operating 70. The operation unit (input unit) 70 is used to input an instruction necessary for causing the control unit 80 to execute processing according to the automatic adjustment function or the manual adjustment function. FIG. 9 is a schematic front view of the operation unit 70. Specifically, as illustrated in FIG. 9, the operation unit 70 includes an inclination angle input unit 71, a function selection unit 72, and a detected inclination angle display unit 73. The tilt angle input unit 71 is used to input a set value of the tilt angle of the game board surface when automatically adjusting the tilt angle of the game board surface, and includes a numeric keypad 711 and a set value display unit 712. When the user inputs a set value of the tilt angle of the game board surface using the numeric keypad 711, the input set value is displayed on the set value display unit 712. In the present embodiment, the set value of the inclination angle of the game board surface can be input in units of 0.01 ° within a range of + 3 ° to −1 ° (see FIG. 4). Further, as the set value display unit 712, a 7-segment display device using LEDs is used.

  Further, the function selection unit 72 instructs to start the process of automatically adjusting the tilt angle of the game board surface, or instructs to perform the process of manually adjusting the tilt angle of the game board surface. . The function selection unit 72 includes an automatic key 721, a manual key 722, a Δ key 723, a ▽ key 724, a registration key 725, a call key 726, a cancel key 727, and a home key 728.

  The automatic key 721 is used to instruct to start processing for automatically adjusting the inclination angle of the game board surface. When the automatic key 721 is pressed while the setting value is displayed on the setting value display unit 712, a signal indicating that processing for automatically adjusting the inclination angle of the game board surface and data regarding the setting value are operated. Sent from the unit 70 to the control unit 80. Then, when receiving these signals, the control unit 80 starts a process of automatically adjusting the inclination angle of the game board surface so that the inclination angle of the game board surface becomes the set value.

  The registration key 725 is used to instruct to register the setting value of the tilt angle input using the numeric key 711. When the registration key 725 is pressed while the setting value is displayed on the setting value display unit 712, a signal indicating that the registration process is performed and data on the setting value of the tilt angle are transmitted from the operation unit 70 to the control unit 80. Sent. Upon receiving these signals, the control unit 80 stores and registers the set value of the tilt angle in a predetermined storage unit. The call key 726 is for instructing to call the set value of the tilt angle already registered in the control unit 80. When the call key 726 is pressed, a signal for calling the registered set value is sent from the operation unit 70 to the control unit 80. When the control unit 80 receives the signal, the control unit 80 outputs data about the set value registered in the predetermined storage unit to the operation unit 70, whereby the set value is displayed on the set value display unit 712. The The cancel key 727 is used to instruct to cancel the registration of the currently registered setting value. When the cancel key 727 is pressed, a signal to cancel the registration is sent from the operation unit 70 to the control unit 80, and the control unit 80 deletes the data regarding the set value currently registered in the storage means. The home key 728 is for instructing to move the moving stage 21 to the home position. When the home key 728 is pressed and a signal to that effect is sent from the operation unit 70 to the control unit 80, the control unit 80 performs a process of moving the moving stage 21 to the home position.

  The manual key 722 is used to instruct to perform processing for manually adjusting the inclination angle of the game board surface. When the manual key 722 is pressed, a signal indicating that processing for manually adjusting the tilt angle of the game board surface is performed is sent from the operation unit 70 to the control unit 80. When receiving this signal, the control unit 80 waits for an instruction to execute a process for manually adjusting the inclination angle of the game board surface. The △ key 723 is used to instruct execution of a process for moving the moving stage 21 by a predetermined distance in the + direction when the inclination angle of the game board surface is manually adjusted. The ▽ key 724 is used to play the game board surface. This is for instructing execution of a process of moving the moving stage 21 by a predetermined distance in the-direction when manually adjusting the tilt angle. When the Δ key 723 or the ▽ key 724 is pressed, a signal indicating that the key has been pressed is sent to the control unit 80. When the control unit 80 receives the signal, the stepping motor 30 moves the moving stage 21 by a predetermined distance in a predetermined direction if the control unit 80 is currently waiting for an instruction to execute the manual adjustment process of the tilt angle. Control the drive.

  As described above, since the tilt sensor 51 cannot detect an accurate tilt angle unless the horizontal angle is within ± 1 °, the user can detect the center of the horizontal display unit 55 of the sensor unit 50. It is necessary to operate the automatic key 721 or the manual key 722 after confirming that the LED 56a is turned on.

  The detected inclination angle display unit 73 displays the inclination angle of the game board surface detected by the inclination sensor 51. As the detected inclination angle display unit 73, a 7-segment display device using LEDs is used. As long as a signal corresponding to the inclination angle is sent from the inclination sensor 51, the control unit 80 always obtains the inclination angle of the game board surface based on the signal and displays the obtained inclination angle. Is output to the detected inclination angle display unit 73. Therefore, the detected tilt angle display unit 73 displays the tilt angle of the game board surface in real time.

  Next, the control unit (control means) 80 will be described. The control unit 80 is placed on the moving stage 21 by controlling the display of the horizontal display unit 56 of the sensor unit 50, the display of the detected tilt angle display unit 73 of the operation unit 70, or the driving of the stepping motor 30. The inclination angle of the game board surface in the gaming machine that has been made is adjusted. As shown in FIG. 2, the control unit 80 includes a first A / D converter 81a and a second A / D converter 81b, a first processing unit 82, a horizontal display driver 83, and a second processing unit. Part 84, a detected inclination angle display part driver 85, interfaces 86a and 86b, and a stepping motor driver 87. Here, each of the first processing unit 82 and the second processing unit 84 is configured by a microcomputer.

  A signal (voltage value) corresponding to the tilt angle from the tilt sensor 51 is input to the first A / D converter 81a. The first A / D converter 81a converts a signal corresponding to the input tilt angle into digital data. The digital data converted by the first A / D converter 81a is output to the first processing unit 82. A signal (voltage value) corresponding to the horizontal angle from the horizontal sensor 52 is input to the second A / D converter 81b. The second A / D converter 81b converts a signal corresponding to the input horizontal angle into digital data, and the digital data converted by the second A / D converter 81b is the first processing unit 82. Is output.

  The first processing unit 82 processes a signal sent from the sensor unit 50 and controls the display of the horizontal display unit 56 of the sensor unit 50. As shown in FIG. 2, the first processing unit 82 includes an inclination angle data generation unit 821, a comparison calculation unit 822, a display control signal generation unit 823, and a storage unit (not shown). The tilt angle data generating unit 821 generates data about the measured value of the tilt angle based on the digital data sent from the first A / D converter 81a. In this embodiment, as described above, a sealed type sensor is used as the tilt sensor 51. However, due to the characteristics of this sealed tilt sensor, the signal output from the tilt sensor 51 includes an error. . For example, the tilt sensor 51 does not show a linear response to changes in tilt angle. For this reason, since the measured value of the tilt angle obtained from the signal corresponding to the tilt angle output from the tilt sensor 51 is not an accurate value, it is necessary to correct (calibrate) the measured value of the tilt angle. In the present embodiment, while the gaming machine is tilted forward and backward, a measured value of the tilt angle is obtained from a signal corresponding to the tilt angle output from the tilt sensor 51, and at that time, the sensor unit 50 uses an optical device. The measured value (calibration value) of the tilt angle at the position on the attached game board surface is obtained. Then, a table showing the relationship between the measured value of the tilt angle obtained from the signal output from the tilt sensor 51 and the calibration value of the tilt angle obtained using the optical device is created and stored in the storage means. ing. The tilt angle data generation unit 821 obtains a calibration value of the tilt angle from the measured value of the tilt angle based on this table. Data (tilt angle data) regarding the calibration value of the tilt angle obtained in this way is output to the second processing unit 84.

  The comparison calculation means 822 acquires the horizontal angle of the tilt sensor 51 based on the digital data sent from the second A / D converter 81b, and determines whether or not the acquired horizontal angle is within ± 1 °. To do. The display control signal generation unit 823 generates a signal (lighting display control signal) for controlling the lighting display of the horizontal display unit 56 based on the data indicating the determination result from the comparison calculation unit 822. Specifically, when the data indicating the determination result that the horizontal angle is within ± 1 ° is sent from the comparison calculation unit 822, the display control signal generation unit 823 turns on the LED 56a at the center of the horizontal display unit 56. A lighting display control signal is generated for output to the horizontal display unit 56 of the sensor unit 50 via the horizontal display unit driver 83. As a result, the central LED 56a of the horizontal display unit 56 is lit in green. Also, data indicating the determination result that the horizontal angle is larger than + 1 °, that is, the horizontal angle is larger than 1 ° and the left side of the tilt sensor 51 is tilted downward is sent from the comparison calculation means 822. Then, the display control signal generation unit 823 generates a lighting display control signal for lighting the left LED 56 b of the horizontal display unit 56 and outputs it to the horizontal display unit 56 via the horizontal display driver 83. . Thereby, the left LED 56b of the horizontal display unit 56 is lit in orange. Further, data indicating the determination result that the horizontal angle is smaller than −1 °, that is, the horizontal angle is larger than 1 ° and the right side of the tilt sensor 51 is tilted downward is obtained from the comparison calculation means 822. When sent, the display control signal generation means 823 generates a lighting display control signal for lighting the right LED 56 c of the horizontal display unit 56 and outputs it to the horizontal display unit 56 via the horizontal display driver 83. To do. As a result, the right LED 56c of the horizontal display unit 56 is lit in orange.

  As described above, in the first processing unit 82, the tilt angle data generation process by the tilt angle data generation unit 821 and the display control process of the horizontal display unit 56 by the comparison calculation unit 822 and the display control signal generation unit 823 are asynchronous. To be executed. If the signal from the sensor unit 50 is input via the A / D converters 81a and 81b regardless of whether the automatic key 721 or the manual key 722 is pressed on the operation unit 70, the first processing unit 82 is The above processes are executed. Accordingly, the horizontal display unit 56 of the sensor unit 50 displays in real time whether the tilt sensor 51 is in a substantially horizontal state.

  The second processing unit 84 controls the display of the detected tilt angle display unit 73 of the operation unit 70 or controls the driving of the stepping motor 30 to tilt the game board surface in the gaming machine placed on the moving stage 21. The angle is adjusted. In addition, when a predetermined signal is sent from the operation unit 70, the second processing unit 84 performs processing according to the signal. Specifically, when a signal indicating that the registration process for the set value of the tilt angle and the data about the set value of the tilt angle are sent from the operation unit 70 via the interface 86a, the second processing unit 84 A process for registering the setting value of the tilt angle is performed. In addition, when a signal for calling the registered inclination angle setting value is transmitted from the operation unit 70 via the interface 86a, the second processing unit 84 outputs data on the setting value to the operation unit 70. . Further, when a signal for canceling registration of the currently registered setting value is transmitted from the operation unit 70 via the interface 86a, the second processing unit 84 deletes data regarding the setting value.

  As shown in FIG. 2, the second processing unit 84 stores display control signal generation unit 841, comparison calculation unit 842, drive control signal generation unit 843, various data sent from the operation unit 70, and the like. Storage means (not shown). The display control signal generation means 841 is for causing the detected inclination angle display section 73 to display the content indicated by the inclination angle data based on the inclination angle data sent from the inclination angle data generation means 821 of the first processing section 82. A display control signal is generated. The display control signal generated by the display control signal generation unit 841 is sent to the detected tilt angle display unit 73 of the operation unit 70 via the detected tilt angle display unit driver 85, and is thereby detected by the tilt sensor 51. The inclination angle of the game board surface is displayed on the detected inclination angle display unit 73. The processing by the display control signal generation unit 841 is executed when tilt angle data is input from the first processing unit 70 regardless of whether the automatic key 721 or the manual key 722 is pressed on the operation unit 70.

  The comparison calculation means 842 receives the signal indicating that the automatic key 721 is pressed in the operation unit 70 and the process of automatically adjusting the tilt angle of the gaming machine and the data about the set value of the tilt angle from the operation unit 70 to the interface 86a. The predetermined difference process is started when the message is sent via. Specifically, in this difference process, the setting value of the tilt angle sent from the operation unit 70 and the calibration of the tilt angle that is the content of the tilt angle data sent from the tilt angle data generating means 821 of the first processing unit 82 are corrected. A difference from the value is obtained, and data (difference data) about the obtained difference is output to the drive control signal generation unit 843. Note that the data about the set value of the tilt angle sent from the operation unit 70 is stored in the storage means of the second processing unit 84.

  The drive control signal generation unit 843 generates a drive control signal for driving the stepping motor 30. Specifically, when processing for automatically adjusting the tilt angle of the gaming machine is performed, when difference data is sent from the comparison calculation means 842, the drive control signal generation unit 843 causes the difference to become zero. A drive control signal for moving the moving stage 21 is generated. Here, as the drive control signal, a signal (pulse signal) for controlling the rotation direction and the rotation speed of the stepping motor 30 is generated. The rotation direction of the stepping motor 30 is determined based on the sign of the difference, and the rotation speed of the stepping motor 30 is determined such that the larger the difference, the faster the rotation speed. However, in this embodiment, in order to perform control easily, when the magnitude of the difference is equal to or greater than a predetermined value, the stepping motor 30 is rotated at a high rotation speed, and the magnitude of the difference is the predetermined value. The stepping motor 30 is rotated at a low rotation speed when the rotation speed is smaller than that. Further, when processing for manually adjusting the tilt angle of the gaming machine is performed, that is, a signal indicating that processing for manually adjusting the tilt angle of the game board surface is performed when the manual key 722 is pressed in the operation unit 70 is operated. When sent from the unit 70, when a signal indicating that the Δ key 723 or the ▽ key 724 is pressed is sent from the operation unit 70, the drive control signal generation unit 843 generates a predetermined drive control signal. Specifically, when a signal indicating that the Δ key 723 is pressed is sent, the drive control signal generator 843 rotates the stepping motor 30 in the clockwise direction at a constant rotational speed for a predetermined time. When a drive control signal is generated and a signal indicating that the ▽ key 724 has been pressed is sent, a drive control signal that rotates the stepping motor 30 in a counterclockwise direction at a constant rotational speed for a predetermined time is generated. Generate. The drive control signal generation unit 843 receives a signal from the + direction movement limit point detection sensor 26 or a signal from the −direction movement limit point detection sensor 27 via the interface 86b during the process of generating the above-described drive control signal. Is received, the generation of the drive control signal is stopped.

  The drive control signal generated by the drive control signal generator 843 is output to the stepping motor 30 via the stepping motor driver 87, and the stepping motor 30 is driven. The driving force of the stepping motor 30 is transmitted to the lead screw 22 via the timing belt 31, and the moving stage 21 moves together with the bush 23 attached to the lead screw 22. In particular, during the execution of the process of automatically adjusting the tilt angle, when the moving stage 21 moves in this manner, the tilt angle of the game board surface changes, so that the same is again performed based on the calibration value of the tilt angle after the change. An inclination angle adjustment process is performed. Then, when the calibration value of the tilt angle matches the set value of the tilt angle and the difference data indicating that the difference is zero is sent from the comparison calculation means 842, the drive control signal generation unit 843 generates the drive control signal. Accordingly, the movement of the moving stage 21 is stopped.

  When the drive control signal generation unit 843 receives a signal indicating that the home key 728 has been pressed from the operation unit 70 via the interface 86a, the drive control signal generation unit 843 performs a process of moving the moving stage 21 to the home position. Specifically, the drive control signal generation unit 843 first generates a drive control signal for moving the moving stage 21 in the − direction and continues to send it to the stepping motor 30 via the stepping motor driver 87. When receiving a signal from the −direction movement limit point detection sensor 27 via the interface 86b, the drive control data generation unit 843 generates a drive control signal for moving the moving stage 21 in the + direction, and the stepping motor. Continue to be sent to the stepping motor 30 via the driver 87. Thereafter, when a signal from the home position sensor 25 is received via the interface 86b, the drive control signal generation unit 843 stops generating the drive control signal. Thus, the moving stage 21 stops at the home position. The operation of pressing the home key 728 is performed before placing the gaming machine on the gonio stage 20.

Next, how to use the tilt angle adjusting device for gaming machines of this embodiment will be described.
First, the user presses the home key 728 of the operation unit 70 to move the moving stage 21 to the home position. Thereafter, the user installs the gaming machine on the gonio stage 20. Specifically, the gaming machine is placed on the moving stage 21. And after adjusting the protrusion amount of the shaft 41 in each fixed lever 40, and making the pad 43 contact | abut on the upper surface of a game machine, the lever 42a of the main-body part 42 is turned to a clamp position. Thereby, as shown in FIGS. 1 and 4, the gaming machine is firmly fixed on the moving stage 21 by the two fixing levers 40 and 40.

  Next, the user attaches the sensor unit 50 on the gaming board surface of the gaming machine. Specifically, first, the sensor unit 50 is arranged at a desired position on the game board surface (for example, in the vicinity of the start port) with the three legs 55, 55, 55 being in contact with the game board surface. Then, after one mounting means 62 of the mounting jig 60 is mounted on a nail located near the sensor unit 50, the belt 61 is turned to the opposite side beyond the housing 53 of the sensor unit 50, and the other mounting means is mounted. Attach 62 to the nail. As a result, the sensor unit 50 is pressed against the game board surface by the belt 61 and is firmly fixed. At this time, the user looks at the horizontal display unit 56 of the sensor unit 50 and confirms whether the central LED 56a is lit. If the center LED 56a is not lit and the left LED 56b or the right LED 56c is lit, the user adjusts the inclination of the sensor unit 50 so that the center LED 56a is lit. Thus, when the central LED 56a is lit, the sensor unit 50 is mounted on the game board surface so that the tilt sensor 51 is in a substantially horizontal state.

  Next, the user operates the operation unit 70 to adjust the inclination angle of the game board surface. When automatically adjusting the inclination angle of the game board surface, first, the user inputs a setting value of the inclination angle of the game board surface using the numeric keypad 711 in the inclination angle input unit 71 of the operation unit 70. Thereafter, the automatic key 721 of the function selection unit 72 is pressed. As a result, a signal to start processing for automatically adjusting the tilt angle of the game board surface and data about the input tilt angle setting value are sent from the operation unit 70 to the second processing unit 84 of the control unit 80. Upon receiving these signals, the second processing unit 84 starts a process of automatically adjusting the tilt angle of the game board surface and controls the movement of the moving stage 21. Then, when the inclination angle of the game board surface becomes equal to the set value, the movement of the moving stage 21 is stopped. When manually adjusting the inclination angle of the game board surface, first, the user presses the manual key 722 in the function selection unit 72 of the operation unit 70. As a result, a signal indicating that the process of manually adjusting the inclination angle of the game board surface is sent from the operation unit 70 to the control unit 80. Next, the user looks at the inclination angle currently displayed on the detected inclination angle display unit 73, and if the current inclination angle is smaller than the target inclination angle, the user presses the Δ key 723, while the current inclination angle is displayed. If the tilt angle is larger than the target tilt angle, the Δ key 724 is pressed. As a result, a signal indicating that the key has been pressed is sent from the operation unit 70 to the control unit 80. When the second processing unit 84 receives the signal, the moving stage 21 is moved in a direction corresponding to the key by a predetermined distance. Only move it. After that, while viewing the tilt angle displayed on the detected tilt angle display unit 73, the Δ key 723 or the ▽ key 724 is pressed several times, and when the target tilt angle is displayed on the detected tilt angle display unit 73, The user stops the operation of the Δ key 723 or the ▽ key 724. Thus, in the gaming machine inclination angle adjusting device of the present embodiment, the inclination angle of the gaming board surface becomes a desired angle with a simple operation regardless of which of the automatic adjustment function and the manual adjustment function is used. So that the gaming machine can be tilted.

  Next, the procedure of the process for automatically adjusting the tilt angle of the game board performed by the second processing unit 84 of the control unit 80 will be described. FIG. 10 is a flowchart for explaining the procedure of the automatic adjustment processing of the inclination angle of the game board performed by the second processing unit 84.

  When the second processing unit 84 acquires the signal for starting the process of automatically adjusting the tilt angle of the game board surface and the data about the set value of the tilt angle through the interface 86a, the game board surface according to the flow of FIG. The process of automatically adjusting the tilt angle of the camera is started. At this time, the acquired data regarding the set value of the tilt angle is temporarily stored in the storage means of the second processing unit 84 (S11).

  When the automatic adjustment processing of the tilt angle is started, the comparison calculation unit 842 acquires the tilt angle data sent from the tilt angle data generation unit 821 of the first processing unit 82 (S12). Then, the difference between the set value of the tilt angle sent from the operation unit 70 and the calibration value of the tilt angle which is the content of the acquired tilt angle data is obtained (S13). Here, this difference is obtained by subtracting the “inclination angle calibration value” from the “inclination angle setting value”. The comparison calculation unit 842 outputs data (difference data) about the obtained difference to the drive control signal generation unit 843.

  Next, when receiving the difference data from the comparison calculation means 642, the drive control signal generation means 843 first determines whether or not the difference is zero (S14). If the difference is not zero, it is determined whether the difference is a positive value (S15). Here, the fact that the difference is a positive value means that the inclination angle of the game board is currently smaller than the set value.

  If it is determined in step S15 that the difference is a positive value, the drive control signal generator 843 determines whether or not a signal is sent from the + direction movement limit point detection sensor 26 via the interface 86b. (S16). If the signal from the + direction movement limit point detection sensor 26 is sent, the moving stage 21 is currently positioned at the + direction movement limit point and cannot be moved further in the + direction. The automatic adjustment processing of the tilt angle is terminated without generating 30 drive control signals. On the other hand, if it is determined that the signal from the + direction movement limit point detection sensor 26 has not been sent, the drive control signal generation means 843 has a positive value, so that the rotation direction of the stepping motor 30 is clockwise. It is determined to generate a drive control signal in the direction (CW) (S17). Here, when the stepping motor 30 rotates in the clockwise direction, the moving stage 21 moves in the + direction. Thereafter, the drive control signal generation unit 843 determines whether or not the difference is within a range larger than 0 ° and smaller than 0.2 ° (S18). When it is determined that the difference is included in this range, the drive control signal generation unit 843 determines to rotate the stepping motor 30 in the clockwise direction at a low speed (S19), and the difference is within the above range. If it is determined that it is not included, the drive control signal generator 483 determines to rotate the stepping motor 30 in the clockwise direction at high speed (S20).

  If it is determined in step S15 that the difference is a negative value, the drive control signal generation unit 843 determines whether a signal is transmitted from the negative direction movement limit point detection sensor 27 via the interface 86b. Is determined (S21). If the signal from the -direction movement limit point detection sensor 27 is sent, the moving stage 21 is currently positioned at the -direction movement limit point and cannot be moved further in the-direction. The automatic adjustment processing of the tilt angle is terminated without generating 30 drive control signals. On the other hand, if it is determined that the signal from the negative direction movement limit point detection sensor 27 has not been sent, the drive control signal generation means 843 has a negative value, so that the rotation direction of the stepping motor 30 is counterclockwise. It is determined to generate a drive control signal that results in the turning direction (CCW) (S22). Here, when the stepping motor 30 rotates counterclockwise, the moving stage 21 moves in the-direction. Thereafter, the drive control signal generation unit 843 determines whether or not the difference is within a range larger than −0.2 ° and smaller than 0 ° (S23). When it is determined that the difference is included in this range, the drive control signal generation unit 843 determines to rotate the stepping motor 30 in the counterclockwise direction at a low speed (S24). If it is determined that it is not included in the range, the drive control signal generator 483 determines to rotate the stepping motor 30 in the counterclockwise direction at high speed (S25).

  When the rotation speed and rotation direction of the stepping motor 30 are thus determined by the processing of step S19, S20, S24 or S25, the drive control signal generation means 843 generates a drive control signal having the determined contents, and for the stepping motor. It outputs to the stepping motor 30 via the driver 87 (S26). As a result, the stepping motor 30 is driven and the moving stage 21 is moved. When the moving stage 21 moves, the inclination angle of the game board surface changes, so after the process in step S26 is completed, the process proceeds to step S12 again, and the second processing unit 84 creates new difference data (S13). Then, a process of generating a drive control signal based on the created difference data (S14 to S26) is performed. When it is determined in step S14 that the difference is zero, the inclination angle of the game board surface matches the set value. At this time, the second processing unit 84 automatically adjusts the inclination angle. And the movement of the moving stage 21 is stopped.

  In the gaming machine tilt angle adjusting device of the present embodiment, the control unit acquires the tilt angle based on a signal corresponding to the tilt angle output from the tilt sensor of the sensor unit mounted on the game board surface, and acquires the tilt angle. Stepping is performed by generating a drive control signal for moving the moving stage of the gonio stage so that the obtained difference between the tilt angle and the set value of the tilt angle sent from the operation unit becomes zero. Output to the motor. Thereby, the inclination angle of the game board surface in the gaming machine can be automatically adjusted so that the inclination angle at the position on the game board surface to which the sensor unit is attached becomes the set value sent from the operation unit. For this reason, if the inclination angle adjusting device for gaming machines of the present embodiment is used, it is possible to perform a test firing test of gaming machines by changing the inclination angle of the gaming board surface in various ways.

  Further, in the gaming machine tilt angle adjusting device of the present embodiment, since the stepping motor is equipped with an electromagnetic brake, even if the gaming machine tilt angle adjusting device is turned off, the gonio stage moves. Since the position of the stage is maintained, the gaming machine can be tilted while keeping the tilt angle of the game board surface at a target angle (set value).

  Furthermore, in the gaming machine tilt angle adjusting device of the present embodiment, the sensor unit includes a horizontal sensor that detects the horizontal angle of the tilt sensor, and a horizontal display unit that displays that the tilt sensor is in a substantially horizontal state. The control unit acquires a horizontal angle based on a signal corresponding to the horizontal angle output from the horizontal sensor of the sensor unit mounted on the game board surface, and whether the acquired horizontal angle is within ± 1 °. If the horizontal angle is within ± 1 °, a display control signal for displaying that the tilt sensor is in a substantially horizontal state is generated and output to the horizontal display unit of the sensor unit. As a result, the user adjusts the inclination of the sensor unit so that the inclination sensor is in a substantially horizontal state while checking whether the inclination sensor is currently in a substantially horizontal state while viewing the display on the horizontal display unit. be able to.
