Description

  The present invention relates to a ball game machine such as a pachinko machine that is installed and used in a game hall such as a pachinko shop.

  Currently, pachinko machines installed in amusement halls have an operation handle on the front. The operation handle is provided with a ring holder that can be rotated. When the ring holder is rotated, the rotation is transmitted to the ball launcher via the transmission unit, and the pachinko ball is played by the ball launcher. Launched into the area. When playing a game, the player turns a ring holder by a predetermined amount with one hand and launches a pachinko ball into the game area. This ring holder has a pachinko ball launch strength that changes in proportion to the amount of rotation. For this reason, the player adjusts the amount of rotation of the ring holder so as to achieve the intended launch strength.

  However, in the case of this operation handle, the ring holder is biased by a spring in a direction to return to the reference position where the pachinko ball is not launched. For this reason, in order to maintain the intended launch strength, holding the rotated ring holder at a fixed position against the biasing force of the spring is particularly handy for a player who plays a game for a long time. Will be burdensome. In this case, for example, it is conceivable that the game is resumed once the hand is released from the ring holder, but once the ring holder is released, the ring holder is in a state where the pachinko ball is not launched by the ball launcher. Therefore, it was necessary to adjust the launch strength by rotating the ring holder again, and the operability during the game was poor.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a ball game machine that can improve the operability in the game.

  In order to achieve the above object, a bullet ball game machine according to the present invention has a launch device that launches a game medium toward a game area, and an amount displaced from a reference position that is displaceable and non-displaced.

As a result, the support base 46 is rotatable about the rotation shaft 47. The support base 46 is inserted into the swing hole 6b, the support base 46 is inserted into the shaft portion 26b of the handle base 26, and the handle base 26 is attached to the support base 46 by an attachment member (not shown). As a result, the operation handle 8 has a pressing position (see FIG. 13) for pressing a push button 50 of a lock switch 48, which will be described later, and a release position (see FIG. 11) for releasing the pressing state about the rotation shaft 47. It can swing between. The operation handle 8 is normally biased upward, which is a release position, by a coil spring (operation biasing portion) 49 described later. In this embodiment, the support base 46 and the rotation shaft 47 function as a support portion that supports the operation handle 8 so as to be displaceable, and this support portion includes a coil spring 49 as an operation biasing portion. .

  As shown in FIG. 11, a lock switch (control start means) 48 is attached to the lower surface of the swing hole 6b, and this lock switch 48 is connected to a lock circuit 57 in the main control circuit device 15 described later. (See FIG. 14). A concave spring insertion recess 6c is formed on the lower surface of the swing hole 6b. The spring insertion recess 6c has a coil spring (operation biasing portion) for biasing the operation handle 8 upward (releasing position). 49) is inserted. The upper end portion of the coil spring 49 comes into contact with the lower surface of the shaft portion 26b of the handle base 26 and biases the handle base 26 upward, which is the release position. When the handle base 26 is biased upward, the upper side surface of the shaft portion 26b of the handle base 26 comes into contact with the upper side surface of the swing hole 6b. This prevents the handle base 26 from rotating any further. The lock switch 48 includes a push button 50, a guide button 51, a switch plate 52, and a switch board 53. The push button 50 is guided by a guide button 51 and is attached so as to be slidable in the vertical direction (A direction and B direction in the drawing). As shown in FIG. 13, when the operation handle 8 is swung downward as the lock position and the push button 50 of the lock switch 48 is pressed (slid in the A direction) by the support base 46, it is made of a thin metal that is elastically deformed. The switch plate 52 is deformed and comes into contact with the pattern surface 53 a of the switch substrate 53. The pattern surface 53a is provided with a pattern of an electric circuit, and is usually disconnected and not energized as shown in FIG. By bringing the switch plate 52 into contact with the pattern surface 53 a, the pattern is energized and a lock-on signal is transmitted to the lock circuit 57.

  As shown in FIG. 14, the operation of the pachinko machine 2 is basically controlled by the main control circuit device 15 and the sub control circuit device 16.

  The main control circuit device 15 includes a main CPU (central processing unit) 15a, a main ROM (read only memory) 15b, a main RAM (random access memory) 15c, a rotation amount calculation unit 54, a firing circuit 55, a contact detection processing unit 56, The lock circuit 57 is configured. The main CPU 15a reads a game control program stored in the main ROM 15b in response to an input signal input from the winning ball detection sensor 14 and generates a command for controlling the gaming state of the pachinko machine, and the sub control circuit device The command information is transmitted to 16 and executed so as to be in a predetermined gaming state. In the main ROM 15b, a game control program, a random number generation processing program, a random number table, and the like are stored in predetermined areas, and these are read out by the main CPU 15a and appropriately used so as to be processed. The main RAM 15c is a working area and is used for temporary storage or rewriting of data used in the game. In the present embodiment, the main CPU 15 a also functions as a control unit that controls the drive of the solenoid 33, and the rotation transmission unit (transmission unit) 34 that transmits the rotation of the ring holder 27 to the ball launcher 17 is the main CPU 15 a. The CPU 15 a, the launch strength adjustment volume 30, the first adjustment gear 31, the second adjustment gear 32, the rotation amount calculation unit 54, and the firing circuit 55 are configured.

  The sub control circuit device 16 includes a sub CPU 16a, a sub ROM 16b, and a sub RAM 16c. The sub CPU 16a appropriately reads out the control program for the sub control device stored in the sub ROM 16b, and according to the control signal input as command information from the main control circuit device 15, the sub control circuit device 16 and the sub control circuit device 16 Then, drive control is performed to input / output control signals among the symbol variable display device 9, the sound generation device 21, and the lamp 22 so as to enter a predetermined gaming state. The sub RAM 16c serves as a working area, and is used for temporary storage or rewriting of data used in the control of the symbol variable display device 9, the sound generator 21, and the lamp 22. The device for controlling the driving by the sub CPU 16a is not limited to the symbol variable display device 9, the sound generating device 21, and the lamp 22, and includes a movable winning device provided in the game area 4a.

  When the signal from the winning ball detection sensor 14 is input, the main CPU 15a drives the ball payout device 18 based on the game control program stored in the main ROM 15b to supply a predetermined number of winning balls on the supply tray 6a. Pay out. Note that the number of winning balls may be set as appropriate according to the type of each of the winning openings 10 to 12 containing gaming balls.

  The operation of the pachinko machine configured as described above will be described. The player rotates the ring holder 27 of the operation handle 8 and launches the pachinko ball 7 into the game area 4a by the ball launcher 17. When the ring holder 27 is rotated, the shaft 30c of the launch strength adjusting volume 30 is rotated via the first adjustment gear 31 and the second adjustment gear 32. The launch strength adjusting volume 30 sends a rotation amount signal corresponding to the rotation amount of the shaft 30 c to the rotation amount calculation unit 54. The rotation amount calculation unit 54 sends a corresponding voltage signal to the firing circuit 55 based on the rotation amount signal that has been sent. When the player touches the conductive ring holder 27, the contact detection processing unit 56 is energized through the ring holder 27, the contact detection ring 43, and the contact detection wire 42. The contact detection processing unit 56 sends a firing permission signal to the firing circuit 55 and a lock permission signal to the lock circuit 57 based on the energization. The firing circuit 55 sends a corresponding drive signal to the main CPU 15a based on the voltage signal sent from the rotation amount calculation unit 54 and the firing permission signal sent from the contact detection processing unit 56. Based on the drive signal sent, the main CPU 15a drives the ball launcher 17 to perform operation control for launching the pachinko ball 7 onto the game board 4 with a launch strength corresponding to the amount of rotation of the ring holder 27. .

  As shown in FIG. 13, when the player swings the operation handle 8 downward and presses the push button 50 of the lock switch 48 when the pachinko ball 7 has been launched on the surface of the game board 4, A lock-on signal is sent to the lock circuit 57. The lock circuit 57 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 56 and the lock-on signal sent from the lock switch 48. The main CPU 15a energizes the main body 33a based on the received lock drive signal, and the energized main body 33a moves the driving iron core 33c in the direction C in FIG. 15 as shown in FIG. To do. The moved driving iron core 33 c comes into contact with a fixed plate 37 attached to the ring holder 27. The fixed plate 37 is made of rubber having a high friction coefficient, and the contact resistance generated when the driving iron core 33c comes into contact is larger than the biasing force of the torsion spring 39 that biases the ring holder 27 in the direction to return to the reference position. growing. Thereby, the ring holder 27 is fixed so as not to rotate. When the player releases the swing of the operation handle 8, the operation handle 8 is biased upward (release position) by the coil spring 49, and the push button 50 of the lock switch 48 is released. When the push button 50 is released, the main CPU 15a stops energization of the main body 33a, and the main body 33a that is deenergized moves the driving iron core 33a in the direction D in FIG. Thereby, the contact with the fixing plate 37 of the drive iron core 33a is released, and the fixing of the ring holder 27 is released.

  In this way, when the player swings the operation handle 8 during the game and presses the push button 50 of the lock switch 48, the moved driving iron core 33c is attached to the ring holder 27 and made of a rubber having a high friction coefficient. The ring holder 27 comes into contact with the fixing plate 37 and the contact resistance fixes the ring holder 27 so as not to rotate. Therefore, the ring holder 27 resists the bias of the torsion spring 39 that biases the ring holder 27 back to the reference position. Since the position of the ring holder 27 can be maintained simply by rotating the operation handle 8 and pressing the lock switch 48 without requiring a force to maintain the position of the player, the burden on the player's hand is reduced. can do.

  FIG. 16 shows another embodiment. Constituent members similar to those in the above embodiment are given the same reference numerals, and the detailed description thereof is simplified. In this embodiment, as shown in FIG. 16 (A), an iron arcuate plate-shaped fixing plate (magnetic member) 59 made of a ferromagnetic material is driven on the back surface of the main body 27 a of the ring holder 27 to drive the solenoid 33. It is attached to a position facing the tip surface of the iron core 33c. The fixing plate 59 is attached so as to face the tip surface of the drive iron core 33c when the ring holder 27 is rotated to any position within the rotation range. When the player swings the operation handle 8 and presses the push button 50 of the lock switch 48, a lock-on signal is sent to the lock circuit 57. The lock circuit 57 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 56 and the lock-on signal sent from the lock switch 48. Based on the received lock drive signal, the main CPU 15a magnetizes the drive iron core 33c as a magnetic part, as shown in FIG. The magnetized drive iron core 33c holds the fixed plate 59 by magnetism. Thereby, the ring holder 27 is fixed so as not to rotate. When the player releases the swing of the operation handle 8, the operation handle 8 is urged upward (release position) by the coil spring 49 to release the push button 50 of the lock switch 48. When the push button 50 is released, the main CPU 15a demagnetizes the drive iron core 33c. Thereby, the holding of the fixing plate 59 by the driving iron core 33a is released, and the fixing of the ring holder 27 is released. The fixing plate 59 is not limited to iron, and may be appropriately changed as long as it is a magnetic member. Preferably, a ferromagnetic member is used.

  In this way, the fixing plate 59 is attached to the back surface of the main body 27a of the ring holder 27, the driving iron core 33c is magnetized, and the fixing plate 59 is held by the magnetism of the magnetized driving iron core 33c. Since the holder 27 can be fixed so as not to rotate, the ring holder 27 can be easily fixed.

  FIG. 17 shows another embodiment. Constituent members similar to those of the embodiment shown in FIGS. 1 to 15 are denoted by the same reference numerals, and the detailed description thereof is simplified. In this embodiment, as shown in FIG. 17A, a substantially T-shaped fixed shaft 60 is attached to the ring holder 27 so that the rotation center thereof is the same as the rotation center of the ring holder 27. It has been. The fixed shaft 60 includes a columnar shaft main body 60 a serving as a rotation center and a columnar base portion 60 b. The shaft main body 60 a is smaller than the diameter of the insertion hole 27 m, and the base portion 60 b is the ring holder 27. The diameter is larger than the insertion hole 27m, and the base portion 60b prevents the shaft main body 60a from being inserted through the insertion hole 27m. Then, the base portion 60 b is attached to the center boss 27 i of the ring holder 27 by an attachment member (not shown). An electromagnetic brake (position fixing portion) 61 is disposed in the handle base 26, and a shaft body 60a of the fixed shaft 60 is rotatably inserted into the electromagnetic brake 61. The electromagnetic brake 61 includes a main body 61a, an iron pressure plate (pressure member) 61b that is a ferromagnetic material, a coil spring 61c, and a magnetic coil (pressure drive unit) 61d. The magnetic coil 61d is connected to the main CPU 15a. ing. The pressure plate 61b is movably provided on the main body 61a, and is urged in a direction to pressurize the shaft main body 60a by a coil spring 61c.

  The magnetic coil 61d is normally energized and magnetized, and as shown in FIG. 17A, the pressurizing plate 61b is moved to a position where the shaft main body 60a is not pressed against the bias of the coil spring 61c by magnetism. keeping. When the player swings the operation handle 8 and presses the push button 50 of the lock switch 48, a lock-on signal is sent to the lock circuit 57. The lock circuit 57 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 56 and the lock-on signal sent from the lock switch 48. The main CPU 15a releases the energization to the magnetic coil 61d based on the received lock drive signal. When the energization of the magnetic coil 61d is released and the magnetic coil 61 is demagnetized, the pressurizing plate 61b is moved in the direction of pressurizing the shaft body 60a by the coil spring 61c as shown in FIG. The moved pressure plate 61b contacts and pressurizes the shaft body 60a. In the coil spring 61c, the contact resistance with the pressure plate 61b generated in the shaft main body 60a pressurized by the pressure plate 61b is larger than the urging force of the torsion spring 39 that urges the ring holder 27 in the direction to return to the reference position. As described above, the spring load is adjusted, and the pressure plate 61b prevents the shaft body 60a from rotating. Thereby, the ring holder 27 is fixed so as not to rotate. When the player releases the swing of the operation handle 8, the operation handle 8 is urged upward (release position) by the coil spring 49 to release the push button 50 of the lock switch 48. When the push button 50 is released, the main CPU 15a energizes the magnetic coil 61d to magnetize the magnetic coil 61d, and holds the pressure plate 61b at a position where it does not press the shaft body 60a. Thereby, the pressure applied to the shaft main body 60a by the pressure plate 61b is released, and the fixation of the ring holder 27 is released. Further, instead of attaching the fixed shaft 60 to the ring holder 27, a cylindrical shaft may be provided at the center of rotation of the ring holder 27.

  In this way, the fixed shaft 60 is attached to the ring holder 27, the energization to the magnetic coil 61d is released, and the pressure plate 61b is moved in the direction in which the shaft main body 60a is pressed by the coil spring 61c to pressurize the shaft main body 60a. Since the ring holder 27 can be fixed so as not to rotate by preventing the rotation of the shaft body 60a, the ring holder 27 can be fixed at a position away from the ring holder 27. A case where there is no space between the ring holder 27 and the handle base 26 can also be handled.

  FIG. 18 shows another embodiment. Constituent members similar to those of the embodiment shown in FIGS. 1 to 15 are denoted by the same reference numerals, and the detailed description thereof is simplified. In this embodiment, as shown in FIG. 18 (A), the launching strength adjusting volume 30 has a first adjusting gear 31 axis and a second adjusting gear in a direction perpendicular to the first adjusting gear 31 axis. It is provided so as to be movable in a direction (E direction and F direction in the figure) on a line connecting 32 axes, and is connected to the main CPU 15a. Thus, in this embodiment, the launch strength adjusting volume 30 also functions as a moving pressing unit. When the player swings the operation handle 8 and presses the push button 50 of the lock switch 48, a lock-on signal is sent to the lock circuit 57. The lock circuit 57 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 56 and the lock-on signal sent from the lock switch 48. Based on the received lock drive signal, the main CPU 15a ejects the teeth of the second adjustment gear 32 in the direction pressing the teeth of the first adjustment gear 31 (direction E in the figure) as shown in FIG. The strength adjustment volume 30 is moved, and the teeth of the second adjustment gear 32 are pressed against the teeth of the first adjustment gear 31 to make the first adjustment gear 31 unrotatable. Thereby, the ring holder 27 is fixed so as not to rotate. When the player releases the swing of the operation handle 8, the operation handle 8 is urged upward (release position) by the coil spring 49 to release the push button 50 of the lock switch 48. When the pressing of the push button 50 is released, the main CPU 15a sets the launching strength adjustment volume 30 in the direction opposite to the direction in which the teeth of the second adjustment gear 32 are pressed against the teeth of the first adjustment gear 31 (F direction in the figure). The first adjustment gear 31 can be rotated by moving. Thereby, the fixation of the ring holder 27 is released.

  In this way, the launch strength adjusting volume 30 is moved in a direction perpendicular to the axis of the first adjustment gear 31 in a direction on a line connecting the axis of the first adjustment gear 31 and the axis of the second adjustment gear 32. The punching strength adjusting volume 30 is moved in the direction in which the teeth of the second adjustment gear 32 are pressed against the teeth of the first adjustment gear 31, and the teeth of the second adjustment gear 32 are moved to the teeth of the first adjustment gear 31. The ring holder 27 can be fixed in a non-rotatable manner by making the first adjustment gear 31 non-rotatable by pressing against the ball launching device 17. The launch strength adjusting volume 30, the first adjusting gear 31, and the second adjusting gear 32 can be used when fixing the ring holder 27, and the number of parts and the manufacturing cost can be reduced. .
