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. A drive adjustment unit that adjusts the launch strength of the game medium by the launching device, a launch biasing unit that biases the launch adjustment unit toward the reference position, and a drive that fixes the launch adjustment unit at a displaced position. And a launching operation device for causing the launching device to launch the game medium, and a control means for controlling the driving of the location fixing unit.

The game media can be launched into the game area while maintaining the intended launch strength while reducing the burden on the hand without the need for a force to play. Improve It can be.

  Further, the firing operation device can be displaced between an operation position for operating the control start operation means and a release position for releasing the operation of the control start operation means, and adjusts the launch while placing at least a part of the player's hand. Since it has a hand-mounted portion that enables the operation of the portion and a hand-mounted urging portion that urges the hand-mounted portion toward the release position, the hand-mounted portion is displaced to the operating position and is controlled by the control means. When the control start operating means for starting the control is operated, the driving of the position fixing unit is controlled by the control means, and the launch adjusting unit is urged toward the stop position where the launch of the game medium by the launching device is stopped Since the launch adjustment unit that adjusts the launch strength of the game medium by the launching device can be fixed at a displaced position against the bias of the player, the player places at least a part of the hand on the hand placement unit. While the launch adjustment part In addition to being able to perform the operation, it is possible to resist the biasing of the launching biasing part that biases the launching adjustment part toward the reference position by simply displacing the hand-mounted part to the operation position at the intended launching strength. Thus, it is possible to launch the game medium into the game area while maintaining the intended launch strength while reducing the burden on the hand without requiring the force to maintain the position of the launch adjustment unit. Thus, the operability during the game can be further improved. Further, since the hand-mounted portion is normally positioned at the release position by the urging of the hand-mounted urging portion, the hand-mounted portion can be positioned at the release position as long as the player does not displace the hand-mounted portion. Furthermore, since the player can operate the launch adjusting unit while placing at least a part of the hand on the hand placing unit, the player can play the game with a comfortable hand.

  Further, the position fixing unit includes a moving member that moves between a contact position that contacts the fixing member provided in the launch adjusting unit and a release position that releases the contact with the fixing member, and a movement driving unit that drives the moving member. The moving drive unit moves the moving member so that the moving member comes into contact with the fixed member, and resists the biasing of the launching biasing unit that biases the launching adjustment unit toward the reference position. Since the launch adjusting portion can be fixed at the displaced position by the contact resistance between the moving member and the fixed member, the configuration is simple and the manufacturing cost can be reduced.

  Further, the launch adjusting portion is provided with a magnetic member made of a magnetic material, and the position fixing portion is magnetized to hold the magnetic member and is demagnetized to release the magnetic member. With the magnetic part that changes to the launching adjustment part, the launching adjustment part resists the bias of the launching biasing part that biases the launching adjustment part toward the reference position simply by magnetizing the magnetic member and holding the magnetic member. Can be fixed at the displaced position, so that the launch adjusting portion can be easily fixed.

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 51, and the firing circuit 52 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 6 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 51. The rotation amount calculation unit 51 sends a corresponding voltage signal to the firing circuit 52 based on the rotation amount signal that has been sent. When the player touches the conductive ring holder 27, the contact detection processing unit 53 is energized through the ring holder 27, the contact detection ring 45, and the contact detection wire 44. The contact detection processing unit 53 sends a firing permission signal to the firing circuit 52 and a lock permission signal to the lock circuit 54 based on the energization. The firing circuit 52 sends a corresponding drive signal to the main CPU 15a based on the voltage signal sent from the rotation amount calculation unit 51 and the launch permission signal sent from the contact detection processing unit 53. 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. .

  When the player presses the lock switch 38 in a state in which the pachinko ball 7 is launched on the surface of the game board 4, a lock-on signal is sent to the lock circuit 54. The lock circuit 54 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 53 and the lock-on signal sent from the lock switch 38. The main CPU 15a energizes the main body 33a based on the received lock driving signal, and the energized main body 33a moves the driving iron core 33c in the direction A in FIG. 12 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 urging force of the torsion spring 41 that urges the ring holder 27 back to the reference position. growing. Thereby, the ring holder 27 is fixed so as not to rotate. When the player releases the press of the lock switch 38, the main CPU 15a stops energization of the main body 33a, and the main body 33a deenergized moves the driving iron core 33a in the direction B 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 presses the lock switch 38 during the game, the moved driving iron core 33c comes into contact with the rubber fixed plate 37 having a high friction coefficient attached to the ring holder 27, and the ring is caused by the contact resistance. Since the holder 27 is fixed so as not to rotate, it does not require a force to maintain the position of the ring holder 27 against the biasing of the torsion spring 41 that biases the ring holder 27 in the direction to return it to the reference position. Since the position of the ring holder 27 can be maintained only by pressing the lock switch 38, the burden on the player's hand can be reduced.

  FIG. 13 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. 13 (A), an iron arcuate plate-shaped fixing plate (magnetic member) 57 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 57 is attached so as to face the front end surface of the drive iron core 33c when the ring holder 27 is rotated to any position within the rotation range. When the player presses the lock switch 38, a lock-on signal is sent to the lock circuit 54. The lock circuit 54 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 53 and the lock-on signal sent from the lock switch 38. 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. 13B. The magnetized driving iron core 33c holds the fixed plate 57 by magnetism. Thereby, the ring holder 27 is fixed so as not to rotate. When the player releases the press of the lock switch 38, the main CPU 15a demagnetizes the drive iron core 33c. Thereby, the holding of the fixing plate 57 by the driving iron core 33a is released, and the fixing of the ring holder 27 is released. The fixing plate 57 is not limited to iron, and may be appropriately changed as long as it is a magnetic member. Preferably, a ferromagnetic member is used.

  Thus, the fixing plate 57 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 57 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. 14 shows another embodiment. Constituent members similar to those of the embodiment shown in FIGS. 1 to 12 are denoted by the same reference numerals, and detailed description thereof is simplified. In this embodiment, as shown in FIG. 14A, a substantially T-shaped fixed shaft 60 is attached to the ring holder 27 so that the center of rotation is the same as the center of rotation 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. 14A, 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 presses the lock switch 38, a lock-on signal is sent to the lock circuit 54. The lock circuit 54 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 53 and the lock-on signal sent from the lock switch 38. The main CPU 15a releases the energization to the magnetic coil 61d based on the received lock drive signal. When energization to the magnetic coil 61d is released and the magnetic coil 61 is made non-magnetic, as shown in FIG. 14B, the pressing plate 61b is moved in a direction in which the shaft main body 60a is pressed by the coil spring 61c. 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 41 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 press of the lock switch 38, 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 pressurize 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. 15 shows another embodiment. Constituent members similar to those of the embodiment shown in FIGS. 1 to 12 are denoted by the same reference numerals, and detailed description thereof is simplified. In this embodiment, as shown in FIG. 15 (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 (C direction and D 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 presses the lock switch 38, a lock-on signal is sent to the lock circuit 54. The lock circuit 54 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 53 and the lock-on signal sent from the lock switch 38. Based on the received lock drive signal, the main CPU 15a strikes the teeth of the second adjustment gear 32 in the direction pressing the teeth of the first adjustment gear 31 (C direction 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 press of the lock switch 38, the main CPU 15a has a striking strength 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 (D direction in the figure). The adjustment volume 30 is moved so that the first adjustment gear 31 is rotatable. 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. .

An insertion recess 26p for inserting the first arm portion 73b of the torsion spring 73 is formed on the lower surface of the spring locking portion 26o. On the right side surface of the shaft portion 26a, a convex receiving rib 26q serving as a receiving portion when the armrest 70 is rotated clockwise (F direction in FIG. 19), and a lock switch (control start operation means) 71 are provided. A convex plate-shaped switch mounting portion 26r for mounting is formed.

  As shown in FIGS. 18 to 20, the armrest (hand-held portion) 70 is formed in a substantially U shape, and has a plate-like main body portion 70 a, an opening 70 b, a left rotation shaft portion 70 c, and a right rotation shaft. Part 70d. The armrest 70 is rotatable between a pressing position (see FIG. 20) for pressing a push button 75 of a lock switch 71 described later (see FIG. 20) and a releasing position (see FIG. 19) for releasing the pressing of the push button 75. It is biased upward, which is a release position, by a torsion spring 73 described later. A line connecting the center of the left rotation shaft portion 70c and the center of the right rotation shaft portion 70d serves as a rotation center when the armrest 70 is rotated. An insertion hole 70e for inserting the rotation shaft 72 is formed in the left rotation shaft portion 70c and the right rotation shaft portion 70d, respectively. The left rotation shaft portion 70c is inserted into a center portion 73a of a torsion spring 73 described later, and the rotation shaft 72 is rotated on the left side surface of the insertion portion 70e of the left rotation shaft portion 70c and the shaft portion 26a of the handle base 26. When the hole 26n, the rotation hole 26n on the right side surface of the shaft portion 26a and the insertion hole 70e of the right rotation shaft portion 70d are inserted in this order, the armrest 70 is centered around the rotation shaft 72 on the shaft portion 26a of the handle base 26. Mounted in a rotatable state. A convex plate-like spring locking portion 70f for locking a second arm portion 73c of a torsion spring 73, which will be described later, is formed on the left side on the rear end side with respect to the central portion of the main body portion 70a. An insertion recess 70g for inserting the second arm portion 73c of the torsion spring 73 is formed on the lower surface of the spring locking portion 70f. A convex pressing portion 70h for pressing the push button 75 of the lock switch 71 is formed on the right rotation shaft portion 70d. The main body 70a of the armrest 70 is formed in a shape that fits a wrist that is a part of the player's hand (portion from the shoulder to the fingertip) without a sense of incongruity. As a result, the player can put the wrist on the main body 70a, put the palm on the face cover 28, and perform the rotation operation of the ring holder 27 with only the fingertip. be able to. The opening 70b is formed so that the main body 70a does not come into contact with the handle base 26, the ring holder 27, and the face cover 28 when the armrest 70 is rotated.

  As shown in FIG. 18, the torsion spring (hand-loaded biasing portion) 73 includes a central portion 73a wound in a coil shape, and first and second arm portions 73b and second extending linearly outward from the central portion 73a. It is comprised from the arm part 73c. When the first arm portion 73b is inserted into the insertion recess 26p of the spring locking portion 26o of the handle base 26 and the second arm portion 73c is rotated counterclockwise (E direction in the figure), the first arm portion 73b is counterclockwise. In the direction (E direction in the figure), a rotational force is generated to rotate the second arm portion 73c in the clockwise direction (F direction in the figure). When the second arm portion 73c is inserted into the insertion recess 70g of the spring locking portion 70f, the first arm portion 73b is locked to the spring locking portion 26o and the second arm portion 73c is locked to the spring locking portion 70f. The torsion spring 73 is fixed. As a result, the armrest 70 is biased upward (the F direction in the figure), which is the release position, by the torsion spring 73. Further, a convex engagement boss 70i is formed on the right rotation shaft portion 70d, and as shown in FIG. 19, this engagement boss 70i contacts the receiving rib 26q formed on the shaft portion 26a. By doing so, the rotation of the armrest 70 rotated in the F direction by the torsion spring 73 is stopped, and the armrest 70 is not further rotated in the F direction.

  As shown in FIG. 18, a lock switch (control start operation means) 71 is attached to a switch attachment portion 26r formed on the right side surface of the shaft portion 26a by an attachment member (not shown).
