Description

  The present invention relates to a ball game machine such as a pachinko machine installed in a game hall such as a pachinko parlor.

  Pachinko machines can be cited as bullet ball machines installed in game halls such as pachinko parlors. This pachinko machine has a game area where a pachinko ball is launched, and a guide passage that is provided along a part of the outer periphery of the game area and guides the pachinko ball launched during the game toward the upper part of the game area. The formed game board is assembled to the main body member. The front surface of the game board is covered with a front door that holds a glass plate, thereby preventing the pachinko ball flowing down the game area or the pachinko ball passing through the guide passage. For example, in the game area, a plurality of nails, structures such as a windmill and a center accessory, and a winning device such as a winning chucker, starter chucker, and attacker are provided. When a pachinko ball enters these winning devices, a prize is awarded, and a predetermined number of pachinko balls can be obtained as prize balls for winning. A certain value is given to the pachinko ball, and the pachinko ball acquired by playing a game can be exchanged for various prizes.

  The pachinko machine described above includes a launcher that launches pachinko balls one by one in the game area, and a ball feeder that feeds the pachinko balls one by one into the launcher. The launching device includes a loading unit in which a pachinko ball to be sent by the ball feeding device is set, a knock arm that strikes the pachinko ball set in the loading unit and launches it toward the game area, a rotary solenoid that rotates the knock arm, and the like Drive source. For example, when playing a game in a pachinko machine, the operation of the knock arm is performed by operating the drive source by operating the operation handle provided on the front surface of the pachinko machine. Sometimes a pachinko ball set in the loading section is launched toward the game area. Then, after the pachinko ball is launched, the ball feeding device is operated to feed a new pachinko ball into the loading unit. As a result, the pachinko ball launching operation is executed smoothly and at predetermined intervals.

  In a pachinko machine equipped with such a launching device and a ball feeding device, the above-described launching device is generally incorporated in a main body member. On the other hand, the ball feeding device has various forms such as those assembled to the launching device and those assembled to the lower unit assembled to the main body member. For example, when the launcher is assembled to the main body member and the ball feeding device is assembled to the lower unit, the launcher is exposed by simply removing the lower unit from the main body member. There is an advantage that can be done.

  On the other hand, when the ball feeder is assembled to the launcher, there are the following methods. For example, when a pachinko ball is fed by a ball feeding device in a direction substantially orthogonal to the game board surface (for example, from the player side toward the game board side), the ball feeding device is arranged closer to the player side than the launching device. Will be. In this case, when performing maintenance of the launching device, it is necessary to remove the ball feeding device once, so that a ball feeding device that is pivotally supported with respect to the launching device has been proposed (Patent Literature). 1). According to this, it is not necessary to remove the ball feeding device from the launching device at the time of maintenance of the launching device, and the workability at the time of maintenance can be improved.

However, when the pachinko ball is sent in a direction substantially orthogonal to the game board surface (for example, from the player side toward the game board side), the sent pachinko ball often swings with respect to the feed direction, There is a problem that it is difficult to stably launch a pachinko ball. For this reason, for example, it has been proposed to send pachinko balls from the upstream side in the launch direction of the pachinko balls (Patent Document 2). As a result, swinging in a direction substantially perpendicular to the launch direction is prevented, so that stable pachinko balls can be launched.
JP 2005-152247 A JP 2004-313244 A

  When the pachinko ball is fed from the upstream side in the launch direction described above, the ball feeding device is arranged above the launch rail and at a larger interval than the diameter of the pachinko ball. In this case, the pachinko ball fed by the ball feeding device is supported by two points of the launch rail and the ball stopper. In this case, the pachinko ball launched by the launcher is launched along the launch rail. However, if the ball feeder and the launch rail are incorporated with their relative positions shifted, they are launched along the launch rail. As a result, there is a problem that stable pachinko balls cannot be launched.

Has been.

  Further, the front surface 70c of the case 70 is provided with a rectangular tube portion 80 whose front surface protruding from the front surface 70c is closed. An opening 81 is provided on the upper surface 80 a of the cylindrical portion 80. The opening 81 communicates with the opening 27 formed in the passage forming portion 21 that forms the downstream end portion of the feeding passage 15 when the lower door 5 is closed, and the pachinko that is guided through the feeding passage 15. The ball 110 is fed into the ball feeder 65 through the opening 81. Hereinafter, the opening 81 will be described as an inflow port (receiving port) 81. A substantially L-shaped feed passage 82 that connects the inflow port 81 and the discharge port 76 is provided inside the case 70. An opening 83 is provided in the lower surface of the bent portion of the feed passage 82, and the ball feed blade 90 of the feed mechanism 71 enters the inside of the feed passage 82 through the opening 83.

  The delivery mechanism 71 includes a ball feed blade 90 and a solenoid 91. The ball feed blade 90 is provided with an insertion hole 90a at one end thereof, and the rotation shaft 85 provided in the case 70 is inserted into the insertion hole 90a, so that the ball feed blade 90 protrudes into the feed passage 80, and enters the feed passage 82. A position for preventing the pachinko ball 110 from rolling (hereinafter, solid line in FIG. 5) and a position for feeding the pachinko ball 110 in the feed passage 82 toward the discharge port 76 (hereinafter, two-dotted line in FIG. 5). Rotate between. The ball feeding blade 90 includes a connecting pin 95 that connects the ball feeding blade 90 and the solenoid 91 by being held by a holding portion 102 provided at the tip of the driving iron core 100 of the solenoid 91. Reference numeral 96 denotes a seat protruding from the peripheral wall surface of the ball feeding blade 90, and a connecting pin 95 is provided on the seat 96.

  The solenoid 91 includes a driving iron core 100 and a bobbin 101. The driving iron core 100 is provided with a holding portion 102 that holds the connecting pin 95 at the tip thereof. The holding portion 102 is formed in a substantially U-shape and includes two holding pieces 102 a and 102 b that are spaced apart from each other in the longitudinal direction of the driving iron core 100. By inserting the connecting pin 95 between the sandwiching pieces 102a and 102b, the driving iron core 100 and the connecting pin 95 are connected. The solenoid 91 is controlled to be powered and stopped by the control device 60.

  The driving iron core 100 is urged in the direction D in FIG. 5 by the urging of the coil spring 103 in a state where the power supply by the control device 60 is stopped. As a result, the ball feed blade 90 is held in a state of being in contact with the peripheral portion 83 b of the opening 83 provided in the feed passage 82. When power is supplied to the solenoid 91 by the control device 60, the driving iron core 100 is drawn into the bobbin 101 (moves in the direction E in FIG. 5). Since the holding portion 102 provided on the driving iron core 100 is connected to the connecting pin 95 of the ball feeding blade 90, when the driving iron core 100 is drawn into the bobbin 101, the ball feeding blade 90 is shown in FIG. It rotates in the middle F direction. Then, when the peripheral wall surface of the ball feeding blade 90 comes into contact with the stopper 105 provided on the case 70, the rotation is stopped and held at the position indicated by the two-dot chain line in FIG.

  On the other hand, when the power supply to the solenoid 91 is stopped, the driving iron core 100 is pulled out from the bobbin 101 by the urging of the coil spring 103 (moves in the direction D in FIG. 5). Rotate in the direction. When the peripheral wall surface of the ball feeding blade 90 comes into contact with the peripheral edge 83b of the opening 83, the rotation is stopped and held at the position indicated by the solid line in FIG. The pachinko ball 110 inside the feed passage 82 rolls toward the discharge port 76 by the rotation of the ball feed blade 90 and is discharged from the discharge port 76 to the ball receiving portion 77. Note that the pachinko ball 110 remaining inside the cylindrical portion 80 can be recovered by moving the recovery shutter 107 linked in accordance with, for example, an operation of a player or the like in the J direction in FIG.

  Next, the operation of this embodiment will be described. When the player operates the operation handle, the control unit performs power supply to the rotary solenoid 56 and stops power supply so that the launch strength according to the operation amount of the operation handle 10 is obtained. When power is supplied to the rotary solenoid 56 for a predetermined time, the drive shaft 56a of the rotary solenoid 56 rotates, so that the knock arm 55 fixed to the drive shaft 56a rotates in the direction B in FIG. After the knock arm 55 rotates, immediately before the short piece 55b of the knock arm 55 comes into contact with the first stopper 51, the tip of the launch bar 61 enters the inside through a slit 78 provided in the ball receiving portion 77, The ball contacts the pachinko ball 110 set on the ball receiving portion 77. Thereby, the pachinko ball 110 is launched. The launched pachinko ball 110 is moved toward the game area 32 via the launch passage 62. Thereafter, when the power supply to the rotary solenoid 56 is stopped, the knock arm 55 that is in contact with the first stopper 51 rotates in the direction C in FIG. During this rotation, the long piece 55a of the knock arm 55 is brought into contact with the second stopper 52, and the rotation of the knock arm 55 is stopped.

  After the power supply to the rotary solenoid 56 is stopped, the control device 60 supplies power to the solenoid 101 of the ball feeding device 65. With this power supply, the ball feed blade 90 rotates in the direction F in FIG. As a result, the ball feed blade 90 is retracted from the feed passage 82, so that the pachinko ball 110 whose rolling has been stopped rolls toward the discharge port 76 by the ball feed blade 90. Thereafter, when the power supply to the solenoid 101 is stopped, the ball feed blade 90 rotates in the direction G in FIG. 5 and enters the feed passage 82 to stop the pachinko ball 110 inside the feed passage 82. Thereby, only the pachinko ball 110 on the downstream side rolls to the discharge port 76 and falls from the discharge port 76 to the ball receiving portion 77.

  The pachinko ball 110 that has fallen on the ball receiving portion 77 swings inside the ball receiving portion 77, but since the ball receiving portion 77 is inclined toward the side surface 70 b of the case 70, the pachinko ball 110 is moved to the case 70. It will be in the state contact | abutted to the side surface 70b. Thereby, the pachinko ball 110 is set at the launch position. In addition, since the slit 78 is formed in the ball receiving portion 77, a part of the pachinko ball 110 that has fallen into the ball receiving portion 77 enters the slit 78, so that the pachinko ball 110 is positioned in the front-rear direction. As a result, when the launching device is driven, the launched pachinko ball 110 is stably launched. When the operation handle 10 is operated, the launching device 45 and the ball feeding device 65 described above are alternately operated, so that the pachinko balls 110 are continuously launched toward the game area 32.

  For example, when the maintenance of the launching device 45 and the ball feeding device 65 is performed, the store clerk at the game hall opens the upper door 4 and the lower door 5. For example, when the lower door 5 is opened, the space between the back surface 5a of the lower door 5 and the cylindrical portion 80 of the ball feeding device 65 widens, so that the shutter 25 urged by the coil spring 26 protrudes and enters the passage forming portion 21. The provided opening 27 is shielded (see FIG. 7). Thereby, for example, it is not necessary to drop the pachinko ball 110 located inside the feeding passage 15 onto the floor of the game hall.

  After the maintenance of the launching device 45 and the ball feeding device 65 is completed, when the lower door 5 is closed, the shutter 25 is brought into contact with the cylindrical portion 80 of the ball feeding device 65 and the movement of only the shutter 25 is restricted. As a result, the relative position between the opening 27 of the passage forming portion 21 and the shutter 25 changes, and the opening 27 is exposed. When the opening 27 is exposed, the inflow port 81 formed on the upper surface 80a of the cylindrical portion 80 of the ball feeder 65 and the opening 27 of the passage forming portion 21 are communicated (see FIG. 6). Thereby, the pachinko ball 110 located on the downstream side of the feeding passage 15 falls into the cylindrical portion 80, that is, into the feeding passage 82.

  In the present embodiment, the lower door that rotates with respect to the main body member is taken as an example of the lower unit, but the present invention is not limited to this, and may be, for example, a lower unit that is assembled to the main body member.
