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.

  Such a pachinko machine includes a launching device that launches pachinko balls one by one in the game area, and a ball feeding device that feeds the pachinko balls one by one into the launching device. Such a launching device includes a loading unit in which a pachinko ball to be sent by a ball feeding device is set, a knock arm that strikes the pachinko ball set in the loading unit and launches it toward a game area, and rotates the knock arm It has a rotary solenoid. For example, when playing a game in a pachinko machine, by operating the operation handle provided on the front surface of the pachinko machine, the launching of the pachinko ball by the above-described launching device and the feeding of the pachinko ball by the ball feeding device are executed. Is done. Thus, when the operation handle is operated, the pachinko balls are launched into the game area at regular intervals.

  Such an operation handle is configured such that the launch strength of the game ball by the launching device can be changed depending on the operation amount. For this reason, for example, immediately after the operation of the operation handle is started or when the operation amount of the operation handle is changed by mistake, the momentum of the pachinko ball launched by the launching device is weak, and the guide passage is not reached without reaching the game area. It may become a so-called foul sphere that falls (backflow) inside. In the case of a pachinko machine, pachinko balls are launched at regular intervals. Therefore, when a foul ball is generated, clogging due to the foul ball is likely to occur. For this reason, as a method for preventing ball clogging caused by foul balls, pachinko machines are often provided with a collection port for collecting generated foul balls (Patent Document 1). However, even if such a recovery port is provided, there is a foul ball that falls into the launching device without being recovered by the recovery port, and as a result, there is a problem that clogging of the foul ball cannot be eliminated. .

As a method for solving such a problem, for example, a leaf spring for blocking the loading unit is provided above the loading unit of the launching device described above, and a foul ball falling into the launching device is dropped along the leaf spring. It has been devised to collect a foul ball by a collection port provided inside the launching device (Patent Document 2). According to this, since the foul sphere does not enter the loading portion, the clogging caused by the foul sphere is eliminated.

  The first stopper 52 is brought into contact with the short piece 50b of the knock arm 50 that rotates in the direction A in FIG. 3 when power is supplied to the rotary solenoid 51, whereby the first arm 52 of the knock arm 50 in the direction A in FIG. It is provided to prevent rotation. When the knock arm 50 comes into contact with the first stopper 52, the pachinko ball 100 loaded in the loading portion 54 is launched by the launch bar 50c provided on the long piece 50a of the knock arm 50. Hereinafter, the position of the knock arm 50 when the knock arm 50 is brought into contact with the first stopper 52 will be described as the hitting position.

  When the power supply to the rotary solenoid 51 is stopped, the second stopper 53 contacts the long piece 50a of the knock arm 50 that rotates in the direction B in FIG. The position of the knock arm 50 when the knock arm 50 is brought into contact with the second stopper 53 will be described as an initial position.

  The loading portion 54 includes a first component member 60 and a second component member 61, and the interval between the component members 60 and 61 is wider than the diameter of the launch bar 50 c of the knock arm 50, and the diameter of the pachinko ball 100. The base member 55 is assembled with a narrower width. Further, the space formed between the first component member 60 and the second component member 61 is on the rotation trajectory of the launch bar 50c of the knock arm 50 (the trajectory indicated by the two-dot chain line in FIG. 5). The base plate 55 is assembled so as to be positioned. As a result, the pachinko ball 100 fed from the ball feeding device 85 rotates the launch bar 50c of the knock arm 50 while being held in contact with the first component member 60 and the second component member 61, respectively. It is set (loaded) on the track.

  The first component member 60 is provided with a recess 62 in a wall surface 60 a facing the second component member 61, and the recess 62 allows the pachinko ball 100 fed from the ball feeding device 85 to strike the knock arm 50. It is provided for setting on the rotation trajectory of 50c.

  In the base plate 55, the rotary solenoid 51, the first stopper 52, the second stopper 53, and the loading portion 54 described above are fixed by screws or the like. A square-shaped opening 65 is provided in the base plate 55 at a location between the first component member 60 and the second component member 61 constituting the loading unit 54. The opening 65 is a collection port (hereinafter referred to as a collection port 65) for collecting the pachinko ball 100 loaded in the loading unit 54.

  An opening / closing mechanism 56 for opening / closing the recovery port 65 described above is assembled on the side of the base plate 55 where the rotary solenoid 51 is assembled. The opening / closing mechanism 56 includes a shutter 70, a winding spring (biasing means) 71, and a solenoid 72. The shutter 70 includes a rotating plate 73 and a support plate 74, and these plates are connected via pins 75. The rotation plate 73 is composed of a plate having an area slightly smaller than the size of the recovery port 65 provided in the base plate 55, and a position (a position indicated by a solid line in FIG. 4) that shields the recovery port 65 and a recovery port. It is possible to rotate between a position where 65 is opened (a position indicated by a two-dot chain line in FIG. 4). A bearing portion 76 through which the pin 75 is inserted is provided at one end edge portion of the rotating plate 73 with a predetermined interval. The support plate 74 is fixed to the base plate 55. A bearing portion 78 positioned outside the bearing portion 76 provided on the rotating plate 73 is provided at one end edge portion of the support plate 74.

  The pin 75 is inserted through the bearing portions 76 and 78, thereby connecting the rotating plate 73 and the support plate 74. The pin 75 is inserted into a winding spring 71 disposed in a space provided between the bearing portions 76 of the rotating plate 73 when the rotating plate 73 and the support plate 74 are connected. Hold.

  The winding spring 71 is held between the bearing portions 76 of the rotating plate 73. One end 71 a of the winding spring 71 is in contact with the support plate 74, and the other end 71 b is engaged with an engagement piece 73 a provided on the rotating plate 73. As a result, the rotating plate 73 is biased in the direction of opening the recovery port 65 (in the direction C in FIG. 4) by the bias of the winding 71 spring.

  The solenoid 72 includes a bobbin 80 and a driving iron core 81 and presses the rotating plate 73 in a direction to shield the recovery port 65. The solenoid 72 is held in a state where the driving iron core 81 is pulled out from the bobbin 80 by a spring (not shown). When power is supplied to the solenoid 72, the driving iron core 81 is drawn into the bobbin 80. For example, when power is not supplied to the solenoid 72, the rotating plate 73 is pressed by the tip of the driving iron core 81, and the rotating plate 73 is held at a position where the collecting port 65 is shielded. As described above, when power is supplied to the solenoid 72, the driving iron core 81 is drawn into the bobbin 80. Therefore, the rotating plate 73 is rotated in the direction C in FIG. 65 is opened.

  The ball feeding device 85 feeds the pachinko balls 100 in the feeding passage 15 one by one into the loading unit 54 of the launching device 45. The ball feeding device 85 includes an introduction opening 86 and a delivery opening 87, and the pachinko ball 100 located at the downstream end of the feeding passage 15 is introduced into the ball feeding device 85 from the introduction opening 86. After receiving one ball at a time, the balls are sent out from the delivery opening 87 toward the loading portion 54 of the launching device 45 one by one. The ball feeding device 85 is assembled on the back side of the lower door 5, and when the lower door 5 is closed, the delivery opening 87 of the ball feeding device 85 and the first component member 60 provided in the launching device 45. The recess 62 is positioned so as to face each other.

  Between the loading unit 54 of the launching device 45 and the guide passage 31, there is provided a launching passage 90 that guides the pachinko ball 100 launched from the loading unit 54 to the guide passage 31. A detection sensor (ball detection means) 91 for detecting the pachinko ball 100 passing therethrough is disposed in the launch passage 90. The detection sensor 91 is provided with, for example, a reflective photosensor. When the pachinko ball 100 is detected by the detection sensor 91, the detection signal is output to the launch control device 92. In response to the output of the detection signal, the launch control device 92 performs drive control of the opening / closing mechanism 56 and the ball feeding device 85 assembled to the launch device 45. In addition, the code | symbol 93 shown in FIG. 5 is a decoration.

  The launch control device (drive control device) 92 is provided to drive and control the launch device 45 and the ball feeding device 85. For example, when the operation handle 10 is operated, the value of the launch volume 94 provided inside the operation handle 10 changes, so that the rotary strength is set so that the launch strength is based on the value of the launch volume 94. The solenoid 51 is driven and controlled. When the rotary solenoid 51 is driven, the ball feeding device 85 is driven to feed the pachinko ball 100 into the launching device 45.

  The launch control device 92 includes a state determination unit 95. The state determination unit 95 is provided to determine whether power supply to the rotary solenoid 51 and output of a detection signal from the detection sensor 91 are alternately performed. For example, when power feeding to the rotary solenoid 51 and output of a detection signal from the detection sensor 91 are alternately performed, the pachinko ball 100 launched by the launching device 45 is launched to the game area 30. It is determined that the state is normal. On the other hand, for example, when the detection signal from the detection sensor 91 is output again after the detection signal from the detection sensor 91 is output until the power is supplied, the detection signal from the detection sensor 91 is not interrupted. If the pachinko ball 100 that has been launched does not reach the game area 30, a so-called foul ball has fallen into the launching device 45, or the launch passage 90. It is determined that the foul ball is clogged. When the state determination unit 95 determines that the state is abnormal, the launch control device 92 supplies power to the solenoid 72 and stops driving the ball feeding device 85. Thereby, the collection port 65 is opened by the opening / closing mechanism, and after the pachinko ball 100 in the launch passage 90 or the pachinko ball 100 set in the loading portion 54 rolls in the collection passage 46 from the collection port 65, It is paid out to the auxiliary tray 12.

  Next, the effect | action of this embodiment is demonstrated based on the flowchart of FIG. When the player operates the operation handle 10 after supplying the pachinko ball 100 to the supply tray 11, the firing control device 92 moves to the rotary solenoid 51 of the launching device 45 so that the launching strength matches the launching volume 94. Supply power. By this power supply, the drive shaft 51a of the rotary solenoid 51 rotates, and the knock arm 50 at the initial position rotates toward the launch position. When the knock arm 50 rotates to the launch position, the launch bar 50c of the knock arm 50 comes into contact with the pachinko ball 100 set in the loading unit 54, and the pachinko ball 100 set in the loading unit 54 is launched. At this time, the launch control device 92 stops power supply to the rotary solenoid 51.

  On the other hand, the pachinko ball 100 launched by the launcher 50 c of the knock arm 50 passes through the launch passage 90 and the guide passage 31 and is launched into the game area 30. When the pachinko ball 100 passes through the launch passage 90, the pachinko ball 100 is detected by the detection sensor 91, and the detection signal is output to the launch control device 92. Since the firing control device 92 operates the state determination unit 95 when the operation handle 10 is operated, the state determination unit 95 outputs a detection signal from the detection sensor 91 and a drive signal of the rotary solenoid 51. It is determined whether or not the normal state is performed alternately.

  As shown in FIG. 7A, when the detection signal is output from the detection sensor after the rotary solenoid drive signal is output, the state determination unit 95 determines that the state is normal. The In this case, the firing control device 92 operates the ball feeding device 85 to feed one pachinko ball 100 located at the downstream end of the feeding passage 15 into the launching device 45. Thereby, when the operation handle 10 is operated, the above-described operation is repeated.

  For example, when the value of the launch volume 94 changed by the operation of the operation handle 10 is small, the pachinko ball 100 launched by the knock arm 50 falls through the guide passage 31 without reaching the game area 30, that is, a foul ball. . In this case, pachinko balls that become foul balls are collected by the collection openings 41 and 42 shown in FIG. However, there are pachinko balls 100 that fall into the launch path 90 in the pachinko balls 100 that become foul balls. In this case, as shown in FIG. 7B, when the pachinko ball 100, which is a foul ball, falls into the launch passage 90, the drive signal of the rotary solenoid 51 is output and then the next drive signal is output. In the meantime, the detection sensor 91 detects twice. That is, after being detected by the detection sensor 91 when the pachinko ball 100 is launched, it is detected again by the detection sensor 91 when the launch passage 90 is dropped. In this case, the state determination unit 95 determines that the state is abnormal, and supplies power to the solenoid 72 that is the opening / closing mechanism 56.

  As shown in FIGS. 8 and 9, the drive iron core 81 of the solenoid 72 is drawn into the bobbin 80 (in the F direction in FIG. 8) by supplying power to the solenoid 72. The rotating plate 73 of the shutter 70 is rotated by a biasing force of the winding spring 71 from a position where the recovery port 65 is shielded to a position where the recovery port 65 is opened (in the G direction in FIG. 8). Thereby, the collection port 65 is opened, and the pachinko ball 100 located in the loading unit 54 is collected from the collection port 65. The pachinko balls 100 collected from the collection port are paid out to the auxiliary tray 12 via the collection passage 46. Further, the launch control device 92 supplies power to the solenoid 72 and stops driving the ball feeding device 85 at the same time. Thereby, since the pachinko ball 100 is not fed into the launching device 45, the pachinko ball 100 is not set in the loading portion 54 of the launching device 45. As described above, since the processing for the foul ball can be automatically performed by detecting the pachinko ball 100 falling in the launch passage 90 among the foul balls, it is possible to prevent clogging of the ball that occurs when the pachinko ball is launched. .

  Note that when a predetermined time elapses, for example, 10 seconds after it is determined to be in an abnormal state, power supply to the solenoid 72 by the firing control device 92 is stopped. When the power supply to the solenoid 72 is stopped, the driving iron core 81 moves in the direction protruding from the bobbin 80 (in the H direction in FIG. 9), and presses the rotating plate 73 that opens the recovery port 65. . In response to this pressing, the rotating plate 73 rotates in the direction I in FIG. 9 and shields the recovery port 65. After the collection port 65 is shielded, the launch control device 92 operates the ball feeding device 85 to feed the pachinko ball 100 into the launch device 45. Thereby, the pachinko ball 100 is set in the loading portion 54 of the launching device 45. When the operation handle 10 is operated, for example, the launch of the pachinko ball 100 is resumed.

  In addition, as shown in FIG. 7C, when the detection signal from the detection sensor 91 is continuously performed, the pachinko ball 100 is filled from the loading portion 54 to the launch passage 90. . Also in this case, since the state determination unit 95 determines that the state is abnormal, the recovery port 65 is opened by the above-described operation, and the pachinko balls 100 that cause the clogging of the balls are recovered and delivered to the auxiliary tray 12. Thereby, it is possible to eliminate the ball clogging that occurs when the momentum of the pachinko ball 100 launched by the knock arm 50 is very small.

  In the present embodiment, the detection sensor that detects the pachinko ball 100 passing through the launch passage 90 is provided at one location. However, the present invention is not limited to this, and two detection sensors provided in the launch passage 90 are provided. It is good also as above. Hereinafter, portions having the same functions as those of the present embodiment will be described with the same reference numerals. As shown in FIG. 10, when two detection sensors are provided, the detection sensors 105 and 106 are installed along the longitudinal direction of the launch passage 90 and at a predetermined interval. The predetermined interval is preferably a width wider than the diameter of one pachinko sphere 100. In this case, when the pachinko ball 100 is launched, the state determination unit 95 is in a normal state when detection signals are output in the order of the detection sensor 105 and the detection sensor 106 between the drive signals of the rotary solenoid 51. Judge that there is. On the other hand, when the detection signal output between the drive signals of the rotary solenoid 51 is only the detection sensor 105, or after the detection signal is output from the detection sensor 105 or the detection sensor 106, the detection sensor 106 or the detection sensor again. When a detection signal is output from 105, the state determination unit 95 determines that the state is abnormal.

  In the present embodiment, when the collection port 65 is opened, all the pachinko balls 100 located inside the loading portion 54 or the launch passage 90 are collected. However, the present invention is not limited to this. For example, as shown in FIG. 10, it is possible to hold a state in which one pachinko ball 100 is loaded in the loading unit 54 and to provide a collection port 107 at a position where other pachinko balls 100 can be collected. . In this case, when the recovery port 107 is opened, the firing control device 92 needs to stop the power supply to the rotary solenoid 51 of the firing device 45 even if the operation handle is operated. In this case, one pachinko ball 100 is loaded in the loading unit 54 of the launching device 45 without driving the ball feeding device 85. However, it may not be driven first. In addition, since the state where the pachinko ball 100 is loaded in the loading unit 54 can be secured, it is possible to prevent idle shooting by the launching device when the game is resumed and to smoothly resume the game.

  In the present embodiment, the recovery port is shielded after a predetermined time has elapsed after the recovery port is opened. However, the present invention is not limited to this. For example, as shown in FIG. A recovery detection sensor 110 that detects the pachinko sphere 100 immediately after being recovered by the sensor 46 is provided on the upstream side of the recovery passageway 46, and the recovery port is recovered after a predetermined time from when the recovery detection sensor 110 no longer detects the pachinko sphere 100. It is also possible to shield 107.
