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.

  A pachinko machine installed in a game hall such as a pachinko store has a game area where a game ball flows down on the game board, and when a handle provided on the pachinko machine is turned (launched), In general, a game ball is launched toward a game area with a launch strength based on the rotation amount (adjustment amount) of the handle. Such a pachinko machine is provided with a launching device that launches game balls one by one at regular intervals, and a ball feeding device that supplies game balls to the launching device one by one. The launching device is provided with a hammer-like knock arm that is driven by a rotary solenoid or the like to move (oscillate or move linearly), and the knocking arm is moved at a launch speed based on the amount of rotation of the handle to play a game ball By hitting, a game ball is launched with a launch strength based on the amount of rotation of the handle. The game ball launched by the launcher reaches the game area by a guide passage provided above the launcher. The player adjusts the launch strength by adjusting the amount of rotation of the handle so that the launched game ball enters the winning opening in the game area.

  When the turning amount of the handle is small and the knocking speed of the knock arm is slow, the game ball that has been launched may not reach the game area due to weak momentum and may return the guide path. The game balls that return the guide passage in this way are called foul balls or return balls, and many of them are collected from a collection port provided in the middle of the guide passage.

Depending on the aging of the device that drives the knock arm, the amount of rotation of the handle may not correspond to the knock arm launch speed. In such a case, it is necessary to adjust the knock arm launch speed. In addition, the foul balls may interfere with normal games such as a newly-launched game ball in the guide passage, so it is important to detect the foul balls and manage their number. And desirable for players. Japanese Patent Application Laid-Open No. H10-133867 and Japanese Patent Application Laid-Open No. 2004-228688 detect actual launch strength using a strain gauge provided on a member that launches game balls, adjust the driving force based on the detected launch strength, and detect the number of foul balls. It is proposed in Patent Document 2 and the like.

  However, in the pachinko machine as described above, the foul ball may return to the launching device without being recovered from the recovery port. In this case, since the launching device launches game balls at regular intervals, an abnormal state occurs in which the knock arm strikes the game ball newly supplied by the ball feeding device and the foul ball returned at the same time. In such an abnormal state, the momentum of the game ball to be launched does not become the momentum intended by the player who rotates the handle, so that the player's interest is impaired, and the knock arm is loaded. This may cause a failure of the launcher. In order to eliminate such an abnormal state where the foul ball has returned to the launching device, it must be struck hard so that the foul ball does not return to the launching device. To that end, the amount of rotation of the handle must be increased. I had to. During the game, the player adjusts the amount of rotation of the handle so that the launched game ball enters the winning opening in the game area, and removes the adjusted amount of rotation to increase the amount of rotation of the handle. It has been a burden on the player to adjust the amount of rotation after the abnormal state is resolved.

  The present invention has been made in view of the above problems, and a ball game in which an abnormal state in which a foul ball is returned to the launching device can be quickly resolved without putting a burden on the player and can be returned to a normal state. The purpose is to provide a machine.

  In the ball game machine of the present invention, the game balls supplied from the ball feeder are launched one by one by a knock arm that moves at a launch speed based on the adjustment amount of the launch operation, and the launched game balls pass through the guide passage. In a ball game machine that passes through to a game area, ball detecting means for detecting game balls passing through the guide passage one by one, launching operation of the knock arm and detection of game balls by the ball detecting means alternately A state determination unit that determines whether or not the normal state is performed; an abnormal state stop unit that stops supply of a game ball by the ball feeding device when the state determination unit determines an abnormal state; and the state When the determination means determines an abnormal state, the abnormal state adjusting means for adjusting the knock arm launch speed to a preset special speed regardless of the adjustment amount of the firing operation, and under the abnormal state When the ball detecting means does not detect a game ball even if the knock arm performs a launching operation, the supply stop of the game ball by the abnormal time stopping means and the adjustment of the launch speed by the abnormal time adjusting means are canceled. An abnormality release unit is provided. The special speed is preferably as fast as possible in order to quickly resolve the abnormal state where the foul ball returns to the launching device. However, for example, a speed at which two consecutive game balls can reach the game area. If it can be set regardless of the adjustment amount of the launch operation, it may be set as appropriate.

  In addition, when the state determination means determines an abnormal state, when the knock arm launch speed based on the adjustment amount of the firing operation is equal to or higher than a preset reference speed, the launch speed of the abnormal condition adjustment means It is preferable to provide an abnormality adjustment prohibiting means for prohibiting the adjustment. In addition, what is necessary is just to set the speed | rate etc. which can be made to reach | attain the collection | recovery port for collect | recovering a foul ball | bowl both, for example, as a reference | standard speed | rate. When the special speed is set within the range of the swing speed that can be adjusted based on the adjustment amount of the launch operation, the reference speed may be made equal to the special speed.

  Further, it is preferable that the special speed is set faster than a maximum launch speed that can be adjusted based on an adjustment amount of the firing operation.

  In addition, operation detecting means for detecting that the firing operation is performed and outputting an operation detection signal, and prohibiting the operation of the knock arm when the operation detection signal is not output in a normal state, It is preferable to include an operation control means for operating the knock arm even when the operation detection signal is not output in an abnormal state.

  In addition, it is preferable to provide notifying means for notifying that the launch speed is adjusted to the special speed by the abnormal time adjusting means.

  According to the ball game machine of the present invention, it is determined whether or not the knock arm launching operation and the ball detection means detect the game balls passing through the guide passage one by one in a normal state. When the state determining unit makes a determination and the state determining unit determines an abnormal state, the abnormal time stopping unit stops the ball feeding device, and the abnormal time adjusting unit knocks regardless of the adjustment amount of the launch operation. Since the launching speed of the arm is adjusted to a special speed set in advance, the game ball is not newly supplied by the ball feeding device, and the foul ball is launched strongly so that it does not return to the launching device. When the ball detecting means does not detect the game ball even if the knock arm performs the launch operation under the abnormal state, the abnormal state returning to can be quickly resolved without placing a burden on the player. Abnormal Dividing means, stopping the ball feeding apparatus according abnormality stop means, and, since releasing the regulation, the launch speed of the knock arm by abnormal time adjustment means can be returned to the normal state.

  In addition, when the state determination unit determines an abnormal state, when the knock arm launching speed based on the adjustment amount of the firing operation is equal to or higher than a preset reference speed, the adjustment of the launching speed by the abnormality adjusting unit is prohibited. When there is an abnormal adjustment prohibition means, that is, when the launch speed that can eliminate the abnormal state is within a range that can be adjusted based on the adjustment amount of the launch operation, this launch speed is taken as the reference speed, When the launch speed based on the adjustment amount of the operation is higher than the reference speed, the launch strength of the launching device is not adjusted by the abnormal-time adjusting means, so that the momentum of the game ball to be launched and the player's launch operation By suppressing the difference from the intended momentum, it is possible to reduce the player from feeling uncomfortable.

  Further, the special speed is set faster than the maximum launch speed that can be adjusted based on the adjustment amount of the launch operation, that is, faster than the knock arm launch speed that can be used in the game, The abnormal state where the foul ball is returned to the launching device can be quickly resolved.

  In addition, an operation detection means for detecting that a firing operation is being performed and outputting an operation detection signal; and in a normal state, when the operation detection signal is not output, the operation of the knock arm is prohibited, and in an abnormal state Is provided with an operation control means for operating the knock arm even when the operation detection signal is not output, so that in a normal state, an illegal act of playing a game without performing a launch operation is prevented, and in an abnormal state, Even when the firing operation is not performed, since the launching device is operated with the launch strength by the abnormality adjusting means, the abnormal state in which the foul ball returns to the launching device can be quickly resolved.

  Further, by providing a notification means for notifying that the launch speed is adjusted to the special speed by the abnormal time adjustment means, the momentum of the game ball to be launched differs from the momentum intended by the player performing the launch operation. It is possible to make the player recognize and prevent the player from feeling uncomfortable.

Further, on both sides of the outlet 33a of the launcher side guide passage 33, there are provided recovery ports 41 and 42 that open upward, and the game balls that have fallen into the recovery ports 41 and 42 are recovered.

  The launcher 25 is exposed on the lower front side of the main body member 11. When the operation unit 22 described above is rotated, the launching device 25 launches a game ball upward with a launch strength corresponding to the rotation amount of the operation unit 22.

  As shown in FIGS. 3 and 4, the firing device 25 includes a knock arm 50, a rotary solenoid 51, a first stopper 52, a second stopper 53, a loading portion 54, and a base plate 55. Each of the rotary solenoid 51, the first stopper 52, the second stopper 53, and the loading portion 54 is fixed to the base plate 55 with screws or the like.

  The knock arm 50 includes a long piece 50a having a substantially square shape when viewed from the front, and a short piece 50b having a predetermined angle with respect to the long piece 50a. One end of the long piece 50a and the short piece 50b Are connected in a V shape. The drive shaft 51a of the rotary solenoid 51 is fixed to the insertion hole provided in the connecting portion between the long piece 50a and the short piece 50b. When power is supplied to the rotary solenoid 51, the knock arm 50 is rotated upward (clockwise indicated by arrow A in the figure). When power supply to the rotary solenoid 51 is stopped, the knock arm 50 is moved by its own weight. It rotates downward (counterclockwise indicated by arrow B in the figure). A substantially cylindrical hitting rod 50c is provided at the tip of the long piece 50a to hit the game ball loaded in the loading portion 54 when the knock arm 50 momentarily rotates upward. Thus, the knock arm 50 rotates at the launch speed corresponding to the driving force of the rotary solenoid 51, and the launch strength when the game ball is launched is in accordance with the launch speed of the knock arm 50.

  The first stopper 52 and the second stopper 53 are provided to stop the rotation of the knock arm 50 so that the clockwise or counterclockwise rotation of the knock arm 50 falls within a predetermined range. The knock arm 50 rotated clockwise by the rotary solenoid 51 is stopped by the short piece 50b coming into contact with the first stopper 52 immediately after the hitting ball 50c hits the game ball loaded in the loading portion 54. The knock arm 50 rotated counterclockwise by its own weight from the position stopped by the first stopper 52 is stopped by the long piece 50 a coming into contact with the second stopper 53. That is, the knock arm 50 swings between the first stopper 52 and the second stopper 53.

  The loading unit 54 includes a first component member 60 and a second component member 61 assembled to the base member 55. A part of the distance between the first component member 60 and the second component member 61 is wider than the diameter of the hitting rod 50c and narrower than the diameter of the game ball. Further, the space formed between the first component member 60 and the second component member 61 is located on the rotation trajectory (indicated by a dashed line arrow in FIG. 4) of the striking rod 50c. The game ball sent from the ball feeding device 26 is set (loaded) on the rotation trajectory of the striking rod 50c in a holding state narrowly inserted in the interval between the first component member 60 and the second component member 61. .

  The ball feeding device 26 feeds the gaming balls arranged in a line on the inclined surface of the ball feeding passage 27 one by one into the loading portion 54 of the launching device 25. The ball feeding device 26 includes an introduction port 86 connected to the end outlet of the ball feeding passage 27 and a delivery port 87 for sending out game balls toward the loading portion 54, and sends the game balls received from the introduction port 86. One ball is sent out from the outlet 87. Note that the ball feeding device 26 is assembled on the back side of the lower door 13 so that when the lower door 13 is closed, the delivery port 87 and the loading portion 54 face each other.

  Between the loading portion 54 of the launching device 25 and the groove-like game board side guide passage 32, a groove-like launching device side guide for guiding the game ball launched from the loading portion 54 to the game board side guide passage 32. A passage 33 is provided. In the launcher side guide passage 33, a ball detection sensor (ball detection means) 91 for detecting the passing game balls one by one and outputting a ball detection signal is arranged. As long as this ball detection sensor 91 can detect game balls one by one, for example, a reflective photosensor or the like may be used.

  Driving control of the launching device 25 and the ball feeding device 26 is performed by the launching control device 92. The firing control device 92 includes an operation control unit (operation control unit) 93, a state determination unit (state determination unit) 94, an abnormal time stop unit (abnormal time stop unit) 95, and an abnormal time adjustment unit (abnormal time adjustment unit) 96. , An abnormal time release unit (abnormal time release unit) 97 and an abnormal time adjustment prohibition unit (abnormal time adjustment prohibition unit) 98 are provided.

  The operation control unit 93 performs power control of the rotary solenoid 51 so that the knock arm 50 rotates at a launch speed based on the resistance value of the rotation amount measurement volume 23. In a normal state, which will be described later, the operation control unit 93 supplies power to the rotary solenoid 51 when no operation detection signal is output from the touch sensor 24 that detects that a human hand is in contact with the operation unit 22. Even if the operation detection signal is not output in an abnormal state, power is supplied to the rotary solenoid 51. Further, the operation control unit 93 controls the power of the ball feeding device 26 so as to be interlocked with the operation of the rotary solenoid 51, and each time a game ball is launched from the launch device 25, a new game ball is launched one by one. 25. The power control of the rotary solenoid 51 and the ball feeding device 26 in the abnormal state is performed according to the abnormal time stop unit 95, the abnormal time adjustment unit 96, and the abnormal time adjustment prohibition unit 98.

  The state determination unit 94 monitors the power supply performed to the rotary solenoid 51 at regular intervals (for example, so as to be launched 100 times per minute) and the output of the ball detection signal from the ball detection sensor 91 after the power supply. When the power feeding and the output of the ball detection signal are performed alternately, it is determined that the game ball launched from the launching device 25 is in a normal state reaching the game area 16, and the power feeding and the ball detection are performed. When the output of the signal is not performed alternately, it is determined as an abnormal state in which the game ball launched from the launching device 25 has not reached the game area 16. As an abnormal state, for example, after the power supply to the rotary solenoid 51 is performed and the ball detection signal is output a plurality of times until the next power supply, the foul ball has returned to the launching device 25, There is a state in which a plurality of game balls are launched from the launching device 25 at the same time.

  When the state determination unit 94 determines an abnormal state, the abnormal time stop unit 95 stops the supply of the game ball in the power control of the ball transport device 26 by the operation control unit 93.

  When the state determination unit 94 determines an abnormal state, the knock arm 50 rotates the power control of the rotary solenoid 51 by the operation control unit 93 at a preset special speed regardless of the resistance value of the rotation amount measurement volume 23. Adjust to move. The special speed is, for example, faster than the maximum value of the launch speed that can be adjusted based on the resistance value of the rotation amount measurement volume 23 in the electric power control of the rotary solenoid 51 by the operation control unit 93, that is, the loading unit 54 has a plurality of special speeds. Even if there are game balls, the game balls are set to a speed at which the game balls 16 can reliably reach the game area 16 and the collection ports 41 and 42 for collecting the foul balls. In this way, the abnormal state in which the foul ball is returned to the launching device can be quickly resolved by rotating the operation unit 22 in the game to make the special speed faster than the maximum launch speed that can be adjusted. Can do.

  The abnormal state canceling unit 97 is in an abnormal state where the power supply to the rotary solenoid 51 and the output of the ball detection signal from the ball detection sensor 91 are not alternately performed, and the ball is supplied even if the power supply to the rotary solenoid 51 is performed. When the detection signal is not output, that is, when it can be estimated that the game unit is not loaded in the loading unit 54, the supply of the game ball of the ball feeding device 26 by the abnormal stop unit 95 is stopped and the abnormal adjustment is performed. The adjustment of the knocking speed of the knock arm 50 by the part 96 is released.

  The abnormal adjustment prohibition unit 98 is activated when the knocking speed of the knock arm 50 based on the resistance value of the rotation amount measurement volume 23 is equal to or higher than a preset reference speed when the state determination unit 94 determines an abnormal state. In the power control of the rotary solenoid 51 by the control unit 93, the adjustment by the abnormal time adjustment unit 96 with the launch speed as a special speed is prohibited, and the launch speed is based on the resistance value of the rotation amount measurement volume 23 as in the normal state. To. The reference speed is set to a speed at which, for example, two consecutive game balls can reach either one of the collection ports 41 and 42 for collecting the foul balls. As described above, even if the knocking speed of the knock arm 50 is not set to the special speed, the abnormal state can be solved by rotating the knock arm 50 at the driving speed based on the rotation amount of the operation unit 22. By preventing the adjustment by the time adjustment unit 96, it is possible to suppress the difference between the momentum of the game ball to be launched and the momentum intended by the player who performs the launch operation, and to reduce the player from feeling uncomfortable. be able to.

  The lamp lighting control unit (notification unit) 100 monitors the power control of the rotary solenoid 51 by the operation control unit 93, and when the launching speed of the knock arm 50 is adjusted to the special speed by the abnormality adjusting unit 96, By turning on the lamp 101 in a predetermined manner, it is notified that the special speed has been adjusted. The lamp 101 may be provided at an appropriate position such as the front surface of the upper door 12 or the front surface of the game board 30 as long as the player can visually recognize the lamp 101.

  Next, the flow of processing when launching a game ball in the pachinko machine 10 will be described based on the flowchart of FIG.

  When the operation unit 22 is rotated, the operation control unit 93 performs power control of the rotary solenoid 51 so that the knock arm 50 rotates at a launch speed based on the resistance value of the rotation amount measurement volume 23. At this time, when the operation detection signal is not output from the touch sensor 24, power is not supplied to the rotary solenoid 51. Further, the operation control unit 93 controls the power of the ball feeding device 26 so as to be interlocked with the operation of the rotary solenoid 51, and each time a game ball is launched from the launch device 25, a new game ball is launched one by one. 25.

  The state determination unit 94 monitors the power supply to the rotary solenoid 51 and the output of the ball detection signal from the ball detection sensor 91. If the power supply and the output of the ball detection signal are alternately performed, the state determination unit 94 When it is determined that the game ball launched from the device 25 is in a normal state where it has reached the game area 16 and power feeding and output of the ball detection signal are not performed alternately, the game ball is launched from the launching device 25. It is determined that the gaming ball has not reached the gaming area 16 as an abnormal state.

  When the state determination unit 94 determines an abnormal state, the abnormality stop unit 95 stops the supply of the game ball in the power control of the ball transport device 26 by the operation control unit 93.

  When the state determination unit 94 determines an abnormal state and the launching speed of the knock arm 50 based on the resistance value of the rotation amount measurement volume 23 is equal to or higher than a preset reference speed, the abnormality adjustment prohibition unit 98 adjusts the abnormality. Although the adjustment of the launching speed by the unit 96 is prohibited, when the launching speed of the knock arm 50 based on the resistance value of the rotation amount measuring volume 23 has not reached the reference speed, the operation control unit 93 causes the abnormality adjusting unit 96 to Regardless of the resistance value of the rotation amount measurement volume 23, the power control of the rotary solenoid 51 is adjusted so that the knock arm 50 rotates at a preset special speed.

  In an abnormal state in which the power supply to the rotary solenoid 51 and the output of the ball detection signal from the ball detection sensor 91 are not alternately performed, a foul ball is launched into the game area 16 or any of the collection ports 41 and 42 When the ball detection signal is not output even when power is supplied to the rotary solenoid 51 and the ball detection signal is not output, the abnormal time release unit 97 stops the supply of the game ball of the ball feeding device 26 by the abnormal time stop unit 95, The adjustment of the knocking speed of the knock arm 50 by the abnormality adjusting unit 96 is released.

  When the operation unit 22 is not rotated and the rotation amount is lost, the operation control unit 93 stops the power control of the rotary solenoid 51 and the ball feeding device 26. In this way, the abnormal state in which the foul ball is returned to the launching device 25 can be quickly resolved without placing a burden on the player, and the normal state can be restored.

  In the above embodiment, the knock arm 50 swings when driven by the rotary solenoid 51. However, the form of the knock arm is not limited to this. For example, the knock arm 50 drives directly by the linear solenoid. As long as a game ball can be launched, an appropriate form may be used.

  In the above embodiment, the lamp lighting control unit 100 controls the lighting of the lamp 101 to notify that the knocking speed of the knock arm 50 is adjusted to the special speed by the abnormal time adjusting unit 96. For example, an appropriate mode is used such as providing a sound control device and outputting a sound from a speaker, or providing a liquid crystal panel that displays a change and stop of a symbol, and displays an image for notification.
