Description

  The present invention relates to a winning device for a ball game machine having a pair of opening and closing members.

  Pachinko machines are known as bullet ball machines installed in amusement halls such as pachinko parlors. A winning device called a starting chucker (or an electric tulip) is provided on the game board surface of the pachinko machine, and a winning lottery is performed in response to the winning of a game ball in the starting chucker. For this reason, it is of great concern for the player to make the starting chucker win many game balls.

  The starter chucker has a pair of opening and closing blades, and the pair of opening and closing blades are substantially reverse-shaped so that the game balls can be easily won, and the game balls are difficult to win by standing in parallel with each other. The closed state becomes. The pair of opening / closing blades is driven by a blade driving unit including a solenoid and a transmission mechanism that transmits the driving force of the solenoid to the opening / closing blades.

  By the way, conventionally, a piano wire is put on the surface of the game board from the gap of the glass door that covers the front of the game board, and this piano wire is hooked on the opening and closing blades to forcibly open the opening and closing blades. There is a known dishonest act of winning the starting chucker, the so-called piano wire goto.

Patent Document 1 discloses a technique for dealing with illegal acts such as piano wire goto. The winning device described in Patent Document 1 is provided with a restraining piece and a notch in the transmission mechanism of the blade drive unit, and when the opening / closing blade is driven in the open state, the restraining piece fits into the notch and the opening / closing blade is driven in the closed state. Then, the holding piece is configured to come out of the cutout portion. For example, even if the opening / closing blade is forcibly opened using a piano wire, the holding piece stops the opening / closing blade.
JP 2001-314579 A

  However, in the technique described in Patent Document 1, since the restraining piece is incorporated in the transmission mechanism of the blade driving unit, the restraining piece becomes a small member, for example, when a strong force is applied to the opening and closing blades due to the piano wire being pulled strongly. However, there was a problem that the holding piece was broken and the opening and closing blades were opened, and a lot of game balls were illegally awarded to the starting chucker.

  An object of the present invention is to provide a winning device that can reliably prevent a gaming ball from being illegally won by an illegal act such as piano wire goto.

  A winning device for a ball game machine according to the present invention includes a winning opening provided in a game board, an obstacle member provided above the winning opening, and a left and right formed between the winning opening and the obstacle member. A pair of opening and closing members that take an open state in which a game ball easily enters from the winning path and a closed state in which a game ball does not easily enter from the left and right winning paths, and an opening and closing member that drives the opening and closing member to the open state or the closed state A driving means, a pair of shutters that are displaced between an entry position that enters the winning path so as to block the left and right winning paths, and a retreat position that retracts from the left and right winning paths, and the open / close member is in the open state. And shutter driving means for driving the shutter to the retracted position when driven, and driving the shutter to the entering position when the opening / closing member is driven to the closed state. Examples of the obstacle member include a nail and a component member forming a winning opening different from the winning opening.

  Preferably, the shutter driving means drives the shutter to the entry position after the opening / closing member is driven to the closed state. Thereby, it can prevent that a shutter bites a ball.

  The opening / closing member is provided with a locking claw, and the shutter has an engaged portion that engages the locking claw when the opening / closing member is in the open state to lock the shutter in the entry position. Preferably, the shutter driving means drives the shutter to the retracted position before the opening / closing member is driven to the open state. Thereby, for example, even when the opening / closing member is opened illegally, the shutter blocks the winning path, and since the shutter is locked, the shutter cannot be illegally retracted.

  According to the winning device of the ball game machine of the present invention, when the pair of opening and closing members are driven to the closed state, the pair of shutters are driven to the entry positions that respectively block the left and right winning paths to the winning opening. Even when the opening / closing member is opened using the piano wire, since the shutter blocks the winning path, it is possible to reliably prevent the gaming ball from being won illegally.

  As shown in FIG. 1, a pachinko machine (ball game machine) 10 has a game board 12 disposed inside a main body frame 11, and a front door 13 is assembled to the front surface of the main body frame 11 so as to be freely opened and closed. ing. Below the front door 13, there are provided a tray 14 that houses a pachinko ball (game ball) 9 and an operation handle 15 that is operated when the pachinko ball 9 is launched into the game area 12 a of the game board 12. An opening 13 a is formed in the center of the front door 13, and the game area 12 a can be visually recognized through a glass plate provided in the front door 13.

  An LCD 16 on which three symbols and numbers are variably displayed in accordance with the game content is provided at the upper center of the game area 12a. A through chucker 17 is provided on the side of the LCD 16. In addition, below the LCD 16, the two nails 18, the first starting chucker (obstacle member) 21, the second starting chucker (winning device) 22, the attacker 23, and the game area 12 a flow down without winning. An out port 24 for collecting the out balls is provided.

  As shown in FIGS. 2 and 3, the first start chucker 21 has a base 30 whose upper surface is open and a first start winning opening 31 provided in the base 30. The pachinko ball 9 that has passed between the two nails 18 wins the first start winning opening 31. The distance between the nails 18 is about the size of one pachinko ball 9. A first winning ball detection sensor (not shown) is provided in the first start winning port 31, and the first winning ball detection sensor inputs a winning signal to the control unit 32 when detecting a winning ball.

  The second starter chucker 22 includes a base 33 whose upper surface is opened, a second start winning port (winning port) 34 provided on the base 33, and rotating shafts 39 provided on both left and right ends of the base 33. A pair of attached opening / closing blades (opening / closing member) 35, a blade driving unit (opening / closing member driving means) 36 for swinging the opening / closing blade 35 around the rotation shaft 39, and a pair provided on the left and right of the first starting chucker 21. And a shutter drive unit (shutter drive means) 38 that slides the shutter 37 up and down.

  The pair of opening / closing blades 35 are substantially inverted and have an open state in which the left and right winning paths 40 formed between the first starter chucker 21 and the open state are opened in parallel with each other, and the winning paths 40 are closed. Swings between the closed state. The blade driving unit 36 includes, for example, a solenoid and a transmission mechanism that transmits a driving force of the solenoid to the pair of opening and closing blades 35 to swing. The blade drive unit 36 is controlled by a control unit 32 that comprehensively controls each unit of the pachinko machine 10, and based on an instruction signal (open instruction signal or close instruction signal) from the control unit 32, a pair of opening and closing blades 35 is driven.

  The pair of shutters 37 are disposed along the left and right side surfaces of the base 30 of the first starter chucker 21 and are slidable up and down along these left and right side surfaces. The shutter 37 moves between a retreat position that retreats upward from the winning path 40 and an entering position that enters the winning path 40 so as to close the winning path 40. The shutter drive unit 38 drives the pair of shutters 37 based on an instruction signal (an entry instruction signal or an evacuation instruction signal) from the control unit 32.

  In response to the winning of the pachinko ball 9 to the through chucker 17, the control unit 32 performs an open lottery to determine whether or not to open the second starter chucker 22, and when the open lottery is won, Is controlled to be in an open state for a preset opening time.

  The control unit 32 inputs a retract instruction signal to the shutter drive unit 38 when inputting an opening instruction signal to the blade drive unit 36, and enters an instruction to enter the shutter drive unit 38 when inputting a close instruction signal to the blade drive unit 36. Input the signal.

  However, in order to drive the shutter 37 to the retracted position before the opening / closing blade 35 is driven to the open state, the control unit 32 inputs a retract instruction signal to the shutter drive unit 38 for a predetermined time (this predetermined time is The opening instruction signal is input to the blade driving unit 36 with a shift (set in consideration of the time required from when the retracting instruction signal is issued until the shutter 37 is driven to the retracted position). Thereby, when it is driven normally, the lock claw 41 described later is not caught in the lock hole (engaged portion) 42.

  In addition, the control unit 32, after the opening and closing blades 35 are driven to the closed state, to drive the shutter 37 to the approach position, a predetermined time after inputting the closing instruction signal to the blade driving unit 36 (this fixed time is It is set in consideration of the time required from when the opening instruction signal is issued until the opening / closing blade 35 is driven to the closed state), and the approach instruction signal is input to the shutter drive unit 38. Thereby, it can prevent that the shutter 37 bites a ball | bowl.

  A lock claw 41 formed in a crescent shape is provided at the base end portion of the opening / closing blade 35. In addition, a lock hole 42 is formed in the lower portion of the shutter 37. When the shutter 37 is in the entry position, the tip of the lock claw 41 is configured to be inserted into the lock hole 42 when the opening / closing blade 35 changes from the open state to the closed state.

  Hereinafter, the opening / closing operation of the second starter chucker 22 will be described along the flow of the flowchart of FIG. 4. When the pachinko ball 9 wins the through chucker 17, the open lottery is performed, and when the open lottery is won, the first start chucker 22 is opened and closed.

  The control unit 32 inputs a retraction instruction signal to the shutter drive unit 38, and inputs an opening instruction signal to the blade drive unit 36 with a predetermined time shift from this input. After the shutter drive unit 38 drives the shutter 37 to the retracted position, the blade drive unit 36 drives the open / close blade 35 to the open state. The shutter 37 moves without being locked by the lock claw 41. Since the winning path 40 is opened, the pachinko ball 9 can easily win the second start winning opening 34.

  When a predetermined opening time elapses, the control unit 32 inputs a closing instruction signal to the blade driving unit 36 and inputs an approaching instruction signal to the shutter driving unit 38 with a predetermined time shift from this input. After the blade driving unit 36 drives the opening / closing blade 35 to the closed state, the shutter driving unit 38 drives the shutter 37 to the entry position. The shutter 37 is driven to the entry position without biting the ball. When the pachinko ball 9 passes through the through chucker 17 and wins the open lottery, the above opening / closing operation is repeated.

  When the open / close blade 35 of the second starter chucker 22 is driven to the closed state, for example, when a piano wire goto action is attempted and the piano wire is hooked and pulled by one open / close blade 35, FIG. As shown, the open / close blades 35 are forcibly opened. However, since the winning path 40 is blocked by the shutter 37, the pachinko ball 9 is not illegally won in the second start winning opening 34.

  In addition, even when an unauthorized action is attempted in which the shutter 37 is forcibly moved to the retracted position after the opening and closing blades 35 are forcibly opened, the lock pawl 41 is locked. Since the shutter 37 is locked at the entry position by entering 42, the shutter 37 cannot be moved to the retracted position. Thereby, a goto action can be prevented more reliably.

  In the above embodiment, the first starter chucker 21 is used as the obstacle member, but other members such as a nail may be used.

  In the above embodiment, the winning path 40 is completely closed when the opening / closing blade 35 is in the closed state, but the winning path 40 may be closed with a gap of about nine pachinko balls.
