Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a winning ball device for a pachinko machine, and more specifically, a starting ball socket for activating the winning ball device, which is used in the winning ball device. This invention relates to a winning ball device that opens and closes in response to the opening and closing operations of a door plate.

[Conventional technology]

Pachinko machines are equipped with various winning ball devices,
It is designed to make the game more interesting.
A winning ball device called an Atatsuka starts a slot machine built into a gaming machine when a ball enters a specific winning hole or when a ball enters a specific winning hole. For example, the combination of symbols “7-7-
7'', the door plate that opens and closes the winning ball receptacle is opened. This door plate opens to project forward from the board surface of the game machine, so balls falling on the board surface are easily caught by this door plate and guided to the winning ball receptacle of the winning ball device. This makes it extremely easy to win prizes.

In such a winning ball device, in order to further enhance the interest of the game, after a ball hits a specific safe hole, the ball is placed in a starting ball socket (hereinafter referred to as a starting ball) attached to the winning ball device. It is known that the opening operation of the opening/closing door plate is started only when the user enters the door. The door plate opened in this way is automatically closed when a certain number of balls enter the winning ball socket of the winning ball device via the door plate, or when a certain predetermined period of time has elapsed. It's getting old.

Furthermore, when one ball enters the particular safe hole, the door plate is scheduled to be opened eight times, for example, on the condition that the starting ball enters the starting ball socket. In other words, after winning a prize in a specific safe hole, each time a winning ball occurs in the starting ball socket,
The door plate will be opened and this will be repeated eight times.

However, if a winning ball is won in a specific safe hole, and one winning ball is placed in the starting ball socket and the door plate is open, if a ball continues to enter the starting ball socket, this The ball is not actually used to open or close the door plate, but is counted as one starter ball. Therefore, the number of opening and closing times of the door plate is reduced by one from the number of openings and closings that are actually allowed. In extreme cases, a number of starter balls may enter the starter ball receptacles during the initial opening of the door plate, resulting in the door plate opening and closing only once.

In order to solve this problem, the number of balls that hit the starting ball socket when the door plate is open is counted and memorized, and the number of balls that hit the starting ball socket is counted and stored in the door plate. A so-called credit system winning ball device is used in which the ball can be released repeatedly.

[Problem that the invention attempts to solve]

By the way, when a credit system is adopted for the above-mentioned winning ball device, it is necessary to memorize the number of effective starting balls to open the door plate, and also to store the number of starting balls that are effective for opening the door plate. A circuit device is required to subtract the number of starting balls one by one. Furthermore, it is necessary to display the remaining number of starting balls that have been credited, and the display mechanism becomes complicated, which inevitably increases the cost of the pachinko machine.

This invention was made to solve the problems of conventional pachinko machines as described above, and the starting ball does not enter the starting ball socket while the door plate of the winning ball device is open. An object of the present invention is to provide a winning ball device for a pachinko machine.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is designed to open and close a starting ball socket that receives the starting ball that causes the door plate to open, on the openable/closable door plate of the winning ball device. An opening/closing plate is provided, and the starting ball socket is closed when the door plate is open, and the starting ball socket is opened only when the door plate is closed.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

〔Example〕

In FIG. 1 showing an outline of the winning ball device of the present invention, a mounting plate 2 in which a horizontally elongated winning ball opening 1, which serves as an entrance for winning balls, is formed with a base 3 of the gaming machine (see FIGS. 2 and 3). Base 3 so that it is almost on the same surface
Fixed. The mounting plate 2 has a winning ball opening 1.
Box-shaped starting ball receiving chambers 5, 5 are attached to both sides of the starting ball so as to form a starting ball opening 4 that serves as a socket for the starting ball. The mounting plate 2 further includes:
Above this starting ball receiving chamber 5, the winning ball opening 1
Opening windows 7, 7 are formed with vertically long slits 6, 6 in between.

A winning ball receiving chamber 8 is formed on the back side of the mounting plate 2 so as to surround the winning ball opening 1. The back side of the receiving chamber 8 is covered with a back plate 10 formed from an outlet 9 for winning balls. As is clear from the figure, the bottom surface of the winning ball receiving chamber 8 is an inclined surface toward the center so that the winning balls flowing therein can flow to the discharge port 9 without being accumulated. Behind the outlet 9,
A winning ball detector 30 is provided. This detector 30 includes a detection lever 31 that is swung by the winning balls discharged from the ejection port 9, and this swing lever 3.
It is composed of a micro switch 32 that detects the vibration of the 1 as an electric signal.

On the other hand, a door plate 20 is rotatably supported on the mounting plate 2 by shafts 21, 21 so as to open and close the prize ball opening 1. Fan-shaped side plates 22, 22 are formed on both sides of the front surface of this door plate 20, and an opening/closing plate 24 consisting of two side opening/closing plate parts 23a, 23b integrated so that the cross section forms a V-shape is formed on both upper sides. are integrally formed. This opening/closing plate 24
The angle formed by the opening/closing plate portions 23a and 23b is a complementary angle to the swing angle of the door plate 20. The door plate 20 is
The relationship between the side plate 22 and the pivot position provides rotational sliding properties in the opening direction.

An engagement lever 25 extending rearward is integrally formed on one side edge of the door plate 20. This engagement lever 25 passes through a slit 10a formed in the back plate 10 and projects behind the back plate 10,
It is configured to be interlocked with the control mechanism 19.
This control mechanism 19 is rotated by a reversible motor 14 while slidingly contacting an opening/closing lever 13 pivoted on a support plate 12 attached to an attachment mount part 11 and an upper edge of this opening/closing lever 13. It is constituted by a control arm 15.
A well-known slip mechanism 16 is interposed between the control arm 15 and the drive shaft 14a of the motor 14.

As shown in FIG. 2, when the control arm 15 is in the position shown by the solid line, that is, in the closed position,
Since the opening/closing lever 13 is prevented from rotating upward (clockwise), the door plate 20
3, the side plate 22 is prevented from rotating counterclockwise due to the action of gravity, that is, from rotating in the opening direction. From this state, when the motor 14 rotates counterclockwise (forward rotation) and the control arm 15 moves to the position shown by the two-dot chain line, the opening/closing lever 13 becomes able to rotate upward. As a result, the door plate 20 is rotated clockwise by the gravitational action of the side plate 22 and opened. When the motor 14 reverses, the control arm 15 moves to the closed position shown by the solid line, so the open door plate 20 is returned to the closed position by the interlocking action of the opening/closing lever 13 and the engagement lever 24. . The motor 14 is designed to be driven in either direction for a certain period of time, and when the control arm 15 comes into contact with the support plate 12 and when the stopper 13a formed protruding from the upper edge of the opening/closing lever 13 When abutting, the rotation of the motor 14 is absorbed by the slip mechanism 16.

As shown in FIGS. 3A and 3B, when the door plate 20 is held in the closed position (FIG. 3A) by the control mechanism 19, the door plate 20 closes the winning ball opening 1. At the same time, one opening/closing plate portion 23a of the opening/closing plate 24 closes the opening window 7. The other opening/closing plate portion 23b of the opening/closing plate 24 enters into the space between the mounting plate 2 and the back plate 10. On the other hand, when the door plate 20 is moved to the open position (FIG. 3B) by the control mechanism 19, the door plate 20 opens the winning ball opening 1, and the rear opening/closing plate part 23B of the opening/closing plate 24 starts. The starting ball opening 4 of the ball receiving chamber 5 is then closed.

The opening/closing control of the opening/closing door plate 20 described above is performed by the motor drive control circuit shown in FIG. 4.

When a ball hits a specific safe hole in the initial state where the door plate 20 of the winning ball device is closed, a winning pulse signal WP is output from the winning detection section 40. The down counter 42 is set to the initial value "8" by this pulse signal WP, and the changeover switch 43 is held in the ON state. When the starting ball enters the starting ball receiving chamber 5 in this state, a starting ball detection signal is output from the starting ball detection section 41,
This signal activates the timer 44, and a signal is supplied to the input terminal a of the motor drive circuit 45 to rotate the motor 14 in the normal direction for a certain period of time.

When the motor 14 rotates forward for a certain period of time in this way, the control arm 15 is moved to the position indicated by the two-dot chain line in FIG. to open. At the same time, the opening/closing plate 24 integral with the door plate 20 also rotates integrally, and the rear opening/closing plate portion 23B closes the starting ball opening 4 of the starting ball receiving chamber 5, as shown in FIG. 3B. Therefore, no further starting balls enter the starting ball receiving chamber 5 while the door 20 is open. At this point, the rotational drive of the motor 14 is stopped.

Balls falling on the board are guided by the open door plate 20 into the open prize-winning ball receiving chamber 8 and win prizes. This winning ball is discharged through the winning ball discharge port 9 and swings the detection lever 31 of the winning ball detecting device 30. The number of winning balls is counted by an up counter 46 as an electric signal output from the micro switch 32. This counter 46 has an initial value of "0" and is designed to count 10 from "1" to "10".
When the counted value reaches "10", the counter 46 outputs a count-up signal.

This count-up signal starts the timer 47 and supplies a signal to the input terminal b of the motor drive circuit 45 to reverse the motor 14 for a certain period of time. As a result, the control arm 15 moves to the solid line position in FIG.
0 in the closing direction to close the winning ball opening 1. At the same time, the opening/closing plate 24 integrated with the door plate 20 rotates integrally to open the starting ball opening 4 as shown in FIG.
A closes the opening window 7. The count-up signal output from the counter 46 is supplied to the counter 42 at the same time as the count value of the counter 46 is reset, and the initial value "8" is counted down to "7".

In this state, the changeover switch 43 is still held in the ON state. On the other hand, since the starting ball opening 4 is open, even if the winning ball does not enter the specific safe hole, if a starting ball enters any starting ball receiving chamber 5, the door plate 20 will be opened again. The operation of closing the door plate 20 when 10 balls have won the winning ball opening 1 is repeated.

The number of repetitions of the opening/closing operation of the door plate 20 described above is determined by the initial value "8" of the down counter 42. That is, down counter 4
When the count value in 2 reaches "0", one cycle of operation of the winning ball device ends. When the down counter 42 reaches "0" in this way, the changeover switch 43 is turned off. Therefore,
In this state, even if a starting ball enters through the open starting ball opening 4, the winning ball device will not operate.

FIGS. 5 and 6 show another embodiment of the present invention, and the same parts as in the first embodiment are given the same reference numerals and the explanation thereof will be omitted.

A support arm 5 extending upward from the side of the door plate 20
An opening/closing plate portion 52 is integrated into the upper end portion of the opening/closing plate portion 1 . The angle between this opening/closing plate part 52 and the door plate 20 is
As in the above-mentioned embodiment, this angle is equal to or less than the complementary angle of the swing angle of the door plate 20. Furthermore, this opening/closing plate portion 52
is a pachinko ball 1 falling on the board above it.
It is provided with a curved concave surface 53 sufficient to place the individual.

According to this embodiment, the opening/closing plate part 52 opens and closes the starting ball opening 4 for receiving the starting ball in accordance with the opening/closing operation of the door plate 20, as in the first embodiment, but the door plate A ball that comes toward the starting ball opening 4 which is a socket for the starting ball while the starting ball 20 is open is held as a preliminary starting ball P on the upper surface of the opening/closing plate part 52. Preliminary starting ball P held in this way
When the door plate 20 rotates in the closing direction, it comes into contact with the upper part 2a of the mounting plate 2 and is left sliding on the curved concave surface 53. When the door plate 20 passes the position indicated by the two-dot chain line in FIG. 6, the preliminary starting ball P falls under its own weight and enters the starting ball opening 4. Therefore, the next starting ball is held while the door plate 20 is open, and when the door plate 20 is completely closed,
Since the preliminary starting ball immediately falls into the starting ball opening 4 and the door plate 20 can be opened, the player can enjoy a thrilling game. Note that the present invention can equally be used in a winning ball device in which the door plate 20 is opened and then closed after a certain period of time.

[Effect of idea]

As described above, in the winning ball device of the present invention, the starting ball socket is closed while the door plate is open, and the starting ball socket is opened when the door plate is closed. . Therefore, even if you do not use a complicated credit system like in the past, when a certain number of opening operations of the door plate are reserved due to a specific winning, it is possible to ensure that the opening operation of the door plate is performed a certain number of times. This guarantees that players' interest will not be diminished. Moreover, in carrying out the present invention, there is no need to significantly increase the number of parts or increase the number of assembly steps, and the cost of the pachinko machine does not increase.
