Abstract

PURPOSE:To smoothly unobstructedly convert a movable member to a second state for ensuring high reliability and simple construction by providing an engaging section to give an early urging force for directing the movable member to the second state in the early drive of a solenoid between a lever and an operating member. CONSTITUTION:When a solenoid 64 for an opening and closing door 32 is turned on, an operating arm 101 works upward together with a rod 100 against a return spring 104 to open the door 32. When the solenoid is turned off, the operating arm 101 is lowered by a spring force and the weight of the rod itself and a hook 102 depresses a lever 79 to close the door 32. While the door 32 is opened by a weight 38 of a stopper 37 when the solenoid 64 is turned on, the upper tip of the hook 102 of the operating arm 101 abuts against a stage section 81 of a proximal end of the lever 79 of the door 32 when the door 32 is closed, so that the hook 102 springs up the lever 79 along with the rise of the operating arm 101 in the starting time to open smoothly the door 32 from the closed position to the opening position with the springing-up force.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable winning device for a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, a variable winning device is provided in a game area,
2. Description of the Related Art There is known a pachinko machine that converts a winning opening of a variable winning device into an open state when a predetermined game condition is satisfied to perform a special game.

As a movable member of such a variable winning apparatus, there is a door-shaped member which is supported at the winning opening through both ends of the lower portion so as to be freely opened and closed (see Japanese Patent Application No. 63-87423).

[0004]

In such a door-shaped movable member, when the solenoid is turned on, the operating member releases the lever of the movable member, whereby the lever moves forward by its own weight and opens. When is turned off, the returning operation member pushes the lever to the initial position to return to the closed state.

However, in this case, when the movable member is in the open state, the impact of the ball received by the movable member is not transmitted to the solenoid side, but it is opened only by its own weight. If there is a warp or the like, the movement may be poor and it may be difficult to open.

On the other hand, the movable member is provided with a weight in order to improve the response, but when the weight is removed by the impact of a ball or the like, the opening may be delayed or may not be opened.

Further, if a cigarette tar, oil or the like adheres to the movable member and sticks it to the substrate side of the apparatus, there is a concern that the movable member may remain closed instead of being opened.

The present invention aims to solve such problems.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a variable winning device for a pachinko machine having a movable member which can be converted from a first state to a second state by its own weight, and when the solenoid is driven, the lever of the movable member is moved. An operating member that pushes the lever to return the movable member to the first state when released from the driven state while being released is provided, and the movable member is provided between the lever and the operating member at the initial stage of driving the solenoid. Is provided with an engaging portion that applies an initial biasing force toward the second state.

In this case, it is advisable to provide a stepped portion at the base end of the lever to serve as an engaging portion.

[0011]

When the solenoid is driven, the operating member releases the lever of the movable member. However, the operating member moves the lever via the engaging portion at the initial stage of driving to apply the initial biasing force to the movable member toward the second state. Give.

That is, the driving force of the solenoid is applied to the movable member, so that the movable member is smoothly and promptly converted from the first state to the second state by its own weight.

In this case, the engaging portion is provided on the lever releasing side, but the structure is simplified by providing the engaging portion with the operating member at the base end of the lever having a small moving range.

Next, the control contents will be explained based on the flow charts of FIGS. In the flowchart, the variable display device 4 is called a special figure and the variable display 56 is called a general figure.

In the main routine of FIG. 23, each input process, output process, random number update, and branch process are executed (1.0
1, 1.03 to 1.05), the passage switches 51a and 51b for starting the universal figure, the starting switches 8 and 9a for starting the special figure,
The input of 9b is stored (1.06 to 1.11).

If there is a start-up memory for the universal figure, in the branch processing of FIG. 24, the universal symbol variation is set when the ordinary figure is normally displayed, and the routine proceeds to the universal figure processing (2.01 to 2.04).

Similarly, if there is a special figure starting memory, in the branching process, the special figure pattern variation is set when the special figure is normally displayed,
Proceed to special figure processing (2.05 to 2.08).

In the universal figure processing, based on the starting memory of the universal figure, the universal symbol variation (converted display) is started as shown in FIG. 25, and after a predetermined time elapses, the universal symbol determination is started (3.03, 3 .0
4).

In the universal symbol determination, as shown in FIG. 26, it is determined whether or not it is a hit based on the random number taken out when the passage switches 51a and 51b are input, and the universal symbol conversion display is stopped (5.
03-5.06).

At this time, when the open / close door 32 of the variable winning device 5 is open and the continuation blocking member 42 is in the retracted position, the universal figure conversion display is continued and the open / close door 32 is closed or the continuation blocking member 42 is opened. After reaching the previous position (after winning the continuous winning opening), the determination process is performed (5.01, 5.02).

Then, if the display pattern of the general figure is off,
When the display pattern hits, the general-purpose drawing operation such as turning off the light is performed (3.05), and the opening / closing blades 34a, 34b of the starting opening 6 are opened for a predetermined short time by the general-purpose hitting operation (3.06).

These processes are repeated every time there is a general starting memory.

On the other hand, in the special figure process, based on the starting memory of the special figure, the special figure change (converted display) is started as shown in FIG. 27, and after a predetermined time has elapsed, the special figure determination is started (4.0).
3, 4.04).

In the special symbol determination, start switches 8 and 9
Whether or not it is a big hit is determined based on the random numbers taken out when a and 9b are input, and the special figure conversion display (plurality) is stopped in order.

If the combination of the display symbols of the special figure is out, the special figure out operation such as turning off the light is performed (4.0).
5), when the combination of the display symbols is a combination of big hits, the big hit special figure big hit operation is started (4.0).
6).

If it is disengaged, the above-mentioned processing is repeated based on the starting memory of the special figure.

When the big hit occurs and the special figure big hit operation is started, the opening / closing door 32 of the variable winning device 5 is opened as shown in FIG. 28, and when the continuous winning switch 85 is turned on with the winning ball, the special game is allowed to continue. Turn on the continuation indicator lamp 90,
The continuation blocking member 42 is moved to the forward position (6.01 to 6.
03).

After the opening / closing door 32 of the variable winning device 5 is opened, the opening / closing door 32 is closed and the continuation blocking member 42 is retracted once when the number of winning balls in the special winning opening 31 is counted by a predetermined number or for a predetermined time. End the special game of (6.04,
6.05).

If continuation is possible by turning on the continuation winning switch 85, after the next set (6.06 to 6.0).
8) Then, the above-mentioned processing is entered again and the special game is repeated.

The special game of big hit is played a prescribed number of times (for example, 16 times) on condition that the continuous winning switch 85 is turned on. If the continuous winning switch 85 is not turned on, the jackpot is over at the end of the game of that time (6.09).

In this way, the pattern conversion of the variable display 56 is based on the passing balls of the passing ports 50a and 50b.
The symbol conversion of the variable display device 4 is started based on the winning of a and 7b, and when the symbol when the variable display 56 is stopped hits, the opening and closing wings 34a and 34b of the starting opening 6 are opened for a short time, and the variable display is performed. When the symbol when the device 4 is stopped is a big hit, a special game of a big hit is performed.

That is, if the sphere passes through the passage openings 50a and 50b and the design of the variable display 56 hits, the starting opening 6
The opening / closing wings 34a, 34b of the above are opened to increase the prize, and the chance of whether or not the jackpot is generated by the operation of the variable display device 4 is also increased. Therefore, the passage openings 50a and 50b
When the ball passes through, you can enjoy the double game mode.

On the other hand, if a big hit is generated based on the symbol of the variable display device 4, the open / close door 32 of the variable winning device 5 is opened, and the balls successively enter the special winning opening 31 from the open / close door 32. You can get a lot of balls. Then, when the number of prize balls reaches a predetermined number or when a predetermined time elapses, one special game ends and the opening / closing door 32 is closed, but the ball that has entered the special winning opening 31 during this period is the continuous winning opening in the center. If you win 40, you can continue the next special game.

In this case, the starting opening 6 is arranged above the continuous winning opening 40, but the ball on the ball receiving surface 44 of the opening / closing door 32 is guided to the center by the guiding portion 45 of the ball receiving surface 44. The winning prize 40 is won with a high probability. Therefore, the continuation of the special game is surely performed, and the jackpot does not end easily.

Further, once the continuous winning opening 40 is won, the continuation blocking member 42 advances to close the continuous winning opening 40, but it is possible to confirm that the continuation is possible due to the displacement, and the player feels uneasy. Never give.

When the enclosing wall 47 is provided on the guiding portion 45, a large number of spheres in the middle of winning a prize move on the sphere receiving surface 44, and particularly when the opening / closing door 32 is closed by the above-mentioned continuation blocking member 42. You can enjoy a lot of balls winning at once.

If the continuation is possible, the next special game is played and the opening / closing door 32 is opened again.

Although the special game is repeated a prescribed number of times in this way, if there is a passing ball in the passing ports 50a and 50b during this time, the variable display 56 is activated.

In this case, when the symbol of the variable display 56 hits, the opening / closing blades 34a, 34b of the starting opening 6 are opened for a short time, but during the special game, after the winning in the continuous winning opening 40 or the variable winning device 5 When the open / close door 32 is closed, the open / close wings 34a and 34b are opened.

Therefore, it is possible to prevent the continuous winning from being hindered, and when the opening / closing blades 34a and 34b of the starting opening 6 are opened after winning the continuous winning opening 40, the opening / closing door 32 and the winning opening are provided in two stages. Will be opened, which will result in a large number of prizes, more fun, and more varied games.

When the opening / closing door 32 is closed, the starting opening 6
When the opening / closing wings 34a, 34b of the above are opened, the opening / closing wings 34a, 34b are opened at intervals such as when the previous special game is finished and the next special game is started. During the interval when the door 32 is closed, you can continue to enjoy a variety of fun games,
Players can be given a high level of satisfaction by winning those that were conventionally out balls.

The opening / closing wing 34 of the starting opening 6 during the special game
The opening timing of a and 34b may be set at random between the winning of the continuous winning opening 40 and the closing of the opening / closing door 32.

In this way, the game and the special game at the time of a big hit can be enjoyed and the interest can be sufficiently enhanced.

When the opening timing of the opening / closing blades 34a, 34b of the starting opening 6 is delayed, the conversion display of the variable display 56 is continued, so that there is no unnaturalness.
