Abstract

PURPOSE:To reduce calorific value and energy consumption and to prevent balls from being clogged by providing a driving motor to change a ball receiving member from a hit ball receivable state to a non-receivable state and an energizing member to change the ball receiving member to the reverse states, driving the motor based on a drive start detecting member and stopping motor in the state that hit balls are not received. CONSTITUTION:A driving motor 72 is operated to the change of ball receiving members 58a and 58b from the second state not to receive the hit balls to the first state to receive the balls and the change from the first state to the second state is executed by the operation of the energizing member 67. Even when the balls are turned to a clogged state in the middle of the change, load caused by the clogged state is only generated by the energizing member 67 and excess force is not applied to the driving motor 72 or ball receiving members 58a and 58b. The driving motor 72 starts driving based on the output of a drive start detecting means 47 and when there is the output of a detecting means 77 to detect the first state, however, the driving motor 72 is stopped for a prescribed period. Accordingly, even when the first state is continued for a long time, power is not supplied during such a period. Thus, the calorific value and energy consumption is reduced and operation is economic.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a ball that can change into a first state in which a hit ball can be accepted in a winning area and a second state in which a hit ball cannot be accepted. The present invention relates to a pinball game machine equipped with a variable winning ball device equipped with a receiving member.

[Prior Art] Conventionally, a variable winning ball device is provided with a ball receiving member that can change between a first state in which a ball can be received in a winning area and a second state in which a ball cannot be received in a winning area. A type of pinball game machine in which a ball receiving member is driven by a solenoid has been offered on the market. In such a pinball game machine, especially when the first state in which a ball can be received is relatively long, power must be continuously supplied to the solenoid during the first state. Therefore, the solenoid generates a large amount of heat, which may adversely affect parts placed near the solenoid (the membrane is made of synthetic resin), or increase power consumption, making it uneconomical. Ta. Therefore, it is conceivable to perform the drive motor 31 by replacing the drive source for driving the ball bearing member with a solenoid because it generates less heat and is economical.

[Problems to be Solved by the Invention] However, when the ball receiving member is driven by a drive motor, when transitioning from the first state to the second state, the ball receiving member and the ball receiving member disposed above the ball receiving member are A ball-locking phenomenon may occur between the winning control frame and the winning control frame, and in such a case, if the drive motor and ball receiving member are directly connected via a link mechanism, the electric drive source Unreasonable force is applied to a certain drive motor or ball rest, which may cause damage to the drive motor or ball rest even after very short periods of use, or the ball rest may not operate smoothly. There was a problem.

This invention was made in view of the above-mentioned problems, and aims to be economical with low heat generation and power consumption, and to provide a ball receiving member capable of receiving a ball to prevent the ball from being caught. To provide a pinball game machine equipped with a variable winning ball device which does not apply unreasonable force to a ball receiving member or a drive motor for driving the ball receiving member even if the ball receiving member is raised.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the pinball game machine according to the present invention has two states: a first state where a hit ball can be accepted in the winning area and a first state where the hit ball cannot be accepted. The variable winning ball device is equipped with a ball holder member that can be changed into a second state, and a drive motor that changes the ball holder member from the second state to the first state; a biasing member that causes the receiving member to change from a first state to a second state; a detection means that detects that the ball receiving member is in the first state; and a drive that detects the start of driving of the drive motor. A drive control means that starts driving the drive motor based on the output of the drive start detection means and stops driving the drive motor for a predetermined period when there is an output of the detection means. It is characterized by:

[Function] Changes in the ball bearing member are made by the drive motor and the urging member, and the drive motor only acts on the transition of the ball bearing member from the second state to the first state ♂. , since the transition from the first state to the second state is performed only by the action of the biasing member, even if a ball-locking state occurs during the transition, the resulting load will be absorbed by the biasing member. There is no need to apply excessive force to the drive motor or ball bearing member.

Further, the drive motor starts driving based on the output of the drive start detection means, but is stopped for a predetermined period when there is an output of the detection means that detects that the first state is reached. Even if the state is relatively long, power is not supplied during that time, so there is less heat generation and less power consumption, which is economical.

Next, with reference to FIGS. 1 to 4B, the configuration of the variable winning ball device 40 that constitutes the main part of this embodiment will be explained. First, the overall configuration of the variable winning ball device 40 will be explained with reference to FIGS. 2 and 3. In the figure, the variable winning ball device 40 has a mounting board 41 that is attached to the game board 10, and a winning regulation frame 42 is protruded from the top of the mounting board 41. A normal winning hole 43 is formed on the upper surface of this winning regulation frame 42, and a winning number display 44 (7 segment LE
D) and a starting memory display 45 that stores and displays a maximum of four allowed rotation times of the rotary drums 48a to 48c based on the winning balls won in the starting winning holes 13a to 13c is arranged so as to face.

A horizontally long rectangular opening 46 is provided in the center of the mounting board 41, and a variable display device 47 is provided so as to face the opening 46. The variable display device 47 houses a plurality of (three) rotating drums 48a to 48c driven by a drum motor 50, and the rotating drum 48a
It has a drum mechanism 49 that includes a detection means for detecting the combination of identification information drawn on the outer periphery of the rotating drums 48a to 48c and a stop mechanism that stops the rotation of the rotating drums 48a to 48c. In addition, the drum mechanism 49 is integrated with the aforementioned entered prize ball collecting cover 2.
1 with screws or the like.

In addition, since the variable display device 47 is provided so as to be included in the variable winning ball device 4o, the ball receiving member 58 during the specific game state

Furthermore, a winning ball receiving frame 51 that surrounds both sides and the bottom of the opening 46 is provided on the mounting board 41 in a protruding manner. The area surrounded by the winning ball receiving frame 51 constitutes the winning area. A plurality of winning holes are formed below the winning ball receiving frame 51, with a specific winning hole 52 in the center and normal winning holes 53a and 53b on the left and right sides, respectively.

A specific person prize ball detector 54 is integrally provided in the specific winning hole 52, and on the condition that the specific person prize ball detector 54 is turned on, the ball receiver members 58a, 58b are activated in a predetermined manner. State 1 (opening until 20 seconds pass or until 10 winning balls are generated) can be repeated a predetermined number of times. In addition, a ball dropping board 55 is lying on the upper part of the specific winning opening 52 and the normal winning openings 53a, 53b, and the ball receiving member 58a, Winning balls falling from 58b are guided to respective winning holes 52, 53a and 53b. That is, some of the winning balls guided by the ball receiving members 58a and 58b do not fall directly into the specific winning hole 52 or the normal winning holes 53a and 53b, but instead collide with the ball falling plate 55 and bounce up. After winning, the player enters one of the winning ports 52, 53a and 53b from the guiding opening 56. This makes the game more interesting by changing the trajectory of the winning balls falling.

Further, on the mounting board 41, a pair of ball receiving members 58a58b are slidably provided between the winning ball receiving restriction frame 42 and the winning ball receiving frame 51. These ball bearing members 58a and 58b are
a horizontal guide elongated hole 57a drilled in the mounting board 41;
57b, and when they slide inward, the tip portions of the ball receiver members 58a, 58b touch the winning regulation frame 4.
2 and the winning ball receiving frame 51, and the ball is not accepted into the winning area, and in the state where the ball is slid outward (the state shown in FIGS. , the ball receiving member 58a, 58b is in a first state where the ball P2 falling in the game area 12 can be received by the ball receiving members 58a, 58b and guided to the winning area.

Here, the mechanism that causes the sliding movement of the ball receiving members 58a, 58b will be explained with reference to FIGS. 1 to 4B. Guide bins 59a, 59 passing through
b and an operating bin 60a60b are protrudingly provided, and the guide bin 5
A clamping plate 61a that clamps the guide elongated holes 57a, 57b at the rear of the operating bins 9a, 59b and the operating bins 60a, 60b.

61b is fixed with a screw. That is, the ball receiving member 5
8a, 58b and the holding plates 61a, 61b form the guide elongated hole 5.
By sandwiching 7a and 57b, ball bearing members 58a and 5
8b can be slid along guide elongated holes 57a and 57b. By the way, the operating bin 60 provided with a protruding inner side C
a, 60b pass through the holding plates 61a, 61b and protrude further rearward, and the actuating pins 60a, 60b are inserted into engagement elongated holes 64a, 64b formed at the lower ends of the rotation link members 63a, 63b. engaged.

The rotation link members 63a, 63b are formed in a dowel shape, and the bent portion thereof is a support shaft 62a that protrudes from the upper rear surface of the mounting board 41.

It is rotatably supported by the shaft 62b. Thus, the lower ends of the long sides of the rotation link members 63a, 63b have engaging elongated holes 64a, 64b into which the operating bins 60a, 60b are loosely fitted.
are formed, and engagement pins 65a, 65b extending rearward are provided on the short sides (bent inwardly as shown in FIG. 1) of the two. Also, key-shaped spring locking portions 66a, 66b are formed approximately at the center of the long sides of the rotation link members 63a, 63b, and act as biasing members that are attracted to each other. The spring 67 is loaded. As shown in FIG. 4A, the spring 67 biases the lower ends of the rotating link members 63a and 63b inward, so that the ball bearing members 58a and 58b are always in the second state. is energized. Also, at this time, the engagement bins 65a, 6
5b is in an elevated position. Note that instead of the spring 67 as the biasing member, for example, a rotating member 6 may be used.
A weight may be provided on the side opposite to the short side of 3a, 63b, and the ball bearing members 58a, 58b may be urged to the second state by the urging force of the weight. Also, spring 6
The attachment position 7 may not be the rotation link members 63a and 63b, but may be, for example, hooked so that the holding plates 61a and Bib are attracted to each other.

On the other hand, guide grooves 68a, 68b are formed on the back surface of the input prize ball collection cover 21, and the guide grooves 68a, 68
A sliding link plate 69 is provided so as to be slidable up and down along the direction b. This sliding link plate 69 has engagement elongated holes 70a, 70b bored in the middle on the left and right sides, and the engagement elongated holes 70a,
The engagement pins 65a65b of the rotary link members 63a, 63b are loosely engaged with 70b. As a result, when the sliding link plate 69 is in the highest position, the ball bearing members 58a, 58b are shown in FIG. 4A.
is in the second state, and when the sliding link plate 69 is in the lowest position, the ball bearing members 58a, 58b are in the first state as shown in FIG. 4B. Further, an abutting protrusion 71 is provided on the rear surface of the sliding link plate 69 between the engagement elongated holes 70a and 70b at right angles to the sliding link plate 69. An operating pin 75, which will be described later, is adapted to engage and disengage from this abutting protrusion 71.

A drive motor 72 is fixed to a motor mounting plate 79 (see FIG. 6) attached to the back surface of the entered prize ball collecting cover unit 21, and a motor output shaft 73 protruding in front of the motor mounting plate 79 has a circular rotating shaft. A cam 74 is fixed. An operating pin 75 is protruded from a point near the outer circumference of the rotating cam 74, and the operating pin 75 engages with and disengages from the abutting protrusion 71.

This engagement/disengagement relationship will be explained in detail with reference to FIGS. 4A and 4B. First, the positional relationship between the rotary cam 74 and the abutting protrusion 71 is such that at least the abutting protrusion 71 is connected to the motor output shaft. 73 (the side where the actuating pin 75 engages with the abutting protrusion 71 from above due to rotation), and the length of the abutting protruding piece 71 is longer than that of the motor output shaft 73 and the actuating bin 75.
The length is set to correspond to the distance between By establishing such a positional relationship, the rotation of the rotary cam 74 (the fourth A
(clockwise in the figure), the operating pin 75 and the abutting protrusion 7
1 engages and moves the sliding link plate 69 downward against the biasing force of the spring 67, whereby the ball bearing member 58a
, 58b from the second state to the first state. When the operating bottle 75 is at its lowest position, the sliding link plate 69 is also at its lowest position, and the ball bearing members 58a and 58b are also at their most open position.

When the drive motor 72 further rotates from such a state, the engagement state between the operating pin 75 and the abutting protrusion 71 is released. When this engagement state is released, the urging force of the spring 67 as an urging member causes the rotation link members 63a, 6
The lower ends of the ball bearing members 58a and 5 are drawn together.
8b is suddenly shifted from the first state to the second state, and the sliding link plate 69 is also raised as the engaging pins 65a and 65b are raised. In addition, in the illustrated embodiment,
Even when the sliding link plate 69 is in the highest position, the abutting protrusion 71 is located slightly below the motor output shaft 73. Since the engagement is made from above, this is to ensure that the engagement is performed smoothly, and the drive motor 72
This is to avoid placing an extra load on the Of course, the abutting protrusion 71 may be positioned slightly above the motor output shaft 73. In addition, when the ball bearing members 58a and 58b return from the first state to the second state, the urging force of the spring 67 is more effective than in the conventional case where the ball bearing members 58a and 58b return slowly while being connected to the solenoid. Since it is configured to return suddenly, in a variable winning ball device of the type that closes the ball receiving member when a predetermined number of winning balls are generated, as in this embodiment, when the ball receiving member moves, Since the number of winning balls generated during each opening/closing operation can be reduced, the number of winning balls in one opening/closing operation can be accurately determined.

By the way, in this embodiment, the ball bearing members 58a, 5
In order to detect that the rotary cam 8b is in the first state, a light shielding plate 76 is provided on the outer periphery of the rotary cam 74, and a stop position detector 77 operated by the light shielding plate 76 is provided. The stop position detector 77 is a light emitting/receiving type detector and includes a light receiving element 78 . The light shielding plate 76 is formed in a fan shape extending approximately 90 degrees rearward from the opposite side of the operating bin 75 . In a normal state, the tip of the light-shielding plate 76 shields the light-receiving element 78, turning off the stop position detector 77, as shown in FIG. 4A. In this state, the sliding link plate 69 is at its highest raised position, and the operating pin 75 and the abutting protrusion 71 are in almost contact position. When the output to start the rotation of the drive motor 72 is applied manually in such a state, the operation bin 7
5 and the abutting protrusion 71 immediately engage with each other, and the sliding link plate 69
is slid downward to shift the ball bearing members 58a, 58b from the second state to the first state. Then, as shown in FIG. 4B, when the rear end of the light-shielding plate 76 releases the shielding of the light-receiving element 78 at a position where the rotary cam 74 has rotated approximately 90 degrees, the stop position detector 77 changes from OFF to ON. By detecting this, the driving of the drive motor 72 is immediately stopped.

When the driving of the drive motor 72 is stopped, the engagement state between the operating pin 75 and the abutting protrusion 71 is maintained as it is, and the sliding link plate 69 is at the lowest position, so that the ball holder is Member 58a.

58b is in the first state. And ball support member 5
A predetermined period of time (20
When a predetermined number (10 seconds) has elapsed or a predetermined number (10) of winning balls have been generated, a drive start signal is sent to the drive motor 72 again, and the rotation starts. When the drive motor 72 starts rotating, the engagement between the operating pin 75 and the abutting protrusion 71 is released, and as described above, the ball bearing members 58a and 58b are suddenly brought into the first state by the urging force of the spring 67. to the second state. Further, even after the engagement state is released, the drive motor 72 continues to rotate, and the tip of the light shielding plate 76 shields the light receiving element 78 again, changing the stop position detector 77 from ON to OFF. Sometimes the rotation is stopped. In other words, the rotation is stopped when the state returns to the state shown in FIG. 4A.

As mentioned above, in this embodiment, the ball bearing member 58
a and 58b are held in the first state for a relatively long time, but during that time, no power is supplied to stop the driving of the drive motor 72, so the drive motor 72 does not generate heat. It is economical because it does not adversely affect the components placed therein and can save power consumption.

In addition, the above-mentioned stop position detector 77 is connected to the ball receiving member 58a.
, 58b, but also the second state as a result, it is also possible to detect either one of the states. For example, the fourth
Even if a detector is provided that detects only the second state shown in Figure A, it is extremely easy to detect the first state by energizing for a predetermined period of time from the start of rotation; Even if a detector is provided to detect only the first state, it is extremely easy to detect the second state by applying electricity for a predetermined period of time from the start of rotation. Of course, these controls may be performed by a microcomputer provided on the control board 31. In addition, the drive motor 7
By configuring 2 with a stepping motor, its control can be made easier.

The configuration of the variable winning ball device 40 according to the embodiment has been described above, but according to this embodiment, the ball receiver member 58a
, 58b, the change from the second state to the first state is performed by the drive motor 72, and the change from the first state to the second state is performed by the drive motor 72.
Since the configuration is configured such that the change to the state is performed by the spring 67 as a biasing member, the ball bearing members 58a and 58b are in the first state.
When transitioning from the state to the second state, as shown in FIG.
8a, 58b and the winning regulation frame 42, and even if a ball-locking state occurs, at the time when the ball-locking state occurs, the abutment between the operating bin 75 of the rotary cam 74 and the sliding link plate 69 Since the engagement with the piece 71 is released, the load caused by the ball engagement is not transmitted to the drive motor 72, and
Only the biasing force of the spring 67 is transmitted to the ball bearing members 58a and 58b. That is, since no excessive force is applied to the drive motor 72 or the ball bearing members 58a, 58b, they will not be damaged in a short period of time and can be used stably for a long period of time.

In addition, in the above-described embodiment, the ball receiving member 58a.

Although a type in which the 58b slides in the horizontal direction is shown, it may also be a type of ball bearing member that rotates around a rotation axis or a type of ball bearing member that opens and closes in the front and back direction. In addition, variable winning ball device 4
The structure of No. 0 may also have only one winning area instead of having a plurality of winning openings, and may further include a variable display device 47 provided separately.

[Effects of the Invention] As is clear from the above explanation, the pinball game machine according to the present invention uses a drive motor to shift the ball receiver member from the second state to the first state, and From state 1 to state 2
Since the transition from the first state to the second state is caused by the biasing force of the biasing member, even if a ball jamming state occurs when transitioning from the first state to the second state, the excessive force will not be applied to the drive motor or the ball. Not only does it not get caught on the receiving member and will not be damaged in a short period of time, but it can be used stably for a long period of time. Furthermore, since the drive motor is configured to stop rotating when the ball bearing member is in the first state, the first
Even if the state of It has the advantage of being
