Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a winning ball device provided in the center of a game board of a pachinko machine.

[Prior Art] Movable pieces are pivoted to face each other on the front left and right sides of a mounting board, and the movable pieces are moved by an electric drive source to a first state in an upright state that does not accept a hit ball and a first state in a horizontal state that can accept a hit ball. A prize winning ball device that converts the winning ball into the second state is known, for example, from Japanese Patent Application Laid-Open No. 112571/1983.

[Problems to be solved by the invention] The left and right movable pieces of this prize winning ball device are individually connected to a drive source, such as a plunger of a solenoid, through appropriate link mechanisms on the back side of the mounting board.
By energizing the solenoid, the state is converted to a horizontal second state. The opening angle is regulated by the link mechanism and the stroke of the plunger. Therefore, if play occurs in the link mechanism, the opening angles of the left and right movable pieces will become uneven or the opening angles will become too large, resulting in inconvenience in receiving the ball.

[Means for solving the problem] The present invention has a transparent plate attached to the front surface of the mounting board on which the movable piece is pivoted, and the upper edge of the transparent plate is attached to the front surface of the movable piece when the movable piece is converted to the second state. A stopper piece that comes into contact with is provided.

[Function] When the movable piece is converted to the second state, the stopper piece comes into contact with the upper edge of the transparent plate and always regulates the opening angle of both movable pieces to be constant.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. In the figure, 1 is a mounting board, 2 and 2 are a pair of movable pieces pivoted oppositely on the front left and right sides of the mounting board 1, and 3 is a mounting board 1 located between both movable pieces 2 and 2.
4 and 5 are chaser members having prize openings located at the upper and lower parts of the openings and provided on the front surface of the mounting board 1; 6 is a box frame; 5 shows a swinging body that is provided to be swingable from side to side. The movable pieces 2, 2 have support shafts 7, 7 fixed approximately in the middle of their lengths on the mounting board 1.
The pinions 8, 8 are respectively fixed to the protruding ends thereof, and the pinions 8, 8 are integrally connected to the plungers 10, 10 of the solenoids 9, 9, which are the driving sources. The racks 12, 12 of the L-shaped members 11, 11 are engaged with each other. The plungers 10, 10 are always urged upward by springs 13, 13 wound around them, thereby causing the movable pieces 2, 2 to accept falling balls as shown by solid lines in FIG. When the plungers 10, 10 are held in the first upright state, and the plungers 10, 10 are sucked downward by the excitation of the solenoids 9, 9, the racks 12, 12 rotate the pinions 8, 8,
As a result, the movable pieces 2, 2 are rotated horizontally as shown by the chain lines in FIG. 1, and converted to the second state in which the ball can be received.

14 is a support shaft of the swinging body 6; 15 is an engagement pin protruding slightly above the support shaft 14, and is connected to a lever piece 16 that swings about the support shaft 14 on the back surface of the mounting board 1; has been done. 17 is a motor, and 18 is a cam disc fixed to the motor shaft 19, the engaging protrusion 20 of which faces a long hole 21 formed in the lever piece 16, and the cam disc 18 is driven by the motor 17. When rotated, the engagement protrusion 20 engages with the elongated hole 2.
1 while sliding the lever piece 16 from side to side,
This causes the swinging body 6 to swing left and right. The swinging of the swinging body 6 causes a change in the manner in which the hit balls received on the movable pieces 2, 2 which have been converted to the second state win a prize.

Therefore, in the present invention, a transparent plate 22 made of synthetic resin or the like is fixed to the front surface of the mounting board 1 on which the movable pieces 2, 2 are attached with screws 23. As shown in the figure, the transparent plate 22 covers the front part located below the middle of the length of the movable pieces 2, 2, and
The movable pieces 2, 2 are formed in such a size that they extend close to the tips of the movable pieces 2, 2 that have been changed to the state. On the other hand, the movable piece 2,
Stopper portions 24, 24 protruding from the upper surface edge to the front are integrally formed at the tip portions of 2. These stopper parts 24, 24 are located above the transparent plate 22 when the movable pieces 2, 2 are in the first state, and are in contact with the upper edge of the transparent plate 22 as shown by the chain line in FIG. 1 when the movable pieces 2, 2 are in the second state. come into contact with

The present invention is based on a mounting board 1 on which movable pieces 2, 2 are pivoted.
A transparent plate 22 is attached to the front surface of the movable pieces 2, 2, and stopper parts 24, 24 are formed on the front faces of the movable pieces 2, 2, so that when the movable pieces 2, 2 are converted to the second state, the stopper parts 24, 24 are made transparent. It is made to abut against the upper edge of the plate 22, thereby making it possible to always regulate the opening angle of both movable pieces 2, 2 to a constant value.

[Effects of the invention] Therefore, according to the invention, even if the link mechanism that converts the movable pieces to the second state has looseness as in the conventional device, the opening angles of both movable pieces become uneven or the opening angles of the two movable pieces become uneven. There is no risk of overshooting, and reliable operation can be expected over a long period of time without causing the slightest hindrance to the ball receiving operation.
