(The shaft 7 is a boss 21 protruding from the back of the base plate 3.
The arm members 20, 20' are bent at right angles at positions corresponding to the pair of lower cutouts 8, 8', and the arm members 20, 20' are bent at right angles at positions corresponding to the pair of lower cutouts 8, 8'. , 8', one end of each protrudes in front of the base plate 3, and a pair of lower support frame members 22, 22' are supported on these protruding ends, respectively. The other end of the arm member 20, 20', that is, the shaft 7
A drive device is attached to each of the locations where the arm members 20 and 20 are pivoted.
20' is designed to be able to rotate around the shaft 7. Each of the arm members 20 and 20' has a return spring 2 whose one end is fixed to the base plate 3.

The arm members 20, 20' and the lower receiving frame members 22, 22' are returned to their original states by the return forces of the return springs 23, 23', 26, 26' (see FIG. 2). Arm members 20, 20' and actuating piece 20
a and 20a' are integrally formed in a bent state with a slight phase shift as shown in the figure, so that the lever mechanism can be easily rotated about the shaft 7. Similar to the arm members 11, 11', the base plate 3 has a pair of lower cutouts 8, 8' where the shaft 7 is attached so as not to interfere with the rotation of the arm members 20, 20'. The long notches 8 and 8' are formed in the shape of an arc with the center of curvature, and the long notches 8 and 8' are formed over the rotational range of the arm members 20 and 20'. Further, the range of rotational movement of the arm members 20, 20' is restricted by the arm members 20, 20' themselves being attached to the terminal ends of the lower cutouts 8, 8', as in the case of the arm members 11, 11'. This may be done by abutting or link pieces 25, 2
This may be done by restricting the movement of 5'.

In addition, as a drive device for the arm members in this embodiment, the arm members 11 and 11' are connected to the solenoid 1.

' may be a lever mechanism, arm members 20, 20' may be gear mechanisms, and arm members 20, 20' may be a gear mechanism.
In this case, the link pieces 25, 25' are connected to the actuating pieces 20a, 20a' and are driven by two solenoids. By driving the lever rod with one solenoid, it is also possible to simultaneously drive both arm members 20, 20' with one solenoid. Further, if the object of the present invention is achieved, the present invention is not limited to this, and for example, each arm member 11, 11', 20, 20' may be directly rotationally driven by a small motor or the like.

The prize-winning device D according to the present invention is configured as described above, and the player hits a pachinko ball in the supply tray I using the operation dial K, and the ball hits the specified prize-winning hole E or the prize-winning chuck car F. When a predetermined specific mode is reached, the solenoids 17, 17', 24,
24' are controlled to be energized simultaneously or selectively, and a batted ball winning device having a large winning entrance appears. For example, in response to a particular pattern of the ball being hit, the control device 50 controls the solenoids 17, 17',
24, 24' are all energized, each link piece 18, 18', 25, 25' rotates the gear mechanism and the lever mechanism, and the pair of upper support frame members 12, 12' and the lower part are rotated. The receiving frame members 22, 22' are moved from the state shown in FIG. 2 to the state shown in FIG.

The state shown in FIG. 4 is that each receiving frame member 12, 12', 2
2, 22' gather toward the prize opening 10 and surround it, and in particular, the upper receiving frame members 12, 12' form a winning entrance with a sufficient interval 1 for the ball to flow down, and the lower receiving frame member 22 , 22' approach each other at the lower part of the winning opening 10, and the lower receiving frame members 22, 2
2' and the prize opening 10 are in communication,
This is a second state in which a guide path is formed to catch the falling batted ball and introduce it into the winning hole 10, and it is possible to win a prize by introducing the hit ball into the winning hole 10 with an extremely high winning rate. Therefore, if the balls hit by the player one after another fall within the range of the interval l, the balls will be guided by the left and right upper receiving frame members 12, 12', received by the lower receiving frame members 22, 22', and enter the winning hole 10. Wins a prize, or is directly received by the lower receiving frame members 22, 22' and enters the winning slot 10.
A winning device with an extremely high winning rate will appear.

Next, the control device 50 sets the solenoid 17, 17',
When the biasing of 24, 24' is stopped, each receiving frame member 1
2, 12', 22, 22' rotate together with the respective arm members 11, 11', 20, 20' by the return force of the return spring, and the ball shown in FIG. Returns to the first state in which winnings are not possible. The state shown in FIG.
The communication state with the winning hole 10 is broken and a guide path to the winning hole 10 is not formed, and the batted ball continues to flow in front of the winning hole 10, and there is a possibility of winning only when the upper receiving frame members 12, 12' are aligned. Only the winning openings 9 and 9' are in the state shown in FIG. 4, and the winning rate is extremely low compared to the state shown in FIG. In addition, if the winning holes 9 and 9' are not provided, the ball will not enter the winning device D according to the present invention unless the ball collides with a receiving frame member, an obstacle nail, etc. and directly jumps into the winning hole 10. but,
There is a possibility that the batted ball is temporarily caught by the batted ball placement portion of the upper receiving frame member 12, 12', and in this case, the batted ball that is caught is then changed to the state shown in FIG. 4 by the winning device D as described above. It will be fun to enter the winning slot 10 and win the prize.

Finally, solenoids 17, 17', 24, 2
The electrical control device 50 for controlling the energization of the motor 4' will be explained. The control device 50 controls the solenoids 17, 17', 24,
Any type of device may be used as long as it can control 24' with various changes, and various known types can be adopted. Here, when a batted ball wins a prize in the specific winning hole E, the upper receiving frame members 12, 12' and the lower receiving frame members 22, 2
2' continuously or intermittently for a certain period of time.
On the other hand, when the winning chaser F wins a prize, the lower receiving frame members 22, 2
An embodiment of a control device that can selectively change only the signal 2' continuously or intermittently for a certain period of time to the state shown in FIG. 5 will be described with reference to FIG.

The control device 50 shown in FIG.
4, 55, 56, differentiating circuits 57, 58, timers 59, 60 as timer means, AND gate 61,
62, driver circuits 63 and 64, and a pulse oscillator 65. The switch 51 is provided near the back side of the specific winning hole E, and
The switch 52 and the switch 53 are also known winning ball detection switches that detect winning balls that have landed on the winning ball F that is provided on the lower left and right sides of the game board 1. The switch is for detecting that the ball has been hit in a particular manner and sending a signal accordingly to the control device 50.

First, if a ball hits the special winning hole E, the signal from the switch 51 is applied to the timer 59 via the diode 54 and the differentiation circuit 57 on the one hand, and the signal is applied to the timer 59 via the diode 55 and the differentiation circuit 58 on the other hand. added to timer 60. timer 5
9 and timer 60 each derive a high level signal for a certain period of time based on the signals from differentiating circuit 57 and differentiating circuit 58, and these derived signals are applied to one input of subsequent AND gates 61 and 62, respectively. The other input of the AND gate 61 and the AND gate 62 is connected to a pulse oscillator 65 (the pulse period is one pulse, and the receiving frame members 17, 17',
24, 24') is constantly applied, the outputs of AND gate 61 and AND gate 62 remain constant for a certain period of time determined by timer 59 and timer 60. During this period, the driver circuit 63 and the driver circuit 64 are intermittently turned on and off. Solenoids 17 and 17' are connected to the driver circuit 63, and solenoid 2 is connected to the driver circuit 64.
4, 24' are connected, the receiving frame members 17,
17' and 22, 22' repeat the states shown in FIGS. 2 and 4 intermittently for a certain period of time. In this case, if the time for the timer 60 to derive the high level signal is selected and set to be longer than the time for the timer 59 to derive the high level signal, all receiving frame members 17 ,17',2
After 2 and 22' repeat the fluctuations shown in FIGS. 2 and 4 for a certain period of time (time determined by timer 59), only the lower receiving frame members 22 and 22' change as shown in FIGS. 2 and 5. The fluctuation is further repeated for a time corresponding to the difference between the two times, and it is possible to provide the player with a game rich in variety.

Next, if the hit ball wins a prize in the winning chaser F, the signal from the switch 52 or switch 53 is applied only to the timer 60 via the diode 56 and the differentiation circuit 58. This is different from the case described above in which the winning signal is applied from the switch 51 to the control device 50.
This is because the diode 55 is in the opposite direction with respect to the signal from. The timer 60 derives a high level signal for a certain period of time based on the signal from the differentiating circuit 58. This derived signal is applied to one input of the AND gate 62, and the pulse signal from the pulse oscillator 65 is constantly applied to the other input, so the output of the AND gate 62 is applied to the timer 60.
The driver circuit 64 is intermittently turned on and off for a certain period of time determined by . As described above, the solenoids 24 and 24' for rotating the lower support frame members 22 and 22' are connected to the driver circuit 64, so the support frame members 22 and 22'
The fluctuations shown in FIGS. 2 and 5 are repeated intermittently for a certain period of time during which a high-level signal is derived. still,
There is no need to intermittently change the receiving frame members, and depending on the occurrence of a specific condition, each receiving frame member can be changed to
4 or 5 for a certain period of time.
If it is only necessary to maintain the state shown in the figure, the pulse oscillator 65 and AND gates 61 and 62 are unnecessary, and the electrical control device 50 can have an extremely simple configuration.

In addition, in the above-mentioned embodiment, it was explained that the winning device D is activated according to the present invention when a hit ball wins a prize in the specific winning hole E or the winning chaser F, but this is just an example, and other game modes may be used. Of course, it may be. In the circuit shown in FIG. 6, which is an embodiment of the control device, the operation of the prize-winning device D is stopped after a certain period of time has elapsed, but for example, when a certain number of balls hit the prize-winning device D, It is also possible to use a control device that uses this as a stop condition to stop its operation. Further, in this embodiment, there are four receiving frame members, one pair each on the upper and lower sides, but it is also possible to provide only one pair or four or more receiving frame members. Furthermore, it is also possible to provide only one receiving frame member and change the state between a first state in which it is difficult or impossible for a batted ball to enter the prize opening and a second state in which a batted ball can enter a prize.

〔Effect of the invention〕

As explained above, the batted ball winning device according to the present invention includes a base plate in which a winning hole through which a batted ball wins and a long notch located near the winning hole, and an electric a drive device equipped with a driving source; and a receiving frame connected to the drive device via an arm member protruding through the notch and movable on the front side of the base plate within the range of the notch. member, and when the electric drive source is in a non-energized state, the receiving frame member is separated from the winning hole to maintain a first state in which it is difficult or impossible for a batted ball to enter the winning hole. On the other hand, when the electric drive source is in an energized state, the drive device operates to move the arm member along the length, so that the receiving frame member communicates with its placement portion and the entry prize opening. The surface of the base plate is moved so as to change the state to a second state in which a hit ball can be introduced into the winning hole to win a prize. Therefore, this batted ball winning device is a winning hole in which it is difficult or impossible for a batted ball to enter a prize in the normal state, but by operating the drive device, the receiving frame member enters the winning hole from an unexpected place. By moving against the ball, a winning hole with a high winning rate is instantly formed, giving the player a chance to generate a large amount of winning balls, and the receiving frame member moving greatly can provide an interesting and unexpected feeling. can.

Furthermore, when a pair of receiving frame members are provided, each receiving frame member is assembled together with respect to the winning hole, and a second state is formed in which it is possible to win a prize by introducing a batted ball into the winning hole, each receiving frame member is large. In addition to the fun of moving, there is a double visual fun of being able to form a prize opening with an unexpected shape that is not obvious beforehand, and can greatly increase the interest of the game.

Furthermore, this batted ball winning device has a second state in which, when the electric drive source is in the energized state, the drive source is activated and moves the receiving frame member toward the winning hole, and the ball is introduced into the winning hole to win a prize. The electric drive source is de-energized and the receiving frame member is moved from the winning hole by controlling the energization according to the activation stop condition based on the elapse of a certain time set in the timer means and the fact that a certain number of batted balls have entered the winning hole. Since the ball is separated from the winning hole and returns to the first state where it is difficult or impossible for the ball to enter the winning hole, it is possible for each player to play a game in which the player aims at the winning hole that is in the second state under the same conditions. In addition to giving the player a sense of expectation of winning a large amount of prize balls by letting many batted balls enter the winning slot within a certain period of time, the player can also Since the receiving frame member is separated from the winning hole and the ball winning device is returned to the first state, it is possible to balance the profits of the player and the game parlor.
