A batted ball firing device for firing a ball in the ball firing device is provided separately, and the ball feeding device and the batted ball firing device are connected in order to synchronize the timing of firing the batted ball and supplying the balls. As a result, the structure of the pachinko machine becomes complicated and bulky.

This project was proposed in view of the above, and includes an operating cam that is rotatably driven by a drive device above the ball firing position formed on the board, and a bullet that has a firing rod at its tip that is pivoted on the board. The firing part is urged to face the ball firing position, the outlet of the ball supply gutter is made to face the ball receiving groove formed in the operating cam, and the ball guided by the ball feeding gutter is placed into the ball receiving groove of the operating cam. It is possible to take in one ball and supply it as a shot ball to a ball shooting position by rotating the operating cam, and a ball moving force receiving part formed integrally with the shooting rod faces the operating cam,
A pachinko machine configured such that the firing rod is elastically rotated by the balls that are taken into the ball receiving groove and transferred, and the ball is launched by the moving force of the balls that are supplied to the ball firing position. The aim is to provide a ball launcher for the machine.

The present invention will be explained below based on drawings of embodiments.

As shown in Fig. 1, the pachinko machine 1 has a game board 2 on the front surface with a loose arc-shaped guide rail 3 on the top, side rails 4 on the left and right sides, and a gently sloping gathering rail 5 on the bottom. It has a substantially quadrilateral enclosed game section 6, and inside the game section 6 are provided numerous obstacle nails (not shown) and prize winning devices 7..., and an out port 8 is provided at the bottom of the game section 6. be.

The guide rail 3 guides the ball so that it can easily fall to the position targeted by the player, and a ball launcher 9 according to the present invention is provided at one end of the guide rail 3.

The ball launch device 9 supplies balls in a ball supply gutter 10 disposed at the upper part of the back side of the game board 2 to a ball launch position 12 by rotating an operating cam 11, and rotates a launch rod 13 to supply the balls as a launch ball to a ball launch position 12. This is to fire the ball at the ball firing position 12.

At the ball firing position 12, the lower end of the plate 15 that is slightly inclined downward toward one side of the substrate 14 is raised up, and the raised part is further folded back laterally to form a U-shaped cross section. Through hole 16 smaller than the ball diameter
Established. And ball receiving grooves 17, 1 on the outer peripheral surface.
The actuating cam 11 formed with 7 is moved to the ball firing position 12.
A rotary drive device 18 is connected to the operating cam 11 so as to rotate the operating cam 11.
An outlet 10' of the supply gutter 10 is opened near the top of the groove 1 to face the ball receiving groove 17. Also, an operating cam 11 extending from the outlet 10' of the ball supply gutter 10 to the ball firing position 12
A semicircular guide frame 19 is provided on one side, a ball passage 20 is formed between the guide frame 19 and the operating cam 11, and a lower end outlet of the ball passage 20 is connected to the ball firing position 12; The upper end of the firing rod 13 is rotatably mounted near the operating cam 11. Then, the moving force receiving portion 22 formed integrally with the firing rod 13 is connected to the operating cam 11.
Let's face it. For example, according to the illustrated embodiment, the arm rod 2 protrudes sideways from the pivoting base end of the firing rod 13.
A ball moving force receiving part 22 formed at the tip of the firing rod 1 is positioned within the ball passage 20 and faces the outer peripheral surface of the actuating cam 11, and a ball movement force receiving part 22 formed at the tip of the firing rod 13 is positioned in the ball passage 20 and faces the outer peripheral surface of the actuating cam 11. Move the firing section 23 to the ball firing position 12
It is biased by the first spring 24 so as to face. Further, one end of a rope 26 is connected to a projecting piece 25 projecting upward from the base end of the firing rod 13, and a second spring 27 is interposed in the middle of the rope 26, and the other end is used to wind up the firing operation part 28. Wrap it around pulley 29.

Therefore, the operation piece 30 of the firing operation section 28 provided on the front of the pachinko machine 1 is rotated to close the take-up pulley 2.
By adjusting the length of the rope 26 wound around the ball 9, the strength with which the second spring 27 biases the firing rod 13 can be adjusted, and the firing force of the ball can be adjusted to a desired strength.

Further, when the operation piece 30 of the firing operation section 28 is rotated, a pressing piece 31 provided on the winding pulley 29 or the shaft (not shown) of the operation piece 30 acts on the starting switch 32 to operate the take-in device 33. .

The taking-in device 33 intermittently takes in one ball at a time from a supply tray 34 provided at the front of the pachinko machine 1, and operates the ball launcher 9 in response to the balls taken in. The taking-in device 33 shown in FIGS. 4 and 5 is a taking-in device 33 that is rotationally driven by a motor 36 and is installed at an outlet 35' of an introduction gutter 35 through which balls placed in a supply tray 34 by a player are introduced while being aligned in a line. The cam 37 is faced, the lower receiving piece 38a of the bifurcated control rod 38 is taken in and biased by its own weight against the outer peripheral surface of the cam 37, and on the downstream side of the control rod 38 there is an L-shape whose base end is pivoted. Lower end 3 of shaped ball detection rod 39
9a facing the outer peripheral surface of the take-in cam 37, and the lower end 39a is biased by a weight 40 provided on the arm piece 39b.

When the start switch 32 is turned on by rotating the operation piece 30 of the firing operation section 28, a motor 36 electrically connected to the switch 32 starts the intake cam 37 at a predetermined speed, for example, 50 rpm. 4
Rotate in the direction of the arrow in the figure. Grooves 41, 41 are formed on the outer circumferential surface of the intake cam 37 to accommodate one ball,
The depth of the groove portion 41 is made shallower than the diameter of the sphere. Therefore, when the intake cam 37 is rotated, the introduction gutter 35
One ball waiting at the exit 35' of the groove 41
It can be imported intermittently. When the ball enters the groove 41, the top of the ball protrudes from the outer peripheral surface of the take-in cam 37. Therefore, when this ball rotates together with the intake cam 37, the top of the ball touches the control rod 38.
The control rod 38 is rotated from the state shown by the solid line in FIG. 4 to the state shown by the chain line by pressing the receiving piece 38a. When the control rod 38 rotates, the upper engagement piece 38b of the control rod 38 disengages from the engagement protrusion 39c of the ball detection rod 39, releasing the ball detection rod 39 into a rotatable state. When the ball further rotates, the lower end 3 of the ball detection rod 39 is moved while the control rod 38 is supported in an inclined state.
9a is pressed to rotate the ball detection rod 39 from the state shown by the solid line in FIG. 4 to the state shown by the chain line. When the ball rotates further and separates from the receiving piece 38a of the control rod 38, the protrusion 39c of the ball detection rod 39 is positioned below the end of the engaging piece 38b of the control rod 38, causing the control rod 38 to be tilted. support. When the ball rotates further and leaves the lower end 39a of the ball detection rod 39, the ball falls out of the groove 41 due to its own weight and falls into the discharge gutter 42, and is lifted up by the reduction 43 provided on the back side of the Pachinko machine 1. and is supplied to the upper tank 44. If the inner surface of the groove 41 on the rotational direction side is slightly inclined and widened as shown in FIG. 4, the ball will easily come out of the groove 41. Also the control rod 38
If the ball detection rod 39 can be locked as described above, it is effective to prevent fraudulent acts.

When the ball detection rod 39 rotates due to the pressure of the ball, the detector 45 provided facing the arm 39b of the ball detection rod 39 is turned on, and the pulse motor 18' of the rotary drive device 18 is rotated at a predetermined rotation speed. That is, in order to perform the firing operation of the firing rod 13 only once, the firing rod 13 is rotated by just the right number of revolutions.

In order to perform a firing operation of the firing rod 13 by driving the rotary drive device 18 each time the taking-in device 33 takes in one ball from the supply tray 34, for example, the seventh
As shown in the figure, the detector 45 and the pulse motor 1
8', a rotation control circuit 48 consisting of a pulse oscillator 46, a ring counter 47, etc. may be interposed and electrically connected.

In FIG. 7, when the detector 45 is turned on, a signal is sent to the set side of the flip-flop 49 to set the flip-flop 49, and the flip-flop 49 is connected to one input side of the AND gate 50.
A signal is sent from Therefore, the AND gate 50 has the pulse oscillator 4 connected to the other input side.
6 and sends a clock pulse signal to the ring counter 47. When the ring counter 47 receives the clock pulse signal from the AND gate 50, it operates the pulse motor 18' via the driver 51 in response to the clock pulse signal, and when it receives a predetermined number of pulse signals, it sends a signal to the reset side of the flip-flop 49. is sent to reset the flip-flop 49. That is, the ring counter 47 rotates the pulse motor 18' by the amount of the pulse signal preset in the ring counter 47, and reliably stops the motor 18' at a predetermined rotation angle.

When the pulse motor 18' rotates by a predetermined angle, it rotates the operating cam 11 by a predetermined angle via the speed reducer 18''. Since two balls are formed, each time the taking-in device 33 takes in one ball from the supply tray 34, that is, each time the detector 45 detects one ball, the pulse motor 18' rotates the actuating cam 11 by half a turn. It is set to rotate.

The operating cam 11 takes one ball from the ball supply gutter 10 into the ball receiving groove 17 located above, and starts rotating with the top of the ball protruding from the outer peripheral surface of the cam 11. When the ball rotates in the ball passage 20 together with the operating cam 11 in this state, the top of the ball presses the ball movement force receiving part 22 of the firing rod 13 and the firing rod 1
3 is rotated from the state shown by the solid line in FIG. 2 to the state shown by the chain line. When the firing rod 13 is sufficiently rotated and the ball leaves the ball moving force receiving section 22, the firing rod 13 is suddenly rotated back due to the bias of the springs 24 and 27, and the firing section 23 is placed at the ball firing position. 12 and fires the ball at the firing position 12. The fired ball flows down inside the game part 6 while hitting an obstacle nail and enters a winning device 7 to become a winning ball, or flows directly to a collection rail 5 and enters an out port 8 to become an out ball.

During the rotation, the actuating cam 11 rotates the firing rod 13 by the moving force of the ball via the ball in the ball receiving groove 17 and performs a firing operation, and then rotates further and moves the ball into the ball receiving groove 1.
7 is located below, the ball in the ball receiving groove 17 is supplied to the ball firing position 12 and stopped. Note that when the actuating cam 11 rotates half a turn to fire the ball and supply the ball, the ball receiving groove 17, which was located at the bottom and stopped, moves to the top and stops, and then the ball is supplied. The balls are received into the ball receiving groove 17 from the outlet 10' of the ball supply gutter 10 and are kept on standby. Then, when the detector 45 of the taking-in device 33 detects the next ball and turns ON, as shown in FIG.
8' again by a predetermined angle. Therefore, the operating cam 11 continues to rotate half a rotation, and the firing rod 13 is rotated in the same manner as described above to fire the previously supplied ball and to supply the next ball to be fired to the ball firing position 12. . Note that the drive source of the drive device 18 is not limited to a pulse motor, and may have any configuration as long as it can control rotation at a preset angle.

As described above, when the player operates the firing operation section 28 to activate the capturing device 33 to capture one ball supplied to the supply tray 34, each time the detector 45 detects one captured ball. The actuating cam 11 is then rotated to fire the ball and the ball to be fired next can be supplied to the ball firing position 12. The ball firing and ball feeding operations can be continued while balls continue to be taken in from the supply tray 34 intermittently.

Note that if there is a shortage of balls in the ball supply gutter 10, a so-called dry hitting phenomenon occurs in which the ball is not ejected even if the take-in device 33 is activated to take in a ball from the supply tray 34 and the ball launcher 9 is activated. Therefore, in order to prevent the above-mentioned dry firing phenomenon, the ball shortage detector 52 is placed facing the ball supply gutter 10, and the detector 52
is connected in series with the activation switch 32 of the operating section 28, as shown in FIG. If you do it like this,
There is a ball in the supply gutter 10, and the operating part 28
When the starting switch 32 is turned ON by operating the button, the taking-in device 33 is operated by the motor 36 to take in balls from the supply tray 34. When the take-in device 33 takes in a ball, the detector 45 detects the ball, so the ball launcher 9 operates to fire the ball and can supply the ball to the ball launch position 12. On the other hand, if there is a shortage of balls in the ball supply gutter 10,
Since the ball shortage detector 52 acts to cut off the electrical connection to the motor 36, even if the player operates the firing operation section 28 and turns on the starting switch 32, the taking-in device 33 does not operate. Therefore, if there is a shortage of balls in the supply gutter 10, the balls in the supply tray 34 will not be taken in, and the player will not be disadvantaged.

In order to supply balls to the ball supply gutter 10, the upstream entrance of the ball feed gutter 10 may be connected to the upper tank 44 that stores balls to be ejected as prizes, or the upper tank of each pachinko machine 1 may be 44 may be routed directly from a replenishment trough (not shown) that replenishes balls. In addition, on the back side of the game board 2, a collecting gutter for collecting winning balls and an out ball gutter for collecting out balls are provided, and the outlets of both gutter are connected to the entrance of the ball lifting device, and the inlet of the supply gutter is connected to the ball lifting device. Even if the ball connected to the outlet of the feeding device is collected by the collecting gutter and the out ball gutter, the balls collected by the collecting gutter and the out ball gutter are lifted by the lifting device and returned to the supply gutter, and a certain number of balls previously sealed in the pachinko machine 1 are used for circulation. good. If the balls used in the game are circulated in this way, a card reading device is provided instead of the loading device 33,
A recording medium that records the number of balls played, player number, etc.
For example, a player inserts a magnetic card into the reading device, the reading device reads the number of game balls, etc., and in response to the process of subtracting the number of game balls by one address, the ball launcher 9 is activated to send out the enclosed balls. It is also possible to fire one at a time.

FIG. 9 shows another embodiment of the ball launcher 9, in which recessed ball receiving grooves 17, 17 are formed on one surface of the disc-shaped operating cam 11 at symmetrical positions centering on the shaft 11'. , the ball moving force receiving portion 22 of the firing rod 13 faces the locus along which the ball receiving grooves 17, 17 pass, and the rotation drive device 18 is connected to the operating cam 11. When the rotary drive device 18 rotates the operating cam 11, the ball waiting at the outlet 10' of the ball supply gutter 10 enters the upper ball receiving groove 17 from the side, and one side of the ball is transferred to the operating cam. It rotates while protruding into the ball passage 20 from the surface of the ball 11. When the ball moves due to the rotation of the operating cam 11, the portion protruding into the ball passage 20 presses the ball movement force receiving portion 22 of the firing rod 13, rotating the firing rod 13 to the state shown by the chain line in FIG. As in the embodiment, the ball at the ball firing position 12 is fired. The ball that has rotated the firing rod 13 is transferred to the ball movement force receiving part 2
2, rotates further and descends to the lowest position, it comes out of the ball receiving groove 17 and reaches the ball firing position 12.
supplied to

In this way, the operating cam 11 may have any configuration as long as it can take one ball from the ball supply gutter 10 into the ball receiving groove 17 and transfer it. Further, the firing rod 13 rotates in response to the force of the ball moved by the operating cam 11, and when it returns and rotates due to the bias of the springs 24 and 27, it fires the ball at the ball firing position 12. Any configuration is acceptable if possible. Furthermore,
The rotation drive device 18 may have any configuration as long as it can rotate the actuating cam 11. For example, the first
As shown in FIG. 0, it may be a machine that is connected by mechanical means to the capture device 33 and rotates the actuating cam 11 when the capture device 33 captures a ball in the supply tray 34. Capturing device 3 shown in FIG.
3 is an introduction gutter 35 that guides the balls in the supply tray 34 in a line;
A driving cam 54 having ball-taking grooves 53, 53 and a driven cam 56 having ball-taking grooves 55, 55 are placed coaxially at the outlet 35' of the cam 54, 56 in a state where each cam 54, 56 can rotate separately. The driving cam 54 is connected to the motor 36, a sprocket 57 is attached to the driven cam 56, and the sprocket 57 and the sprocket 58 of the operating cam 11 are connected by a ladder chain 59. Note that the driven cam 56 is biased by a braking cam 60 provided integrally with a braking rod 62 having a protrusion 61 that engages with a groove 60' of the braking cam 60, so that the ball intake groove 55 is moved into the introduction gutter. 35, and stop facing the exit 35'.

When the player turns on the start switch 32 by operating the firing operation section 28, the switch 3
A motor 36 electrically connected to the drive cam 54 is operated to rotate the drive cam 54. When the driving cam 54 rotates and the ball intake groove 53 of the cam 54 is located at the outlet 35' of the introduction gutter 35 and overlaps with the ball intake groove 55 of the driven cam 56, the ball is waiting at the outlet 35'. The ball enters the ball receiving grooves 53 and 55 of both cams 54 and 56. When the driving cam 54 continues to rotate in this state, the driven cam 56 rotates and rotates the operating cam 11 of the ball launcher 9 via the chain 59. When the operating cam 11 rotates, the outlet 1 of the ball supply gutter 10
One ball is taken into the ball receiving groove 17 from 0' and rotated, and as the ball moves, the firing rod 13 is rotated to fire the ball at the firing position 12. The balls that have entered the ball intake grooves 53 and 55 of both cams 54 and 56 of the intake device 33 move to the vicinity of the discharge gutter 42, are pushed out by the protrusion 64 of the guide piece 63, and are pushed into the ball intake grooves 53 and 55. When the actuating cam 11 comes off and falls into the discharge gutter 42, the operating cam 11 rotates approximately half a turn, and the ball receiving groove 1
The balls in 7 are supplied to a ball firing position 12 as a fired ball.

In this way, the ball launcher 9 shown in FIG.
Each time the taking-in device 33 takes in one ball from the supply tray 34 intermittently, the operating cam 11 is rotated 180 degrees,
The balls in the supply gutter 10 can be supplied one by one to the firing position 12, and the previously supplied balls can be fired.

Note that the operating cam 11 may be a combination of two cams stacked one on top of the other, similar to the above-mentioned intake device 33. In this case, the ball moving force receiving portion 22 of the firing rod 13 is placed within the gap between both cams. In any case, the firing rod 13 is rotated by the movement of the balls supplied from the ball supply gutter 10 to the ball firing position 12, but the means for rotating the firing rod 13 is as described in the above embodiment. In addition, the movement force of the ball may be applied directly to the ball movement force receiving portion 22 of the firing rod 13 by contact with the spherical surface to rotate the ball, or alternatively, the movement force of the ball may be caused to rotate by directly acting on the ball movement force receiving portion 22 of the firing rod 13. The projecting portion forms a ball movement force receiving portion 2 of the firing rod 13.
2 may be pressed indirectly. In this way, the movement of the firing rod 13 can be moderated, and a stable flight distance can be obtained.

As explained above, according to the present invention, an operating cam that is rotatably driven by a drive device is provided above the ball firing position formed on the board, and a ball is formed with a firing rod at the tip that is pivoted on the board. The firing part is urged to face the ball firing position, the outlet of the ball supply gutter is made to face the ball receiving groove formed in the operating cam, and the ball guided by the ball feeding gutter is placed into the ball receiving groove of the operating cam. It is possible to take in one ball and supply it as a shot ball to the ball firing position by rotating the operating cam, and since the ball moving force receiving part formed integrally with the firing rod faces the operating cam, the operating cam can be rotated. By doing so, one ball can be supplied from the ball supply gutter to the target ball firing position, and the ball can be fired by the firing rod which is pivoted and rotated by the moving force of the transported ball.

The ball launcher according to the present invention performs the launch operation by rotating the launch rod using the moving force of the ball supplied to the launch position, so that the player no longer holds any balls and there are no balls in the ball supply gutter. When the ball is fired, the firing rod can be stopped from rotating, and unlike conventional firing devices, the firing rod can rotate and perform the firing operation even if there is no ball at the firing position (so-called ``color''). hit)
can be completely prevented.

Furthermore, since the structure of the firing device itself is extremely simple, it can be miniaturized and requires less space for mounting on the pachinko machine, so there is no restriction on the mounting location and it can be installed at any location. Therefore, if it is installed on one side above the game board,
The surface of the game board can be used more widely as a game part than before, and by arranging a large number of winning devices and large winning devices, it is possible to further enhance the interest of pachinko games.

The ball firing device according to the present invention is not only installed on the upper side of the game board, but also installed on the lower side of the game board as in the past, and can be used to place one ball in the supply tray at the target ball firing position. It can also be used in a pachinko machine that supplies balls and shoots them to play a game.
