DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having a ball feeding operation for supplying a ball to be used for a game to a firing position and a firing control means for controlling a series of operations for firing the supplied ball. Things.

[0002]

2. Description of the Related Art In recent years, pachinko machines using a solenoid as a driving source of a ball feeder and a hit ball launcher have been actively developed by the present applicant and others. It is necessary to electrically detect the sphere supplied to the firing position for timing. In this type of conventional pachinko machine, a configuration is generally employed in which a sphere detection sensor is disposed above a firing rail and the presence of a sphere is detected by the sphere detection sensor.

[0003]

However, in a conventional pachinko machine in which a ball detection sensor is disposed above the firing rail, when a foul ball is generated and returns to the firing rail side, the foul ball is removed. The inconvenience that the detection sensor detects again as a shooting ball (that is, a miss detection) occurs to a considerable extent. Further, since the conventional ball detection sensor has a structure for detecting a ball on a narrow firing rail, high accuracy is required for adjusting the mounting position. Therefore, the assembling work is troublesome. Further, if the player turns off the switch of the firing operation section immediately after the operation of the ball feeder, the ball remains on the firing rail, which is disadvantageous for the player.

[0004]

In view of the above, the present invention has been proposed in view of the above, and a ball to be provided for a game by actuation of a ball feeding drive source (for example, an electromagnet 35) is directed to a single firing position (15). , A ball counting sensor (27) for detecting the balls sent out by the ball feeding device, and a driving source (for example, the rotary solenoid 12) for firing the balls supplied to the firing position. And a launch operation detecting section (16) having a launch operation detecting section (for example, a launch switch 20) for sending out a launch operation signal for operating the hit ball launch apparatus when operated by a player. When the ball feed drive source for receiving the ball feeder firing operation signal from the firing operation detection unit of the ball striking ball firing operation unit
Actuated, receives the ball supply signal from the sphere counting sensor origination
A firing control unit (for example, the firing control device 2) that performs a series of controls for operating the firing drive source regardless of the stop of the firing operation signal.
1).

[0005]

When the player operates the hit ball firing operation section and a firing operation signal is sent from the firing operation detecting section to the firing control means, the firing control means operates the ball feeding drive source for a predetermined time.
Then, when the ball counting sensor detects the ball sent by the operation of the ball feeding device and sends a signal to the firing control means, the firing control means operates the firing drive source even if the player stops the firing operation. , Fire the ball sent to the firing rail.

Are provided, and a frame board 8 is provided at a lower portion of the game board storage frame fixed to the back side of the front frame 3, and the game board 9 is mounted on the frame board 8 and the window board is closed from the back side. A firing rail 10 is attached to the front surface of the frame board 8 and a foul ball collecting gutter 11 is provided. A hitting and firing device 13 driven by a rotary solenoid 12 is provided at a lower rear portion of the front frame 3. An output shaft of the rotary solenoid 12 is provided. The firing portion 14 'of the firing rod 14 having the base end fixed to the firing rail 10 faces the firing position 15 at the base end.

At the right end of the front side of the front frame 3, a hit ball launching operation unit 16 is provided. The hit ball launch operation section 16 is operated by a player by touching the surface of the handle 17 as a conductor by means such as plating or vapor deposition and electrically connecting the conductor to a touch detection device 18 (touch sensor). It is configured to be able to detect the state in which it is running. Further, in this embodiment, a human body detecting device 1 using infrared rays or the like is used.
9, the presence of the player in front of the pachinko machine 1 can be detected. Therefore, when the player who has selected the pachinko machine 1 sits in front of the pachinko machine 1, the above-mentioned human body detection device 19 sends a signal to the control device, and the player
, The touch detection device 18 sends a signal. When the player operates the firing switch 20 as a firing operation detecting unit of the hit ball firing operating unit 16, the firing control device 21 as a firing control unit that receives a firing operation signal from the firing switch 20 includes a human body detecting device. 19 and touch detection device 18
The ball feeding device 7 and the hit ball launching device 13 are operated on condition that a signal has arrived from.

The ball feeder 7 is provided in a unit case 22 attached to the back side of the opening / closing panel 4. The ball feeding device 7 transfers the ball introduced from the ball supply tray 6 through the ball passage opening of the opening / closing panel 4 to the firing position of the firing rail 10. 15 to one.

The unit case 22 includes a case body 22a.
As shown in FIG. 5, a side surface 22c is formed on the side surface of the case body 22a to cover the upper side of the firing rail 10 from the side with the open / close panel 4 closed as shown in FIG. The opening / closing cover 22b is provided with a ball supply port 23 for sending the ball toward the firing rail 10 and a passage port 25 through which the ball passes when the ball in the ball supply tray 6 is dropped into the lower plate 24.

A holder 26 is formed integrally with the opening / closing cover 22b on the front side of the opening / closing cover 22b in which the ball supply port 23 is opened, that is, on the firing rail 10 side. The ball counting sensor 27 is mounted, and the ball passing through the ball supply port 23 can be electrically detected by the ball counting sensor 27.

The sphere counting sensor 27 may be of any configuration as long as it can detect a sphere and send out a sphere supply signal. In this embodiment, a downward U-shaped photo sensor having a sphere passing space 28 is used. You are using

In the present embodiment, the ball counting sensor 27 is formed in a U-shape, so that the holder 26 is formed as an open top frame capable of storing the ball counting sensor 27 and has a bottom portion extending from the lower edge of the opening of the ball supply port 23. Side surfaces 29, 29 are formed on both sides of each side surface, and protective surface portions 3 which also function as locking pieces on the side edges of each side surface portion 29.
0, and a locking projection 31 is formed on the upper inside of each side surface portion 29. Note that the width of the side portions 29, 29 is set slightly larger than the thickness of the ball counting sensor 27, and the height from the bottom portion to the locking projection 31 is set slightly larger than the vertical length of the ball counting sensor 27.

To attach the ball counting sensor 27 to the holder 26 having such a configuration, as shown in FIG. 5, the ball counting sensor 27 is attached to the holder 2 with the opening thereof facing downward.
6, the ball counting sensor 27 is lowered in this state, and the ball counting sensor 27 is loaded into the side surfaces 29, 29 of the holder 26 from the lower end. When the ball counting sensor 27 is sufficiently lowered, the ball counting sensor 27 fits into the storage space surrounded by the bottom surface, both side surfaces 29, 29 and the protection surfaces 30, 30, and the locking projections 31, 31 are moved to the ball counting sensor. 27, and the protection surfaces 30, 30 are locked to and cover the surface of the ball counting sensor 27 on the side of the firing rail 10. Therefore, the ball counting sensor 27 has the upper surface portion and the ball passing space 2
Except for 8, most parts are protected by being covered by the holder 26. For this reason, it does not come off from the holder 26 even if it receives a vibration or a shock.
There is no direct hit by a launch or foul ball.

When the ball counting sensor 27 is mounted on the holder 26 in this manner, the ball supply port 23 communicates with the ball passing space 28 of the ball counting sensor 27. Therefore, when the ball passes through the ball passage opening 28 of the ball counting sensor 27 after passing through the ball supply port 23, the ball acts on the ball counting sensor 27 at this time, whereby the ball counting sensor 27 sends out a ball supply signal. . If the ball counting sensor 27 is mounted in a state where the ball passage space 28 is communicated with the ball supply port 23, the ball can be reliably detected. Therefore, a high precision is required for the mounting to the holder 26. Never. Also, holder 2
The mounting work is also simple because it is merely fitted into the mounting member 6.

As shown in FIGS. 6 and 7, the case body 22a to which the opening / closing cover 22b having the above-mentioned ball counting sensor 27 is attached has a ball entrance 32 communicating with the ball passage opening on the front side. Ball inlet channel 33 from ball inlet 32
Is formed inside. In the embodiment shown in the drawings, the bottom of the ball intake passage 33 is integrally formed with the open / close cover 22b, and the ball intake passage 33 is formed when the open / close cover 22b is closed. In addition, a ball shutter is provided at the bottom of the inclined lower end of the ball intake channel 33. Then, a ball feeding member 34 is provided so as to face the inclined lower end of the ball intake passage 33, and an electromagnet 35 is attached above the ball feeding member 34 as an electric driving source for ball feeding.

The ball feed member 34 has its rear end axially attached to the main body 22 side of the unit case 22 by a shaft 36,
A ball restraining portion 37 is formed on the upper end of the front end facing the inclined lower end of No. 3, and a ball placing portion 38 is formed at the lower end, and an empty space surrounded by the ball restraining portion 37 and the ball placing portion 38 or the like corresponds to one ball. Ball storage space 39
There is. Then, a downward U-shaped iron plate 40 is placed over and fixed to the upper portion of the ball feed member 34. When a plunger-type solenoid or the like is used as the ball-feeding electric drive source, the driving force of the solenoid may be transmitted to the ball-feeding member 34 via a link mechanism or the like.

In order to regulate the operating range of the ball feeding member 34, in this embodiment, the ball feeding member 34 swings up and down at the front end portion about the shaft 36 at the rear end.
A receiving plate 41 is provided below the tip of the ball feed member 34, and an impact absorbing member 42 made of an elastic material such as rubber is fixed above the tip of the ball feed member 34.

Therefore, the ball feed member 34 always descends by its own weight and stops in the first state (FIG. 6) supported by the receiving plate 41, and receives an electromagnet 35 by a ball supply signal from the firing control device 21. Is excited for a predetermined time and is pulled up by the magnetic force at this time, the upper end of the ball suppressing portion 37 comes into contact with the shock absorbing member 42 (second state) and stops (FIG. 7).
The operating range is regulated by the receiving plate 41 and the shock absorbing member 42.

In the receiving plate 41, the ball in the ball storage space 39 of the ball feed member 34 rolls due to the inclination of the upper surface of the ball storage space 39, and the ball supply port 23 opened in the opening / closing cover 22b. And the ball restraining portion 37 is arranged at a height at which the ball restraining portion 37 abuts on the earliest ball in the ball intake channel 33 to prevent the ball from flowing down in the ball intake channel 33. . Also,
In the shock absorbing member 42, the ball restraining portion 37 of the ball feeding member 34 is disengaged from the earliest ball in the ball intake channel 33, and the earliest ball rolls and enters the ball storage space 39, Moreover, the iron plate 40 is arranged at a height where a slight gap is formed between the iron plate 40 and the iron core without abutting on the iron core of the electromagnet 35. Further, the electromagnet 35 is provided with a coil provided on a downward U-shaped iron core, and the tip of the iron core is made to face the iron plate 40 of the ball feed member 34.

When playing a game in the pachinko machine 1 provided with the ball feeder 7 having the above-described configuration, when a player throws balls into the ball supply tray 6, these balls are flown down the ball alignment path. They are arranged in a line, and are introduced into the ball intake channel 33 from the ball passage of the opening / closing panel 4 through the ball inlet 32 of the unit case 22. When the player does not operate the firing operation unit 16, the firing switch 20 and the touch detection device 18
Is off, the electromagnet 35 remains demagnetized, and the ball feed member 34 descends at its tip and the first
It is stopped in a state (FIG. 6). Therefore, the ball introduced into the ball intake flow path 33 waits in a state where the earliest ball is in contact with the ball restraining portion 37 of the ball feeding member 34 and is prevented from flowing down.

When the player presses the firing switch 20 while holding the firing handle 17, the firing switch 20 is turned on and sends a firing operation signal to the firing control device 21. Glass frame 5
When the open / close panel 4 is normally closed and a closed state signal is sent from the metal frame switch and the panel switch to the firing control device 21, the firing control device 21 The power is intermittently supplied to the electromagnet 35 for a predetermined time to excite the electromagnet 35. When the electromagnet 35 is excited, the iron plate 40 of the ball feed member 34 is attracted upward by the magnetic force of the tip of the iron core, and the ball feed member 34
6, the tip is rotated in the upward direction (counterclockwise in FIG. 6). And the rotated ball feed member 34 is
The ball suppressor 37 at the upper end of the tip comes into contact with the shock absorbing member 42 (second state) and stops (FIG. 7).

When the ball feed member 34 is changed to the second state,
Since the ball restraining portion 37 of the ball feeding member 34 comes off the foremost ball of the ball intake channel 33, the ball rolls and the ball feeding member 34
Into the ball storage space 39, and the next ball is the ball storage space 3
9 is prevented from flowing down by the ball that has entered the
Stop at the falling tip of. Since the ball stored in the ball storage space 39 is located higher than the upper opening edge of the ball supply port 23 of the opening / closing cover 22b, the ball is suppressed by this upper opening edge, and It does not flow down.

When the electromagnet 35 is demagnetized after a lapse of a predetermined time, the ball feed member 34 returns to the direction of descending the tip with the weight of the ball and rotates about the axis at the rear end as a center. Ball feed member 3
When the ball 4 returns and rotates, the ball in the ball storage space 39 also descends, so that the ball comes off the foremost ball of the ball intake flow path 33. Ball contact portion 37 contacts the earliest ball. Therefore, the ball at the earliest position in the ball intake flow path 33 is blocked by the ball restraining section 37 and stands by. Further, when the ball feed member 34 returns and rotates and descends its tip, the ball in the ball storage space 39 also descends and comes off the upper opening edge of the ball supply port 23. Therefore, the ball in the ball storage space 39 rolls due to the inclination of the bottom surface of the ball storage space 39 and is sent out of the unit case 22 from the ball supply port 23, and when the ball passes through the ball supply port 23. The ball counting sensor 27 that has detected the ball sends a ball detection signal to the launch control device 21. Then, the sphere acting on the ball counting sensor 27 falls on the firing rail 10 and the firing rail 1
It rolls by the downward inclination of 0 and is supplied to the firing position 15, where it temporarily stops.

When a ball is supplied to the firing position 15, the rotary solenoid 12 of the hit ball firing device 13 is operated by a signal from the firing control device 21 to rotate the firing rod 14 from the standby position to the firing position 15. . Therefore, the ball supplied to the firing position 15 is repelled by the repelling portion 14 ′ of the firing rod 14, jumps from the firing rail 10 into the game area 44 via the guide rail 43, and is used for a game. .

In the present invention, even if the player stops the firing operation immediately after the ball feeding device 7 supplies the ball, for example, the single operation switch 45 provided in the firing operation section 16 or the vicinity thereof is operated. Only the ball supplied under the control of the launch control device 21 described later is reliably fired and does not leave the ball on the launch rail 10. If the firing operation is stopped even after a predetermined time has elapsed since the ball counting sensor 27 detects the ball, the firing control device 21 outputs a firing stop signal at this time to perform the ball feeding and firing operation. Stop. In addition, until the firing stop signal is output, the hitting of the hit ball is processed as valid, but after the firing stop signal is output, even if the winning signal is sent to the accessory control device 46, an improper act is performed. Since it can be predicted that the winning signal has occurred, the winning signal is processed as invalid.

If the ball counting sensor 27 does not detect a ball within a predetermined time after the operation of the ball feeder 7, it is determined that a ball is missing or jammed. A trouble signal is sent to the management device 48 in the central control room by sending a generated signal and blinking or illuminating the trouble indicator 47 for visual display, generating a warning sound by a buzzer or the like, and simultaneously sending a trouble signal to the management device 48 in the central control room. Notify occurrence.

When the ball supplied to the firing position 15 is fired without such a trouble, the rotary solenoid 12 is demagnetized and returns and starts to return to the standby position. , The electromagnet 35 is excited again, and the next sphere is supplied to the firing position 15 in the same manner as described above. Thus, the ball feeder 7
In response to a signal from the firing control device 21, the ball is repeatedly addressed to one ball in synchronization with the firing operation of the hit ball firing device 13 (while maintaining a predetermined time difference in the excitation timing of the electromagnet 35 and the rotary solenoid 12). Supply to launch position 15. Then, the ball counting sensor 27 moves the ball supplied to the firing position 15 through the ball supply port 23 by the operation of the ball feeder 7 into the ball passage space 28, that is, exits the ball supply port 23. At the point of time, the ball detection signal
1 and the hit ball launching device 13 operates in response to a signal from the ball counting sensor 27.

If the hit ball is returned to the firing rail 10 as a foul ball, the ball counting sensor 27 does not detect the ball on the firing rail 10. The supply signal is not sent to the launch control device 21. Therefore, there is no inconvenience that the hit ball firing device 13 operates based on the detection of a missed ball.

The ball counting sensor 27 of the present invention
May be any type of detector as long as it has a function of detecting a sphere supplied from the sphere supply port 23 and transmitting a signal. The holder 26 holding the ball counting sensor 27 may have any configuration as long as it can hold the ball counting sensor 27 in a state facing the ball supply port 23. For example, a configuration is also possible in which a plurality of claws project from the opening / closing cover 22b, and the ball counting sensor 27 is held outside the ball supply port 23 by these claws.

Next, the ball feeder 7 and the hit ball launcher 13
Will be described. The launch control device 21 is configured by, for example, a microcomputer, and is connected to the electromagnet 35 of the ball feed device 7 and the rotary solenoid 12 of the hit ball launch device 13 via a driver 51 as shown in FIG. The ball counting sensor 27 of the ball feeding device 7, the human body detection device 19, and the touch detection device 1 of the hit ball firing operation unit 16 via the filter 52.
8, connected to the single shot switch 45, the firing switch 20, etc., and further connected to the accessory control device 46 for controlling the prize tool, the discharge control device 53 for controlling the ball discharge device, and the management device 48 of the central control room. I have.

The firing control device 21 performs a firing condition determination process, a ball feeding process, a firing start process, and a firing process as shown in the flowchart of FIG. As shown in the flowchart of FIG. 11, the firing condition determination process includes turning on / off the human body detection sensor (human body detection device 19), turning on / off the touch sensor (touch detection device 18), and turning on / off the single shot switch 45. If it is determined that the human body detection sensor and the touch sensor are ON and the single-shot switch 45 is OFF, the ball feeding solenoid (electromagnet 35) is excited, a ball feeding timer is set, and thereafter, the process proceeds to a ball feeding process. In addition,
A predetermined time, for example, 80 ms is set in the ball feeding timer.

In the ball feeding process, as shown in the flowchart of FIG. 12, the ball feeding timer is updated, and a timeout of this predetermined time (80 ms) is determined. When the timeout of the predetermined time is determined, the ball feeding solenoid (electromagnet 35) is demagnetized. Ball feed solenoid (electromagnet 3
When 5) is demagnetized, as described above, the ball feeding member 34 swings in the direction of descending the tip to perform the ball feeding operation of sending out the ball in the ball storage space 39. And ball feed electromagnet 3
When 5 (electromagnet 35) is turned off, a firing start timer is set, and then the process proceeds to firing start processing. The firing start timer is a timer for starting the hit ball firing device 13 at a point in time when a predetermined time has elapsed after performing the ball feeding operation, and for setting a timing of sending the ball and firing the hit ball, for example, set to 444 ms. I do.

In the firing start process, as shown in the flowchart of FIG. 13, it is determined whether the ball counting sensor 27 is ON.
When the ball counting sensor 27 is OFF, the firing start timer is updated, and then the predetermined time (444 ms) of the timer is updated.
The above operation is repeated when no timeout occurs, and when the timeout occurs, the counting sensor detection flag is determined to be ON. In this state, the counting sensor 27 is not turned on, that is, the ball feeding member 34.
Since the ball has not actually passed the firing rail 10 even after the predetermined time set in the firing start timer has passed despite the operation of sending the ball, the trouble display provided on the pachinko machine 1 By turning on or blinking the lamp 47, the absence of a ball and the ball clogging are displayed. Since the count sensor detection flag is not set when the count sensor 27 is OFF, the determination of the count sensor detection flag does not become YES in this state.

On the other hand, when the counting sensor 27 is turned on,
That is, when the ball feeder 7 is operated to detect a ball sent to the firing rail 10 side, an effective timer is set, a ball counting sensor detection flag is set, a firing start timer is updated, and a timeout of this timer is determined. . If no timeout occurs, the above operation is repeated. However, when a predetermined time (444 ms) elapses and the timeout occurs, it is determined that the counting sensor detection flag is ON. In this state, since the counting sensor detection flag is set, no ball is displayed and no clogging is displayed. Therefore, it is determined as YES here. The control enters the rotary solenoid 12 of the firing device 13), sets a firing timer, and shifts to firing processing.

In the firing process, as shown in the flowchart of FIG. 14, the firing timer is updated and then the timeout of the timer is determined. The firing timer sets the drive time of the electric drive source of the hit ball firing device 13, and in the present embodiment, is set so as to excite the rotary solenoid 12 for a predetermined time (80 ms). Therefore, until the predetermined time elapses, the rotary solenoid 12
Is excited to rotate the firing rod 14 from the standby position toward the firing position 15 to fire the ball at the firing position 15 as described above. Then, when a predetermined time of the firing timer elapses and a timeout is determined, the firing is stopped, that is, the rotary solenoid 12 is demagnetized, and then the process returns to the firing condition determination processing. When the rotary solenoid 12 is demagnetized, the firing rod 14 returns from the firing position 15 to the standby position and rotates by the weight of the firing rod 14 or the urging of the return spring, and stands by at the standby position.

When the hit ball is won and a winning signal is sent to the accessory control device 46, the winning signal is regarded as valid if within a predetermined time of the effective timer set in the above-mentioned firing start processing. After processing, the ball discharge device is operated under the control of the discharge control device 53 to discharge a predetermined number of prize balls. When a winning signal is sent to the accessory control device 46 for more than a predetermined time of the valid timer, the winning signal is invalidated by the accessory control device 46 because there is usually no possibility of improper activity. Process as

As described above, the firing control device 21 of the present invention
When the ball-feeding electromagnet 35 is excited to perform the ball-feeding operation, the rotary solenoid 12 of the hit ball firing device 13 is forcibly excited after a predetermined time set in the firing timer, and is sent to the firing rail 10 side. Even if the launch operation of the ball is stopped within the predetermined time, the launch operation is not performed electrically and the ball is not left on the launch rail 10. For example, as shown in the timing chart of FIG. 9, even if the single-shot switch 45 is operated immediately after the ball feed solenoid (electromagnet 35) is excited to send a single-shot signal to the firing control device 21, the single-shot signal is not affected. After the predetermined time has elapsed, the firing solenoid (rotary solenoid 12) is excited to fire the ball sent by the immediately preceding ball feeding operation, and the ball is not left on the firing rail 10.

Further, even if the player releases his / her hand from the firing operation handle 17 and turns off the touch sensor immediately after the ball feeding solenoid (electromagnet 35) is excited to start the ball feeding operation, the timing chart of FIG. As shown in (2), if the counting sensor 27 detects a ball regardless of the OFF state of the touch sensor, the launching solenoid (the rotary solenoid 12) is excited after a predetermined time, and the ball sent out by the immediately preceding ball feeding operation is fired. , Do not leave the ball on the firing rail 10. Then, when the hit ball is fired and a predetermined time of an effective timer set in the firing start processing elapses, a firing stop signal is output and the firing is stopped. When the player touches the firing operation handle 17 again, the touch sensor is turned on, and the above-described ball feeding and hitting ball firing are resumed.

[0039]

As described above, according to the present invention, ball feeding and ball launching can be controlled in series, and the player can detect the launching operation detecting section of the hitting ball launching operating section immediately after the operation of the ball feeder. Even if the player turns off, the launch control means controls the ball feed and the launch of the ball in a series, so that the ball that has already been launched is reliably fired regardless of the player's stopping the launch operation. Therefore, the inconvenience of the ball remaining on the firing rail can be reliably eliminated, and no disadvantage is given to the player. Even if the shot ball becomes a foul ball and returns to the firing rail, the ball counting sensor does not mistakenly detect the foul ball. Also, if a ball counting sensor is provided facing the ball supply port, the ball counting sensor detects only the ball immediately after leaving the ball supply port, so if a foul ball occurs, the foul ball is detected again. No extra counting is done. Therefore, it is possible to accurately correspond the ball sending operation and the shooting operation of the sent ball. Further, since the launching sphere and the returning sphere do not directly hit the ball counting sensor, it is possible to prevent a trouble such as a failure due to the collision of the sphere. Further, since the ball counting sensor is arranged on the opening / closing panel side, the shot ball or foul ball hardly comes into contact with the ball counting sensor. For this reason, the shot ball does not contact the ball counting sensor and does not fly unevenly, and the shot of the ball is stabilized. Furthermore, since the ball counting sensor is disposed on the ball supply port side of the opening and closing panel side, high mounting accuracy is not required, and wiring processing can be performed together with other electric components of the opening and closing panel,
This can improve the efficiency of the assembly work,
By opening the open / close panel, maintenance inspection and cleaning work can be easily performed.
