2. Description of the Related Art In a conventional gaming machine, in particular, a pachinko gaming machine, a predetermined number of prize balls are ejected by a game ball ejecting device on condition that game balls are won in a winning section. Also, when lending out game balls, a predetermined number of loaned balls are discharged by the game ball discharge device in response to a request for lending of game balls by a player. In discharging a predetermined number of game balls in this way, a detector is provided for counting the number of game balls flowing down the game ball discharge gutter, and the number of discharged game balls is counted based on a signal from this detector. A game ball discharging device for discharging a predetermined number of game balls has already been proposed by the present applicant (for example, Japanese Patent Application No. 58-112179, Japanese Patent Application No. 60-250450). In such a game ball discharging device, the detector generates one detection signal (pulse signal) each time one prize ball passes, and the generation of this signal causes one game ball to be discharged. It is determined that the game ball has been ejected and the discharge control of the game ball is performed.

[0003]

However, it has become clear that the following problems can occur in the above-described conventional game ball discharging device when the game balls are discharged. That is, in the discharge path of the game ball, the game ball is continuously discharged, so that the game ball discharged this time collides with the game ball discharged first, or the game ball hits the inner wall of the discharge path. When the game ball collides, the game ball may momentarily bounce in a direction opposite to the downflow direction, or may stop and vibrate (chatter) on the spot.

[0004] When such a ball rebounds or vibrates, the detector may output a pulse signal two or more times when one game ball flows, and the number of game balls actually discharged is reduced. It may happen that the discharge of the game balls is finished before the number of the game balls to be played is reached. As a result, a disadvantage is brought to the player, which may cause a trouble between the player and the game store, which may impair the reliability of both. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a game ball discharging device capable of accurately discharging a desired number of game balls.

FIG. 2 is a front view showing only the prize ball discharging unit 120a constituting the second discharging mechanism 120 of the prize ball discharging unit 100 installed on the back side of the pachinko gaming machine 1. The prize ball discharge unit 120a guides the prize ball sent from the guiding gutter 112 connected to the storage tank 111 to the prize ball discharge gutter 137 side, in which the prize ball discharge gutter 150 is bent. Is provided. The upper, middle, and lower tiers of the prize ball outlet gutter 150 have a decompression path 151, a marginal path 152, and a discharge path 1, respectively.
53.

Of these, the pressure reducing path 151 is connected to the storage tank 11
The moving pressure of the reserve ball (prize ball) sent from 1 through the guiding gutter 112 is reduced, as shown in FIG.
It is formed by making a U-turn in a gentle inclination state at a bent portion (first bent portion) 151a in the middle.

In addition, the marginal path 152 is provided with a space between prize balls passing through the discharge path 153 located below,

On the other hand, a ball clogging prevention projection 152e is provided on the rear wall of the direction change passage portion 152b so as to protrude forward. Due to the ball clogging prevention protrusion 152e, the center position of the lowest prize ball (prize ball on the attenuating inclined portion 152c) B1 of the prize balls stopped vertically in the vertical passage portion 152a is directly above it. It will always be located ahead (left side in FIG. 2) of the center position of the prize ball B2. As a result, the downward moving pressure of the upper prize balls (B2, B3...) Always pushes the lowest prize ball B1 (prize ball on the attenuation slope 152c) in the downward flow direction (left side in the figure), Ball clogging at this position is prevented. More specifically, the center position of the ball B1 pushed forward (to the left in the drawing) by the ball blocking prevention protrusion 152e is at least forward of the center position of the ball B2 immediately above the ball B1. It is located forward by the distance of the protrusion width d (> 0). As a result, the lowest attenuation slope 1 of the prize balls stopped vertically in the vertical passage portion 152a.
The ball (B1) on 52c is pushed downstream by the downward moving pressure of the ball (B2) immediately above it.

A prize ball sensor (discharge sensor) 200 as a detecting means for detecting a prize ball flowing down the discharge path 153 is provided in the discharge path 153 of the prize ball lead-out gutter 150. Further, below the prize ball discharge unit 120a, a prize ball holding device 123 for controlling the flow of the prize ball in the discharge path 153 is installed. The prize ball retaining device 123 is provided with the partition plate 12 of the prize ball discharge unit 120a.
The prize ball discharge solenoid (discharge solenoid) 123a as an electric driving means installed at the lower portion of the prize ball 0b and driven by the driving force of the solenoid 123a to discharge the prize ball in the discharge path 153 of the prize ball discharge gutter 150. Downstream to control
A blocking member 123b is provided.

When the discharge solenoid 123a is demagnetized (off), its own weight and the return spring 1
It has a return rod 23d which is lowered and returned by the return force of 23c and rises when excited (turned on). On the other hand, the downflow prevention member 123b is
Ob is rotatably supported by a support shaft 120c protruding from a lower portion of the support shaft 120b. On one side of the downflow prevention member 123b,
A connecting pin 123e is protrudingly provided, and the connecting pin 123e and a lower end of the operating rod 123d of the discharge solenoid are connected by a connecting plate 123f.

When the discharge solenoid 123a is demagnetized (turned off), the operating rod 123d descends and the distal end of the flow-down preventing member 123b moves to the discharge path 153.
Through the notch 154 provided in the discharge passage 153.
It is designed not to get inside and let the prize balls inside flow down.

On the other hand, when the discharge solenoid 123a is excited (turned on), the operating rod 123d is raised, and the flow-down preventing member 123b is rotated in the direction in which the tip thereof rises, so that the inside of the discharge passage 153c of the prize ball discharge gutter is formed. , And the prize ball held in the discharge path 153c flows down.

As described above, the prize ball discharge unit 12 provided with the prize ball holding device 123, the discharge sensor 200, and the like.
Oa is sealed by a lid frame not shown. The discharge solenoid 123a and the discharge sensor 200 are electrically connected to the prize ball discharge control device 60 (FIG. 1) via connectors (not shown) (see FIG. 9).

Next, the shape of the discharge path 153 that forms the lowermost part of the prize ball outlet gutter 150 will be described in more detail. The discharge path 153 of this embodiment is used for discharging a prize ball.
In order to prevent the prize ball from bouncing at least in the discharge sensor 200 in a direction opposite to the flowing direction or stopping and chattering at that position, the prize ball has the following shape.

That is, as shown in FIG. 2, the discharge path 153 includes three discharge paths having different gutter widths or inner diameters (a first discharge path 153a upstream of the discharge sensor 200 and a discharge sensor 2).
00 and the second stop member 123b of the stopping device.
The discharge passage 153b, the above-mentioned downflow prevention member 123b and the discharge gutter 1
Third discharge path between the 37 153c) Ru Tona.

The first discharge path (detector inflow section) 1
Reference numeral 53a guides a prize ball into the discharge sensor 200. When the discharge solenoid 123a is operated, it is required that one prize ball stored upstream of the discharge solenoid 123a flow smoothly. In addition, the second discharge path (detector outflow section) 15
3b is required to smoothly discharge the prize balls from the discharge sensor 200 (to prevent collision between the prize balls).
The third discharge path (prize ball drop section) is the second discharge section 1
It is required that the prize ball flowing down 53b be quickly discharged to the prize ball discharge gutter 137 (to prevent clogging of the ball).

In order to achieve the required function of each of the discharge paths, the gutter width or the inner diameter of each of the three discharge paths of the present embodiment (the gutter width or the inner diameter A of the first discharge path 153a). , The gutter width or inner diameter B of the second discharge path 153b, and the gutter width or inner diameter C of the third discharge path 153c are A <B, B <
C. By determining the gutter width or the inner diameter in this way, when the prize ball is discharged, the prize ball passes through the first discharge path 153a relatively slowly,
After that, when it has passed through the discharge sensor 200, it flows down the discharge path 153 relatively quickly.
After reaching 3c, it flows down to the discharge gutter 137 more quickly. As described above, the prize ball gradually flows down in the discharge path 153 according to the flow-down position, so that the prize ball that has passed through the discharge sensor 200 this time has already passed through the sensor until immediately before. Therefore, there is no possibility that the sensor 200 will detect one prize ball more than once because the prize ball bounces due to the collision between the prize balls.

By the way, in the prize ball discharging device of this embodiment,
Further, the discharge sensor 2 is used to prevent a problem due to the bouncing of the prize ball (the sensor detects one prize ball twice).
00 is configured in detail below. Hereafter, discharge route 1
The configuration of the prize ball sensor (discharge sensor) 200 installed at 53 will be described in detail.

The discharge sensor 200 is different from the conventional sensor in that it has two detection units (first and second detection units 201 and 202). More specifically, as shown in FIG. 3, the discharge sensor 200 of the present embodiment has a substantially U-shaped casing 2 that is hollow and has an open rear.

As shown in FIGS. 3 and 4, the first arm portion 213 and the second arm portion 214 extend from the front end portion of the opposing surface to the back side, as shown in FIGS. Two flat portions 223 are formed. The first flat portion 222 and the second flat portion 223 are attached to the base 212 from the front end.
The distance between the sphere passing portions 215 until the vicinity of the base 21
The first curved surface 22 gradually narrows as it approaches 2.
4. The second curved surface 225 is formed (FIG. 4), and the third plane portion 226 and the fourth planar portion 226 are located near the end (position in contact with the base 212) where the first curved surface 224 and the second curved surface 225 are at the minimum distance. The flat portions 227 face each other and are formed so as to be substantially parallel to each other. The flat portions 226 and 227 function as a first defense projection 228 and a second defense projection 229 described later.

An E-shaped opening is formed from the tip of the first flat portion 222 of the first arm portion 213 to the first curved surface 224 (FIG. 3), and the first and second openings are formed in the E-shaped opening. 2
An E-shaped translucent member 230 constituting the windows 231a and 231b is fitted (FIG. 3). The translucent member 230 shown in FIG. 3 includes first and second light emitting portions 218a and 218a.
8b through which light emitted by the light emitting elements 220a and 220b passes (the first projection 230a and the second projection 23
0b) is made transparent and the other main body is
Like (6), it is colored (for example, black). Also, the second
The arm portion 214 also has the second curved surface 22 from the second flat portion 223.
5, the E-shaped opening is provided in the same manner as that of the first arm portion 213 (not shown in the figure), and the E-shaped second translucent member 232 is filled in the opening to form the third and third openings.
A fourth window (not shown) is configured. In addition, on the outer side of each end portion of the first arm portion 213 and the second arm portion 214, a vertical groove-shaped locking recess used when attaching the ejection sensor 200 to a winning tool or the like of the ejection path 153 shown in FIG. Parts 236, 2
36 (only one is shown) are formed.

In order to store the first and second light-emitting portions 218a and 218b and the first and second light-receiving portions 219a and 219b in the casing 216 having the above-mentioned structure while being attached to the substrate 217, as shown in FIG. And the light emitting units 218a, 218
18b and the light receiving sections 219a and 219b
The light receiving portions 219a and 219b are provided in the first arm portion 213 in the rear opening portion (not shown in the figure).
The board 217 is joined to the casing 216 in a state where the board 217 is in contact with the rear opening so that the base plates 218 and 218b are inserted into the second arms 214, respectively (FIG. 4). At this time,
The second light receiving sections 219a and 219b are the first and second window sections 2
The first and second light emitting portions 218a and 218b correspond to the third and fourth window portions 233a and 233, respectively, corresponding to 31a and 231b.
b. Note that the substrate 217 is
When the substrate 217 is joined to the rear opening, a filler 237 such as an epoxy resin adhesive is filled from the rear of the substrate 217 to be sealed. Also, the first of the above-mentioned E-shaped,
When fitting the second permeable members 230 and 232 into the openings, the epoxy resin adhesive is similarly applied. In this way, the rear opening of the casing 216 and the first and second openings
When the openings of the arms 213 and 214 are sealed with a resinous adhesive, static electricity is prevented from being transmitted into the casing 216. The first and second light receiving units 219a and 219b and the first and second light emitting units 218a and 218b are
7 is fixed in the casing 216, the first and second light receiving elements 221a and 221b shown in FIG.
Inside the windows 231a and 321b, the first and second light emitting elements 220a and 220b are provided with third and fourth windows 233a and 233, respectively.
The length protruding from the substrate 217 is set so as to be located inside b. The first to fourth windows of the ejection sensor 200 are connected to the bases 21 of the first and second arms 213 and 214.
It is provided at a position closer to two, that is, offset from the center of the sphere, and the intervals between the first and second windows and between the third and fourth windows are extremely narrow. This is because even when the prize balls are continuously released while being in contact with each other, the light-emitting portion 218a to the light-receiving portion 219a via a small space formed between the balls.
This is to ensure that light propagation to the light-emitting unit 218b and light propagation from the light-emitting unit 218b to the light-receiving unit 219b always occur simultaneously. Such characteristics are necessary conditions for a prize ball detection method described later.

The discharge sensor 200 configured as described above
Indicates that the light receiving unit 2 is in a state where no prize ball has passed.
First and second light emitting units 218 provided corresponding to light receiving elements 221a and 221b of 19a and 219b, respectively.
a, 218b of the first and second light emitting elements 220a, 22
It is in a state of receiving light (infrared rays) emitted from Ob.

The first and second light emitting elements 220
Both a and 220b generate pulsed light in synchronization with a pulse signal (for example, a frequency of 10 kHz) of the oscillator 239 shown in FIG. Then, the first and second light receiving elements 221a, 221
Upon receiving this light, the light is converted into an electric signal and sent to the first or second amplifier 240a, 240b. First
Alternatively, the second amplifiers 240a and 240b amplify the electric signal and convert it to the corresponding first or second synchronization detector 24.
1a and 241b. First and second synchronization detectors 24
1a and 241b are the first or second amplifiers 240a and 240a
The AND of the pulse signal from 40b and the pulse signal from oscillator 239 is taken, and the result is sent to first and second demodulation units 242a and 242b, respectively. The first and second demodulation units 242a and 242b are provided with the first or second synchronization detection unit 2
The pulse signals sent from the first and second demodulators 241a and 241b are demodulated to "H level" or "L level" for a certain period. 6 are processed assuming that three consecutive pulses output from the synchronization detectors 241a and 241b are one set, and there are three pulses (t3 to t3 in FIG. 6).
It is determined that the signal is “H level” during the time t4 and that the signal is L level when there are no three pulses (the time between t1 and t2) (only the output of one demodulation unit 242a is shown in FIG. 6).

Therefore, the ball passing portion 21 of the discharge sensor 200
In the case where there is no sphere in 5, light emitted from the first and second light emitting elements 220a and 220b in synchronization with the pulse of the oscillator 239 respectively emits the first and second light receiving elements 221a and 221a.
The signal received by 21b is sent to the first or second amplifier 240a, 240b. Then, the first and second synchronization detectors 241a and 241b take the AND of the amplified signal from the first or second amplifier 240a and 240b and the pulse signal from the oscillator 239. In this case, since the outputs from the first and second amplifiers 240a and 240b are synchronized with the signal from the oscillator 239 (see FIG. 6), they are output from the first and second demodulation units 242a and 242b. The both signals act on the first or second switching transistor 243a, 234b. The switching transistors 243a and 343b are connected to the first or the second
When "H" is output from the demodulation units 242a and 242b, the transistor is turned on, and the current from Vcc flows to the GND side via the switching transistors 243a and 243b. Therefore, the game ball is not located in the ball passage portion 215 (FIG. 3) of the discharge sensor 200, and the light from the first and second light emitting elements 220a and 220b is both the first or second light receiving element 221a and 221b. If you have reached
(OUT1) from the output terminal TOUT1 and the second
The output (OUT2) from the output terminal TOUT2 is at “L level”, and it is detected that the ball has not passed.

On the other hand, the ball passing portion 215 of the discharge sensor 200
When the prize ball passes through the inside, the prize ball is moved from the first and second light emitting elements 220a and 221b to the first and second light receiving elements 2a.
The light emitted to each of 21a and 221b is sequentially blocked with a predetermined time flag. As described above, when the first and second light receiving elements 221a and 221b do not sequentially receive light, as shown in FIG. 6, the pulse outputs from the first and second amplifiers 240a and 240b continue with the time flag. Therefore, the AND condition between the first and second synchronization detectors 241a and 241b and the pulse signal from the oscillator 239 is not satisfied, and the output sequentially becomes "L level". Therefore, the outputs from the first and second demodulation units 242a and 242b are converted to “L level” at the rising of the third pulse, respectively, whereby the first and second switching transistors 243a and 243a are converted.
3b are sequentially turned off, and the current from Vcc sequentially flows to the output terminals TOUT1 and TOUT2. In this way,
TOU when the prize ball is passing through the sensor 200
The outputs of T1 and TOUT2 are sequentially converted to “H level” (the output of the discharge sensor 200 is “H”), and the passage of the prize ball is detected.

Thereafter, when the prize ball passes through the sensor 200, the first and second light receiving elements 221a, 211b
Sequentially receive light from the first and second light emitting elements 220a and 220b, and the first and second switching transistors 243a and 243b are turned on again (current from Vcc flows to GND). As a result, after passing the prize ball, the output of the discharge sensor 200 returns to “L level” again.

In this embodiment, the circuits on the respective detection sections (the first and second light receiving elements 221a and 221b) are:
When a set of three pulses continuously maintain the same level in synchronization with the pulse of the oscillator 239, this is treated as a normal detection signal to determine the presence or absence of a prize ball.
Also, even if the second light receiving elements 221a and 221b receive other light such as external light and the level of the signal changes momentarily, the detection result is not immediately changed and the processing is not performed immediately, so that erroneous detection due to the external light is eliminated. The end of this sphere is the light emitting element 2
20 from the direction other than the normal optical axis (in particular, the base 21
2 direction), this light is emitted from the first and second
Since the protection protrusions 228 and 229 (FIG. 4) block the light, the light does not reach the light receiving element 221. Further, since the base end portion of the ball passage portion 215 of the casing 216 is curved by the first and second curved surfaces 224 and 225 even when used for a long time, dust and the like are unlikely to adhere, and 4
Windows 231a, 231b, 233a, and 233b are not shielded from light by dust or the like.

In the above embodiment, the casing 216 has a substantially U-shape, but the discharge sensor 200 used in the present invention is not limited to this. For example,
The discharge sensor 300 shown in FIGS. 7 and 8 may be used.
This discharge sensor 300 is formed by forming a casing 344 into a thin rectangular box like the conventional proximity type discharge sensor. The first arm 346 and the first arm 346 are formed from both left and right ends of a box-shaped base 345 whose rear surface is opened. A second portion 347 is provided, and a connection portion 348 is provided between the distal ends of the first arm portion 346 and the second arm portion 347.
And a generally rectangular casing 344
Is configured. A first flat portion 349 and a second flat portion 350 (FIG. 8) along the longitudinal direction of the casing 344 are formed on the base 345 side of the first arm portion 346 and the second arm portion 347, respectively. , The connecting portion 34
8, a substantially circular ball passage portion 351 having a gutter width or inner diameter slightly larger than the diameter of the prize ball is formed in a portion surrounded by the first arm portion 346, the second arm portion 347, and the base portion 345. . Alternatively, the sphere passing portion 351 is the first flat portion 34 described above.
9 and both end portions of the second flat portion 350. Further, a first defense projection 352 is formed at a position (projection) where the first plane portion 349 and the ball passage portion 351 are joined, and a position (projection) where the second plane portion 350 and the ball passage portion 351 are joined. Part)
A second defense projection 353 is formed on the first defense projection 35.
The first curved surface 354 and the second curved
A second curved surface 355 is provided in front of the defense projection 353. Then, a translucent member is fitted into the two openings formed in the first curved surface 354, and the first and second windows 356 are formed.
a, 356b, on the other hand, a translucent member is fitted into the two openings formed in the second curved surface 355 to form third and fourth windows 357a, 357b (not shown in the figure). . The first and second light receiving portions 358a and 358b are provided behind the first and second window portions 356a and 356b.
By disposing the first and second light emitting units 359a and 359b behind the fourth windows 357a and 357b, the first and second detecting units 301 and 302 are obtained. In addition, the substrate 360 is inserted through the rear opening of the base 345 and
The filling of a filler 361 such as an epoxy resin adhesive at the rear of the nozzle 60 is the same as the structure of the discharge sensor 200 described above.

Next, a method of counting the number of discharged prize balls using the discharge sensor 200 (or the discharge sensor 300) will be described with reference to FIGS. FIG. 9 shows the excitation (O) of the discharge solenoid 123a (FIG. 2) of the prize ball holding device based on the output signal from the discharge sensor 200 having the above configuration.
FIG. 4 is a block diagram schematically showing a prize ball discharge control device 60 which controls N) / demagnetization (OFF) to discharge a prize ball.

As shown in the drawing, the prize ball discharge control device 60
The prize ball detection unit 61 for detecting the discharge state (the number of discharges, etc.) of the prize ball, and the discharge control unit 62 for controlling the discharge of the prize ball based on the output signal from the prize ball detection unit 61. Separated. The prize ball detection unit 61 includes a ball moving direction determining unit 611 for detecting a flowing direction of a prize ball, a ball moving time determining unit 612 for detecting a flowing time, and a prize ball detection signal output unit 613. In the prize ball discharge control device 60 configured as described above, the output signal of the discharge sensor 200 (the first detection unit 201 and the second detection unit) is transmitted to the ball moving direction determining unit 611 and the ball moving time determining unit 612. Two signals OUT1 and OUT2) from the unit 202 are input.

The ball moving direction determining means 611 determines the direction in which the prize ball flows down according to a method described later using two output signals from the discharge sensor 200, and the prize ball is directed in a direction opposite to the flowing direction. During this time (when the prize ball bounces), the detection signal is invalidated, or a command signal for subtracting the count value of the prize ball is output. On the other hand, the ball moving time determination means 612 measures the speed at which the prize ball flows down using the two output signals OUT1 and OUT2 from the discharge sensor 200, and when the flow speed of the prize ball deviates from a predetermined range. It determines that some abnormality has occurred in the ejection of the prize ball (for example, a state in which the prize ball has rebounded), and outputs a command signal to treat the detection signal from the ejection sensor 200 as invalid. Further, the prize ball detection signal output means 613 includes:
Ball moving direction determining means 611, ball moving time determining means 612
If it is determined that the output signal from the prize is a signal at the time of normal discharge, a signal indicating that one prize ball has been discharged is output to the discharge control unit 62.

The discharge control unit 62 monitors the discharge state of the prize ball based on the signal from the prize ball detection signal output means 613 and further, the signal from the ball moving time determination means 612, and discharges one prize ball. The ON / OFF timing of the discharge solenoid 123a is controlled from the calculated time to execute a desired number of prize ball discharge controls. The input side of the prize ball discharge control device 60 is connected to other detectors such as a ball release switch and an overflow sensor, and the output side is connected to an operating device such as a gate switching solenoid 136b.
These operation controls are also performed.

FIGS. 10 to 23 are timing charts and a prize ball for explaining a procedure for determining the discharge state of a prize ball based on signals from the first detection unit 201 and the second detection unit 202 of the discharge sensor 200. It is an explanatory view showing the operation of. Note that the discharge sensor 200 (3
00), the installation interval of the first and second detectors (the installation interval of the first and second windows shown in FIG. 3) is extremely narrow as described above, so that one prize ball passes therethrough. Before the next prize ball passes, both detectors 201,
Signals OUT1 and OUT2 from 202 become L level.

The timing chart shown in FIG. 10 shows that the prize ball is the discharge path 153 (see FIG.
5) shows the waveforms of the output signals (OUT1, OUT2) from the first detection unit 201 and the second detection unit 202 during normal operation, which are obtained when one of the signals flows smoothly. As shown in the drawing, before the discharge of the prize ball is started, the prize ball is attached to the discharge sensor 200 mounting position, that is, the sensor 2
00, the first detector 201, the second detector
, The output signals OUT1 and OUT2 of the detection unit 202 are both held at the H level (before the time t1).

In this state, when the discharge solenoid 123a is excited and discharge of the prize ball is started, the spherical surface of the prize ball first deviates from the set position of the first detection unit 201. The output OUT1 changes from the H level to the L level (time t1). Further, when the flow of the prize ball proceeds, the spherical surface of the prize ball deviates from the set position of the second detection unit and the output OU is output.
T2 changes to the L level (time t2). As described above, since the interval between the first and second detection units of the discharge sensor 200 is extremely narrow, the first detection unit 201 switches to the next position before the output OUT2 changes to the L level (prior to t2). No prize ball is detected, and the output O of the second detection unit is not detected.
The output OUT1 at the time when the UT2 falls is always at the “L level”.

As described above, one prize ball is output from the discharge sensor 20.
When the value reaches 0 and passes through the second detection unit installation position, the next prize ball is subsequently detected by the first detection unit 201, and the output OUT1 rises to the “H level” again (at time t3). Next, the prize ball is used as the second detection unit 202.
(OUT2 rises, at time t4).

When the prize ball further flows down from this state,
The spherical surface of the prize ball sequentially deviates from the respective installation positions of the first detection unit 201 and the second detection unit 202, and accordingly, the output O
UT1 and OUT2 are sequentially changed from “H level” to “L level”
(At times t5 and t6). Thereafter, when the prize ball continues to flow smoothly, the outputs OUT1 and OUT2 are output from the above-mentioned t3 to t6.
The waveform expressed between the points is repeatedly output. The above-described prize ball discharge control device 60 (see FIG. 9) monitors the waveforms of the output OUT1 and the output OUT2 generated when the prize ball is discharged, and determines whether the waveform has a characteristic indicating a normal operation. By making a determination, it is determined whether or not the prize ball has been actually ejected.

By the way, as shown in FIG. 10, when the prize ball is normally discharged (without vibrating or bouncing in the sensor), the output signals (OUT1, OUT2) of the first and second detection units are output. ) Satisfies the following conditions.
That is, when the flow of the first prize ball is started, OUT1 and OUT1, both of which have been held at the “H level” until then, will be described.
Out of OUT2, OUT1 falls to “L level” first,
OUT2 subsequently falls to "L level" while UT1 is at "L level". When the second and subsequent prize balls are ejected (as described above, OUT1 and OUT2 are both at “L level” immediately before the second and subsequent prize balls reach the inside of the sensor), OUT1 is first set to “H level”. , And OUT2 rises to “H level”. After that, when the prize ball comes out of the sensor 200, of the OUT1 and OUT2 that have risen together, OUT1 falls first to the “L level”, and OUT2 falls while the OUT1 is at the “L level”. Then falls to "L level". After that, the above-mentioned waveforms are repeatedly generated.

However, as described above, during the actual ejection of the prize ball, the prize ball once passed through the sensor 200 collides with the previously ejected prize ball and rebounds, There is a case where the ball collides with the prize ball and rebounds, or stays in the discharge path 153 near the sensor 200 and starts vibration (chattering). Therefore, the prize ball discharge control device 60 according to the present embodiment detects a bouncing or vibrating prize ball in the following procedure and does not count it. Hereinafter, each of the six typical modes (1) to (6) at the time of abnormal discharge will be described. Note that in the figure, * marks indicate the first and second discharge sensors 200.
3 shows the mounting positions of the detection units 201 and 202.

(1) As shown in FIGS. 11 and 12, the output OU of the second detector is output until the output OUT1 of the first detector falls to "L level" and rises to "H level" again.
When T2 does not fall to the "L level", that is, when O2
If there is no change in the waveform of OUT2 despite the repeated fall / rise of the waveform of UT1 one or more times (between times t11 and t12 and between times t13 and t14 in FIG. 11), the output of OUT1 during this time. The waveform is invalid. Like this
The reason for invalidating the waveform of UT1 is that this waveform is generated only when the sphere B11 vibrates (chatters) between the position indicated by the solid line and the position indicated by the broken line as shown in FIG. is there. As shown after time t15 in FIG. 11, OUT1 first falls from the state where both OUT1 and OUT2 are at the "H level", and then OUT1
When the number 2 falls, the output waveform of the discharge sensor shows the characteristic of the normal state described above, and it is determined at this time that one prize ball has been discharged for the first time.

(2) As shown in FIGS. 13 and 14, the output OUT1 of the first detector rises to "H level" (t31).
(Time) After the output OUT2 of the second detection unit rises (t
After the time point 32, the output O of the second detection unit is output until OUT1 falls to the “L level” again (between time points t32 and t37).
When the UT2 repeatedly falls to the "L level" and rises to the "H level" at least once (between the times t33 and t34 and between the times t35 and t36 in FIG. 13), the output waveform of OUT2 during this time is Invalidate. Thus, OUT
The reason why the waveform 2 is invalid is that this waveform is generated only when the ball B13 vibrates (chatters) between the position indicated by the solid line and the position indicated by the broken line as shown in FIG. is there. As shown after time t37 in FIG. 13, when the output OUT1 falls from the state where both OUT1 and OUT2 are at the "H level" (time t37), and then the output OUT2 falls (time t38), the discharge sensor is detected. Output waveform shows the above-mentioned characteristic at the time of normality, and it is determined at this time that one prize ball has been ejected for the first time.

(3) As shown in FIGS. 15 and 16, when the prize ball flows backward in the discharge path 153 due to bouncing or the like before the prize ball is discharged, both OUT1 and OUT2 are set to the “H level”. In this state, OUT2 falls to "L level" first (at time t51 in FIG. 15), and then OUT2.
UT1 falls to "L level" (time t52). This is a phenomenon that occurs when the ball B15 flows backward from the position indicated by the solid line to the position indicated by the broken line as shown in FIG. 16, and the waveforms of OUT1 and OUT2 generated at this time are invalidated. If a normal prize ball is played from this state, the ball B15 flowing down from the position shown by the broken line has not been counted yet, and the discharging process is performed according to the waveform of the output signals (OUT1, OUT2) obtained thereafter. . In addition, the ball B1 that has flowed back
When 5 does not completely escape from the inside of the sensor 200 to the upstream side, the same waveform (chattering) as in the case of the above (2) is obtained, and processing according to this is performed.

(4) As shown in FIGS. 17 and 18, when the prize ball once flows down the sensor 200, then flows back in the discharge path 153 due to bouncing, and reaches the upstream of the sensor 200 again. OUT1 and OUT2 are both at "L level" at first (before t71),
UT2 rises to “H level” (at time t71 in FIG. 15),
Next, OUT1 rises to the “HL level” (time t72). Output OU when the prize ball moves further upstream
1 falls first (time t73), and then the output OUT2 falls (time t74). This is the sphere B1 as shown in FIG.
7 moves from the position indicated by the solid line to the position indicated by the broken line. If a normal prize ball is played from this state, the ball B17 flowing down from the position shown by the broken line will be counted twice, so that the ball B17 reaches the position shown by the broken line (time t74). Subtracts one from the number of prize balls to be discharged. When the backflowing ball B17 does not completely escape from the sensor 200 to the upstream side, a waveform having the same characteristics as those at the time of the above-described vibration (chattering) is obtained, and processing according to this is performed.

(5) As shown in FIG.
The prize ball (solid line ball B19) located on the upstream side of
After once flowing down the inside of the sensor 200 (the ball shown by the broken line), it flows back in the discharge path 153 by rebound, etc., and reaches the upstream of the sensor 200 again (when it returns to the position shown by the solid line). First, as shown in FIG.
UT1 rises to “H level” (at time t21 in FIG. 20),
Next, OUT2 rises to "HL level" (at time t22, up to this point is the same as in the normal operation). Then, the output OUT2 falls earlier (time t23) and then the output OUT1 falls (t23) before the prize ball moves upstream.
24). When a normal prize ball is played from this state, since the ball B19 has not been counted yet, the above t
All the waveforms obtained between 21 and t24 are invalidated,
Subsequent discharge processing is performed.

(6) Further, as shown in FIG. 21, the prize sphere (solid line sphere B21) already located and counted downstream of the discharge sensor 200 is rebounded by the sensor 20.
Reaches 0 (the sphere indicated by the dashed line) and then flows down again,
When reaching the downstream side of the sensor 200 again (when returning to the position shown by the solid line), as shown in FIG.
UT2 rises to “H level” (at time t25 in FIG. 22),
Next, OUT1 rises to "HL level" (time t26). Then, when the prize ball starts flowing again from the position shown by the broken line, the output OU1 falls first (time t27, the operation from here is normal operation), and then the output OUT2 falls (time t28). When the prize ball B21 moves in this manner, the prize ball B21 is detected twice by the discharge sensor 200, and therefore, when the ball B21 is detected to reach the position indicated by the broken line (t26). At the time point), a process of subtracting 1 from the count value in advance is performed, and then a normal discharge process is performed.

FIG. 23 is a timing chart showing a procedure for detecting the flowing state of the prize ball when there is an abnormality based on the flowing speed of the prize ball by the ball moving time determining means 612 shown in FIG. As shown in FIG.
2 is the detection signal (output OU) of the second detection unit 202 after the detection signal (output OUT1) of the first detection unit 201 falls.
Time T1 (t91 to t92, t9) required until T2 falls.
5 to t96, t99 to t100) and the time T2 (from t93 to t94, t97 to t98) required from the rise of the output OUT1 to the rise of the output OUT2. Is longer than a predetermined value (for example, 1 msec), it is determined that some abnormality has occurred in the prize ball discharge system. That is, (1) As shown between t101 and t104 in FIG. 23, when OUT1 rises (at time t101) and OUT1 falls before OUT2 rises, the time T1 and T2 do not exist. Is determined to be abnormal. (2) As shown from t105 to t108, the time T1 (t105) required from the rise of OUT1 to the rise of OUT2.
If the time (between time t106 and time t106) is longer than the predetermined value, this is determined to be abnormal. (3) As shown from t109 to t112, the time T2 (t111) required from the fall of OUT1 to the fall of OUT2.
If (from time t112 to time) is longer than the above-mentioned predetermined value, it is determined that this is abnormal.

When the ball moving time determination means 612 determines that there is an abnormality in the prize ball discharging operation, the discharge number is not counted based on the signal that caused the prize ball discharging operation (the signal generated at this time is invalidated). )
Ensure that the emission of prize balls is not detrimental to the player.

In this embodiment, the game ball discharging device is applied to a prize ball discharging device. However, if the device is for discharging a predetermined number of game balls, another device such as a ball lending machine may be used. It can be applied to any device.
