Description

[Detailed explanation of the invention] [Field of application of the invention] This invention relates to a safe ball counting device that is installed opposite to an electrically variable batted ball prize device attached to the game board of a pachinko machine, and will be explained in more detail. For example, a door-shaped or blade-shaped opening/closing member installed opposite to the batted ball winning opening in the main body (also simply referred to as the device body) of the winning device is opened and closed by an electric member such as an electromagnetic solenoid, and the opening/closing member is operated according to the setting conditions. This is carried out on winning devices that are kept open for a considerable period of time.
And a safe ball counting device that detects the safe balls (valid balls that are given the value of rescuing a predetermined number of balls as a reward for the gamer) generated by the winning device and counts the number of balls. Regarding.

[Background of the idea]

Taking the well-known electric variable batting ball winning device, which is generally referred to as an "attacker-type accessory or winning device," as an example, this type of device has its own unique differences in shape, size, design, color, etc. However, the basic structure is the same, and as shown in Figs. 2 to 5, there is a prize winning device container 21, a horizontally long hit ball prize opening 22 formed in the center of this container 21, and this prize winning mouth 2.
A box frame 23 attached or integrally formed on the back surface of the container body 21 so as to surround the box frame 2, and a horizontally long opening/closing plate 24 that is pivotally supported by the box frame 23 and placed opposite to the batted ball winning hole 22.
and an electromagnetic solenoid 25 installed on the back side of the body 21 and linked to the opening/closing plate 24, and connected to an appropriate electric control circuit (not shown), and as shown in FIGS. 10 and 11. It is attached to the bottom center of the game board G.

As an example of the operational settings in such an embodiment,
In response to the occurrence of the start input condition during the game, the electromagnetic solenoid 25 is energized for a set time, and the opening/closing plate 24 is operated to the forward position where it can accept a batted ball, opening the prize opening 22. Following the demagnetization of the solenoid 25, the opening/closing plate 24 is returned to its original upright position and closes the prize opening 22. Therefore, as can be understood from the above, in such a winning device,
The excitation time of the electromagnetic solenoid 25, that is, the opening/closing plate 24
The longer the opening time, the more batted balls can be effectively accepted and generated as safe balls. In addition, in this type of winning device, the ball received by the opening/closing plate 24 is referred to as a safe ball after it enters the winning hole 22, and for convenience, the safe ball is generated at the passing point of the winning hole 22 (the point where the safe ball is generated). As illustrated in FIG. 8, the positions S ₁ , S ₂ , S ₃ ) are about 45 degrees upward relative to the horizontal line passing through the center of the support shaft 24A.

For this reason, in recent years, with the aim of optimizing the game in pachinko machines equipped with this type of device, the number of winning balls in the winning device has been regulated. reduction of the effective winning area (effective receiving area of the opening/closing plate 24).

(b) Shortening the maximum opening time of the opening/closing plate 24 (set excitation time of the electromagnetic solenoid 25).

C. Count detection regulation of the number of winning balls, that is, the number of safe balls.

The following three items will be made compulsory. In practice, while trying to prevent the opening/closing plate 24 in the open state from accepting multiple batted balls over a wide area at the same time, if the appropriate number of N batted balls enters the prize within the opening time of the opening/closing plate 24, that is, N At the end of counting detection of safe balls, the electromagnetic solenoid 25 is demagnetized and the opening/closing plate 24 is closed accordingly, and even if the number of batted balls is less than N, the solenoid 25 is demagnetized after the set excitation time of the solenoid 25 has elapsed. It is specified that the follower opening/closing plate 24 is closed.

In view of these regulations, it is of course important to technically deal with the above-mentioned matters A, B, and C, but it is not limited to this, and rapid passage of safe balls and count detection become major issues, and the above-mentioned problems also arise. It is important to appropriately determine the passage path length and passage time from the safe ball generation position to the count detection position of the switch, and to shorten the detection time required to count and detect each safe ball. By the way, the final N
Since the solenoid 25 is still in the energized state until the number of safe balls is counted and detected, if the required detection time is long, the opening/closing plate 24 remains open for an extended period of time. As a result, when the opening/closing plate 24 is opened, a problem arises in that more balls than the prescribed number win and extra safe balls are generated.

[Summary of the idea]

The present invention was newly devised in view of the above-mentioned background, and the case body installed on the back side of the electric variable batted ball winning device has a safe size that fits the batted ball receiving area of the opening/closing member. A ball passage area is formed, and first and second safe ball passage passages are formed independently from the left and right sides of this passage area toward the center, and the exits of both sides are common. A switch for safe ball count detection is installed at the bottom of the entrance path, and the ball detection part faces the exit, thereby reducing the length of the safe ball entrance path and the count detection time. It is a detection device.

[Purpose of invention]

The purpose of the present invention is to quickly pass the safe balls and detect their count to regulate the number of safe balls generated within the set opening time of the opening/closing member, thereby optimizing the pachinko game.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS A safe ball counting device according to the present invention will be described with reference to preferred embodiments illustrated in the accompanying drawings. Before explaining this example device, an additional note about the illustrated winning device is that a known photo switch 26 for detecting lucky balls is installed at the center of the back side of the winning hole 22. This switch 26 detects one of the safe bulbs as a locking bulb for re-opening the opening/closing plate. The sensor base 28 is attached to the sensor base 28 and directs the light emitting element to the passage in the main body 27, and the swinging piece 29 is pivotally supported in the passage in the main body 27 and has a reflective surface for the light emitting element. When the swinging piece 29 is pushed by the passing safe ball, the sensor board 28 detects light and turns on. However, the switch 26 is set to detect only the first safe ball that pushes the swinging piece 29 as a lucky ball.

The counting device of this example, which is implemented for the above-mentioned winning device, has a device body 2 as shown in FIGS. 1 to 8.
The case body 1 is detachably attached to a box frame 23 on the back side of the case body 1, and a detection switch 12 for counting is fitted and set in the lower part of the body 1. In the above case body 1, the vessel body 2
1. A horizontally rectangular base screwed to the back surface 2. A pair of regulating walls 3, 3 are protruded from both sides, and between the two walls 3, 3,
A safe ball passing area Z is formed that matches the ball receiving area of the opening/closing plate 24 in the winning device, and guide troughs 4 and 5 extend from the lower ends of the regulation walls 3 and 3 on each side toward the center of the base 2. The first and second passages R 1 _and R 2 for the safe balls are formed, and a common exit at the end of both passages R ₁ and _{R 2 is} formed between the tips of both guide troughs 4 and 5. 6 is open. The base 2 is fixed with its upper edge at the same height or slightly lower than the lower edge of the winning opening 22 in the winning device, and has a relief recess 7 for the photo switch 26 formed in the center of the upper edge. Regarding the guide troughs 4 and 5, the first side (left side in the drawing) is long and the second side (right side in the drawing) is short, and each has two slopes with different slopes, and the tips of each other are formed to be short. They are aligned at the same height. As a result, the safe balls are quickly passed through each entry route R ₁ and R ₂ , and the flow and speed of the safe balls in both entry routes R ₁ and R ₂ are changed and different, and the safe balls are passed through the exit 6. Interference (bridge condition) in the parts can be avoided. Note that the exit 6 is located at a position that is a radius of the ball from the center of the safe ball passing area Z toward the second passing route _R2 , and
offset from the outlet of the body 27 at.
Reference numeral 8 denotes a receiving plate projecting horizontally from the lower edge of the base 2, and a fitting portion 9 for a switch is formed between this receiving plate 8 and the guide gutter 4 on the first side. Numerals 10 and 11 are seats recessed in the surface of the base 2 in alignment with the outlet 6 and the fitting portion 9.

On the other hand, the detection switch 12 for the early counting is of a known proximity type, and is a rectangular tube with a magnetic coil built into one side of a thin rectangular main body 13 that has a ball passage detection section, that is, a magnetic coil around the inner periphery of the safe ball passage hole 15. It has a shaped detection section 14, and the same switch 12.
The main body 13 is tightly fitted into the fitting part 9 and positioned by one seat 10, and the detection part 1 is
4 is positioned by the other seat 11, and its through hole 15 is aligned with the outlet 6, and the entire case body 1 is set horizontally and detachably. Note that this switch 12 is implemented in the same way as before, and is connected to a count circuit and a solenoid drive circuit (not shown) in a control circuit device that is common to the switch 26 and electromagnetic solenoid 25 on the winning device side. , and in the energized state, every time the safe bulb enters the detection unit 14, it is activated to detect a count, and in synchronization with the time when the count is detected N times, the solenoid 25 is activated immediately regardless of the excitation time remaining. demagnetized. Reference numeral 16 indicates a lid detachably attached to the case body 1.

The counting device of the main body configured as described above is set on the back side of the container body 21 of the winning device, so that the counting device of the main body 27 of the photo switch 26 located in the center of the winning area Z serves as a passing route for the safe ball. The first and second entrance roads R ₁ on the left and right are divided into
A total of three routes (indicated by A, B, and C in FIG. 6) are configured: a route passing through R ₂ and a route passing from the passage in the main body 27 to the center of the case body 1. Therefore, the safe ball generated when the batted ball received by the opening/closing plate 24 passes through the winning hole 22, quickly passes through any of the above-mentioned routes A, B, and C without any hesitation, and then passes through any of the three routes. The count is detected while passing through the detection section 14 of the detection switch 12 from the common outlet 6, and after passing through the through hole 15, the ball is introduced into the safe processing section as before.

In each of the above-mentioned entry routes A, B, and C, the required detection time to count and detect safe balls is:
If we look at the transition locus length of the center of the safe sphere instead of the passing distance, we can see that the lower surface of the detection part 14 of the detection switch 12 is detected from the safe sphere generation positions S ₁ , S ₂ , S ₃ as shown in FIGS. 6 to 8. In other words, the actual length of passage up to the exit end position E of the through hole 15 is the actual length of each passage, and the actual length of each passage is defined as the length of each section (A ₁ to A ₄ , B ₁ indicated by the two-dot chain line in the figure).
~B ₄ , C ₁ ~ _{C 3} (A ₄ , B ₄ , and C ₃ are common passages with the same section length), and the results were measured separately.
The sum of all actual passing lengths must be no more than 1.5 times the batted ball passing area specified in the winning device. And even on the A path side where the actual passing length is the longest, it is only about 53 mm at most, and the ball that fell onto the opening/closing plate 24 enters the winning hole 22 with appropriate force and becomes a safe ball after that. Even if we consider the time required to pass through the route as the required detection time, it is extremely short. By the way, B and C
The actual lengths of passage for the routes are approximately 44 mm and 33 mm, and the required safe ball detection time for each is much shorter than that for route A.

Therefore, in the winning device, the maximum number of safe balls is N.
Even if the Nth batted ball enters the prize and passes through the A route as the Nth safe ball under the stipulation that the number of balls is within 1, the switch 12 will count the safe ball after the minimum required detection time. The electromagnetic solenoid 25 is demagnetized immediately after detection (which is much shorter than the required detection time and can be considered simultaneous), and in synchronization with this, the opening/closing plate 24 is instantaneously closed. As a result, it is possible to restrict the winning of more batted balls than the specified number (N+1 or more) during the game, and thereby to restrict the number of safe balls that occur. It should be noted that it is extremely rare and possible that the Nth and N+1st balls from both sides of the opening/closing plate 24 win the prize at the same time, but in this case, the N+1th ball will pass as a valid safe ball. detected, but not detected.

[Example of change]

Counting devices that are the object of the present invention are not limited to the disclosed example described above, but other methods are also proposed. That is, as another example of the case body 1, regarding the regulating walls 3, 3 and the guide troughs 4, 5 formed on both sides of the base 2,
Right angle shape, dogleg shape, shown in Figure 9 a, b, c, respectively,
It may be a passage wall having a circular shape or the like and arranged symmetrically on both sides, or it may be arranged symmetrically on each side with appropriate differences in shape, length, slope, etc. In short, it is desirable to appropriately select the external shape and size of the case body 1 to make the safe ball passage area Z as narrow and shallow as possible, thereby shortening the passage time. Also, switch 12 for counting
It is desirable not only to have high performance, but also to have a size that shortens the passage time of the safe ball. By making any counting device removable, it can be removed when counting detection is not required and the winning device can be operated independently.
The present invention can be applied to other winning machines of this kind with different designs, and can also be applied to other winning machines in which opening/closing wings are provided on both sides of the winning zone.

As described above, the present invention is a safe ball counting device implemented in an electric variable batted ball winning device in which opening/closing members such as door plates and blades are kept open for a considerable period of time using electric members such as electromagnetic solenoids. It has a case body that is installed on the back side of the winning device, and a counting switch that is installed in this body and is connected to the counting circuit and solenoid drive circuit of the control device. While narrowing the safe ball passage area as much as possible and shortening the first and second safe ball passageways formed on both sides within the case body, the terminal ends of both passageways are By having the ball detecting section of the switch facing the common exit opened in the case body, the safe ball can be quickly passed through the case body, and the time required for detecting the safe ball can be shortened, resulting in instantaneous detection. This allows count detection.

Therefore, in a prize-winning device that implements the device of the present invention, when a plurality of batted balls win prizes while the opening/closing member is open, and the counting detection of a specified number of safe balls is completed, the electric member is synchronously activated. According to the immediate return of the ball, the closing member can be closed, and it is possible to restrict the winning of more batted balls than the prescribed number, thereby regulating the number of safe balls that occur, thereby making it possible to optimize the game.
