Abstract

PROBLEM TO BE SOLVED: To decide the attachment positions of lottery elements on many targets, by means of a simple light emitting/transmitting system. SOLUTION: This device decides an identification area where an arrow 31 is attached, among revolving targets 29a to 29c which include plural identification areas. Two light emitting elements 5a and 5b are placed at one of both sides of an array of those targets together with two light-receiving elements 6a and 6b placed at the other side respectively. Thus, two light beams A and B are generated and cross the front of the targets. Then one of right and left areas which are linearly symmetrical to each other centering on the revolving center O is specified as the timing of the beam A to read the arrow 31 based on a fact whether the arrow 31 crosses the beam A and then the beam B or vice versa. As a result, it is possible to decide the attachment position of the arrow 31 among many targets, just by emitting two common beams A and B across these targets.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lottery determination device that has a plurality of identification regions and determines which identification region of a rotating target a lottery is attached to.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Publication No. 61-52520 has disclosed a lottery determination device using a light beam. In this conventional apparatus, a light beam is formed in the radial direction from the center of rotation of the rotating disk, and the area hit by the arrow is determined based on the timing at which the arrow stuck in the rotating disk crosses the light beam.

Further, Japanese Patent Laid-Open No. 56-88587 discloses the following lottery determination device using a light beam. That is, in this lottery determination device, a light emitting element is provided corresponding to each identification area in the target, and when the arrow hits one of the identification areas in the target, only the light emitting elements belonging to that identification area are caused to emit light, Thereby, the area hit by the arrow is determined.

[0004]

However, in the above-mentioned conventional lottery determination device, it is necessary to individually provide a light beam for one target, and in the case of performing a lottery by combining a plurality of targets, the light beam is required. The optics for forming the must be attached to each target. The present invention
The present invention has been made in view of the above problems, and it is an object of the present invention to make it possible to perform the work of determining the attachment position of a lottery for a large number of targets only by using a simple optical system.

[0005]

In order to achieve the above object, the lottery determination device according to the present invention is (1) arranged so as to irradiate a moving area of a lottery attached to a target and moving with light. At least one light emitting element, and (2) at least two light receiving elements arranged so as to receive the light emitted from the light emitting element and passing through the moving area of the lottery,
(3) Target rotation angle detection means for detecting a rotation angle of the target based on signals from the at least two light receiving elements generated by blocking the light emitted from the light emitting elements by the lottery, (4) It is characterized by having an identification area calculation means for calculating an identification area attached to a lottery on the basis of the rotation angle of the target detected by the target rotation angle detection means.

Now, as shown in FIG. 11, the surface of the target 109 which rotates about the rotation axis O is divided into six identification regions numbered 1 to 6, and further two in front of the target 109. Consider the case of forming light rays A and B of a book.
The lottery 101 is placed in one of the identification areas in the target 109.
When the lottery 101 is attached, for example, when the lottery 101 crosses the ray A, the lottery 10
The identification area to which 1 is attached can be determined. For example, target 1
The specific position of 09 is set as the origin position, and by measuring the rotation angle of the target from the detection of the origin position until the lottery 101 crosses the ray A, the lottery 1
The identification area to which 01 is attached can be determined.

However, when the light ray A crosses the entire target 109 as in the present invention, the lottery 101 crosses the light ray A at two positions on the right side and the left side of the target during one round movement. Therefore, it is difficult to determine which is the read timing. With respect to this point, in the present invention, since another light beam B is formed in front of the target 109 in addition to the light beam A, the orbiting lottery 101 is
On the right side, cross two rays in the order of A → B, and on the left side, cross in the order of B → A. Therefore, by specifying the order in which the arrows are traversed for both rays, the reading timing can be specified at one desired position while the lottery wheel 109 makes one revolution, and as a result, the identification area attached to the lottery wheel 109 can be specified. Can be accurately determined.

FIG. 11 shows a state in which one target is placed on the optical paths of the light rays A and B, but as shown in FIG. 12, a plurality of targets are arranged side by side on those optical paths. Also in this case, the attachment position of the lottery can be individually determined for each of those targets. That is, the attachment position of the lottery can be individually determined for a large number of targets only by at least two light rays without separately providing a light emitting / receiving system for each of the plurality of targets.

Various configurations are conceivable as the target rotation angle detection means for detecting the rotation angle of the target. For example, the rotation angle of the target can be measured by rotating the target with a pulse motor and counting the number of pulses supplied to the pulse motor. Further, by attaching a rotation angle detector called an encoder or the like to the target, the rotation angle can be detected by the detector.

Further, the identification area calculation means, which is means for specifying the identification area in the target on the basis of the rotation angle of the target detected by the target rotation angle detection means, may have various configurations. For example, the relationship between the number of pulses for driving the pulse motor for specifying the rotation angle and the area range of each identification area in the target is stored in advance in a table format in a predetermined storage location, and the target rotation angle detection means It is possible to employ a processing method of reading out the corresponding identification area from the table when the number of pulses is counted.

Various methods are conceivable for forming the above two types of light rays A and B. For example, considering the case where the present invention is applied to three targets, as shown in FIG. 12, two light emitting elements 102a and 102b are arranged on one side of the targets 109a to 109c, and the light emitting elements 1 of them are arranged.
Such rays A and B can be formed by arranging two light receiving elements 103a and 103b on the other side of the target corresponding to 02a and 102b.

In this way, when the plurality of light emitting elements 102a and 102b are arranged on one side of the target and the plurality of light receiving elements 103a and 103b are arranged on the other side of the target,
The light from one light emitting element, for example, one of the light emitting element 102a and the light emitting element 102b, is received by the light receiving element that is not paired with the light emitting element, and thus an error may occur in the determination result. In order to solve this, it is desirable to dispose the light shielding member 104 between the light emitting elements 102a and 102b and the light receiving elements 103a and 103b. The light blocking member 104 prevents the light from the light emitting element 102a from being received by the non-compliant light receiving element 103b and the light from the light emitting element 102b from being received by the non-compliant light receiving element 103a.

As another method for forming the two types of light rays A and B, as shown in FIG.
One light-emitting element 102 is arranged on one side of the light-emitting element 09c, and the light-emitting element 102 is arranged on the other side of the targets 109a to 109c.
It is also possible to dispose two light receiving elements 103a and 103b corresponding to. In addition, as shown in FIG.
09a to 109c, the light emitting element 102a and the light receiving element 103b are arranged, and the other side of the targets 109a to 109c are respectively associated with the light receiving element 103a and the light receiving element 103b.
It is also possible to dispose a and the light emitting element 102b.

In the lottery determination device of the present invention, one light ray A is used as a light ray for determining the reading timing for reading the rotation angle of the target, and the rotation axis O of the target is used.
The ray B is used as a ray for specifying one of the two positions that are line-symmetric with respect to. Of these light rays A and B, the light ray A for determining the reading timing is preferably positioned so as to cross the rotation axis O of the targets 109, 109a to 109c, that is, the front of the rotation center.

When the cam plate 47 rotates in the clockwise direction (arrow C direction) in the figure, one end edge 51a of the notch 51 engages with the pin 43 of the slider 39 and resists the spring force of the spring 42. Push the pin 43 to the right in the figure. When the pin 43 moves up to the notch 44a while pushing the locking piece 44 upward, the locking piece 44 spontaneously falls and the notch 44a engages with the pin 43, whereby
The slider 39 is held stationary by the locking piece 44 with the spring 42 extended. Thereafter, when the cam plate 47 rotates in the counterclockwise direction (arrow C'direction) in the figure at an appropriate timing, the other end edge 51b of the notch 51 comes into contact with the bottom side of the locking piece 44, and further moves it upward. Push up. Then, the notch portion 44a of the locking piece 44 is disengaged from the pin 43, and as a result, the slider 39 is instantaneously and vigorously moved to the left in the figure by the spring force of the spring 42. Due to this movement, the arrow 31 placed on the arrow rail 38 is pushed by the slider 39 and is thrown out of the firing tube 33 as indicated by an arrow D.

One end of a wire 52 is connected to a proper position of the cam plate 47, and the other end of the wire 52 is wound around a rotary cylinder 53 integrated with the model doll 34. The rotary cylinder 53 is biased by a spring 54 so as to rewind to the initial position. Cam plate 4
When 7 swings and rotates in the direction of arrow C-C 'to shoot the arrow 31, the wire 52 is unwound or unwound from the rotary cylinder 53 in response to this, and the model doll 34 is thereby rotated. . As a result, a visual stimulus is given to the player, and it is possible to inform the player that the arrow is ready to be fired.

As shown in FIG. 5, the arrow 31 has a tip large diameter portion 55a of a slender and generally cylindrical handle 55 made of plastic.
It is manufactured by fitting a suction cup 56 into the. A locking piece 59 having a hole in the outer edge portion of the non-suction surface of the suction cup 56

Returning to FIG. 1, the first light-emitting element 5a and the second light-emitting element 5b are located on the right side of the rightmost target 29c.
Individual light emitting elements are arranged. These light emitting elements can be constituted by, for example, a light emitting diode, a small light bulb, or the like.
Further, two light receiving elements, that is, the first light receiving element 6a and the second light receiving element 6b, are arranged on the left side of the leftmost target 29a. These light receiving elements are, for example, photodiodes,
It can be constituted by a photoelectric conversion element using a photoelectric tube.

As shown in FIG. 6, the lower first light emitting element 5
The light emitted from a is the lower first light receiving element 6a which forms a pair with it.
The light beam A is formed by the received light. Further, the light emitted from the upper second light emitting element 5b is received by the upper second light receiving element 6b which is paired with the second light emitting element 5b, whereby another light ray B is formed. Both of these light rays A and B cross the front positions of the respective targets 29a to 29c without crossing each other. That is, when the arrows 31 are attached to the respective targets 29a to 29c, these light rays A and B move around in accordance with the rotation of the targets.

When the object passes the origin position where the origin sensor 9 is provided, the detection piece 8 is detected by the origin sensor 9.

FIG. 8 is a block diagram showing the main part of the control device used in the lottery game machine of this embodiment. This control device is configured by using a computer, and a series of lottery games is calculated by a lottery game calculation unit according to a game program stored in the memory 11. Further, the CPU 10 includes an origin sensor 9, a first
Output signals from the respective elements of the light receiving element 6a, the second light receiving element 6b, the pulse number-target area table 12 and the pulse generating section 14 are sent. The pulse generation unit 14 uses each of the targets 29a to 29a.
The pulse signal S _P for driving the pulse motor 69 for rotating 29c is output. Further, inside the pulse number-target area table 12, data regarding the number of pulses input to the pulse motor 69 and the area range of each identification area in the target corresponding to the number of pulses is stored.

The operation of the lottery game machine having the above structure will be described below. First, in FIG. 1, a player stands in a vacant place of each of the voting stages 2a to 2f, and inserts an appropriate number of medals from the medal insertion slot 13. Then, further, a button operation, a switching operation, and other appropriate operations are performed to vote a three-digit number. After that, the targets 29a to 29c are driven by the pulse motor 69 (FIG. 2) and are sequentially fired at appropriate time intervals.

The fired arrow 31 reaches a corresponding target after flying in the air and is attracted to the target by the action of the suction cup 56. Three arrows 31 have three targets 29a to 29c
The three-digit number is determined depending on which of the identification areas is adsorbed. If the number or the like determined in this way matches the number previously voted by the player, it is won and a predetermined number of medals are awarded to the player as a prize. The player can use the medals that he / she has acquired when he / she desires, in the medal exit 16
Can be taken from.

The firing operation of the arrow 31 will be described in more detail as follows. In FIG. 4, an arrow 31 is an arrow rail 38.
It is placed in a predetermined position above and waits. At this time, the string 61 is
As indicated by reference character G in FIG. 3, it hangs downward due to its own weight. Under this state, in FIG.
The motor 49 in 8a to 28c is operated to rotate the cam plate 47 in the counterclockwise direction (direction of arrow C ') in the figure. When the cutout edge 51b of the rotating cam plate 47 moves to the position of the locking piece 44, the locking piece 44 is pushed upward, and the cutout 4 is formed.
4a disengages from the pin 43 of the slider 39, and as a result, the spring force of the spring 42 causes the slider 39 to instantaneously move to the left in the drawing.

By the movement of the slider 39, the arrow 31 is pushed by the slider 39 and thrown out of the firing tube 33. The thrown arrow 31 flies through the space on the game field 4 in FIG.
Reach 9c. Since the suction cup 56 is attached to the tip of the arrow 31 as shown in FIG. 5, the arrow 31 is attracted to the targets 29 a to 29 c by the suction cup 56. Arrow 31 is target 2
When flying towards 9a-29c, the string 61 is taken out of the launching devices 28a-28c along with it, so that the downward hanging of the string 61 is gradually reduced. When the arrow 31 adsorbs to the targets 29a to 29c, the code H
As shown by, the string 61 hangs down a little.

When a predetermined time elapses after the confirmation of the adsorption of the arrow 31 on the targets 29a to 29c is completed, the arrow 31
Is performed to return the arrow to the arrow firing devices 28a to 28c. Specifically, in FIG. 3, the motor 25 is operated to move the traveling body 22 from the first position P1 to the second position P2. Then, the string 61 is pulled by the traveling body 22, and as a result, the arrow 31 is pulled off from the targets 29a to 29c and drops onto the game field 4, and while being dragged by the string 61, the firing tube 33 is passed through the recovery port 72.
Is stored inside. When the arrow 31 is stored in the predetermined position, the tail portion of the arrow 31 is located at the side plate through hole 66 in FIG. 2, and the tail portion of the arrow is detected by the reflective optical sensor 68. As a result, it is detected that the arrow 31 has been set at the predetermined standby position in the arrow firing device.

When the arrow 31 is detected by the optical sensor 68, the motor 25 in the recovery device 20 shown in FIG. 3 starts reversing based on the detection of the arrow 31, and the traveling body 22 is moved to the second position P2.
To the first position P1. As a result, the string 61 slackens again and hangs down as shown by the arrow G, and waits for the next arrow firing operation.

The determination work for determining which identification area in each of the targets 29a to 29c the arrow 31 is attached to will be described below. In order to make the description easy to understand, in the following description, as shown in FIG. 6, it is assumed that the arrow 31 is attached to the identification area in which the “2” is marked in the target 29a.

In FIG. 6, when the target 29a rotates while holding the arrow 31, the detection piece 8 attached to the target 29a.
When reaches the origin position where the origin sensor 9 is provided, an output pulse P ₀ appears at the origin sensor 9, as shown in FIG. Further, in FIG. 6, the arrow 31 sequentially crosses the light ray A and the light ray B at appropriate time intervals according to the rotation speed of the target 29a, and as a result, as shown in FIG.
a and the second light receiving element 6b alternately output pulses P _A and P
_B appears. The order of appearance of these output pulses alternately changes with time, such as B → A, A → B, ..., A → B, B → A ,. The change from A to B is shown in Fig. 6.
In the case where the arrow 31 crosses the light rays A and B on the right side of the target 29a, the change from B to A is that the arrow 31 has the target 29a.
Of light rays A and B on the left side of.

When the CPU 10 (FIG. 8) changes the output pulses P _A and P _B from A to B, that is, when the arrow 31 crosses the rays A and B on the right side of the target 29a in FIG. The number of pulses of the motor pulse signal S _P supplied to the pulse motor 69 is counted from the output of the origin pulse P ₀ to the output of the output pulse P _A of the first light receiving element 6a (time E). When the number of pulses from the origin position is measured in this way, the identification area corresponding to the number of pulses is read out based on the look-up table 12 (FIG. 8), and the identification in which the arrow 31 is attached is based on the read area. It is determined to be a region.

At this time, the output pulse P of the first light receiving element 6a
Read timing of _A, neither rising Ta of the output pulse P _A, neither falling Tb, are set to their central point Tc. The reason for processing in this way is as follows. That is, as shown in FIG.
When the target 29a is attached to the position N close to the rotation center O of the target 29a, the width of the output pulse P appearing in the light receiving element becomes wider than when it is attached to the position T far from the rotation center O. Therefore, pulse rise Ta and fall T
When the motor pulse is read at b, it is conceivable that an error will occur in the measurement result due to the difference in the mounting position of the arrow 31 in the radial direction. On the other hand, if the median value Tc of the rising Ta and the falling Tb is set as the reading timing as in the present embodiment, stable measurement without variation is performed even when the mounting position of the arrow 31 changes in the radial direction. be able to.

In the present embodiment, while the target 29a is rotating, the above-mentioned identification region determination processing is executed a plurality of times,
When the same identification area is continuously calculated a predetermined number of times as a result of the determination process, the identification area is determined as the area to which the arrow 31 is attached. This is for avoiding the occurrence of a detection error when the arrow 31 is attached to the boundary line between two identification areas adjacent to each other or at a position close thereto.

The above description is the processing for determining the attachment position of the arrow with respect to the leftmost target 29a in FIG. It However, while determining the attachment position of the arrow for each target, the remaining two targets stop their rotations. Otherwise, it is impossible to distinguish whether the arrow 31 that crosses the light rays A and B belongs to the target that is the target of the determination, or whether it belongs to other targets.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to those embodiments and can be variously modified within the technical scope described in the claims. For example, the lottery determination device of the present invention can be applied to any device other than the lottery game device described above. For example, it can be applied to a simple lottery device having no game element. Further, the lottery is not limited to an arrow flying in the air, but may be a moving object moving on a rail or any other moving object. Furthermore, the number of targets to be determined is not limited to three as in the case of the above-described embodiment, but can be one, two, or four or more.

Further, the target rotation angle detecting means for detecting the rotation angle of the target based on the timing at which the lottery crosses the light beam is of the type for counting the pulse signals for driving the motor as mentioned in the above embodiment. Not limited to further,
The identification area calculation means for calculating the identification area attached to the lottery based on the rotation angle of the target detected by the target rotation angle detection means is not limited to the calculation method using the lookup table as in the above embodiment. .

According to the lottery determination device of claim 1,
Since the attachment position of the lottery is determined using at least two kinds of light rays formed by at least one light emitting element and at least two light receiving elements, no matter how many targets are present, each light ray can be used for each of those light rays. As long as they are located across the targets, their rays can determine the attachment position of the lottery for those multiple targets. That is, it is possible to deal with a plurality of targets only by at least one light emitting element and at least two light receiving elements, without attaching a light emitting / receiving system to each of the plurality of targets.

According to the lottery determination device of the second, fourth and fifth aspects, the at least two types of light rays can be formed by a very simple optical structure.

According to the lottery determination device of the third aspect, when the light emitting element group and the light receiving element group are separately arranged on both sides of the target as in the lottery determination device of the second aspect, they are individually arranged. It is possible to prevent the light receiving element of erroneously receiving the light from the incompatible light emitting element.

In the conventional lottery determination device in which one emitting / receiving system is provided for one target, the number of targets is three.
If there are more than three, it is necessary to prepare three or more emitting / receiving systems. On the other hand, in the lottery determination device of the present invention, at least one light emitting element and at least two light receiving elements are sufficient even when the number of targets is three or more. Therefore, the lottery determination device of the present invention is particularly advantageous when the number of targets is plural as described in claim 6.

According to the lottery determination device of the seventh aspect, the accuracy of the determination is improved as compared with the case where the light beam for detecting the rotation angle is traversed at a position displaced from the center of rotation of the target.

According to the lottery determination device of the eighth aspect, even when the lottery child is attached to the center side of the target, or
There is no variation in the accuracy of the determination result even when the target is attached to the outer peripheral side.

According to the lottery determination device of the ninth aspect, it is possible to avoid making an error in the determination result when the lottery elements are attached to the boundary lines of the identification areas adjacent to each other in the target or in the vicinity thereof.
