Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a projection device that projects an image onto a screen.

Among the above devices, a device in which a light source is placed at an appropriate position, an appropriate pattern is placed between the light source and the screen, and a light image of the pattern is projected on the screen by the light emitted from the light source is a good device. Are known. For example, there is a shooting device for play in which a pattern image projected on a screen is used as a target, and the target is illuminated with light from a separately provided light beam gun to compete for better or worse points. However, in the conventional projection devices used in this type of shooting equipment, the pattern placed between the light source and the screen is either fixed in a fixed position or is simply made to fly over the screen to resemble clay in clay shooting. , only a single pattern is always displayed on the screen. Therefore, when used as a shooting device for play, it lacks realism, and the game itself is monotonous with little variety.

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a projection device that can project a changing pattern on a screen.

Hereinafter, the present invention will be explained using drawings showing embodiments thereof.

FIG. 1 is an overall view of a recreational shooting device using a projection device according to the present invention. Although not shown,
The projection device is built into the control box 1. A light image created by this projection device is projected onto a screen 2. screen 2
A certain pattern, such as a diagram showing outer space, is drawn in advance. Therefore, it is desirable that the image projected by the projection device be a pattern corresponding to the image, such as a pattern of a spaceship or space dust.

Two ray guns 3 are placed in the control box 1 in advance. The contestant removes one of the ray guns 3 from the control box 1, holds it in his arm, and shoots, that is, shoots down the pattern projected on the screen 2 with light. When light hits the pattern, it is detected by a well-known detection method, and a score is added and displayed on the display board 4. The person with the most points is the winner.

An example of a projection device built into the control box 1 is shown in FIG. In the figure, two frames 6 and 7 extending upward are fixed on a base 5 fixedly disposed within a box 1. The upper end of the shorter frame 7 is bent at a right angle, and a lens 9 is attached via a bracket 8 on the plane of the bent portion. A lamp 11 as a light source is attached to the upper part of the longer frame 6, and the light from the lamp 11 passes through a lens 9 and a reflecting mirror placed to the right of the lens 9 along an optical path 12 shown by a dashed line. 13 to reach screen 2.
The screen 2 is the same as that shown in FIG. 1 with the same reference numerals.

The motor 1 is located under the bent part of the short frame 7.
4 is attached to the motor 14, and one end of a rotating shaft 16 is connected to the output shaft 15 of the motor 14.
The other end of the rotating shaft 16 is supported by a bearing 17 fixed to the long frame 6. Rotating shaft 16
A disk 21 as a gear support plate and a sun gear 22 as a first gear are fixed in order from the right on the axis of the gear. As shown in FIG. 3, the disk 21 is fixed on the same circumferential orbit 23 at such a position that four supports 24 are at right angles to each other.
A through hole 25 of an appropriate diameter is provided at the center of each support 24.

The one-way clutch 18 is shown in FIG.
(When viewed from the direction of arrow A in the figure) When the motor shaft 15 and thus the rotating shaft 16 rotate counterclockwise, the rotation is transmitted to the disk 21, but when the rotating shaft 16 rotates clockwise, the rotation is transmitted. do not. Therefore, when the rotating shaft 16 rotates in the first direction, for example, clockwise, the sun gear 22 rotates but the disk 21 remains stationary. On the other hand, when the rotating shaft 16 rotates counterclockwise, both the sun gear 22 and the disc 21 rotate together. In order to rotate the rotating shaft 16 in both forward and reverse directions, the motor 14 is capable of rotating in both directions.

As can be seen from the above explanation, the support 24 on the disc 21 moves on the circumferential orbit 23 in accordance with the counterclockwise rotation of the disc 21. When intersecting the optical path 12 (FIG. 2), the light from the lamp 11 passes through the through hole 25 of the support 24 (hereinafter, this position will be referred to as the optical path position of the support 24). In the normal state during play, the stand 24 is placed at the above-mentioned optical path position, but the following method is adopted to determine whether or not the stand 24 is at this position. That is, disk 2
One notch 26 is provided in each portion of the outer circumferential surface of 1 that corresponds to the position where the abutment 24 is placed, and when one abutment 24 is in the optical path position, one of the notches 26 has a micro The actuator 28 of the switch 27 is depressed to switch the switch. It is free to decide where to drop it into the notch.

As shown in FIG.
9 is arranged, and two pins 31 are set up on one side of the planetary gear 29. These pins 31
As shown in FIG. 2 or 4, the gear 29
A pattern support plate 32 extending parallel to is fixed,
Furthermore, a pattern plate 34 is rotatably attached to a pin 33 erected on the pattern support plate 32. The position of the support plate 32 corresponding to the through hole 25 of the abutment 24, therefore the optical path 12 (second

4 has two short and long arms 34 as shown in FIG.
a, 34b, and one guide pin 35 is attached to pass through both arms. The guide pin 35 is attached to the support plate 3 as shown in FIG.
The guide hole 36 is fitted into an arc-shaped guide hole 36 formed to have an appropriate length around a pin 33 provided on the holder 2. Therefore, the pattern plate 34 has guide pins 35
within the range in which it can move within the guide hole 36,
Rotation around the pin 33 is possible. however,
A torsion coil spring 37 is disposed between the pattern plate 34 and the support plate 32, so that one end is engaged with the guide pin 35 and the other end is engaged with one of the support plate fixing pins 31. 35 is normally pressed against one end side of the guide hole 36.

The tip of the longer arm 34a of the pattern plate 34 is formed into a rectangular shape that spreads laterally, and a character pattern 38 and an explosion pattern 39 are formed in this part.
Two projection patterns are created. These patterns are formed by punching holes in the pattern plate 34 in the shapes shown in the drawings. As mentioned above, the pattern plate 34 has guide pins 35 connected to guide holes 36.
In this state, the character pattern 38 corresponds to the hole 30 in the support plate, and the optical path 12 (the second

3 and reaches the screen 2, whereupon a character image having the same shape as the character pattern 38 is projected onto the screen 2. The character image may have any design, but as described above, in this embodiment, where a screen imitating outer space is used, a design of a spaceship or the like is preferable.

Explosion pattern 39 is character pattern 3
It is made in a shape that imitates the state in which 8 exploded.
Resisting the spring force of the coil spring 37, the guide pin 35
the pattern plate 3 until it reaches the other end of the guide hole 36.
4, the explosion pattern 39 replaces the character pattern 38 and comes to a position where it intersects the optical path 12.

A pattern switching device, generally indicated by the reference numeral 41 in FIG. 4, is a device for switching between the character pattern 38 and the explosion pattern 39. This pattern switching device 41 is rotatably supported by a solenoid 42 fixed to the lower part of the long frame 6 (FIG. 2) facing the short frame 7, and a support shaft 43 fixed to the upper part of the long frame 6. Approximately L
A letter-shaped deflection lever 44 and a similarly long frame 6
an action plate 46 rotatably supported by another support shaft 45 fixed to the upper part of the deflection lever 44; a spring rod 47 connecting the rod 42a of the solenoid 42 and one arm 44a of the deflection lever 44; An action rod 48 connecting the other arm 44b and the action plate 46
and has. In the illustrated state, the solenoid 42 is
In the case of OFF, the action plate 46 is located at a position separated from the guide pin 35 of the pattern plate 34 located at the optical path position. When the solenoid 42 is turned on, the deflection lever 44 rotates counterclockwise, and at the same time, the action plate 46 also rotates counterclockwise. Action plate 4
6 rotates counterclockwise, the working surface 46a of the working plate 46 collides with the upper part of the guide pin 35 (see FIG. 2), and the pattern board 34 is pushed toward the other end of the guide hole 36. Guide pin 35 is in guide hole 3
When the other end of 6 is reached, the character
Explosion pattern 39 will be placed in place of pattern 38, and therefore screen 2 (Figure 2)
An explosion image corresponding to explosion pattern 39 is displayed above.

The support plates 32 attached to each of the four abutments 24 are positioned at almost right angles to each other as described above, so when one support plate 32 is in the optical path position, the support plates 32 are in the opposite position. The support plate 32 is placed in the lowest position offset by approximately 180°. Further below the support plate 32 located at the lowest position, a photo switch 51 mounted on a fixed base 49 fixed to the base 5 is arranged. When the planetary gear 29 rotates, the support plate 32 fixed thereto also rotates, but the tongue piece 32a of the support plate 32 that rotates in this way cannot pass through the detection groove 52 (FIG. 2) of the form switch 51. can.

The projection apparatus according to this embodiment has the above configuration and operates as follows.

First, when the power for the entire amusement machine is turned on, the lamp 1
1 lights up, and a non-rotated character image is projected onto the screen. At this time, in FIG. 2, the reflecting mirror 13 is swung as indicated by the arrow BB' to cause the character image to fly on the screen.

On the other hand, as shown in FIG. 1, the player stands in front of the screen 2 holding the ray gun 3 and fires a ray of light toward the character image projected on the screen 2.
When the emitted light beam hits the character image, a first hit signal is sent to a control section (not shown) using a well-known discrimination method. In response to this first hit signal, the direction of swing of the reflecting mirror changes, and at the same time, the motor 14 is started and the rotating shaft 16 rotates clockwise in FIG. 3.
In this case, due to the action of the one-way clutch 18, the disk 21 remains stationary, but the sun gear 22 rotates clockwise and therefore the planet gears 29 rotate counterclockwise. The rotation of the planetary gear 29 rotates the support plate 32 and the pattern plate 34 fixed thereon, and therefore the character placed in the optical path position rotates.
Pattern 38 rotates in that position. As a result, a character image is obtained on the screen 2, which rotates while changing its flight direction as if it were repelled by the light beam emitted from the light gun.

As a result, the player flies in a direction different from the direction in which he originally flew, and then aims at the rotating character image. When a second hit signal of this character image is sent to the control section, the direction is further changed.

This direction change is performed by swinging the reflector in response to input of a hit signal to the control unit.

In this way, the character image changes direction and flies every time it hits, and when the third hit signal (third hit signal) is sent to the control section, the character's explosion image can be reproduced on the screen.

This is done as follows.

During the competition, in FIG. 4, while the support plate 32 at the optical path position rotates, the support plate 32 at the lowest position
is also rotating, but each time the tongue piece 32a of the lowest support plate 32 passes the detection groove 52 (FIG. 2) of the photo switch 51, the photo switch 5
A support plate position signal is sent from 1 to the control section.

The control unit that received this support plate position signal and the third hit signal sends a stop signal to the motor 14,
This stops the motor 14 and the rotation of the character pattern 38 as well. At the same time, current flows through the solenoid 42 and the action plate 46 rotates counterclockwise, rotating the pattern plate 34 against the spring 37 until the guide pin 35 is regulated by the guide hole 36, causing the explosion pattern 39 to rotate. Move it to the optical path position.
As a result, an explosion image is displayed on the screen 2 instead of the previous character image, and the player can see that the light beam has hit the character image and caused it to explode.

The solenoid 42 is turned off after a predetermined time after being turned on, and the lamp 11 is also turned off at the same time. The pattern plate 34 then returns to its normal state with the character pattern 38 in the optical path position. The above is the explanation from the rotation of the character image to the explosion, and the character change is performed as follows. First motor 1
4 rotates in the opposite direction, that is, counterclockwise. The rotation of the motor 14 in the opposite direction is transmitted to the disk 21 by the one-way clutch 18.
rotates counterclockwise, which causes the planetary gear 29
revolves around the sun gear 22. This revolution brings a new pattern plate 34 to the optical path position, which was at a position shifted by 90° from the pattern plate 34 that had been placed at that optical path position. When the new pattern plate 34 reaches the optical path position, further
The actuator 28 of the micro switch 27 falls into the notch 26 formed on the circumferential surface of the disc 21 corresponding to the pattern plate 34 at a position shifted by 90 degrees, and this signals the motor 14 to stop rotating in the opposite direction. The new pattern plate 34 remains at the optical path position.

Therefore, the next time the lamp 11 lights up,
The player will shoot at the character image corresponding to the character pattern 38 on the new pattern board 34. Therefore, if this new character pattern is different from the previous one, the game will be aimed at different targets one after another each time it hits and explodes, increasing the enjoyment of the game.

The above description is one embodiment of the present invention, and
Various modifications are possible as described below.

Although it has been explained that the character statue explodes on the third hit, this is just a game setting and can be changed in various ways.

As the projection pattern projected as an image onto the screen 2, two patterns are used on the pattern plate 34 as a character pattern 38 and an explosion pattern 39. A pattern device is constructed by rotatably mounting the pattern plate 34 on the pattern support plate 32 via a spring 37, and includes a character pattern 38 and an explosion pattern 39.
However, the number of patterns may be three or more.

The pattern device described above is mounted on four second gears configured as planetary gears 29, but instead of configuring the second gears as planetary gears, one The pattern device may be mounted on the two second gears. In this case, the character pattern cannot be converted to another type of different character pattern, but by switching the pattern plate 34, the character pattern 38 and the explosion pattern 3 can be changed.
9 can be converted, and a rotating projection image can be obtained on the screen 2 by rotating (rotating) the second gear, which is the same as in the above embodiment.

A micro switch 27 is used to detect the position of the disk 21 as a gear support plate, and the pattern plate 34 is
Although a photo switch 51 is used for position detection, the detection elements are not limited to this combination. They may be used in reverse, or the same one may be used. Furthermore, if the tongue piece 32a of the support plate is set to always pass through the photo switch at the start of the game, one switch can serve both purposes. Furthermore, although the pattern switching device is composed of a solenoid 42, a deflection lever 44, a spring rod 47, and an action rod 48,
The pattern may also be switched by directly locking the solenoid to the action rod.

The pattern moving means is composed of the disk 21, the one-way clutch 18, and the micro switch 27, but is not limited thereto. Any device may be used as long as it can be moved to a position where light can pass through.

As described above, according to the present invention, one gear (sun gear 22) meshes with another gear (planetary gear 22).
9) Projection pattern (character pattern 3)
8. By using the explosion pattern 39), the projection pattern can be rotated during projection, so a rotating character image can be obtained on the screen, allowing you to enjoy a game with more variety than ever before. .
