Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image synthesizing display device that displays an image by superimposing a background and an image. This device is used, for example, in a shooting game machine when displaying a target image on an appropriate background. Conventional technology In a game machine, for example, an image of a torpedo or missile model and an enemy ship model are synthesized using a half mirror, and the torpedo or missile model is moved to a position corresponding to the position of the enemy ship model. 2. Description of the Related Art An image display mechanism that makes a collision appear without causing the collision is known. However, in this device, a mechanism for moving a torpedo or the like is complicated. Due to its complexity, torpedoes cannot be moved at high speed. Also, since torpedoes are models,
The outer shape itself cannot be changed. Problems to be Solved by the Invention The present invention is to solve the problem to provide an image synthesizing display device which can move an image corresponding to a torpedo or the like at a high speed and has a very simple configuration for that purpose. Point. Means for Solving the Problems Means for solving the above problems, that is, the present invention is an image synthesizing display device that displays a background and an image superimposed, a monitor that generates image light, A half mirror placed in front thereof, an optical system for guiding image light from the monitor to the half mirror, and optical path changing means for changing the optical path of the image light with respect to the angle, wherein the optical path changing means is substantially perpendicular to each other. An image synthesizing display device comprising a mirror and a half mirror that can reciprocate and rotate in appropriate ranges around an axis, and wherein the mirror and the half mirror are controlled to rotate simultaneously. Examples Hereinafter, the present invention will be described based on examples. FIG. 1 is a diagram showing a case where an image synthesis display device according to one embodiment is applied to a shooting game device. In the figure, a monitor 1 is provided at a lower right portion of the game device, and a half mirror 2 is provided at an upper left portion of the game device. Behind the half mirror 2, a field 3 as a background and another background 4 are provided. The field 3 is illuminated by a fluorescent lamp 8 placed behind. For example, an image 5 as shown in FIG. 2 is displayed on the monitor 1, and this becomes the image light L in FIG. The image light L passes through a half mirror 6 provided on the front surface of the monitor 1, is reflected by a mirror 7 provided above the game device, and is guided to the half mirror 2. The image light L guided to the half mirror 2 is combined with the field 3 and the background 4 and is visually recognized by the player M as a target image. The player emits light such as infrared light from the gun 9 toward the target image. If the light was emitted exactly towards the target image, the light would be reflected in half mirror 2, mirror 7,
After being reflected by each mirror of the half mirror 6, the light is received by an optical sensor 13 placed at a predetermined position on the substrate 10 as shown in FIG. The optical sensor sends light reception information to a control device (not shown) arranged at an appropriate position in the game device, and based on the information, sends an appropriate light for indicating that the target has been shot down by the control device. Processing such as displaying a ruptured target image on the monitor 1 is performed. As shown in FIG. 4, a plurality (8 in FIG. 4) is provided around an optical sensor 13 for detecting whether or not light hits a target.
And other light sensors 14 are arranged, and when light deviates from the target and is received by any of these light sensors, an appropriate process for indicating that the target has been missed, for example, Processing such as displaying an image in which a bullet (not a target) explodes on the monitor 1 may be performed. In the present embodiment, the half mirror 2 placed in front of the background 4 or the like can reciprocate in an appropriate angle range around an axis 11 (an axis in a direction perpendicular to the paper surface) as indicated by a chain line. Further, as shown in FIG. 3, the mirror 7 can reciprocate in an appropriate angle range as indicated by a chain line about an axis 12 substantially perpendicular to the rotation axis 11 of the half mirror. Due to the rotation of the half mirror 2, the target image projected on the half mirror 2 moves up and down for the player. Also, by the rotation of the mirror 7,
The target image on the half mirror 2 moves right and left. Therefore, by combining the rotation of the half mirror 2 and the mirror 7, the target image on the half mirror 2
And, it can be freely moved in all directions of up, down, left and right in the background 4. By appropriately selecting the rotation speed and the rotation range of each mirror, the movement mode of the target image can be set to any desired state. In this embodiment, the target image is the image light L from the monitor 1.
Made by. The monitor 1 can freely change the screen display content by the control device described above. Also, the control for the change is simple. For example,
Now, it is assumed that the contents displayed on the screen gradually become smaller in a relatively short time, as shown by the chain line in FIG. Then, in response to this, the target image projected on the half mirror 2 in FIG. 1 also becomes smaller in a relatively short time.
This is perceived by the player as a target moving away toward the background 4 in a relatively short time. In the embodiment, the half mirror 2 is rotated about a horizontal axis 11, and the mirror 7 is rotated about an axis 12 substantially perpendicular to the horizontal axis 11. Not limited to this,
The same effect can be obtained even if the half mirror 2 is rotated about a vertical axis (an axis perpendicular to the horizontal axis) and the mirror 7 is rotated about an axis substantially perpendicular to the vertical axis. When the target is to be moved only in one of the horizontal direction and the vertical direction, only one of the half mirror 2 and the mirror 7 may be rotated. In the above embodiment, the target image is moved by changing the optical path of the image light L with respect to the angle using the half mirror 2 or the mirror 7. However, the present invention is not limited thereto, and another rotatable mirror or half mirror may be separately prepared, and the optical path may be changed by these mirrors or the like. Furthermore, a monitor having a large screen size is prepared as the monitor 1, a plurality of (for example, two) moving target images are projected on the screen, and the monitor 1 is arranged on the substrate 10 in a matrix form in opposition to the monitor screen. It is also possible to arrange a plurality of optical sensors described above. The target image on the screen is specified in the control device by an XY (orthogonal) coordinate system, while the individual sensors constituting the matrix-like sensor group are also individually positioned by the XY coordinate system. Has been identified. Therefore, by comparing and comparing the instantaneous coordinate position of the moving target image with the coordinate position of the sensor that has received the light from the gun, it can be determined whether or not the light from the gun has hit the moving target. Effects According to the present invention, the image on the half mirror can be freely moved in all directions, up, down, left, and right, by a combination of the rotation of the half mirror and the rotation of the mirror. In addition, by appropriately selecting the rotation speed and the rotation range of the mirror and the half mirror, it is possible to set an image movement mode to a desired state.
