Abstract

PURPOSE: To make a screen brighter without increasing the capacity of a battery by determining a focal length of a convex lens so that the inverted image of the light source is formed on an operator's eye and disposing a transmission plate with fine irregularity and red light absorptivity in the operator side of the convex lens. CONSTITUTION: Light of an electric bulb 5 passes through a film display 4 and a convex lens 6 and arrives at player's eye, then the focal distance of the convex lens 6 is determined so as to focus the inverted image of electric bulb 5. By the special feature of the toy, player cannot always fix on the constant position. So that, the transparent plate 7 with fine irregularity is set up. Light is refracted to deflect it's course a little and arrive at the positions 8x and 8y. Therefore, the position of player has a latitude from 8x to 8y including the player's position 8.

Description

[Detailed description of the invention] 【Technical field】

The present invention relates to a toy that resembles the driver's seat of an automobile.

[Prior art]

2. Description of the Related Art Toys in which the light from a light source projects a silhouette on an emulsion translucent plate through a screen provided in front of the light source are well known. The screen is dark because it is powered by batteries.

【the purpose】

Brighten the screen without increasing battery capacity.

Embodiment 1 In FIG. 1, a translucent image 4 is provided on a film 3 that rotates around a shaft 2 provided inside a drive game toy 1. 5 is a light bulb. Reference numeral 6 denotes a sawtooth convex lens, which is inclined so that its upper part approaches the light source side and its lower part approaches the operator side. The transparent plate 7 is made of a red light absorbing material, and one surface thereof is provided with fine irregularities. 7 absorbs a portion of the red light out of the total light emitted by the light bulb, improving the excessive red in the spectrum that is the fate of light bulbs, and also absorbs a portion of the indoor light (part of the red light). This allows you to darken the screen and reduce clouding of the screen due to indoor light. FIG. 2 is a diagram illustrating the principle of the present invention, and for convenience of explanation, the lens is depicted as an ordinary convex lens without a sawtooth shape. The focal length of the lens 6 is determined so that the light emitted from the light source bulb 5 passes through the film image 4, passes through the convex lens 6, reaches the operator's eye 8, and forms an inverted image 5b of the bulb 5. 0 For convenience. Although the eye 8 and the image 5b are drawn separated, in reality, the eye 8 and the image 5b overlap at the same position. The action of the convex lens 6 has been described above in FIG. As long as the operator's eyes are at position 8, there is no doubt that all transmitted light will effectively reach the eyes. However, due to the nature of the toy, it cannot be assumed that the operator will always sit in a fixed position, so as shown in FIG. 3, a transparent plate 7 with minute irregularities is provided. When enlarged, it looks like Figure 4. The light is refracted and its path is slightly biased, reaching the 8x and 8y positions. Therefore, the operator's position has a tolerance that allows a range of 8x and 8y, including 8. If tolerance is not considered too seriously, the uneven cross section may be irregular. In both the present invention and the known ones, the images are shadow pictures. That is, the light emitted from the light source 5 passes through the film image 4 and creates a shadow at the position 6. This principle has been used since ancient times as a ``rotary lantern.''
The cutout part of the rotating picture casts light onto the paper surrounding it. In a known drive game toy, an emulsion translucent plate is provided at position 6 to project the shadow of the film image. There, the light is diffusely reflected,
Some of it goes out of the toy and some of it goes back into the toy. The light that goes outside is also scattered aimlessly, so the light is also scattered to places where the operator is not present. If you reduce the emulsion and make it nearly transparent, in that case only the center of the screen will be bright, and the light from the periphery (D in Figure 5) will not reach your eyes, and the emulsion will reflect room light and make the screen white. There are also some drawbacks that make it cloudy. For the operator's eyes within a certain latitude, the present invention
It adjusts the traveling direction of light, and there is no need to emulsify it. By designing the cross-sectional shape of the uneven plate 7 (FIG. 4), light can be sent within a certain range.

[Embodiment 2] In the above, the basic theory was described in FIG. 2, and the embodiment in which tolerance was provided was described in FIG. This is the basics. However, at the cost of effectiveness, a design in which the image of the light bulb is focused further away than the position of the pilot's eyes does not mean that spurious results cannot be obtained.For example, as shown in Figure 6, The light bulb image 5b may be formed behind the driver, or may be formed in front of the operator as shown in FIG. Further, it may be provided so that a virtual image of the light source is generated in front of the operator (on the light source side). In carrying out the invention, a second lens is used instead of a sawtooth lens.
An ordinary convex lens as shown in the figure may be used. Also, common to ordinary lenses and serrated lenses, the concave-convex plate 7 and the lens are combined into one
One side of the lens may have fine irregularities, or the lens surface may be non-smooth. The image film may be of any shape, such as cylindrical, disc, or circulating film, and the degree of red light absorption is set so that green light and red light are balanced. The image may be an image that is not related to a car, in which case a steering wheel is not required.
A still image may be used.

【effect】

Light reaches the operator's eyes effectively, resulting in a bright, non-cloudy screen.

Claims (1)

[Claims] 1. In a driving game toy equipped with a steering wheel and a video screen to resemble the driver's seat of a car, the light emitted from the light source passes through a transparent rotating screen provided in front of the light source, and further includes a convex lens. The focal length of the convex lens is determined so that the light passes through the pilot's eyes and forms an inverted image of the light source, and on the operator's side of the convex lens there is a translucent plate with fine irregularities and red light absorbing properties. A driving game toy in which the convex lens has a serrated cross section and is slanted so that the upper part approaches the light source and the lower part approaches the operator side. 2. The drive game toy according to claim 1, wherein an inverted image of the light source appears in front of or behind the operator, or a virtual image of the light source appears in front of the operator.
