ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of Art
This invention relates to a structure of a display device for switching a display content without using a display by a matrix array of a luminescent picture element, a display switching method, a structure of a target game apparatus using the display device as an airframe, and a target hit display method.
2. Related Art
Heretofore, there has been known a method of changing a display content, in which a luminescent picture element is placed into a matrix array to switching emission/quenching per a picture element, as a TV screen or a Liquid Crystal Display screen, changing brightness of luminescence, forming a predetermined pattern as an aggregate of a picture element and changing the pattern. Besides, as a display method which does not use a display by a matrix array of a luminescent picture element, there is a known method, as a dial display for a timepiece, for rotatably fixing, at one side portion, a plurality of plates having figures or numbers printed on both surfaces thereof so that the plates can be opened sequentially as opening pages of a book. There is another method of feeding a belt-like sheet on which display content is printed thereon from one side to the other, like a destination display panel for a shuttle bus.
The former method in which a matrix array of luminescent picture element is used requires a high technique for picture element array and apparently needs much larger number of picture elements, with the indispensable result of a high cost. Further, since it requires an extremely high Integration of circuit, it inevitably becomes fragile against vibration, shock, etc. The latter method which does not has a matrix array of luminescent picture element has mechanical movement portions and, therefore, results in large-sizing and generation of failure.
SUMMARY OF THE INVENTION
It is, there fore , a n object of the present invention to solve the problems inherent to the known methods and devices and to provide a display device of and method for changing a display content which has properties that it is inexpensive and of a compact structure as well as vibration and shock resistance and t o provide a target game apparatus utilizing the properties of the display device described above and a target hit display method for displaying hitting of a target.
In order to meet with the requirements of achieving the objects of the present invention, according to one aspect of the present invention as recited in claim
1
, there is provided a light-emitting display device comprising: a forward transparent plate having a light scattering portion for a predetermined pattern relative to a surface direction thereof, a backward transparent plate having a light scattering portion for a pattern relative to a surface direction thereof and disposed at the back of the forward transparent plate in the surface direction of the forward transparent plate, the pattern of the light scattering portion of the backward transparent plate being different from the pattern of the light scattering portion of the forward transparent plate, a light source for the forward transparent plate for supplying incidence of light into the forward transparent plate from an end surface of the forward transparent plate, a light source for the backward transparent plate for supplying incidence of light into the backward transparent plate from an end surface of the backward transparent plate, and switching means for switching emitting/quenching of the light source for the backward transparent plate. In the structure described above, by simply switching the light source of the backward transparent plate from a quenching state to an emitting state, a display seen from a forward direction of the forward transparent plate can be immediately switched from a pattern of a light scattering portion of the forward transparent plate to a display of a synthesized pattern of the pattern in the light scattering portion of the forward transparent plate and the pattern in the light scattering portion of the backward transparent plate. In addition, the structure is relatively simply and has no mechanical portion of operation and, therefore, the structure is of shock/vibration-resistive so that an inexpensive device can be achieved with less failure. It should be noted that as well as switching from quenching of the light source for the backward transparent plate to emitting of the light source, the light source of the forward transparent plate can be switched from emission to quenching so that a design on the light scattering portion of the forward transparent plate can be displayed in a relatively weak (or tender) manner. The light scattering portion can be formed by selectively applying a coating material on the transparent plate, roughening the transparent surface by using a file and the like, or adapting or fitting another material into the transparent plate, or employing any other suitable methods.
In another aspect of the invention, at least one of the light scattering portion of the forward transparent plate and the light scattering portion of the backward transparent plate is formed by applying a coating material on a surface of the transparent plate. This permits provision of a desired light-emitting display device which can be switched simply and inexpensively.
In another aspect of the invention, a photo-adsorption member is disposed at the back of the backward transparent plate. This can prevent or restrict light scattering at the other portions than the pattern portion, which light scattering is caused by flaws on the forward and backward transparent plates, foreign particles, transparency of the material per se and so forth, so that the necessary pattern can be emerged to aid recognizing the display.
In another aspect of the invention, there is provided a light-emitting display device in which a translucent is provided between the forward transparent plate and the backward transparent plate. This will prevent the pattern of the backward transparent plate from being visible or reconized at the time of quenching of the light source of the backward transparent plate so that the pattern of the forward transparent plate is emerged to aid seeing soley and seperately the display of the forward transparent plate.
In another aspect of the invention, the pattern of the light scattering portion of the backward transparent plate is a cracking pattern. This permits to provide a fancy impression as if the both transparent plates are cracked, at the time when the backward transparent plate is switched from a quenching state to an emmitting (luminescent) state.
In a further aspect of the invention, a shock sensor is disposed for detecting a shock against the forward transparent plate so that when a shock is detected by the shock sensor, the light source for the backward transparent plate is switched from a quenching state to an emitting state. This will permit dramatic display of the posture of a change due to the shock received by the display portion.
In another aspect of the invention, a plurality of backward transparent plates are provided relative to the forward transparent plate and the switching means designed to serve to switch the light source of a corresponding backward transparent plate from a quenching state to an emitting state with respect to a shock-impacted portion of the forward transparent plate. This permits to provide an international and dramatic display representing a posture of a change in response to the shock received by the display portion and additionally displaying a location of the portion which receives the shock.
In another aspect of the invention, a plurality of forward transparent plates are provided and a backward transparent plate is provided corresponding to each of the forward transparent plates and the switching means is designed to serve the light source for the backward transparent plate which corresponds to the forward transparent plate receiving the shock to switch from a quenching states to an emitting state. This structure can restrict to transmi
