BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention generally relates to an electronic appliance. More specifically, the present invention is directed to an electronic appliance equipped with a pointer whose position can be visually confirmed even in the dark, wherein a plane-shaped light emitting apparatus is arranged on a dial.
2. Background Art
Conventionally, electronic appliances, for instance, electronic watches employing EL (electroluminescent) elements for producing as so-called "back-light (back-surface illuminating light)" are known in the art. FIG. 20 schematically shows one conventional electronic wrist watch. As indicated in this drawing, a dial (face) 1 is arranged by a light emitting apparatus constituted by stacking an EL (electroluminescent) light emitting apparatus 1B behind a transparent film 1 along a light incident direction. The characters
umerals indicative of "hours" are printed on this transparent film 1A. An hour/minute hand shaft 2A is penetrated through an center opening 1C of this dial 1. A minute hand 2B and an hour hand 2C are mounted on this hand shaft 2A in such a manner that these hands 2B and 2C are rotated above the dial 1. In this electronic wrist watch, when the EL light emitting apparatus 1B emits light, the color of this dial 1 is illuminated in the emission color thereof. Accordingly, the characters
umerals indicative of "hours" printed on the dial 1, the minute hand 2B, and the hour hand 2C are illuminated, so that a present time is readable.
In the above-described conventional dial having the above-described light emitting apparatus, since an inorganic EL element is employed as the light emitting apparatus, the color of this face 1 is limited to the emission color of this inorganic EL element during not only turn-ON operation, but also turn-OFF operation. As a result, the conventional electronic wristwatch could not achieve high-grade quality and decorative feelings.
DISCLOSURE OF INVENTION
The present invention has been made to solve the above-explained problem, and therefore, has an object to provide an electronic appliance equipped with a light emitting apparatus, whose dial or face can be designed in various ways and can which can achieve high-grade quality and decorative feelings.
To achieve the above-mentioned object, an electronic appliance equipped with a light emitting apparatus, according to an aspect of the present invention, is comprised of: thereof, on which a character and a pattern are formed; transparent sheet member and having an opening at a position opposite to said opening of the transparent sheet member; having an opening at a position opposite to said opening of the light emitting apparatus; openings of said colored sheet member, said transparent light emitting apparatus, and said transparent sheet member toward an upper portion of said transparent sheet member; and
With employment of the above-described structure, in the electronic appliance of the present invention, when the light emitting apparatus is not driven, since the colored sheet member can be observed through the transparent sheet member and the transparent light emitting apparatus, this colored sheet member can provide high-grade quality and decorative feelings. When the light emitting apparatus is driven, the light emitted from this light emitting apparatus can illuminate the hands through the transparent sheet member.
