従来、時計の照明装置において、特に指針を発光させるものは、例えば実公昭 60−33413号の針照明時計や、実公昭60−42390号の時計の指針照 明装置に開示されている。 前者においては分針及び時針内にランプをそれぞれ配置し、ランプが点灯する と各指針表面部が光るものである。後者は各指針軸の先端部に透明部材からなる エツジライト式の指針が嵌着され、前面ガラスに設けた修正摘み内に収納された 電球からの光が各指針へ導光されるものである。 2. Description of the Related Art Conventionally, among lighting devices for timepieces, those for emitting a pointer are disclosed, for example, in a hand-illuminated timepiece of JP-B-60-33413 and a pointer-illumination device of a watch of JP-B-60-42390. In the former case, lamps are arranged in the minute hand and hour hand respectively, and when the lamp is turned on, the surface of each pointer illuminates. In the latter, an edge light type pointer made of a transparent member is fitted to the tip of each pointer shaft, and the light from the light bulb housed in the correction knob provided on the front glass is guided to each pointer.

前記の指針内にランプを配置した針照明時計においては、指針内にランプを収 納する為の組立てが極めて面倒であり、部品点数が多く指針自体の小型化・薄型 化に支障があった。また、前記エツジライト式指針を備えた指針照明装置におい ては、光源が指針と分離されているので指針自体は小型化・薄型化可能であるが 、光源の配置スペースが必要となり、全体としては大型になるという課題があっ た。 さらに、従来においては光源からの光は指針の前方へ発散するように設定され ているので、文字板上の指標については個別の光源にて照明する必要があった。 本考案の目的は指針の裏面に設けた電界発光灯(以下EL板という)にて文字 板の指標を照明すると共に、指針形状をシルエットの様に現すことにより時刻確 認が容易であり、分解・組立てが極めて容易であって、薄型化・小型化された照 明装置を提供することである。 In the hand-illuminated timepiece in which the lamp is arranged in the pointer, the assembly for storing the lamp in the pointer is extremely troublesome, and the number of parts is large, which hinders downsizing and thinning of the pointer itself. Further, in the pointer illuminator equipped with the edge light type pointer, since the light source is separated from the pointer, the pointer itself can be made smaller and thinner, but a space for arranging the light source is required, and as a whole, it is large. There was a problem of becoming. Further, in the past, since the light from the light source was set to diverge in front of the pointer, it was necessary to illuminate the index on the dial with individual light sources. The purpose of the present invention is to illuminate the index of the dial with an electroluminescent lamp (hereinafter referred to as an EL plate) provided on the back of the pointer and to make the shape of the pointer look like a silhouette for easy time confirmation and disassembly. -It is to provide an illumination device that is extremely easy to assemble and that is thin and compact.

本考案によれば指針の裏面に厚みの薄いEL板を設け、該EL板の発光面上に 拡散部材を設けたので、EL板から発光された光は文字板面を好適に照明できる 。そして、EL板自体の厚みは極めて薄いので、指針にEL板および拡散部材を 重設しても従来に比べてかなり薄く設定でき、時計体の薄型化が達成できた。発 光面の面積を指針形状全体に設定でき、指針が接近した指標を最も明るく照明で きるので、指針の位置関係が明確となり、これによって時刻の確認も容易となる 。部品点数も少なく、指針の取り扱いも簡単である。 According to the present invention, since the thin EL plate is provided on the back surface of the pointer and the diffusing member is provided on the light emitting surface of the EL plate, the light emitted from the EL plate can suitably illuminate the dial surface. Since the EL plate itself is extremely thin, even if the EL plate and the diffusing member are superposed on the pointer, the EL plate can be set to be much thinner than the conventional one, and the timepiece can be made thinner. Since the area of the light emitting surface can be set to the entire pointer shape, and the pointer that the pointer approaches can be illuminated most brightly, the positional relationship of the pointer becomes clear, which makes it easy to check the time. The number of parts is small and the pointer is easy to handle.
