の課題があった。[Problems to be Solved by the Invention] However, if the conventional cooling fan device (rotating device) does not rotate normally but rotates abnormally, there is a risk that the safety of the electronic device cannot be ensured. Therefore, when it is attempted to provide a detection means for detecting abnormal rotation in a rotating device, there are various problems such as the device becomes expensive and complicated, or small electronic devices may not even have the space to provide the detection means.

It is an object of the present invention to provide a rotating device that is inexpensive and simple, and is equipped with a rotation abnormality detection means that is not subject to space constraints.
（課題を解決するための手段）
本発明の回転機器は、回転体の一部に反射体を設けると
共に該回転体の回転に同期して上記反射体に光を照射す
る光源を設けて、回転する上記回転体の反射体が定位置
で上記光源の照射光を反射させるようにして構成された
ものである。(Means for Solving the Problems) A rotating device of the present invention is provided with a reflector on a part of a rotating body and a light source that irradiates the reflector with light in synchronization with the rotation of the rotating body. The reflector of the rotating body is configured to reflect the irradiated light from the light source at a fixed position.
本発明の回転機器によれば、作動中に光源が回転体の回
転速度に同期した光を照射すると、回転体の反射体は常
に定位置にあって、その定位置において光を反射する。According to the rotating device of the present invention, when the light source emits light synchronized with the rotational speed of the rotating body during operation, the reflector of the rotating body is always in a fixed position and reflects the light at that fixed position.
以下、第１図に示す実施例に基づいて従来と同一または
相当部分には同一符号を付してその説明を省略し、本発
明の特徴を中心に説明する。Hereinafter, based on the embodiment shown in FIG. 1, parts that are the same as or equivalent to the conventional ones will be given the same reference numerals, and the description thereof will be omitted, and the features of the present invention will be mainly described.

ァン装置（１）は、第１図に示す如く、回転羽根（ｌ１
）の一部に反射体（４）が設けられていると共に該回転
羽根（１ｌ）の回転に同期して上記反射体へ光を照射す
る光源（５）を設けて構成されている。The electronic device (2) shown in FIG. 1 has the same configuration as the electronic device (1) shown in FIG. 2, and includes the rotating device (cooling fan device) (l) of this embodiment. As shown in FIG. 1, the cooling fan device (1) of this embodiment has rotating blades (l1
) is provided with a reflector (4) and a light source (5) that irradiates light to the reflector in synchronization with the rotation of the rotary blade (1l).
而して、本実施例における上記反射体（４）は、上記回
転羽根（１ｌ）の一枚に光を反射し易い塗料が塗布され
た塗料膜によって形成されており、また、上記光源（５
）は、放電サイクル５０Ｈｚの蛍光灯によって構成され
ている。The reflector (4) in this embodiment is formed of a paint film in which a paint that easily reflects light is applied to one of the rotary blades (1l), and the light source (5)
) is composed of fluorescent lamps with a discharge cycle of 50 Hz.
また、上記回転羽根（１ｌ）は、１秒間に５０回転する
ように回転速度が設定されており、上記光源（５）であ
る蛍光灯は上記回転羽根（１１）の回転速度に同期した
サイクルで光を照射するように構成されている。Further, the rotational speed of the rotating blade (1l) is set to rotate 50 times per second, and the fluorescent lamp that is the light source (5) has a cycle synchronized with the rotational speed of the rotating blade (11). It is configured to emit light.
次に動作について説明すると、電子機器（２）の電源を

源（５）である蛍光灯が回転羽根（１ｌ）の回転に同期
して１秒間に５０回光を照射する。Next, the operation will be described. When the electronic device (2) is powered on, the electronic device (2) and the cooling fan device (1) operate as in the conventional case. At this time, the cooling fan device (1
) rotating blade (11) rotates 50 times per second, while a fluorescent lamp serving as a light source (5) irradiates light 50 times per second in synchronization with the rotation of the rotating blade (1l).
そのため、回転羽根（１１）が正しい回転数（１秒回に
５０回転）で作動しているときには、光源（５）である
蛍光灯の放電サイクル５０Ｈｚと同期して反射体（４）
に光が照射されることになって、回転羽根（１１）が回
転しているにも拘らず、反射体（４）がある一定の位置
に停止しているかの如く認識される。Therefore, when the rotary blade (11) is operating at the correct rotation speed (50 rotations per second), the reflector (4) synchronizes with the 50Hz discharge cycle of the fluorescent lamp that is the light source (5).
As a result, the reflector (4) is recognized as if it were stopped at a certain position even though the rotary blade (11) is rotating.
ところが、仮に回転羽根（１１）が正しい回転数から外
れて作動するようになると、回転羽根（１ｌ）の回転数

に見掛け上停止していた反射体（４）による反射光の位
置が一定せずに乱れ、あるいは定常的な回転数異常にな
ると反射体（４）の見掛け上の停止位置が正常回転時の
見掛け停止位置からシフトするため、観測する者は回転
異常が発生したことを視覚的に認識することができる。However, if the rotating blade (11) were to operate at a rotation speed that deviated from the correct rotation speed, the rotation speed of the rotating blade (1l) would no longer be synchronized with the radiation cycle of the fluorescent lamp, and the reflection, which had apparently stopped during normal rotation, would become unsynchronized. If the position of the reflected light from the body (4) is not constant and is disturbed, or if there is a steady rotational speed abnormality, the apparent stop position of the reflector (4) will shift from the apparent stop position during normal rotation, so observation will be difficult. The operator can visually recognize that an abnormal rotation has occurred.
即ち、本実施例の冷却ファン装置（１）の回転異常は視
覚的に容易に認識することができ、その検出手段は安価
且つ単純であり、スペース上の制約もない。That is, abnormal rotation of the cooling fan device (1) of this embodiment can be easily recognized visually, and the detection means is inexpensive and simple, and there is no space restriction.

Although only the one using paint has been described, the reflector (4) in the present invention is not limited thereto, and may be anything that easily reflects light, such as a fluorescent sticker. Further, in the above embodiment, only a fluorescent lamp was described as the light source (5), but the light source (5) in the present invention is not limited to this.
