【発明の詳細な説明】
この発明は、相対移動する２つの物体間で信号を伝達す

従来、この種の信号伝達装置は、相対移動する物体間に
スリップリングとブラシとを介在させて−、信号を伝達

接触部分が犀耗シタりし、信頼性、耐久性に問題があっ
た。Conventionally, this type of signal transmission device generally transmits signals by interposing a slip ring and a brush between relatively moving objects. However, since this type of signal transmission is based on mechanical contact between the slip ring and the brush, contact resistance may become ashes (this may cause noise,
The contact parts were worn out and there were problems with reliability and durability.
これに対し、相対移動する物体間を光によって連絡して

上の配慮を必要とし、量産品で信号伝達を確実に行なう
ためには、まだ技術的に解決すべき問題が多い。In contrast, a method has been proposed in which relatively moving objects are communicated by light and signals are transmitted in a non-contact manner. In this method, in order to reliably transmit signals no matter where the object is in its relative movement, light is emitted uniformly within the movement range, but it must also be able to receive light uniformly. However, in order to achieve uniform light emission or uniform light reception, delicate design considerations are required for the material, shape, etc. of the photoconductive member, and in order to ensure reliable signal transmission in mass-produced products. There are still many technical problems to be solved.
かかる問題に鑑み２本発明の目的とするところは、信号
伝達に液晶を使用することにより、非接触で、かつ精度
良く信号伝達を行なうことにある。In view of such problems, it is an object of the present invention to perform contactless and highly accurate signal transmission by using a liquid crystal for signal transmission.

どの位置でも均一に。According to the present invention, since the brightness of the liquid crystal is detected by a photosensor, signals can be transmitted without contact.
Moreover, since the liquid crystal provided within the range of relative movement displays brightness and darkness depending on the signal to be transmitted, the display is uniform at any position within the range of relative movement.

介して伝達すべき信号を受け、ケーシング３１内の電源
および駆動回路によって、液晶３２に電圧を印加し、液
晶３２の表示向を明暗変化させる。The drawing is a perspective view of one embodiment, and one of the relatively moving objects having a signal source to be transmitted is a rotating body 1, and the other object to which the signal is transmitted is a fixed body 2. The rotating body 1 is provided with a liquid crystal display 3, and this liquid crystal display 3 has a liquid crystal 32 provided around the entire circumference of a casing 31, which is a range of relative movement, with its display surface facing the fixed body 2.
This liquid crystal display 3 receives a signal to be transmitted via a signal line 4 from a signal source (not shown), applies a voltage to the liquid crystal 32 by a power supply and a drive circuit inside a casing 31, and changes the display direction of the liquid crystal 32 to bright or dark. change.
なお、３３は、信号線４をケーシング３１内に導くため
のコネクタである。Note that 33 is a connector for guiding the signal line 4 into the casing 31.
固定体２には、明度検出器５が設けられ、この明度検出
器５は、液晶３２を照明する照明灯６と。The fixed body 2 is provided with a brightness detector 5, and the brightness detector 5 serves as an illumination lamp 6 for illuminating the liquid crystal 32.

。液晶３２は。In this way, when a signal is received from the signal source, the display surface of the liquid crystal 32 becomes dark, and the light received by the photosensor 8 decreases, and when the signal from the signal source disappears, the display direction of the liquid crystal 32 becomes brighter. As a result, the photosensor 8 receives more light, and corresponding signals are output from the signal lines 9. The liquid crystal 32 is.
ケーシング３１の全周にあって、全周が同時に明暗灰化
