本発明は部品数が少く、組立の簡単な光によるパルス発
信器に関し、特に光導入口と絞りを一体構造としたパル
ス発信器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical pulse oscillator that has a small number of parts and is easy to assemble, and particularly relates to a pulse oscillator in which a light inlet and a diaphragm are integrally constructed.
従来、発光体と受光体とを対向させ、その間に回転スリ
ット盤を設けたパルス発信器は、受光体の光導入口が大
きかったためマスク効果がなく、パルスの立上り、立下
りの位相位置が明確とならず良いパルスが得られなく、
ミスカウントが多かった。Conventionally, pulse transmitters that had a light emitter and a photoreceptor facing each other with a rotating slit disk in between had no masking effect because the light inlet of the photoreceptor was large, and the phase positions of the rise and fall of the pulse were clear. and you cannot get a good pulse.
There were many miscounts.
そこで、光導入口の上面部に光導入口とは別体のマスク
を載置して光導入口を絞って上述の欠点を解決しようと

に別体のマスクを６９けた（〕のでは、部品数が多くな
り、加］−１相）′ノの二１稈ｂイの分だＬ゛ｊ多く、
それだけ高価となるもので゛ある。Therefore, a method has been developed in which a mask separate from the light inlet is placed on the upper surface of the light inlet to narrow down the light inlet to solve the above-mentioned drawbacks. In this way, with 69 digits of separate masks (), the number of parts is large, and the number of parts is large for the 21st culm b of (+]-1 phase)'.
That's how expensive it is.
その上、絹☆の際に発光体と受光体の中心線にマスクを
取付（プるための位置決めも勤しいしのであった。Moreover, it was difficult to position the mask to attach (pull) the center line between the light emitter and the photoreceptor during the silk ☆ process.
したがって本発明はミズカウン１〜の少い、７１１Ｉ

１６が形成されている。Inside this casing 2, two light emitting bodies 5.5 and two light receiving bodies 6.6 are inserted and fixed by means of a seven-piece fitting 7.7 made of epoxy resin or the like. Each of the light emitters 5.5 and photoreceptors 6.6 (opposing each other, the latter is inside the lid 4 and the latter is inside the main body 3)
It is placed at an angle of about 27 degrees from the center of Kensight 2. As the light emitter 5, a light emitting diode is used, and as the photoreceptor 6, a t-t-run sister is used. The main body 3 constituting the casing 2 has an upwardly opened cup shape consisting of a bottom surface and a circumferential side wall surface, and has a photoreceptor insertion hole 10.6 for receiving a photoreceptor 6.6 at a predetermined position. 40 is formed, and a boss 10 having a through hole 9 into which an input shaft 8 connected to an output shaft of the flow rate 4, etc. is inserted is formed in the center part, and a boss 10 is further formed in the peripheral part for inserting a photoreceptor. Hole 40. Hole 1 for inserting an appropriate number of pulse transmitter fixing rods, preferably 3.
1 has been formed. 1 between the upper part of the circumferential side wall surface of the main body 3
One part is formed with a plurality of relatively small grooves 12 and slightly larger grooves 13.13 arranged symmetrically. In the illustrated embodiment, four small fM 12 are formed, and these are for giving elasticity to the fitting part of the main body 3 when the lid 4 is fitted into the main body 3, and Two grooves 13.13 are formed, and these grooves are engaged with the two engagement opening pieces 14.14 formed on the container 4. Furthermore, in order to ensure the fitting between M4 and main body 3, a circumferential groove 15 is formed near the upper end of the inner circumference of the circumferential side wall surface of main body 3, and an annular projection 16 formed on the outer circumference of M4 is formed. The unevenness is engaged with the surface. The lid 4 is composed of a top surface of a circumferential side wall surface that is open downward to correspond to the circumferential side wall surface of the main body 3. A light emitting body insertion hole 17.17 is formed at a position corresponding to the light emitting body 5.5, and a bearing part 18 is formed in the center to receive the input shaft 8 extending from the through hole 9 of the main body 3. is formed. This light 4
On the circumferential side wall surface of the main body 3, there are formed engagement opening pieces 14.14 corresponding to the tops 13.13 of the main body 3 and an annular projection 16, as shown in (e) above.
