に光源（例えば電燈）を配列して埋込んである。 Structurally, light sources (for example, electric lights) are arranged and embedded in the radial direction on the inner surface of one of the collar plates 1b1 .
４は前記投光器３の光の束を受光する受光器で
他方の鍔板１b2の光の束の投光される箇所に設け
られている。 Reference numeral 4 denotes a light receiver for receiving the beam of light from the light projector 3, and is provided at a portion of the other flange plate 1b2 where the beam of light is projected.
構造的には通常市販のダイオードアレイを用い
線状に投光される光の束を受光できるように細長
い形状に配列されている。 Structurally, commercially available diode arrays are usually used and arranged in an elongated shape so that they can receive a bundle of linearly projected light.
受光器４にはカウンターが内蔵され、受光器４
で受光した光が遮ぎられる数をカウントするよう
になつている。この機構は例えば光が１回遮ぎら
れる毎に１つのパルスが発生する機構となつてい
ればこのパルス数をカウントすることにより光を
遮ぎる回数がカウントされる。 The receiver 4 has a built-in counter.
It is designed to count the number of times the received light is blocked. For example, if this mechanism is such that one pulse is generated each time the light is interrupted, the number of times the light is interrupted can be counted by counting the number of pulses.
この光を遮ぎる回数Ｎ、ケーブル巻回数ｍ、ケ
ーブルの段数ｎ（ケーブルはnn段まで巻かれてい

ーブル長さが表示されるのでこれを直読すればケ
ーブル長が判る。 The number of times N to block this light, the number of cable windings m, the number of cable stages n (the cable is wound up to n stages), the outer diameter D of the cable drum 1a, and the outer diameter d of the cable 2 to be wound are memorized and analyzed. When inputted into the device 5, the cable length calculated by the following formula is displayed on the display section of the device, and the cable length can be determined by directly reading this.

る。 L= on 〓 n=1 π{(D+d(2n-1)} {N-(n-1)m} In other words, as clarified in the NHK Computer Course, etc., if you input the necessary data, the specified Devices (memory analysis processing devices) that calculate and display the results (including printers) are widely used in industry, and the present invention is equipped with this memory analysis processing device to decipher cable lengths. It is.
上記本考案のドラムに於て使用される投光器及
び受光器の電源は通常の電池、交流電源いづれで
もよいが、後者の場合には電源コードはドラムの
軸附近に設ければよい。 The power source for the projector and light receiver used in the drum of the present invention may be either an ordinary battery or an AC power source; in the latter case, the power cord may be provided near the axis of the drum.
ここで投光される光はケーブルドラムの内側半
径方向に線状に投光されるので、ケーブルがドラ
ムの胴に巻き付けられる毎に光を遮ぎるので、こ
の回数をカウントすることは、前述したような解
析装置５により、忽ち解析され、ケーブル長を表
示部に表示するので、直ちにケーブル長を判読す
ることが可能である。 The light projected here is projected linearly in the inner radial direction of the cable drum, so each time the cable is wrapped around the drum body, the light is blocked, so counting this number of times is necessary as described above. Since the cable length is immediately analyzed by such an analysis device 5 and the cable length is displayed on the display section, it is possible to immediately read the cable length.
以上述べた如く本考案によればケーブルドラム
に簡単な光電機構を設けるだけでケーブルドラム
に巻かれているケーブル長が判読でき工事現場で
は有効である。 As described above, according to the present invention, the length of the cable wound around the cable drum can be read by simply providing the cable drum with a simple photoelectric mechanism, which is effective at construction sites.
