Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 本発明では、人的要因を排除して客観的に一 定した評価を得ることができ、しかも、ケースやリール を分解または破壊する必要のない帯状物の巻き姿評価方 法を提供することを課題とする。 【解決手段】 リール11から磁気テープ12を繰り出 しつつ磁気テープ12の幅方向の位置変動を長さ方向の 全域に亘って光センサ4により検出し、その検出信号に 基づいてリール11に巻装された磁気テープ12の巻き 面からの巻き崩れの位置および量を信号処理装置5によ り算出し、プリンタ6に表示する。 (57) [Summary] [PROBLEMS] In the present invention, an objectively constant evaluation can be obtained by eliminating human factors, and a winding form of a belt-like object that does not require disassembling or destroying a case or a reel. It is an object to provide an evaluation method. A position change in the width direction of a magnetic tape 12 is detected by an optical sensor 4 over the entire length direction while the magnetic tape 12 is fed out from a reel 11, and wound around the reel 11 based on the detection signal. The position and amount of collapse from the winding surface of the magnetic tape 12 are calculated by the signal processing device 5 and displayed on the printer 6.
