ルムが巻れたロールの表面に向けて投光する投光
器と、ロールの表面で反射された光を受光して、
その光の強さに対応した電気信号に変換する受光
器と、受光器からの電気信号を増巾する増巾器と
、予じめ決められた基準電圧を設定する設定器と
、前記増巾器と設定器の出力を比較し、同一もし
くは増巾器の出力が設定器の出力より大きくなつ
たとき、ペースタ信号を発生する比較器とを設け
たことを特徴とするフイルラ用印刷機のオートペ
ースタ装置におけるフイルムの巻尻検出装置。 A projector is supported by the arm of the autopaster and emits light onto the surface of the roll on which the film is wound, and receives the light reflected from the surface of the roll.
a light receiver that converts the light intensity into an electrical signal corresponding to the intensity of the light; an amplifier that amplifies the electrical signal from the light receiver; a setting device that sets a predetermined reference voltage; and a comparator that compares the output of the amplifier and the setting device and generates a paster signal when the output of the amplifier is equal or larger than the output of the setting device. A film end detection device in a paster device.
