Claims (1)
状記録材に光を照射する発光素子と、 ロール状記録材からの乱反射光を受光する受光
素子とを具備して構成され、 受光素子を、ロール状記録材からの全反射光軸
上と異なる位置に設けたことを特徴とするロール
状記録材の残量標識検知装置。[Scope of Claim for Utility Model Registration] A light-emitting element that irradiates light onto a roll-shaped recording material on which a remaining amount indicator made of a light absorber is formed, and a light-receiving element that receives diffusely reflected light from the roll-shaped recording material. What is claimed is: 1. A remaining amount indicator detection device for a roll-shaped recording material, characterized in that the light-receiving element is provided at a position different from the optical axis of total reflection from the roll-shaped recording material.
