Description

そのために本発明では、インクを収納するためのインク収納部を有するケース部材と、該ケース部材に支持される一端と、自由端である他端とを有し、前記ケース部材に近づく方向に変位可能な支持部材と、前記一端側の近傍に設けられた発光部と、を有するインクタンクであって、前記支持部材は、前記発光部の近傍に設けられ前記発光部からの光を受光可能で前記支持部材の前記変位に伴い前記発光部に近づいて対向するように変位する受光部と、前記他端側に設けられ前記受光部で受光した光を出射する出射部と、前記受光部で受光した光を前記出射部に導光する導光部と、を有することを特徴とする。 Therefore, the present invention has a case member having an ink storage portion for storing ink, one end supported by the case member, and the other end being a free end, and is displaced in a direction approaching the case member. An ink tank having a support member capable of light emission and a light emitting part provided in the vicinity of the one end side, wherein the support member is provided in the vicinity of the light emitting part and can receive light from the light emitting part. A light receiving portion that is displaced so as to approach and face the light emitting portion with the displacement of the support member, a light emitting portion that is provided on the other end side and emits light received by the light receiving portion, and light received by the light receiving portion. And a light guide part for guiding the emitted light to the emitting part.

Claims
