Description

上記課題を解決するために、本発明は、粉体を収容する粉体収容部と、前記粉体収容部に設けられた可撓性を有する可撓性部材と、前記可撓性部材を押圧して該可撓性部材を撓ます押圧部材と、前記押圧部材により前記可撓性部材を撓ませる動作を行うことで得られる所定の情報に基づいて、前記粉体収容部に収容された粉体の量を検知する粉体量検知手段とを備えた粉体量検知装置において、前記押圧部材が前記可撓性部材を押圧し該可撓性部材の撓みが大きくなるにしたがって、前記押圧部材に設けられた接触部と、該接触部と接触する前記可撓性部材に設けられた被接触部との接触面積が大きくなるように構成したことを特徴とする。
In order to solve the above-described problems, the present invention provides a powder container that contains powder, a flexible member that is provided in the powder container , and presses the flexible member. Then, based on the pressing member that bends the flexible member and the predetermined information obtained by performing the operation of bending the flexible member by the pressing member, In a powder amount detection device comprising a powder amount detection means for detecting a body amount, the pressing member presses the flexible member, and the bending of the flexible member increases as the pressing member increases. The contact area between the contact portion provided on the flexible member and the contacted portion provided on the flexible member in contact with the contact portion is configured to be large.
