SHUTTER UNIT AND IMAGING APPARATUS

PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of stably absorbing an impact, even when the impact when driving a shutter is caused, while holding a shutter unit.SOLUTION: The imaging apparatus includes the shutter which controls subject light to an imaging element, a holding frame which holds the shutter, an annular elastic member which absorbs the impact caused when driving the shutter, a fastening member which is engaged with the inner diameter part of the annular elastic member and fastens the holding frame to an imaging apparatus body, a first body-side fastened part which is provided in the imaging apparatus body and fastened by the fastening member, and a first holding frame-side fastened part which is provided in the holding frame and fastened by the fastening member. A through-hole having a space which is brought into press-contact with the outer diameter of the annular elastic member, so that the annular elastic member can be compressed and deformed, when the impact is caused is formed in the first holding frame-side fastened part.SELECTED DRAWING: Figure 4 【課題】シャッターユニットを保持しつつ、シャッター駆動時の衝撃が生じた場合であっても、安定して衝撃吸収することができる撮像装置を提供する。【解決手段】撮像素子への被写体光を制御するシャッターと、シャッターを保持する保持枠と、シャッターの駆動時に発生する衝撃を吸収する環状弾性部材と、環状弾性部材の内径部と係合し、撮像装置本体に保持枠を締結する締結部材と、撮像装置本体に設けられ、締結部材によって締結される第１本体側被締結部と、保持枠に設けられ、締結部材によって締結される第１保持枠側被締結部と、を有し、第１保持枠側被締結部は、環状弾性部材の外径と圧接し、衝撃が生じた際に環状弾性部材が圧縮変形できる空間を有する貫通孔を形成している。【選択図】図４
