ABSTRACT:
In an image pickup apparatus having an openable and closable shutter mechanism to protect an image pickup lens portion of a ultra-small and light-weight video camera, the shutter mechanism is composed of a drive mechanism34including an output shaft rotated by a motor36through a deceleration mechanism, a cam plate24engaged with the output shaft of the drive mechanism34to be rotated through a shaft mechanism coaxial with the output shaft, a shutter plate23engaged with a cam groove27of the cam plate24to be slidably lowered and elevated in the longitudinal direction of a video camera body portion to open and close the front surface of the image pickup lens portion and a clutch mechanism provided in the drive mechanism34to isolate a drive transmission system of the output shaft and the motor36when external force stronger than predetermined external force is applied to the shutter plate23which is being opened and closed. In the ultra-small micro MV video camera, the shutter mechanism to protect the image pickup lens portion can be miniaturized, the shutter mechanism can be avoided from being broken and the highly-precise shutter mechanism can be obtained by simple and easy assembly.
