たピント調整機構。 The optical axis is brought into contact with the sliding member, which is attached to the main plate so that its rotational position can be adjusted and is equipped with a cam for feeding out the lens, and the cam protrusion, which is rotated via a drive gear and engages with the cam. In a lens extending mechanism that includes a drive ring that moves forward and backward along the optical axis, and a lens barrel that is supported by the drive ring and guided to move along the optical axis, when fine focus adjustment is performed, the lens barrel moves along the optical axis. A focus adjustment mechanism that drives the lens barrel for focus adjustment by adjusting only the rotational position of a feeding member.
