Claims

[Scope of utility model registration request]

A lens barrel unit consisting of a plurality of lens barrels including lenses with different focal lengths, and each of the lens barrels is brought onto the optical axis of the camera and positioned, and the lens barrel unit is moved along the optical axis. In a focus switching camera configured to be able to switch each of the lens barrels, an aperture plate to be shared by the plurality of lens barrels is disposed, and the aperture plate is provided in common with the plurality of lens barrels. The plate and the lens barrel unit are slidably mounted on a guide shaft inclined at a predetermined angle from a direction orthogonal to the optical axis, and each lens mirror is brought onto the optical axis via the guide shaft. A lens barrel support structure for a focus switching camera in which the imaging positions on the optical axis of the barrel coincide.
