    Abstract: The present invention provides a method for fabricating a lens unit in which an inter-barrel member can be fixed with a high degree of accuracy without enlarging the lens barrels and the accuracy of the dimension of the inter-barrel member is not required. The method comprises the steps of: disposing an inter-barrel member 11 in a gap ā€œgā€ defined between a front lens barrel 7 on a subject side in an optical-axis direction x and a rear lens barrel 8 on an imaging surface side in the optical-axis direction x; bringing the inter-barrel member 11 into close contact with one of the front lens barrel 7 and the rear lens barrel 8 in the optical-axis direction x; inserting a resilient member 12 into a space in the optical-axis direction x between the inter-barrel member 11 and the other of the front lens barrel 7 and the rear lens barrel 8; and fixing the front lens barrel 7 and the rear lens barrel 8 integrally with each other to compress the resilient member 12 in the optical-axis direction x.

  • Patent number: RE42783
    Abstract: When an attempt to move a projection lens in a horizontal direction (crosswise) in a state where it is positioned on the upper or lower side is made, it can be moved in the horizontal direction (crosswise) up to a certain range. However, a movement restraining convex area in a vertical movable base finally comes into contact with the corner inclined at an angle of 45 degrees in a fixed base. After this contact, movement in a leftward or rightward direction and an upward or downward direction which are limited directions is limited. Even if a dial and a dial are rotated in the limited directions under the limitation of the movement, they are slipped, thereby making it possible to prevent a force from being forcedly applied to a driving mechanism.
