    • PROBLEM TO BE SOLVED: To provide a lens barrel holder which facilitates attachment/detachment of a lens barrel to/from the holder, surely holds the lens barrel and furthermore, does not apply an excess load to the lens barrel. SOLUTION: The lens barrel holder has: a first holding member 1; a second holding member 2 which is attached to the first holding member in an openable/closable manner, tightens the periphery of the lens barrel and holds the lens barrel with the first holding member; and a tightening mechanism which acts force for tightening the lens barrel on the second holding member. Then, the tightening mechanism has a tightening member 4 having an engagement surface 2c provided in the second holding member and a abutting surface 4a which is provided in the first holding member, moves straight so as to move back and forth with respect to the engagement surface and can be abutted on the engagement surface. At least one of the abutting surface 4a and the engagement surface 2c has inclination to the going straight direction of the tightening member 4. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:为了提供一种便于将镜筒与支架连接/拆卸的透镜镜筒保持器,确保保持透镜镜筒,此外,不会对透镜镜筒施加过多的负载。 透镜筒保持器具有:第一保持构件1; 以可打开/关闭的方式附接到第一保持构件的第二保持构件2,紧固透镜镜筒的周边并且用第一保持构件保持透镜镜筒; 以及紧固机构,其对第二保持部件上的镜筒施加作用力。 然后,紧固机构具有紧固构件4,该紧固构件4具有设置在第二保持构件中的接合面2c,并且设置在第一保持构件中的抵接面4a直线移动以相对于接合面前后移动 并且能够抵接在接合面上。 抵接面4a和接合面2c中的至少一方具有朝向紧固件4的直线方向的倾斜。版权所有(C)2005,JPO&NCIPI
