发明名称 Aperture and focus adjusting device for a camera
摘要 An aperture and focus adjusting device for a camera is provided with only one reversible motor, a first adjusting mechanism, and a second adjusting mechanism. The first adjusting mechanism is rotated by a first member which is connected to the motor, and the second adjusting mechanism is rotated by a second member to which an intermediate rotational member is connected. The intermediate rotational member is in constant mesh and is rotated with the second member, and is engaged with the first member only within a sector of a rotational range of the first member, to rotate together with the first member. One of the first and second mechanisms is a focus adjusting mechanism, and the other is an aperture adjusting mechanism.
