摘要： A lens barrel of the present invention includes: a fixing frame having a plurality of cam grooves that are formed an inner circumferential surface of the fixing frame and also having a protrusion provided between any adjacent two of the cam grooves among a plurality of the cam grooves; and a drive frame having cam followers that are provided to an outer circumferential surface of drive frame, are engaged with the cam grooves, and are movable along the cam grooves. With this configuration, when an external force is applied to the drive frame, an end portion of the drive frame comes into contact with the protrusion to prevent the cam followers from coming out of the cam grooves.

摘要： A lens barrel includes a fixing frame provided with cam grooves formed in an inner circumferential surface of the fixing frame, and a drive frame provided with cam followers formed on an outer circumferential surface of the drive frame and a plurality of engaging teeth to the outer circumferential surface of the drive frame, located on substantially the same circumference as the cam followers. With the drive frame incorporated in the fixing frame, the cam followers are fitted in the cam grooves, drive force is transmitted via the engaging teeth, and the drive frame can move relative to the fixing frame in the optical axis direction of a lens as the cam followers move along the cam grooves. In this lens barrel, cam followers are less likely to come out of the cam grooves.

摘要： A lens barrel of the present invention includes a fixing frame 100 provided with cam grooves 103-105 formed in an inner circumferential surface of the fixing frame, and a drive frame 200 provided with cam followers 201-203 formed on an outer circumferential surface of the drive frame and a plurality of engaging teeth 200a provided to the outer circumferential surface of the drive frame so as to be located on substantially the same circumference as the cam followers 201-203. The drive frame 200 is adapted such that, with the drive frame incorporated in the fixing frame 100, the cam followers 201-203 are fitted in the cam grooves 103-105, drive force is transmitted via the engaging teeth 200a, and the drive frame 200 can move relative to the fixing frame 100 in the optical axis direction of a lens as the cam followers 201-203 move along the cam grooves 103-105. According to the present invention, it is possible to provide a lens barrel in which cam followers are less likely to come out of the cam grooves even in the case where a retainer wall cannot be provided within an area where a cam follower about to fall out is received directly by the wall, or in the case where the retainer wall provided within the area where a cam follower is received directly is not sufficient.

摘要： A linear actuator in a simple structure with an excellent S/N characteristic has a movable coil incorporating a pair of magnetic circuits 8a and 8b. The magnetic circuit 8a comprises yokes 6a and 7a, and a magnet 5a of which polarization direction is vertical with regard to a driving direction. The magnetic circuit 8b has the same structure as 8a. As a position detector, a magnetic sensor 10 and a magnetic scale 11 are disposed opposite with each other on a stator side and on a movable element side respetively.
