A lens barrel () comprises a drive frame () and a first lens frame (). The first lens frame () has first to third cam followers (to) that are respectively inserted into first to third outer cam grooves (to), and first and second auxiliary pins (and) disposed so as to be able to come into contact with first and second auxiliary grooves (and). When viewed in the Y axis direction, the first and second auxiliary pins (and) are disposed between the first to third cam followers (to) in the peripheral direction. The positions of the first and second auxiliary pins (and) are offset from the positions of the first to third cam followers (to) in the Y axis direction.

Lens barrel

A lens barrel includes a fourth lens, a prism, and a sixth lens. The fourth lens receives a light flux incident along a first optical axis. The prism includes a reflecting surface reflecting the light flux passing through the fourth lens to a direction along a second optical axis intersecting with the first optical axis. The sixth lens receives the light flux reflected by the prism. A second group frame includes an opening portion, a prism retaining frame that is arranged in a more inner position than the opening portion and in which the prism is contained, and a plurality of adhesive pockets arranged on an area around the prism retaining frame and being open to the side of the opening portion. Adhesive agent is filled in the adhesive pockets.

To produce a subject's image on an imager as accurately as possible, a technique that is effectively applicable to the process of assembling an optical system is provided. An imaging device includes: an imager; a plate member, to which the imager is attached; and a holding member configured to hold the plate member. The plate member has a first portion, through which at least one fixing hole has been cut, and a second portion, to which the imager is attached and through which at least one adjusting hole has been cut. The plate member is held by the holding member using a number of fastening members to be introduced through the at least one fixing hole and the at least one adjusting hole. When the first portion is fixed on the holding member, the fastening member that is introduced through the at least one adjusting hole adjusts the relative position of the second portion to the holding member.

Lens barrelincludes a stationary frame, a drive frame, a rotation cam frame, and a first lens frame. The drive frameis supported by the stationary frameto be movable in a Y axis direction along an optical axis of an imaging optical system O and rotatable around the optical axis in response to a drive force. The rotation cam frameis supported by the drive frameto be movable in the Y axis direction relative to the drive framein response to the drive force. The first lens framesupports a first lens group Gincluded in the imaging optical system O, and is supported by the rotation cam frameto be movable in the Y axis direction relative to the rotation cam framein response to the drive force.

A lens position calculator is provided that determines a phase of a driving signal as a reference position of an imaging lens when an output value of a position detection sensor reaches a threshold value. The lens position calculator determines a position obtained by performing addition or subtraction on the reference position read out from a reference position storage as a judgment position, detects an output value of the position detection sensor at a timing in synchronization with the driving signal that drives a driver and at the judgment position, and judges whether the output value of the position detection sensor at the judgment position reaches the threshold value or not, so as to determine the reference position again.

It is an object of the present invention to provide an image blur correcting device having a dimension reduced in any one direction perpendicular to the optical axis of the incident light, and a camera equipped with this device. The image blur correcting deviceincludes a pitching movement frame, a pitching guide mechanism, a yawing guide mechanism, a pitching direction electromagnetic actuator, and a yawing direction electromagnetic actuator. The pitching movement framesupports a third lens group Gfor performing image blur correction. The pitching guide mechanismguides the pitching movement framein the pitching direction. The yawing guide mechanismguides the pitching movement framein the yawing direction. The electromagnetic actuatordrives the pitching movement framein the pitching direction. The electromagnetic actuatordrives the pitching movement framein the yawing direction. The electromagnetic actuatorand the electromagnetic actuatorare provided substantially opposed to each other and with a second optical axis Ainterposed therebetween.

Image blur correcting device and camera

A lens barrelis mounted in a collapsible imaging deviceand includes a third lens frame. The third frameis a lens frame to which correction lenses L, L, Lare mounted and includes a shutter unit, a vibration compensation actuator, a lens frame main body, a focus lens frame, and a focus motor. The focus lens frameis urged against the lens frame main bodytoward the image plane side by means of a focus spring. A motor sectionof the focus motoris arranged in a region interposed between two multilayer printed circuit boardswhen viewed from the image plane side or the object side.
