A lens barrel (3) comprises a drive frame (30) and a first lens frame (50). The first lens frame (50) has first to third cam followers (54a to 54c) that are respectively inserted into first to third outer cam grooves (34a to 34c), and first and second auxiliary pins (55a and 55b) disposed so as to be able to come into contact with first and second auxiliary grooves (35a and 35b). When viewed in the Y axis direction, the first and second auxiliary pins (55a and 55b) are disposed between the first to third cam followers (54a to 54c) in the peripheral direction. The positions of the first and second auxiliary pins (55a and 55b) are offset from the positions of the first to third cam followers (54a to 54c) in the Y axis direction.

A signature log storing apparatus includes a signature log list and a certificate list, and registers, in the signature log list, a part of signature information in generated hysteresis signature as a signature record and a part of a user certificate in the certificate list. The signature log storing apparatus further includes a trust point list and validates a signature records registered in the signature log list and registers identification information for identifying a latest signature record out of the validate signature record, evidence information for validating validity of the user certificate for a validated signature record, and a hash value of information derived by connecting the evidence information and the hash value as needed or before the user certificate expires.

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.

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.

Lens barrel 3 includes a stationary frame 20, a drive frame 30, a rotation cam frame 70, and a first lens frame 60. The drive frame 30 is supported by the stationary frame 20 to 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 frame 70 is supported by the drive frame 30 to be movable in the Y axis direction relative to the drive frame 30 in response to the drive force. The first lens frame 60 supports a first lens group G1 included in the imaging optical system O, and is supported by the rotation cam frame 70 to be movable in the Y axis direction relative to the rotation cam frame 70 in response to the drive force.
摘要:
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.

A digital camera includes a first lens group, a second group frame unit, a third lens group, a CCD unit, a lens barrel, and a chassis. The first lens group receives a light flux along a first optical axis. The second group frame unit receives and bends the light flux along a second optical axis after passing through the first lens group. The third lens group receives the bent light flux from the second group frame unit. The CCD unit receives the light flux passing through the third lens group. The lens barrel includes the first lens group, the second group frame unit, the third lens group, and the CCD unit. The chassis supports the lens barrel. The second optical axis is substantially parallel to the transverse direction of an object to be captured by the CCD unit when the bottom of the chassis is substantially parallel to the transverse direction of the object.
