Abstract: To provide a mutual authentication system which is not required to erase master key when a slave device is replaced. The storage part stores a temporary key which is key data used temporarily and a master key which is key data used for authentication. The storage part stores the temporary key. The key confirmation unit inquires whether the slave device stores the master key. The key confirmation response unit confirms whether the master key has already been stored in the storage part for an inquiry from the master device and responds. The key introduction unit encrypts the master key by using the temporary key and transmits to the slave device. The key storage unit decrypts the encrypted master key by using the temporary key and stores in the storage part. The main authentication unit and the sub-authentication unit authenticate with each other by using the master key.

Abstract: A drive device is provided and includes: a movable body including an attachment part, to which an optical module is attached; a fixed body; and a support part rotatably supporting the movable body about an optical axis of the optical module attached to the attachment part with respect to the fixed body. The movable body includes a movable body-side fixing part, to which a flexible printed circuit pulled out of the optical module is fixed. The fixed body includes a fixed body-side fixing part, to which the flexible printed circuit is fixed. And, a portion between the movable body-side fixing part and the fixed body-side fixing part in a region along an outer periphery of the fixed body is set as a region drawn around in an attitude causing a thickness direction of the flexible printed circuit to be directions both orthogonal to a direction of the optical axis.

Abstract: An optical unit with a shake correction function includes a gimbal mechanism swingably supporting a movable body and including a connection mechanism including a spherical body and a support part contacted with the spherical body. The movable body includes a holding part holding a gimbal frame receiving member including a plate part fixed with the spherical body and a pair of protruded parts protruded to the support part side. The holding part is formed in a cut-out recessed part including a rear wall face, a pair of side wall faces, and a bottom wall face. When viewed in the optical axis direction, a pair of the protruded parts overlaps the support part. The movable body includes a facing wall part facing a pair of the protruded parts, and a separated distance between the facing wall part and the protruded parts is narrower than a thickness of the support part.
