Patent number: 11953672Abstract: An optical unit includes a first barrel, a second barrel, a third barrel, and a position detection unit. Eight magnets including first and second magnets are fixed to the first barrel. A first and second coils are fixed to the second barrel. The position detection unit includes a magnetic sensor configured to detect magnetic fields generated by the first and second magnets and to generate a detection signal having a corresponding relation with a position of the first barrel. The third barrel includes a position defining surface parallel to a moving direction of the first barrel. The position detection unit is fixed to the position defining surface.Type: GrantFiled: October 30, 2020Date of Patent: April 9, 2024Assignee: OLYMPUS CORPORATIONInventors: Jun Shinzato, Masaru Inamura, Takehiko Iguchi

Patent number: 9791659Abstract: The present invention provides an imaging module capable of performing positioning of an imaging element unit, and a lens unit at a low cost and with high precision and an electronic device including the imaging module. An imaging module 100 includes a lens unit 10 including VCMs 16A, 16C, and 16E which move a lens group 12 in an x direction, a y direction, and a z direction, respectively, terminals 14A and 14B which are connected to the VCM 16A, terminals 14C and 14D which are connected to the VCM 16C, and terminals 14E and 14F which are connected to the VCM 16E, and an imaging element unit 20 including terminals 24A to 24F which are connected to the terminals 14A to 14F. Exposed areas of the terminals 14A and 14B are larger than exposed areas of the terminals 14C to 14F.Type: GrantFiled: January 27, 2016Date of Patent: October 17, 2017Assignee: FUJIFILM CorporationInventors: Kenji Yamakawa, Yoshiyuki Takase, Masaru Inamura, Tatsuya Fujinami, Manabu Tobise

Patent number: 9565347Abstract: The invention provides an imaging module having second connecting portions capable of reliably performing probing and can maintain a small installation space, and an electronic apparatus including the imaging module. A lens unit includes at least one drive unit, a housing, a first connecting portion that is electrically connected to an imaging element unit, a first wiring portion that electrically connects the drive unit to the first connecting portion, a plurality of second connecting portions that are disposed outside the housing, and a second wiring portion that electrically connects the second connecting portions to the drive unit. The second wiring portion includes wires that are electrically connected to the drive unit to which the first wiring portion is connected, and at least a part of the second wiring portion extends to the outside of the housing in a direction in which an element wiring portion extends from the support portion.Type: GrantFiled: January 21, 2016Date of Patent: February 7, 2017Assignee: FUJIFILM CorporationInventors: Motokazu Shimizu, Yoshiyuki Takase, Tatsuya Fujinami, Manabu Tobise, Masaru Inamura
