  • Publication number: 20240319477
    Abstract: A lens barrel includes first and second holding members configured to hold first and second lens units movable in an optical axis direction, a transmission member configured to move the second holding member in the optical axis direction, a driving unit configured to move the transmission member in the optical axis direction, a processor configured to control the driving unit, and a first output unit configured to output information about a position of the first holding member. Moving ranges of the first and second lens units overlap each other in the optical axis direction by a predetermined amount. The second holding member includes a biasing member. The lens barrel has a first state for restricting driving of the driving unit, and a second state for permitting driving of the driving unit. The processor determines whether the lens barrel is in the first or second state, using an output result from the first output unit.

  • Patent number: 11966189
    Abstract: A gear includes a gear body to be attached to a distal end of a driving shaft in an axial direction of the driving shaft and including teeth each extending obliquely with respect to the axial direction, and a stopping portion included in the gear body and configured in such a manner as to allow the driving shaft to which the gear body is attached to move in a circumferential direction. When the driving shaft moves in the circumferential direction, the stopping portion is enabled to stop the gear body from moving in the axial direction, the stopping portion stopping the gear body by coming into contact with a portion of the driving shaft.

  • Patent number: 11445786
    Abstract: A fastening tape having flexibility in a longitudinal direction of the fastening tape. The fastening tape includes a plurality of fasteners, a support, and magnetic material positioned on the support. The support defines a plurality of plateaus and a plurality of valleys. The magnetic material is positioned on at least a portion of one of the plurality of plateaus or the plurality of valleys of the support such that a height of the magnetic material varies in the longitudinal direction. Because the height of the magnetic material varies, the fastening tape is more flexible in the longitudinal direction. In some cases, the fastening tape is also flexible in the lateral direction.

  • Patent number: 11051590
    Abstract: The molded surface fastener has a base portion, right and left resin-intrusion-preventing wall portions standing on the base portion, and a plurality of engaging elements disposed between the right and left resin-intrusion-preventing wall portions. The resin-intrusion-preventing wall portions contain magnetic particles, and at least a part of a region formed of the resin-intrusion-preventing wall portions and the base portion has a concentration gradient portion in which a concentration of the contained magnetic particles is decreased toward at least one direction. This makes it possible to enhance the adhesion property between the part containing the magnetic particles and the part substantially containing no magnetic particles, and to suppress occurrence of cracks or the like between the containing part and the non-containing part of the magnetic particles at the time of manufacturing the molded surface fastener and at other times.
