摘要： An optical unit with shake-correction function is provided and includes: a movable body, a rotational support structure, a gimbal mechanism, and a fixed body. The rotational support structure rotatably supports the movable body having a camera module around an optical axis. The rotational support structure is rotatably supported by the gimbal mechanism around a first axis and a second axis. The rotational support structure includes a first annular groove in the movable body, a plate roller having a second annular groove, multiple spherical objects to roll between the first annular groove and the second annular groove, and a pressurization structure configured to apply a force for bringing the first annular groove and the second annular groove close to each other in the direction of the optical axis.

摘要： A card reader may be structured to perform at least one of reading of magnetic data recorded in a card and writing of magnetic data to the card. The card reader may include a metal detection sensor structured to detect a foreign matter including metal, a judgment part configured to compare an output of the metal detection sensor with a predetermined threshold value to determine whether abnormality has occurred or not, and an abnormality determination part configured to obtain a difference between a reference value and an output of the metal detection sensor in a case that the judgment part determines that the abnormality has occurred to determine as the foreign matter in a state that the difference is within a stable determination width.

摘要： An optical unit with shake-correction function is provided. A movable body is supported by a fixed body via a gimbal mechanism. The fixed body includes a case surrounding the movable body. The gimbal mechanism includes a gimbal frame having a second axis-side extension part protruding in a direction of a second axis and a second connecting mechanism connecting the second axis-side extension part and the case. The second axis-side extension part includes a first portion extending in a direction of Z-axis, a bent portion bending from an end of the first portion, and a second portion extending from the bent portion in a −Z direction. The second connecting mechanism connects the second portion and the case, and the fixed body includes an object-side end plate portion facing the bent portion from the direction of the Z axis on an outer side of the first portion in a radial direction.

摘要： The present invention provides a wide-angle lens capable of obtaining a suitable negative power even when a thickness of a first lens is increased in order to increase strength against impact. The wide-angle lens 100 has a front group 110, an aperture 80, and a rear group 120. Assuming that a central thickness in an optical axis direction of a first lens 10 is T1 (mm) and a focal length of the entire lens system is f0 (mm), the following conditional expression: 1.500≤T1/f0≤2.000 Conditional expression (1) is satisfied. Therefore, it is possible to suppress the first lens 10 from being damaged by impact. In addition, it is possible to prevent the first lens 10 from becoming too thick to obtain suitable negative power.

摘要： A manufacturing method of a plastic lens formed by using a metal mold having a fixed mold and a movable mold. The plastic lens comprises a flange part surrounding a lens face, and an image side face of the flange part comprises a black coating part and an outer peripheral part. The manufacturing method may include a molding process in which the plastic lens is molded by using the fixed mold for molding an object side lens face and the movable mold for molding an image side lens face and the flange part, a mold opening process in which the metal mold is opened by moving the movable mold, and a pushing-out process in which the outer peripheral part is pushed out by an ejector pin disposed in the movable mold when the mold opening process is performed or, after the mold opening process has been performed.

摘要： An optical unit with a shake correction function rotates a movable body around X, Y, and Z axes to perform a shake correction. The optical unit with a shake correction function includes a flexible printed board pulled out from the movable body in a +X direction and a board support part to support the flexible printed board at a position away from the movable body in an X-axis direction. The flexible printed board includes a first extending part pulled out from the movable body in the +X direction along an XY plane, a meandering part extending in a Y-axis direction while meandering in the X-axis direction after being curved in a Z-axis direction from an end of the first extending part in the Y-axis direction, and a second extending part extending in the +X direction along the XY plane in the +X direction of the meandering part.
