Abstract: A stator unit included in a motor includes a base member, an armature, a circuit board, and a mold resin portion. The base member extends substantially perpendicularly to a vertically extending center axis. The armature and the circuit board are positioned above the base member. The circuit board is electrically connected to the armature. The mold resin portion covers the armature and the circuit board. In a process of forming the mold resin portion, the base member is supported by a first mold. Then, the first mold is joined to a second mold such that a cavity is provided therebetween. In this step, the second mold is pressed against a projection provided on an upper surface of the base member and on a radially outer side with respect to the circuit board in plan view. The projection thus pressed is squashed. Subsequently, molten resin is injected into the cavity.

Abstract: An image pickup apparatus includes an image pickup unit that picks up an object to generate moving image data. A detection unit detects one of a shooting direction of the image pickup unit and an attitude of the image pickup apparatus. A storage unit temporarily stores moving image data generated by the image pickup unit. An instruction unit instructs operation to photograph a still image. A recording unit reads out the moving image data traced back by a predetermined time period from a time point when still image photographing is instructed by the instruction unit, from the storage unit, and records the read-out moving image data in a recording medium. The recording unit records, relatedly with the moving image data, information concerning the detected one of the shooting direction and the attitude of the image pickup apparatus.

Abstract: An image pickup apparatus includes an image pickup unit that generates moving object image data. A detection unit detects a shooting direction of the image pickup and/or an attitude of the image pickup apparatus. A storage unit temporarily stores moving image data generated by the image pickup. An instruction unit instructs operation to photograph a still image. A recording unit reads out the moving image data traced back by a predetermined time period from a timing when still image photographing is instructed by the instruction unit, from the storage unit, and records the read-out moving image data in a recording medium. In the moving image data, traced back by the predetermined time period, the recording unit does not record, in the recording medium, at least a portion of the moving image data in the predetermined time period, based on the detected shooting direction and/or attitude of the image pickup apparatus.
