Abstract: A recording medium transport device includes a first rotating member, a second rotating member, a first shaft, a second shaft, a contact member, a pressure member, and a transmission part. The second rotating member is configured to form, together with the first rotating member, a nip, and nips a recording medium in the nip so as to transport the recording medium. The contact member is spaced from the first rotating member and brought into contact with the recording medium. The contact member is movable about an axis of the first shaft in an arc-shaped path. The pressure member is movable about an axis of the second shaft in an arc-shaped path and presses the second rotating member toward the first rotating member. The transmission part is brought into contact with the pressure member so as to transmit a movement of the pressure member to the contact member.

Abstract: A fixing device includes a light source that emits laser light; a condensing member including a lens having a first surface from which the laser light enters and a second surface from which the laser light emerges, the lens condensing the laser light that has entered from the first surface and emitting the laser light from the second surface; and a roller provided in contact with the condensing member and that transports a recording medium advanced into a position between the roller and the condensing member. A portion of the second surface is made of a material that blocks the laser light. In a section perpendicular to an axis of rotation of the roller, a plane of contact between the roller and the condensing member includes at least a part of the portion made of the material that blocks the laser light.

Abstract: A fixing device includes a light source that radiates a laser beam, a converging member that converges the laser beam, and a roller that is positioned so as to be in contact with the converging member and that transports a recording medium, which enters between the roller and the converging member. The converging member includes a lens that converges the laser beam, which is incident on a first surface of the lens, and emits the laser beam from a second surface of the lens and a holding member made of a material that does not transmit the laser beam, the holding member holding the lens. In the cross-sectional view perpendicular to a rotation axis of the roller, a contact surface in which the roller and the converging member are in contact with each other includes at least a portion of a surface of the holding member and the second surface.

Abstract: An engine starting/stopping switch device is provided that includes a switch unit that switches over switching modes in response to linear movement of a movable member, a push button that is linked to the movable member so as to drive the movable member in response to a pushing operation, and a coil antenna that outputs transponder drive radio waves for generating an electromotive force in a transponder built into a portable device, wherein the coil antenna (15) is disposed coaxially with the push button (14) so that at least part of the coil antenna (15) is inserted into the interior of the push button (14). This enables the operability of a push button to be improved and enables the size in the radial direction of the push button to be reduced.
