Abstract: An embroidery frame includes a base frame including a magnetic body, and a presser member configured to press a sewing object toward the base frame. The presser member includes a main body portion and a lever. The main body portion includes an opposing surface facing the base frame and a magnet. The lever includes a support portion, a point of application portion, and an operation portion. The support portion is rotatably supported on the main body portion to rotate around a rotational center. The point of application portion is provided on one end side of the lever with respect to the rotational center. The point of application portion is pivotable from a stand-by position to an application position in accordance with the operation portion being operated to the first side in a state where the presser member is disposed on the base frame.

Abstract: An embroidery frame includes a base frame, an opposing frame disposed in a first direction with respect to the base frame, a mounting portion, and a support member. The support member includes a support portion, a first section, a second section, and a third section. The first section includes a first inclined section extending, with respect to the opening, to the first direction and the second direction, and is coupled to the base frame or the mounting portion at a position further in the second direction than the support portion. The second section includes a second inclined section extending, with respect to the support portion, to the first direction and the second direction, and is coupled to the support portion. The third section couples the first section and the second section at a position further in the first direction than the support portion.

Abstract: An optical scanning device includes a deflector for deflecting a light beam to optically scan a scanned region on a scanned surface in a main scanning direction, and an imaging optical system for guiding the light beam deflected by the deflector, to the scanned surface. The imaging optical system includes an imaging optical element in which, in the main scanning direction, a distance to an optical axis from one effective end portion through which a light beam that enters one end portion of the scanned region passes is longer than a distance to the optical axis from another effective end portion through which a light beam that enters another end portion of the scanned region passes. In the imaging optical element, a thickness in an optical axis direction of the one effective end portion is thinner than a thickness in the optical axis direction of the other effective end portion.
