    摘要： A display system includes an optical element through which light diverges and an imaging optical system configured to form an image by projecting diverging light diverging through the optical element. In the display system, the image formed by the imaging optical system is visually recognized by a viewer, and a condition in an equation tan 0≥(T×B)/(S×O) is satisfied, where θ denotes a divergence angle of the optical element, T denotes distance between the image forming optical system and the formed image, B denotes a range of an eye box that is an area through which the formed image can visually be recognized, S denotes distance between the formed image and a viewpoint of the viewer of the formed image, and O denotes distance between the optical element and the image forming optical system. In the above equation, each distance indicates length of an optical path that passes through a center of an image formed by the light when an object is observed from a reference eyepoint.

    摘要： A powder container includes a cylindrical container body to contain a powder, having an opening in one end thereof, to convey the powder contained in the container body to the opening with rotation of the container body, and having a container-body projection provided on an outer circumferential surface of the container body; and a cylindrical holder, into which the end of the container body having the opening is inserted, to hold the container body rotatably, having a powder outlet through which the powder is discharged from the holder and a holder projection provided on an inner circumferential surface thereof. The container-body projection repetitively contacts and separates from the holder projection with rotation of the container body to vibrate the container body and the holder.

    摘要： A projector includes an image forming unit configured to emit image light that forms an image and an imaging optical system configured to form an image by reflecting the image light. S magnification power at a point of the imaging optical system where the image light is incident and optical-path length between the image forming unit and the imaging optical system is short is made higher than a magnification power at a point of the imaging optical system where the image light is incident and the optical-path length between the image forming unit and the imaging optical system is long.
