摘要:
Semiconductor surface emitting elements having a plurality of wavelengths being manufactured on a signal substrate through MOVPE selective growth. More specifically, provided is a semiconductor light emitting element array which comprises; a semiconductor crystal substrate; an insulating film disposed on a surface of the substrate, the insulating film being divided into two or more regions, each of which having two or more openings exposing the surface of the substrate; semiconductor rods extending from the surface of the substrate upward through the openings, the semiconductor rods each having an n-type semiconductor layer and a p-type semiconductor layer being laminated in its extending direction, thereby providing a p-n junction; a first electrode connected to the semiconductor crystal substrate; and a second electrode connected to upper portions of the semiconductor rods; wherein the heights of the semiconductor rods as measured from the substrate surface vary by each of the two or more regions.

An aspect is a medium detection device to detect a slack of a medium to be introduced into a fixation device in an image formation apparatus. The fixation device is detachable from a part of the image formation apparatus other than the fixation device. The medium detection device includes a lever support provided at the fixation device, a lever supported by the lever support such that the lever moves or displaces when the lever comes in contact with slack medium, a sensor support provided at the part of the image formation apparatus other than the fixation device, and a sensor supported by the sensor support and configured to detect the movement or the displacement of the lever.

A medium tray (101) comprises a medium support (1) connected to a medium feeding section (100) of an image recording apparatus (200) and receiving record medium (P), and a medium guide (5) extending from the medium support (1) and supporting the record medium (P) such that an angle of a rear portion of the record medium (P) is changed. A lengthy record medium (P) having a length greater than the medium support (1) is supported by the medium guide (5) with the rear portion thereof directed at a different angle so that the length record medium (P) is loaded in the medium tray (101) without enlarging an area projecting from the image recording apparatus (200).
