Problems solved by technology

[0005] However, in the existing beam emitting device, since the beam is only scanned one-dimensionally in the main scanning direction, a driving mechanism to be driven in the sub-scanning direction must be additionally provided for forming a two-dimensional image using the emitted beam.
Therefore, the existing image imaging device has the following problems: complex structure, inability to achieve small size and light weight

Abstract

The invention discloses a light beam transmitting device and an image forming device which is simple in structure and capable of transmitting light beam to any direction of two-dimensional coordinates. A unit is arranged on the light beam transmitting device (1). A optical deflection mechanism (40) comprises a permeable optical deflection tray (30) in optical deflection area (32) capable of transmitting incidence beam to different direction of two-dimensional coordinates according to its incidence direction; and a driving mechanism for driving the permeable optical deflection tray (30) to rotatably switch incidence direction of a beam emerged from light supply apparatus (10) to incidence direction of the permeable optical deflection tray (30).

Description

Technical field [0001] The present invention relates to a light beam emitting device that emits a light beam emitted from a light source device in a predetermined direction, and an image imaging device that uses the light beam to form images. Background technique [0002] In the past, light beam emitting devices have been widely used in image imaging devices such as laser printers, digital copiers, and facsimile machines, barcode reading devices, and vehicle distance measuring devices. Here, as a beam emitting device used in an image imaging device, a polygon mirror periodically deflects the beam emitted from a laser light emitting element such as a laser diode to repeatedly scan it on a scanned surface such as a photoreceptor. On the contrary, in the measuring device, the light of the scanning beam emitted from the beam emitting device is detected by the light detector and reflected on the irradiated object, thereby detecting the information. At this time, the reflected light be...
