Optical scanning device, image forming apparatus including optical scanning device, and position adjustment method of synchronization detection sensor mounted in optical scanning device |
摘要 |
An optical scanning device includes a light source that emits light, a deflector that deflects and scans the light emitted from the light source in a main scanning direction, a housing, a synchronization detection sensor, and a sensor board. The synchronization detection sensor is mounted in the housing, detects scanning light from the deflector, and outputs a write timing reference signal of image data. The sensor board is mounted with the synchronization detection sensor. The aforementioned sensor board is formed with a light transmitting hole for allowing a part of the scanning light to pass therethrough when an incident position of the scanning light for a light receiving surface coincides with a center position of the aforementioned light receiving surface in a sub-scanning direction on an extension line of a center line of the light receiving surface of the aforementioned synchronization detection sensor in the sub-scanning direction. |

1. An optical scanning device comprising:
a light source that emits light; a deflector that deflects the light emitted from the light source and allows the deflected light to be scanned in a main scanning direction; a housing that accommodates the deflector; a synchronization detection sensor mounted in the housing, detecting scanning light from the deflector, and outputting a write timing reference signal of image data; and a sensor board mounted with the synchronization detection sensor, wherein the sensor board is formed with a light transmitting hole for allowing a part of the scanning light to pass therethrough when an incident position of the scanning light for a light receiving surface coincides with a center position of the light receiving surface in a sub-scanning direction on an extension line of a center line of the light receiving surface of the synchronization detection sensor in the sub-scanning direction. |
