Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a schematic structural diagram of the image forming apparatus 100 including the image reading unit 6 using the reading module (read device) 50 of the present invention. exist figure 1 In the middle, the image forming apparatus 100 (as an example, a digital multi-composite machine) performs a copying operation, and the image data of the original is converted to a read image signal in the image reading unit 6 to be described later. On the other hand, in the image forming portion 3 in the digital composite machine main body 2, figure 1 The photosensitive drum 5 rotating in the middle clockwise direction is uniformly charged with the charged unit 4. Then, the electrostatic drum 5 is formed on the image reading unit 6, the electrostatic latent image read, the image reading unit 6 is formed on the photosensitive drum 5 is formed by the laser beam from the exposure un...

Abstract

The present invention provides a reading module, an image reading apparatus and an image forming apparatus including the reading module. The reading module includes a light source, an optical system and a sensor. The optical system images the reflected light of the light irradiated to the original from the light source as image light. The sensor converts the imaged light into electrical signals. The optical system includes a mirror array in which a plurality of mirrors are connected, and a plurality of aperture units. Viewed from the main scanning direction, each mirror and adjacent mirrors reflect light at different angles.

Description

Technical field [0001] The present invention relates to a reading module, an image reading apparatus, such as an image light, such as a digital copy, an image scanner, or the like, and a read module, and an image reading apparatus including a reading module. Background technique [0002] Conventionally, as a digital multi-color composite machine such as an electrophotographic method, the reading method of the image reading apparatus has a CCD method using a charge coupling device called a CCD (Charge Coupled Devices) sensor, and is called CMOS. (Complementary MOS complementary metal oxide semiconductor) The optical conversion element of the sensor. [0003] The CCD mode is an image sensor for the original size of 1 / 5 to 1 / 9 size, and a plurality of planar mirrors and optical lenses form a narrowing image and read an image. As the advantage of the CCD mode, you can enumerate the depth of view. Here, the depth of field refers to the position of the optical axis even from the positi...
