Image reading apparatus and image forming device

Abstract

The invention provides an image reading apparatus and an image forming device; the image reading apparatus includes a reader, a conveying path, a conveyer, a conveyer driving unit, a conveyer housing,a lighting unit, a cooler, and a frame. The reader reads an image on a sheet at a predetermined reading position. The conveying path guides the sheet having the image to the reading position and guides the sheet read by the reader in an ejecting direction. The conveyer conveys the sheet along the conveying path. The conveyer driving unit drives the conveyer. The conveyer housing supports the conveying path, the conveyer, and the conveyer driving unit. The lighting unit is fixed to an interior of the reader and illuminates the sheet conveyed by the conveyer to the reading position. The coolercools the lighting unit. The frame separately fixes the reader and the conveyer housing. In addition, the cooler is fixed to the conveyer housing.

Description

technical field [0001] The present invention relates to an image reading device and an image forming device including the image reading device. Background technique [0002] Conventionally, an electrophotographic image forming apparatus forms a reference image for image quality adjustment on paper, changes image forming conditions, etc., based on a read value obtained by reading the reference image by a reading unit, and adjusts the image quality so that the image quality becomes better. constant. [0003] An image sensor (CCD), an illumination unit (LED) for irradiating paper, and an optical system (mirror, lens, etc.) for forming an image of light irradiated on paper from the illumination unit on the image sensor are provided in the reading unit. [0004] When the vibration is transmitted to the image sensor and mirror of the reading unit, the read image fluctuates or the reading position changes, so there is a problem that the image formed on the paper cannot be read acc...

Problems solved by technology

[0012] However, in the configuration in which the cooling fan is fixed to the housing of the reading unit, the vibration of the fan is transmitted to the inside of the reading unit.

[0013] In addition, a structure in which a cooling fan is fixed to the frame of the reading unit via a vibration-proof member is considered, but there is a problem that the number of parts increases and the cost increases.

[0014] In addition, a structure in which components constituting the reading unit, such as mirrors and CCDs, are fixed via a vibration-proof member is also conceivable, but the number of components increases and the cost increases, and it is difficult to ensure the positional accuracy of mirrors, CCDs, etc.
