Problems solved by technology

[0005] However, in the conventional image reading device, since the diffusely reflected light is also incident on the reading unit due to irradiation outside the reading range of the recording medium, the density of the image recorded on the outside of the reading range affects the reading. The reading result of the unit to the reading range, and the problem that the image cannot be read properly

Embodiment Construction

[0057] Embodiments of the image reading device and the inkjet recording device according to the present invention will be described below with reference to the drawings.

[0058] figure 1 It is a figure showing the schematic structure of the inkjet recording apparatus 1 which is embodiment of this invention.

[0059] The inkjet recording apparatus 1 includes a paper feed unit 10, an image recording unit 20, a paper discharge unit 30, and a control unit 40 ( figure 2 ). The inkjet recording apparatus 1 conveys the recording medium M stored in the paper feeding unit 10 to the image recording unit 20 under the control of the control unit 40, and the image recording unit 20 records an image on the recording medium M, and the recorded image is recorded. The medium M is transported to the paper discharge unit 30 . In the present embodiment, as the recording medium M, a medium having irregularities on the surface such as cloth or embossed paper is preferably used.

Abstract

The present invention provides an image reading device and an inkjet recording device capable of reading images more appropriately. An image reading device for reading an image by relatively moving a recording medium on which an image is recorded and a reading range for reading a part of the image includes: a light source; a light shielding unit that blocks light emitted from the light source toward the recording medium; and a reading unit , detecting the light passing through the slit among the reflected light of the light emitted from the light source and entering the reading range of the recording medium through the slit provided in the light shielding portion, and reading the image recorded on the recording medium.

Description

technical field [0001] The present invention relates to an image reading device and an inkjet recording device. Background technique [0002] Conventionally, there is an inkjet recording apparatus that records an image on a recording medium by ejecting ink from a plurality of nozzles of the recording head while moving a recording head provided with a plurality of nozzles that eject ink relative to the recording medium. In such an inkjet recording device, by reading a predetermined inspection image recorded on a recording medium by an image reading device that moves relative to the recording medium, it can be judged whether or not the recording medium is properly ejected from the recording head. ink. [0003] As such an image reading device, there is known an image reading device including a reading device having a linear sensor extending in a width direction intersecting with a direction of relative movement of the image reading device and a recording medium. unit, and a l...
