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

Provided are an image-reading device and an inkjet recording device with which it is possible to read an image more accurately. An image-reading device, in which a recording medium in which an image is recorded and a reading range in which a part of the image is read are moved relative to each other to read the image, is provided with: a light source; a light-blocking part for blocking light emitted from the light source toward the recording medium; and a reading means for detecting light that has passed through a slit provided in the light-blocking part from among reflected light emitted fromthe light source that has passed through the slit and is incident on the reading range of the recording medium, 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...
