Title: IMAGE READING DEVICE, IMAGE RECORDING DEVICE, AND METHOD FOR CONTROLLING IMAGE READING DEVICE
Abstract:
Provided are: an image reading device which is capable of generating more appropriate imaging data of a reference member; an image recording device; and a method for controlling the image reading device. The image reading device is provided with: a reading means which reads the surface of an object to be read, by using imaging elements to detect reflected light from the surface of the object to be read; a reading control means which causes a recording medium reading operation and a reference member reading operation to be performed by the reading means; an imaging data generation means which generates reference member imaging data used to calibrate the reading means; and a moving means which performs a movement operation in which the reading means and/or the reference member are/is moved in the direction of the axis of incidence of the light on the imaging elements. In the reference member reading operation, the reading control means causes the movement operation to be performed such that the distance between the surface of the reference member and the light incidence surface of the reading means in the direction of the axis of incidence becomes a standard distance preset as the distance for when the recording medium reading operation is performed, and causes the reference member in a position in which the distance from the light incidence surface is the standard distance to be read by the reading means.
