An image-based acceptance learning device () learns a result of determination as to whether a planar object () is acceptable or defective based on at least one of a three-dimensional shape or a color on a surface of the planar object (). The device () includes a surface image receiver () to receive an inputted two-dimensional data being image data of the surface of the planar object (), a determination information receiver () to receive an inputted determination information indicating the result of determination as to whether the planar object () corresponding to the two-dimensional data is acceptable or defective, and a learner () to learn, based on the two-dimensional data and the determination information, a relevant area (R) including the three-dimensional shape or the color on the surface in the two-dimensional data. The relevant area is a basis for the determination information.

Image-based acceptance learning device, image-based acceptance determination device, and image reading device

The present disclosure relates to an image reading device having a highly-accurate structure that enables an easy increase in depth of field, that is, improvement in the depth of the field, without need for a change in basic characteristics of lenses. An overlap preventer () disposed between a lens array () and a sensor element array () to prevent overlap of images formed by lenses () is included. A slit section () that is the overlap preventer () includes multiple slit plates () arranged in a main scanning direction and extending in a sub-scanning direction to partition off a space, and the slit plates () are fixed to fixing plates ().

An image sensor unit includes: a visible light cut filter that is arranged between a first light source and a first light guide and blocks light including visible light having wavelengths longer than those of ultraviolet light; a lens body that condenses light generated on a reading target by light radiated from the first light guide and light radiated from a second light guide; a line sensor that receives the light condensed by the lens body; and an ultraviolet light cut filter arranged between the lens body and the line sensor and blocks ultraviolet light.

Image sensor unit

A capacitance detection device includes a first electrode and a second electrode that at least partially face each other on opposite sides of a transfer path. An oscillator circuit forms an electric field between the first electrode and the second electrode. A detection circuit detects a change in capacitance between the first electrode and the second electrode. At least one of the oscillator circuit and the detection circuit is included in each of a first board and a second board. The first board is disposed such that a side surface of the first board faces the first electrode in an electric field direction, and the second board is disposed such that a side surface of the second board faces the second electrode in the electric field direction.

When a switch is set to off, and a switch is set to on, the voltage of a SigOut terminal is stabilized with a reference voltage, and a bias voltage is applied to a capacitor. Changing the switch from on to off, with the bias voltage retained in the capacitor, a detection signal which is input via a SigIn terminal is amplified with the reference voltage as a reference, and an amplified signal is output from the SigOut terminal.
