This appearance inspection device receives image data representing an image of an inspection object photographed by a camera, and performs appearance inspection of the inspection object on the basis of the image data. In the appearance inspection, a first image that is an image represented by image data or a second image that is an image after image processing of the first image is an image affected by one or more parameters affecting the image of the inspection object, the parameters being a parameter group determined before the appearance inspection. In the first image or the second image, the color change amount in an edge range is smaller than a reference change amount. The edge range is a range having an edge vicinity including an edge of the inspection object, and is a range that is bounded by the edge of the inspection object and composed of a portion of the inspection object and a portion of the background of the inspection object. The color change amount in the edge range is the difference between the background color in the edge range and the color of a portion of the inspection object that is in the edge range.

The present invention enables high-speed printing in an inkjet recording device without causing deviation of the charged ink droplet landing position in any longitudinal dot array pattern. When multi-stage printing of dots in a column is performed one by one from each stage in an alternating manner, charged ink droplets among columns of ink droplets for use in printing in each stage are placed as close as possible to the front. When printing n print dots in the upper stage and m print dots in the lower stage, where n < m, ink droplets 211, 311, 212, and 312 from I_1 to I_2n are assigned as charged ink. At and after I_2n+1, a charged ink droplet 213 is placed first, and uncharged ink droplets are placed in order at the remaining positions. When doing so, counting from I_1, the odd-numbered positions are made to correspond with the lower stage, and the even-numbered positions are made to correspond with the upper stage.

Provided is an inkjet recording device capable of automatically setting an optimal excitation voltage for a piezoelectric element so that ink droplets are formed in a wide range of usage environment temperatures.　This inkjet recording device comprises: an excitation voltage circuit that applies an excitation voltage to a piezoelectric element provided to an ink nozzle; and a controller that performs setting of the excitation voltage. A liquid level sensor made of a rod-shaped conductive material and a GND terminal made of a rod-shaped conductive material are arranged inside a main ink container. A liquid level height of ink in the main ink container 10 is detected by measuring a terminal voltage between the liquid level sensor and GND. Ink viscosity is controlled by fine-tuning the liquid level height according to an ambient temperature. In a case where the ambient temperature is no more than 30℃, the inkjet recording device sets the excitation voltage so that printing is performed using an excitation voltage with which the ink column is shortest, and in a case where the ambient temperature is 30℃ or more, the device sets an excitation voltage so that, after raising the ink viscosity to a higher viscosity, printing is performed in a range of ±30% of the excitation voltage with which the ink column is shortest. Due to this configuration, the device is capable of automatically setting the excitation voltage within a wide temperature range.
