Embodiment Construction

[0021] From the description of this specification and the drawings, at least the following matters are clarified.

[0022] A color measuring device for measuring the color of a printed pattern printed on a medium is specified, the color measuring device is characterized in that it includes: a pressing member for pressing the medium; a color measuring unit for measuring the color of the printed pattern. pattern for color measurement; a power source that outputs power for pressing the pressing member against the medium; a detection unit that detects displacement of an output unit of the power source; and a controller that makes the color measurement unit Colorimetrically measuring the print pattern printed on the medium pressed by the pressing member, and the controller decreases the power output from the power source from the state in which the medium is pressed by the pressing member, and based on The abnormality of the power source is detected by the detection result of the d...

Abstract

The present invention is a color measurement device for color measurement of a printed pattern printed onto a medium, the color measurement device characterized by comprising a pressing member for pressing the medium; a color measurement section for performing color measurement of the printed pattern; a power supply for outputting power for the pressing member to press the medium; a detection section for detecting displacement of an output section of the power supply; and a controller for causing the color measurement section to perform color measurement of the printed pattern which was printed onto the medium pressed by the pressing member, the controller being adapted to reduce the power output by the power supply from a state in which the pressing member was pressed against the medium, and to detect a malfunction of the power supply on the basis of the detection result obtained from the detection section.

Description

technical field [0001] The invention relates to a color measuring device and an abnormal detection method of the color measuring device. Background technique [0002] When measuring the color of a printed pattern with an optical sensor or the like, accurate color measurement cannot be performed if the distance between the sensor and the printed pattern is not appropriate. In particular, the distance between the sensor and the printed pattern may not be stable due to wrinkling or curling of the surface of the printed pattern printed on the medium due to drying of ink or heating during fixing. Therefore, a method of performing color measurement while pressing a medium on which a print pattern is printed is conceivable. [0003] As a method of pressing the medium, for example, a mechanism is known in which a plate-shaped bottom plate on which paper as a medium is placed is brought into pressure contact with a roller disposed opposite to the bottom plate by operating a pressing...
