CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority to Japanese Patent Application No. 2019-075109 filed on Apr. 10, 2019. The entire contents of this application are hereby incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to an X-ray imaging apparatus.Description of the Background Art[0003]Conventionally, an X-ray fluoroscopic imaging apparatus including an operation panel is known. Such an X-ray fluoroscopic imaging apparatus is disclosed in Japanese Patent Laid-Open No. 2011-224120, for example.[0004]Japanese Patent Laid-Open No. 2011-224120 discloses an X-ray fluoroscopic imaging apparatus including an examination table including a top board on which a subject is placed, an X-ray tube that irradiates the subject placed on the top board with X-rays, and an X-ray detector that faces the X-ray tube with the subject interposed between the X-ray detector and the X-ray tube an...

AI Technical Summary

Benefits of technology

The patent describes a structure for an X-ray imaging apparatus that includes a sensor for detecting liquid ingress. The sensor includes two conductive patterns that are positioned along the outer edge of the substrate, which surrounds the circuits. This structure makes it easy to sense the entry of liquid before it reaches the circuits. The sensor includes a power supply, a resistor, and a sensing circuit, which are connected to the first conductive pattern. When the two conductive patterns are short-circuited, the sensor can detect the voltage difference and sense the short-circuit. This structure provides an effective and simple way to monitor liquid ingress and prevent damage to the device.

Problems solved by technology

In this case, liquid such as a drug and a specimen may spill on the examination table.

In addition, when the X-ray fluoroscopic imaging apparatus (X-ray imaging apparatus) is wiped and cleaned with a cloth or the like, liquid such as water contained in the cloth or the like may also spill on the examination table.
