Operation device and x-ray imaging unit

The purpose of the present invention is to suppress power consumption by correcting a threshold value at a necessary timing. An operation device (200) is provided with: a contact determination unit (touch-sensitive sensor control unit (235)) that determines whether or not a touch-sensitive sensor is contacted on the basis of a touch-sensitive sensor output value from the touch-sensitive sensor and a threshold value; and a correction unit (232) that corrects the threshold value, and the correction unit (232) starts the execution of the correction after determining that the predetermined condition has been satisfied. 本发明通过在必要的时机执行阈值的校正来抑制耗电。操作装置(200)具有：接触判断部(触敏传感器控制部235)，其基于来自触敏传感器的触敏传感器输出值与阈值，来判断所述触敏传感器是否被接触；以及校正部(232)，其对所述阈值进行校正，校正部(232)在判断为满足了规定条件后，开始执行校正。
