Claims

[Scope of utility model registration request]

A test signal generator that outputs a test signal for driving the needle to the meter, a television camera that photographs the display section of the meter, an XY movement mechanism in which one of the television camera and the meter is installed, and a rotating section for adjusting the meter indication. A rotating mechanism to which is coupled, an image processing means that image-processes the output signal of the television camera and detects the meter needle and scale, and movement commands and test signals for the XY movement mechanism necessary for the image processing means to detect the scale. Commanding the output signal value to the generator, calculating the indication error between the meter scale and needle, comparing the indication error with the specified range, giving rotation commands to the rotation mechanism to bring the indication error within the specified range, and moving the meter needle. An adjustment/inspection device for a pointer-type meter, comprising arithmetic control means for measuring time and comparing operating time and a specified value.
