PURPOSE:To automate a check process by setting a white balance measuring condition automatically after stopping the movement of a receiver in interlocking with a conveyor so as to measure the white balance. CONSTITUTION:When a color receiver placed on a pallet on a conveyor stops at a measuring station and a measurement start signal is outputted from the conveyor, a system controller receives the signal and outputs a channel changeover signal to the color receiver automatically to switch the designated channel and to receive a white balance measurement signal. Simultaneously, magnetic erasing action is applied by a magnetic erasing coil. Then a sensor mechanism section is adhered closely on the screen of the picture tube and a high sensor and a low sensor output is sent to a main controller via a measuring controller and each color luminance quantity is displayed on the display CRT by a graphic bar.
