ABSTRACT:
In a display device for a recording device, when the power supply of the recording device is switched on, a display lamp is lighted to display that power-on. When the recording device is operated, and recording information is input, a misoperation detection circuit detects misoperation. When a misoperation is detected, a controller controls the display lamp to indicate the misoperation. When a device-trouble is detected, such as lowering of voltage in the recording device, the controller controls the display lamp to indicate the misoperation. The display lamp displays for indicating device-trouble differs from both the display at power-on and the display indicating a misoperation.
