A touch-operating input device comprising: an operation panel including a touch surface and a rear surface opposite to the touch surface; a plurality of translucent touch sensors disposed on the rear surface of the operation panel; a plurality of sub-light sources disposed in a position facing the operation panel wifh the plurality of translucent touch sensors interposed therebetween; a light-shielding panel disposed in a position opposite to the plurality of translucent touch sensors with respect to the plurality of sub-light sources; a plurality of main light sources disposed in a predetermined position facing the plurality of sub-light sources with the light-shielding panel interposed therebetween; and a control circuit configured to perform control of lighting and extinguishing the sub-light sources and the main light sources; wherein a plurality of translucent operation buttons individually corresponding to the plurality of translucent touch sensors and translucent outer portions formed individually in outer portions of the plurality of translucent operation buttons are formed on the rear surface of the operation panel by concealed printing such that the operation buttons and the translucent outer portions are illuminated and displayed only when the light sources are lit (7, 11); the light-shielding pane is provided with a plurality of non-light-shielding regions individually corresponding to the plurality of translucent touch sensors; light of each of the plurality of main light sources that are lit is configured to pass through the non-light-shielding region and the translucent touch sensor so that only the translucent operation button corresponding to each of the plurality of main light sources is illuminated and displayed, light of each of the plurality of sub-light sources that are lit is configured to pass through the translucent touch sensor so that only the translucent outer portion corresponding to each of the plurality of sub-light sources is illuminated and displayed, and when the control circuit turns on the main light source corresponding to each of the translucent operation buttons that can be operated, the control circuit on condition that the translucent operation button corresponding to the main light source that is turned on is operated, turns on the sub-light source corresponding to the translucent operation button that is operated. an operation panel including a touch surface and a rear surface opposite to the touch surface; a plurality of translucent touch sensors disposed on the rear surface of the operation panel; a plurality of sub-light sources disposed in a position facing the operation panel wifh the plurality of translucent touch sensors interposed therebetween; a light-shielding panel disposed in a position opposite to the plurality of translucent touch sensors with respect to the plurality of sub-light sources; a plurality of main light sources disposed in a predetermined position facing the plurality of sub-light sources with the light-shielding panel interposed therebetween; and a control circuit configured to perform control of lighting and extinguishing the sub-light sources and the main light sources; wherein a plurality of translucent operation buttons individually corresponding to the plurality of translucent touch sensors and translucent outer portions formed individually in outer portions of the plurality of translucent operation buttons are formed on the rear surface of the operation panel by concealed printing such that the operation buttons and the translucent outer portions are illuminated and displayed only when the light sources are lit (7, 11); the light-shielding pane is provided with a plurality of non-light-shielding regions individually corresponding to the plurality of translucent touch sensors; light of each of the plurality of main light sources that are lit is configured to pass through the non-light-shielding region and the translucent touch sensor so that only the translucent operation button corresponding to each of the plurality of main light sources is illuminated and displayed, light of each of the plurality of sub-light sources that are lit is configured to pass through the translucent touch sensor so that only the translucent outer portion corresponding to each of the plurality of sub-light sources is illuminated and displayed, and when the control circuit turns on the main light source corresponding to each of the translucent operation buttons that can be operated, the control circuit on condition that the translucent operation button corresponding to the main light source that is turned on is operated, turns on the sub-light source corresponding to the translucent operation button that is operated.
