Abstract: The invention provides a tablet input device with a switch in which no pressing force for operating a pushbutton switch is changed in accordance with a pressing position of an operating button. When an operating portion 61 of an operating button 6 stored to a tablet case 7 is shifted from its center and is pressed and operated, an upper sheet 51 and a lower sheet 52 of a tablet sheet 5 located below the operating button 6 come in contact with each other in a shifting position by a spherical crown-shaped portion 62 of the operating button 6 so that output data showing a shift operating amount from the contact position are outputted. When the operating portion 61 is shift-operated and pressed against elastic force of the elastic leg body 8, the tablet case 7 is horizontally pushed down and a bottom portion 71 of the tablet case 7 pushes down an actuator 32 of a pushbutton switch 31 so that the pushbutton switch 31 is operated.
