Abstract: A battery storage structure for a waterproof electric instrument comprises battery holders on whose both ends are arranged a pair of electrodes which come in contact with electrode sections of cylindrical batteries; a box-shaped case for a waterproof electric instrument which houses the battery holders; a battery loading orifice to load the cylindrical batteries from outside of the case to the battery holders; a loading orifice closing lid operable to open and close the battery loading orifice; and a water-tight seal to hermetically close the loading orifice closing lid against the battery loading orifice, wherein the loading orifice closing lid and the battery loading orifice have a screw section, both screw sections being able to screw together, and wherein the loading orifice closing lid screws into the battery loading orifice, thereby hermetically closing the battery loading orifice.

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.
