PROBLEM TO BE SOLVED: To furthermore relax waterproof properties required in an entire input device and to make the input device robust against prank.SOLUTION: An input device 1 for a password key for entering and leaving includes a ten-key sheet 2 mounted on an outdoor surface of a glass plate 4 of a door and a device body 3 attached to an indoor surface of the glass plate 4, and the device body 3 includes a plurality of excitation parts S1 to S# which always generate vibrations, vibration receiving parts R1 to R20 which receive vibrations generated by the excitation parts to detect vibration reception levels, and a control device 10. The control device 10 always puts the excitation parts S1 to S# and the vibration receiving parts R1 to R20 always in a vibrating state and includes an operated key specifying means which, when vibration reception levels of any one pair of vibration receiving parts are changed from previous vibration reception levels, specifies the execution of touch operation on a key part corresponding to the pair of vibration receiving parts. |
