<p>PURPOSE:To prevent damage, caused by destruction and mischief from the outside, by providing a contactless sensor, consisting of paired light emitting and receiving elements, approaching a window glass internal surface in an automobile and performing keyless entry by hand-passover action from the outside. CONSTITUTION:An electronic key device 14 is fixed to an internal surface of a side window 12 in a driver's seat side door 10 of an automobile, being provided with an unlocking motor 18 for pulling up a knob of a door lock to the upper. While the device 14 is provided with paired ID inputting elements 24-1-24-5 consisting of five sets of paired light emitting and receiving elements corresponding to an input numeral, paired resetting light emitting and receiving elements 30 and paired starting light emitting and receiving elements 32 or the like. The device 14 is energized by the paired elements 32, fetching a predetermined ID signal by the action of a hand passing over the paired elements 24 from the outside of the window glass 12, and the motor 18 is driven being based on the input signal. Accordingly, damage, caused by destruction and mischief, can be prevented.</p> |
