PURPOSE:To unnecessitate wiring works and make this touch switch applicable in a broad installation site, by providing a luminous source emitting light at the door knob by turning on a switching means, a light-receiving means, and also an output means transmitting a door-opening signal on receipt of light at the transom of automatic door. CONSTITUTION:When one touches a knob 1, the microswitch 14 is put on and the luminosity drive 15 transmits amplified luminosity drive signals to a luminous object 17. The luminous object 17 emits light. Next, when the light-receiver 33 of a detector 2 detects light 3 from the knob 1 through a lens 32, the output circuit transmits door-opening signals to a driving unit M and the driving unit M drives the door D in the opening direction, basing on the door-opening signal. Both detector 2 and driving unit M are installed inside the transom part B. In this way, wiring works become unnecessary and the installation work can be facilitated and further, it can remove effects like radio wave noises or the like in the nearby place of installation site. |
