Regardless of the height of the location of the movement, as long as it is in the detection area, the switch detects the movement of different height location in the detection area. Therefore, regardless of the difference of regulation between each states, it can be operated at any height of the movement. ## Claims ### Claim 1 A wireless non-contact switch for automatic doors comprising a non-contact sensor which can be installed on a wall surface with a beam-shaped detection area from upper area on the wall surface toward a floor surface, and detects moving body at different heights, a transmission side control circuit which generates a detection signal corresponding to predetermined operations based on detecting result from the non-contact sensor, a plurality of pseudo-touch area signs which show signs for pseudo-touching area on the wall surface at a plurality of desired heights, a wireless transmitter which transmits transmission signal wirelessly based on the detection signal from the transmission side control circuit, a wireless receiver which receive the transmission signal transmitted by the wireless transmitter and outputs receiving signal, a switch which controls opening and closing operations of the automatic door, and a receiving side control circuit which controls the opening and closing operation of the switch based on the receiving signal from the wireless receiver. ### Claim 2 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the non-contact sensor comprises one of a passive infrared sensor, an active infrared sensor and a micro-wave sensor. ### Claim 3 (depends on 2) A wireless non-contact switch for automatic doors of claim 2, wherein the wireless transmitter comprises a radio transmitter, and the wireless receiver comprises a radio receiver. ### Claim 4 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the wireless transmitter and the wireless receiver communicates by a light signal communication. ### Claim 5 (depends on 2) A wireless non-contact switch for automatic doors of claim 2, wherein the non-contact sensor is capable of being adjusted to move the beam-shaped detection area. ### Claim 6 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the non-contact sensor, the transmission side control circuit and the wireless transmitter are battery driven. ### Claim 7 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the non-contact sensor is capable of detecting direction of the operation which passes through the detection area, and the transmission side control circuit generates different detection signals according to the detected direction. ### Claim 8 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the transmission side control circuit generates the detection signals corresponding to attitudes of the operation which passes through the detection area, and the receiving side control circuit controls opening and closing of the switch according to the attitudes of the operation. ### Claim 9 (depends on 8) A wireless non-contact switch for automatic doors of claim 8, wherein the transmission side control circuit generates the detection signals corresponding to number of operations which pass through the detection area within a predetermined period, and the receiving side control circuit controls opening and closing of the switch according to the number of operations which pass through the detection area. ### Claim 10 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the non-contact sensor has an outer detection area around the beam-shaped detection area and detects the moving body when the moving body is detected in the beam-shaped detection area and in the outer detection area. ### Claim 11 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the non-contact sensor and the transmission side control circuit are capable of detecting a distance of the moving body and generates generates the detection signals corresponding to the distance, and the receiving side control circuit controls opening and closing of the switch according to the distance. ### Claim 12 (depends on 11) A wireless non-contact switch for automatic doors of claim 11, wherein the non-contact sensor and the transmission side control circuit use triangulation method to detect the distance. ### Claim 13 (depends on 11) A wireless non-contact switch for automatic doors of claim 11, wherein the non-contact sensor and the transmission side control circuit use time-of-flight method to detect the distance. ### Claim 14 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the non-contact sensor comprises an image sensor and an image analyzing circuit which detects the moving body in the detection area from image data output by the image sensor. ### Claim 15 (depends on 1) A wireless non-contact switch for automatic doors of claim 1, wherein the pseudo-touch area signs comprise a plurality of plates which can be installed on the wall surface.
