Device for both visual and audible information with human body detecting device

Abstract

Abstract PURPOSE:To inform prescribed information for one visitor alone from the beginning by starting an audible device or a visual device by a signal, obtained from a human body detecting device, consisting of various kinds of sensors or mechanical switches, etc. CONSTITUTION:The automatic human body detecting device Det, using the sensors of an ultrasonic type, an infrared type, an electromagnetic wave type and an electrostatic type, and the mechanical switches like a mat switch, is provided, and when the device Det detects a human body, a hold circuit H and information presenting devices Audio and Video are started, and operate as shown by a line O. While the circuit H operates, a next signal is masked even if it is transmitted in, and the prescribed information is not newly presented at that point of time, but when the next signal is generated as shown by a broken line, within a period, tracing back by holding time DELTAH from the finish time O of the information, the information of next time is newly presented from the point of time when the presentation of the information of the first time is finished. Therefore, the prescribed information can be presented from the beginning for one visitor when the approaches to a shop front.
