Abstract

The invention provides an image forming apparatus. The image forming apparatus of the invention comprises a first detection portion, a first signal generation portion, a second detection portion, a second signal generation portion, a storage portion, and a recognition portion. The first signal generation portion receives the output of the first detection portion detecting the upper half of the human body and generates a first signal. The second signal generation portion receives the output of the second detection portion detecting the lower half of the human body and generates a second signal. The storage portion stores discrimination data for recognizing whether a human is approaching or crossing. The recognition portion recognizes whether the human is approaching or crossing based on the first and second signals and the discrimination data. Based on the invention, the direction of movement of the human with respect to the image forming apparatus can be recognized.

Description

technical field [0001] The present invention relates to an image forming device that recognizes the movement of a human body using heat (infrared rays) emitted from a human body (a human or also called a user). Background technique [0002] Conventionally, the presence or absence of a person in a detection area has been detected using an infrared sensor that detects infrared rays emitted by a person. For example, the detection result of the presence or absence of a human body is used for security and the like. For example, a detection device that detects a human body using two sensor units as shown below is described. [0003] Specifically, there is known a passive infrared human body detection device, which has two level detection circuits and a human body detection circuit. The level detection circuit has two sensor units composed of a light receiving element and an optical system. One sensor unit is arranged so that the light receiving direction faces the upper body of ...
