置。[Claims for Utility Model Registration] 1. (1) It has a light projecting means consisting of a light emitting element and a light projecting lens, and receives light emitted from the light projecting means and reflected from a subject, and reaches the subject. A distance detection device for measuring the distance of a subject, comprising: an imaging means for receiving reflected light from the object; a light receiving element disposed on the imaging side of the imaging means; a light-shielding member that travels in correlation with the distance to the subject and has an effective width to cover the light-receiving element; and a detection circuit that detects a change in photoelectric output of the light-receiving element caused by activation of the light-shielding member. A distance detection device comprising: (2) Utility Model Registration In the item described in claim 1, the light shielding member is in a position where it does not shield any part of the light receiving element before starting its operation, and scans the surface of the light receiving element during the process. The distance detecting device is configured to cover the entire light receiving element at the end of operation, and includes a detection circuit for detecting when the photoelectric output of the light receiving element decreases during scanning. -(3) Utility model registration In the device described in claim 1, the light-shielding member is in a position covering the entire light-receiving element before the start of operation, and while scanning the surface of the light-receiving element during operation. The distance detecting device is configured such that no part of the light receiving element is covered at the end of scanning, and includes a detection circuit for detecting a point where the photoelectric output of the light receiving element rises from zero during scanning. (4) Scope of Utility Model Registration Claims Paragraph 1, Paragraph 2, or Paragraph 3
2. The distance detection device according to item 1, wherein the light emitted from the light emitting element is pulse modulated light.
