Abstract
Sensor(s) may be such that light-projecting component(s), at which light is irradiated from one or more light-projecting elements by way of lens group(s); and light-receiving component(s), at which at least a portion of light irradiated from such light-projecting component(s) is incident on one or more light-receiving elements by way of lens group(s) after having been reflected, are arrayed therein. Lens group(s) is/are divided into a plurality of lens sets comprising a plurality of lenses. A plurality of lens sets are arranged so as to be inclined in V-shaped fashion such that a plurality of lenses occupy respectively symmetric locations.
Claims8
A sensor capable of detecting of one or more objects, the sensor comprising:
- one or more light-projecting elements;
- one or more condenser members;
- and
- one or more light-receiving elements;
- at least one of the light-projecting element or elements irradiating at least a portion of a plurality of protected zones with light by way of at least one of the condenser member or members;
- light reflected from at least a portion of the protected zones being incident on at least one of the light-receiving element or elements by way of at least one of the condenser member or members;
- at least a portion of the light-projecting element or elements and at least a portion of the light-receiving element or elements being disposed at one or more focus or foci of at least a portion of the condenser member or members;
- wherein when at least one of the protected zones which is proximate to at least a portion of the light-projecting element or elements and/or at least a portion of the light-receiving element or elements is taken as reference, at least one edge, on at least one side toward at least a portion of the light-projecting element or elements and/or at least a portion of the light-receiving element or elements, of at least one of the protected zones which is located in at least one direction extending laterally from the at least one reference protected zone is formed so as to be more or less collinear with at least one edge, on at least one side toward at least a portion of the light-projecting element or elements and/or at least a portion of the light-receiving element or elements, of the at least one reference protected zone.
