摘要： According to one embodiment, a recording medium is a recording medium in a card form. The recording medium includes a substrate, and a color development layer laminated on the substrate, and provided with a line for security that extends along a lamination surface of the substrate from an end face of the recording medium, such that presence or absence of the line for security is optically identifiable at the end face. It is thus provided a recording medium that can easily prevent falsification with a simple structure, and allows authenticity determination to be performed relatively easily.

摘要： According to one arrangement, a ranging apparatus includes a light source (23), a movable mirror (251), a light sensor (26), a measurement circuit (27), and a first control circuit (21). The movable mirror reflects each of first and second laser lights. The second laser light corresponds to the first laser light reflected by an external subject. The light sensor detects the second laser light reflected by the movable mirror. The measurement circuit measures a distance to the subject based on a timing of emission of the first laser light by the light source and a timing of detection of the second laser light by the light sensor. The first control circuit changes an emission direction of the first laser light based on a first signal from outside.

摘要： According to one arrangement, a ranging device includes a light source, an optical sensor, a measurement circuit, and a control circuit. The light source is configured to emit first laser light. The optical sensor is configured to detect second laser light corresponding to the first laser light reflected by an external subject. The measurement circuit is configured to measure a distance to the subject based on a timing at which the light source emits the first laser light and a timing at which the optical sensor detects the second laser light. The control circuit is configured to control a number of ranging points indicating a number of distances measured per unit time by the measurement circuit in a predetermined area within an angle of view of the ranging device.
