To enable scanning using measurement light with a small-sized displacement measuring apparatus. The displacement measuring apparatus includes a MEMS mirror for scanning using measurement light that is output from a light projection lens. The light projection lens has a focus position, at which the measurement light is condensed, at the MEMS mirror or in the vicinity of the MEMS mirror on an optical axis of the measurement light. The measurement light that is reflected at the MEMS mirror spreads in a strip-shaped manner as the measurement light comes close to a measurement region.

Displacement measuring apparatus

There is provided a transmissive dimension measuring device in which a user can intuitively and easily adjust optical axes of a projector and an optical receiver, and in which a suitable action can be immediately taken when contamination is attached to a light projecting surface of the projector and a light receiving surface of the optical receiver. An incident light position display unit provided on the optical receiver expresses a light projecting spot in a pseudo manner by making an LED corresponding to an incident light position turn on, the light projecting spot being incident on the optical receiver arranged with a predetermined interval to the projector which projects light. The incident light position display unit is provided on an upper surface side opposite to a bottom surface that is a surface on which the optical receiver is installed on a base.

Transmissive dimension measuring device

This invention provides a sensor attachment device that can be easily attached and detached, a sensor and a light emitting device for a photo-electrical sensor. By downward displacement of an operation member after tip ends of a pair of locking hooks are locked to a sensor main body by inserting the sensor main body into an insertion opening with second regions of a pair of facing surfaces respectively facing toward external surfaces of central portions of the pair of locking hooks, the central portions of the pair of locking hooks can be pressed inwardly by first regions of the pair of facing surfaces, thereby fixing the sensor main body to a holding member. Accordingly, the attachment of the sensor main body is easy in comparison with the conventional configuration in which a nut is screwed onto the sensor main body, then rotated and fastened.
