Abstract

A measuring device is provided that suppresses wrinkle generation. The measuring device includes a body and a cover to be attached to the body. The body includes a grip and also includes a sensor portion. A fixation portion is formed at an upper surface of the grip. The sensor portion includes a measuring portion disposed at a distal end thereof and a connection portion that connects between the measuring portion and the grip. A sensor is disposed in the measuring portion. In the measuring device, an angle between (1) a reference plane comprising the measurement surface and (2) a tangent line drawn between the fixation portion and the body as viewed in a direction that is perpendicular to the longitudinal direction and that is parallel to the reference plane, is 50 degrees or less.

First claim

The invention claimed is:

1. A measuring device comprising:
a body;
a sensor portion and a grip disposed in a longitudinal direction of the body;
a sensor disposed at an end portion of the sensor portion, the end portion being positioned opposite to the grip; and
a measurement surface of the sensor exposed at the sensor portion,
wherein a fixation portion, which a cover for covering the sensor is fixed to, is disposed at a surface of the body opposite to a surface thereof at which the measurement surface is exposed,
wherein the cover comprises a cover member and a support member, and the cover is attached to the body such that the cover member covers a measuring portion positioned at a distal end of the sensor portion, the measuring portion including the measurement surface,
wherein when the cover member is installed over the measuring portion, and the support member applies uniform tensile forces to the cover member that prevents wrinkle generation, and
wherein an angle between a reference plane comprising the measurement surface and a tangent line drawn between the fixation portion and the body as viewed in a direction that is perpendicular to the longitudinal direction and that is parallel to the reference plane, is 50 degrees or less.
