Abstract: Provided is a comparator including: a substantially U-shaped frame; an anvil supported at one end of the frame in an advanceable and retractable manner; a spindle supported at another end of the frame coaxially with the anvil in an advanceable and retractable manner; a measurement unit that measures the advancement and retraction of the anvil; and a display unit that displays a measurement result of the measurement unit. The measurement unit includes: an anvil contact portion that rotates around a support shaft in accordance with the advancement and retraction of the anvil; an interlocking portion that is formed to have a length greater than the length of the anvil contact portion, is supported so as to be rotatable around the support shaft, and is coupled to the anvil contact portion; and a detection unit that detects a displacement of rotation of the interlocking portion.

Abstract: There is provided a method for controlling a small-sized adjustable measuring force measurement device capable of appropriately setting the origin.A central control unit changes an operation mode to an origin setting mode in response to predetermined mode changing operation. The central control unit sets a counter value of an encoder to zero as an origin when a measuring force detecting means detects that a movable member is brought into contact with an object to be measured at a predetermined pressure in the origin setting mode.

Abstract: An external device is configured to be detachably attached to a measuring instrument via a connector. The external device includes a connector part, an external device body part and a movable connection part. The connector part has a connection terminal. The external device body part has a display part on a side surface of the external device body part. The movable connection part is configured to connect the connector part with the external device body part. The movable connection part is a biaxial rotation hinge having two pivot axes which are in a twisted position relationship with respect to each other.
