Abstract: A caliper measurement force detecting device includes a fixed unit that is securely attached to a slider so as not to displace relative to the slider; a movable unit that is provided to allow a slight displacement relative to the fixed unit along a direction parallel to a displacement direction of the slider; and pressure detectors that are arranged between the fixed unit and the movable unit and are provided so as to detect pressure applied in the direction parallel to the displacement direction of the slider. The movable unit includes an alternative finger hook that is arranged near a finger hook of the slider and serves as an operator that pushes and pulls the slider instead of the finger hook of the slider.

Abstract: A connection unit for connecting an external device to a main device is provided. A connection unit 100 includes a main body part 200 including a main connector terminal 220 to be connected to a connection port of a main device, a sub body part 300 including a sub connector terminal 320 to be connected to a connection port of an external device, and an electric cable 500 electrically connecting the main connector terminal 220 to the sub connector terminal 320. The main body part 200 and the sub body part 300 are united by engaging by an engaging means that is engageable and disengageable, and vary a relative position between the main body part 200 and the sub body part 300 by disengaging by the engaging means. The external device is electrically connected to the main device and is simultaneously attached to the main device by connecting the main device to the external device with the connection unit 100 while the main body part 200 and the sub body part 300 are united.
