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.

An apparatus reads a value measured with an analog measuring tool. The apparatus includes an imaging unit for obtaining a captured image of the analog measuring tool that is indicating a measured value, a retaining unit for retaining a 3D model of the analog measuring tool, a matching unit for specifying a 3D model matching the captured image, a guidance unit for outputting guidance information for correcting orientation of the analog measuring tool based on the matched 3D model, a reading unit for reading the measured value from the captured image to generate a measurement result, and an output unit for outputting the measurement result.

A digital measurement instrument with excellent environmental durability and at least a conventional level of usability including a main scale, a slider movable relative to the main scale, a displacement sensor configured to detect displacement or position of the slider in relation to the main scale, and a control circuit. The control circuit controls change between a normal measuring mode and an origin setting mode. The control circuit also sets and stores a first area, the first area being a preset predetermined range outside of a measurement range. The control circuit also changes operation mode from the normal measuring mode to the origin setting mode when the slider is detected to have stopped within the first area for a consecutive predetermined period of time. Additionally, the digital calipers are provided with no mechanical push button switches.

A measuring instrument is configured to detect a displacement of a contact point provided to be movable and to digitally display a measured value on a display unit provided on an outer surface of a case. The measuring instrument includes an input unit. The input unit is provided on the outer surface of the case and is configured to allow a user to input to the input unit through a manual operation. The input unit includes a sensor which is configured to detect an amount of operation and a speed of operation. The amount of operation is converted into a conversion value in view of the speed of operation and then is displayed on the display unit.

A spindle drive comprising a threaded spindle with an external thread, a spindle nut with an internal thread that is in engagement with the external thread of the threaded spindle, characterized in that the external thread of the threaded spindle has multiple threaded areas that are separated from each other by first flattenings on their circumference extending in the longitudinal direction, and the first flattenings have guide areas that abut the core diameter of the internal thread of the spindle nut.
