Abstract: A small-sized measuring device includes a position detector that is provided on a main body and detects the position of an object to be measured, a timer that measures time, and a central control unit that controls overall operation. The central control unit accepts a base-point setting standby time set by a user and stores the base-point setting standby time. The central control unit measures elapse of the base-point setting standby time after accepting an instruction to start measuring time from the user, performs a base-point setting step of setting the position of the object to be measured detected by the position detector as a base point after the base-point setting standby time has elapsed, and then measures the position of the object to be measured as a relative position from the base point.

Abstract: A small-sized measuring device includes a position detector that is provided on a main body and detects the position of an object to be measured, a photosensor, and a central control unit that controls overall operation. The photosensor is configured to function at least as an input device configured to accept a base-point setting instruction from the user. The central control unit, when accepting the base-point setting instruction from the user through the non-contact input sensor, performs a base-point setting step of setting the position of the object to be measured detected by the position detector as a base point, and performs a measurement step of measuring the position of the object to be measured as a relative position from the base point.

Abstract: There is provided a measuring device that is inexpensive and easy to use, yet provides sufficient accuracy and resolution in continuous scanning measurement to measure workpiece surfaces. A dial gauge includes a spindle provided to be movable reciprocatively in an axial direction through a main body case. The main body case includes a stem provided to protrude from a side face of the main body case. A ball bearing that bears the spindle is provided inside the stem. A workpiece and the dial gage are relatively moved while a contact point at the tip of the spindle is in contact with the surface of the workpiece, and continuous scanning measurement is performed to measure irregularities of the surface of the workpiece or the amount of runout of the rotating workpiece.
