ABSTRACT:
The present invention relates to a digital indication type measuring apparatus comprising a main body of the measuring instrument such as slide calipers, incorporating therein a data processing circuit for digitally indicating measured data and a printer detachably connected to the main body of the measuring instrument. The connection between the main body of the measuring instrument and the printer is effected by a jack provided on the main body of the measuring instrument and a connector provided at the forward end of a cord extending from the printer. A switch for outputting the measured data to the printer is provided on the connector, whereby it becomes possible to use the main body of the measuring instrument such as the slide calipers as a single component or to print the measured data as necessary, so that the functional effect of the measuring instrument can be expanded.
