Digital indication type measuring apparatus
First Claim
1. In a digital indication type measuring instrument which is compact in size and is portable, said measuring instrument having scale means and a slider means movably mounted on said scale means, a data processing circuit means and a digital display means provided on said slider means and movable therewith, the improvement comprising wherein said slider means has a body and an electrical jack means connected in electrical circuit to said data processing circuit means;
- and wherein a connector means is adapted to be detachably mounted on said electrical jack means, said connector means including an elongated cable and a body part secured to one end of said cable, the other end of said cable being connected in circuit with a recording means separate from said scale means and said slider means, said body part having a data output switch means thereon easily operable by a finger of a user of said measuring instrument for providing a data output command to said data processing circuit means upon operation thereof to effect the selected transference of data in said data processing circuit means and displayed on said digital display means to said recording means, a removal of said body part and said data output switch means thereon from said electrical jack means for purposes of detaching said recording means from connection with said data processing circuit means still enabling a reading of said data in said data processing circuit means on said digital display means.

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.
