Abstract

An output-attached measuring instrument has: a measuring instrument body (

1) having a circuit board (

14) for processing a measurement signal from a sensor as a measurement data, an output electrode (

15) for outputting the measurement data, and a connector hole (

17) in communication with the output electrode and opening to an outer surface; and a connection cable (

30) having a connector (

32) capable of attaching to and detaching from the connector hole on an end thereof for transmitting the measurement data obtained by the measuring instrument body to an external device, the connector having a projection (

33) capable of being plugged to and unplugged from the connector hole and a connector terminal (

34) exposed on a surface thereof, where an elastic connector (

20) having am electro-conductive portion for electrically connecting the connector terminal and the output electrode is accommodated in a space of the connector hole of the measuring instrument body and the elastic connector shuts the connector hole when the projection is unplugged from the connector hole and electrically connects the connector terminal and the output electrode through the electro-conductive portion when the projection is plugged into the connector hole.

Claims

1. An output-attached measuring instrument, comprising:

2. The output-attached measuring instrument according to claim 1, the connector hole comprising: a perpendicular channel perpendicular to the circuit board; and an opening channel bent from an end of the perpendicular channel and opening toward the outer surface of the measuring instrument body,

3. The output-attached measuring instrument according to claim 2, wherein an elastic sealing member is provided along the periphery of the opening channel on the outer surface of the measuring instrument body, and

4. The output-attached measuring instrument according to claim 1, wherein a plurality of the electro-conductive portions connecting a surface opposing the opening channel and a surface opposing the output electrode are provided to the elastic connector sandwiching a non-electro-conductive portion therebetween.

5. The output-attached measuring instrument according to claim 1, wherein the sensor is a caliper having a main scale with a first measurement jaw provided at an end in the longitudinal direction and a slider movable in the longitudinal direction of the main scale and having a second measurement jaw to be in contact with the workpiece together with the first measurement jaw, and

6. An output-attached measuring instrument connectable to a connection cable having a connector with a connector terminal and the connector having a projection, the output-attached measuring instrument comprising:

7. The output-attached measuring instrument according to claim 6, the connector hole comprising: a perpendicular channel perpendicular to the circuit board; and an opening channel bent from an end of the perpendicular channel and opening toward the outer surface of the measuring instrument body,

8. The output-attached measuring instrument according to claim 7, wherein an elastic sealing member is provided along the periphery of the opening channel on the outer surface of the measuring instrument body, and

9. The output-attached measuring instrument according to claim 6, wherein a plurality of the electro-conductive portions connecting a surface opposing the opening channel and a surface opposing the output electrode are provided to the elastic connector sandwiching a non-electro-conductive portion therebetween.

10. The output-attached measuring instrument according to claim 6, wherein the sensor is a caliper having a main scale with a first measurement jaw provided at an end in the longitudinal direction and a slider movable in the longitudinal direction of the main scale and having a second measurement jaw to be in contact with the workpiece together with the first measurement jaw, and
