Small-sized measuring device and operating method of the same

1 . A small-sized measuring device comprising:

a main body;

a position detector provided on the main body and configured to detect a position of an object to be measured by contact or non-contact;

a non-contact input sensor configured to sense an instruction of a user in a non-contact manner; and

a central control unit configured to control overall operation, wherein

the non-contact input sensor is configured to function at least as an input device configured to accept a base-point setting instruction from the user, and

the central control unit is configured:

to perform, when accepting the base-point setting instruction from the user through the non-contact input sensor, 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

to perform a measurement step of measuring the position of the object to be measured as a relative position from the base point.

2 . The small-sized measuring device according to claim 1 ,

wherein the non-contact input sensor is a photosensor.

3 . The small-sized measuring device according to claim 1 ,

wherein the non-contact input sensor is a human detecting sensor.

4 . The small-sized measuring device according to claim 1 ,

wherein the non-contact input sensor is a non-contact touch panel.

5 . The small-sized measuring device according to claim 1 , further comprising a timer configured to measure time, wherein

the central control unit is configured:

to measure a duration time of operation performed by the user through the non-contact input sensor; and

to perform predetermined mode switching according to the duration time of operation.

6 . The small-sized measuring device according to claim 1 ,

wherein the central control unit is configured:

to store types of input instructions acceptable through the non-contact input sensor while performing the measurement step;

to accept an input instruction from the user through the non-contact input sensor while performing the measurement step; and

to perform mode switching according to the input instruction.

7 . The small-sized measuring device according to claim 1 ,

wherein the position detector is a detector having a single measurement axis.

8 . The small-sized measuring device according to claim 1 ,

wherein the position detector comprising:

a movable member provided on the main body to be movable forward and backward and to be brought into contact with the object to be measured; and

an encoder configured to detect a position of the movable member.

9 . The small-sized measuring device according to claim 1 ,

wherein the small-sized measuring device is a portable small-sized measuring device to be carried in a hand of the user and to be attached to a stand to maintain a relative posture or a relative position with respect to the object to be measured.

10 . The small-sized measuring device according to claim 1 , further comprising a timer configured to measure time,

wherein the central control unit is further configured:

to accept a base-point resetting standby time set by the user and store the base-point resetting standby time; and

to repeat the base-point setting step at intervals of the base-point resetting standby time while performing the measurement step.

11 . The small-sized measuring device according to claim 10 ,

wherein the base-point resetting standby time is input through the non-contact input sensor, and

the central control unit is configured to store the base-point resetting standby time input through the non-contact input sensor.

12 . An operating method of a small-sized measuring device according to claim 1 , the method comprising:

inputting by a user, after completing adjustment of a relative position or a relative posture between an object to be measured and the small-sized measuring device, a base-point setting instruction through the non-contact input sensor.
