Problems solved by technology

[0005] In addition, in recent years, an electronic level that can simultaneously measure a plurality of scales within a desired range has been proposed. However, the measurable range cannot be confirmed with the collimator of the existing electronic level, and the function of the electronic level cannot be adapted.

Abstract

An electronic level which is arranged to receive reflected light from a pattern marked on a staff (5) and to determine the height of the sighting position and the distance to the staff, comprises an electronic level main unit (2), a sighting optical system (15) accommodated in the electronic level main unit (2) for sighting the staff (5) and a sighting device (3) provided on an upper surface of the electronic level main unit (2). The sighting device (3) can be sighted in at least in two directions, and the angle (¸) formed by the two directions is equal to or approximately equal to the field angle of the sighting optical system (5).

Description

technical field [0001] The present invention relates to an electronic level that converts a pattern image of a scale into an electric signal, and obtains a sighting height and a distance to the scale from the obtained electric signal. Background technique [0002] A spirit level is a measuring device for measuring height differences. A conventional spirit level is a measurement device in which a worker points a telescope at a scale installed at a measurement target point and visually reads a numerical value drawn on the scale. Therefore, there is a possibility that the operator reads the scale of the scale incorrectly. [0003] In order to prevent misreading the scale of the scale, electronic levels and scales for electronic levels are being developed as follows, that is, aiming at the scale, receiving light from the drawn pattern with a light receiving element, converting it into an electrical signal, calculating the position, and displaying it as a numerical value. [000...
