Claims

[Scope of utility model registration request]

(1) A line sensor in which a plurality of light-receiving elements are vertically arranged within the same length as a predetermined reference length on the scale of the leveling staff from a predetermined reference position is installed on the front of the detector box that is slidably attached to the leveling staff, and A position detection circuit is connected to each light-receiving element of the sensor, which detects the position of the light-receiving element when it receives horizontal light flux from a two-dimensional level, and outputs the length from that position to the reference position as a signal. The detector box is provided with a display that digitally displays the output signal of the position detection circuit as a numerical value of length, and a mark is placed on a horizontal extension line passing through the reference position on a portion adjacent to the scale surface of the leveling rod. What is claimed is: 1. A two-dimensional level luminous flux receiving and detecting device, characterized in that it is provided with an index of

(2) The detector box is equipped with auxiliary sensors each having a plurality of light-receiving elements arranged vertically at the top and bottom of the line sensor. , a two-dimensional level light beam receiving and detecting device according to claim 1, characterized in that the device is provided with a display that displays an instruction to move the detector box upward or downward. .

(3) The detector box is provided with an acoustic alarm that emits a sound when the light receiving element of the line sensor receives a horizontal light beam from a two-dimensional level. 2. A two-dimensional light beam receiving and detecting device according to item 1 or 2.

(4) The detector box is provided with an acoustic alarm that emits a sound when the light receiving element of the auxiliary sensor receives a horizontal light beam from a two-dimensional level. 2. A two-dimensional light beam reception and detection device according to item 2, item 2, or item 3.
