The second surface 34 is formed with a slit 36 for fixing a measuring instrument to be described later. The slit 36 is formed along the standing direction of the second surface 34 of the standing portion 30.

  In the slit 36 formed in the second surface 34, one end edge in the longitudinal direction is aligned with the position of the center point O of the cross line of the guide body 16 (which is also the position of the reference point provided on the building side). , Formed in a direction orthogonal to the surface of the rotating unit 20. When the optical axis height position (measurement reference height) of a laser range finder 60 as a measuring instrument to be described later is shifted from a reference point provided in the building, the laser range finder 60 or the laser range finder 60 The value of the deviation amount may be input as a correction value or stored in the storage means in advance in coordinate calculation software that executes coordinate calculation in the building based on the measurement data obtained by the above. Further, a scale 38 indicating an offset (separation distance) from the mounting surface of the base portion 10 along the longitudinal direction of the slit 36 is displayed on the slit 36. The scale 38 in the present embodiment is pasted with the scale seal aligned with the second surface 34, but the scale 38 may be engraved on the surface of the second surface 34.

Is formed so as to follow a plane orthogonal to the reference point and passing through the reference point. Further, when the standing portion bolt 26 is inserted into the housing bolt hole 34A so that the second surface 34 of the standing portion 30 is overlapped with the rotating portion 20, the first surface 32 of the standing portion 30 is the base portion. A bolt hole 34A for storage is formed at a predetermined position so as to be positioned outside the outer peripheral edge position on one side of the base portion 10 without interfering with the base 10 (see FIG. 5).

  By adopting such a housing bolt hole 34A, as shown in FIG. 5, it is possible to greatly reduce the height dimension of the measuring instrument holder 50 during housing. This is advantageous in that the carrying device 50 for the measuring instrument can be carried very easily.

  In the present embodiment, the height position of the horizontal plane including the center point O of the cross line of the guide body 16 and the upper surface height position of the second surface 34 are the same height position. For this reason, when a distance measuring device (laser rangefinder 60) described later is placed on the second surface 34, the height position of the optical axis of the laser rangefinder 60 is the height position of the reference point set in the building. Higher than. For this reason, when the laser rangefinder 60 has an optical axis correction function, an optical axis deviation value for correcting the height position of the optical axis is input to the laser rangefinder 60. When the laser range finder 60 does not have an optical axis correction function, an optical axis deviation value is input to coordinate calculation means for calculating coordinates based on measurement data (distance data and angle data) of the laser range finder 60. Then, the coordinate calculation based on the measurement data in consideration of the deviation value of the optical axis may be executed.

The reference line display device 100 can display various reference lines. In the reference line display device 100, the installation surface height only needs to be known, so the laser marking device 90 only needs to be placed on the second surface 34 of the upright portion 30, and the laser to the slit 36 can be obtained. It is not essential to lock the inking device 90.

(Second Embodiment)
In the present embodiment, the same reference numerals as those used in the first embodiment are used for the configuration described in the first embodiment, and a detailed description thereof is omitted here. As is apparent from FIG. 9, the measuring instrument holder 50 according to the present embodiment is also provided with a leveler mounting hole 39 (see FIG. 10) in the standing portion 30, and in addition to the rotating portion 20. The configuration is different in that the mounting position of the part 30 is lower than the measuring instrument holder 50 in the first embodiment.

  Specifically, the upper surface height position of the second surface 34 of the standing part 30 attached to the rotating unit 20 is higher than the height position (center point height position) of the horizontal plane including the center point O of the guide body 16. Is also located at a position shifted by a predetermined height (here, a position shifted downward). The difference in height between the horizontal line including the center point O of the guide body 16 and the height of the upper surface of the second surface 34 is the optical axis OA of the laser rangefinder 60 when the laser rangefinder 60 is placed on the second surface 34. The height position (see FIG. 10) is set to be the height position of the horizontal line including the center point O of the guide body 16.

  The amount of deviation between the bottom height position of the laser rangefinder 60 and the height position of the optical axis OA of the laser rangefinder 60 is a unique value depending on the manufacturer and model of the laser rangefinder 60. A plurality of types of uprights 30 corresponding to the manufacturer and model of the laser rangefinder 60 are prepared in advance, and appropriate uprights 30 are appropriately selected and used for the laser rangefinder 60 to be used. You may do it.

  Furthermore, the use bolt hole 32A is long in the height direction so that the upper surface height position of the second surface 34 of the upright portion 30 with respect to the height position of the horizontal line including the center point O of the guide body 16 can be adjusted. A configuration formed in a long hole shape can also be employed. In this way, by making the height position of the optical axis OA of the laser rangefinder 60 coincide with the height position of the horizontal line including the center point O of the guide body 16, correction as in the first embodiment is performed. This is advantageous in that it is not necessary to input a value.

  Moreover, in this embodiment, it has the leveler LK for leveling the 2nd surface 34 of the standing part 30 which is a mounting surface of the laser rangefinder 60. FIG. It is advantageous in that the laser rangefinder 60 can be calibrated by making the second surface 34 of the upright portion 30 a horizontal plane by the leveler LK. As shown in FIGS. 9 and 10, the levelizer LK in the present embodiment includes two first perforated plates L <b> 1, one second perforated plate L <b> 2, and a downward swing W.

  The levelizer LK attaches one end side of the two first perforated plates L1 to a leveler mounting hole 39 (see FIG. 10) drilled in the first surface 32 of the upright portion 30, and crosses the other end side with each other. The 2nd perforated plate L2 arrange | positioned and arrange | positioned in the position on the extended line of the perpendicular | vertical line containing the center point O of the guide body 16 and two 1st perforated plates L1 are connected in an intersection position. In the link mechanism thus formed, the downward swing W is locked to the second perforated plate L2 at a position vertically below the connecting position between the first perforated plate L1 and the second perforated plate L2. Is. Here, the first perforated plate L1 and the second perforated plate L2 having a plurality of holes formed at predetermined intervals are employed. However, both the first perforated plate L1 and the second perforated plate L2 are at least 2. It is sufficient if two holes are formed.

  When the second surface 34 of the standing portion 30 can be made horizontal, the levelizer LK is removed. After the laser range finder 60 is calibrated using the second surface 34 of the upright portion 30 that is a horizontal plane, the laser range finder 60 is calibrated as shown in FIG. 10 in the same manner as in the first embodiment. The distance measuring device 70 is fixed to the surface 34. The distance measuring device 70 in the first embodiment and the present embodiment measures not only the distance to the measurement target point but also the angle. The tablet terminal 200 is mounted on the tablet terminal mounting body 210 attached to the building at a position below the laser rangefinder 60 of FIG.

  The tablet terminal mounting body 210 has a first plate 212 parallel to the base portion 10, a second plate 214 parallel to the second surface 34 of the standing portion 30, and a free end of the second plate 214 facing the first plate 212 side. The bent portion 216 is formed. The tablet terminal 200 is mounted on the tablet terminal mounting body 210 formed in this way, and the tablet terminal 200 and the laser distance measuring device 60 are wirelessly communicated, so that the measurement result by the laser distance measuring device 60 is transferred to the tablet terminal 200. Can be sent. It should be noted that the tablet terminal mounting body 210 is not a form in which a plurality of members are integrated as in this embodiment, but may be formed by processing a single sheet metal.

  Since coordinate calculation software is installed in the tablet terminal 200, if the measurement data by the laser rangefinder 60 is immediately calculated by the coordinate calculation software and the calculation result is displayed on the display unit of the tablet terminal 200, the laser distance measurement is performed. The coordinates in the building can be surveyed sequentially while confirming the measurement result by the ritual 60. In addition, since the internal structure of the tablet terminal 200 is well-known (it has a memory | storage part, CPU, and an output part), description about a detailed structure here is abbreviate | omitted.

  As shown in FIG. 10, the laser rangefinder 60 is attached in a state of being biased toward one end side in the width direction, not in the center portion in the width direction of the second surface 34 of the upright portion 30. For this reason, it is assumed that the second surface 34 of the standing portion 30 is inclined to one side as shown in FIG. 11 due to its own weight. Therefore, as shown by a broken line in FIG. 11, it is preferable to dispose a detachable counterweight CW at the end position of the second surface 34 opposite to the side on which the laser rangefinder 60 is attached. By providing such a counterweight CW, an operation for preventing the tilt of the second surface 34 by the user is unnecessary or only a slight force is required.
