摘要： PURPOSE:To obtain an alignment measuring instrument which can easily make alignment measurement required at the time of installing reference instrument for laying down railway tracks and a fitting jig which can easily fit the alignment measuring instrument to the reference points. CONSTITUTION:A plurality of reference instruments are installed along a proposed railway track laying line and, at the same time, a laser light source 100 is installed to the reference point corresponding to one end of a chord for measuring the alignment of the reference points and a target 200 is installed to the reference point corresponding to the other end of the chord, with chord being constituted of a laser beam 101 emitted from the light source 100. An alignment measuring scale 300 protruding from the reference point is provided in the middle of the chord and, by receiving the laser beam 101 by means of a photoreceptor attached to the alignment measuring scale, an alignment- measured value is obtained.

摘要： PURPOSE:To enable the setting of a standard device by an unskilled worker by a method wherein an index provided on a main scale is set at a position corresponding to a sight distance value from a reference line and an adjusting means of the standard device is operated to make the position of the index match the reference line set with a transit. CONSTITUTION:First, a reference line is set using a transit and a target, then, a mating section 31 is mated with the reference target 19 of a standard device 10 to be set and the position of an upper/lower position adjusting means 32 is turned centered on the reference target 19 to change the direction of a main frame 30. Then, a collimation is made with the transit to make an index 33 match a sub index 33F and the main frame 30 is set in the direction orthogonal to the reference line. Then, the main frame 30 is leveled by the operation of a knob 32beta and the distance from the index 33 to the reference target 19 is made to coincide with a given length of a sight distance. Then, the index 33 is collimated with the transit and a screw shaft 13 is turned so that the index 33 matches a vertical collimation line of the transit. When a deviation between the both is down to zero, the setting of the sight distance is completed.
