In this case, the thickness of the other side parallel surface 14 is 10 mm or more, which is thicker than that of a general caliper. Therefore, by applying the other side parallel surface 14 to the outer surface of the object to be measured 105, the length direction of the object to be measured 105 is obtained. Can be used orthogonally to.

Further, the surface 102 of the face material 101 can be marked with an angle of 45 degrees with the side surface 103.

Further, since the sandwich angle between the oblique surface 15 which is the oblique positioning contact portion and the other side parallel surface 14 which is the parallel positioning contact portion is 45 degrees, it is possible to perform highly versatile 45-degree marking. Since the other side parallel surface 14 can be formed longer in the width direction of the slider main body 12 than the one side parallel surface 13, the other side parallel surface 14 can be stably brought into contact with the side surface 103 or the like.

Further, since the mounting recess 33 recessed downward is provided on the upper surface of the groove bottom portion 22, the leaf spring 34 can be slid into the sliding groove by inserting the lower portion of the metal leaf spring 34 which is an elastic sliding body into the mounting recess 33. It can be attached to the attachment portion 25 facing the inside of 21. Further, since the hexagon nut 37, which is the female screw portion into which the fixing screw 35 is screwed, is fixed to the mounting portion 25 in a non-rotating state, compared with the case where the female screw portion is formed on the mounting portion 25 made of synthetic resin, The screwing operation of the fixing screw 35 becomes stable for a long period of time. Further, since the positioning receiving holes 42, 42 into which the insertion boss portions 41, 41 are inserted are formed on the upper surface of the mounting lower portion 32, the mounting upper portion 31 and the mounting lower portion 32 can be easily assembled. Further, as shown in FIG. 3, when used like a caliper, the leaf spring 34 comes into contact with the outer edge portion 2A, so that a gap may be generated between the groove wall portion 26 and the inner edge portion 2B. Instead, the dimensions of the object 105 to be measured can be accurately read by using the other side parallel surface 14 of the other side parallel wall portion 14K and the scale 5 of the inner edge portion 2B.

FIG. 12 shows Example 2 of the present invention, the same parts as those in Example 1 are designated by the same reference numerals, and the description thereof will be omitted in detail. The figure shows an example in which the vernier scale 51 is provided on the ruler slider 11.

Specifically, the holding piece 27A is formed by expanding the holding piece 27 of the groove wall portion 26, and the end portion of the holding piece 27A is located on the other side parallel surface 14 and is located at the zero position of the vernier scale 51. It is 510. The vernier scale 51 is a scale obtained by dividing 19 mm into 20 parts, and is provided so as to face the scale 5 of the inner edge portion 2B of the long piece 2 so as to overlap the scale 5. The scale 5 is provided in 1 mm increments.

In FIG. 12, the zero position 510 indicates 20 mm of the scale 5, but for example, when the zero position 510 is between 20 mm and 21 mm of the scale 5, it coincides with the scale 5 of the long piece 2 in 1 mm increments. The value obtained by multiplying the value of the vernier scale 51 to be performed by 0.1 is a value of less than 1 mm. For example, if the position 516 of "6" of the vernier scale 51 coincides with the scale 5, it becomes 20.6 mm. In addition to dividing 19 mm into 20 equal parts, a vernier scale obtained by dividing 39 mm into 40 equal parts may be used, and in this case, measurement can be performed in units of 0.05 mm.

As described above, in this embodiment, the same actions and effects as those in Example 1 are exhibited.

Further, in this example, by providing the vernier scale 51, the dimension of 1 mm or less can be accurately read.

FIG. 13 shows Example 3 of the present invention, the same parts as those in the above Examples are designated by the same reference numerals, and the description thereof will be omitted in detail. The figure shows an example in which the ruler slider 11 is used for a straightedge 61 which is a ruler rod.

The straightedge 61 has one side edge portion 61A in the length direction and the other side edge portion 61B on both sides in the width direction, and has end edges 61T and 61T in the width direction at both ends in the length direction. Further, the ruler slider 11 is slidably provided on the straight scale 61.

Then, when marking the surface 102 of the face material 101 such as a plate material at a predetermined position from the side surface 103, the length direction edge portions 61T and 61T and the one-side parallel surface 13 or the other-side parallel surface 14 are at the predetermined positions. The slider body 12 is fixed to the straightedge 61 so that the parallel surface 13 on one side or the parallel surface 14 on the other side abuts on the side surface 103, and the back surface of the straightedge 61 is aligned with the front surface 102. Rulers can be made using the edge portion 61T in the length direction.

Next, when measuring the thickness of the face material 101 or the step difference of a member (not shown), the face material 101 is placed on the flat surface 104, the slider main body 12 is not fixed, and the end edge portion 2T in the length direction is described. Along with contacting the flat surface 104, the straightedge 61 is oriented vertically along the side surface 103 at right angles to the surface 102, and the one-side parallel surface 13 or the other-side parallel surface 14 of the slider body 12 is the surface 102 of the face material 101. The thickness of the face material 101 can be measured by reading the scale 5 of the straightedge 61 at the position of the parallel surface 13 on one side or the parallel surface 14 on the other side.

Next, when marking the front surface 102 of the face material 101 at an angle of 45 degrees with the side surface 103, the slider body 12 is fixed, the oblique surface 15 is brought into contact with the side surface 103, and the back surface of the straightedge 61 is formed. Can be diagonally marked along the surface 102 using the one side edge portion 61A. It should be noted that the diagonal line can be marked by using the other side edge portion 61B.

As described above, in this embodiment, the slider main body 12 provided on the straightedge 61 which is a ruler so as to be slidable in the length direction, the positioning fixing means 24 for positioning and fixing the slider main body 12 on the straightedge 61, and the slider main body 12 are provided. Since it is provided with an oblique surface 15 which is an oblique positioning contact portion provided in an oblique direction with respect to the length direction of the straightedge 61, it corresponds to each of the above-described embodiments 1, 3, 6 and 7. It has the same effect and effect.

The present invention is not limited to the present embodiment, and various modifications can be made within the scope of the gist of the present invention. For example, in the embodiment, an oblique positioning contact portion having an angle of 45 degrees with respect to the length direction of the ruler rod is illustrated, but the sandwiching angle with the other side parallel surface of the embodiment is 45 degrees (1). In addition to the angle between the side parallel surface (135 degrees), the angle between the other side parallel surface is 30 degrees (the angle between the one side parallel surface is 150 degrees) and the angle between the other side parallel surface is 60 degrees. (The angle between the parallel surface on one side is 120 degrees) and the like. Further, in the embodiment, the slider body is made of synthetic resin, but other than claim 7, it may be made of metal. Further, a ruler slider provided with the vernier scale of the second embodiment may be attached to the straightedge of the third embodiment.
