DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a wound scale. Specifically, the present invention relates to a method for fixing a measurement start point at the tip of a scale when performing measurement using a wound scale.

[0002]

2. Description of the Related Art FIG. 6 is a schematic perspective view of a conventional winding type scale D. The wound-type scale D has a long scale portion 20 made of metal wound and accommodated in, for example, a scale body 10 made of plastic, and the scale portion 20 is inserted into a drawing hole 11 of the scale body 10. And can be wound and stored in the scale body 10. Although not shown, scales at regular intervals are set on the upper surface of the scale section 20, and a claw-shaped section 30 is provided at the tip of the scale section 20.

The claw-shaped portion 30 is made of a metal plate, and a bent portion 32 having a rounded edge is formed at the tip of an attachment portion 31 attached to the scale portion 20. A substantially elliptical mounting hole 33 is provided in the mounting portion 31.
Is opened with its major axis direction coinciding with the length direction of the scale portion 20.
At 4, the pawl 30 is movably mounted. The size of the mounting hole 33 is designed such that the claw-shaped portion 30 mounted on the scale portion 20 can be freely moved by the same amount as the thickness of the bent portion 32. Therefore, the claw-shaped portion 30 can move in the length direction of the scale portion 20 by substantially the same amount as the thickness of the bent portion 32. As a result, when measuring the inner method of the device under test, the front surface of the bent portion 32 is pressed against the inner surface of the device under test, whereby the scale portion 20 is pushed forward by the thickness of the bent portion 32. The internal method can be measured accurately. Also, when measuring the outer dimensions, the scale portion 20 is pulled backward by the thickness of the bent portion 32 by attracting the inner surface of the bent portion 32 to the outer surface of the measured object,
Outer dimensions can be measured accurately.

The bent portion 32 is designed to have a length that slightly protrudes from the lower surface of the scale body 10 when the scale portion 20 is stored in the scale body 10. Is not in the way and is easily pulled out.

However, when measuring a long object using such a conventional roll-type scale D, there are the following problems. That is, in a construction site such as a house, there is a case where a length such as a pillar or a steel frame having a length of several meters is measured. In particular, when cutting to a predetermined length, the outer dimension is measured, but in this case, it is necessary to hook the inner surface of the bent portion 32 to the end face of the column or the steel frame. At this time, if the object is a short object, the scale part 2 is kept while the inner surface of the bent part 32 is hooked on the short surface.
The length (height) of the bent portion 32 is designed to be a length slightly protruding from the lower surface of the scale body 10 as described above. Therefore, as the length of the object becomes longer, it becomes more difficult to pull out the scale portion 20 with the bent portion 32 hooked on the object to be measured. In other words, the bent portion 32 comes off the end face of the object to be measured during the measurement, so that it is impossible to measure the size alone, and it is necessary for the assistant to hold the claw-shaped portion 30 and the like.

[0006] Even when the claw-shaped portion 30 is held, there is another problem that the longer the length becomes, the more the scale portion 20 is lifted up on the way, making accurate measurement difficult.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the conventional example, and has as its object to provide a roll-type scale that can easily measure a long object by one person.
