2. Description of the Related Art Conventionally, in measurement work, an apparatus suitable for the measurement is usually used. Specifically, a tape measure is used when measuring the dimension of a member, and A plumb bob is used to measure the vertical state of a member, and a level gauge is used to measure the horizontal state.These tape measures, plumb bob, and level gauge are used individually as one measuring device. In particular, in a construction work, a tape measure, a plumb bob, and a leveler are used properly for the measurement work, and the members are properly assembled to proceed the construction work.

In some cases, after the members are assembled, the assembled state may be easily confirmed. At that time, the vertical state may be checked by the plumb bob, and the vertical state and the horizontal state may be checked. Although a leveler is used, the plumb bob and the leveler are formed as separate devices, so it was necessary to bring the measuring device to check the assembled state, and the work efficiency was poor.

From this, a tape measure with a level measure has been devised, which is a combination of a level measure that is often used by a worker and a level measure which is often used. I was able to get good results. However, when using the leveler, it is necessary to use it together with the tape measure case, and therefore, there is a drawback that it cannot be used in a narrow space where the tape measure case does not fit. Therefore, the tape measure with the leveler is used today. The person disappeared.

However, when confirming the above-mentioned assembled state, it is quite convenient for a worker to add a measuring device necessary for the confirmation to the tape measure, and the work efficiency is improved. It is a fact that everyone can see that it contributes to the improvement, and it has been desired to solve the drawback. Then, the present applicant has found that the above-mentioned drawbacks can be solved by using the tape measure invented by him.
