REFERENCE DEVICE FOR TATAMI MAT DIMENSIONING AND TATAMI MAT DIMENSIONING METHOD

摘要

PROBLEM TO BE SOLVED: To perform the dimensioning operation of a tatami mat without piercing a shank needle for marking when the operation is performed by using a tatami mat dimensioning device which irradiates a laser beam in all directions, to perform the operation easily visibly and surely and to align three sides simply and quickly.;SOLUTION: In the reference device 1 for tatami mat dimensioning, rise faces 3, 26a are formed in upper parts of grounding parts 2, 25 which are grounded on a tatami mat dimensioning face, reference lines 4, 28 which are aligned with dimensioning positions are formed on the rise faces 3, 26a, and the reference lines 4, 28 are formed so as to shine by the irradiated laser beam.;COPYRIGHT: (C)2001,JPO
