<p>PROBLEM TO BE SOLVED: To check lot informations by the release operation of a masking slip, obviate the necessity of the special processing for preventing the damage to the informations and increase the display information amount. SOLUTION: Bonding force strengthening agents 4a, 4b and 4c are provided on the sections corresponding to lot informations 2a, 2b and 2c of a base plate 3 of a lot sheet 1, and masking slips 5a, 5b and 5c are disposed on the sections of providing the bonding force strengthening agents 4a, 4b and 4c so that relative pressure-sensitive bonding agent layers 6a, 6b and 6c provided on the rear faces of the masking slips are faced to the sections of providing the pressure- sensitive bonding agent layrs, and pressure bonded together, and the bonding faces of the pressure-sensitive bonding layers 6a, 6b and 6c with the bonding force strengthening agents 4a, 4b and 4c are set to be releasable, while the lot informations 2a, 2b and 2c are set to be invisible. When the masking flaps 5a, 5b and 5c are turned over, the bonding faces of the pressure-sensitive bonding agent layers 6a, 6b and 6c with the bonding force strenthening agents 4a, 4b and 4c are released and the lot informations 2a, 2b and 2c are visulized.</p> |
