PURPOSE:To prevent warp of a record, by providing a detecting part on a part where label paper is punched, in the proximity of the center hole, in the specified directon by making a fiber direction of the label paper its reference. CONSTITUTION:A label of a 17cm doughnut disk is punched after the inside of a dotted line 1 has been molded. In this part, a direction indicating hole 3 for discriminating a fiber direction (marked with an arrow) of label paper is made in the proximity of a center hole 2 of the label. Subsequently, the label paper is stuck to a record by conforming its fiber direction. In order to prevent mixture of a label for both A and B faces, for instance, when it is decided in advance that one piece (hole 3) and two pieces (holes 3, 3') are made on the label for the face A and that for the face B, respectively, the label can be discriminated easily, is not mixed easily, and even if it is mixed, it is selected easily. |
