PURPOSE:To simplify operating steps and enable to easily confirm a printing position or the like, by providing a colored transparent material with a groove or a projection as an index of the printing position. CONSTITUTION:A card holder 5 is provided thereon with an index 5a of the position in the horizontal direction and an index 5b of the position in the vertical direction, and a printing paper is provided with a blind groove part of about 0.2mm. in size to constitute an index. The material for the card holder 5 is a transparent smoked acrylic resin colored in blue, violet or the like, and a variation in the density of the smoke is generated from a difference in refractive index between the groove part and other flat surface part, so that the groove part can loom as an index. In addition, since the positional accuracy of the groove is determined by a mold, accuracy is enhanced, and since no secondary forming is required, the card holder can be manufactured inexpensively. |
