<p>PURPOSE:To prevent a malfunction of a card reader from occurring in reading, by recording magnetic information onto an information sheet, by putting the information sheet into a tube, and by pressing the information sheet and tube so that they are integrated, thereby eliminating a recess and a projection which are made on the surface of the tube. CONSTITUTION:Magnetic information 2 is recorded on one side of an information sheet 10. Then, the information sheet 10 is put into a tube 11. In this case, for example, the information sheet 10 is inserted from the upper end of the tube 11 while the tube 11 is held in an upright position, because the information sheet 10 is thin and easily curved. Thereafter the tube 11 with the information sheet 10 inserted in it is flattened by being pressed from the front and back of the sheet 10. Consequently the information card 10 is fixed in the flattened tube 1. Therefore, the magnetic information 2 recorded on the information sheet 10 is prevented from being rubbed off.</p> |
