<p>PURPOSE:To make possible the high-level processing of data free from restrictions to the use of an information recording medium without the provision of a power supply in the medium by arranging a crystal liquid layer between a transparent electrode substrate and a light conductor, recording information to be recorded for an operator and recording information to be recorded for machine in the form of a signal. CONSTITUTION:When a passenger passes through a wicket using a card 1, it is charged into an automatic ticket checker at a boarding station in a state that the card balance of Yen1,000 is for instance, displayed in the balance indication area 2a of a visible information display section 2. Then a voltage for deletion VHH is applied to the balance indication area 2a through contacts 16a, 16b, and an indication in this area 2a is deleted. In addition, simultaneously an image complying with information about ticket examination such as the name of a boarding station 'Tokyo', a current balance 'Yen1,000' and data when the card is used 'August 10, 1988' is exposed to light for the information indication area 2b. Then a visible image is formed in the information indication area 2b by application of an appropriate voltage VDC through the contacts 16a, 16b. At that time, information is magnetically recorded in a magnetic stripe 5 and an IC6.</p> |
