Repeatedly usable recording medium card and recording medium card processor
First Claim
1. A gaming house system comprising a plurality of gaming machines, a computer for managing the gaming machines, a plurality of recording medium cards for recording output information from the gaming machines, and a recording medium card processor being connected to the computer for managing the recording medium cards for repetitive use of the cards, characterized in thateach of said recording medium cards has:
- a card substrate made of a flexible material, a data recording portion for visually recording necessary items on a part of the card substrate, and a number-of-use-times recording portion for recording information indicating the number of card use times, equivalent to the number of times data has been recorded and erased in the data recording portion, on another part of the card substrate, and in thatsaid recording medium card processor comprises;
means for taking in the recording medium card from outside;
means for erasing contents recorded in the data recording portion of the taken-in recording medium card;
a stacker mechanism for taking in the recording medium card from said erasing means and temporarily storing the card;
means for visually recording new data sent from said computer in the data recording portion of the card taken out from said stacker mechanism;
means for reading the number of card use times from the number-of-use-times recording portion and recording a new number of card use times in the number-of-use-times recording portion; and
means for discharging the card, onto which the new data is written, to the outside.

Abstract
A recording medium card having a card substrate (20a) made of a flexible material, and a recording portion (21) for visually recording necessary items in a part of the card substrate are disclosed. The recording portion (21) has a reusable indication layer, consisting essentially of an organic compound whose crystal aggregates upon application of heat in a first temperature zone and diffuses upon application of heat in a second temperature zone different from the first temperature zone, on which the necessary items can be visually recorded and erased upon application of heat. An area (24a) is formed in a part of the card substrate, for recording information indicating the number of card use times, equivalent to the number of times data has been recorded and erased on the indication layer.
