C
It is provided with a ROM (read only memory) 17 in which a program of the PU 16, a conversion table of charge / used gas amount, a conversion table of charge / used electricity amount, and the like are stored.

In the present embodiment, the specific number S and the condition number R are respectively the house number S and the house number S, as shown in FIGS.
It is composed of A, RA and card numbers SB, RB. The house numbers SA and RA are fixed numbers for each dwelling unit or building, and the card numbers SB and RB are rewritable.

Next, the operation of the card reading device 1 will be described.

First, the card A is read by the card reader 12 (step ST1). As a result, the house number SA becomes the house number R
A is compared (step ST2), and if they match, then the card number SB is compared with the card number RB (step ST3). If they match, the card number RB (number 1 in this embodiment) is deleted from the RAM 15 (step ST4), and the condition number R in the RAM 15 is updated (the updated number becomes 2). ).

Next, the CPU 16 causes the calculation circuit to add the amount G of the card A to the balance D stored in the RAM 15 (step ST5). While the calculation result is displayed on the balance charge display unit 14, the weighing device 3 is turned on, the count number of the switch 31 corresponding to the amount of gas and electricity used is converted into an amount, and this amount is subtracted by the arithmetic circuit. , The calculated value is sequentially displayed on the balance charge display unit 14 (step ST6).

In step ST2, the house number SA is the house number RA
If the card number SB does not match the card number RB in step ST3, the card A is displayed in the unusable display section 13 (step ST7), and the card A is displayed. Do not use and do not turn on the weighing device 3.
