According to the third or sixth aspect of the invention, similarly to the above, the weight of the group of money which is expected to be equal to or less than the weight of the permissible maximum number of sheets or less than or equal to the permissible value of the fractional part is measured. When given to the means, the number of receipts and the amount of money for the first time are calculated in the same manner as described above, and the reference weight for the money received for the next time is calculated based on the weight received for the first time and the calculated number of sheets, Subsequently, when the next group of money is given to the weight measuring means, the number of receipts and the total amount of money are calculated in the same manner as above, and based on the total value of the received weight and the total value of the calculated number of times in the current time, The reference weight of the next time is calculated, and thereafter, the number of receipts, the total amount of money, and the reference weight are calculated in the same manner, the total amount of money to be counted is calculated, and the value of the number of acceptances or the fractional part of each time is calculated. When exceeding the volume maximum number or the fractional part tolerance, because its effect is to be notified by the notifying means, are sequentially set to a value that the reference weight is based on the measured, the measurement accuracy is improved. If the maximum allowable number of coins or the allowable fractional value for each denomination is properly set in the same manner as above for the money received at each time, the amount of money received will not be incorrect, and therefore the total amount of money It is counted without error.

Further, according to the invention of claim 4 or claim 7, the money of the group consisting of an amount which is expected to be less than or equal to the weight of the permissible maximum number of sheets or less than or equal to the fractional part permissible value is initially used as the weight measuring means. If given, the number and amount of money received at the first time are calculated in the same manner as above, and the reference weight for the money received at the next time is calculated based on the weight received at the first time and the calculated number of sheets. When the money of the group is sequentially given to the weight measuring means, the number of receipts and the total amount of money are calculated in the same manner as above, the reference weight of the next time is calculated, and the total amount of the counted money is calculated,
When the accepted amount of the coins exceeds the maximum allowable number of coins or exceeds the allowable fractional part of coins, the notification means is notified and the first maximum allowable number of coins is accepted for the first receipt. Or, when the first fractional part allowable value is exceeded, and when the second maximum allowable number of sheets or the second fractional part allowable value is exceeded for the next and subsequent times, the same shall be announced respectively. Therefore, the first allowable maximum number of sheets or the first decimal point allowable value is set based on the variation including moisture absorption, and the second allowable maximum number of sheets or the second decimal point allowable value is the variation at the time of constant moisture absorption. By setting it based on the above, the reference weight is sequentially set to a value based on the actual measurement, and the bill is corrected to a value in which the change in weight due to humidity is also considered, and the measurement accuracy is improved. .. And for the money accepted at each time, if the maximum allowable number of coins for each denomination is set appropriately as above,
There is no error in the amount of money received, and therefore these total amounts are counted without error.
