PURPOSE:To realize the credit transactions through the slip control and at the same time to simplify the operation of keys, by specifying the credit transactions by means of a credit transaction specifying means and supplying the data on the goods. CONSTITUTION:The credit key is operated on a keyboard 10 to specify a credit transaction. Thus a CPU30 discriminates whether or not an FP flag 46 showing the credit transaction and an FD flag 47 showing the set request of a slip are set. If these flags are not set, the setting of an FN flag is discriminated. If the FN flag is not set, the data stored in a WN work register 42 is transferred to a work register 43 as a data on the preceding credit loan balance. Then the FN flag 45 is reset, and the FP flag 46 and the FD flag 47 are set. And a display showing the request for a slip is lit up. |
