PURPOSE:To prevent stored data such as sale information from being lost by leaving an IC memory circuit printed board and mounting other main control circuits on the printed board when a main control circuit printed board is replaced in maintenance. CONSTITUTION:The IC memory circuit printed board 3 is fitted to the main control circuit printed board 1 by a connector 2, which stores the sale information on the IC memory circuit printed board 3 through the connector 2. When the main control circuit printed board 1 is troubled and replaced, a person in charge of maintenance detaches the connector to separate the IC memory circuit printed board 3. Then, a battery 4 is connected to the IC memory circuit printed board 3, so the stored contents of the IC memory circuit are never lost. |
