PURPOSE:To improve the reliability of a transaction processor by checking whether or not a command received from a control section is inadequate through the collation with a table to prevent in advance the execution of improper processing. CONSTITUTION:A command combination table representing whether or not the combination between the preceding command and this command transmitted from a control section 10 to a function section is provided to the function section and the function section references the said table when a command is transmitted from the control section 10 to discriminate whether or not the combination between this command and the preceding command is inadequate, and when the combination is not inadequate, the processing according to this command is attained. For example, an inadequate command combination table (area M2) is provided in a memory 22 of a coin processing section 20 and when the combination between this command the preceding command corresponds to a combination registered in the table of the area M2, it is informed to the control section 10 that this command is inadequate. |
