PURPOSE:To obtain a slip processor which excels in the operability, the function properties, and the responsiveness by separating a latest slip data base from a history slip data base for the reference of registration and the retrieval. CONSTITUTION:A latest slip number deciding device 1c compares the slip data received from an input/output device 6 with a latest slip data base 5a via a data base input/output controller 1b with a command of a slip data register 1a. Thus it is decided whether the slip data is equivalent to the latest information or not. Then the device 1c informs the register 1a of the decided result. The register 1a registers the slip data into the base 5a via the controller 1b if the received result is equivalent to the latest information. If the decided result of the device 1c is decided as the old information, the register 1a compares the contents of a history slip data base 5b corresponding to the old slip data with all contents of the old slip data through a slip comparator means 1e and via the controller 1b. If no coincidence is obtained from the comparison, the slip data are registered into the base 5a via the controller 1b. |
