PURPOSE:To prevent omission of a part of continuous input data, by informing a CPU and other host apparatuses that an input data has been generated, in case when an input operation has been executed by an operator. CONSTITUTION:An item panel controlling part 2 which has received this signal (b) only sends out an information signal (e) for informing that input data has been generated, to a CPU and other host apparatuses through a CPU interface circuit 5, and a display instruction signal (c) to the display menas is not generated. Subsequently, when the CPU, etc. receive and confirm this information signal (e), the CPU generates the display instruction signal (c) as a confirmation signal ACK, and transmits a signal (d) to the item panel control part 2 through the CPU interface circuit 5. |
