PURPOSE:To obtain an efficient input device and to make the line use into necessary minimum by adopting a bar code system as an input means and executing the on-line transmitting and receiving and the off-line transmitting and receiving in accordance with the urgency of a transmitting receiving telegram concerning the line use. CONSTITUTION:By tracing mechanically a bar code for input printed at a bar code printed matter 22 with a bar code reader 5 by a user, an efficient input is executed. Concerning the data processing of internal buffers 11,12 and 13, for example, an on-line processing is executed for the data such as the reservation number of the user at the time of issuing a reservation ticket and an off- line processing is executed for the data which can be repeated for a constant period such as the printing are not changed for a long time such as a printing format, an action is executed so as to optimize such as making unnecessary the line processing. Thus, the transmitting receiving telegram can be shortened and the machine use can be efficiently executed. |
