CONTROL SYSTEM FOR INFORMATION INPUT TRANSMISSION

摘要

PURPOSE:To attain the rational and smooth jobs and furthermore to prevent crimes by adding the functions of an operator key and a job controller key respectively. CONSTITUTION:The areas 4 and 5 of a keyboard 3 are defined as the positions for insertion of a controller key for a job controller and an operator key respectively. When either one of both keys is set off, no designation (by a cursor) is displayed on an information output screen 1 for an input position after a module is read out. Thus the keyboard 3 is locked and accepts no keying of the input information. Therefore the input of information is impossible. The input information is valid only when both the operator key and the controller key are turned on.
