<p>PURPOSE:To decide accurately the switching operation requested by an operator even though the intermediate position is operated between two adjacent switches, by using both a counter means and a comparison/decision means. CONSTITUTION:The information input switches Sa and Sb consist of matrix switches Sa1-Sa9 and Sb1-Sb9 respectively. When almost a middle position between symbol marks 12a and 12b is pressed, the number of pieces applied are counted among those switches Sa1-Sa9 and Sb1-Sb9 corresponding to both marks 12a and 12b respectively. Then, the number of switches applied are compared with each other between both types of switches. Thus, the operations of switches Sa is decided when the number of switches Sa applied is larger than that of the switches Sb applied. This secures the accurate decision of the switching operation requested by an operator even in case an intermediate position between two adjacent switches is operated.</p> |
