Abstract
PURPOSE: To secure application of the display/print-type LSI to the display-type, print-type and display/print-type electronic desk computers each, by supplying the signal from outside to decide whether the printer is connected at the periphery to the above mentioned LSI.
CONSTITUTION: Printer FF20 is always reset when switch 3 is set under the state of no connection of the printer along with no connection of printer 4 and hammer driver 5. Thus all processes are given for no-printing to be applied as a display-type computer. While switch 3 is set under the state with connection of the printer along with connection of printer 4 and driver 5, FF20 is always set to carry out the printing process to be used as a display/print-type computer. In that case, if display unit 2 is not connected, FF20 can be used as a print-type computer. In the case of the display/print-type computer, the printing can be eliminated at all by changing contact state of switch 3.
