Abstract
PURPOSE: To make malfunctionless shift switching operation possible by information a main unit side (CPU, etc.) of the depression of a shift key by a shift signal and then by performing the shift switching operation by a sent-back operation confirmation signal.
CONSTITUTION: With the shift key on keyboard 1 depressed, a generated data signal is coded by code generating circuit 2 and sent out to a shift signal to circuit 3 at the main-unit reception side and also to shift circuit 4 at the same time. Circuit 3 checks this shift signal and then sends a signal to transmitter circuit 5 at the main unit side, thereby allowing circuit 5 to send an operation confirmation signal to circuit 4. Circuit 4 sends a signal to circuit 2 for the shift switching operation and also sends the signal to display unit at the same time, thereby displaying a change into the fixed shift mode.
