RECORDING HEAD SUBSTRATE, RECORDING HEAD, RECORDING HEAD CARTRIDGE AND ITS RECORDER

摘要

PURPOSE: To eliminate erroneous operation by reducing the difference of delay time between a data signal and a clock signal incident to lowering of the voltage of a logic power supply. CONSTITUTION: The recording head substrate for inputting a data signal (DATA) in synchronism with a clock signal (CLK) comprises an input terminal 105 for inputting the clock signal and the data signal, a register 104 for receiving the data signal in synchronism with the clock signal inputted from the input terminal 105 and holding the data signal, and a section 910 provided between the input terminal 105 and the register 104 and regulating the delay time of at least one of the clock signal or the data signal.
