摘要:
Upon executing printing by latching an input digital image signal temporarily stored in a shift register (502) by a latch circuit (501), and energizing and driving a heater (401) using a power transistor (410) using an nMOSFET on the basis of the latched image signal, a voltage converter (111) boosts a voltage representing the ON state of the latched digital signal, and applies the boosted voltage to the power transistor (410).

摘要:
A printing head, which is used for a printing apparatus for printing out the printing data externally inputted from a data processing apparatus to a recording medium, comprises printing execution means for printing out the externally inputted printing data to a recording medium; data detection means for detecting security data form the externally inputted printing data; and operation control means for controlling the printout operation of the printing execution means in a given condition when the data detection means detects security data. With the printing head thus structured, no printout is possible even when the image data is transmitted from the data processing apparatus to the printing apparatus if security data is detected from the transmitting data for printing.
