摘要： A thermal head apparatus includes a heat generation driving integrated circuit and a current detecting integrated circuit. The heat generation driving integrated circuit is constituted by a plurality of first switching elements respectively connected in series with current detecting resistors, a first shift register for serially inputting print input data for heating heat generation elements, a first latch circuit for latching the print input data input to the first shift register at a predetermined timing, and a first output gate circuit for selectively controlling energization of the first switching elements on the basis of the print input data latched by the first latch circuit. The current detecting integrated circuit is constituted by a plurality of second switching elements respectively connected to connection points between the heat generation elements and the current detecting resistors, a second shift register, a second latch circuit, and a second output gate circuit for selectively controlling energization of the second switching elements on the basis of the data latched by the second latch circuit, the current detecting integrated circuit outputting, as serial data, current detection data which energizes the second switching elements.

摘要： A thermal printer head comprises an array of heating elements (1-1∼1-N) mounted on an insulating base member (20). Each of the heating elements is connected to a common voltage source (V) and has a temperature dependent electrical resistance. Electrically resistive elements (2-1∼2-N) are respectively connected in series with the heating elements to form a plurality of series circuits Current supply circuits (3-1∼3-N, 4-1∼4-N, 5, 6, 7-1∼7-N, 14) are provided corresponding respectively to the resistive elements for selectively supplying a current to the series circuits in response to a sequence of print signals. A control circuit (8-11, 14) makes a determination whether a voltage developed across each resistive element is higher or lower than a prescribed threshold value and causes one of the current supply circuits corresponding to the resistive element to control the current depending on the determination.
