摘要： A method of assembling, positioning, and making connections to a thermal printhead is disclosed. A substrate is provided upon which heating elements or mesas are mounted. Leads from these heating elements are continued on the same side of the substrate as the one on which the elements are located. The leads are brought to terminal pads where connections may be made to the logic circuit which selectively energizes the heating elements to form numerals or characters on heat sensitive paper. A flat flexible cable with conductor ends exposed is held in place so that the exposed conductor ends make contact with the terminal pads of one or more of such substrates. The substrates and cable are clamped together by two metal plates. This entire assembly is mounted on a spring-loaded pivot arrangement so as to hold the heating elements against the heat sensitive paper on an advancing platen. Connections may be made between the cable conductors and the printing logic to allow the heating elements to be energized.

摘要： A thermal line printer includes a semiconductor chip for control of A .times. N heaters arrayed in N groups past which thermally sensitive paper is stepped B times in printing a line of characters in an A .times. B dot matrix. A sequential access memory stores N multibit words, one word for each character to be printed on a given line with a commutator cyclically to read words from the memory A .times. B times for each line to be printed. A ROM has an A .times. B dot matrix code therein for each available character. A time sequencer and decoder connected to the ROM is synchronized with the commutator to produce a different one bit output from the ROM each time each given word is read from memory. A set of N enable circuits leads from the ROM to N groups of heaters. A set of A enable circuits leads from the sequencer to A groups of heaters where one heater in each A group is from one of the N groups. A decoder interfaces the sequencer to the A groups of heaters and to the motor sequentially to enable the heaters in one A group for each memory cycle and in order through the A columns and B rows of the matrix.
