    摘要： A drive device for selectively driving, through a plurality of recording cycles, a plurality of N heating elements (50) in the recording means, such as a thermal print head, of a recording apparatus, wherein the energizing period for each heating element in each cycle is divided into at least M successive subperiods (TW0, TW1; TW2, TW3, TW4), comprises first to M-th storage means (11, 12) for storing first to M-th sets of recording data each set including data for said plurality of heating elements, said first to M-th sets of recording data corresponding to a current cycle and the (M-1) preceding cycles, timing means (21-25, 31-34) for defining said at least M subperiods, first means (13-15) for generating, depending on the respective recording data in each of the sets of recording data corresponding to the current cycle and the first to (M-1 )-th preceding cycles, a signal for energizing a respective heating element during a first one of said subperiods, at least second means (17, 16) for generating, depending on the respective recording data in the set of recording data corresponding to the current cycle, a signal for energizing a respective heating element during an M-th subperiod, and writing means (26, 35, 36) for selectively writing a new set of recording data for the next cycle into the storage means previously holding the set of recording data corresponding to the (M-1 )-th preceding cycle, wherein said writing means is responsive to said timing means for performing the writing between the end of said first subperiod and the end of the current cycle, and the time sequential order of said first to M-th subperiods is selected such that the time interval between the end of the first subperiod and the end of the current cycle is sufficient for writing said new set of recording data. If M > 2, third means are provided for generating, depending on the respective recording data in predetermined combinations of said sets of recording data excluding the set corresponding to the (M-1 )-th preceding cycle, respective signals for energizing a respective heating element during each of the second to (M-1 )-th subperiods.

    摘要： In a thermal printer for thermo-sensitive recording, a plurality of heating resistors (2) are electrically divided into N units each having M heating resistors, and N driver circuits (3), N latch circuits (4) and N shift registers (5) which are interconnected in tandem are respectively provided in association with the N units of M heating resistors. Dot data signals and associated hysteresis correction signals are collectively applied to the shift registers so that a pulse for print data and a pulse for hysteresis correction data can be applied continuously for printing.

    摘要： A fixed head thermal printer has a plurality of printing elements defining a line of print. Power is supplied to blocks of elements sequentially with a number of blocks receiving power simultaneously, that number being determined in accordance with the number of dots to be printed. The width of the paper is detected and elements not adjacent the paper are prevented from operating. In one embodiment, slack in a loop of paper from a roll is detected to control the driving soeed of the roll.

    摘要： A plurality of driving ICs (7) are mounted on a thermal print head (1) equipped with a predetermined number of heating dots (3). The number of output bits of each driving IC (7) is a divisor of 1/4 of the number of heating dots (3) and is set to a multiple of 8 not smaller than 48. Therefore, a plurality of driving ICs (7) can be grouped into two or four groups, and each group can be subjected to time division control. When the number of output bits of each driving IC (7) is set to a common divisor of 1/4 and 1/3 of the number of heating dots (3), the thermal print head (1) can be controlled by 3-division control in addition to 2-division control and 4-division control. More concretely, the number of output bits of each driving IC (7) is preferably set to 72, 144 or 216, particularly preferably to 144.
