Abstract
The printer (1) includes a control unit (20) including a function reproducing multiple tones by outputting energization data that is dot control data in multiple cycles in line units to a head unit (10) including a plurality of dot generating elements disposed in a line. The control unit (20) includes: a thermal head control circuit (60) supplying the energization data of each cycle and a latch signal for the energization data of each cycle to the head unit (10); and a mask circuit (70) operable when the energization data of the current cycle is the same as the energization data of the previous cycle, to erase the current energization data and the signal for latching to be supplied to the head unit (10).
Claims10
A control apparatus that reproduces multiple tones by outputting dot control data in multiple cycles in line units to a head unit including a plurality of dot generating elements disposed in a line, comprising:
- a signal supplying unit supplying dot control data of each cycle and a signal for latching the dot control data of each cycle to the head unit;
- and
- an erase unit operable when dot control data of current cycle is same as dot control data of previous cycle, to erase at least one of the dot control data of current cycle and the signal for latching the dot control data of current cycle to be supplied from the signal supplying unit to the head unit.
A control method of an image generating apparatus including a control apparatus supplying dot control data to a head unit including a plurality of dot generating elements disposed in a line,
- wherein the control method includes reproducing multiple tones by outputting dot control data in multiple cycles in line units from the control apparatus,
- and the reproducing multiple tones comprises:
- supplying the dot control data of each cycle and a signal for latching the dot control data of each cycle to the head unit;
- and
- erasing, when dot control data of the current cycle is same as dot control data of previous cycle, at least one of the dot control data of current cycle and the signal for latching the dot control data of current cycle to be supplied to the head unit.
