摘要:
A recording apparatus in which recording is made several times each line in a partitioning manner part after part on each recording line for which there exists picture data to be printed. The system determines whether there exists picture data to be printed on each line or not. A sub-scanning speed per line is set such that when the determination is made that one or more successive lines immediately before a recording line for which there exists picture data to be printed is or are an entire blank line or successive entire blank lines for which there exists no picture data to be printed, the sub-scanning speed for the entire blank line or successive ones of the successive entire blank lines adjacent to the recording line is selected to be substantially equal to that at the recording line. The sub-scanning speed of other entire blank line or lines for which there exists no picture data is selected to be a speed which is sufficiently higher than that for the recording line.

A thermal recording head driving system includes a device for maintaining the head at a substantially constant temperature between recording operations, the head however not being excited to an extent as could cause erroneous printing. The device is capable of preventing fluctuations in printing density owing to variations in the waste heat from the previous line recording operation.

摘要:
A heat-sensitive recording head having heat generating elements arranged on an insulating substrate and a system for preheating said substrate and controlling the heat generated during the recording operation. In one embodiment the substrate is placed in contact with a larger heat sink which is heated by a carbon-type internal resistor, a printed circuit contacting resistor, or a conventional heater. A thermal sensor detects the temperature of the heat sink and is fed to controls for controlling the overall application of heat. In another embodiment the substrate is placed in contact with a Peltier effect device which controls heat generation and absorption.

摘要:
A thermal transfer recording apparatus adapted to record an image on a recording medium by transferring a heat-transferable ink from a transfer medium to the recording medium. The apparatus has a transfer medium having on one surface a layer of a heat-transferable electroconductive ink formed on a base sheet, a recording head for heating the transfer medium in accordance with an image signal, and an electrode disposed in physical contact with the ink surface of the transfer medium so as to form a path through which electric current is allowed to flow between said electrode and said transfer medium. Therefore, the apparatus prevents any path for electricity from being formed between the transfer medium and the recording head.
