摘要： A thermal printer is capable of maintaining the heating elements thereof at a constant temperature to achieve uniform print density and to avoid abnormal heating of the heating elements. For this purpose each heating element receives a stronger driving pulse at the first printing operation in a scan line and receives a weaker driving pulse at the subsequent printing operation.

摘要： A thermal transfer printer comprising means for identifying space data present between character data in a print data string. When a space portion is detected by the space identifier, the thermal head is moved apart from the platen of the printer and the ink ribbon feed is stopped thereby preventing the waste of the ink ribbon by the space portion in a line.

摘要： A platen support structure of a thermal transfer printer, for example, has a platen holder holding a platen, a frame supporting two ends of the platen holder, and an indexing mechanism for pivotally supporting the platen holder. The platen holder is curved in the inoperative mode of the printer and is flexed linearly in the operative mode. Clear printing can be performed without irregular line feed.

摘要： A thermal transfer printer includes a thermal head having plural heat generating elements, a thermal head driver connected to a character generator for controlling the thermal head by supplying drive currents to the heat generating elements of the thermal head in response to print information, and control circuit for controlling the drive currents from the thermal head driver in response to the ambient temperature. Therefore, the thermal transfer printer is capable of constantly providing an optimum transfer density regardless of the ambient temperature, thus ensuring a satisfactory print quality.

摘要： An ink ribbon cassette has a case housing an ink ribbon inside. Holes for receiving positioning members are formed at the two ends of a front portion of the case, and an engaging member is formed at the center of a rear portion of the case. One of the positioning members also serves as an ink ribbon end detector. A printing apparatus for printing using such an ink ribbon cassette has a carriage, projections and a spring. Thus, the slackening of the ink ribbon will not occur in the printing mode.

摘要： An ink ribbon for a printing device comprises a substrate of a long thin web of a synthetic resin film having a solid ink coated on one surface thereof, the color of the substrate being the same as that of the solid ink. After the ink ribbon is used, the negative impressions left from the transfer of information to a printing sheet will be illegible.
