Patent number: 4642659Abstract: The improved image building apparatus is constructed such that recording medium, that is, recording paper, is normally introduced into the image building section with a thermal head or the like component incorporated therein while it is stretched under the effect of a certain intensity of braking force which is exerted on the recording paper from the rear side as seen in the direction of transportation thereof. This causes an occurrence of such a malfunction as skewing, loosening or the like of the recording paper to be inhibited at least in the image building section. Thus, image building can be achieved without incorrect registering, deformation or the like recognized with the printing paper on which image transference has been carried out.Type: GrantFiled: February 27, 1985Date of Patent: February 10, 1987Assignee: Kabushiki Kaisha ToshibaInventors: Masayoshi Nagashima, Tomohiko Takahashi, Naoto Higure, Kanehiro Fukuda

Patent number: 4586834Abstract: According to the present invention, a transfer medium is set to be fed. Transfer materials are set to be selectively fed in such a manner that each transfer material has a monochromatic color agent and an identification code assigned thereto, or a plurality of color agents and identification codes assigned thereto. A first feeding means feeds the transfer medium, while a second feeding means feeds the transfer material. A transfer portion transfers a color agent of the transfer material fed by the second feeding means to a transfer medium fed by the first feeding means in accordance with printing data. A detecting means detects the identification code of the transfer material. A controlling means discriminates the type of transfer material in accordance with the identification code detected by the detecting means. The controlling means changes the printing mode in accordance with this discrimination result.Type: GrantFiled: September 26, 1984Date of Patent: May 6, 1986Assignee: Kabushiki Kaisha ToshibaInventors: Takaaki Hachisuga, Tomohiko Takahashi, Koji Kagaya, Masayoshi Nagashima
