Abstract

An improved image building apparatus of the type including a platen roller and a recording head in which a recuired image is built on printing medium by transfering coloring agent on ink donor medium onto printing medium with the aid of the recording head which is activated in response to image information while ink donor medium and printing medium are interposed between the platen roller and the recording head. To construct the apparatus in smaller dimensions the platen roller is disposed in the area located between a pair of cores in the cassette in which ink donor medium is spanned therebetween. Arrangement is made such that the platen roller is displaced together with the cassette as the latter is fitted to or removed from the housing of the apparatus. The housing includes a pair of casette supporting members which are removably inserted into openings of the cores in the cassette. Each of cassette supporting members has a hollow space in which a plurality of dry batteries are accommodated as electric power source for the apparatus.
