Abstract: An image reading device has a movable platen glass that is rotatably supported, that is substantially a prism having a plurality of read faces, and that is constructed so that rotation of the platen glass can switchably place one of the read faces in the read position. Therefore, even if the platen glass becomes stained, the image reading device makes it possible to start or continue reading document images without requiring labor and time for cleaning the platen glass.

Abstract: Print is made on a recording paper by running an ink carriage along the supporting axis in a reciprocating motion. The ink carriage includes ink heads respectively provided with a front ink nozzle and a back ink nozzle facing their respective directions, so that print is made simultaneously at two portions on the recording paper along the transportation direction in which the recording paper is transported through a single transportation path one by one. Consequently, there can be provided an ink jet printer which can improve printing efficiency by increasing a printing rate and printing resolution, and realizing printing of an overstrike character, simultaneous printing of mixed information, double-side printing, etc.

Abstract: In a case of printing documents having a plurality of pages (documents number c) on output sheets so as not to exceed a limited output sheets number a, the limited output sheets number a and an output copies number b are set (S1 and S2), and the documents number c is confirmed in reading the documents (S4). When the limited output sheets number a, the output copies number b, and the documents number c are recognized, a print document pages number d which is a number of original images that should be printed on each output sheet is set in accordance with the foregoing values (S5). When the print document pages number d is set, an output mode which allows the documents to be printed in accordance with the print document pages number d is set (S6), so that a printing operation is carried out (S7). Further, in S1, each of allowable amounts of sheets stored in (i) sheet feeding means, (ii) delivery means, and (iii) post-processing means may be recognized as the limited output sheets number a.
