    Abstract: Provided is a recording apparatus which includes a recording portion which performs recording on a medium, a transport path which extends to the recording portion, a feeding mechanism which sends the medium to the transport path, a manual feeding path which meets the transport path in such a manner that an extending direction of the manual feeding path changes to intersect the transport path and, a guide portion which is disposed in a meeting portion between the transport path and the manual feeding path. When the medium is sent back by the feeding mechanism, the guide portion does not move and, when the medium is inserted into the manual feeding path, the guide portion moves in a direction in which the guide portion is broadened.

  • Patent number: 8925918
    Abstract: A conveying apparatus has a first conveying roller pair; a second conveying roller pair; a first conveying path through which a sheet is conveyed in such a manner that the first conveying roller pair is placed downstream of the second conveying roller pair; and a second conveying path through which the sheet is conveyed in such a manner that the first conveying roller pair is placed upstream of the second conveying roller path. A circumferential velocity of at least one of the first conveying roller pair and the second conveying roller pair is switched so as to meet conditions, i.e., |Va|>|Vb| when the sheet is conveyed through the first conveying path and |Va|?|Vb| when the sheet is conveyed through the second conveying path. Here, |Va| is an absolute value of the circumferential velocity of the first conveying roller pair, and |Vb| is an absolute value of the circumferential velocity of the second conveying roller pair.

    Abstract: A printing apparatus or printing system that uses multiple print engines to form an image on a substrate. The printing apparatus or printing system may be a surface printing system or a reverse printing system. Each of the multiple print engines has at least one color station. The color stations are arranged in the print engines and between the multiple print engines based on whether the printing system is a surface printing system or a reverse printing system to control the order in which colorant is formed on a substrate. Multiple print engines allow for, among other things, a greater color gamut and therefore assists in expansion of the standard color gamut.
