Problems solved by technology

[0009] If the web is stretched excessively in this way, problems such as the following may arise: In an inkjet printer capable of printing on a web, when the web is rolled up with the printing side up, if the web is rolled up like the above If excessive flattening is performed as described above, the end of the web may become entangled on the paper transport path or come into contact with the inkjet recording head (recording head wear), thereby failing to perform a correct print job or providing proper printing. quality

[0089] A first embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a schematic sectional side view of an inkjet printer (abbreviated as printer) 1 usable with cut sheets and roll papers, which is equipped with a roll paper curl correcting apparatus according to a first embodiment of the present invention.

[0090] The printer 1 includes a printer main unit 3 , a paper feeder 5 located behind the printer main unit 3 , and a paper discharge portion 7 formed in front of the printer main unit 3 .

[0091] The sheet feeder 5 is provided with a hopper (feed tray) 9 in which many single sheets are piled up on each other, and a sheet feed roller 13 for feeding one sheet at a time is located just downstream of the hopper 9 . On the other hand, the roll paper supply unit 11 for holding the paper roll R of the roll paper P is located behind the hopper 9 and forms a passage in which the roll paper P fed from the paper roll R passes through...

Abstract

A roll paper curl correction device has a clamp roller for clamping and transporting roll paper, and a guide member comprising a guide face being positioned in the downstream proximity of the clamp roller and formed so that the roll paper is curved to an opposite side of a curl tendency of the roll paper for coming in contact with the non-print side of the paper roll. The guide face can be a curve face formed so as to curve to the opposite side of the curl tendency of the roll paper.

Description

technical field [0001] The present invention relates to an apparatus for correcting web curl and a recording apparatus including the apparatus. Background technique [0002] In recording devices typified by facsimile machines, printers, etc., it is necessary to use roll paper on which long recording (printing) can be performed. In recent years, a consumer-oriented printer for photographic quality has been developed that is capable of printing at silver halide levels from web paper. [0003] On the other hand, roll paper has a characteristic different from general cut paper, that is, it has a property of remaining curled after being unrolled because the roll paper is rolled up like a roll. Thus, there is a disadvantage in handling the web after printing. That is, if the roll paper is curled, the possibility of paper jams during printing increases, and the prints cut to a predetermined length in cut sheets are coiled and difficult to press neatly. flat. [0004] In order t...
