BACKGROUND OF THE INVENTION
The present invention relates to an ink jet printer that performs printing on a print medium.
[0002]
[Prior art]
In an ink jet printer that can perform printing by spraying liquid ink on a sheet, images are sequentially printed on a sheet unwound from a winding unit on which a long sheet is wound. What is done is known. Therefore, in such an ink jet printer, a winding portion around which paper is wound is loaded in the printer main body.
[0003]
Here, the operator must load a winding unit around which a sheet having an appropriate width is wound in the printer body according to the print size (the size of the image to be printed). In addition, the printer body includes a pair of winding portion position regulation guides and winding portions so as to correspond to the outer sides of both ends of the winding portion in order to prevent the position in the width direction of the winding portion from deviating from an appropriate position. In some cases, a pair of paper position restriction guides for restricting the position in the width direction of the paper when being unwound and conveyed are disposed. Therefore, when replacing with a winding unit of a different size, the positions of the winding unit position regulation guide and the paper position regulation guide must be adjusted according to the width of the newly loaded winding unit.
[0004]
[Problems to be solved by the invention]
However, with respect to the printer body such as taking out the winding part used before replacement from the printer body, loading a new winding part into the printer body or adjusting the position of the winding part position regulation guide and the paper position regulation guide. Since the work is very complicated, it takes a very long time to replace the winding portion with respect to the printer main body. Accordingly, there is a problem that the efficiency of the actual print work is reduced due to an increase in indirect work related to the print work.
[0005]
Accordingly, a main object of the present invention is to provide an ink jet printer capable of improving workability at the time of replacement of a print medium.
