  • the roll paper 1 is nipped and carried by the first drive roller 20 and the first pinch roller 21 , and is then nipped and carried by the second drive roller 23 and the second pinch roller 24 . Due to the carriage, as illustrated in FIG. 7 , a front end portion of the following roll paper 1 pushes up and passes through the flapper 25 and then passes through a gap between the third and fourth drive rollers 29 and 30 and the preceding sheet P 1 .
  • the third and fourth pinch rollers 33 and 34 are separated from the third and fourth drive rollers 29 and 30 by a tensile force of the tension spring.
  • the cam drive motor 55 is operated to operate the cam 54 and the plate spring (not shown) is bent, so that the third and fourth pinch rollers 33 and 34 come in contact with the third and fourth drive rollers 29 and 30 by a weak pinch force via the preceding sheet 21 and the following roll paper 1 , while the carrying of the roll paper 1 is continued.
  • the cutter 17 is operated to cut the sheet by the same length as that of the preceding sheet 21 so as to be carried as a sheet 22 .
  • the stopper 39 is in the stopped state as is, and as illustrated in FIG. 8 , a front end portion of the sheet P 2 comes in contact with the stopper 39 and stops. As the sheet P 2 stops, rear ends of the preceding sheet P 1 and the following sheet P 2 are justified. When there are three or more sheets, similarly, the carriage is repeated to print and store a predetermined number of sheets.
  • the third drive motor 53 is operated from the state illustrated in FIG. 8 to open the shutter 56 .
  • the cam drive motor 55 is operated to rotate the cam 54 so that a degree of bend of the plate spring (not shown) increases to allow the third and fourth pinch rollers 33 and 34 to come in pressing contact with the third and fourth drive rollers 29 and 30 so as to apply a strong pinch force.
  • the second drive roller 23 is rotated in the normal direction and the third and fourth drive rollers 29 and 30 are rotated in the reverse direction. Accordingly, the sheets P 1 and P 2 on the first and second arc carrying routes 26 and 27 are carried toward the discharge opening 44 as illustrated in FIG. 9 .
  • the third drive motor 53 is operated and the fifth pinch roller 43 comes in pressing contact with the second drive roller 23 .
  • the sheets 21 and 22 are nipped and carried by the pressing contact and stopped at a time point when the front end portions thereof in the carrying direction are carried out by a predetermined length from the discharging opening 44 .
  • the sheets 21 and 22 of which the front end sides are discharged through the discharge opening 44 are received by a user.
  • the third and fourth pinch rollers 33 and 34 are separated from the third and fourth drive rollers 29 and 30 to be in an opened state, so that only the fifth pinch roller 43 is in a pinched state.
  • the sheets 21 and 22 carried out from the discharge opening 44 by a predetermined length are detected by the discharge detection sensor 58 .
  • the detected state continues for a predetermined time or longer, it is determined that the user does not take out the sheets 21 and P 2 from the discharge opening 44 , so that the sheets 21 and 22 are recovered.
  • the third and fourth pinch rollers 33 and 34 come in pressing contact with the third and fourth drive rollers 29 and 30 so as to apply strong pinch forces, and as illustrated in FIG. 10 , the sheets P 1 and P 2 are additionally carried for a predetermined distance in a discharge direction and are stopped when their lower ends pass through the flapper 36 . Thereafter, by the operation of the flapper drive motor 37 , the flapper 36 is rotated in the left direction about the spindle 36 a so as to switch the carrying route to the recovery carrying path 46 . The second drive roller 23 is rotated in the reverse direction from this state, and the third and fourth drive rollers 29 and 30 and the recovery drive roller 48 are rotated in the normal direction. Accordingly, as illustrated in FIG. 11 , the sheets P 1 and P 2 are carried downwards and sent to the recovery carrying path 46 , and as illustrated in FIG. 12 , are sent to the recovery unit 50 so as to be recovered.
  • first and second arc carrying routes 26 and 27 constituting the arc carrying route 28 are arranged in the vertical direction on upper and lower sides of a line component 66 extending along a sheet carrying surface 65 in the first printing unit 5 a as illustrated in FIG. 1 .
  • an upper side from the line component 66 is used as an arrangement space of the first arc carrying route 26 and a lower side from the line component 66 is used as an arrangement space of the second arc carrying route 27 , so that the first and second arc carrying routes 26 and 27 can be arranged while being gently curved in the wide spaces.
  • the sheet is carried in the first and second arc carrying routes 26 and 27 while being gently curved, so that the sheets can be properly carried and stored without jamming.
  • both the first and second arc carrying routes 26 and 27 are arranged in, for example, the space lower than the line component 66 , the first and second arc carrying routes 26 and 27 have to be curved in the narrow space.
  • the first and second arc carrying routes 26 and 27 are significantly curved, and the sheets are also significantly curved and carried, so that proper carriage cannot be expected.
  • the storage unit is configured by the curved carrying route 28 including the first and second arc carrying routes 26 and 27 , and the sheets P 1 and P 2 are stored in the curved state, so that the vertical height of the sheet storage unit can be reduced, resulting in a compact size.
  • first and second arc carrying routes 26 and 27 are arranged on the upper and lower sides of the line component 66 extending along the sheet carrying surface 65 in the first printing unit 5 a , it is possible to arrange the first and second arc carrying routes 26 and 27 while being gently curved in the wide space. Therefore, the sheets can be carried in the gently curved state, so that it is possible to properly carry the sheets without jamming.
