6 to 8 show an information communication apparatus according to an embodiment of the present invention as claimed in claims 2 and 3, and the same or similar parts as those of the embodiment shown in FIG. 1 are designated by the same reference numerals. The description is omitted here. In the embodiment shown in FIGS. 6 to 8, a curl removing member 17 is provided at a fixed position upstream of the recording head 5. Similar to the conventional curl removing member 4 (see FIG. 9), the curl removing member 17 includes an inlet-side first bent portion 17a and an outlet-side second bent portion 17b. The side is extended and the support surface 17 is extended.
The supporting surface 17c is located above the recording paper pull-out side of the recording paper box 2 that accommodates the roll-shaped recording paper 1.

At the bottom of the recording paper box 2, the recording paper pulled out from the roll-shaped recording paper is constantly curled.
On the other hand, recording paper holding means 20 is provided for lifting the roll-shaped recording paper 1 in accordance with the decrease in diameter so that the rolled recording paper 1 is contacted at an angle effective for curl removal. This recording paper holding means 2
0 is a recording paper lifting lever 23 rotatably provided around a support shaft 22 rotatably held by a support plate 21.
And a lever tension spring 24 for applying an upward turning force to the recording paper lifting lever 23. The leading end of the recording paper lifting lever 23 is formed in a shallow V shape so that the rolled recording paper 1 can be stably held. Here, as shown in FIG. 7, the length of the recording paper lifting lever 23 and the position of the support shaft 22 are set so that the roll-shaped recording paper 1 having a smaller diameter is lifted to support the curl removing member 17.

However, when the diameter of the roll-shaped recording paper 1 becomes small to some extent and the weight of the roll-shaped recording paper 1 becomes small, the lever tension spring 24 overcomes the weight of the roll-shaped recording paper 1 and lifts the recording paper lifting lever 23, as shown in FIG. As described above, the rolled recording paper 1 is attached to the support surface 1 of the curl removing member 17.
Press on 7c. For this reason, the recording paper 1a pulled out from the roll-shaped recording paper 1 is bent along the first bent portion 17a on the entrance side of the curl removing member 17 for good curl removal, and a large curl of the recording paper 1a is generated. Good removal. Further, since the roll-shaped recording paper 1 is constrained by the recording paper lifting lever 23, the support surface 17c of the curl removing member 17, etc., the position is stable and no skew occurs, and
Appropriate back tension can be applied and image quality does not deteriorate.

When the roll-shaped recording paper 1 is replaced,
The opening / closing part 29 is opened around the support shaft 28 as shown in FIG.
At this time, as the opening / closing part 29 rotates, the protrusion 30 provided on the opening / closing part 29 engages with the pin 27 of the lifting lever returning slider 25, and the lifting lever returning slider 25.
In the direction indicated by arrow A. The movement of the lifting lever returning slider 25 in the direction of arrow A is transmitted to the recording paper lifting lever 23 by the pin 26 and pushes down the recording paper lifting lever 23 to the lower position. Thus, the opening / closing part 2
When 9 is opened, the recording paper lifting lever 23 is at the lowered position regardless of the size of the rolled recording paper 1 held, so that the rolled recording paper can be easily replaced.
