A print head 4 is disposed below the platen 2 and facing upwardly, and as the print head 4 is moved laterally along the print lines of the platen 2, printing is performed on the print paper from the bottom side. A paper supply section 5 and a paper discharge section 6 are provided on both front and rear sides of the printing position at the bottom of the platen 2.

As shown in FIGS. 1 and 2, a pair of legs 7 are provided protruding from both sides of the lower part of the printer main body 1, and a storage space 8 is provided between the legs 7 for the continuous printing paper P1. It is being The paper supply section 5 is provided with a bin tractor 9,
The continuous printing paper P1 in the storage space 8 is fed and transferred to the printing position below the platen 2. A supply guide plate 10 is disposed in the paper supply section 5 above the bin tractor 9, and along the upper surface of the supply guide plate 10, single sheets of printing paper P2 can be inserted one by one into the printing position.

As shown in FIGS. 1 and 2, a see-through window 1 made of a transparent plate is provided on the printer main body 1 on the side of the paper discharge section 6.
A reversing guide plate 14 made of a transparent plate is mounted on the upper part of the reversing guide plate 14 by hinges 15 at both lower ends thereof so as to be rotatable about an axis parallel to the printing lines of the platen 2. A paper ejection groove 12 is formed between the upper edge of the transparent window 11 and the lower edge of the reversing guide plate 14. The paper ejection groove 12 is
It is located almost on an extension of the path of printing paper that is transported almost linearly from the paper supply section 5 through the printing position to the paper discharge section 6 side, and is formed into an elongated shape in a direction parallel to the printing lines on the platen 2. .

A stuffing force 13 is attached to the outer side of the printer body 1. Holes 1a and la are formed in the upper surface of the printer body 1 at the lower end of the transparent window 11, and the stacker 13 is held by fitting a protrusion 13a protruding from its base end into the hole 1a.

The upper surface of the stacker 13 is located almost parallel to the extension line of the above-described path of the printing paper, and holds the printed single-sheet printing paper P2 discharged from the paper discharge a12 in a stacked state in order. be able to.

The reversing guide plate 14 has a substantially square shape when viewed from the side with an upper side along the top surface of the printer body 1 and a front side along the front side of the printer body 1.

As shown by the solid line in FIG. 2, when the reversing guide plate 14 is retracted along the top and front surfaces of the printer main body 1 (hereinafter, this position is referred to as the reversing non-operating position), the reversing guide plate 14 and A paper ejection i12 is formed between the paper ejection groove 12 and the transparent window 11, and the printing paper can be ejected from the paper ejection groove 12 onto the stacker 13. Also, as shown by the chain line in Figure 2,
When the reversing guide plate 14 is rotated around the hinge 15 and opened to the printer main body 1 (hereinafter, this position is referred to as the reversing action position), the reversing guide plate 14 is placed on the extension line of the printing paper path described above. is positioned so that the printing paper discharged beyond the upper edge of the see-through window 11 forming the paper discharge groove 12 can be reversed along the inner surface of the reversal guide plate 14.

Therefore, in this printer, when printing on a plurality of pages using single-sheet printing paper P2, the reversing guide plate 14 is placed in the reversing non-operating position shown by the solid line in FIG. When the cut printing paper P2 is fed one by one along the upper surface of the board 10, printing is performed on the lower surface side of the printing paper P2 by the operation of the print head 4. and,
