The printing medium is provided in a direction in which the printing medium is bent in the direction opposite to the bending direction.

[Action]

In the present invention, a plurality of discharge ports (discharge passages) having different discharge directions are provided so that the operator can selectively switch the plurality of discharge ports 3a and 3b, and as shown in FIGS. The optimum discharge passage can be selected according to the PP.

Therefore, the feeding is smooth, and it is possible to prevent paper jams and line breaks.

〔Example〕

 (A) First Embodiment FIG. 2 is an explanatory diagram of the first embodiment of the present invention.

In the figure, 1 is a platen as a feeding means, and a paper PP
2 is a printing means, which is composed of a wire dot printing head that moves in the longitudinal direction of the platen 1, and has wire dot elements arranged in a zigzag pattern on the surface facing the platen 1. .

Denoted at 3a and 3b are discharge ports (discharging passages), which are provided above the platen 1 for discharging the sheet PP, and 4a is a switching member, which forms a plurality of discharge ports 3a and 3b, and is used by the operator. It can be slid by operation.

5a is a paper guide that guides the single-cut sheet, and 5b is a feed roller that guides the single-cut sheet to the platen 1
5c is a feed guide that cooperates with and feeds a single-cut sheet around the platen 1.

6a is a pin belt tractor that engages with the feed holes on both sides of the continuous form (continuous form) to send the continuous form. 6b is a continuous form guide that guides the continuous form to be sent around the platen 1. It is a thing.

Reference numeral 7 denotes a bail roller (paper pressing roller) that presses the paper fed by the upper part of the print head 2 to the platen 1.

In this embodiment, the switching member 4a is the upper part of the platen 1,
As shown in FIGS. 2B and 2C, it is configured to be slidable by the operation of the operator.

Therefore, as shown in FIG. 2B, when the switching member 4a is moved to the left side of the drawing, the discharge port 3b is closed and the discharge port 3a is formed.

Normal paper is discharged from the platen 1 through the discharge port 3a.

On the other hand, in a paper stapler (a plurality of sheets are stacked and bound by pressing force on the sheets), by winding around the platen 1, among the layered sheets, the sheet on the platen side and the platen 1 Misalignment (this is referred to as interlayer misalignment) occurs on the paper on the opposite side.

 In order to prevent this, the paper path is made S-shaped.

That is, as shown in FIG. 1 (C), the switching member 4a is moved to the right side of the drawing to close the discharge port 3a and form the discharge port 3b.

As a result, the sheet, which has been bent along the platen 1 with the bail roller 7 as a boundary, is discharged by the discharge port 3b with a bending opposite to that of the platen 1.

For this reason, the paper path has an S shape, and it is possible to prevent interlayer deviation.

The switching member 4a may be configured to be slidable with respect to the main body frame. For example, the switching member 4a may be configured so that a part of the switching member 4a is engaged with the guide groove of the main body frame and can slide along the guide groove. Good.

(B) Second Embodiment FIG. 3 is a configuration diagram of a second embodiment of the present invention, and FIG. 4 is a third embodiment.
It is a principal part block diagram of a figure.

In the figure, the same components as those shown in FIG. 2 are indicated by the same symbols.

Reference numeral 4b denotes a front cover, which is rotatable around the rotary shaft 40, forms the first discharge port 3a, and forms the second discharge port 3b when opened.

As shown in FIG. 4, the front cover 4b is configured so as to be rotatable about the rotation shaft 40 with respect to the main body frame 8 and has an engagement protrusion 41 that engages with the protrusion 80 of the frame 8. .

Incidentally, FIG. 4 (B) is a sectional view taken along line AA of FIG. 4 (A).

In this embodiment, as shown in FIG.
Is provided at the lower part of the platen 1 so that the paper passage is formed as linear as possible and is kept away from the discharge port 3a so that noise does not leak to the outside.

 FIG. 5 is an explanatory view of the second embodiment of the present invention.

When printing normal paper, see Fig. 3 (A) and 5
The front cover 4b is closed as shown in FIG.

At this time, since the main body frame 8 is made of a molding material, the engaging projections 41 of the front cover 4b bend the molding projections 80 of the main body frame 8 to facilitate the operation. Can be set to the engaging position as shown in.

When the front cover 4b is closed, as shown in FIG. 3 (A), the second discharge port 3b is closed and only the first discharge port 3a is left, so that the paper is moved upward from the first discharge port 3a by U. Is discharged.

On the other hand, when printing thick paper such as postcards and postcards,
As shown in FIG. 5B and FIG. 5B, the front cover 4b
open.

Also at this time, the engagement protrusion 41 of the front cover 4b can bend the mold protrusion 80 of the main body frame 8 and position the engagement protrusion 41 on the mold protrusion 80.

When the front cover 4b is opened, as shown in Fig. 3 (B),
A second outlet 3b is formed.

Therefore, a strong paper such as a postcard does not follow the platen 1 but is guided from the print head 2 to the second discharge port 3b as shown in FIGS. It is discharged to F.

As a result, the curvature of the stiff paper becomes small, and it becomes possible to perform a good paper discharge operation without adversely affecting print line feed and the like.

Incidentally, in this embodiment, FIG. 3 (A) and FIG. 5 (A)
In this state, the platen 1 is located between the print head 2 and the discharge port 3a, and the noise of the print head 2 is not directly emitted as in the embodiment of FIG. Becomes extremely small.

When the front cover 4c is lowered, as shown by the solid line in FIG. 6 (B), the second outlet port 3b is blocked and the first outlet port 3c is closed.
Since there is only 3a, the paper is discharged upward U from the first discharge port 3a.

On the other hand, when printing thick paper, the front cover 4c is slid upward as shown by the alternate long and short dash line in FIG. 6 (B).

At this time, as shown in FIG. 7 (C), the front cover
The guide bar 42 of 4c extends along the guide groove 81 of the main body frame 8 and over the locking projection 81a, and the positioning is stopped on the locking projection 81a.

When the front cover 4c is slid upward, the second discharge port 3b is formed as shown by the alternate long and short dash line in FIG. 6 (B).

Therefore, the stiff paper is guided to the second discharge port 3b from the print head 2 and discharged to the left front F without passing along the platen 1.

As a result, the curvature of the stiff paper becomes small, and it becomes possible to perform a good paper discharge operation without adversely affecting print line feed and the like.

In this example, similarly to the second embodiment, since the two outlets can be selected only by configuring the front cover to be movable, it can be realized easily and inexpensively.
