Is arranged so as to contact the conveying means.

(Operation) According to the present invention, since the CSF is arranged in the horizontal inserter printer as described above, when the CSF is mounted on the table, the internal drive source of the printer and the driven portion of the CSF engage with each other to move the hopper roller. Since the sheets are driven and rotated, the single-cut sheets are conveyed one by one to the printing unit, and after printing, the single-cut sheets are conveyed through the conveyance path and discharged outside the housing. Since a stacker as a stacking unit is arranged in the vicinity of this, the single-cut sheets are sequentially stacked in this stacker.

The CSF is arranged above the table with a gap that allows the print medium inserted from the table to pass through to the conveying means, and the feeding portion of the CSF is arranged so that the leading end of the print medium fed from the feeding portion contacts the conveying path means. Since it is placed on the table, the single-cut sheet manually inserted on the table is CSF
It is transported along the same route as the single sheets fed from, printed, and accumulated in the same stacker.

That is, according to the horizontal inserter printer of the present invention, a single sheet can be printed on the same route by manual feeding or an automatic paper feeding device. Therefore, since the structure is simplified and downsized, all the above problems can be solved.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory view showing the basic concept of the present invention, and FIG. 2 shows a perspective view showing one embodiment thereof, showing a state before the access cover is opened and the CSF is inserted into or removed from the printer. ing. In both figures, 31 is a horizontal inserter printer housing, 31a is a table in front of the housing 31, 32 is a CSF mounted on the table 31a with a gap through which a print medium can pass, and 32a is its Single vote 32b by rotation
, A platen, 34 is a print head, 35 is a paper transport roller arranged before and after the printing unit composed of the platen 33 and the print head 34, and 36 is a stack of sheets discharged outside the housing 31. It is a stacker.

The operation of the horizontal inserter printer having the above configuration will be described below.
