The automatic paper feeder screw 344 is passed through the mounting hole 341, and the roll paper holder mounting portion 230 is inserted into the gap 342 so that the end of the notch 231 is supported by the automatic paper feeder screw 344. In this state, when the automatic paper feeder screw 344 is screwed into the automatic paper feeder screw hole 343, the automatic paper feeder 200 is fixed to the roll paper holder main body 310a.
[0016]
FIG. 6 is a side sectional view showing a state in which the roll paper 10 is set in the thermal line printer system 500 according to the embodiment of the present invention. When the roll paper 10 is used as the printing paper, the leading end of the roll paper 10 is transferred between a platen roller 150 provided in the housing 110 of the thermal line printer 100 shown in FIG. 6 and a thermal printer head 151 (not shown). Pull it out to the contact. The thermal printer head 151 is in rolling contact with the platen roller 150 with a predetermined pressure contact force. When print information is transmitted from a device such as a personal computer, the thermal printer head 151 generates heat based on the print information, and the platen roller 150 is driven to rotate so that a print image is formed on the roll paper 10. The roll paper 10 is conveyed toward the paper discharge outlet 103.
[0017]
When the automatic paper feeder 200 is attached to the roll paper holder main body 310a, the automatic paper feeder 200 has the roll paper 10 on the bottom surface of the housing 210 of the automatic paper feeder 200 and the top surface of the housing 110 of the thermal line printer 100. It is attached so as to have a gap that can be smoothly conveyed. Therefore, the roll paper 10 can be used as the printing paper even when the automatic paper feeder 200 is attached to the roll paper holder main body 310a.
[0018]
3 and 4 are perspective views showing a state in which cut sheets are set in the thermal line printer system 500 according to the embodiment of the present invention. As described above, the cover member 320a is swingably supported by the roll paper holder main body 310a. As shown in FIG. 2, the boss 321 connecting the cover member 320a and the roll paper holder main body portion 310a is disposed on the rear side of the rear end edge 353 of the cover member 320a, and from the back surface 354 of the roll paper holder main body portion 310a. It is arranged on the rear side. Therefore, in a state where the cover member 320a is in the open position, the roll paper holder 300 has a predetermined gap 350 between the rear end edge 353 of the cover member 320a and the back surface 354 of the roll paper holder main body 310a.
[0019]
Further, the roll paper holder main body part 310a includes cut paper guides 352 for guiding paper to both side surfaces inside the roll paper holder main body part 310a. Cut paper guide bosses 355 are provided on both side surfaces inside the roll paper holder main body 310a. The cut paper guide 352 is swingably supported by the roll paper holder main body 310a via a cut paper guide boss 355. When the cut paper 20 is used, the user sets the cut paper guide 352 at the undulation position as shown in FIG. 3, and when the cut paper 20 is not used, the user places the cut paper guide 352 as shown in FIG. Can be stored in the lying position.
[0020]
FIG. 5 is a side sectional view showing a state in which the cut sheet 20 is set in the thermal line printer system 500 according to the embodiment of the present invention. When the cut paper 20 is used as the printing paper, one end of the cut paper 20 is inserted into a predetermined gap 350 as shown in FIG. 5, and both sides of the cut paper are guided by the cut paper guide 352 set at the undulation position. The other end is inserted into the insertion port 202 of the automatic paper feeder 200 so as to be brought into contact with a feed roller 250 provided inside the housing 210 of the automatic paper feeder 200. At this time, the cut sheet 20 is along the inner surface 351 of the cover member 320a by the elastic force of the cut sheet 20.
[0021]
In the thermal line printer system 500 according to the embodiment of the present invention, the predetermined gap 350, the inner surface 351 of the cover member 320a, and the cut sheet guide 352 have the same functions as the sheet tray. Therefore, the thermal line printer system 500 does not need to be provided with a paper tray dedicated to cut paper. The feed roller 250 is driven to rotate by detection of a paper sensor (not shown) provided in the thermal line printer 100 and the automatic paper feeder 200, and the cut paper 20 is conveyed toward the paper discharge port 203 of the automatic paper feeder 200. And set in the thermal line printer 100. When print information is transmitted from a device such as a personal computer, the thermal printer head 151 generates heat based on the print information, and the platen roller 150 is driven to rotate so that a print image is formed on the roll paper 20. The roll paper 20 is conveyed toward the paper discharge outlet 203.
[0022]
【The invention's effect】
As described above, according to the present invention, in a printer apparatus system that can use a plurality of types of paper, the components are shared without providing a dedicated conveyance path, paper holder, paper tray, or the like for each paper. Since the configuration allows a plurality of types of paper to be used, the configuration can be simplified, the apparatus can be downsized, and the cost can be reduced.
