【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a longitudinal sectional view showing the structure of a paper roll exchange according to an embodiment of the present invention, FIG. 2 is a lateral sectional view thereof, FIG. 3 is a plan view illustrating an opening / closing device of the present invention, and FIG. FIG. 5 is a perspective view of the facsimile apparatus of the present invention.

In the figure, 100 is a main body case, 20 is a paper roll, 200 is a paper feed roller, 300 is a guide plate, 400 is a paper roll upper cover, 500 is a platen roller, 600 is a thermal head, and 110 is a door. As shown in FIG. 5, the door 110 is pivotally attached to the side surface of the main body case 100 so as to be openable and closable in the lateral direction, and the door 110 is opened so that the paper roll 20 can be inserted in the lateral direction. Below the inserted paper roll 20, there is provided a guide plate 300 whose bottom surface is inclined at a predetermined angle θ toward the paper feed roller 200. Behind the tip of the guide plate 300, the guide plate 300 comes into contact with the paper roll 20. A paper feed roller 200 that rotates in the direction of the arrow is attached.

Above the paper roll 20, a paper roll upper cover 400 that covers the paper roll 20 and guides the paper front end 21 by the front end portion 410 and the front end portion 310 of the guide plate 300 is provided. A thermal head 600 and a platen roller 500 rotatably contacting the thermal head 600 are disposed in front of the tips 310 and 410, and a guide 700 having a paper sensor 710 and a cutter 800 are disposed in front of the guide 700. It is set up.

A sensor 130 is provided on a side surface 120 of the main body case 100 on the side opposite to the door 110, which detects completion of insertion of the paper roll 20 and outputs a signal to start a motor (not shown). ing. A single motor driven by the sensor 130 rotates the paper feed roller 200 and the platen roller 500. However, the paper feed roller 200 and the platen roller 500 may be driven by different motors. When the door 110 is opened, the rod 910 moves in the direction A to pull the lever 920, and the thermal head 600 elastically urged by the spring 940 is pushed up via the cam 930. This is called a switchgear 900.

Next, a procedure for replacing the paper roll 20 will be described. When the paper roll 20 approaches the end, the sign is displayed on the edge of the paper due to coloring or the like, so the door 110 is opened and the old paper roll 20 is taken out. A new paper roll 20 is laterally inserted through the hole of the opened door 110, and when the insertion is completed, the sensor 130 detects it and a motor (not shown) is driven, so that the paper feed roller 200 and the platen roller 500 move in the arrow direction. Rotate.

When the insertion is completed, the paper roll 20 rolls in the direction of the paper feed roller 200 along the inclination angle θ of the guide plate 300, and thus contacts the paper feed roller 200 as shown by the solid line and rotates in the direction of the solid arrow. To be made. Therefore, the paper leading end 21 of the paper roll 20 passes through the gap S1 formed by the leading end 310 of the guide plate 300 and the leading end 410 of the paper roll upper cover 400, and the opened gap S2 between the thermal head 600 and the platen roller 500. It is extruded in the direction of the cutter 800. As described above, when the door 110 is opened, the lever 920 and the cam 930 move in the arrow A direction via the rod 910, and the gap S2 is created. At this time, since the platen roller 500 is rotating together with the paper feed roller 200, it easily passes through the gap S2.

However, the opening / closing device 900 may be omitted. In this case, the leading edge of the paper is pulled between the thermal head 600 and the rotating platen roller 500.

The position of the paper front end 21 that has passed between the platen roller 500 and the thermal head 600 is detected by the paper sensor 710 attached to the guide 700, so that the paper front end 21 has passed the cutter 800 at a predetermined position. Then, the cutter 800 operates to cut the paper near the leading edge 21 of the paper, and at the same time, the platen roller 500 and the paper feed roller 200 are stopped, so that the replacement of the paper roll 20 is completed.

When the door 110 is closed after the above operation is completed, when the opening / closing device 900 is provided, the rod 910 and the cam 930 shown in FIG. Since it is energized, it comes into pressure contact with the platen roller 500 and enters a recording standby state. Since the paper roll 20 is pulled by the platen roller 500 during recording after the replacement of the paper roll 20 is completed, the paper roll 20 is separated from the paper feed roller 200 as shown by the chain double-dashed line in FIG. May be rotating.
