Next, print control of the printing apparatus 1 will be described. The print data sent from the user's portable information terminal device 100 (Fig. 13) is transmitted via the USB connector 31 or IrDA light emitting / receiving element 34, respectively, to the USBI / ¥ drive circuit 32 or Input to CPU 30 via Ir DA modulator / demodulator 33 It is. The CPU 30 processes the print data while storing the data in the SRAM 43 according to the processing procedure stored in the ROM 44, and based on the processing content, the feed motor drive circuit 40 and the thermal head control circuit. 4 Perform the control of 2. The feed motor drive circuit 40 drives the step motor 39 based on the control of the CPU 30, and rotationally drives the sheet feed roller 20 and the platen roller 22 mechanically connected to the step motor 39.

When the case cover 4 is closed, the urging force of the spring 4 g of the case cover 4 is applied to the cut paper S stacked via the paper presser 4 d and the auxiliary sheet 6 c, so that the cut paper S is cut. Is pressed against the feed roller 20. When the paper feed roller 20 rotates in this state, the lowermost cut paper S is separated from the remaining cut paper S and transported by the frictional force with the paper feed roller 20. At this time, a plurality of sheets of cut paper S may be multi-fed due to the influence of mutual frictional force, but when the conveyed cut paper S collides with the inclined surface 21a, the cut paper S is cut. Due to the frictional force between the front end surface in the conveying direction and the inclined surface 21a, the multiply fed cut paper S is separated into single leaves.

The thus separated web S is guided by the inclined surface 21 a and collides with the guide plate 27. The guide plate 27 transports the cut paper S in the horizontal direction and supplies it between the platen roller 22 and the paper guide 23. The paper S is generated between the platen roller 22 and the platen roller 22 with the rotation of the platen roller 22 while being pressed by the paper guide 23 so as to adhere to the platen roller 22. The outer peripheral surface of the platen roller 22 is reversed in a horizontal U-shape by the frictional force, and is conveyed to a predetermined printing position. It is pressed against the top of the platen roller 2 2 by the biasing force of Unibane 2 6 by head 2 5 the thermal abuts line with respect to the platen roller 2 ^2. For this reason, the cut sheet S is sandwiched between the thermonole head 25 and the platen roller 22 to be fixed. On the other hand, the print data sent from the CPU 30 is converted into head drive data in the thermal head control circuit 42 and output to the thermal head 25. The thermal head 25 heats a plurality of heating elements based on the input head driving data. When these heating elements are heated while the cut sheet S is fixed, the heat-sensitive layer of the cut sheet S reacts with the heat energy to perform line printing. The printed cut paper S is further conveyed along the upper inclined surface 21b of the separation section 21 by the platen roller 22 and is discharged from the discharge section 28 to the outside of the printing apparatus 1. . At this time, the paper is discharged in a direction in which the user can see the printing surface Sa, that is, the printing surface Sa is facing upward.
