Abstract: A line thermal head printer device of which size is made remarkably smaller is provided. A stepping motor (10) rotationally driving a ribbon tape reel is arranged to be fitted to one corner portion of a frame plate (9). A line thermal head (11) is arranged to be fitted to a corner portion of the frame plate (9) adjacent to this one corner portion. A ribbon tape winding drive shaft (2) and a ribbon tape unwinding drive shaft (1) are arranged on one side of the stepping motor (10) and the line thermal head (11), respectively, to be fitted to the frame plate (9). By this arrangement, parts and components are efficiently arranged without unused space on a surface of the frame plate (9) of a square or rectangular shape. Also, a ribbon tape (3) fed between reels fitted to the drive shafts (1, 2) is led around the parts and components, that is, along a periphery of the frame plate (9).

Abstract: Letter printing method using line thermal head relates to using ribbon tape effectively so as to cause no unused portion thereof. After one letter print (14) is done at letter printing position (12) of packaging material film (10) with the ribbon tape (30) being unwound, the ribbon tape (30) is rewound by length of the letter print (14). Simultaneously, the ribbon tape (30) is displaced in ribbon tape widthwise direction and next letter print (14) is done. Thereby, the letter print (14) may be done using entire width of the ribbon tape (30) with no unused portion being wasted.

Abstract: Line thermal head letter printing method is improved to feed ribbon tape synchronously with transfer velocity of print object sheet from immediately after start of printing so as to obtain high quality letter printing. Ribbon tape master roll (6) is driven by stepping motor (18) so as to feed necessary amount of ribbon tape (4). Ribbon tape winding roll (8) is driven via friction transmission so as to wind the ribbon tape (4) at velocity higher than that of transferring print object sheet (2). There occurs no loosening of ribbon tape hot release portion at tip of line thermal head (10) and high quality letter printing is obtained.

Abstract: In a line thermal head printer apparatus, a ribbon tape is moved, only while printing is to be made, synchronously with the moving velocity of the object to be printed. The ribbon tape is moved only by the amount needed for printing and the amount of use of the ribbon tape is reduced and yet a beautiful printing is made. Ribbon tape 2 unwound from a heat transfer ribbon tape master roll 1 is lapped with a packaging material film 8 on a platen roller 6 and printing is made by a line thermal head 5 on the packaging material film 8. The ribbon tape 2 is stopped by a braking action making use of a maximum static torque characteristic of a stepping motor until a portion to be printed of the packaging material film 8 approaches, and is moved by the stepping motor only when the portion to be printed of the packaging material film 8 arrives.
