Abstract

PURPOSE:To efficiently and unwastefully use an ink film over the full surface thereof by a method wherein a postal card is passed through only one of two halves of the ink film divided with respect to a printing width to be printed. CONSTITUTION:When a postal card is inserted to an insertion port 5 of a paper supply part 4, the postal card and an ink film 2 are synchronously run by a platen roller 7 and a film take-up roller 3 which are actuated in conjunction with each other through a motor 6 and gears. A thermal printing part 8 is depressed against the platen roller 7, and arbitrary heating elements of the thermal printing part 8 are heated to conduct a thermal transfer printing. The postal card insertion port 5 of the paper supply part 4 is constructed so that the postal card inserted from the insertion port 5 can be passed through only one (a side A) of two halves of the ink film 2 divided with respect to a printing width. In this manner, the ink film to be used firstly is taken-up by the combination of the take-up roller 3 and a take up gear 9a, whereby only the side A of the ink film is used.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a printing device used as an output terminal for facsimiles, document creation devices, various computers, and the like.

Conventional technology In recent years, thermal printing devices have been used not only for printing on thermal paper, which is often used in facsimile machines, but also for thermal transfer printing devices that use monochrome film or color film and thermal transfer paper. Since the amount of ink used is also increasing, effective use of ink film is desired.

Hereinafter, seven examples of the above-mentioned conventional printing devices will be explained with reference to the mouth side.

FIGS. 3 and 4 show an example of this principle. 1
01 is a cartridge containing an ink film 102, and the film is wound up by a winding gear 103. When a postcard is inserted into the paper feed section 104, the postcard and the ink film 102 are run in synchronization by a platen roller 2106 and a film winding roller 2107, which are interlocked via a motor 105 and gears, and the thermal printing section 10 is moved between the platen roller and the ink film 102. 106 and generates heat using an arbitrary heating element of the thermal printing section 10B, thermal transfer printing is performed.

Problems to be Solved by the Invention However, since postcards are normally fed so as to pass through approximately the center of the thermal printing section 108, that is, the center of the ink film 102, the postcards are fed as shown in FIG.
In an ink film compatible with a wide range of cut papers, only the central portion 109 is used, and both end portions are discarded unused, which poses a problem in that the ink film cannot be used efficiently.

Means for Solving the Problems In order to solve the above problems, the printing device of the present invention includes a postcard paper feed section, a thermal printing section having a printing element with a printing width equal to or more than the width of two postcards, and the printing element An ink film having a width equal to or larger than the width, 9 means for winding the ink film, and a winding system capable of winding the ink film in a direction perpendicular to the printing width, and in two directions, the printing direction and the opposite direction. When printing a postcard, the postcard passes only through one of the two halves of the ink film.

Function The present invention has the above configuration so that the postcard passes through only one of the two halves of the print width of the ink film and is printed.
Initially, the print width of the ink film was divided into two and only one half was used, but by switching the front and back of the cartridge containing the ink film, the unused part of the ink film could be used, making it possible to use the unused part of the ink film (covering the entire ink film) and making it more efficient. The film can be used without waste.

Embodiment A printing apparatus according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a printing device in an embodiment of the present invention;
FIG. 2 is a diagram showing an ink film.

In FIG. 1, a cartridge 1 contains an ink film 2 and can be wound in any direction by winding gears 9a and 9b. The postcard insertion slot 6 of the paper feed section 4 is
The postcard inserted through the insertion opening 5 passes through only one of the two halves of the print width of the ink film 2 and is printed. When a postcard is inserted into the insertion slot 6 of the paper feed section 4, the postcard and the ink film 2 are run in synchronization by the platen row 27 and film winding roller 3, which are interlocked via the motor 6 and gears, and are transferred to the thermal printing section. 8 is pressed against the platen roller 7 and an arbitrary heating element of the thermal printing section 8 generates heat, thereby performing thermal transfer printing. Here, as mentioned above, the postcard insertion slot 6 of the paper feed section 4 allows the postcard inserted through the insertion slot 6 to pass only through one of the two halves of the print width of the ink film 2 (the side in FIG. 2). Since the ink film is configured to print, the ink film initially used is wound up by the combination of the take-up roller 3 and the take-up gear 9a, and only the ink film on the A side is used. In addition, after using the ink film on the A side to the end of winding, if the front and rear of the cartridge 10 are replaced and the winding roller 3 and winding gear 9b are combined, the ink film used for printing will be replaced with the initially unused ink film. Only the other half of the print width (B (+111 in FIG. 2)) can be used.

Effects of the Invention As described above, the present invention provides a postcard feeding section, a thermal printing section having a printing element having a printing width equal to or more than the width of two postcards, and an ink film having a width equal to or greater than the width of the printing element. , a winding means for the ink film, and a car capable of winding the ink film in a direction perpendicular to the printing width thereof, and capable of winding the ink film in two directions, the printing direction and the opposite direction. When printing postcards, the postcard passes through only one of the two halves of the ink film, so initially only one of the halves of the ink film was used, and then a cartridge with a built-in ink film was used. By replacing the part after 60, it is possible to use the unused part of the ink film, and there is an effect that the ink film can be used efficiently.
