Abstract

PURPOSE:To enable more precise registration to be performed by defining a start position for writing a character by a method wherein an edge type printing means which is operated by a drive means is established, and the printing start position is arranged at a corner of a frame body. CONSTITUTION:A character to be printed and a power source are supplied from a host computer 6 by a communication cable 5, and a printing timing is controlled with a microcomputer 1 to drive a handy printer. Further, a stand- alone type handy printer can be realized by establishing a character input means in a frame body 4 instead of the host computer 6. In the case of an edge type thermal head, a glaze 13 and a heating element 14 are installed at an edge of a thermal head substrate. A printing start position is realized to be defined by using this edge type thermal head as the handy printer. By establishing the edge type thermal head 17 at the corner of the frame body, the printing start position will be capable of starting from almost the corner of the frame body as given by a printing character position 18.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for clarifying the printing start position when printing characters in a non-handheld printer [Prior Art] Printing of a conventional handy printer Due to the shape of the thermal head, the print start position was close to the center of the frame (and the print start position was also close to the center).

[Problems to be Solved by the Invention] Therefore, when printing, it is difficult to locate the beginning of characters, and a jig such as a special scale is required for fine positioning.

Therefore, in order to solve this problem, the present invention newly adopts an edge-type thermal head and sets the printing start position at the corner of the frame, thereby making the position of the start of the character's calligraphy clear and printing finer details. The purpose is to enable alignment.

[Means for Solving the Problem of Protecting the Country] The present invention provides a printer of a type in which a frame including a printing part is manually moved, which includes a) a printing control means for printing arbitrary characters on a paper surface, and b) a thermal transfer method. C) an edge-type printing means operated by the above-mentioned driving means, and the printing start position is arranged at a corner of the frame.

[Examples] Hereinafter, the present invention will be described in detail based on Examples.

FIG. 1 is a schematic diagram of a seven-day printer of the present invention.

1 is a microcomputer that serves as a printing control means for printing arbitrary characters on paper; 2 is a thermal head driver that serves as a driving means for printing by a thermal transfer method;
5 is an edge type thermal hect which serves as a printing means; 4
is a frame that holds items 1 to 5 above. As an example,
A host computer 6 supplies characters to be printed and power through a communication cable 5, and a microcomputer 10 controls printing timing and drives the handy printer. Further, by providing a character input means in the frame 4 instead of the host 6, a stand-alone type handy printer can be realized.

Here, the edge type thermal head employed in the present invention will be explained. A conventional thermal head has 11 glazes and 120 heating elements installed inside the thermal head board as shown in Figure 3, but in the case of an edge type thermal head, there are 13 glazes and 120 heating elements as shown in Figure 4. and 140 heating elements are installed at the edges of the thermal head substrate. By using this edge-type thermal head in a handy printer, it is possible to clearly define the printing start position.

FIG. 5 shows a bottom view of the printing section and the positional relationship of printed characters when using a handy printer using a conventional thermal head and when using an edge type thermal head. 15 is a conventional thermal head. Even when installed at the corner of the frame, like 16 printing character positions,
The print start position starts from the bottom of the frame. However, if the edge type thermal head 17 employed in the present invention is installed at the corner of the frame, it becomes possible to start printing almost at the corner of the frame, as in the case of the printing character position 18.

Further explanation will be made using FIG. 2. Reference numeral 7 indicates a heating element portion 8 of the thermal head at an angle between the head and the paper surface, 9 indicates a head substrate length, and 10 indicates a flexible tape connecting the thermal head driver and the thermal head. By using an edge type thermal head, even if the angle of 8 is large, the contact between the heating element part of the head and the surface of the paper can be secured, which increases the degree of freedom in connecting the flexible tape 10. Furthermore, even if the length of the board is shortened by 90, it is possible to connect 10 flexible tapes.

[Effects of the Invention] As described above, it becomes easy to align the printed characters in the handy printer, making it possible to print on small parts such as postal codes on postcards. Furthermore, even if the length of the board is shortened, it is possible to connect a flexible tape, so the board area becomes smaller and costs can be reduced.
