Abstract

PURPOSE:To obtain a handy printer small in side, inexpensive and enabling the use of a special tape as an ink ribbon by providing a guide roller for discharging an ink ribbon and a cutter part for the ink ribbon. CONSTITUTION:An ink of an ink ribbon 11 used in a thermal transfer type handy printer is transferred onto a paper surface 10 by heat generated by a thermal head 5. As the handy printer is moved, the used ink ribbon 11 is discharged rearward by an amount corresponding to the movement, but no mechanism is provided for taking up the used ink ribbon. The used ink ribbon is held between fingers, and is pressed against an ink ribbon cutter 6 while drawing the ribbon rearward, whereby the ribbon is cut. A guide roller 7 for discharging the ink ribbon 11 prevents the ribbon 11 from protruding from a printing area during printing, and prevents the ribbon 11 from drooping from a main body after the printing. Thus, a single tape reel suffices, and there is no need for a tape take-up mechanism. Therefore, the printer can be produced in a smaller size and inexpensively, and a special tape can also be used because it is unnecessary to take up the tape.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for winding up a used ink ribbon for a handy printer that performs manual printing.

[Prior Art] A conventional handy printer has two ink ribbon reels. An unused ink ribbon was wound on one reel, and a used ribbon was wound on the other reel after printing.

[Problems to be Solved by the Invention] However, the above-mentioned conventional technology requires a complicated winding mechanism using gears or the like to wind up the used ink ribbon. Also, two ink ribbon reels were required, the ink ribbon case was large, and special tapes such as those made of thermal paper could not be used as ink ribbons. The conventional technology has the above-mentioned problems.

SUMMARY OF THE INVENTION The present invention is intended to solve these problems, and its purpose is to provide a small and inexpensive handy printer that can use a special tape as an ink ribbon.

[Means for Solving the Problems] The handy printer of the present invention is characterized in that it does not have a used ink ribbon winding mechanism because it has an ink ribbon discharge guide roller and an ink ribbon cutter section.

[Function] According to the above configuration of the present invention, a single ink ribbon reel is required, a used ink ribbon winding mechanism is not required, and a special tape can also be used as an ink ribbon.

[Example] FIG. 1 is a front view of a thermal transfer type handy printer of the present invention. The printing operation is performed by pressing in the direction of arrow 1 on the paper surface 10 and moving in the direction of arrow 2, and the state is shown at °C.

5 is a thermal head that can move up and down and is held down by a spring so that it can come into close contact with the paper surface 10.

A driving wheel 4 detects the amount of rotation and generates printing pulses.

3 is a removable ink ribbon reel on which an unused ink ribbon 11 is wound. Place the ink ribbon 11 and ink ribbon reel 3 in a suitable ink ribbon case °C.
It's okay to have one. The ink ribbon 11 is a thermal head '5
The ink is transferred to the paper surface 10 by the heat generated. The used ink ribbon 11 is pulled by the operator's hand, and as the handy printer moves, the handy printer moves and is probably ejected to the rear (leftward in the figure).

There is no mechanism to wind up the used ink ribbon.

A guide roller 9 serves to move the printer linearly and stably.

13 is a circuit board, which is a driver I of the thermal head 5;
It consists of C, etc.

Reference numeral 14 denotes a cable, which is used when supplying print data and power to the printer from a word processor, personal computer, or the like.

Reference numeral 8 denotes an ink ribbon guide roller that prevents the ink ribbon 11 from protruding beyond the printing area.

When the thermal head 5 that presses the printer body against the paper is pushed up by the paper and moved, the lever 12 rotates and separates from the ink ribbon reel 3, making the ink ribbon reel 3 rotatable.

When the printer body is released from the paper, the lever 12 returns to its original position and fixes the ink ribbon reel 3.

Reference numeral 6 is an ink ribbon cutter, and while holding the used ink ribbon with your hand and pulling it backwards, cut the ink ribbon cutter 6.
The ink ribbon is cut by pressing it against it. At this point, the ink ribbon reel 3 is fixed by the lever 12, so the ink ribbon does not come out on the ♀ meter. The ink ribbon cutter 6 is made of resin and has obtuse-angled peaks shaped like a saw so that it is safe to touch. The ink ribbon cutter may be made of metal or the like.

7 is an ink ribbon discharge guide roller, and the ink ribbon 11
This prevents the ink ribbon 11 from protruding from the printing area during printing, and prevents the ink ribbon 11 from becoming heavier than the main body after printing is completed. Since the ink ribbon discharge guide roller 7 and the ink ribbon cutter 6 are separated by 20 mm, when the ink ribbon is cut, 20 mm of the ink ribbon remains on the main body side. To easily pinch an ink ribbon by hand during the next printing.

FIG. 2 is a bottom view of the thermal transfer handy printer of the present invention.

In this embodiment, the ink ribbon is made of ink and a base, but various tapes such as a thermal paper tape or a two-layered tape made of a paper tape and an ink ribbon can be used. The above tape may have an adhesive material or a release paper attached.

[Effects of the Invention] As described above, according to the present invention, by configuring the ink ribbon discharge guide roller and the tape cutter section in the printer, the tape reel can be integrated into one. Since a complicated tape winding mechanism such as a used tape winding reel or a rotation transmission gear is not required, the printer can be made smaller and manufactured at a lower cost.

Furthermore, since there is no need to wind it up, the following special tapes can also be used.

A tape made of thermal paper, adhesive material, etc. A two-layer tape made of O paper tape and an ink ribbon These can be printed on the tape, cut out and placed in any position. With conventional handy printers, it was difficult to accurately determine the printing start position, but if the handy printer of the present invention prints on the tape as described above, printing can be done accurately and easily.
