Abstract

PURPOSE:To enable easy positioning to an arbitrary position on a surface to be printed at the time of printing, by providing a controlling board for converting character code information into character patterns constituted of dots by using as an interrupt a clock signal obtained by counting graduations on a driving plate by a photosensor. CONSTITUTION:Tires 2 are fitted to a lower part of a main body 1. When the tires 2 are rotated, a driving plate 3 is rotated, and graduations 4 thereon are also rotated. An ink ribbon 7 is fed by rotating a reel 7a through the driving plate 3 and a belt 6, whereby an ink surface 7b is renewed. A photosensor 5 counts the graduations 4 through a wiring cord 8, and sends a clock signal to a controlling board 9. The controlling board 9 momentarily stores character code information supplied from a computer through a cable cord 10, and sends character patterns to a printing head 12 through a wiring cord 11 by making an interruption with the clock signal. The printing head 12 performs thermal transfer printing on a surface P to be printed through the ink surface 7b.

A control board that uses a clock signal counted by the photosensor as an interrupt to convert it into a dot character pattern, and a print head that is controlled by this control board and prints dot characters on the print surface via an ink ribbon by thermal transfer. It is a handy printer equipped with

[For production]

In the above-described configuration, when the handy printer is held in the hand and the surface on which printing is to be performed, such as a fixed sheet of paper, is moved, the tires of the printer rotate.

This rotation of the tire is transmitted to the drive plate in contact with the circumferential surface of the tire, the drive plate rotates, and the scale of the drive plate also rotates accordingly.

The scale of the rotating drive plate is counted by a photo sensor and sent to the control board as a clock signal.

Further, the rotation of the drive plate rotates the reel of the ink ribbon, thereby moving and updating the ink surface of the ribbon.

The control board receives character code information from a separately installed computer via a cable cord and temporarily stores it, and also interrupts clock information from the photosensor to convert it into a character pattern of dots and transmits it to the print head.

The print head prints dot characters from the control board onto the print surface via the ink ribbon by thermal transfer.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings, how the configuration of the present invention is actually embodied, together with its operation.

FIG. 1 is a diagram showing an embodiment of the present invention, and 1 is a main body of a handy printer. A tire 2 is attached to the lower part of the main body 1.

This tire 2 is rotated by holding the main body 1 of the handy printer by hand and moving the fixed printing surface P in the lateral direction.

The surface P to be printed is not limited by the size or thickness of the paper, and can also be printed on cloth or boards other than the paper.

A driving plate 3 is provided in the main body 1 adjacent to the tire 2, and the circumferential surface 3a of the driving plate 3 is in contact with the circumferential surface 2a of the tire 2 with a constant pressing force, so that when the tire 2 rotates, The drive plate 3 also rotates.

This drive plate 3 is provided with a scale 4, and the drive plate 3
When the scale 4 rotates, the scale 4 also rotates accordingly.

The scale 4 of the drive plate 3 is counted by the photosensor 5, and movement information such as the speed and distance traveled by the rotation of the tires can be obtained.

A reel 7a of an ink ribbon 7 is connected to the drive plate 3 via a belt 6.

By rotating the tire 2, the ink ribbon 7 rotates the reel 7a via the drive plate 3 and the Perutro, thereby renewing the ink surface 7b of the ink ribbon 7, so that clear printing is always possible.

The photosensor 5 counts the scale 4 through the wiring cord 8 and sends a clock signal to the control board 9 as movement information.

The control board 9 receives character code information from a separately installed computer via a cable cord 10, temporarily stores it, and interrupts the clock signal sent from the photosensor as the scale information to determine the dots. The character pattern is sent to the print head 12 via the wiring cord 11.

The print head 12 is controlled by the control board 9, receives a character pattern of dots, and prints the ink ribbon 7 by thermal transfer.
The ink is printed on the surface to be printed via the ink surface 7b.

The surface P to be printed is not limited by the size, thickness, quality, etc. of the paper (and may be a flat surface of cloth, a board, or any other material from which the paper is removed).

Figure 2 shows the character pattern and shows the column (CO
L) Consists of 8 columns from 0 to column 7.
