Abstract

PURPOSE:To facilitate a printing on a printing medium having an arbitrary shape, by arbitrarily moving a printing device on the printing medium. CONSTITUTION:A printing device incorporated in an easily movable small-size and light-weight frame moves by itself on a printing medium for printing. At first, the data required for printing is sent from a host device to be received by a printing data receiver 2, and all the printing data are stored in a memory 3. In printing, a timing signal is outputted from a movable sensor 4 to meet the travel speed of the printing device travelling on the printing medium. An CPU 1 reads the printing data from the memory 3, and outputs the printing data to a printing head 5 in synchronism with the timing signal outputted from the movable sensor 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dot matrix printer, and particularly to a printer with an improved printing method.

[Conventional technology]

Conventionally, this type of printing device has performed printing by moving a printing medium inside the printing device main body.

[Problem that the invention seeks to solve]

The conventional printing device described above performs printing by moving the printing medium inside the printing device, so the shape of the printing medium 1
The drawback was that there were restrictions on size, condition, etc.

SUMMARY OF THE INVENTION An object of the present invention is to provide a driver I/matrix printer which eliminates these drawbacks and can easily print on a print medium of any shape.

[Means for solving problems]

The configuration of the dot impact printer of the present invention includes a print data input section for inputting data to be printed, a memory for storing print data from this input section, and a print function for printing input print data according to a print command signal. a printing device including a head; a movement sensor that detects the movement speed of the printing device when it is moved on a print medium; and a movement sensor that outputs the printing command signal corresponding to the speed signal from the movement sensor and outputs the printing command signal from the memory. It is characterized in that it includes a processing section that reads out the print data and supplies the print data to the print head, and the printing device can move arbitrarily on the print medium.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. This embodiment is built into a small and lightweight frame that is easily movable, and prints by moving itself on a print medium. First, the print data receiver 2 receives data necessary for printing transmitted from the host device, and all of this print data is stored in the memory 3. When printing, the printing device is moved on the print medium, and a timing signal is output from the movement sensor 4 in accordance with the speed of movement. C
The PUI reads print data from the memory 3, synchronizes with the timing signal output from the movement sensor 4, outputs the print data to the print head 5, and performs printing.

〔Effect of the invention〕

As explained above, by moving the printing device over the printing medium, the present invention can print on a flat part of any shape, a part of the printing medium with a large size, or even when the printing medium is in an immovable state. It has the effect of being easy to print.
