Abstract

PURPOSE:To make possible the entry of printing data using various application methods and thereby the manufacture of a compact and light-weight device by installing an interface for a host device and setting a memory card holder. CONSTITUTION:Data which is entered from a keyboard 11 of a terminal 1 or data which is written in a memory card 23 inserted in a memory card holder 22 is totally stored in a printing data buffer 23 through an interface section 25, if data is entered through the keyboard. Of data stored in the memory card and the printing data buffer 23, printing equal to a single line is stored in a printing data memory 24. Data to be printed next on a medium is stored in the printing data memory 24 by placing a thermal transfer printing section 21 on a medium to be printed and moving this device. Consequently, it is possible to manufacture a light-weight and compact printer.

Description

[Detailed description of the invention] Industrial applications TECHNICAL FIELD This invention relates to portable printing device systems.

BACKGROUND OF THE INVENTION Conventionally, printing apparatus systems of this type have taken the form of a large-sized system that is fixedly installed on a terminal.

Problems to be Solved by the Invention The conventional printing system described above is large and heavy, so it can only be installed fixedly on a terminal, and the data sent to the printing system is not logical. The drawback is that it can only be sent from connected devices.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a novel portable printing device system which makes it possible to overcome the above-mentioned drawbacks inherent in the prior art.

Means for Solving the Problems In order to achieve the above objects, a portable printing device system according to the present invention includes a host device for inputting print data, a memory card holder for reading data on a memory card, and a memory card holder for reading input print data. It has a print data buffer for storing data, a print data memory, and a thermal transfer printing section.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to the first section, reference number 1 indicates a terminal which is a host device, and 11 indicates a data input keyboard. Reference numeral 2 designates a portable printing device, of which 21 is a thermal transfer printing unit that performs printing, 22 is a memory card holder into which a memory card is inserted, and 23 stores print data read from the memory card and terminal 1, which is a host device. 24 is a print data memory for storing one line of print data, and 25 is an interface section between the terminal 1, which is a host device, and this printing apparatus.

In the case of keyboard input, all data input from the keyboard 11 of the terminal 1 or data written to the memory card 23 inserted into the memory card holder 22 is stored in the print data buffer 23 via the interface section 25. . Among the data stored in the memory card and print data buffer 23, the corresponding one line of print data is stored in the print data memory 24.

Printing is performed on the medium by placing the thermal transfer printing unit 21 on the medium to be printed and moving the apparatus. After one line of printing is completed, the print data buffer 2
The data to be printed next from 3 is stored in print data memory 2.
It is stored in 4.

As described in detail, according to the present invention, by providing an interface with a host device and setting a memory card holder, it is possible to input print data using a variety of methods. In addition, after inputting data, the host device and memory card can be removed, and the printing device itself can be moved over the printing medium, making it lightweight and compact, making it easy to print anywhere. This has the effect of making it possible.
