JPH078585B2 - Hand scan printer - Google Patents

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand scanning printer (also referred to as a handy printer) for holding a print head by hand and applying it to a paper surface for printing.

<Prior Art> A hand scanning printer is used in combination with, for example, a word processor or the like, and prints a character string input in the word processor on a paper surface. Can be printed in position.

<Problems to be Solved by the Invention> In the conventional hand-scanning printer, since a character string that can be printed in one scan is only one line, the number of scans is large when a large amount of text is printed. However, there is a problem that the work is complicated, it takes time, and the hands get tired.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a hand-scanning printer capable of printing a character string of two lines by one scanning.

<Means for Solving the Problems> In order to achieve the above object, in the manual scanning printer according to the present invention, mode setting means for selectively setting either one-line printing mode or two-line printing mode, Printing processing means for giving to the print buffer the character pattern data for the input character string data for printing one or two lines according to the setting by the mode setting means, and printing according to the setting by the mode setting means It is characterized by comprising a print head for printing a character string for one line or two lines stored in the buffer.

<Operation> In the manual scanning printer according to the present invention, in the two-line printing mode, two lines of character pattern data are written in the print buffer, and the print head of two lines is written in accordance with the two-line character pattern. The dots are simultaneously conductive. Therefore, when the user holds the print head by hand and scans the paper surface, a character string for two lines is printed. The one-line printing mode operates in the same manner as a conventional manual scanning printer.

<Embodiment> FIG. 1 shows a configuration in which the hand-scan printer of this embodiment is combined with a word processor. In the figure, 1 is a mode setting unit, 2 is a print processing unit, 3 is a print buffer, 4 is a print head, 5 is a keyboard, 6 is a character data input unit, and 7 is a character data edit processing unit. In the figure, the part surrounded by the broken line constitutes the hand-scanning printer,
Other than that, it constitutes a word processor.

The mode setting unit 1 selectively sets each mode of one-line printing or two-line printing. This is done according to the operation of the user. The print processing unit 2 stores the character code data given from the word processor in the character code storage buffer, reads the character pattern data corresponding to the character code from the built-in character generator, and according to the setting of the mode setting unit 1, one line Alternatively, the character pattern data for two lines is sent to the print buffer 3. The print buffer 3 stores one line or two lines of character pattern data corresponding to the dots of the print head 4. Print head 4
Is energized to each dot according to the print pattern data given from the printer buffer 3, and one line or 2
Print a string of lines.

The keyboard 5, the character data input unit 6 and the character data edit processing unit 7 constitute a word processor. The character data input unit 6 generates a key code of a character input from the keyboard 5. The character data edit processing unit 7 performs an edit process on the input character string and outputs a character code corresponding to the edited character string.

FIG. 2 shows an operation mode of the print head 4, and printing is 24 × 24 dots. (A) is the one-line printing mode,
Of the total 64 dots, the central 24 dots work. Further, (b) is a two-line printing mode, and 24 dots on both sides are operated. In each case, scanning in the direction of arrow A prints a character string of one line or two lines.

FIG. 3 conceptually shows the contents of the print buffer 3, and in the 2-line print mode, character pattern data is stored in the first line character string buffer 3a and the second line character string buffer 3b of 24 dots in the vertical direction. Each is written.

FIG. 4 shows an operation procedure in the two-line printing mode. First, the display device of the word processor becomes an input screen and is in a key waiting state for character input. Here, the character string on the first line is input from the keyboard 5 (step #
1) and the character code of the input character string are stored in the character code buffer (# 2). Then, when the character string of the second line is input (# 3), the character code of this character string is stored in the character code buffer (# 4). Next, the character pattern data corresponding to the character codes for two lines stored in the character code buffer is read from the character generator, and this character pattern data is written in the print buffer 3 (# 5). After that, the character pattern data is given from the print buffer 3 to the print head 4, and printing for two lines is performed (# 6).

The operation of the one-line printing mode is the same as that of the conventional manual scanning printer, and the description thereof will be omitted.

<Effects of the Invention> As described above, according to the present invention, two scans are performed.
Since it is possible to print lines, a large amount of character strings can be printed in a short time with a small number of scans.
Fatigue due to work can be reduced.
