Abstract

PURPOSE:To contrive to increase the number of types, by constituting the titled apparatus so that an alphabet (S or Y) and a mark (I or =) are printed in a separated state when characters of $ or Yen are printed and, after either one of them is printed, overlapping prining is performed to move a carriage to the next printing figure. CONSTITUTION:When the printing character inputted from a keyboard 1 is a dollar mark $, a control circuit 2 selects the S-character of an alphabet to print the same and subsequently selects a mark ''I'' to print the same at the same position without moving a carriage. Then, the control circuit 2 allows the carriage to move to the next printing figure to bring the same to a stand-by state. When a yen mark Yen is inputted, the control circuit 2 prints the Y-character of an alphabet and subsequently prints an equal mark ''='' in an overlapped state to enable the printing of the yen mark Yen. By this method, the increase in the number of types received in a daisy wheel can be achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a printing device such as an electronic typewriter or printer that prints using a daisy wheel.

(b) Conventional technology Recently, for example, a daisy wheel as shown in Japanese Patent Publication No. 52-19490 has been used to control type selection, margin setting, tab functions, etc. with a microprocessor, resulting in multifunctionality. The spread of electronic tamp lighters has been remarkable, and daisy wheels are now equipped with alphabets, English symbols,
By providing special characters or symbols other than alphanumeric characters, it is configured to be compatible with several languages. By the way, the daisy wheel can accommodate about 100 characters, but if you want to increase the number of characters, you will need to increase the diameter of the daisy wheel and the device will become larger, so it is necessary to increase the number of characters. It wasn't easy.

(C) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned points, and by printing special characters using a combination of two types, and omitting the dedicated type, It is an object of the present invention to provide a printing device configured to increase the printing capacity of the envoy.

2) Means for solving the problem In the present invention, for example, special characters such as $, ¢, etc. are not provided with dedicated typefaces, but are instead used with the English letters S, C, Y and the symbols "゛," -.
It is configured to print by a combination of the following.

(E) Function Since the present invention is constructed as described above, the alphabetic characters s, c, and y are printed first, and then the symbols "I" and "=" are printed.
By overlapping and printing, $ and q1\ are printed.

(f) Example Embodiments of the present invention will be described below with reference to the drawings.

(1) is a keyboard that can be composed of alphabet keys, alphanumeric keys, symbol keys, etc., and the key signals are sent to the control circuit (2).
has been entered. The control circuit (2) is comprised of a microprocessor which, upon receiving a key signal, performs control according to a program stored in a program memory (3) in which a processing program is stored in advance. (4) is a storage device in which inputted key data, margin data, tab data, etc. are stored, and the control circuit (2) is used to write and read data.
controlled by. (5) is a daisy wheel, /
- The printing mechanism is composed of a carriage on which a printer, etc. is mounted, a carriage drive mechanism, etc., and is driven and controlled by a control circuit (2).

Next, the operation of the present invention having such a configuration will be explained based on the flowchart shown in FIG.

First, when a character to be printed is pressed manually from the keyboard (1), the control circuit (2) that receives the key signal
It sequentially determines whether the input key is $, ¢,
If neither of these is the case, after determining the position of the input character on the daisy wheel,
The printing mechanism (5) is controlled to drive the motor and control the rotation of the daisy wheel so that the printed characters come to the printing position.Then, when the printed characters arrive at the printing position, the hammer is driven and the printed characters are struck against the platen. As a result, printing is performed on the recording paper. When printing is completed, the control circuit (2) moves the carriage to the next printing digit and then enters a standby state for the next print input. In this way, the key input from the keyboard (1) is performed manually. Each time the printing is performed, the control circuit (2) repeats the above-mentioned operation to perform printing.

Next, a case will be explained in which the print character input from the keyboard (1) is a dollar sign ($). The control circuit (2) detects that the printed character that has run out of key power is a dollar sign (lit).The control circuit (2) first selects and prints the letter S in the alpha field, and then prints it at the same position without moving the carry key. Next, select and print the symbol “B”. This will add the symbol “I” to the S character.
11 are printed overlapping and the dollar sign (Il) is printed. When the symbol "I ++" is printed, the control circuit moves the key to the next printing digit and waits for the next printing input. Similarly, when the cent symbol (g) is input, the alphabet C is first printed, and then the symbol "I" is overprinted to create the cent symbol (g).
) is printed. Furthermore, in the case of a yen symbol (¥), the yen symbol (¥) can be printed by printing the alpha hent Y and then overprinting the equal sign “= ++.In this way, at least $, ¢, number Since the second type does not require a special type, it can be used for other type and increase the number of type.In the example, alphabets 51C and 51Y are printed first. The symbol “B”
Although the configuration was configured to print 71 = 11, the reverse may also be used).

(G) Effects of the Invention As described above, the printing device of the present invention does not provide dedicated type for characters that can be printed in combination, such as $, ¢, etc., and prints by overlapping printing in two times. This structure increases the number of characters that can be accommodated in the tissue wheel, and although the printing speed is somewhat slower than those with dedicated characters, it has the great effect of increasing the number of characters. This is useful for printing devices that use daisy wheels.

Claims (1)

[Claims] (1) When printing characters such as $, ¢, ¥ on a printing device that uses a daisy wheel, the alphabets (S, C, Y) and symbols (I, =) are printed separately. 1. A printing device characterized in that, after printing either one, the carriage is not moved, but the other is overprinted and the carriage is moved to the next printing column.
