Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information output device for editing text, and more particularly to an information output device for editing that moves a print head and a cursor to a character correction position.

In conventional printers and displays for editing, in order to move the print head or cursor to the corrected location such as correcting, erasing, or adding characters, you press the back or forward base key to move the print head or cursor one character at a time. was.

For this reason, it takes a long time for the print head and cursor to reach the desired correction location, and the operator is mentally fatigued because he or she must press keys while constantly watching the current position of the print head and cursor. There were drawbacks such as. The present invention is intended to eliminate the above-mentioned drawbacks, and is designed so that the print head or force-sol can be moved to the corrected point simply by inputting the character at the corrected point after pressing the backs bass key or the forward doss bass key. It is.

The present invention will be described in detail below with reference to the drawings.

Note that the following explanation is for the case where the information output device is a printer, but the same applies to the case of a display device.
FIG. 1 is a block diagram showing an example of printing of a text to be edited, and FIG. 2 is a block diagram showing an example of a movement control circuit for moving the print head to a correction location.

In FIG. 2, 1 is a flip-flop set by the forward base key press signal FSP, 2 is a flip-flop set by the back base key press signal P, and 3 is a forward base key press signal FSP. Or the character data KD input after pressing the BACKS BASE key.
4 is a collation circuit that collates the stored contents of the register 3 with the read data RD from the editing memory 5 to detect a match or mismatch; 6 is a collation circuit that collates the set output signals of the flip-flops 1 and 2 with the data RD read from the editing memory 5; A movement command control circuit sends a movement command signal and a direction control signal based on the match signal and mismatch signal from the circuit 4; 7 is a drive control circuit for a pulse motor that is a drive source for moving the print head; 8 is a line data LD; This is an address designation circuit that designates the address to be accessed in the editing memory 5 based on the column data CD of the column counter 9.

In the editing memory 5, character data input by keystroke is stored at addresses corresponding to print columns in a storage area divided into rows. The column counter 9 counts up each time the count pulse CP arrives when the print head moves in the forward direction (when the forward signal FWD is applied) and when the forward base key is pressed. It is a reversible counter that counts down every time a count pulse CP arrives when a key is pressed. Next, as an example, a case will be described in which, for an edited text as shown in FIG. 1, the print head is at position P, and the print head is moved to position P2 for inserting additional characters. First, the operator presses the print head to P.
, to return to the P2 position, and then press the character "1" printed at the position where you want the print head to stop.

The pressing of the backs bass key is memorized by the flip flip 2, and the character code of the keystroke input data ``1'' is stored in the register 3 by the key pressing signal K of the character key ``1'' thereafter.
is set to

On the other hand, based on the set output of the flip-flop 2, the movement command control circuit 6 sends out a direction command signal and a movement command signal instructing the pulse motor to reverse direction, thereby rotating the pulse motor in the opposite direction and moving the print head in the opposite direction. . A count pulse CP is supplied to the column counter 9 every time the print head moves one column. The column counter 9 counts down by "1" each time the count pulse CP arrives due to the output "B" of the flipflop 2. Further, since the line data LD is on the line that the print head wants to correct, there is no need to specify it. Therefore, the editing memory 5 is accessed by the address designation circuit 8 in order from the address of the last print column in that row, and each time the print head moves one column to the left, the read signal R reads out the character code in the reverse order of printing. . The read data RD of the editing memory 5 is compared one after another with the character code "1" stored in the register 3 in the collation circuit 4, and if they do not match, a mismatch signal is sent to the movement command control circuit 6 and the print head is continues to move to the left. When the print head reaches position P3, the character code "1" is read from the editing memory 5,
A matching signal is sent out from the matching circuit 4.

The movement command control circuit 6 thereby sends a stop signal to stop the print head. Also, the flipflop 2 is reset. Here, the operator again presses the key ``BACKS BASE ``1'', and the above operation is repeated again, and this time the print head stops at position P2.

In this way, the print head is moved to the desired correction point by pressing the backs-base key and the character key, and then the correction work of additional insertion is started. If the print head is located to the left of the correction location, press the forward base key, and then press the character key printed at the desired position.

The flip printer lip 1 is set by pressing the forward base key 1, and the movement command control circuit 6 sends out a direction control signal and a movement command signal to move the print head to the right.
On the other hand, the column counter 9 now performs a count-up operation and reads character data from the editing memory 5 in the same order as in printing. Thereafter, the content held in the register 3 and the draft data in the editing memory 5 are compared in the same manner as above, and when the two match, the print head is stopped. If the print head is not at the line position you want to correct, press the function key to specify the line and the numeric key to specify the line number, read the desired line from the editing memory 5, print it, and then perform the same operation as above. conduct.

As explained above, according to the present invention, in order to move the print head to the target correction location, it is only necessary to first press the forward base key or the back base key and the character key. The arrival time of the print head is shortened, and the burden on the operator is greatly reduced.
