Abstract

PURPOSE:To provide a typewriter which is capable of printing symbols such as comma for each line while eliminating automatic return shift when the final character of a line is printed, by performing only shaft feeding without space feeding each time printing is performed whe printing is made in the automatic shift mode. CONSTITUTION:A mode selection switch 23 for alternatively selecting the automatic return shift and the automatic shift is communicated to a CPU3 so that only the shift feeding is allowed without space feeding each time printing is performed when printing is made in the automatic shift mode. The printing of a table or the like with period, comma, number or the like at the same position of lines can be performed simply by the normal printing operation only with the switch 23 set to the automatic shift mode. This allows the printing without setting it to the automatic return shift even at the end of the line thereby facilitating the working of tabulation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to typewriters, such as Japanese typewriters, on the electronic side.

When tabulating a table using a typewriter, for example, when printing horizontal rows of numbers in several lines vertically, it is necessary to align the digits of each row vertically, but the comma symbol that indicates the digit of each row and the symbol before and after it. Because the distance between letters and numbers is different, if you print according to the order of letters, you will have to change the platen feeding pitch several times during the printing process.
The work is complicated because it is necessary to align the position with the previous row.

In view of the above points, the first aspect of the present invention is to make symbol parts such as commas blank by using tab settings, for example, and after printing each line, print the comma in the symbol parts such as commas. Each time a symbol such as , etc. is printed, it is possible to print a symbol such as a comma on each line by only performing a line feed without performing a character inter-character feed, so that an automatic return is not performed when this operation is performed for the last character. The purpose is to provide a typewriter with a

In addition to the above-mentioned object, the second aspect of the present invention is a type in which the indicator that indicates the distance traveled from the reference point during normal printing work also shows the distance moved from the reference point during the line feed work. The purpose is to provide writers.

Embodiments of the present invention will be described with reference to the drawings.

1 is a print key 11. A keyboard equipped with space keys 12 and 13, which is movably installed in a normal Japanese typewriter integrally with the index handle. 2 is an operation panel equipped with switches and indicators for setting conditions; 21 is a digital switch for setting character spacing; 22 is a digital switch for setting line spacing; 23 and 24 are mode switching switches; By switching 23, there are 3 types: "Automatic return", "Normal character spacing (OFF) J", and "Automatic line feed".
One of the modes is alternatively selected, and switch 24 selects
You can choose whether or not to use equal allocation based on plant quality. 25 is a platen feed indicator for indicating the moving distance from the reference point in the inter-character direction or the moving distance from the reference point in the inter-line direction. 3 is a central control unit, each of the switches 21, 22, 23, 24 and each key 11, 12;
The status of each switch 21, 22, 23, 24 is constantly monitored by the typist 13 and the platen feed indicator 25, and when the typist finishes typing and presses the print key 11, the type bar (not shown) is displayed. ), read the setting status of each switch 21, 22, 23, and 24 on the operation panel 2, calculate the direction and distance of the platen feed, and then turn the horizontal feed pulse motor 4 or the vertical feed when the marking is finished. A rotation control signal is sent to one or both of the pulse motors 5 at the same time, and the platen is moved between characters and between lines during printing. 61 to 68 are interfaces that relay between the central processing unit and each peripheral device. , When printing is performed by pressing the print key 11 with the mode conversion switch 23 in the automatic line feed mode, only line feed is performed without intercharacter feed, and at the same time, the line feed is performed in the character spacing direction from the reference point. The platen feed indicator 25, which had been showing the moving distance, is converted to show the moving distance from the standard in the inter-line direction.

For electronically controlled Japanese type writers, when setting the platen feed associated with printing, setting the character/line spacing is easier than setting the vertical/horizontal feed. The reason for this is that the length of the line (character spacing) is fixed, and if symbols of a size other than that of academic conferences, Roman letters, numbers, etc. are mixed in, the length of the line between the letters is lengthened or shortened little by little. You have to adjust the end of the lines so that they line up.
In order to adjust this, a means to slightly increase or decrease the character spacing setting value is required. Rather than changing the standard character spacing setting value itself, it is necessary to make small corrections to the standard value to adjust the situation (such as platen feeding as printing progresses). It is desirable to calculate and display [how many characters and how many points are fractions], and for this reason, a separate means for setting minute correction values is provided, and "vertical/horizontal feed settings" can be set using [character spacing/line spacing settings]. ] This is because the system configuration becomes more complex.

When printing a numerical table, do not use ``decimal point'' or ``comma every 3 digits''.
must align the line positions.

According to an embodiment of the present invention, when the same numbers are arranged at the same position of a dot, a comma, or between lines, it is possible to locally print perpendicular to the line without performing a line break feed without performing a feed in the direction between characters. Mode conversion between normal feed and line feed for each print can be performed by switching the 1B switch. Also, normally, a switch is required to select whether or not to automatically return at the end of a line, but carriage return is unnecessary for the line feed described above, and it is always necessary to
Automatic recovery must be turned off. Therefore"
The selection switch for the "Automatic line feed" mode should be a separate contact on the same switch as the "Automatic line feed" mode selection switch, or an interlocking type should be used.

[Automatic line feed] No matter where in the line the line is printed, it is not moved in the direction of the line each time it is printed, but only a line feed is executed. Therefore, the display of the platen position shows where it is currently located.

should be shown. Normal printing shows the number of characters and fractions from the reference point within a line (beginning or end of line), so when switching to "automatic line feed" mode, the position in the line spacing direction is indicated by how many lines and fractions from the first line. It is desirable to convert it into a display. In reality, there is no need to increase the number of switch contacts, and the central control unit f3 only needs to convert the display mode, but from the typist's perspective, the display also appears to be switched in conjunction.

As described above, the first aspect of the present invention is that the print key, the character spacing switch, and the line spacing switch communicate with the central controller to perform unit character spacing and line spacing of the platen during printing, respectively. When printing in automatic line feed mode with a mode change switch that selectively selects automatic return or automatic line feed,
It is characterized in that it communicates with the central control unit so that only a line feed is sent without inter-character feed in the margin of printing, so it is a number that has the same character, dot, comma, number, etc. in the same position between lines. When printing tables, etc., you can simply set the mode switch to automatic line feed mode and use normal printing operations to easily print tables, etc., and when working at the end of a line, you can do it without having to automatically start a new line. , this can be executed, making tabulation work easier for typists.

Furthermore, a second aspect of the present invention, in addition to the first configuration, automatically controls a platen position indicator communicated with a central controller to indicate the distance traveled from a reference point in the inter-character direction. When printing in line feed mode, the line spacing direction is converted to indicate the moving distance from the reference line, so in addition to the effect of the first invention, the position in the line spacing direction is automatically displayed. , it is possible to know the line position of the printing place.
