Abstract

PURPOSE:To rapidly perform slip treatment by printing an amount of money while calculating the same corresponding to input such as unit cost data, by mounting decimal tab function and calculating function. CONSTITUTION:A document due to a keyboard 1 is repeatedly printed by a printing apparatus while stored in an one-page memory circuit 5 through a control circuit 2 for performing process control corresponding to the program of program memory 3. On the other hand, when the position of a decimal point due to the tab set key of the keyboard 1 is indicated, a carriage, to which a printing mechanism is mounted, moves to the position of the decimal point and a unit mark data is stored in the circuit 5 along with a tab position by the operation of the tab set key. When a figure is indicated by the decimal tab key of the board or multiplication is indicated by the multiplication key thereof, multiplication operation and carriage movement are controlled by calculating function and decimal tab function through decimal tab memory 6 for storing an indicated tab position and the circuit 2 to print a unit cost, quantity or an amount of moeny and slip treatment is rapidly performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic typewriter equipped with a decimal tab function for aligning decimal point positions and a calculation function.

(b) Prior Art Recently, electronic typewriters with various editing functions controlled by microprocessors have been developed and commercialized.One of the editing functions is to align the decimal point position when printing numerical data. , a decimal tab function is provided that makes it easier to see the number arrangement.

By the way, in most cases, the unit price, quantity, and amount are printed in the order of the unit price, quantity, and amount, so if the amount could be automatically printed just by inputting the unit price and quantity, the processing of the voucher would be faster and more convenient. However, no conventional electronic typewriter had this kind of functionality.

(c) Object of the Invention The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide an electronic typewriter equipped with a decimal tab function and a calculation function.

B)) Structure of the Invention The present invention is configured such that when unit price and quantity data are input, the amount is automatically calculated and printed at a predetermined position on a slip or the like.

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

(1) is an electronic typewriter keyboard with number keys,
It consists of alphanumeric keys, special symbol keys, etc. (2) is a control circuit that reads input data from the keyboard (1) and performs control according to the human power of the keys.It is composed of a microprocessor, and peripheral devices are controlled according to the program in the program memory (3) in which the processing program is stored. is controlled. In addition, the control circuit (2) is connected to the keyboard (
When the calculation key 1) is operated, a predetermined calculation is performed. (4) is a printing device consisting of a type wheel, a hammer, a paper feed mechanism, etc. It is a storage device that has a capacity to store one page of type based on the control of the control circuit (2), and can be written and printed continuously. It is controlled by a control circuit (2), and the stored document data is read out from the printing device f.
(41), it is possible to create any number of copies of the same document. Note that this storage device f (51) is configured to also store function data such as tab position data. (6) is a keyboard The decimal tab memory stores the data input after the decimal tab key (1) is operated until the decimal tab release key is operated, and the writing and continuous output of data is controlled by the control circuit (2). The printing device (4) is configured not to print when the decimal tab memory (6th data) is input.

Next, the operation of the present invention having such a configuration will be explained with reference to the flowchart shown in FIG.

First, when document data is input sequentially from the keyboard (1) normally, the document data is immediately taken into the control circuit (2), and is stored in the storage device (5) at the same time as printing is performed by the printing device (4). Ru.

If you need to enter numerical data to print on a slip, etc., first set the decimal point using the keyboard (1).
After specifying it with the tab select key, operate the decimal tab key on the keyboard. In other words, the carrier on which the printing mechanism is mounted
When the tab set key is operated after moving the carriage to the decimal point position using the space key, the position of the carry carriage is stored in the storage device (5) as a tab position. For example, now 9
As shown in Figure J2 (a), set the tabs at three points A, B, and C as decimal point positions, and set the unit price, quantity, and amount as shown in Figure 2 (a).
We will explain the case of printing as follows. At this time, since the signals "@" and "¥" are printed at the beginning of the unit price and amount, respectively, when setting the tab, the "@" or "
\" key is operated to store the unit symbol data together with the tab position data in the storage device (5).

So, when these settings are completed, next operate the decimal tab key to move the carry rigidity to point A of the tab position, enter J500J, and then press the multiplication key, which is one of the decimal tab release keys. When "x" is operated, the control circuit (2) which has received the decimal tab release key signal first detects whether or not the "@" symbol has been set. In this case [tab position where 500J is printed (
Since "@" data is set at point A), "50" of the input data entered in Decimal Tab Memo January 6)
Write the "@" data to the upper digit of "0", then calculate the number of digits of data in the decimal tab memory (6), and then calculate the amount of movement of the carry rigidity from the current carry rigidity position, that is, the tab position. After calculation, the carriage is moved one printing position under the control of a motor (not shown) that drives the carriage, and then printing is performed. In this case, the decimal tab memory (6) contains “
Since 4 digits including the ``@'' data are stored, the carrier IJ t+7 is moved to the position of point A, which is 4 digits to the left after point A of the decimal tab position, and printing starts.
It is printed as shown in the figure (bl).

At this time, by operating the multiplication key "x", data l'-500J input to the decimal tab memory (6) is transferred to the calculation register in the control circuit (2).

Next, after operating the decimal tab key in the same way as above to input the number 1, enter the numerical data "20".
The carry rigidity is moved to the next tab position, point B, and the input data is stored in the decimal tab memory (6). When you have finished inputting, press the calculation key "=" of the decimal tab release key, and a "
It is determined whether data of "@" or "\" is set. In this case, nothing is set at the decimal tab position of point B, so immediately do the same as above to set "20" of the data stored in the decimal tab memory (6).
is printed. Following the end of printing, the control circuit (2) calculates l'-50 of the unit price data stored in the calculation register in advance.
0J and the quantity data "20" stored in the decimal tab memo January 6), the calculation result is stored in the decimal tab memo January 6), and the carriage is automatically moved to the 0 point of the next tab position. After moving it to , check whether a unit signal is set at the decimal tab position in the same manner as described above, and print [\IGGOOJ].

In this way, by simply inputting unit price data and quantity data, the amount can be automatically printed at a predetermined position.

It is possible to automatically print out the calculation results.

(f) Effects of the Invention As mentioned above, the electronic typewriter of the present invention is equipped with a decimal tab function and a calculation function, so that when unit price and quantity data are input, for example, the amount is automatically calculated and printed. It is suitable for printing slips, etc., and has effects such as speeding up slip processing.
