Abstract

PURPOSE:To simplify the operation by storing the printing data in advance, reading out in due order, and continuously printing them. CONSTITUTION:Firstly, the proof value which is a total value of the data to be stored, and the registration data are input, and subsequently, when the collation key 12 is depressed, the collation result by the adder 3 is input to the collation key circuit 13. And unless the collation result sent to the circuit 13 is zero, the circuit 13 attaches an error display data to the first registration data taken out from the memory part 9, sends them into the buffer 14, and at the same time informs that there is an error in the data which have been registered in the batch. On the other hand, if the collation result in the circuit 13 is zero, the circuit sends the first registration data takenout from the memory part 9 into the buffer 14, and at the same time displays it on the display unit 20. In this way, the operation can be simplified by storing the printing data in advance, reading out in due order, and continuously printing them.

Description

[Detailed Description of the Invention] The present invention provides a method for preventing falsification of checks, bills of exchange, etc.
On receipts, etc., numbers, symbols, and
This invention relates to an electronic check writer that prints characters such as letters with unevenness so as to appear as if they were embossed.

A conventional check writer has a printing wheel for a plurality of digits, and has a structure in which printing is performed by manually setting the printing wheel for each digit for each piece of data. In the past, printing work was extremely complicated and printing could not be performed quickly.

In view of the above drawbacks, the present invention provides an electronic check writer that stores registered data in advance, reads the registered data sequentially each time a print start key is operated, and prints continuously in conjunction with the print start key operation. In addition, it is possible to confirm whether or not there is an error in the registered data based on the first operation of the print start key, and printing is performed sequentially based on the print start key operation after this confirmation. That is.

The present invention will be explained below based on the drawings. First, Fig. 1 shows a block circuit diagram of an electronic check writer as a reference example. This indicates a buffer for temporarily storing data input using the numeric keypad 1, and outputs the stored contents by pressing a minus registration key 4, which will be described later. 3 is an adder that sequentially adds data sent from buffer 2 and data sent from circuit 7, which will be described later; 4 is a minus registration key for registering the contents of buffer 2 as a negative value in adder 3; show. That is, this minus registration key 4 is used to store the proof value input using the numeric keypad 1 (for example, if the number of data to be stored is n, then that n
(the total value of the data) is registered as a negative value. To register the proof value as a negative value, press the minus registration key 4 after inputting the proof value using the numeric keypad 1, or press the numeric key 1
It is sufficient to input the n pieces of registration data one by one at , and press the minus registration key 4 for each input.

Reference numeral 5 indicates a plus registration key for making the input data from the numeric keypad 1 temporarily stored in the buffer 6 act as a plus value, and the contents of the buffer 6 are transferred to the circuit 7 when the key 5 is pressed. It is composed of

The circuit 7 already has an adder 3 which stores the proof value.
The buffer 6 is configured to send the contents of the buffer 6 to the input control circuit 8 of the memory section (RAM) 9. Reference numeral 10 indicates a counter that counts the number of presses of the plus registration key 5, and the contents of this counter 10 are sent to the address designation section 11 of the storage section 9.

That is, when the plus registration key 5 is pressed every time registration data is input using the numeric keypad 1, the registration data is sent as a plus value from the circuit 7 to the adder 3, where it is added to the previously input probe value, and at the same time, the input control It is sent to the storage section 9 via the circuit 8. Then, the contents of the counter 10 at this time are sequentially stored at addresses in the storage unit 9 designated by the addresses. In other words, if registration data is input in order by operating the numeric keypad 1 and the plus registration key 5, the data is sent to the adder 3 and checked against the proof value, and then the data is specified by the address designation section 11. storage section 9
They are stored in order in the addresses of .

12, the contents of the adder 3 (verification result) are sent to the circuit 13
When the content of the adder 3 is zero, the collation key circuit 13 for inputting the data into the adder 3 extracts the first registered data stored in the storage section 9 and sends it to the buffer 14 and the circuit 15. If the value is not zero, error display data is added to the contents of the adder 3 and sent to the circuit 15. Reference numeral 16 indicates a print start key that instructs printing of the displayed data. When this key 16 is pressed, a print command is sent to the printer 17, and the number of presses is recorded in the counter 1.
It is counted at 8.

The initial value of the counter 18 matches the address of the first data stored in the storage section 9.
Therefore, when the print start key 16 is pressed once, the contents of the counter 18 become the address of the second data stored in the storage section 9, and this address information is sent to the address specifying section 11. Then, the second data is output from the storage section 9 and sent to the buffer 14 via the output control circuit 19.
That is, by pressing the print start key 16, data can be output from the storage section 9 in order starting from the second data.

Note that when the print start key 16 is pressed, the data stored in the buffer 14 up to that point is sent to the printer 17 and printed.

The circuit 15 has input data from the numeric keypad 1,
The contents of the adder 3 when the minus registration key 4 is pressed, the data input using the numeric keypad 1 immediately before the plus registration key 5 is pressed, and the data output from the circuit 13 after the verification key 12 is pressed (1 stored in the storage section 9) It is configured to send the data output from the buffer 14 to the display device 20.

According to the above configuration, when the proof value is first input into the adder 3 using the numeric keypad 1 and the minus registration key 4, and then the registered data is input in order using the numeric keypad 1 and the plus registration key 5, each of the registered data is The signals are sent to the adder 3 and added to the proof value, and are also sent to the storage section 9 and stored in the order of input.

After inputting the proof value and the registered data in this manner, when the collation key 12 is pressed next, the collation result of the adder 3 (the collation result of the proof value and the registered data) is input to the circuit 13. and circuit 1
If the verification result sent to 3 is not zero, the circuit 13 attaches error display data to the first registered data retrieved from the storage section 9 and sends it to the buffer 14, and at the same time sends it to the circuit 15 and displays it on the display 20. Informs you that there is an error in the data that was registered in bulk.

On the other hand, if the verification result sent to the circuit 13 is zero, the circuit 13 sends the first registration data retrieved from the storage section 9 to the buffer 14 and at the same time sends it to the circuit 15 for display on the display 20.

Therefore, at this point, it can be determined that the verification result is correct, so when the print start key 16 is pressed next, a print command is output and the first registered data stored in the buffer 14 is transferred to the printer 1.
At the same time, the second registered data is taken out from the storage section 9, stored in the buffer 14, and displayed on the display 20. Therefore, by operating the print start key 16 while reconfirming the registered data displayed on the display 20, the registered data can be sequentially printed.

Next, the operating procedure will be briefly explained based on FIG. 2. In the part a in the figure, the proof value is registered as a negative value, and the proof value is displayed on the display. In part b, each piece of data is sequentially stored, and the data is sequentially added to the negative registered proof value. In part c, zero verification is performed between the proof value and the input registered data by pressing the verification key, and if the result is zero, it is assumed that there was no error during data registration, and the first registered data is displayed, and the result is If it is not zero, an error will be displayed as an error and the data will be registered again. In part d, display data when the verification result is zero is printed by operating the print start key. Thereafter, each time display data is printed using the print start key, the next data is displayed.

FIG. 3 shows an embodiment according to the present invention, which differs from the reference example shown in FIG. 1 in that the collation key is omitted and a control circuit 21 is added, and only the parts different from the reference example will be explained. . If the content of the counter 18 is "1", the control circuit 21 sends the signal α (corresponding to the collation key signal) to the circuit 13.
If the content is "2" or more, a signal β (print command signal) is output to the printer 17. Also, the initial value of the counter 18 is “0”
It is becoming. In this case, the initial value "0" of the counter 18 does not correspond to the address of the first data stored in the storage section 9, but the value "1" of the counter 18 corresponds to the address of the first data stored in the storage section 9. It has become something to do. Therefore, when the print start key is pressed for the first time, it performs the same function as the collation key, and from the second time onwards, it functions as the original print start key.

As described above in detail, according to the electronic check writer according to the present invention, if a plurality of registered data are stored in advance, they can be retrieved one after another and printed continuously. Therefore, it is possible to eliminate the inconvenience of having to perform printing every time one piece of data is set, which is the case in the prior art.

Also, before starting continuous printing, it is possible to check whether there is an error in the data registered all at once.

Furthermore, after printing of one data is completed, the next data is displayed, so that continuous printing can be performed while reconfirming each registered data.

Furthermore, since the print start key has the function of a collation key, operation is easy.
