Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing device for a cash register that prints the preset conditions of each product category line by line so that the preset conditions can be easily read.

Conventionally, conditions such as unit price, taxation, discount, single item sales, etc. are set in advance for each product category, and registration is performed using the set conditions. , each condition had to be checked, and an operator who did not know the contents could not easily check the contents, which caused problems in use.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a printing device for an electronic cash register that allows easy checking of preset conditions.

FIG. 1 is a circuit diagram showing an embodiment of the present invention. In the figure, 1 is the keyboard, with number keys and 1
- 8 product department keys, cash sales, rental sales,
It has transaction-specific keys such as coupon, payment, deposit, and total, and provides key signals to the control circuit 2.
The control circuit 2 reads the program from the program storage circuit 3 via the address register 31 based on the key signal, and executes various registration processes. For example, addition and subtraction between the content entered in the first register 41 from the keyboard 1 and the content read out to the second register 42 is performed.

The first and second registers 41 and 42 are, for example, 1 digit 4.
A register that stores numerical values in an 8-digit bit format.
The assignment or transfer takes place via the gates G ₁ , G ₂ , G ₃ . The contents of the second register 42 are stored in the matching circuit 51.
and is converted into a print signal.

The coincidence circuit 51 is given a signal from a detector 53 that detects the rotational position of the print drum 52, sends a signal corresponding to the digit to be printed to the printer register 54, and drives the hammer 56 via the drive circuit 55. , print. For example, when "123" is stored in the second register 42, when the rotational position of the print drum 52 is 1, the coincidence circuit 51 sends a digit information signal corresponding to "1" of "123" to the printer register 54. Then, "1" is printed in the corresponding digit via the drive circuit 55. followed by “2”
“3” is printed according to the rotational position of the print drum 52.

Reference numeral 6 denotes a data storage circuit, which includes amount storage units 31 to 68 and preset storage units 71 to 78 corresponding to the first to eighth product categories, and also stores transaction specific storage units (not shown). Ru. The amount storage units 61 to 68 have, for example, 8 digits with 4 bits per digit, and each department and each digit are sent to the second register ₄₂ via gate G3 by a department address register 81 and a digit address register 82. and gate G ₄
The contents of the second register 42 are written through. The preset memories 71 to 78 are, for example, 1 digit.
It consists of four bits, and stores conditions such as unit price, taxation, discount, and whether or not it is sold separately, and is read out for each department and each bit by the department address register 81 and bit address register 83. , a determiner 91 determines whether each bit has information or not, that is, whether it is "1" or "0". The judgment output is given to the control circuit 2 and used in the control circuit 2, and then a print digit information signal corresponding to the print position on the print drum 52 is sent from the signal generator 92 to the gate.
G ₃ and written to the second register 42 .

FIG. 2 is a diagram showing the type pattern of the printing drum 52, in which 13 rows of type 0 to 12 and 8 columns of 1 to 8 are used. Mainly, numbers 0 to 9, department indicators 1 to 8, and printed characters for displaying transactions such as cash Ca lending and selling Ch are provided. On the 12th line, the unit price (@),
There is a line of type that indicates discount (N), single item sale (SI), and taxation (Ta). Therefore, when printing the unit price (@), write the hexadecimal number "1100" indicating "12" 2 or 3 from the bottom of the second register 42.
It is stored in the digit and printed by sending a signal to the matching circuit 51.

Next, the operation will be explained. In the case of normal registration, the number entered from the keyboard 1 is first given to the first register 41. After that, the department address register 81 and digit address register 8 are entered by the department key.
2 is driven by the control circuit 2, and the amount memory 6
The corresponding departments from 1 to 68 are selected and stored in the second register 4.
2. and the first and second registers 4
The contents of numbers 1 and 42 are introduced into the control circuit 2, added, and the sum is written into the second register 42, and the value is selected and written into the corresponding department of the amount storage units 61 to 68 in the same manner as the above reading.

The above addition result or set value is stored in the second register 42.
The data is transferred to the printer and sent to the printing machine via the matching circuit 51 for printing.

Preset memories 71 to 7 of data storage circuit 6
8, first, a preset signal from the keyboard 1 is given to the control circuit 2, and the conditions to be preset are set in advance, for example, unit price (@, discount (N), single item sale (SI), taxation (Ta)). The assigned number is entered from the keyboard 1 and temporarily stored in the control circuit 2.Then, by pressing the product department key, the control circuit 2 drives the department address register 81 and the bit address register 83, and presets. A condition "1" is stored in the corresponding bit position of the corresponding department in the memory devices 71 to 78. For example, unit price (@), discount (N), single item sale (SI), taxation (Ta)
If the bit positions are determined from the right in the order of
When the unit price (@) and single item sale (SI) conditions are set, "1010" is stored.

If you want to check the content after it has been preset by the above operation, press the check key.
In response to the check key, the control circuit 2 operates as shown in the flowchart of FIG. First, the department address register 81 is set to "1" to designate the first department, and the bit address register 83 is set to "1" to designate the first department.
The third digit is set to "1" for bit designation, and is the designated digit indicating which digit of the second register 42 the signal generator 92 should output. Data storage circuit 6 is read under this set condition, and the contents of the first bit of preset storage 71 are read to determiner 91. The determiner 91 transmits the output to the control circuit 2 when the output is "1", and the control circuit 2
In the next operation, the signal generator 92 is driven, and the third digit from the bottom of the second register 42 is filled with "12", that is, the hexadecimal value of the data indicating the 12th line of the type drum 52. Write “1100”. If the content read and stored in the determiner 91 is "0", the above operation is not performed and the second register 42 maintains its content.

Next, "1" is added to the bit address register 83, and "1" is also added to the specified digit of the signal generator 92 in preparation for reading the next bit. Since the bit reading is not completed, the above operation is repeated again to read out the contents of 4 bits, and based on the judgment, the digit information signal to be printed is at the 0th line, which indicates the position of the type drum 52 where the printed type of the first category is located. In order to designate the second digit, data "0" is written to the second digit of the second register 42 (see FIG. 2). Therefore, the digit signal is written into the second to sixth digits of the second register 42. Since we do not want to print the other digits, we write all "1"s in the second register 42 in advance, and then write digit signals to the second to sixth digits, so that the other digits remain "1". remain. When the above content is sent to the printer register 54 via the matching circuit 51, "1" is printed in the second digit, and the third to sixth digits are unit price (@), discount (N), single item sale ( It is printed according to the conditions of SI) and taxation (Ta), and since the other digits are "1111" or "15", there is no type in the corresponding line in Figure 2 and it is not printed.
Therefore, for example, if the conditions of unit price (@) and single item sale (SI) are set in the first department and "1010" is stored in the preset memory 71, pressing the check key will change "SI@1". Because it is printed,
It is easy to see that the unit price (@) and single item sales (SI) conditions are preset in the first division.

Thereafter, "1" is added to the department address register 81, and the contents of the preset memory 72 are written in the 3rd to 6th digits of the second register 42 in the same manner as described above. The data "1" in the first line indicating the position of the print character on which the department is printed is written to the second digit of the second register 42 and printed. Similarly, the process ends after printing up to the 8th category.

By the above operation, the preset contents of the first to eighth product categories are printed line by line, so that they can be easily confirmed.

As described above, the present invention includes a circuit that stores product category conditions such as unit price and taxation in advance, a circuit that reads out the conditions from the memory circuit and judges the conditions, and a line of printed digit information based on the output of the judgment circuit. The preset machine consists of a circuit that generates a signal, and a printing machine that prints the preset conditions on one line, and has a type drum with one line of dedicated type that prints the conditions for each product category based on the signal from the generation circuit. You can check the conditions at a glance and check the contents quickly.
