Abstract
ABSTRACT OF THE DISCLOSURE
An electronic cash register comprises a read only memory, a central processor unit, entry and function keys, a memory including an entry memory storing input data from the entry keys and first and second data memories storing respectively first and second data, a double function key for transferring first data to the first data memory and second data to the second data memory, and printing means for printing data, price total and the first and second data. The memory comprises a first flag memory storing a "1" when the entry memory stores the first data and a second flag memory which stores a binary bit "1" when first data is transferred from the entry memory to the first data memory.
When the double function key is operated while first data is stored in the entry memory and "1" is stored only in the first flag memory, the first data is transferred to the first data memory and the second flag memory now stores a "1". The entry and first flag memories are then cleared.
Thereafter, when the double function key is operated while second data is stored in the entry memory and a "1" is stored in both the first and second flag memories, second data is transferred to the second data memory. If the transferred second data is incorrect, the entry keys are operated to store a new correct second data into the entry memory. Then, the double function key is operated to transfer the new second data to the second data memory.
Thereafter, the second flag memory is cleared to permit storing input data in the entry memory which represents a merchandise price. First the first date (for example, date data) is stored into the first data memory (for example, date data memory), and the second data (for example, regis-tered number data) into the register number memory. If a wrong register number is stored into the register number memory, it is only required to replace the wrong register number by the correct one without replacing a correct date with the name correct date.

An electronic cash register shown in Figure 1 comprises a casing 10 containing the electric circuit shown in Figure
3. A keyboard 11 is mounted on the front panel of the casing and including various types of keys shown in Figure 2. More particulary, there are provided an entry key gxoup 12 for setting the price and number of the merchandise sold, a function key group 13 fox operating, for example, ad-dition, subtraction and multiplication operations of the . input data, a clerk key group 14 for setting the operator of : the register in the form of a code A, B, C, or D, for :

The entry key group 12 includes keys for ".", "00" and "0" to "9", for example. The function key group 13 contains for example a clear key "C" (13-1), a multiplication key "X'(13-2), a void key "VOID" (13-3), a no sale key "NS" (13-4), a return merchandise key "RTN" (13-5), percent keys "%-" (13-6) and "~" (13-7), a number key "#" (13-8), a received on account key "R/A" (13-9), a subtract key "(-)" (13-10), a paid out key "PO (13-11), a sub-total key "ST" (13-12), a credit sales total key "CRT" (13-13) and a double function key "AT/TL" (13-14) having functions of both of amount tendered key "AT" and a cash total key "TL". Further, the casing 10 is provided with a display section 20 for displaying sub-total (ST), total (TL), register number, void, etc., a roll mounting section 22 for mounting a supply roll 21 of the receipt sheet and the journal paper, a receipt taking out portion 23, a window for inspecting the content of the record printed on the journal paper, a memo paper holder 25 for holding a memo paper or the like by a permanent magnet, ~-not shown, a drawer 26 for accommodating and taking out cash, and a main key switch 27. The main key switch 27 is -operated by a key carried by the operator of a given regis-ter or a supervisor for applying to a central processor unit (CPU) to be described later a command signal for causing it to perform such operations as "register", "inspection" and "clear". The term "register" is used herein to express a ., ; series of operations of storing the input data regarding the price of the merchandise in a memory device of the cash ~" .

108184!7 register, totalizing the inputs, and printing respective input data and the total thereof on the receipt sheet and the journal paper. The term "inspection" means the opera-tion of checking the total price of the merchandises sold and the total number of the merchandises sold which have been stored in the memory by printing these data on the journal paper. The term "clear" is used to mean an opera-tion for clearing the content of the memory device when a given operation has been completed while at the same time for printing on the journal paper the total price and the total number of the merchandises sold which are stored in the memory device.
As shown in Figure 3, the movable contact 27a of a main key switch 27 is thrown to either one of stationary contacts lS 27b-27e. When contact 27b is closed the operation is "OFF"
and when contact 27c is closed the operation is "register".
When contacts 27d and 27e are closed the operations are "inspection" and "clear" respectively. Assume now that contact 27c, that is the "register" terminal is closed, a circuit 28 for judging and processing a signal from the main key 27 transmits an order to a central processor unit 29 for commanding it to perform an operation necessary for regis-tration. The output from the key board 11 is applied to a circuit 30 for judging and processing the output whereby the circuit 30 sends a signal corresponding to the operation of the key of the key board to the central processor unit 29.
The output of the central processor uni* 29 is applied to a memory device 32 via an interface 31. The data stored in the memory device 32 and to be printed on the receipt sheet and the journal paper are sent to a data selector 33 via the ~, ~

interface 31. The output data from the data selector 33 are stored in a print buffer register 34. A printer 35 is controlled by a printer driver 36. The printer driver 36 is controlled by the central processor unit 29 via conductor 37 for printing the data from the print buffer register 34 on a printing paper, not shown. A bit pulse generator 38 gene-rates a clock signal under the control of the central , processor unit 29 for writing the input data with a prescri-bed timing in a totalizer to be described later. A circuit 29 for producing a processing instruction signal after recovering a source of supply is connected to the memory device 32 via the interface 31 and the instruction signal produced by the circuit 29 is applied to a read only memory circuit 40 which is coupled with the central processor unit 29 and storing therein a fixed program.
The memory device 32 comprises an entry memory (entry key input ;.

10818~7 data memory) 41 for temporarily storing the entry produced by the operation of the entry key group 12 of the key board, an entry key flag memory (flag memory for entry key) 42, a flag memory 43 for the date/register number set key 18, a date memory 44, a register number memory 45 and a totalizer 46. The totalizer may be constructed such that it can totalize the input data according to the types of the merchandise, customers, register operators or supervisors, respectively, and may be constituted by a memory circuit utilizing complementary metal oxide semiconductors (CMOS).
Memories 41, 42, 43, 44 and 45 can also be constituted by CMOS. These memories may be provided with means which prevents erasure of the contents thereof at the time of the interruption of the source of supply, for example a transfer ! 15 switch which connects a battery to the memories upon interr-uption of the power supply, or may comprise non-volatile memories. The entry key flag memory 42 and the date/regis-ter number set key flag memory 43 may be constructed as units independent of other memories.
2 The invention is characterized in that there are provided the entry key flag memory 42 and the date/register number set key flag memory 43, and that the flag memorising states of these flag memories are interlocked with the operations of the entry keys 12 and the date/register number set key 18 thereby enabling ready setting of the date and the register number in the date memory 44 and the register number memory 45 respectively. The entry key flag memory 42 is composed of a bistable memory, for example, which takes first or second output state and which stores binary "1"
;i 30 (first output state, for example) when the entry data are ~ ~7~

stored in the entry memory 41. Thus, the flag memory 42 stores a binary "1" when a date to be set in the date memory 44 is stored in the entry memory 41. The date/register number setting flag memory 43 is constructed to store binary "1" when the date data that has been stored in the entry memory 41 is written in the data memory 44. The relation-ship among the flag memories, the operations of respective keys and the setting of the date and the register number is as follows.
1 When the entry key group 12 is operated to set the date the key board input judging and processing circuit 30 ; sends the content of the entry to the central processor unit 29, which in turn causes to store the content of the entry in the entry memory 41 of the memory device via the in-terface 31. When the content of the entry is stored in the `~ memory 41 the entry key flag memory 42 stores binary "1".
When the date/register number set key 18 is operated under these conditions, the key board input judging and processing circuit 30 transmits the content of the key 18 to the central processing unit 29. Then, the unit 29 firstly reads the content of the entry key flag memory 42, and when this . memory 42 is storing "1" at this time, then reads the content of the date/register number set key flag memory 43.
~ If the memory 43 is not storing "1" at this time, the date ;', 25 data which has been stored in the entry memory 41 is set in the date memory 44. Upon completion of the date setting the ~j central processor unit 29 causes to store "1" (first output -~ state, for example) in the date/register number set flag . .
. memory 43. Upon setting of ~he date in the date memory 44 the date data in the entry memory 41 and the "1" in the ~ entry key flag memory 42 are cleared. Such clearing ;, , ~ 8-., .~ .

``- 108~84~7 may be performed at the first step of the operation of the next entry key.
When the register number is set by the operation of the entry key group 12, the key board input judging and processing circuit 30 transmits the content of the operation ; of the key to the central processor unit 29, thereby causing ; to store the entry content of the register number in the entry memory 41 via the interface 31. When the entry memory 41 stores the register number the entry key flag memory 42 stores again "1". At this stage, that is under the con-dition wherein the flag memories 42 and 43 respectively storing "1", when the set key 18 is operated, the key board input judging and processing circuit 30 transmits the ' content of the operation of the key 18 to the central ; 15 processor unit 29. Then, this unit reads the content of the entry key flag memory 42 and if this memory is storing "1", the unit reads the content of the date/register number set key ,:

flag memory 43. At this time, when this memory 43 is storing "1" the register number stored in the entry memory 41 is written into the register number memory 45. upon setting the register number into the memory 45, the contents of the entry memory and the entry key flag memory 42 are cleared. The clearing of the memories 41 and 42 may be made at the first stage of the entry operation which is performed after setting the date and register number. In this manner, the date and the register number are set in the date memory 44 and the register number memory 45, respectively.
When the register number is erroneously set at the time of setting the date and the register number, the entry key group 12 is operated to set a correct register number by the operations of the entry key group 12 and the date/register number set key 18. At this time, as "1" is stored in the date/register number set key flag memory 43 when the date is set in the date memory 44, the correct register number newly stored in the entry memory 41 is set in the register number memory 45. Thus, the erroneously set register number is automatically cleared when the correct register number is set again. In the prior art cash register, however, in order to set again the register number, it is necessary to reset the date again and then set the correct register number. In this invention, after setting the date and the --register number, when the operator of the cash register !, comes to aware that the set data of the date is not correct, ~ or where it is necessary to set a new date the clear key 13-~j . .
1, for example, is operated to clear "1" in the date/regis-ter number set key flag memory 43. Then the operator operates the entry key 12 and the double function key 18 for _g_ . " .

setting the correct date or the new date.
When the correct data and register number have been set the second flag memory continues to store "1" until clear key 13-1 is operated. The "1" stored in the date/regis-ter number set key flag memory 43 can be cleared by the operation of the clear key 13-1 or the no sale key 13-4.
Further the "1" can also be cleared by the first registra-tion data input immediately succeeding the settings of the date and the register number, that is by the first operation of the entry key 12 and the operation of the department key 15 succeeding thereto.
Following the setting of the date and the register number, various data regarding the sales are registered.
For example, the prices of the merchandises sold, and the departments thereof are set by the operation of the entry key group 12 and the department key group 15. Then these data are written in the totalizer 46. The data written in the totalizer 46, the date written in the date memory 44 and the register number written in the register number memory 45 are applied to the printing buffer register 34 via the interface 31 and the data selector 33. These data are printed on a receipt sheet and the journal paper by the ~ printer 35 driven by the printer drive circuit 36 which is `~ controlled by the central processor circuit 29.
To perform the "inspection" operation, the contact 27d of the main key 27 is closed and then the AT/TL key 13-14 is operated for sequentially reading out the data which have been stored in the totalizer 46 from the previous clear operation prior to this time. The date in the date memory 44 and the register number in the register number memory 45 are also read out and printed together with the data read .

out from the totalizer 46 on the journal paper. The content of the totalizer is preserved even when these data are read during the "inspection" operation. To perform the "clear"
operation, the stationary contact 27e of the main key 27 is closed to operate the AT/TL key 13-14. At this time, the content which has been stored in the totalizer 46 between the previous "clear" operation and the closure of the contact 27e is read out together with the date and the register number stored in the date memory 44 and the regis-ter number memory 45, respectively. These read out data are also printed on the journal paper in the same manner as in the "inspection" operation. However, the contents of the totalizer and various memories 41, 42, 43, 44 and 45 are also cleared.
Where the first and second data are not required to be changed during a number of registration operations, it is possible to store the first data in the date memory 44 instead of a date and to store the second data in the register number memory 45 instead of a register number.
Turning now to the flow chart shown in Figure 4, how and in what sequence the necessary data are stored or set in the memories 41, 44 and 45, and how "1" is stored in the flag memories 42 and 43 in accordance with the operations of the entry key 12 and the double function key 18 will be described hereunder. (A) When the operation of the key is requested, (B) the operation or not operation of the entry keys is judged. (C) When the entry keys are operated the entry data are stored in the entry memory 41. (D) When the entry data (in this case, the first data) is stored in the entry memory 41, the entry key flag memory 4~ store~ "1".

When "1" has not been stored (NO), (H) the content or the date in the entry memory 41 is set in the date memory 44.
(J) When the date is set in the memory 44, the date/register number set key flag memory 43 stores "1".

The term "inspection" means the opera-tion of checking the total price of the merchandises sold and the total number of the merchandises sold which have been stored in the memory by printing these data on the journal paper. The term "clear" is used to mean an opera-tion for clearing the content of the memory device when a given operation has been completed while at the same time for printing on the journal paper the total price and the total number of the merchandises sold which are stored in the memory device.
As shown in Figure 3, the movable contact 27a of a main key switch 27 is thrown to either one of stationary contacts lS 27b-27e. When contact 27b is closed the operation is "OFF"
and when contact 27c is closed the operation is "register".
When contacts 27d and 27e are closed the operations are "inspection" and "clear" respectively. Assume now that contact 27c, that is the "register" terminal is closed, a circuit 28 for judging and processing a signal from the main key 27 transmits an order to a central processor unit 29 for commanding it to perform an operation necessary for regis-tration. The output from the key board 11 is applied to a circuit 30 for judging and processing the output whereby the circuit 30 sends a signal corresponding to the operation of the key of the key board to the central processor unit 29.
The output of the central processor uni* 29 is applied to a memory device 32 via an interface 31. The data stored in the memory device 32 and to be printed on the receipt sheet and the journal paper are sent to a data selector 33 via the ~, ~

interface 31. The output data from the data selector 33 are stored in a print buffer register 34. A printer 35 is controlled by a printer driver 36. The printer driver 36 is controlled by the central processor unit 29 via conductor 37 for printing the data from the print buffer register 34 on a printing paper, not shown. A bit pulse generator 38 gene-rates a clock signal under the control of the central , processor unit 29 for writing the input data with a prescri-bed timing in a totalizer to be described later. A circuit 29 for producing a processing instruction signal after recovering a source of supply is connected to the memory device 32 via the interface 31 and the instruction signal produced by the circuit 29 is applied to a read only memory circuit 40 which is coupled with the central processor unit 29 and storing therein a fixed program.
The memory device 32 comprises an entry memory (entry key input ;.

10818~7 data memory) 41 for temporarily storing the entry produced by the operation of the entry key group 12 of the key board, an entry key flag memory (flag memory for entry key) 42, a flag memory 43 for the date/register number set key 18, a date memory 44, a register number memory 45 and a totalizer 46. The totalizer may be constructed such that it can totalize the input data according to the types of the merchandise, customers, register operators or supervisors, respectively, and may be constituted by a memory circuit utilizing complementary metal oxide semiconductors (CMOS).
Memories 41, 42, 43, 44 and 45 can also be constituted by CMOS. These memories may be provided with means which prevents erasure of the contents thereof at the time of the interruption of the source of supply, for example a transfer ! 15 switch which connects a battery to the memories upon interr-uption of the power supply, or may comprise non-volatile memories. The entry key flag memory 42 and the date/regis-ter number set key flag memory 43 may be constructed as units independent of other memories.
2 The invention is characterized in that there are provided the entry key flag memory 42 and the date/register number set key flag memory 43, and that the flag memorising states of these flag memories are interlocked with the operations of the entry keys 12 and the date/register number set key 18 thereby enabling ready setting of the date and the register number in the date memory 44 and the register number memory 45 respectively. The entry key flag memory 42 is composed of a bistable memory, for example, which takes first or second output state and which stores binary "1"
;i 30 (first output state, for example) when the entry data are ~ ~7~

stored in the entry memory 41. Thus, the flag memory 42 stores a binary "1" when a date to be set in the date memory 44 is stored in the entry memory 41. The date/register number setting flag memory 43 is constructed to store binary "1" when the date data that has been stored in the entry memory 41 is written in the data memory 44. The relation-ship among the flag memories, the operations of respective keys and the setting of the date and the register number is as follows.
1 When the entry key group 12 is operated to set the date the key board input judging and processing circuit 30 ; sends the content of the entry to the central processor unit 29, which in turn causes to store the content of the entry in the entry memory 41 of the memory device via the in-terface 31. When the content of the entry is stored in the `~ memory 41 the entry key flag memory 42 stores binary "1".
When the date/register number set key 18 is operated under these conditions, the key board input judging and processing circuit 30 transmits the content of the key 18 to the central processing unit 29. Then, the unit 29 firstly reads the content of the entry key flag memory 42, and when this . memory 42 is storing "1" at this time, then reads the content of the date/register number set key flag memory 43.
~ If the memory 43 is not storing "1" at this time, the date ;', 25 data which has been stored in the entry memory 41 is set in the date memory 44. Upon completion of the date setting the ~j central processor unit 29 causes to store "1" (first output -~ state, for example) in the date/register number set flag . .
. memory 43. Upon setting of ~he date in the date memory 44 the date data in the entry memory 41 and the "1" in the ~ entry key flag memory 42 are cleared. Such clearing ;, , ~ 8-., .~ .

``- 108~84~7 may be performed at the first step of the operation of the next entry key.
When the register number is set by the operation of the entry key group 12, the key board input judging and processing circuit 30 transmits the content of the operation ; of the key to the central processor unit 29, thereby causing ; to store the entry content of the register number in the entry memory 41 via the interface 31. When the entry memory 41 stores the register number the entry key flag memory 42 stores again "1". At this stage, that is under the con-dition wherein the flag memories 42 and 43 respectively storing "1", when the set key 18 is operated, the key board input judging and processing circuit 30 transmits the ' content of the operation of the key 18 to the central ; 15 processor unit 29. Then, this unit reads the content of the entry key flag memory 42 and if this memory is storing "1", the unit reads the content of the date/register number set key ,:

flag memory 43. At this time, when this memory 43 is storing "1" the register number stored in the entry memory 41 is written into the register number memory 45. upon setting the register number into the memory 45, the contents of the entry memory and the entry key flag memory 42 are cleared. The clearing of the memories 41 and 42 may be made at the first stage of the entry operation which is performed after setting the date and register number. In this manner, the date and the register number are set in the date memory 44 and the register number memory 45, respectively.
When the register number is erroneously set at the time of setting the date and the register number, the entry key group 12 is operated to set a correct register number by the operations of the entry key group 12 and the date/register number set key 18. At this time, as "1" is stored in the date/register number set key flag memory 43 when the date is set in the date memory 44, the correct register number newly stored in the entry memory 41 is set in the register number memory 45. Thus, the erroneously set register number is automatically cleared when the correct register number is set again. In the prior art cash register, however, in order to set again the register number, it is necessary to reset the date again and then set the correct register number. In this invention, after setting the date and the --register number, when the operator of the cash register !, comes to aware that the set data of the date is not correct, ~ or where it is necessary to set a new date the clear key 13-~j . .
1, for example, is operated to clear "1" in the date/regis-ter number set key flag memory 43. Then the operator operates the entry key 12 and the double function key 18 for _g_ . " .

setting the correct date or the new date.
When the correct data and register number have been set the second flag memory continues to store "1" until clear key 13-1 is operated. The "1" stored in the date/regis-ter number set key flag memory 43 can be cleared by the operation of the clear key 13-1 or the no sale key 13-4.
Further the "1" can also be cleared by the first registra-tion data input immediately succeeding the settings of the date and the register number, that is by the first operation of the entry key 12 and the operation of the department key 15 succeeding thereto.
Following the setting of the date and the register number, various data regarding the sales are registered.
For example, the prices of the merchandises sold, and the departments thereof are set by the operation of the entry key group 12 and the department key group 15. Then these data are written in the totalizer 46. The data written in the totalizer 46, the date written in the date memory 44 and the register number written in the register number memory 45 are applied to the printing buffer register 34 via the interface 31 and the data selector 33. These data are printed on a receipt sheet and the journal paper by the ~ printer 35 driven by the printer drive circuit 36 which is `~ controlled by the central processor circuit 29.
To perform the "inspection" operation, the contact 27d of the main key 27 is closed and then the AT/TL key 13-14 is operated for sequentially reading out the data which have been stored in the totalizer 46 from the previous clear operation prior to this time. The date in the date memory 44 and the register number in the register number memory 45 are also read out and printed together with the data read .

out from the totalizer 46 on the journal paper. The content of the totalizer is preserved even when these data are read during the "inspection" operation. To perform the "clear"
operation, the stationary contact 27e of the main key 27 is closed to operate the AT/TL key 13-14. At this time, the content which has been stored in the totalizer 46 between the previous "clear" operation and the closure of the contact 27e is read out together with the date and the register number stored in the date memory 44 and the regis-ter number memory 45, respectively. These read out data are also printed on the journal paper in the same manner as in the "inspection" operation. However, the contents of the totalizer and various memories 41, 42, 43, 44 and 45 are also cleared.
Where the first and second data are not required to be changed during a number of registration operations, it is possible to store the first data in the date memory 44 instead of a date and to store the second data in the register number memory 45 instead of a register number.
Turning now to the flow chart shown in Figure 4, how and in what sequence the necessary data are stored or set in the memories 41, 44 and 45, and how "1" is stored in the flag memories 42 and 43 in accordance with the operations of the entry key 12 and the double function key 18 will be described hereunder. (A) When the operation of the key is requested, (B) the operation or not operation of the entry keys is judged. (C) When the entry keys are operated the entry data are stored in the entry memory 41. (D) When the entry data (in this case, the first data) is stored in the entry memory 41, the entry key flag memory 4~ store~ "1".
