`
`DATA PRINT CONTROL IN AN ELECTRONIC
`CASH REGISTER
`
`BACKGROUND AND SUMMARY OF THE
`INVENTION
`
`The present invention relates to an electronic cash
`register and, more particularly, to a print control system
`in an electronic cash register.
`The electronic cash register is widely used in various
`stores and markets. The electronic cash register in-
`cludes a printer system for printing out a preselected
`data on a receipt bill or a journal paper. There is a
`possibility that the data which should be printed out
`varies in accordance with the scale of the store and the
`type of business. To satisfy this requirement, the elec-
`tronic cash register is sometimes designed for a specific
`store. This precludes the mass production of the elec-
`tronic cash register.
`Accordingly, an object of the present invention is to
`provide an electronic cash register suited for the versa-
`tile use.

`
`Another object of the present invention is to provide
`a novel print control system in an electronic cash regis-
`ter.
`
`25
`
`2
`print control system of the present invention will be
`described in conjunction with a preset mode and a nor-
`mal registration mode.
`‘
`
`(PRESET MODE)
`
`A mode selection key 2 included in function keys 1 is
`provided for implementing a preset mode. A preset
`mode signal derived from the mode selection key 2 is
`applied to an AND gate 3 to place the AND gate 3 in an
`operative condition, and is also applied to the central
`processor unit 5 through a key determination circuit 4
`to indicate that the electronic cash register is in the
`preset mode. In response to the preset mode signal de-
`rived from the mode selection key 2, the central proces-
`sor unit 5 selects a preset routine stored in a read only
`memory 6. The read only memory 6 stores various
`programs related to transaction processings.
`The main memory 11 includes a number of memory
`sections for memorizing transaction information. As
`shown in the following TABLE 1, date information,
`receipt serial number, machine number, clerk code in-
`formation and time information are stored in addresses
`50 through 55 of the main memory 11 in the binary code
`notation.

`The machine number is a fixed number assigned to

`circuit 18 is provided for updating the date information
`stored in the address 50 through a date buffer 19, and
`the current time information stored in the address 55
`through a time buffer 20. A counter 21 is associated
`with a printer system 17 for incrementing the receipt
`serial number stored in the address 51 upon every issue
`of the receipt bill. A clerk code key 22 is included in the
`function keys 1 for introducing the clerk code number
`into the address 53 through the use of numeral keys 7.
`The last it bit in the addresses 50 through 55 is as-
`signed to store a binary code signal “I" or “0" which
`indicates whether the corresponding data should be
`printed out on the receipt bill or the journal paper, or
`the corresponding data should not be printed out. The
`following TABLE II shows an example of the memory
`condition in the addresses 50 through 55.

`Other objects and further scope of applicability of the
`present invention will become apparent from the de-
`tailed description given hereinafter. It should be under-
`stood, however, that the detailed description and spe
`cific examples, while indicating preferred embodiments
`of the invention, are given by way of illustration only,
`since various changes and modifications within the
`spirit and scope of the invention will become apparent
`to those skilled in the art from this detailed description.
`To achieve the above objects, pursuant to an embodi-
`ment of the present invention, a data print preset system
`is provided for presetting a print condition of prese-
`lected data information. If the preselected data is de-
`sired not to be printed out on a receipt bill or a journal
`paper, a print inhibition signal is introduced through a
`print inhibition preset key and stored in a memory at a
`position corresponding to the preselected data. In a
`normal registration operation mode,
`the preselected
`data followed by the print inhibition signal
`is never
`printed out on the receipt bill or the journal paper.
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`The present invention will be better understood from
`the detailed description given hereinbelow and the ac-
`companying drawing which is given by way of illustra—
`tion only, and thus is not Iimitative of the present inven-
`tion and wherein:
`
`The single FIGURE of the drawing is a block dia-
`gram of an embodiment of a data print control system in
`an electronic cash register of the present invention.
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`A data print control system in an electronic cash
`register of the present invention comprises a data print
`preset system for presetting the print condition, and a
`detection circuit for determining the print condition in
`a normal registration operation mode. More specifi-
`cally, the data print control system comprises a central
`processor unit 5, a main memory 11, a print inhibition
`preset key 12 for presetting the print condition, a print
`inhibition signal generator 13, and a print inhibition
`signal detection circuit 16. Detailed construction of the
`
`65
`
`The memory condition shown in the above TABLE
`II indicates that the date information, the receipt serial
`number and the time information should be printed out.
`and the machine number and the clerk code information
`are not required to be printed out. To preset the above
`
`3
`
`

`

`‘
`
`3
`discussed print condition, the address corresponding to
`the information which is not required to be printed out
`is selected through the use of the numeral keys 7. Nu-
`merals keys [I] and [I are successively actuated to
`introduce numeral
`information “52” into the central
`processor unit 5 through a key encoder 8. Then, a print
`selection key 9 included in the function keys 1 is actu-
`ated to instruct the central processor unit 6, via the key
`determination circuit 4, that the numeral information is
`flO
`the address information In response to the actuation o
`the print selection key 9, the central processor unit 5
`selects, in accordance with the program control stored
`in the read only memory 6, a section d of the address 52
`in the main memory 11 via an address counter 10.
`Thereafter, the print inhibition preset key 12 included in
`the function keys 1 is actuated to enable the print inhibi-
`tion signal generator 13 via the AND gate 3. The print
`inhibition signal generator 13 develops a high level
`signal “1" which is introduced into and stored in the
`section d of the address 52 in the main memory 11 via
`the central processor unit 5 and an input/output circuit
`14. In this way, the print control system is preset not to
`print out the machine number stored in the address 52.
`The section d of the address 53 in the main memory
`11 is also selected in the same manner as discussed
`above through the use of the numeral keys 7 and the
`print selection key 9. The print inhibition preset key 12
`is actuated to introduce the information “1” into the
`section d of the address 53 in the main memory 11,
`whereby the print control system is preset not to print
`out the clerk code information stored in the address 53.

`
`25
`

`
`‘(NORMAL REGISTRATION MODE)
`'
`The mode selection key 2 included in the function
`keys 1 is also provided to implement a normal registra-
`tion mode. When a specific transaction occurs, a unit
`‘price value and number or quantity information are
`introduced from the numeral keys 7 into the central
`processor unit 5 through the key encoder 8. A desired
`department key included in the function keys 1 is actu-
`ated to indicate the related department. The department
`signal is introduced into the central processor unit 5
`through the key determination circuit 4. The central
`processor unit 5 functions to select a suitable address in
`the main memory 11 through the address counter 10, in
`accordance with the department signal derived from
`the key determination circuit 4, whereby the transaction
`data is introduced into a section b of the selected ad-
`dress in the main memory 11 through the input/output
`circuit 14. These operations are controlled by a pro-
`gram data stored in the read only memory 6.
`During these operations, the introduced transaction
`information is displayed on a display unit 15. And, a
`preselected data is printed out on a receipt bill or on a
`journal paper by the printer system 17. More specifi-
`cally, regarding the information stored in the addresses
`50 through 55, the print inhibition signal detection cir-
`cuit 16 monitors the last bit of the addresses 50 through
`55. If the information “I" is stored at the last bit, the
`print inhibition signal detection circuit 16 functions not
`to transfer the data stored at the corresponding address
`toward the printer system 17. Accordingly,
`in the
`above-mentioned example, the machine number and the
`clerk Code information are not printed out on the re-
`ceipt bill or the journal paper. Remaining data are

`the‘printer system 17.
`The invention being thus described, it will be obvious
`that the same may be varied in many ways. Such varia-
`tions are not to be regarded as a departure from the
`spirit and scope of the invention, and all such modifica-
`tions are intended to be included within the scope of the
