Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is applicable to electronic cash registers, POS registers,
The present invention relates to a sales data processing device such as an electronic scale for face-to-face sales, and particularly relates to a sales data processing device configured such that a keyboard pattern, which is the arrangement of keys on a keyboard, can be changed.

"Prior Art" In conventional electronic cash registers, keys are arranged in a matrix, and various functions are fixedly assigned to each key.

However, such an electronic camper can be very inconvenient to operate depending on the working environment and the operator. For example, there are right-handed and left-handed operators, and in a fixed key layout, the key functions are determined to be convenient for right-handed operators, but are extremely inconvenient for left-handed operators. Met. A left-handed operator is forced to endure inconvenience during operation, which has the disadvantage of reducing work efficiency.

Furthermore, with a fixed key arrangement, the keyboard pattern is uniform and there is no room for the operator's preferences. Therefore, even if it would be more efficient to use the system by changing it according to the operator's preference, this is not possible and is inconvenient.

In order to eliminate these drawbacks, the following electronic canoyu register has been considered.

In other words, there are devices that allow the user to freely assign functions to keys arranged in a matrix by operating each key on the keyboard, thereby allowing the user to obtain a desired keyboard pattern ( (See Japanese Patent Application Laid-Open No. 59-55568).

With this device, the operator has to set the functions for each key on the keyboard one by one, so it takes a lot of time to set the functions. Therefore, if operators with different operating characteristics frequently take turns using the
If a right-handed operator uses the device in the morning and a left-handed operator uses it in the afternoon, the above-mentioned setting work must be performed each time the operator changes positions, which is impractical.

In order to eliminate this drawback, the following electronic canoyu register has been considered.

In other words, by storing multiple key layouts in which each key on the keyboard is assigned a predetermined function as a keyboard pattern, and by assigning a recognition number to each keyboard pattern to distinguish them, by inputting this recognition number. There is a system in which a desired keyboard pattern is selected and called up for use (Japanese Patent Laid-Open No. 63-8991).
(see publication).

This device allows you to easily and quickly assign functions to each key on the keyboard by entering a specific recognition number, and has the effect of easily obtaining the desired keyboard pattern. do.

``Problems to be Solved by the Invention'' However, in such conventional electronic cash registers, the user inputs a specific identification number to select a desired keyboard pattern, which has the following disadvantages. .

That is, since this input operation of the identification number is an operation that has not been performed up to now, there is a drawback in that an operator accustomed to normal operations finds this manual operation extremely troublesome.

Furthermore, if this input operation is forgotten, the keyboard pattern will be different from the desired one, and there is a drawback that the user may unknowingly make a key operation error.

Furthermore, the operator must memorize the number that corresponds to the keyboard pattern he or she desires, and if he or she enters the wrong number, he or she may make a key operation error in the same way as described above. There are drawbacks.

Furthermore, the conventional method has a drawback in that it is possible to select and use any of the prepared keyboard patterns by simply inputting an identification number for keyboard pattern selection. Here, electronic cash registers are often operated by amateurs such as part-time workers. Therefore, if you can select and use any keyboard pattern, you may end up operating extra keys other than those used for normal operations (especially important keys assigned to tasks such as aggregation and unit price changes).
The drawback is that it can cause confusion in business operations.

The present invention has been made in view of the above circumstances, and it is possible to obtain a keyboard pattern suitable for each operator without performing extra operations, thereby preventing key operation errors and business confusion. The purpose of the present invention is to provide a sales data processing device that can perform the following tasks.

"Means for Solving the Problems" A first sales data processing device of the present invention is a sales data processing device equipped with a keyboard in which keys are arranged in a matrix, and a plurality of functions are assigned to the keys. a code input means for inputting an operator code assigned to an operator; and a code input means for inputting a specific keyboard pattern from the storage means based on the operator code input from the code input means. It is characterized by comprising a calling means for selectively calling.

Further, a second sales data processing device of the present invention is a sales data processing device equipped with a keyboard in which keys are arranged in a matrix, and includes a memory that stores a plurality of keyboard patterns in which functions are assigned to the keys. code input means for inputting an operator code assigned to an operator; calling means for selecting and calling a specific keyboard pattern from the storage means based on the operator code input from the code input means; and display changing means for changing the display on the keyboard in accordance with the keyboard pattern called up by the calling means.

"Operation" In the present invention, when the operator code is input, the keyboard pattern desired by the operator is automatically selected from the storage means based on the operator code. In this type of device,
Inputting the handler code prior to use is an essential operation for purposes such as aggregating transaction data by handler and printing the person in charge of processing on the receipt. Therefore, the operator can automatically obtain a desired keyboard pattern without performing any extra operations, and key operation errors are prevented.

Further, since the keyboard pattern is selected depending on the operator, it is possible to limit the keys that can be operated depending on each operator, for example. Therefore, it is possible to prevent the operator from accidentally operating an extra key and causing confusion in the work.

"Example" Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the external structure of an electronic cassocket register according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the electrical configuration.

■ is the keyboard. This keyboard 1 has a function key 1a consisting of various keys such as a "subtotal" key and a "current total" key, and a numeric keypad 1 for inputting the amount and number of products.
b, and product information set in advance for each product (product name,
unit price, etc.). 2 is a reading window for the barcode reader 3 shown in Fig. 2, and when a product with a barcode is placed on it or passed through it, the barcode is automatically scanned and read. It is now possible to

Reference numeral 4 denotes a display device consisting of a display 4a for store staff and a display 4b for customers. The product name and price are displayed. This display device 4 displays the total amount and various messages.

Further, 5 is a printing device, which is composed of a receipt printing section 5a and a journal printing section 5a. In addition, 6 in Figure 1 is a coin case, 7 is a bill case, 8 is an accessory case, 1
0 is a control section storage section that houses the control section.

This control section has a configuration as shown in FIG.

That is, the keyboard l is connected to the CPU 20 via the keyboard interface 11, and the barcode reader 3 is connected to the CPU 2 via the interface 13.
Connected to 0.

Further, the display device 4 is connected to the CPU 20 via a display controller 14, and the printing device 5 is connected to the CPU 20 via a printer controller 15. In addition, 16 in the figure is an external interface interposed between the external device 17.

The CPU 20 performs processing according to a control program stored in the ROM 21, using the RAM 22 as a work area.

As shown in FIG. 3, the operator code 30 is stored in the RAM 22.
an operator register 31 in which operator codes 30 and keyboard pattern recognition numbers (abbreviated as recognition numbers in the figure) 32 are stored in association with each other; A function allocation table 34 is provided for each number 32 in which function allocation data for each key is stored.

The electronic cash register of this embodiment cannot be used until the handler code 3o is entered, as it is necessary to aggregate transaction data on the handler side and print the person in charge of processing on the receipt. It is now impossible to do so. Therefore, when the operator is replaced, the operator code 30 must be input. This operator code 30 is stored in the operator register 31 and is used for processing to be described later.

As shown in FIG. 4 (+L), the keyboard 1 has ten keys 40 arranged in a matrix in the width direction and five keys 40 in the depth direction. Key 40 in Figure 4 (2L)
The numbers inside indicate the numbers of the keys 40. and,
As shown in FIG. 4(b) and FIG. 4(c), the numbers of each key 40 of the keyboard 1 have various functions ("user", "
Two types of keyboard patterns are stored in the function allocation table 34. In addition,
The numbers and symbols in these figures conceptually indicate the state in which functions are assigned, and do not indicate the actual surface state of the key, ie, the key top.

The one shown in FIG. 4(b) has functions assigned to right-handed users, and the one shown in FIG. 4(c) has functions assigned to left-handed users.

When each key 40 on the keyboard 1 is pressed, the key code (
(hard code) is uniquely determined. By assigning various functions to this hard code,
Two types of keyboard patterns as described above can be set.

Based on FIG. 5, the key tops when one of the two types of keyboard patterns is selected will be explained. In this case, since there are two types of keyboard patterns, if the key tops display one type of symbol or the like on - keys 40, the keyboard patterns cannot be distinguished, and the use of the key tops becomes difficult.

Therefore, a mechanism is required to switch the key tops in response to selecting a specific keyboard pattern. An example of this mechanism is shown below.

For example, the one shown in FIG. 5(a) has a key top with
Symbols corresponding to the two types of functions assigned are also listed.

The one shown in FIG. 5(b) has two kinds of symbols written on the key top, and has two built-in lamps inside the key 40 corresponding to the symbol notation, corresponding to the assigned functions. The symbol is illuminated from behind by a lamp. This figure shows the "returned bottle" illuminated.

In these embodiments, two types of symbols are displayed on the key tops, but three or more types of symbols may be displayed depending on the type of keyboard pattern. In this case, three or more types of keyboard patterns can be supported.

Furthermore, as another key top switching mechanism, the fifth
Something like the one shown in Figure (c) can be considered.

That is, grooves 41 extending in the same direction are provided in the upper part of the keys 40 arranged in the width direction, and windows 42 are provided in the front part of the grooves 41 at the same pitch as the arrangement pitch of the keys 40.
A band-shaped plate 43, on which two types of symbols are alternately displayed at the same pitch as the arrangement pitch, is inserted into the groove 41 so as to be freely movable forward and backward.

Then, when changing the keyboard pattern, the plate 43
The symbol exposed through the window 42 is changed by moving the key 40 forward or backward in the direction in which the key 40 is arranged, so that the change in the function of the key 40 can be seen from the front surface. In such a structure, by replacing and using the plates 43 on which symbols are displayed in various arrangements, the keyboard pattern is not limited to two types, but can be easily applied even when a plurality of keyboard patterns are set. I can do it.

Note that after the power to the electronic cash register is turned on, functions are assigned in advance to each key 40 of the keyboard l so that the arrangement is suitable for right-handed users as shown in FIG. 4(b). ing. The reason for this is that unless the arrangement of the keys 40 is determined when setting the keyboard pattern, it is not possible to input the operator code 30 as a condition for starting the operation.

As shown in FIG. 3, the operator table 33 stores keyboard pattern recognition numbers 32 used by operators in correspondence with operator codes 30.

In this embodiment, when "O" is stored in the keyboard recognition number 32, it indicates a right-handed keyboard pattern, and when rlJ is stored, it indicates a left-handed keyboard pattern. In other words, in Fig. 3, the person whose handler code 30 is "r1234" is right-handed, r1235.
Person J indicates that a left-handed item is selected.

Note that data is written and changed in the operator table 33 using the keyboard l. In this case, [0] is stored in the keyboard recognition number 32 as an initial value corresponding to the operator code 30. Therefore, especially when rlJ is not input as the keyboard recognition number 32, this initial value "0" remains unchanged.

Further, as shown in FIG. 3, the function allocation table 34 stores a function code corresponding to each function assigned to each key 40 number for each keyboard recognition number 32.

In the function allocation table 34 of this embodiment, when the keyboard recognition number 32 is "0", the function code corresponding to PI (preset key N011) is assigned to key number rlJ, and the function code corresponding to key number "2" is assigned to key number rlJ. P2 (preset key No.
The function code corresponding to 2) is assigned to the key number "50", and the function code corresponding to the subtotal key is assigned. In addition, in the case of keyboard recognition number rlJ, key number "1" has the function code corresponding to the return bottle key, key number "2" has the function code corresponding to the checkout key, key number [50 " is PI5 (preset key NO, 15)
A corresponding function code has been assigned.

As shown in FIG. 3, when a specific keyboard recognition number 32 is selected and each key 40 of the keyboard l is pressed, based on the function code stored corresponding to that key 40, The program in ROM 21 is accessed.

As shown in FIG. 3, this ROM 21 includes a funk key processing program, a numeric key processing program,
It is equipped with a digital key processing program.

The funknoyon processing program includes a bottle return processing program 50, an accounting processing program 51, a subtotal processing program 52, and the like.

The numeric keypad processing program includes a "0" processing program 53, a "1" processing program 54, and the like.

The preset processing programs include the rP1j processing program 55, the "P2" processing program 56, . . .
It is composed of an rP15j processing program 57 and the like.

The control of this embodiment will be explained with reference to the flowchart shown in FIG. This control is executed by a program stored in the ROM 21.

Note that this flowchart shows the processing when the operator code 30 is input. In other words, after the operator enters the four-digit operator code assigned to him/her using the numeric keys, he/she can enter operator code 3 by pressing the "operator" key.
When 0 is input, step IO is executed first.

Step 10 (hereinafter referred to as SIO in the figure)
Then, the input operator code 30 is stored in the operator register 31 in the RAM 22. The handler code 30 is used when performing processing such as aggregating items by handler or printing the handler on a receipt.

In step 11, based on the operator code 30 taken into the operator register 31, a flag is set for a specific function permitted to the operator code 30. this is,
This allows important business functions such as data clearing and unit price changes to be restricted for each user.

This flag is referenced when executing a process after a key operation, and only the function for which the flag is set is executed.

In step 12, the operator table 33 is referred to to determine whether the keyboard pattern recognition number 32 stored corresponding to the operator code 30 is rlJ. If this is rlJ, proceed to step 13. here,
The reason why the keyboard pattern recognition number 32 is not compared with "0" is because the keyboard pattern recognition number 32 is set to "0" when the electronic cash reno star is turned on as described above. , since there are only two types of keyboard pattern recognition numbers 32, "1" and "0",
This is because it is sufficient to detect only cases other than "0".

In step 13, settings are made to select the recognition number 32 of "1" from the function allocation table 34. This setting selects the key layout.

That is, when the key 40 is pressed, the function assigned to the key 40 is performed by accessing a specific program in the ROM 21 based on the table whose identification number 32 is rll. As a result, the keyboard 1 functions as a left-handed keyboard with the read keyboard pattern recognition number 32 rlJ.

Note that if necessary in step 13 above (the fifth
(b) and (c)), key top change processing is also performed.

As explained above, in this embodiment, when the operator inputs the operator code 30 at the start of operation, this operator code 3
Keyboard pattern recognition number 3 set corresponding to 0
2 is obtained. Then, corresponding to this keyboard pattern recognition number 32, the keyboard l is changed to a keyboard pattern suitable for the operator. Therefore, each operator can work with the most suitable keyboard pattern.

Furthermore, in the electronic canyurenosta of this embodiment, in order to perform aggregation by operator, the operator's code must be input at the start of operation or at the time of change. Therefore, you can automatically change the keyboard pattern to your own style without any additional operations.

Further, since a desired keyboard pattern is automatically selected based on the operator code 30, there is no possibility of key operation errors due to incorrect operations or failure to perform predetermined operations.

FIG. 7 shows a keyboard in an electronic cash register according to another embodiment of the present invention.

This device has a liquid crystal display 6 as shown in FIG. 7(a).
A touch panel 61 is disposed on the top surface of 0, and data can be displayed and data inputted on the same surface. Incidentally, this liquid crystal display 60 can display various patterns as key tops by displaying 480×200 dots as described later.

The touch panel 6 is provided on the top surface of the liquid crystal display 60, and when an operator touches the top surface of the liquid crystal display 60, the touched position is detected. That is, around the liquid crystal display 60, five light emitting diodes 62 are provided on the left side, and five phototransistors 63 are provided on the right side, facing each other. Furthermore, 10 light emitting diodes 6 (the number is omitted in the figure) are placed on the upper side.
There are 10 pieces of 4 on the bottom side (also, the number is omitted).
phototransistors 65 are provided to face each other. Light emitting diode 6264 and food transistor 63
．． Each intersection of the optical axis with 65 acts as a key.

At the intersection of the optical axes on the liquid crystal display 60, key tops corresponding to the assigned functions are displayed. This key top image is stored in the ROM 21 in correspondence with each key function code, as shown in FIG. 1O.

As shown in FIG. 7(b), when the touch panel 61 is touched with a finger, light emitting diodes 62 and 64 are displayed opposite to the touched position.
and the phototransistor 6365 are cut off.

As a result, the touched position is recognized and a function assigned to that position is input.

Note that various keyboard patterns can be displayed as appropriate by changing the arrangement of symbols and the like displayed on the liquid crystal display 6o. Manufacturers try to memorize multiple frequently used keyboard patterns in advance.
Specially convenient for the user (according to the operator's preference)
You can also freely set and register keyboard patterns. Examples of the settings are shown in FIGS. 8(a) to 8(g).

That is, what is shown in FIG. 8(a) is the liquid crystal display 60.
On the surface of the preset key group 70. A first function key group 73, a numeric keypad 72, and a second function key group 71 are displayed. This display state is normally suitable for use by a right-handed operator. Note that areas outside the key groups 70 to 73 are areas to which functions are not assigned, and are disabled even if touched (the same applies to each side shown below).

).

In the case shown in FIG. 8(b), on the surface of the liquid crystal display 6o,
Preset key group 7o, first fan key group 73
, numeric keypad 72, and second function key group 71 are displayed. This display state is generally suitable for use by left-handed operators.

The one shown in FIG. 8(c) is a funk key that integrates a first funk key group 73 and a second funk key 71 between a preset key group 7o and a numeric keypad 72 on a liquid crystal display 6o. A group 74 is displayed.

In the case shown in FIG. 8(d), on the surface of the liquid crystal display 60,
A preset key group 70, a numeric keypad 72, and a first function key group 73 are displayed side by side in the horizontal direction, and a second function key group 71 is displayed above them.

In the case shown in FIG. 8(e), the size of the - key top is larger than the other key tops. The one shown in this figure is a so-called double key in which the "deposit/account" key is twice the size of the other keys, improving operability. In this case, try to allocate the same function to adjacent areas. Furthermore, the key top image (in this case, "Cash/Cash") is stored so that it occupies two adjacent areas.

In the case shown in FIG. 8(f), on the surface of the liquid crystal display 60,
A key top image indicating a specific function (in the figure, "Deposit/Cash") is displayed independently. By displaying the key tops independently in this way, it is possible to reduce key mistouches.

In the case shown in FIG. 8(g), a store clerk display section 75 is displayed above each of the key groups 70 to 73 on the liquid crystal display 60. This clerk side display section 75 displays numerical values, characters, etc. in order to confirm input items, amounts, etc.

Furthermore, regarding the display of the key tops of the liquid crystal display 60, keys indicating functions that are prohibited from being operated by the operator may not be displayed. In this way, the display becomes simple, key operations become easier, and erroneous touches can be reduced.

As explained above, it is possible to allocate each function to an area on the liquid crystal display 60 and to change the key top image displayed on the area corresponding to each area as appropriate depending on the purpose, operator, etc. Therefore, each user can use the keyboard l with the optimal keyboard pattern.

In this embodiment, as in the above-described embodiments, a handler table 33 as shown in FIG. 9(a) is stored in the RAM 22. Keyboard pattern recognition numbers 32 corresponding to various keyboard patterns as described above are stored in correspondence with operator codes 30. In this embodiment, the keyboard recognition number 32 stores any one of "0" to rNJ. For example, in this embodiment, operator code 3
If 0 is rl 234J, "0" is stored, and if it is "r1235", "2" is stored.

Also, in this example, as in the above-mentioned example, FIG.
As shown in b), a function allocation table 34 is provided. In this function allocation table 34, function codes corresponding to each function are allocated and stored for each key 40 number in correspondence with the keyboard recognition number 32. For example, in this embodiment, when the keyboard recognition number 32 is "0", the function code (5001) of Pi (preset key No. 1) is assigned to the key number rlJ, and the key number "rlJ" is "0".
2" is assigned the function code (5002) of P2 (preset key No. 2).

In the case of keyboard recognition number "1", key number rlJ contains the function code (1005) corresponding to the accounting key.
has been allocated.

In addition, in FIG. 9(b), the function code (0000) is
Indicates that there are no allocated functions.

When each key 40 on the keyboard l is pressed, that key 40
Based on the function code corresponding to the RO shown in FIG.
The key processing program of M22 is to be accessed.

This ROM 21 includes a funk key processing program 80, a numeric keypad processing program 81, and a preset key processing program 82, as in the above embodiment.

The control of this embodiment will be explained with reference to the flowchart shown in FIG. This control is executed by a program stored in the ROM 21.

Note that this flowchart shows the processing when the operator code 30 is input.

In step 20, the input operator code 30 is sent to the RA.
It is stored in the handler register 31 in M22.

Similar to the above-described embodiment, the handler code 30 is used when data is aggregated on the handler side and when the handler is printed on the notebook.

In step 21, based on the operator code 30 taken into the operator register 31, a flag is set for a specific function permitted to the operator code 30. This is a single feature that allows operators to restrict important business functions such as data clearing and unit price changes. This flag is referenced when executing the process assigned to the key 40 after a specific key is pressed.
Only certain functions with flags set will be executed.

In step 22, the operator table 33 is referred to to determine whether the keyboard pattern recognition number 32 stored corresponding to the operator code 30 is "0". "0"
If not, proceed to step 23.

In step 23, it is determined whether the keyboard pattern recognition number 32 is rlJ. If the result is [1], the process advances to step 24.

In step 24, settings are made to select the keyboard pattern recognition number 32 of rlJ from the function allocation table 34. .

In step 25, a specific key top image is displayed on the liquid crystal display 60 at a position corresponding to each key. When a specific key 40 is pressed, the key 40 is accessed by accessing a specific program in the ROM 21.
I am trying to fulfill the functions assigned to me. Therefore, the keyboard 1 functions as a keyboard whose read keyboard pattern recognition number 32 corresponds to rlJ.

In step 23, the keyboard pattern recognition number 32
is other than rlJ, steps corresponding to step 23 are repeated until the keyboard pattern recognition number 32 corresponding to the operator code 30 is matched.

With conventional electronic cash registers, the keys normally used to input product names, amounts, etc. are substituted for keyboard pattern settings, making operations in the setting mode difficult to understand. Setting operations were complicated.

However, in this embodiment, since the keyboard is configured with a liquid crystal display 60, this display can be easily changed to one exclusively for keyboard pattern setting. Therefore, setting operations can be easily performed.

The procedure and guidance for this setting operation can be seen on the LCD display 60.
It can also be displayed on the screen, making setting operations even easier.

In each of the embodiments described above, the operator code 30 is input from the numeric keypad of the keyboard 1.
Any appropriate method can be used to input 0. For example, a barcode card, magnetic card, or IC card created for each operator can be used. Note that the operator may be distinguished by voice input.

In the above embodiment, the electronic cash register is turned off.
An initial value is set to the keyboard pattern recognition number 32 so that the operator code 30 can be entered immediately after entering N. However, if an input method other than the keyboard is used, such an initial value It is not necessary to set.

In each of the embodiments described above, all the keys 40 making up the keyboard pattern are changed depending on the operator, but even if the pattern of some keys 40 in the keyboard 1 is changed. good.

Although the above embodiments were applied to electronic cash registers, similar effects can be obtained by applying the present invention to POS registers that require input of operator codes, electronic scales for face-to-face sales, and the like.

"Effects of the Invention" As explained above, according to the sales data processing device of the present invention, a plurality of keyboard patterns in which functions are assigned to keys can be stored, and the operator code assigned to the operator can be inputted. Then, a specific keyboard pattern is selected and called based on this operator code. In this type of device, inputting a handler code prior to use is an essential operation for purposes such as aggregating transaction data for each handler. Therefore, a keyboard pattern suitable for each operator can be obtained without performing any extra operations. Also, you will never forget to select a keyboard pattern. Therefore, it is possible to prevent a single key operation error and business confusion.
