Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a classification processing device, and is effectively applied to, for example, an electronic cash register (hereinafter referred to as ECR).

Typically, an ECR is provided with a plurality of classification keys such as item keys and department keys.

Here, the item key specifies an individual category such as coffee or tea, and the department key specifies a broad category such as drinks or noodles.

These examples are cases in which the ECR is used in a restaurant, but if the ECR is used in other fields, the specified contents of the item key and department key will naturally become different.

By the way, the optimal number of item keys and department keys to install is E.
Depending on the user who uses the CR, it may be desirable for some users to install more item keys than department keys, or vice versa.

However, for ECR manufacturers, it is extremely troublesome to allocate the above classification keys to each user, and it is not suitable for mass production. is kept constant, and each user can freely allocate the number of item keys and department keys.

The present invention will be explained in detail in Examples below.

In the figure, 1 is a first manual means, which includes a plurality of classification keys that are item keys or department keys.

2 is an encoder for encoding the key signal from the first human power means 1 into a binary code, and 3 is for addressing each storage area 5, 5, etc. of the storage means 4 based on the output of the encoder. This is an address circuit.

That is, each storage area 5, 5, . . . of the storage means 4 is the first
It corresponds to each classification key of the human power means 1, and when an arbitrary classification key is operated in the first human power means 1, the contents of the corresponding storage area are read out.

6 is presetting means, which includes a rotary switch and a writing switch for setting numbers.

When the write switch of the preset means 6 is turned on, the ON signal is input to the storage means 4 via the control line 7, and while the write switch is on, the storage means 4 changes to the write state.

In this state, when a classification key is operated in the first manual means 1, the numerical data set by the rotary switch of the preset means 6 is written into the corresponding storage area 5.

Denoted at 8 is a determining means for determining whether or not the content read from the storage means 4 is zero. If the content is zero, the first AND gate 9 is opened, and if it is not zero, the second and third AND gates 10 are opened.
, 11 are opened.

12 to 14 are first to third display sections, each of which includes a display register and a numeric display connected to the register.

15 is a second manual means having a numeric key and a registration key; 16
is an encoder which converts the key signal of the means into a binary code if it corresponds to a numeric key and generates a control signal on line 17 if it corresponds to a registered key.

The numeric data output from the encoder 16 is transmitted to the first or second display unit 12 .
Enter 13.

Further, the content read from the storage means 4 is input to the first display section 12 via the third AND gate 11.

Furthermore, data from the encoder 2 is entered into the third display section 14, and the classification key number operated by the first human power means 1 is displayed as the third display section 14.
It is displayed on the display unit 14.

That is, each of the classification keys is assigned a key number for convenience, and for example, when the number 3 classification key is operated, "3" is displayed on the third display section 14.

18 is an arithmetic and control unit, and when this unit receives a signal from the output line 17 of the encoder 16, it outputs the address circuit 3.
Based on the output data of 1. It processes the data on the second display section 12, 13, stores the processed data in the main storage means 19, displays it on the fourth display section 20, and also performs control over each of the above-mentioned display sections, such as clear control.

The operation of the above apparatus including the unit 18 will be further explained below.

In the figure, thick lines and thin lines indicate the flow of data and control signals, respectively.

First, when the user who will use the device is determined, the presetting means 6 is used to assign the item key to the department key.

For example, if the total number of classification keys of the first manual means 1 is 20, and each key is assigned a key number from 1 to 20, then When the key is used as an item key and each key from No. 16 to No. 20 and No. 1 is used as a department key, first set the unit price for the No. 1 key item using the rotary switch in the presetting means 6, and also switch the writing switch. is turned on to put the storage means 4 into a writing state, and then the No. 1 key is operated.

As a result, the unit price is written 1 in the storage area 5 corresponding to the No. 1 key.

Similarly, the unit price corresponding to the storage area corresponding to each key at number 15 is written, and zero is written to the storage area corresponding to each key at number 16 to number 20.

Finally, by turning off the write switch, the assignment of the item key and department key is completed.

Note that when the above-mentioned key is operated, the number of the key operated is displayed on the third display section 14.

Thereafter, the user can use each classification key from No. 1 to No. 15 of the first manual means 1 as an item key, and each classification key from No. 16 to No. 20 as a department key. The processing operation is as follows.

For example, when item key No. 5 is operated, the key number is displayed on the third display section 14, and the contents of the corresponding storage area are read out from the storage means 4.

Since this content is a unit price and is therefore not zero, the second and third AND gates 10 and 11 are opened by the action of the determining means 8, so that the unit price read out above is displayed on the first display section 12.
is entered and displayed.

Next, when the number of the corresponding item is inputted in the second manual means 15, the contents are entered into the second display section 13 and displayed.

Finally, when the registration key is operated in the second manual means 15, the unit 18, based on the information from the address circuit 3, recognizes that item processing is being performed, and displays the first and second display sections 12.1.
3 is multiplied between each content, and the result is displayed as the total amount on the fourth display unit 20, and the result is accumulated and stored in the corresponding item area of the main storage means 19.

After such processing, the unit 18 displays the first to fourth display sections 12 to
14. Clear 20 and place the device in a new input standby state.

Next, when the department key No. 18 is operated, the key number is displayed on the third display section 14, and the contents of the corresponding storage area are read out from the storage means 4.

Since this content is zero, the first AND gate 12 is opened by the action of the determining means 8, and therefore the second manual means 15 is then opened.
When the user inputs the amount of the item, the content is entered into the first display section 12 and displayed.

Finally, when the registration key is operated in the second manual means 15, the unit 18 learns that it is a departmental process based on the information from the address circuit 3, and stores the contents of the first display section 12 in the corresponding department area of the main storage means 19. The cumulative value is stored in the memory.

The unit 18 similarly then places the device in an input standby state.

In the above embodiment, the rotary switch of the presetting means 6 can also be used as the numeric keys of the second manual means 15.

As is clear from the above explanation, according to the present invention, the total number of classification keys is fixed and the number of item keys and department keys can be freely assigned to each user. This makes it suitable for mass production.
