Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a data processing system such as an electronic register, a POS system, and an office computer.

[Prior Art] In recent years, for example, a non-connection type hand scanner is equipped with a PLU memory or a registration memory, and based on a bar code read by this hand scanner, the hand scanner itself calculates the total number of sales by PLU and the like. Performs registration processing such as cumulative storage and sales data for one registration, and connects this hand scanner to the electronic register body to transfer the contents of one registration memory to the electronic register body, and to the electronic register body. Electronic registers that issue receipts are being considered.

[Problems to be solved by the invention] By the way, in such an electronic register, when the electronic register main body is provided with a memory for each operator and the registration data is collected for each operator in this memory,
In order to specify the memory, it is necessary to enter operator identification data such as an operator code and perform sign-in / sign-off processing to enable data collection for each operator.To issue a receipt, It is troublesome to input operator identification data every time the hand scanner is connected to the electronic register body.

As a method to solve this problem, a dedicated hand scanner is assigned to each operator, operator identification data is preset in the storage medium in the assigned hand scanner, and when this hand scanner is connected to the electronic register body, It is also possible to consider a method of automatically transmitting preset operator identification data to the electronic register body.

However, in this method, one electronic register main body can be shared by a plurality of hand scanners.
It is impossible for a plurality of operators to share a single hand scanner.

This is because the storage medium of the hand scanner is fixedly mounted on the hand scanner, and the hand scanner and the storage medium have a one-to-one correspondence.

Then, the storage medium that can be freely attached to and detached from the hand scanner is utilized, and the operator identification data is preset in each storage medium so that the storage medium and the operator have a one-to-one correspondence. When a hand scanner equipped with a preset storage medium is connected to the electronic cash register body, the operator identification data preset in the storage medium is automatically transmitted to the electronic cash register body. It is possible to easily input operator identification data when collecting registration data for each operator in the electronic register body while sharing one hand scanner with multiple operators while sharing one hand scanner. Is easy to understand.

An object of this invention is to enable data processing by utilizing a storage medium to transmit operator identification data.

[Means for Solving the Problems] The means of the present invention are as follows.

The data processing system includes a data processing device having a data receiving function and a data processing function, and a data input device separately provided from the data processing device and having a data input function and a data transmission function. The data input device normally inputs data when it is not connected to the data processing device, and when the data processing device is connected, the data input device is connected to the data input device and is input when not connected. The received data is received and predetermined data processing is performed. For example, if this data processing system is a POS system, the data processing device is an electronic register, the data input device is a hand scanner, and the sales data for one registration is registered by the hand scanner in the unconnected state. Then, the electronic register issues a receipt.

The mounting means a1 of the data input device a (see the functional block diagram of FIG. 1, the same applies hereinafter) detachably mounts an IC card CD in which operator identification data is preset.

The writing means a2 of the data processing device b writes the data input by the data input device a into the IC card CD mounted in the mounting means a1.

The transmission means a3 of the data processing device b is written by at least the operator identification data preset in the IC card CD and the writing means when connected to the data processing device b with the IC card CD mounted in the mounting means a1. Sent input data.

The storage means b1 of the data processing device b is preset with operator identification data.

The receiving means b2 of the data processing device b receives the operator identification data and the input data transmitted from the transmitting means a3 of the data input device a.

The discrimination means b3 of the data processing device b discriminates whether the operator identification data received by the reception means b2 is preset in the storage means b1.

When the discriminating means b3 discriminates that the operator identification data relating to the transmission is preset, the permitting means b4 of the data processing device b collects the input data written in the IC card CD, and the like. Allows you to perform data processing.

[Operation] The operation of the means of this invention is as follows.

The operator, for example, mounts the IC card CD preset with his or her own operator identification data in the mounting means a1 of the data input device a, and inputs the data. Then, the writing means a2 writes the input data to the mounted IC card CD.

Then, when the data input device a is connected to the data processing device b with the IC card CD still attached, the transmission means a3
Sends at least the operator identification data preset in the IC card CD and the input data written in the IC card CD to the data processing device b.

In the data processing device b, the receiving means b2 receives the transmitted operator identification data and input data, and the determining means b3 determines whether the received operator identifying data is preset in the storage means b1.

When the discrimination means b3 discriminates that the operator identification data relating to the transmission is preset in the storage means, the permitting means b4 performs data processing such as totalizing and storing the input data written in the IC card CD. Allow

That is, if the data input device is connected to the data processing device with the IC card CD still attached, the operator identification data is automatically input to the data processing device, and it is not necessary to input the operator identification data by key operation. Also, sign / in processing and the like for collecting input data for each operator is performed.

Therefore, when the data input device is connected to the data processing device by each operator, the operator identification data to be transmitted in order to be aggregated in the data processing device by the operator is stored as data. This makes it easy to utilize a storage medium that can be attached to and detached from the input device.

The busy flag F2 is set when the personal identification number transmitted from the hand scanner A together with the sales data for one registration is preset in the operator totaling file FL3, and the hand scanner A is removed from the adapter B1. Sometimes reset. Then, by setting the busy flag F2, access to the records for the operator of the personal identification number is permitted. That is, the sign-in process is performed. That is, the busy flag F2 indicates sign-in when set and sign-off when reset.

The NG flag F1 is set when the personal identification number from the hand scanner A is not preset in the operator-specific aggregate file FL3.

Next, the operation of the embodiment will be described with reference to FIGS.

First, the process of setting the personal identification number by the personal computer PC will be described.

PC When the personal identification number setting mode is set, the personal computer waits for the personal identification number to be input (step PS1 in Fig. 8).
The PFL is searched (step PS2), and it is determined whether or not the entered personal identification number is preset in the operator-specific master file PFL (step PS3). As a result, if it is not preset, check if it is an operator addition (step PS4), and if it is addition,
Wait for the operator name of the operator to be added (step PS5). Then, when the operator name is input, the operator name is added to the operator-specific master file PFL and the operator-specific aggregation file FL3 of the repeater B together with the previously entered personal identification number (steps PS6, PS
7) Write the input security code into the security code memory M2 in the IC card CD (step PS8) and return to step PS1.

In step PS3, if the entered personal identification number is preset in the operator-specific master file PFL, it is a change of the personal identification number, that is, the entered personal identification number is the change target personal identification number. Determine if there is (step P
S9). As a result, if the personal identification number is changed, the input of the personal identification number relating to the change is waited for (step PS10), and if the personal identification number relating to the change is input, the master file PFL for each operator and the repeater B Change the personal identification number to be changed in the operator-specific aggregate file FL3 to the personal identification number related to the change (steps PS11 and PS12), and proceed to step PS8 to IC card CD
The personal identification number memory M2 in is overwritten with the personal identification number related to the change.

In step PS9, it is determined that the process is not the change of the personal identification number but another process such as changing the operator name corresponding to the input personal identification number, erasing the record of the input personal identification number itself. When, other processing is executed (step PS1
3).

Next, a series of registration processes will be described with reference to FIGS. 9 and 10.

When the bar code is read, the CPU 15 of the hand scanner A updates the sales data of the corresponding product in the PLU file FL1 in the mounted IC card based on the bar code. Read from file FL1 and store in one registration memory M1 with barcode, display
Perform registration processing such as displaying on A3 (Fig. 9, step S
1).

Then, it is judged whether or not it is in the registration waiting state (step
S2) If it is in the registration waiting state, the process returns to step S1 to continue the registration process. If it is not in the registration waiting state, it is determined whether or not there is a post-transaction (step S3), and if there is a post-transaction, post-transaction processing such as discounting and returning (returning) is performed on the PLU file FL1 and one registration memory M1. Perform (step S4). Next, a guide is displayed on the display unit A3 to connect the hand scanner A to the adapter B1 (step S5), and the connection is waited (step S6). In addition,
If it is determined in step S3 that there is no post-transaction, the process immediately proceeds to step S5.

When the hand scanner A is connected to the adapter B1, the personal identification number is read from the personal identification number memory M2 in the IC card (step S7), and the read personal identification number is registered in the registered memory M.
It is sent to the repeater B (adapter B1) together with the sales data for one registration in 1 (step S8).

The CPU 51 of the repeater B uses the secret code from the hand scanner A,
And when the sales data for one registration is received, the operator-specific aggregate file FL3 is searched (step S51 in FIG. 10),
It is determined whether or not the received personal identification number is preset (step S52).

As a result, when the received personal identification number is preset, the sign-in process is performed by setting the busy flag of the corresponding operator (step S5).
3). Then, finalization processing such as deposit amount input processing and change calculation is performed (step S54), and it is determined whether or not the finalization processing is completed (step S55).
). If the finalizing process is not completed, the process returns to step S54 to continue the finalizing process, and if the finalizing process is completed, receipt printing is performed by the printer B2 (step S56).

Next, by searching the records in the operator-specific aggregate file FL3 for which the busy flag is set,
The operator's record corresponding to the received personal identification number is searched, the sales data of the searched record is updated based on the received sales data for one registration, and the data in one registration memory M1 is cleared by the hand scanner A. (Step S57). Based on this instruction, the hand scanner A clears the data in the one registration memory M1 and displays a guide to cancel the connection.

Then, the CPU 51 of the repeater B waits for the hand scanner A to be disconnected (step S58). When the hand scanner A is disconnected, the CPU 51 of the relay B resets the busy flag in the set of the updated record, thereby performing the sign-off processing. Is performed (step S59), and the process ends.

In this way, the sign-in processing and the sign-off processing for totaling the sales data for each operator are automatically executed without key input of the personal identification number.

In step S52, if it is determined that the received personal identification number is not preset in the operator-specific aggregate file FL3, the personal identification number is not preset in the IC.
Recognizing that the card CD has been used,
The hand scanner A is instructed to set the NG flag F1 (step S60). Then, the deposit amount input process and the finalization process such as change calculation are performed (step S6).
1) It is determined whether or not the finalizing process is completed (step S62). If the finalizing process is not completed, the process returns to step S61 to continue the finalizing process, and if the finalizing process is completed, receipt printing is performed by the printer B2 (step S63).

Next, the hand scanner A is instructed to update the data of the temporary file FL2 in the IC card CD based on the data of the one registered memory M1 (step S64), and its own NG flag F2 is set (step S65). ),finish.

The hand scanner A sets the NG flag F1 based on the above instruction, updates the data in the temporary file FL2 based on the data in the one registration memory M1, and clears the data in the one registration memory M1. At the same time, a guide is displayed to disconnect the connection. Further, by setting the NG flags F1 and F2, it is possible to know that there is an operator omission in the operator-specific aggregate file FL3 and the operator-specific master file PFL. In this case, the omission supplement is performed using the temporary file FL2.

The series of registration processes described above can be performed by using the IC card preset with the personal identification number and using the arbitrary hand scanner A and the arbitrary relay device B. That is, the floating cashier process can be performed without manually inputting the personal identification number.

[Modified example] In addition, when writing the PIN code to the IC card, read the IC card /
By using the hand scanner itself to write in the following manner, regardless of the writing device RW, the IC card reading / writing device RW
It is also possible to prevent others from acquiring and misusing the IC card in which the No. is written.

In this case, the secret code to the operator-specific aggregate file FL3,
Write the operator name in advance using a personal computer.

The 11th writing process of the secret code by the hand scanner A itself
This will be described with reference to the drawings and FIG.

When the security code writing mode is set with the specified key,
CPU1 of hand scanner A waits for the input of the security code (first
1 step S101), when the personal identification number is entered, the number of digits is checked (step S102), and it is determined whether the number of digits is according to the standard (step S103). , Input secret code No. is total file by operator F
It inquires of the repeater B whether it is preset to L3 (step S104). Then, it is judged whether or not the ACK signal is received from the repeater B (step S105), and when the ACK signal is received, the inputted personal identification number is written in the IC card storage memory M1 in the IC card CD. (Step S106),
finish.

If it is determined in step S103 that the number of digits does not conform to the standard, and if it is determined in step S105 that the NAC signal has been received, error processing is performed (step S1.
07), end.

On the other hand, on the repeater B side, in response to the above inquiry, the operator-specific aggregate file FL3 is searched (step S20 in FIG. 12).
1), it is determined whether or not the personal identification number related to the inquiry is preset (step S202). As a result, if it exists, an ACK signal is transmitted to the hand scanner A (step S
203), if not present, send NAK signal to hand scanner A
To (step S204) and ends.

[Advantage of Invention] According to this invention, data processing can be performed by utilizing a storage medium to transmit operator identification data. Therefore, for example, the operator identification data to be transmitted in order to aggregate the data input by each operator at an arbitrary handheld input terminal into the processing apparatus main body for each operator is stored in the handheld input terminal as a removable storage medium. Can be used to easily enter.
