Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transaction processing device for face-to-face transactions between a customer and a store clerk. In particular, it relates to a transaction processing device that is characterized by its display method.

[Prior Art] Transaction processing devices are used at cash registers in supermarkets and the like. These devices include barcode scanners and turret displays. A barcode scanner reads the barcode of the product and displays the price on a turret display.

[Problems to be Solved by the Invention] However, conventional transaction processing devices have the following problems.

First, the display is unidirectional, making it difficult for either the customer or the store staff to view the display.

Secondly, if two indicators are provided to solve this problem,
Installation space must be secured, which also results in increased costs.

An object of the present invention is to solve the above-mentioned problems and provide a transaction processing device that is easy for both customers and store staff to view using a single display.

[Means for Solving the Problems] In the transaction processing device according to claim 1, the display device displays information for the customer and the clerk on the same screen, and displays information for the customer toward the customer,
The information for the store clerk is characterized in that it is displayed toward the store clerk.

[Operation] Since the display device displays information for the customer and the store staff on the same screen, the device can be made smaller. Furthermore, since the information for the customer is displayed toward the customer and the information for the store clerk is displayed toward the store clerk, the information can be easily viewed by both the customer and the store clerk.

[Embodiment] FIG. 2 shows a transaction processing device according to an embodiment of the present invention. A display device 6 is placed horizontally between a customer 2 and a store clerk 4. The display device 6 is attached with a card reader 8 and a barcode scanner 10. Display device 6 is connected to data processing device 14 via cable 12 . The display device 6 is also connected to a printer for printing receipts and a cash drawer. Furthermore, it is also connected to a computer that serves as a host. Note that, if necessary, a turret display may be connected separately from the display device 6, but normally the display device 6 alone is sufficient.

The hardware configuration of the display device 6 and data processing device 14 is shown in FIG. The display device 6 is under the control of the CPU 20.
Display 22, key manual section 24, card reader section 8
, memory 28, scanner interface 30. A serial interface 32 is provided.

The display 22 is for displaying information, and is an LC
D (liquid crystal), plasma, EL, CRT, etc. can be used. From the viewpoint of device miniaturization and power saving, it is preferable to use an LCD (liquid crystal), plasma, or EL. In addition, in terms of ease of viewing the display, when using an LCD, it is preferable to use one with a backlight.

The key input section 24 is for a customer or a clerk to input data. In this embodiment, a transparent touch panel is implemented by overlaying the display.

The card reader section 8 is for reading magnetic data such as credit cards and membership cards.

The scanner interface 30 is an interface that converts a signal from a scanner IO that reads a barcode attached to a product into data that can be recognized by the CPU 20 .

The serial interface 32 is an interface that converts parallel data into serial data in order to exchange data between the display device 6 and the data processing device 14. In this example, R3-232C is used. Note that data transmission may be performed as parallel data. Moreover, if wireless transmission is performed without using a cable, the degree of freedom in the installation position of the display device 6 and the data processing device 14 will be increased.

The memory 28 has a program area and a data area as shown in FIG. The CPU 20 is
Control each part according to the program in the program area.

The data processing device 14 includes a floppy disk drive 42, a hard disk 44, a serial interface 46, a memory 48, and a host communication interface 50 under the control of a CPU 40.

Floppy disk drive 42 and hard disk 4
4 is used to store large capacity file data. In this embodiment, a file area as shown in FIG. 6 is secured on the hard disk.

The serial interface 46 is the same as the serial interface 32 on the display device side.

Host communication interface 50 is used for data exchange with a host computer.

As shown in FIG. 6, the memory 48 has a program area and a data area. The CPU 40 is
Control each part according to the program in the program area.

An example of a transaction performed using the transaction processing device configured as described above will be described below.

The CPU 20 of the display device 6 is the CPU of the data processing device 14.
A command is issued to U40 to retrieve data necessary for initial display from hard disk 44 and store it in the buffer (memory 28). In the initial display, a customer-side key 60 and a clerk-side key 62 are displayed (see FIG. 1). Therefore, the key display data in the customer side display data and the key display data in the clerk side display data of the hard disk 44 are read out. The read key display data is stored in the customer side key buffer and the clerk side key buffer of the display device 6.

The CPU 20 executes the clerk side key control program and displays the contents of the clerk side key buffer on the V-RA of the display 22.
Write in M. As a result, the key 62 is displayed toward the clerk 4, as shown in FIG.

Next, the CPU 20 executes the customer side key control program and displays the contents of the customer side key buffer on the display 22. If the contents of the customer side key buffer are displayed as they are, the display will be directed towards the store clerk 4 side. However, in the present invention, the addresses are set so that when the contents of the customer side key buffer are written into the V-RAM of the display 22, the contents are upside down. Therefore, the key is displayed toward the customer 2. Keys 60, 62 thus displayed are shown in FIG. A transparent touch panel is placed on the display 22, so
This key 60, 62 serves as an input key.

The customer 2 comes in front of the display device 6 on which the initial display is displayed, carrying the product he/she wants to purchase. If the customer 2 wishes to pay by credit card, the clerk 4 swipes the card through the card reader 8. The CPU 20 executes the card reader control program shown in FIG. 5, and stores the data read from the card in the card data buffer. Note that the card stores data such as a customer number and a bank account number for withdrawal.

The customer 2 inputs the password from the person key 60. The entered PIN number is stored in the card data buffer. Therefore, this card data buffer stores the data read from the card and the input password.

The data stored in the card data buffer is transmitted to the data processing device 14 via the serial interface 32. In response to this, the CPU 40 executes the host communication control program shown in FIG. 6 and sends the data to the host computer.

The host computer receives the card data and determines whether there is any damage to the card. The determination result is sent back to the data processing device 14 via the data line 60. Furthermore, this judgment result data is sent to the display device 6 via the cable 12. The CPU 2Q looks at this data, and if the card is a proper card, it proceeds with the process, but if the card is an improper card (so-called accident card), it displays that fact and stops the process. The display at this time is performed based on the contents stored in the clerk side display buffer (read from the hard disk 44). The contents of the clerk's display buffer are stored in V-RAM without reversing the vertical position (address).
, so it will be displayed in the opposite direction from the previous customer-side key display. Therefore, the display of card suitability is displayed toward the clerk 4.

Next, the store clerk 4 uses the scanner 10 to read the barcode attached to the product brought by the customer 2. The read data is digitized via the scanner interface 30 and stored in the scanner data buffer as a product code. This product code is the data processing device 14
transmitted to. The CPU 40 searches the PLU file in the hard disk 44 based on this product code, and sends back the unit price of the product, etc. to the display device 6. Further, common display data is searched and image data of the product is also sent back to the display device 6.

In response to this, the display device 6 displays the unit price on the display 22 for both the customer and the store clerk, and displays an image of the product for the customer. The customer sees this
The confirmation key assigned to key 60 is pressed and the transaction is completed. By pressing the confirmation key, the transaction data will be
It is sent to the host computer via the host communication interface 50.

As described above, since the display is directed toward the customer and the store clerk, the display can be easily viewed by both parties.

Incidentally, a flowchart of display control is shown in FIG. First, in step S1, display data is received from the data processing device 14. A command indicating whether to display on the customer side, on the clerk side, or on both sides is added to the display data. In step Ss, it is determined whether the command attached to the display data is a customer-side display command. If it is a customer-side display command, the display data is
It is stored in the customer side display buffer shown in the figure and displayed upside down (step SS).

In step S2, if the command is a clerk-side display command, the display data is stored in the clerk-side display buffer shown in FIG. 5 and displayed (step SS).

Further, if it is a common display command, it is stored in both the customer side display buffer and the store clerk side display buffer, and is displayed for both the customer and the store clerk (step Ss,
Ss).

In this way, the display direction can be changed using commands, so the screen can be used effectively.

In the above embodiment, each function is realized by the CPU and software, but a part or all of it may be configured only by hardware.

[Effects of the Invention] In the transaction processing device according to claim 1, the display device displays information for the customer and the clerk on the same screen, and displays information for the customer toward the customer,
The information for the store clerk is characterized in that it is displayed toward the store clerk.

Therefore, since the display device displays information for the customer and the store staff on the same screen, it is possible to downsize the device. Furthermore, since the information for the customer is displayed toward the customer and the information for the store clerk is displayed toward the store clerk, the information can be easily viewed by both the customer and the store clerk. In addition, the screen can be used effectively.
