  According to the present invention, when the code scanner cannot read the code displayed on the screen of the mobile terminal, it is possible to accurately determine whether or not the cause is on the mobile terminal side or the code reader side. Code reader and code reading program can be provided.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, the present invention is applied to a POS terminal device.

  In FIG. 1, reference numeral 1 denotes a POS terminal device. The POS terminal device 1 has a keyboard 2, a liquid crystal display 3, a receipt issuing port 4, and a drawer 5 arranged on the front surface. Further, a barcode scanner 6 that reads a barcode as a code scanner is connected via a lead wire 7.

  FIG. 3 is a block diagram showing the configuration of the control unit. The CPU 11 constituting the control unit main body, the ROM (read only memory) 12 storing the program data for the CPU 11 to control each unit, and the CPU 11 are registered. A RAM (Random Access Memory) 13 for storing processing data such as processing data and calculation data, a keyboard controller 14 for controlling the keyboard 2 to capture key signals, and controlling the liquid crystal display 3 A display controller 15 for displaying the display data is provided.

  Also, a scanner controller 16 that controls the barcode scanner 6 to capture a barcode, a drawer drive unit 17 that drives the drawer 5 to open, and a printer 18 that prints registration data and the like on receipt paper and journal paper are provided. A printer controller 19 that controls and issues a receipt at the end of printing and a communication interface 20 that communicates with a host device are provided.

  The CPU 11, ROM 12, RAM 13, keyboard controller 14, display controller 15, scanner controller 16, drawer drive unit 17 and communication interface 20 are electrically connected to each other via a bus line 21.

  The barcode scanner 6 includes a barcode reading unit 61 that reads a barcode, and an output unit 62 that outputs the barcode data read by the barcode reading unit 61 to the scanner controller 16. The bar code reading unit 61 uses a lens and a sensor to detect a bar code. A sensor sensitivity adjustment unit 63 and a noise removal filter 64 are provided therein, and the sensor sensitivity adjustment unit 63 sets the gain of the sensor. The noise removal filter 64 removes noise from the detected data.

  The barcode scanner 6 is configured to read a barcode displayed on a portable terminal, for example, a display 8a of a cellular phone 8, or a barcode printed on a product. In general, the sensor sensitivity and the characteristics of the noise removal filter 64 are set to optimum values for reading the barcode printed on the product, and the barcode displayed on the display 8a of the mobile phone 8 is set. When reading, it is switched by a command from the CPU 11.

  The CPU 11 is configured to execute the work shown in FIG. 4 based on the program data stored in the ROM 12. That is, depending on the state of the mode switch, it is determined in S1 whether it is the charge proxy storage mode or the normal registration mode. If it is the normal registration mode, the normal registration mode is processed in S2.

  The normal registration mode process refers to a process for registering a product purchased by a customer. That is, by reading the barcode attached to the product with the barcode scanner 6, the scanned barcode is inquired of the host device via the communication interface 20, and the product name, unit price, department code, etc. of the corresponding product are obtained. The sales amount and the sales score are accumulated in a registration memory provided in the RAM 13, and the product name, unit price, and score are displayed on the liquid crystal display 3 and stored in the buffer of the RAM 13 as print data. This is repeated for the products to be registered, and finally the registration is closed on the keyboard 2 to display the total amount of money to be paid by the customer on the liquid crystal display 3 and print out a series of print data with the printer 18 and receive the receipt. Issue.

  If it is the charge proxy storage mode, processing of the charge proxy storage mode is performed in S3. The charge agent storage mode process is a process in which a barcode for payment displayed on the display 8a of the mobile phone 8 possessed by the client is read by the barcode scanner 6 and payment is made on behalf of the operator. is there. In this charge substitution storage mode, a mode change command is transmitted to the barcode scanner 6.

When the bar code scanner 6 receives the mode change command from the CPU 11, the sensor sensitivity adjustment unit 63 increases the sensor sensitivity, and the characteristic of the noise removal filter 64 is adapted to read the bar code from the mobile phone 8. Change.
In this state, the store operator performs an operation of reading the barcode by placing the barcode scanner 6 against the display 8 a of the mobile phone 8.

  The CPU 11 takes in the barcode data read from the scanner controller 16 and checks in S4 whether or not it has been read correctly as barcode data (determination means). If the barcode data is correctly read, the proxy storage process is executed in S5 (process execution means).

  If the barcode data has not been read correctly, in S6, it is displayed on the liquid crystal display 3 that it has not been read (notification means). In addition, you may notify with a buzzer.

At this time, as shown in FIG. 2, a simulated barcode 3a having the same code system as the read barcode is displayed on the liquid crystal display 3.
In this state, the store side operator touches the barcode scanner 6 against the simulated barcode 3 a displayed on the liquid crystal display 3 and performs an operation of reading the barcode.

  The CPU 11 takes in the barcode data read from the scanner controller 16 and checks whether or not the barcode data has been correctly read in S7 (determination means). If the barcode data is correctly read, in S8, the liquid crystal display 3 displays that the barcode scanner 6 is normal (result display means). If the barcode data is not correctly read, it is displayed in S9 that there is some abnormality in the barcode scanner 6 (result display means).

  In such a configuration, when using the mobile phone 8 held by the client to apply for payment, the store-side operator performs a mode switching operation of the POS terminal device 1 to start from the normal registration mode. Switch to charge agent storage mode. As a result, the sensor sensitivity of the barcode scanner 6 and the characteristics of the noise filter are changed to match the barcode reading from the mobile phone 8.

  The operator places the barcode scanner 6 on the barcode display surface of the mobile phone 8 held by the client. When the barcode of the mobile phone 8 is correctly read, the process proceeds to the proxy storage process as it is.

  However, when the bar code of the mobile phone 8 cannot be read correctly, unread is displayed on the liquid crystal display 3 to notify the operator that the bar code has not been read. At this time, the simulated bar code 3a having the same code system as the read bar code is displayed on the liquid crystal display 3.

  As a result, the operator performs an operation of reading the barcode by placing the barcode scanner 6 against the simulated barcode 3 a displayed on the liquid crystal display 3. If the simulated bar code 3a can be read correctly, the operator can determine that the display 8a of the mobile phone 8 has an abnormality such as dirt and cannot be read. If the simulated barcode 3a cannot be read correctly, the operator can determine that the barcode scanner 6 has some abnormality and cannot be read.

  As described above, when the bar code displayed on the display 8a of the mobile phone 8 cannot be read by the bar code scanner 6 in the charge agent storage mode, the POS terminal device 1 is on the mobile phone 8 side. It is possible to notify the operator by accurately determining whether it is on the barcode scanner 6 side.

  In this embodiment, in the charge substitution storage mode, a mode change command is transmitted from the CPU 11 to the barcode scanner 6 to increase the sensor sensitivity, and the characteristic of the noise removal filter 64 is changed to that of the barcode from the mobile phone 8. However, the present invention is not necessarily limited to this. As shown in FIG. 1, a setting changeover switch 6a is provided on the side of the barcode scanner 6, and the setting changeover switch 6a is operated. The sensor sensitivity may be increased, and the characteristics of the noise removal filter 64 may be changed.

In this embodiment, the sensor sensitivity and the noise removal filter characteristics are usually set to optimum values for reading a barcode printed on a product, and the barcode displayed on the mobile phone is read. In some cases, the sensor sensitivity and the characteristics of the noise removal filter are switched. However, the present invention is not necessarily limited to this, and conversely, the sensor sensitivity and the characteristics of the noise removal filter are usually displayed on the mobile phone. The sensor sensitivity and the noise removal filter characteristics may be switched when reading a barcode printed on a product.
In this embodiment, the present invention is applied to a POS terminal device. However, the present invention is not limited to this, and can be applied to an electronic scale and other settlement systems.
