Also, the mode switch 24 and the drawer opening device 25 are connected to the I / O 15, the LAN 2 is connected to the network controller 16, the display for customer is connected to the display controller 19, the scanner 27 is connected to the scanner interface 21, and the HDD An HDD 28 is connected to the controller 22.

  Further, USB 2.0 interfaces 29 to 31 are connected to the USB 2.0 controller 23, a keyboard 32 is connected to the USB 2.0 interface 29, a hand scanner 33 is connected to the USB 2.0 interface 30, and USB 2. A printer 34 is connected to the 0 interface 31. That is, the keyboard 32, the hand scanner 33, and the printer 34, which are peripheral devices, are connected via the USB 2.0 interfaces 29 to 31, respectively. Since the keyboard 32, hand scanner 33, and printer 34 are connected via USB 2.0 interfaces 29 to 31, respectively, the keyboard 32, hand scanner 33, and printer 34 can be plug and play.

  The CPU 11 comprehensively controls the POS terminal 1 by executing control programs stored in the ROM 12 and the HDD 28. The ROM 12 stores a control program for performing basic operations. The RAM 13 is formed with a work area and the like necessary when the CPU 11 executes the control program. The clock unit 14 measures time and generates date / time information. The I / O 15 notifies the CPU 11 of the mode change from the mode switch 24. Further, the I / O 15 transmits an instruction for opening the drawer from the CPU 11 to the drawer opening device 25.

  The network controller 16 controls data communication with the store computer 3 via the LAN 2. The keyboard controller 17 performs control to transmit key information input from the keyboard 32 acquired via the USB 2.0 interface 29 to the CPU 11. The touch panel controller 18 controls to transmit a signal from a touch panel (not shown) to the CPU 1131. The touch panel controller 18 controls display on a touch panel (not shown) based on an instruction from the CPU 11. The display controller 19 controls display on the display 26 based on an instruction from the CPU 11. The printer controller 20 controls printing of the printer 34 that prints journals and receipts via the USB 2.0 interface 31.

  The scanner interface 21 controls the input of barcode data read by the scanner 27. The HDD controller 22 controls the storage of information on the hard disk in the HDD 28 and the reading of information stored from the hard disk. In the hard disk, a control program for executing an operation system for operating the POS terminal 1, a peripheral device list L1 (storage means) indicating peripheral devices connected to the USB 2.0 interfaces 29 to 31, and an activation to be described later Peripheral device recognition programs that are sometimes executed are stored. The operation system described above is compatible with plug and play.

  FIG. 3 is a diagram showing the peripheral device list L1. As described above, since the keyboard 32, hand scanner 33, and printer 34 are connected to the USB 2.0 interfaces 29 to 31, the keyboard 32, hand scanner 33, and printer 34 are registered in the peripheral device list L1. That is, the hand scanner 33 (8a6, 36, HS-560) is connected to USB1 (USB2.0 interface 30), the printer 34 (8a6, b, Printer) is connected to USB2 (USB2.0 interface 31), and USB3 (USB2.0 is connected). A keyboard 32 (8ab, c, KB) is registered in the interface 29).

  Next, peripheral device recognition processing executed when the POS terminal 1 is started will be described. FIG. 4 is a flowchart showing a main part of the peripheral device recognition process executed by the CPU 11.

  When a power supply (not shown) is turned on to the POS terminal 1, the CPU 11 starts a peripheral device recognition program (USBCHK.exe) for recognizing peripheral devices connected to the USB 2.0 interfaces 29 to 31 (S1). Then, the CPU 11 acquires a list of peripheral devices registered in the peripheral device list L1 (S2, acquisition means). Information indicating the list of peripheral devices acquired in this way is stored in a predetermined area of the RAM 13.

  Next, the CPU 11 searches for peripheral devices connected to the USB 2.0 interfaces 29 to 31 (S3, search means). Information indicating the peripheral device searched in this way is stored in a predetermined area of the RAM 13. Then, the CPU 11 determines whether or not all peripheral devices have been recognized (S4, determination means). Specifically, the determination is made by comparing the peripheral device acquired from the peripheral device list L1 stored in the predetermined area of the RAM 13 with the searched peripheral device stored in the predetermined area of the RAM 13.

  When the peripheral device acquired from the peripheral device list L1 stored in the predetermined area of the RAM 13 does not match the searched peripheral device stored in the predetermined area of the RAM 13, that is, the peripheral device acquired from the peripheral device list L1 If there is a peripheral device that has not been searched for (NO in S4), the CPU 11 performs the process of recognizing peripheral devices connected to the USB 2.0 interfaces 29 to 31 continuously. For example, it is determined whether or not (three times) (S5).

  If the predetermined number of times has not been reached (NO in S5), the CPU 11 deletes the driver that recognizes the peripheral device that is not the searched peripheral device among the peripheral devices acquired from the peripheral device list L1 (S6, deletion means). Then, the CPU 11 reloads the peripheral device driver (S7, reload means). Then, returning to the process of step S1, the CPU 11 activates the peripheral device recognition program again and repeats the above-described process.

  On the other hand, when the CPU 11 determines that the number of times is the predetermined number (YES in S5), it displays an error on the display 26 (S8). In place of the process of displaying an error on the display 26, the process may not proceed to the next process, that is, the application software stored in the HDD 28 may not be activated.

  When the CPU 11 performs an error display (S8), it is determined that the peripheral device acquired from the peripheral device list L1 stored in the predetermined area of the RAM 13 matches the searched peripheral device stored in the predetermined area of the RAM 13. If so (YES in S4), this process ends. When the process is ended, the CPU 11 clears the information indicating the peripheral device acquired from the peripheral device list L1 stored in the predetermined area of the RAM 13 and the information indicating the searched peripheral device stored in the predetermined area of the RAM 13.

  Next, the operation will be described. When the power switch of the POS terminal 1 to which the keyboard 32, hand scanner 33, and printer 34 are connected is turned on via the USB 2.0 interface 29 to 31, and the power is turned on, the keyboard registered as a peripheral device 32, the hand scanner 33, the printer 34, and the peripheral devices that are connected to the USB 2.0 interfaces 29 to 31 at the time of activation and are recognized.

  If the recognized peripheral devices are the keyboard 32, hand scanner 33, and printer 34, application software is activated. As a result, the normal operation of the POS terminal 1 can be executed.

  On the other hand, when the recognized peripheral devices are, for example, the hand scanner 33 and the printer 34, that is, when the keyboard 32 cannot be recognized, the driver for recognizing the keyboard 32 is deleted and reloaded. . Then, again, the keyboard 32, hand scanner 33, and printer 34 registered as peripheral devices are compared with the peripheral devices that are connected to and recognized by the USB 2.0 interfaces 29 to 31 at the time of activation.

  If the peripheral devices recognized again are the keyboard 32, the hand scanner 33, and the printer 34, application software is activated. As a result, the normal operation of the POS terminal 1 can be executed.

  After deleting the peripheral device driver that is not recognized in this manner, the processing for performing the recognition of the peripheral device again after the reloading is executed until a predetermined number of times. If there is a peripheral device that cannot be recognized even after the predetermined number of times, an error is displayed on the display 26.

  Therefore, according to this embodiment, at the time of activation, the POS terminal 1 deletes a peripheral device driver that is not recognized among peripheral devices connected to the USB 2.0 interfaces 29 to 31 and reloads the peripheral device again. Performs recognition processing. By performing this processing, recognition errors of the keyboard 32, hand scanner 33, and printer 34, which are peripheral devices, can be prevented, and the peripheral devices can be recognized stably. Therefore, the worker does not have to perform the work of reconnecting the peripheral device to the USB 2.0 interfaces 29 to 31 or the restart of the POS terminal 1.

  Further, when all the peripheral devices registered in the peripheral device list L1 cannot be recognized when the POS terminal 1 is started up, a specific peripheral device such as the keyboard 32 is connected to the USB 2.0 by not starting the application software. By removing from the interface 29, the POS terminal 1 can be disabled. That is, the peripheral device can be used as a key for starting the POS terminal 1. That is, it can be used as security that does not activate the system of the POS terminal 1 unless a specific peripheral device is connected.

  In the above-described embodiment, the USB 2.0 interface is used as an interface for connecting peripheral devices. However, the present invention is not limited to this, and any interface corresponding to plug and play may be used.

  Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying constituent elements without departing from the scope of the invention in the implementation stage.
