A printer 14 for printing, a cash drawer 15 and the like are provided. Various devices such as a bar code scanner for reading bar code information and a card reader for reading a magnetic card are usually connected to the POS terminal device. In order to clarify the features of the present invention, FIG. 1 to FIG. Is not shown. 1 to 3 show an example in which a keyboard is used as an input device, a configuration including an input device other than a keyboard, such as a touch panel, may be used.

  The input device 12 such as a keyboard (hereinafter simply referred to as “input device 12” unless otherwise required) includes a lock unit 23. The lock unit 23 sets and releases the lock mode by inserting the lock key 24 into the key hole 25 and rotating it to a predetermined position. Further, the host device 11 includes a power supply unit 37, and supplies power from the power supply unit 37 to the input device 12, the display device 13, and other devices.

  The checkout processing device 10 performs checkout processing for purchased products based on reading input by a bar code scanner (not shown) or input from the input device 12. Input information from a keyboard, a scanner, or the like is transmitted to the host device 11, and a purchase amount, a settlement amount, etc. are calculated in the host device 11. Purchase information and checkout information are transmitted from the host device 11 to various display devices 13 including a customer display. These data are also transmitted from the host device 11 to the printer 14, and a receipt printed with the details of the purchased product, the payment amount, etc. is issued. When the settlement amount is confirmed and the operator receives money, the cash drawer 15 can be opened and closed, and cash is exchanged with the customer. In addition, from the viewpoint of erroneous operation and crime prevention, when the operator leaves the payment processing apparatus 10, the lock key 24 is used to prevent input of the payment processing apparatus.

  FIG. 2 shows a connection form of the host device 11 and the input device 12 and other peripheral devices 13 to 15. The host device 11 includes a CPU 30 that is a central control device, a memory 35 that stores control programs, control data, and the like, a power supply unit 37 that supplies power to the host device 11 and external devices, a power switch 36, and external devices The first bridge 31, the second bridge 32, and the I / O control IC 33 constituting the interface are provided. The first bridge 31, the second bridge 32, and the I / O control IC 33 are also referred to as a north bridge, a south bridge, and a super I / O, respectively. The CPU 30 and the first bridge 31, the second bridge 32, the I / O control IC 33, and the memory 35 are connected by an internal bus. The CPU 30 operates at a constant speed based on an operation clock output from an oscillation circuit (not shown). The above connection form is an example, and a connection form having a first bridge, a second bridge, an I / O control IC, etc. in one CPU chip is also included in the present invention.

  In the example of FIG. 2, the display device 13 including the touch panel 16 is connected to the host device 11 via the first bridge 31. The input device 12 is connected via the second bridge 32, and the printer 14 and the cash drawer 15 are connected via the I / O control IC 33.

  The input device 12 includes an input key 21 corresponding to each character, number, and the like, and a controller 22 that transmits data corresponding to the pressed input key 21 to the host device. The input device 12 further includes a lock unit 23, and a lock control unit 26 is provided in the controller 22. The lock unit 23 outputs a lock signal to the lock control unit 26 of the controller 22 by inserting the lock key 24 into the key hole 25 and rotating to the lock position. When receiving the lock signal, the lock control unit 26 prohibits transmission of input data from the controller to the host device 11 and transmits a lock signal to the host device 11. Thereby, subsequent key input is prohibited.

  FIG. 3 is a functional block diagram illustrating a part of the functions of the host device 11 illustrated in FIGS. 1 and 2. The interface 41 includes the first bridge 31, the second bridge 32, and the I / O control IC 33 shown in FIG. 2, and includes a main control unit 42, a settlement processing unit 43, an input control unit 44, a display control unit 45, and a print control unit. 46, the power management means 47, the CPU 30 of FIG. 2, the memory 35, and a control program, control data, etc. stored in the memory.

  Each function of the host device 11 will be described along functional blocks shown in FIG. The settlement processing unit 43 acquires data such as the price and number of products purchased by the customer based on the input data, and executes the settlement process. The input control means 44 controls input operations of the input device 12, the touch panel 16, and an input device such as a barcode scanner (not shown). The display control means 45 controls the display device 13 such as an operator display unit and a customer display, and displays the settlement information in the settlement process, the settlement result, and the like on the display unit. The print control unit 46 controls the printer 14 to execute receipt printing, slip printing, and the like. The power management means 47 manages the power supplied through the power supply unit 37 and suppresses unnecessary power consumption in the lock mode (in this specification, the power saving state in such a lock mode is referred to as “power saving mode”). Called). In addition, the power management means can be configured to suppress power consumption by reducing the frequency of the CPU operating clock when the settlement processor is not used for a predetermined time, regardless of the lock mode (such a lock mode). A power saving state other than the mode is referred to as “sleep mode”).

  In the above embodiment, an example in which the lock unit 23 and the lock control unit 26 are provided in the input device 12 has been described. However, a configuration in which the host device 11 or the display device 13 and the printer 14 are provided in a peripheral device is also possible. It is. Furthermore, it is possible to provide only the lock unit 23 in the input device 12 so that the host device 11 does not accept input data. That is, in this configuration, even if the input device 12 transmits input data to the host device 11 via the controller 22, the input control means 41 of the host device 11 operates so as not to accept the input data.

  The power switch 36 is a switch that can be physically operated to turn on or off the payment processing apparatus 10. By turning on this switch, the power supply unit 37 is activated. The host device 11, the input device 12, the display device 13, and the like may be configured to be supplied with power from the power supply unit 37, or may be configured so that each device has its own power supply unit.

  The input device 12, the display device 13, the touch panel 16, and the printer 14 are connected to the host device 11 via the interface 41. In FIG. 3, the touch panel 16 is separated from the display device 13 for easy understanding of the function. A special function of the touch panel 16 in the present invention will be described later.

<Function and operation of checkout processing device>
A settlement process that is a basic function of the settlement processing apparatus 10 will be described. When the purchased product data is input to the host device 11 by the operator, the settlement processing unit 43 executes the settlement processing for the purchased product. At the same time, under the control of the display control means 45, the price of the purchased product, the accumulated price of the purchased product, and the like are sequentially displayed on the display device 13. When the data input for all purchased products is completed, a receipt on which the product name, unit price, purchased quantity, total amount, etc. of the purchased product are printed is issued from the printer 14 based on the control of the print control means 46.

  The settlement processing apparatus 10 performs the settlement processing operation as described above as its main part. However, when the operator leaves the checkout processing apparatus, such as when the operator changes, the operator operates the lock key 24 to set the checkout processing apparatus 10 to the lock mode.

  When the lock mode is entered, data cannot be input to the checkout processing apparatus 10 as described above. Furthermore, the power management means 47 shifts to the power saving mode by receiving the lock signal. The power saving mode according to the present invention may be in the same state as the sleep mode described above, but may have a special power saving configuration different from the sleep mode. For example, the operation clock of the CPU 30 is set to a low speed and the power of the power saving mode according to the installation environment and the operation environment of the checkout processing apparatus 10 such as turning off the power of the display device 13, the input device 12, the touch panel 16, the printer 14 and the like Configuration is possible.

  The lock mode is set on the assumption that the checkout processing apparatus 10 is not used until the lock mode is released. Therefore, during the lock mode period, the settlement processor 10 is in an operation stop state unless an emergency occurs. Therefore, the power consumed by the checkout processing apparatus during this period is wasted. In order to avoid this situation, it is conceivable to turn off the power supply of the entire payment processing apparatus 10. However, when the power is turned off, the predetermined data such as the initial setting data is also cleared, and it is not preferable for the history management of the settlement processor to repeatedly turn the power on and off several times a day. Another problem is that the self-diagnosis program starts each time the power is turned on and takes time to start up. Therefore, when it is certain that the settlement processing apparatus 10 is not operated for a certain period of time, such as when the operator temporarily leaves the settlement processing apparatus, the function of prohibiting the input of the settlement processing apparatus 10 and setting the lock mode is useful. .

  Therefore, the present invention is configured to suppress wasteful power consumption by providing a power saving function as well as a function of locking an input when shifting to the lock mode. That is, at the time of shifting to the lock mode, it is configured to supply only the minimum necessary power, thereby suppressing unnecessary power consumption. The minimum necessary power is, for example, power for monitoring the lock signal and the lock release signal, power for returning to a state in which normal operation can be performed when the lock release signal is received, and the like.

  FIG. 4 illustrates a functional block diagram of the power management unit 47 according to the embodiment of the present invention. Although it is possible to provide the power management means 47 with a function for shifting to the sleep mode, in FIG. 4, in order to clarify the characteristics of the present invention, the power management means 47 is accompanied by the shift to the lock mode which is a characteristic part of the present invention. Only the power saving mode functions are shown.

  The power management unit 47 includes a signal monitoring unit 51, a power saving transition control unit 52, a power recovery processing unit 53, an emergency recovery processing unit 54, a power saving processing unit 55, a power recovery processing unit 56, and a touch panel power supply unit 57. ing. The signal monitoring unit 51 monitors a lock signal output from the lock unit 23 when the lock key 24 is in the lock position and a lock release signal output when the lock key 24 moves to a position other than the lock position. It is also possible to configure so that when the lock signal is not output, it is recognized as a lock release signal.

<Transition to power saving mode and release operation of lock mode>
When the signal monitoring unit 51 detects the output of the lock signal, the power saving transition control unit 52 is activated. The power saving transition control unit 52 controls the processing operation of the power saving processing unit 55. For example, the power saving processing unit 55 switches the operation clock of the CPU 30 to an operation clock having a lower frequency than the normal operation clock. In addition, unnecessary power supply to devices that are not used in the lock mode among the host device 11, the input device 12, the display device 13, the printer 14, and the like is stopped or limited. Thereby, it is possible to maintain the monitoring function and the return function of the power management means, supply power for holding predetermined data, and stop other power.

  At this time, it is desirable not to immediately stop the power supply for a certain device when shifting to the lock mode. For example, for devices that require a certain amount of time after power-on, such as inkjet printers, when the power is turned on, the power is not turned off even when the lock mode is entered, or a lock signal is received It is desirable that the power is turned off after a predetermined time has passed. The power saving transition control unit 52 controls the processing operation for shifting to such a power saving mode.

  When the signal monitoring unit 51 receives the lock release signal, the power recovery control unit 53 is activated. The power recovery control unit 53 controls the power recovery processing unit 56 to return the operation clock of the CPU 30 to the normal operation clock, and supplies power to each unit that has been stopped. As a result, the checkout processing apparatus 10 returns from the power saving mode to the normal operation mode in which normal power is supplied.

  The emergency return control unit 54 is a means for releasing the lock by a method other than the lock key. For example, when the operator in charge is unknown while holding the lock key, when another operator needs to use the settlement processing measure 10, or when the lock key 24 is lost, the lock key 24 A return method that does not use is required. Also, if the device (in this embodiment, the input device 12) in which the lock unit 23 is provided in the lock mode is removed from the host device for maintenance or repair reasons, the lock key 24 is not used. What is needed is a way to unlock the lock mode.

  In preparation for such a situation, the power management means 47 shown in FIG. 4 is provided with an emergency return control unit 54 so that the lock mode can be released without using the lock key 24. When the power switch 36 is pressed in the lock mode state to detect a power-on signal (power switch ON signal), the emergency return control unit 54 controls the touch panel power supply unit 57 to supply power to the touch panel 16 first.

  FIG. 5 shows an example when the power of the touch panel 16 is turned on in the lock mode state. As shown in FIG. 5, a predetermined touch key 17 is displayed on the touch panel portion on the display device 13. In FIG. 5, four touch keys 17 of A, B, C, and D are displayed, but numbers and other symbols may be used, and the number of touch keys 17 to be displayed can be arbitrarily set. The operator uses these touch keys 17 to input a password for releasing the lock mode. The password is composed of a combination of predetermined touch keys 17 and is determined in advance. For example, it is possible to set a complicated combination such as inputting A twice, D once, B five times, and A once (AADBBBBBBA) as a password.

  In order to make the operation easier, for example, one touch key 17 is displayed, and the lock mode is canceled by pressing the displayed touch key 17 five times continuously at a predetermined time interval. It is also good. Moreover, the structure which uses the operation | movement which touches predetermined positions, such as the lower right of the touch panel 16 and the center, a predetermined number of times as a password is also possible. Since the display device 13 may not display in the power saving mode, it is preferable to adopt this configuration.

  When the password is correctly input and the emergency return control unit 54 verifies this, the emergency return control unit 54 outputs the same signal as the unlock signal to the power return control unit 53. Accordingly, the power return control unit 53 releases the lock mode state and the power saving mode, and returns the settlement processing apparatus 10 to the normal operation mode.

<Transition procedure to lock mode>
An example of the processing procedure for shifting to the lock mode will be described with reference to the flowchart of FIG. The transition process to the lock mode is started based on a lock signal output when the lock key 24 is moved to the lock position. Therefore, the lock control unit 26 monitors the lock signal (S101). When the lock key 24 is moved to the lock position, a lock signal is output. When receiving the lock signal (S101; Yes), the lock control unit 26 prohibits data input by the input key 21 (S102). The prohibition of data input is based on a control signal from the lock control unit 26 so that input data is not transmitted from the controller 22 of the input device 12 to the host device 11, or the input / output control means 44 of the host device 11 This can be realized by not accepting input data.

  Next, the power management unit 47 shifts to the power saving mode based on the lock signal (S103), and stops or restricts the supply of unnecessary power. For example, the supply of unnecessary power to each device 12, 13, 14, etc. connected to the host device 11 or each part in the host device is stopped, and the CPU 30 is switched to a low-speed operation clock. In addition, a configuration in which the supply of power is stopped or limited after a certain period of time for a predetermined peripheral device connected or the like is possible.

<Unlock processing procedure>
An example of the lock mode release processing procedure will be described with reference to the flowchart of FIG. The lock mode release processing is executed by receiving a lock release signal in principle. The flowchart of FIG. 7 further illustrates a processing procedure that enables unlocking using the touch panel in an emergency. The unlocking process, that is, the process of canceling the lock mode and returning to the normal operation mode mainly includes a process of restoring power and a process of canceling the prohibition of data input.

  In the lock mode state, it is monitored whether or not an unlock signal has been received (S201). When the unlock signal is received (S201; Yes), the power that has been stopped is first supplied to each unit for normal operation. The mode is restored (S205). Next, the prohibition of data input is canceled and data input can be accepted (S206).

  If an unlock signal has not been received (S201; No), it is further confirmed whether a power switch ON signal has been received (S202). If the power switch ON signal has not been received (S202; No), the monitoring process of the lock release signal and the power switch ON signal is repeated (S201, 202). When the power switch ON signal is received in the lock mode (S202; Yes), power is supplied to the touch panel 16 and input from the touch key 17 is received (S203). When a password is input by operating the touch key 17, it is verified whether the password is correct (S204). If the passwords are different (S204; No), the confirmation process is repeated. If the password is verified (S204; Yes), the power is restored (S205) and data input is accepted (S206), as in the case of receiving the unlock signal.

  In the processing steps S203 and S204, if the input password does not match the predetermined number of times, the cancellation process by the touch panel may be stopped and a voice or other alarm may be generated (not shown).

  In the above embodiment, the lock unit 24 and the lock control unit 26 are provided on the keyboard (input device 12). However, the lock unit 24 and the lock control unit 26 are the host device 11, the printer 14, and the display device. 13. It can also be provided in other devices. In that case, it is desirable that the prohibition of input from the input device 12 such as a keyboard is controlled by the input control means of the host device 11.

  In the above description, the mechanical key (key) type lock key 24 is physically rotated to output a lock signal and an unlock signal. However, as the lock key 24, a magnetic card or an IC card is used. It is also possible to use it. A configuration may be adopted in which predetermined data is read from a magnetic card or an IC card to shift to the lock mode or release the lock mode. Furthermore, it is possible to enter a predetermined password and shift to the lock mode without using the lock key 24. Further, a part of the touch keys 17 may be made usable even in the lock mode so that a password can be input immediately in an emergency.
