For this reason, the conventional self-order terminal is normally connected to a charger, and when a customer turns and looks at the self-order terminal in a passenger seat, it is required to operate with a battery.

  Conventional self-order terminals use mechanical switches as power switches. For example, there is a self-order terminal that uses, as a power switch, an open / close mechanical switch that can cut off a power supply voltage and a power supply current. There is also a self-order terminal that accepts a power ON trigger signal from a mechanical switch and executes power OFF with software.

  When the power switch is hidden by the cover, it is possible to prevent erroneous operations such as tampering by the customer. However, the store clerk (user) has the disadvantage of having to operate the power switch after removing the cover.

  Further, when the operation of the self-order terminal is controlled by attaching and detaching the battery, a problem arises that the store clerk (user) must manage the battery.

  According to the above invention, the order receiving terminal device receives the charging voltage when connected to the charger. When detecting the charging voltage supplied from the charger, the order receiving terminal device transforms the voltage of the battery to a predetermined voltage and supplies the predetermined voltage to the processing circuit. When a predetermined voltage is supplied, the processing circuit executes processing for receiving an order. Therefore, the detection of the charging voltage becomes a trigger for starting the operation of the processing circuit.

  For this reason, it is possible to eliminate the need for a power switch for a mechanical mechanism that has conventionally created a trigger for starting a process for receiving an order. Further, unlike the prior art, it is not necessary to manage the battery removed from the order receiving terminal device. Therefore, it is possible to prevent the user's inconvenience due to the presence of the power switch of the mechanical mechanism and the user's inconvenience due to managing the battery.

  When the detection circuit detects the charging voltage, the detection circuit provides a charge monitoring signal to the power supply control circuit, and when the processing circuit receives the predetermined voltage, the power supply control circuit receives a power supply lock signal. When the power supply control circuit receives at least one of the charge monitoring signal and the power supply lock signal, the power supply control circuit transforms the voltage of the battery to the predetermined voltage, and converts the predetermined voltage to the predetermined voltage. It is desirable to supply the processing circuit.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to prevent the trouble of the user of an order reception terminal device.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing an order receiving system according to an embodiment of the present invention. This order reception system is provided in each table of a restaurant such as a pub or a restaurant, and receives an order input by a customer who comes to the meal.

  In FIG. 1, the order reception system includes an order reception terminal device 1 and a charger 2.

  The order receiving terminal device 1 uses the battery 3 as a power source and receives an order input from a user.

  The charger 2 is detachable from the order receiving terminal device 1, and when connected to the order receiving terminal device 1, supplies a charging voltage to the order receiving terminal device 1 to charge the battery 3.

  The order receiving terminal device 1 includes a battery 3, a charging terminal 4, a charging circuit 5, a power supply control circuit 6, a main circuit 7, an input / output device 8, and a communication interface 9. The power supply control circuit 6 includes an OR circuit 6a and a power supply circuit 6b.

  The battery 3 is a chargeable / dischargeable secondary battery.

  The charging terminal 4 receives the charging voltage supplied from the charger 2 when the order receiving terminal device 1 is connected to the charger 2.

  The charging circuit 5 is an example of a detection circuit, and detects the charging voltage supplied from the charger 2.

  Specifically, the charging circuit 5 indicates that the voltage of the charging terminal 4 is equal to or higher than a specific voltage (for example, the specific voltage is a predetermined charging voltage value). When the charging voltage is received from the charger 2, a charge monitoring signal indicating that the charging voltage has been detected is provided to the power supply control circuit 6 (specifically, the OR circuit 6a).

  The charging circuit 5 charges the battery 3 using the charging voltage received by the charging terminal 4 when the voltage at the charging terminal 4 is equal to or higher than the specific voltage.

  The charging circuit 5 uses a standby power source (not shown) different from that of the battery 3 as a power source, and is always supplied with power.

  When the charging circuit 5 detects the charging voltage, the power supply control circuit 6 transforms the voltage of the battery 3 to a predetermined voltage and supplies the predetermined voltage to the main circuit 7. For example, when receiving a charge monitoring signal, the power supply control circuit 6 transforms the voltage of the battery 3 to a predetermined voltage and supplies the predetermined voltage to the main circuit 7. The predetermined voltage is a voltage at which the main circuit 7 can operate.

  The main circuit 7 is a circuit such as a CPU that controls the input / output device 8 and the communication interface 9.

  The main circuit 7 is an example of a processing circuit, and executes processing for receiving an order when a predetermined voltage is supplied. For example, when a predetermined voltage is supplied, the main circuit 7 receives an order input by the user of the order receiving terminal device 1 (specifically, a customer at the store) from the input / output device 8 and receives the order. Processing to transmit from the communication interface 9 to a host (not shown) can be executed.

  Further, when the main circuit 7 receives a predetermined voltage, the main circuit 7 starts to provide a power supply lock signal to the power supply control circuit 6 (specifically, the OR circuit 6a).

  When receiving the power lock signal, the power supply control circuit 6 transforms the voltage of the battery 3 to a predetermined voltage and supplies the predetermined voltage to the main circuit 7.

  The OR circuit 6 a receives a charge monitoring signal from the charging circuit 5 and receives a power lock signal from the main circuit 7. The OR circuit 6a provides a power control signal to the power circuit 6b when at least one of the charge monitoring signal and the power lock signal is received.

  The OR circuit 6a uses a standby power source (not shown) different from that of the battery 3 as a power source, and is always supplied with power.

  The power supply circuit 6b is, for example, a regulator IC that receives an enable signal. The power supply circuit 6b uses the power supply control signal from the OR circuit 6a as an enable signal. When receiving the power control signal from the OR circuit 6a, the power supply circuit 6b transforms the voltage of the battery 3 to a predetermined voltage and supplies the predetermined voltage to the main circuit 7.

  For example, when the main circuit 7 receives a power-off instruction from the input / output device 8 together with a password known only to the store clerk, the main circuit 7 stops the power lock signal. This prevents a customer who does not know the password from stopping the power lock signal.

  The OR circuit 6a provides a power control signal to the power circuit 6b when at least one of the charge monitoring signal and the power lock signal is received. For this reason, even if the power lock signal is stopped, if a charge monitoring signal exists, the OR circuit 6a outputs a power control signal.

  Therefore, in the present embodiment, when the charging terminal 4 receives the charging voltage from the charger 2 so that the probability that the main circuit 7 stops the operation increases with the stop of the power supply lock signal. The charge monitoring signal is output for a certain time. For example, the charging circuit 5 uses a one-shot circuit to generate a charge monitoring signal having a certain time width.

  For this reason, even if the order reception terminal device 1 continues to be connected to the charger 2, the charge monitoring signal stops after a certain period of time has elapsed since the charging monitoring signal was output. Accordingly, when the power lock signal is stopped while the charge monitoring signal is stopped, the operation of the main circuit 7 is stopped as the power lock signal is stopped.

  The input / output device 8 is controlled by the main circuit 7 to display a store menu, and accepts an order input by a user of the order receiving terminal device 1 (specifically, a customer of the store) and receives it. The new order is provided to the main circuit 7.

  The communication interface 9 is controlled by the main circuit 7 and transmits an order received by the input / output device 8 to a host (not shown).

  Next, the operation will be described.

  FIG. 2 is a time chart for explaining the power supply control operation of the order receiving terminal device 1. Hereinafter, the power control operation of the order receiving terminal device 1 will be described with reference to FIG.

  In FIG. 2, when the order receiving terminal device 1 is connected to the charger 2 in a situation where a predetermined voltage is not supplied to the main circuit 7 (also referred to as “power OFF”), the charging terminal 4 is connected to the charger. The charging voltage is received from 2 (T1: charger is mounted).

  When the charging terminal 4 receives the charging voltage from the charger 2, the charging circuit 5 provides a charge monitoring signal to the OR circuit 6a for a certain time. The OR circuit 6a provides a power supply control signal to the power supply circuit 6b while receiving the charge monitoring signal. When receiving the power supply control signal, the power supply circuit 6b transforms the voltage of the battery 3 to a predetermined voltage and supplies the predetermined voltage to the main circuit 7 (T2: power supply ON).

  When receiving a predetermined voltage, the main circuit 7 executes processing for receiving an order and starts to provide a power lock signal to the OR circuit 6a (T3).

  In a situation where the OR circuit 6a accepts the power lock signal, even if the order receiving terminal device 1 is disconnected from the charger 2, the OR circuit 6a continues to provide the power control signal to the power circuit 6b. The circuit 7 continues to operate (T4: charger release to T5: charger attachment).

  When the operation of the main circuit 7 is stopped, the store clerk inputs a power OFF instruction to the input / output device 8 together with a password unknown to the customer. When the main circuit 7 receives a power OFF instruction together with the password from the input / output device 8, the main circuit 7 stops the power lock signal. When the power lock signal stops, the OR circuit 6a stops the power control signal. At this time, it is assumed that the charge monitoring signal is stopped. For this reason, the power supply circuit 6b stops supplying a predetermined voltage to the main circuit 7 (T6: power supply OFF).

  According to the present embodiment, the order receiving terminal device 1 controls the power ON of the main circuit 7 without including a power switch that is a mechanical switch.

  Specifically, when the charging terminal 4 is connected to the charger 2, the charging terminal 4 receives a charging voltage. When the charging circuit 5 detects the charging voltage, the power supply control circuit 6 transforms the voltage of the battery 3 to a predetermined voltage and supplies the predetermined voltage to the main circuit 7. When a predetermined voltage is supplied, the main circuit 7 executes processing for receiving an order. Therefore, the detection of the charging voltage becomes a trigger for starting the operation of the main circuit 7.

  For this reason, it is possible to eliminate the need for a power switch for a mechanical mechanism that has conventionally created a trigger for starting a process for receiving an order. Further, unlike the prior art, it is not necessary to manage the battery removed from the order receiving terminal device. Therefore, it is possible to prevent the user's inconvenience due to the presence of the mechanical switch power switch and the user's inconvenience due to managing the battery.

  In the present embodiment, when the charging circuit 5 detects the charging voltage, the charging circuit 5 provides a charge monitoring signal to the power supply control circuit 6. When the main circuit 7 receives the predetermined voltage, the charging circuit 5 The power supply control circuit 6 starts to provide the power supply lock signal, and at least one of the charge monitoring signal and the power supply lock signal is received, the battery voltage is transformed to a predetermined voltage, and the predetermined voltage is supplied to the main circuit. 7 is supplied.

  In this case, even if the order receiving terminal device 1 is separated from the charger 2 after a predetermined voltage is supplied to the main circuit 7, if the main circuit 7 provides a power lock signal to the power control circuit 6, the main It is possible to prevent the processing of the circuit 7 from stopping. For this reason, the customer can use the order receiving terminal device 1 in which the main circuit 7 is operating in a state separated from the charger 2.

  In the above embodiment, the charging circuit 5 in the order receiving terminal device 1 generates a charging monitoring signal when the charging voltage is detected, and provides the charging monitoring signal to the power supply control circuit 6. When the device 2 detects whether or not the charging voltage has been supplied to the order receiving terminal device 1 and detects that the charging voltage has been supplied to the order receiving terminal device 1, the charging monitor signal is sent to the order receiving terminal device 1. The power supply control circuit 6 may be provided.

The order receiving terminal 1A includes a battery 3, a charging terminal 4, a charging circuit 5a, a power supply control circuit 6, a main circuit 7, an input / output device 8, a communication interface 9, and a communication terminal 10. .

  When the voltage at the charging terminal 4 is equal to or higher than the specific voltage, the charging circuit 5a charges the battery 3 using the charging voltage received by the charging terminal 4.

  The charging voltage generation circuit 2a generates a charging voltage.

  The charging terminal 2 b is connected to the charging terminal 4 when the order receiving terminal device 1 A is attached to the charger 2 A, and supplies the charging voltage generated by the charging voltage generation circuit 2 a to the charging terminal 4.

  The communication terminal 2c is connected to the communication terminal 10 when the order receiving terminal device 1A is attached to the charger 2A. The communication terminal 10 is connected to the power supply control circuit 6 (specifically, the OR circuit 6a).

  When detecting that the charging voltage is supplied to the order receiving terminal device 1A, the detection circuit 2d provides a charge monitoring signal to the order receiving terminal device 1A.

  The charging current detection circuit 2 d 1 is an example of a charging detection circuit, and detects the presence or absence of a charging current that flows when the charging terminal 2 d is connected to the charging terminal 4. When the charging current detection circuit 2d1 detects the charging current, that is, detects that the charging voltage is supplied to the order receiving terminal device 1A, the charging current detection circuit 2d1 provides a detection signal to the charging monitoring signal generation circuit 2d2.

  The charge monitoring signal generation circuit 2d2 is an example of a signal generation circuit. When the detection signal is received from the charging current detection circuit 2d1, the charge monitoring signal generation circuit 2d2 provides the charge monitoring signal to the communication terminal 2c. At this time, since the communication terminal 2c is connected to the communication terminal 10, the charge monitoring signal is transmitted through the communication terminal 2c and the communication terminal 10 to the power supply control circuit 6 (specifically, the OR circuit 6a). ) Provided.

  According to the present embodiment, the charger 2A supplies a charging voltage to the order receiving terminal device 1A when connected to the order receiving terminal device 1A. When detecting that the charging voltage is supplied to the order receiving terminal device 1A, the detection circuit 2d provides a charge monitoring signal to the order receiving terminal device 1A.

  When receiving the charge monitoring signal, the power supply control circuit 6 transforms the voltage of the battery 3 to a predetermined voltage and supplies the predetermined voltage to the main circuit 7. When a predetermined voltage is supplied, the main circuit 7 executes processing for receiving an order. Therefore, detection of supply of the charging voltage to the order receiving terminal device 1 </ b> A serves as a trigger for starting the operation of the main circuit 7.

  For this reason, it is possible to eliminate the need for a power switch that is a mechanical switch that has conventionally created a trigger for starting a process for receiving an order. Further, unlike the prior art, it is not necessary to manage the battery removed from the order receiving terminal device. Therefore, it is possible to prevent the user's inconvenience due to the presence of the mechanical switch power switch and the user's inconvenience due to managing the battery.

  The power supply control circuit 6 transforms the voltage of the battery 3 to a predetermined voltage and supplies the predetermined voltage to the main circuit 7 when at least one of the charge monitoring signal and the power supply lock signal is received.

  In this case, even if the order receiving terminal device 1A is separated from the charger 2A after a predetermined voltage is supplied to the main circuit 7, if the main circuit 7 provides a power lock signal to the power control circuit 6, the main It is possible to prevent the processing of the circuit 7 from stopping. For this reason, the customer can use the order receiving terminal device 1A in which the main circuit 7 is operating in a state separated from the charger 2A.
