DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of a recording device, a control method, and a program will be described with reference to the accompanying drawings. Note that the following embodiment does not limit the present invention, and not all of the combinations of features described in the present embodiment are essential to the solution of the present invention. Furthermore, the positions, shapes, and the like of the components described in the embodiment are merely examples, and are not intended to limit the present invention to only those.

[0010] (First embodiment) First, a recording apparatus according to a first embodiment will be described with reference to FIGS.

[0011] <Recording System> 1 is a schematic diagram showing a recording system including a recording device according to the present embodiment. A recording system 12 including a recording device 10 according to the present embodiment includes the recording device 10 that ejects ink to record, and a PC terminal 16 as an external device connected to the recording device 10 via a local area network 14. The recording system 12 includes a wireless LAN access point 18, and the recording device 10 can be connected to the local area network 14 by wirelessly connecting to the wireless LAN access point 18. The recording system 12 also includes a router 22 for connecting the local area network 14 to the Internet 20, and a cloud server 24 connected to the Internet 20. This allows the recording device 10 and the PC terminal 16 to communicate with the cloud server 24 connected to the Internet 20 via the router 22.

[0012] The recording device 10 includes a USB (Universal Serial Bus) interface 214 (see FIG. 2) and is configured to be connectable to various devices. In this embodiment, the recording device 10 includes the USB interface 214 to which a USB cable can be connected, and is connected to the PC terminal 16 via the USB cable 28. This allows the recording device 10 to operate using power supplied from the PC terminal 16 via the USB cable 28. In this manner, in this embodiment, the USB cable including the USB cable 28 functions as a connecting member that connects the recording device 10 to an external device.

[0013] In addition, in the recording system 12, it is also possible to use a smartphone 30 as an external device. In this case, the smartphone 30 and the recording device 10 are connected via a USB cable 32, and the recording device 10 can operate with the power supplied from the smartphone 30. Furthermore, in the recording system 12, the recording device 10 and a USB power adapter 34 are connected via a USB cable 36, and the recording device 10 can operate with the power supplied from a commercial power source. Although not shown in the figure, the recording device 10 is configured to be operable with the power supplied from a mobile battery or a USB host port installed in an airplane or bus seat via a USB cable.

[0014] A wireless LAN infrastructure mode connection 38 is used between the smartphone 30 and the recording device 10 and the wireless LAN access point 18. The recording device 10 has a mode in which it operates as a wireless LAN access point. When the recording device 10 operates as an access point, the smartphone 30 can directly connect (direct connection 40) to the recording device 10. The smartphone 30 can also connect to a cloud server 24 connected to the Internet 20 via a mobile phone network 42.

[0015] When the recording device 10, the PC terminal 16, and the smartphone 30 are connected by a USB cable, data communication between the recording device 10, the PC terminal 16, and the smartphone 30 can be performed using the USB cable, but is not limited to this. The recording device 10 operates using power supplied from the PC terminal 16 and the smartphone 30 connected by a USB cable, and data communication can also be performed using wireless LAN or short-distance wireless communication. The recording system 12 shown in FIG. 1 is an example of a recording system equipped with the recording device 10 according to this embodiment, and may have a different configuration from that shown in FIG. 1. For example, instead of the wireless LAN access point 18 and the router 22, a single configuration equipped with these functions, such as a router equipped with an access point function, may be used.

[0016] <Configuration of the control system of the recording device> Next, a description will be given of the configuration of the control system of the recording apparatus 10. FIG 2 is a block diagram showing the configuration of the control system of the recording apparatus 10.

[0017] The recording device 10 includes a main board 202 that controls the entire recording device 10, a reading unit 204 that reads an original, a recording unit 206 that can record on a recording medium, and an operation panel 208 that can be operated by a user. The recording device 10 also includes a wireless LAN unit 210 for connecting to a wireless LAN, a short-range wireless communication unit 212 for short-range wireless communication, and a USB interface 214 that can be connected to a USB cable. The recording device 10 also includes a maintenance unit 242 that performs maintenance operations to maintain and restore the recording performance of the recording unit 206. Note that detailed configurations of the reading unit 204, the recording unit 206, and the maintenance unit 242 can be achieved using various known techniques, and therefore detailed descriptions thereof will be omitted.

[0018] The main board 202 includes a CPU 216 in the form of a microprocessor, a program memory 218 in the form of a ROM, a data memory 220 in the form of a RAM, and a non-volatile memory 222 capable of retaining stored information even without the supply of power. The main board 202 also includes a reading unit control circuit 224 for controlling the reading unit 204, a recording unit control circuit 226 for controlling the recording unit 206, and an operation unit control circuit 228 for controlling the operation panel 208. The main board 202 also includes a wireless LAN communication control circuit 230 for controlling the wireless LAN unit 210, and a short-range wireless communication control circuit 232 for controlling the short-range wireless communication unit 212. The main board 202 also includes a USB communication control circuit 234 for controlling the drive of the USB interface 214, and a power supply control circuit 236 for controlling the amount of power supplied from the USB interface 214. The main board 202 also includes a maintenance unit control circuit 244 for controlling the maintenance unit 242. The components mounted on the main board 202 are connected to each other via an internal bus 238 .

[0019] The CPU 216 operates based on the control program stored in the program memory 218 and the information held in the data memory 220, using the data memory 220 as a work area. The CPU 216 can also continue to operate based on the setting values ​​and data written in the nonvolatile memory 222 when the power is turned on again after being turned off by writing various setting values ​​and data to the nonvolatile memory 222. For example, a semiconductor storage device such as a flash memory can be used as the nonvolatile memory 222. Although the flash memory can maintain the stored contents even when the power is turned off, there is often a limit to the number of times each memory element can be rewritten. For this reason, it is necessary to design the recording device 10 by taking into consideration the timing at which data is written to the nonvolatile memory 222 during the product life of the recording device 10. In general, the more times the storage device is guaranteed to be rewritten, the higher the unit price of the equipment.

[0020] The CPU 216 controls the reading unit 204 via the reading unit control circuit 224 to read an original document and store the read data as image data in the data memory 220. The CPU 216 also controls the recording unit 206 via the recording unit control circuit 226 to record the image data stored in the data memory 220 on a recording medium based on the recording data obtained by image processing the image data. Furthermore, the CPU 216 controls the operation unit control circuit 228 to display the status of the recording device 10 on a display unit 240 provided on the operation panel 208, display a menu of selectable functions, and accept operations from the user.

[0021] The CPU 216 performs wireless LAN communication with other communication terminal devices by controlling the wireless LAN unit 210 via the wireless LAN communication control circuit 230. The CPU 216 also controls the short-range wireless communication unit 212 via the short-range wireless communication control circuit 232 to detect a connection with another short-range wireless communication terminal and to transmit and receive data to and from the other short-range wireless communication terminal.

[0022] The CPU 216 operates the USB interface 214 via a USB communication control circuit 234, and performs USB communication with other external devices connected via a USB cable. The CPU 216 also controls a power supply control circuit 236 to grasp and control the amount of power supplied from the USB interface 214 and the amount of power stored in the power supply control circuit 236. Furthermore, the CPU 216 controls a maintenance unit 242 via a maintenance unit control circuit 244, and executes various maintenance operations for the recording unit 206.

[0023] <Configuration of the power supply system of the recording device> Next, a description will be given of the configuration of the power supply system of the recording apparatus 10. FIG 3 is a block diagram showing the configuration of the power supply system of the recording apparatus 10.

[0024] The power supply control circuit 236 includes an electric double layer capacitor (EDLC) 302 capable of storing and supplying electricity, and a Charger IC 304 that controls the input current. The power supply control circuit 236 also includes a DC-DC (boost) 306 that is a boost circuit for boosting the voltage from the Charger IC 304, and a DC-DC (step-down) 308 that is a step-down circuit for stepping down the voltage output from the DC-DC 306. The power supply control circuit 236 also includes a Motor Driver 310 that drives the motors in the reading unit 204 and the recording unit 206, and a Head Driver 312 that drives the reading head (not shown) and the recording head (not shown).

[0025] The recording device 10 detects the output voltage V BUS , the output voltage V from the EDLC302 BAT The power supply control circuit 236 can be driven by a DC-DC 306, and the power supply control is performed by a Charger IC 304. The voltage output from the Charger IC 304 is boosted by a DC-DC (boost) 306, and the voltage boosted by the DC-DC 306 is used by a Motor Driver 310 to drive the motors of the reading unit 204 and the recording unit 206. The voltage boosted by the DC-DC 306 is also used by a Head Driver 312 to drive the reading head of the reading unit 204 and the recording head of the recording unit 206. In the power supply control circuit 236, the voltage boosted by the DC-DC 306 is used to drive a relatively large load. Furthermore, the voltage boosted by the DC-DC 306 is input to a DC-DC 308, which generates a logic power supply voltage used by the ASIC 314, the ROM 316, and the DDR 318. The ASIC 314 is a custom IC including a CPU 216 and peripheral circuits.

[0026] The charger IC 304 is an IC having a function of controlling an input current from the USB interface 214, and controlling charging of the EDLC 302 and protecting it from abnormal operation. The charger IC 304 is capable of communicating with the ASIC 314 connected via a control serial bus 320. The control serial bus 320 constitutes a part of the internal bus 238. In this embodiment, communication between the charger IC 304 and the ASIC 314 is performed by a universal asynchronous receiver transmitter (UART) method.

[0027] The Charger IC 304 judges the input current according to the external device (PC terminal 16, smartphone 30, etc.) that supplies the current. In this embodiment, for example, the judgment is made according to the USB-BC (USB Battery Charge) standard (BC judgment) and the USB-PD (USB Power Delivery) standard (CC judgment). The ASIC 314 receives the results of the BC judgment and the CC judgment from the Charger IC 304, and determines thresholds for the charging current, full charge, over-discharge voltage, etc. of the Charger IC 304, and sets the thresholds in the Charger IC 304.

[0028] The EDLC 302 is an electric double layer capacitor. The EDLC 302 is controlled by the Charger IC 304 under the control of the ASIC 314, and outputs the output voltage V BAT The power is supplied by the EDLC302 output voltage V BAT can be transmitted from the Charger IC 304 to the ASIC 314. In addition, various information related to power supply can be transmitted from the Charger IC 304 to the ASIC 314. This information is used for various controls of the recording device 10.

[0029] For example, during the recording operation of the recording device 10, the output voltage of the EDLC 302 BATWhen the voltage drops, the ASIC314 stops recording and the output voltage V BAT The ChargerIC 304 is instructed to control charging until the output voltage V BAT When the EDLC 302 receives a notification from the Charger IC 304 that the EDLC 302 has reached a certain threshold, the EDLC 302 resumes the recording operation. When the power supply is stopped, for example, because the USB cable is unplugged during operation using power supplied from the USB interface 214, the Charger IC 304 notifies the ASIC 314, and the ASIC 314 immediately starts an operation to deal with the power supply stop. In this way, in this embodiment, the EDLC 302 functions as a power storage unit that stores power.

[0030] <Connection standard> Next, a description will be given of the connection standards between the recording device 10 and an external power source (external device). Fig. 4 is a table showing the amount of power supply for each connection standard.

[0031] BC1.2 is based on the USB-BC (Battery Charge) standard, and defines a method for identifying a charging USB port (CDP) by electrically determining it using the D+ and D- signal lines for data communication of the USB port. In addition, in the case of a standard USB port that is not a charging port, after this detection is complete, communication based on the USB standard is carried out, during which the USB version can be identified.

[0032] In addition, USB Type-C defines the Power Delivery standard, which allows the amount of power supply to be notified by communication via the CC pin. Note that the Power Delivery standard also allows the supply voltage to be controlled from 5V to 48V, but in Figure 4, the maximum power is shown as the value when 5V is supplied.

[0033] <Ability to execute different operation types according to connection standards> Next, the execution capabilities of various operations that can be performed by the recording device 10 according to the connection standard will be described. Fig. 5 is a table showing the execution capabilities of various operations that can be performed by the recording device 10 according to the connection standard. Hereinafter, the "table showing the execution capabilities of various operations that can be performed by the recording device according to the connection standard" will also be appropriately referred to simply as the "table showing execution capabilities".

[0034] 5, the execution capabilities are shown as a combination of the type of operation (operation type) that can be performed by the recording device 10 and the type of power supply standard (connection standard in FIG. 4). In the recording device 10, a table showing the execution capabilities as shown in FIG. 5 may be stored as table data in the program memory 218, or may be implemented as program code or discrimination code.

[0035] The types of operations include a copy operation for recording a read document, a recording operation for recording based on recording data, a reading operation for reading a document, and a maintenance operation for the recording unit 206. The maintenance operation includes, for example, forcibly sucking ink from nozzles that eject ink, ejecting ink that does not contribute to recording into a cap for protecting a head in which nozzles are formed, and wiping a surface in which nozzles are formed. When performing a maintenance operation, power is consumed for driving a pump for suction, ejecting ink, moving a wiper for wiping, and the like. Although detailed explanations and illustrations are omitted, the cap, pump, and wiper are provided in the maintenance unit 242.

[0036] The operation types also include a capping operation that protects the head with a cap. By protecting the surface of the head on which the nozzles are formed by capping, it is possible to prevent ink from drying and solidifying inside the nozzles, and also to prevent the head from moving and being damaged due to vibrations when the recording device 10 is carried. During the capping operation, power is consumed to drive the motor to move the head to a position where it can be capped and to press the cap against the head, but if it is only the capping operation, power consumption can be reduced more than in the maintenance operation.

[0037] Furthermore, the operation types include display of operation panel 208, wireless LAN communication, and USB communication. Display of operation panel 208, wireless LAN communication, and USB communication are performed in parallel with other operations, but consume power even when other operations are not being performed. For example, display of operation panel 208 consumes power to display a screen on display unit 240. Also, wireless LAN communication consumes power to operate wireless LAN unit 210. In FIG. 5, the power consumption of the operation types generally increases toward the top of the table.

[0038] In FIG. 5, the execution capability for each operation type is expressed in three levels: "o", "△", and "×". "o" indicates that the power required for the operation is lower than the power supply capability, based on the combination of the operation type and the type of power supply standard, so the operation can be executed continuously. "△" indicates that the power required for the operation exceeds the power supply capability, but the operation can be executed by consuming the power stored in the EDLC302. Note that the operation cannot be executed continuously, but it can be executed conditionally by reducing the power consumption per hour, such as by slowing down the speed, or by executing it intermittently with appropriate pauses for charging. "×" indicates that the power required for the operation is significantly higher than the power supply capability, and the operation cannot be executed even conditionally, even if the power of the EDLC302 is used.

[0039] <Notification process> In the above configuration, the recording device 10 executes a notification process at various times to notify information about the power supply status and operation according to the amount of power supplied from the USB interface 214. The notification process executed at each time will be described in detail below.

[0040] =Copy action= First, the notification process executed when a copy operation is started will be described. In the recording device 10, when the start of a copy operation is instructed from the operation panel 208, a notification process is executed to determine whether or not the operation can be executed while notifying information about the power supply status and the operation based on the supplied power. Fig. 6 is a flowchart showing the detailed processing contents of the notification process executed when a copy operation is started. Fig. 7 is a diagram showing an example of a notification screen notifying in the notification process of Fig. 6, where (a) shows a first notification screen notifying that a conditional operation is possible, and (b) shows a second notification screen notifying that the operation is impossible.

[0041] The series of processes shown in the flowchart of Fig. 6 are performed by CPU 216 expanding program code stored in program memory 218 into data memory 220 and executing it. Alternatively, some or all of the functions of the steps in Fig. 6 may be performed by hardware such as an ASIC or an electric circuit. In this specification, the symbol S in the explanation of each process in the flowchart means a step in that flowchart.

[0042] 6 is started, first, in S602, CPU 216 acquires information related to power supply from USB interface 214. In S602, when a USB cable is connected to USB interface 214, the CPU 216 refers to the results of BC judgment and CC judgment detected by power supply control circuit 236, and acquires the connection standard (see FIG. 4), current value, and maximum power as information related to the power supply.

[0043] Next, in S604, the CPU 216 judges whether the power supply amount from the USB interface 214 is 15 W or more. That is, in S604, it is judged whether the maximum power is 15 W or more in the information on power supply acquired in S602. Note that in S604, the judgment may be made based on whether the symbol representing the execution capability in a table indicating the execution capability stored in the program memory 218 is "o". In this case, based on the connection standard and the maximum power in the information on power supply acquired in S602, if the symbol representing the execution capability in the operation type "copy operation" in the table indicating the execution capability is "o", the process proceeds to S606 described later. Also, if the symbol is other than "o", the process proceeds to S608 described later. Alternatively, in S604, the judgment may be made based on the USB standard of the USB cable.

[0044] If it is determined in S604 that the amount of power supplied from the USB interface 214 is 15 W or more, the process proceeds to S606, where the CPU 216 decides to execute the copy operation without conditions, and ends this notification process. After that, the recording device 10 executes the copy operation without conditions based on the contents determined in this notification process. In this embodiment, the "conditions" for various operations are operation conditions for suppressing power consumption, and when an operation is executed with conditions, the operation is executed with an operation condition of, for example, "reducing the speed". In other words, an operation with a condition is an operation in which power consumption is suppressed, that is, an operation with a reduced speed. Also, if it is determined in S604 that the amount of power supplied from the USB interface 214 is not 15 W or more, the process proceeds to S608, where the CPU 216 decides whether the amount of power supplied from the USB interface 214 is 7.5 W or more.

[0045] That is, in S608, it is determined whether the maximum power is 7.5 W or more in the information related to power supply acquired in S602. Note that in S608, the determination may be made based on whether the symbol representing the execution capability in a table indicating the execution capability stored in the program memory 218 is "△". In this case, based on the connection standard and maximum power in the information related to power supply acquired in S602, if the symbol representing the execution capability for the operation type "copy operation" in the table indicating the execution capability is "△", the process proceeds to S610 described later. Also, if the symbol is "×", the process proceeds to S620 described later. Alternatively, in S608, the determination may be made based on the USB standard of the USB cable.

[0046] If it is determined in S608 that the amount of power supplied from the USB interface 214 is 7.5 W or more, the process proceeds to S610, where the CPU 216 displays on the display unit 240 a first notification screen 702 notifying that a conditional operation is possible (see FIG. 7(a)). The first notification screen 702 displays an error message 704 notifying that the amount of power supplied from the USB interface 214 is insufficient. The first notification screen 702 also displays an operation message 706 notifying that the amount of power supplied from the USB interface 214 is insufficient, and therefore the copy operation can be performed by slowing down the speed.

[0047] Furthermore, the first notification screen 702 displays, as a prompt message 708, a prompt for enabling the copy operation to be executed without conditions, for example, a prompt to connect to an external power source that supplies more power from the USB interface 214. Note that the prompt message 708 may be configured to specify a recommended external power source using a two-dimensional code such as a QR code (registered trademark) or a manual, or may be configured to prompt a connection via USB-BC or USB-PD that supplies more power. Furthermore, the first notification screen 702 displays a continue button 710 and a cancel button 712.

[0048] When the continue button 710 is selected, it is determined that the copy operation is performed with conditions. That is, it is determined that the copy operation is performed with the reading speed and the recording speed slowed down. When the cancel button 712 is selected, it is determined that the copy operation is canceled. In this way, in the first notification screen 702, the power supply status is notified that the power supply amount is insufficient, and the information on the operation is notified that the copy operation is performed with conditions and an instruction to enable the copy operation to be performed without conditions. In this way, in this embodiment, the CPU 216 functions as a notification unit that notifies the power supply status and the information on the operation. The notification unit may include an operation unit control circuit 228 for controlling the operation of the operation panel 208.

[0049] After the first notification screen 702 is displayed on the display unit 240, the process proceeds to S612, where the CPU 216 determines whether or not the continue button 710 has been selected. If it is determined in S612 that the continue button 710 has been selected, the process proceeds to S614, where it is determined that a copy operation will be performed conditionally, and this notification process ends. Thereafter, the recording device 10 performs the conditional copy operation based on the contents determined in this notification process.

[0050] Furthermore, if it is determined in S612 that the continue button 710 has not been selected, the process proceeds to S616, where the CPU 216 determines whether or not the cancel button 712 has been selected. If it is determined in S616 that the cancel button 712 has not been selected, the process returns to S612. If it is determined in S616 that the cancel button 712 has been selected, the process proceeds to S618, where the CPU 216 decides to cancel the copy operation, and ends this notification process. Thereafter, the recording device 10 cancels the copy operation based on the content determined in this notification process.

[0051] On the other hand, if it is determined in S608 that the amount of power supplied from USB interface 214 is not 7.5 W or more, the process proceeds to S620, where CPU 216 displays on display unit 240 a second notification screen 752 notifying that the operation cannot be executed (see FIG. 7(b)). The second notification screen 752 provides an error message 754 to notify that the amount of power supplied from USB interface 214 is insufficient. The second notification screen 752 also provides an instruction to enable the copy operation as a prompt message 758, for example, to prompt connection to an external power source that will supply more power from USB interface 214.

[0052] Incidentally, the instruction message 758 may be configured to specify a recommended external power source using a two-dimensional code or a manual, or to encourage connection via USB-BC or USB-PD, which have a large amount of power supply. Furthermore, a cancel button 762 is displayed on the second notification screen 752. When the cancel button 762 is selected, it is decided to cancel the copy operation. In this manner, the second notification screen 752 notifies the user that the amount of power supply is insufficient as the power supply status, and notifies the user of an instruction to enable the copy operation as information related to the operation.

[0053] When second notification screen 752 is displayed on display unit 240, the process proceeds to S622, where CPU 216 determines whether or not cancel button 762 has been selected. If it is determined in S622 that cancel button 762 has not been selected, the process proceeds to S622 again. Note that if the determination in S622 is repeated for more than a predetermined time, the copy operation may be forcibly canceled. If it is determined in S622 that cancel button 762 has been selected, the process proceeds to S618.

[0054] =Maintenance Operation= Next, a notification process executed at the start of a maintenance operation will be described. In the recording device 10, when the start of a maintenance operation is instructed from the operation panel 208, a notification process is executed to determine whether or not the operation can be executed while notifying information about the power supply status and the operation based on the supplied power. Note that the timing at which such a notification process is executed is not limited to the timing at which the instruction to start the maintenance operation is given. For example, if it is necessary to execute a maintenance operation when executing a copy operation or a recording operation, the notification process may be executed before executing the maintenance operation.

[0055] Fig. 8 is a flowchart showing the detailed processing contents of the notification processing executed at the start of the maintenance operation. Fig. 9 is a diagram showing an example of a notification screen given in the notification processing of Fig. 8, where (a) shows a first notification screen giving a notification that a conditional operation is possible, and (b) shows a second notification screen giving a notification that the operation is impossible. The series of processing shown in the flowchart of Fig. 8 is performed by CPU 216 expanding program code stored in program memory 218 into data memory 220 and executing the program code. Alternatively, some or all of the functions of the steps in Fig. 8 may be executed by hardware such as an ASIC or an electric circuit.

[0056] When the notification process of FIG. 8 is started, first, in S802, the CPU 216 acquires information on power supply from the USB interface 214. The specific process content of S802 is the same as that of S602 described above, and therefore the description thereof will be omitted. Next, in S804, the CPU 216 judges whether the amount of power supply from the USB interface 214 is 10 W or more. That is, in S804, it is judged whether the maximum power is 10 W or more in the information on power supply acquired in S802. Note that in S804, the judgment may be made based on whether the symbol representing the execution capability in the table indicating the execution capability stored in the program memory 218 is "o". In this case, if the symbol representing the execution capability in the operation type "maintenance operation" in the table indicating the execution capability is "o" based on the connection standard and the maximum power in the information on power supply acquired in S802, the process proceeds to S806 described later. Also, if the symbol is other than "o", the process proceeds to S808 described later. Alternatively, in S804, the judgment may be made based on the USB standard of the USB cable.

[0057] If it is determined in S804 that the amount of power supplied from the USB interface 214 is 10 W or more, the process proceeds to S806, where the CPU 216 decides to execute the maintenance operation without conditions, and ends this notification process. Thereafter, the recording device 10 executes the maintenance operation without conditions based on the contents determined in this notification process. Also, if it is determined in S804 that the amount of power supplied from the USB interface 214 is not 10 W or more, the process proceeds to S808, where the CPU 216 decides whether the amount of power supplied from the USB interface 214 is 7.5 W or more.

[0058] That is, in S808, it is determined whether the maximum power is 7.5 W or more in the information related to power supply acquired in S802. Note that in S808, the determination may be made based on whether the symbol representing the execution capability in a table indicating the execution capability stored in the program memory 218 is "△". In this case, based on the connection standard and maximum power in the information related to power supply acquired in S802, if the symbol representing the execution capability in the operation type "maintenance operation" in the table indicating the execution capability is "△", the process proceeds to S810 described later. Also, if the symbol is "×", the process proceeds to S820 described later. Alternatively, in S808, the determination may be made based on the USB standard of the USB cable.

[0059] If it is determined in S808 that the amount of power supplied from the USB interface 214 is 7.5 W or more, the process proceeds to S810, where the CPU 216 displays on the display unit 240 a first notification screen 902 notifying that conditional operation is possible (see FIG. 9(a)). The first notification screen 902 displays an error message 904 notifying that the amount of power supplied from the USB interface 214 is insufficient. The first notification screen 902 also displays an operation message 906 notifying that the amount of power supplied from the USB interface 214 is insufficient and therefore that maintenance operation can be performed by slowing down the speed.

[0060] Furthermore, the first notification screen 902 displays, as a prompt message 908, a prompt for enabling the maintenance operation to be performed without conditions, for example, a prompt to connect to an external power source that supplies more power from the USB interface 214. Note that the prompt message 908 may be configured to specify a recommended external power source using a two-dimensional code or a manual, or may be configured to prompt connection via USB-BC and USB-PD that supply more power. Furthermore, the first notification screen 902 displays a continue button 910 and a cancel button 912.

[0061] When the continue button 910 is selected, it is decided to perform the maintenance operation conditionally. In other words, it is decided to perform the maintenance operation at a slower speed. Moreover, when the cancel button 912 is selected, it is decided to cancel the maintenance operation. In this manner, the first notification screen 902 notifies the user that the power supply amount is insufficient as the power supply status. Moreover, the first notification screen 902 notifies the user that the maintenance operation will be performed conditionally and an instruction to enable the maintenance operation to be performed without conditions as information related to the operation.

[0062] When the first notification screen 902 is displayed on the display unit 240, the process proceeds to S812, where the CPU 216 determines whether or not the continue button 910 has been selected. If it is determined in S812 that the continue button 910 has been selected, the process proceeds to S814, where the CPU 216 determines to perform a maintenance operation conditionally and ends this notification process. Thereafter, the recording device 10 performs a maintenance operation conditionally based on the contents determined in this notification process.

[0063] Furthermore, if it is determined in S812 that the continue button 910 has not been selected, the process proceeds to S816, where the CPU 216 determines whether or not the cancel button 912 has been selected. If it is determined in S816 that the cancel button 912 has not been selected, the process returns to S812. If it is determined in S816 that the cancel button 912 has been selected, the process proceeds to S818, where the CPU 216 decides to cancel the maintenance operation, and ends this notification process. Thereafter, the recording device 10 cancels the maintenance operation based on the content determined in this notification process.

[0064] On the other hand, if it is determined in S808 that the amount of power supplied from the USB interface 214 is not 7.5 W or more, the process proceeds to S820, where the CPU 216 displays on the display unit 240 a second notification screen 952 notifying that the operation cannot be executed (see FIG. 9(b)). The second notification screen 952 provides an error message 954 to notify that the amount of power supplied from the USB interface 214 is insufficient. The second notification screen 952 also provides an instruction to enable the maintenance operation to be executed as a prompt message 958, for example, to provide a notification encouraging connection to an external power source that will supply more power from the USB interface 214.

[0065] Incidentally, the instruction message 958 may be configured to specify a recommended external power source using a two-dimensional code or a manual, or may be configured to encourage connection via USB-BC or USB-PD, which have a large amount of power supply. Furthermore, a cancel button 962 is displayed on the second notification screen 952. When the cancel button 962 is selected, it is decided to cancel the copy operation. In this manner, the second notification screen 952 notifies the user that the amount of power supply is insufficient as the power supply status, and notifies the user of an instruction to enable the maintenance operation as information related to the operation.

[0066] When the second notification screen 952 is displayed on the display unit 240, the process proceeds to S822, where the CPU 216 determines whether or not the cancel button 962 has been selected. If it is determined in S822 that the cancel button 962 has not been selected, the process proceeds to S822 again. Note that if the determination in S822 is repeated for more than a predetermined time, the maintenance operation may be forcibly canceled. If it is determined in S822 that the cancel button 962 has been selected, the process proceeds to S818.

[0067] =Recording and reading operations= Next, the notification process executed when starting a recording operation and a reading operation will be described. When the start of a recording operation or a reading operation is instructed from the operation panel 208, the recording device 10 executes a notification process that notifies information about the power supply status and the operation based on the supplied power and determines whether or not to execute the operation.

[0068] FIG. 10 is a flowchart showing the detailed processing contents of the notification processing executed at the start of the recording operation and the start of the reading operation. FIG. 11 shows an example of a notification screen notifying in the notification processing at the start of the recording operation. FIG. 11(a) shows a third notification screen notifying that a conditional operation is possible, FIG. 11(b) shows a first notification screen notifying that a conditional operation is possible, and FIG. 11(c) shows a second notification screen notifying that the operation is impossible. FIG. 12 shows an example of a notification screen notifying in the notification processing at the start of the reading operation. FIG. 12(a) shows a third notification screen notifying that a conditional operation is possible, FIG. 12(b) shows a first notification screen notifying that a conditional operation is possible, and FIG. 12(c) shows a second notification screen notifying that the operation is impossible.

[0069] The series of processes shown in the flowchart of Fig. 10 is performed by CPU 216 expanding program code stored in program memory 218 into data memory 220 and executing it. Alternatively, some or all of the functions of the steps in Fig. 10 may be performed by hardware such as an ASIC or an electric circuit.

[0070] 10 is started, first, in S1002, CPU 216 acquires information regarding power supply from USB interface 214. The specific processing content of S1002 is the same as S602 described above, and therefore the description thereof will be omitted. Next, in S1004, CPU 216 determines whether the amount of power supply from USB interface 214 is 15 W or more. The specific processing content of S1004 is the same as S604 described above. Note that, if a table indicating execution capabilities is used in the processing of S1004, the operation type "recording operation" is referenced at the start of a recording operation, and the operation type "reading operation" is referenced at the start of a reading operation.

[0071] If it is determined in S1004 that the amount of power supplied from USB interface 214 is 15 W or more, the process proceeds to S1006, where CPU 216 decides to execute the operation without conditions and ends this notification process. Thereafter, in recording device 10, if this notification process is started at the start of a recording process, the recording operation is executed without conditions based on the contents determined in this notification process. Also, in recording device 10, if this notification process is started at the start of a reading process, the reading operation is executed without conditions based on the contents determined in this notification process.

[0072] If it is determined in S1004 that the amount of power supplied from the USB interface 214 is not 15 W or more, the process proceeds to S1008, where the CPU 216 determines whether the amount of power supplied from the USB interface 214 is 10 W or more. The specific processing content of S1008 is the same as that of S804 described above. Note that, when a table indicating execution capabilities is used in the processing of 1008, the operation type "recording operation" is referenced at the start of a recording operation, and the operation type "reading operation" is referenced at the start of a reading operation.

[0073] If it is determined in S1008 that the power supply amount from the USB interface 214 is 10 W or more, the process proceeds to S1010, where the CPU 216 determines whether or not the wireless LAN is not connected. In S1010, the short-range wireless communication unit 212 is controlled to detect a connection with another short-range wireless communication terminal. In this manner, in this embodiment, for example, the short-range wireless communication unit 212 functions as a connection unit for wirelessly connecting the recording device 10 to an external device. In addition, in S1010, in addition to the wireless LAN communication, the power consumption of operations executed in parallel with the recording operation and the reading operation, such as display on the display unit 240 and USB communication, may be predicted, and it may be determined whether or not the total power consumption is equal to or greater than a set value. In this case, if it is equal to or greater than the set value, the process proceeds to S1012, which will be described later, and if it is less than the set value, the process proceeds to S1006. The set value is a value set in advance, and is determined, for example, experimentally.

[0074] If it is determined in S1010 that the wireless LAN is not connected, that is, that the device is not connected to another short-range wireless terminal, the process proceeds to S1006. If it is determined in S1010 that the wireless LAN is not not connected, that is, that the device is connected to another short-range wireless terminal, the process proceeds to S1012. In S1012, the CPU 216 displays a third notification screen on the display unit 240 to notify that a conditional operation is possible.

[0075] In the case where this notification process is started at the start of the recording operation, in S1012, a third notification screen 1122 is displayed on the display unit 240 (see FIG. 11(a)). The third notification screen 1122 displays an error message 1124 to notify the user that the amount of power supplied from the USB interface 214 is insufficient. The third notification screen 1122 also displays an operation message 1126 to notify the user that the amount of power supplied from the USB interface 214 is insufficient and that the recording operation can be performed by lowering the speed. The third notification screen 1122 also displays an instruction message 1128 to indicate that the recording operation can be performed without conditions. The instruction may be, for example, a notification to prompt the user to connect to an external power source that supplies more power from the USB interface 214 or to perform the recording operation via USB communication. Furthermore, the third notification screen 1122 displays a continue button 1130 and a cancel button 1132. When the continue button 1130 is selected, it is determined that the recording operation is performed with conditions. That is, it is determined that the recording operation will be performed at a slower speed. Also, when the cancel button 1132 is selected, it is determined that the recording operation will be canceled. In this manner, the third notification screen 1122 notifies the user that the power supply amount is insufficient as the power supply status, and notifies the user that the recording operation will be performed with conditions and an instruction to enable the recording operation to be performed without conditions as information related to the operation.

[0076] Moreover, in the case where this notification process is started at the start of the reading operation, in S1012, a third notification screen 1222 is displayed on the display unit 240 (see FIG. 12(a)). In the third notification screen 1222, a notification is given as an error message 1224 to indicate that the amount of power supplied from the USB interface 214 is insufficient. In addition, in the third notification screen 1222, a notification is given as an operation message 1226 to indicate that the amount of power supplied from the USB interface 214 is insufficient and therefore the reading operation can be performed by lowering the speed. Furthermore, in the third notification screen 1222, an instruction is given as an instruction message 1228 to indicate that the reading operation can be performed without conditions. As the instruction, for example, a notification is given to prompt connection to an external power source that supplies more power from the USB interface 214 or to perform the reading operation via USB communication. Furthermore, in the third notification screen 1222, a continue button 1230 and a cancel button 1232 are displayed. When the continue button 1230 is selected, it is decided to perform the reading operation with conditions. That is, it is determined that the reading operation will be performed at a slower speed. Also, when the cancel button 1232 is selected, it is determined that the reading operation will be canceled. In this manner, the third notification screen 1222 notifies the user that the power supply amount is insufficient as the power supply status, and notifies the user that the reading operation will be performed with conditions and an instruction to enable the reading operation to be performed without conditions as information related to the operation.

[0077] When the third notification screen 1122 (1222) is displayed on the display unit 240, the process proceeds to S1014, where the CPU 216 determines whether or not the continue button 1130 (1230) has been selected. If it is determined in S1014 that the continue button 1130 (1230) has been selected, the process proceeds to S1016, where the CPU 216 determines to perform a recording operation (reading operation) conditionally, and ends this notification process. Thereafter, the recording device 10 performs a recording operation or a reading operation conditionally, based on the contents determined in this notification process.

[0078] Also, if it is determined in S1014 that the continue button 1130 (1230) has not been selected, the process proceeds to S1018, where the CPU 216 determines whether or not the cancel button 1132 (1232) has been selected. If it is determined in S1018 that the cancel button 1132 (1232) has not been selected, the process returns to S1014. If it is determined in S1018 that the cancel button 1132 (1232) has been selected, the process proceeds to S1020, where the CPU 216 decides to cancel the recording operation (reading operation), and ends this notification process. Thereafter, the recording device 10 cancels the recording operation or the reading operation based on the content determined in this notification process. Note that, in the recording device 10, after canceling the recording operation (reading operation), wireless LAN setting may be executed, and the connection may be automatically changed from a wireless connection to a wired connection via a USB cable.

[0079] On the other hand, if it is determined in S1008 that the amount of power supplied from the USB interface 214 is not 10 W or more, the process proceeds to S1022, where the CPU 216 determines whether the amount of power supplied from the USB interface 214 is 7.5 W or more. The specific processing content of S1022 is the same as that of S608 described above. Note that, if a table showing execution capabilities is used in the processing of S1022, the operation type "recording operation" is referenced at the start of a recording operation, and the operation type "reading operation" is referenced at the start of a reading operation. If it is determined in S1022 that the amount of power supplied from the USB interface 214 is 7.5 W or more, the process proceeds to S1024, where the CPU 216 displays a first notification screen on the display unit 240 to notify that a conditional operation is possible.

[0080] If this notification process is started at the start of a recording operation, in S1024, a first notification screen 1102 is displayed on the display unit 240 (see FIG. 11(b)). The first notification screen 1102 notifies, as an error message 1104, that the amount of power supplied from the USB interface 214 is insufficient. The first notification screen 1102 also notifies, as an operation message 1106, that the amount of power supplied from the USB interface 214 is insufficient, and therefore the recording operation can be performed by slowing down the speed. The first notification screen 1102 also displays, as a prompt message 1108, a prompt for enabling the recording operation to be performed without conditions, for example, a prompt for connection to an external power source that supplies more power from the USB interface 214. Note that the prompt message 1108 may be used to specify a recommended external power source using a two-dimensional code or a manual, or may be used to prompt connection via USB-BC and USB-PD that supply more power.

[0081] Furthermore, the first notification screen 1102 displays a continue button 1110 and a cancel button 1112. When the continue button 1110 is selected, it is decided that the recording operation will be executed conditionally. In other words, it is decided that the recording operation will be executed at a slower speed. When the cancel button 1112 is selected, it is decided that the recording operation will be canceled. In this way, the first notification screen 1102 notifies the user that the amount of power supply is insufficient as the power supply status, and notifies the user that the recording operation will be executed conditionally and an instruction to enable the recording operation to be executed without conditions as information related to the operation.

[0082] Moreover, in the case where this notification process is started at the start of the reading operation, in S1024, a first notification screen 1202 is displayed on the display unit 240 (see FIG. 12(b)). The first notification screen 1202 issues a notification as an error message 1204 indicating that the amount of power supplied from the USB interface 214 is insufficient. The first notification screen 1202 also issues a notification as an operation message 1206 indicating that the amount of power supplied from the USB interface 214 is insufficient and therefore the reading operation can be executed by lowering the speed. Furthermore, the first notification screen 1202 displays an instruction as a prompt message 1208 to enable the reading operation to be executed without conditions, for example, a notification to encourage connection to an external power source that supplies more power from the USB interface 214. Note that the prompt message 1208 may be configured to specify a recommended external power source using a two-dimensional code or a manual, or may encourage connection via USB-BC and USB-PD that supply more power.

[0083] Furthermore, the first notification screen 1202 displays a continue button 1210 and a cancel button 1212. When the continue button 1210 is selected, it is decided to execute the reading operation conditionally. In other words, it is decided to execute the reading operation at a slower speed. Furthermore, when the cancel button 1212 is selected, it is decided to cancel the reading operation. In this manner, the first notification screen 1202 notifies the user that the amount of power supply is insufficient as the power supply status, and notifies the user that the reading operation will be executed conditionally and an instruction to enable the reading operation to be executed without conditions as information related to the operation.

[0084] When the first notification screen 1102 (1202) is displayed on the display unit 240, the process proceeds to S1026, where the CPU 216 determines whether or not the continue button 1110 (1210) has been selected. If it is determined in S1026 that the continue button 1110 (1210) has been selected, the process proceeds to S1028, where the CPU 216 determines to perform a recording operation (reading operation) conditionally, and ends this notification process. Thereafter, the recording device 10 performs a recording operation or a reading operation conditionally, based on the contents determined in this notification process.

[0085] Also, if it is determined in S1026 that the continue button 1110 (1210) has not been selected, the process proceeds to S1030, where the CPU 216 determines whether or not the cancel button 1112 (1212) has been selected. If it is determined in S1030 that the cancel button 1112 (1212) has not been selected, the process returns to S1026. If it is determined in S1030 that the cancel button 1112 (1212) has been selected, the process proceeds to S1032, where the CPU 216 decides to cancel the recording operation (reading operation), and ends this notification process. Thereafter, the recording device 10 cancels the recording operation or reading operation based on the content determined in this notification process.

[0086] Also, if it is determined in S1022 that the amount of power supplied from the USB interface 214 is not 7.5 W or more, the process proceeds to S1034, where the CPU 216 displays on the display unit 240 a second notification screen notifying that the operation cannot be executed. If this notification process is started at the start of a recording operation, in S1034, a second notification screen 1152 is displayed on the display unit 240 (see FIG. 11(c)). The second notification screen 1152 notifies, as an error message 1154, that the amount of power supplied from the USB interface 214 is insufficient. Also, the second notification screen 1152 displays, as a prompt message 1158, an instruction for enabling the recording operation to be executed, and for example, a notification is given to encourage connection to an external power source that supplies more power from the USB interface 214. Note that the prompt message 1158 may be a two-dimensional code or a manual that allows the user to specify a recommended external power source, or may encourage connection via USB-BC and USB-PD that supply more power. Furthermore, a cancel button 1162 is displayed on the second notification screen 1152. When the cancel button 1162 is selected, it is decided to cancel the recording operation. In this manner, on the second notification screen 1152, a notification that the amount of power supply is insufficient is displayed as the power supply status, and an instruction to enable the recording operation to be executed is displayed as information related to the operation.

[0087] Moreover, in the case where this notification process is started at the start of the reading operation, in S1034, the second notification screen 1252 is displayed on the display unit 240 (see FIG. 12(c)). In the second notification screen 1252, a notification is given as an error message 1254 to indicate that the amount of power supplied from the USB interface 214 is insufficient. In addition, in the second notification screen 1252, an instruction for enabling the reading operation is displayed as a prompting message 1258, for example, a notification is given to encourage connection to an external power source that supplies more power from the USB interface 214. Note that the prompting message 1258 may be a two-dimensional code or a manual that allows a recommended external power source to be specified, or may encourage connection via USB-BC and USB-PD that supply more power. Furthermore, in the second notification screen 1252, a cancel button 1262 is displayed. When the cancel button 1112 is selected, it is decided to cancel the reading operation. In this way, the second notification screen 1252 notifies the user that the amount of power supply is insufficient as the power supply status, and notifies the user of an instruction to enable execution of a recording operation as information related to the operation.

[0088] When the second notification screen 1152 (1252) is displayed on the display unit 240, the process proceeds to S1036, where it is determined whether or not the cancel button 1162 (1262) has been selected. If it is determined in S1036 that the cancel button 1162 (1262) has not been selected, the determination in S1036 is made again. Note that when the determination in S1036 is repeatedly made for more than a predetermined time, the recording operation (reading operation) may be forcibly canceled. Also, if it is determined in S1036 that the cancel button 1162 (1262) has been selected, the process proceeds to S1032.

[0089] =Startup and Wireless LAN Settings= Next, a description will be given of the notification process executed when the recording device 10 is started and when the wireless LAN is set up. When the recording device 10 is started and when the wireless LAN is set up, a notification process is started to notify information related to the power supply status and operation based on the power supplied.

[0090] The notification process at the time of starting up the recording device 10 is executed when a start button (not shown) provided on the operation panel 208 is selected to start up the recording device 10. Specifically, for example, the notification process may be executed immediately after the start up of the recording device 10, or after the completion of the initialization process of the recording device 10, or after the initialization process. Alternatively, the notification process may be executed when the display unit 240 is started up in response to the start up of the recording device 10. The notification process at the time of setting up the wireless LAN may be executed before an instruction to start the wireless LAN setting is input and the wireless LAN setting based on the instruction is executed, or may be executed when the wireless LAN setting based on the instruction is completed.

[0091] Fig. 13 is a flowchart showing the detailed processing contents of the notification processing executed at the time of start-up and at the time of wireless LAN setting. Fig. 14 is a diagram showing an example of a notification screen notifying in the notification processing at the time of start-up, (a) being a first notification screen notifying that a conditional operation is possible, and (b) being a second notification screen notifying that the operation is impossible. Fig. 15 is a diagram showing an example of a notification screen notifying in the notification processing at the time of wireless LAN setting, (a) being a first notification screen notifying that a conditional operation is possible, and (b) being a second notification screen notifying that the operation is impossible.

[0092] 13 is performed by CPU 216 expanding program code stored in program memory 218 into data memory 220 and executing the program code. Alternatively, some or all of the functions of the steps in FIG. 13 may be performed by hardware such as an ASIC or an electric circuit.

[0093] 13 is started, first, in S1302, CPU 216 acquires information regarding power supply from USB interface 214. The specific processing content of S1302 is the same as S602 described above, and therefore the description thereof will be omitted. Next, in S1304, CPU 216 determines whether the amount of power supply from USB interface 214 is 15 W or more. The specific processing content of S1304 is the same as S604 described above. Note that, when using a table indicating execution capabilities in the processing of S1304, the operation type "operation panel display" is referenced at the time of startup, and the operation type "wireless LAN communication" is referenced at the time of wireless LAN setting.

[0094] If it is determined in S1304 that the amount of power supplied from the USB interface 214 is 15 W or more, this notification process ends without displaying a notification screen on the display unit 240. If it is determined in S1304 that the amount of power supplied from the USB interface 214 is not 15 W or more, the process proceeds to S1306, where the CPU determines whether the amount of power supplied from the USB interface 214 is 7.5 W or more. The specific process content of S1306 is the same as S608 described above. Note that, when a table showing execution capabilities is used in the process of S1306, the operation type "operation panel display" is referenced at startup, and the operation type "wireless LAN communication" is referenced at wireless LAN setting.

[0095] If it is determined in S1306 that the amount of power supplied from the USB interface 214 is 7.5 W or more, the process proceeds to S1308, and the CPU 216 displays on the display unit 240 a first notification screen notifying that a conditional operation is possible.

[0096] When this notification process is started at the time of startup, in S1308, a first notification screen 1402 is displayed on the display unit 240 (see FIG. 14(a)). The first notification screen 1402 displays an error message 1404 to notify that the amount of power supplied from the USB interface 214 is insufficient. The first notification screen 1402 also displays an operation message 1406 to notify that the amount of power supplied from the USB interface 214 is insufficient and therefore the copy operation, the recording operation, and the reading operation can be performed by slowing down the speed. The first notification screen 1402 also displays an instruction message 1408 to indicate that the copy operation, the recording operation, and the reading operation can be performed without conditions. The instruction is, for example, a notification to encourage connection to an external power source that supplies more power from the USB interface 214. The instruction message 1408 may be configured to specify a recommended external power source using a two-dimensional code or a manual, or to encourage connection via USB-BC and USB-PD that supply more power.

[0097] Furthermore, the first notification screen 1402 displays an OK button 1414. When the OK button 1414 is selected, it is determined that the user has confirmed the notification content. In this way, the first notification screen 1402 notifies that the power supply amount is insufficient as the power supply status. Furthermore, the first notification screen 1402 notifies that the copy operation, the record operation, and the read operation can be executed with conditions, and an instruction to enable the copy operation, the record operation, and the read operation without conditions, as information on the operation. Note that the operations notified on the first notification screen 1402 are not limited to the copy operation, the record operation, and the read operation. For example, in the table showing the execution capabilities, all operation types whose symbol in the column corresponding to the connection standard in the information on the power supply acquired in S1302 is "△" may be notified, or some of the operation types may be notified.

[0098] Moreover, if this notification process is started during wireless LAN setting, in S1308, a first notification screen 1502 is displayed on the display unit 240 (see FIG. 15(a)). The first notification screen 1502 notifies the user that the amount of power supplied from the USB interface 214 is insufficient as an error message 1504. The first notification screen 1502 also notifies the user that the recording operation and reading operation by wireless LAN communication can be performed by lowering the speed as an operation message 1506, since the amount of power supplied from the USB interface 214 is insufficient. Furthermore, the first notification screen 1502 displays an instruction as a prompt message 1508 to enable the recording operation and reading operation by wireless LAN communication to be performed without any conditions. The instruction, for example, notifies the user to connect to an external power source that supplies more power from the USB interface 214. The prompt message 1508 may be configured to specify a recommended external power source using a two-dimensional code or a manual, or to prompt the user to connect via USB-BC and USB-PD that supply more power.

[0099] Furthermore, the first notification screen 1502 displays an OK button 1514. When the OK button 1514 is selected, it is determined that the user has confirmed the notification content. In this manner, the first notification screen 1502 notifies the user that the amount of power supply is insufficient as the power supply status. The first notification screen 1502 also notifies the user that the recording operation and the reading operation can be performed with conditions, and an instruction to enable the recording operation and the reading operation to be performed without conditions, as information related to the operation.

[0100] When first notification screen 1402 (1502) is displayed on display unit 240, the process proceeds to S1310, where it is determined whether or not OK button 1414 (1514) has been selected. If it is determined in S1310 that OK button 1414 (1514) has not been selected, the determination in S1310 is made again. Note that when the determination in S1310 is repeatedly made for more than a predetermined time, the display of first notification screen 1402 (1502) on display unit 240 may be terminated. Also, if it is determined in S1310 that OK button 1414 (1514) has been selected, this notification process is terminated.

[0101] Furthermore, if it is determined in S1306 that the amount of power supplied from the USB interface 214 is not 7.5 W or more, the process proceeds to S1312, where the CPU 216 displays on the display unit 240 a second notification screen notifying that the operation cannot be executed.

[0102] When this notification process is started at the time of startup, in S1312, a second notification screen 1452 is displayed on the display unit 240 (see FIG. 14(b)). The second notification screen 1452 displays an error message 1454 to notify that the amount of power supplied from the USB interface 214 is insufficient. The second notification screen 1452 also displays an operation message 1456 to notify that the copy operation, the record operation, and the read operation cannot be executed because the amount of power supplied from the USB interface 214 is insufficient. The second notification screen 1452 also displays an instruction to enable the copy operation, the record operation, and the read operation as a prompt message 1458, and for example, a notice is issued to encourage connection to an external power source that supplies more power from the USB interface 214. The prompt message 1458 may be used to specify a recommended external power source using a two-dimensional code or a manual, or may encourage connection via USB-BC and USB-PD that supply more power.

[0103] Furthermore, the second notification screen 1452 displays an OK button 1464. When the OK button 1464 is selected, it is determined that the user has confirmed the notification content. In this way, the second notification screen 1452 notifies that the amount of power supply is insufficient as the power supply status. Furthermore, the second notification screen 1452 notifies that the copy operation, the record operation, and the read operation cannot be executed as information on the operation, and an instruction to enable the copy operation, the record operation, and the read operation. Note that the operations notified on the second notification screen 1452 are not limited to the copy operation, the record operation, and the read operation. For example, in the table showing the execution capabilities, all operation types whose symbols are "x" in the column corresponding to the connection standard in the information on the power supply acquired in S1302 may be notified, or some of the operation types may be notified.

[0104] Moreover, in the case where this notification process is started during wireless LAN setting, in S1312, a second notification screen 1552 is displayed on the display unit 240 (see FIG. 15(b)). The second notification screen 1552 notifies, as an error message 1554, that the amount of power supplied from the USB interface 214 is insufficient. The second notification screen 1552 also notifies, as an operation message 1556, that the amount of power supplied from the USB interface 214 is insufficient, and therefore recording and reading operations cannot be performed by wireless LAN communication. Furthermore, the second notification screen 1552 displays, as a prompt message 1558, a prompt for enabling recording and reading operations by wireless LAN communication to be performed, for example, a prompt for connection to an external power source that supplies more power from the USB interface 214. Note that the prompt message 1558 may be used to specify a recommended external power source using a two-dimensional code or a manual, or may be used to prompt connection via USB-BC and USB-PD that supply more power.

[0105] Furthermore, the second notification screen 1552 displays an OK button 1564. When the OK button 1564 is selected, it is determined that the user has confirmed the notification content. In this manner, the second notification screen 1552 notifies the user that the amount of power supply is insufficient as the power supply status. The second notification screen 1552 also notifies the user that the recording operation and reading operation cannot be performed via wireless LAN communication, and an instruction to enable the recording operation and reading operation via wireless LAN communication, as information related to the operation.

[0106] When second notification screen 1452 (1552) is displayed on display unit 240, the process proceeds to S1314, where it is determined whether or not OK button 1464 (1564) has been selected. If it is determined in S1314 that OK button 1464 (1564) has not been selected, the determination in S1314 is made again. Note that when the determination in S1314 is repeatedly made for more than a predetermined time, the display of second notification screen 1452 (1552) on display unit 240 may be terminated. Also, if it is determined in S1314 that OK button 1464 (1564) has been selected, this notification process is terminated.

[0107] <Action and effect> As described above, the recording device 10 according to the present embodiment notifies the user of the power supply status and information about the operation, including instructions for executing the operation. The information about the operation further includes information about whether the operation can be executed under certain conditions depending on the power supply status. This allows the user to know in advance not only that the recording device 10 cannot operate depending on the power supplied, but also that countermeasures for the operation and the operation can be executed under certain conditions, improving user convenience.

[0108] Furthermore, the recording device 10 notifies the user of information relating to the power supply status and operation at startup, when setting up the wireless LAN, when starting a copy operation, when starting a maintenance operation, when starting a recording operation, and when starting a reading operation. This allows the recording device 10 to notify the user of information relating to the power supply status and operation at various times, improving user convenience.

[0109] Second embodiment Next, a recording device according to a second embodiment will be described with reference to Figures 16 and 17. In the following description, the same or corresponding configurations as those of the recording device according to the first embodiment described above will be denoted by the same reference numerals as those used in the first embodiment, and detailed description thereof will be omitted.

[0110] The second embodiment differs from the first embodiment in that, in addition to the notification process described above, the recording device 10 executes a no-power-supply notification process for notifying that power is not being supplied via the USB cable.

[0111] <No power supply notification processing> In the recording device 10 according to the present embodiment, a no-power notification process that can notify that there is no power supply via the USB cable is executed periodically after startup. The no-power notification process is not limited to being executed periodically after startup, and may be executed before various operations, for example, before the notification process in the first embodiment. In addition, when the no-power notification process is executed periodically, if the notification process in the first embodiment has already notified that the amount of power supply is insufficient, it may be determined that the user has intentionally removed the USB cable, and the notification may be suppressed. Furthermore, for the no-power notification process and the display of a notification screen on the display unit 240 in the no-power notification process, since it is assumed that there is no power supply via the USB cable, the power stored in the EDLC 302 is used.

[0112] Fig. 16 is a flowchart showing the detailed processing contents of the no-power-supply notification processing capable of notifying that no power supply is being provided via the USB cable. Fig. 17 is a diagram showing an example of a fourth notification screen given in the no-power-supply notification processing. The series of processing shown in the flowchart of Fig. 16 is performed by CPU 216 expanding program code stored in program memory 218 into data memory 220 and executing the program code. Alternatively, some or all of the functions of the steps in Fig. 16 may be performed by hardware such as an ASIC or an electric circuit.

[0113] When the no-power-supply notification process is started, first, in S1602, CPU 216 acquires information related to power supply. The specific process content of S1602 is the same as that of S602 described above, and therefore the description thereof will be omitted. Next, in S1604, CPU 216 determines whether or not power is being supplied from USB interface 214, that is, whether power is being supplied from a USB cable connected to USB interface 214. In S1604, if the connection standard, current value, and maximum power, which are information related to power supply, can be acquired in S1602, it is determined that power is being supplied from USB interface 214, and if they cannot be acquired, it is determined that power is not being supplied from USB interface 214.

[0114] If it is determined in S1604 that power is being supplied from the USB interface 214, this no-power supply notification process ends without displaying a notification screen on the display unit 240. If it is determined in S1604 that power is not being supplied from the USB interface 214, the process proceeds to S1606, where the CPU 216 displays a fourth notification screen 1702 on the display unit 240 (see FIG. 17).

[0115] The fourth notification screen 1702 notifies the user that power is not being supplied as an error message 1704. The fourth notification screen 1702 also notifies the user that power is not being supplied from the USB interface 214 as an operation message 1706, and therefore the recording device 10 cannot be operated. The fourth notification screen 1702 also displays an instruction message 1708 to make the recording device 10 operable, for example, to prompt the user to connect to an external power source. The fourth notification screen 1702 also displays an OK button 1714. When the OK button 1714 is selected, it is determined that the user has confirmed the notification content. In this way, the fourth notification screen 1702 notifies the user that power is not being supplied as the power supply status, and notifies the user that the recording device 10 cannot be operated and an instruction to make the recording device 10 operable as information regarding the operation.

[0116] When fourth notification screen 1702 is displayed on display unit 240, the process proceeds to S1608, where it is determined whether or not OK button 1714 has been selected. If it is determined in S1608 that OK button 1714 has not been selected, the determination in S1608 is made again. If it is determined in S1608 that OK button 1714 has been selected, this no-power-supply notification process ends. At this time, display unit 240 ends display of fourth notification screen 1702.

[0117] <Action and effect> As described above, in the recording device 10 according to the present embodiment, the no-power-supply notification process displays the fourth notification screen 1702 notifying that power is not being supplied via the USB cable. The fourth notification screen 1702 notifies the user that power is not being supplied and information related to the operation including an instruction to make the recording device operable. This allows the user to recognize that the recording device 10 is not being supplied with power via the USB cable, i.e., is not connected to an external power source, improving user convenience.

[0118] Third embodiment Next, a recording device according to a third embodiment will be described with reference to Fig. 18. In the following description, the same reference numerals as those used in the first embodiment are used for the same or corresponding configurations as those in the recording device according to the first embodiment, and detailed description thereof will be omitted.

[0119] The third embodiment differs from the first embodiment in that the recording device 10 is capable of notifying the user of information related to the power supply status and operation at a timing desired by the user, in addition to the notification by the notification process described above.

[0120] In the recording device 10 according to this embodiment, when confirmation of power supply to the recording device 10 is instructed by operation on the operation panel 208, a power supply notification screen is notified on the display unit 240. FIG. 18 shows examples of the power supply notification screen, where (a) is a screen notifying that a predetermined amount or more of power is being supplied, (b) is a screen notifying that an amount of power less than a predetermined amount is being supplied, and (c) is a screen notifying that no power is being supplied. Note that the display content on the power supply notification screen is based on, for example, information about power supply at the time when confirmation of power supply is instructed. The information about power supply is acquired by the same process as in S602 described above.

[0121] When the recording device 10 is in a state where a predetermined amount or more of power is being supplied via the USB cable, a power supply notification screen 1802 is displayed on the display unit 240 (see FIG. 18(a)). The power supply notification screen 1802 displays a power supply status message 1804 to notify the user that power is being supplied from the USB interface 214. In this embodiment, the predetermined amount is, for example, 7.5 W. The power supply notification screen 1802 also displays a power supply sufficient message 1806 to notify the user that a predetermined amount or more of power is being supplied. Furthermore, the power supply notification screen 1802 displays an OK button 1808. When the OK button 1808 is selected, it is determined that the user has confirmed the notification content, and the display of the power supply notification screen 1802 is terminated.

[0122] When the recording device 10 is in a state where less than a predetermined amount of power is being supplied via the USB cable, a power supply notification screen 1812 is displayed on the display unit 240 (see FIG. 18(b)). The power supply notification screen 1812 displays a power supply status message 1804 to notify the user that power is being supplied from the USB interface 214. The power supply notification screen 1812 also displays a power supply shortage icon 1814, which is displayed near the power supply status message 1804 and indicates that the amount of power being supplied is less than a predetermined amount. The power supply notification screen 1812 also displays a power supply shortage message 1816 to notify the user that the power supply from the USB interface 214 is insufficient and therefore copying, recording, and reading operations can be performed at a reduced speed.

[0123] Furthermore, the power supply notification screen 1812 displays an instruction as a prompt message 1818 to enable the copy operation, the recording operation, and the reading operation without any conditions. The instruction, for example, is a notification to encourage connection to an external power source that supplies more power from the USB interface 214. The prompt message 1558 may be a two-dimensional code or a manual that allows a recommended external power source to be specified, or may encourage connection via USB-BC and USB-PD that supply more power. The power supply notification screen 1812 also displays an OK button 1808. When the OK button 1808 is selected, it is determined that the user has confirmed the notification content, and the display of the power supply notification screen 1812 ends.

[0124] In this way, the power supply notification screen 1812 notifies the user that power is being supplied as the power supply status, and displays an icon indicating that the amount of supplied power is insufficient. The power supply notification screen 1812 also notifies the user that the copy operation, recording operation, and reading operation can be performed with conditions, and an instruction to enable the copy operation, recording operation, and reading operation to be performed without conditions, as information related to the operation.

[0125] When the recording device 10 is not receiving power via the USB cable, a power supply notification screen 1832 is displayed on the display unit 240 (see FIG. 18(c)). The power supply notification screen 1832 displays a power supply status message 1804 to notify the user that power is not being supplied from the USB interface 214. The power supply notification screen 1832 also displays a no-power icon 1834, which is displayed near the power supply status message 1804 and indicates that power is not being supplied. The power supply notification screen 1832 also displays a no-power message 1836 to notify the user that the recording device 10 cannot be operated unless the USB cable is connected and power is supplied.

[0126] Furthermore, the power supply notification screen 1832 displays an instruction to enable the recording device 10 as a prompt message 1818, for example, a notification to prompt connection to an external power source. Also, an OK button 1808 is displayed on the power supply notification screen 1832. When the OK button 1808 is selected, it is determined that the user has confirmed the notification content, and the display of the power supply notification screen 1832 is terminated.

[0127] In this way, the power supply notification screen 1832 notifies the user that power is not being supplied as the power supply status, and displays an icon indicating that power is not being supplied. The power supply notification screen 1832 also notifies the user that the recording device 10 cannot be operated, and provides instructions to enable the recording device 10, as information related to operation.

[0128] <Action and effect> As described above, in the recording device 10 according to the present embodiment, when a confirmation instruction for power supply is input, a power supply notification screen is displayed on which power supply to the recording device 10 can be confirmed. The power supply notification screen notifies the user of whether power is being supplied, as well as an icon according to the power supply status and information on an operation including an instruction to enable the operation. This allows the user to check the power supply status of the recording device 10 via the USB cable at any time of their choice, improving user convenience.
