[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 is equipped with 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 is equipped with the USB interface 214 into which a USB cable can be inserted and is connectable to the PC terminal 16 via a USB cable 28. This allows the recording device 10 to operate using power supplied from the PC terminal 16 via the USB cable.

[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 may be connected to a mobile battery via a USB cable and can operate with the power supplied from the mobile battery.

[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 use a USB interface, but is not limited to this. The recording device 10 operates with 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, for example, a router equipped with an access point function, may be used.

[0016] <Configuration of the control system of the recording device> Next, the configuration of the control system of the recording device 10 will be described. Fig. 2 is a block diagram showing the configuration of the control system of the recording device 10. The recording device 10 includes a main board 202 that performs overall control of the recording device 10, a reading unit 204 that reads an original, a recording unit 206 that records 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 performing short-range wireless communication, and a USB interface 214 that can be connected to a USB cable.

[0017] 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 section control circuit 224 for controlling the reading section 204, a recording section control circuit 226 for controlling the recording section 206, and an operation section 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 components provided on the main board 202 are connected to each other via an internal bus 238.

[0018] 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. Furthermore, by writing various setting values, data, and the like to the non-volatile memory 222, the CPU 216 can continue to operate based on the setting values ​​and data written to the non-volatile memory 222 when the power is turned ON again after being turned OFF. As the non-volatile memory 222, for example, a semiconductor storage device such as a flash memory can be used.

[0019] 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 stored in the data memory 220. Furthermore, the CPU 216 controls the operation unit control circuit 228 to display the status of the recording device 10 on the display unit 240 provided on the operation panel 208, display a menu of selectable functions, and accept operations from the user.

[0020] The CPU 216 controls the wireless LAN unit 210 via the wireless LAN communication control circuit 230 to perform wireless LAN communication with other communication terminal devices. The CPU 216 also controls the short-distance wireless communication unit 212 via the short-distance wireless communication control circuit 232 to detect a connection with another short-distance wireless communication terminal and to transmit and receive data to and from the other short-distance wireless communication terminal. The CPU 216 also operates the USB interface 214 via the USB communication control circuit 234 to perform USB communication with other terminal devices (external devices) connected by a USB cable. The CPU 216 also controls the 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.

[0021] <Configuration of the power supply system of the recording device> Next, the configuration of the power supply system of the recording device 10 will be described. Fig. 3 is a block diagram showing the configuration of the power supply system of the recording device 10. 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 504 (see Fig. 5) and the recording head 404 (see Fig. 4).

[0022] The recording device 10 is connected to the power supply V BAT The recording device 10 is configured to be driven by inputting the power supply voltage Vcc to the Charger IC 304, and the power supply is controlled by the power supply system via the Charger IC 304. That is, the recording device 10 is configured to operate by the power supplied from the EDLC 302. Specifically, the Charger IC 304 outputs the power supplied from the EDLC 302 to the DC-DC (boosting) 306. The voltage boosted by the DC-DC 306 is used by the 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 the Head Driver 312 to drive the reading head 504 of the reading unit 204 and the recording head 404 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 power boosted by the DC-DC 306 is input to the DC-DC 308, which generates logic power supply voltages used by the ASIC 314, ROM 316, and DDR 318. The ASIC 314 is a custom IC that includes the CPU 216 and peripheral circuits.

[0023] 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.

[0024] Since the Charger IC 304 cannot perform USB enumeration processing (hereinafter simply referred to as "enumeration processing"), the enumeration processing is executed in the ASIC 314 connected to the Charger IC 304. For example, if the PC terminal 16 is connected to the USB interface 214, the ASIC 314 performs enumeration processing with the PC terminal 16, and outputs an instruction to the Charger IC 304 to control a change in the charging current of the EDLC 302 based on the processing result.

[0025] 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. In this way, in this embodiment, the Charger IC 304 functions as a charging unit that charges the EDLC 302.

[0026] The EDLC 302 is a storage battery, and is charged by the Charger IC 304 according to the instructions of the ASIC 314. It also supplies the power V BAT In the recording device 10, the EDLC 302 is charged with power supplied from an external device connected via the USB interface 214. In this embodiment, power is supplied from the PC terminal 16, the smartphone 30, the USB power adapter 34, or a mobile battery (not shown) that is connected to the recording device 10 as an external device. Specifically, the power supply voltage V BAT can be transmitted from the Charger IC 304 to the ASIC 314. For example, during a recording operation of the recording device 10, the power supply voltage V BAT When the power supply voltage V BAT The ASIC 314 then issues an instruction to the Charger IC 304 to control charging until the power supply voltage V BAT The recording operation is resumed when a notification that the current has reached a certain threshold is received from the charger IC 304. In this manner, in this embodiment, the EDLC 302 functions as a power storage unit that stores power.

[0027] <Configuration of the recording unit in the recording device> Next, the configuration of the recording unit 206 in the recording device 10 will be described. FIG. 4 is a schematic diagram of the recording unit 206. The recording unit 206 includes a transport unit 402 that transports the recording medium M in the Y direction, and a recording head 404 that ejects ink onto the recording medium M transported by the transport unit 402 to perform recording. The recording unit 206 also includes a carriage 406 on which the recording head 404 is mounted and which is movable in a direction (X direction) intersecting (orthogonal in this embodiment) the transport direction (Y direction) of the recording medium M transported by the transport unit 402. The recording device 10 also includes a maintenance unit 408 that can execute maintenance processing to favorably maintain and restore the ink ejection performance of the nozzles that eject ink in the recording head 404.

[0028] The print head 404 is configured to be capable of ejecting a plurality of different types of ink. A plurality of nozzles ejecting each ink are arranged in parallel along a direction intersecting the X direction to form a nozzle row. In this embodiment, the print head 404 is configured to be capable of ejecting four types of ink: black (K) ink, cyan (C) ink, magenta (M) ink, and yellow (Y) ink. Note that the types and numbers of inks ejected from the print head 404 are not limited to those described above.

[0029] The carriage 406 is slidably mounted on a guide shaft 410 extending in the X direction, and is connected to a carriage motor 414 via a belt 412. This allows the carriage 406 to move back and forth in the X direction by being driven by the carriage motor 414. Therefore, the recording head 404 mounted on the carriage 406 is configured to be able to move (scan) from one side to the other side and from the other side to one side in the X direction via the carriage 406.

[0030] During a printing operation, a drive pulse is applied to the print head 404 while the carriage 406 is scanned in the X direction, causing the print head 404 to eject ink onto the printing medium M, thereby performing one scan's worth of printing on the printing surface Mp of the printing medium M. The carriage 406 is provided with a detection unit 416 capable of detecting the printing surface Mp of the printing medium M. This allows the printing device 10 to detect the printing surface Mp by the detection unit 416 while moving the carriage 406, and to monitor the printing results by the print head 404 on the printing surface Mp.

[0031] The conveying unit 402 includes a conveying roller 418 that conveys the recording medium M, and a conveying motor 420 that drives the conveying roller 418. In FIG. 4, the conveying roller 418 and the recording medium M are shown separated in the Z direction for ease of understanding, but in reality, the recording medium M and the conveying roller 418 are in contact in the Z direction. In the conveying unit 402, the conveying motor 420 is driven to convey the recording medium M in the Y direction by the conveying roller 418. When performing printing on the recording medium M based on a job, a printing operation is performed in which ink is ejected from the print head 404 to print one scan on the recording medium M conveyed to the printing start position by the conveying unit 402. Thereafter, a conveying operation is performed to convey the recording medium M by a predetermined amount by the conveying unit 402, and then a printing operation is performed again. In this way, in the recording device 10, printing on the recording medium based on a job is performed by alternately and repeatedly executing a printing operation for one scan and a conveying operation for a predetermined amount.

[0032] The maintenance unit 408 is disposed within the movement area of ​​the carriage 406 in the X direction, but outside the area where the recording head 404 records on the recording medium M. The maintenance unit 408 includes a cap unit 422 that comes into contact with (caps) the recording head 404 to protect the nozzle surface 404a of the recording head 404. Although detailed explanation and illustrations are omitted, the maintenance unit 408 includes various known maintenance members, such as a suction unit that creates a negative pressure inside the cap unit 422 and a wiper unit that wipes the nozzle surface 404a. The nozzle surface 404a is the surface of the recording head 404 that faces the recording surface Mp of the recording medium M being transported, and is the surface on which nozzles that eject ink are formed.

[0033] When capping with the cap unit 422, the recording head 404 is moved to a position (a standby position described later) where the nozzle surface 404a faces the cap unit 422 of the maintenance unit 408 (see the dashed line in FIG. 4), and then the cap unit 422 is raised. In this embodiment, the recording head 404 waits at a standby position where the nozzle surface 404a faces the cap unit 422 during timing when the recording operation is not performed. By performing capping after the end of recording based on a job, it is possible to protect the nozzle surface 404a and suppress the evaporation of the liquid component of the ink from the nozzle and the increase in viscosity of the ink in the nozzle due to the evaporation. Note that even if such capping is performed, the ink ejection performance from the nozzle is reduced. For this reason, the maintenance unit 408 executes a maintenance process for maintaining and recovering the ejection performance in a good condition, for example, based on an input from a user via the operation panel 208. In this embodiment, the maintenance unit 408 is configured to include a cap unit 422, but this is not limited to this, and the cap unit 422 may be provided separately from a maintenance unit that includes a suction unit, a wiper unit, etc.

[0034] <Configuration of the reading unit in the recording device> Next, the configuration of the reading unit 204 in the recording device 10 will be described. Fig. 5 is a schematic diagram of the reading unit 204. The reading unit 204 includes a placement unit 502 on which the original S can be placed, a reading head 504 capable of reading the original S placed on the placement unit 502, and a cover unit 506 that presses the original S placed on the placement unit 502 against the placement unit 502. The placement unit 502 is formed of a transparent material such as glass, and the original S placed on the placement unit 502 can be read by the reading head 504 via the placement unit 502.

[0035] The reading head 504 is provided to extend a length corresponding to the length in the X direction of the original S that can be read by the reading unit 204. The reading head 504 is also provided slidably on a guide rail 508 that extends in the Y direction, and is connected to a scanner motor 512 via a belt 510. This allows the reading head 504 to move back and forth in the Y direction by being driven by the scanner motor 512.

[0036] When reading the document S in the reading unit 204, first, with the document S placed on the placement unit 502, the cover unit 506 presses the document S against the placement unit 502. Next, when an instruction to start a reading operation is given from the operation panel 208, the reading head 504 moves from one side to the other in the Y direction and reads the document S placed on the placement unit 502 through the placement unit 502. The read image data is subjected to analysis processing and image processing, and is stored in a storage area such as the data memory 220. The reading unit 204 may be configured to be capable of automatically reading multiple documents by, for example, an ADF (Automatic Document Feeder).

[0037] <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. 6 is a table showing the amount of power supply for each connection standard.

[0038] BC1.2 is based on the USB-BC (Battery Charge) standard, and defines a method for identifying a charging USB port (CDP) by electrically detecting 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.

[0039] 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 6, the maximum power is shown as the value when 5V is supplied.

[0040] <Ability to execute different operation types according to connection standards> Next, the execution capabilities of various operations that can be executed by the recording device 10 according to the connection standard will be described. Fig. 7 is a table showing the execution capabilities of various operations that can be executed by the recording device 10 according to the connection standard. Hereinafter, the "table showing the execution capabilities of various operations that can be executed by the recording device according to the connection standard" will also be appropriately referred to simply as the "table showing execution capabilities".

[0041] 7, the execution capability of each operation is shown by combining the type of operation (operation type) that can be executed by the recording device 10 with the type of power supply standard (connection standard in FIG. 6). In the recording device 10, a table showing the execution capabilities as shown in FIG. 7 may be stored as table data in the program memory 218, or may be implemented as program code or discrimination code.

[0042] The types of operations include a copy operation for recording a scanned document, a recording operation for recording based on recording data, a reading operation for reading a document, and a maintenance operation for the recording head 404. The maintenance operation includes, for example, forcibly sucking ink from the nozzles that eject ink, ejecting ink that does not contribute to recording into the cap portion 422 for protecting the head in which the nozzles are formed, and wiping the surface in which the nozzles are formed. When performing a maintenance operation, power is consumed for driving the pump for suction, ejecting ink, moving the wiper for wiping, and the like.

[0043] The operation types include a capping operation for protecting the recording head 404 with the cap portion 422. By protecting the surface of the recording head 404 on which the nozzles are formed with the cap portion 422, it is possible to prevent the ink from drying or solidifying in the nozzles, and also to prevent the recording head 404 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 for moving the recording head 404 to the standby position and for pressing the cap portion 422 against the recording head 404, but if it is only the capping operation, the power consumption can be reduced more than in the maintenance operation. In FIG. 7, the power consumption of the operation types generally increases toward the top of the table.

[0044] In FIG. 7, the execution capability for each operation type is expressed in three levels: "o", "△", and "x". "o" indicates that the amount of power required for the operation is less than the power supply capability, i.e., the amount of power supplied via the USB cable, in a combination of the operation type and the type of power supply standard, and therefore the amount of stored power in the EDLC 302 will not run out (or will not fall below a certain level) during operation. Note that the "amount of power supplied via the USB cable" is the "amount of power supplied from the terminal device connected via the USB cable". Therefore, an operation marked "o" can be executed continuously. "△" indicates that the amount of power required for the operation is greater than or equal to the power supply capability, i.e., the amount of power supplied via the USB cable, and therefore the amount of stored power in the EDLC 302 will run out (or will fall below a certain level) during operation. Therefore, the operation can be executed by stopping the operation and charging the EDLC 302. Therefore, an operation marked "△" cannot be executed continuously, but can be executed conditionally, for example, by executing it intermittently with appropriate pauses for charging. An "X" indicates that the power required for operation is significantly greater than the power supply capacity, and even if the EDLC 302 is charged, the operability is significantly reduced and it is not practical.

[0045] <Startup notification process> In the above configuration, when the recording device 10 is started after being connected to an external device (external power source) via a USB cable, a startup notification process is executed to notify the recording time per recording medium according to the amount of power supplied from the USB cable. That is, in the recording device 10, a USB cable is connected to the USB interface 214, and the power supply control circuit 236 receives power from the USB interface, and the recording device 10 enters a startup standby state. Then, when the user operates the operation panel 208 to press a startup button (not shown) from this state, this startup notification process is started. Alternatively, the power supply control circuit 236 may be automatically started when it receives power and charges the EDLC 302, and this startup notification process may be started.

[0046] Fig. 8 is a flowchart showing the detailed processing contents of a startup notification process that notifies the user of the recording time per recording medium according to the amount of power supplied from the USB cable when the recording device 10 is started. The series of processes shown in the flowchart in Fig. 8 are performed by the CPU 216 expanding the program code stored in the program memory 218 into the data memory 220 and executing it. Alternatively, some or all of the functions of the steps in Fig. 8 may be performed by hardware such as an ASIC or an electric circuit. In this specification, the reference numerals in the explanation of each process in the flowchart refer to the steps in that flowchart.

[0047] When the start-up notification process is started, first, in S802, the CPU 216 acquires information on power supply from the USB interface 214 (hereinafter, also referred to as "power supply information"). In this embodiment, the power supply information includes a connection standard and a power supply amount. When the recording device 10 is started, the ASIC 314 performs an enumeration process with an external device connected to the USB interface 214 via a USB cable. Then, based on the result of the enumeration process, an instruction is output to the Charger IC 304 to control a change in the charging current of the EDLC 302. The Charger IC 304 judges whether the standard is USB-BC or USB-PD. Therefore, the amount of power supplied from the USB interface 214 is known by the Charger IC 304 or the ASIC 314. Therefore, in S802, the amount of power supplied from the USB interface 214 acquired by the Charger IC 304 or the ASIC 314 is acquired. Note that the power supply information from the USB interface 214 may be configured to be acquired only from the Charger IC 304. Therefore, in S802, the power supply information acquired in the enumeration process is used. In this manner, in this embodiment, the CPU 216 (which may include the charger IC 304 and the ASIC 314) functions as an acquisition unit that acquires the power supply information from the USB cable.

[0048] Next, in S804, the CPU 216 acquires the recording time per sheet of the recording medium according to the power supply status from the USB interface 214. In S804, the recording time T0 per sheet of the recording medium is acquired based on the recording speed in the recording device 10 and the power supply information acquired in S802. In S804, first, the recording time Tb serving as a reference per sheet of the recording medium is calculated from the recording speed Fb measured by, for example, a recording device recording productivity measurement method defined in ISO / IEC24734. Note that the recording speed Fb in the recording device 10 is measured, for example, at the time of shipping the recording device 10, and this measured value is set in advance as the recording speed Fb. Then, the recording time to be notified is determined according to a symbol indicating the execution capability of the operation type "recording operation" for the power supply information acquired in S802 in a table showing execution capabilities (see FIG. 7).

[0049] Specifically, when the symbol representing the execution capability is "◯", it is possible to continue the recording operation by power supply via the USB cable, and therefore the recording operation can be completed in the recording time Tb. Therefore, in this case, the notified recording time T0, that is, the recording time per recording medium, is the calculated recording time Tb (recording time T0=recording time Tb). Also, when the symbol representing the execution capability is "×", it is not possible to even perform a conditional recording operation. Therefore, in this case, the notified recording time T0 is not calculated.

[0050] When the symbol representing the execution capability is "△", the recording operation is performed conditionally by power supply from the EDLC 302. That is, a stop period due to charging is inserted, and the recording operation is performed intermittently. For this reason, the notified recording time T0 is added, for example, to the recording time Tb so as to correspond to the stop period due to charging (that is, the charging time) (recording time T0 = recording time Tb + operation extension time TE). The operation extension time TE is, for example, the charging time until a certain amount of charging is completed in the EDLC 302. The certain amount is, for example, the amount of power required for the recording operation to record on a predetermined number of recording media. The charging time is stored, for example, in a storage area such as the data memory 220 according to the power supply information. In this way, in this embodiment, the CPU 216 functions as an acquisition unit that acquires the recording time T0 by adding the operation extension time TE corresponding to the charging time to the recording time Tb according to the power supply information.

[0051] Thereafter, in S806, CPU 216 displays notification screen 902 based on the acquired recording time T0 on display unit 240 of operation panel 208 (see FIG. 9), and ends this startup notification process. Now, with reference to FIG. 9, notification screen 902 notified in the startup notification process will be described. FIG. 9 is a diagram showing an example of a notification screen notified in the startup notification process. FIG. 9(a) shows a notification screen when the symbol representing execution ability is "◯", FIG. 9(b) shows a notification screen when the symbol representing execution ability is "△", and FIG. 9(c) shows a notification screen when the symbol representing execution ability is "X".

[0052] In S806, a notification screen 902 is displayed on the display unit 240. On the notification screen 902, a display message 904 is displayed that displays the recording time per recording medium, a comment that indicates the recording time relatively, and a countermeasure for executing a recording operation, and a connection status 906 that notifies the power supply status. In this manner, in this embodiment, the CPU 216 functions as a notification unit that notifies the recording time by displaying a notification screen that notifies the recording time on the display unit 240.

[0053] In S804, when the recording time T0 is set to the recording time Tb, a display message 904 displays that the recording time per recording medium is Tb, and that recording is possible in normal time as a relative recording time (see FIG. 9(a)). Note that the display message 904 is only required to display at least the recording time per recording medium, and may appropriately add a comment regarding the recording operation that changes according to the power supply information acquired in S802. Also, in the connection status 906, for example, the connection standard: Power Delivery 3.0 and the power supply amount (supplied power): 15 W are displayed based on the power supply information acquired in S802.

[0054] In S804, when the recording time T0 is set to the recording time Tb+operation extension time TE, the display message 904 displays that the recording time per recording medium is the recording time Tb+operation extension time TE. The display message 904 also displays that the recording time will be slower than normal as a relative recording time (see FIG. 9(b)). Furthermore, in the connection status 906, for example, connection standard: charging USB port (CDP) power supply amount (supplied power): 7.5 W is displayed based on the power supply information acquired in S802.

[0055] If the recording time T0 is not calculated in S804, a display message 904 displays a message indicating that the power supply amount is low and recording operation is not possible, and a comment encouraging connection to an external device with a larger power supply amount as a countermeasure (see FIG. 9(c)). Furthermore, a connection status 906 displays, for example, connection standard: USB3.1, power supply amount (power supply) 4.5 W based on the power supply information acquired in S802. In this case, for example, an icon (an exclamation mark in this embodiment) is displayed near the display message 904 to attract the user's attention.

[0056] <Action and effect> As described above, the recording device 10 according to the present embodiment acquires power supply information from an external device connected by a USB cable at startup, and acquires the recording time T0 per recording medium during recording operation based on the acquired power supply information. Specifically, when the combination of the connection standard, power supply time, and recording operation allows continuous recording operation, the recording time when recording at a set recording speed is acquired as the recording time T0. When the combination of the connection standard, power supply time, and recording operation allows intermittent recording operation, the recording time when recording at a set recording speed is added to the time corresponding to the charging time for the EDLC 302 and acquired as the recording time T0. As a result, the recording device 10 according to the present embodiment can acquire the recording time per recording medium as a value according to the power supply situation.

[0057] Second embodiment Next, a recording device according to a second embodiment will be described with reference to Figures 10 and 11. 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.

[0058] The second embodiment differs from the first embodiment in that the remaining recording time required for the recording operation being performed is obtained and notified according to the power supply status.

[0059] <Recording mode> The recording device 10 according to this embodiment is capable of recording in a plurality of recording modes. The recording modes include, for example, a high-speed mode in which the recording speed is fast but the recording quality is low, a standard mode in which the recording speed and recording quality are standard, and a high-quality mode in which the recording quality is high but the recording speed is slow. These recording modes have decreasing power consumption in the order of high-speed mode, standard mode, and high-quality mode. That is, the power consumption is large in the high-speed mode with a fast recording speed, and is small in the high-quality mode with a slow recording speed.

[0060] <Notification process> In the recording device 10 according to this embodiment, when a job is input and the start of recording is instructed, a notification process is executed in parallel with the execution of the recording operation based on the job, which notifies the remaining recording time required for the recording operation being executed, i.e., the time until the recording operation is completed. FIG. 10 is a flowchart showing the detailed processing contents of the notification process for notifying the remaining recording time. A series of processes shown in the flowchart in FIG. 10 is executed by the CPU 216 expanding the program code stored in the program memory 218 into the data memory 220 and executing it. Alternatively, some or all of the functions of the steps in FIG. 10 may be executed by hardware such as an ASIC or an electric circuit.

[0061] 10 is started, first, in S1002, the CPU 216 acquires power supply information from the USB interface 214. The specific process content of S1002 is the same as that of S802 described above, and therefore a description thereof will be omitted. For example, in a startup notification process or the like, if power supply information has already been acquired from the USB interface 214, the already acquired power supply information is acquired in S1002. Then, in S1004, the CPU 216 acquires the print mode set in the job. In this embodiment, any one of the high-speed mode, standard mode, and high-quality mode is set in the job as the print mode during printing.

[0062] Next, in S1006, the CPU 216 acquires the remaining number of scans Sr (the number of scans of the print head 404) on the recording medium being recorded. In S1006, first, the number of scans Sa required for recording on one recording medium is acquired based on the job settings (such as the size of the recording medium). Next, the number of scans Sd already performed on the recording medium being recorded is acquired from the data memory 220. The number of scans Sd already performed on the recording medium being recorded is stored in the data memory 220. The number of scans Sd already performed on the recording medium being recorded is monitored by, for example, the recording unit control circuit 226, and the value is stored in a storage area such as the data memory 220. Then, the number of scans Sr remaining on the recording medium being recorded is calculated by subtracting the number of scans Sd already performed on the recording medium being recorded from the number of scans Sa required for recording on one recording medium.

[0063] Thereafter, in S1008, the CPU 216 acquires the total number of scans Ss for recording media that have not yet been recorded on, based on the settings in the job. In S1008, the total number of scans Ss is acquired by multiplying the number of recording media that have not yet been recorded on by the number of scans Sa required for recording on one recording medium. The number of recording media that have not yet been recorded on is obtained by subtracting the number of recording media that have already been recorded on from the number of recording media corrected in the job. The number of recording media that have already been recorded on is held in a storage area such as the data memory 220, for example, based on monitoring by the recording unit control circuit 226.

[0064] After acquiring the total number of scans Ss to the recording medium not yet recorded, the CPU 216 acquires the time Tr required for the remaining scans in S1010. In S1010, the CPU 216 first acquires the remaining number of scans Sr to the recording medium being recorded acquired in S1006 and the total number of scans Ss to the recording medium not yet recorded acquired in S1008 to acquire the total number of scans St required for the remaining recording. Next, the CPU 216 acquires the time T1 required for one scan based on the recording mode acquired in S1004. In the recording device 10, the time required for one scan set for each of the high-speed mode, standard mode, and high-quality mode is stored in a storage area such as the data memory 220. Then, the CPU 216 multiplies the total number of scans St by the time T1 required for one scan to acquire the time Tr required for the remaining scans.

[0065] Next, in S1012, the CPU 216 acquires the number of charging times Nc required for the remaining recording. In S1012, the number of charging times Nc required for the remaining recording is acquired based on the power consumption E1 required for one scan and the power supply information acquired in S1002. Specifically, in the table showing the execution capabilities in FIG. 7, when the execution capability of the recording operation in the power supply information acquired in S1002 is "◯", the recording operation can be continuously executed without charging, so the number of charging times Nc is "0". Also, in the table showing the execution capabilities in FIG. 7, when the execution capability of the recording operation in the power supply information acquired in S1002 is "△", charging is required, and the recording operation is executed intermittently. Therefore, in this case, in order to acquire the number of charging times Nc, first, the number of scans Sc requiring charging operation is acquired based on the power consumption E1, the power supply amount in the power supply information, information on the EDLC 302 (storage amount and capacity), and the like. In the recording device 10, the power consumption required for one scan set for each of the high-speed mode, standard mode, and high-quality mode is stored in a storage area such as the data memory 220. After that, the total number of scans St required for the remaining recording is divided by the number of scans Sc at which a charging operation is required to obtain the number of charging operations Nc required for the remaining recording.

[0066] Thereafter, in S1014, the CPU 216 acquires the charging time Tc required for the remaining recording. In S1014, first, the charging time required for one charging operation in the EDLC 302 is acquired. The charging time is stored in a storage area such as the data memory 220. Next, the acquired charging time is multiplied by the number of charging times Nc required for the remaining recording to acquire the charging time Tc required for the remaining recording.

[0067] Then, in S1016, the CPU 216 acquires the remaining recording time Tr1 by adding the time Tr required for the remaining scanning acquired in S1010 and the charging time Tc required for the remaining recording acquired in S1014. In this manner, in this embodiment, the CPU 216 functions as an acquisition unit that acquires the remaining recording time Tr1 by adding the charging time Tc required for the remaining recording to the time Tr required for the remaining scanning according to the power supply information. Thereafter, in S1018, the CPU 216 displays a notification screen 1102 (see FIG. 11) based on the remaining recording time Tr1 acquired in S1016 on the display unit 240 of the operation panel 208. Note that in S1018, if the notification screen 1102 is already displayed on the display unit 240, the notification screen 1102 is updated.

[0068] Here, the notification screen 1102 will be described with reference to Fig. 11. Fig. 11 is a diagram showing an example of a notification screen for notifying the remaining recording time Tr1. The notification screen 1102 displays, as a display message 1104, that recording is in progress. The notification screen 1102 also displays, as a connection status 1106, the connection standard and the amount of power supply based on the power supply information acquired in S1002. The notification screen 1102 also displays, as a remaining time display 1108, that the time until recording is completed is the remaining recording time Tr1 acquired in S1018.

[0069] Return to FIG. 10. After displaying the notification screen 1102 on the display unit 240, the process proceeds to S1020, where the CPU 216 determines whether or not a predetermined time has elapsed since updating the notification screen 1102. In S1020, the CPU 216 determines whether or not a predetermined time has elapsed since displaying the notification screen 1102 on the display unit 240 at the first determination. If it is determined in S1020 that the predetermined time has not elapsed, the CPU 216 performs the determination in S1020 again. On the other hand, if it is determined in S1020 that the predetermined time has elapsed, the process proceeds to S1022, where the CPU 216 determines whether or not the job-based recording has ended. If it is determined in S1022 that the job-based recording has not ended, the process returns to S1006. If it is determined in S1022 that the job-based recording has ended, the CPU 216 ends this notification process.

[0070] <Action and effect> As described above, the recording device 10 according to this embodiment is adapted to obtain the time required for the remaining scanning in recording based on a job, depending on the recording mode set in the job, etc. Also, the remaining charging time in recording based on a job is obtained, depending on the recording mode and the power supply status from the external power source, etc. Then, based on these times, the remaining recording time required for the recording operation being performed is obtained, and notified via the notification screen 1102. As a result, the recording device 10 according to this embodiment is able to obtain the remaining recording time required for the recording operation being performed, depending on the power supply status.

[0071] Third embodiment Next, a recording device according to a third embodiment will be described with reference to Figures 12 to 15. 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.

[0072] The third embodiment differs from the first embodiment in that the remaining read time required for the read operation being performed during the copy operation and the remaining recording time required for the record operation being performed during the copy operation are acquired and notified according to the power supply status. That is, the recording device 10 according to the third embodiment notifies the remaining read time during the read operation during the copy operation and notifies the remaining record time during the record operation.

[0073] <Operation mode> In the recording device 10 according to the present embodiment, copy operations can be performed in a plurality of operation modes. The operation modes include, for example, a high-speed mode in which the operation speed is fast but the recording quality is low, a standard mode in which the operation speed and recording quality are standard, and a high-quality mode in which the recording quality is high but the operation speed is slow. These operation modes have decreasing power consumption in the order of the high-speed mode, the standard mode, and the high-quality mode. That is, the power consumption is large in the high-speed mode, and the power consumption is small in the high-quality mode. Note that, although the present embodiment is configured to set the operation mode of the copy operation, the present invention is not limited to this, and the recording mode set in the recording operation may be made to correspond to the operation mode of the copy operation.

[0074] A display screen 1502 is displayed on the display unit 240 for part of the setting information of a job for executing a copy operation, for example, when checking the settings (see FIG. 15(a)). FIG. 15(a) shows the display screen 1502 for displaying part of the setting information of a job for executing a copy operation. In the display screen 1502 of FIG. 15(a), the number of copies to be made from the scanned original is displayed as a copy number display 1504. Also, the set operation mode is displayed as a mode display 1506. Furthermore, the connection standard and the power supply status are displayed as a connection status 1508. The power supply information displayed in the connection status 1508 may be displayed based on the power supply information acquired in the startup notification process, for example, or may be acquired when the display screen 1502 is displayed on the display unit 240.

[0075] <Notification process> In the recording device 10 according to this embodiment, when a job is input and a command to start copying is issued, a notification process is executed in parallel with execution of a copy operation based on the job, to notify the remaining reading time and recording time. Fig. 12 is a flowchart showing the detailed processing contents of the notification process to notify the remaining reading time and remaining recording time. Fig. 13 is a flowchart showing the detailed processing contents of a reading time notification process which is a subroutine of the notification process. Fig. 14 is a flowchart showing the processing contents of a recording time notification process which is a subroutine of the notification process.

[0076] A series of processes shown in the flowcharts of Figures 12 to 14 are performed by the CPU 216 expanding the program code stored in the program memory 218 into the data memory 220 and executing it. Alternatively, some or all of the functions of the steps in Figures 12 to 14 may be performed by hardware such as an ASIC or an electric circuit.

[0077] 12 is started, first, in S1202, the CPU 216 acquires power supply information from the USB interface 214. The specific processing content of S1202 is the same as that of S802 described above, and therefore a description thereof will be omitted. Note that, for example, in a startup notification process or the like, if power supply information has already been acquired from the USB interface 214, the already acquired power supply information is acquired in S1202. Also, in S1204, the CPU 216 acquires the operation mode set in the job. In this embodiment, any one of the high-speed mode, standard mode, and high-quality mode is set in the job as the operation mode during copying.

[0078] Next, in S1206, the CPU 216 executes a read time notification process for notifying the remaining read time required for the read operation during the copy operation (see FIG. 13). When the read time notification process is started, first, in S1302, the CPU 216 acquires the remaining movement amount Ar of the read head 504 for reading the document being read. In S1302, first, the CPU 216 acquires the movement amount Aa in the scanning direction (Y direction in FIG. 5) of the read head 504 required for reading one document being read. For this movement amount Aa, for example, the reader control circuit 224 monitors the size in the X direction of the document read by the read head 504, and determines the movement amount in the Y direction according to the size. In this case, the movement amount in the Y direction corresponding to the size in the X direction is stored in a storage area such as the data memory 220. Next, the CPU 216 acquires the movement amount Ad of the read head 504 that has already moved to read the document. The movement amount Ad of the reading head 504 when reading the document is monitored and held, for example, by the reading unit control circuit 224. After that, the movement amount Ad is subtracted from the movement amount Aa to obtain the remaining movement amount Ar of the reading head 504 for reading the document being read.

[0079] Next, in S1304, the time T2 required to read one document is obtained. In the recording device 10, the time required to read one document according to the operation mode is stored in the non-volatile memory 222. Therefore, in S1304, the time T2 required to read one document is obtained from the non-volatile memory 222 based on the operation mode obtained in S1204.

[0080] Then, in S1306, CPU 216 acquires time Tp required to read the remaining part of the document being read. In S1306, CPU 216 multiplies a value obtained by dividing reading time T2 acquired in S1304 by movement amount Aa (acquired during processing in S1302) by the remaining movement amount Ar acquired in S1302 to acquire time Tp required to read the remaining part of the document being read.

[0081] Then, in S1308, the CPU 216 acquires the number of charging times Nc2 required for the remaining reading. In S1308, first, the power consumption E3 required for the remaining reading is acquired from the power consumption E2 when reading one document and the remaining movement amount Ar acquired in S1302. Note that in the recording device 10, the power consumption when reading one document set for each of the high-speed mode, the standard mode, and the high-quality mode is stored in a storage area such as the data memory 220. Then, the number of charging times Nc2 required for the remaining reading is acquired based on the power consumption E3 required for the remaining reading and the power supply information acquired in S1202.

[0082] Specifically, in the table showing the execution capabilities in Fig. 7, if the execution capability of the copy operation in the power supply information acquired in S1202 is "◯", the copy operation can be performed continuously without charging, and the number of charging times Nc2 is "0". Also, in the table showing the execution capabilities in Fig. 7, if the execution capability of the copy operation in the power supply information acquired in S1202 is "Δ", charging is required and the copy operation is performed intermittently. Therefore, in this case, in order to obtain the number of charging times Nc2, the number of charging times Nc2 is obtained based on the power consumption E3, the power supply information acquired in S1202, information on the EDLC 302 (amount of stored power and capacity), etc.

[0083] Next, in S1310, CPU 216 acquires charging time Tc2 required for the remaining reading. In S1310, first, the time required for one charging operation in EDLC 302 is acquired. The time required for one charging operation is stored in a storage area such as data memory 220. Next, the acquired time required for one charging operation is multiplied by the number of charging times Nc2 required for the remaining reading to acquire charging time Tc2 required for the remaining reading.

[0084] Thereafter, in S1312, CPU 216 acquires remaining reading time Tr2 required for the reading operation during the copy operation. In S1312, remaining time Tp required for reading acquired in S1306 and charging time Tc2 required for the remaining reading acquired in S1310 are added together to acquire remaining reading time Tr2. Then, in S1314, CPU 216 displays notification screen 1512 (see FIG. 15B) based on remaining reading time Tr2 acquired in S1312 on display unit 240 of operation panel 208. Note that in S1314, if notification screen 1512 is already displayed on display unit 240, notification screen 1512 is updated.

[0085] Here, the notification screen 1512 will be described with reference to Fig. 15(b). Fig. 15(b) is a diagram showing the notification screen 1512 notifying the remaining reading time Tr2. The notification screen 1512 displays, as a time display 1514, the time until reading is completed based on the remaining reading time Tr2 acquired in S1312. The notification screen 1512 also displays, as a remaining number of sheets 1516, the number of sheets remaining to be read.

[0086] Return to FIG. 13. After displaying the notification screen 1512 on the display unit 240, the process proceeds to S1316, where the CPU 216 determines whether a predetermined time has elapsed since updating the notification screen 1512. In addition, in the first determination in S1316, it is determined whether a predetermined time has elapsed since displaying the notification screen 1512 on the display unit 240. If it is determined in S1316 that the predetermined time has not elapsed, the determination in S1316 is performed again. On the other hand, if it is determined in S1316 that the predetermined time has elapsed, the process proceeds to S1318, where the CPU 216 determines whether reading of the document in the copy operation has been completed. If it is determined in S1318 that reading of the document has not been completed, the process returns to S1302. Also, if it is determined in S1318 that reading of the document has been completed, the read time notification process is terminated, and the process proceeds to S1208, which will be described later.

[0087] Returning to FIG. 12, when the reading time notification process of S1206 ends, next, in S1208, CPU 216 starts a recording time notification process for notifying the remaining recording time in the copy operation (see FIG. 14). When the recording time notification process starts, first, in S1402, CPU 216 acquires the remaining number of scans Sr for the recording medium being recorded. Next, in S1404, CPU 216 acquires the total number of scans Ss for the recording medium not yet recorded based on the settings in the job. After that, in S1406, CPU 216 acquires the time Tr required for the remaining scans. Note that the specific process contents from S1402 to S1406 are the same as those from S1006 to S1010 described above, and therefore description thereof will be omitted.

[0088] Then, in S1408, the CPU 216 acquires the number of charging times Nc required for the remaining recording. In S1408, the number of charging times Nc required for the remaining recording is acquired based on the power consumption E1 required for one scan and the power supply information acquired in S1202. Specifically, in the table showing the execution capabilities in FIG. 7, when the execution capability of the copy operation in the power supply information acquired in S1202 is "◯", the copy operation can be continuously executed without charging, so the number of charging times Nc is "0". Also, in the table showing the execution capabilities in FIG. 7, when the execution capability of the copy operation in the power supply information acquired in S1202 is "△", charging is required, and the copy operation is executed intermittently. Therefore, in this case, in order to acquire the number of power supply times Nc, first, the number of scans Sc requiring charging is acquired based on the power consumption E1, the amount of power supply in the power supply information, information on the EDLC 302, and the like. In the recording device 10, the power consumption required for one scan set for each of the high-speed mode, standard mode, and high-quality mode is stored in a storage area such as the data memory 220. After that, the total number of scans St required for the remaining recording is divided by the number of scans Sc at which a charging operation is required to obtain the number of charging operations Nc required for the remaining recording.

[0089] Thereafter, at 1410, the CPU 216 acquires the charging time Tc required for the remaining recording. Next, at 1412, the CPU 216 acquires the remaining recording time Tr1 in the copy operation. Then, at S1414, the CPU 216 displays a notification screen 1522 (see FIG. 15(c)) based on the acquired remaining recording time Tr1 on the display unit 240 of the operation panel 208. Note that, if the notification screen 1522 is displayed on the display unit 240, the notification screen 1522 is updated. The specific process contents from S1410 to S1414 are the same as those from S1014 to S1018 described above, and therefore will not be described.

[0090] Here, the notification screen 1522 will be described with reference to Fig. 15(c). Fig. 15(c) is a diagram showing the notification screen 1522 notifying the remaining recording time Tr1.
