[0003] [Patent Document 1] Patent Publication No. 2014-23014 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional technology, images are read during the return path in the opposite direction to that during the forward path. Therefore, images read during the return path may be mirror-inverted, which may require complex control, such as inverting the image data acquired during the return path. Furthermore, depending on the recording device, images read during the return path may be of lower quality than images read during the forward path. To achieve the same quality for each image read during the return path would require a high-performance reading unit and advanced image processing. From this perspective, there is room for improvement in conventional technology.

[0005] An exemplary object of the present invention is to provide a technique that enables a recording device to read both sides of a medium with relatively simple control and a simple configuration. [Means for solving the problem]

[0009] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention claimed. Although multiple features are described in the embodiments, not all of these multiple features are necessarily essential to the invention, and multiple features may be combined arbitrarily. Furthermore, in the accompanying drawings, the same reference numerals are used to designate the same or similar components, and redundant explanations will be omitted.

[0010] First Embodiment The recording device of this embodiment will be described below. In this embodiment, a recording device that combines a flatbed scanner that reads and records images on a medium and an inkjet printer that ejects ink onto the recording medium for recording will be described as an example. However, the present invention is not limited to this form, and can also be applied to a recording device that is a flatbed scanner alone.

[0011] "Recording" not only includes the formation of meaningful information such as characters and figures, but also includes the formation of images, patterns, designs, etc. on a recording medium, whether meaningful or insignificant, or the processing of the medium, regardless of whether it is manifested in a way that can be perceived visually by humans. In addition, although sheet-like paper is assumed as the "recording medium" in this embodiment, it may also be cloth, plastic film, etc.

[0012] FIG. 1 is a perspective view of a recording apparatus 1 according to one embodiment of the present invention. In each figure, arrows X, Y, and Z indicate directions that intersect with each other, and in this embodiment, are perpendicular to each other. When the recording apparatus 1 is placed on a horizontal surface, the left-right direction is the X direction, the front-back direction is the Y direction, and the up-down direction is the Z direction. The X and Y directions can also be called lateral directions.

[0013] (Recording device) The recording device 1 includes a housing 1a, a feeding unit 2 that feeds recording media into the housing 1a, and a discharge unit 3 that discharges recording media on which images have been recorded inside the housing 1a. The feeding unit 2 includes a feeding tray 21 on which recording media are stacked. The feeding tray 21 can be opened and closed relative to the housing 1a, and FIG. 1 shows the feeding tray 21 in a closed state.

[0014] The recording device 1 also includes an operation display unit 4 that displays information about the recording device 1 to the user and accepts user operations, a scanner unit 5 that reads images on a medium (document), and multiple ink tanks 6 that contain ink. The scanner unit 5 includes a cover 51 that can be opened and closed relative to the housing 1a. FIG. 1 shows the cover 51 in a closed state. The rear surface (not shown) of the recording device 1 also includes a power cord connector (not shown) for connecting a power cord, and a USB cable connector (not shown) for connecting to a computer via a USB cable.

[0015] 2 is a perspective view showing the internal configuration of the housing 1a of the recording device 1. The feeding unit 2 has a feeding roller (not shown) that feeds recording media loaded on a feeding tray 21 one by one. The recording device 1 has a transport unit 7 that transports the recording media. The transport unit 7 has a transport roller 72 that transports the recording media fed by the feeding unit 2, a pinch roller 71 that is driven by the transport roller 72, and a platen that supports the recording media transported by the transport roller 72. The recording medium is sandwiched between the transport roller 72 and the pinch roller 71 and can be transported in the ±Y directions.

[0016] The recording device 1 also includes a recording head 8 that records an image by ejecting liquid onto a recording medium transported by a transport unit 7. The recording head 8 is, in other words, an ejection head that ejects liquid. Ink stored in an ink tank 6 is supplied to the recording head 8 via a tube 80. The recording device 1 includes four ink tanks 61 to 64, each containing black ink, cyan ink, yellow ink, and magenta ink. The recording head 8 is disposed opposite a platen. An image is recorded on the recording medium by ejecting ink from the recording head 8 onto the recording medium transported onto the platen. The discharge unit 3 also includes a discharge roller (not shown) that ejects the recording medium recorded on by the recording head 8 onto a tray (not shown).

[0017] The print head 8 has ejection energy generating elements, such as electrothermal transducers (heaters) or piezoelectric elements, and ejects ink from the ejection orifices. When an electrothermal transducer is used, the heat generated by the element causes ink to bubble, and the resulting bubble-forming energy is used to eject ink from the ejection orifices. The print head 8 may use either a serial scan method or a full-line method for printing. In the serial scan method, the print head 8 is mounted on a carriage 91 and moves back and forth in the X direction. The carriage 91 is supported by a main chassis (not shown) and driven by a carriage motor 92 via a timing belt (not shown), moving along a main scanning direction (X direction) that intersects with the print medium transport direction (Y direction). The ejection of ink while moving the print head 8 in the X direction is called a print scan. The printing apparatus 1 alternately prints an image on the print medium by transporting the print medium and performing print scans of the print head 8. In this embodiment, the serial scan method is assumed. In the case of the full-line method, a long recording head 8 extending in the X direction is used to record an image while continuously transporting the recording medium.

[0018] The recording device 1 also includes a recovery unit (not shown). The recovery unit is a mechanism for maintaining the ink ejection performance of the recording head 8, and is disposed at one end of the movement range of the carriage 91 in a position that allows it to face the ejection port surface (not shown) of the recording head 8. The recovery unit includes a cap that covers the ejection surface of the recording head 8, a pump that sucks ink from the recording head 8 through the cap, and other components. The cap can be displaced by a mechanism (not shown) between a position that covers the ejection surface and a position separated from the ejection surface. Covering the ejection surface with the cap can prevent the ink from drying out in the recording head 8. Furthermore, by operating the pump with the ejection surface capped with the cap, it is possible to remove thickened ink adhering to the recording head 8 and fill the recording head 8 with ink.

[0019] The scan unit 5 will be described with reference to Figures 3(a) and 3(b). Figure 3(a) is a partial cross-sectional view of the scan unit 5, and Figure 3(b) is a plan view of the scan unit 5. As shown in Figures 3(a) and 3(b), the scan unit 5 includes an exterior 50, a cover 51 that covers the mounting portion 52, and the mounting portion 52 that forms a mounting area A0 on which the medium M is placed. The scan unit 5 also includes a support member 53 that supports the mounting portion 52, and a reading unit 54 that reads an image of the medium M placed in the mounting area A0 of the mounting portion 52.

[0020] The cover 51 is fixed to the exterior 50 by a rotatable connecting member 51a such as a hinge (see FIG. 8). The cover 51 is opened and closed by manual operation by the user, for example, when placing the medium M on the mounting portion 52. For example, when the reading unit 54 performs a reading operation on the medium M, the cover 51 is closed. As a result, the medium M placed on the mounting portion 52 is sandwiched between the mounting portion 52 and the cover 51. Furthermore, by covering the mounting portion 52 with the cover 51, the influence of noise due to external light from outside the recording device 1 can be suppressed when the image on the medium M is read by the reading unit 54.

[0021] The placing section 52 is a transparent member having optical transparency, such as glass. The image on the placing surface side of the medium M placed on the placing section 52 is read by the reading section 54 through the placing section 52. The placing section 52 is surrounded by a frame, which is a support member 53.

[0022] The reading unit 54 includes a light-emitting element 540 that emits light toward the mounting unit 52, and a light-receiving element 541 that receives light that is emitted from the light-emitting element 540 and reflected by the medium M via the mounting unit 52. The light-emitting element 540 is disposed along a direction (Y direction) that intersects with the movement direction (X direction) of the reading unit 54. The light-emitting element 540 is, for example, an LED. The light-receiving element 541 is disposed along a direction (Y direction) that intersects with the movement direction (X direction) of the reading unit 54. The light-receiving element 541 is, for example, an optical image sensor. In this embodiment, the light-receiving element 541 is, for example, a CCD sensor, but is not limited to this and may be, for example, a CIS sensor, a photodiode, or the like.

[0023] Referring now to FIG. 15, the movement of the reading unit 54 will be described. FIG. 15 is an exploded perspective view of the scanner unit 5. The reading unit 54 is housed in the housing member 5a below the mounting portion 52 and is movable inside the housing member 5a. The scanner unit 5 includes a moving unit 56 that moves the reading unit 54 in the X direction and in the -X direction opposite to the X direction. The moving unit 56 is provided in the housing member 5a and includes a motor 560, a belt 561, and a guide rail 562 for moving the reading unit 54. The reading unit 54 is moved along the guide rail 562 extending in the X direction of the housing member 5a by the belt 561 to which the driving force of the motor 560 is transmitted.

[0024] Next, the operation of reading the medium M by the reading unit 54 will be described with reference to FIG. 4. FIG. 4 is an explanatory diagram of the operation of reading an image of the medium M by the reading unit 54, and corresponds to a partial cross-sectional view of the scan unit 5. The reading unit 54 includes a transparent member 542 that transmits light irradiated from the light-emitting element 540, and a lens 543 for forming an image on the light-receiving element 541. When reading an image of the medium M placed on the mounting unit 52, the reading unit 54 irradiates light toward the mounting unit 52 using the light-emitting element 540 while being moved in the X direction by the moving unit 56. The light irradiated from the light-emitting element 540 is reflected by the medium M via the transparent member 542 and the mounting unit 52. The reading unit 54 then collects the reflected light using the lens 543 and receives it using the light-receiving element 541. The light-receiving element 541 converts the received reflected light into an electrical signal. The electrical signal converted by the light receiving element 541 is transferred to a custom IC 105 of the recording device 1 (to be described later) and stored in the RAM 103 as image data under the control of the CPU 101.

[0025] 5 is an explanatory diagram of the operation display unit 4 on the recording device 1. The operation display unit 4 includes an operation section 40 and a display section 41. The operation section 40 includes a group of multiple buttons that accept various user instructions related to the recording device 1.

[0026] The power button 400 is a button that accepts a switching instruction to switch the power ON and OFF of the recording device 1. The LAN setting button 401 is a button that accepts a connection instruction to connect the recording device 1 to an external device such as a host computer or a smartphone via wireless LAN.

[0027] The setting change button 402 is a button that accepts a user instruction to start changing the settings of the recording device 1. The value setting button 403 is a button that accepts a user instruction to switch values ​​related to various settings, such as the number of copies and the setting number. For example, when the setting change button 402 is pressed by a user, the recording device 1 starts changing the settings of the recording device 1. Then, for example, when the value setting button 403 is pressed by a user, the recording device 1 changes the settings of the recording device 1 depending on the number of times the value setting button 403 is pressed. For example, the recording device 1 sets whether the operation of reading an image of the medium M by the scan unit 5, described later, will be in a single-sided reading mode or a double-sided reading mode based on the user's operation of these buttons. The single-sided reading mode is a setting in which the scan unit 5 reads only one side of the medium M, and the double-sided reading mode is a setting in which the scan unit 5 reads both sides of the medium M.

[0028] The cancel button 404 is a button that accepts a cancel instruction for canceling each instruction on the operation unit 40. The monochrome button 405 is a button that accepts a user instruction to cause the scan unit 5 to read the medium M in monochrome mode. The color button 406 is a button that accepts a user instruction to cause the scan unit 5 to read the medium M in color mode. As will be described later, when either the monochrome button 405 or the color button 406 is pressed, the recording device 1 starts a double-sided reading operation of the medium M.

[0029] The display unit 41 is an interface that displays various information related to the recording device 1 to the user, and includes a light-emitting element 410, a light-emitting element 411, and a monitor 412. The light-emitting element 410 lights up when the power of the recording device 1 is on. The light-emitting element 411 notifies the user of an error if an error occurs in the recording device 1. The light-emitting element 411 may notify the user of an error in the recording device 1 by lighting up or blinking, for example.

[0030] The monitor 412 is, for example, a liquid crystal display, and includes a group of icons 412a and a segment display section 412b. The group of icons 412a lights up depending on the state of the recording device 1 and the settings of the recording device 1. Specifically, the group of icons 412a lights up depending on the state of the wireless LAN of the recording device 1. The group of icons 412a also lights up when the ink tank 6 runs out of ink. The group of icons 412a also lights up when the settings of the main body of the recording device 1 are changed based on the setting button 402 being pressed.

[0031] The segment display section 412b displays a pattern of numerical values ​​according to various settings such as the number of prints, the reading mode, etc. Furthermore, if an error occurs in the recording device 1, the segment display section 412b displays an error code corresponding to the error.

[0032] 6 is a block diagram showing the system configuration of recording device 1. Recording device 1 includes ROM 102, which stores programs for various processes, CPU 101, which controls each unit according to the programs read from ROM 102, and RAM 103, which includes a storage area used as a working area. CPU 101, ROM 102, and RAM 103 are each connected via bus 104 to custom IC 105, which includes an ASIC and FPGA. Custom IC 105 is connected to each unit of recording device 1 and controls each connected unit according to instructions from CPU 101.

[0033] The custom IC 105 controls the driving of each motor 207 via a motor driving circuit 206. The motors 207 include, for example, a carriage motor 92 that moves the carriage 91, a motor for driving the transport roller 72 and feed roller that feed the recording medium, and a motor for the moving unit 56 that moves the reading unit 54.

[0034] Custom IC 105 is connected to operation and display unit 4, and controls the display of display section 41 and accepts user instructions via operation section 40. Custom IC 105 is connected to reading section 54, and controls the light emitting state of light emitting element 540. Custom IC 105 also stores an electrical signal detected by light receiving element 541 in RAM 103 as image data.

[0035] The custom IC 105 performs control in accordance with the recording data and commands received by the operation unit 40. The custom IC 105 is also connected to an I / F (interface) unit 106 such as a USB or wireless LAN for connecting to an external device such as a host computer or smartphone external to the recording device 1.

[0036] (Reading operation) 7 and 8, a description will be given of an example of a user operation when causing the recording device 1 to read a medium M, and an example of the operation of reading the medium M by the recording device 1. FIG. 7 is a perspective view of the recording device 1. First, the user opens the feed tray 21 toward the rear side of the recording device 1. Then, the user loads recording media onto the feed tray 21.

[0037] Next, reference is made to Figure 8. Figure 8 shows a state in which a user has placed a medium M on the placement section 52. The user opens the cover 51 on the rear side of the recording device 1, places the medium M on the placement section 52, and closes the cover 51.

[0038] Next, the user presses the numeric setting button 403 on the operation unit 40 the required number of times to select the number of copies (see FIG. 5).Then, the user selects whether to have the recording device 1 read the medium M in monochrome mode or color mode by pressing either the monochrome button 405 or the button 406.

[0039] The recording device 1 starts a reading operation based on the user pressing either the monochrome button 405 or the color button 406. The recording device 1 controls the movement unit 56 to move the reading unit 54 in the X direction. Then, while moving the reading unit 54 in the X direction, the recording device 1 starts reading an image from the medium M placed in the placement area A0 of the placement unit 52. The recording device 1 stores the image data read by the reading unit 54 in the RAM 103. The recording device 1 then feeds the recording medium loaded on the feed tray 21 into the housing 1a. The recording device 1 then records the image data stored in the RAM 103 onto the recording medium using the recording head 8. For example, if the user selects multiple copies, the recording device 1 sequentially records the image data stored in the RAM 103 onto the set number of recording media. In this manner, the reading operation by the recording device 1 is completed.

[0040] (Double-sided reading of recording device) The recording device 1 is equipped with a control for reading both sides of a medium M. Double-sided reading by the recording device 1 is used in a variety of cases. For example, in recent years, there has been an increase in the need for double-sided images of a medium M, such as a driver's license or My Number card, in various applications, such as hometown tax payments. For example, a user reads both sides of a medium M using the recording device 1. Then, the user can print the read image using the recording device 1 or convert it into a data format, such as PDF, for use.

[0041] Incidentally, for example, in double-sided scanning of a medium M, there is a technique for controlling the scanning of an image on the front side of the medium M during forward movement and the scanning of an image on the back side of the medium M during backward movement. With such a technique, the image is scanned in opposite directions during the forward and backward movements, so the image on the back side scanned during the backward movement may be left-right inverted. Therefore, when managing each scanned image in memory, the image on the front side and the image on the back side are treated as separate images, and complex control is required to invert the data for the image on the back side.

[0042] Furthermore, some recording devices prioritize reading images during forward movement. In such recording devices, images read during backward movement may be of lower quality than images read during forward movement. For example, to ensure that images read during forward movement and images read during backward movement are of the same quality, a high-performance reading unit and advanced image processing may be required.

[0043] Therefore, there is a demand for a technology that enables the recording device 1 to read both sides of the medium M with relatively simple control and a simple configuration. The double-sided reading operation in this embodiment will be described below with reference to FIG. 9. FIG. 9 is an explanatory diagram of the double-sided reading operation of the medium M, and corresponds to a partial perspective view of the scan unit 5. Note that the following processes described in FIG. 9 as being executed by the recording device 1 are realized, for example, by the CPU 101 loading a control program stored in a memory such as the ROM 102 into the RAM 103 and executing it.

[0044] State ST1 in Figure 9 shows the state before the scan unit 5 starts double-sided reading. Before starting double-sided reading, the reading unit 54 waits in an initial position (home position) below the support member 53. In this state ST1, the reading unit 54 is not moved by the moving unit 56 and is in a stopped state. Here, the user places the medium M to be read in the first placement area A1 of the placement area A0 of the placement unit 52.

[0045] When the recording device 1 receives a setting operation from the user, it sets the scanning unit 5 to a double-sided reading mode for the reading operation of the medium M. The setting operation will be described. For example, the recording device 1 starts changing the settings of the recording device 1 based on the user pressing the setting change button 402. Then, when the user further presses the numerical setting button 403, the recording device 1 sets the scanning unit 5 to a double-sided reading mode for the reading operation of the medium M.

[0046] Then, the recording device 1 notifies the user through the display unit 41 that the scanning operation of the medium M by the scan unit 5 has been set to the double-sided reading mode. Specifically, as shown in FIG. 11(a), the recording device 1 displays a predetermined pattern indicating the double-sided reading mode on the segment display unit 412b.

[0047] After setting the double-sided reading mode, when the recording device 1 receives an instruction from the user to start double-sided reading, it controls each part of the scan unit 5 and starts double-sided reading of the medium M. Specifically, for example, when the user presses either the monochrome button 405 or the color button 406, the recording device 1 starts double-sided reading of the medium M.

[0048] 9 shows a state ST2 when the scan unit 5 starts reading the first side S1 of the medium M. First, the recording device 1 sets the light-emitting element 540 to a full light state. Then, the recording device 1 causes the movement unit 56 to move the reading unit 54 a predetermined distance in the X direction, and causes the reading unit 54 to read the image of the first side S1 of the medium M placed in the first placement area A1.

[0049] 9 shows a state when the scan unit 5 has read the first side S1 of the medium M. When the moving unit 56 has moved the reading unit 54 a predetermined distance in the X direction, the recording device 1 temporarily stops the movement of the reading unit 54 by the moving unit 56 between the first loading area A1 and the second loading area A2. By temporarily stopping the reading unit 54 between the first loading area A1 and the second loading area A2, when reading both sides of the medium M, it is possible to provide a timing for the user to turn over the medium M and place it from the first loading area A1 to the second loading area A2.

[0050] Furthermore, when the recording device 1 temporarily stops the movement of the reading unit 54, it changes the light-emitting state of the light-emitting element 540 to a light-emitting state different from the full-light state. That is, the light-emitting element 540 changes from the light-emitting state when the reading unit 54 is being moved by the moving unit 56 to the light-emitting state when the reading unit 54 is temporarily stopped, during the process of the reading unit 54 being moved from the first placement area A1 to the second placement area A2 by the moving unit 56. In this way, the light-emitting state of the light-emitting element 540 changes during the process of the reading unit 54 being moved from the first placement area A1 to the second placement area A2, allowing the user to recognize that the reading operation of the first side S1 of the medium M placed in the first placement area A1 has been completed.

[0051] Furthermore, the light emitting element 540 flashes while the reading unit 54 is temporarily stopped. The flashing of the light emitting element 540 in the recording device 1 makes it easier for the user to recognize that the reading operation of the first surface S1 of the medium M placed in the first placement area A1 has been completed.

[0052] Furthermore, the light emitting state of the light emitting element 540 while the reading unit 54 is temporarily stopped is in a state of lower light emission intensity than the light emitting state of the light emitting element 540 when the reading unit 54 is being moved in the X direction by the moving unit 56. In this way, by lowering the light emission intensity of the light emitting element 540 while the reading unit 54 is temporarily stopped, it is possible to prevent the user from feeling dazzled when looking at the light emitting element 540 when turning over the medium M placed in the first placement area A1 and placing it in the second placement area A2. Note that the recording device 1 may set the light emitting state of the light emitting element 540 while the reading unit 54 is temporarily stopped to a flashing state with low light emission intensity, or may set the light emitting element 540 to a state with low light emission intensity without flashing.

[0053] Furthermore, when reading both sides of the medium M, the recording device 1 notifies the user of the timing to place the medium M placed in the first placement area A1 in the second placement area A2. Specifically, the recording device 1 displays on the display unit 41 that the medium M should be turned over and placed in the second placement area A2. This display will be described in detail later. In this way, the recording device 1 notifies the user, allowing the user to recognize the timing to turn over the medium M.

[0054] State ST4 in FIG. 9 illustrates a state in which the scan unit 5 starts reading the second side S2 of the medium M. When the recording device 1 receives a user instruction to resume the paused movement of the reading unit 54 in the X direction, the recording device 1 causes the movement unit 56 to resume the movement of the reading unit 54 in the X direction. Specifically, for example, when the user presses either the monochrome button 405 or the color button 406, the recording device 1 causes the movement unit 56 to resume the movement of the reading unit 54 in the X direction. Note that the recording device 1 may resume the movement of the reading unit 54 in the X direction not only when the user presses either the monochrome button 405 or the color button 406, but also, for example, when it detects that the cover 51 has entered the closed state. In this way, by causing the movement unit 56 to resume the movement of the reading unit 54 in the X direction when the recording device 1 receives a user instruction, it is possible to prevent reading of the image on the second side S2 of the medium M from being started at a time different from the user's intention.

[0055] The recording device 1 further moves the reading unit 54 in the X direction from the first loading area A1 using the moving unit 56, and causes the reading unit 54 to read the second side S2 of the medium M loaded in the second loading area A2. Thereafter, the recording device 1 moves the reading unit 54 in the direction opposite to the X direction (-X direction) using the moving unit 56, returns the reading unit 54 to its initial position, and ends the double-sided reading operation.

[0056] When a predetermined time has elapsed since the recording device 1 started pausing the reading unit 54, the moving unit 56 moves the reading unit 54 in the direction opposite to the X direction (-X direction) to return the reading unit 54 to its initial position. In other words, if the user does not issue an instruction to resume the movement of the paused reading unit 54 in the X direction within a predetermined time since the recording device 1 started pausing the reading unit 54, the recording device 1 can end the double-sided reading operation.

[0057] As described above, in this embodiment, when reading both sides of a medium M, the recording device 1 controls the movement unit 56 to move the reading unit 54 in the X direction, and reads the first side S1 of the medium M placed in the first placement area A1 of the placement area A0 of the placement unit 52. The recording device 1 then controls the movement unit 56 to further move the reading unit 54 in the X direction from the first placement area A1, and reads the second side S2 of the medium M placed in the second placement area A2 of the placement unit 52. In other words, when reading both sides of a medium M, the recording device 1 controls the reading unit 54 to read images on both sides of the medium M while the reading unit 54 is moving in the X direction, without moving the reading unit 54 in the direction opposite (returning direction) to the X direction (forward direction). In this way, by controlling the movement unit 56 to move the reading unit 54 in one direction and have the reading unit 54 read the images on both sides of the medium M, the recording device 1 can read the images on both sides of the medium M with relatively simple control and a simple configuration.

[0058] 10 is a flowchart showing an example of a double-sided reading process for a medium M executed by the recording device 1 in this embodiment. In this flowchart, the process executed by the recording device 1 is realized, for example, by the CPU 101 loading a control program stored in a memory such as the ROM 102 into the RAM 103 and executing the program.

[0059] In S101, when the CPU 101 receives a user instruction to start a double-sided reading operation via the operation unit 40, it erases the image data stored in the RAM 103 in order to record the image data. The CPU 101 also erases the measurement time data stored in the RAM 103. In S102, the CPU 101 turns on the light-emitting element 540 of the reading unit 54, bringing the light-emitting state of the light-emitting element 540 into a full light state.

[0060] In S103, CPU 101 controls moving unit 56 to move reading unit 54 in the X direction from the initial position. In S104, CPU 101 causes reading unit 54 to read an image of first side S1 of medium M placed in first placement area A1 of placement unit 52 while moving reading unit 54 in the X direction with moving unit 56. Then, CPU 101 acquires image data of first side S1 read by reading unit 54 and stores the acquired image data in RAM 103.

[0061] In S105, the CPU 101 determines whether the movement unit 56 has moved the reading unit 54 a predetermined distance in the X direction. If the CPU 101 determines that the reading unit 54 has moved, the process proceeds to S106. On the other hand, if the CPU 101 determines that the reading unit 54 has not moved, the process proceeds to S103. That is, the CPU 101 repeats the processes of S103 and S104 until the reading unit 54 has moved a predetermined distance that has been set in advance. The predetermined distance is, for example, less than half the length of the movement path over which the moving unit 56 can move. In this way, by setting the predetermined distance to less than half the length of the movement path over which the moving unit 56 can move, it is possible to prevent the second placement area A2 on which the second side S2 of the medium M is placed from becoming narrower.

[0062] The predetermined distance may be, for example, 90 mm or more. By setting the predetermined distance to 90 mm or more, it is possible to move the reading unit 54 and read both sides of an ID card, passport, or the like. An ID card is a medium M on which a user's personal information is printed on both sides, such as a driver's license, health insurance card, or My Number card. The predetermined distance may be, for example, 95 mm or more. By setting the predetermined distance to 95 mm or more, it is possible to move the reading unit 54 and read both sides of a business card, for example. The predetermined distance may be, for example, 100 mm or more. By setting the predetermined distance to 100 mm or more, it is possible to move the reading unit 54 and read both sides of various media M, even if the media M is wide.

[0063] In S106, the CPU 101 temporarily stops the movement of the reading unit 54 by the moving unit 56. In S107, the CPU 101 starts measuring the stop time, and stores the measured time data in the RAM 103 sequentially.

[0064] In S108, the CPU 101 changes the light emitting state of the light emitting element 540 to a blinking state. Also in S108, the CPU 101 reduces the light emitting intensity of the light emitting element 540.

[0065] Furthermore, in S108, the CPU 101 notifies the user of the timing to place the medium M placed in the first placement area A1 in the second placement area A2. Specifically, the CPU 101 displays on the display unit 41 a message indicating that the medium M should be turned over and placed in the second placement area A2. Reference is now made to FIG. 11(b). FIG. 11(b) shows an example of the notification that the CPU 101 displays on the display unit 41 in S108. The CPU 101 alternately displays predetermined characters and a reversed pattern of the predetermined characters on the segment display portion 412b of the display unit 41.

[0066] In the present embodiment, predetermined characters are displayed inverted, but this is not limiting. For example, if the recording device 1 is equipped with a speaker (not shown), the CPU 101 may use the speaker to audibly notify the user that the medium M should be turned over and placed in the second placement area A2. Furthermore, if the recording device 1 is capable of communicating with an external information processing device such as a smartphone or PC owned by the user, the CPU 101 may send a message to the information processing device that prompts the user to turn over the medium M and place it in the second placement area A2.

[0067] In S109, CPU 101 determines whether a user instruction to resume movement of reading unit 54 has been accepted. If CPU 101 determines that a user instruction has been accepted, the process proceeds to S110. On the other hand, if CPU 101 determines that a user instruction has not been accepted, the process proceeds to S116. Specifically, CPU 101 determines whether the user has pressed either monochrome button 405 or color button 406. In other words, monochrome button 405 and color button 406 can also be considered as acceptance buttons that accept a user instruction to resume movement of reading unit 54.

[0068] In S110, the CPU 101 turns on the light emitting element 540, and sets the light emitting state of the light emitting element 540 to a full light state.

[0069] In S111, CPU 101 controls moving unit 56 to move reading unit 54 in the X direction from the pause position. In S112, CPU 101 causes reading unit 54 to read an image of second side S2 of medium M placed in second placement area A2 of placement unit 52 while moving reading unit 54 with moving unit 56. Then, CPU 101 acquires image data of second side S2 read by reading unit 54 and stores the acquired image data in RAM 103.

[0070] In S113, CPU 101 determines whether or not reading unit 54 has been moved a predetermined distance in the X direction by moving unit 56. If CPU 101 determines that reading unit 54 has moved, it proceeds to S114. On the other hand, if CPU 101 determines that reading unit 54 has not moved, it proceeds to S111. That is, CPU 101 repeats the processes of S111 to S112 until reading unit 54 has moved a predetermined distance that has been set in advance.

[0071] In S114, the CPU 101 turns off the light emitting element 540. In S115, the CPU 101 controls the moving unit 56 to move the reading unit 54 in the direction opposite to the X direction, and moves the reading unit 54 to the initial position.

[0072] Under the control of the CPU 101 described above, image data for both sides of the medium M is stored in the RAM 103. Here, the image data stored in the RAM 103 by the processing of FIG. 10 will be described with reference to FIGS. 12(a) to 12(c). FIGS. 12(a) to 12(c) are schematic diagrams for explaining the image data stored in the RAM 103 by the processing of FIG. 10. In FIGS. 12(a) to 12(c), the image data for the first side S1 of the medium M will be described as "A" and the image data for the second side S2 of the medium M will be described as "B." That is, the image on the first side S1 of the medium M is "A" and the image on the second side S2 is "B." Note that, for the sake of explanation, the memory area is illustrated as a small square cell here, but the actual memory storage unit is much smaller than the cell shown in the figure.

[0073] 12(a) to 12(c), under the control of CPU 101, image data stored in RAM 103 is managed by vertical column addresses and horizontal row addresses. In each diagram, the column addresses increase from 0 to M in the direction of the arrow, and the row addresses increase from 0 to N in the direction of the arrow. Image data read by reading unit 54 is stored at row address 0 in order starting from column address 0. When CPU 101 has finished storing one column's worth of image data, it increments the row address by one row and resumes storing the data in order starting from column address 0.

[0074] 12(a) shows the state of the storage area of ​​RAM 103 when the reading unit 54 starts reading the first side S1 of the medium M placed in the first placement area A1. Since the reading unit 54 has started reading the first side S1, in FIG. 12(a), the image data of the first side S1 of the medium M is stored in the recording area of ​​RAM 103 up to column address M and row address N'. In other words, part of the image data of the image "A" on the first side S1 of the medium M is stored.

[0075] 12(b) shows the state of the storage area of ​​RAM 103 when the reading unit 54 has completed reading the first side S1 of medium M placed in the first placement area A1. Because the reading unit 54 has completed reading the first side S1, in FIG. 12(b), the image data of the first side S1 of medium M is stored in the recording area of ​​RAM 103 up to column address M and row address N / 2. In other words, the entire image data of image "A" on the first side of medium M is stored.

[0076] In conventional image data storage control, once storage of image data for one side of medium M is completed, the data up to that point is considered to be one piece of image data. However, in this embodiment, CPU 101 proceeds to store image data for second side S2 of medium M. Then, when the image on second side S2 is read by reading unit 54, CPU 101 stores the image data for second side S2 in RAM 103 consecutively from the address next to the address last used when storing the image on first side S1 as image data.

[0077] 12(c) shows the state of the storage area of ​​RAM 103 when the reading unit 54 has temporarily stopped and has completed reading the second side S2 of the medium M placed in the second placement area A2. As shown in FIG. 12(c), the column address has progressed to M and the row address to N.

[0078] In this manner, in this embodiment, double-sided reading by the reading unit 54 is performed twice with an interruption in between, but the image data stored in the RAM 103 is a series of continuous data. That is, when reading both sides of the medium M, the CPU 101 stores in the RAM 103 one piece of image data in which a read image of the first side S1 of the medium M and a read image of the second side S2 of the medium M are arranged side by side. By storing the read image of the first side S1 and the read image of the second side S2 as one piece of image data, memory management becomes easier.

[0079] In S116, CPU 101 determines whether the time during which reading unit 54 has been temporarily stopped has passed a predetermined time. If CPU 101 determines that the time has passed, the process proceeds to S117. On the other hand, if CPU 101 determines that the time has not passed, the process proceeds to S107. In other words, CPU 101 determines whether a user instruction to resume movement of moving unit 56 has been received within the predetermined time.

[0080] In S117, CPU 101 turns off light emitting element 540. In S118, CPU 101 controls moving unit 56 to move reading unit 54 from the stop position in the direction opposite to the X direction and return it to the initial position.

[0081] In S119, CPU 101 warns the user that the image reading process will be interrupted. Specifically, CPU 101 may display an error by turning on light-emitting element 541 of display unit 41, or may display an error code on segment display unit 412b. Thereafter, CPU 101 ends this control.

[0082] Second Embodiment The second embodiment will be described below, focusing on the differences from the first embodiment. In the first embodiment, the predetermined distance by which the moving unit 56 moves the reading unit 54 in the X direction is set to less than half the length of the movement path over which the moving unit 56 can move. In this embodiment, when the recording device 1 receives a setting for the size of the medium M to be read, it changes the distance by which the moving unit 56 moves the reading unit 54 in the X direction in accordance with the setting for the size of the medium M to be read.

[0083] The double-sided scanning operation of the recording device 1 in this embodiment will be described below with reference to Fig. 13. Fig. 13 is an explanatory diagram of the double-sided scanning operation of the medium M, and corresponds to a partial perspective view of the scan unit 5. Note that the following processes described in Fig. 13 as being executed by the recording device 1 are realized, for example, by the CPU 101 loading a control program stored in a memory such as the ROM 102 into the RAM 103 and executing it.

[0084] 13 shows a state before the scan unit 5 starts double-sided reading. When the recording device 1 receives a setting operation from the user, it sets the scanning operation of the medium M by the scan unit 5 to double-sided reading mode.

[0085] Furthermore, in this embodiment, when the user presses the numeric setting button 403, the recording device 1 sets the size of the medium M to be read. Then, the recording device 1 changes the distance by which the movement unit 56 moves the reading unit 54 in the X direction according to the setting of the size of the medium M to be read. This allows the reading unit 54 to read double-sided images that correspond to the size of the medium M to be read.

[0086] For example, the recording device 1 may set the length and width of the medium M to be read based on a user operation of the numerical setting button 403. Also, for example, the recording device 1 may store size data for each type of medium M, such as an ID card, business card, or passport, in advance in the RAM 103 or the like. The recording device 1 may then accept a user selection of the type of medium M to be read via the numerical setting button 403. The recording device 1 may then set the size of the medium M based on the type of medium M to be read for which the user selection has been accepted.

[0087] After setting the double-sided reading mode and the size of the medium M to be read, when the recording device 1 receives an instruction from the user to start double-sided reading, it controls each part of the scan unit 5 and starts the double-sided reading operation of the medium M.

[0088] State ST6 in FIG. 13 shows the state when the scan unit 5 starts reading the first side S1 of the medium M. First, the recording device 1 sets the light-emitting element 540 to a full light state. Then, the recording device 1 causes the movement unit 56 to move the reading unit 54 a predetermined distance in the X direction, and causes the reading unit 54 to read an image of the first side S1 of the medium M placed in the first placement area A1. In this embodiment, the predetermined distance is a distance corresponding to the size of the medium M to be read, as set by the recording device 1.

[0089] 13 shows a state when the scan unit 5 has read the first surface S1 of the medium M. When temporarily suspending the movement of the reading unit 54, the recording device 1 sets the light-emitting state of the light-emitting element 540 to an emission state different from the full-light state. When the recording device 1 has moved the reading unit 54 a predetermined distance in the X direction by the moving unit 56, it temporarily suspends the movement of the reading unit 54 by the moving unit 56 between the first placement area A1 and the second placement area A2.

[0090] 13 shows a state when the scan unit 5 starts reading the second side S2 of the medium M. When the recording device 1 receives a user instruction to resume the paused movement of the reading unit 54 in the X direction, the recording device 1 causes the movement unit 56 to resume the movement of the reading unit 54 in the X direction. The recording device 1 causes the movement unit 56 to further move the reading unit 54 in the X direction from the first area A1 by a distance corresponding to the set size of the medium M to be read, and causes the reading unit 54 to read the second side S2 of the medium M placed in the second placement area A2.

[0091] In this embodiment, when the moving unit 56 moves the reading unit 54 in the X direction from the first area A1 by a distance corresponding to the set size of the medium M to be read, the recording device 1 analyzes the read image of the first side S1 and the read image of the second side S2. If the analysis result indicates that double-sided reading has failed, the recording device 1 notifies the user of the failure. For example, the recording device 1 may analyze the edges of the medium M for the read image of the first side S1 and the second read image. If the edges of the medium M are cut, the recording device 1 may notify the user that double-sided reading has failed. Furthermore, the recording device 1 may analyze characters printed on the medium M for the read image of the first side S1 and the read image of the second side S2. If the recording device 1 cannot detect characters printed on the medium M, the recording device 1 may notify the user that double-sided reading has failed. Furthermore, the recording device 1 may notify the user that double-sided reading has failed, for example, if it cannot detect the edges, characters, etc. of the medium M. By notifying the user in this manner, the user can recognize that double-sided reading has failed when double-sided reading of the medium M is performed by moving the reading unit 54 in one direction.

[0092] Thereafter, the recording device 1 causes the movement unit 56 to move the reading unit 54 in the direction opposite to the X direction, and returns the reading unit 54 to the initial position, thereby completing the double-sided reading operation.

[0093] In the present embodiment, the recording device 1 stops the movement of the reading unit 54 by the moving unit 56 when the moving unit 56 has moved the reading unit 54 in the X direction by a distance corresponding to the set size of the medium M to be read, but this is not limited to this. The recording device 1 may start analyzing the read image read by the reading unit 54 while the moving unit 56 is moving the reading unit 54 in the X direction. Then, the recording device 1 may, for example, refer to the storage area of ​​the RAM 103 and stop the movement of the reading unit 54 by the moving unit 56 when it detects a blank portion with no image data.

[0094] Third Embodiment The third embodiment will be described below, focusing on the differences from the first and second embodiments. In the above-described embodiment, when the reading unit 54 is temporarily stopped during double-sided reading of the medium M, the recording device 1 causes the light-emitting element 540 to blink. In this embodiment, when the reading unit 54 is temporarily stopped during double-sided reading of the medium M, the recording device 1 causes the light-emitting element 540 to emit light so as to highlight to the user the position where the medium M should be placed in the second placement area A2 after being inverted.

[0095] The double-sided scanning operation of the recording device 1 in this embodiment will be described below with reference to Fig. 14. Fig. 14 is an explanatory diagram of the double-sided scanning operation of the medium M, and corresponds to a partial perspective view of the scan unit 5. Note that the following processes described in Fig. 14 as being executed by the recording device 1 are realized, for example, by the CPU 101 loading a control program stored in a memory such as the ROM 102 into the RAM 103 and executing it.

[0096] 14 shows the state of the scan unit 5 before the recording device 1 starts double-sided reading by the reading unit 54. Here, the recording device 1 operates in the same manner as the operation described in state ST5 of FIG. 13, for example, and therefore detailed description thereof will be omitted.

[0097] 14 shows the state of the scan unit 5 when the recording device 1 causes the reading unit 54 to start reading the first side S1 of the medium M. Here, the recording device 1 operates in the same manner as the operation described in state ST6 of FIG. 13, for example, and therefore detailed description thereof will be omitted.

[0098] State ST11 in FIG. 14 illustrates the state of the scan unit 5 when the recording device 1 causes the reading unit 54 to read the first side S1 of the medium M. When temporarily suspending the movement of the reading unit 54, the light-emitting element 540 is set to a different light-emitting state from the full-on state. In this embodiment, the recording device 1 uses image data of the first side S1 stored in the RAM 103 to cause the light-emitting element 540 to emit light so as to emphasize the portion of the medium M where the medium M was detected. That is, in this embodiment, the light-emitting element 540 is set to the full-on state when moving, and is set to the full-on state when stopped so as to emphasize the portion 540a corresponding to the position of the medium M in the Y direction in the first placement area A1 more than the other portion 540b. Specifically, the recording device 1 may set the portion 540a of the light-emitting element 540 to a blinking state and the light-emitting element 540b to an off state. Alternatively, for example, the recording device 1 may set the portion 540a of the light-emitting element 540 to an off state and the light-emitting element 540b to a blinking state. Specifically, the recording device 1 may set the light emission intensity of the portion 540a of the light emitting element 540 to be higher than the light emission intensity of the light emitting element 540b. In this way, by changing the light emission state of the light emitting element 540 when it is stopped so that the portion 540a corresponding to the position of the medium M in the Y direction in the first placement area A1 is illuminated more emphatically than the other portion 540b, it is possible to indicate to the user the position at which to flip the medium M to the second placement area.

[0099] (Other embodiments) Furthermore, in each of the above-described embodiments, the recording device 1 receives various user instructions related to the recording device 1 through the operation unit 40, but this is not limited to this. For example, if the recording device 1 is capable of communicating with an external information processing device such as a user's smartphone or PC, the recording device 1 may receive various user instructions related to the recording device 1 from the information processing device. Furthermore, in each of the above-described embodiments, the recording device 1 displays various information related to the recording device 1 to the user through the display unit 41, but this is not limited to this. For example, if the recording device 1 is capable of communicating with an external information processing device such as a user's smartphone or PC, the recording device 1 may display various information related to the recording device 1 through the information processing device.
