Description

Technical Field

[0001] This invention relates to a composite device and a control method for the composite device. Background Technology

[0002] Conventionally, there is a known original document reading device, as shown in Patent Document 1, which has the functions of reading images from original documents and printing images onto printing media. In this original document reading device, there is a reading outlet for discharging the read original document and a printing outlet for discharging the printed printing media, and the reading outlet is arranged above the printing outlet in the vertical direction.

[0003] The original document reading device described in Patent Document 1 has a structure that holds the rear end of the read original document within the reading outlet, and the printing function is stopped while the original document is held. Furthermore, while the original document is held, the printing outlet can be blocked by the original document hanging down from the reading outlet.

[0004] Here, there is a problem that, in a structure that performs both reading and printing functions simultaneously, when the printing medium is ejected while the back end of the original is being held, the front end of the printing medium collides with the original, thus obstructing the ejection of the printing medium and causing a paper jam.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2021-29002 Summary of the Invention

[0006] The composite device includes: a reading mechanism having a reading section for reading information from an original document and an original document outlet for discharging the read original document; a recording mechanism having a recording section for recording information on a recording medium and a medium outlet for discharging the recorded recording medium; and a control unit, wherein the original document outlet is disposed above the medium outlet in a vertical direction, and the path of the top of the recording medium discharged from the medium outlet and the original document discharged from the original document outlet are intersecting at an intersection position, and the control unit is capable of simultaneously performing the reading of the original document by the reading mechanism and the recording of the original document by the recording mechanism. When the discharge of the original document is stopped in a stopped state where the original document discharged from the original document outlet obstructs the path of the top of the recording medium discharged from the medium outlet, and the top of the recording medium is discharged from the medium outlet, the control unit performs a predetermined action to release the stopped state before the top of the recording medium reaches the intersection position.

[0007] In a control method for a composite device, the composite device includes: a reading mechanism having a reading section for reading information from an original document and an original document outlet for discharging the read original document; and a recording mechanism having a recording section for recording information on a recording medium and a medium outlet for discharging the recorded recording medium, wherein the original document outlet is disposed above the medium outlet in a vertical direction, and the path taken by the top of the recording medium discharged from the medium outlet and the original document discharged from the original document outlet are intersecting at a cross-position. Furthermore, it is capable of simultaneously performing the reading of the original document by the reading mechanism and the recording of the recording medium by the recording mechanism. In the control method of the composite device, when the original document discharged from the original document discharge port blocks the forward path of the top of the recording medium discharged from the medium discharge port, causing the discharge of the original document to stop, and the front end of the recording medium is discharged from the medium discharge port, a predetermined action for releasing the stop state is performed before the top end of the recording medium reaches the intersection position.

[0030] 1. First Implementation Method

[0031] First, the structure of the composite device 10 will be described. For example... Figure 1 as well as Figure 2 As shown, the composite device 10 includes a reading mechanism 11 and a recording mechanism 12. The reading mechanism 11 has a reading section 63 for reading information from the original document S and an original document discharge port 64 for discharging the read original document S. The recording mechanism 12 has a recording section 50 for recording information on a recording medium M and a medium discharge port 58 for discharging the recorded recording medium M. Furthermore, the composite device 10 includes a control unit 100 (… Figure 5 The control unit 100 controls the reading mechanism 11 and the recording mechanism 12. The composite device 10 of this embodiment can simultaneously perform the reading of the original document S by the reading mechanism 11 and the recording of the document to the recording medium M by the recording mechanism 12.

[0032] Furthermore, the composite device 10 is positioned on a horizontal plane, and the front-back direction of the composite device 10 is set along the Y-axis, while the left-right direction (or width direction) orthogonal to the Y-axis is set along the X-axis. Additionally, the vertical direction (up-down direction) that is perpendicular to the horizontal plane is set along the Z-axis.

[0033] The composite device 10 has a rectangular box 20. At the bottom of the box 20, there is a base frame 26 that supports the various parts of the composite device 10. The recording unit 50 and the reading unit 63 are housed inside the box 20.

[0034] At the lower part of the composite device 10, a plurality of feet 28 are provided. The feet 28 are connected to the base frame 26 and support the basket 20. The feet 28 are, for example, casters.

[0035] A rectangular opening 31 is provided on the front surface of the housing 20 in the +Y direction, and a space extending in the -Y direction is provided. A feed section 30 is disposed in this space, and a roll body R is disposed on the feed section 30 in a removable manner. The roll body R has a cylindrical shape in which a recording medium M (e.g., paper) is wound in a roll and overlapped on the core member 22. The recording medium M unwound from the roll body R is fed toward the recording section 50. In the feed section 30 of this embodiment, two roll bodies R are housed side by side in the height direction. Both ends of the roll body R are supported by holding members 24 that hold the roll body R in a rotatable manner.

[0036] The composite assembly 10 includes a media transport section 40 within the housing 20. The media transport section 40 transports recording media M unwound from a roll R along a transport path 41. The media transport section 40 includes a transport path forming section 43 and transport rollers 44 (44a, 44b). The transport path forming section 43 is located in the -Y direction relative to the roll R. The transport path forming section 43 forms a roll paper supply channel 42 that guides the recording media M unwound from the roll R towards the -Y direction side of the housing 20. The transport rollers 44 transport the recording media M along the transport path 41. The transport rollers 44 are a pair of rollers supported in a rotatable manner about an axis along the width direction, and are composed of a drive roller and a driven roller. Furthermore, the front and back surfaces of the recording media M are clamped and supported by each drive roller and driven roller. The drive roller is driven to rotate by the forward rotation of the drive motor, thereby conveying the recording medium M through the conveying path 41 to the support part 54, and from the support part 54 to the medium discharge port 58. The medium discharge port 58 is provided on the front surface of the housing 20 in the +Y direction.

[0037] In addition, a media position detection unit 45 is provided, which can detect the position of the top of the recording medium M. The media position detection unit 45 includes, for example, a rotary encoder. This rotary encoder is mounted on a drive motor connected to the drive roller of the conveyor roller 44a. The rotary encoder is connected to the control unit 100. The rotary encoder converts the mechanical displacement of rotation into an electrical signal and processes the signal to detect position or speed, etc.

[0038] The rotary encoder comprises a slit disc fixed to the rotating shaft of a drive motor and position detectors positioned at locations along the periphery of the slit disc. Multiple position detection slits are formed at equal intervals along the periphery of the slit disc, spanning the entire circumference. The position detectors are arranged opposite each other along the periphery of the slit disc, each comprising a light-emitting portion made of a light-emitting diode and a light-receiving portion made of a phototransistor. Furthermore, the encoder is configured such that when light from the light-emitting portion passes through the position detection slits of the slit disc and is received by the light-receiving portion, an electrical signal is output from the light-receiving portion.

[0039] The recording unit 50 records (prints) images on the recording medium M transported along the transport path 41. The recording unit 50 includes: a head 51 that ejects ink toward the recording medium M; a carriage 52 that mounts the head 51; and a guide rail 53 arranged along its width. Furthermore, the recording unit 50 includes a moving mechanism (not shown) that causes the carriage 52 to reciprocate along the guide rail 53. A support portion 54 is provided opposite the head 51 to support the recording medium M. The head 51 ejects ink while reciprocating along the width of the recording medium M with the carriage 52, thereby recording images and other information on the recording medium M supported by the support portion 54.

[0040] Furthermore, a media detection sensor 46 is arranged between the conveyor roller 44a and the head 51 on the conveying path 41. The media detection sensor 46 is a sensor that detects the presence or absence of the recording medium M. The media detection sensor 46 is connected to the control unit 100, and the drive motor connected to the drive roller of the conveyor roller 44a is controlled based on the detection data from the media detection sensor 46. After the recording medium M, which has been cut by the cutting unit 55 (described later), is discharged from the media discharge port 58, the control unit 100 controls the media conveying unit 40, and based on the detection data from the media detection sensor 46, moves the top of the recording medium M to a position upstream of the head 51 and moves the carriage 52 to a standby position.

[0041] The media detection sensor 46 is, for example, a photo interrupter, and includes a light-emitting part that emits light and a light-receiving part that receives light emitted from the light-emitting part. The light-emitting element of the light-emitting part can be, for example, an LED (Light Emitting Diode) or a laser light-emitting element. Furthermore, the light-receiving part is composed of a phototransistor or a photointegrated circuit (Photo IC). The sensor converts the change in the amount of light received between the light-emitting part and the light-receiving part into an electrical signal and outputs it as detection data. The control unit 100 determines the presence or absence of the recording medium M based on the detection data and controls the drive motor of the drive conveyor roller 44a. Additionally, the control unit 100 detects the position of the top of the recording medium M via the media position detection unit 45 (rotary encoder).

[0042] A cutting section 55 is disposed downstream of the recording section 50 in the transport direction. The cutting section 55 cuts the recording medium M after recording has ended. The cutting section 55 has a cutting blade 56, and the cutting blade 56 reciprocates in the width direction (left-right direction) to cut the long strip of recording medium M at a predetermined position.

[0043] The cut, single-sheet recording medium M is discharged from the discharge section 57 in the +Y direction. The discharge section 57 is located downstream of the cutting section 55 in the transport direction. The discharge section 57 includes a medium discharge port 58 and a discharge port member 59. The discharge port member 59 is located in the +Y direction relative to the support section 54, supports the recording medium M that has passed through the support section 54, and guides the recording medium M to the medium discharge port 58. The medium discharge port 58 is formed as an opening above the discharge port member 59. The recording medium M cut by the cutting section 55 is discharged to the outside of the composite device 10 through the medium discharge port 58.

[0044] A stacker 35 is provided between the outlet component 59 and the feed section 30 in the vertical direction. The length of the stacker 35 in the horizontal direction is equal to that of the outlet component 59, and it is configured as a sheet. The stacker 35 is housed inside the housing 20 and is movable in the +Y direction. When using the stacker 35, it is used in a state where it is pulled out in the +Y direction and flexed. In this state, the recording medium M, which has been cut, is discharged from the medium outlet 58, thereby loading the recording medium M onto the stacker 35.

[0045] An ink cartridge 39 is provided inside the housing 20. The ink cartridge 39 stores the ink. The ink cartridge 39 is detachable relative to the cartridge holder 38. The user can replace the ink cartridge 39 from the front surface of the composite device 10. The ink stored in the ink cartridge 39 is supplied to the head 51 through a hose.

[0046] A reading mechanism 11 is disposed above the front side inside the housing 20. A document feed port 61 is provided at the front of the +Z direction end face (upper surface) of the housing 20. The document feed port 61 is an opening extending along the X-axis. The document S is fed into the reading mechanism 11 via the document feed port 61, and reading processing is performed to read the information of the document S by the reading unit 63. The document S that has undergone reading processing is discharged from the document discharge port 64 to the outside of the housing 20. The structure of the reading mechanism 11 will be described later.

[0047] On the upper surface of the housing 20, an operation unit 15 is provided for issuing operation instructions to the composite device 10. The operation unit 15 is equipped with a display panel such as an LCD. The operation unit 15 is equipped with a tilt mechanism, so it can also be used in a tilted position that facilitates operation of the operation unit 15.

[0048] Next, the structure of the reading mechanism 11 will be explained.

[0049] like Figure 3As shown, the reading mechanism 11 includes: a document feed port 61 for inserting a document S; a document transport unit 62 for transporting the document S inserted from the document feed port 61 along the transport path FR; a reading unit 63 for reading information such as images of the document S transported by the document transport unit 62; a pressing mechanism 85 for pressing the document S toward the reading unit 63; a document discharge port 64 for discharging the document S after reading; and a sensor unit 65 for detecting the document S.

[0050] The transport path FR, extending from the original document feed port 61 to the original document discharge port 64, is inclined in the -Z direction along the +Y direction. The discharge direction of the original document S in the original document discharge port 64, i.e., the first discharge direction D1, is a direction that includes a component of the +Y direction. Specifically, the transport path FR is inclined at a predetermined angle that is acute relative to the -Z direction. As a result, the original document S discharged from the original document discharge port 64 will move away from the original document discharge port 64. In particular, if the tip portion of the original document S discharged from the original document discharge port 64 is curled, when the tip portion approaches the media discharge port 58, the tip portion may enter the interior of the composite device 10 from the media discharge port 58. By making the first discharge direction D1 include a component of the +Y direction, the possibility of the original document S entering the interior of the composite device 10 from the media discharge port 58 is reduced.

[0051] The original document transport unit 62 includes: an upstream drive roller pair 71; a first drive roller pair 72 disposed downstream of the upstream drive roller pair 71 on the transport path FR; and a second drive roller pair 73 disposed downstream of the first drive roller pair 72 on the transport path FR. The upstream drive roller pair 71, the first drive roller pair 72, and the second drive roller pair 73 all transport the original document S in a clamping manner. The reading unit 63 is disposed between the upstream drive roller pair 71 and the first drive roller pair 72 on the transport path FR. Furthermore, the original document transport unit 62 includes a reading transport motor 62M (see reference) that drives the upstream drive roller pair 71, the first drive roller pair 72, and the second drive roller pair 73. Figure 5 In addition, in this embodiment, "upstream" on the transport path FR means upstream in the transport direction from the original document feed port 61 to the original document discharge port 64. Similarly, "downstream" on the transport path FR means downstream in the transport direction from the original document feed port 61 to the original document discharge port 64.

[0052] The upstream drive roller pair 71 is located upstream of the readable position SP of the reading unit 63 on the conveying path FR, and includes an upstream drive roller 74 and an upstream driven roller 75. The upstream drive roller 74 is rotatably supported about the axis of an upstream drive shaft 741 extending along the X-axis. The outer peripheral surface of the upstream drive roller 74 is covered by a component capable of elastic deformation. For example, the outer peripheral surface of the upstream drive roller 74 is covered with synthetic rubber. The upstream drive roller 74 is driven by a conveying motor 62M. The upstream driven roller 75 is rotatably supported about the axis of an upstream driven shaft 751 extending along the X-axis. The axes of the upstream drive shaft 741 and the upstream driven shaft 751 are substantially parallel.

[0053] The first drive roller pair 72 is located downstream of the readable position SP of the reading unit 63 on the conveying path FR, and includes a first drive roller 76 and a first driven roller 77. The first drive roller 76 is rotatably supported about the axis of a first drive shaft 761 extending along the X-axis. The first drive roller 76 is driven by a conveying motor 62M. The first driven roller 77 is rotatably supported about the axis of a first driven shaft 771 extending along the X-axis. The axes of the first drive shaft 761 and the first driven shaft 771 are substantially parallel.

[0054] The second drive roller pair 73 is located downstream of the readable position SP of the reading unit 63 on the conveying path FR, and includes a second drive roller 78 and a second driven roller 79. The second drive roller 78 is rotatably supported about the axis of a second drive shaft 781 extending along the X-axis. The second drive roller 78 is driven by a conveying motor 62M. The second driven roller 79 is rotatably supported about the axis of a second driven shaft 791 extending along the X-axis. The axes of the second drive shaft 781 and the second driven shaft 791 are substantially parallel.

[0055] In the reading unit 63 of this embodiment, a first CIS module 80A and a second CIS module 80B are included as a contact image sensor (CIS) module 80. The CIS module 80 includes a light source 801 such as an LED that illuminates the original document S, a light-receiving element 802 such as a CMOS sensor that receives reflected light from the transported original document S, and a contact glass 803 that contacts the original document S. The original document S is transported while in contact with the transmissive surface 804 of the contact glass 803. The light source 801 illuminates the original document S through the contact glass 803, and the light-receiving element 802 reads the reflected light from the original document S.

[0056] The control of the light source 801 and the light-receiving element 802 of the CIS module 80 can be implemented either by the control unit 100 or by a dedicated control unit such as a microprocessor provided in the CIS module 80. Based on the reading results of the light-receiving element 802 of the CIS module 80, image data is synthesized and generated by the control unit 100.

[0057] In the CIS module 80 of this embodiment, the light-receiving elements 802 are arranged along the X-axis. The CIS module 80 reads the opposite portion of the original S at a time within a range of its dimensions along the X-axis. In this embodiment, the first CIS module 80A and the second CIS module 80B partially overlap each other on the X-axis.

[0058] In the reading mechanism 11 of this embodiment, the pressing mechanism 85 includes a pressing mechanism 85A that applies force in the direction of pressing the original document S onto the contact glass 803 of the first CIS module 80A, and a pressing mechanism 85B that applies force in the direction of pressing the original document S onto the contact glass 803 of the second CIS module 80B. The pressing mechanism 85 is provided at a position between the upstream drive roller pair 71 and the first drive roller pair 72 in the conveying direction of the original document S, where the original document S can be pressed.

[0059] The pressing mechanism 85 has a pressing plate 86 that can contact the original document S, and a pressing spring 87 that applies force to the pressing plate 86 in a direction approaching the transmission surface 804. The pressing plate 86 of the pressing mechanism 85A is opposite to the transmission surface 804 of the first CIS module 80A across the transport path FR. The pressing plate 86 of the pressing mechanism 85B is opposite to the transmission surface 804 of the second CIS module 80B across the transport path FR.

[0060] The original discharge outlet 64 is the space sandwiched between the discharge guide 88 and the wall 681 that is opposite to the discharge guide 88 across the transport path FR.

[0061] The sensor unit 65 includes a first sensor 651 capable of detecting the original document S, and a second sensor 652 capable of detecting the original document S at a different position than the first sensor 651. The detection position, i.e., the first detection position DP1, performed by the first sensor 651, is located upstream of the original document S in the transport direction relative to the transmittance surface 804 of the first CIS module 80A. When the original document S is located at the first detection position DP1, the first sensor 651 detects the original document S; when the original document S is not located at the first detection position DP1, the first sensor 651 does not detect the original document S. The detection position, i.e., the second detection position DP2, performed by the second sensor 652, is located downstream of the second drive roller pair 73 in the transport direction relative to the original document S. When the original document S is located at the second detection position DP2, the second sensor 652 detects the original document S; when the original document S is not located at the second detection position DP2, the second sensor 652 does not detect the original document S.

[0062] The discharge guide 88 is disposed on the -Z direction side relative to the second drive roller pair 73. The discharge guide 88 is a plate-shaped component extending along the X-axis. The discharge guide 88 has a guide surface 881 facing the +Z direction. The guide surface 881 is inclined in a manner that decreases towards the -Z direction as it moves towards the +Y direction. The discharged manuscript S is discharged along the guide surface 881. That is, the first discharge direction D1, which is the direction in which the manuscript S is discharged, is a direction that decreases towards the -Z direction as it moves towards the +Y direction.

[0063] like Figure 4 As shown, the first conveying direction FD1, which is the conveying direction of the original document S in the clamping position N1 of the first drive roller pair 72, is a direction that includes more components in the vertical downward -Z direction than in the +Y direction. Furthermore, in this embodiment, the first conveying direction FD1 is along the direction of the tangent to the first drive roller 76 passing through the clamping position N1. In this embodiment, the clamping position N1 can be considered as the intersection of the straight line connecting the center of the first drive shaft 761 and the center of the first driven shaft 771 with the outer peripheral surface of the first drive roller 76.

[0064] The second conveying direction FD2, which is the conveying direction of the original document S in the clamping position N2 of the second drive roller pair 73, is a direction in which the component in the vertical downward -Z direction is greater than the component in the +Y direction. Further, the ratio of the +Y component to the vertical downward -Z component in the second conveying direction FD2 is greater than the ratio of the +Y component to the vertical downward -Z component in the first conveying direction FD1. In this embodiment, the second conveying direction FD2 is a direction along the tangent of the second drive roller 78 passing through the clamping position N2. In this embodiment, the clamping position N2 can be considered as the intersection of the straight line connecting the center of the second drive shaft 781 and the center of the second driven shaft 791 with the outer peripheral surface of the second drive roller 78.

[0065] The first unit feed amount of the original document S that the first drive roller 76 can transport in one rotation is greater than the second unit feed amount of the original document S that the second drive roller 78 can transport in one rotation. That is, the circumferential speed of the second drive roller 78 is less than the circumferential speed of the first drive roller 76. The difference in circumferential speed between the first drive roller 76 and the second drive roller 78 is set according to the roller diameter in this embodiment. Specifically, in this embodiment, the diameter of the second drive roller 78 is smaller than the diameter of the first drive roller 76, and the first drive roller 76 and the second drive roller 78 are driven at the same rotational speed by the conveyor motor 62M. Therefore, the circumferential speed of the second drive roller 78 is less than the circumferential speed of the first drive roller 76. Although the roller diameters of the first drive roller 76 and the second drive roller 78 are different in this embodiment, any structure in which the first unit feed amount of the first drive roller 76 is greater than the second unit feed amount of the second drive roller 78 is acceptable. For example, the structure could be such that the first drive roller 76 and the second drive roller 78 have the same diameter, and the rotational speed of the first drive roller 76 is greater than the rotational speed of the second drive roller 78. Alternatively, the structure could have different roller diameters and rotational speeds.

[0066] Since the second unit feed of the second drive roller 78 is smaller than the first unit feed of the first drive roller 76, the second drive roller pair 73 will not pull the original document S downstream. Therefore, deviations in the conveying speed at the readable position SP of the original document S caused by the conveying force when the second drive roller pair 73 conveys the original document S can be suppressed.

[0067] Furthermore, the clamping force formed by the second drive roller 78 and the second driven roller 79 constituting the second drive roller pair 73 is less than the clamping force formed by the first drive roller 76 and the first driven roller 77 constituting the first drive roller pair 72.

[0068] The first driven roller 77, constituting the first drive roller pair 72, is forced in the direction toward the first drive roller 76 by the first spring 831. Therefore, the clamping force of the first drive roller pair 72 holding the original document S is determined by the applied force of the first spring 831. The first spring 831 is a compression spring. In addition, the first spring 831 is not limited to a compression spring; it can be any spring capable of applying force to the first driven roller 77, such as a cylindrical spring.

[0069] The second driven roller 79, constituting the second drive roller pair 73, is forced in the direction toward the second drive roller 78 by the second spring 841. Therefore, the clamping force of the second drive roller pair 73 holding the original manuscript S is determined by the applied force of the second spring 841. The second spring 841 is a cylindrical spring. However, the second spring 841 is not limited to a cylindrical spring; it can be any spring capable of applying force to the second driven roller 79, such as a compression spring.

[0070] The spring constant of the second spring 841 is smaller than that of the first spring 831. In other words, the second spring 841 applies a smaller force compared to the first spring 831. Therefore, the clamping force of the second drive roller pair 73 is weaker than that of the first drive roller pair 72.

[0071] Next, the control structure of the composite device 10 will be explained.

[0072] like Figure 5 As shown, the composite device 10 includes a control unit 100. The control unit 100 includes a CPU 101, a memory 102, a control circuit 103, and an I / F (interface) 104. The CPU 101 is an arithmetic processing unit. The memory 102 is a device for storing programs of the CPU 101 or for ensuring working areas, and includes storage elements such as RAM and EEPROM.

[0073] The control unit 100 is connected to the operation unit 15. When the operation unit 15 is operated, the operation signal output is input to the control unit 100. When a predetermined operation is performed on the operation unit 15, the operation unit 15 outputs a read request signal. When this read request signal is input to the control unit 100, the control unit 100 accepts the read request. Upon accepting the read request, the control unit 100 controls the reading mechanism 11 and the recording mechanism 12. The reading unit 63 of the reading mechanism 11 reads the image of the original document S and generates image data, and the recording mechanism 12 records the image based on the generated image data onto the recording medium M.

[0074] A sensor unit 65 is electrically connected to the control unit 100. The control unit 100 determines the state of the original document S based on changes in the output of the sensor unit 65.

[0075] The first sensor 651 is electrically connected to the control unit 100, serving as a sensor unit 65 electrically connected to the control unit 100. The output implemented by the first sensor 651 when it detects the original document S is a first output, and the output implemented by the first sensor 651 when it does not detect the original document S is a second output. When the output implemented by the first sensor 651 changes from the second output to the first output, the control unit 100 determines that the top of the original document S has passed the first detection position DP1. When the top of the original document S passes the first detection position DP1, the control unit 100 starts counting the rotation amount of the transport motor 62M using a counter (not shown). The control unit 100 synthesizes the reading result read by the light-receiving element 802 of the reading unit 63 based on the position of the original document S inferred from the count value.

[0076] Furthermore, when the output implemented by the first sensor 651 changes from the first output to the second output, the control unit 100 determines that the rear end of the original document S has passed the first detection position DP1. When the rear end of the original document S passes the first detection position DP1, the control unit 100 starts counting the counter. The control unit 100 performs the original document S holding operation, which will be described later, based on the position of the rear end of the original document S inferred from the count value.

[0077] The second sensor 652 is electrically connected to the control unit 100, serving as a sensor unit 65 electrically connected to the control unit 100. The output implemented by the second sensor 652 when the original document S is detected is a third output, and the output implemented by the second sensor 652 when the original document S is not detected is a fourth output. During the original document S holding operation (described later), the second sensor 652 detects the original document S being held by the second drive roller pair 73. During the original document S holding operation, when the output implemented by the second sensor 652 changes from the third output to the fourth output, the control unit 100 determines that the original document S being held by the second drive roller pair 73 has been removed from the composite device 10.

[0078] Furthermore, the control unit 100 is configured to enable bidirectional communication with an external device (e.g., a personal computer) via the I / F 104. The control unit 100 can input record request signals, read request signals, and read request signals output by the external device connected to the I / F 104. Additionally, the I / F 104 can be configured to enable either a wired or wireless connection.

[0079] Next, the control method involved in the holding operation of the original document S in the reading mechanism 11 will be described. In detail, when the original document S discharged from the original document discharge port 64 accidentally falls downwards, the original document S may be deformed. Therefore, in this embodiment, a holding operation is performed in the reading mechanism 11 to hold the original document S discharged from the original document discharge port 64.

[0080] The following is a detailed explanation.

[0081] like Figure 6 As shown, firstly, in step S11, the control unit 100 executes the reading and recording processes. Specifically, when a reading request is received, the conveyor motor 62M is controlled to rotate the upstream drive roller pair 71, the first drive roller pair 72, and the second drive roller pair 73, thereby initiating the conveying of the original document S inserted into the original document feed port 61. After the conveying of the original document S begins, the control unit 100 controls the reading unit 63 so that the image (information) of the original document S is read when the original document S passes the readable position SP.

[0082] In step S12, the control unit 100 determines whether the rear end of the original document S has passed the first detection position DP1 after the original document S began to be transported in step S11. More specifically, it monitors the change in the output implemented by the first sensor 651 from a first output indicating that the original document S has been detected to a second output indicating that the original document S has not been detected. When the output implemented by the first sensor 651 changes from the first output to the second output (yes), the control unit 100 determines that the rear end of the original document S has passed the first detection position DP1.

[0083] The control unit 100 controls the light sources 801 of each CIS module 80 by irradiating the original document S with white light. The control unit 100 receives inputs from the results detected by multiple light-receiving elements 802 through red, blue, and green color filters. As described above, when the top of the original document S passes the first detection position DP1, a counter is used to start counting the rotation amount of the transport motor 62M (step S13). The control unit 100 generates image data, such as text and images, recorded on the original document S by synthesizing the detection results detected by the light-receiving elements 802 of the multiple CIS modules 80 based on the count value counted by the counter. Furthermore, the control unit 100 stores the generated image data in the memory 102.

[0084] Furthermore, the control unit 100 records image data stored in the memory 102 onto the recording medium M via the recording mechanism 12. Specifically, the control unit 100 controls the media transport unit 40 to transport the recording medium M. Then, the control unit 100 controls the recording unit 50 to eject ink onto the recording medium M as it passes the recording position where recording is performed by the recording unit 50. Thus, image data is recorded onto the recording medium M. The control unit 100 then discharges the recording medium M, with the recorded image data, toward the media discharge port 58.

[0085] In step S14, the control unit 100 determines whether the count value counted by the counter exceeds a preset value (step S14).

[0086] Here, the predetermined value used in the determination in step S14 is a value on the transport path FR corresponding to the length between the first detection position DP1 and the clamping position N1 detected by the first sensor 651. More specifically, the predetermined value is set based on the length between the first detection position DP1 and the clamping position N1 on the transport path FR and the circumferential speed of the first drive roller 76. Therefore, the predetermined value is set as the value at which the rear end of the original document S is located at the clamping position N1 after the count value reaches the predetermined value after the rear end of the original document S passes the first detection position DP1. Therefore, the determination in step S14 implemented by the control unit 100 can also be regarded as a determination of whether the rear end of the original document S has passed the clamping position N1.

[0087] When the control unit 100 determines that the count value counted by the counter exceeds a predetermined value (Yes), it stops the counter counting (step S15) and controls the conveyor motor 62M to stop the conveying of the original document S (step S16). Therefore, when the original document S is not located at the readable position SP of the reading unit 63 and is not located at the clamping position N1, the control unit 100 stops the rotation of the upstream drive roller pair 71, the first drive roller pair 72, and the second drive roller pair 73. In step S16, the control unit 100 stops the conveying of the original document S before the rear end of the original document S passes the clamping position N2 of the second drive roller pair 73. In addition, although in this embodiment, the control unit 100 executes step S16 after executing step S15, it is possible to execute step S16 before the rear end of the original document S passes the clamping position N2, or to execute step S16 before step S15, or to execute step S15 and step S16 in parallel.

[0088] When the control unit 100 stops the transport of the original document S in step S16, such as Figure 7As shown, the original document S will not fall from the original document outlet 64 but will be held by the composite device 10. More specifically, the original document S is held on the reading mechanism 11 (composite device 10) in a state where it is held near the rear end of the original document S by the second drive roller pair 73 and the top end of the original document S is facing downwards, hanging from the original document outlet 64. Thus, it is possible to prevent the original document S, whose image has been read by the reading unit 63, from accidentally falling from the original document outlet 64.

[0089] Here, the positional relationship between the original document discharge port 64 of the reading mechanism 11 and the media discharge port 58 of the recording mechanism 12 will be explained.

[0090] like Figure 8 As shown, the original document discharge port 64 is positioned above the media discharge port 58 in the vertical direction. Furthermore, the forward path MD2, through which the top of the recording medium M discharged from the media discharge port 58 passes, and the original document S discharged from the original document discharge port 64 are intersecting at the intersection position CP.

[0091] The first forward path MD1 through which the top of the original document S is discharged from the original document discharge outlet 64 is a first discharge direction D1 and a -Z direction that includes a component of the +Y direction when the top of the original document S is being transported on the discharge guide 88. Thereafter, when the top of the original document S is discharged from the original document discharge outlet 64 to the outside, it becomes a -Z direction.

[0092] On the other hand, the second forward path MD2 through which the top of the recording medium M is discharged from the media outlet 58 is the second discharge direction D2 and is approximately +Y direction (horizontal direction) when the top of the recording medium M is being transported on the outlet member 59 and supported thereafter. Afterward, when the top of the recording medium M is discharged from the media outlet 58 to the outside, it becomes -Z direction.

[0093] The intersection position CP of the original S and the recording medium M is the intersection of the first forward path MD1 through which the top of the original S passes and the second forward path MD2 through which the top of the recording medium M passes, and is approximately along the upper surface of the discharge port component 59, and is located in the +Y direction of the discharge port component 59.

[0094] Therefore, when the top of the original S is at the cross position CP, and the recording medium M is ejected along the second ejection direction D2, the original S will block the second forward path MD2 of the top of the recording medium M. That is, the positions where the top of the original S is at the cross position CP and where the top of the original S is located below the cross position CP will become the positions that block the second forward path MD2 of the top of the recording medium M.

[0095] Furthermore, for the composite device 10 of this embodiment, the angle of the first discharge direction D1 of the original in the reading mechanism 11 relative to the original in the horizontal original discharge port 64, i.e., the first angle θ1, is greater than the angle of the second discharge direction D2 of the recording medium M in the recording mechanism 12 relative to the recording medium in the horizontal medium discharge port 58, i.e., the second angle θ2.

[0096] That is, in the composite device 10 which has a reading mechanism 11 and a recording mechanism 12, since the original document S is held facing downwards instead of being discharged and held horizontally, it is possible to suppress the occurrence of damage or creases on the original document S.

[0097] On the other hand, when the original manuscript S has been held in place, that is, when the original manuscript S is hanging down from the original manuscript outlet 64, the top of the original manuscript S is below the intersection position CP, as shown below. Figure 7 As shown, the media outlet 58 for discharging the recording medium M is blocked by the held original document S, thereby obstructing the second forward path MD2 of the top of the recording medium M. In this manner, when the media outlet 58 is blocked by the original document S, the top of the discharged recording medium M will come into contact with the original document S when it is discharged from the media outlet 58. Furthermore, since the discharge operation of the recording medium M is performed while its movement in the +Y direction is hindered by the original document S, the recording medium M will become blocked within the housing 20, resulting in a paper jam.

[0098] Therefore, in the control unit 100 of the composite device 10 in this embodiment, the reading mechanism 11 and the recording mechanism 12 are controlled in order to suppress such transmission failures.

[0099] Specifically, when the control unit 100 discharges the top of the recording medium M from the media outlet 58 while the discharge of the original document S from the original document outlet 64 is stopped at a position where the discharge of the original document S is blocked by the second forward path MD2 of the top of the recording medium M discharged from the media outlet 58, a predetermined action for releasing the stop state is performed before the top of the recording medium M reaches the cross position CP. The stop state refers to, for example, a state in which a holding action is performed to hold the original document S discharged from the original document outlet 64. Furthermore, the position where the second forward path MD2 of the original document S discharged from the original document outlet 64 blocks the top of the recording medium M is a state where the top of the original document S discharged from the original document outlet 64 is located below the cross position CP. In other words, the position where the original S discharged from the original discharge port 64 blocks the second forward path MD2 of the top of the recording medium M refers to the position where the original S blocks the media discharge port 58 when viewed from the -Y direction. Therefore, if the top of the recording medium M is discharged towards the media discharge port 58 while the original S is stopped, it may cause a paper jam.

[0100] The specific control methods are explained below. Additionally, due to... Figure 9 Steps S101 to S106 in the process Figure 6 Steps S11 to S16 are the same, so the explanation is omitted.

[0101] like Figure 9 As shown, in step S107, the control unit 100 determines whether the tip of the recording medium M has been discharged from the media outlet 58. Specifically, the control unit 100 determines whether the tip of the recorded recording medium M is near the media outlet 58. Specifically, the control unit 100 detects the position of the tip of the recording medium M based on the detection data from the media position detection unit 45. Furthermore, since the position of the media outlet 58 is known, it is easy to determine whether the tip of the recording medium M is near the media outlet 58 by detecting the position of the tip of the recording medium M.

[0102] Then, as Figure 10 As shown, if the control unit 100 determines that the top of the recording medium M is near the media outlet 58 while the original document S is stopped (yes), it will proceed to step S108. On the other hand, if the control unit 100 determines that the top of the recording medium M is not near the media outlet 58 (no), it will proceed to step S106 and continue the recording operation.

[0103] In step S108, when the rear end of the original document S is held by the second drive roller 78, the control unit 100 performs a predetermined action to release the stop state, and discharges the original document S via the second drive roller 78, which acts as a discharge roller. Specifically, the control unit 100 drives the conveyor motor 62M. Thus, as... Figure 11 As shown, the second drive roller 78 rotates, thereby releasing the original document S held at the clamping position N2 of the second drive roller pair 73, and causing the entire original document S to be discharged from the original document discharge port 64. This releases the stop state and opens the media discharge port 58. Then, as... Figure 12 As shown, the recording operation continues, causing the recording medium M to be discharged from the medium discharge port 58. Furthermore, the recording operation that discharges the recording medium M also includes the operation of simply conveying the recording medium M.

[0104] According to this embodiment, the stop state of the original S is released before the top of the recording medium M reaches the intersection position CP. Specifically, the stop state of the original S is released by driving the second drive roller 78. As a result, since there is no situation where the original S blocks the second forward path MD2 of the recording medium M, the discharge of the recording medium M can be carried out smoothly without the recording medium M colliding with the original S.

[0105] Furthermore, although in this embodiment the stop state is released by driving the second drive roller 78, it is not limited to this. For example, it can also be structured such that the distance between the second drive roller 78 and the second driven roller 79 in the second drive roller pair 73 is configured to be able to be displaced to the clamping position N2 of the original document S and the open position of the clamping state of the original document S, and the stop state is released by displacing to the open position of the clamping state of the original document S.

[0106] 2. Second Implementation Method

[0107] Next, the second embodiment will be described. Furthermore, structures identical to those in the first embodiment will be labeled with the same symbols, and repeated descriptions will be omitted.

[0108] Figure 13 The control method of the composite device 10 according to this embodiment will be described. Furthermore, since the content of steps S201 to S207 is the same as steps S101 to S107 of the first embodiment (…),… Figure 9 Since they are the same, the explanation is omitted.

[0109] like Figure 13As shown, in step S207, if the control unit 100 determines that the top of the recording medium M is near the media outlet 58 while the original document S is stopped (Yes), it proceeds to step S208. On the other hand, if the control unit 100 determines that the top of the recording medium M is not near the media outlet 58 (No), it proceeds to step S206 and the recording operation continues.

[0110] In step S208, before the top of the recording medium M discharged from the medium outlet 58 reaches the cross position CP, the control unit 100 performs a predetermined action to release the stop state, and transports the original S in the direction opposite to the first discharge direction D1 until it reaches the position of the second forward path MD2 that does not obstruct the top of the recording medium M.

[0111] Specifically, such as Figure 14 As shown, from the stop state where the original document S is stopped at the position of the second forward path MD2 that blocks the top of the recording medium M, the transport motor 62M is driven. In this embodiment, the transport motor 62M is driven in reverse rotation. Thus, as Figure 15 As shown, the upstream drive roller 74, the first drive roller 76, and the second drive roller 78 rotate in reverse, thereby conveying the original document S in the opposite direction to the first discharge direction D1. For example, when the rear end of the original document S reaches the detection position DP1 detected by the first sensor 651, the control unit 100 stops the drive of the conveyor motor 62M. This releases the stop state and opens the media outlet 58. Then, as... Figure 16 As shown, the recording operation continues, and the recording medium M is discharged from the medium discharge port 58. Alternatively, the control unit 100 may be configured such that, by detecting the rotation amount of the conveying motor 62M, the position of the top of the original document S is detected, and the original document S is conveyed in the opposite direction to the first discharge direction D1 until the position of the top of the original document S no longer obstructs the position of the second forward path MD2 of the top of the recording medium M.

[0112] In step S209, the control unit 100 determines whether the tip of the recording medium M has been discharged from the media outlet 58. Specifically, the control unit 100 determines whether the tip of the recorded recording medium M has been discharged from the media outlet 58 to the outside. Specifically, the control unit 100 detects the position of the tip of the recording medium M based on the detection data from the media position detection unit 45. Furthermore, since the position of the media outlet 58 is known, it is easy to determine whether the tip of the recording medium M is located further outward than the media outlet 58 by detecting the position of the tip of the recording medium M.

[0113] If the control unit 100 determines that the top of the recording medium M has been discharged to the outside from the medium discharge port 58 (yes), in step S210, as follows: Figure 16 As shown, the control unit 100 drives the conveyor motor 62M to rotate forward, and discharges the original document S along the first discharge direction D1. Furthermore, since the top of the recording medium M has already passed the intersection position CP, the risk of paper jams is low because the top of the recording medium M will be discharged along the second forward path MD2 even after the original document S is discharged.

[0114] According to this embodiment, since the original document S is conveyed in the opposite direction to the first discharge direction D1 before the top of the recording medium M reaches the intersection position CP, the second forward path MD2 of the recording medium M will not be obstructed. Therefore, the recording medium M can be discharged smoothly. Furthermore, since the original document S will not fall from the original document discharge outlet 64, damage to the original document S can be suppressed.

[0115] Furthermore, users can make appropriate choices regarding this embodiment and the first embodiment.

[0116] 3. Third Implementation Method

[0117] Next, the third embodiment will be described. Furthermore, structures identical to those in the first embodiment will be labeled with the same symbols, and repeated descriptions will be omitted.

[0118] exist Figure 17 The control method of the composite device 10 according to this embodiment will be described. Furthermore, since the content of steps S301 to S308 is the same as steps S101 to S108 of the first embodiment... Figure 9 Since they are the same, the explanation is omitted.

[0119] In this embodiment, when the recording medium M is discharged from the medium discharge port 58 in the discharge state where the original document S has been discharged, the control unit 100 discharges the recording medium M toward the intersection position CP even when the original document S blocks the second forward path MD2 at the top of the recording medium M.

[0120] The following is a detailed explanation.

[0121] In step S304, the control unit 100 determines whether the count value performed by the counter exceeds a predetermined value. If it determines that the count value performed by the counter exceeds the predetermined value (yes), it proceeds to step S305. On the other hand, if it determines that the count value performed by the counter does not exceed the predetermined value (no), it proceeds to step S309.

[0122] Here, the determination by the control unit 100 in step S304 can be seen as a determination of whether the rear end of the original document S has passed the clamping position N1. That is, the situation where the count value performed by the counter does not exceed the predetermined value means that, for example... Figure 18 As shown, the original document S is located upstream of the clamping position N1 on the transport path FR, and is being transported downstream of the transport path FR during the period until the count value determined by the counter exceeds a predetermined value. That is, the original document S is in the discharge state. In addition, the discharge state can be either the original document S being read or only in the discharge process.

[0123] In step S309, the control unit 100 determines whether the tip of the recording medium M has been discharged from the media outlet 58. Specifically, the control unit 100 determines whether the tip of the recorded recording medium M is near the media outlet 58. Specifically, the control unit 100 detects the position of the tip of the recording medium M based on the detection data from the media position detection unit 45. Then, if the control unit 100 determines that the tip of the recording medium M is near the media outlet 58 while the original document S is stopped (Yes), it proceeds to step S310. On the other hand, if the control unit 100 determines that the tip of the recording medium M is not near the media outlet 58 (No), it proceeds to step S303.

[0124] In step S310, the control unit 100 continues the transport of the recording medium M. Specifically, the control unit 100 controls the recording mechanism 12 to perform the recording operation on the recording medium M and to transport the recording medium M.

[0125] That is, such as Figure 19 As shown, in step S310, the discharge of the original document S and the discharge of the recording medium M are performed simultaneously. In this case, due to the discharge of the original document S, the original document S blocks the medium discharge outlet 58 through the cross position CP, and in this state, the recording medium M comes into contact with the original document S. However, since the recording medium M comes into contact with the original document S, which is being discharged downward along the first forward path MD1, the propulsive force accompanying the downward movement of the original document S promotes the discharge of the recording medium M, and thus the recording medium M is discharged downward together with the original document S.

[0126] According to this embodiment, after the recording medium M collides with the original document S, it is ejected along with the ejection of the original document S. Therefore, paper jams in the recording medium M can be reduced, and the ejection of the original document S and the ejection of the recording medium M can be performed simultaneously, thereby improving the throughput of the recording process.

[0127] 4. Fourth Implementation Method

[0128] Next, the fourth embodiment will be described. Furthermore, structures identical to those in the first embodiment will be marked with the same symbols, and repeated descriptions will be omitted.

[0129] exist Figure 20 The control method of the composite device 10 according to this embodiment will be described in this section. Furthermore, since the content of steps S401 to S408 is the same as steps S101 to S108 of the first embodiment (…),… Figure 9 Since they are the same, the explanation is omitted.

[0130] In this embodiment, when the top of the recording medium M passes the cross position CP before the original S reaches the position of the blockage medium discharge outlet 58, the control unit 100 performs the discharge of the original S and the discharge of the recording medium M simultaneously.

[0131] The following is a detailed explanation.

[0132] In step S404, the control unit 100 determines whether the count value performed by the counter exceeds a predetermined value. If it determines that the count value performed by the counter exceeds the predetermined value (yes), it proceeds to step S405. On the other hand, if it determines that the count value performed by the counter does not exceed the predetermined value (no), it proceeds to step S409.

[0133] Here, the determination by the control unit 100 in step S404 can be seen as a determination of whether the rear end of the original document S has passed the clamping position N1. That is, the situation where the count value performed by the counter does not exceed the predetermined value means that, for example... Figure 21 As shown, the document S is being conveyed downstream of the transport path FR at a position upstream of the clamping position N1, and during the period until the count value determined by the counter exceeds a predetermined value. That is, the document S is in a state before reaching the blockage medium discharge port 58. This state can be either the document S being read, or only during the discharge process. Furthermore, it can also be a state where the document S has stopped.

[0134] In step S409, the control unit 100 determines whether the tip of the recording medium M has been discharged from the media outlet 58. Specifically, the control unit 100 determines whether the tip of the recorded recording medium M has been discharged to the outside from the media outlet 58. Specifically, the control unit 100 detects the position of the tip of the recording medium M based on the detection data from the media position detection unit 45. Then, if the control unit 100 determines that the tip of the recording medium M has been discharged from the media outlet 58 (yes), it proceeds to step S410. On the other hand, if the control unit 100 determines that the tip of the recording medium M has not been discharged from the media outlet 58 (no), it proceeds to step S403.

[0135] In step S410, the control unit 100 continues the transport of the recording medium M. Specifically, the control unit 100 controls the recording mechanism 12 to perform the recording operation on the recording medium M and to transport the recording medium M.

[0136] That is, such as Figure 22 As shown, in step S410, the discharge of the original S and the discharge of the recording medium M continue. In this case, although the original S may block the media discharge outlet 58 due to the discharge of the original S via the cross position CP, the top of the recording medium M has already been discharged from the media discharge outlet 58. Therefore, since the top of the recording medium M will not collide with the original S, the recording medium M will be discharged downwards together with the original S.

[0137] According to this embodiment, since the top of the recording medium M will not collide with the original document S, paper jams in the recording medium M can be reduced, and the ejection of the original document S and the ejection of the recording medium M can be performed simultaneously, thereby improving the throughput of the recording process.

[0138] 5. Other implementation methods

[0139] When the original document S is stopped at the position where it obstructs the top of the recording medium M along the second forward path MD2, the control unit 100 can, as a predetermined action to release the stopped state, also notify the operation unit 15 that the original document S should be ejected from the reading mechanism 11. As a notification method, for example, a warning display can be shown on the display panel of the operation unit 15, or a warning sound can be generated from the operation unit 15. If this method is used, the original document S in the stopped state can be ejected by notification implemented by the operation unit 15 before the top of the recording medium M reaches the intersection position CP, thereby allowing the recording medium M to be ejected smoothly without obstructing the second forward path MD2.

[0140] Furthermore, for example, when the original document S becomes blocked and stops on the transport path FR, the control unit 100 can maintain the state of stopping the discharge of the original document S from the original document discharge outlet 64, and notify the operator 15 of the blockage. If this method is used, damage to the original document S can be prevented.

[0141] Furthermore, for example, if the original document S stops reading midway along the transport path FR due to poor transport conditions, the control unit 100 can restart the reading of the original document S before the top of the recording medium M discharged from the media outlet 58 reaches the cross position CP. If this method is used, if reading restarts without stopping the original document S, the risk of paper jams can be reduced even if the recording medium M collides with the original document S. Alternatively, in this case, before restarting the reading of the stopped original document S, the control unit 100 can restart the reading of the original document S after transporting the original document S in a predetermined amount in the opposite direction to the first discharge direction D1. This allows for reliable reading of the original document S.
