Description

TECHNICAL FIELD

[0001] The present application relates to a recording apparatus that performs recording on a medium and a reading method of a recorded image in the recording apparatus. BACKGROUND

[0002] The printer described in Patent Literature 1 is provided with an image sensor in an ejection path in which a paper on which recording has been performed is ejected, and confirms the presence or absence of an ink ejection failure by the image sensor.

[0032] Hereinafter, the present application will be described.

[0033] The recording apparatus according to the first aspect is characterized by including: a recording section that performs recording by ejecting a liquid onto a medium; a medium conveying path that conveys the medium; a switching section that switches a feeding direction of the medium on which recording has been performed by the recording section, the medium conveying path having: a recording path that passes through the recording section; a feeding path that is the medium conveying path connected to the recording path and feeds the medium to the recording path; a discharge path that is the medium conveying path connected to the recording path and discharges the medium on which recording has been performed by the recording section; and a reading path that is the medium conveying path passing through a reading section that reads an image and is provided independently of the recording path, the feeding path, and the discharge path, the reading path being fed with the medium on which a recording image for checking an ejection state of the liquid ejected by the recording section is recorded, the switching section switching between a first state in which the feeding direction is set to the reading path and a second state in which the feeding direction is set to a path other than the reading path.

[0034] According to the present aspect, since the reading path passing through the reading section that reads an image is the medium conveying path provided independently of the recording path, the feeding path, and the discharge path, the medium on which normal recording has been performed passes through the discharge path, and the medium on which a recording image for checking an ejection state of the liquid ejected by the recording section is recorded passes through the reading path. Also, the medium before recording passes through the feeding path. Thus, the reading section is less likely to be contaminated, and it is possible to appropriately check the ejection state of the liquid ejected by the recording section.

[0035] The second method is characterized in that, in the first method, a pair of transport rollers is provided on the recording path, the pair of transport rollers transporting the medium to a position opposite to the recording unit by rotating forward when recording is performed by the recording unit, the reading path is set at a position where the medium is fed in by reversing the transport rollers, the recorded image of the medium fed into the reading path by reversing the transport rollers is located at a position far from the transport rollers relative to the reading unit, and is read by the reading unit when the transport rollers rotate forward.

[0036] According to this method, since the reading unit and the recorded image are located upstream of the conveying roller pair when the conveying roller pair rotates forward, and the reading of the recorded image is performed when the conveying roller pair rotates forward, the medium is stretched and conveyed at the position of the reading unit. As a result, the conveying accuracy of the medium when reading the recorded image can be improved, and the recorded image can be read appropriately.

[0037] The third method is characterized in that, in the second method, when the conveying roller pair is rotating in the forward direction and when the medium is read by the reading unit, the roller pair that clamps the medium is only the conveying roller pair.

[0038] According to this method, since the only roller pair that holds the medium is the conveying roller pair when the conveying roller pair rotates forward and when the medium is read by the reading unit, the conveying load applied to the conveying roller pair when reading the recorded image is reduced, the conveying accuracy of the medium when reading the recorded image is improved, and the recorded image can be read appropriately.

[0039] The fourth method is characterized in that, in the second method, the upstream portion of the reading path of the conveying roller pair when it rotates forward is straight compared to the reading section.

[0040] According to this method, since the upstream portion of the path of the conveying roller pair in the reading path is straight compared to the reading section when the conveying roller pair rotates forward, the conveying load applied to the conveying roller pair when reading the recorded image is reduced, thereby improving the conveying accuracy of the medium when reading the recorded image, and thus enabling the recorded image to be read appropriately.

[0041] The fifth method is characterized in that, in the second method, a pressing part is provided at a position opposite to the reading part, the pressing part pressing the medium toward the reading part.

[0042] According to the present aspect, since the pressing portion that presses the medium toward the reading portion is provided at a position opposite to the reading portion, the medium can be closely attached to the reading portion, and thus good reading accuracy can be obtained.

[0043] The sixth aspect is characterized in that, in the fifth aspect, the feeding path is the medium conveying path through which the medium fed from the medium housing portion located below with respect to the recording path, and the medium fed from the medium housing portion is turned by a turning roller and guided to the recording path, the turning roller and the pressing portion are integrated and configured to be detachable with respect to a device main body provided with the recording portion.

[0044] According to the present aspect, since the turning roller and the pressing portion are integrated and configured to be detachable, repair work in a case where a jam of the medium occurs inside the device main body can be easily performed, and since the reading portion is separated from the pressing portion, cleaning of the reading portion and the pressing portion can also be easily performed.

[0045] The seventh aspect is characterized in that, in the fifth aspect, a reading unit provided with the reading portion has a guide portion that guides the medium between the reading portion and the pressing portion when the pair of conveying rollers are reversed.

[0046] According to the present aspect, since the reading unit provided with the reading portion has the guide portion that guides the medium between the reading portion and the pressing portion when the pair of conveying rollers are reversed, the medium can be guided between the reading portion and the pressing portion without providing a dedicated guide member, and thus an increase in cost can be suppressed.

[0047] The eighth aspect is characterized in that, in the sixth aspect, the recording path extends along a device depth direction, an uppermost portion of the turning roller is located upward with respect to the recording path, the feeding path is formed in a downward inclined shape from the uppermost portion of the turning roller toward a downstream, the reading path is located upward with respect to the feeding path and has a path portion that extends along a path portion of the downward inclined shape in the feeding path, the recording portion is provided on a carriage that is movable in a width direction intersecting a medium conveying direction in the reading path, the reading portion is located between the carriage and the turning roller in the device depth direction, and a portion of the carriage and a portion of the turning roller are located within a height range of the reading portion in a device height direction.

[0048] According to the present aspect, since the reading section is configured to effectively use the space between the carriage and the turning roller by being located between the carriage and the turning roller in the longitudinal direction of the device and by a part of the carriage and a part of the turning roller being located within the height range of the reading section in the vertical direction of the device, the device can be miniaturized.

[0049] The ninth aspect is characterized in that, in the first aspect, a pair of conveying rollers is provided on the recording path, the pair of conveying rollers conveys the medium to a position opposite the recording section by being rotated in the forward direction when recording is performed by the recording section, and the switching section switches between the first state and the second state by obtaining power from a driving roller that is a roller constituting the pair of conveying rollers.

[0050] According to the present aspect, since the switching section is configured to switch between the first state and the second state by obtaining power from a driving roller that is a roller constituting the pair of conveying rollers, a dedicated power source for driving the switching section is not required, and cost increase, weight increase, and size increase of the device can be suppressed.

[0051] The tenth aspect is characterized in that, in the ninth aspect, a power transmission section is provided, the power transmission section is capable of switching between a power transmission state in which power is transmitted from the driving roller to the switching section and a non-power transmission state in which power is not transmitted from the driving roller to the switching section, the recording section is provided on a carriage, the carriage is capable of moving in a width direction that intersects the medium conveying direction in the reading path, and the power transmission section includes an abutting member that is a member capable of moving in the moving direction of the carriage and forms the non-power transmission state by being located in a first position and forms the power transmission state by being located in a second position, and a pressing member that presses the abutting member from the second position to the first position, the abutting member moves from the first position to the second position by being pressed by the carriage.

[0052] According to the present aspect, since the power transmission section is configured to switch the power transmission state by the movement of the abutting member and the abutting member moves from the first position to the second position by being pressed by the carriage, a dedicated power source for moving the abutting member is not required, and cost increase, weight increase, and size increase of the device can be suppressed.

[0053] The eleventh aspect is characterized in that, in the tenth aspect, the first position and the second position are located within the moving region of the carriage when the recording section performs recording on the medium.

[0054] According to the present embodiment, since the first position and the second position are located in the movement region of the carriage when the recording section performs recording on the medium, the expansion of the movement region of the carriage accompanying the setting of the first position and the second position can be suppressed, and thus the device can be prevented from becoming large.

[0055] The twelfth aspect is characterized in that, in the eleventh aspect, an initial position is set in the movement region of the carriage at a position where the recording section is capped and which is different from the first position and the second position, and the carriage moves to the initial position before starting to read the recorded image after the medium on which the recorded image is recorded is fed into the reading path.

[0056] According to the present embodiment, since an initial position is set in the movement region of the carriage at a position where the recording section is capped and which is different from the first position and the second position, and the carriage moves to the initial position before starting to read the recorded image after the medium on which the recorded image is recorded is fed into the reading path, the drying of the recording section is suppressed, and thus the appropriate recording quality can be maintained.

[0057] The thirteenth aspect is characterized in that, in the twelfth aspect, the abutting member obtains power from the drive roller, retreats from the position where the abutting member can abut against the carriage by the forward rotation of the drive roller, and enters the position where the abutting member can abut against the carriage by the reverse rotation of the drive roller.

[0058] According to the present embodiment, since the abutting member obtains power from the drive roller, retreats from the position where the abutting member can abut against the carriage, or enters the position where the abutting member can abut against the carriage, a dedicated power source for driving the abutting member is not needed, and thus the cost increase, the weight increase, and the large size of the device can be suppressed.

[0059] The fourteenth aspect is a reading method of a recording image in a recording apparatus, the recording apparatus including: a recording path that is a medium conveying path that conveys a medium and that passes through a recording section that records by ejecting liquid onto the medium; a feeding path that is the medium conveying path that is connected to the recording path and that feeds the medium to the recording path; a discharge path that is the medium conveying path that is connected to the recording path and that discharges the medium on which recording has been performed by the recording section; a reading path that is the medium conveying path that passes through a reading section that reads an image and that is provided independently of the recording path, the feeding path, and the discharge path and that is fed with a medium on which a recording image for checking an ejection state of liquid ejected by the recording section is recorded; and a switching section that switches a feeding direction of the medium on which recording has been performed by the recording section and that switches between a first state in which the feeding direction is set to the reading path and a second state in which the feeding direction is set to a path other than the reading path, the reading method including: recording the recording image by the recording section; conveying the medium with the reading section positioned between the recording section and the recording image; and reading the recording image by the reading section while conveying the medium in a manner in which the recording image faces the recording section.

[0060] According to the present aspect, since the reading path that passes through the reading section that reads an image is a medium conveying path that is provided independently of the recording path, the feeding path, and the discharge path, a medium on which normal recording has been performed passes through the discharge path, and a medium on which a recording image for checking an ejection state of liquid ejected by the recording section is recorded passes through the reading path. Also, a medium before recording passes through the feeding path. Thus, the reading section is less likely to be contaminated, and the ejection state of liquid ejected by the recording section can be properly checked.

[0061] Hereinafter, the present application will be described in detail.

[0062] Hereinafter, an inkjet printer 1 will be described as one example of a recording apparatus. Hereinafter, the inkjet printer 1 will be simply referred to as a printer 1.

[0063] In addition, in the X-Y-Z coordinate system shown in each drawing, the X-axis direction is the apparatus width direction and becomes the width direction of a medium on which recording is performed. When viewed from an operator of the printer 1, the +X direction becomes the left side, and the -X direction becomes the right side.

[0064] The Y-axis direction is the depth direction of the apparatus, and is the direction along the medium conveying direction at the time of recording. The +Y direction is the direction from the back surface of the apparatus toward the front surface, and the -Y direction is the direction from the front surface of the apparatus toward the back surface. In the present embodiment, the side surface of the apparatus that is provided with the operation section 3, that is, the side surface in the +Y direction becomes the front surface of the apparatus, and the side surface in the -Y direction becomes the back surface of the apparatus.

[0065] The Z-axis direction is the direction along the vertical direction, and is the height direction of the apparatus. The +Z direction is the upward direction in the vertical direction, and the -Z direction is the downward direction in the vertical direction.

[0066] Further, in some of the drawings, the A-axis direction and the B-axis direction are shown. The A-axis direction is the direction in which the path portion of the reading conveying path T5 opposite the reading unit 50 extends, and the +A direction is the direction including a +Y direction component and a -Z direction component. The B-axis direction is the direction orthogonal to the A-axis direction, and the +B direction is the direction including a +Y direction component and a +Z direction component.

[0067] Further, hereinafter, the direction in which the medium is conveyed is sometimes referred to as "downstream", and the opposite direction thereof is sometimes referred to as "upstream".

[0068] In Fig. 1(A), the printer 1 is provided with an operation section 3 for performing various operation settings on the front surface of an apparatus main body 2 that is a device main body for performing inkjet recording on a medium represented by a recording sheet. Further, on the front surface of the apparatus main body 2, an ink remaining amount display section 4 is provided.

[0069] The symbol 5 is a front surface cover that is openable and closable, and is rotatably provided with a rotation axis 5a (refer to Fig. 2) as a center with respect to a cassette 8 described later. By being opened, the symbol 5 constitutes a part of a paper discharge tray. Figure 2

[0070] In Fig. 1(B), on the back surface of the apparatus main body 2, a turnover unit 6 (also refer to Fig. 2) is provided in a detachable manner with respect to the apparatus main body 2. The turnover unit 6 integrally has a turnover roller 15 and a pressing section 72 (refer to Fig. 2) described later. Figure 9 Figure 2

[0071] Next, the medium conveying path in the printer 1 is described with reference to Fig. 3. In Fig. 3, the apparatus main body 2 is shown as a transparent body. Figure 2 Figure 2 ​​​​In the diagram, the media transport path is indicated by a dashed line. As the media transport path for transporting the media, the printer 1 includes a feed path T1 for feeding media from the media cartridge 8 at the bottom of the device, a recording path T2 passing through a position opposite the recording head 34, an discharge path T3 for discharging the recorded media, a reversal path T4 for feeding the recorded media into the reversal roller 15, and a reading path T5 for feeding media with a recorded nozzle check pattern. The nozzle check pattern is an example of a recorded image used to check the ejection state of the ink ejected from the recording head 34.

[0072] In this embodiment, the feeding path T1 is the path from the pick-up roller 10 through the flip roller 15 to the conveying roller pair 20.

[0073] The recording path T2 is the path from the conveyor roller pair 20 to the discharge roller pair 26. In this embodiment, the recording path T2 extends along the Y-axis direction, that is, along the depth direction of the device, i.e., along the horizontal direction.

[0074] The discharge path T3 is the downstream (+Y direction) path starting from the discharge roller pair 26.

[0075] The flipping path T4 is the path from the conveyor roller pair 20 through the flipping roller 15 back to the conveyor roller pair 20.

[0076] The reading path T5 is a path in the -Y direction relative to the conveyor roller pair 20, and it is a path passing between the reading unit 50 and the pressing part 72.

[0077] On the feed path T1, the medium is fed from the medium box 8, which serves as a medium storage unit, by the pickup roller 10 in the -Y direction. The medium box 8 is configured to be detachable from the device body 2. Figure 2 In the text, the symbol P represents the medium stored in the media container 8.

[0078] The pickup roller 10 is supported by a roller support 11 that can rotate about a rotation axis 11a, and moves forward and backward relative to the medium housed in the medium cartridge 8 by rotating the roller support 11. The pickup roller 10 receives a conveyor motor 91 (see reference). Figure 3 Driven by ) Figure 2 Rotate counterclockwise.

[0079] The medium fed from the pickup roller 10 in the -Y direction is bent and flipped by the flipping roller 15 and conveyed toward the conveying roller pair 20.

[0080] The tilting roller 15 receives the conveyor motor 91 (see reference). Figure 3 Driven by ) Figure 2The roller rotates counterclockwise. A first driven roller 16, a second driven roller 17, a third driven roller 18, and a fourth driven roller 19 are arranged around the tilting roller 15. The medium delivered from the medium box 8 by the pick-up roller 10 is held by the tilting roller 15 and the first driven roller 16, the second driven roller 17, and the third driven roller 18 and conveyed downstream.

[0081] The conveyor roller pair 20, positioned on the recording path T2, is configured with a conveyor drive roller 21 and a conveyor driven roller 22. The conveyor drive roller 21 receives a conveyor motor 91 (see reference). Figure 3 The conveyor drive roller 21 rotates forward and reverse due to the power of the conveyor drive roller 21. In this specification, the forward rotation of the conveyor drive roller 21 means that the conveyor drive roller 21 rotates in the opposite direction. Figure 2 The rotation direction is counterclockwise, and the medium is fed out in the +Y direction. This is sometimes referred to as the forward rotation of the conveyor roller pair 20. Additionally, the conveyor motor 91 in this case (see reference...) Figure 3 The rotation of the conveyor motor 91 is called the forward rotation.

[0082] Furthermore, in this specification, the reversal of the conveyor drive roller 21 refers to the conveyor drive roller 21 moving in the opposite direction. Figure 2 The rotation direction is clockwise, and the medium is fed out in the -Y direction. This is sometimes referred to as the reverse rotation of the conveyor roller pair 20. Furthermore, the conveyor motor 91 in this case (see reference...) Figure 3 The rotation of the conveyor motor 91 is called the reverse rotation.

[0083] The driven conveyor roller 22 rotates drivenly while holding the medium between itself and the drive conveyor roller 21. The driven conveyor roller 22 is supported on a roller support member 23. The roller support member 23 is configured to rotate about a rotation axis (not shown), and the driven conveyor roller 22 moves forward and backward relative to the drive conveyor roller 21 by the rotation of the roller support member 23. Reference numeral 24 represents an example of a tension spring that presses against the roller support member 23 to press the driven conveyor roller 22 against the drive conveyor roller 21.

[0084] In the recording path T2, downstream of the transport roller pair 20, a recording head 34 and a support member 40, as an example of a recording unit, are arranged opposite each other. In this embodiment, the recording head 34 is configured as an inkjet recording head that ejects ink. For the recording head 34, ink is supplied from the ink tank 35 via the ink tube 36.

[0085] The support member 40 defines the gap between the recording head 34 and the medium by supporting the medium.

[0086] The carriage 33, equipped with the recording head 34, is configured to drive the carriage motor 92 (see reference). Figure 3It can move in the X-axis direction, i.e., the width of the medium, as a power source.

[0087] A main frame 32 is provided in the -Y direction relative to the carriage 33. The carriage 33 is supported by the main frame 32 and moves in the X-axis direction.

[0088] A discharge roller pair 26 is provided downstream of the recording head 34 and the support member 40 on the recording path T2. The discharge drive roller 27 is connected to the receiving conveyor motor 91 (see reference). Figure 3 The discharge drive roller 27 rotates forward and reverse due to the power of the discharge drive roller 27. In this specification, the forward rotation of the discharge drive roller 27 refers to the rotation of the discharge drive roller 27 towards... Figure 2 The direction of rotation is counterclockwise, which feeds the medium out in the +Y direction. Alternatively, it is sometimes referred to as the forward rotation of the discharge roller pair 26.

[0089] Furthermore, in this specification, the reversal of the discharge drive roller 27 refers to the discharge drive roller 27 moving in the opposite direction. Figure 2 The rotation direction is clockwise, which feeds the medium out in the -Y direction. Alternatively, it is sometimes referred to as the reverse rotation of the discharge roller pair 26.

[0090] The driven discharge roller 28 is configured to move forward and backward relative to the drive discharge roller 27, and is pressed against the drive discharge roller 27 by a spring (not shown), while holding the medium between itself and the drive discharge roller 27 and rotating it passively. The medium that has been recorded is discharged in the +Y direction through the discharge roller pair 26.

[0091] In addition, a limiting roller 29 is provided near the upstream of the discharge roller pair 26, and a limiting roller 30 is provided near the downstream of the discharge roller pair 26. The discharged medium is restricted from floating upward by the limiting rollers 29 and 30.

[0092] In addition, Figure 3 In this system, the control unit 90 can determine the rotation amount of the pickup roller 10, the flip roller 15, the conveying drive roller 21, and the discharge drive roller 27 based on the detection information from the rotation detection unit 93. The rotation detection unit 93 detects the rotation amount of the conveying motor 91 and can be configured, for example, by a rotary encoder.

[0093] Furthermore, the control unit 90 can determine the position of the carriage 33 in the X-axis direction based on the detection information from the carriage position detection unit 94. The carriage position detection unit 94 can be, for example, a linear encoder.

[0094] Furthermore, the control unit 90 can determine, based on the detection information from the media detection unit 95, whether the top of the media has reached the vicinity of the upstream of the conveying roller pair 20 (see reference). Figure 10The medium detection section 95 can be configured by an optical sensor or a contact sensor disposed in the vicinity of the -Y direction with respect to the pair of conveyance rollers 20.

[0095] Returning to Figure 2 When recording is performed on a second face of the medium opposite the first face, the control section 90 (see Fig. 1) that controls the conveyance motor 91 causes the conveyance motor 91 to reverse, thereby feeding the medium into the reversal path T4. In this case, the medium is pinched by the reversal roller 15 and the fourth driven roller 19, and then pinched by the reversal roller 15, the first driven roller 16, the second driven roller 17, and the third driven roller 18 and conveyed downstream. The medium conveyed in the reversal path T4 is reversed by the reversal roller 15 so that the second face opposes the recording head 34, and is conveyed to the recording path T2. Figure 3

[0096] In addition, although in the present embodiment the medium on which recording has been performed is reversed in the -Y direction and returned to the feed path Tl side, and then enters the reversal path T4, the reversal path T4 is not limited to this position, and can be provided at a position branching from the discharge path T3.

[0097] However, by providing the structure in which the reversal path T4 uses a portion of the feed path Tl as in the present embodiment, compared to a structure in which the reversal path T4 is formed exclusively, it is possible to suppress the size of the device.

[0098] Between the pair of conveyance rollers 20 and the reversal roller 15, a switching baffle 42 is provided as one example of a switching section. In the case of feeding the medium into the reversal path T4, and in the case of connecting the feed path Tl and the recording path T2, the switching baffle 42 is set to the second state indicated by the solid line. Figure 2

[0099] In the case of feeding the medium on which recording has been performed, and more specifically the medium on which the nozzle check pattern described later is recorded, into the reading path T5, the switching baffle 42 is set to the first state indicated by the two-dot chain line and the symbol 42-1 by control of the control section 90. Figure 2

[0100] Thus, the switching baffle 42 is a section that switches the feeding direction of the medium on which recording has been performed, and switches between the first state in which the feeding direction is set to the reading path T5, and the second state in which the feeding direction is set to a path other than the reading path T5 (in the present embodiment, the reversal path T4).

[0101] ​​​On the read path T5, a read unit 50 as one example of a read section is provided. The read unit 50 has a sensor module 51 as one example of a read sensor, and the sensor module 51 is a CISM (Contact Image Senser Module) as one example. The read unit 50 reads the face of the medium conveyed on the read path T5. On a position opposite to the read unit 50, a press section 72 that presses the medium toward the read unit 50 is provided.

[0102] The press section 72 is pressed toward the read unit 50 by a press spring 73 as one example of a press member. Thereby, the medium can be closely attached to the read unit 50, and good reading accuracy can be obtained.

[0103] The lower side of the read path T5 is formed by an inclined guide member 45, and the press section 72 and the press spring 73 are provided on the inclined guide member 45. The inclined guide member 45 constitutes the turnover unit 6 as shown in Figure 9 The read path T5 is formed on the upper side of the inclined guide member 45, and the path portion from the uppermost portion of the turnover roller 15 toward the downstream in the feed path T1 is formed in a descending inclined shape along the inclined guide member 45.

[0104] The read unit 50 has a housing structure 50a as shown in Figure 21 The sensor module 51 and the housing structure 50a constitute the read unit 50.

[0105] In the second housing member 55 that constitutes the housing structure 50a, a guide portion 55a that guides the medium between the read unit 50 and the press section 72 when the medium is fed into the read path T5 by reversing the convey roller pair 20 is formed. Thereby, the medium can be guided between the read unit 50 and the press section 72 without providing a dedicated guide member, and cost increase can be suppressed.

[0106] Here, reference is made to Figure 14The configuration of the reading unit 50 is described in detail. The uppermost part 15a of the flip roller 15 is located above the recording path T2. The feed path T1 slopes downwards from the uppermost part 15a of the flip roller 15 towards the downstream (+Y direction). The reading path T5 is located above the feed path T1 and has a path portion extending along the downward sloped path portion of the feed path T1. In the Y-axis direction, i.e., the depth direction of the device, the reading unit 50 is located in the region Y1 between the carriage 33 and the flip roller 15. Moreover, in the Z-axis direction, i.e., the height direction of the device, a portion of the carriage 33 and a portion of the flip roller 15 are located within the height range of the reading unit 50. The range indicated by the symbol Z1 is the height range of the reading unit 50, the range indicated by the symbol Z2 is the height range of the flip roller 15, and the range indicated by the symbol Z3 is the height range of the carriage 33.

[0107] As shown in the figure, a portion of the height range Z3 of the carriage 33 and a portion of the height range Z2 of the flip roller 15 are located within the height range Z1 of the reading unit 50.

[0108] With this structure, the reading unit 50 is configured in a way that makes efficient use of the space between the carriage 33 and the flip roller 15, thereby enabling the miniaturization of the device.

[0109] Alternatively, the reading unit 50 can be configured such that the height range Z1 of the reading unit 50 is within the height range Z2 of the flip roller 15.

[0110] Next, the structure for implementing the state switching of the switching baffle 42 will be explained.

[0111] The carriage 33 sets its initial position at the -X direction end within its movable range. Figure 5 , Figure 6 In the middle, positions X0, X1, X2, and Xc are the side walls 33a in the +X direction of the carriage 33 ( Figure 8 (Refer to) Possible positions. For convenience, positions X0, X1, X2, and Xc will be described below as the positions of carriage 33.

[0112] Position X0 is the initial position of the carriage 33. Furthermore, position X1 is the position of the carriage 33 when it moves to the -X direction at the farthest point of the recordable range A1, and position X2 is the position of the carriage 33 when it moves to the +X direction at the farthest point of the recordable range A1. Also, position Xc is the center position of the recordable range A1.

[0113] The initial position X0 of the carriage 33 is set in the -X direction, which is one side, relative to the center position Xc.

[0114] Further, in the +X direction as the other side with respect to the center position Xc, an abutting lever 110a as one example of an abutting member is provided. The shape of the abutting lever 110a is detailed in Figure 4 FIG. 7. The abutting lever 110a constitutes a power transmission section 100, which is disposed in the +X direction with respect to the center position Xc.

[0115] The power transmission section 100 is configured to be switchable between a power transmission state in which power of the conveyance drive roller 21 is transmitted to the switching baffle 42, and a non-power transmission state in which power of the conveyance drive roller 21 is not transmitted to the switching baffle 42. This switching is performed by the carriage 33.

[0116] As shown in Figure 4 , the power transmission section 100 has gears 101, 102, 103, 104, 105, 106, 107, 108, a rotating member 110, the abutting lever 110a, and a press spring 111 as one example of a press member (see FIG. 7).

[0117] When the power transmission section 100 becomes the power transmission state, power is transmitted from the gear 101 provided on the conveyance drive roller 21 to the gears 102, 103, 104, 105, 106, 107, 108 in this order. As shown in Figure 5 and Figure 6 , the gear 108 is a gear provided on a rotation shaft 42a of the switching baffle 42 in the +X direction.

[0118] In addition, the gears 106, 107 are secondary gears. Further, the gear 102 and the gear 103 are disposed coaxially and rotate integrally. Further, the gear 104 and the gear 105 are also disposed to rotate coaxially. Although detailed description is omitted, the gear 104 and the gear 105 are configured to transmit torque via friction, whereby the gears 104, 103, 102 can continue to rotate in a state in which the gears 108, 107, 106, 105 are stopped.

[0119] The rotation shaft 42a of the switching baffle 42 in the +X direction is rotatably supported by the left frame 80 (see Figure 15 , Figure 16 ), and the rotation shaft 42a in the -X direction is rotatably supported by the right frame 81 (see Figure 15 , Figure 16 ). The rotation shaft center of the switching baffle 42 is parallel to the X-axis direction, that is, intersects the medium conveyance direction.

[0120] The rotation limit of the switching baffle 42 when the conveyance motor 91 is reversed and the rotation limit of the switching baffle 42 when the conveyance motor 91 is rotated forward are defined by the switching baffle 42 abutting against a rotation limiting portion not shown.

[0121] In addition, the switching baffle 42 is pressed in the downward direction, i.e., the direction in which the second state is taken, by a tension spring 43 (refer to Figure 10 、 Figure 11 ).

[0122] The gear 103 is arranged so as to be displaceable in the X-axis direction and is switched between a state (refer to Figure 6 ) in which the gear 103 is engaged with the gear 104 and a state (refer to Figure 5 ) in which the gear 103 is not engaged with the gear 104 by being displaced in the X-axis direction. The power transmission state of the power transmission portion 100 is formed by the gear 103 being engaged with the gear 104, and the non-power transmission state of the power transmission portion 100 is formed by the gear 103 not being engaged with the gear 104.

[0123] In the power transmission state of the power transmission portion 100 and the second state in which the switching baffle 42 sets the medium feeding direction to the inversion path T4, when the conveyance drive roller 21 is reversed, the switching baffle 42 is switched from the second state to the first state, i.e., the state in which the medium feeding direction is set to the reading path T5.

[0124] Further, in the power transmission state of the power transmission portion 100 and the first state in which the switching baffle 42 sets the medium feeding direction to the reading path T5, when the power transmission portion 100 is switched to the non-power transmission state, the switching baffle 42 is switched from the first state to the second state, i.e., the state in which the medium feeding direction is set to the inversion path T4, by the weight and the elastic force of the tension spring 43.

[0125] In addition, it is also possible to switch the switching baffle 42 from the first state to the second state by rotating the conveyance drive roller 21 forward. Further, it is also possible to switch the switching baffle 42 from the first state to the second state by the weight alone.

[0126] As shown in FIG. 7, the gear 103 is pressed in the +X direction by a pressing spring 111. Further, the pressing spring 111 presses the rotation member 110 in the +X direction via the gear 103.

[0127] An abutment rod 110a is integrally formed on the rotating member 110. The rotating member 110 can rotate by friction with the gear 102. When the conveying drive roller 21 rotates forward in the power transmission state of the power transmission unit 100, it abuts against the rod abutment portion 112 as shown in FIG. 7(A) and maintains this state. In this state, the abutment rod 110a is located in the movement area of ​​the carriage 33 and cannot retract from the engagement portion 33b provided on the back of the carriage 33 (see reference). Figure 8 The position where they meet.

[0128] An opening 32b is formed on the lower frame portion 32a of the main frame 32. Furthermore, when the conveyor drive roller 21 reverses in the power transmission state of the power transmission unit 100, as shown in FIG7(B), the abutment rod 110a enters the opening 32b and abuts against the abutment surface 32c of the opening 32b. In this state, the abutment rod 110a is located in the moving area of ​​the carriage 33 and can engage with the engaging portion 33b (see reference 32b) provided on the back of the carriage 33. Figure 8 The position of contact. The position of the contact rod 110a in this state along the X-axis is set as the first position X3 (refer to...). Figure 5 When the abutment rod 110a is in the first position X3, gear 103 and gear 104 are not engaged.

[0129] When the carriage 33 moves from the +X direction to the -X direction in this state, the engaging portion 33b provided on the back of the carriage 33 presses the abutment rod 110a in the -X direction. As a result, the rotating member 110, integrally formed with the abutment rod 110a, moves the gear 103 in the -X direction, resulting in gear 103 meshing with gear 104. That is, the power transmission state of the power transmission unit 100 is achieved. The position of the abutment rod 110a in the X-axis direction in this state is designated as the second position X4 (refer to...). Figure 6 ).

[0130] Next, the feeding of the medium into the read path T5 will be explained. Furthermore, the various controls described below are implemented via data stored in the control unit 90 (see reference 90). Figure 3 Control is achieved by using the program (not shown) in the non-volatile memory (not shown) of the device.

[0131] The control unit 90 executes a nozzle check mode at a predetermined time. The nozzle check mode is characterized by using a nozzle check pattern Cp (refer to...) to check the ink ejection status of the recording head 34. Figure 13) recorded on the medium Pt, and the medium Pt on which the nozzle check pattern Cp is recorded is fed into the reading path T5 to be read by the reading unit 50, and based on the reading result, it is judged whether or not a clogging of the ink ejection nozzle (not shown) has occurred. The control section 90 displays an error on the display section (not shown) of the operation section 3 (refer to FIG. 1(A)) or the display section (not shown) of the computer connected to the printer 1 in the case where a clogging of the ink ejection nozzle has occurred, and performs the automatic cleaning of the recording head 34 in the case where the automatic cleaning is enabled. This automatic cleaning is an operation of covering the recording head 34 with a cover (not shown) and generating a negative pressure in the cover, and sucking the ink from the ink ejection nozzle.

[0132] In the present embodiment, the nozzle check mode can be executed at an arbitrary timing by the user via the operation section 3 (refer to FIG. 1(A)).

[0133] Further, in the present embodiment, the nozzle check mode can be selected as to whether or not it is automatically executed via the operation section 3 (refer to FIG. 1(A)). Further, in the present embodiment, the first automatic mode and the second automatic mode are included in the automatic execution of the nozzle check mode.

[0134] In the case where the first automatic mode is selected, when the pre-recording check is enabled, the control section 90 executes the nozzle check mode before the start of recording upon acceptance of a recording execution instruction. Further, in the case where the first automatic mode is selected, even in the middle of the execution of the recording job, when the number of sheets of recording after the execution of the last nozzle check mode reaches the number of sheets of recording which is set in advance, the control section 90 interrupts the recording job and executes the nozzle check mode.

[0135] In the case where the second automatic mode is selected, the control section 90 sets an execution flag of the nozzle check mode to on when the number of sheets of recording after the execution of the last nozzle check mode reaches the number of sheets of recording which is set in advance. Then, in the case where the execution flag is on before the start of the next recording, the nozzle check mode is executed. In addition, in the second automatic mode, even when the number of sheets of recording after the execution of the last nozzle check mode reaches the number of sheets of recording which is set in advance in the middle of the execution of the recording job, the recording job is not interrupted to execute the nozzle check mode.

[0136] Next, the control of the control section 90 at the time of execution of the nozzle check mode will be described in more detail with reference to Figure 12

[0137] The control section 90 judges whether or not it is the execution timing of the nozzle check mode, and when it is judged to be the execution timing of the nozzle check mode, it executes the recording of the nozzle check pattern Cp (step S101). In addition, after the recording of the nozzle check pattern Cp is completed, the medium trailing end is positioned between the conveyance roller pair 20 and the medium detection section 95. ​

[0138] Next, the control section 90 moves the carriage 33 to the end portion in the +X direction (step S102), and next reverses the conveyance motor 91 by a first prescribed amount (step S103). Thereby, as shown by the change from the state of Fig. 7(A) to the state of Fig. 7(B), the abutment lever 110a enters the movement region of the carriage 33. At this time, the abutment lever 110a is positioned at the first position X3 (refer to Fig. 7). In addition, by the execution of step S103, the medium Pt is moved by several amounts in the -Y direction, and thereby, as shown in Fig. 7(B), the rear end Pe of the medium Pt is positioned at the -Y direction with respect to the medium detection section 95. In this state, the switching damper 42 is in the second state. Figure 5 In addition, by the execution of step S103, the medium Pt is moved by several amounts in the -Y direction, and thereby, as shown in Fig. 7(B), the rear end Pe of the medium Pt is positioned at the -Y direction with respect to the medium detection section 95. In this state, the switching damper 42 is in the second state. Figure 10 In addition, by the execution of step S103, the medium Pt is moved by several amounts in the -Y direction, and thereby, as shown in Fig. 7(B), the rear end Pe of the medium Pt is positioned at the -Y direction with respect to the medium detection section 95. In this state, the switching damper 42 is in the second state.

[0139] Next, the control section 90 moves the carriage 33 in the -X direction (step S104), and thereby, the abutment lever 110a moves from the first position X3 to the second position X4 (refer to Fig. 7), and the power transmission section 100 is switched to the power transmission state. Figure 6

[0140] In this state, the control section 90 reverses the conveyance motor 91 by a first prescribed amount, that is, rotates the conveyance roller pair 20 in the positive direction (step S105). Thereby, the medium Pt moved in the -Y direction by the execution of step S103 returns to the original position. By this processing, the rear end of the medium Pt is again disposed between the conveyance roller pair 20 and the medium detection section 95.

[0141] In addition, at this time, the abutment lever 110a desires to retreat from the movement region of the carriage 33 by the rotation of the conveyance motor 91, but in this state, the abutment lever 110a enters the limiting hole 32d formed on the lower frame section 32a (refer to Fig. 7) of the main frame 32 (refer to Fig. 7), and thereby, the state of entering the movement region of the carriage 33 is maintained. That is, the power transmission section 100 is maintained in the power transmission state.

[0142] Next, the control section 90 reverses the conveyance motor 91, that is, reverses the conveyance roller pair 20 (step S106). At the initial stage of this reversal of the conveyance motor 91, as shown in Fig. 7(C), the switching damper 42 is switched to the first state. This reversal of the conveyance motor 91 is continued until the rear end Pe of the medium Pt exceeds the read standby position shown in Fig. 7(D) by several amounts in the +A direction after the rear end Pe of the medium Pt is detected by the medium detection section 95. Figure 11 Figure 11

[0143] Thus, after the rear end Pe of the medium Pt is disposed between the conveyance roller pair 20 and the medium detection section 95, the medium Pt is conveyed in the +A direction, and thereby, the conveyance amount required to accurately convey the medium Pt can be obtained. ​​​

[0144] Next, the control unit 90 moves the carriage 33 to the +X direction end (step S107). As a result, the abutment rod 110a moves from the second position X4 (refer to...). Figure 6 Move to the first position X3 (refer to) Figure 5 When the power transmission unit 100 switches to a non-power transmission state, since the abutment rod 110a has entered the moving area of ​​the carriage 33, the control unit 90 causes the conveyor motor 91 to rotate forward by a first predetermined amount (step S108). As a result, as shown by the change from the state shown in FIG. 7(B) to the state shown in FIG. 7(A), the abutment rod 110a retracts from the moving area of ​​the carriage 33.

[0145] Furthermore, the control unit 90 moves the carriage 33 to an initial position in the -X direction (step S109). As a result, the recording head 34 is covered by a cover (not shown).

[0146] Through the forward rotation of the conveyor motor 91 in step S108, the medium Pt is positioned at... Figure 11 The reading is in the standby position shown. In this state, the nozzle check pattern CP (refer to...) Figure 13 Located in Figure 11 The position Wp shown is closer to the direction marked by the arrow. Position Wp is the furthest position from the conveyor roller pair 20 within the range that can be read by the reading unit 50.

[0147] In other words, the nozzle inspection pattern CP of the medium Pt, which is fed into the reading path T5 by the reversal of the conveyor roller pair 20, is located at a position far from the conveyor roller pair 20 relative to the reading unit 50.

[0148] exist Figure 13 In this context, the distance L1 from the top Pf of the medium Pt to the nozzle inspection pattern CP is longer than the path length between the clamping position held by the conveyor roller pair 20 and the position Wp.

[0149] Next, the control unit 90 reads the nozzle inspection pattern CP through the reading unit 50 while the conveying motor 91, i.e., the conveying roller pair 20, rotates forward (step S110). When the reading of the nozzle inspection pattern CP is finished, the control unit 90 discharges the medium Pt by rotating the conveying motor 91, i.e., the conveying roller pair 20, in the forward direction (step S111).

[0150] As explained above, the printer 1 is provided with the recording path T2, the feeding path T1 connected to the recording path T2, and the discharge path T3 connected to the recording path T2. Further, the reading path T5 which is a transport path of the medium Pt provided independently of the recording path T2, the feeding path T1, and the discharge path T3, and which is a path into which the medium Pt on which the nozzle check pattern CP is recorded is fed, and the switching damper 42 which switches between a first state in which the feeding direction of the medium P on which recording is performed is set to the reading path T5 and a second state in which the feeding direction is set to a path other than the reading path T5 are provided.

[0151] Thus, the medium on which normal recording is performed passes through the discharge path T3, and the medium Pt on which the nozzle check pattern CP is recorded passes through the reading path T5, so the reading unit 50 is less likely to be contaminated, and further, it is possible to appropriately check the ejection state of the ink ejected from the recording head 34.

[0152] Further, in the reading path T5, since the medium is sandwiched by the reading unit 50 and the pressing portion 72, a transport load is generated. Since the medium on which normal recording is performed does not pass through such a reading path T5, there is no case where the reading unit 50 and the pressing portion 72 apply a transport load to the medium on which normal recording is performed.

[0153] In addition, although the recording image for checking the ejection state of the ink ejected from the recording head 34 is the nozzle check pattern CP in the present embodiment, the recording image is not limited thereto, and can be any image as long as the ejection state of the ink, that is, the recording quality can be checked.

[0154] Further, the reading method of the nozzle check pattern CP performed by the control portion 90 of the printer 1 includes a step of recording the nozzle check pattern CP by the recording head 34, a step of transporting the medium Pt in a manner that the nozzle check pattern CP is disposed at a position farther from the recording head 34 with respect to the reading unit 50 (step S104 of the method), a step of reading the nozzle check pattern CP by the reading unit 50 while the medium Pt is transported in a manner that the nozzle check pattern CP faces the recording head 34 (step S105 of the method). Figure 12 Figure 12

[0155] However, it is also possible to read the nozzle check pattern CP in the step of transporting the medium Pt in a manner that the nozzle check pattern CP is disposed at a position farther from the recording head 34 with respect to the reading unit 50.

[0156] ​​Further, the conveying roller pair 20 is provided in the recording path T2, and the conveying roller pair 20 conveys the medium Pt to a position opposite to the recording head 34 by performing forward rotation when recording is performed by the recording head 34, and the reading path T5 is provided at a position where the medium Pt is fed by reverse rotation of the conveying roller pair 20. Also, the nozzle check pattern CP of the medium Pt fed into the reading path T5 by the reverse rotation of the conveying roller pair 20 is positioned at a position farther from the conveying roller pair 20 than the reading unit 50, and is read by the reading unit 50 when the conveying roller pair 20 performs forward rotation.

[0157] Thus, the medium Pt is conveyed while being stretched at the position of the reading unit 50, so that the conveying accuracy of the medium Pt when the nozzle check pattern CP is read can be made good, and further, the nozzle check pattern CP can be properly read.

[0158] Further, the presence or absence of the nozzle check pattern CP can be confirmed by the reading unit 50 when the medium Pt is fed into the reading path T5 by the reverse rotation of the conveying roller pair 20, and in the case where the nozzle check pattern CP cannot be found even if the conveying roller pair 20 is reversed by a predetermined amount, the conveying roller pair 20 is caused to perform forward rotation to discharge the medium Pt as an error, and the nozzle check mode is attempted again.

[0159] Further, when the medium Pt is read by the reading unit 50 when the conveying roller pair 20 performs forward rotation, the roller pair that clamps the medium Pt is only the conveying roller pair 20. Thus, the conveying load applied to the conveying roller pair 20 when the nozzle check pattern CP is read is reduced, the conveying accuracy of the medium Pt when the nozzle check pattern CP is read can be made good, and thus the nozzle check pattern CP can be properly read.

[0160] Further, in the present embodiment, the tip end Pf of the medium Pt is not clamped by the discharging roller pair 26 until reading of the nozzle check pattern CP is completed.

[0161] However, when the medium Pt is read by the reading unit 50 when the conveying roller pair 20 performs forward rotation, the roller pair that clamps the medium Pt can be other than the conveying roller pair 20.

[0162] Further, in the present embodiment, the tip end Pf of the medium Pt does not enter below the recording head 34 when reading of the nozzle check pattern CP is started. However, by causing the tip end Pf of the medium Pt to enter below the recording head 34 when reading of the nozzle check pattern CP is started, disturbance of the conveying accuracy caused by the tip end Pf being caught by the recording head 34 can be suppressed, and thus the nozzle check pattern CP can be properly read.

[0163] Further, the path portion of the reading path T5 upstream of the reading unit 50 when the conveying roller pair 20 performs forward rotation is as shown in Fig. 6.Figure 11 As shown, the posture of the medium Pt upstream of the reading unit 50 when the pair of conveying rollers 20 is positively rotated becomes linear. In other words, the posture of the medium Pt upstream of the reading unit 50 when the pair of conveying rollers 20 is positively rotated becomes linear. Thereby, the conveying load applied to the pair of conveying rollers 20 at the time of reading the nozzle check pattern CP is reduced, the conveying accuracy of the medium Pt at the time of reading the nozzle check pattern CP is made good, and thus the nozzle check pattern CP can be properly read.

[0164] Further, the turning roller 15 and the pressing portion 72 constitute the turning unit 6, and the turning unit 6 is detachable with respect to the device main body 2 provided with the recording head 34. That is, the turning roller 15 and the pressing portion 72 are integrated and are detachable with respect to the device main body 2. The pressing portion 72 is exposed to the outside of the turning unit 6 when the turning unit 6 is detached as shown. Figure 9 The pressing portion 72 is exposed to the outside of the turning unit 6 when the turning unit 6 is detached as shown. Thereby, it is easy to perform the repair work in the case where the medium jam has occurred in the inside of the device main body 2, and since the reading unit 50 is separated from the pressing portion 72, it is also easy to perform the cleaning of the reading unit 50 and the pressing portion 72.

[0165] However, the pressing portion 72 can not be provided on the turning unit 6, but can be fixedly provided with respect to the device main body 2.

[0166] Further, the switching baffle 42 is switched between the first state and the second state by being powered from the conveying drive roller 21 which is a roller constituting the pair of conveying rollers 20. Thereby, it is not necessary to provide a dedicated power source for driving the switching baffle 42, and it is possible to suppress the increase in cost, the increase in weight of the device, and the increase in size.

[0167] However, the switching baffle 42 can be switched in state by other power, and can be configured to be manually performed by the user.

[0168] Further, the printer 1 is provided with a power transmission portion 100 capable of switching between a power transmission state in which power is transmitted from the conveying drive roller 21 to the switching baffle 42 and a non-power transmission state in which power is not transmitted from the conveying drive roller 21 to the switching baffle 42. The power transmission portion 100 is a member capable of moving in the moving direction of the carriage 33, and is provided with an abutting lever 110a which forms the non-power transmission state by being positioned at a first position X3 and forms the power transmission state by being positioned at a second position X4, and a pressing spring 111 which presses the abutting lever 110a from the second position X4 to the first position X3. Further, the abutting lever 110a is moved from the first position X3 to the second position X4 by being pressed by the carriage 33.

[0169] With this configuration, it is possible to suppress an increase in cost, an increase in weight of the device, and a large size, without a dedicated power source for moving the abutting lever 110a.

[0170] Further, the first position X3 and the second position X4 are located within a movement region of the carriage 33 at the time when the recording head 34 performs recording on the medium. Thus, it is possible to suppress a case where the movement region of the carriage 33 is enlarged along with the setting of the first position X3 and the second position X4, and thus it is possible to suppress a large size of the device.

[0171] However, the first position X3 and the second position X4 can also be located outside the movement region of the carriage 33 at the time when the recording head 34 performs recording on the medium.

[0172] Further, the initial position X0, which is a position of the carriage 33 and which caps the recording head 34, is set at one side with respect to a center position Xc in the movement region Al of the carriage 33 at the time when the recording head 34 performs recording on the medium, and the first position X3 and the second position X4 are arranged at the other side with respect to the center position Xc. Although a movement action of the carriage 33 is sometimes generated in the vicinity of the initial position X0 of the carriage 33 in order to perform maintenance of the recording head 34, since the initial position X0 is set at one side with respect to the center position Xc and the first position X3 and the second position X4 are arranged at the other side, it is possible to avoid a case where the abutting lever 110a interferes with the maintenance of the recording head 34.

[0173] However, the first position X3 and the second position X4 can also be located at the same side as the initial position X0 with respect to the center position Xc.

[0174] Further, the first position X3 and the second position X4 are located at different positions from the initial position X0, and after the medium Pt on which the nozzle check pattern CP is recorded is fed into the reading path T5, the carriage 33 is moved to the initial position X0 before starting reading of the nozzle check pattern CP (step S109). Figure 12 Thus, drying of an ink ejection nozzle (not shown) of the recording head 34 is suppressed, and it is possible to maintain appropriate recording quality.

[0175] Thus, drying of an ink ejection nozzle (not shown) of the recording head 34 is suppressed, and it is possible to maintain appropriate recording quality.

[0176] Further, the abutting lever 110a obtains power from the conveyance drive roller 21, and retreats from a position where the abutting lever 110a can abut against the carriage 33 by forward rotation of the conveyance drive roller 21, and enters the position where the abutting lever 110a can abut against the carriage 33 by reverse rotation of the conveyance drive roller 21. With this configuration, it is possible to suppress an increase in cost, an increase in weight of the device, and a large size, without a dedicated power source for driving the abutting lever 110a.

[0177] Next, the structure and mounting structure of the reading unit 50 will be described.

[0178] As shown in Figs. 17(A), 17(B), the reading unit 50 is fixed to the screw hole 80b formed in the left frame 80 on the left frame 80 side by the screw 82. Figure 15 , Figure 16 As shown in Figs. 17(A), 17(B), the reading unit 50 is fixed to the screw hole 80b formed in the left frame 80 on the left frame 80 side by the screw 82.

[0179] In the left frame 80, a left opening portion 80a is formed, and in the right frame 81, a right opening portion 81a is formed, and the reading unit 50 passes through and is fixed in the left opening portion 80a and the right opening portion 81a. That is, the reading unit 50 can be attached and detached with respect to the left frame 80 and the right frame 81, and is supported by the left opening portion 80a and the right opening portion 81a in the mounted state.

[0180] When the reading unit 50 is mounted, in the present embodiment, the reading unit 50 is inserted from the +X direction into the left opening portion 80a of the left frame 80 and is moved toward the right opening portion 81a. However, it is not limited thereto, and it can also be a structure in which the reading unit 50 is inserted from the -X direction at the right opening portion 81a and is moved toward the left opening portion 80a.

[0181] As shown in Figs. 17(A), 17(B), the reading unit 50 is fixed to the screw hole 80b formed in the left frame 80 on the left frame 80 side by the screw 82.

[0182] Further, as shown in Figs. 18(A), 18(B), the reading unit 50 is fixed to the screw hole 81b formed in the right frame 81 on the right frame 81 side by the screw 82.

[0183] The reading unit 50 is in a state of protruding by a predetermined length in the +X direction from the left frame 80 and in the -X direction from the right frame 81 in the mounted state.

[0184] Figure 19 ​In order to express a diagram of the position of the reading unit 50 with respect to the left frame 80 and the right frame 81, the shapes of the left frame 80 and the right frame 81 are shown slightly simplified for convenience. The reading unit 50 protrudes from the left opening portion 80a of the left frame 80 by a length Xt1 in the +X direction. Further, the reading unit 50 protrudes from the right opening portion 81a of the right frame 81 by a length Xt2 in the -X direction. In the present embodiment, the length Xt1 is longer than the length Xt2. However, it can also be configured such that the length Xt2 is longer than the length Xt1, or the length Xt1 and the length Xt2 can be the same.

[0185] In the present embodiment, a circuit board 85 is arranged in the region of the length Xt1 as shown in Figure 15 .

[0186] Further, in Figure 19 , the length Xu is the length of the reading unit 50 in the X-axis direction, and the region Xs is a readable region of the sensor module 51 (described later) in the X-axis direction. As shown in the figure, the readable region Xs also protrudes from the left opening portion 80a of the left frame 80 in the +X direction, and further, protrudes from the right opening portion 81a of the right frame 81 in the -X direction.

[0187] Further, in Figure 19 , the region Xp is a medium conveying region of the reading path T5, that is, a region in which a medium can pass through. The size (length in the X-axis direction) of the medium conveying region Xp is set to a size that has a slight margin with respect to the maximum size of the medium that is permitted.

[0188] Next, the structure of the reading unit 50 will be described in detail. Note that in the structure of the reading unit 50 described below, the mounting structure of the reading unit 50 with respect to the left frame 80 and the right frame 81 is not essential.

[0189] As shown in Figure 20 , Figure 21 , the reading unit 50 includes a housing structure 50a in which a sensor module 51 is housed, and the sensor module 51. The detailed structure of the sensor module 51 is omitted, but includes a light-receiving element, a light source, a lens array, and the like.

[0190] The housing structure 50a includes a first housing member 54, a second housing member 55, and a glass plate 53. In the present embodiment, the first housing member 54 and the second housing member 55 are formed of a resin material.

[0191] The first housing component 54 is box-shaped to house the sensor module 51, and has two screw holes 54b near each end in the X-axis direction. In the second housing component 55, a screw insertion hole 55e is formed at a position corresponding to the screw holes 54b. The first housing component 54 and the second housing component 55 are fixed by passing a screw 57 through the screw insertion hole 55e and engaging it with the screw hole 54b. Furthermore, as will be explained later, in addition to being fixed by screws 57, the first housing component 54 and the second housing component 55 are also bonded together with double-sided tape.

[0192] Spring retaining portions 54a are formed near both ends in the X-axis direction in the first housing member 54, and a spring 56, as an example of a pressing member, is held in the spring retaining portions 54a. In this embodiment, the spring 56 is a compression helical spring. The sensor module 51 is movable in the B-axis direction within the housing structure 50a, and the spring 65 presses the sensor module 51 toward the -B direction, i.e., the second housing member 55.

[0193] Two sensor-side abutment portions 51a are formed at both ends of the sensor module 51 in the X-axis direction. Furthermore, at both ends of the second housing member 55 in the X-axis direction, as... Figure 23 The cover-side abutment portion 55d is formed as shown. Moreover, as shown in Figures 24(A) and 24(B), the sensor-side abutment portion 51a is pressed against the cover-side abutment portion 55d by the pressing force of the spring 56, thereby defining the position of the sensor module 51 relative to the second cover component 55 and the glass plate 53.

[0194] The second housing component 55 has an opening 55b, and covering portions 55c are formed relative to the opening 55b in the +X and -X directions, respectively. The covering portion 55c serves as a reference. Figure 19 The part of the readable region Xs described is covered.

[0195] exist Figure 22 In the diagram, the regions indicated by symbols Xm1 and Xm2 (hereinafter referred to as "coverage regions") are the regions of the coverage portion 55c in the X-axis direction. Coverage region Xm1 is the region that covers the +X direction side of the readable region Xs of the sensor module 51, and coverage region Xm2 is the region that covers the -X direction side of the readable region Xs of the sensor module 51.

[0196] The area indicated by the symbol Xk is the region within the readable region Xs that is not covered by the covered portion 55c, i.e., the actual readable region. The actual readable region Xk is also the area exposed by the glass plate 53. The actual readable region Xk and the media transport region Xp (refer to...) Figure 19 It is roughly equal to, or slightly larger than, the medium transport area Xp.

[0197] The glass plate 53 is adhered to the inner side of the second housing member 55. In the present embodiment, a symbol 61 is a double-sided tape for glass plate adhesion, and the glass plate 53 is adhered and fixed to the inner side of the second housing member 55 by the double-sided tape for glass plate adhesion 61. The double-sided tape for glass plate adhesion 61 is adhered to the inner side of the cover portion 55c, and is arranged in a manner of surrounding the opening portion 55b. Figure 23

[0198] In addition, between the first housing member 54, the second housing member 55, and the glass plate 53, a double-sided tape for housing member adhesion 62 is provided as shown in FIG. 6, and the first housing member 54 and the second housing member 55 are adhered together by the double-sided tape for housing member adhesion 62, and further, the first housing member 54 and the glass plate 53 are adhered together. Further, in particular, since the double-sided tape for housing member adhesion 62 is arranged in a manner of covering the gap Bb between the glass plate 53 and the second housing member 55, it is possible to suppress the case where foreign matter intrudes into the inside of the housing structure 50a via the gap Bb. Figure 25

[0199] Next, a sheet material 60 is adhered to the guide portion 55a formed on the second housing member 55. The sheet material 60 is a material whose coefficient of friction with the medium Pt is lower than the coefficient of friction between the second housing member 55 and the medium P, and as one example, a low-friction sheet formed of ultra-high molecular weight PE (Poly Ethylene), or PTFE (Poly TetraFluoro Ethylene), or the like can be used.

[0200] By adhering such a sheet material 60 to the guide portion 55a, the medium Pt conveyed in the A-axis direction can smoothly advance in the A-axis direction. In particular, since the medium Pt can be smoothly advanced in the +A direction by the sheet material 60, it is possible to improve the reading accuracy.

[0201] A part of the sheet material 60 is sandwiched between the first housing member 54 and the second housing member 55 as shown by a symbol 60a. Further, the sheet material 60 is extended to the surface of the glass plate 53 in a manner of covering the gap Ba between the glass plate 53 and the second housing member 55. Thereby, it is possible to suppress the case where foreign matter intrudes into the inside of the housing structure 50a via the gap Ba.

[0202] ​​As explained above, the left frame 80 and right frame 81, which support the reading unit 50, are arranged spaced apart in the width direction. An opening for the reading unit 50 to pass through is provided on at least one of the left frame 80 and right frame 81. In this embodiment, openings (left opening 80a and right opening 81a) are formed on both frames. Furthermore, the left frame 80 and right frame 81 support the reading unit 50, which passes between the left frame 80 and right frame 81.

[0203] Therefore, compared with the structure in which the left frame 80 and the right frame 81 have cutouts at the top and the reading unit 50 falls into the cutouts from above, the rigidity of the left frame 80 and the right frame 81 can be ensured.

[0204] Furthermore, the feature is that the distance between the left frame 80 and the right frame 81 in the width direction (in Figure 19 The distance Xf is shorter than the length of the read unit 50 in the width direction (in the middle). Figure 19 The length is Xu).

[0205] Therefore, compared to a structure where the reading unit 50 is supported by the left frame 80 and right frame 81 via additional components, cost increases can be suppressed. Furthermore, since the distance Xf between the left frame 80 and right frame 81 can be shortened within the range where the medium can be transported, it contributes to the miniaturization of the device.

[0206] Furthermore, in this embodiment, since the openings for the reading unit 50 to pass through are provided on both the left frame 80 and the right frame 81 (left opening 80a and right opening 81a), the posture of the reading unit 50 is stable. Alternatively, the opening may be provided on at least one of the frames, and a recess for accommodating one end of the reading unit 50 may be provided on the other. That is, one frame may be a through hole, and the other a non-through hole.

[0207] Furthermore, the reading unit 50 has a sensor module 51 for reading the medium, and in the width direction, the sensor module 51 can read the size of the medium (in... Figure 19 The length of the readable area Xs is greater than the media transport area on the media transport path (in...). Figure 19 The middle area is the medium transport region (Xp). The sensor module 51 here can read the size of the medium (in... Figure 19 The length of the readable area (Xs) refers to the size of the readable medium in the state before the sensor module 51 is installed on the device body 2.

[0208] This structure eliminates the need for the sensor module 51 to be sized to fit the media delivery area Xp. This increases the flexibility in selecting the sensor module 51, reduces its cost, and consequently contributes to a lower overall cost of the device.

[0209] For example, as sensor module 51, it is possible to use the most widely available and inexpensive sensor module.

[0210] However, in the width direction, the size of the medium that the sensor module 51 can read can be the same as the medium delivery area Xp, or the size of the medium that the sensor module 51 can read can be smaller than the medium delivery area Xp. That is, it only needs to be the size of the nozzle inspection pattern Cp described above.

[0211] Furthermore, the reading unit 50 includes a housing structure 50a for housing the sensor module 51. The housing structure 50a includes a glass plate 53 located between the reading path T5 and the sensor module 51, a first housing member 54 for holding the sensor module 51, and a second housing member 55 opposite to the first housing member 54 and holding the glass plate 53. By housing the sensor module 51 in such a housing structure 50a, the reduction in reading accuracy caused by the adhesion of foreign objects to the sensor module 51 can be suppressed.

[0212] Furthermore, the second housing component 55 has a housing-side abutment portion 55d that can abut against the reading unit 50. The sensor module 51 is housed in a manner that allows it to move forward and backward relative to the housing-side abutment portion 55d, and is pressed against the housing-side abutment portion 55d by a spring 56. As a result, the position of the sensor module 51 relative to the second housing component 55, i.e., the glass plate 53, is stable, improving reading accuracy.

[0213] Furthermore, the second housing component 55 has a cover portion 55c, which covers a portion of the sensor module 51 in the width direction and the medium transport area on the medium transport path (in Figure 19 The area deviated from the medium transport area (Xp) is covered. This reduces the area of ​​the glass plate 53 and helps to curb cost increases.

[0214] In addition, such as Figure 23 As shown, a portion of the cover 55c overlaps with a portion of the glass plate 53 when viewed from the normal direction (B-axis direction) relative to the surface of the glass plate 53. With this structure, it is possible to prevent foreign objects from intruding into the interior of the casing structure 50a through the gap between the glass plate 53 and the cover 55c.

[0215] However, it can also be configured so that the cover portion 55c does not overlap with a portion of the glass plate 53 when viewed from the normal direction (B-axis direction) with respect to the face of the glass plate 53.

[0216] Further, as described with reference to Figure 25 As described above, the second housing member 55 and the glass plate 53 are adhered together by the glass-plate-adhesion double-sided tape 61, and at least a portion of the glass-plate-adhesion double-sided tape 61 is interposed between the cover portion 55c and the glass plate 53. Thereby, it is possible to suppress the intrusion of foreign matter into the inside of the housing structure 50a from the gap between the glass plate 53 and the cover portion 55c.

[0217] However, the adhesion between the second housing member 55 and the glass plate 53 is not limited to the double-sided tape, and can be implemented by an adhesive or the like.

[0218] Further, as described with reference to Figure 25 the first housing member 54 and the second housing member 55 are adhered together by the housing-member-adhesion double-sided tape 62, it is possible to easily adhere the first housing member 54 and the second housing member 55 in operation, and it is possible to suppress the intrusion of foreign matter into the inside of the housing structure 50a from between the first housing member 54 and the second housing member 55.

[0219] In addition, although in the present embodiment, the second housing member 55 is fixed with respect to the first housing member 54 by the screw 57 (refer to Figure 20 ) and the housing-member-adhesion double-sided tape 62, it can be fixed by only either of the screw and the double-sided tape.

[0220] Further, since the second housing member 55 has the guide portion 55a that guides the medium toward the reading position read by the sensor module 51, the medium can smoothly pass through when passing from the position of the second housing member 55. Also, since the sheet material 60 having a lower coefficient of friction than the medium is provided on the guide portion 55a, the medium can more smoothly pass through when passing from the position of the second housing member 55.

[0221] In addition, instead of providing the sheet material 60, the guide portion 55a can be formed of a low-friction material such as POM (Polyoxymethylene).

[0222] Further, as described with reference to Figure 25 the first housing member 54 and the second housing member 55 sandwich a portion of the sheet material 60, it is possible to suppress the detachment of the sheet material 60 from the second housing member 55.

[0223] Furthermore, due to the reference Figure 25 As explained, a portion of the sheet material 60 covers the boundary line Ba between the second housing component 55 and the glass plate 53, thus preventing foreign objects from intruding into the interior of the housing structure 50a from the boundary line Ba. Furthermore, although in this embodiment the sheet material 60 covers approximately the entire area of ​​the boundary line Ba in the X-axis direction, it may also cover only a portion of the boundary line Ba in the X-axis direction.

[0224] As described above, the reading unit 50 is a reading unit that, in a printer 1 having a left frame 80 and a right frame 81 arranged at intervals in the width direction, passes between the left frame 80 and the right frame 81 through an opening formed on at least one of the left frame 80 and the right frame 81, is supported by the left frame 80 and the right frame 81, and reads the medium conveyed on the reading transport path T5. Furthermore, the reading unit 50 includes a sensor module 51 larger than the medium transport area Xp in the reading path T5, and a housing structure 50a for housing the sensor module 51. The housing structure 50a includes a glass plate 53 located between the read transport path T5 and the sensor module 51, a first housing member 54 that holds the sensor module 51, and a second housing member 55 that is opposite to the first housing member 54 and holds the glass plate 53. The second housing member 55 has a covering portion 55c that covers a portion of the sensor module 51 in the width direction and an area offset from the media transport area Xp on the read path T5. This reduces the area of ​​the glass plate 53, thereby suppressing cost increases.

[0225] The present invention is not limited to the embodiments or variations described above, and various modifications can be made within the scope of the invention described in the technical solution. Of course, these modifications are also included within the scope of the present invention.
