[Modes for carrying out the invention]

[0009] Hereinafter, a media conveyance device according to an embodiment disclosed in the present application will be described with reference to the drawings. Note that the technology of the present disclosure is not limited by the following description. Also, in the following description, the same reference numerals are given to the same components, and duplicate explanations are omitted.

Example

[0010] As shown in FIG. 1, the media conveyance device of the example is provided in an image reading device 1. FIG. 1 is a perspective view showing the image reading device 1 provided with the media conveyance device of the example. The image reading device 1 includes a media conveyance device main body 2, a scan button 3, a power lamp 5, a paper feed tray 6, and a paper discharge tray 7. The media conveyance device main body 2 is generally formed in a box shape. The scan button 3 is disposed on the upper side of the media conveyance device main body 2. The scan button 3 detects whether or not the scan button 3 has been pressed. The power lamp 5 is disposed on the front side on the upper side of the media conveyance device main body 2. The power lamp 5 is formed of a light emitting diode.

[0011] The paper feed tray 6 includes a paper feed tray main body 11 and a paper feed tray extension member 12. The paper feed tray main body 11 is formed in a plate shape. A paper feed tray placement surface 14 is formed on the paper feed tray main body 11. Inside the paper feed tray main body 11, a space for storing the paper feed tray extension member 12 is formed. The paper feed tray main body 11 is supported by the media conveyance device main body 2 so as to be rotatable about a rotation axis 15. The rotation axis 15 is parallel to a plane along which an installation surface on which the image reading device 1 is placed extends. The paper feed tray main body 11 opens and closes by rotating about the rotation axis 15.

[0012] The paper feed tray extension member 12 is formed in a plate shape. The paper feed tray extension member 12 has a paper feed tray auxiliary mounting surface 16 formed on it. The paper feed tray extension member 12 is positioned such that the paper feed tray auxiliary mounting surface 16 generally follows the plane along which the paper feed tray mounting surface 14 follows, and is supported by the paper feed tray body 11 so as to be rotatable around a rotation axis 17. The rotation axis 17 is perpendicular to the plane along which the paper feed tray mounting surface 14 follows. The paper feed tray 6 extends and retracts as the paper feed tray extension member 12 rotates around the rotation axis 17. The paper feed tray extension member 12 is positioned in the extended paper feed tray position when the paper feed tray 6 is properly extended, and is located outside the paper feed tray body 11.

[0013] The paper feed tray 6 is deployed or stored in the media transport device body 2 by opening and closing the paper feed tray body 11 or by extending and retracting the paper feed tray 6. The paper feed tray extension member 12 is positioned in the paper feed tray extended position when the paper feed tray 6 is properly deployed. The paper feed tray body 11 is positioned in the paper feed tray deployed position when the paper feed tray 6 is properly deployed. The paper feed tray mounting surface 14 is facing diagonally upward when the paper feed tray body 11 is positioned in the paper feed tray deployed position.

[0014] Figure 2 is another perspective view showing the image reading device 1. The image reading device 1 further includes a blind cover 18. The blind cover 18 is generally formed in a plate shape. The blind cover 18 is located at the rear of the media transport device body 2 and is supported by the media transport device body 2 so as to be rotatable around a rotation axis 19. The rotation axis 19 is parallel to the rotation axis 15. The blind cover 18 opens and closes as the blind cover 18 rotates around the rotation axis 19. The blind cover 18 is in the open position when the blind cover 18 is properly open.

[0015] Figure 3 is a cross-sectional view showing the image reading device 1. The output tray 7 comprises an output tray body 21 and an output tray extension member 22. The output tray body 21 is formed in a plate shape. An output tray mounting surface 23 is formed on the output tray body 21. Inside the output tray body 21, there is a storage space for storing the output tray extension member 22. The output tray body 21 is supported by the media transport device body 2 so as to be rotatable around a rotation axis 24. The rotation axis 24 is parallel to the rotation axis 15. The plane along which the output tray mounting surface 23 is parallel to the rotation axis 24. The output tray body 21 opens and closes as the output tray body 21 rotates around the rotation axis 24.

[0016] The paper output tray extension member 22 is formed in a plate shape. The paper output tray extension member 22 has a paper output tray auxiliary mounting surface 25 formed on it. The paper output tray extension member 22 is positioned such that the paper output tray auxiliary mounting surface 25 generally aligns with the plane along which the paper output tray mounting surface 23 aligns, and is supported by the paper output tray body 21 so as to be able to translate parallel to the translational direction 26. The translational direction 26 is parallel to the plane along which the paper output tray mounting surface 23 aligns, and is perpendicular to the rotation axis 24. The tip 27 of the paper output tray extension member 22 that is farther from the rotation axis 24 moves closer to or further away from the paper output tray body 21 as the paper output tray extension member 22 translates parallel to the translational direction 26. The paper output tray 7 extends and retracts as the paper output tray extension member 22 translates parallel to the translational direction 26. The paper output tray extension member 22 is positioned in the extended position of the paper output tray when the paper output tray 7 is properly extended, and is located outside the paper output tray body 21.

[0017] The output tray 7 is deployed or stored in the media transport device body 2 by the opening and closing of the output tray body 21 or by the extension and retraction of the output tray 7. The output tray extension member 22 is positioned in the output tray extended position when the output tray 7 is properly deployed. The output tray body 21 is positioned in the output tray deployed position when the output tray 7 is properly deployed. The output tray mounting surface 23 faces diagonally upward when the output tray body 21 is positioned in the output tray deployed position.

[0018] The media transport device body 2 has an insertion port 31, an outlet port 32, and a transport path 33. The insertion port 31 is located on the rear side of the media transport device body 2. The outlet port 32 is located on the front upper side of the media transport device body 2. The transport path 33 is located inside the media transport device body 2. The insertion port 31 and the outlet port 32 are connected via the transport path 33. The outlet port 32 is connected to the paper output tray body 21 and to the paper output tray mounting surface 23 when the paper output tray body 21 is in the paper output tray deployed position.

[0019] The image reading device 1 further comprises a transport unit 37 and a reading unit 38. The transport unit 37 is located inside the media transport device body 2. The transport unit 37 supplies one of several media inserted into the insertion port 31 to the transport path 33. The transport unit 37 further transports the one medium supplied to the transport path 33 along the transport path 33 toward the discharge port 32. The transport unit 37 further discharges the medium that has been transported along the transport path 33 from the discharge port 32. The reading unit 38 captures an image of the medium being transported along the transport path 33.

[0020] Figure 4 is a cross-sectional view showing the image reading device 1 when the blind cover 18 is open and the paper feed tray 6 is deployed. The insertion opening 31 is open and not covered by the blind cover 18 when the blind cover 18 is in the open position. The image reading device 1 further includes a cover closing spring 39. The cover closing spring 39 is formed from a torsion coil spring. One end of the cover closing spring 39 is fixed to the media transport device body 2, and the other end of the cover closing spring 39 is fixed to the blind cover 18. The cover closing spring 39 elastically deforms and provides an elastic force to the blind cover 18 so that the blind cover 18 moves toward the closed position.

[0021] The base end 35 of the paper feed tray body 11, which is closer to the rotation axis 15, moves closer to or further away from the insertion opening 31 as the paper feed tray body 11 rotates relative to the media transport device body 2. The base end 35 is located near the insertion opening 31 when the cover 18 is in the open position and the paper feed tray body 11 is in the paper feed tray deployed position. The insertion opening 31 is connected to the paper feed tray body 11 and to the paper feed tray mounting surface 14 of the paper feed tray body 11 when the paper feed tray body 11 is in the paper feed tray deployed position.

[0022] Figure 5 is a cross-sectional view showing the image reading device 1 when the output tray 7 is retracted, the feed tray 6 is retracted, and the cover 18 is closed. The output tray 7 is shortened when it is properly retracted into the media transport device body 2. The output tray extension member 22 is positioned in the shortened output tray position and is stored inside the output tray body 21 when the output tray 7 is properly shortened. The output tray body 21 is positioned in the retracted output tray position when the output tray 7 is properly retracted. The output tray mounting surface 23 of the output tray body 21 faces upward when the output tray body 21 is positioned in the retracted output tray position.

[0023] The paper feed tray 6 is shortened when it is properly stored in the media transport device body 2. The paper feed tray extension member 12 is positioned in the shortened paper feed tray position and is stored inside the paper feed tray body 11 when the paper feed tray 6 is properly shortened. The paper feed tray body 11 is positioned in the stored paper feed tray position and is placed on top of the output tray 7 when the paper feed tray 6 is properly stored. The paper feed tray mounting surface 14 of the paper feed tray body 11 faces downwards, opposite the output tray 7 stored in the media transport device body 2, and faces the output tray mounting surface 23 of the output tray body 21 when the paper feed tray body 11 is in the stored paper feed tray position.

[0024] The paper feed tray body 11 covers the paper output tray 7 and the output port 32 so that they are not exposed to the upper side of the media transport device body 2 when the paper output tray 7 and the paper feed tray 6 are properly stored. Figure 6 is a perspective view showing the image reading device 1 when the paper output tray 7 and the paper feed tray 6 are stored. The image reading device 1 can prevent foreign matter from entering the transport path 33 through the output port 32 when the output port 32 is covered by the paper feed tray body 11.

[0025] The blind cover 18 is positioned in a closed position when closed, as shown in Figure 5, and covers the insertion opening 31 and the output tray 7 so that they are not exposed to the rear side of the media transport device body 2. The image reading device 1 can prevent foreign objects from entering the transport path 33 through the insertion opening 31 when the insertion opening 31 is covered by the blind cover 18. Figure 7 is another perspective view showing the image reading device 1 when the output tray 7 is retracted, the paper feed tray 6 is retracted, and the blind cover 18 is closed. When the output tray 7 is retracted, the paper feed tray 6 is retracted, and the blind cover 18 is closed, the image reading device 1 is generally box-shaped and is smaller than when the output tray 7 is unfolded, the paper feed tray 6 is unfolded, and the blind cover 18 is open. The image reading device 1 is small enough to be stored in a small space.

[0026] Figure 8 is a perspective view showing the blind cover 18. The blind cover 18 comprises a cover shell 41, a plurality of longitudinal reinforcing ribs 42, a plurality of transverse reinforcing ribs 43, and contact ribs 44. The cover shell 41 is formed in a plate shape and forms the rear outer shell of the blind cover 18. The plane along which the cover shell 41 is aligned is parallel to the axis of rotation 19. The plurality of longitudinal reinforcing ribs 42 are each formed in a strip shape. The plurality of longitudinal reinforcing ribs 42 are arranged on the front side of the cover shell 41 so as to be aligned with a plurality of parallel planes and are integrally joined to the cover shell 41. The plurality of parallel planes along which the plurality of longitudinal reinforcing ribs 42 are each aligned are perpendicular to the axis of rotation 19, that is, perpendicular to the plane along which the cover shell 41 is aligned. The plurality of transverse reinforcing ribs 43 are each formed in a strip shape. The plurality of transverse reinforcing ribs 43 are arranged on the front side of the cover shell 41 so as to be aligned with a plurality of parallel planes and are integrally joined to the cover shell 41. Multiple parallel planes along which each of the multiple transverse reinforcing ribs 43 follows are parallel to the axis of rotation 19 and perpendicular to the plane along which the cover shell 41 follows. Multiple longitudinal reinforcing ribs 42 and multiple transverse reinforcing ribs 43 reinforce the cover shell 41 so that it does not bend. The contact rib 44 is formed in a strip shape. The contact rib 44 is positioned in the center of the cover cover 18 in the width direction parallel to the axis of rotation 19 and is positioned so as to follow a plane perpendicular to the axis of rotation 19. The contact rib 44 is integrally joined to the cover shell 41. The contact rib 44, like the multiple longitudinal reinforcing ribs 42 and multiple transverse reinforcing ribs 43, reinforces the cover shell 41 so that it does not bend.

[0027] Figure 9 is an enlarged cross-sectional view showing the image reading device 1 when the output tray 7 is retracted, the feed tray 6 is retracted, and the cover 18 is closed. The base end 35 of the feed tray body 11 is located away from the insertion opening 31 and towards the upper rear of the image reading device 1 when the feed tray body 11 is in the feed tray retracted position. The insertion opening 31 is covered and closed by the cover 18 when the feed tray 6 is properly retracted into the media transport device body 2 and the cover 18 is in the closed position. The contact rib 44 is in contact with or near the tip 27 of the output tray extension member 22 when the output tray 7 is properly retracted into the media transport device body 2 and the cover 18 is in the closed position.

[0028] The upper end 36 of the cover 18 on the side furthest from the rotation axis 19 moves forward or backward as the cover 18 rotates around the rotation axis 19 when the paper feed tray 6 is properly stored in the media transport device body 2. In other words, as the cover 18 rotates around the rotation axis 19 when the paper feed tray 6 is properly stored in the media transport device body 2, the upper end 36 of the cover 18 moves closer to or further away from the base end 35 of the paper feed tray body 11. When the paper feed tray 6 is properly stored in the media transport device body 2 and the cover 18 is in the closed position, the upper end 36 is in contact with or near the base end 35 of the paper feed tray body 11, as shown in Figure 10. Figure 10 is a top view showing the image reading device 1 when the output tray 7 is stored, the paper feed tray 6 is stored, and the cover 18 is closed. In other words, the size of the gap between the upper end 36 of the cover 18 and the base end 35 of the paper tray body 11 is narrower than a predetermined value when the paper tray 6 is properly stored in the media transport device body 2 and the cover 18 is in the closed position.

[0029] Figure 11 is an enlarged cross-sectional view showing the image reading device 1 when the output tray 7 is retracted. The output tray 7 is positioned so as not to overlap with the area through which the paper feed tray body 11 passes when the paper feed tray body 11 is opened and closed, when the output tray 7 is properly retracted into the media transport device body 2. In other words, the image reading device 1 is designed so that the output tray 7 does not obstruct the movement of the paper feed tray body 11 toward the paper feed tray deployed position when the output tray 7 is properly retracted into the media transport device body 2.

[0030] As shown in Figure 12, when the paper output tray body 21 is positioned in the paper output tray storage position, the paper output tray extension member 22 may be positioned in an improper shortened position instead of the paper output tray shortened position. Figure 12 is an enlarged cross-sectional view showing the image reading device 1 when the paper output tray body 21 is in the paper output tray storage position and the paper output tray extension member 22 is positioned in an improper shortened position. The improper shortened position is different from the paper output tray shortened position and different from the paper output tray extended position, and represents a position between the paper output tray shortened position and the paper output tray extended position. When the paper output tray extension member 22 is positioned in an improper shortened position, the paper output tray extension member 22 is improperly stored in the paper output tray body 21. When the paper output tray body 21 is in the paper output tray storage position and the paper output tray extension member 22 is positioned in an improper shortened position, the paper output tray 7 is improperly stored in the media transport device body 2.

[0031] The cover 18 is positioned in the intermediate cover position when the output tray 7 is improperly stored in the media transport device body 2 and the contact rib 44 contacts the tip 27 of the output tray extension member 22. The intermediate cover position is different from the open position and different from the closed position, and represents a position between the open position and the closed position. The upper end 36 of the cover 18 is separated from the base side end 35 of the paper feed tray body 11 when the cover 18 is positioned in the intermediate cover position. Figure 13 is a top view showing the image reading device 1 when the cover 18 is positioned in the intermediate cover position. The size of the gap 46 between the upper end 36 of the cover 18 and the base side end 35 of the paper feed tray body 11 is greater than a predetermined value when the paper feed tray 6 is properly stored in the media transport device body 2 and the cover 18 is positioned in the intermediate cover position.

[0032] Figure 14 is a block diagram of the image reading device 1. The image reading device 1 further includes a paper feed tray extension mechanism 51, a cover opening mechanism 52, an output tray opening / closing mechanism 53, and an output tray extension mechanism 54. The paper feed tray extension mechanism 51 mechanically converts the rotation of the paper feed tray body 11 into the rotation of the paper feed tray extension member 12. In detail, when the paper feed tray body 11 moves toward the paper feed tray deployed position, the paper feed tray extension mechanism 51 moves the paper feed tray extension member 12 toward the paper feed tray extended position in conjunction with the rotation of the paper feed tray body 11. The paper feed tray extension mechanism 51 further positions the paper feed tray extension member 12 toward the paper feed tray extended position when the paper feed tray body 11 is positioned toward the paper feed tray deployed position. When the paper feed tray body 11 moves toward the paper feed tray retracted position, the paper feed tray extension mechanism 51 moves the paper feed tray extension member 12 toward the paper feed tray shortened position in conjunction with the rotation of the paper feed tray body 11. The paper tray extension mechanism 51 further positions the paper tray extension member 12 in the shortened position when the paper tray body 11 is positioned in the paper tray storage position.

[0033] The cover release mechanism 52 pushes the blind cover 18 against the elastic force of the cover closing spring 39 when the paper tray body 11 moves toward the paper tray deployed position, moving the blind cover 18 toward the open position. The cover release mechanism 52 further places the blind cover 18 toward the open position when the paper tray body 11 is positioned toward the paper tray deployed position. The cover release mechanism 52 releases the blind cover 18 so that the blind cover 18 moves toward the closed position due to the elastic force of the cover closing spring 39 when the paper tray body 11 moves toward the paper tray stored position. The cover release mechanism 52 releases the blind cover 18 so that the blind cover 18 moves toward the closed position due to the elastic force of the cover closing spring 39 when the paper tray body 11 is positioned toward the paper tray stored position.

[0034] The output tray opening / closing mechanism 53 moves the output tray body 21 toward the output tray unfolded position when the media is transported along the transport path 33 by the transport unit 37, and positions the output tray body 21 in the output tray unfolded position. After all of the media inserted into the insertion opening 31 has been ejected from the output opening 32, the output tray opening / closing mechanism 53 moves the output tray body 21 toward the output tray storage position, and positions the output tray body 21 in the output tray storage position.

[0035] The paper output tray extension mechanism 54 mechanically converts the rotation of the paper output tray body 21 into translational motion of the paper output tray extension member 22. Specifically, when the paper output tray body 21 moves toward the paper output tray deployed position, the paper output tray extension mechanism 54 translates the paper output tray extension member 22 toward the paper output tray extended position in conjunction with the rotation of the paper output tray body 21. Furthermore, when the paper output tray body 21 is positioned in the paper output tray deployed position, the paper output tray extension mechanism 54 positions the paper output tray extension member 22 toward the paper output tray extended position. When the paper output tray body 21 moves toward the paper output tray retracted position, the paper output tray extension mechanism 54 translates the paper output tray extension member 22 toward the paper output tray shortened position in conjunction with the rotation of the paper output tray body 21. Furthermore, when the paper output tray body 21 is positioned in the paper output tray retracted position, the paper output tray extension mechanism 54 positions the paper output tray extension member 22 toward the paper output tray shortened position.

[0036] The image reading device 1 further includes a paper feed tray storage sensor 55, a cover closing sensor 56, and a control device 57. The paper feed tray storage sensor 55 is located inside the media transport device body 2. The paper feed tray storage sensor 55 detects whether the paper feed tray body 11 is in the paper feed tray storage position. The cover closing sensor 56 is located inside the media transport device body 2. The cover closing sensor 56 detects whether the cover 18 is in the closed position.

[0037] The control device 57 is a computer and includes, for example, a storage device and a CPU (Central Processing Unit), which are not shown. The storage device records computer programs installed in the control device 57 and records information used by the CPU. The CPU processes information and controls the storage device by executing computer programs installed in the control device 57. The CPU also controls the power lamp 5, the paper tray storage sensor 55, and the cover closing sensor 56 by executing computer programs installed in the control device 57.

[0038] The control device 57 controls the power lamp 5 so that it turns off when the paper tray storage sensor 55 detects that the paper feed tray body 11 is in the paper tray storage position. The control device 57 controls the power lamp 5 so that it turns on when the paper tray storage sensor 55 detects that the paper feed tray body 11 is not in the paper tray storage position. When the control device 57 detects that the paper feed tray body 11 is in the paper tray storage position and that the cover 18 is in the closed position, it determines that the paper output tray extension member 22 is properly positioned in the paper output tray shortened position. That is, the cover closing sensor 56 can detect that the paper output tray extension member 22 is in the paper output tray shortened position by detecting that the cover 18 is in the closed position. When the control device 57 detects that the paper feed tray body 11 is in the paper tray storage position and that the cover 18 is not in the closed position, it determines that the paper output tray extension member 22 is not in the paper output tray shortened position. The control device 57 controls the power lamp 5 so that it blinks when it determines that the paper output tray extension member 22 is not in the paper output tray shortened position.

[0039] [Operation of Image Reader 1] When a user wants to read images from multiple media using the image reading device 1, they move the paper feed tray body 11 toward the paper feed tray unfolded position and position the paper feed tray body 11 in the paper feed tray unfolded position. The paper feed tray extension member 12 moves toward the paper feed tray extended position by the paper feed tray extension mechanism 51 when the paper feed tray body 11 moves toward the paper feed tray unfolded position. The paper feed tray extension member 12 is positioned toward the paper feed tray extended position by the paper feed tray extension mechanism 51 when the paper feed tray body 11 is positioned toward the paper feed tray unfolded position. The paper feed tray 6 is properly unfolded when the paper feed tray body 11 is positioned toward the paper feed tray unfolded position and the paper feed tray extension member 12 is positioned toward the paper feed tray extended position.

[0040] The cover cover 18 moves towards the open position by the cover opening mechanism 52 against the elastic force of the cover closing spring 39 when the paper feed tray body 11 moves toward the paper feed tray deployed position. The cover cover 18 is positioned in the open position by the cover opening mechanism 52 when the paper feed tray body 11 is positioned toward the paper feed tray deployed position. The control device 57 controls the power lamp 5 to light up the power lamp 5 when the paper feed tray storage sensor 55 detects that the paper feed tray body 11 is not in the paper feed tray storage position.

[0041] The user places multiple media on the paper feed tray 6 so that they face the paper feed tray mounting surface 14 when the paper feed tray 6 is properly deployed. At this time, the image reading device 1 prevents the multiple media from shifting or falling due to the weight of the parts of the media that protrude from the paper feed tray body 11 by placing them on the paper feed tray extension member 12. When the multiple media are placed on the paper feed tray 6, gravity causes them to move towards the insertion slot 31 and be inserted into the insertion slot 31 because the paper feed tray mounting surface 14 is angled upward. After the multiple media are inserted into the insertion slot 31, the user presses the scan button 3.

[0042] The output tray opening / closing mechanism 53 moves the output tray body 21 toward the output tray unfolded position after the scan button 3 detects that the scan button 3 has been pressed, and positions the output tray body 21 in the output tray unfolded position. The output tray extension member 22 is translated toward the output tray extension position by the output tray extension mechanism 54 when the output tray body 21 moves toward the output tray unfolded position. The output tray extension member 22 is positioned toward the output tray extension position by the output tray extension mechanism 54 when the output tray body 21 is positioned toward the output tray unfolded position. The output tray 7 is properly unfolded when the output tray body 21 is positioned toward the output tray unfolded position and the output tray extension member 22 is positioned toward the output tray extension position.

[0043] After the scan button 3 detects that the scan button 3 has been pressed, the transport unit 37 supplies the multiple media inserted into the insertion slot 31 one by one to the transport path 33. The transport unit 37 then transports one of the media supplied to the transport path 33 along the transport path 33. The reading unit 38 captures an image of the media being transported along the transport path 33. The transport unit 37 discharges the media on which the image has been captured from the output port 32 and places the media on the output tray 7 so that the media on which the image has been captured faces the output tray mounting surface 23 and the output tray auxiliary mounting surface 25. The transport unit 37 and the reading unit 38 repeatedly transport the media and capture images of the media until all of the multiple media inserted into the insertion slot 31 are placed on the output tray 7. In this case, the image reading device 1 can prevent the media from shifting or falling due to the weight of the protruding portion of the media placed on the output tray 7, by having that portion rest on the output tray extension member 22.

[0044] The output tray opening / closing mechanism 53 moves the output tray body 21 toward the output tray storage position after all of the media have been placed on the output tray 7, and positions the output tray body 21 in the output tray storage position. The output tray extension member 22 is translated toward the output tray shortened position by the output tray extension mechanism 54 when the output tray body 21 moves toward the output tray storage position. The output tray extension member 22 is positioned toward the output tray shortened position by the output tray extension mechanism 54 when the output tray body 21 is positioned in the output tray storage position. After the output tray 7 is retracted, any portion of the media that protrudes from the output tray body 21 is placed on the paper feed tray 6 so as to face the paper feed tray mounting surface 14 of the paper feed tray 6.

[0045] After the user has finished reading images from multiple media, they remove the media from the image reading device 1, move the paper feed tray body 11 toward the paper feed tray storage position, and position the paper feed tray body 11 in the paper feed tray storage position. The paper feed tray extension member 12 moves toward the paper feed tray shortened position by the paper feed tray extension mechanism 51 when the paper feed tray body 11 moves toward the paper feed tray storage position. The paper feed tray extension member 12 is positioned in the paper feed tray shortened position by the paper feed tray extension mechanism 51 when the paper feed tray body 11 is positioned in the paper feed tray storage position. The paper feed tray 6 is properly stored in the media transport device body 2 when the paper feed tray extension member 12 is positioned in the paper feed tray shortened position and the paper feed tray body 11 is positioned in the paper feed tray storage position.

[0046] The cover 18 is released from the cover release mechanism 52 when the paper feed tray body 11 moves toward the paper feed tray storage position, and moves toward the closed position by the elastic force of the cover closing spring 39. The cover 18 is released from the cover release mechanism 52 when the output tray 7 and the paper feed tray 6 are properly stored in the media transport device body 2, and is positioned in the closed position by the elastic force of the cover closing spring 39, as shown in Figure 9. When the control device 57 detects that the paper feed tray body 11 is in the paper feed tray storage position and that the cover 18 is in the closed position, it controls the power lamp 5 to turn off the power lamp 5.

[0047] As shown in Figure 15, the output tray extension member 22 may be positioned in an improper shortened position instead of the output tray shortened position, even when the output tray body 21 is positioned in the output tray storage position. Figure 15 is an enlarged cross-sectional view showing the image reading device 1 when the output tray body 21 is positioned in the output tray storage position and the output tray extension member 22 is positioned in an improper shortened position. The malfunction of the output tray extension member 22 being positioned in an improper shortened position can occur, for example, when a malfunction occurs in the output tray extension mechanism 54, or when force is applied to the output tray extension member 22 after the output tray 7 has been properly stored. The output tray 7 is improperly stored in the media transport device body 2 when the output tray body 21 is positioned in the output tray storage position and the output tray extension member 22 is positioned in an improper shortened position.

[0048] The output tray extension member 22 may remain in the improperly shortened position, as shown in Figure 12, even after the output tray 7 has been improperly stored in the media transport device body 2 and the feed tray body 11 has been placed in the feed tray storage position. Furthermore, after the output tray 7 has been properly stored and the feed tray 6 has been stored in the media transport device body 2, force may be applied to the output tray extension member 22, causing it to be placed in the improperly shortened position, as shown in Figure 12.

[0049] Figure 16 is an enlarged cross-sectional view showing the image reading device 1 when the output tray 7 is improperly stored in the media transport device body 2. The output tray extension member 22 is positioned to overlap the area through which the paper feed tray body 11 passes when opening and closing the paper feed tray body 11 when the output tray 7 is improperly stored in the media transport device body 2. The base end 35 of the paper feed tray body 11 comes into contact with the output tray extension member 22 when the paper feed tray body 11 moves toward the paper feed tray deployed position when the output tray 7 is improperly stored in the media transport device body 2.

[0050] The paper feed tray body 11 is positioned in the middle of the paper feed tray, as shown in Figure 17, when the output tray 7 is improperly stored in the media transport device body 2, by contact between its base end 35 and the output tray extension member 22. Figure 17 is a perspective view of the image reading device 1 when the output tray 7 is improperly stored in the media transport device body 2 and the paper feed tray body 11 is positioned in the middle of the paper feed tray. The middle of the paper feed tray is different from the stored position and different from the unfolded position, representing a position between the stored position and the unfolded position. Contact between the base end 35 and the output tray extension member 22 prevents the paper feed tray body 11 from moving toward the unfolded position and prevents the paper feed tray body 11 from being positioned in the unfolded position. Contact between the base end 35 and the output tray extension member 22 may cause damage to the paper feed tray 6 when the user moves the paper feed tray body 11 toward the paper feed tray extended position, which may also cause damage to the output tray 7.

[0051] The contact ribs 44 of the blind cover 18 come into contact with the tip 27 of the paper output tray extension member 22 as the blind cover 18 moves from the open position to the closed position when the paper output tray 7 is improperly stored in the media transport device body 2. When the blind cover 18 is positioned in the intermediate position, the contact ribs 44 come into contact with the tip 27 of the paper output tray extension member 22, preventing the blind cover 18 from moving towards the closed position, and it ends up in the intermediate position as shown in Figure 13. A gap 46 larger than a predetermined value is formed between the upper end 36 of the blind cover 18 and the base end 35 of the paper feed tray body 11 when the blind cover 18 is positioned in the intermediate position. The image reading device 1 can notify the user that the paper output tray 7 is improperly stored in the media transport device body 2 when the size of the gap 46 between the upper end 36 of the blind cover 18 and the base end 35 of the paper feed tray body 11 becomes larger than a predetermined value.

[0052] The cover closing sensor 56 detects that the cover 18 is not in the closed position because it is positioned in an intermediate position. When the control device 57 detects that the paper feed tray body 11 is in the paper feed tray storage position and that the cover 18 is not in the closed position, it determines that the output tray extension member 22 is not in the output tray shortened position. When the control device 57 determines that the output tray extension member 22 is not in the output tray shortened position, it controls the power lamp 5 to make the power lamp 5 blink. By making the power lamp 5 blink, the image reading device 1 can notify the user that the output tray 7 is improperly stored in the media transport device body 2.

[0053] The image reading device 1 can prevent the user from moving the paper feed tray body 11 toward the paper feed tray deployment position by informing the user that the output tray 7 is improperly stored in the media transport device body 2. The image reading device 1 can prevent damage to the paper feed tray 6 or the output tray 7 by preventing the paper feed tray body 11 from moving toward the paper feed tray deployment position when the output tray 7 is improperly stored in the media transport device body 2.

[0054] When the user is notified that the output tray 7 is improperly stored in the media transport device body 2, the user moves the cover 18 toward the closed position and places the cover 18 in the closed position. As the cover 18 moves toward the closed position, the tip 27 of the output tray extension member 22 is pushed by the contact rib 44 and translates toward the output tray shortened position. As the cover 18 is placed in the closed position, the tip 27 of the output tray extension member 22 is pushed by the contact rib 44 and is placed in the output tray shortened position, as shown in Figure 9. Therefore, the user can easily place the output tray extension member 22 in the output tray shortened position by placing the cover 18 in the closed position without opening the cover 18 or the paper feed tray body 11. In other words, the image reading device 1 can simplify the user's task of placing the output tray extension member 22 in the output tray shortened position when the output tray 7 is improperly stored in the media transport device body 2.

[0055] When the control device 57 detects that the paper feed tray body 11 is in the paper feed tray storage position and that the cover 18 is in the closed position, it determines that the output tray extension member 22 is in the output tray shortened position. When the control device 57 determines that the output tray extension member 22 is in the output tray shortened position, it controls the power lamp 5 so that the power lamp 5 turns off. By turning off the power lamp 5, the image reading device 1 can notify the user that the output tray 7 is properly stored in the media transport device body 2. When the power lamp 5 is off, the user can prevent damage to the paper feed tray 6 or the output tray 7 by moving the paper feed tray body 11 toward the paper feed tray extended position.

[0056] [Effects of the media transport device in the example] The media transport device of this embodiment comprises a media transport device body 2, a paper output tray body 21, a paper output tray extension member 22, a cover 18, and contact ribs 44. The media transport device body 2 has a transport path 33 connecting an insertion port 31 and a discharge port 32. The paper output tray body 21 is rotatably supported by the media transport device body 2 and is positioned in either the paper output tray extended position or the paper output tray retracted position. The paper output tray extension member 22 is translatably supported relative to the paper output tray body 21 and is positioned in either the paper output tray extended position or the paper output tray shortened position. The cover 18 is rotatably supported by the media transport device body 2 and is positioned in either the open or closed position. The contact ribs 44 are fixed to the cover 18. The discharge port 32 is connected to the paper output tray body 21 when the paper output tray body 21 is positioned in the paper output tray extended position. The insertion opening 31 is opened by the cover 18 when the cover 18 is in the open position, and closed by the cover 18 when the cover 18 is in the closed position. The contact rib 44 contacts the paper output tray extension member 22 when the cover 18 moves toward the closed position, provided that the paper output tray body 21 is in the paper output tray storage position and the paper output tray extension member 22 is not in the paper output tray shortened position. The cover 18 is positioned at an intermediate position between the open position and the closed position when the paper output tray 7 is improperly stored and the contact rib 44 contacts the paper output tray extension member 22.

[0057] The media transport device of the embodiment can notify the user whether the output tray extension member 22 is positioned in the output tray shortened position by whether the cover 18 is positioned in the closed position. For example, even if the position where the output tray extension member 22 is positioned is not visible from the outside, the media transport device of the embodiment notifies the user that the output tray extension member 22 is not positioned in the output tray shortened position by positioning the cover 18 in the middle of the cover. By notifying the user that the output tray extension member 22 is not positioned in the output tray shortened position, the media transport device of the embodiment can prompt the user to take action to avoid malfunctions and prevent malfunctions caused by the output tray 7 being improperly stored.

[0058] Furthermore, in the media transport device of the embodiment, when the output tray 7 is improperly stored and the contact rib 44 contacts the output tray extension member 22, the blind cover 18 moves toward the closed position, thereby translating the output tray extension member 22 toward the output tray shortened position. In the media transport device of the embodiment, when the output tray 7 is improperly stored and the contact rib 44 contacts the output tray extension member 22, the blind cover 18 is positioned in the closed position, thereby positioning the output tray extension member 22 toward the output tray shortened position. In the media transport device of the embodiment, when the output tray 7 is improperly stored, the user can position the blind cover 18 in the closed position to position the output tray extension member 22 toward the output tray shortened position, thereby facilitating the user's work.

[0059] Furthermore, the media transport device of the embodiment further includes a paper feed tray body 11 that is rotatably supported by the media transport device body 2 and positioned in either the paper feed tray deployed position or the paper feed tray retracted position. The insertion opening 31 is connected to the paper feed tray body 11 when the paper feed tray body 11 is positioned in the paper feed tray deployed position. When the output tray 7 is improperly stored in the media transport device body 2, the paper feed tray body 11 comes into contact with the output tray extension member 22 as it moves from the paper feed tray retracted position toward the paper feed tray deployed position. In other words, the media transport device of the embodiment experiences a malfunction in which the paper feed tray body 11 is prevented from being positioned in the paper feed tray deployed position when the output tray 7 is improperly stored in the media transport device body 2. The media transport device of the embodiment can notify the user that a malfunction has occurred in which the paper feed tray body 11 is not positioned in the paper feed tray deployed position by notifying the user that the output tray extension member 22 is not positioned in the output tray shortened position.

[0060] Furthermore, the media transport device of the embodiment further includes a cover opening mechanism 52 and a cover closing spring 39. The cover opening mechanism 52 moves the blind cover 18 toward the open position when the paper feed tray body 11 moves toward the paper feed tray unfolded position. The cover closing spring 39 provides elastic force to the blind cover 18 so that the blind cover 18 moves toward the closed position when the paper feed tray body 11 is in the paper feed tray stowed position. In the media transport device of the embodiment, the elastic force of the cover closing spring 39 moves the blind cover 18 toward the closed position, so that the blind cover 18 can be positioned in an intermediate position when the output tray 7 is improperly stored.

[0061] By the way, in the previously described embodiment, the cover closing spring 39 of the media transport device provides elastic force to the blind cover 18 so that the blind cover 18 is positioned in an intermediate position when the output tray 7 is improperly stored. However, a greater elastic force may be provided to the blind cover 18. For example, the cover closing spring 39 provides elastic force to the blind cover 18 so that when the output tray 7 is improperly stored and the feed tray 6 is properly stored, the output tray extension member 22 moves toward the output tray shortened position. In this case, the user can easily position the output tray extension member 22 toward the output tray shortened position without moving the blind cover 18 to the closed position when the output tray 7 is improperly stored. In other words, the media transport device can simplify the user's task of easily positioning the output tray extension member 22 toward the output tray shortened position when the output tray 7 is improperly stored.

[0062] Furthermore, the media transport device of the embodiment further includes a paper feed tray storage sensor 55, a cover closing sensor 56, a power lamp 5, and a control device 57. The paper feed tray storage sensor 55 detects whether the paper feed tray body 11 is in the paper feed tray storage position. The cover closing sensor 56 detects whether the blind cover 18 is in the closed position, thereby detecting whether the output tray extension member 22 is in the output tray shortened position. The control device 57 flashes the power lamp 5 when it is detected that the paper feed tray body 11 is in the paper feed tray storage position and that the output tray extension member 22 is not in the output tray shortened position. The media transport device of the embodiment can notify the user that the output tray extension member 22 is not in the output tray shortened position by flashing the power lamp 5 when the blind cover 18 is not in the closed position.

[0063] Incidentally, the cover closing sensor 56 of the media transport device in the previously described embodiment may be replaced with a paper output tray shortening sensor that directly detects whether or not the paper output tray extension member 22 is positioned in the paper output tray shortened position. Even when a paper output tray shortening sensor is used, the media transport device can notify the user that the paper output tray extension member 22 is not positioned in the paper output tray shortened position by flashing the power lamp 5. Also, the paper output tray 7 may become larger when the paper output tray shortening sensor is located inside the paper output tray body 21. For this reason, the media transport device in the previously described embodiment, by being equipped with a cover closing sensor 56, can have a smaller paper output tray 7 compared to other media transport devices equipped with a paper output tray shortening sensor.

[0064] Incidentally, the media transport device in the previously described embodiment notifies the user that the output tray 7 is improperly stored using the power lamp 5, but the user may also be notified using a notification unit other than the power lamp 5. Examples of such notification units include a display device that shows a message indicating that the output tray 7 is improperly stored, and an audio device that emits a sound indicating that the output tray 7 is improperly stored. A media transport device equipped with such a notification unit can also notify the user that the output tray 7 is improperly stored, similar to the media transport device in the previously described embodiment.

[0065] Incidentally, in the media transport device of the embodiment described above, the user is notified that the output tray 7 is improperly stored using a notification unit exemplified by the power lamp 5, but it is not necessary to notify the user using a notification unit. Even in this case, the media transport device can notify the user that the output tray extension member 22 is not in the output tray shortened position by preventing the cover 18 from being placed in the closed position when the output tray 7 is improperly stored.

[0066] Furthermore, the media transport device of the embodiment further includes a paper output tray extension mechanism 54. The paper output tray extension mechanism 54 translates the paper output tray extension member 22 toward the paper output tray extension position when the paper output tray body 21 moves toward the paper output tray unfolded position. The paper output tray extension mechanism 54 further translates the paper output tray extension member 22 toward the paper output tray shortened position when the paper output tray body 21 moves toward the paper output tray storage position.

[0067] The media transport device of the embodiment does not require the user to perform any work when extending or retracting the paper output tray 7, thus simplifying the user's work. In the media transport device of the embodiment, if a malfunction occurs in the paper output tray extension mechanism 54, the paper output tray extension member 22 may not be placed in the paper output tray shortened position even if the paper output tray body 21 is in the paper output tray storage position, resulting in the paper output tray 7 being improperly stored. The media transport device of the embodiment can notify the user that a malfunction has occurred in the paper output tray extension mechanism 54 when the cover 18 is not placed in the closed position.

[0068] By the way, although the media transport device in the embodiment described above is provided with a paper output tray extension mechanism 54, the paper output tray extension mechanism 54 may be omitted. For example, if the paper output tray extension mechanism 54 is omitted, the user places the paper output tray extension member 22 in the paper output tray shortened position before the paper output tray body 21 moves toward the paper output tray storage position. If the paper output tray extension mechanism 54 is omitted, the user further places the paper output tray extension member 22 in the paper output tray extended position after the paper output tray body 21 has been moved to the paper output tray unfolded position. Even if the paper output tray extension mechanism 54 is omitted, the media transport device can notify the user that the paper output tray extension member 22 is not in the paper output tray shortened position when the cover 18 is not in the closed position.

[0069] Furthermore, the concealing cover 18 of the media transport device in the embodiment includes a cover shell 41 formed to conform to a first plane. The contact ribs 44 are formed in a plate shape conforming to a second plane perpendicular to the first plane and are integrally formed with the cover shell 41. The contact ribs 44 can reinforce the cover shell 41 of the concealing cover 18 so that the cover shell 41 does not bend. The media transport device in the embodiment can reduce the amount of multiple vertical reinforcing ribs 42 and multiple horizontal reinforcing ribs 43 that reinforce the cover shell 41 to prevent bending, thereby reducing manufacturing costs.

[0070] Incidentally, the contact ribs 44 of the media transport device in the previously described embodiment are formed to follow a plane perpendicular to the plane along which the cover shell 41 follows, but they may also be formed to follow a plane intersecting the plane along which the cover shell 41 follows. Even when formed in this way, the contact ribs 44 can reinforce the cover shell 41 so that it does not bend. Furthermore, although the contact ribs 44 of the media transport device in the previously described embodiment are formed to reinforce the cover shell 41, they may also be formed so that the cover shell 41 is not reinforced. For example, the contact ribs 44 may be formed in a columnar shape protruding from the cover shell 41. Even when the contact ribs 44 are formed in this way, the media transport device can notify the user that the paper output tray extension member 22 is not positioned in the paper output tray shortened position, and can prevent malfunctions caused by the improper storage of the paper output tray 7.

[0071] By the way, although the media transport device in the previously described embodiment is used in the image reading device 1, it may also be used in other devices. An example of such a device is a printer that prints characters and figures on a medium. In the printer, the reading unit 38 of the media transport device in the previously described embodiment is replaced with a printing unit that prints characters and figures on the medium transported along the transport path 33. In this case as well, the media transport device can notify the user that the paper output tray extension member 22 is not positioned in the paper output tray shortened position, similar to the media transport device in the previously described embodiment, and can prevent malfunctions caused by the improper storage of the paper output tray 7.

[0072] Although examples have been described above, the examples are not limited to those described above. Furthermore, the components described above include those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that fall within the so-called equivalent range. Moreover, the components described above can be combined as appropriate. Furthermore, at least one of various omissions, substitutions, and modifications of the components can be made without departing from the gist of the examples. [Explanation of symbols]
