According to this aspect, the number of steps required for replacing the cable can be reduced, and the cable can be replaced more easily and in a shorter time.

[0020] The present invention will be specifically described below. The XYZ coordinate system shown in each figure is an orthogonal coordinate system, with the X-axis direction being the width direction of the medium transported inside the device, and also the depth direction of the device. In this embodiment, the -X direction is the front side of the device, and the +X direction is the rear side of the device. The Y-axis direction is the width direction of the device, and when looking at the device from the -X direction, the +Y direction is the left side, and the -Y direction is the right side. The Z-axis direction is the height direction of the device and the vertical direction.

[0021] 1 and 2, a scanner 1, which is an example of an image reading device, includes an upper unit 10 on top of a lower unit 2 configured as a flatbed type scanner. The upper unit 10 is provided so as to be openable and closable relative to the lower unit 2 via a hinge (not shown) provided at the end in the +X direction, and opening the upper unit 10 opens and closes a document table glass 3 (see FIG. 3) that constitutes the upper part of the lower unit 2. The document table glass 3 is an example of a medium placement section on which a medium is placed. The upper unit 10 includes a device main body 11, a feed tray 15, an opening / closing cover 17, a first frame 12, and a discharge tray 47. The base of the device main body 11 is composed of a first frame 12 and a second frame 48, with a front housing 13 provided in the -X direction relative to the first frame 12 and the second frame 48, and a rear housing 14 provided in the +X direction relative to the first frame 12 and the second frame 48.

[0022] The medium before feeding is placed on the feed tray 15. An edge guide 16A that guides the +X direction edge of the medium placed on the feed tray 15 is provided in the +X direction on the feed tray 15, and an edge guide 16B that guides the -X direction edge of the medium placed on the feed tray 15 is provided in the -X direction on the feed tray 15. The edge guides 16A and 16B are provided to be slidable in directions approaching or separating from each other.

[0023] The opening / closing cover 17 is provided so as to be rotatable about a rotation axis (not shown) having an axis center parallel to the X-axis direction. The opening / closing cover 17 is provided with an unlocking lever 18, and the user can unlock the opening / closing cover 17 in the fully closed state by pulling up the unlocking lever 18, thereby opening the opening / closing cover 17. By opening the opening / closing cover 17, the inside of the upper unit 10, in particular the curved reversal path, is exposed, making it possible to clear jams.

[0024] 2, a facing portion 50 is provided on the side of the upper unit 10 facing the lower unit 2. The facing portion 50 will be described later.

[0025] As shown in FIG. 3, the lower unit 2 includes a document table glass 3, and a second reading unit 4 is provided below the document table glass 3 so as to be movable along the Y-axis direction. A pressing mat 52 that presses down the medium placed on the platen glass 3 is provided on the underside of the upper unit 10 (see also FIG. 2). No pressing mat 52 is provided in the +Y direction area in the Y axis direction, and the medium can be transported toward the second reading unit 4 stopped in this area to read the sides of the medium. The upper unit 10 is equipped with a first reading unit 45 inside, and this first reading unit 45 and the second reading unit 4 can read both sides of the transported medium.

[0026] The medium transport path inside the upper unit 10 will be further described below with reference to FIG. 3, the dashed line indicated by the symbol T indicates a curved and inverted path in the upper unit 10. The curved and inverted path T is a path from a separation roller pair 23 to a discharge roller pair 39, which will be described later. The medium placed on the feed tray 15 is sent out by the pick roller 20. The pick roller 20 is provided at a position facing the end area of ​​the medium placed on the feed tray 15 in the +Y direction.

[0027] The pick roller 20, which is driven by a motor (not shown), is supported by a roller support member 21. The roller support member 21 is rotatably provided coaxially with a feed roller 24 (described later), and moves the pick roller 20 forward and backward relative to the medium by rotating. A separation roller pair 23 is provided downstream of the pick roller 20. The separation roller pair 23 is composed of a feed roller 24 driven by a motor (not shown) and a separation roller 25 to which rotational resistance is applied. A rotational resistance is applied to the separation roller 25 by a torque limiter (not shown), and the medium sent out by the pick roller 20 is separated by the action of the separation roller 25 and sent downstream.

[0028] A first roller pair 27 is provided downstream of the separation roller pair 23. The first roller pair 27 is composed of a drive roller 28 driven by a motor (not shown) and a driven roller 29 that can be rotated by the drive roller 28. The medium is curved downward downstream of the first roller pair 27. A second roller pair 31 is provided downstream of the first roller pair 27. In the curve reversal path T, the second roller pair 31 nips and transports the medium at a position where the downward facing surface of the medium changes to an upward facing surface, that is, downstream of the most +Y direction position on the curve reversal path T. The second roller pair 31 is composed of a drive roller 32 driven by a motor (not shown) and a driven roller 33 which is rotatable by the drive roller 32.

[0029] The medium sent out from the feed tray 15 is curved downward by the curved reversal path T, and then reversed in the direction opposite to the direction in which the medium is sent out from the feed tray 15, i.e., in the -Y direction. The reversed medium passes through an area facing the second reading unit 4 stopped at the position shown in Fig. 3, is read, and reaches the third roller pair 35. The third roller pair 35 is composed of a drive roller 36 driven by a motor (not shown), and a driven roller 37 that can be rotated by the drive roller 36.

[0030] The medium sent by the third roller pair 35 passes through an area facing the first reading unit 45, is read, and reaches the discharge roller pair 39. The discharge roller pair 39 is composed of a drive roller 40 driven by a motor (not shown), and a driven roller 41 that can rotate following the drive roller 40. The medium is discharged onto the discharge tray 47 by the discharge roller pair 39. The discharged medium is placed in an inclined state on the inclined portion 47a of the discharge tray 47.

[0031] During the process of the medium being transported along the above-mentioned curved inversion path T, the top surface of the medium placed on the feed tray 15 is read by the second reading unit 4, and the bottom surface of the medium placed on the feed tray 15 is read by the first reading unit 45. In this embodiment, the first reading unit 45 and the second reading unit 4 are both configured by a contact image sensor module (CISM). The CISM constituting the first reading unit 45 and the CISM constituting the second reading unit 4 are arranged such that the orientation in the X-axis direction is inverted by 180° so that the pixel arrangement order in the left-right direction of the reading surface matches. This eliminates the need for image processing to invert the image acquired by either the first reading unit 45 or the second reading unit 4. The pixel arrangement order of the CISM constituting the first reading unit 45 and the CISM constituting the second reading unit 4 may be different. In this case, the scanner 1 may perform processing to rotate one of the images read by the first reading unit 45 or the second reading unit 4 by 180°.

[0032] Next, cable replacement in the upper unit 10 will be described. 1, 2, and 4, the upper unit 10 has a front housing 13 on the front side of the device, and a rear housing 14 on the rear side of the device. The front housing 13 and the rear housing 14 are provided detachably, and by removing them, the -X direction side and +X direction side of the first frame 12 and the second frame 48 that form the base of the upper unit 10 are exposed as shown in FIG.

[0033] The first frame 12 and the second frame 48 form the curved and inverted path T (see FIG. 3) described above, and support each roller provided on the curved and inverted path T. A drive mechanism unit 19 is provided in the +X direction with respect to the first frame 12, and this drive mechanism unit 19 drives each roller provided on the curved reversal path T. The drive mechanism unit 19 is configured to include a motor and gears (not shown).

[0034] The first frame 12 is provided with a first reading unit 45. The first reading unit 45 can be pulled out in the -X direction, i.e., toward the front of the device, by removing the front housing 13 as shown in FIG. 4. Specifically, as shown in FIG. 7, the first reading unit 45 is fixed to the first frame 12 via a plate 66 by screws 65, 65. Therefore, the first reading unit 45 can be pulled out in the -X direction, i.e., toward the front of the device, by removing the screws 65, 65. The pulled out first reading unit 45 can be attached to the first frame 12 by inserting it in the +X direction, i.e., toward the rear of the device, and can be fixed to the first frame 12 by the screws 65, 65.

[0035] A first cable 61 and a second cable 62 are connected to the first reading unit 45. For the first cable 61 and the second cable 62, a flexible flat cable (FFC) is used, for example. One end of the first cable 61 and the second cable 62 is connected to the first reading unit 45 near the end in the -X direction. The other ends of the first cable 61 and the second cable 62 are connected to a circuit board 63 provided at the end in the +X direction as shown in FIG.

[0036] 9 shows the layout of the first cable 61 and the second cable 62 between the first reading unit 45 and the circuit board 63. As shown in FIG. 9, the first cable 61 and the second cable 62 are wired along the Y-axis direction at the end in the -X direction. Reference numeral 61a denotes a section of the first cable 61 wired along the Y-axis direction at the end in the -X direction, and hereinafter this is referred to as the first section 61a of the first cable 61. Similarly, reference numeral 62a denotes a section of the second cable 62 wired along the Y-axis direction at the end in the -X direction, and hereinafter this is referred to as the first section 62a of the second cable 62. The first sections 61a and 62a are wired along the side surfaces of the first frame 12 and the second frame 48 in the -X direction as shown in FIG.

[0037] 9, reference numeral 61b denotes a section of the first cable 61 wired along the X-axis direction, which will hereinafter be referred to as the second section 61b of the first cable 61. Similarly, reference numeral 62b denotes a section of the second cable 62 wired along the X-axis direction, which will hereinafter be referred to as the second section 62b of the second cable 62. The second section 61b and the second section 62b are wired along the X-axis direction below the second frame 48 as shown in FIG.

[0038] 9, reference numeral 61c denotes a section of the first cable 61 that is wired along the Y-axis direction at the end in the +X direction, and hereinafter this is referred to as the third section 61c of the first cable 61. Similarly, reference numeral 62c denotes a section of the second cable 62 that is wired along the Y-axis direction at the end in the +X direction, and hereinafter this is referred to as the third section 62c of the second cable 62. The third section 61c and the third section 62c are routed along the side surface of the second frame 48 in the +X direction as shown in FIG.

[0039] 10, the first cable 61 is connected to the first reading unit 45 at the first sensor connection portion 45a. The second cable 62 is connected to the first reading unit 45 at the second sensor connection portion 45b. The first sensor connection portion 45a and the second sensor connection portion 45b are examples of a first connection portion where one end of the first cable 61 and one end of the second cable 62 are connected to the first reading unit 45, respectively, and are configured by connectors for connecting flexible flat cables in this embodiment.

[0040] 9, the first cable 61 is connected to the circuit board 63 at a first board connection portion 63a. The second cable 62 is connected to the circuit board 63 at a second board connection portion 63b. The first board connection portion 63a and the second board connection portion 63b are examples of second connection portions where the other ends of the first cable 61 and the second cable 62 are connected to the circuit board 63, respectively, and are configured by connectors for connecting flexible flat cables in this embodiment.

[0041] 9, the first sensor connection portion 45a and the second sensor connection portion 45b, which are an example of a first connection portion, and the first substrate connection portion 63a and the second substrate connection portion 63b, which are an example of a second connection portion, are arranged apart from each other in the X-axis direction, that is, in the width direction intersecting with the medium transport direction in the curved inversion path T. As a result, the length of the second sections 61b and 62b in the X-axis direction is longer than the length of the first reading unit 45 in the X-axis direction.

[0042] 2 and 5, a facing portion 50 is provided below the upper unit 10. In this embodiment, the facing portion 50 is composed of a cover member 51 and a pressing mat 52. When the upper unit 10 is closed, the facing portion 50 faces the document table glass 3 of the lower unit 2 as shown in FIG. 3, and presses a medium placed on the document table glass 3 toward the document table glass 3.

[0043] The facing portion 50 is detachably provided in the upper unit 10. More specifically, as shown in Fig. 5, a holding member 53 is provided in the -Y direction with respect to the cover member 51, and the cover member 51 and the holding member 53 are configured to be substantially flush with each other. The cover member 51 and the holding member 53 are provided with a plurality of hook-and-loop fasteners 55. The hook-and-loop fasteners 55 are an example of a fastening means for fastening the pressing mat 52 to the cover member 51 and the holding member 53.

[0044] 5, the cover member 51 and the holding member 53 are exposed. The holding member 53 is fixedly provided to the second frame 48, and the cover member 51 is detachably provided to the second frame 48. The cover member 51 is fixed to the second frame 48 by screws (not shown). By removing this cover member 51, the second section 61b of the first cable 61 and the second section 62b of the second cable 62 are exposed as shown in FIG.

[0045] In the above configuration, when it becomes necessary to replace the first reading unit 45 and the first and second cables 61 and 62, the following procedure is followed. Fig. 12 shows the process of replacing the first reading unit 45 and the first and second cables 61 and 62, particularly the process of removing the first and second cables 61 and 62. First, with the upper unit 10 in the closed state, the front housing 13 and the rear housing 14 are removed as shown in Fig. 4 (step S1). Next, the first and second cables 61 and 62 are removed from the first reading unit 45 (step S2).

[0046] When removing the first cable 61 and the second cable 62 from the first reading unit 45, the screws 65, 65 described with reference to Fig. 7 are removed, and the first reading unit 45 is slightly pulled out in the -X direction. This causes the second sensor connection part 45b shown in Fig. 10 to be exposed to the outside of the first frame 12. Note that the first sensor connection part 45a is always exposed to the outside of the first frame 12.

[0047] Next, the first cable 61 and the second cable 62 are removed from the circuit board 63 (step S3). In the circuit board 63, the first board connection portion 63a and the second board connection portion 63b are always exposed to the outside of the second frame 48, as shown in Fig. 8. Therefore, the first cable 61 can be removed from the first board connection portion 63a, and the second cable 62 can be removed from the second board connection portion 63b, without removing the circuit board 63 from the second frame 48.

[0048] Next, the upper unit 10 is opened (step S4), and then the pressing mat 52 and the cover member 51 are removed in this order (step S5). Then, the first cable 61 and the second cable 62 are removed from the upper unit 10 (step S6). After removing the first cable 61 and the second cable 62, new first cables 61 and second cables 62 are wired, a new first reading unit 45 is inserted, and one ends of the first cable 61 and the second cable 62 are connected to the first reading unit 45, and then the first reading unit 45 is fixed. In addition, the other ends of the first cable 61 and the second cable 62 are connected to the circuit board 63. Incidentally, the upper unit 10 may be opened (step S4) before any of steps S1 to S3.

[0049] As described above, the cable replacement method for the upper unit 10 includes the steps of removing the first cable 61 and the second cable 62 (steps S2, S3), opening the upper unit 10 from a closed state and removing the opposing portion 50 (steps S4, S5), and removing the first cable 61 and the second cable 62 exposed by removing the opposing portion 50 (step S6).

[0050] 11, the first cable 61 is fixed to cable fixing portions 48a, 48b, and 48c formed on the second frame 48 with double-sided tape (not shown). Similarly, the second cable 62 is fixed to cable fixing portions 48d, 48e, and 48f formed on the second frame 48 with double-sided tape (not shown). The double-sided tape is an example of a fixing means for fixing the first cable 61 and the second cable 62 to the second frame 48.

[0051] The cable fixing portions 48a, 48b, 48c, 48d, 48e, and 48f are formed in a space 48h formed on the lower side of the second frame 48. The space 48h is a space formed on the lower side of the discharge tray 47 formed in an inclined shape as shown in Fig. 3, and the first cable 61 and the second cable 62 are wired by effectively utilizing this space.

[0052] As described above, in the upper unit 10, the first cable 61 and the second cable 62 are provided at positions that are exposed when the opposing portion 50 is removed. This makes it possible to reduce the number of steps required to replace the first cable 61 and the second cable 62, and allows the first cable 61 and the second cable 62 to be replaced more easily and in a shorter time. In this embodiment, two cables, the first cable 61 and the second cable 62, are used, but one cable or three or more cables may be used.

[0053] The facing portion 50 also includes a pressing mat 52, which is a pressing member that contacts and presses the medium placed on the document table glass 3 when the upper unit 10 is closed, and a cover member 51 that is exposed when the pressing mat 52 is removed. When the pressing mat 52 is removed and the cover member 51 is attached, the first cable 61 and the second cable 62 are covered by the cover member 51. As a result, even when the user removes the pressing mat 52 to replace it, the first cable 61 and the second cable 62 are covered by the cover member 51, so that it is possible to prevent the user from accidentally touching the first cable 61 and the second cable 62 and causing a malfunction.

[0054] Moreover, the first cable 61 and the second cable 62 are fixed to cable fixing portions 48a, 48b, 48c, 48d, 48e, and 48f provided on the second frame 48 that constitutes the base of the upper unit 10. This makes it difficult for vibrations to occur in the first cable 61 and the second cable 62, and can suppress deterioration of communication quality. In addition, when the first cable 61 and the second cable 62 are fixed, a certain amount of gap is secured between the first cable 61 and the second cable 62 and the cover member 51.

[0055] The X-axis direction, i.e., the width direction intersecting with the curved inversion path T, is aligned with the depth direction of the device, and in the width direction, the first sensor connection portion 45a and the second sensor connection portion 45b, which are an example of a first connection portion, are located on the front side of the device, and the first board connection portion 63a and the second board connection portion 63b, which are an example of a second connection portion, are located on the rear side of the device. This allows the circuit board 63 to be located on the rear side of the device, and prevents the user from accidentally touching the circuit board 63.

[0056] Furthermore, since the first reading unit 45 can be inserted and removed from the front side of the device, the workability when replacing the first reading unit 45 is improved.

[0057] In addition, a wireless communication unit 70 for wireless communication with the outside may be provided in a position exposed by removing the facing portion 50, i.e., in the space 48h of the second frame 48, as shown in FIG. 11. With such a configuration, the wireless communication unit 70 can be accessed more quickly and easily. The wireless communication unit 70 is, for example, a contactless IC card reader. The wireless communication unit 70 can read information on an IC card when a user holds the IC card over the wireless communication unit 70.

[0058] Furthermore, the first cable 61 and the second cable 62 are wired between the inclined portion 47a of the discharge tray 47 and the opposing portion 50, i.e., wired below the inclined portion 47a of the discharge tray 47, thereby preventing the device from becoming larger in height due to the wiring of the first cable 61 and the second cable 62.

[0059] It is also preferable to place a sheet material or plate material having electromagnetic shielding properties inside the above-mentioned cover member 51. This makes it possible to suppress deterioration in the quality of communication using the first cable 61 and the second cable 62.

[0060] Furthermore, the present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the invention described in the claims, and it goes without saying that these modifications are also included in the scope of the present invention.
