[Modes for carrying out the invention]

[0007] Hereinafter, the configuration of the scanner 1 as an image reading apparatus will be described with reference to the drawings. In the following respective figures, three axes orthogonal to each other will be described as the X-axis, the Y-axis, and the Z-axis. The direction along the X-axis is the "X direction", the direction along the Y-axis is the "Y direction", the direction along the Z-axis is the "Z direction", the direction of the arrow is the + direction, and the direction opposite to the + direction is the - direction. Note that viewing from the +Z direction or the -Z direction is also referred to as a plan view or planar. The "Y direction" is the direction in which the document is conveyed from the document insertion port 5 to the document discharge port 6. The "X direction" is the device width direction intersecting the Y direction. The "Z direction" is the direction from the installation surface toward the upper surface 4a.

[0008] First, the configuration of the scanner 1 will be described with reference to FIGS. 1 to 4. Note that the white arrows indicate the conveyance direction of the document.

[0009] As shown in FIGS. 1 and 2, the scanner 1 is a handy type that is easy to carry. The housing of the scanner 1 has a lower housing 3 and an upper housing 4. Note that the entire structure surrounded by the lower housing 3 and the upper housing 4 is referred to as the apparatus main body 2. Also, the housing is also referred to as the apparatus main body 2.

[0010] An operation unit 7 for receiving operation inputs is provided in the +X direction of the upper surface 4a of the apparatus main body 2. The operation unit 7 has a scan button 7A and a panel 7B for displaying various information. The panel 7B is, for example, tiltable, and the angle of the panel 7B can be changed so that it is easy for the user to view (see FIG. 3).

[0011] The document insertion port 5 for inserting a document is formed between a path forming member 9 and a top frame 8. As shown in FIG. 2, the document discharge port 6 is formed between the upper housing 4 and the lower housing 3. A part of a conveyance roller 11 as a document conveyance unit is exposed inside the document discharge port 6.

[0012] As shown in FIG. 3, the document conveyance path T1 is a path for conveying a document and is constituted by a path forming member 9. Above the document conveyance path T1, a top frame 8 and a sensor unit 13 as a reading unit are arranged. Further, the sensor unit 13 is arranged at a position facing the conveyance roller 11. Adjacent to the document conveyance path T1, there is a document discharge path T2. The document conveyance path T1 and the document discharge path T2 are along substantially the horizontal direction.

[0013] Below the path forming member 9, magnets 100 capable of being held by a magnetic body are arranged. Specifically, one magnet 100 is arranged at each of two positions in the +X direction and -X direction below the path forming member 9. One magnet 100A is arranged on the lower housing 三 in the +X direction (see FIG. 1). The other magnet 100B is arranged on the lower housing 3 in the -X direction (see FIG. 1).

[0014] The holding force of the magnet 100 is greater than the weight of the apparatus main body 2. Further, the sensor unit 13 and the conveyance roller 11 are arranged between the operation unit 7 and the magnet 100 in a direction intersecting the installation surface 600 (see FIG. 16A) of the apparatus main body 2. Specifically, the sensor unit 13 overlaps at least a part of the magnet 100 when viewed from the Z direction. <(

[0015] Thus, since the magnet 100 having a holding force greater than the weight of the apparatus main body 2 is arranged on the lower housing 3 inside the scanner 1, that is, at the bottom of the apparatus main body, the scanner 1 can be attached to a place having a magnetic body, for example, the back surface 510 of the desk 500 (see FIG. 12B) or the wall 410 (see FIG. 12A). Therefore, the degree of freedom of the installation location can be improved, and for example, the space on the desk can be effectively utilized for other purposes than the scanner 1.

[0016] Furthermore, since the magnet 100 is located inside the housing, or in other words, inside the main body of the device 2, it is possible to suppress the adhesion of magnetic dust to the magnet 100 compared to the case where the magnet 100 is located outside the main body of the device 2, and thus maintain the magnetic force of the magnet 100.

[0017] As shown in Figure 4, a control unit 12 is provided on the lower side of the path forming member 9. The control unit 12 consists of multiple electronic components mounted on a circuit board and performs various controls on the scanner 1, including document transport, reading, and ejection. The control unit 12 also controls the display method of the panel 7B based on the detection result of the gyro sensor 200, which is attached to the scanner 1 as a detection unit.

[0018] The gyro sensor 200 is positioned below the path forming member 9. The gyro sensor 200 has a sensor element, for example, one using a quartz crystal oscillator. The sensor element has a drive arm that vibrates when a drive signal is applied and a detection arm that vibrates due to the Coriolis force and outputs a signal of a corresponding magnitude. Note that the detection unit is not limited to the gyro sensor 200, but may be an accelerometer or the like.

[0019] As described above, the scanner 1 is equipped with a gyro sensor 200, and depending on the orientation of the device body 2, the panel 7B displays information regarding the attachment and detachment of the inversion member 300 (see Figure 5). Therefore, the user can attach or detach the inversion member 300 according to the display. Thus, problems such as paper jams and document dropping can be suppressed depending on the orientation of the scanner 1.

[0020] The document transport path T1 is the path from the document insertion slot 5 to position Y1. The document discharge path T2 is the path downstream from position Y1.

[0021] The document inserted through the document insertion slot 5 is supported by the path forming member 9 and moves towards the nip position determined by the transport roller 11 and the sensor unit 13. When a user of the scanner 1 inserts a document through the document insertion slot 5, they insert the document while abutting the side edge in the -X direction against the edge guide 9a provided at the -X end of the document. This determines the position of the document in the X-axis direction.

[0022] When a user inserts a document, they can feel the document hitting the nip position when the leading edge of the document reaches the transport roller 11 and the sensor unit 13, or when the leading edge of the document hits the transport roller 11. A document sensor (not shown) is provided upstream of the transport roller 11.

[0023] As shown in Figure 3, a compression spring 17 is provided at the top of the sensor unit 13 to exert a pressing force between it and the upper housing 4. The sensor unit 13 is pressed downward by the compression spring 17. As a result, the glass plate 14 comes into contact with the transport roller 11.

[0024] Position Y1 is the rotational center position of the transport roller 11 in the Y-axis direction. Position Y1 is also the contact center position between the transport roller 11 and the glass plate 14. Position Y2 is the document reading position by the sensor unit 13 in the Y-axis direction. Position Y2 is slightly upstream of position Y1.

[0025] The reading position Y2 is located within the contact area between the transport roller 11 and the glass plate 14, caused by the crushing of the transport roller 11. The scanned document is discharged from the document discharge port 6 toward the rear of the device along the document discharge path T2 by the rotation of the transport roller 11.

[0026] Next, the configuration of the reversal member 300 will be explained with reference to Figures 5 to 9.

[0027] As shown in Figures 5 and 6, the scanner 1 is detachably provided with a reversing member 300 for ejecting the document in the direction in which it was inserted, specifically in the -Y direction.

[0028] Specifically, the reversing member 300 is detachably positioned near the document output port 6. The reversing member 300 contacts the leading edge of the document ejected from the document output port 6 and sends the document in the opposite direction to the ejection direction. The reversing member 300 includes a guide portion 310, a mounting adapter 320, and a support portion 330.

[0029] As shown in Figure 9, the support portion 330 has a shape that extends in the X-axis direction and is provided with shaft portions 331 at both ends in the X-axis direction. As shown in Figures 5 and 6, the mounting adapter 320 has a shape that extends in the X-axis direction and is provided with fitting holes 321 at both ends in the X-axis direction.

[0030] The shaft portion 331 of the support portion 330 is fitted into the fitting hole 321 of the mounting adapter 320, thereby supporting the support portion 330 so that it can rotate in the YZ plane around a rotation axis parallel to the X-axis direction.

[0031] As shown in Figures 5 to 8, the guide portion 310 can be rotated to switch between an open state (see Figures 5 and 7) and a closed state (see Figures 6 and 8).

[0032] As shown in Figure 7, the inverting member 300 in the open position is in contact with the leading edge of the document being ejected from the document output port 6. The document being ejected from the document output port 6 in the +Y direction is guided upward by the guide surface 311 and then guided to invert in the -Y direction.

[0033] Reference numeral T3 indicates the document guide path formed by the reversing member 300. By attaching the reversing member 300 to the device body 2 and opening it, the space required for ejecting documents from the rear of the device body 2 can be reduced, thereby saving installation space for the device body 2.

[0034] In this way, by attaching the reversing member 300, it is possible to prevent scanned documents from being returned to the user's side and to prevent documents from jamming in the document output port 6. Furthermore, when the reversing member 300 is not needed, it can be removed, allowing for efficient use of space.

[0035] Next, the method of using the scanner 1 will be explained with reference to Figures 10, 11A, 11B, 12A, and 12B. In this embodiment, the method of using the scanner 1 when it is not used on a desk but is attached to the underside of the desk 510 (see Figure 12B) and when it is attached to a wall 410 (see Figure 12A) will be explained.

[0036] As shown in Figure 10, step S11 involves attaching the scanner 1. Specifically, the scanner 1 is attached to a metal part on the underside 510 of the desk 500 or a metal part on the wall 410 using the magnets 100 placed on the scanner 1.

[0037] In step S12, it is determined whether the document output port 6 is facing upwards. In other words, the orientation of the scanner 1 is determined. Specifically, the control unit 12 causes a determination unit (not shown) to determine, based on the detection result of the gyro sensor 200, whether the document output port 6 of the scanner 1 is facing upwards, i.e., in the first orientation (see Figure 11A).

[0038] As shown in Figure 11A, if the scanner 1 is mounted on the wall 410 and the document output port 6 is facing upwards, the process proceeds to step S14. If the document output port 6 is not facing upwards, the process proceeds to step S13. "The scanner 1 is mounted on the wall 410" means that the top surface 4a of the scanner 1 is mounted so as to be aligned vertically.

[0039] In step S13, it is determined whether the top surface 4a of the scanner 1 (see Figure 11B) is upside down. In other words, it is determined whether the scanner 1 is attached to the underside 510 of the desk 500. Specifically, the control unit 12 causes a determination unit (not shown) to determine, based on the detection result of the gyro sensor 200, whether the top surface 4a of the scanner 1 is upside down, i.e., in the first orientation.

[0040] As shown in Figure 11B, if the scanner 1 is attached to the underside 510 of the desk 500 and the top surface 4a of the scanner 1 is upside down, the process proceeds to step S14. If the scanner 1 is not attached to the underside 510 of the desk 500, the process proceeds to step S15. "The top surface 4a of the scanner 1 is upside down" means that the top surface 4a of the scanner 1 is positioned downwards.

[0041] In step S14, the control unit 12 displays a message on the panel 7B of the scanner 1 recommending the installation of the reversal member 300. Specifically, since the scanner 1 is in the first position, i.e., mounted on the wall 410 of the locker 400, or mounted on the underside 510 of the desk 500, the control unit 12 informs the user by displaying a message on the panel 7B instructing them to install the reversal member 300 on the scanner 1.

[0042] In step S15, the scanner 1 is left in its original state, that is, without the inversion member 300 attached. In other words, for example, if the scanner 1 is placed on a desk, the inversion member 300 is not attached.

[0043] In step S16, scanning begins. Specifically, the user presses the scan button 7A on scanner 1, and the document is scanned.

[0044] As described above, in the first position, that is, when the scanner 1 is attached to the wall 410 of the locker 400 or to the underside 510 of the desk 500, the reversing member 300 is attached to the scanner 1, thereby preventing the scanned document from being returned to the user's side or the document from getting jammed in the document output port 6.

[0045] As described above, the scanner 1 comprises a sensor unit 13 for reading an image of a document, a transport roller 11 positioned opposite the sensor unit 13 for transporting the document, a housing for housing the sensor unit 13 and the transport roller 11, an operating unit 7 located in the housing and operable by the user, and a magnet 100 capable of holding the device body 2, which includes the sensor unit 13, the transport roller 11, and the housing, in a magnetic material. The sensor unit 13 and the transport roller 11 are positioned between the operating unit 7 and the magnet 100 in a direction intersecting the mounting surface 600 of the device body 2, and the holding force of the magnet 100 is greater than the weight of the device body 2.

[0046] With this configuration, the device body 2 is equipped with a magnet 100 that has a holding force greater than the weight of the device body 2, so the device body 2 can be installed on a magnetic surface, such as the underside 510 of a desk 500 or the wall 410 of a locker 400. This improves the flexibility of the installation location and allows for effective use of the installation surface 600, for example, the top of a desk. It also allows for securing space under the user's feet when using the scanner 1 and enables space saving when storing the scanner 1.

[0047] Furthermore, in the scanner 1 of this embodiment, it is preferable that the magnet 100 is located inside the device body 2. With this configuration, since the magnet 100 is located inside the device body 2, it is possible to suppress the adhesion of magnetic dust to the magnet 100 compared to when the magnet 100 is located outside the device body 2, and the magnetic force of the magnet 100 can be maintained.

[0048] Furthermore, in the scanner 1 of this embodiment, it is preferable to have a document output port 6 for ejecting documents, and a reversing member 300 that is detachably arranged near the document output port 6, contacts the leading edge of the document ejected from the document output port 6, and sends the document in the opposite direction to the direction of ejection. With this configuration, by attaching the reversing member 300, it is possible to prevent scanned documents from being returned to the user's direction or documents from getting jammed in the document output port 6. In addition, when the reversing member 300 is not needed, it can be removed, allowing for effective use of space.

[0049] Furthermore, in the scanner 1 of this embodiment, a gyro sensor 200 for detecting the orientation of the device body 2 and a control unit 12 that performs control based on the detection result of the gyro sensor 200 are included, and it is preferable that the control unit 12 causes the operation unit 7 to display information regarding the attachment and detachment of the inversion member 300 based on the detection result of the gyro sensor 200. With this configuration, since information regarding the attachment and detachment of the inversion member 300 is displayed according to the orientation of the device body 2, the user can attach or detach the inversion member 300 according to the display, and malfunctions caused by the orientation can be suppressed. For example, it can suppress the jamming of documents in the document output port 6 or the dropping of documents.

[0050] Furthermore, in the scanner 1 of this embodiment, the detection unit is preferably a gyro sensor 200. With this configuration, since a gyro sensor 200 is used, the orientation of the device body 2 can be detected with higher precision.

[0051] Furthermore, in the scanner 1 of this embodiment, it is preferable that the control unit 12 displays a message on the operation unit 7 recommending the installation of the inversion member 300 when the gyro sensor 200 determines that the orientation of the device body 2 is a first orientation. With this configuration, the installation of the inversion member 300 is recommended when the device body 2 is in a first orientation, for example, when the document output port 6 is facing upwards or the device body 2 is upside down, thereby preventing documents from jamming in the device body 2 or being sent far away.

[0052] The following describes some variations of the embodiments described above.

[0053] As described above, the magnet 100 is not limited to being placed inside the housing, i.e., inside the main body 2 of the device, but may also be arranged as shown in Figures 13 to 15.

[0054] As shown in Figure 13, the modified scanner 1A has a cover portion 610 that is detachable from the device body 2A. A magnet 100 is placed on the cover portion 610. The magnet 100 can be placed on the outer surface of the device body 2A by sliding and fitting a protrusion on the cover portion 610 into a recess on the device body 2A.

[0055] As shown in Figure 14, the modified scanner 1B has a cover portion 620 that is detachable from the device body 2B. A magnet 100 is placed on the cover portion 620. By fitting the cover portion 620 into a recess provided on the device body 2B, which is the same size as the cover portion 620 in a plan view, the magnet 100 can be placed on the outer surface of the device body 2B.

[0056] As shown in Figure 15, the modified scanner 1C has a magnet 100 that is detachable from the device body 2C. The device body 2C is provided with a recess for housing the magnet 100 and a pin for holding the magnet 100. The magnet 100 is fixed by the elastic pin by sliding it into the recess.

[0057] As shown in Figures 13 and 14, it is preferable that the device has detachable cover parts 610 and 620 attached to the main body 2A and 2B, and that the magnets 100 are located on the cover parts 610 and 620. With this configuration, since the magnets 100 are located on the detachable cover parts 610 and 620, space can be effectively utilized by removing the magnets 100 when they are not needed, for example, when using or storing the device on a desk. Also, when carrying the device, the size and weight can be reduced by removing the magnets 100. In this way, the device can flexibly respond to the needs of the user.

[0058] Furthermore, as shown in Figures 13 and 14, it is preferable that the magnet 100 is placed on the outer surface of the device bodies 2A and 2B. With this configuration, since the magnet 100 is placed on the outer surface of the device bodies 2A and 2B, it is easy to inform the user that it can be attached to a magnetic material.

[0059] As described above, the configuration is not limited to fixing the magnet 100 on the lower housing 3 of the main body of the device 2, but may also be as shown in Figures 16A and 16B. As shown in Figures 16A and 16B, the modified scanner 1D has a moving mechanism 700 that moves the magnet 100 away from the mounting surface 600.

[0060] The moving mechanism 700 has a support portion 710 for supporting the magnet 100 inside the device body 2D, a biasing member 720 for pulling the magnet 100 away from the installation surface 600, and a pressing portion 730 exposed to the outside of the device body 2C. The biasing member 720 is connected to the support portion 710 and the inside of the device body 2C and is biased in the direction of the support portion 710. The pressing portion 730 is in contact with the support portion 710 and a part of it protrudes to the outside of the device body 2C. As shown in Figures 16A and 16B, the support portion 710 is cut out so as to have an inclined surface that slopes downward in the pressing direction in which the pressing portion 730 is pressed. The pressing portion 730 has a contact surface that can contact the inclined surface of the support portion 710.

[0061] As shown in Figure 16A, if the user wants to remove the scanner 1D which is attached to the mounting surface 600 by the magnet 100, the user presses the pressing part 730. When the pressing part 730 is pressed, the inclined surface and the contact surface slide, and as shown in Figure 16B, the support part 710 moves away from the mounting surface 600. In other words, when the pressing part 730 is pressed in the pressing direction, the support part 710 moves in the Z direction. This causes the magnet 100 fixed to the support part 710 to move away from the mounting surface 600, making it easy to remove the scanner 1D from the mounting surface 600. When the pressing part 730 is no longer pressed in the pressing direction, the inclined surface and the contact surface slide, and the support part 710 moves towards the mounting surface 600. This causes the magnet 100 fixed to the support part 710 to move closer to the mounting surface 600, making it possible to attach the scanner 1D to the mounting surface 600.

[0062] As described above, the modified scanner 1D has a moving mechanism 700 that moves the magnet 100 away from the mounting surface 600. The moving mechanism 700 includes a support portion 710 that supports the magnet 100 inside the device body 2C, a biasing member 720 that is connected to the support portion 710 and the device body 2C inside the device body 2C and biased in the direction of the support portion 710, and a pressing portion 730 that contacts the support portion 710 inside the device body 2C and has a portion that protrudes outside the device body 2C. Preferably, when the pressing portion 730 is pressed in the direction of the device body 2C, the magnet 100 moves away from the mounting surface 600. With this configuration, since there is a moving mechanism 700, when the user presses the pressing portion 730, it is possible to separate the magnet 100 from the magnetic mounting surface 600, and the device body 2C can be easily removed from the mounting surface 600.

[0063] As described above, the magnets 100 are not limited to being two in the scanner 1; there may be one or three or more. The sum of the holding forces of the magnets 100 is equal to or greater than the weight of the device body 2C. [Explanation of Symbols]
