[0007] The present invention will be briefly described below. The image reading device of the first aspect comprises a device main body having a reading unit that reads an image of a transported document, and a body support unit that rotatably supports the device main body so that the device main body can assume a plurality of postures, and the device main body has at least one connection unit to which a connection object is connected, and the connection unit is provided on a side surface of the device main body that intersects with the rotation axis direction of the device main body.

[0008] According to this aspect, at least one connection part to which a connection target is connected in the image reading device is provided on a side surface of the device body that intersects with the rotation axis direction of the device body, so that movement of a cable or the like connected to the connection part can be suppressed when the device body is rotated. This makes it difficult for the cable or the like to get in the way when the device body is rotated, and prevents the cable or the like from interfering with the rotation of the device body.

[0009] The second aspect is characterized in that, in the first aspect, when the device main body is in at least one of the plurality of postures, the device main body has a portion where the rotation axis about which the device main body rotates overlaps with the at least one connection portion, as viewed from the direction of the rotation axis. According to this aspect, when viewed from the direction of the rotation axis, the rotation axis of the device body and the at least one connection part overlap each other, so that the rotation center of the device body and the at least one connection part are positioned close to each other, thereby further suppressing movement of the cable or the like connected to the connection part when the device body is rotated.

[0010] A third aspect is characterized in that the first aspect further comprises a motor that is a power source for rotating the device body, and a rotation conversion means that converts the rotation of the motor into rotation of the device body. According to this aspect, by providing a motor that is the power source for rotating the device main body and a rotation conversion means that converts the rotation of the motor into rotation of the device main body, the user does not need to directly rotate the device main body, thereby improving usability for the user.

[0011] The fourth aspect is the third aspect, wherein the motor is provided in the device main body, and the rotation conversion means is a gear rotatably provided in the device main body, the gear rotating by the power of the motor, and a tooth portion fixed to the body support portion, the tooth portion meshing with the gear, the tooth portion being formed on a standing wall portion rising from the body support portion, and having a portion where the standing wall portion and the at least one connecting portion overlap when viewed from the direction of the rotation axis when the device main body is in at least one of the plurality of postures.

[0012] According to this aspect, the vertical wall portion and the at least one connection portion have an overlapping portion when viewed from the direction of the rotation axis, so that the rotation center of the device body and the at least one connection portion are positioned close to each other, thereby further suppressing movement of the cable or the like connected to the connection portion when the device body is rotated.

[0013] The fifth aspect is characterized in that, in the first aspect, the at least one connection portion is located above the axis of rotation when the device body rotates in the vertical direction, regardless of the attitude of the device body. According to this aspect, the at least one connection part is located above the axis of rotation when the device body rotates in the vertical direction, regardless of the posture of the device body. Therefore, when the connection object connected to the connection part is a cable in particular, it is possible to more reliably prevent the cable from coming into contact with the mounting surface of the device and impeding the rotation of the device body when the device body is rotated.

[0014] The sixth aspect is characterized in that, in the fifth aspect, the device has a plurality of connection parts, the plurality of connection parts including a first connection part and a second connection part, and the first connection part and the second connection part are positioned above the rotation axis in the vertical direction regardless of the attitude of the device main body. According to this aspect, the first connection portion and the second connection portion are positioned above the rotation axis in the vertical direction regardless of the attitude of the device main body, and therefore, in a configuration including the first connection portion and the second connection portion, the effect of the fifth aspect described above can be obtained.

[0015] A seventh aspect is characterized in that, in the sixth aspect, the posture of the device main body includes a first posture in which the angle between the reading conveying path facing the reading unit and the mounting surface of the main body support unit is an acute angle, and a second posture in which the angle is smaller than the first posture, the second connection portion is located vertically above the first connection portion regardless of the posture of the device main body, the circuit board having the first connection portion and the second connection portion is arranged on the back side of the device relative to the reading conveying path in a posture in which the board surface is along the reading conveying path or in a posture in which the board surface forms an acute angle with the reading conveying path, and the dimension of the second connection portion in the thickness direction of the circuit board is smaller than the dimension of the first connection portion in the thickness direction.

[0016] According to this aspect, the circuit board is arranged on the rear side of the device relative to the reading conveying path, with the board surface aligned with the reading conveying path or in an upright position so that the board surface forms an acute angle with the reading conveying path.Therefore, assuming the first position of the device main body, the space on the rear side of the reading conveying path decreases as you move upward. In this configuration, the second connection portion, which is located vertically above the first connection portion, has a dimension in the thickness direction of the circuit board that is smaller than the dimension in the thickness direction of the first connection portion, so the first connection portion and the second connection portion are positioned in accordance with the space on the back side of the reading conveying path decreasing upward, and the efficient placement of components can prevent the device from becoming larger. The above-mentioned effects will be described in detail later with reference to the drawings.

[0017] The eighth aspect is characterized in that, in the seventh aspect, the multiple connection portions include a third connection portion that is located vertically below the second connection portion regardless of the posture of the device main body, the first connection portion, the second connection portion, and the third connection portion are provided on the circuit board, and the dimension of the third connection portion in the thickness direction of the circuit board is larger than the dimension of the second connection portion in the thickness direction.

[0018] According to this aspect, the third connection portion, which is located vertically below the second connection portion, has a dimension in the thickness direction of the circuit board that is larger than the dimension in the thickness direction of the second connection portion. Therefore, the third connection portion is positioned in accordance with the increase in the space on the rear side of the reading conveying path toward the bottom, and the efficient placement of components can prevent the device from becoming larger. The above-mentioned effects will be described in detail later with reference to the drawings.

[0019] The 9th aspect is characterized in that, in the 8th aspect, the first connection part is a connection part that complies with USB Type-A, the second connection part is a connection part that complies with USB Type-C, and the third connection part is a connection part for supplying power to the device main body.

[0020] According to this aspect, in a configuration in which the first connection portion is a connection portion conforming to USB Type-A, the second connection portion is a connection portion conforming to USB Type-C, and the third connection portion is a connection portion for supplying power to the device main body, the effects of the above-mentioned eighth aspect can be obtained. Note that USB is an abbreviation for Universal Serial Bus, and Type-A and Type-C are each one of multiple types defined in the USB standard.

[0021] A tenth aspect is characterized in that, in any of the first to ninth aspects, the device main body comprises a transport means for transporting a document and a transport motor for driving the transport means, and the transport motor is provided near the side opposite to the side on which the connection portion is provided.

[0022] According to this aspect, the motor is provided closer to the side opposite to the side on which the connection portion is provided, and therefore, by arranging the motor and the connection portion apart, the size of the device can be prevented from increasing.

[0023] The present invention will be specifically described below. In the following, as an example of an image reading device, a scanner 1 capable of reading at least one of the first side and the opposite second side of a document will be taken as an example. The scanner 1 is a so-called sheet-fed type scanner that reads a document while moving it relative to a reading unit described below. In this specification, the document includes not only a sheet-shaped document but also a card-shaped document and a booklet-shaped document.

[0024] In the XYZ coordinate system shown in each figure, the X axis direction is the width direction of the device and also the width direction of the original, the Y axis direction is the depth direction of the device, and the Z axis direction is the vertical direction. In this embodiment, the +Y direction is the direction from the rear to the front of the device, and the -Y direction is the direction from the front to the rear of the device. Also, the left direction as viewed from the front of the device is the +X direction, and the right direction is the -X direction. In the following description, the direction in which the document is transported may be referred to as "downstream," and the opposite direction may be referred to as "upstream."

[0025] 1 and 2, a scanner 1 includes a device main body 2 and a main body support part 6 that supports the device main body 2 so that it can rotate. The device main body 2 is configured to include a first unit 3, a second unit 4, and a third unit 5. The base of the first unit 3 is formed by a first frame 63 (see FIG. 4). The base of the second unit 4 is formed by a second frame 64 (see FIG. 4). The base of the third unit 5 is formed by a third frame 65 (see FIG. 3).

[0026] 3, the second unit 4 and the third unit 5 are provided rotatably about a frame rotation axis 64a formed on the second frame 64. The frame rotation axis 64a is a rotation axis that forms the rotation axis center parallel to the X-axis direction. The frame rotation shaft 64a fits into a bearing portion 63f formed on the first frame 63. A bearing portion 65a is formed on the third frame 65, and the frame rotation shaft 64a fits into the bearing portion 65a. This allows the second unit 4 and the third unit 5 to rotate integrally with the first unit 3 about the frame rotation axis 64a (see FIG. 4).

[0027] By rotating the second unit 4 and the third unit 5 relative to the first unit 3, it is possible to expose a portion of the document transport path as shown in Fig. 4. In particular, it is possible to expose the document feed path R1 and the reading transport path R2, which will be described later. The second unit 4 is kept closed relative to the first unit 3 by a locking means (not shown), and the user can unlock the locking means by sliding the lock release portion 8a in the -X direction, allowing the second unit 4 to open as shown in Fig. 4.

[0028] The third unit 5 can rotate about a frame rotation axis 64a relative to the first unit 3 and the second unit 4 (see FIG. 3). By rotating the third unit 5 relative to the first unit 3 and the second unit 4, a part of the document transport path can be exposed as shown in FIG. 3. In particular, the reverse transport path R3, which will be described later, can be exposed. The third unit 5 can be kept closed relative to the second unit 4 (see Figures 1 and 2) by a locking means not shown, and the user can open the third unit 5 as shown in Figure 3 by applying an external force to the third unit 5 in the opening direction.

[0029] The device main body 2 is rotatable around a main body rotation axis 6c (see FIGS. 5 to 10) relative to the main body support part 6, and in this embodiment, the device main body 2 can take two postures by rotating. The two postures of the device main body 2 are shown in FIGS. 5 and 6, and hereinafter the posture in FIG. 5 will be referred to as the normal reading posture, and the posture in FIG. 6 will be referred to as the booklet reading posture. The normal reading posture is an example of the first posture of the device main body 2, and the booklet reading posture is an example of the second posture of the device main body 2.

[0030] 5 and 6 are angles formed between a reading conveyance path R2 (described later) and the device's placement surface G. The angle α2 in the booklet reading position is smaller than the angle α1 in the normal reading position. In the normal reading position, the projection area of ​​the device body 2 onto the placement surface G on which the scanner 1 is placed is the smallest, that is, the footprint of the device body 2 is the smallest. In this specification, the footprint refers to the area occupied by the device body 2 in the XY plane when the device body 2 is viewed from above. The normal reading position is suitable for reading sheet-like documents, i.e., documents that have low rigidity and are easily bent, while the booklet reading position is suitable for reading documents that have high rigidity and are not easily bent, such as plastic cards or booklets.

[0031] An operation unit 7 consisting of a number of operation buttons including a power button is provided on the front of the device. Among the side surfaces that form the periphery of the device, a side surface 2a in the +X direction is provided with a first connecting portion 71, a second connecting portion 72, and a third connecting portion 73, as shown in FIG. In this embodiment, each connection portion is a connection portion to which any one of a USB Type-A plug, a USB Type-B plug, a USB Type-C plug, and a power plug is connected. Note that USB is an abbreviation for Universal Serial Bus, and Type-A, Type-B, and Type-C are each one of several types defined in the USB standard.

[0032] In this embodiment, the first connection portion 71 is a portion to which a USB Type-A plug is connected. External devices such as a computer (not shown) or a card reader (not shown) can be connected to the first connection portion 71 via a USB cable (not shown), and a storage medium, for example, a USB memory 400 as shown in FIG. 12, can also be connected. The control portion (not shown) of the device can then save read data in the USB memory 400 connected to the first connection portion 71.

[0033] In this embodiment, the second connection portion 72 is a portion to which a USB Type-C plug is connected. A USB Type-C plug 201 provided at one end of a USB cable 200 can be connected to the second connection portion 72 as shown in Fig. 12 , and an external device (not shown) can be connected via the USB cable 200. In this embodiment, the device main body 2 is configured so that it can also receive power from an external device connected to the second connection portion 72. The diameter of the USB cable 200 is smaller than the diameter of the power cable 300 (described later), which makes the USB cable 200 more flexible than the power cable 300.

[0034] In this embodiment, the third connection part 73 is a part to which a DC jack for supplying power to the apparatus main body 2 is connected. A DC jack 301 provided at one end of a power cable 300 can be connected to the third connection part 73, as shown in FIG. The first connection portion 71, the second connection portion 72, and the third connection portion 73 are mounted on a circuit board 79 (see Figures 7 and 11) located on the rear side of the device, and are arranged so as to be exposed on the side surface 2a of the device main body 2 in the +X direction, as shown in Figure 2.

[0035] In this specification, the connection object connected to the connection part is used in a broad sense to include not only a plug, which is a part directly connected to the connection part, but also a cable to which the plug is attached and a component part including the plug. For example, the USB Type-A plug (not shown) provided on the USB memory 400 shown in Fig. 12 is an example of a connection object connected to the first connection part 71, and the main body of the USB memory 400 is also a connection object connected to the first connection part 71 via a USB Type-A plug (not shown). The plug 201 is an example of a connection object that is connected to the second connection unit 72, and the USB cable 200 is also an example of a connection object that is connected to the second connection unit 72 via the plug 201. DC jack 301 is an example of a connection target that is connected to third connection portion 73, and power cable 300 is also an example of a connection target that is connected to third connection portion 73 via DC jack 301.

[0036] Next, the configuration of the document transport path in scanner 1 will be described with reference to Figures 5 and 6. The document to be fed is supported in an inclined position by document support section 11. Symbol P indicates the supported document. When multiple documents are supported on document support section 11, the top document is sent downstream by feed roller 14. Document support section 11 is formed in upper opening / closing section 10. Upper opening / closing section 10 is rotatable around a rotation axis (not shown), and opens and closes feed port 13 by rotating. Figure 1 shows the upper opening / closing section 10 in a closed state, and Figure 2 shows the upper opening / closing section 10 in an open state. Upper opening / closing section 10 constitutes first unit 3.

[0037] As shown in Fig. 3, the document support section 11 is provided with a pair of edge guides 12a, 12b that guide the side edges of the document. The pair of edge guides 12a, 12b are provided so as to be slidable in the document width direction (X-axis direction). The pair of edge guides 12a, 12b are provided so as to be interlocked by a rack and pinion mechanism (not shown) so as to move away from or towards each other across the center position in the document width direction. In other words, the scanner 1 employs a so-called center feeding system.

[0038] Returning to Figures 5 and 6, the feed roller 14 is provided in the second unit 4. The feed roller 14 receives power from a transport motor 50, which will be described later, and rotates. A separation roller 15 is provided in the first unit 3 at a position opposite the feed roller 14. A rotational torque is applied to the separation roller 15 by a torque limiter (not shown), which prevents double feeding of documents. The feed roller 14 and the separation roller 15 are provided at the center position in the document width direction (see FIG. 4). Instead of the separation roller 15, a separation pad may be provided. In addition, in this embodiment, the feed roller 14 is provided above the documents placed on the document support section 11, and the top document is fed first, but the feed roller 14 may be provided below the documents placed on the document support section 11, and the bottom document is fed first.

[0039] A first pair of transport rollers 16, which is an example of a transport means for transporting the document, is provided downstream of the feed roller 14 and the separation roller 15. The first pair of transport rollers 16 is composed of a first lower roller 17 provided in the first unit 3 and a first upper roller 18 provided in the second unit 4. The first upper roller 18 is provided so as to be able to move toward and away from the first lower roller 17, and is pressed against the first lower roller 17 by a pressing member (not shown), such as a coil spring. Both the first lower roller 17 and the first upper roller 18 rotate by receiving power from a transport motor 50, which will be described later. Two first lower rollers 17 and two first upper rollers 18 are provided, one on each side of the center position in the document width direction (see FIG. 4). When the second unit 4 is closed relative to the first unit 3, the first lower roller 17 and the first upper roller 18 come into contact with each other. When the second unit 4 is opened relative to the first unit 3, the first upper roller 18 moves away from the first lower roller 17.

[0040] A first reading unit 32 and a second reading unit 33 are disposed facing each other downstream of the first transport roller pair 16. The first reading unit 32 is provided in the first unit 3, and the second reading unit 33 is provided in the second unit 4. The first reading unit 32 reads the bottom surface (first side) of the document supported by the document support unit 11, and the second reading unit 33 reads the top surface (second side) of the document supported by the document support unit 11. The second reading unit 33 is provided so as to be able to advance and retreat relative to the first reading unit 32, and is pressed toward the first reading unit 32 by a pressing member (not shown), for example, a coil spring. In this embodiment, the first reading unit 32 and the second reading unit 33 are configured by a contact image sensor module (CISM). Reference numeral 32a denotes a contact glass that configures the first reading unit 32, and reference numeral 33a denotes a contact glass that configures the second reading unit 33.

[0041] A second transport roller pair 20, which is an example of a transport means for transporting a document, is provided downstream of the first reading unit 32 and the second reading unit 33. The second transport roller pair 20 is composed of a second lower roller 21 provided in the first unit 3 and a second upper roller 22 provided in the second unit 4. The second upper roller 22 is provided so as to be able to move forward and backward relative to the second lower roller 21, and is pressed against the second lower roller 21 by a pressing member (not shown), for example a coil spring. Both the second lower roller 21 and the second upper roller 22 rotate by receiving power from a transport motor 50, which will be described later. Two second lower rollers 21 and two second upper rollers 22 are provided, one on each side of the center position in the document width direction (see FIG. 4). When the second unit 4 is closed relative to the first unit 3, the second lower roller 21 and the second upper roller 22 come into contact with each other. When the second unit 4 is opened relative to the first unit 3, the second upper roller 22 moves away from the second lower roller 21.

[0042] 5 and 6, the dashed line indicated by the symbol R1 is the document feed path, and the document feed path R1 extends from the nip position between the feed roller 14 and the separation roller 15 to the nip position of the first transport roller pair 16. In addition, the dashed line indicated by the symbol R2 in Figures 5 and 6 is the reading transport path, and the reading transport path R2 extends from the nip position of the first transport roller pair 16 to the nip position of the second transport roller pair 20. The reading transport path R2 is a document transport path that faces the first reading unit 32 and the second reading unit 33.

[0043] When the device main body 2 is in the normal reading position shown in Fig. 5, a reverse conveyance path R3 is formed downstream of the reading conveyance path R2, along which the scanned document is reversed upward and discharged. The reverse conveyance path R3 is a document conveyance path downstream of the nip position of the second conveyance roller pair 20, and is a document conveyance path that curves and reverses a document conveyed diagonally downward as shown by the two-dot chain line in Fig. 5, and discharges the document diagonally upward from the first discharge opening 37. When the device main body 2 is in the booklet reading position shown in Fig. 6, a non-reversing conveyance path R4 is formed downstream of the reading conveyance path R2, along which the read document is discharged without being reversed. The non-reversing conveyance path R4 is a document conveyance path downstream of the nip position of the second conveyance roller pair 20, and is a document conveyance path for discharging the document, which is conveyed diagonally downward on the reading conveyance path R2 as shown by the two-dot chain line in Fig. 6, diagonally downward from the second discharge opening 38 without being curved or reversed. The second transport roller pair 20 functions as a discharge roller pair that discharges the document from the non-reverse transport path R4.

[0044] Switching between the reversing conveyance path R3 and the non-reversing conveyance path R4 is performed by a flap 35, which serves as a flap member constituting conveyance path switching means. The flap 35 is rotatable around a flap rotation axis 35a, and by rotating, connects the reversing conveyance path R3 to the reading conveyance path R2, or connects the non-reversing conveyance path R4 to the reading conveyance path R2. Connecting the reversing conveyance path R3 to the reading conveyance path R2 means making the reversing conveyance path R3 available, and making the non-reversing conveyance path R4 unavailable. Similarly, connecting the non-reversing conveyance path R4 to the reading conveyance path R2 means making the non-reversing conveyance path R4 available, and making the reversing conveyance path R3 unavailable.

[0045] In this embodiment, the flap 35 is configured to rotate in conjunction with the change in the position of the device main body 2. In this embodiment, a solenoid (not shown) is used as a configuration for rotating the flap 35 in conjunction with the change in the position of the device main body 2. A control unit (not shown) that performs various controls detects the position of the device main body 2 based on a detection signal from a first position detection sensor 87 or a second position detection sensor (not shown), which will be described later, and drives the solenoid based on that detection signal to rotate the flap 35. Note that the means for rotating the flap 35 is not limited to a solenoid, and other actuators such as a motor may also be used. Alternatively, the flap 35 may be configured to rotate mechanically in conjunction with the position of the device main body 2.

[0046] A third conveying roller pair 24 and a fourth conveying roller pair 28 are provided on the reverse conveying path R3. The third transport roller pair 24 is composed of a third drive roller 25 provided in the third unit 5 and a third driven roller 26 provided in the second unit 4. The third driven roller 26 is provided so as to be able to move toward and away from the third drive roller 25, and is pressed toward the third drive roller 25 by a pressing member (not shown), such as a coil spring. The third drive roller 25 is driven by the transport motor 50. The third driven roller 26 is a roller that is rotated by the conveyance motor 50.

[0047] The fourth transport roller pair 28 is composed of a fourth drive roller 29 provided in the third unit 5 and a fourth driven roller 30 provided in the second unit 4. The fourth driven roller 30 is provided so as to be able to move toward and away from the fourth drive roller 29, and is pressed toward the fourth drive roller 29 by a pressing member (not shown), such as a coil spring. The fourth drive roller 29 is driven by the transport motor 50. The fourth driven roller 30 is a roller that is rotated by the conveyor motor 50.

[0048] The third drive roller 25, the third driven roller 26, the fourth drive roller 29, and the fourth driven roller 30 are each provided in pairs so as to sandwich the central position in the document width direction (see FIG. 3). When the third unit 5 is closed relative to the second unit 4, the third drive roller 25 and the third driven roller 26 come into contact, and the fourth drive roller 29 and the fourth driven roller 30 also come into contact. When the third unit 5 is opened relative to the second unit 4, the third drive roller 25 and the third driven roller 26 move apart, and the fourth drive roller 29 and the fourth driven roller 30 also move apart.

[0049] The document conveyed on the reverse conveying path R3 is discharged obliquely upward including a −Y direction component by the fourth conveying roller pair 28, and is supported in an inclined posture by the upper surface 4a of the second unit 4.

[0050] Next, a configuration for rotating the device main body 2 will be described. In this embodiment, the device main body 2 rotates and switches its position using the power of a position switching motor 40 (see FIGS. 7 to 10) under the control of a control unit (not shown). The control unit (not shown) switches the position of the device main body 2 based on a document reading instruction received from an external device (not shown), such as a computer. The external device can set the type of document to be read, and if the type of document to be read is a card-shaped document or a booklet-shaped document, the position of the device main body 2 is set to the booklet reading position, and if the type of document to be read is a sheet-shaped document, the position of the device main body 2 is set to the normal reading position.

[0051] Figure 7 shows the device with the rear cover 66 (see Figure 2) removed, which forms the exterior of the rear side. Reference numeral 41 denotes a rotation conversion means that converts the rotation of the attitude-changing motor 40 into the rotation of the device main body 2. The attitude-changing motor 40 and the rotation conversion means 41 are provided closer to the side in the -X direction in the device width direction. "More towards the side in the -X direction in the device width direction" means being located in the -X direction relative to the center position of the device in the X-axis direction.

[0052] The first frame 63 constituting the base of the first unit 3 is provided with two supported portions 63b spaced apart in the X-axis direction. The main body support portion 6 is provided with two main body rotation shafts 6c spaced apart in the X-axis direction. The first frame 63, i.e., the device main body 2, is rotatable about the main body rotation shaft 6c, as the main body rotation shaft 6c passes through the supported portions 63b. The main body rotation shaft 6c is a rotation shaft whose center is parallel to the X-axis direction.

[0053] The attitude switching motor 40 is provided on the first frame 63. The attitude switching motor 40 is provided on the rear side of the first frame 63 that is provided in an inclined attitude. In Figure 8, the rotation conversion means 41 is a gear rotatably arranged in the first unit 3, and has a gear 47b that rotates by the power of the posture switching motor 40, and a toothed portion 6b that is fixed to the main body support portion 6 and meshes with the gear 47b. The toothed portion 6b is a toothed portion formed around the main body rotation axis 6c on the standing wall portion 6a. The standing wall portion 6a is a member that constitutes the main body support portion 6.

[0054] More specifically, a worm gear 42 is provided on the rotation shaft of the attitude-switching motor 40, and power is transmitted from the worm gear 42 to a gear 43. The gear 43 is configured integrally with a gear 45 via a shaft 44. The gear 45 transmits power to a first compound gear 46, and the first compound gear 46 transmits power to a second compound gear 47. The gear 47b forms a part of the second compound gear 47.

[0055] The posture-changing motor 40 and the components of the rotation conversion means 41 described above, excluding the tooth portion 6b, are provided in the first unit 3, i.e., the device main body 2. Therefore, when the gear 47b is rotated by the power of the posture-changing motor 40, the device main body 2 rotates and the posture is switched as shown by the change from Figure 9 to Figure 10 or the change from Figure 10 to Figure 9. In this embodiment, the posture switching motor 40 and the components of the rotation conversion means 41 described above, excluding the tooth portion 6b, are provided in the first unit 3, i.e., the device main body 2, and the tooth portion 6b is provided in the device main body support portion 6. However, instead of this, the posture switching motor 40 and the components of the rotation conversion means 41 described above, excluding the tooth portion 6b, may be provided in the device main body support portion 6, and the tooth portion 6b may be provided in the device main body 2.

[0056] The upright wall portion 6a is formed with a first contact portion 6e serving as a first rotation restricting means and a second contact portion 6f serving as a second rotation restricting means. A boss 63a provided on the first frame 63 fits between the first contact portion 6e and the second contact portion 6f. When the device body 2 rotates from the booklet reading position shown in FIG. 10 to the normal reading position shown in FIG. 9, the boss 63a comes into contact with the first contact portion 6e, thereby defining the normal reading position of the device body 2. When the device body 2 rotates from the normal reading position shown in FIG. 9 to the booklet reading position shown in FIG. 10, the boss 63a comes into contact with the second contact portion 6f, thereby defining the booklet reading position of the device body 2.

[0057] When the boss 63a abuts against the first abutment portion 6e, or when the boss 63a abuts against the second abutment portion 6f, the drive current value of the position-changing motor 40 increases. Therefore, the control unit (not shown) can detect the position of the device main body 2 based on the rotation direction of the position-changing motor 40 and the increase in the drive current value. However, in this embodiment, a first position detection sensor 87 and a second position detection sensor (not shown), which will be described later, are provided, and the control unit 80 can also detect the position of the device main body 2 based on the detection signals of these sensors. The normal reading position and the booklet reading position of the device main body 2 are maintained by supplying power to the stopped position switching motor 40 and putting it into a hold state.

[0058] The first position detection sensor 87 is an optical sensor and is provided on the first frame 63, i.e., the device main body 2. When the device main body 2 is in the normal reading position, as shown in Fig. 8, a protrusion 6d provided on the main body support part 6 blocks the optical axis of the first position detection sensor 87. When the device main body 2 rotates from this state toward the booklet reading position, the protrusion 6d moves out of the optical axis of the first position detection sensor 87. The second posture detection sensor is not shown in the figure, but like the first posture detection sensor 87, it is an optical sensor that detects a detection portion (not shown) provided on the flap 35 when the device main body 2 switches to the booklet reading posture.

[0059] In the above-described embodiment, the posture of the device main body 2 is switched by the power of the posture switching motor 40, but instead of this, or in addition to this, the posture of the device main body 2 may be switched by the user applying force to the device main body 2.

[0060] 8, reference numeral 90 denotes a second rotation detection unit 90. The second rotation detection unit 90 is a rotary encoder equipped with a detection unit 89b and a rotating disk 90a provided on the rotation shaft 40a of the attitude-changing motor 40. The control unit (not shown) can ascertain the rotation direction and rotation amount of the attitude-changing motor 40 by detecting the rotation amount of the attitude-changing motor 40 using the second rotation detection unit 90.

[0061] As described above, the scanner 1 comprises a main body support part 6 that is placed on the device's placement surface G, and a device main body 2 that is supported by the main body support part 6. The device main body 2 comprises a document transport path for transporting documents, which is a reading transport path R2 that faces the first reading unit 32 and second reading unit 33 that read the documents, a reversing transport path R3 that is a document transport path downstream of the reading transport path R2 and through which the scanned document is turned upside down and discharged, and a non-reversing transport path R4 that is a document transport path downstream of the reading transport path R2 and through which the scanned document is discharged without being reversed. The device main body 2 also comprises a flap 35 that switches the document transport path connected to the reading transport path R2 between the reversing transport path R3 and the non-reversing transport path R4. The device main body 2 is rotatably attached to the main body support part 6, and can be switched by rotation between a first position, which is a normal reading position (FIG. 5), and a second position, which is a booklet reading position (FIG. 6), in which the angle that the reading conveying path R2 forms with the placement surface G is smaller than that of the normal reading position. The flap 35 connects the reading conveying path R2 to the reversing conveying path R3 when the device main body 2 is in the normal reading position, and connects the reading conveying path R2 to the non-reversing conveying path R4 when the device main body 2 is in the booklet reading position.

[0062] By using the non-reversing conveying path R4, the scanner 1 can effectively convey documents that are difficult to bend. Examples of documents that are difficult to bend include booklets and cards. The flap 35 connects the reading conveying path R2 to the reversing conveying path R3 when the device body 2 is in the normal reading position, and connects the reading conveying path R2 to the non-reversing conveying path R4 when the device body 2 is in the booklet reading position. This allows the document to be discharged in a direction along the loading surface G, compared to when the document is discharged using the non-reversing conveying path R4 in the normal reading position. As a result, larger documents can be discharged compared to when the document is discharged using the non-reversing conveying path R4 in the normal reading position. Furthermore, by placing the device main body 2 in the normal reading position, the angle formed between the reading transport path R2 and the placement surface G can be made larger than in the booklet reading position, and the footprint of the device main body 2 can be reduced.

[0063] Next, the arrangement of the connection parts provided on the side surface of the device will be described with reference to FIG. 2 and FIGS. As described above, the device body 2 is rotatably supported by the body support part 6, and can assume multiple positions by rotating. The device body 2 has at least one connection part to which a connection object is connected. In this embodiment, multiple connection parts are provided, and the multiple connection parts are composed of a first connection part 71, a second connection part 72, and a third connection part 73, as shown in FIG. 2. These connection parts are provided on a side surface 2a of the device body 2 that intersects with the rotation axis direction (X-axis direction) of the device body 2. The side surface 2a is the side surface of the device body 2 in the +X direction. Arranging each connection part in this manner makes it possible to suppress movement of the connection objects connected to each connection part when rotating the device body 2. This makes it less likely that the connection objects will get in the way when rotating the device body 2, and prevents the connection objects from interfering with the rotation of the device body 2. In this embodiment, the connection parts are provided on the side surface in the +X direction of the device body 2, but they may also be provided on the side surface in the -X direction.Alternatively, at least one connection part may be provided on the side surface in the -X direction, and at least one other connection part may be provided on the side surface in the +X direction.

[0064] 9 and 10, when the device main body 2 is in at least one of the multiple postures, the device main body 2 has a portion where the main body rotation shaft 6c, which is the rotation axis about which the device main body 2 rotates, overlaps with at least one connection portion. Specifically, in this embodiment, the device main body 2 has a portion where the main body rotation shaft 6c overlaps with the third connection portion 73 in both the normal reading posture and the booklet reading posture. The range indicated by reference symbol Z1 in FIG. 9 and the range indicated by reference symbol Z2 in FIG. 10 are the ranges in the Z axis direction where the main body rotation shaft 6c and the third connection portion 73 overlap. The range indicated by reference symbol Y1 in FIG. 9 and the range indicated by reference symbol Y2 in FIG. 10 are the ranges in the Y axis direction where the main body rotation shaft 6c and the third connection portion 73 overlap. With this configuration, the rotation center of the device body 2 and the third connection part 73 are positioned closer to each other, and movement of the DC jack 301 and the power cable 300 can be further suppressed when the device body 2 is rotated.

[0065] In this embodiment, the main body rotation shaft 6c and the third connection portion 73 overlap in both the normal reading position and the booklet reading position, but the main body rotation shaft 6c and the third connection portion 73 may also be configured to overlap in either the normal reading position or the booklet reading position. In addition, in this embodiment, when viewed from the X-axis direction, the third connection portion 73, excluding the area 73a where the DC jack 301 is fitted, overlaps with the main body rotation axis 6c, but the area 73a where the DC jack 301 is fitted may also overlap with the main body rotation axis 6c. Furthermore, another connection part may overlap the main body rotation shaft 6c instead of the third connection part 73. For example, the second connection part 72, which can receive power from an external device, may overlap the main body rotation shaft 6c.

[0066] In addition, this embodiment is equipped with a posture switching motor 40, which is the power source for rotating the device main body 2, and a rotation conversion means 41 that converts the rotation of the posture switching motor 40 into the rotation of the device main body 2, so the user does not need to directly rotate the device main body 2, improving usability for the user.

[0067] 9 and 10, the rotation conversion means 41 is a gear rotatably provided in the device body 2, and includes a gear 47a that rotates by the power of the position-switching motor 40, and a toothed portion 6b that is fixed to the device support portion 6 and meshes with the gear 47a. The toothed portion 6b is formed on a standing wall portion 6a that rises from the device support portion 6, and has a portion where the standing wall portion 6a and the third connection portion 73 overlap as viewed in the X-axis direction when the device body 2 is in at least one of a plurality of positions. In this embodiment, the standing wall portion 6a and the third connection portion 73 overlap as viewed in the X-axis direction in both the normal reading position (FIG. 9) and the booklet reading position (FIG. 10). The range indicated by the symbol Z3 in Fig. 9 and the range indicated by the symbol Z4 in Fig. 10 are ranges in the Z-axis direction of the portion where the standing wall portion 6a and the third connecting portion 73 overlap. The range indicated by the symbol Y3 in Fig. 9 and the range indicated by the symbol Y4 in Fig. 10 are ranges in the Y-axis direction of the portion where the standing wall portion 6a and the third connecting portion 73 overlap.

[0068] This brings the rotation center of the device body 2 closer to the third connection part 73, further suppressing movement of the DC jack 301 and the power cable 300 when the device body 2 is rotated. In this embodiment, the standing wall portion 6a and the third connection portion 73 overlap when viewed from the X-axis direction in both the normal reading position and the booklet reading position, but the standing wall portion 6a and the third connection portion 73 may also overlap when viewed from the X-axis direction in either the normal reading position or the booklet reading position. Moreover, instead of the third connecting portion 73, another connecting portion may overlap with the standing wall portion 6a when viewed from the X-axis direction.

[0069] Furthermore, at least one connection portion is located above the main body rotation axis 6c in the vertical direction, regardless of the attitude of the device main body 2. Specifically, in this embodiment, the first connection portion 71 and the second connection portion 72 are located above the main body rotation axis 6c in the vertical direction, regardless of the attitude of the device main body 2. This makes it possible to more reliably prevent the cable from coming into contact with the device's mounting surface G and impeding the rotation of the device main body 2 when the device main body 2 is rotated, particularly when the connection object connected to the connection part located above the main body rotation axis 6c in the vertical direction is a cable.

[0070] The postures of the device main body 2 include a normal reading posture in which the angle formed by the reading transport path R2 and the placement surface G of the main body support unit 6 is an acute angle, and a booklet reading posture in which the angle is smaller than that of the normal reading posture. The second connection portion 72 is located vertically above the first connection portion 71 regardless of the posture of the device main body 2. The circuit board 79 including the first connection portion 71 and the second connection portion 72 is provided on the rear side of the device with respect to the reading transport path R2, in an upright posture so that the board surface 79a forms an acute angle with the reading transport path R2, as shown in FIG. 13. The dimension of the second connection portion 72 in the thickness direction of the circuit board (the X-axis direction in the state of FIG. 13) is smaller than the dimension of the first connection portion 71 in the thickness direction.

[0071] This provides the following advantageous effects: In other words, in Fig. 13, the space behind the reading transport path R2 decreases upward in the vertical direction. In this configuration, the second connection portion 72, which is located vertically above the first connection portion 71, has a dimension in the thickness direction of the circuit board 79 that is smaller than the dimension in the thickness direction of the first connection portion 71.Therefore, the first connection portion 71 and the second connection portion 72 are positioned in accordance with the space on the back side of the reading conveying path R2 decreasing upward, and the efficient placement of components can prevent the device from becoming larger. The device body 2 may include a plurality of circuit boards, and each connection section may be provided on a different circuit board.

[0072] The multiple connection parts provided on the scanner 1 include a third connection part 73 that is located vertically below the second connection part 72 regardless of the attitude of the device body 2, and the first connection part 71, the second connection part 72, and the third connection part 73 are provided on a circuit board 79. As shown in Fig. 13, the dimension of the third connection part 73 in the thickness direction of the circuit board 79 is larger than the dimension of the second connection part 72 in the thickness direction. This provides the following advantageous effects. In other words, in Fig. 13, the space behind the reading conveyance path R2 increases downward in the vertical direction. The third connector 73 is positioned in accordance with the downward increase in the space behind the reading conveyance path R2, and the efficient placement of components helps prevent the device from becoming larger.

[0073] In this embodiment, the first connection part 71 is a connection part that complies with USB Type-A, the second connection part 72 is a connection part that complies with USB Type-C, and the third connection part 73 is a connection part for supplying power to the device main body 2. However, it goes without saying that each connection section is not limited to the above embodiment and can be modified as appropriate. For example, the USB standard includes USB Type-B, and any of the above connection sections may be a connection section that complies with USB Type-B. Also, multiple identical connection sections that comply with any of the USB standards may be provided. For example, two connection sections that comply with USB Type-C may be provided. Note that the connection section of this embodiment may further be provided with a connection section that complies with USB Type-B. Furthermore, it is not necessary to provide a connection section conforming to USB Type-A, and it may be configured to provide only a connection section for supplying power to the device main body 2 and a connection section conforming to USB Type-C.

[0074] The device body 2 also includes a first transport roller pair 16 and a second transport roller pair 20 that transport the document, and a transport motor 50 that drives these transport roller pairs, and the transport motor 50 is provided closer to the side surface (side surface 2b) in the -X direction, opposite the side surface (side surface 2a) in the +X direction where the above-mentioned connection portions are provided (see FIG. 7). Providing the transport motor 50 closer to the side surface in the -X direction means that the transport motor 50 is provided in an area in the -X direction with respect to the center position Xc in the X-axis direction of the device body 2. With this configuration, the conveyance motor 50 and the above-mentioned connection parts are arranged apart from each other, which makes it possible to prevent the device from becoming too large.

[0075] 7, reference numeral 51 denotes a drive pulley provided on the drive shaft of the conveyance motor 50, reference numeral 53 denotes a driven pulley, and reference numeral 52 denotes a belt wound around the drive pulley 51 and the driven pulley 53. The driving force of the conveyance motor 50 is transmitted from the driven pulley 53 to each roller via power transmission means (not shown). 7, reference numeral 89 denotes a first rotation detection unit. The control unit (not shown) can grasp the amount of rotation of each roller provided in the document transport path by detecting the amount of rotation of the transport motor 50 using the first rotation detection unit 89. The first rotation detection unit 89 is a rotary encoder that includes a rotary disk 89a and a detection unit 89b.

[0076] The above-mentioned connection parts can also be arranged as shown in Fig. 14. In Fig. 14, scanner 1A differs from the configuration shown in Fig. 13 in that first connection part 71 is provided in the +Y direction with respect to circuit board 79. The circuit board 79 can also be provided in the orientation shown in Figure 15. In Figure 15, in scanner 1B, the board surface 79a of the circuit board 79 is oriented along the reading transport path R2. The orientation of the board surface 79a of the circuit board 79 along the reading transport path R2 means that the board surface 79a of the circuit board 79 is completely parallel to the reading transport path R2 or forms a slight angle (for example, less than 5°) with respect to the reading transport path R2. In Figure 15, reference numeral 66A denotes a modified example of the rear cover 66 described above.

[0077] 15 may also be arranged as shown in Fig. 16. In Fig. 16, the second connecting portion 72 is provided below the first connecting portion 71 in the scanner 1C. Furthermore, the arrangement of each connection part and the attitude of the circuit board 79 described above are merely examples and can be changed as appropriate.

[0078] In this embodiment, the USB cable 200 has a diameter of 3.6 mm, and the power cable 300 has a diameter of 6.0 mm. The USB cable 200 is more flexible than the power cable 300. In other words, the USB cable 200 has lower bending rigidity than the power cable 300.

[0079] Note that a storage medium having a connection portion conforming to USB Type-C, such as a USB memory, may be connected to the second connection portion 72 of this embodiment. When a storage medium, such as a USB memory, is connected to each of the second connection portion 72 and the first connection portion 71, the second connection portion 72 and the first connection portion 71 may be positioned so that the storage medium does not interfere with them.

[0080] 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.
