[0027] [Example 1] Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a reader 100 according to a first embodiment of the present invention will be described with reference to Fig. 1 to Fig. 21. Note that the same components in each embodiment are given the same reference numerals, and will be described only in the first embodiment, with the description of the components omitted in the following embodiments.

[0028] In the following, as an example of a reading device 100 according to the present invention, a multifunction device 1 is configured together with a recording device 200, which is an inkjet printer. However, the present invention is not limited to this configuration, and the reading device may be configured as a stand-alone device, or may be configured as a multifunction device together with a recording device other than an inkjet printer, such as an electrophotographic type or a dot impact type.

[0029] In the XYZ coordinate system shown in each figure, the X direction is the width direction of the device, the Y direction is the depth direction of the device, and the Z direction is the height direction and vertical direction of the device. The +Y direction is the direction from the back side of the device to the front side of the device, and the -Y direction is the direction from the front side of the device to the back side of the device. The front side of the device is the side that directly faces the operator, and which side of the device is the front side of the device is determined based on the device configuration and exterior design.

[0030] In the multifunction peripheral 1 of this embodiment, the reading device 100 is connected to the recording device 200 so as to be rotatable in the directions indicated by rotation directions D1 and D2 in Figures 1 and 2, with a rotation axis 201 provided at the end on the -Y side and extending in the X direction as a reference. For example, by rotating the reading device 100 in the rotation direction D1 relative to the recording device 200 from the state shown in Figure 1, the user can access an inkjet head (not shown) provided in the recording device 200.

[0031] As shown in Figures 4 and 5, the reading device 100 includes a main body 110 provided with a reading unit 111 that reads a document. The main body 110 includes a scanner main body 110A provided with the reading unit 111, and an automatic document feeder 110B. The automatic document feeder 110B is connected to the scanner main body 110A so that it can rotate relative to the scanner main body 110A in the directions indicated by rotation directions D1 and D2 in Figures 1 and 2, with a rotation axis 101 extending in the X direction and provided at the end of the scanner main body 110A in the -Y direction. The document can be read by opening the automatic document feeder 110B relative to the scanner main body 110A, placing a document on the scanner main body 110A, and then closing the automatic document feeder 110B relative to the scanner main body 110A.

[0032] 1 to 5, the reading device 100 is provided with a cover unit 130 and a discharge tray 122 which form an upper surface together with the base frame 121. The cover unit 130 and the discharge tray 122 are configured to be switchable between a non-feeding state shown in FIGS. 1 and 4 and a feeding state shown in FIGS. 2 and 5.

[0033] 1 and 2 and 4 and 5, the cover unit 130 has a rotation shaft 133 shown in FIG. 21 and other figures that extends in the Y direction relative to the main body unit 110, and can be opened and closed by rotating in rotation directions D3 and D4. In the closed, non-feeding state shown in FIGS. 1, 3, and 4, the cover unit 130 has a first surface 131 that forms the top surface. In the open, feeding state shown in FIGS. 2 and 5, the cover unit 130 has a second surface 132 opposite the first surface 131 that forms the support surface 114 that can support a document. In the non-feeding state, the discharge tray 122 is approximately horizontal like the base frame 121, and in the feeding state, the discharge tray 122 is inclined relative to the horizontal direction like the cover unit 130. In other words, the base frame 121 and the discharge tray 122, together with the cover unit 130, constitute a top surface forming part that forms the top surface of the reading device 100.

[0034] 2, 4, and 5, the reading device 100 is also provided with a document support unit 117 that can support a document before feeding. The document support unit 117 forms the support surface 114 together with the second surface 132 of the cover unit 130 in the open state.

[0035] The document supported by the document support unit 117 and the second surface 132 of the cover unit 130 is sent to the document transport path 115. As shown in FIGS. 4 and 5 , the document transport path 115 is provided with a reading unit 111 and a plurality of transport rollers 116. The reading unit 111 is movable along the X direction, and when reading a document set on the support surface 114, it moves to a predetermined reading position and reads an image of the document transported at the reading position. That is, the document supported by the document support unit 117 and the second surface 132 of the cover unit 130 is transported along the document transport path 115 by the plurality of transport rollers 116, which serve as a feeding unit that sends the document supported by the document support unit 117 toward the reading unit 111, and the image is read by the reading unit 111 on the scanner main body 110A and discharged to the discharge tray 122.

[0036] The following describes in detail the cover unit 130, which is a main part of the reading device 100 of this embodiment. In particular, the configuration of the lock unit 134, which maintains the cover unit 130 in a closed state relative to the main body unit when the cover unit 130 is in a closed state relative to the main body unit as shown in Figures 1 and 4, will be described in detail.

[0037] 3 and 21, the cover unit 130 has a grip portion 137A that can be gripped by the user and an operation portion 137 that serves as a point of force when opening and closing the cover unit 130 relative to the main body unit 110. Also, as shown in Figures 7 and 21, the cover unit 130 has a rotation shaft 133 that serves as a fulcrum when opening and closing the cover unit 130 relative to the main body unit 110. Furthermore, as shown in Figures 7 and 21, the cover unit 130 has a lock portion 134 that prevents the cover unit 130 from being opened when the cover unit 130 is closed relative to the main body unit 110.

[0038] Here, the locking portion 134 is provided near the pivot shaft 133. In other words, as shown in FIG. 21 , in the X direction, which is an intersecting direction intersecting with the Y direction, which is the axial direction of the pivot shaft 133, a distance X1 from the operating portion 137 to the locking portion 134 is configured to be longer than a distance X2 from the pivot shaft 133 to the locking portion 134. Here, the distance X1 from the operating portion 137 to the locking portion 134 can be the maximum distance from the center of the locking portion 134 in the X direction to the operating portion 137 in the X direction, or it may be the distance from the center of the locking portion 134 in the X direction to the center of the operating portion 137 in the X direction. On the other hand, the distance X2 from the pivot shaft 133 to the locking portion 134 can be the distance from the center of the locking portion 134 in the X direction to the center of the pivot shaft 133 in the X direction.

[0039] The reading device 100 of this embodiment has such a configuration, which can reduce the operating force required to lock the cover unit 130 when closing it and to unlock the cover unit 130 when opening it, thereby improving the operability for the user when opening and closing the cover unit 130. Furthermore, the reading device 100 of this embodiment has a configuration including the lock unit 134, which can also suppress rattling of the cover unit 130 relative to the main body unit 110 when the cover unit 130 is closed.

[0040] The configuration of the locking portion 134 will be described in further detail below. As shown in Fig. 10 and other figures, the cover portion 130 is provided with a rotation shaft 133, a locking portion 134, and an arm portion 136 at the end side in the -X direction. The position of the operating portion 137 in the X direction is approximately the center of the cover portion 130, as shown in Figs. 3 and 21 and other figures.

[0041] 11 and other figures, main body 110 is provided with bearing 118 that receives pivot shaft 133, and hemispherical engaged portion 112 that can engage with locking portion 134. Here, engaged portion 112 is in a position that does not contact locking portion 134 when cover portion 130 is in an open state relative to main body 110, and comes into contact with locking portion 134 when cover portion 130 is in a closed state relative to main body 110.

[0042] The positional relationship between the locking portion 134 and the engaged portion 112 from when the cover portion 130 is in an open state relative to the main body portion 110 until it is closed will be described below. The locking portion 134 and the engaged portion 112 do not come into contact with each other from when the cover portion 130 is in a state from which it is fully open relative to the main body portion 110 as shown in Fig. 1 until it reaches a state where it is somewhat open as shown in Fig. 12. Figs. 13 and 14 show the positional relationship between the locking portion 134 and the engaged portion 112 in the state shown in Fig. 12, but show that the locking portion 134 and the engaged portion 112 are in positions apart.

[0043] When the cover part 130 is further closed relative to the main body part 110 from the state shown in Fig. 12 to the state shown in Fig. 15, the locking part 134 and the engaged part 112 begin to come into contact with each other. Figs. 16 and 17 show the positional relationship between the locking part 134 and the engaged part 112 in the state shown in Fig. 15, and show that the locking part 134 is in contact with the engaged part 112 from below.

[0044] When cover portion 130 is further closed relative to main body portion 110 from the state shown in Fig. 15 to reach a state where cover portion 130 is completely closed relative to main body portion 110 as shown in Fig. 18, lock portion 134 is disposed in a position where it is locked by engaged portion 112. Figs. 19 and 20 show the positional relationship between lock portion 134 and engaged portion 112 in the state shown in Fig. 18, and show that lock portion 134 is abutted by engaged portion 112 from below, and is urged upward by engaged portion 112.

[0045] As shown in FIGS. 7 and 10 , the locking portion 134 has a protrusion 134A that protrudes in the Y direction, and a chamfered region 1341 is formed on the upper side of the protrusion 134A when the cover portion 130 is closed relative to the main body portion 110. On the other hand, the locking portion 134 does not have a chamfered region on the lower side when the cover portion 130 is closed relative to the main body portion 110. Also, as shown in FIG. 11 and other figures, the engaged portion 112 is hemispherical. With this configuration, the locking portion 134 engages with the engaged portion 112 with a weak force when closing the cover portion 130 relative to the main body portion 110. The locking portion 134 prevents the cover portion 130 from opening relative to the main body portion 110 when a weak force is applied to the engaged portion 112 in a direction that attempts to open the cover portion 130 relative to the main body portion 110 from a state in which the cover portion 130 is closed relative to the main body portion 110.

[0046] Explaining the above from another perspective, in the reading device 100 of this embodiment, when the cover part 130 is closed relative to the main body part 110, the lock part 134 is biased in the direction in which the cover part 130 is closed. With this configuration, the reading device 100 of this embodiment can prevent the cover part 130 from rattling when the cover part 130 is closed.

[0047] Explaining the above from yet another perspective, locking portion 134 has protrusion 134A, main body 110 has engaged portion 112 with which protrusion 134A engages when cover 130 is closed, and protrusion 134A has chamfered region 1341 serving as an engagement region for engaging with engaged portion 112. With this configuration, reading device 100 of this embodiment makes it easier for protrusion 134A serving as an engaging portion to engage with engaged portion 112, thereby particularly improving operability when closing and locking cover 130.

[0048] 21 and other figures, the cover part 130 is provided with locking parts 134 at both the end on the +Y side and the end on the -Y side in the Y direction corresponding to the axial direction of the rotation shaft 133. This provides a particularly stable locked state when the cover part 130 is closed and locked. However, this is not a limitation. The cover part 130 may have a locking part 134 provided at only one end of the cover part 130 in the axial direction of the rotation shaft 133.

[0049] However, it is preferable that the locking portion 134 be provided at least at the end on the +Y direction side, which is one end of the cover portion 130 in the axial direction of the rotation shaft 133, i.e., the end on the front side of the device. With this configuration, the locking portion 134 can be provided on the front side of the cover portion 130 as seen from the user, which makes it easier to lock the cover portion 130 by closing it, thereby particularly improving operability.

[0050] 2 and 6, the reading device 100 of this embodiment has a plurality of ribs 135 provided on the cover portion 130. In detail, the cover portion 130 has a plurality of ribs 135A extending along the X direction and a rib 135B extending along the Y direction. By being configured to have the ribs 135A, the reading device 100 of this embodiment reduces the difference in level when supporting a document between the cover portion 130 and the document support portion 117.

[0051] On the other hand, the cover part 130 has a rib 135B extending in the Y direction, i.e., in the axial direction of the rotation shaft 133, which enables the cover part 130 to be reinforced. As shown in Fig. 6, in the reading device 100 of this embodiment, the rib 135B is disposed at a position overlapping the axis of the rotation shaft 133 when viewed from the Z direction, and this configuration particularly effectively reinforces the cover part 130.

[0052] The rotation shaft 133 may be formed from a single rod-shaped member extending in the Y direction. By forming the rod-shaped member from metal, the rotation shaft 133 can be made highly rigid. By making the rotation shaft 133 formed from a single rod-shaped member highly rigid, deformation of the cover part 130 can be suppressed, and the high rigidity of the cover part 130 can suppress twisting of the cover part 130 when force is applied to the cover part 130, making locking and unlocking easier.

[0053] Here, in the reading device 100 of this embodiment, a buffer member 150 is provided on the contact surface 121A of the base frame 121, which is the position that comes into contact with the cover unit 130 when the cover unit 130 is closed. With this configuration, the reading device 100 of this embodiment can suppress noise when the cover unit 130 is closed and damage that accompanies closing the cover unit 130.

[0054] 6 to 9, the cover unit 130 has an arm unit 136. The discharge tray 122, which serves as an upper surface forming unit, has an abutment portion 122A at a position that faces the tip of the arm unit 136 when the cover unit 130 is closed. When the cover unit 130 is closed, the abutment portion 122A is pushed upward from below by the arm unit 136, causing the discharge tray 122 to assume a substantially horizontal orientation as shown in Fig. 4. When the cover unit 130 is opened, the abutment portion 122A moves to a position where it does not face the arm unit 136, causing the discharge tray 122 to assume an inclined position when viewed from the Y direction as shown in Fig. 5.

[0055] The contact portion 122A has a rib 1221 extending in the Y direction, which corresponds to the intersecting direction intersecting with the axial direction of the rotation shaft 133. With this configuration, the reading device 100 of this embodiment reinforces the contact portion 122A. Furthermore, by providing the rib 1221 as in this embodiment, it is possible to improve the sliding properties between the arm portion 136 and the contact portion 122A when opening and closing the cover portion 130.

[0056] 6 and 21, in the reading device 100 of this embodiment, the operation unit 137 is provided at an end of one side (+Y direction side) of the cover part 130 in the axial direction of the rotation shaft 133. That is, in the reading device 100 of this embodiment, the operation unit 137 is provided on the front side of the cover part 130 as seen from the user. Therefore, the reading device 100 of this embodiment can particularly improve operability when opening and closing the cover part 130.

[0057] 6 and 21, the operation unit 137 has a grip portion 137A that can be gripped by a user. The grip portion 137A is located on the other side (the -Y direction side) of the lock portion 134 in the axial direction of the rotation shaft 133. With this configuration, the reading device 100 of this embodiment uses a position close to the center in the axial direction (Y direction) of the rotation shaft 133 as the force point. For example, force is easily transmitted to both the lock portion 134 on the +Y direction side and the lock portion 134 on the -Y direction side, thereby particularly improving operability when opening and closing the cover unit 130. Furthermore, with this configuration, it is possible to prevent the grip portion 137A from protruding outward in the Y direction, thereby preventing the device from becoming large.

[0058] Moreover, the grip portion 137A is provided at a position including the center of the cover portion 130 in the X direction. With this configuration of the reading device 100 of this embodiment, the user can easily access the grip portion 137A, and the operability when opening and closing the cover portion 130 can be particularly improved. Furthermore, with this configuration, deformation of the cover portion 130 can be suppressed. However, there are no particular limitations on the position, size, shape, etc. of the operation portion 137 on the cover portion 130.

[0059] [Example 2] Next, the reading device 100 of the second embodiment will be described with reference to FIG. 22. In FIG. 22, components common to those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. Note that FIG. 22 corresponds to FIG. 21 showing the reading device 100 of the first embodiment. Here, the reading device 100 of the second embodiment has the same configuration as the reading device 100 of the first embodiment, except for the configuration of the cover unit 130. Therefore, except for the parts described below, the reading device 100 of the second embodiment has the same features as the reading device 100 of the first embodiment.

[0060] 22 , in the cover unit 130 of the reading device 100 of this embodiment, the operation unit 137 is provided at the end of the cover unit 130 on the +X direction side. However, similar to the cover unit 130 of the reading device 100 of the first embodiment, the cover unit 130 is configured so that the distance X1 from the operation unit 137 to the lock unit 134 is longer than the distance X2 from the turning shaft 133 to the lock unit 134 in the X direction, which is an intersecting direction with the Y direction, which is the axial direction of the turning shaft 133. Even with this configuration, similar to the reading device 100 of the first embodiment, it is possible to improve the operability for the user when opening and closing the cover unit 130.

[0061] It goes without saying that the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention as defined in the claims, and these modifications are also included within the scope of the present invention.
