[0009] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention claimed. Although multiple features are described in the embodiments, not all of these multiple features are necessarily essential to the invention, and multiple features may be combined arbitrarily. Furthermore, in the accompanying drawings, the same reference numerals are used to designate the same or similar components, and redundant explanations will be omitted.

[0010] First Embodiment <Overall configuration of electrical equipment> FIG. 1 is an external view of an electrical device 1 according to one embodiment of the present invention, viewed from the front. The electrical device 1 of this embodiment is an inkjet recording device (multifunction peripheral) that ejects ink as a liquid to record on a recording medium, but the present invention is also applicable to various electrical devices other than inkjet recording devices. In the figure, arrows X and Y indicate horizontal directions that are orthogonal to each other, and arrow Z indicates the up-down direction (direction of gravity). The X direction is the width direction (left-right direction) of the electrical device 1. The Y direction is the depth direction (front-back direction) of the electrical device 1.

[0011] "Recording" not only includes the formation of meaningful information such as characters and figures, but also includes the formation of images, patterns, designs, etc. on a recording medium, whether meaningful or insignificant, or the processing of the medium, regardless of whether it is manifested in a way that can be perceived visually by humans. In addition, although sheet-like paper is assumed as the "recording medium" in this embodiment, it may also be cloth, plastic film, etc.

[0012] The electrical device 1 has a flat rectangular parallelepiped shape overall, and includes a device main body 2 and an operation panel 5. The device main body 2 includes a document reading unit 3 and a recording unit 4. The operation panel 5 has a rectangular shape that is long in the X direction overall, and includes a plurality of operation buttons 50 that accept user operations, and a display unit 51. The plurality of operation buttons 50 include a power key, a selection key, etc. The display unit 51 is an electronic image display device such as an LCD that displays information to the user, and may be a touch panel.

[0013] The document reading unit 3 has a housing 30 that forms its exterior, and is supported so as to be rotatable about a rotation center line X1 in the X direction relative to the recording unit 4. The rotation center line X1 is located at the rear side of the device main body 2. The document reading unit 3 is a scanner that reads an image of a document and generates image data. The image read by the document reading unit 3 can be recorded on a recording medium by the recording unit 4.

[0014] A discharge section 42 into which recorded recording media are discharged is formed at the front of the recording unit 4. A cassette 49 that stores recording media before recording is provided below the discharge section 42. A stacking section 43 into which recording media before recording are stacked is provided at the rear of the recording unit 4. The stacking section 43 is a foldable tray, and FIG. 1 shows the stacking section 43 in a folded storage state.

[0015] The recording unit 4 will be described with reference to FIG. 2 in addition to FIG. 1. FIG. 2 is a diagram showing the internal mechanism of the recording unit 4. The recording unit 4 includes an ejection head 46 that ejects liquid. The ejection head 46 of this embodiment is a recording head that performs recording by ejecting ink supplied from container 44Bk, container 44C, container 44M, or container 44Y onto a recording medium. The ejection head 46 may be composed of two ejection heads: one ejecting ink supplied from container 44Bk and the other ejecting ink supplied from container 44C, container 44M, and container 44Y. The ejection head 46 has an ejection surface on which a plurality of nozzles that eject ink are formed. Each nozzle is provided with, for example, an electrothermal conversion element (heater). The electrothermal conversion element heats the ink when energized to cause it to bubble, and the resulting bubble-generating energy ejects the ink.

[0016] The ejection head 46 is mounted on a carriage 45. The carriage 45 is reciprocated in the X direction (main scanning direction) by a drive unit 48. The drive unit 48 includes a drive pulley and a driven pulley (only one of the pulleys, 48b, is shown in FIG. 2) that are spaced apart in the X direction, and an endless belt 48a wound around the pulley 48b. The drive unit 48 also includes a carriage motor (not shown) that serves as a drive source for rotating the drive pulley. The carriage 45 is connected to the endless belt 48a, and moving the endless belt 48a causes the carriage 45 to move in the X direction. An image is recorded by ejecting ink from the ejection head 46 onto a recording medium during the movement of the carriage 45. This operation is sometimes called recording scanning.

[0017] As described above, the electrical device 1 of this embodiment is a serial type inkjet recording device in which the ejection head 46 is mounted on a reciprocating carriage 45. However, the present invention is also applicable to other recording devices, such as an inkjet recording device equipped with a so-called full-line ejection head (recording head) provided with multiple nozzles that eject liquid in an area corresponding to the width of the recording medium.

[0018] The electrical device 1 includes a transport unit 47 that transports the recording medium. The transport unit 47 is a mechanism that transports the recording medium in the Y direction (sub-scanning direction). The transport unit 47 includes a transport roller 47a and a transport motor (not shown) that is a drive source that rotates the transport roller 47a. Multiple driven rollers 47b are pressed against the transport roller 47a, and the recording medium is sandwiched between these nip portions. The rotation of the transport roller 47a intermittently transports the recording medium to the ejection head 46. The recording operation is performed by alternately repeating the transport operation of the recording medium by the transport unit 47 and recording scanning.

[0019] The recording unit 4 has a housing 40 that forms its exterior. The housing 40 includes front covers 40a and 40b that are spaced apart in the X direction. The operation panel 5 is disposed between the front covers 40a and 40b. The front cover 40a has a plurality of windows 41C, 41M, and 41Y formed therein. The front cover 40b has a window 41Bk formed therein. The windows 41Bk, 41C, 41M, and 41Y are openings that allow the user to view the internal configuration of the recording unit 4.

[0020] In this embodiment, the user can visually check the remaining amount of liquid contained in containers 44Bk, 44C, 44M, and 44Y (hereinafter referred to as containers 44 when collectively referred to or when no distinction is made) through windows 41Bk, 41C, 41M, and 41Y. Container 44 is an ink tank that contains ink as the liquid. Front wall 44a of container 44 is made of a translucent material and forms a remaining amount indicator that allows the amount of liquid inside to be visually checked.

[0021] The four containers 44 contain different types of ink. In the present embodiment, black ink is contained in container 44Bk, cyan ink in container 44C, magenta ink in container 44M, and yellow ink in container 44Y. The types of ink are not limited to four as in the present embodiment, and may be one type or multiple types other than four, as long as the number of containers 44 is equal to or greater than the number of types of liquid ink.

[0022] FIG. 3(A) is a rear view of the front cover 40a. The front cover 40a is covered with a sheet-like light-transmitting member 410 that transmits light so as to cover the multiple windows 41C, 41M, and 41Y. FIG. 3(B) is an explanatory diagram of the light-transmitting member 410. Engagement holes 410a and 410b are formed in the light-transmitting member 410. An engagement protrusion 411 that engages with the engagement hole 410a and an engagement protrusion 412 that engages with the engagement hole 410b are formed on the rear surface of the front cover 40a. Engagement of the engagement holes 410a, 410b with the engagement protrusions 411, 412 holds the light-transmitting member 410 on the rear surface of the front cover 40a. A similar light-transmitting member is also held on the rear surface of the front cover 40b.

[0023] FIG. 4 is a cross-sectional view of the structure around the container 44Y taken along line DD in FIG. 1. A light-transmitting member 410 is interposed between the window 41Y and the front wall 44a of the container 44Y. The light-transmitting member 410 prevents foreign matter from coming into contact with the container 44Y from the outside through the window 41Y. This prevents the container 44Y from being damaged by foreign matter and causing ink leakage. The engagement protrusion 411 is located above the window 41Y, allowing the front wall 44a of the container 44Y to be close to the window 41Y. The same is true for the engagement protrusion 412. This allows for a larger capacity for the container 44Y and improved visibility of the remaining amount through the front wall 44a. The same is true for the windows 41M, 41C, and 41Bk and the containers 44M, 44C, and 44Bk.

[0024] <Operation panel and its support structure> The operation panel 5 will now be described. The operation panel 5 is supported by the device body 2 so as to be rotatable about a rotation center line X2 (FIG. 1) in the X direction that passes through the top of the operation panel 5. In this embodiment, the operation panel 5 is supported by the recording unit 4. FIG. 1 shows the operation panel 5 in the closed position, and FIG. 5 shows the operation panel 5 in the open position. In the closed position, the operation panel 5 is in a vertical position with its front surface 5a vertical and is stored along the front of the device body 2. In the open position, the operation panel 5 is in an inclined position with its front surface 5a tilted from the vertical direction and a lower portion of the operation panel 5 protrudes forward from the front of the device body 2. In the following description of the structure of the operation panel 5, the X, Y, and Z directions refer to the directions when the operation panel 5 is in the closed position, unless otherwise specified.

[0025] 6 is a front view of the recording unit 4 with the operation panel 5 removed. A support frame 6 is fixed between the front cover 40a and the front cover 40b of the recording unit 4, and the operation panel 5 is attached to the support frame 6.

[0026] FIG. 7 is an exploded perspective view of the operation panel 5 and the support frame 6. In FIG. 7, the configuration arranged inside the operation panel 5 is not shown. The operation panel 5 has a base member 52 that supports the operation buttons 50 and the display unit 51 and forms the back surface 5b of the operation panel 5, and a cover panel 53 that covers the front side of the base member 52 and forms the front surface 5a of the operation panel 5. The base member 52 and the cover panel 53 have a rectangular outline. Fixing portions 54 to which shaft members 65 are fixed are formed on both ends of the upper side of the base member 52 in the X direction. The shaft member 65 is a cylindrical member that extends in the X direction and defines the rotation center line X2 of the operation panel 5.

[0027] The configuration of the base member 52 will be further described with reference to Figures 8(A) and 8(B) in addition to Figure 7. Figure 8(A) is a plan view of the base member 52, and Figure 8(B) is a front view of the base member 52.

[0028] A cover portion 56 that covers at least a part of an electric cable 58 (described later) is integrally formed so as to protrude from the rear surface 5b at one end in the X direction of the base member 52. The cover portion 56 has an inlet 56a and an outlet 56b, and has a duct shape that is bent at approximately 90 degrees from the inlet 56a to the outlet 56b.

[0029] The entrance 56a opens into a component placement section 57, which is the front surface of the base member 52 (the surface on the cover panel 53 side). In this embodiment, the entrance 56a is rectangular. The component placement section 57 is equipped with the operation buttons 50, the display unit 51, and a circuit board 57 (described later). The exit 56b opens in the Z direction at the top of the back of the base member 52. The opening surface of the entrance 56a is on a vertical plane (XZ plane), and the opening surface of the exit 56b is on a horizontal plane (XY plane). The cover portion 56 has a pair of left and right side wall portions 56c and a bottom wall portion 56d between the pair of side wall portions 56c. The bottom wall portion 56d has a curved portion that is bent in an arc shape around the rotation center line X2.

[0030] An arm member 55 is rotatably attached to the other end of the base member 52 in the X direction at a hinge portion 55b. The hinge portion 55b supports the arm member 55 so that it can rotate about an axis in the X direction. The arm portion 55 extends rearward from the back portion of the base member 52, and a cam surface 55a is formed on the upper surface thereof.

[0031] The configuration of the support frame 6 will be further described with reference to Fig. 6, Fig. 9(A), and Fig. 9(B) in addition to Fig. 7. Fig. 9(A) is a plan view of the support frame 6, and Fig. 9(B) is a front view of the support frame 6.

[0032] The support frame 6 has a rectangular outline. An abutment portion 6a is formed on the upper edge of the support frame 6, against which the document reading unit 3 partially abuts when the document reading unit 3 is closed. In this embodiment, the abutment portion 6a is a flat surface that extends in a strip shape in the X direction.

[0033] Left and right bearings 64 are formed on the upper front surface of the support frame 6 and are spaced apart in the X direction. The bearings 64 have C-shaped engaging portions that engage with shaft members 65. The two shaft members 65 fixed to the two fixing portions 54 of the base member 52 of the operation panel 5 engage with the bearings 64, respectively, so that the operation panel 5 is supported on the support frame 6 so as to be freely rotatable.

[0034] The support frame 6 has a mounting section 60 on the front surface of which the operation panel 5 is mounted. The mounting section 60 is located on the front surface of the device main body 2, particularly on the front surface of the recording section 4. An opening 61 is formed in the mounting section 60. An electric cable 58, which will be described later, extends from the rear surface of the operation panel 5 through the opening 61 into the device main body 2 (inside the recording section 4 in this embodiment). The opening 61 is formed in a position corresponding to the cover section 56, and the cover section 56 is inserted into the opening 61.

[0035] The opening 61 has a rectangular shape defined by inner walls 61a to 61d. The inner wall 61a forms the top surface of the opening 61, and the inner wall 61b forms the bottom surface. The inner walls 61c and 61d form the left and right side surfaces of the opening 61. The opening 61 is provided with a restricting wall 62. The restricting wall 62 is a plate-shaped member that protrudes from the inner wall 61a toward the inner wall 61d, and its tip 62a is located midway between the inner walls 61a and 61d.

[0036] A gap is formed between the tip end 62a and the inner wall 61b. When the cover portion 56 is also inserted into the opening 61, the bottom wall portion 56d of the cover portion 56 is located between the tip end 62a and the inner wall 61b. The restriction wall 62 has a width in the X direction, and gaps are formed between the restriction wall 62 and the inner wall 61c and between the restriction wall 62 and the inner wall 61d. When the cover portion 56 is also inserted into the opening 61, one of the pair of side wall portions 56c of the cover portion 56 is located between the restriction wall 62 and the inner wall 61c, and one of the pair of side wall portions 56c is located between the restriction wall 62 and the inner wall 61d. When the cover portion 56 is also inserted into the opening 61, the restriction wall 62 protrudes into the cover portion 56 from the outlet 56b.

[0037] The mounting portion 60 also has an opening 60a formed on the opposite side of the opening 61 in the X direction, through which the arm member 55 passes. An angle maintaining mechanism 63 that engages with the arm portion 55 passing through the opening 60a is mounted on the back surface of the support frame 6. The support frame 6 also has a canopy portion 67 that protrudes forward (towards the operation panel 5) from the upper edge of the opening 61.

[0038] Next, reference is made to Figure 10. Figure 10 is a cross-sectional view of the operation panel 5 and its surroundings taken along line AA in Figure 1. Inside the operation panel 5, a circuit board 57 is housed and fixed to a base member 52 in a vertical position. The circuit board 57 includes electrical circuits related to the operation buttons 50 and the display unit 51. When the operation panel 5 is in the stored state as shown in Figure 10, the operation panel 5 is positioned so as to overlap with a mounting portion 60 of the support frame 6, and the back surface 5b of the operation panel 5 faces the mounting portion 60. In addition, the protrusion 52a of the base member 52 abuts against the mounting portion 60, restricting the operation panel 5 from rotating further toward the mounting portion 60.

[0039] Next, the operation of the angle maintaining mechanism 63 will be described with reference to Figures 11 and 12. Figure 11 is a cross-sectional view of the operation panel 5 and its surroundings taken along line BB in Figure 1. Figure 12 is a cross-sectional view showing the operation panel 5 rotated from the state in Figure 11 to the open position (Figure 5). The angle maintaining mechanism 63 includes a pressing member 63a and an elastic member 63b that biases the pressing member 63a against the cam surface 55a of the arm member 55. In this embodiment, the elastic member 63b is a coil spring.

[0040] In this embodiment, cam surface 55a is a step formed on the upper surface of arm member 55. In the closed position shown in FIG. 11, the tip of pressing member 63a abuts against a valley portion of cam surface 55a, and angle maintaining mechanism 63 generates a certain resistance force against rotation of operation panel 5 from the closed position to the open position. When a user rotates operation panel 5 in the open direction, pressing member 63a is displaced against the bias of elastic member 63b, and its tip overcomes the valley portion of cam surface 55a, thereby releasing the closed position. In the open position shown in FIG. 12, the tip of pressing member 63a abuts against another valley portion of cam surface 55a, and angle maintaining mechanism 63 generates a certain resistance force against return of operation panel 5 from the open position to the closed position. This maintains operation panel 5 in the open position. When the user rotates the operation panel 5 in the closing direction, the pressing member 63a is displaced against the bias of the elastic member 63b, and its tip overcomes the valley of the cam surface 55a, thereby releasing the open position.

[0041] Next, the functions of the cover portion 56 and the restriction wall 62 will be described with reference to Figures 13(A) and 13(B). Figure 13(A) is a cross-sectional view of the operation panel 5 and its surroundings taken along line CC in Figure 1. Figure 13(B) is a cross-sectional view showing the state in which the operation panel 5 has been rotated from the state in Figure 13(A) to the open position (Figure 5).

[0042] The electric cable 58 is a cable that electrically connects the circuit board 57 and a control circuit board provided in the device main body 2. In this embodiment, the control circuit board is a circuit board provided in the recording unit 4. The electric cable 58 is, for example, a flexible flat cable. The electric cable 58 is routed to the recording unit 4 through the cover portion 58 of the operation panel 5 and the opening 61 of the support frame 6.

[0043] Within the cover portion 58, the position of the electric cable 58 in the Z direction is restricted by a restricting wall 62. When the operation panel 5 is in the closed position as shown in FIG. 13(A), the electric cable 58 passes below the restricting wall 62 and is restricted from being displaced upward by a tip 62a of the restricting wall 62. There is a possibility that the user may touch a portion P1 at the top of the operation panel 5. The restricting wall 62 can control the position of the electric cable 58 to a position farther away from the portion P1, so that even if the user touches the portion P1, the effect of static electricity on the electric cable 58 can be reduced.

[0044] 13(B), when the operation panel 5 is rotated to the open position, the operation panel 5 moves away from the mounting portion 60. In the open position, a larger gap is created between the rear surface 5b of the operation panel 5 and the mounting portion 60 than in the closed position. However, the electric cable 58 is covered by the cover portion 56 and is therefore prevented from being exposed. In this way, the cover portion 56 can prevent the electric cable 58 from being exposed when the position of the operation panel 5 is changed. Because the position of the electric cable 58 is controlled by the regulating wall 62 even while the position of the operation panel 5 is being changed, the electric cable 58 can be prevented from being displaced to an unintended position or from getting caught on other components.

[0045] Even when the operation panel 5 is in the open position, the cover portion 56 is inserted into the opening 61, and the edge 56e of the cover portion 56 is located closer to the recording unit 4 than the opening 61. The bottom wall portion 56d can always cover the lower side of the electric cable 58, regardless of the rotational position of the operation panel 5. In the present embodiment, one of the pair of side walls 56c of the cover portion 56 is located between the restriction wall 62 and the inner wall 61c, and the other of the pair of side walls 56c is located between the restriction wall 62 and the inner wall 61d. Because the pair of side walls 56c extend above the tip end 62a of the restriction wall 62, both sides of the electric cable 58 in the X direction can always be covered, regardless of the rotational position of the operation panel 5.

[0046] When the operation panel 5 is rotated from the closed position to the open position, there is a possibility that the user may touch the lower part P2 of the opening 61. However, because the electric cable 58 is covered by the bottom wall part 56d of the cover part 56, it is possible to reduce the effects of static electricity on the electric cable 58. When the operation panel 5 is in the open position, the edge 56e is located higher than the lower part P2 of the opening 61. The edge 56e prevents the electric cable 58 from drooping downward, thereby further reducing the effects of static electricity on the electric cable 58.

[0047] The bottom wall 56d has a curved portion that is bent in an arc shape around the rotation center line X2, so that the gap between the lower edge of the opening 61 and the bottom wall 56d can be kept constant and narrow while the operation panel 5 is rotating. This makes it possible to prevent foreign matter from entering the recording unit 4 through the gap between the lower edge of the opening 61 and the bottom wall 56d.

[0048] Because the tip 62a of the restriction wall 62 is located approximately in the center of the opening 61 in the Z direction, a constant distance can be formed between the part P1 and the lower part P2 and the electric cable 58, whether the operation panel 5 is in the closed position or the open position. Therefore, the effect of static electricity on the electric cable 58 can be reduced whether the operation panel 5 is in the open position or the closed position.

[0049] The support frame 6 has a eaves portion 67 on the upper edge of the opening 61, and if a foreign object falls from above, the eaves portion 67 will hold the foreign object, preventing it from entering the operation panel 5 or the opening 61. The eaves portion 67 also forms a recess 66. The recess 66 makes it easier to catch foreign objects, and when the operation panel 5 is in the open position, the top of the operation panel 5 (the upper edge of the cover panel 53) fits into the recess 66, thereby avoiding interference.

[0050] <Sealing structure between the document reading unit and the recording unit> Next, we will explain the sealing structure between the document reading unit 3 and the recording unit 4 when the document reading unit 3 is in the closed position. Figures 14(A) and 14(B) are cross-sectional views of the boundary between the document reading unit 3 and the recording unit 4, and correspond to the cross-sectional view along line CC in Figure 1. Figure 14(A) shows the document reading unit 3 in a state where it is slightly open relative to the recording unit 4, and Figure 14(B) shows the closed state. Figure 15(A) is a front view of the front cover 31 of the housing 30, and Figure 15(B) is a bottom view of the front cover 31.

[0051] The front cover 31 has an elastically deformable lower edge 32. When the document reading unit 3 is closed, as shown in FIG. 14(B), the lower edge 32 abuts against the abutment portion 6a of the support frame 6. Because the lower edge 32 is elastically deformable, it is in close contact with the abutment portion 6a of the support frame 6. Ink mist may be generated during the recording operation in the recording unit 4. This mist can leak from the inside of the recording unit 4 to the outside through gaps. The close contact between the lower edge 32 and the abutment portion 6a reduces the mist that leaks from inside the recording unit 4 to above the operation panel 5.

[0052] Second Embodiment In the first embodiment, the position of the electric cable 58 is restricted by the tip end 62a of the restricting wall 62, but a passage portion through which the electric cable 58 passes may be formed in the restricting wall 62, and the position of the electric cable 58 may be restricted by the passage portion. Figures 16(A) and 16(B) are cross-sectional views showing the restricting wall 62' in this embodiment, and correspond to Figures 13(A) and 13(B).

[0053] The restricting wall 62' is longer in the Z direction than the restricting wall 62 of the first embodiment, and has a passing portion 62b formed in the middle thereof. The passing portion 62b is a hole that penetrates the restricting wall 62' in the thickness direction. The passing portion 62b may be a notch.

[0054] The function of the restricting wall 62' is the same as that of the restricting wall 62 of the first embodiment, but since the position of the electric cable 58 in the vertical and horizontal directions is restricted by the passing portion 62b, the position of the electric cable 58 can be controlled more precisely.
