Description

Technical Field

[0001] The present disclosure relates to an image forming apparatus such as a printer, a copier, a facsimile machine, a multifunction peripheral, or the like. Background Art

[0002] Image forming devices including printers, copiers, fax machines and multi-function peripherals are provided with various boards, such as high-voltage boards and control boards for controlling electrical components (such as various motors, sensors and switches). These boards are mainly arranged at a position close to the rear surface of the image forming device, and the electrical components electrically connected to these boards by means of wiring harnesses are also generally arranged at a position close to the rear surface of the image forming device. However, the arrangement of each unit provided in the image forming device sometimes makes it difficult to gather the electrical components including the boards at a position close to the rear surface, in which case some electrical components will inevitably be arranged at a position close to the front surface. Even in this case, in order to facilitate the user to replace and maintain the operation of the electrical components and to achieve the miniaturization of the device, the electrical components are also connected to each other by means of wiring harnesses in a space-saving manner. As described in Japanese Patent Application Publication No. 2022-175261, there is a configuration in which the electrical components arranged at a position close to the front surface of the device are electrically connected to the electrical components arranged at a position close to the rear surface via a relay unit of the wiring harness. Summary of the invention

[0003] According to some embodiments, an image forming device includes: an image forming unit configured to form an image on a sheet; a conveying unit configured to convey the sheet in a conveying direction along a first direction; a housing including a first frame disposed on a first side of the conveying unit in a second direction intersecting the first direction, and a second frame disposed on a second side of the conveying unit opposite to the first side in the second direction; a first electrical component disposed on the first frame of the housing; a second electrical component disposed on the second frame of the housing; and a wire configured to electrically connect the first electrical component to the second electrical component, wherein the conveying unit is configured to move along a third direction between a first position at which the conveying unit conveys the sheet and a second position different from the first position, the third direction being perpendicular to an image forming surface of the sheet conveyed by the conveying unit at the first position, wherein a first space and a second space communicating with the first space are provided in the housing, wherein the conveying unit is configured to move between the first position and the second position through the first space, and wherein the wire is disposed in the second space and is located on a first side of the second position, while the first position is located on a second side of the second position, and the second side of the second position is opposite to the first side of the second position.

[0013] Image forming devices for commercial printing operate at a higher speed and have a higher printing accuracy, and therefore tend to include many electrical components. In addition, image forming devices for commercial printing generally include a main housing and other housings connected to the main housing at the side of the main housing, which makes it difficult to access the electrical components in the main housing from the side of the main housing. Therefore, replacement and maintenance of the electrical components are generally performed from the easily accessible front side. In this case, the wiring harness is routed from the electrical components disposed at a position close to the front surface to the electrical components disposed at a position close to the rear surface. As the number of electrical components increases, the number of wiring harnesses for supplying power and / or transmitting electrical signals also increases, thereby requiring a large space to route these wiring harnesses, which results in an increase in the size of the image forming device due to the allocation of space to the wiring.

[0014] The following exemplary embodiments can provide an image forming apparatus in which a wiring harness is provided between a first electric component disposed at the front and a second electric component disposed at the rear without increasing the size of the image forming apparatus.

[0015] Various exemplary embodiments, features, and aspects of the present disclosure will be described below with reference to the drawings. Figure 1An image forming apparatus according to the present exemplary embodiment is described. An inkjet recording apparatus 100 will be described as an example of an image forming apparatus, which is a sheet-type apparatus that forms an image on a sheet by using ink and a reaction solution. The sheet may be any recording material capable of receiving ink, such as paper (such as ordinary paper or thick paper), a plastic film sheet for an overhead projector, a sheet having a special shape (such as an envelope or index paper), or a cloth sheet.

[0016] In this specification, the side where the user stands when operating the inkjet recording device 100 is called the front surface (or front side), and the side opposite to the front surface is called the rear surface (or rear side). The left and right sides seen from the front surface are respectively called left and right. Figure 1 The inkjet recording apparatus 100 is shown as viewed from the front surface.

[0017] <Inkjet Recording Device>

[0018] like Figure 1 As shown in FIG. 1 , the inkjet recording apparatus 100 includes a sheet feeding module 1000, a printing module 2000, a drying module 3000, a fixing module 4000, a cooling module 5000, a reversing module 6000, and a stacking module 7000. The sheet S fed from the sheet feeding module 1000 undergoes various processes in the respective modules during conveyance along a conveyance path, and is finally discharged to the stacking module 7000.

[0019] The sheet feeding module 1000, the printing module 2000, the drying module 3000, the fixing module 4000, the cooling module 5000, the reversing module 6000, and the stacking module 7000 may each have a separate housing, and these housings may be connected to form the inkjet recording apparatus 100. Alternatively, the sheet feeding module 1000, the printing module 2000, the drying module 3000, the fixing module 4000, the cooling module 5000, the reversing module 6000, and the stacking module 7000 may be provided in one housing.

[0020] The sheet feeding module 1000 includes containers 1500a, 1500b, and 1500c for storing sheets S. The containers 1500a to 1500c are provided so as to be pulled out in a direction toward the front side to store sheets S therein. The sheets S are fed one by one from each of the containers 1500a to 1500c through a separation belt and a conveying roller and conveyed to the printing module 2000. The number of the containers 1500a to 1500c is not limited to three, and may be one, two, or four or more.

[0021] The printing module 2000 includes a pre-image forming conveying unit 2400 (see Figure 2), a printing belt unit 2200, and a recording unit 2300. The inclination and position of the sheet S conveyed from the sheet feeding module 1000 are corrected by the conveying unit 2400 before image formation, and the corrected sheet S is conveyed to the printing belt unit 2200. The recording unit 2300 is set at a position facing the printing belt unit 2200 with respect to the conveying path. The recording unit 2300 is a sheet processing unit, which performs recording processing (printing) to form an image on the conveyed sheet S from above using a recording head. The sheet S is attracted and conveyed by the printing belt unit 2200, so that a gap is left between the sheet S and the recording head. A plurality of recording heads are set along the conveying direction (first direction). According to the present exemplary embodiment, the recording unit 2300 includes a total of five line-type recording heads, which correspond to four colors of ink, namely yellow (Y), magenta (M), cyan (C), and black (Bk), and a reaction solution.

[0022] The number of recording heads is not limited to five. As an inkjet recording method, a method using a heating element, a method using a piezoelectric element, a method using an electrostatic element, and a method using a micro-electromechanical system (MEMS) element can be adopted. Ink of each color is supplied to the recording head from an ink cartridge (not shown) via an ink tube. The sheet S printed in the recording unit 2300 is conveyed by the printing belt unit 2200, and an online scanner (not shown) provided at a downstream position of the recording unit 2300 in the conveying direction can detect misalignment and color density of an image formed on the sheet S and correct the printed image.

[0023] The drying module 3000 includes a decoupling unit 3200, a drying belt unit 3300, and a hot air blowing unit 3400. The drying module 3000 reduces the liquid content of the ink applied to the sheet S, which improves the performance of fixing the ink to the sheet S in the fixing module 4000 as a subsequent module. The sheet S on which the image is formed is conveyed to the decoupling unit 3200 provided in the drying module 3000. The decoupling unit 3200 generates a frictional force between the sheet S and the belt by the pressure of the wind blown from above, and causes the belt to convey the sheet S. Therefore, the sheet S on the belt is conveyed by the frictional force, thereby preventing the sheet S from being deviated during conveyance by the printing belt unit 2200 and the decoupling unit 3200.

[0024] The sheet S conveyed from the decoupling unit 3200 is sucked and conveyed by the drying belt unit 3300 , and the hot air blowing unit 3400 provided above the belt blows hot air to dry the ink applied on the sheet S.

[0025] The fixing module 4000 includes a fixing belt unit 4100. The fixing belt unit 4100 includes an upper belt unit 4110 and a lower belt unit 4120. The fixing belt unit 4100 allows the sheet S conveyed from the drying module 3000 to pass through a path 1 between the heated upper belt unit 4110 and the heated lower belt unit 4120 to fix ink onto the sheet S.

[0026] The cooling module 5000 includes a plurality of cooling units 5100 for cooling the high-temperature sheet S conveyed from the fixing module 4000. For example, the cooling unit 5100 draws external air into a cooling box using a fan to increase the pressure in the cooling box, and cools the sheet S by blowing air from the cooling box through a nozzle under pressure. The cooling units 5100 are provided on both sides of the conveying path of the sheet S to cool both sides of the sheet S.

[0027] The cooling module 5000 includes a conveying path switching unit 5002. The conveying path switching unit 5002 switches the conveying path of the sheet S based on whether the sheet S is to be conveyed to the reversing module 6000 or to a duplex conveying path for duplex printing to form images on both sides of the sheet S.

[0028] The reversing module 6000 includes a reversing unit 6400. The reversing unit 6400 reverses the front and back sides of the sheet S being conveyed and changes the orientation of the sheet S to be discharged to the stacking module 7000 between the front and back sides. The stacking module 7000 includes a top tray 7200 and a stacking unit 7500 for stacking the sheets S conveyed from the reversing module 6000.

[0029] In duplex printing, the sheet S is conveyed to the conveying path below the cooling module 5000 by the conveying path switching unit 5002. Subsequently, the sheet S passes through the duplex conveying path in the fixing module 4000, the drying module 3000, the printing module 2000, and the sheet feeding module 1000 and returns to the printing module 2000. The duplex conveying unit of the fixing module 4000 includes a reversing unit 4200 that reverses the front and back sides of the sheet S. An image is formed with ink on the other side of the sheet S returned to the printing module 2000, on which image formation is not performed, and the sheet S is discharged to the stacking module 7000 via the drying module 3000, the fixing module 4000, the cooling module 5000, and the reversing module 6000.

[0030] <Print Module>

[0031] Reference Figure 2 The printing module 2000 is described. Figure 2As shown in FIG. 2 , in addition to the pre-image formation conveying unit 2400, the printing belt unit 2200, and the recording unit 2300, the printing module 2000 further includes a head maintenance unit 2600 and a relay unit 2500. The pre-image formation conveying unit 2400 is disposed at an upstream position of the printing belt unit 2200 in the conveying direction, and conveys the sheet S to the printing belt unit 2200 according to the driving of the driving motor 2202. The head maintenance unit 2600 is disposed above the pre-image formation conveying unit 2400. The head maintenance unit 2600 is disposed to be movable relative to the recording unit 2300, so that the recording head included in the recording unit 2300 is protected and cleaned when printing is not performed.

[0032] The housing 2100 of the printing module 2000 includes a front side plate arranged at the front, a rear side plate arranged at the rear and supporting each unit together with the front side plate, a stay connecting the front side plate and the rear side plate, a frame supporting the front side plate and the rear side plate, and other plate-shaped metal sheets. The housing 2100 includes an outer cover that forms an appearance and can be removed or opened and closed. The outer cover includes, for example, a front surface cover at the front, side surface covers at the left and right sides, and a rear surface cover at the back.

[0033] The printing belt unit 2200 and the image forming pre-conveyor unit 2400 are detachably disposed in the housing 2100. The user removes the front surface cover to perform maintenance and replacement of the components, and removes the printing belt unit 2200 or the image forming pre-conveyor unit 2400 from the housing 2100 as needed. In the present exemplary embodiment, in the case where the printing belt unit 2200 or the image forming pre-conveyor unit 2400 is removed from the housing 2100, the user first removes the wiring harness from the relay unit 2500, so that the electrical connection can be released. The wiring harness is a bundle of a plurality of signal lines (cables) that transmit different electrical signals.

[0034] <Relay Unit>

[0035] In the present exemplary embodiment, electrical components such as a motor for operating the printing belt unit 2200, a motor for operating the image forming pre-conveyance unit 2400, and a detection sensor (not shown) for detecting the sheet S are provided at a position close to the front surface of the printing module 2000. Meanwhile, at a position close to the rear surface of the printing module 2000, a board 2700 (see FIG. 27 ) such as a control board for controlling the overall operation of the printing module 2000 and the rotation of the motor is provided. Figure 6 ). In order to electrically connect the electrical components disposed at a position close to the front surface with the board 2700 disposed at a position close to the rear surface using a wiring harness, a relay unit 2500 is provided in the printing module 2000.

[0036] Reference Figures 2 to 8 The arrangement of the wire harness according to the present exemplary embodiment is described. Figure 32 is a cross-sectional view showing a state in which the conveying path in the conveying unit 2400 is opened before image formation.

[0037] like Figure 3 As shown in , before image formation, the conveying unit 2400 includes a conveying guide 2414 and a conveying unit 2410, and the conveying guide 2414 and the conveying unit 2410 form a conveying path. In the present exemplary embodiment, the conveying guide 2414 is provided together with the conveying unit 2410 in the housing 2100 between a front surface frame 2100A (serving as a first frame provided at the front (front side)) and a rear surface frame 2100B (serving as a second frame provided at the rear (rear side)), and forms a conveying path through which the sheet S passes in a direction (first direction) intersecting with the front-rear direction (second direction). The conveying unit 2410 includes a conveying roller 2412 that rotates to convey the sheet S, and the conveying roller 2412 as a rotating member is driven by a driving motor 2202 (see Figure 2 ) is driven to rotate.

[0038] When a sheet S is blocked in the conveying path formed by the conveying guide 2414 and the conveying unit 2410, the sheet S is blocked by the plate 2700 (see Figure 6 ) detects a jam of the sheets S based on a signal from a detection sensor (not shown). In the case where a jam of the sheets S is detected, the user exposes the conveying path to perform a jam process to remove the sheets S remaining in the conveying path.

[0039] In the present exemplary embodiment, the user pulls down the conveying unit 2410 to expose the conveying path to remove the sheet S from the conveying path. In order to enable the user to do this, the conveying unit 2410 is configured so that the front portion of the conveying unit 2410 can rotate up and down relative to the conveying guide 2414 with the rotation axis 2413 as the rotation center, and the rotation axis 2413 is provided at a position close to the rear surface frame 2100B, which is located at a position close to the rear surface of the housing 2100. In addition, a rotation space 2900 (first space) is left below the conveying unit 2400 before image formation in the housing 2100, and the conveying unit 2410 can be rotated to a position where the sheet S can be removed. The rotation space 2900 is a rotation area in which the conveying unit 2410 can rotate.

[0040] The conveying unit 2410 as the second member is provided to be movable relative to the conveying guide 2414 between a conveying position (first position) in which the sheet S can be conveyed by the conveying roller 2412 and a separation position (second position) in which the conveying unit 2410 is separated from the conveying guide 2414 to open a conveying path through which the sheet S passes, and the sheet S cannot be conveyed by the conveying roller 2412. The conveying guide 2414 as the first member is arranged to form, together with the conveying unit 2410, a conveying path through which the sheet S passes. With the conveying unit 2410 in the separation position, the user can remove the sheet S remaining on the conveying unit 2410.

[0041] Figure 4 2 is a perspective view showing a state in which the conveying path in the conveying unit 2400 is opened before image formation. Figure 4 As shown in FIG. 2 , a lever 2420 having a locking function is provided in front of the conveying unit 2410 , and a user can unlock and rotate the conveying unit 2410 by operating the lever 2420 .

[0042] Figure 5 25 is a perspective view showing the relay unit 2500 and the wiring harness 2530. Figure 5 As shown in , the relay unit 2500 includes a connector base 2510 and a harness holding unit 2511. The relay unit 2500 is arranged closer to the front surface frame 2100A than the rear surface frame 2100B. A plurality of relay connectors 2533 are provided on the connector base 2510 serving as an arrangement base. The harness of the electrical component and the harness of the board can be inserted into or removed from the relay connector 2533. According to the present exemplary embodiment, as an example, the harness 2532 and the harness 2530 are both inserted into the relay connector 2533, and the harness 2532 is connected to the drive motor 2202 (see FIG. 2 ) serving as the first electrical component. Figure 2 ) or a first wiring harness for a detection sensor (not shown), the wiring harness 2530 is connected to a board 2700 (see Figure 6 Therefore, the driving motor 2202, the detection sensor, etc. of the pre-image formation conveying unit 2400 are electrically connected to the board 2700 through the relay unit 2500.

[0043] The connector base 2510 is fixed to the front of the harness holding unit 2511, and the harness holding unit 2511 is fixed to the partition plate 2103. The harness holding unit 2511 holds the harness 2530 connected to the plate 2700 while guiding the harness 2530 from the rear to the front of the housing 2100. It is desirable that the harness holding unit 2511 includes a groove portion for mounting the harness 2530 and a harness clamp for holding the harness 2530 so as to guide the harness 2530 introduced into the housing 2100 through the through hole 2102 formed in the rear side plate 2101 to the connector base 2510.

[0044] The harness holding unit 2511 holds the tube bundle 2800 in a similar manner to the harness 2530, and the tube bundle 2800 is aligned with the harness 2530 and introduced into the housing 2100 through the through hole 2102. The tube bundle 2800 is a bundle of a plurality of tubes connected to the head maintenance unit 2600, the plurality of tubes being used for a plurality of colors of ink, respectively. The tube bundle 2800 is provided to convey unnecessary ink from the head maintenance unit 2600 to a waste ink tank (not shown) provided at a position close to the rear surface.

[0045] like Figure 3 and Figure 4 As shown in FIG. 2 , the relay unit 2500 includes a connector cover 2520 that detachably covers the connector base 2510. The connector cover 2520 as a cover member is provided to prevent the conveying unit 2410 from contacting and damaging the relay connector 2533, the wire harness 2530, and the tube bundle 2800 on the connector base 2510 when performing a process of clearing a jam of the sheet S.

[0046] According to the present exemplary embodiment, for example, in the case where the conveying unit 2410 rotates 15 degrees, as shown in FIG. Figure 3 , the conveying unit 2410 abuts against the adjusting unit 2104 provided on the partition 2103, thereby adjusting the rotation of the conveying unit 2410. The adjusting unit 2104 protrudes from the partition 2103, so that when the conveying unit 2410 rotates 15 degrees, a gap is formed between the lower surface of the conveying unit 2410 and the connector cover 2520. With this configuration, the conveying unit 2410 does not contact the connector cover 2520, so that the conveying unit 2410 and the connector cover 2520 can be prevented from being damaged due to contact.

[0047] The connector base 2510 is disposed on the harness holding unit 2511 so that the front portion of the connector base 2510 provided with the relay connector 2533 is lower than the rear portion of the connector base 2510, as shown in FIG. Figure 3As shown in . In one embodiment, the connector base 2510 may include an inclined portion having a first edge and a second edge, the distance from the front surface frame 2100A to the first edge in the front-rear direction is less than the distance from the front surface frame 2100A to the second edge in the front-rear direction, and in the vertical direction, the first edge is lower than the second edge. With this configuration, sufficient working space is left between the connector base 2510 and the lower surface of the conveying unit 2410 so that the user can insert the wire harnesses 2532 and 2530 into and remove them from the relay connector 2533. In addition, for the user observing the relay unit 2500, the visibility of the relay connector 2533 is improved, which results in the user's operability of inserting the wire harnesses 2532 and 2530 into and removing them from the relay connector 2533 being improved.

[0048] In this exemplary embodiment, Figure 3 As shown in , the harness 2530 is arranged in the space 2910 (second space) along the front-to-rear direction from the back to the front of the housing 2100. The space 2910 (second space) is located on the side of the rotating space 2900 (first space) away from the conveying unit 2410 in the separation position, and the rotating space 2900 (first space) is a space left below the conveying unit 2400 before image formation for rotating the conveying unit 2410. The relay unit 2500 is arranged in the space 2910. The rotating space 2900 and the space 2910 are connected to each other. On the contrary, the partition 2103 located below the conveying unit 2410 separates the space including the rotating space 2900 and the space 2910 from other spaces in the housing 2100. The conveying unit 2400 before image formation can move between the conveying position and the separation position through the rotating space 2900. In another aspect, the rotating space 2900 can define the moving trajectory of the conveying unit 2400 when it moves between two positions before image formation. The harness 2530 is disposed in the space 2910 and is located on a first side (lower side) of the separation position. The delivery position is disposed on a second side (upper side) of the separation position opposite to the first side.

[0049] like Figure 5 As shown in FIG, the harness 2530 connected to the relay connector 2533 on the connector base 2510 is held by the harness holding unit 2511 and is routed to the plate 2700 disposed at a position close to the rear surface through the through hole 2102 of the rear side plate 2101. Figure 6 As shown in , board 2700 is set at a position (second side) close to the rear surface frame 2100B of the printing module 2000, and the wiring harness 2530 to be connected to board 2700 passes through the through hole 2102 on the rear side plate 2101, and then branches and is connected to each board 2700.

[0050] like Figure 5As shown in FIG. 2 , the harness 2532 connected to the relay connector 2533 on the connector base 2510 is wired in the left-right direction (the conveying direction of the sheet S) at a position close to the front surface. This is because the drive motor 2202 (see FIG. 24 ) of the conveying unit 2400 before image formation is connected to the relay connector 2533 on the connector base 2510. Figure 2 ) or a detection sensor (not shown) connected to the wiring harness 2532, such as Figure 7 and Figure 8 As shown in , it is pulled out to a position (first side) close to the front surface frame 2100A of the printing module 2000 through the through holes 2401 formed in the left and right parts of the front side plate 2140, respectively. In addition, this is because the connector cover 2520 is attached in a state where the wiring harness 2532 is connected to the relay connector 2533.

[0051] like Figure 8 As shown in FIG. 2 , it is desirable to hold the wire harness 2532 by a plurality of wire harness clips 2550. The plurality of wire harness clips 2550 form a path for routing the wire harness 2532. Figure 8 As shown in FIG. 2 , the harness 2531 connected to the motor 2203 of the printing belt unit 2200 is pulled out from the through hole 2201 formed in the front side plate to a position close to the front surface of the printing module 2000 and connected to the relay connector 2533. The harness 2531 can be held and routed by a harness clip 2551.

[0052] As described above, according to the present exemplary embodiment, the wire harness 2530 is disposed in the space 2910 below the conveying unit 2410. The relay unit 2500 that relays the wire harness 2530 to the wire harness 2532 may be disposed in the space 2910. The size of the space 2910 may be changed in the up-down direction (third direction) in which the conveying unit 2410 rotates according to the rotation space 2900 reserved for the conveying unit 2410 in the housing 2100. The size of the rotation space 2900 for the conveying unit 2410 may be adjusted within a range that allows the sheet S to be removed from the conveying path when the printing module 2000 is assembled. Therefore, a portion of the rotation space 2900 for the rotation of the conveying unit 2410 preset in the housing 2100 may also be used as the space 2910 for disposing the wire harness 2530 and the relay unit 2500. In other words, the space within the housing 2100 is effectively utilized. Therefore, it is possible to provide a wiring harness that electrically connects an electric component disposed at a position close to the front surface and a board disposed at a position close to the rear surface without increasing the size of the image forming apparatus.

[0053] According to some embodiments, an image forming device may include an image forming unit, a conveying unit, a housing, a first electrical component, a second electrical component, and a wiring harness, wherein a rotation space is left in the housing below the conveying unit before image formation so that the conveying unit can move. The wiring harness can be routed from the rear side to the front side of the housing in the space below the conveying unit in a separated position. The size of the space left in the housing can be changed according to the rotation space of the conveying unit. The space in the housing may include a portion of the rotation space preset in the housing for the rotation of the conveying unit, which can be effectively used as a space for wiring the wiring harness. Therefore, the wiring harness can be set without increasing the size of the device.
