Embodiments for Carrying out the Invention

[0009] Hereinafter, the image forming apparatus according to the present embodiment will be described with reference to the drawings. The dimensions, materials, shapes, relative arrangements, etc. of the components described in the following embodiments are not intended to limit the scope of application of the present technology only to those, unless otherwise specifically described.

[0010] [Schematic Configuration of Image Forming Apparatus] First, the schematic configuration of the image forming apparatus 1000 will be described while referring to FIG. 1. Note that the arrows in both directions shown in FIG. 1, namely "front", "rear", "top", "bottom", "right", and "left", indicate the directions based on the image forming apparatus 1000. "Front" sometimes refers to the side where the front door FD of the image forming apparatus 1000 is installed, which is also called the front face. "Rear" sometimes refers to the back side opposite to the front door FD of the image forming apparatus 1000, which is also called the back. Also, "top" refers to the upper side in the vertical direction of the image forming apparatus 1000, and "bottom" refers to the lower side in the vertical direction of the image forming apparatus 1000. Furthermore, "right" refers to the right side when the image forming apparatus 1000 is viewed from the front door FD side, and "left" refers to the left side when the image forming apparatus 1000 is viewed from the front door FD side.

[0011] As shown in FIG. 1, the image forming apparatus 1000 includes a printer 400 and an image reading unit 300. The image reading unit 300 disposed above the printer 400 includes, in detail, a reading unit 301 and an ADF (Auto Document Feeder) 302, and optically scans a document to read image information. A document is a sheet such as paper and envelopes, a plastic film such as an overhead projector sheet (OHT), or a sheet such as cloth. The image information converted into an electrical signal by the image reading unit 300 is transferred to an image processing controller 26 (see FIG. 3) provided in the printer 400.

[0012] As shown in FIGS. 1 and 2, the printer 400 has a printer main body 1, an optional feeder 100 connected to the lower part of the printer main body 1, and an optional large-capacity feed deck 200 connected to the lower part of the feeder 100. Note that the large-capacity feed deck 200 can also be connected to the lower part of the printer main body 1 instead of the lower part of the feeder 100.

[0013] The printer body 1 includes an image forming unit 33 for forming an image on a sheet, which is a recording medium; a fixing unit 23; a pair of discharge rollers 24; and a sheet feeding device 34 for feeding the sheet S to the image forming unit 33. The sheet feeding device 34 includes a cassette 2 capable of storing the sheet S and a feeding unit 3. The feeding unit 3 includes a pickup roller 3a for feeding the sheet S stored in the cassette 2, and a pair of separation rollers 3b for separating the sheet S fed by the pickup roller 3a into individual sheets.

[0014] Similarly, the feeder 100 has a cassette 2 capable of storing sheets and a feeding unit 3 that feeds the sheets stored in the cassette 2. Furthermore, the feeder 100 has a pair of intermediate transport rollers 11 that transport the sheets S fed by the feeding unit toward the printer body 1. The large-capacity feeding deck 200 has a feeding deck 201, a feeding unit 3, and a pair of intermediate transport rollers 11. The feeding deck 201 can accommodate more sheets S than the cassette 2, for example, it can accommodate about 2000 sheets S.

[0015] The image forming unit 33 comprises four process cartridges 6Y, 6M, 6C, and 6K, each forming toner images of four colors: yellow (Y), magenta (M), cyan (C), and black (K); a scanner unit 12; and an intermediate transfer unit 15. The process cartridges 6Y, 6M, 6C, and 6K are detachable from the housing of the printer body 1. The four process cartridges 6Y, 6M, 6C, and 6K have the same configuration except for the color of the image they form. Therefore, only the configuration and image forming process of process cartridge 6Y will be described, and the descriptions of process cartridges 6M, 6C, and 6K will be omitted.

[0016] The process cartridge 6Y includes a photosensitive drum 7 as an image carrier, a charging roller 8, a developing roller 9, and a cleaner 10. The photosensitive drum 7 is constructed by coating the outer circumference of an aluminum cylinder with an organic photoconductive layer and is rotated by a drive motor (not shown). The scanner unit 12 is located below the process cartridges 6Y, 6M, 6C, and 6K.

[0017] The intermediate transfer unit 15 is positioned above the process cartridges 6Y, 6M, 6C, and 6K and has an intermediate transfer belt 17 that is wound around the drive roller 16 and tension roller 14, etc. Inside the intermediate transfer belt 17, primary transfer rollers 18Y, 18M, 18C, and 18K are provided.

[0018] On the opposite side of the drive roller 16, across the intermediate transfer belt 17, is a secondary transfer roller 20 that forms a secondary transfer nip T2 with the intermediate transfer belt 17. Also, on the opposite side of the tension roller 14, across the intermediate transfer belt 17, is a cleaning unit 21. Above the intermediate transfer unit 15 is a high-voltage power supply board 13, which serves as a power supply board that generates the voltage applied to the charging roller 8, developing roller 9, primary transfer rollers 18Y, 18M, 18C, 18K, and secondary transfer roller 20, etc. Furthermore, in the vertical direction, between the high-voltage power supply board 13 and the sheet tray 25 is a toner recovery container 22 that contains the toner removed from the intermediate transfer belt 17 by the cleaning unit 21. The fixing device 23 includes a heating unit 23a having a heat source such as a heater, and a pressure roller 23b that forms a fixing nip together with the heating unit 23a.

[0019] Next, the image forming operation of the image forming apparatus 1000 configured in this way will be described. When an image signal is input to the scanner unit 12 from a personal computer (not shown) or an image reading unit 300, the scanner unit 12 irradiates a laser beam corresponding to the image signal onto the photosensitive drum 7 of the process cartridge 6Y.

[0020] At this time, the surface of the photosensitive drum 7 is uniformly charged to a predetermined polarity and potential by the charging roller 8, and an electrostatic latent image is formed on the surface when laser light is irradiated from the scanner unit 12. The electrostatic latent image formed on the photosensitive drum 7 is developed by the developing roller 9, and a yellow (Y) toner image is formed on the photosensitive drum 7.

[0021] Similarly, laser light from the scanner unit 12 is shone onto each photosensitive drum of process cartridges 6M, 6C, and 6K, forming magenta (M), cyan (C), and black (K) toner images on each photosensitive drum. The toner images of each color formed on each photosensitive drum are transferred to the intermediate transfer belt 17 by the primary transfer rollers 18Y, 18M, 18C, and 18K, and then transported to the secondary transfer roller 20 by the intermediate transfer belt 17, which is rotated by the drive roller 16. Any toner remaining on the photosensitive drum 7 is removed by the cleaner 10. The image formation process for each color is performed at a timing that overlaps with the upstream toner image that has been primary transferred onto the intermediate transfer belt 17.

[0022] In parallel with this image formation process, a sheet S is fed from the sheet feeding device 34, feeder 100, or high-capacity feeding deck 200 of the printer body 1. The sheet S is then transported to the registration roller pair 5, where it strikes the nip of the stopped registration roller pair 5, correcting any skew.

[0023] The registration roller pair 5 transports the sheet S in accordance with the image transfer timing, and the full-color toner image on the intermediate transfer belt 17 is transferred to the sheet S at the secondary transfer nip T2 by the secondary transfer bias applied to the secondary transfer roller 20. The toner remaining on the intermediate transfer belt 17 is transported to the toner collection container 22 by the cleaning unit 21. The sheet S on which the toner image has been transferred is subjected to heat and pressure in the fuser unit 23, and the toner is melted and fixed (fixed). The sheet that has passed through the fuser unit 23 is discharged to the sheet tray 25 by the discharge roller pair 24.

[0024] [Configuration of the back of the printer body] Next, the configuration of the rear of the printer body 1 will be explained using Figure 3. Figure 3 is a rear view showing the printer body 1 with the outer cover removed. As shown in Figure 3, the rear of the printer body 1 is equipped with an image processing controller 26, a controller board 27 as a control board, and a power supply device 28. The image processing controller 26 processes signals received from an input device such as a personal computer and instructs the controller board 27 to perform a print job. The controller board 27 receives the print job from the image processing controller 26 and controls the operation of each part of the printer 400 (see Figure 1) to perform the print process. The power supply device 28 is connected to the high-voltage power supply board 13, the image processing controller 26, the controller board 27, and each part of the image forming apparatus 1000 by metal bundles and supplies power to each part of the image forming apparatus 1000 (see Figure 1). The power supply device 28 is also connected to the feeder 100 and the large-capacity feed deck 200 by metal bundles and supplies power to them.

[0025] [Description of each unit] Next, the configuration of each unit of the printer body 1 will be described. Figure 4(a) is a perspective view showing the printer body 1 with the jam handling cover 70 open, and Figure 4(b) is a side view showing the printer body 1 with the jam handling cover 70 open. The printer body 1 has a plurality of transport units capable of transporting sheets S. Specifically, the printer body 1 has a plurality of transport units, as shown in Figures 4(a) and (b), a feeding unit 30, a registration unit 40, a secondary transfer unit 50, and an ejection unit 60.

[0026] On the right side of the printer body 1, there is a jam handling cover 70 that is supported so as to be openable and closable around a pivot axis 70a relative to the device body 1A of the printer body 1. The pivot axis 70a extends in the front-rear direction. The jam handling cover 70, acting as an opening and closing cover, opens relative to the device body 1A, exposing the opening 35 of the device body 1A. The jam handling cover 70 also has a manual feed tray 4 on which sheets are loaded, and a double-sided transport path (not shown) through which sheets pass when double-sided printing is performed to form images on both sides of the sheet.

[0027] The aforementioned feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60 are detachable from the device body 1A through the opening 35. In this embodiment, the device body 1A refers to the part of the printer body 1 excluding openable and closable covers such as the jam handling cover 70.

[0028] As shown in Figure 11(b), the feeding unit 30 includes a feeding section 3 and an intermediate transport roller pair 11. The feeding unit 30 also includes a flag member 36 and a tip detection sensor 31. The flag member 36 is rotatable about the rotation axis 36c of one of the rollers of the intermediate transport roller pair 11 and has a flag section 36a and a light-shielding section 36b. The flag section 36a is positioned to protrude into the transport path when the flag member 36 is in a standby position.

[0029] When the sheet S fed by the feeding unit 3 presses against the flag portion 36a, the flag member 36 rotates around the rotation axis 36c, and the light-shielding portion 36b blocks the optical path of the tip detection sensor 31. As a result, the tip detection sensor 31 can detect the tip of the fed sheet S.

[0030] As shown in Figure 8(b), the registration unit 40 is a unit including a pair of registration rollers 5, and comprises a flag member 45, a registration sensor 41, and an electromagnetic clutch 42. Similar to the flag member 36 described above, the flag member 45 is pressed against the sheet S being transported, thereby blocking the optical path of the registration sensor 41. This allows the registration sensor 41 to detect the leading edge of the sheet S being transported. Based on the detection result of the registration sensor 41, the electromagnetic clutch 42 connects and disconnects the drive to the pair of registration rollers 5, causing the pair of registration rollers 5 to rotate or stop.

[0031] As shown in Figure 5(a), the secondary transfer unit 50 includes a flag member 52 that can rotate around a pivot axis 52a and a loop sensor 51. The flag member 52 has a contact portion 52b that contacts the surface of the sheet between the secondary transfer nip T2 and the fixing device 23. Since the contact portion 52b follows the surface of the sheet, the flag member 52 rotates around the pivot axis 52a according to the amount of loop formed in the sheet. As the flag member 52 rotates, the loop sensor 51 is turned ON or OFF, and the sheet transport speed at the secondary transfer nip T2 or the fixing nip of the fixing device 23 is controlled based on the signal from the loop sensor 51. This controls the amount of loop in the sheet between the secondary transfer nip T2 and the fixing device 23 to a predetermined amount.

[0032] As shown in Figure 14, the discharge unit 60 is a unit that includes a pair of discharge rollers 24 and an inverting flapper (not shown) that switches whether to discharge the sheet S to the sheet tray 25 or to transport it to a double-sided inverting transport path (not shown). The discharge unit 60 also has an electromagnetic solenoid (not shown) that switches the position of the inverting flapper and a discharge sensor (not shown) that detects the leading edge of the sheet.

[0033] [Intermediate board] Next, the relay board 80, which is provided on the main body 1A of the printer body 1 and electrically connected to the controller board 27, will be described using Figures 3 to 4(b). The main body 1A has a main frame 90 including a first side plate 91 and a second side plate 92. The first side plate 91 and the second side plate 92 are formed in the shape of plates that extend in the left-right and up-down directions, respectively, and are positioned at different locations in the front-rear direction. That is, the first side plate 91 and the second side plate 92 extend along the attachment and detachment directions of the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60, which will be described later. The second side plate 92 is positioned behind the first side plate 91 so as to create a space SP between it and the first side plate 91.

[0034] Furthermore, the image processing controller 26, controller board 27, and power supply device 28 described above are located behind the second side plate 92. As shown in Figure 4(b), a hole 90a is formed in the main frame 90, and a support member 82 is fixed to the hole 90a. The relay board 80 is fixed to the support member 82 in an upright position in the vertical direction. That is, the relay board 80 is positioned along a virtual plane whose board surface extends in the front-rear and up-down directions. The hole 90a, support member 82, and relay board 80 are located behind the second side plate 92.

[0035] Furthermore, as shown in Figures 3 and 4(b), the relay board 80 has a first surface 81 and a second surface 84 that extend in the front-to-back and up-and-down directions, respectively. In other words, the first surface and the second surface 84 extend along the vertical direction. The first surface 81 is positioned to face the rear and to face the outside of the printer body 1 through the opening 35. In other words, the first surface 81 is provided to face the jam handling cover 70 when it is closed relative to the device body 1A. The second surface 84 is positioned on the opposite side of the first surface 81, facing forward and to face the inside of the printer body 1.

[0036] The first surface 81 of the relay board 80 is provided with multiple connectors 85, which serve as second connectors. These multiple connectors 85 are connected via metal bundles to sensors, electromagnetic clutches, electromagnetic solenoids, etc., of the aforementioned feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60. The second surface 84 of the relay board 80 is provided with various connectors soldered to it, as well as an FFC connector 87 that is connected to the controller board 27 via a flexible flat cable (hereinafter referred to as FFC) 86 (see Figure 3) which serves as a signal line. The FFC connector 87 constitutes a third connector.

[0037] Furthermore, as shown in Figure 4(a), the relay board 80 is covered by a cover member 83 supported by the main frame 90, so that even if the jam handling cover 70 is opened, the user cannot touch the multiple connectors 85 installed on the first surface 81. This prevents the static electricity from flowing to the controller board 27 via the FFC connector 87 if the user's hand, which is charged with static electricity, touches the multiple connectors 85, and causing the controller board 27 to malfunction.

[0038] [Replacement procedure for each unit] Next, using Figures 4(a) to 16, the replacement procedure for a service technician when replacing multiple transport units, namely the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60, will be explained. First, as shown in Figure 4(a), the service technician opens the jam processing cover 70 relative to the main body 1A, exposing the opening 35 on the right side of the main body 1A.

[0039] Next, the service technician removes the cover member 83 covering the relay board 80 from the main frame 90, as shown in Figures 4(a) and 4(b). This exposes the multiple connectors 85 provided on the first surface 81 of the relay board 80 through the opening 35. That is, at least the first surface 81 of the relay board 80 and some of the multiple connectors 85 are positioned to overlap the opening 35 when viewed in the front-to-back direction. The replacement procedure for each unit will be described below in order.

[0040] [Procedure for replacing the secondary transfer unit] As shown in Figure 5(b), the secondary transfer unit 50 has support shafts 51a and 51b, which extend parallel to the rotation axis of the secondary transfer roller 20. As shown in Figure 6, the support shafts 51a and 51b are engaged with engagement holes (not shown) of the registration unit 40 and are rotatably supported by the registration unit 40 around the support shafts 51a and 51b.

[0041] The engagement hole into which the support shaft 51a engages is formed in a cylindrical shape, and the engagement hole into which the support shaft 51b engages has a substantially U-shape with one side (for example, the top) open. The secondary transfer unit 50 is also biased forward by a spring (not shown) while supported by the registration unit 40. As a result, the secondary transfer unit 50 is attached to the registration unit 40 in a position in the front-rear direction. When the jam processing cover 70 is closed, the secondary transfer unit 50 is fixed to the intermediate transfer unit 15 by locking members 50L, 50L attached to the main frame 90 so that the secondary transfer roller 20 is in contact with it.

[0042] When the jam processing cover 70 is opened, the secondary transfer unit 50 rotates around the support shafts 51a and 51b in a direction away from the intermediate transfer unit 15, in conjunction with the opening of the jam processing cover 70. Then, as shown in Figures 4(b) and 5(b), the service technician disconnects the connector 50a, which serves as the first connector of the secondary transfer unit 50, from the connector 85 of the relay board 80, and removes the bundle of wires routed around the support member 82. Note that the connector 50a is connected to, for example, the loop sensor 51 via the bundle of wires.

[0043] The service technician pushes the secondary transfer unit 50 backward against a spring (not shown) that biases it forward. This allows the support shaft 51a to be removed from the cylindrical engagement hole. In this state, by lifting the secondary transfer unit 50 upward, the support shaft 51b is removed from the substantially U-shaped engagement hole, and the secondary transfer unit 50 can be removed in the removal direction DD through the opening 35, as shown in Figure 7. The secondary transfer unit 50 can be attached to the device body 1A by performing the above steps in reverse order. In this embodiment, the removal direction DD is the direction aligned to the right. [Registration Unit Replacement Procedure]

[0044] As shown in Figures 8(b) and 9, the registration unit 40 has a positioning boss 43 and four screw fastening parts 42a, 42b, 42c, and 42d. The positioning boss 43 engages with the main frame 90 and positions the registration unit 40 relative to the main frame 90 in the front-rear and up-down directions. In this state, the registration unit 40 is fixed to the main frame 90 by the screw fastening parts 42a, 42b, 42c, and 42d being fixed to the main frame 90 by screws.

[0045] When removing the registration unit 40 from the main frame 90, the service technician disconnects the connectors 40a and 40b of the registration unit 40 from the connector 85 of the relay board 80, as shown in Figures 4(b) and 8(a) to 9. The service technician then removes the bundle of wires routed around the support member 82 and removes the four screws fastened to the screw fastening portions 42a, 42b, 42c, and 42d. Note that the connectors 40a and 40b, which act as the first connectors, are connected to the registration sensor 41, for example, via the bundle of wires.

[0046] Then, as shown in Figure 10, the service technician can remove the registration unit 40 from the main frame 90 by pulling it out in the removal direction DD, thereby removing the registration unit 40 through the opening 35. The registration unit 40 can be attached to the main frame 90 by performing the above steps in reverse order.

[0047] [Procedure for replacing the feed unit] Figure 11(a) is a perspective view showing the feeding unit 30, and Figure 11(b) is a cross-sectional view showing the 11B-11B section of Figure 11(a). As shown in Figure 11(a), the feeding unit 30 has positioning bosses 31a, 31b, and 31c, and a screw fastening portion 31d. When the feeding unit 30 is attached to the main frame 90, the positioning bosses 31c and the screw fastening portion 31d are located at the front of the feeding unit 30, and the positioning bosses 31a and 31b are located at the rear of the feeding unit 30. The positioning bosses 31a and 31b extend parallel to the rotation axis of the intermediate conveying roller pair 11.

[0048] As shown in Figures 11(a) and 12, the positioning bosses 31a and 31b of the feeding unit 30 engage with the second side plate 92 of the main frame 90. This positions the feeding unit 30 relative to the main frame 90 in the vertical and horizontal directions. Additionally, the positioning boss 31c of the feeding unit 30 engages with the first side plate 91 of the main frame 90. This positions the feeding unit 30 relative to the main frame 90 in the front-rear direction. In this state, the feeding unit 30 is fixed to the main frame 90 by the screw fastening portion 31d being secured to the main frame 90 with screws.

[0049] When removing the feeding unit 30 from the main frame 90, the service technician disconnects the connector 30a of the feeding unit 30 from the connector 85 of the relay board 80, as shown in Figures 4(b) and 11(a) to 12. The service technician then removes the bundle of wires routed around the support member 82 and removes the screws fastened to the screw fastening portion 31d. The connector 30a, as the first connector, is connected to, for example, the tip detection sensor 31 via a bundle of wires.

[0050] Next, the service technician pulls the positioning boss 31c out of the positioning hole in the first side plate 91 by rotating the positioning boss 31c towards the rear center of the feeding unit 30. Then, the service technician moves the feeding unit 30 forward to remove the positioning bosses 31a and 31b from the second side plate 92.

[0051] Then, as shown in Figure 13, the service technician can remove the feeding unit 30 from the main frame 90 by pulling it out in the removal direction DD, thereby removing the feeding unit 30 through the opening 35. The feeding unit 30 can be attached to the main frame 90 by performing the above steps in reverse order.

[0052] [Procedure for replacing the discharge unit] As shown in Figure 14, the discharge unit 60 has a positioning portion 61a (not shown) and a positioning portion 61b that extend to the left. The discharge unit 60 is positioned in the vertical and horizontal directions relative to the main frame 90 by the engagement of the positioning portions 61a and 61b with the main frame 90. The discharge unit 60 is then fixed to the main frame 90 by four screw fastening portions 62a, 62b, 62c, and 62d which are fixed to the main frame 90 by screws, as shown in Figure 15.

[0053] When removing the discharge unit 60 from the main frame 90, the service technician disconnects the wire bundle of the discharge unit 60 from the connector 85 of the relay board 80, as shown in Figures 4(b), 14, and 15. Next, the service technician removes the four screws fastened to the screw fastening portions 62a, 62b, 62c, and 62d.

[0054] Then, as shown in Figure 16, the service technician can remove the discharge unit 60 from the main frame 90 by pulling it out in the removal direction DD, thereby removing the discharge unit 60 through the opening 35. The discharge unit 60 can be attached to the main frame 90 by performing the above steps in reverse order.

[0055] As described above, the multiple transport units, including the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60, can be accessed by opening the jam processing cover 70. Furthermore, the relay substrate 80 can be accessed by opening the jam processing cover 70 and the cover member 83.

[0056] Multiple connectors 85 are provided on the first surface 81 of the relay board 80, and the first surface 81 and the multiple connectors 85 are positioned to face the opening 35. In other words, service personnel can easily access the multiple connectors 85. As a result, the multiple connectors 85 and the connectors provided on the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60 can be easily connected and disconnected, improving maintainability.

[0057] Furthermore, the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60 are arranged in the space SP between the first side plate 91 and the second side plate 92 of the main frame 90. On the other hand, the relay substrate 80 is arranged on the rear side of the second side plate 91, that is, on the opposite side from the first side plate 91 to the second side plate 92. In this embodiment, the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60 are attached and detached parallel to the removal direction DD, which is to the right. Therefore, the relay substrate 80 is positioned so as not to interfere with the attachment and detachment trajectory when attaching and detaching the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60 to and from the main frame 90. As a result, the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60 can be easily attached and detached to and from the main frame 90, improving maintainability.

[0058] Furthermore, the fastening of screws to the main frame 90 of the feeding unit 30, registration unit 40, secondary transfer unit 50, and discharge unit 60, as well as the attachment and detachment of the units, can be completed solely from the side of the opening 35. As a result, there is no need to remove any other exterior parts besides the jam processing cover 70, improving maintainability.

[0059] Furthermore, the relay board 80 has multiple connectors 85 on its first surface 81 and an FFC connector 87 on its second surface 84, which is opposite to the first surface 81. The FFC connector 87 is connected to the controller board 27 by an FFC 86. By providing connectors on both sides of the relay board 80 in this way, the wiring to each transport unit and the controller board 27 can be simplified, and space can be saved. In addition, the first surface 81 and the second surface 84 extend along the vertical direction, and the first surface 81 can be made wider when accessing it from the opening 35. As a result, many connectors can be provided on the first surface 81, and one relay board 80 can be connected to multiple transport units.

[0060] The above configuration assumes the use of a double-sided board as the relay board 80, which allows elements to be mounted on both sides of the board. However, a less expensive single-sided board may also be used. If a single-sided board is used, multiple connectors 85 and FFC connectors 87 will be provided on the first side 81. Compared to the configuration using a double-sided board, this configuration results in more complex wiring, but reduces the cost of the board.

[0061] [Arrangement of high-voltage power supply board, toner recovery container, and intermediate transfer unit] Next, the arrangement of the high-voltage power supply board 13, toner recovery container 22, and intermediate transfer unit 15 will be described in detail using Figures 2 and 17 to 19. Figure 17 is a perspective view showing the image forming apparatus 1000 with the front door FD open and the left side exterior of the printer body 1 removed. Figure 18 is a top view of the printer body 1 viewed vertically. Figure 19 is a top view of the image forming apparatus 1000 viewed vertically. Note that the feeder 100 and the large-capacity feeding deck 200 are omitted in Figure 17. Also, the sheet tray 25 and cover member 13C are omitted in Figure 18.

[0062] As shown in Figures 2 and 17, the main frame 90 has a metal stay 95 connecting the first side plate 91 and the second side plate 92, and the metal stay 95 is positioned above the intermediate transfer unit 15. The high-voltage power supply board 13 is positioned above the metal stay 95. By positioning the metal stay 95 between the intermediate transfer unit 15 and the high-voltage power supply board 13, it is possible to prevent the user from accidentally touching the high-voltage power supply board 13 when the process cartridge or the intermediate transfer unit 15 is detached from the main frame 90. The high-voltage power supply board 13 is positioned such that its surface is approximately parallel to the plane formed by the photosensitive drums of the four process cartridges 6Y, 6M, 6C, and 6K.

[0063] A cover member 13C is provided above the high-voltage power supply board 13 so as to cover the high-voltage power supply board 13. The cover member 13C, which acts as a power supply cover, is fixed to the main frame 90 and the high-voltage power supply board 13 with hooks or the like. Furthermore, a toner collection container 22 is positioned above the cover member 13C. The toner collection container 22 is placed on the upper surface of the cover member 13C and is movable in the front-rear direction along rails provided on the cover member 13C.

[0064] A front door FD is supported at the front of the main body 1A of the printer unit 1, allowing it to be opened and closed. Opening the front door FD opens the opening 22a at the front of the main body 1A, providing access to the process cartridges 6Y, 6M, 6C, and 6K. The process cartridges 6Y, 6M, 6C, and 6K can be attached to and detached from the main body frame 90 in the front-to-back direction. In addition, the user and service personnel can remove the toner collection container 22 from the main body frame 90 through the opening 22a. The cover member 13C covers the top of the high-voltage power supply board 13, and is configured so that the user cannot touch the high-voltage power supply board 13 even when the toner collection container 22 is removed from the main body frame 90.

[0065] A sheet tray 25 is provided at the top of the printer body 1. The sheet tray 25 has a slope 25a that inclines upward as it moves downstream in the discharge direction of the discharge roller pair 24, and a stopper surface 25b. As a result, sheets discharged into the sheet tray 25 by the discharge roller pair 24 slide down along the slope 25a and their rear ends abut against the stopper surface 25b, thus aligning them in the discharge direction. This improves the sheet stacking capacity of the sheet tray 25 and makes it easier for the user to remove the discharged sheet bundles.

[0066] Because the sheet tray 25 has an inclined surface 25a, a space is created between the sheet tray 25 and the high-voltage power supply board 13. The toner collection container 22 is positioned so that at least a portion of it is housed within this space.

[0067] Furthermore, the cleaning unit 21 provided in the intermediate transfer unit 15 is positioned near the tension roller 14. The toner remaining on the intermediate transfer belt 17 collected by the cleaning unit 21 is transported upward toward the toner collection container 22 by the toner transport unit 29. The toner transport unit 29 has a screw for transporting the toner upward and a gear for rotating the screw. The toner transport unit 29 is positioned to straddle the high-voltage power supply board 13 in the vertical direction in order to transport the toner from the intermediate transfer unit 15 to the toner collection container 22.

[0068] In Figure 18, the area where process cartridges 6Y, 6M, 6C, and 6K are located is indicated by a dashed line. At least a portion of the high-voltage power supply board 13 is positioned so as to overlap the process cartridges 6Y, 6M, 6C, and 6K when viewed from above. The high-voltage power supply board 13 is also positioned on the opposite side of the sheet transport path CP, i.e., to the left of the printer body 1.

[0069] Furthermore, as shown in Figure 19, the high-voltage power supply board 13 is provided with a screw fastening portion 13b, which serves as a fixing portion and is located on the left front of the printer body 1. The high-voltage power supply board 13 is fixed to the main body frame 90 by the screw fastening portion 13b being fixed to the metal stay 95 with screws, which serve as fasteners. Note that the method of fixing the high-voltage power supply board 13 to the main body frame 90 is not limited to fixing with screws. Also, the high-voltage power supply board 13 may be fixed to any part of the main body frame 90, not just the metal stay 95.

[0070] [Procedure for replacing the high-voltage power supply board] Next, the procedure for replacing the high-voltage power supply board 13 will be explained using Figures 2 and 17 to 20. First, the service technician opens the front door FD and removes the toner collection container 22 from the main frame 90. Next, the service technician removes the outer cover on the left side of the printer body 1. By removing this outer cover, the connector portion connecting the high-voltage power supply board 13 to various electrical boards (not shown) is exposed.

[0071] Next, the service technician removes the seat tray 25. The seat tray 25 is secured to the main frame 90 with screws. The service technician removes all the screws and pulls the seat tray 25 out to the left.

[0072] Next, the service technician removes the cover member 13C that covers the top of the high-voltage power supply board 13. After removing the cover member 13C, the service technician disconnects all connectors connected to each connector section of the high-voltage power supply board 13 and removes the screws fastened to the screw fastening section 13b shown in Figure 19.

[0073] In this case, as in this embodiment, a service technician may perform the replacement of the high-voltage power supply board 13 with the image reading unit 300 mounted above the printer body 1. As described above, the screw fastening portion 13b of the high-voltage power supply board 13 is located on the left front of the printer body 1. When removing the sheets discharged into the sheet tray 25, it is preferable to have space on the left front of the sheet tray 25. For this reason, in this embodiment as well, as shown in Figure 19, when the image forming apparatus 1000 is viewed from above, the left front of the printer body 1 is configured not to overlap with the image reading unit 300.

[0074] Furthermore, the screw fastening portion 13b for securing the high-voltage power supply board 13 to the metal stay 95 is positioned so as not to overlap with the image reading unit 300 when viewed from above. In other words, a workspace is provided directly above the screw fastening portion 13b for removing the screws fastened to the screw fastening portion 13b. By arranging the screw fastening portion 13b and the image reading unit 300 in this way, a service technician can access the screw fastening portion 13b without removing the image reading unit 300 from the printer body 1. In addition, because there is a workspace above the screw fastening portion 13b, the screws fastened to the screw fastening portion 13b can be easily removed, improving maintainability.

[0075] Incidentally, the rear end of the high-voltage power supply board 13 is provided with multiple contact points for applying voltage to the process cartridges 6Y, 6M, 6C, and 6K. The contact points are in contact with contact springs provided on the printer body 1, and the high-voltage power supply board 13 applies voltage to the process cartridges 6Y, 6M, 6C, and 6K via the contact springs.

[0076] The high-voltage power supply board 13 is secured by a hook located at the front of the printer body 1. The service technician releases the hook and lifts the front of the high-voltage power supply board 13 upwards. Next, the service technician moves the high-voltage power supply board 13 forward while lifting it upwards, separating the multiple contact points located at the rear of the high-voltage power supply board 13 from the contact springs located on the printer body 1. Once all the contact points on the high-voltage power supply board 13 and the contact springs on the printer body 1 are separated, the service technician moves the high-voltage power supply board 13 to the left, thereby removing it from the main frame 90. The high-voltage power supply board 13 can be attached to the main frame 90 by performing the above steps in reverse order.

[0077] As explained above, the user-replaceable toner collection container 22 can be removed in the front-to-back direction with the front door FD open. On the other hand, the high-voltage power supply board 13, which is replaced by a service technician, is located below the toner collection container 22 and is accessible from the left side, not the front, of the printer body 1. Furthermore, the high-voltage power supply board 13 can be attached and detached by moving it in the left-to-right direction relative to the printer body 1, thus clearly distinguishing it from the user-replaceable parts. In other words, the direction of attachment and detachment of the high-voltage power supply board 13 is different from the direction of attachment and detachment of the multiple transport units: the supply unit 30, the registration unit 40, the secondary transfer unit 50, and the discharge unit 60. To put it another way, the high-voltage power supply board 13 is removed from the side of the device body 1A opposite to the jam processing cover 70 side. This reduces the risk of the user accidentally accessing and touching the high-voltage power supply board 13.

[0078] <Other Embodiments> In this embodiment, the device body 1A is configured to allow access to the relay board 80 by opening a jam handling cover 70 located on its right side, but the invention is not limited to this configuration. In other words, any cover that can be opened and closed relative to the device body 1A and that allows access to the relay board 80 when opened is acceptable, and the invention is not limited to the jam handling cover 70. Furthermore, the relay board 80 is not limited to the right side of the device body 1A; it may be located on the front, back, or left side. That is, if the device is configured to allow attachment and detachment of multiple transport units from the left side, the effects of the present invention can be obtained by also locating the relay board on the left side.

[0079] Furthermore, in this embodiment, the image forming apparatus 1000 had a printer 400 and an image reading unit 300, but is not limited to this. For example, the image reading unit 300 may be omitted, and only the printer 400 may be used as the image forming apparatus. Moreover, the feeder 100 and the large-capacity feeding deck 200 may be omitted, and only the printer body 1 may be used as the image forming apparatus.

[0080] Furthermore, in this embodiment, a feeding unit 30, a registration unit 40, a secondary transfer unit 50, and a discharge unit 60 are given as examples of multiple transport units, but the embodiment is not limited to these. Any transport unit capable of transporting sheets may be used.

[0081] Furthermore, although the invention has been described using an electrophotographic printer 400 in all of the embodiments described above, the present invention is not limited thereto. For example, the present invention can also be applied to an inkjet printer that forms an image on a sheet by ejecting ink liquid from a nozzle.
