Note that the embodiments are not limited to the examples described below. Furthermore, the following explanation assumes that the sheet is made of paper.

[0010] [Example of the overall configuration of a sheet processing device] Figure 1 shows an example of the overall configuration of a sheet processing device. The following explanation will use the image forming apparatus 1 shown in the figure as an example. In the following explanation, the vertical direction will be referred to as the "Z-axis". The axis perpendicular to the Z-axis and in the direction of the shorter side of the image forming apparatus 1 will be referred to as the "X-axis". Furthermore, the axis relative to both the Z-axis and the X-axis and in the direction of the longer side of the image forming apparatus 1 will be referred to as the "Y-axis". Therefore, the X-axis and Y-axis form the "XY plane", and the Z-axis is perpendicular to the XY plane.

[0011] As shown in Figure 1, the image forming apparatus 1 is a device that has a configuration in which multiple housings are combined to form an integrated unit. Specifically, the image forming apparatus 1 has a structure in which at least the first housing and the second housing can be separated. The image forming apparatus 1 may also be a device that is assembled from three or more components.

[0012] In Figure 1, the image forming apparatus 1 is composed of three different functional blocks: the image forming unit 10, the first paper feeder 100, and the second paper feeder 200. In other words, the image forming apparatus 1 is an example of a device composed of multiple devices, each housing a predetermined function, combined to form a single integrated device. Hereinafter, a device that houses a predetermined function and can be recognized as a specific device will be referred to as a "housing." Therefore, the image forming apparatus 1 may have a configuration without the second paper feeder 200. Alternatively, the image forming apparatus 1 may have a configuration that includes additional devices to be assembled besides the image forming unit 10, the first paper feeder 100, and the second paper feeder 200.

[0013] As shown in Figure 1, the first paper feeder 100, which is one housing, is assembled to be mounted on top of the second paper feeder 200, which is another housing, in the Z-axis direction. Similarly, the image forming unit 10 is assembled to be mounted on top of the first paper feeder 100, in the Z-axis direction.

[0014] The following explanation will use an example where the first housing is an image forming machine 10. Note that when the first housing includes an image forming device, as in the case of the image forming machine 10, it often becomes heavy and difficult to assemble.

[0015] The following explanation will use an example where the second housing is the first paper feed device 100. However, the first housing and the second housing may be a combination other than the image forming unit 10 and the first paper feed device 100. In other words, the first housing and the second housing may be separated at locations other than those shown in Figure 1. Therefore, the image forming unit 10 and the first paper feed device 100 may be composed of devices other than those described in Figure 1.

[0016] The image forming machine 10 is a device equipped with an image forming unit. Specifically, the image forming machine 10 comprises a charger 13, a developer 14, a transfer unit 15, a cleaning unit 16, an optical writing device 17, and a photoreceptor 18. The photoreceptor 18 rotates in the direction indicated by the arrow.

[0017] The first paper feed device 100 includes a first paper feed cassette 101. The first paper feed cassette 101 stores paper S. The first paper feed cassette 101 also includes a first handle 101a.

[0018] A first sheet transport path 102 is formed within the first handle 101a. A first paper feed path 103 is connected to the first sheet transport path 102.

[0019] The second paper feed device 200 includes a second paper feed cassette 201. The second paper feed cassette 201 stores paper S. The second paper feed cassette 201 also includes a second handle 201a.

[0020] A second sheet transport path 202 is formed within the second handle 201a. A second paper feed path 203 is connected to the second sheet transport path 202.

[0021] The first paper feed cassette 101 and the second paper feed cassette 201 are designed to be removable.

[0022] Then, when the first paper feeder 100 and the second paper feeder 200 are assembled, the first sheet transport path 102 and the second sheet transport path 202 are connected.

[0023] The first paper feed roller 104 is installed near the entrance of the first paper feed path 103. When image forming is performed, the first paper feed roller 104 rotates to feed the paper S.

[0024] The second paper feed roller 204 is installed near the entrance of the second paper feed path 203. When image forming is performed, the second paper feed roller 204 is driven to rotate and feed the paper S.

[0025] Paper S is fed from the first paper feeder 100 through the first sheet transport path 102 and the first paper feed path 103. Meanwhile, paper S is fed from the second paper feeder 200 through the second paper feed path 203, the first sheet transport path 102, and the second sheet transport path 202. The paper S is then fed to the image forming unit 10 from the paper output slot 105.

[0026] The paper S stops when it hits the registration roller 40. Then, the registration roller 40, after timing, transports the paper S to the photoreceptor 18.

[0027] The photoreceptor 18 is charged on its surface by the charger 13. Next, the optical writing device 17 shines a laser beam L onto the photoreceptor 18. When the laser beam L is shone on the photoreceptor 18, an electrostatic latent image is formed on the photoreceptor 18. When the electrostatic latent image passes through the developer 14, toner adheres to it and it becomes a visible image. Next, the transfer unit 15 transfers the visible image onto the paper S.

[0028] After transferring the visible image, the paper S is transported to the fuser 41, which fixes the image on the paper S by applying heat and pressure. Next, the paper S is transported in the transport direction E by the transport roller 42. After that, the paper discharge roller 43 discharges the paper S.

[0029] Furthermore, the cleaning device 16 removes residual toner from the surface of the photoreceptor 18 through cleaning.

[0030] Note that the image forming apparatus 1 is not limited to the configuration described above. Therefore, the image forming apparatus 1 may include devices other than those described above.

[0031] The following description will use the assembly of the first paper feed device 100 with the image forming unit 10 mounted on it as an example. Therefore, in the following description, the first paper feed device 100 will have the image forming unit 10 mounted on the upper surface in the Z-axis direction (hereinafter referred to as the "contact surface 300"). Also, in the following description, the contact surface 300 will be the XY plane.

[0032] [Assembly example] Figure 2 shows an example of assembly. As shown in the figure, the assembly first involves mounting the image forming unit 10 onto the contact surface 300 of the first paper feed device 100.

[0033] The following explanation will use an example where the first restricting member is abutment member 112.

[0034] The first paper feed device 100 includes a stopper member 112. The following description will explain the process using an example of aligning the position of the image forming unit 10 in the Y-axis direction during assembly. In the following description, the direction in which the image forming unit 10 is first aligned during assembly will be referred to as the "first direction." Therefore, in the following description, the first direction is the Y-axis direction. However, alignment is not limited to the Y-axis direction. For example, the first direction may be the X-axis direction or any direction set arbitrarily.

[0035] The stopper member 112 is made of metal or resin. The stopper member 112 may be integrated with the first paper feed device 100, or it may be a separate part from the first paper feed device 100.

[0036] The abutment member 112 is preferably located at the end of the contact surface 300. In the example shown in Figure 2, the abutment member 112 is located at the innermost position along the Y-axis. When the abutment member 112 is located at the end of the contact surface 300 in this way, the user can easily see the abutment member 112 because it is less likely to be hidden by other devices, etc.

[0037] Therefore, when the abutment member 112 is located at the end of the contact surface 300, the user can easily see when abutting the image forming machine 10 against the abutment member 112 during assembly, making the work easier.

[0038] Furthermore, if the abutment member 112 is located at the end of the contact surface 300, it is often easier to manufacture the abutment member 112.

[0039] However, the abutment member 112 may be located at a position other than the end, as long as it is on the contact surface 300. Also, the abutment member 112 may have a shape other than that shown in Figure 2. For example, the abutment member 112 may have a shape in which a part is missing in the X-axis direction.

[0040] The following explanation will use an example where the contact plates are the first rotating plate 108 and the second rotating plate 110. Note that one or more contact plates are sufficient. The following explanation will describe a configuration in which two contact plates are provided on each side of the image forming machine 10.

[0041] The first paper feeder 100 includes a first rotation shaft 109 and a second rotation shaft 111. The first rotating plate 108 rotates around the first rotation shaft 109, that is, around the vertical axis. Similarly, the second rotating plate 110 rotates around the second rotation shaft 111, that is, around the vertical axis. Note that the first rotating plate 108 and the second rotating plate 110 are not limited to mechanisms that rotate around the vertical axis. For example, the first rotating plate 108 and the second rotating plate 110 may rotate around a first direction, which is an axis other than the vertical axis.

[0042] After the image forming machine 10 is aligned, the first rotating plate 108 and the second rotating plate 110 are closed and come into contact with the side surface of the image forming machine 10. That is, the operation in which the first rotating plate 108 rotates on the first rotation axis 109 and the second rotating plate 110 rotates on the second rotation axis 111, so that each rotates in a direction that brings them into contact with the side surface of the image forming machine 10, will be described in the following description as "closing the first rotating plate 108 and the second rotating plate 110." Also, the operation in which the first rotating plate 108 rotates on the first rotation axis 109 and the second rotating plate 110 rotates on the second rotation axis 111, so that each rotates in a direction that moves them away from the side surface of the image forming machine 10, will be described in the following description as "opening the first rotating plate 108 and the second rotating plate 110."

[0043] The first rotating plate 108 may also include a first fitting plate 108A, a second fitting plate 108B, and the like.

[0044] Furthermore, the second rotating plate 110 may also have a third fitting plate 110A, a fourth fitting plate 110B, and so on.

[0045] Assembly involves placing the image forming unit 10 on the contact surface 300. This method of placing the image forming unit 10 on the contact surface 300 before its alignment is complete is called "temporary placement." Therefore, the temporary placement state is part of the assembly process, and the user moves the image forming unit 10 on the contact surface 300 to align it.

[0046] Specifically, during assembly, the user first temporarily places the image forming machine 10. Then, the user moves the image forming machine 10 so that it abuts against the abutment member 112 in the Y-axis direction. In this way, the presence of the abutment member 112 allows the image forming machine 10 to abut against the abutment member 112, and restricts the movement of the image forming machine 10 in the Y-axis direction. Therefore, by abutting against the abutment member 112, the image forming machine 10 can be aligned in the Y-axis direction.

[0047] Since the first rotating plate 108 and the second rotating plate 110 rotate, during assembly, the user moves the first rotating plate 108 and the second rotating plate 110 so as not to obstruct the movement of the image forming machine 10, and then moves the image forming machine 10 in the X-axis direction.

[0048] Then, after the alignment in the X-axis direction is completed, when the first rotating plate 108 and the second rotating plate 110 are closed, the first rotating plate 108 and the second rotating plate 110 come into contact with the side surface. In this case, if the alignment in the X-axis direction is insufficient and the first rotating plate 108 and the second rotating plate 110 are closed, the contact plates will not close completely, or a gap will be created between the contact plates, allowing the user to recognize that the alignment in the X-axis direction is insufficient.

[0049] Alternatively, the first fitting plate 108A, the second fitting plate 108B, the third fitting plate 110A, and the fourth fitting plate 110B may be used for alignment. The first fitting plate 108A, the second fitting plate 108B, the third fitting plate 110A, and the fourth fitting plate 110B engage with the fitting groove 108AA formed in the image forming unit 10. Therefore, the user may recognize whether alignment is achieved by whether or not the first fitting plate 108A, the second fitting plate 108B, the third fitting plate 110A, and the fourth fitting plate 110B engage with the fitting groove 108AA.

[0050] [Example of assembly shown from the perspective of the XY plane] The assembly example described above will be explained from the perspective of the XY plane.

[0051] Figure 3 is a diagram (part 1) showing an example of assembly in the XY plane. Figure 3 shows the state before the image forming machine 10 is temporarily placed. As can be seen, in the state before assembly, the image forming machine 10 is not yet placed on the contact surface 300.

[0052] Figure 4 is a diagram (part 2) showing an example of the assembly in the XY plane. Compared to Figure 3, Figure 4 differs in that the image forming machine 10 is temporarily placed. The following explanation will focus on the differences, omitting redundant explanations.

[0053] In this way, the ability to temporarily place the components allows the user to reduce the time spent holding the heavy image forming machine 10 during assembly. Therefore, the user can reduce the physical strain during assembly and make the assembly of the device easier.

[0054] Furthermore, it is desirable that the image forming unit 10 has a shape that facilitates temporary placement during assembly. Specifically, it is desirable that the bottom surface of the image forming unit 10, that is, the surface that contacts the contact surface 300 during temporary placement, be flat. With this configuration, where the contact surface 300 and the image forming unit 10 are in contact on a flat surface, it is easier for the user to temporarily place the unit.

[0055] After the initial placement, the user performs the following operation to bring the image forming machine 10 into contact with the object.

[0056] Figure 5 is a diagram (part 3) showing an example of assembly in the XY plane. Compared to Figure 4, Figure 5 differs in that the image forming unit 10 is abutting against the abutment member 112.

[0057] During assembly, the user performs an operation to push in the abutment direction 500. The abutment direction 500 is the Y-axis direction. When the image forming machine 10 is pushed in the abutment direction 500, the image forming machine 10 moves toward the abutment member 112 in the Y-axis direction. Furthermore, when the image forming machine 10 continues to be pushed in the abutment direction 500 and hits the abutment member 112, the movement of the image forming machine 10 in the Y-axis direction is restricted.

[0058] Furthermore, the abutment member 112 is installed at a position where the image forming unit 10 abuts against the abutment member 112, and where the position of the paper output slot 105 and other elements are aligned in the Y-axis direction. Therefore, the user can abut the image forming unit 10 against the abutment member 112 to align it in the Y-axis direction.

[0059] On the other hand, the state shown in Figure 5 is as follows:

[0060] Figure 6 is a diagram (part 4) showing an example of assembly in the XY plane. Figure 6 shows the same state as Figure 5. Specifically, the image forming machine 10 has completed alignment in the Y-axis direction. On the other hand, the image forming machine 10 has not completed alignment in the X-axis direction. Specifically, in Figure 6, the image forming machine 10 has a deviation of 400 in the X-axis direction from the position where it is sufficiently aligned.

[0061] Thus, when attempting to close the second rotating plate 110 while there is a misalignment of 400 (as shown in the figure, when rotating it in the closing direction 501), the second rotating plate 110 and the side surface of the image forming machine 10 interfere at the interference point 401. With such an interference point 401, the second rotating plate 110 will not close, and the second rotating plate 110 will not be in contact with the side surface of the image forming machine 10 as a whole. Therefore, the user can recognize that the image forming machine 10 is not sufficiently aligned in the X-axis direction because the second rotating plate 110 does not close.

[0062] Thus, if the image forming machine 10 is sufficiently aligned in the X-axis direction, the second rotating plate 110 and other mechanical components such as the second rotating shaft 111 are installed at a position where the second rotating plate 110 contacts the side surface of the image forming machine 10.

[0063] Next, the user aligns the image forming machine 10 in the X-axis direction as follows.

[0064] Figure 7 is a diagram (part 5) showing an example of assembly in the XY plane. Figure 7 shows the same state as Figure 6. During assembly, the user aligns the parts in the X-axis direction to eliminate the misalignment of 400.

[0065] Specifically, the image forming machine 10 is pushed in the horizontal direction 502. Note that the horizontal direction 502 is the X-axis direction. When the image forming machine 10 is pushed in the horizontal direction 502, the image forming machine 10 moves in the X-axis direction. When the image forming machine 10 is sufficiently aligned in the X-axis direction through this operation, it will be in the following state.

[0066] Figure 8 is a diagram (number 6) showing an example of assembly in the XY plane. Compared to Figure 7, Figure 8 differs in that the image forming machine 10 has moved in the X-axis direction and is in a state of sufficient alignment. Therefore, Figure 8 shows a state without a misalignment of 400.

[0067] Thus, when the image forming unit 10 is sufficiently aligned in the X-axis direction, the first rotating plate 108 and the second rotating plate 110 can be closed, resulting in the following state.

[0068] Figure 9 is a diagram (number 7) showing an example of assembly in the XY plane. Figure 9 differs from Figure 8 in that the first rotating plate 108 and the second rotating plate 110 are in a closed state.

[0069] When the image forming machine 10 is properly aligned in the X-axis direction, the interference point 401 shown in Figure 6 does not occur. Therefore, when the first rotating plate 108 and the second rotating plate 110 are closed, they rotate in the closing direction 501, and the first rotating plate 108 and the second rotating plate 110 come into contact with the side surface of the image forming machine 10.

[0070] Furthermore, in the configuration shown in Figure 9, when the image forming unit 10 is properly aligned, the first fitting plate 108A, the second fitting plate 108B, the third fitting plate 110A, and the fourth fitting plate 110B align with the fitting grooves and fit together.

[0071] As described above, when the image forming unit 10 is sufficiently aligned in both the X-axis and Y-axis directions, the first rotating plate 108 and the second rotating plate 110 close, allowing the user to recognize that the alignment is sufficient. On the other hand, insufficient alignment can cause malfunctions such as paper jams at the paper output slot 105.

[0072] With the first regulating member, the user can easily align the parts in the first direction (the Y-axis direction in the above example) by abutting them. With the contact plate, the user can easily align the parts in the X-axis direction by determining whether or not the contact plate is closed. Therefore, by providing the first regulating member and the contact plate, the user can easily assemble the first and second housings.

[0073] [Second Embodiment] The image forming apparatus 1 is preferably configured to further include fixing members. The following description will illustrate an example in which the fixing members are implemented using a first fitting plate 108A and screws 60. Note that the fixing members may also be implemented using fitting plates other than the first fitting plate 108A, or the second rotating plate 110. Furthermore, there may be fixing members in multiple locations.

[0074] Figure 10 shows an example of a second embodiment. For example, as shown in the figure, the first rotating plate 108 has a shape in which the portion of the first fitting plate 108A protrudes in the Z-axis direction. A fitting groove matching the shape of the first fitting plate 108A is formed on the side surface of the image forming apparatus 10 that contacts the first rotating plate 108.

[0075] After closing and assembling the first rotating plate 108, it is desirable that the positions of the image forming unit 10 and the first paper feed device 100 be fixed by the first rotating plate 108 and the screws 60, as shown below.

[0076] Figure 11 shows an example of fastening using a fixing member. Figure 11 is a cross-sectional view of "A-A'" in Figure 10.

[0077] Screw holes for inserting screws 60 are pre-formed on the side of the image forming machine 10. Meanwhile, through holes for inserting screws 60 are pre-formed on the first rotating plate 108.

[0078] Therefore, after closing and assembling the first rotating plate 108, inserting the screw 60 from the outside of the first rotating plate 108 allows the first rotating plate 108 to be fixed in a position that contacts both the side of the image forming unit 10 and the first paper feed device 100.

[0079] As shown in Figures 10 and 11, when the first rotating plate 108 is closed, it is large and tall enough to straddle the side of the image forming unit 10 and the first paper feed device 100. Therefore, when the screw 60 is inserted, the image forming unit 10 and the first paper feed device 100 are prevented from moving by the first rotating plate 108 and become immobile. In this way, by fixing them with a fixing member, the positions of the image forming unit 10 and the first paper feed device 100 can be maintained even when external forces are applied.

[0080] The image forming unit 10 and the first paper feed device 100 are heavy and shaped in such a way that they move when pushed after being temporarily placed. Therefore, even after assembly, their positions may shift if they are not fixed in place. By fixing them with a fixing member, it is possible to prevent the relative positions of the image forming unit 10 and the first paper feed device 100 from shifting after assembly.

[0081] Note that the fixing member is not limited to the configuration described above. For example, the first rotating plate 108 may have claws 61, etc. Also, the fixing member may be implemented with mechanical components such as magnets or nails.

[0082] [Third Embodiment] Figure 12 shows an example of the overall configuration of the sheet processing apparatus according to the third embodiment. Compared to the first embodiment, the third embodiment differs in that it has a configuration that connects the first connecting member and the second connecting member.

[0083] The following explanation will use an example where the first connecting member is a drawer connector 70. The drawer connector 70 is provided by the image forming machine 10.

[0084] The following explanation will use an example where the second connecting member is a connector 114. The connector 114 is provided by the first paper feed device 100.

[0085] The first paper feeder 100 may have electrical components such as a motor and sensors, but may not have a control device or power supply used to operate these electrical components. In this case, the electrical components of the first paper feeder 100 are operated by a control device and power supply located in the image forming unit 10. In such cases, the image forming unit 10 and the first paper feeder 100 are electrically connected by a drawer connector 70 and a connector 114.

[0086] In such cases, it is desirable that the first paper feeder 100 be equipped with a button 116 for connecting the drawer connector 70 and the connector 114. Specifically, the drawer connector 70 and the connector 114 are connected by the following operation.

[0087] Figure 13 is a diagram (part 1) showing an example of the operation of connecting the first connecting member and the second connecting member. Similar to Figure 12, Figure 13 shows the state before connecting the drawer connector 70 and the connector 114.

[0088] Furthermore, it is desirable that the drawer connector 70 be configured to be able to be stored in the storage opening 72 by means of the storage opening 72 and the spring 73. When the drawer connector 70 and the connector 114 are connected, it is desirable that the drawer connector 70 be in a position to come out of the storage opening 72 by gravity and the spring 73, as shown in Figure 13.

[0089] The first paper feeder 100 is equipped with a button 116. Specifically, the button 116 has a shape in which a portion of it protrudes outside the first paper feeder 100. When the user presses the button 116, the connector 114 moves in the Y-axis direction. If a drawer connector 70 is present while the button 116 is being pressed, the drawer connector 70 and the connector 114 connect.

[0090] Next, when the image forming unit 10 is placed on the first paper feed device 100, the drawer connector 70 will be in the following state.

[0091] Figure 14 is a diagram (part 2) showing an example of the operation of connecting the first connecting member and the second connecting member. Compared to Figure 13, Figure 14 differs in that the image forming unit 10 is placed on top of the first paper feed device 100. Also, compared to Figure 13, Figure 14 differs in that the drawer connector 70 is stored in the storage opening 72.

[0092] When the image forming machine 10 is placed on the first paper feed device 100, the weight of the image forming machine 10 causes the drawer connector 70 to be retracted into the storage opening 72. In this state, even with the drawer connector 70 in place, there is little interference between the contact surface 300 and the drawer connector 70. Therefore, the user can easily move the image forming machine 10 to align it. Also, because the drawer connector 70 does not interfere easily, the image forming machine 10 can be temporarily placed, thus reducing the time the user has to hold the heavy image forming machine 10.

[0093] Next, if the alignment along the Y-axis is sufficient, the following state will be achieved.

[0094] Figure 15 is a diagram (part 3) showing an example of the operation of connecting the first connecting member and the second connecting member. Compared to Figure 14, Figure 15 differs in that the alignment in the Y-axis direction is sufficient.

[0095] When the alignment in the Y-axis direction is sufficient, the opening 113 is formed in a position that coincides with the drawer connector 70 in the Y-axis direction. Therefore, as shown in Figure 15, when the alignment in the Y-axis direction is sufficient, the drawer connector 70 falls in the Z-axis direction due to gravity and the spring 73, and is stored in the first paper feed device 100 through the opening 113.

[0096] Next, when the user presses button 116, the following state will occur.

[0097] Figure 16 is a diagram (part 4) showing an example of the operation of connecting the first connecting member and the second connecting member. Compared to Figure 15, Figure 16 differs in that the drawer connector 70 and connector 114 are connected by the user pressing button 116.

[0098] When the alignment in the Y-axis direction is sufficient, the drawer connector 70 will be at the same height as the connector 114 in the Z-axis direction. Therefore, when the user presses the button 116, the connector 114 moves and connects with the drawer connector 70. In this way, when the drawer connector 70 and the connector 114 are connected, the image forming unit 10 and the first paper feed device 100 are electrically connected.

[0099] When the image forming unit 10 and the first paper feed device 100 are electrically connected, power and signals can be exchanged between them. This allows the electrical components of the first paper feed device 100 to be operated. Therefore, the first paper feed device 100 can operate its electrical components to transport sheets, etc.

[0100] Furthermore, the first and second connecting members are not limited to the configurations described above. For example, the spring 73 may be omitted.

[0101] Note that the first and second connecting members do not have to be drawer connectors 70 and connectors 114. For example, the first and second connecting members may be harnesses or mechanical components.

[0102] [Fourth Embodiment] Figure 17 shows an example of the overall configuration of the sheet processing apparatus according to the fourth embodiment. Compared to the first embodiment, it differs in that it has a second restricting member such as the second directional member 118. The following explanation will use the example where the second restricting member is the second directional member 118.

[0103] The second directional member 118 is a member that extends in the second direction (in the figure, the X-axis direction. However, since the second direction is perpendicular to the first direction, it differs depending on the direction in which the first direction is set. Hereafter, the second direction will be referred to as the X-axis direction). The second directional member 118 may be integrated with the abutment member 112, or it may be a separate member from the abutment member 112. Furthermore, in the illustrated example, the second directional member 118 is installed at both ends of the first paper feed device 100, but it may be installed at either end.

[0104] The second directional member 118 is made of metal or resin. The second directional member 118 may be integrated with the first paper feed device 100, or it may be a separate component from the first paper feed device 100.

[0105] The second directional member 118 is preferably located at the end of the contact surface 300. In the example shown in Figure 17, the second directional member 118 is at the very end of the X-axis. When the second directional member 118 is located at the end of the contact surface 300 in this way, the user can easily see the second directional member 118. Therefore, when the second directional member 118 is located at the end of the contact surface 300, the user can easily see when to abutting the image forming machine 10 against the second directional member 118 during assembly, making the work easier.

[0106] However, the second directional member 118 may be located at a position other than the end, as long as it is on the contact surface 300. Also, the second directional member 118 may have a shape other than that shown in Figure 17. For example, the second directional member 118 may have a shape in which a part is missing in the Y-axis direction.

[0107] The second directional member 118 restricts the movement of the image forming unit 10 in the second direction. Specifically, the second directional member 118 is used in assembly as follows.

[0108] Figure 18 is a diagram showing an example of assembly of the fourth embodiment in the XY plane. Figure 18 is a diagram showing the process of placing the image forming machine 10 on the contact surface 300 in the XY plane.

[0109] During assembly, the image forming unit 10 is positioned so that it abuts against the abutment member 112 in the depth direction 503 and fits between the second directional members 118 at both ends. In configurations where the second directional member 118 is present on only one side, the image forming unit 10 is positioned during assembly so that it abuts against both the abutment member 112 and the second directional member 118.

[0110] The user can align the parts in the Y-axis direction using the abutment member 112. Furthermore, the user can align the parts in the X-axis direction using the second directional member 118. Thus, with the abutment member 112 and the second directional member 118, the user can easily align the parts in the first and second directions.

[0111] [Fifth Embodiment] The fifth embodiment differs from the first embodiment in that the image forming apparatus 1 further includes the following restricting member and release member.

[0112] Figure 19 shows an example of the overall configuration of the sheet processing device according to the fifth embodiment. Compared to the first embodiment, the fifth embodiment differs in that it has a first button 119A and a second button 120A. Furthermore, compared to the first embodiment, the fifth embodiment differs in that it has a first stopper 119 and a second stopper 120.

[0113] The following explanation will describe an example in which the release members are the first button 119A and the second button 120A, and the limiting members are the first stopper 119 and the second stopper 120. Furthermore, the following explanation will describe an example in which there are two limiting members and two release members, but the number of limiting members and release members is not limited.

[0114] The first button 119A and the second button 120A are designed so that when pressed in the Z-axis direction or released, a portion of the button extends or retracts from the contact surface 300.

[0115] Furthermore, it is desirable that the first button 119A and the second button 120A have rounded tips, that is, the parts that are pressed by the image forming machine 10. With such rounded shapes, the first button 119A and the second button 120A can easily receive the force when force is applied, and they can be easily operated from the bottom surface of the image forming machine 10.

[0116] The first stopper 119 and the second stopper 120 are mechanisms that restrict or release the rotation of the first rotating plate 108 and the second rotating plate 110 when the first button 119A and the second button 120A are pressed or released.

[0117] The first button 119A, the second button 120A, the first stopper 119, and the second stopper 120 have the following mechanisms.

[0118] Figure 20 shows examples of the restricting member and the release member in the fifth embodiment. The following description will focus on the combination of the first button 119A and the first stopper 119. Figure 20 is a transparent view showing examples of the structure and shape of the first button 119A and the first stopper 119.

[0119] Furthermore, the second button 120A and the second stopper 120 have a shape and arrangement that is symmetrical to the first button 119A and the first stopper 119, for example, with respect to the Y-axis.

[0120] The first stopper 119 is housed inside the first paper feed device 100, with a portion of it protruding.

[0121] The first stopper 119 has a spring 121 installed below it. As a result, the elastic force of the spring 121 causes the first button 119A to move away from the contact surface 300. Specifically, the first button 119A and the first stopper 119 operate as follows.

[0122] Figure 21 shows an example of the operation of the limiting member and the release member in the fifth embodiment. Figure 21(A) shows the state before pressing the first stopper 119. On the other hand, Figure 21(B) shows the state when the first stopper 119 is being pressed.

[0123] When the image forming machine 10 is placed on the first stopper 119, the first button 119A and the first stopper 119 change from the state shown in Figure 21(A) to the state shown in Figure 21(B).

[0124] Hereinafter, as shown in Figure 21(B), the position in which the image forming unit 10 can press the first button 119A is referred to as the "predetermined position." Specifically, the predetermined position is the position in the XY plane where a part of the image forming unit 10 is mounted on the first button 119A. Therefore, when the image forming unit 10 is mounted in the predetermined position, the first stopper 119 changes from the state shown in Figure 21(A) to the state shown in Figure 21(B).

[0125] The first stopper 119 has a branched shape from the support column 119B. Specifically, the support column 119B branches out from the contact surface 300 into a part that becomes the first button 119A and a branch portion 119C that extends in the X-axis direction.

[0126] A first clamping mechanism 119D and a second clamping mechanism 119E are formed on the branch portion 119C. In the state shown in Figure 21(A), the first clamping mechanism 119D and the second clamping mechanism 119E clamp the first rotating plate 108, restricting its rotation.

[0127] On the other hand, as shown in Figure 21(B), when the image forming machine 10 is placed, the first button 119A lowers. Then, the first clamping mechanism 119D and the second clamping mechanism 119E move downward in the Z-axis direction. As a result, the first rotating plate 108 becomes capable of rotation, and the restriction is released.

[0128] Furthermore, the restricting member and the release member are not limited to the shapes and configurations described above. In other words, the restricting member and the release member can be configured to restrict or release the rotation of the first rotating plate 108 based on whether the alignment is sufficient or insufficient.

[0129] For example, the branch section 119C, the first clamping mechanism 119D, and the second clamping mechanism 119E may be detachable. Once assembly is complete, the branch section 119C, the first clamping mechanism 119D, and the second clamping mechanism 119E can be removed, and the open section can be closed with a lid. Such a configuration eliminates protrusions and prevents the interior from being visible.

[0130] Figure 22 is a diagram showing examples of the restricting member and the release member in the fifth embodiment in the XY plane. Figure 22 shows the state before the image forming machine 10 is placed. Therefore, since neither the first button 119A nor the second button 120A is pressed, it is in the state shown in Figure 21(A).

[0131] Therefore, both the first rotating plate 108 and the second rotating plate 110 are restricted from rotating by the first stopper 119 and the second stopper 120.

[0132] Next, during assembly, for example, the user performs the following tasks:

[0133] Figure 23 is a diagram (part 1) showing an example of assembly in the fifth embodiment in the XY plane. Compared to Figure 22, Figure 23 differs in that the image forming machine 10 is temporarily placed.

[0134] However, the image forming unit 10 is not in its predetermined position. Therefore, the rotation of both the first rotating plate 108 and the second rotating plate 110 is restricted by the first stopper 119 and the second stopper 120.

[0135] The user can recognize that the image forming machine 10 is not properly aligned because the rotation of both the first rotating plate 108 and the second rotating plate 110 is restricted. Therefore, the user performs the following actions.

[0136] Figure 24 is a diagram (part 2) showing an example of assembly in the fifth embodiment in the XY plane. Compared to Figure 23, Figure 24 differs in that the first button 119A is pressed and the second button 120A is not pressed.

[0137] Because the first button 119A is pressed, the first stopper 119 is in the state shown in Figure 21(B). As a result, the restriction imposed by the first stopper 119 on the first rotating plate 108 is released, and it rotates.

[0138] Since the second button 120A is not pressed, the second stopper 120 is in the state shown in Figure 21(A). Therefore, the second rotating plate 110 is restricted from rotating by the second stopper 120 and cannot rotate.

[0139] The user can recognize that the alignment in the Y-axis direction is sufficient because the restriction imposed by the first stopper 119 is released and the first rotating plate 108 rotates.

[0140] On the other hand, the user can recognize that the image forming machine 10 is not properly aligned in the X-axis direction because the rotation of the second rotating plate 110 is restricted. Therefore, the user performs the following actions.

[0141] Figure 25 is a diagram (part 3) showing an example of assembly in the fifth embodiment in the XY plane. Compared to Figure 24, Figure 25 differs in that both the first button 119A and the second button 120A are pressed.

[0142] Since both the first button 119A and the second button 120A are pressed, both the first stopper 119 and the second stopper 120 are in the state shown in Figure 21(B). Therefore, the restrictions imposed by the first stopper 119 and the second stopper 120 on both the first rotating plate 108 and the second rotating plate 110 are released, and both rotate.

[0143] The user can recognize that, since both the first stopper 119 and the second stopper 120 are released and the first rotating plate 108 and the second rotating plate 110 rotate, the alignment is sufficient in both the X-axis and Y-axis directions. In this way, the user can easily recognize whether the alignment is sufficient based on whether the first rotating plate 108 and the second rotating plate 110 are restricted or not, and assembly can be facilitated.

[0144] [Sixth Embodiment] The devices to be assembled are not limited to a combination of an image forming unit and a sheet supply device, such as the image forming unit 10 and the first paper feeder 100. For example, the devices to be assembled may also be a combination of a first sheet supply device and a second sheet supply device, such as the first paper feeder 100 and the second paper feeder 200.

[0145] Figure 26 shows an example of the overall configuration of the sheet processing device according to the sixth embodiment. Compared with the first embodiment, the sixth embodiment differs in that the devices to be assembled are the first paper feed device 100 and the second paper feed device 200.

[0146] The sixth embodiment involves assembling the first paper feeder 100 and the second paper feeder 200, which are components of the image forming apparatus 1.

[0147] Specifically, if the second paper feed device 200 has a stopper member 112, the user can easily assemble it, similar to the first embodiment.

[0148] [First variation] Figure 27 shows a first modified example of the sheet processing device. Compared to the first embodiment, the first modified example differs in that the axis of rotation of the contact plate is centered in the first direction.

[0149] Specifically, the first rotating plate 108 rotates around the first directional axis 109A. Even with this type of rotation, as in the first embodiment, when the first rotating plate 108 is closed with sufficient alignment of the image forming machine 10 in the X-axis direction, the first rotating plate 108 rotates and comes into contact with the side surface of the image forming machine 10. The same applies to the second rotating plate 110.

[0150] Furthermore, as shown in Figure 9, in a configuration with fitting plates and fitting grooves, when the image forming unit 10 is properly aligned, the first fitting plate 108A, the second fitting plate 108B, the third fitting plate 110A, and the fourth fitting plate 110B align with the fitting grooves and engage.

[0151] As described above, when the image forming machine 10 is sufficiently aligned in the X-axis and Y-axis directions, the first rotating plate 108 and the second rotating plate 110 close, allowing the user to recognize that the alignment is sufficient.

[0152] Furthermore, the first modified example can also be applied to embodiments other than the first embodiment.

[0153] [Second variation] Figure 28 is a diagram (part 1) showing an example of assembly in the second modified example. The second modified example differs from the first embodiment in that the contact surface 300, etc., is not flat.

[0154] For example, the contact surface 300 may have irregularities, such as a convex surface (hereinafter referred to as the "first upper surface 301") and a surface lower than the first upper surface 301 (hereinafter referred to as the "second upper surface 302"). Thus, the shape of the contact surface between the first housing and the second housing is not limited.

[0155] The first upper surface 301 and the second upper surface 302 are surfaces on which the image forming machine 10 can be temporarily placed.

[0156] If the alignment is sufficient, the following state will be achieved.

[0157] Figure 29 is a diagram (part 2) showing an example of assembly in the second modified form. Compared with Figure 28, Figure 29 differs in that the image forming unit 10 is abutting against the abutment member 112. Also, a space 303 may be created by the shapes of the first upper surface 301 and the second upper surface 302.

[0158] Even with shapes such as the first upper surface 301 and the second upper surface 302, the user can easily align the parts in the first direction using the abutment member 112, similar to the first embodiment. Furthermore, with the contact plate, the user can easily align the parts in the X-axis direction. Therefore, by providing the first regulating member and the contact plate, the user can easily assemble the first and second housings.

[0159] [Other embodiments] The sheet processing device may include components other than those described above, or may have a shape other than those described above.

[0160] The sheet processing apparatus is not limited to the image forming apparatus 1. In other words, the sheet processing apparatus can be any apparatus that performs some predetermined processing on a sheet. Furthermore, the sheet may be of a type other than paper.

[0161] The embodiments described above are preferred examples, but those skilled in the art can realize various modifications from the disclosed information. Such modifications are also included within the technical scope described in the claims. [Explanation of symbols]
