Description

  The present invention relates to an image processing apparatus including an operation unit on an upper surface of an apparatus main body.

  In image processing apparatuses such as an image forming apparatus and an image reading apparatus, an operation unit for controlling image processing in the apparatus main body is often arranged on the upper surface of the apparatus main body in order to improve operability. In recent years, there has been a high demand for an increase in the number of input keys accompanying an increase in the number of functions of an image processing apparatus and an increase in the size of an input key for improving operability, and there is a need to increase the size of an operation unit. As a means for increasing the size of the operation unit, a configuration in which the operation unit is freely displaceable between a storage position and a drawer position is conceivable (for example, see Patent Document 1). For example, the first operation unit including the display unit is disposed on the upper surface of the apparatus main body, and the second operation unit that accepts an input operation is freely displaceable between a storage position and a pull-out position. The area of the entire operation part including the part increases.

JP 2002-171372 A

  By the way, when a user on a wheelchair operates the image processing apparatus, the operation unit is arranged on the upper surface of the apparatus main body, so that the user has difficulty in visually recognizing the operation unit and the operability is not good. In order to solve this problem, it can be considered that the first operation unit is configured to be rotatable so as to be inclined downward toward the front side of the apparatus main body. In addition, the second operation unit is configured so as to be held by the first operation unit and to be displaceable with respect to the first operation unit, rather than being configured to be displaceable with respect to the apparatus main body. Manufacturing as a unit is easier.

  However, when the second operation unit is held by the first operation unit, when the first operation unit is tilted, the second operation unit is also tilted. For a user in a wheelchair, the operability is better when the first operation unit including the display unit is inclined, whereas the operability is lowered when the second operation unit that receives an input operation is inclined.

  An object of the present invention is to provide an image processing apparatus that is easy to operate for a user in a wheelchair.

  The image processing apparatus according to the present invention includes an apparatus main body, a first operation unit, a second operation unit, and an angle holding member. The apparatus main body performs image processing. The first operation unit has at least a display unit for displaying processing contents of the apparatus main body, is disposed on the upper surface of the apparatus main body, and connects one side surface of the apparatus main body to the other side surface which is the back surface of the one side surface. It is comprised so that it can rotate with respect to the apparatus main body centering on the rotating shaft arrange | positioned in this. The second operation unit receives an input operation for controlling the apparatus main body. The second operation unit is held by the first operation unit so as to be freely displaceable between a storage position disposed so as to overlap the first operation unit and a drawing position where the second operation unit is pulled out from the first operation unit to the front side of the apparatus main body. Is done. The angle holding member holds the angle of the second operation unit constant regardless of the rotation state of the first operation unit with respect to the apparatus main body.

  In this configuration, the first operation unit rotates in a direction connecting the front side and the back side of the apparatus main body around a rotation shaft arranged in a direction connecting the one side surface and the other side surface of the apparatus main body. The first operation unit is disposed on the upper surface of the apparatus main body, but the visibility of the display unit from a low position is improved by rotating the first operation unit so as to be inclined downward toward the front side. When only the first operation unit is used and the second operation unit is not used, the second operation unit is disposed at the storage position. When using the second operation unit, the second operation unit is pulled out to the pull-out position. The second operation unit is held by the first operation unit, but the angle is held constant regardless of the rotation state of the first operation unit with respect to the apparatus main body. For this reason, the 2nd operation part is arranged in a drawer position, maintaining the same angle as before rotating the 1st operation part. Since the first operation section before rotation is arranged in a substantially horizontal direction along the upper surface of the apparatus main body, the second operation section is held in a substantially horizontal direction regardless of the rotation state of the first operation section with respect to the apparatus main body. .

  In the above-described configuration, the first operation unit is pivotally supported by the apparatus main body at the first back side end, which is the end on the back side opposite to the front side, and the second operation unit is on the front side of the apparatus main body. The holding body pivotally supported by the first front side end portion of the first operation portion disposed on the second front side end portion of the second operation portion, and freely displaceable between the storage position and the drawer position with respect to the holding body And a second operation unit main body.

  Since the first operation unit is pivotally supported at the first rear side end by the apparatus main body, the first front side end rotates in the vertical direction. By rotating the first operation unit so as to be inclined downward toward the front side, the first operation unit becomes lower than before the rotation. In addition, since the first front side end of the first operation unit is lower than before rotation and the second operation unit is pivotally supported by the first front side end, the second operation unit is also lower than before rotation.

  The angle holding member is a cam pivotally supported on the first back side end so as to rotate with the rotation of the first operation unit, and the first back side end with the rotation of the first operation unit. And a cam that adjusts the distance between the second back side end of the holding body and an elastic member that urges the second back side end in the direction of approaching the first back side end. be able to.

  The second back side end of the second operation unit is attracted to the first back side end of the first operation unit by the elastic member. On the other hand, the distance between the first back side end and the second back side end is determined by the cam so that the second operation unit is held in a substantially horizontal direction regardless of the rotation state of the first operation unit with respect to the apparatus body. It is prescribed. Since the structure is simple as described above, the image processing apparatus can be downsized and the manufacturing cost can be reduced.

  Furthermore, a first gear disposed concentrically with the rotating shaft and fixed to the apparatus main body, and a second gear that meshes with the first gear and rotates integrally with the cam are further provided. Can be configured. By rotating the first operation portion so as to incline downward toward the front side, the second gear rotates while moving downward, and the cam also rotates together with the second gear. Thereby, the space | interval of a 1st back surface side edge part and a 2nd back surface side edge part is expanded. For this reason, the second operation unit is held in a substantially horizontal direction regardless of the rotation state of the first operation unit with respect to the apparatus main body.

  The apparatus body includes an image reading unit that performs an image reading process of reading an image of a document and generating image data, and an image forming unit that is disposed below the image reading unit and performs an image forming process on a recording medium. The image forming unit can be configured to include a space for providing a paper discharge tray for storing a recording medium subjected to image formation processing between the image reading unit and the image reading unit.

  The apparatus main body includes an image reading unit disposed at an upper portion and an image forming unit disposed below the image reading unit, and has a so-called in-body discharge shape. The paper discharge tray is disposed in a space below the image reading unit, and the first operation unit and the second operation unit are disposed on the upper surface of the image reading unit. The second operation unit is pulled out while maintaining a substantially horizontal state on the front side of the main body of the apparatus when in use, and is stored so as to overlap under the first operation unit when not in use. Does not hinder the removal of the recording medium. Therefore, the workability of taking out the recording medium from the paper discharge tray is good.

  According to the present invention, it is possible to improve the operability for a user who is in a wheelchair.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1 and 2, the image processing apparatus 10 includes an apparatus main body 100, an automatic document feeder (ADF) 200, a control unit 300, a first operation unit 400, and a second operation unit 500. I have.

  The apparatus main body 100 includes an image reading unit 110, an image forming unit 120, and a paper feeding unit 130. The image reading unit 110 is disposed at the top of the apparatus main body 100, the image forming unit 120 is disposed below the image reading unit 110, and the paper feeding unit 130 is disposed below the image forming unit 120.

  The image forming unit 120 includes a space 83 for providing a paper discharge tray 67 that accommodates the paper on which image formation has been performed, and the image reading unit 110 has a partial horizontal cross-sectional area that reads the image. It is formed smaller than the portion 110. Thus, the apparatus main body 100 has a so-called in-cylinder discharge shape. Examples of the paper include recording media such as photographic paper and OHP film.

  The image reading unit 110 includes a first document table 21, a second document table 22, a light source unit 23, a mirror unit 24, a lens 25, and a solid-state imaging device (CCD: Charge Coupled Device) 26, and reads an image of a document. An image reading process for generating image data is performed. The image reading process is included in the image processing.

  In the ADF 200, a document transport path 93 is formed from the document stacking tray 91 to the document discharge tray 92 via the second document table 22. The ADF 200 conveys documents one by one to the document conveyance path 93. The ADF 200 is rotatable about the end portion on the back side R, which is the opposite side of the front side F, so as to cover the top surface of the first document table 21 so that it can be opened and closed. By rotating the ADF 200 so that the end portion of the front side F moves upward to expose the upper surface of the first document table 21, the document is placed on the first document table 21 by manual operation without using the ADF 200. can do.

  Both the first document table 21 and the second document table 22 are made of hard glass plates.

  The light source unit 23 and the mirror unit 24 are movable in the sub-scanning direction along the first document table 21 and the second document table 22 below the first document table 21 and the second document table 22. The moving speed of the mirror unit 24 is set to ½ of the moving speed of the light source unit 23. The light source unit 23 includes a light source and a first mirror. The mirror unit 24 includes a second mirror and a third mirror.

  When reading an image of a document conveyed by the ADF 200, the light source unit 23 is stopped below the second document table 22. The light from the light source is emitted toward the image surface of the document passing over the second document table 22, and the reflected light on the image surface of the document is reflected toward the mirror unit 24 by the first mirror.

  When reading an image of a document placed on the first document table 21, the light source unit 23 and the mirror unit 24 move below the first document table 21 in the sub-scanning direction. The light from the light source is emitted toward the image surface of the document placed on the first document table 21, and the reflected light on the image surface of the document is reflected toward the mirror unit 24 by the first mirror.

  Regardless of whether or not the ADF 200 is used, the reflected light on the image surface of the document is incident on the CCD 26 via the lens 25 by the second mirror and the third mirror with a constant optical path length.

  The CCD 26 outputs an electrical signal corresponding to the amount of reflected light on the image surface of the document. This electrical signal is input to the control unit 300 as image data. In this way, the image reading unit 110 reads an image of a document and generates image data. The control unit 300 outputs image data to the image forming unit 120 as necessary.

  The image forming unit 120 includes an exposure unit 3, four image forming units 51, 52, 53, 54, an intermediate transfer belt unit 6, a secondary transfer roller 66, a fixing device 7, a paper discharge tray 67, and a paper transport path. 68 and 69, and performs image forming processing on the paper. The image forming process is included in the image processing.

  The intermediate transfer belt unit 6 includes an intermediate transfer belt 61, a driving roller 62, a driven roller 63, and a tension roller. The intermediate transfer belt 61 is stretched between the driving roller 62 and the driven roller 63 to form a loop-shaped moving path.

  The image forming unit 120 uses black and image data corresponding to four hues of cyan, magenta, and yellow, which are three subtractive primary colors obtained by color separation of a color image. , 52, 53, and 54, image forming processing is performed. The image forming units 51 to 54 are arranged in a line along the movement path of the intermediate transfer belt 61. The image forming units 52 to 54 are configured in substantially the same manner as the image forming unit 51.

  The black image forming unit 51 includes a photosensitive drum 1, a charging device 2, a developing device 4, a primary transfer roller 5, and a cleaning unit 64.

  The charging device 2 uniformly charges the surface of the photosensitive drum 1 to a predetermined potential.

  The exposure unit 3 includes a semiconductor laser, a polygon mirror, a first fθ lens, and a second fθ lens (not shown). Each of the laser beams modulated by image data of black, cyan, magenta, and yellow hues is image-formed. Irradiate each of the photosensitive drums 1 of the sections 51 to 54. On each peripheral surface of the four photosensitive drums 1, electrostatic latent images based on image data of each hue of black, cyan, magenta, and yellow are formed.

  The developing device 4 supplies the toner (developer) of each hue of the image forming units 51 to 54 to the peripheral surface of the photosensitive drum 1 on which the electrostatic latent image is formed, and converts the electrostatic latent image into the developer image. To visualize.

  The cleaning unit 64 collects toner remaining on the surface of the photosensitive drum 1 after development and image transfer.

  The outer peripheral surface of the intermediate transfer belt 61 faces the four photosensitive drums 1 in order. A primary transfer roller 5 is disposed at each position facing the respective photosensitive drums 1 with the intermediate transfer belt 61 interposed therebetween. Each of the positions where the intermediate transfer belt 61 and the photosensitive drum 1 face each other is a primary transfer position.

  A primary transfer roller 5 is provided with a primary transfer bias for charging the toner with a negative polarity and a reverse polarity (plus) in order to transfer the developer image carried on the peripheral surface of the photosensitive drum 1 onto the intermediate transfer belt 61. Is applied by constant voltage control. As a result, the developer images of the respective colors formed on the respective photosensitive drums 1 are sequentially transferred (primary transfer) to the outer peripheral surface of the intermediate transfer belt 61 and transferred onto the outer peripheral surface of the intermediate transfer belt 61. An image is formed.

  However, when image data of only a part of the hues of yellow, magenta, cyan, and black is input, only a part of the four photosensitive drums 1 corresponding to the hue of the input image data is static. An electrostatic latent image and a developer image are formed. For example, in the monochrome printing mode, the electrostatic latent image and the developer image are formed only on the photosensitive drum 1 of the image forming unit 51 corresponding to the black hue, and the intermediate transfer belt 61 has black on the outer peripheral surface. Only the developer image is transferred (primary transfer).

  At the time of full color image formation in which image formation processing is performed in all of the image forming units 51 to 54, the four primary transfer rollers 5 press the intermediate transfer belt 61 against all the photosensitive drums 1. On the other hand, during monochrome image formation in which image formation processing is performed only in the image forming section 31, the primary transfer roller 5 presses the intermediate transfer belt 61 against the photosensitive drum 1 only in the image forming section 51.

  Each primary transfer roller 5 is configured by covering the surface of a shaft made of a metal (for example, stainless steel) having a diameter of 8 to 10 mm with a conductive elastic material, and the intermediate transfer belt 61 is formed with the conductive elastic material. A high voltage is applied uniformly to.

  The secondary transfer roller 66 is in pressure contact with the drive roller 62 with a predetermined nip pressure across the intermediate transfer belt 61. The secondary transfer roller 6 is a conductive resin and is made of a hard material. The secondary transfer roller 66 transfers (secondary transfer) the developer image carried on the outer peripheral surface of the intermediate transfer belt 61 to a sheet.

  The developer image transferred to the outer peripheral surface of the intermediate transfer belt 61 at each of the primary transfer positions is a secondary transfer position that is a position where the intermediate transfer belt 61 and the secondary transfer roller 66 are opposed by the rotation of the intermediate transfer belt 61. It is conveyed to.

  Paper is stored in the paper supply tray 81 of the paper supply unit 130. In the paper transport path 68, a plurality of transport rollers 12A and 12B are arranged. The paper transport path 68 is arranged in a substantially vertical direction in order to send the paper stored in the paper feed tray 81 to the paper discharge tray 67 via the secondary transfer position and the fixing device 7.

  A plurality of transport rollers 12 </ b> C and 12 </ b> D are arranged in the paper transport path 69. The sheet conveyance path 69 is provided from the downstream side of the fixing device 7 to the upstream side of the secondary transfer position in the sheet conveyance direction. The paper discharged to the paper discharge tray 67 after passing through the fixing device 7 is transferred to the paper transfer path 69 with the rear end up to that point in front. As a result, the sheet is retransmitted to the secondary transfer position with the front and back sides reversed.

  The paper feed unit 130 includes a manual feed tray 82 in addition to the paper feed cassette 81. Paper is stored in each of the paper feed cassette 81 and the manual feed tray 82.

  The paper feed unit 130 feeds paper one by one from either the paper feed cassette 81 or the manual feed tray 82. The paper stored in the paper feed cassette 81 is fed by the pickup roller 11A and conveyed to the secondary transfer position via the paper conveyance path 68. The paper accommodated in the manual feed tray 82 is fed by the pickup roller 11B and conveyed to the secondary transfer position via the paper conveyance path 68.

  A registration roller 13 is disposed on the upstream side of the secondary transfer position in the sheet conveyance direction. The registration roller 13 starts to rotate at the timing when the leading edge of the sheet fed from the sheet feeding cassette 81 or the manual feed tray 82 is aligned with the leading edge of the developer image formed on the surface of the intermediate transfer belt 61, and the secondary transfer. Feed paper to the position.

  When the sheet fed from the sheet feeding unit 130 passes through the secondary transfer position, a high transfer voltage having the same polarity (minus) as the toner charging polarity (minus) is applied to the driving roller 62. As a result, the developer image is secondarily transferred from the outer peripheral surface of the intermediate transfer belt 61 to the surface of the sheet.

  The developer remaining on the intermediate transfer belt 61 after the developer image is transferred to the sheet is collected by the intermediate transfer belt cleaning device 65.

  The sheet on which the developer image is transferred is guided to the fixing device 7 and is heated and pressed by passing between the heating roller 71 and the pressure roller 72. As a result, the developer image is firmly fixed on the surface of the paper. The paper on which the developer image is fixed is discharged onto the paper discharge tray 67 with the surface on which the developer image is fixed facing down.

  The control unit 300 controls the image processing apparatus 10 in an integrated manner.

  The first operation unit 400 is arranged on the upper surface F of the apparatus main body 100 and on the front side F from the ADF 200.

  As shown in FIG. 3, in this embodiment, of the operation panel 101 on the upper surface of the apparatus main body 100, a first display unit 410 including a display unit 410 that displays processing contents and operation states of the apparatus main body 100 and a plurality of operation keys 420 is included. The operation unit 400 is configured to be displaceable separately from the part including the other operation keys 102. For example, a liquid crystal touch panel is used as the display unit 410.

  In FIG. 4 (A) and FIG. 4 (B), illustration of the apparatus main body 100 is omitted. As shown in FIGS. 4A and 4B, the first operation unit 400 has a first back side end 401, which is an end on the back side R, pivotally supported by the frame 103 of the apparatus main body 100. Yes. The first operation unit 400 is a device main body centering on a rotation shaft 32 arranged in the left-right direction connecting one side surface 104 (see FIG. 2) of the device main body 100 and the other side surface 105 serving as the back surface of the side surface 104. 100 is configured to be rotatable with respect to 100. In addition, although the rotating shaft 32 is arrange | positioned at each of the left-right edge part in this embodiment, it can also be comprised with one rotating shaft extended in the left-right direction.

  As shown in FIG. 4A, the first operation unit 400 is inclined down to the normal position along the upper surface of the apparatus main body 100 and to the front side F of the apparatus main body 100 as shown in FIG. 4B. It is possible to rotate between the inclined position rotated in this way. The second operation unit 500 is held by the first operation unit 400. Details of the configuration in which the first operation unit 400 rotates will be described later.

  The second operation unit 500 receives an input operation for controlling the apparatus main body 100. As shown in FIGS. 4 (A) and 4 (B), the second operation unit 500 has a storage position arranged so as to overlap the first operation unit 400, and FIGS. 5 (A) and 5 (B). ), The first operation unit 400 holds the first operation unit 400 so as to be freely displaceable between the first operation unit 400 and the drawing position drawn to the front side F of the apparatus main body 100.

  The first operation unit 400 is rotatable between the normal position and the inclined position regardless of whether the second operation unit 500 is located in the storage position or the drawer position.

  As shown in FIGS. 6 and 7, the second operation unit 500 includes a holding body 510, a keyboard case 520, and a keyboard 530. The keyboard 530 is fixed in the keyboard case 520, and the keyboard 530 and the keyboard case 520 are displaced together. The keyboard 530 and the keyboard case 520 constitute a second operation unit main body.

  Slide rails 511 and 512 are provided on the holder 510 and the keyboard case 520, respectively. The keyboard case 520 is displaced to the storage position and the drawer position with respect to the holding body 510 when the slide rails 511 and 512 slide. The displacement between the storage position and the drawer position of the keyboard case 520 is performed manually.

  8A, FIG. 8B, FIG. 9A, and FIG. 9B, the holding body 510 is the first front side end portion of the first operation unit 400 disposed on the front side F. The second front side end portion 502 disposed on the front side F is pivotally supported by 402.

  One end of the coil spring 45 is fixed to the second back side end 501 of the holding body 510 arranged on the back side R, and the other end of the coil spring 45 is fixed to the first back side end 401 of the first operation unit 400. Is fixed. The coil spring 45 urges the second back side end portion 501 in the direction in which it approaches the first back side end portion 401. Instead of the coil spring 45, an elastic member such as rubber can be used.

  The first operation unit 400 is pivotally supported on the frame 103 of the apparatus main body 100 by the hinge 30. One end of the hinge 30 is fixed to the frame 103, and the other end 31 is fixed to the pin 41 of the first operation unit 400. The pin 41 is erected on the side surface of the first back side end 401. The first operation unit 400 rotates around the rotation axis 32 of the hinge 30 in a direction connecting the front side F and the back side R of the apparatus main body 100. A tilt hinge is used as the hinge 30. The tilt hinge can smoothly rotate with a constant torque in the operation range and can stop at a desired angle.

  The first operation unit 400 is disposed on the upper surface of the apparatus main body 100. By rotating the first operation unit 400 to the inclined position so as to incline downward toward the front side F, the visibility of the display unit 410 from a lower position than before the rotation is achieved. Get better. Although the user who got on the wheelchair sees the display unit 410 from a low position, the visibility of the display unit 410 is good even from a lower position than before the rotation. Will be better.

  The hinge 30 has a first gear 33 disposed concentrically with the rotating shaft 32. The first gear 33 is fixed to the frame 103 of the apparatus main body 100.

  The pin 41 pivotally supports the second gear 42 and the cam 43. The second gear 42 meshes with the first gear 33. The cam 43 rotates integrally with the second gear 42. An eccentric plate cam is used as the cam 43.

  When the first operation unit 400 rotates from the normal position to the inclined position, the second gear 42 rotates in the same direction as the first operation unit 400 as the first operation unit 400 rotates, and the second gear 42 rotates. Accordingly, the cam 43 also rotates in the same direction as the first operation unit 400.

  A boss 44 protrudes on the side surface of the second back side end portion 501 of the holding body 510 disposed on the back side R. The outer peripheral portion constituting the contour of the cam 43 slides on the peripheral surface of the boss 44.

  As the first operating unit 400 rotates from the normal position to the inclined position, the cam 43 rotates, so that the first back side end 401 of the first operating unit 400 and the second back side end of the holding body 510 are rotated. The distance from 501 is adjusted. Therefore, by adjusting the shape of the outer peripheral portion of the cam 43, the angle of the second operation unit 500 can be kept constant regardless of the rotation state of the first operation unit 400 relative to the apparatus main body 100. The cam 43, the boss 44, and the coil spring 45 are included in the angle holding member.

  The second operation unit 500 is held by the first operation unit 400, but the first operation unit 400 is rotated because the angle is held constant regardless of the rotation state of the first operation unit 400 with respect to the apparatus main body 100. It is arranged at the pull-out position while maintaining the same angle as when in the previous normal position. Since the first operation unit 400 in the normal position is disposed in a substantially horizontal direction along the upper surface of the apparatus main body 100, the second operation unit 500 is substantially the same regardless of the rotation state of the first operation unit 400 with respect to the apparatus main body 100. Holds horizontally.

  Moreover, since the 1st operation part 400 is pivotally supported by the apparatus main body 100 at the 1st back surface side edge part 401, the 1st front surface side edge part 402 rotates to an up-down direction. By rotating the first operation unit 400 from the normal position to the inclined position so as to incline downward to the front side F, the first front side end 402 of the first operation unit 400 becomes lower than before rotation. Since the 2nd operation part 500 is pivotally supported by the 1st front side end 402, if the 1st front side end 402 becomes lower than before rotation, the 2nd operation part 500 will also become lower than before rotation.

  As shown in FIG. 10, when the user on the wheelchair operates the image processing apparatus 10, the first operation unit 400 is inclined downward to the front side F by rotating the first operation unit 400 to the inclined position. Therefore, the visibility of the display unit 410 can be improved.

  When the user who has used the wheelchair uses only the first operation unit 400 and does not use the second operation unit 500, the user places the second operation unit 500 in the storage position, and uses the second operation unit 500 when the second operation unit 500 is used. 2 The operation unit 500 can be pulled out to the pull-out position.

  By arranging the first operation unit 400 in the inclined position, the arrangement of the second operation unit 500 becomes lower than in the case where the first operation unit 400 is in the normal position, and the angle of the second operation unit 500 is set in the horizontal direction. Since it is held, the user on the wheelchair pulls the second operation unit 500 to the pull-out position, so that the operability with respect to the keyboard 530 is improved.

  The apparatus main body 100 has a so-called in-cylinder discharge shape, the paper discharge tray 67 is disposed in a space 83 below the image reading unit 110, and the first operation unit 400 and the second operation unit 500 It is disposed on the upper surface of the reading unit 110. The second operation unit 500 is pulled out while maintaining a horizontal state on the front side F of the apparatus main body 100 when in use, and is stored so as to overlap under the first operation unit 400 when not in use. It does not interfere with the removal of the paper from the paper tray 67. Therefore, the workability of taking out the paper from the paper discharge tray 67 is good.

  Note that a keyboard as shown in FIG. 11 may be displayed on the display unit 410 to enable character input from the first operation unit 400. Thus, an e-mail address or the like can be input without pulling out the second operation unit 500 to the pull-out position.

  Further, the entire operation panel 101 can be configured to be rotatable with respect to the apparatus main body 100 as the first operation unit 400.

  The image processing apparatus 10 can be configured as an image reading apparatus that does not include the image forming unit 120 and the paper feeding unit 130, and can also be configured as an image reading apparatus that does not include the ADF 200. The image processing apparatus 10 can also be configured as an image forming apparatus that does not include the ADF 200 and the image reading unit 110.

  The above description of the embodiment is to be considered in all respects as illustrative and not restrictive. The scope of the present invention is shown not by the above embodiments but by the claims. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
