Description

  The present invention relates to an image of a copying machine, a printer, a facsimile machine, or the like provided with a cover member that exposes the inside of the apparatus main body that has been covered by moving in a direction away from the apparatus main body and a handle for transportation. The present invention relates to a forming apparatus.

  The image forming apparatus conveys the recording medium from a recording medium accommodating unit that accommodates a sheet-like recording medium such as transfer paper to an image forming unit that forms an image on the recording medium, and further discharges the recording medium on which the image is formed. Transport to the paper section. In such an image forming apparatus, the recording medium conveyance path is covered when in use, and the recording medium conveyance path inside the apparatus main body is exposed by moving the moving end in a direction away from the apparatus main body about the cover rotation axis. There are known ones provided with an opening / closing cover to be operated (Patent Documents 1 and 2). In this image forming apparatus, when the recording medium is jammed in the recording medium conveyance path, the recording medium conveyance path is exposed by opening the opening / closing cover, and the recording medium can be removed.

  In the image forming apparatuses described in Patent Document 1 and Patent Document 2, a recording medium storage unit is disposed below the apparatus main body, and an image forming unit is disposed in the center of the apparatus main body above the recording medium storage unit. A paper discharge unit is disposed on the upper part of the apparatus main body above the forming unit. An open / close cover that covers the recording medium conveyance path for conveying the recording medium from the recording medium accommodating portion at the lower part of the apparatus main body to the paper discharge unit at the upper part of the apparatus main body is provided on the side surface of the apparatus main body (hereinafter referred to as “device side surface”) In preparation.

  Since this open / close cover covers the recording medium conveyance path from the lower part to the upper part of the apparatus main body, the vertical dimension of the open / close cover is slightly smaller than the vertical dimension on the side surface of the apparatus. Further, in the image forming apparatus, it is necessary to be able to remove recording media of all sizes used when the opening / closing cover is opened. Therefore, the width of the opening / closing cover (the length in the direction orthogonal to the vertical direction on the side surface of the apparatus) is larger than the width of the recording medium having the widest width (the length in the direction orthogonal to the transport direction) among the recording media to be used. Is also widely set.

2. Description of the Related Art As a handle portion for placing a hand when an image forming apparatus is transported, a handle portion having a recess (concave portion) provided in a part of an exterior of a casing forming a side surface of the apparatus is known.
A configuration in which a recessed handle portion is provided in the device body on both outer sides in the width direction of the opening / closing cover as a configuration in which a handle portion is provided on the side surface of the device on which the opening / closing cover is disposed. Can be considered. However, a handle portion having a recess (about 10 cm) wide enough to allow the index finger to the little finger of a human hand to enter the outer side of the open / close cover wider than the maximum width of the recording medium to be used. If two are provided, the width of the side surface of the apparatus provided with the opening / closing cover will be widened. When the width of the side surface of the apparatus is increased, the projection area when the image forming apparatus is projected from the upper side to the lower side is increased, leading to an expansion of the installation space.
If the width of the handle is narrowed to prevent the side of the device from becoming wider, the handle becomes unstable and difficult to carry. There is a risk of damage.

In the image forming apparatus disclosed in Patent Document 1, a recessed handle portion is provided on one outer side in the width direction of the opening / closing cover on the side surface of the apparatus, and a direction perpendicular to the side surface of the apparatus is provided on the other outer side along the rod-shaped longitudinal direction. A rod-shaped handle that can be taken in and out is provided. In such a configuration, a hand is placed on one of the recessed handle portions, and the other hand, the handle of the rod-shaped handle that is pulled out is held by hand. Can be prevented from falling and the device falling.
In addition, the rod-like handle portion for gripping with a hand needs to have a length that can be sufficiently extended from the index finger to the little finger of a human hand as the length of the rod-like longitudinal direction. However, the rod-shaped diameter only needs to be long enough to support the lower part between the first joint and the second joint of the finger of a human hand (around 2 [cm]). Since the width required to arrange the rod-shaped handle portion having such a diameter is narrower than the depressed handle portion for placing the hand, it is possible to suppress the width of the side surface of the apparatus provided with the opening / closing cover from becoming wide. .
If the rod-like handle portion protrudes from the side surface of the apparatus, it leads to a decrease in the aesthetic quality of the appearance, and there is a possibility that a person passing around the image forming apparatus may hit the handle portion. In the image forming apparatus of Patent Document 1, since the rod-shaped handle portion can be taken in and out of the device side surface, the rod-shaped handle portion can be accommodated in the device side surface except during transportation, and the aesthetic quality of the appearance is deteriorated. It is possible to prevent people from hitting the handle part.

  However, there is a possibility that the rod-like handle portion that can be taken in and out may be retracted unexpectedly during transportation of the device. If the rod-like handle part is retracted during transportation of the device, the hand may come off and the device may fall and be damaged. Moreover, there is a possibility that the rod-like handle portion may protrude from the side surface of the device for some reason, such as forgetting to put the rod-like handle portion after the device is transported. If the rod-like handle portion is still protruding, there is a possibility that the aesthetic quality of the appearance in the installed state is deteriorated or that a person hits the handle portion of the installed device.

  As a configuration in which the handle portion does not protrude from the side surface of the apparatus while suppressing the expansion of the installation space, a configuration in which the handle portion is provided on the opening / closing cover itself can be considered. However, when a handle is provided on the opening / closing cover, the weight of the device body is applied to the member that attaches the opening / closing cover such as the rotation shaft of the opening / closing cover to the device body and the opening / closing cover, and the member that attaches the opening / closing cover. Otherwise, damage such as deformation of the opening / closing cover may occur. In order to prevent such damage, an attempt to increase the strength of the member that attaches the opening / closing cover to the apparatus main body or the opening / closing cover leads to high costs. For this reason, it is desirable that the handle portion is not provided in a portion that moves relative to the apparatus main body like the opening / closing cover, but is fixed to the apparatus main body.

  Such a problem is not limited to a configuration in which the recording medium conveyance path is exposed by opening the opening / closing cover, but a configuration in which the inside of the apparatus main body covered by the cover member is exposed by opening the cover member. Then, the same problem can occur. Further, the cover member is not limited to a configuration that opens and closes by rotating around a rotation axis. As long as at least part of the cover member moves in a direction away from the device main body, such as a configuration that pulls out from the device main body or a configuration that removes the cover member itself from the device main body, it exposes the covered device main body. Similar problems can arise.

  The present invention has been made in view of the above problems, and its purpose is to provide a cover member on the side surface, and suppress the expansion of the installation space, and the handle portion does not protrude from the side surface. It is an object of the present invention to provide an image forming apparatus capable of carrying out the above described transportation.

  In order to achieve the above object, an invention according to claim 1 is provided with an image forming means for forming an image on the surface of a sheet-like recording medium, and disposed on a side surface of the apparatus main body, and at least a part thereof is away from the apparatus main body. In an image forming apparatus having a cover member that exposes the inside of the apparatus main body that has been covered, the image forming apparatus is fixed to the apparatus main body as a handle for conveying the apparatus and is recessed with respect to the side surface of the exterior of the apparatus main body At least one of the ellipse-shaped handle portions is arranged at a position lower than the cover member within the width of the cover member in the width direction of the side surface.

  In the present invention, the handle portion has a recessed shape with respect to the surface of the exterior of the apparatus main body, and therefore the handle portion does not protrude from the side surface of the apparatus. Thereby, the aesthetic quality of the external appearance at the time of use can be prevented, and it can be prevented that a person hits the handle part at the time of use. In addition, since the handle portion is fixed to the apparatus main body, the cover member and the member to which the cover member is attached may be damaged during transportation as compared with the configuration in which the handle portion is provided on the cover member movable with respect to the apparatus main body. And can be transported stably. Furthermore, since at least one of the handle portions having a shape recessed at a position lower than the cover member within the width of the cover member is provided, a handle portion having a width enough to stabilize a human hand is provided. However, it can suppress that the width | variety of the apparatus side surface which provided the cover member becomes wide. Since the width of the side surface of the apparatus can be suppressed while stabilizing the clues, it is possible to perform stable transportation while suppressing the expansion of the installation space.

  According to the present invention, the structure having the cover member on the side surface has an excellent effect that it is possible to carry out stable transportation during device transportation without suppressing the expansion of the installation space and without protruding the handle portion from the side surface. Is obtained.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, a configuration example of the image forming apparatus according to the present embodiment will be described.
FIG. 2 is a schematic configuration diagram showing an example of the overall configuration of a copying machine 500 that is an image forming apparatus according to the present embodiment. A copier 500 shown in FIG. 2 is a color image forming apparatus that forms one image from four-color toners of yellow (hereinafter referred to as Y), magenta (hereinafter referred to as M), cyan (hereinafter referred to as C), and black (hereinafter referred to as K). It is. The copier 500 includes an image forming unit 60, a paper feeding unit 2, a scanner 3 as an image reading unit that reads an image of a document that is an image forming target, and the like. A double-sided cover 31 having a reverse conveying unit is provided on the right side of the image forming unit 60 in the drawing.

  The image forming unit 60 includes four image forming units 5 (Y, M, C, K) that form respective colors, and these are arranged along an intermediate transfer belt 121 whose surface moves in the direction of arrow F in the figure. ing. Each image forming unit 5 (Y, M, C, K) has a photoreceptor 1 (Y, M, C, K) as a drum-shaped image carrier. Further, the image forming unit 60 includes an exposure device 4.

  Inside the intermediate transfer belt 121, a primary transfer roller 24 (Y, M, C, K) for transferring a toner image from the photoreceptor 1 (Y, M, C, K) onto the intermediate transfer belt 121 is provided. . A secondary transfer roller 23 is provided downstream of the primary transfer roller 24 (Y, M, C, K) so as to face the surface of the intermediate transfer belt 121. Further, an intermediate transfer belt cleaning device (not shown) for cleaning the surface of the intermediate transfer belt 121 after transferring the toner image is provided downstream of the secondary transfer roller 23. In the copying machine 500 according to the present embodiment, these are integrally formed, and form an intermediate transfer unit 120 that can be attached to and detached from the copying machine 500 main body. Note that the image forming unit 5 (Y, M, C, K), the exposure device 4, the intermediate transfer unit 120, the fixing device 8 and the like image the transfer paper P as a recording medium based on the image information read by the scanner 3. The image forming means for forming the image is configured.

  The scanner 3 disposed above the image forming unit 60 includes a first traveling body having a light source, a second traveling body having a mirror, an imaging lens, a reading sensor (all not shown), and the like.

  An exposure device 4 is provided below the four image forming units 5 (Y, M, C, K). In addition, the paper feeding unit 2 is provided below the image forming unit 60. The paper feed unit 2 includes a paper feed cassette 2a for storing the transfer paper P and a paper feed roller 27 as a paper feed unit. A fixing device 8 for fixing an image on the transfer paper P and a paper discharge roller 26 are provided above the secondary transfer roller 23.

  Since the four image forming units 5 (Y, M, C, K) have the same configuration except that the colors of the toners to be stored are different, the following description will be made with reference numerals omitted as appropriate. The image forming unit 5 is a charging device (not shown) that applies a charge to the surface of the photosensitive member 1 around the photosensitive member 1, and a developing device (not shown) that develops a latent image formed on the surface of the photosensitive member 1 with each color toner. Equipment. In addition, a cleaning device (not shown) for cleaning the surface of the photoreceptor 1 after the toner image transfer is disposed.

Next, an operation example of the copying machine 500 according to the present embodiment will be described.
When the image start signal is received, the intermediate transfer belt 121 starts to move. At the same time, in the yellow image forming unit 5Y, the yellow photoreceptor 1Y is uniformly charged by a charging device (not shown), and the exposure device 4 irradiates laser light to form an electrostatic latent image. The electrostatic latent image is developed by a developing device (not shown), whereby a yellow toner image is formed on the yellow photoreceptor 1Y. Similarly, in the image forming units 5 (M, C, K) for other colors, magenta, cyan, and black toner images are formed on the respective photoreceptors 1 (M, C, K). As the surface of the intermediate transfer belt 121 moves, the color toner images are sequentially transferred by the primary transfer rollers 24 (Y, M, C, K) to form a composite color image on the intermediate transfer belt 121. Note that the image forming operation for each color is executed while shifting the timing from the upstream side toward the downstream side so that the toner image is transferred to the same position on the intermediate transfer belt 121.

  On the other hand, the transfer paper P is fed from the paper feed cassette 2 a to the paper transport path 22 by the paper feed roller 27 and transported to the secondary transfer nip portion formed by the intermediate transfer belt 121 and the secondary transfer roller 23. Then, the composite color image on the intermediate transfer belt 121 is transferred by the secondary transfer roller 23 to transfer the color image onto the transfer paper P. The transfer paper P after the image transfer is sent to the fixing device 8 to fix the transferred image. The transfer paper P that has been subjected to the fixing process in the fixing device 8 is stacked on the paper discharge tray 30 by the paper discharge roller 26 or in the double-sided cover 31 in order to form a toner image on the other surface. Any one of the transport modes to be sent to the reverse transport unit is selected.

  Further, the residual toner on each photoconductor 1 (Y, M, C, K) after the toner image transfer is cleaned by the respective cleaning devices. Further, the residual toner on the intermediate transfer belt 121 after the toner image is transferred is cleaned by an intermediate transfer belt cleaning device (not shown). Waste toner collected from each photoconductor 1 (Y, M, C, K) is discharged from a waste toner bottle 300 provided in the copier 500 by a waste toner conveying screw (not shown) provided in each cleaning device. To be discharged. The waste toner collected from the intermediate transfer belt 121 is discharged to a waste toner bottle 300 provided in the copier 500 by a belt waste toner conveying screw (not shown) in the intermediate transfer belt cleaning device.

  Also, each developing device that has consumed toner by image formation is illustrated from toner bottles 7 (Y, M, C, K) filled with yellow, magenta, cyan, and black toners in the upper left of FIG. The toner is replenished to each color developing device by a predetermined replenishment amount through the non-conveying path. The arrangement order of the four image forming units 5 (Y, M, C, K) and the toner bottles 7 (Y, M, C, K) is not limited to the example shown in FIG.

  When the copying machine 500 according to the present embodiment copies a document (not shown), for example, a sheet-like document is set on a document table (not shown) of the scanner 3. When a copy start switch (not shown) is pressed after the original is set, the original reading operation by the scanner 3 is started. In the document reading operation, first, a first traveling body and a second traveling body (not shown) start traveling, and light is emitted from a light source provided on the first traveling body. Then, the reflected light from the document surface is reflected by a mirror provided in the second traveling body, passes through an imaging lens (not shown), and enters a reading sensor (not shown). Then, the reading sensor constructs image information based on the incident light.

  In parallel with the document reading operation, each device in each image forming unit 5 (Y, M, C, K), the intermediate transfer unit 120, the secondary transfer roller 23, and the fixing device 8 start driving. Then, based on the image information read by the scanner 3, the exposure device 4 is driven and controlled, and Y, M, C, and K toner images are formed on each photoconductor 1 (Y, M, C, K). Is done. These toner images become four-color toner images that are superimposed and transferred onto the intermediate transfer belt 121.

  Further, almost simultaneously with the start of the document reading operation, the paper feeding operation is started in the paper feeding unit 2. In this paper feeding operation, one of the paper feeding rollers 27 is selectively rotated, and the transfer paper P is sent out from one of the paper feeding cassettes 2a accommodated in multiple stages. The transferred transfer paper P is separated one by one by the paper feed roller 27 and enters the paper transport path 28, and is then transported toward the secondary transfer nip by the transport roller pair 29. In some cases, paper is fed from the manual feed tray 50 in place of such paper feeding from the paper feeding cassette 2a. In this case, the manual paper feed roller 51 rotates to feed the transfer paper P on the manual tray 50 and feed the transfer paper P one by one to the manual paper feed path 52.

  In the present embodiment, a double-sided cover 31 including a reverse conveying unit is provided above the paper feeding unit 2 and on the right side surface of the image forming unit 60. Therefore, a space is created below the double-sided cover 31. Thus, if there is a space below the double-sided cover 31, the appearance quality will deteriorate. Further, when carrying the copying machine 500, the double-sided cover 31 may be held instead of the handle and the double-sided cover 31 may be damaged. For this reason, in this embodiment, the blindfold cover 40 is attached below the double-sided cover 31 and on the right side of the sheet feeding unit 2 in the drawing. As a result, the appearance quality is improved, and the double-sided cover 31 is not held instead of the handle when the copying machine 500 is carried.

  The double-sided cover 31 is rotatable with respect to the copier 500 main body about the cover rotation shaft 32, and the user rotates the double-sided cover 31 in the direction of arrow A in FIG. Is exposed. Thereby, when a paper jam occurs in the paper conveyance path 22, the jammed transfer paper P can be easily removed by opening the double-sided cover 31. The double-sided cover 31 includes a guide member (not shown) that forms a part of the paper conveyance path 22 on the back surface of the exterior and guides the transfer paper P that passes through the paper conveyance path 22.

  As an option, the copying machine 500 can be provided with a second paper feeding unit 70 below the paper feeding unit 2 as shown in FIG. When the second paper feeding unit 70 is provided, the blind cover 40 is removed, and the second paper feeding unit 70 is attached at that position. When the blindfold cover 40 is attached to the copier 500 using a fastening member such as a screw, when the optional second paper feeding unit 70 is attached, it is necessary to remove the blindfold cover 40 using a tool such as a screwdriver. Therefore, there arises a problem that the mounting operation of the second paper feeding unit 70 becomes complicated. Moreover, it is necessary to use a plurality of fastening members such as screws for fixing the blindfold cover 40, leading to an increase in the cost of the apparatus. Therefore, in this embodiment, the blindfold cover 40 is fixed to the image forming apparatus main body by snap fitting. As a result, the blindfold cover 40 can be detached from the copying machine 500 without using a tool or the like, and the blindfold cover 40 can be easily detached as compared with the case where the blindfold cover 40 is fixed with a fastening member such as a screw. Moreover, compared with the case where the blindfold cover 40 is attached by a fastening member such as a screw, the number of parts can be reduced, and the apparatus can be made inexpensive.

Next, features of the copying machine 500 of this embodiment will be described.
FIG. 1 is an explanatory perspective view of the copying machine 500. FIG. 1A is an explanatory diagram in which each member of the copying machine 500 is denoted by reference numerals, and FIG. 1B is a diagram illustrating the copying machine 500 in FIG. It is explanatory drawing which showed the part which can be rotated with respect to the oblique line part. Further, in FIG. 1A, the axis center of the cover rotation shaft 32 that is disposed inside the double-sided cover 31 and cannot be confirmed from the appearance is indicated by a one-dot chain line.

The double-sided cover 31 is disposed on the right side surface 500a of the main body of the copying machine 500, and the upper end, which is a moving end, is rotated in a direction to move away from the main body of the copying machine 500. A certain paper conveyance path 22 is exposed.
The copying machine 500 has a right front handle portion 34 that is fixed to the apparatus main body as a handle portion for carrying the apparatus and that is recessed with respect to the right side surface 500a of the exterior of the apparatus main body. The right front handle portion 34 is disposed at a position lower than the lower end of the double-sided cover 31 within the width of the double-sided cover 31 in the width direction of the right side surface 500a (the direction parallel to the Y axis in FIG. 1). Yes.
The width of the double-sided cover 31 is not limited to one in which the entire width direction of the right-hand front handle portion 34 fits within the width of the double-sided cover 31. It only needs to be located within the width.

Here, the handle for carrying the apparatus in the conventional image forming apparatus will be described.
Handles for transporting the apparatus are installed in the vicinity of the four corners of the apparatus main body, and a double-sided cover 31 having a paper conveyance path on the back surface is disposed at one of the four corners (the right front corner in the copying machine 500). Exists.

  FIG. 9 is an explanatory diagram of a copying machine 500 in which a right front handle portion 34 including a concave handle portion is provided next to the width direction of the double-sided cover 31 (a direction parallel to the Y axis in the drawing). FIG. 9A is an explanatory diagram in which each member of the copying machine 500 is denoted by reference numerals. FIG. 9B is a diagram illustrating the copying machine 500 in FIG. It is explanatory drawing which showed the part which can be rotated with respect to the oblique line part.

  In the copying machine 500 shown in FIG. 9, the cover rotation shaft 32 that is a support shaft of the double-sided cover 31 is fixed to the main body front side plate 501. For this reason, as a space in which the right front handle portion 34 is arranged, only a space in front of the cover rotation shaft 32 inserted into the main body front side plate 501 can be secured. In order to stably hold the copying machine 500 when the apparatus is transported, the fingers of four hands from the index finger to the little finger need to enter the recess of the handle portion. However, if the space for arranging the right front handle portion 34 is narrow, there is a problem that only one to three fingers can enter the recess of the right front handle portion 34.

  FIG. 10 is an explanatory diagram of a copying machine 500 in which a double-sided cover 31 itself is provided with a right front handle portion 34 formed of a hollow handle portion. FIG. 10A is an explanatory diagram in which each member of the copying machine 500 is provided with a reference numeral. FIG. 10B illustrates the copying machine 500 in FIG. It is explanatory drawing which showed the part which can be rotated with respect to the oblique line part.

  As shown in FIG. 10, when the handle portion is provided on the double-sided cover 31 itself, a load is applied to the hinge portion of the double-sided cover 31 such as the cover rotating shaft 32 when the apparatus is transported, and this hinge portion may be damaged. As shown in FIG. 10, the structure in which the handle portion is provided on the double-sided cover 31 itself is employed when the copying machine 500 itself has a relatively light weight and a small load due to the weight.

  FIG. 11 shows a rod-shaped handle portion that can be inserted into and removed from the casing forming the right side surface 500a of the copying machine 500 main body next to the width direction of the double-sided cover 31 (the direction parallel to the Y axis in the figure). 3 is an explanatory diagram of a copying machine 500 provided with a lever 100. FIG. FIG. 11A is an explanatory diagram in which each member of the copying machine 500 is denoted by reference numerals, and FIG. 11B is a diagram illustrating the copying machine 500 in FIG. It is explanatory drawing which showed the part which can be rotated with respect to the oblique line part. The transport lever 100 is slidable in the direction of arrow B in FIG. 11A (direction parallel to the X axis in the figure). Further, FIG. 11A shows a state in which the transport lever 100 is protruded, and FIG. 11B shows a state in which the transport lever 100 is housed. The transport lever 100 can be taken in and out in the direction orthogonal to the right side surface 500a along the rod-like longitudinal direction.

  FIG. 12 is an explanatory diagram of a digging handle portion 37 having a hollow shape used for the right front handle portion 34 of the copier 500 of this embodiment, the right back handle portion 35 of the copier 500 shown in FIG. . 12A is an XZ sectional view of the digging handle portion 37 as viewed from the side of the right side surface 500a (front side of the copying machine 500), and FIG. 12B is a digging handle portion. 37 is an external view of the right side surface 500a viewed from the front (side surface of the copying machine 500).

  FIG. 13 is an explanatory diagram of the transport lever 100 used in the handle portion on the right front side of the copying machine 500 shown in FIG. 13A is an XZ sectional view of the transport lever 100 as viewed from the side of the right side surface 500a (front side of the copying machine 500), and FIG. 13B is a right side view of the transport lever 100. FIG. 5 is an external view of 500a as viewed from the front (side surface of copying machine 500).

In FIG.12 and FIG.13, in each handle part (37 and 100), the part which a hand contacts at the time of apparatus conveyance is shown with the dashed-dotted line.
As shown in FIG. 12, the digging handle portion 37 carries the apparatus main body by placing a hand on the hollow shape formed on the exterior cover of the copying machine 500 main body. On the other hand, in the configuration including the handle portion including the transport lever 100 shown in FIG. 13, when transporting the apparatus, the transport lever 100 is slid from the housing of the apparatus main body and pulled out to a fixed position. The apparatus main body is transported by grasping the pulled transport lever 100 with a hand.

  The rod-shaped handle portion pulled out from the apparatus main body like the transport lever 100 shown in FIG. 13 has a length that extends sufficiently from the index finger to the little finger of the human hand as the length of the rod-shaped longitudinal direction (arrow B direction in the figure). Is necessary. However, the rod-shaped diameter only needs to be long enough to support the lower part between the first joint and the second joint of the finger of a human hand (around 2 [cm]). Since the width required to arrange the rod-shaped handle portion having such a diameter is narrower than the digging type handle portion 37 shown in FIG. 12, it is possible to suppress an increase in the width of the right side surface 500a.

  However, in the case of a configuration including a rod-like handle portion that is pulled out from the apparatus main body like the transport lever 100 shown in FIG. 13, it is necessary to pull out the handle portion from the apparatus main body when the apparatus is transported, and the workability during transport is poor.
