Description

  The present invention relates to an image forming apparatus in which a handle for transportation is provided in an apparatus main body.

  Conventionally, there is known an image forming apparatus in which a handle for transportation is provided on an apparatus main body as described in Patent Document 1. The image forming apparatus includes an apparatus main body unit in which an image forming unit that performs an image forming process on a sheet is provided, a document processing unit that is stacked on the apparatus main body so as to read the image from an original, the apparatus main unit, and the original And an in-body paper discharge unit for receiving the transfer-finished paper interposed between the processing unit and the processing unit. The handle is formed of a rod, and is attached to the four corners of the upper part of the frame (hereinafter referred to as a main body frame) of the apparatus main body having a rectangular parallelepiped shape so as to be able to appear and retract.

  Such a handle is usually immersed in the main body frame, but is pulled out of the main body frame when the image forming apparatus is moved. Then, the image forming apparatus is carried by holding the pulled handle.

  By the way, in recent years, image forming apparatuses have been made more compact, and those having a size that can be carried and carried by one person have appeared. When such a small image forming apparatus is placed directly on the floor, it is easier to carry the handle if the handle is positioned as high as possible without having to bend. preferable. When the image forming apparatus disclosed in Patent Document 1 is viewed from this point of view, the handle is provided at the uppermost part of the main body frame, so it is certainly easier to carry than when the handle is directed at a lower position. However, depending on the size of the apparatus main body, it may be preferable to provide it further upward.

Therefore, it is conceivable to provide a handle on the frame of the document processing unit. By doing so, even when a small image forming apparatus is placed directly on the floor, the image forming apparatus can be carried more easily through the handle with almost no bending.

  However, the document processing unit of the image forming apparatus is configured to scan the document surface with light emitted from a light source and input the reflected light to a CCD (Charge Coupled Device) through a plurality of mirrors. An image reading apparatus that optically reads an original image is employed. Since this image reading apparatus is a very delicate precision device, when the image forming apparatus is carried through a handle provided on the frame of the document processing unit and the frame is slightly deformed, As a result, the constituent devices of the image reading apparatus are slightly displaced, and this causes a deviation in the optical path of the reflected light, resulting in inconvenience that accurate image reading processing cannot be performed.

  SUMMARY OF THE INVENTION The present invention has been made in order to solve the conventional inconvenience, and it is an object of the present invention to provide an image forming apparatus capable of easily carrying the apparatus main body while ensuring accurate image reading processing. Yes.

  According to the first aspect of the present invention, a lower frame in which an image forming unit for performing an image forming process is provided, an intermediate frame mounted in a stacked state on the top of the lower frame, and the intermediate frame supported by the lower frame. And an upper frame provided with an image reading unit for optically reading a document image, and the intermediate frame is a pair of opposed side surfaces constituting a part of a side wall portion of the apparatus main body. The image forming apparatus is characterized in that at least a pair of handles for lifting and carrying the apparatus main body is provided on the opposite side surface.

  According to such a configuration, the handle for carrying the image forming apparatus is provided on the opposite side surface of the intermediate frame that is located above the lower frame and can support the upper frame. Thus, it is possible to easily carry the image forming apparatus through the handle while ensuring accurate image reading processing.

  According to a second aspect of the present invention, in the first aspect of the present invention, the handle is formed by forming a concave portion or the same portion formed by recessing a part of the wall surface of the intermediate frame. It is formed by the made opening.

  According to such a configuration, the handle is formed by a recess or an opening provided on the wall surface, so that it does not get in the way compared to a handle protruding to the outside. In addition, the handle is not a complicated structure like a conventional handle configured to be able to appear and retract with respect to the apparatus main body, and is formed at a low cost.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the intermediate frame is provided with a discharge tray on the upper surface thereof for receiving a transfer material discharged from the toner image transferred by the image forming unit. It is characterized by that.

  According to such a configuration, by providing the discharge tray on the upper surface of the intermediate frame, the central portion of the intermediate frame is recessed, and the peripheral portion becomes a support portion for supporting the upper frame. Since the intermediate frame is structurally strong, deformation of the upper frame supported by the intermediate frame is effectively prevented.

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein a reinforcing rib is provided in the vicinity of the position where the handle is provided in the intermediate frame. It is what.

  According to such a configuration, the intermediate frame is in a state where the vicinity of the handle is structurally reinforced by the ribs, and therefore, it resists stress concentration in the vicinity of the handle when the image forming apparatus is lifted by hand through the handle. You can get it.

  The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the opposite side surface of the intermediate frame is located at a position higher than half of the total height of the apparatus main body. is there.

  According to such a configuration, since the center of gravity is located below the handle when the apparatus main body is lifted via the handle, the lifted state is stabilized.

  According to the image forming apparatus of the present invention, the handle for carrying the image forming apparatus is provided in the intermediate frame that is located above the lower frame and can support the upper frame evenly. When the image forming apparatus is moved, the image forming apparatus can be easily carried without causing the inconvenience of bending the waist and lifting the image forming apparatus one by one. Can be prevented, and accurate image reading processing can be ensured even after the image forming apparatus is moved.

  According to the image forming apparatus 10 having such a configuration, when the user moves the image forming apparatus 10, the user is provided in the intermediate frame 60 without doing the inconvenience of bending the waist and lifting the image forming apparatus 10 one by one. Not only can the image forming apparatus 10 be easily carried through the handle 64 provided, but also the inconvenience that the original reading section 20 is deformed by the intermediate frame 60 supporting the upper frame 13 in a stable state. Therefore, accurate image reading processing can be ensured even after the image forming apparatus 10 is carried.

  Since the intermediate frame 60 is provided with an in-body discharge tray 62 for receiving the paper P on which the toner image is transferred and discharged by the image forming unit 30 on the upper surface thereof, the central portion of the intermediate frame 60 is In addition to being depressed, the peripheral portion becomes a support portion for supporting the upper frame 13, and the unevenness can make the intermediate frame 60 structurally strong and supported by the intermediate frame 60. It is possible to effectively prevent the upper frame 13 from being deformed.

  Further, since a reinforcing rib 611a is provided in the vicinity of the position where the handle 64 is provided in the intermediate frame 60 (specifically, the side plate portion 611), the image forming apparatus can be manually operated via the handle 64.
