BEST MODE FOR CARRYING OUT THE INVENTION
Preferred embodiments of the present invention will be illustratively described in detail below with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention thereto unless otherwise specified. Absent.
[0018]
(First Embodiment)
The first embodiment will be described with reference to FIGS. FIG. 1 is an example of a schematic view of the image forming apparatus according to the first embodiment. FIG. 2 is a perspective view of the sheet post-processing apparatus according to the first embodiment.
[0019]
First, the configuration of the image forming apparatus 1 including the sheet post-processing apparatus 2 shown in FIG. 1 will be briefly described.
[0020]
The image forming apparatus 1 not including the sheet post-processing apparatus 2 is of an electrophotographic type as an example. The image forming apparatus 1 reads a document image using an input device on the upper side, and transmits the signal to a laser scanner.
[0021]
The laser scanner forms a latent image on the photosensitive drum in response to a signal, and the latent image is formed on a toner image by a developing device.
[0022]
On the other hand, a sheet is fed from a lower sheet feeding unit, and a toner image is transferred from the photosensitive drum to the sheet.
[0023]
Then, the toner image is fixed on the sheet by the fixing device, and is discharged from the paper discharge unit 11.
[0024]
Next, the sheet post-processing apparatus 2 will be briefly described.
[0025]
When the sheet on which an image has been formed by the image forming apparatus 1 is discharged from the paper discharge unit 11, the sheet is received from the receiving unit 21 as a sheet transfer unit, and sheet post-processing is performed.
[0026]
The sheet post-processing includes, for example, various sorts such as sheet sorting and classification, binding, and folding.
[0027]
Then, the sheet subjected to the sheet post-processing is stored in the sheet storage unit.
[0028]
In the above configuration, the sheet receiving unit 21 of the sheet post-processing apparatus 2 has a shape protruding toward the image forming apparatus 1, and the sheet discharging unit 11 of the image forming apparatus 1 is configured to receive the sheet 21 of the sheet post-processing apparatus 2. Does not have a space for receiving the sheet post-processing device 2, a gap is generated at a joint portion when the sheet post-processing device 2 and the image forming device 1 are connected.
[0029]
This gap causes a jam when there is a falling object, and also causes a noise.
[0030]
For this reason, in this embodiment, the gap between the joints is filled with the blindfold member 3. The blindfold member 3 has a frame shape formed with a predetermined width on the front, top, and back surfaces of the device. Nothing is formed on the lower surface side of the device, and the blindfold member 3 is an opening.
[0031]
The blind member 3 that fills the gap is fixed to the sheet post-processing device 2 with screws (not shown), and serves as a blind for the receiving portion 21 that protrudes toward the image forming device 1 when the image forming device 1 and the sheet post-processing device 2 are connected. It has the role of preventing falling into gaps and preventing noise.
[0032]
The front side blind portion 3A and the back side blind portion 3B of the blind member 3 are brought into contact with the front side and the back side of the connection surface of the image forming apparatus 1 with the sheet post-processing device 2, respectively, so that the image forming apparatus 1 The sheet post-processing apparatus 2 has a shape such that the sheet post-processing apparatus 2 is connected to a predetermined position, and serves as positioning means.
[0033]
That is, the front-side blind portion 3A and the rear-side blind portion 3B of a predetermined width of the blind member 3 as positioning means come into contact with the connection surface of the image forming apparatus 1 so that the sheet post-processing apparatus 2 is moved to the predetermined position of the image forming apparatus 1. Connect to the position.
[0034]
An opening 3C is formed below the rear-side blindfold 3B of the blindfold member 3. For this reason, even when the sheet post-processing apparatus 2 having the blind member 3 is connected to the image forming apparatus 1 having the exhaust port 12 on the connection surface side with the sheet post-processing apparatus 2, the lower part not covered by the blind member 3 Alternatively, air can be exhausted from the opening 3C.
[0035]
(Second embodiment)
In the second embodiment, as shown in FIG. 3, a blind 3 is provided with a guide 3D1, an upper louver 3E as an opening, and a rear louver 3Ba as an opening.
[0036]
In the present embodiment, the positioning in the sheet width direction can be performed by fitting the cylindrical projection-shaped guide portion 3D1 into the insertion hole on the receiving side of the image forming apparatus 1 (not shown).
[0037]
That is, in the present embodiment, the positioning means has a cylindrical projection-shaped guide portion 3D1 and a not-shown insertion hole, and can be positioned by fitting the guide portion 3D1 into the insertion hole. I have.
[0038]
Further, by providing the louver 3E on the upper surface side of the blindfold member 3 and the louver 3Ba on the rear surface side, the exhaust of the image forming apparatus 1 can be secured from above the upper surface side and the rear side without deteriorating the appearance.
[0039]
(Third embodiment)
In the third embodiment, as shown in FIG. 4, a box in which a blinder member 3 covers the entire peripheral surface of the receiving unit 21 of the sheet post-processing device 2 and a portion facing a contact surface of the image forming apparatus 1 is covered. It has a mold shape. As described above, since the blindfold member 3 has a box shape, the noise leaking from the receiving unit 21 can be reduced.
[0040]
Further, the inside of the box-shaped blindfold member 3 is provided with a sound absorbing material, so that the noise leaking from the receiving portion 21 can be further reduced.
[0041]
Also, in the case of the present embodiment, the blindfold member 3 also has a guide portion 3D2 having a round hole shape as a positioning means and a projection of the image forming apparatus 1 (not shown). The projections can be positioned by fitting.
[0042]
Further, since the louver 3 </ b> E penetrating into the blindfold member 3 is provided on the upper surface side, the exhaust can be secured even when the exhaust port 12 of the image forming apparatus 1 is near the paper discharge unit 11. Of course, when the exhaust port 12 of the image forming apparatus 1 is below the blindfold member 3, the opening 3E may not be provided.
[0043]
【The invention's effect】
As described above, according to the present invention, by providing the blind member in the space of the joint portion, it is possible to fill the gap into which the falling object enters, and to hide the delivery portion of the protruding sheet.
[0044]
Further, by providing the opening in the blindfold member, even when the sheet post-processing apparatus is connected to an image forming apparatus having an exhaust port on the connection side with the sheet post-processing apparatus, the exhaust from the exhaust port can be secured. it can.
[0045]
Further, by making the blind member a box-like shape that completely covers the sheet transfer portion, noise can be further reduced.
