Image forming apparatus provided with post-processing device

Abstract

An image forming apparatus comprises a main body, a post-processing device, an objective working section, a light source and a shade member. The post-processing device is disposed freely displaceable between a retracted position at which it is received by an intra-body paper discharge section of the main body and a protruded position at which it is drawn to one side face side. The objective working section is disposed on an upstream side face of the post-processing device in the drawing direction of the post-processing device. The light source is disposed on the upstream side face of the post-processing device, and lights up the objective working section at the protruded position. The shade member is disposed on the upstream side face of the post-processing device and in the front face side from the light source, and blocks direct projection light of the light source to the front face side.

What is claimed is: 
     
       1. An image forming apparatus comprising:
 a main body including an intra-body paper discharge section, the intra-body paper discharge section being provided in a space sandwiched between upside and downside respectively, by an image reading section for reading an image of a document and generating a set of image data, and an image forming section for performing an image forming process on a recording medium based on the set of image data; the intra-body paper discharge section being whereto the recording medium that has undergone the image forming process is discharged; 
 a post-processing device disposed so as to be freely displaceable between a retracted position at which it is received by the intra-body paper discharge section and a protruded position at which it is drawn to one side face side; the post-processing device, at the retracted position, being adapted for performing a process on the recording medium that has undergone the image forming process; 
 an objective working section disposed on an upstream side face of the post-processing device in the drawing direction of the post-processing device, the objective working section being whereto a maintenance task is carried out at the protruded position; 
 a light source disposed on the upstream side face and having a function to light up the objective working section at the protruded position; and 
 a shade member disposed on the upstream side face and in the front face side from the light source for blocking off direct projection light to the front face side of the light source, wherein a dimension in height of the shade member is configured so as to be larger than a dimension in height of the light source, and the shade member projects more than the light source on the upstream side face. 
 
     
     
       2. The image forming apparatus as claimed in  claim 1 , wherein the light source is disposed toward a rear face side on the upstream side face and in the front face side from the objective working section. 
     
     
       3. The image forming apparatus as claimed in  claim 1 , wherein the light source is a white LED. 
     
     
       4. The image forming apparatus as claimed in  claim 1 , wherein a reflection member for reflecting light emitted from the light source is disposed on at least part of an inner face of the intra-body paper discharge section. 
     
     
       5. The image forming apparatus as claimed in  claim 4 , wherein the reflection member is configured with a white member. 
     
     
       6. The image forming apparatus as claimed in  claim 1 , the apparatus further comprising a control section for controlling lighting conditions of the light source depending on the details of the maintenance task needed for the objective working section. 
     
     
       7. The image forming apparatus as claimed in  claim 1 , wherein the objective working section is a staple cartridge for containing staples to bind the recording media. 
     
     
       8. An image forming apparatus comprising:
 a main body including a front opened space sandwiched, along a vertical direction, by an image reading section for reading an image of a document and generating an image data, and an image forming section for performing an image forming process on a recording medium;   a post-processing device configured to be retracted into and protruded from the front opened space;   an objective working section disposed on an upstream side face of the post-processing device in the drawing direction of the post-processing device, the objective working section being whereto a maintenance task is carried out at the protruded position;   a light source disposed on an inside wall of the front opened space; and   a shade member disposed on the inside wall and in a front side of the light source for blocking off light emitted from the light source, wherein   a height of the shade member is larger than a height of the light source, and the shade member projects more than the light source from the inside wall.   
     
     
       9. The image forming apparatus according to claim 8, wherein a lighting status of the light source is changed according to a status of the image forming apparatus. 
     
     
       10. The image forming apparatus according to claim 8, wherein a lighting status of the light source notifies a status of the image forming apparatus. 
     
     
       11. An image forming apparatus comprising:
 a main body including a front opened space sandwiched, along a vertical direction, by an image reading section for reading an image of a document and generating an image data, and an image forming section for performing an image forming process on a recording medium;   a post-processing device allowed to be retracted into and protruded from the front opened space   an objective working section disposed on an upstream side face of the post-processing device in the drawing direction of the post-processing device, the objective working section being whereto a maintenance task is carried out at the protruded position;   a light source disposed on an inside wall of the front opened space and including a plurality of LEDs; and   a shade member disposed on the inside wall and in a front side of the light source for blocking off light emitted from the light source, wherein   a height of the shade member is larger than a height of the light source, and the shade member projects more than the light source from the inside wall.   
     
     
       12. The image forming apparatus according to claim 11, wherein a lighting status of the light source is changed according to a status of the image forming apparatus. 
     
     
       13. The image forming apparatus according to claim 11, wherein a lighting status of the light source notifies a status of the image forming apparatus.
