Image forming system and a method for loading sheet films

Abstract

An image forming system includes: (1) an image forming apparatus and (2) a film package having a plurality of photosensitive sheet films and a light shielding bag that packs the plurality of photosensitive sheet films. Herein, the light shielding bag includes a bag section, a cut section to be cut at a first end portion of the bag section, and a holding section opposite the first end portion; after the cut section is cut, the film package is loaded on the loading section and mounted on the main body of the apparatus, the holding section is pulled from outside to take out the bag from the apparatus, and the photosensitive sheet films remain loaded on the loading section; and a length of the holding section outside the main body of the apparatus is smaller than or equal to 70 mm.

1 . An image forming system, comprising: 
 (1) an image forming apparatus including:    an image forming section that forms an image on a photosensitive sheet film;    a loading section to load a plurality of photo sensitive sheet films; and    a main body of the apparatus that accommodates the image forming section and the loading section and maintains inside of the main body light shielded; and    (2) a film package including:    a plurality of photosensitive sheet films; and    a light shielding bag that packs the plurality of photosensitive sheet films,    wherein,    the light shielding bag includes a bag section, a cut section to be cut at a first end portion of the bag section, and a holding section provided at a second end portion of the bag section opposite the first end portion;    after the cut section is cut, the film package is loaded on the loading section and mounted on the main body of the apparatus, the holding section is pulled from outside so that the bag is taken out of the main body of the apparatus, and the plurality of photosensitive sheet films remain loaded on the loading section; and    a length of the holding section that is outside the main body of the apparatus and pulled is smaller than or equal to 70 mm.    
   
   
       2 . The image forming system of  claim 1 , wherein a buffer member is provided at a bottom of the main body of the apparatus, the buffer member having a high friction coefficient and being capable of damping vibration transmission.  
   
   
       3 . The image forming system of  claim 1 , wherein the loading section is movable between a sheet film loading position and a film feed-out position in the apparatus.  
   
   
       4 . The image forming system of  claim 1 , wherein the system is a desktop type.  
   
   
       5 . The image forming system of  claim 1 , wherein the holding section has a flat shape having no portion through which to hook a finger.  
   
   
       6 . The image forming system of  claim 1 , wherein the film package is held such that a force to pull out the light shielding bag does not exceed 147 N.  
   
   
       7 . The image forming system of  claim 1 , comprising a guide to guide the light shielding bag to be pulled out such that the pulling direction of the light shielding bag is upward than horizontal.  
   
   
       8 . The image forming system of  claim 1 , wherein a weight of the main body of the apparatus is in a range from 60 to 70 kg.  
   
   
       9 . The image forming system of  claim 1 , wherein a sheet film is exposed with an exposing device, while being developed by a developing device at a front end side of the exposing device.  
   
   
       10 . A sheet film loading method of loading a plurality of photosensitive sheet films by loading a film package comprising a light shielding bag that stores the plurality of light shielding films to a loading section of an image forming apparatus, cutting a cut section provided at an end portion of the light shielding bag, thereafter setting a length of a holding section that is disposed at another end portion and for pulling out the light shielding bag from outside to smaller than or equal to 70 mm.
