Abstract: Provided is a supply chain optimization system and a method for optimizing a supply chain that can prevent a production delay due to the lack of materials and a shipment delay due to the lack of stock products even if a sales plan fluctuates on an increase in sales of the supply chain as a whole and that can optimize the stocks of the products and materials and a physical distribution route of product supplies. The supply chain optimization system and the method for optimizing the supply chain calculate through a simulation in which a supply chain model is used so that a total sum of stock costs for products and materials and logistics costs therefor are minimized with respect to the number of stock products and materials which do not cause product defects at a fluctuation time of a sales plan on a condition in which the stock products increased in accordance with the fluctuation of the sales plan are set to factory stocks.

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.

Abstract: An ink cartridge used in an inkjet recording apparatus, including and ink storing section having an ink outlet section, and an outer case, wherein the outer case includes a casing section to store the ink storing section, a positioning member to secure the ink outlet section, a first cushioning member to support a top of the ink storing section, a second cushioning member to support a bottom of the ink storing section, and a securing member to secure at least a part of the ink storing section onto the outer case.

Abstract: An ink cartridge for inkjet recording apparatus including: an ink pack including an ink feeding section of thermoplastic resin; a bag-like ink accommodation section of multilayer thermoplastic film materials; an ink filled in said ink pack; a positioning control member for controlling a position of said ink feeding section; and an outer box for accommodating said ink pack, wherein said ink feeding section comprises a hollow cylindrical ink feeding tube including: a joint section for jointing with said ink accommodation section; a positioning control means accommodated in said positioning control member; a first opening through which an ink supply means in said inkjet recording apparatus can be inserted and pulled out; a second opening for supplying said ink to said inkjet recording apparatus from said ink accommodation section via said first opening; and a cover for opening said second opening by inserting said ink supply means and for closing said second opening by pulling out said ink supply means, and wher
