         7 . The bag storage case according to  claim 6 , wherein the third wall comprises a first inclined part and a second inclined part, the take-out opening being formed in the first inclined part. 
     
     
         8 . The bag storage case according to  claim 6 , wherein the holder comprises a tray and a holding part, the holding part including a shaft that is configured to be received in the folded portion of the plurality of stacked and folded bags. 
     
     
         9 . The bag storage case according to  claim 8 , wherein the holding part includes a support plate configured to support a first side of the plurality of stacked and folded bags. 
     
     
         10 . The bag storage case according to  claim 9 , wherein the support plate is at an angle to the pair of first walls when the holder is inserted into the housing. 
     
     
         11 . The bag storage case of  claim 8 , wherein the holding part includes an adjusting member configured to bias the folded portion toward the take-out opening. 
     
     
         12 . The bag storage case according to  claim 9 , wherein the tray includes a hanging part configured to a second side of the plurality of stacked and folded bags. 
     
     
         13 . The bag storage case according to  claim 12 , wherein the hanging part includes a cylindrical part and a flange at an end of the cylindrical part, the cylindrical part being configured to inserted into a hole in the plurality of stacked and folded bags, and the flange having a diameter larger than a diameter of the hole. 
     
     
         14 . The bag storage case according to  claim 6 , wherein the holder further comprises a guide part comprising a pair of projections that are configured to engage opposing sides of a bag from the plurality of stacked and folded bags being withdrawn through the take-out opening. 
     
     
         15 . The bag storage case according to  claim 6 , wherein the first width of the take-out opening is a function of the second width of the plurality of stacked and folded bags. 
     
     
         16 . The bag storage case according to  claim 15 , wherein the function is a linear function. 
     
     
         17 . The bag storage case according to  claim 16 , wherein the second width of the plurality of stacked and folded bags is Fs and the fist width of the take-out opening is Tw and Tw=0.68Fs+2.2.
