1. A vacuum cleaner comprising: a body case defining a chamber having at least one opening at one end, said body case further defining an air outlet opening communicating with said chamber; an electric-powered blower secured in said body case; a dust case defining a coarse dust collecting chamber open at both ends; means for releasably securing said body case to said dust case with one open end of said dust case in abutting confronting relation with said one end of said body case; a primary air permeable filter secured in said dust case so as to partially define said coarse dust collecting chamber; a lid having an air intake therein; and means for hingedly securing said lid to said dust case for movement between a closed position wherein the other open end of said dust case is covered by said lid and an open position wherein said other open end is exposed; a filter housing unit defining a fine dust collecting chamber; a second air permeable filter secured in said filter housing unit; and means for hingedly attaching said filter housing unit to said dust case for movement between a first position wherein said housing unit overlies said one open end of said dust case, and a second position wherein said one open end is exposed, said housing unit having an opening therein for communicating said coarse dust collecting chamber with said fine dust collecting chamber when said housing unit is in said first position, whereby when said lid is in said closed position and said housing unit is in said first position and said electric-powered blower is activated, air is drawn through said air intake into said coarse dust collecting chamber, through said primary air filter, through said fine dust collecting chamber, into said body case chamber through said second filter, and out through said air outlet opening. 2. The vacuum cleaner of claim 1, wherein said one open end of said dust case is located substantially opposite said lid. 3. The vacuum cleaner of claim 1, further comprising an air permeable dust bag having a bag mouth plate; and wherein said lid includes bag mouth plate fitting means for receiving said mouth plate of said dust bag. 4. The vacuum cleaner of claim 3, wherein said bag mouth plate is made of paper. 5. The vacuum cleaner of claim 3, and further comprising bag mouth holding means for releasably securing said dust bag to said fitting means, and said filter housing unit including means cooperating with said holding means for releasing said dust bag from said fitting means. 6. The vacuum cleaner of claim 5, wherein said dust bag releasing means comprises a linkage member extending above said primary filter and operating in response to movement of said filter housing unit to said second position. 7. The vacuum cleaner of claim 1, wherein said filter housing unit comprises a partition plate, and wherein said partition plate overlies said one open end of said dust case when said filter housing unit is in said first position. 8. A vacuum cleaner comprising: a body case defining a chamber having at least one opening at one end, said body case further defining an air outlet opening communicating with said chamber; an electric powered blower secured in said body case; a dust case defining a coarse dust collecting chamber open at both ends; means for releasably securing said body case to said dust case with one open end of said dust case in abutting confronting relation with said one end of said body case; a primary air permeable filter secured in said dust case so as to partially define said coarse dust collecting chamber; a lid having an air intake therein; and means for hingedly securing said lid to said dust case for movement between a closed position wherein the other open end of said dust case is covered by said lid and an open position wherein said other open end is exposed, the inner surface of said lid including a bag-mouth plate fitting means for receiving a dust bag when used; a housing unit defining a fine dust collecting chamber; means for hingedly attaching said housing unit to said dust case for movement between a first position wherein said housing unit overlies said one open end of said dust case and a second position wherein said one open end of said dust case is exposed, said housing unit having an opening therein for communicating said fine and coarse dust collecting chambers when said housing unit is in said first position; and bag-mouth holding means for releasably securing said dust bag when used to said fitting means; and said housing unit defining means cooperating with said bag-mouth holding means for releasing the dust bag when used from the mouth plate fitting means to permit removal of said dust bag through said one end of said dust case when said dust case is released from said body case. 9. The vacuum cleaner of claim 8, further comprising a second filter secured in said housing unit. 10. The vacuum cleaner of claim 8, wherein said one open end of said dust case is located substantially opposite said lid. 11. The vacuum cleaner of claim 8, further comprising an air permeable dust bag having a bag mouth plate dimensioned for receipt by said fitting means. 12. The vacuum cleaner of claim 11, wherein said bag mouth plate is made of paper. 13. The vacuum cleaner of claim 8, wherein said housing unit comprises a partition plate, and wherein said partition plate overlies said one open end of said dust case when said housing unit is in said first position. 14. The vacuum cleaner of claim 13, wherein said dust bag releasing means comprises a linkage member extending above said primary filter and operating in response to movement of said housing unit to said second position. 15. The vacuum cleaner of claim 8, wherein said dust bag releasing means comprises a linkage member extending above said primary filter and operating in response to movement of said housing unit to said second position.
