Provided are an article advancing device and an article arrangement shelf, wherein the article advancing device has a flexible sheet on which articles can be arranged at a condition where the sheet is extended, a roller to which one end of the sheet is fixed and which winds the sheet in the reverse extension direction, a drive means which rotates the roller in the winding direction of the sheet, and a wall member with which the articles in the first row of the articles arranged on the sheet come into contact. When the articles are arranged on the sheet, the article advancing device stops the winding operation of the sheet by the drive means by the contact of the articles in the first row with the wall member. The article advancing device has a simple article advancing function which employs a horizontally extending shelf basically having no incline and which does not require energy, such as electric power, and can be used regardless of the packaging state of the articles.

1. An article advancing device comprising a flexible sheet on which articles can be arranged at a condition where said sheet is extended, a roller to which one end of said sheet is fixed and which winds said sheet in a reverse sheet-extension direction, a driver that rotates said roller in a winding direction of said sheet, a wall with which articles present in a first row of said articles arranged on said sheet come into contact, a winding operation of said sheet by said driver is stopped by contact of said articles in said first row with said wall when said articles are arranged on said sheet, and an attacher below said wall that attaches to a shelf part of an article arrangement shelf, said attacher comprising a clamp into which an end of said shelf part is fitted attaching said article advancing device to said end of said shelf part, wherein a movable platform is connected to another end of said sheet, andwherein a connector between said sheet and said movable platform comprises a sheet holder with a modified cross-sectional shape which is wrapped with said one end of said sheet around an outer circumference of said sheet holder, and a retainer which has an opening permitting said sheet to pass through in a condition where said sheet is folded and retains said sheet holder wrapped with said one end of said sheet relative to an extending direction of said sheet itself. 2. The article advancing device according to claim 1, wherein said driver uses a spring force as a driving force. 3. The article advancing device according to claim 1, wherein said driver has a driving force adjuster which can adjust a driving force. 4. The article advancing device according to claim 1, wherein said driver has a driving force adjuster which can adjust a driving force, wherein said roller comprises a drive spring which is biased to enable adjustment of a driving force, a first assembly which supports one end of said drive spring and winds up said sheet by rotation, and a second assembly which supports another end of said drive spring and rotates independently of said first assembly, said driving force adjuster comprises a dial, that is rotatably supported on a roller-end cover and is connected to said second assembly to rotate integrally with said second assembly, and a lock spring that biases said dial against said roller-end cover, andsaid driving force adjuster is configured to prevent adjustment of said driving force when said dial is biased against said roller-end cover by a biasing force when said dial is biased against said roller-end cover by a biasing force of said lock spring, and to permit adjustment of said driving force when said dial is spaced from said roller-end cover against said biasing force of said lock spring. 5. The article advancing device according to claim 1, wherein said article advancing device further comprises an interrupter that stops operation of said sheet toward said winding direction. 6. The article advancing device according to claim 1, wherein a sheet lifter through which said sheet can pass at a condition where said sheet is lifted is provided for said sheet at a position near said roller. 7. The article advancing device according to claim 1, wherein a rotating element rotating in a moving direction of said movable platform or a linear element extending in a moving direction of said movable platform is provided to said movable platform. 8. The article advancing device according to claim 1, wherein a cross-sectional shape of at least a part of said sheet holder at a position of a sheet extending-direction side is formed as a polygonal shape, and a section of an inner surface of said retainer up to said opening is formed as a shape along said polygonal shape. 9. An article arrangement shelf comprising said shelf part formed or attached with said article advancing device according to claim 1. 10. The article arrangement shelf according to claim 9, wherein said roller is provided on a lower surface side of said shelf part. 11. The article arrangement shelf according to claim 9, wherein said shelf part has a rail or a groove for regulating a moving direction of said movable platform. 12. An article advancing device comprising a flexible sheet on which articles can be arranged at a condition where said sheet is extended, a roller to which one end of said sheet is fixed and which winds said sheet in a reverse sheet-extension direction, a drive means for rotating said roller in a winding direction of said sheet, a wall member with which articles present in a first row of said articles arranged on said sheet come into contact, a winding operation of said sheet by said drive means is stopped by contact of said articles in said first row with said wall member when said articles are arranged on said sheet, wherein a movable platform is connected to another end of said sheet, and wherein a connecting part between said sheet and said movable platform comprises a sheet holding member with a modified cross-sectional shape which is wrapped with said one end of said sheet around an outer circumference of said sheet holding member, and a retaining member which has an opening permitting said sheet to pass through in a condition where said sheet is folded and retains said sheet holding member wrapped with said one end of said sheet relative to an extending direction of said sheet itself. 13. The article advancing device according to claim 12, wherein a cross-sectional shape of at least a part of said sheet holding member at a position of a sheet extending-direction side is formed as a polygonal shape, and a section of an inner surface of said retaining member up to said opening is formed as a shape along said polygonal shape.
