1. A sheet dispensing device comprising:
a casing capable of housing a rolled sheet inside and including a sheet dispensing port which is formed at a predetermined height position to face downward and through which the sheet passes when fed out; and
a sheet feeding mechanism which is provided in the casing, wherein, when the sheet dispensing device is used, the sheet feeding mechanism feeds out a predetermined length for use of the sheet from the sheet dispensing port, and dispenses the predetermined length for use, in a hanging state from the sheet dispensing port while holding a part, of the sheet, located upstream of the sheet dispensing port in terms of a feeding direction of the sheet;
the sheet feeding mechanism further comprising:
a driving roller which is disposed upstream of the sheet dispensing port in terms of the feeding direction of the sheet and around whose outer peripheral surface the sheet is wound;
a driven roller which faces the driving roller to sandwich the sheet between the driven roller and the driving roller; and
a drive control part which rotates the driving roller in such a direction as to feed the sheet toward the sheet dispensing port;
wherein the driven roller is supported by an elastic member to be elastically biased in a direction in which the driven roller approaches the driving roller, and, when the driving roller stops rotating, the part located upstream of the sheet dispensing port in terms of the feeding direction of the sheet is held while sandwiched between the driving roller and the driven roller;
wherein the drive control part includes a feed amount detecting part which controls an amount of the sheet fed per time to control the predetermined length for use that is to be hung down from the sheet dispensing port;
wherein the sheet has cutting lines extending between edges of the sheet and formed at predetermined intervals in the feeding direction; and
wherein the drive control part stops driving the driving roller when the feed amount detecting part detects a predetermined number of the cutting lines in the feeding direction after the driving roller starts rotating;
the sheet dispensing devise further comprising:
a resistance applying part which applies a predetermined resistance to the sheet to widen slits forming the cutting lines when the sheet is transferred toward the sheet dispensing port;
a sheet cartridge disposed in the casing, housing the rolled sheet, and including a cover having a pullout port from which the sheet is pulled out, wherein an elastic contact piece which comes into contact with the sheet is provided as the resistance applying part at the pullout port; and
a fracture preventing auxiliary roller provided between the elastic contact piece and the driving roller to prevent a fracture along the cutting line.
