Abstract: An apparatus is provided for automatically delivering a glass sheet for a preparation. The apparatus including a rack for receiving a stack of glass sheets, rollers for feeding out a lowest glass sheet until the lowest glass sheet has been completely ejected from the stack, and a switch mechanism capable of terminating the operation of the rollers by the contact of the leading edge of the lowest glass sheet. The roller includes a plurality of protrusions for pushing the trailing edge of the lowest glass sheet in order to operate the switch mechanism by the contact of the leading edge when the lowest glass sheet has been completely ejected from the stack. The switch mechanism can reliably be operated by the force of the pushing operation.

Abstract: A container for containing a plurality of glass sheets in a stacked manner has at its bottom an opening through which rollers whose outer peripheries are polygonal and circular in section, respectively, are brought into contact with the undermost glass sheet. The container further has a glass sheet delivery slit with an opening height larger than the thickness of one glass sheet and smaller than the combined thickness of two glass sheets. The rotation of the two rollers causes the glass sheets to be vertically displaced to weaken the adsorptive force between the adjacent glass sheets and to be vibrated to weaken the frictional force between adjacent glass sheets. This results in a frictional force between the two rollers and the undermost glass sheet larger in magnitude than a frictional force between the adjacent glass sheets, which enables the undermost one of the glass sheets being stacked within the container to horizontally displace with the aid of the two rotating rollers.
