Abstract

A feeding device to feed a sheet in a feeding direction includes a mount on which a substantially rectangular parallelepiped sheet pack is mountable; a first cutter to cut, in the feeding direction, a first side surface on one end side in a width direction orthogonal to the feeding direction out of four side surfaces of the sheet pack; a second cutter to cut, in the width direction, a second side surface on a downstream side in the feeding direction out of the four side surfaces; and a third cutter to cut, in the feeding direction, a third side surface on another end side in the width direction out of the four side surfaces. Height positions cut by the first cutter, the second cutter, and the third cutter coincide with each other. Cut portions by the first cutter, the second cutter, and the third cutter are coupled to each other.

Dependent claims

A feeding device to feed a sheet in a feeding direction, the feeding device comprising:

a mount on which a substantially rectangular parallelepiped sheet pack including a sheet bundle and a wrapping material wrapping the sheet bundle is mountable;
a first cutter to cut, in the feeding direction, an upper portion and a lower portion of a first side surface located on one end side of the sheet pack in a width direction orthogonal to the feeding direction out of four side surfaces of the sheet pack mounted on the mount;
a second cutter to cut, in the width direction, an upper portion and a lower portion of a second side surface located on a downstream side of the sheet pack in the feeding direction out of the four side surfaces of the sheet pack mounted on the mount;
and
a third cutter to cut, in the feeding direction, an upper portion and a lower portion of a third side surface located on another end side of the sheet pack in the width direction out of the four side surfaces of the sheet pack mounted on the mount,
wherein a height position cut by the first cutter, a height position cut by the second cutter, and a height position cut by the third cutter coincide with each other,
the feeding device further comprising:
a pair of side fences to determine a position in the width direction of the sheet pack mounted on the mount;
and
a reference fence to determine a position on the downstream side in the feeding direction of the sheet pack mounted on the mount,
wherein:
the first cutter is to move along a first guide extending in the feeding direction on a first side fence located on one end side in the width direction out of the pair of side fences,
the second cutter is to move along a second guide extending in the width direction on the reference fence, and
the third cutter is to move along a third guide extending in the feeding direction on a second side fence located on another end side in the width direction out of the pair of side fences.
