Abstract
Abstract A sheet supplying device supplies a sheet to a sheet supplied apparatus which designates the size and transport direction of the sheet. The sheet supplying device includes a movable cassette for placing the sheet thereon and movable to at least two transport positions so as to transport the sheet therefrom in at least two transport directions, a fixed cassette for placing the sheet thereon and fixed in one transport position so as to transport the sheet therefrom in one transport direction, a transport device for transporting the sheet from each of the movable cassette and the fixed cassette to the sheet supplied apparatus. The sheet supplying device further includes a control device, to which the size of the sheet placed on the movable cassette and the size and transport direction of the sheet placed on the fixed cassette are input, for selecting preferentially the fixed cassette as the cassette from which the sheet is transported by the transport device when the size of the sheet placed on the movable cassette corresponds to the designated size and, at the same time, the size and transport direction of the sheet placed on the fixed cassette correspond to the designated size and transport direction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
268 words
A sheet supplying device for supplying a sheet to a sheet supplied apparatus which designates the size and transport direction of the sheet, comprising: a movable sheet placing means having a plane for placing the sheet thereon and movable to at least two transport positions so as to transport the sheet therefrom in at least two transport directions; a fixed sheet placing means having a plane for placing the sheet thereon and fixed in one transport position so as to transport the sheet therefrom in one transport direction; a transport means for transporting the sheet from each of the movable sheet placing means and the fixed sheet placing means to the sheet supplied apparatus; and a control means, to which the size of the sheet placed on the movable sheet placing means and the size and transport direction of the sheet placed on the fixed sheet placing means are input, for comparing the inputted size of the sheet placed on the movable sheet placing means and the inputted size of the sheet placed on the fixed sheet placing means, setting a flag in case that the compared sizes are same to each other, and selecting preferentially the fixed sheet placing means as the sheet placing means from which the sheet is transported by the transport means with reference to the set flag, when the size of the sheet placed on the movable sheet placing means corresponds to the designated size and, at the same time, the size and transport direction of the sheet placed on the fixed sheet placing means correspond to the designated size and transport direction.
Claim 2
Dependent Claim
268 words
A sheet supplying device for supplying a sheet to a sheet supplied apparatus which designates the size and transport direction of the sheet, comprising: a movable sheet placing means having a plane for placing the sheet thereon and movable to at least two transport positions so as to transport the sheet therefrom in at least two transport directions; a fixed sheet placing means having a plane for placing the sheet thereon and fixed in one transport position so as to transport the sheet therefrom in one transport direction; a transport means for transporting the sheet from each of the movable sheet placing means and the fixed sheet placing means to the sheet supplied apparatus; and a control means, to which the size of the sheet placed on the movable sheet placing means and the size and transport direction of the sheet placed on the fixed sheet placing means are input, for comparing the inputted size of the sheet placed on the movable sheet placing means and the inputted size of the sheet placed on the fixed sheet placing means, setting a flag in case that the compared sizes are same to each other, and selecting preferentially the fixed sheet placing means as the sheet placing means from which the sheet is transported by the transport means with reference to the set flag, when the size of the sheet placed on the movable sheet placing means corresponds to the designated size and, at the same time, the size and transport direction of the sheet placed on the fixed sheet placing means correspond to the designated size and transport direction.
