Abstract
Abstract A device installed in an imsge recording apparatus for pulling out the leading edge of a rolled recording medium such as a rolled paper and then cutting the recording medium at a predetermined length as measured from the leading edge to feed the resulting sheet to a predetermined recording section of the apparatus. A plurality of paper feed mechanisms are each provided with a cutter for cutting a paper which is paid out from a roll. When two or more of the paper feed mechanisms are loaded with a paper of a desired kind, they are automatically and repetitively switched from one to another every time a sheet feed operation is performed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
237 words
A device installed in an image recording apparatus for feeding a rolled recording medium, comprising: a plurality of recording medium feeding means each comprising pulling means for pulling the leading edge of a rolled recording medium onto a predetermined transport path by holding a part of said recording medium, driving means disposed on said transport path for driving said pulling means, and cutting means for cutting said recording medium along an axis which is substantially perpendicular to an intended direction of recording medium feed; control means for controlling said recording medium feeding means such that said recording medium feeding means for pulling out the recording medium are switched from one to another every time an operation for feeding the recording medium occurs; and sensing means for sensing a kind of the recording medium which is loaded in associated one of said recording medium feeding means, said control means being constructed such that any of said recording medium feeding means which are loaded with the recording medium of a kind specified beforehand are identified on the basis of outputs of said sensing means, said recording medium feeding means loaded with the recording medium of said particular kind are switched from one to another every time an operation for feeding the recording medium occurs, and the switching is inhibited when the recording medium of said particular kind is not accommodated in a plurality of said recording medium feeding means.

Claim 3
Dependent Claim
28 words
A device as claimed in claim 1, wherein said control means is further constructed to inhibit the switching when any of said recording medium feeding means is specified.
