Facsimile apparatus with two different sized paper supply rolls having timer/counter to choose primary supply roll to prevent curling

U.S. Patent Number: 5268766

Abstract: A facsimile apparatus which includes a control part, first and second rolls of first and second recording sheets of different sizes, a platen roller being driven to transport a recording sheet selectively being fed from either the first roll or the second roll, a thermal recording head being provided in contact with the platen roller for carrying out thermal recording, a first feed roller being driven to transport the first recording sheet from the first roll to the platen roller, and a second feed roller being driven to transport the second recording sheet from the second roll to the platen roller. The facsimile apparatus further includes a sheet size sensing part for sensing a sheet size from a sheet size code included in a prescribed control signal being provided each time transmission data when received from an external facsimile terminal, and a counter part for counting the number of each of first and second sheet size occurrences at the sheet size sensing part, so that a leading edge of either the first recording sheet or the second recording sheet, whichever has a greater number of the sheet size occurrences obtained by the counter part, is preferentially placed on the platen roller.
