ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a process for feeding recording media into a recorder such as a printer, a facsimile, a copying machine and the like, and to a package form of recording media used for the process.
Background Art
As a process for feeding a recording medium such as paper into a recorder such as a printer, a facsimile or a copying machine, there is generally employed a method comprising the steps of loading and piling up recording media in a housing such as a tray, drawing out a recording medium one by one from the housing with use of a feeding device such as a feeding roller pressed against the recording medium, and feeding the recording medium into the recorder.
On the other hand, recording media which have been subjected to various processings have been recently used to realize high quality printing. For example, a recording medium having the surface which is smoothed to add gloss to it has been used. Furthermore, a recording medium having a layer for receiving a coloring material such as an ink composition for the purpose of realizing a high quality printed image. The recording-medium-housing such as a tray or the recording medium feeding system of a recorder is generally designed on the assumption of employing plain paper. When the treated recording medium mentioned above is fed into such a recorder, the glossy surface of the recording medium is sometimes adsorbed on a tray and thus the last recording medium fails of being fed smoothly from the recording-medium-housing.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a process for feeding smoothly the last recording medium in a recording medium feeding system.
Another object of the present invention is to provide a packed product of recording media used for the process according to the present invention.
Thus, the present invention provides a process for feeding a recording medium into a recorder from a housing in which recording media are loaded and piled up, comprising the steps of:
providing the extra sheet between the housing and the piled recording media,
pressing a member against the recording medium in the housing, and
operating the member in such a manner that the recording medium is drawn out from the housing to feed the recording medium to the recorder,
wherein the following equation is satisfied:
&mgr;a≧&mgr;c and &mgr;b>&mgr;c
where &mgr;a represents coefficient of static friction between the member and the surface of the recording medium against which the member is pressed,
&mgr;b represents coefficient of static friction between the extra sheet and the surface of the housing, and
&mgr;c represents coefficient of static friction between the extra sheet and the surface of the recording medium which faces the surface of the housing,
Furthermore, the present invention also provides a packed product of the recording media used for the process according to the present invention comprises the packed product of the recording media which are piled up and the extra sheet.
