Claims

[Scope of utility model registration request]

A paper feeder that is movable up and down inside the paper feed tray and that allows the topmost sheet of paper on top of the table to be fed by a feed roller by raising and lowering a paper loading table on which paper is stacked and placed. In the paper feeding device that can be placed at the lowest position, there is provided a paper presence/absence detection means for detecting whether or not paper is placed on the paper placing table, and whether the paper placing table is placed at the lowest position. a table position detection means for detecting whether there is no paper on the paper loading table; A paper feeding device comprising a platform lowering means for lowering the paper loading platform to the lowest position when it is detected that there is no paper loading device.
