To easily adjust a paper pressing plate, in a paper presser guiding the front end of a sheet sequentially sent out of a sheet supply device and restricting the floating of the sheet.

In this paper presser, one end of a support member 14 is installed to a stationary member 11a provided such that a position of the stationary member 11a is fixed relatively to a sheet travel face 2a. The support member 14 supports the paper pressing plate 6 disposed near and nearly parallel to the sheet travel face 2a in a position apart from the installation part. The stationary member 11a and the support member 14 are connected by an adjustment screw 18 in a position apart from the installation part, and are contacted or separated according to a rotation amount of the adjustment screw 18.
