Abstract:
1. A sheet conveying apparatus comprising: a conveying unit that conveys a sheet by holding in a nip portion, the nip portion formed by a pair of rollers as a rotating unit such that one of the pair of rollers contacts and pressurizes the other roller; a pressure lever of which a fixed edge is oscillatably supported by an immovable portion, the pressure lever including an oscillating edge, the oscillating edge of the pressure lever being capable of contacting a supporting shaft of a pressure roller; an oscillating lever of which a fixed edge is oscillatably supported by the pressure lever in the oscillating edge side, the oscillating lever including a plurality of oscillating edges around the fixed edge of the oscillating lever; and an elastic unit that is latched between the fixed edge of the oscillating lever and the immovable portion, and biases the oscillating lever towards the one of the pair of rollers, wherein a position of the fixed edge of the oscillating lever, from among positions at which an end of the elastic unit is latched on, is capable of being changed in a state of being deviated from a position before oscillating based on an oscillating position of the oscillating lever separately from an oscillation of the fixed edge of the oscillating lever.
