1. A sheet manufacturing apparatus, comprising:
a raw material supplying section that supplies a raw material sheet that contains fibers;
a first coarse crushing section that includes a first coarse crushing blade configured to rotate, and coarsely crushes the raw material sheet supplied from the raw material supplying section;
a defibrating section that defibrates coarse crushed pieces produced by the first coarse crushing section;
a deposition section on which a defibrated material produced by the defibrating section is deposited;
a heating and pressing section that applies heat and pressure to a deposited material produced on the deposition section for forming into a sheet;
a cutting section that cuts the sheet;
an ejection section that ejects the cut sheet;
a casing including a lower part and an upper part overlapping each other when viewed in the vertical direction, the first coarse crushing section and the defibrating section being arranged in the lower part, the deposition section, the heating and pressing section and the cutting section being arranged in the upper part, wherein
when an x axis and a y axis which are orthogonal to each other and each of which is orthogonal to a vertical direction are set, the raw material supplying section and the ejection section are provided on one side in a direction of the x axis,
a rotation axis of the first coarse crushing blade is along the y axis, and
the raw material supplying section is disposed below the ejection section in the vertical direction, and the first coarse crushing section is disposed below the cutting section in the vertical direction.
