1. A composite sheet manufacturing device comprising:
a first roller having a first outer circumferential face, a plurality of recessed areas retracted from the first outer circumferential face, and a first gear on an axis thereof,
a second roller disposed so as to be adjacent to the first roller, rotated in synchronization with the first roller, and having a second outer circumferential face opposed to the first outer circumferential face of the first roller, a plurality of first projections that protrude from the second outer circumferential face so as to be inserted into and extracted from the recessed areas of the first roller in a state in which a clearance is provided between each first projection thereof and each recessed area of the first roller, and a second gear on an axis thereof directly engaging the first gear,
a third roller disposed so as to be adjacent to the first roller, rotated in synchronization with the first roller, and having a third outer circumferential face opposed to the first outer circumferential face of the first roller, and a third gear on an axis thereof directly engaging the first gear,
a fourth roller disposed so as to be adjacent to the first roller, rotated in synchronization with the first roller, and having a fourth outer circumferential face opposed to the first outer circumferential face of the first roller, a plurality of second projections that protrude from the fourth outer circumferential face so as to be inserted into and extracted from the recessed areas of the first roller in a state in which a clearance is provided between each second projection thereof and each recessed area of the first roller, and a fourth gear on an axis thereof directly engaging the first gear, and
a fifth roller disposed so as to be adjacent to the first roller, rotated in synchronization with the first roller, and having a fifth outer circumferential face opposed to the first outer circumferential face, and a fifth gear on an axis thereof directly engaging the first gear,
wherein a first sheet is fed in between the first roller and the second roller, conveyed while being supported by the first outer circumferential face of the first roller and passed through a space between the first roller and the second roller, so that when the first sheet is passed through the space between the first roller and the second roller, the first projections of the second roller push the first sheet into the recessed areas of the first roller, and thereby the first sheet is shaped,
a second sheet is superimposed onto the shaped first sheet and conveyed together with the first sheet and then passed through a space between the first roller and the third roller, so that when the first sheet and the second sheet are passed through the space between the first roller and the third roller, the first roller and the third roller hold the first sheet and the second sheet therebetween, and thereby the first sheet and the second sheet are bonded to each other,
each outer diameter of the first roller, the third roller and the fifth roller has a same size,
each outer diameter of a first tip circle of the first projections that protrude from the second outer circumferential face of the second roller and a second tip circle of the second projections that protrude from the fourth outer circumferential face of the fourth roller has a same size, and
numbers of teeth of each of the first gear, third gear and fifth gear are the same, and
numbers of teeth of each of the second and fourth gears are the same.
