Abstract

A sheet manufacturing apparatus includes a raw material detection unit that detects a raw material amount stacked on a stacking unit, a calculation unit that calculates a first amount of the sheet able to be manufactured in the sheet manufacturing apparatus based on a detection result of the raw material detection unit, and an output unit that outputs the sheet amount calculated by the calculation unit.

First claim

What is claimed is:

1. A sheet manufacturing apparatus for manufacturing a sheet by using a raw material containing fibers supplied from a stacking unit on which the raw material is stacked, the apparatus comprising:
a raw material detection unit configured to detect a raw material amount stacked on the stacking unit;
a calculation unit configured to calculate a first amount of the sheet able to be manufactured in the sheet manufacturing apparatus based on a detection result of the raw material detection unit; and
an output unit configured to output the sheet amount calculated by the calculation unit.

2. A sheet manufacturing apparatus for manufacturing a sheet by using a raw material containing fibers supplied by a supply unit supplying the raw material, the apparatus comprising:
an adding unit configured to add additives to the raw material supplied by the supply unit;
a remaining amount detection unit configured to detect an additive remaining amount;
a calculation unit configured to calculate the sheet amount able to be manufactured in the sheet manufacturing apparatus based on a detection result of the remaining amount detection unit; and
an output unit configured to output the sheet amount calculated by the calculation unit.

3. A sheet manufacturing apparatus for manufacturing a sheet by using a raw material containing fibers supplied by a supply unit supplying the raw material, the apparatus comprising:
a storage unit configured to store at least a part of the raw material supplied by the supply unit which is not used in manufacturing of the sheet;
a storage amount detection unit configured to detect an amount able to be stored in the storage unit;
a calculation unit configured to calculate the sheet amount able to be manufactured in the sheet manufacturing apparatus based on a detection result of the storage amount detection unit; and
an output unit configured to output the sheet amount calculated by the calculation unit.

4. The sheet manufacturing apparatus according to claim 1 , further comprising:
an adding unit configured to add the additives to the raw material supplied from the stacking unit; and
a remaining amount detection unit configured to detect an additive remaining amount,
wherein the calculation unit is configured to calculate a second amount of the sheet able to be manufactured in the sheet manufacturing apparatus based on a detection result of the remaining amount detection unit, and
wherein the output unit is configured to output a smaller one of the first amount and the second amount.

5. The sheet manufacturing apparatus according to claim 4 , further comprising:
a storage unit configured to store at least a part of the raw material supplied from the stacking unit which is not used in manufacturing of the sheet; and
a storage amount detection unit configured to detect an amount able to be stored in the storage unit,
wherein the calculation unit is configured to calculate a third amount of the sheet able to be manufactured in the sheet manufacturing apparatus based on a detection result of the storage amount detection unit, and
wherein the output unit is configured to output the smallest one of the first amount, the second amount, and the third amount.
