Description

Material storage device, control method for material storage device, and sheet manufacturing apparatus Technical Field The present invention relates to a material storage device, a control method for the material storage device, and a sheet manufacturing apparatus. Background Conventionally, as shown in patent document 1, a paper feeding device for feeding shredded paper to a target portion is disclosed. The paper feeding device includes a hollow transfer passage member having a transfer space therein, a paper feeding portion provided at an upstream side of the transfer passage member to feed paper into the transfer passage member, a discharge portion provided at a downstream side of the transfer passage member to discharge paper from the transfer passage member to a target portion, and a blower that blows air into the transfer passage member to generate an air flow for causing the paper fed from the paper feeding portion into the transfer passage member to flow toward the discharge portion. In such a paper feeding device, a certain amount of paper is fed from the outside toward the paper feeding portion. In this case, there is a possibility that the paper and the paper dust fly up due to convection generated at the time of paper input or impact on the paper stored in the paper input portion, and the like, and the paper and the like are ejected from the paper input portion to the outside. Patent document 1 Japanese patent application laid-open No. 2011-149106 Disclosure of Invention The material storage device is provided with a material storage unit having a material storage unit for storing paper sheets and having an inlet through which the paper sheets can be introduced into the interior, and a cover unit capable of opening and closing the inlet, a humidifying unit having a first blower for supplying humidified air into the material storage unit, and an air circulation unit having a second blower for sucking air in the material storage unit, wherein the interior of the material storage unit is negative pressure when the cover unit is in an open state. The sheet manufacturing apparatus includes the above-described material storage apparatus. In a method for controlling a material storage device including a material storage unit having a material storage unit that stores a sheet of paper and having an inlet through which the sheet of paper can be introduced into the material storage unit, and a cover unit that opens and closes the inlet, a humidifying unit having a first blower that supplies humidified air into the material storage unit, and an air circulation unit having a second blower that sucks air in the material storage unit, the inside of the material storage unit is brought into a negative pressure when the cover unit is in an open state.
