Paper feeder, auxiliary roller, paper feeding method using the same, and recording apparatus incorporating the same

A feeder for feeding a recording material, comprising:

• a storage section, in which a plurality of recording materials are stacked;
• a feed roller, for feeding a top one of the recording materials in the storage section by rotating forwardly, the feed roller being rotatable reversely;
• a transport roller, for transporting the fed recording material by rotating forwardly, the transport roller being rotatable reversely;
• an abutment driver, for moving the storage section between an abutment position and a separated position, the abutment position at which the recording materials are abutted onto the feed roller, the separated position being separated from the feed roller;
• a first separator, provided with a first abutment part, the separator being movable between an abutment position and a separated position, the abutment position at which the first abutment part is abutted onto the feed roller to separate the top one of the recording material from a subsequent recording material, the separated position at which the first abutment part is separated from the feed roller;
• and
• a controller for controlling the feed roller, the transport roller, the abutment driver and the first separator such that:
• the abutment driver and the separator are moved to the respective abutment position;
• the feed roller and the transport roller are rotated forwardly until a leading end of the fed recording material, which is transported by the transport roller, is transported therefrom by a first predetermined length which is not less than a feeding path length between a leading end of the recording material stacked in the storage section, and an abutment center point of the first separator and the feed roller;
• the rotations of the feed roller and the transport roller are stopped;
• the abutment driver and the separator are moved to the respective separated positions;
• and
• the transport roller is rotated reversely by a predetermined rotation amount which corresponds to a second predetermined length which is not less than the first predetermined length.

A feeder, comprising:

• a detachable storage section in which a plurality of recording material are stacked;
• a feeder roller, for feeding a top one of the recording materials in the storage section;
• and
• an auxiliary roller being rotatable freely, the auxiliary roller disposed such that a roller face thereof is protruded from a roller face of the feed roller toward the attached storage section, the auxiliary roller disposed such that it is moved by the recording material in accordance with a displacement of the recording material in the stacking direction thereof.

A feeder comprising:

• a storage section in which a plurality of recording materials are stacked;
• a feed roller, for feeding a top one of the recording materials in the storage section;
• a transport roller, for transporting the recording material fed by the feed roller while recording is performed;
• a separator, being movable between an abutment position and a separated position with respect to the feed roller, the separator being moved to the abutment position to separate the top recording material from a subsequent recording material when the feed roller feeds the top recording material toward the transport roller, the separator being moved to the separated position while the recording is performed, wherein a stopper is provided so that the separated position of the separation pad is defined, and
• at least one auxiliary roller, disposed at an upstream side of the separator, the auxiliary roller being abutted onto the fed recording material to guide the top recording material toward the separator, after separating the subsequent recording material from the top recording material.

A feeder, comprising:

• an auxiliary roller;
• a detachable storage section in which a plurality of recording materials are stacked;
• and
• a feed roller, for feeding a top one of the recording materials in the attached storage section;
• wherein the auxiliary roller is rotatable freely;
• wherein the auxiliary roller is disposed such that a roller face thereof is protruded from a roller face of the feed roller toward the attached storage section;
• and
• wherein the auxiliary roller is disposed such that it is moved by the recording material in accordance with a displacement of the recording material in the stacking direction thereof.

• and
• a separator, being movable between an abutment position and a separated position with respect to the feed roller, the separator being moved to the abutment position to separate the top recording material from a subsequent recording material when the feed roller feeds the top recording material toward the transport roller, the separator being moved to the separated position while the recording is performed, wherein a stopper is provided so that the separated position of the separation pad is defined,
• wherein the auxiliary roller is disposed at an upstream side of the separator;
• and
• wherein the auxiliary roller is abutted onto the fed recording material to guide the top recording material toward the separator, after separating the subsequent recording material from the top recording material.
