A printer includes a first housing part, a second housing part, a printing part that prints on the first paper sheet and the second paper sheet, a conveying part that includes a holding part that is configured to hold the overlapping first paper sheet and the second paper sheet respectively pulled out from a first paper roll and a second paper roll, and conveys the first paper sheet out of the first paper sheet and the second paper sheet held by the holding part to the printing part, a first paper sheet sensor that detects the presence of the first paper sheet, and a controlling part that makes the conveying part convey the second paper sheet held by the holding part to the printing part when the first paper sheet sensor detects that there is no first paper sheet to be conveyed to the printing part.

A printing apparatus includes a stacking portion on which a print medium printed by a printing unit configured to perform printing is stacked, a discharge unit configured to discharge the print medium printed by the printing unit to the stacking portion, a passage forming portion arranged facing the stacking portion and configured to form a discharge passage of the print medium together with the stacking portion, and an outlet port located at a downstream end of the stacking portion and a downstream end of the passage forming portion in a conveying direction of the print medium. The passage forming portion includes an opening/closing portion which is displaceable between a closed position for forming the discharge passage and an open position for opening access to the stacking portion.

The present disclosure provides a paper stop structure, a paper feed unit, and an image forming apparatus. The paper stop structure includes a movement stopper and a paper stopper both swingably configured in a paper feed path, and a separation structure to separate the movement stopper and the paper stopper. In paper stopping state, the paper stopper is pushed by an external force to swing until contacting the movement stopper, and blocks paper sheets from entering the paper feed path. In non-paper stopping state, the paper stopper is pushed by an external force to swing and separates from the movement stopper. Accordingly, various functions of paper feeding, paper stopping, and paper detecting may be achieved, and large capacity paper feeding can also be achieved to improve product operating efficiency and to effectively prevent paper mis-feed and paper jam during the image forming apparatus operation.

The sheet feeding apparatus of the invention includes a sheet stacking portion, a rotating body, a contact member, a conveyance guide, a driving source, a shutter member and a torque limiter. The torque limiter is disposed between the rotating body and the driving source, transmits a driving force of the driving source to the rotating body in a state that a load in the sheet feeding direction of less than a predetermined torque is applied to the rotating body, and not transmit the driving force of the driving source to the rotating body in a state that the load in the sheet feeding direction of more than the predetermined torque is applied to the rotating body.

A printer includes a first housing part, a second housing part, a printing part that prints on the first paper sheet and the second paper sheet, a conveying part that includes a holding part that is configured to hold the overlapping first paper sheet and the second paper sheet respectively pulled out from a first paper roll and a second paper roll, and conveys the first paper sheet out of the first paper sheet and the second paper sheet held by the holding part to the printing part, a first paper sheet sensor that detects the presence of the first paper sheet, and a controlling part that makes the conveying part convey the second paper sheet held by the holding part to the printing part when the first paper sheet sensor detects that there is no first paper sheet to be conveyed to the printing part.

A component supplying apparatus comprises a tape guide surface facing a lower surface of the carrier tape, a preceding tape contact part climbing onto a upper surface of the preceding carrier tape, and a subsequent tape blocking part configured to wait on the upstream side of the preceding tape contact part in a tape feeding direction while keeping a distance from the tape guide surface so as to enable the carrier tape to pass between the subsequent tape blocking part and the tape guide surface, and to move downwardly toward the preceding carrier tape when the preceding tape contact part is climbed onto the preceding carrier tape. The subsequent tape blocking part keeps the subsequent carrier tape waiting by contacting a front end of the subsequent carrier tape stacked on the preceding carrier tape onto which the preceding tape contact part climbs.

A feeding device is disclosed, which comprises a paper passage, a sheet-separating roller, a friction institution, and a stopper. The sheet-separating roller is disposed in the paper passage. The friction institution is disposed in the paper passage opposite to the sheet-separating roller. The stopper is disposed in the upstream side of the sheet-separating roller. The stopper includes an axle, a short arm, and a long arm. The short arm connects to the axle, and the axle acts as a fulcrum. The long arm and the short arm disposed to the axle coaxially. A threshold of the force for pushing the short arm is larger than a threshold of the force for pushing the long arm.

This disclosure is directed to a printing equipment and a continuous feeding and cutting device thereof. The continuous feeding and cutting device is detachably assembled on an inlet of the printer and applied to a continuous form paper. The continuous feeding and cutting device has a paper picking module for transferring the continuous form paper to the inlet, a buffering module, a cutting mechanism and a processing unit. The buffering module is arranged between the inlet and the paper picking module for guiding the continuous form paper to perform a curved manner to the inlet. The cutting mechanism is arranged between the paper picking module and the curved guide for cutting the continuous form paper. The processing unit is electrically connected to the cutting mechanism for controlling the cutting mechanism to cut the continuous form paper.

A stacker includes a placement part that stacks thereon sheets discharged from a discharge port by a conveyor that conveys the sheets; a side guide that regulates edges of the sheets in a width direction intersecting a discharge direction of the sheets; a guide driver that moves the side guide along the width direction; and a controller configured to control the guide driver to position the side guide at a position where the sheet discharged from the discharge port is supported from below by the side guide.
