Abstract
A switchback unit has a switchback roller which receives a paper sheet conveyed in a first direction into a nip for forward rotation and backwardly rotates the paper sheet after stopping the paper sheet to feed the paper sheet to a second conveyance path. When the conveyance of the paper sheet stopped on the way to the switchback section is resumed, control is performed so that the switchback roller is forwardly rotated until a sensor detects the tip of the paper sheet, and then the switchback roller is stopped and backwardly rotated.
Claims17
An apparatus for processing paper sheets, comprising:
- a switchback section which receives and stops a paper sheet fed in a first direction and feeds the paper sheet in a second direction opposite to the first direction;
- a first conveyance path through which the paper sheet is fed in the first direction into the switchback section;
- a second conveyance path through which the paper sheet is fed in the second direction from the switchback section;
- a detection section which detects that a rear end of the paper sheet moving in the first direction has reached a position where the rear end can be oriented to the second conveyance path;
- a control section which causes the switchback section to convey the paper sheet in the first direction until the detection section detects that the rear end of the paper sheet has reached the position and causes the switchback section to start conveying the paper sheet in the second direction when the detection section detects that the rear end of the paper sheet has reached the position, in order to convey the paper sheet again after having been stopped before reaching the switchback section.
An apparatus for processing paper sheets, comprising:
- a switchback roller which has a nip and rotates in a first direction to hold a paper sheet in the nip and then to convey into a switchback section, and rotates in a second direction opposite to the first direction to convey the paper sheet in the second direction, while holding the paper sheet in the nip;
- a first conveyance path through which the paper sheet is conveyed in the first direction into the nip of the switchback roller;
- a second conveyance path through which the paper sheet is conveyed in the second direction from the nip of the switchback roller;
- a sensor which detects that a rear end of the paper sheet moving in the first direction into the switchback section has reached a position where the rear end can be oriented to the second conveyance path;
- and
- a control section which causes the switchback roller to rotate in the first direction when the sensor does not detects that the rear end of the paper sheet has reached the position and causes the switchback roller to start rotating in the second direction when the detection section detects that the rear end of the paper sheet has reached the position, in order to convey the paper sheet again after having been stopped before reaching the switchback section.
A method of processing paper sheets, comprising:
- feeding a paper sheet in first direction through a first conveyance path into a switchback section, stopping the paper sheet temporarily, and feeding the paper sheet from the switchback section through a second conveyance path in a second direction opposite to the first direction,
- controlling the switchback section so that the paper sheet is fed in the first direction into the switchback section until the rear end of the paper sheet reaches a position where the rear end can be oriented to the second conveyance path, in order to convey the paper sheet again after having been stopped before reaching the switchback section;
- and
- controlling the switchback section so that the paper sheet is fed in the second direction after the rear end of the paper sheet reaches the position.
