Abstract
A paper conveying device, used in a paper processing device to perform predetermined processing on paper, includes a conveying portion, a holding portion, a detection portion, and a control portion. The conveying portion conveys, in a conveying direction, the paper to a processing portion of the paper processing device. The holding portion is disposed downstream of the processing portion in the conveying direction and holds the paper processed by the paper processing device. The detection portion detects a change of an orientation of the paper held by the holding portion. The control portion releases the paper held by the holding portion in a case where an amount of the detected orientation change reaches a predetermined amount.
Claims32
A paper conveying device comprising:
- a conveying portion configured to convey, in a conveying direction, a paper to a processing portion of a paper processing device to perform predetermined processing on the paper;
- a holding portion disposed downstream of the processing portion in the conveying direction and configured to hold the paper processed by the paper processing device;
- a detection portion, including a sensor capable of detecting a distance between the sensor and a detection target, is configured to continuously detect a distance to the paper held by the holding portion in a predetermined period;
- and
- a control portion configured to release the paper held by the holding portion in a case where the distance continuously detected in a longer period is kept at a distance reaching a first threshold value.
A method for a paper conveying device having a conveying portion, a holding portion disposed downstream of a processing portion of a paper processing device in a conveying direction, and a detection portion including a sensor capable of detecting a distance between the sensor and a detection target, the method comprising:
- conveying, by the conveying portion in the conveying direction, a paper to the processing portion of a paper processing device to perform predetermined processing on the paper;
- holding, by the holding portion, the paper processed by the paper processing device;
- detecting continuously, by the detection portion, a distance to the paper held by the holding portion in a predetermined period;
- and
- releasing the paper held by the holding portion in a case where the distance continuously detected in a longer period is kept at a distance reaching a first threshold value.
A non-transitory computer-readable storage medium storing a program to cause a computer to perform a method for a paper conveying device having a conveying portion, a holding portion disposed downstream of a processing portion of a paper processing device in a conveying direction, and a detection portion including a sensor capable of detecting a distance between the sensor and a detection target, the method comprising:
- conveying, by the conveying portion in the conveying direction, a paper to the processing portion of a paper processing device to perform predetermined processing on the paper;
- holding, by the holding portion, the paper processed by the paper processing device;
- detecting continuously, by the detection portion, a distance to the paper held by the holding portion in a predetermined period;
- and
- releasing the paper held by the holding portion in a case where the distance continuously detected in a longer period is kept at a distance reaching a first threshold value.
A paper conveying device comprising:
- a conveying portion configured to convey, in a conveying direction, a paper to a processing portion of a paper processing device to perform predetermined processing on the paper;
- a holding portion disposed downstream of the processing portion in the conveying direction and configured to hold the paper processed by the paper processing device;
- a detection portion, including a sensor capable of detecting a distance between the sensor and a detection target, is configured to continuously detect a distance to the paper held by the holding portion in a predetermined period;
- and
- a control portion configured to release the paper held by the holding portion,
- wherein a first threshold value is set based on a detected distance detected by the sensor in a state where the paper processed by the processing portion is held by the holding portion and further set based on a detected distance detected by the sensor in absence of the paper being in a detection range of the sensor, and
- wherein the control portion releases the paper processed by the processing portion and held by the holding portion in a case where the distance continuously detected by the detection portion is longer than the first threshold value.
A method for a paper conveying device having a conveying portion, a holding portion disposed downstream of a processing portion of a paper processing device in a conveying direction, and a detection portion including a sensor capable of detecting a distance between the sensor and a detection target, the method comprising:
- conveying, by the conveying portion in the conveying direction, a paper to the processing portion of a paper processing device to perform predetermined processing on the paper;
- holding, by the holding portion, the paper processed by the paper processing device;
- detecting continuously, by the detection portion, a distance to the paper held by the holding portion in a predetermined period, wherein a first threshold value is set based on a detected distance detected by the sensor in a state where the paper processed by the processing portion is held by the holding portion and further set based on a detected distance detected by the sensor in absence of the paper being in a detection range of the sensor;
- and
- releasing the paper processed by the processing portion and held by the holding portion in a case where the distance continuously detected by the detection portion is longer than the first threshold value.
