Abstract
In accordance with an embodiment, a sheet processing apparatus, containing a controller that acquires a predetermined data associated with a physical quantity of one of a driving motor or a driven member driven by the motor based on a predetermined signal, compare the predetermined data with a threshold value, and determine whether to transmit a request for increasing a discharge interval of a sheet based on the comparative result.
Claims10
A sheet processing apparatus, comprising:
- a sheet processing section configured to carry out a post-processing on a sheet discharged from an image forming apparatus;
- a motor configured to drive a driven member of the sheet processing section;
- an encoder configured to output a predetermined signal based on a rotation of an axis to which rotational force of the motor is transmitted;
- a memory configured to store a threshold value;
- and a controller configured to
- acquire a predetermined data associated with a physical quantity of one of the motor or the driven member driven by the motor based on the predetermined signal,
- compare the predetermined data with the threshold value, and
- determine whether to transmit a request for increasing a discharge interval of the sheet discharged from the image forming apparatus to the image forming apparatus based on a comparative result of a comparison of the predetermined data with the threshold value, wherein the encoder is configured to convert a rotation of the axis of the motor to which rotational force of the motor is transmitted to a pulse, and
- wherein
- the controller is configured to
- acquire a counted number during a predetermined time interval by counting pulses converted by the encoder, and
- transmit the request to the image forming apparatus if the counted number during the predetermined time interval is smaller than the threshold value.
A control method of a sheet processing apparatus which comprises a sheet processing section configured to carry out a sheet processing on a sheet discharged from an image forming apparatus, a motor configured to drive a driven member of the sheet processing section and a memory configured to store a threshold value, comprising
- receiving a predetermined signal output by an encoder based on a rotation of an axis to which rotational force of the motor is transmitted;
- acquiring a predetermined data associated with a physical quantity of one of the motor or the driven member driven by the motor based on the predetermined signal;
- comparing the predetermined data with the threshold value;
- and
- determining whether to transmit a request for increasing a discharge interval of the sheet discharged from the image forming apparatus to the image forming apparatus based on a comparative result of a comparison of the predetermined data with the threshold value, wherein the predetermined signal is a pulse converted, by the encoder, from a rotation of the axis of the motor to which rotational force of the motor is transmitted, and
- wherein
- the predetermined data is a moving distance of the driven member, and
- the method further comprising:
- acquiring the moving distance of the driven member from a counted number obtained by counting pulses;
- and
- transmitting the request to the image forming apparatus if the moving distance is smaller than the threshold value.

- receiving a predetermined signal output by an encoder based on a rotation of an axis to which rotational force of the motor is transmitted;
- acquiring a predetermined data associated with a physical quantity of one of the motor or the driven member driven by the motor based on the predetermined signal;
- comparing the predetermined data with the threshold value;
- determining whether to transmit a request for increasing a discharge interval of the sheet discharged from the image forming apparatus to the image forming apparatus based on a comparative result of a comparison of the predetermined data with the threshold value, wherein the predetermined signal is a pulse converted, by the encoder, from a rotation of the axis of the motor to which rotational force of the motor is transmitted;
- acquiring a counted number of the pulse during a predetermined time interval based on pulses;
- and
- transmitting the request to the image forming apparatus if the counted number during the predetermined time interval is smaller than the threshold value.
