Abstract
A prediction apparatus includes: an acquisition unit that acquires an operation amount and a non-operation amount of a transporting unit that transports a medium; and a prediction unit that predicts a timing at which a transporting capability value changing with degradation of the transporting unit arrives at a threshold value using the operation amount and the non-operation amount of the transporting unit acquired by the acquisition unit based on (i) a relational expression between the operation amount of the transporting unit and the transporting capability value of the transporting unit and (ii) a relational expression between the non-operation amount of the transporting unit and the transporting capability value of the transporting unit.
Claims20
A prediction apparatus comprising:
- an acquisition unit that acquires, from a transporting unit, an operation time during which the transporting unit is driving and a non-operation time during which the transporting unit is not driving, the transporting unit transporting a sheet-shaped medium and the transporting unit being roll-shaped or belt-shaped;
- and
- a prediction unit that predicts a change of a transporting time, in the future, of the sheet-shaped medium in the transport unit, and predicts a life end of the transporting unit using a change of the transporting time, the life end being determined based on when the transporting time will be equal to or larger than a predetermined value based on both (i) a relational expression between the operation time and the transporting time and (ii) a relational expression between the non-driving time and the transporting time, the transporting time being a time in which the medium transported by the transporting unit passes through a preset interval.
A prediction system comprising:
- a monitor target apparatus;
- and
- a prediction apparatus connected to the monitor target apparatus through a network, wherein
- the monitor target apparatus comprises a transporting unit that transports a medium, and
- the prediction apparatus comprises:
- an acquisition unit that acquires an operation time during which the transporting unit is driving and a non-operation time during which the transporting unit is not driving, the transporting unit transporting a sheet-shaped medium and the transporting unit being roll-shaped or belt-shaped, the prediction apparatus acquiring the operation time and the non-operation times from the monitor target apparatus through the network;
- and
- a prediction unit that predicts a change of a transporting time, in the future, of the sheet-shaped medium in the transport unit, and predicts a life end of the transporting unit using a change of the transporting time, the life end being determined based on when a transporting time will be equal to or larger than a predetermined value based on both (i) a relational expression between the operation time and the transporting time and (ii) a relational expression between the non-operation time and the transporting time, the transporting time being a time in which the medium transported by the transporting unit passes through a preset interval.

An image forming apparatus comprising:
- an image forming unit that forms an image on a medium;
- a transporting unit that transports a medium on which an image is to be formed;
- an acquisition unit that acquires, from a transporting unit, an operation time during which the transporting unit is driving and a non-operation time during which the transporting unit is not driving, the transporting unit transporting a sheet-shaped medium and the transporting unit being roll-shaped or belt-shaped;
- and
- a prediction unit that predicts a change of a transporting time, in the future, of the sheet-shaped medium in the transport unit, and predicts a life end of the transporting unit using a change of the transporting time, the life end being determined based on when a transporting time will be equal to or larger than a predetermined value based on both (i) a relational expression between the operation time and the transporting time and (ii) a relational expression between the non-operation time and the transporting time, the transporting time being a time in which the medium transported by the transporting unit passes through a preset interval.

A medium transporter comprising:
- a transporting unit that transports a medium on which an image is to be formed;
- an acquisition unit that acquires, from a transporting unit, an operation time that the transporting unit is driving and a non-operation time that the transporting unit is not driving, the transporting unit transporting a sheet-shaped medium and the transporting unit being roll-shaped or belt-shaped;
- and
- a prediction unit that predicts a change of a transporting time, in the future, of the sheet-shaped medium in the transport unit, and predicts a life end of the transporting unit using a change of the transporting time, the life end being determined based on when a transporting time will be equal to or larger than a predetermined value based on both (i) a relational expression between the operation time and the transporting time and (ii) a relational expression between the non-operation time and the transporting time, the transporting time being a time in which the medium transported by the transporting unit passes through a preset interval.
1 more element
A non-transitory computer readable medium storing a computer readable program executable by a computer for causing a computer to execute a process for predicting a timing, the process comprising:
- acquiring, from a transporting unit, an operation time during which the transporting unit is driving and a non-operation time that the transporting unit is not driving, the transporting unit transporting a sheet-shaped medium and the transporting unit being roll-shaped or belt-shaped;
- and
- predicting a change of a transporting time, in the future, of the sheet-shaped medium in the transport unit, and predicts a life end of the transporting unit using a change of the transporting time, the life end being determined based on when a transporting time will be equal to or larger than a predetermined value based on both (i) a relational expression between the operation time and the transporting time and (ii) a relational expression between the non-operation time and the transporting time, the transporting time being a time in which the medium transported by the transporting unit passes through a preset interval.
