1. An electronic apparatus comprising:
a drive unit including a drive roller configured to rotate about an axial line, a driving motor connected to the drive roller, and a limited-life component that degrades with rotation of the drive roller;
a control device including a processor, and configured to act as a controller that drives the driving motor so as to rotate the drive roller, when the processor executes a control program;
a sound collecting device that collects sound of the limited-life component generated while the drive roller is rotating, and outputs sound data;
a storage device storing in advance a sound pressure level corresponding to a specific frequency of a limited-life component, with respect to each of different lengths of the remaining service life; and
a display device,
the controller being configured to:
perform frequency analysis of the sound data outputted from the sound collecting device at each of predetermined time points;
acquire the sound pressure level corresponding to the specific frequency of the limited-life component, on a basis of a result of the frequency analysis;
compare between the acquired sound pressure level and the sound pressure level corresponding to each of the different lengths of the remaining service life;
predict the remaining service life of the limited-life component, on a basis of a comparison result; and
cause the display device to display a screen showing the predicted remaining service life,
wherein the electronic apparatus includes a plurality of the drive units respectively located at different positions,
the sound collecting device collects the sound from a predetermined first direction, and a second direction opposite to the first direction, and
the controller is configured to:
perform the frequency analysis of each of first sound data representing the sound from the first direction and second sound data representing the sound from the second direction;
acquire a first sound pressure level corresponding to the specific frequency of the limited-life component with respect to the first sound data, and a second sound pressure level corresponding to the specific frequency of the limited-life component with respect to the second sound data, on a basis of a result of the frequency analysis; and
identify the drive unit that includes the limited-life component, the remaining service life of which has been predicted, out of the plurality of the drive units, on a basis of a difference between the first sound pressure level and the second sound pressure level.
