Estimating the term…
A sheet detecting apparatus includes: a light emitting unit that emits light emitted toward a detection position; a light receiving unit that is provided to receive the light reflected by a sheet present at the detection position and that outputs an electric signal which corresponds to a received light amount; and an adjustment processing unit that adjusts, within a specified range, a duty ratio of a drive pulse signal used to drive the light emitting unit, so that a detection value of the electric signal output from the light receiving unit is included in a specified standard range; and a decision processing unit that decides the specified range based on a change range which is among a variable range of the duty ratio of the drive pulse signal and in which the detection value of the electric signal changes in response to a change in the duty ratio.
A sheet detecting apparatus comprising:
A signal adjusting method executed by a sheet detecting apparatus including a light emitting unit that emits light emitted toward a detection position, and a light receiving unit that is provided to be capable of receiving the light reflected by a sheet present at the detection position and that outputs an electric signal which corresponds to a received light amount, the signal adjusting method comprising:
