Abstract: A paper warping detection device includes an input tray, a processor, a first emitting element, a first receiving element and a first analog-to-digital converter. A first critical value is stored in the processor. The first emitting element is electrically connected with the processor. The first receiving element is disposed to the other side of the input tray. The first receiving element and the first emitting element face each other. When the first emitting element is switched on, the first emitting element emits first ultrasonic wave signals towards the first receiving element. The first analog-to-digital converter is electrically connected with the first receiving element and the processor for converting the first ultrasonic wave signals into first digital signals and outputting the first digital signals to the processor. The processor reads the first digital signals and compares the first digital signals with the first critical value.
