Abstract
A sheet material thickness detection device includes a guide member, a non-rotating pressing member, a sensor, and a calculator. The guide member guides one side of a sheet material being conveyed. The pressing member presses the sheet material against the guide member in a manner displaceable in accordance with the thickness of the sheet material. The sensor is configured to magnetically or electrically detect a displaced amount of the pressing member that is displaced in accordance with the thickness of the sheet material. The calculator is configured to calculate the thickness of the sheet material based on an output signal of the sensor.
