A conveyance device includes a motor, a conveyance unit, a movement detection signal output unit, a storage unit, a time measurement unit, a first updating unit, a standby time setting unit, a second updating unit, a manipulated variable determination unit, and a motor driving unit. The standby time setting unit sets a value larger than a parameter value TX stored in the storage unit as a standby time TW. The second updating unit updates the parameter value TX stored in the storage unit to the standby time TW each time the elapsed time measured by the time measurement unit reaches the standby time TW.
