1. A poultry leg meat deboning device configured to perform a separation of a meat part from a femur with respect to a poultry leg meat to which a peeling off of the meat part has been performed until a side of a knee joint of the femur in a bone-in poultry leg meat which has been cut from a femur of a poultry carcass, the poultry leg meat deboning device comprising:
an ankle holding part configured to hold an ankle of the poultry leg meat;
a leg meat measuring part configured to measure between at least a part of the poultry leg meat closer to the ankle holding part than the knee joint and a cutting part of the poultry leg meat on a side of a hip joint of the poultry leg meat, at a side closer to the femur than the ankle holding part in a state before the peeling off of the meat part of the poultry leg meat has been performed;
a separator configured to sandwich the femur from a direction crossing an extension direction of the femur in between the side of the knee joint of the femur and the meat part;
a moving part configured to move at least one of the ankle holding part and the separator so that one of the ankle holding part and the separator separates with respect to the other one of the ankle holding part and the separator while maintaining a state in which the separator is sandwiching and configured to relatively move the separator until an end portion of the femur on the side of the hip joint along the femur;
a controller configured to determine movement amount of the separator with respect to the femur by the moving part on the basis of a measurement result by the leg meat measuring part; and
a cutter configured to cut off the meat part from the femur at the end portion of the femur.
