The radishes harvested from the farm contain ones that are short-length or with a forked root. They are called as irregular radishes. The irregular radishes loaded into containers must be eliminated in the radish sizing place after harvest. The radish sizing costs momey and loses time. Therefore we have developed the device eliminating irregular radishes before they would be loaded into the container on the harvester. This eliminating device utilizes photoelectronic sensors and distance measuring sensors. Those sensors detect irregular radishes and the radishes are eliminated in the field before loaded into the container by this device.

This study is on automatic control of the Japanese white radish harvester used in the KAMIKAWA area in HOKKAIDO. This harvester consists of two devices for pulling radish and for loading a container with many radish. These devices are handled by some operators.At present farmers need to reduce operators for saving the cost of the radish harvest.This paper will propose the way to control these devices automatically. By this way the radish harvester can be operated by one or two operators , and farmers can cut back the cost.

"We reported previously that a laser range scanner fitted under the front of a conveyer can successfully search for optimal spaces to load radishes into the container of harvesters, and that an automatic controller can move effectively the conveyor and the container to the optimum spots by receiving signals from the scanner. However, the fitting of the scanner under the front of the conveyer may damage radishes when dropping from the conveyer to the container through a relatively long distance, due to the space for the scanner. In this paper we report the fabrication of a new system in which the scanner is set inside the conveyer to make the radish dropping distance shorter. The new system worked well without the damage of radishes."
