Abstract

PURPOSE:To reduce the storage of the unnecessary operation recording of the start and stoppage of charging operation even when the start and stoppage of charging operation are repeated irregularly during the charging operation of grains. CONSTITUTION:When the passage of grains during the charging of grains is detected by an unhulled-rice flow sensor 6 when the charging operation of grains is conducted and a fixed time passes, a residue sensor 7' detecting the presence of grains is changed over and controlled under an ON state under the state, in which grains are detected, even under the state, in which grains are not detected. When the unhulled-rice flow sensor 6 detects grains and the fixed time passes, the residue sensor 7' is changed over and controlled under the ON state under the state, in which grains are detected, thus treating subsequent charging as additional charging, then reducing unnecessary operation recording.
