Abstract

PURPOSE:To enhance the controllability, by providing a flicker display circuit that displays a misoperation in case when an operation switch having no display indicating the capability of operation is mistakenly operated. CONSTITUTION:When a hopper is driven with a operation switch 2S, the upper G lamp of a selection switch 4SL(b) of a downstream damper glows to indicate that the switch 4SL(b) can be operated. Then the switch 4SL(b) is pushed to turn off the G lamp and turn on the lower R lamp, and thus a correct operation is displayed. Thereafter, the G lamps of both selection switches 7SL(a) and 7SL(b) of DA13 that select directions are lit up to indicate the capability of operation. If a switch 4SL(a) is operated, a flicker circuit which is not shown in the diagram works to display a misoperation.
