Abstract

PURPOSE:To enhance the channel selection precision with a simple production and a light operation, by cancelling all plays of the link part dependent upon the link mechanism by the depression force of the channel selection material. CONSTITUTION:When button 9 is depressed under the state where control plate 5 is suppressed, channel selection material A advances, and its memory piece 4 agrees with the intersection between a pair of inclined edges 11 and 11' while guided by one of them. At this time, movable plates 10 and 10' receive movable forces in different directions because edges 11 and 11' have opposite directions, and link piece 18 linked to movable plate 10 and link piece 18' linked to movable piece 10' are moved to the arrow (a) direction and the direction opposite to the arrow (a) respectively. Therefore, all plays in the stop part between long hole 12 and stop pin 13 and in pivotally-fixed link parts at both edges of link pieces 18 and 18' are cancelled by the component force of the movable direction of part material A, which is generated at the striking action point between edges 11 and 11', and movable forces of opposite directions of movable plates 10 and 10'. Consequently, a special oppressing material and so on are not required, so that the channel selection precision can be enhanced with a simple production and a light operation.
