Abstract

PURPOSE:To prohibit press operation in the even of trouble in both-hand operating buttons and achieve safety by suitably series-connecting the respective contacts of the relays for the respective (a) contacts and (b) contacts of the right and left side buttons of said buttons and incorporating these in a press operating circuit and restart preventing circuit. CONSTITUTION:If the (a) contacts of the buttons are ON even if the buttons are not pushed, relays CR1A and CR1B are ON and a restart preventing circuit 3 is held OFF. Hence, in a press operating circuit, CRN is OFF and therefore a press operating relay CRC will not go ON. When the (b) contacts of the buttons are OFF even if they are not pushed, and for example, when the (b) contact of the right side button is OFF, the CR4 in the circuit 3 is OFF and therefore the CRN is OFF and this prohibits the press operation owing to OFF of CRC. When the (b) contacts of the buttons fail to go OFF even when they are pushed, the relay CR3 or CR4 is held OFF and the press operating circuit 1 is OFF and since the relay CRC is held OFF, the press operation cannot be done.
