断されることのないようにした割り込み管理回路。[Claims for Utility Model Registration] In a device having a plurality of printed boards, the order of interrupts from each printed board is determined by transmitting signals through lines connecting the printed boards in series, A switch is provided between the terminals of each printed board to which the line is connected, which turns off when the printed board is mounted and turns on when the printed board is removed, even if the printed board is removed. An interrupt management circuit that prevents the line from being disconnected.
