    • An electronic apparatus includes a connection-state detection circuit. The circuit includes a first circuit board; a plurality of second circuit boards that each exchange a signal with the first circuit board; a plurality of connectors that connect the first circuit board and each of the second circuit boards, respectively; a transmitting unit that transmits a connection-state detection signal from the first circuit board to each of the second circuit boards via the connectors; a control unit that causes the second circuit boards to return response signals to the first circuit board in response to the received connection-state detection signal via the connectors at different times that are shifted from each other and are respectively allocated to the second circuit boards; and a detecting unit that detects whether the response signal returned from each of the second circuit boards is received to detect a connection state of each of the connectors.
    • 电子设备包括连接状态检测电路。 该电路包括第一电路板; 多个第二电路板,其与第一电路板交换信号; 多个连接器,分别连接第一电路板和每个第二电路板; 发送单元,其经由所述连接器将来自所述第一电路板的连接状态检测信号发送到每个所述第二电路板; 控制单元,其使得所述第二电路板响应于经由所述连接器的接收到的连接状态检测信号在彼此偏移的不同时间响应于所述第一电路板而返回响应信号,并且分别被分配给所述第二电路板; 以及检测单元,其检测从每个第二电路板返回的响应信号是否被接收以检测每个连接器的连接状态。
