ELECTRONIC APPARATUS

PROBLEM TO BE SOLVED: To reduce signal lines in an apparatus, especially signal lines on a backboard to which a plurality of substrates are connected.SOLUTION: An electronic apparatus includes: a timing controller 111 that, which is connected to a plurality of slave substrates 120 included in each of a plurality of groups with first bus wiring 150, in which the slave substrates 120 are divided into the plurality of groups, transmits a first timing signal to the substrates, and, which is connected to the slave substrates 120 included in each of the plurality of groups with second bus wiring 151, transmits a second timing signal indicating a different timing from the first timing signal to the slave substrates; and a monitoring unit 112 that, which is connected to the slave substrate 120 selected one by one from each of the plurality of groups with third bus wiring 152, monitors a monitoring data signal transmitted to the third bus wiring 152. The slave substrate 120 places first data according to the first timing signal and second data according to the second timing signal on the monitoring data signal.SELECTED DRAWING: Figure 3 【課題】装置内の信号線、特に複数基板が接続されるバックボードにおける信号線を少なくすること。【解決手段】複数のスレーブ基板１２０を複数のグループに分けて、複数のグループの各々に含まれるスレーブ基板１２０に第１のバス配線１５０で接続され、第１のタイミング信号を送信するとともに、複数のグループの各々に含まれるスレーブ基板１２０に第２のバス配線１５１で接続され、第１のタイミング信号とは異なるタイミングを示す第２のタイミング信号を送信するタイミング制御部１１１と、複数のグループの各々から１つずつ選択されたスレーブ基板１２０に、第３のバス配線１５２で接続され、第３のバス配線１５２に送信される監視データ信号を監視する監視部１１２と、を備える。スレーブ基板１２０は、第１のタイミング信号に従って第１のデータを、第２のタイミング信号に従って第２のデータを監視データ信号に載せる。【選択図】図３
