<p><P>PROBLEM TO BE SOLVED: To reduce crosstalk noise in a transmitting apparatus, to the wiring board of which a plurality of electronic circuit boards are connected, and the electronic circuit boards to be connected to the wiring board. <P>SOLUTION: The wiring board of the transmitting apparatus has: a plurality of signal input terminals; wirings extending from the signal input terminals; and a wiring concentration section in which the wirings are arranged and gather. Each electronic circuit board has: a device which outputs signals; an output phase control section which controls timing in which the device outputs signals; and a signal output terminal, which is connected to each of the signal input terminals and outputs the signals from the boards. The electronic circuit board or a control board of the transmitting apparatus determines phase difference information from reference timing so as to be different signal change timing between the adjacent signals in the wiring concentration section, and the output phase control section controls timing of output of the signals based on the phase difference information and the reference timing. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
