PURPOSE:To form a data fetching device prevented from a data fetching error by adding a delay circuit delaying an output signal from an operation switch part to the data fetching device. CONSTITUTION:The titled device is provided with a main controlling means 3 controlling apparatus and the operation switch part 12 outputting operation indicating data for the apparatus. In addition, a rectangular wave outputting circuit 10 outputting a rectangular wave signal from an output terminal 0 of the main controlling means 3 and a phase inverter 11 inverting the phase of an input signal to the rectangular wave outputting circuit 10 are also connected to the titled device. The operation switch part 12 scans an output signal from the rectangular wave outputting circuit 10 and an output signal of the phase inverter 11 and the delay circuit 13 delays the scanned output signal of the operation switch part 12 and inputting the delayed signal with time sharing. Thus, the data fetching device prevented from an data fetching error can be formed. |
