Filed: 1987-03-25
Abstract: PURPOSE:To increase the information processing speed by realizing execution of other processing steps even in an execution mode of a series of information processes and in the executing time of a certain processing step. CONSTITUTION:The value showing 3sec is added to the memory time X of a timepiece means 11 in a processing step where a light emitting diode emits the light for 3sec. This value of addition is stored in a memory 27 of the relevant processing means and at the same time a light emitting signal is supplied to a driver of the light emitting diode. While the memory time of the means 11 is increased when a reference pulse is produced and the contents of the memory 27 are updated. After such conditions are set, an information processor carries out successively other processing steps among a series of information processing steps in response to the clock signals. In this case, it is monitored during execution of other processing steps whether the replacement memory of the means 11 reaches the time (X+3) or not. When said update memory time exceeds (X+3), the information processor supplies a resetting signal to a holding circuit. As a result, the emission of light is stopped with the light emitting diode.
