1. An image output device provided with an injector for firing a droplet for printing, comprising:
- a memory unit for temporarily storing a data signal to be provided to said injector;
a driving unit for reading out said data signal stored in said memory unit, generating a control signal for controlling said injector, on the basis of said data signal read out from said memory unit and driving said injector based on said control signal; and
a data-update control unit for causing a data signal providing unit to suspend outputting said data signal to said memory unit in response to an identical control signal being successively provided to said injector, so that said memory unit does not update said data signal stored therein;
wherein said data signal providing unit suspends outputting said data signal to said memory unit by turning off a circuit of said data signal providing unit.

Abstract
The invention provides a semiconductor device of low power consumption and low cost. A semiconductor device 50 is basically constituted of a semiconductor substrate 1 and an external signal processing substrate 8. The semiconductor substrate 1 is provided with a memory unit 3, a data driver 4, an element array 2, a scanning circuit 35 and a clock generator 36. When successively outputting an identical data signal to the element array 2 over a plurality of times, the data signal retained in the memory unit 3 is utilized.

10. An image output device provided with an injector for firing a droplet for printing, comprising:
-
a memory unit for temporarily storing a data signal for selecting a driving waveform to be provided to said injector; a driving unit for reading out said data signal stored in said memory unit, selecting said driving waveform from a plurality of driving waveforms input from an outside source based on said data signal read out from said memory unit and driving said injector based on said selected driving waveform; and a data-update control unit for causing a data signal providing unit to suspend outputting said data signal to said memory unit in response to a same driving waveform being successively provided to said injector, so that said memory unit does not update said data signal stored therein; wherein said data signal providing unit suspends outputting said data signal to said memory unit by turning off a circuit of said data signal providing unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An image output device provided with an injector for firing a droplet for printing, comprising:
-
a memory unit for temporarily storing a data signal for selecting a driving waveform to be provided to said injector; a first driving unit for reading out said data signal stored in said memory unit, and outputting to said injector a signal for selecting, based on said data signal read out from said memory unit, said driving waveform from a plurality of driving waveforms input from an outside source; a second driving unit for providing said selected driving waveform to said injector; and a data-update control unit for causing a data signal providing unit to suspend outputting said data signal to said memory unit in response to an identical driving waveform being successively provided to said injector, so that said memory unit does not update said data signal stored therein; wherein said data signal providing unit suspends outputting said data signal to said memory unit by turning off a circuit of said data signal providing unit. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
