摘要:
A printing apparatus is capable of being driven by a battery (20) for an extended period of time without using a battery having a large capacity, and the battery (20) is capable of being charged while the occurrence of the memory effect is suppressed. Also provided is a method of charging the battery (20) in this apparatus. Battery capacity is detected in the driving interval of a carriage motor (8) and/or conveyance motor (10). When the battery capacity falls below a predetermined value, control is performed in such a manner that the driving intervals of the carriage motor (8) and conveyance motor (10) will not overlap. When charging of the battery is designated, the battery (20) is discharged using a current load in the apparatus, after which the battery (20) is charged.
摘要:
A battery-driven recording apparatus records a plurality of lines by recording-scan by using a recording head having a plurality of recording elements. A capacity of a battery is detected, and when the capacity of the battery is lowered, the number of lines to be recorded in one recording scan is reduced.
摘要:
A control signal is outputted from a CPU in a predetermined period to a one-shot circuit. An output signal of the one-shot circuit is maintained at a predetermined level, as far as the control signal is supplied to the one-shot circuit in the predetermined period. The output signal of the one-shot circuit is applied to a charging circuit for a battery. The charging circuit performs a charge operation for the battery while a predetermined level of the output signal of the one-shot circuit being kept on.
