Abstract:
A pen-input information processing apparatus which is operable by a pen, the apparatus comprising:a pen housing which houses the pen;a processing device which has a current device state changeable between a non-operative state and an operative state, said current device state being changed when a state-transition-control-signal is activated;a suspension/resumption instruction unit;a pen-housing-detection-unit which outputs a pen-housing-detection-signal showing the existence of or non-existence of said pen in said pen housing by detecting the housing of said pen to said pen housing or detecting the pen being taken out from said pen housing, said pen housing-detection-unit being provided separately from said suspension/resumption instruction unit;a first memory unit which memorizes current device state; anda state-transition-control-unit which activates the state-transition-control-signal when said suspension/resumption-instruction-unit instructs said processing device to perform the transition of said state, said state-transition-control-unit also activating the state-transition-control-signal in a case where said current device state in said first memory unit is in the operative state and also said pen-housing-detection-signal shows the existence of said pen in said housing.
