First Claim
1. A broadcasting receiver having a standby state and a normal state of power supply, comprising:
- an antenna device for receiving broadcast signals;
a sub-unit operatively connected to the antenna device including a received signal processing circuit for processing said broadcast signals and a user information processing circuit for processing subscription information;
a slot operatively connected to the sub-unit for inserting a storage medium on which said subscription information is recorded;
a detecting means operatively connected to the sub-unit for detecting presence or absence of said storage medium inserted in said slot and for supplying a detection signal indicative of the presence or absence of said storage medium in said slot; and
a main unit operatively connected to said sub-unit for receiving a control signal for placing said main unit in a normal state or a standby state and for outputting a state signal indicative of the current state of said main unit to said received signal processing circuit and said user information processing circuit of said sub-unit, wherein when said received signal processing circuit and said user information processing circuit receive the state signal indicating that said main unit is in the standby state and receive said detection signal indicating the absence of said storage medium in said slot while said sub-unit is in an operating state, said received signal processing circuit and said user information processing circuit are set into a non-operating state, and wherein when said received signal processing circuit and said user information processing circuit receive said detection signal indicating the presence of said storage medium in said slot while said sub-unit is in a non-operating state, said user information processing circuit is set into an operating state and said received signal processing circuit is maintained in a non-operating state.

Abstract
An electronic apparatus according to the present invention comprises a main unit which stops operation when receiving an apparatus control signal S1 specifying a standby state while in a normal state, and then outputs an operating state signal S2 indicating that the main unit is in the standby state; and begins operation when receiving an apparatus control signal S1 for selecting the normal state while in the standby state, and then outputs an operating state signal S2 indicating that the main unit is in the normal state; and a sub-unit which stops operation when, while operating, receiving an IC card detection signal S3 indicating that the reading of an IC card 4 is possible and also receiving the operating state signal S2 indicating that the main unit is in the standby state from the main unit, and brings part of its functional blocks into operation when, while not operating, receiving the operating state signal S2 indicating that the main unit is in the normal state from the main unit.
