摘要： A mobile wireless device enables effective use of space in a case while reducing degradation of antenna gain and maintaining communication quality even if a plurality of antennas having different frequency bands are arranged close to one another. A magnetic antenna has a first switch unit, a second switch unit, and a concentrated constant circuit which are added to a wiring pattern at the side near to a main antenna, so that a first path and a second path can be selected. Under a predetermined condition, a CPU controls the first switch and the second switch to electrically connect terminal (A1) to terminal (B1) and electrically connect terminal (A2) to terminal (B2), thereby forming the first path; and electrically connect terminal (A1) to terminal (C1) and electrically connect terminal (A2) to terminal (C2), thereby forming the second path connected via the concentrated constant circuit.

摘要： An electronic apparatus which makes it possible to reduce start-up time for starting the electronic apparatus, without necessitating installment of a plurality of CPUs in the electronic apparatus. A main CPU 45 controls a digital camera implementing the electronic apparatus. A storage medium for storing information can be detachably attached to a connector 97. A medium detection circuit 85 monitors a status of attachment and detachment of the storage medium to and from the digital camera, irrespective of a status of operation of the main CPU 45. The sensed status of attachment and detachment of the storage medium is stored in a register 115 of the medium detection circuit 85.
