PURPOSE:To enable to use effective multi-functions as well as the selective use of a plurality of reception units, by reading out the reception frequency of a plurality of specific memory section through the control circuit at the selective selection of a plurality of memory units by the selective unit. CONSTITUTION:The memory units 16 and 17 have respectively the reception frequency memories 16a and 17a, the selective unit 21 selects one of the units 16 and 17 and tuning is made to the reception frequency read out with the tuning circuit 80. Further, the units 16 and 17 have respectively the specific memory sections 16b and 17b storing the final reception frequency at access operation, and at the selective selection and power application of the units 16 and 17 by the selective unit 21, the reception frequency of the specific memory sections 16b and 17b is read out. Thus, regardless of the usage of a single reception ununit, a plurality of reception units can be used with selection and effective and multi-functional usage can be made. |
