DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving apparatus having a storage function for storing reception frequencies handled by a plurality of radio broadcasting stations classified in advance by reception area and receiving radio broadcasting of the radio broadcasting stations. Things. Specifically, an information card to which non-volatile area ID information is added in advance is prepared for each reception area, the area ID information is read from the information card, and a reception frequency group for each reception area is called, so that a wireless communication is performed in the same reception area. The reception frequency of a broadcasting station can be set easily and easily.

[0002]

2. Description of the Related Art In recent years, receivers for receiving radio broadcasts have become smaller and lighter with the development of technology, and various audio equipment such as a cassette tape recorder have been developed.
Recorder), etc., and is becoming popular among office workers and travelers on business trips. The transmission wave of the radio broadcast is, for example, a carrier wave modulated by the audio signal in order to transmit an audio signal or the like to a distant place, and the broadcast can be received by tuning the reception device to the transmission wave of the radio broadcast. . For example, a frequency modulation method (Fr
equency Modulation: Hereinafter referred to as FM. ) And an amplitude modulation method (hereinafter, referred to as AM). For example, a radio (Radio) as a receiving device that receives only an audio signal receives FM broadcast and AM broadcast using these transmission methods. In addition, audio of a television broadcast (Television broadcast: hereinafter referred to as TV broadcast) is received.

[0003] These broadcasts have different reception frequencies (channels) depending on the radio broadcasting stations to which they are transmitted, and receivable reception frequencies are assigned to respective reception areas.
Therefore, in order to receive a broadcast, a reception frequency at which a desired broadcast can be received is first selected from receivable reception frequencies assigned to a reception area.

FIG. 8 is a block diagram showing a circuit example of a receiving apparatus 200 with a storage function according to a conventional system. A receiving device 200 with a storage function shown in FIG. 8 includes a central processing unit (hereinafter, referred to as a CP) connected to a power supply.
U. ) 91 is provided to control the apparatus. C
Read-only storage device connected to PU91 (Read On
Memory: Hereinafter, ROM. ) 92 stores reception frequencies handled in advance by a plurality of radio broadcasting stations classified by reception area.

[0005] A storage device (Random Access Memory: hereafter referred to as R) in which these reception frequencies can be written and read at any time.
AM. ) 93 is connected to the CPU 91 and
When the power of the apparatus is cut off, a backup power supply for storing information in the RAM 93 is connected. The backup power supply 94 is charged by connecting the apparatus to a power supply, and stores the information in the RAM by the charged power when the power supply is cut off. A tuner 95 connected to the CPU 91 receives a radio broadcast by tuning a reception frequency and a transmission frequency from a radio broadcast station. The receiving device is provided with a setting button 96, and the setting button 96 is connected to the CPU 91 to set a receiving area and a receiving frequency.

In the conventional method, when the receiving area is first set with the setting button 96 while the power is connected, the CP
U91 stores the receivable reception frequency of the reception area in ROM
Called from 92 and written to RAM 93. Next, when a frequency is selected by the setting button 96, the CPU 91 calls a predetermined reception frequency from the receivable reception frequencies written in the RAM 93, and transmits it to the tuner 95 to receive the broadcast. At this time, the backup power supply 94 is charged. Here, in a state where the power is cut off, RA
Receivable reception frequencies in a predetermined area in M are stored until the power charged in the backup power supply 94 is consumed.

[0007]

However, the conventional receiver 200 with a storage function has the following problems. Each time the reception area is changed manually using the setting button 96, the reception frequency must be set. Therefore, there is a problem that the operability related to the setting of the reception frequency is poor. If the power supply is not connected for a long time, the power of the backup power supply 94 will be consumed and the stored information will be lost. Therefore, when the power is connected again,
The reception frequency of the reception area must be reset again manually by using the setting button 96 in the same manner. Thus, there is a problem that simplification and simplification of the setting operation of the reception frequency are prevented.

Accordingly, the present invention has been made to solve the above-mentioned problem, and a method of setting a reception frequency in a reception area has been devised so that the operability can be improved and the reception frequency can be easily adjusted. It is another object of the present invention to provide a receiving device with a storage function that can be easily set.

[0009]

SUMMARY OF THE INVENTION The above-mentioned object is to provide a storage function for storing reception frequencies handled by a plurality of radio broadcast stations classified in advance by reception areas and receiving radio broadcasts of the radio broadcast stations. In the receiving device, a storage means for storing a plurality of reception frequencies classified in advance for each reception area as a reception frequency group for each reception area, and a reception frequency group for each reception area stored in the storage means. Non-volatile area ID prepared for each reception area
Information card with information and area I of the information card
A storage means for reading out the D information and generating a memory readout signal; and a processing means for calling a reception frequency group for each reception area from the storage means based on the memory readout signal from the readout means. It is solved by a receiving device with a tag.

According to the present invention, for example, when an information card corresponding to the area is mounted on the reading means, the predetermined area ID information given to the information card is read by the reading means, and a memory read signal is generated. . Based on the memory read signal, the processing means calls the reception frequency group in the predetermined reception area stored in the storage means, so that the radio broadcast receivable in the reception area is automatically transmitted by the predetermined information card corresponding to the reception area. Can be set. Therefore, if an information card in a predetermined reception area is set in the reading means, it is not necessary to reset the radio broadcasting station in the reception area. This makes it possible to provide a receiving device with a storage function with good operability with respect to the setting of the receiving frequency.
