Abstract

PURPOSE:To store the desired frequency data on a registered broadcast station and also to secure a large number of channels to be automatically stored by conforming an auto-storing function to only the selected one among plural registered areas. CONSTITUTION:In a power-on state, a microcomputer 6 decides whether an auto-storing AS band switch key 8 is pushed or not. If pushed, a fact whether an AB is enabled to set or not to all bands (e.g. FM1-FM3) at present. If not, the AS is enabled to set to all band and AS-F1 and 23 are displayed on a display part 10 for 2-3 seconds. If the AS is enabled to set to all bands, the data are set to register (store) by fixing to a band FM3 only. Thus AS FM3 is shown on the part 10 for 2-3 seconds. Therefore it is possible to store the desired one among those frequency data on a broadcast station registered in an original area even when the receivable broadcast station moves to another separate area by a vehicle. Furthermore a large number of channels to be auto-stored can be secured even in such an area where a large number of receiving broadcast stations are included.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio receiver having an auto store function for automatically searching for radio waves coming from a plurality of broadcasting stations and registering frequency data thereof.

[0002]

2. Description of the Related Art As a radio receiver having such an auto store function, a car receiver mounted on a vehicle is widely known. Generally, a vehicle-mounted radio receiver having an auto store function has six preset channels, that is, six preset keys. Furthermore, as a band for FM broadcasting, FM1, FM
Three bands 2 and FM3 are provided for AM broadcasting, and two bands AM1 and AM2 are provided for registering a plurality of broadcasting stations.

In the broadcast station registration mode, the user can register the frequency data of the currently received broadcast station by operating a preset key. After registration, by operating the same preset key at the time of registration,
It enables so-called ISR (Instant Station Recall), which allows the broadcast station of registered frequency data to be called immediately (automatic reception). Therefore, as frequency data that can be registered, 18 channels of 3 bands and 6 channels for FM broadcasting and 12 channels of 2 bands and 6 channels for AM broadcasting can be used for a total of 30 channels.

Further, in a radio receiver having an auto store function, electric waves arriving from a plurality of broadcasting stations are automatically sought (searched) in order from a low frequency or a high frequency.
Then, when a radio wave of a predetermined level or higher is detected, the frequency data can be registered. In conventional radio receivers with an auto store function, there are two types of specifications for the auto store method.

One of them is FM1, FM2, FM3, A
This is a method of auto-storing all bands of M1 and AM2. In the radio receiver having such specifications, the memory for auto store has five registration areas, and frequency data of 6 channels can be registered in each registration area. Therefore, the user has a total of 3 channels, 18 channels for FM broadcasting and 12 channels for AM broadcasting.
A large number of auto stores of 0 channels can be performed.

[0006] The other one has a specification that can be automatically stored only in a specific band. In the radio receiver with such specifications, the memory for the auto store has FM and AM.
Each of them has one registration area, and a total of 12 channels of frequency data can be registered. For example, F
Only FM3 for M broadcasting, A for AM broadcasting
Auto-store only on M2, so-called SAM (Sin
gle Auto Memory) specifications.

[0007]

However, in the above conventional radio receiver having the auto store function, the contents of all the registration areas are changed when the auto store mode is set in the case of the specification of the method of auto storing in all bands. Since the data is updated, there is a problem that the frequency data of the already registered broadcasting station, which is desired to be saved, may be deleted due to the movement of the vehicle or the influence of surrounding buildings.

On the other hand, in the specification of the method of auto-storing only in a specific band, there is a problem that the number of channels to be auto-stored becomes insufficient in the area where the radio waves of many broadcasting stations are received.

The present invention solves the problem of the prior art as described above. According to the user's selection, it is possible to save the frequency data of the already registered broadcasting stations that should not be erased, and the number of channels to be automatically stored. The purpose is to provide an excellent radio receiver that can secure many.

[0010]

In order to achieve this object, the present invention has a predetermined number of preset keys, a storage means having a plurality of registration areas in which the predetermined number of frequency data can be respectively registered, and a plurality of the storage means. A configuration is provided that includes a selection unit that selects one or more or all of the registration areas.

[0011]

According to the present invention, with the above-described structure, the auto store function is performed only in the selected registration area among the plurality of registration areas, so that the frequency data of the already registered broadcasting station can be erased as needed by the user. You can save things you don't want, and you can secure a large number of channels to auto store.
