Abstract

Abstract An automatic station searching device for a radio receiver in which the order in which the station data is stored in a memory device can be altered so that the user can easily selected between storage in the order of signal strength or storage in the order of frequency. Frequency and signal strength data for received stations are stored in order of signal strength during the sweeping operation. At the end of the sweeping operation, the data are rearranged in order of frequency if a memory bit has been set to so indicate.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 131 words
In an automatic station searcher for a receiver comprising: means for automatically sweeping within a received frequency band in response to a station search command signal as broadcasting stations are received, and means for storing data, obtained during sweeping, on received broadcasting stations having higher intensities of electric fields with priority in a presetting storage section, the improvement comprising: station search commmand signal generating means for producing said station search command signal; and a control section for determining if said command signal from said generating means has been produced during sweeping, said control section comprising means for rearranging, after sweeping is completed, data stored in said presetting storage section into a prescribed order in response to a determination by said control section that said command signal has been produced during sweeping.
Claim 2
Dependent Claim 131 words
In an automatic station searcher for a receiver comprising: means for automatically sweeping within a received frequency band in response to a station search command signal as broadcasting stations are received, and means for storing data, obtained during sweeping, on received broadcasting stations having higher intensities of electric fields with priority in a presetting storage section, the improvement comprising: station search commmand signal generating means for producing said station search command signal; and a control section for determining if said command signal from said generating means has been produced during sweeping, said control section comprising means for rearranging, after sweeping is completed, data stored in said presetting storage section into a prescribed order in response to a determination by said control section that said command signal has been produced during sweeping.
Claim 3
Dependent Claim 55 words
The automatic station searcher according to claim 1, further comprising means for attaining at least one of first and second states in response to the determination by said control section that said command signal has been produced during sweeping, wherein said control section rearranges said data depending on the state of said means for attaining.
Claim 4
Dependent Claim 65 words
The automatic station searcher according to claim 2, wherein said at least first and second states indicate whether a number of times of production of said command signal during sweeping is odd or even, and said control section rearranges said data stored in said presetting storage section when the number of times of production of said station search command signal during the sweeping is odd.
Claim 5
Dependent Claim 51 words
The automatic station searcher according to claim 2, further comprising display means driven by said control section during said sweeping, said control section switching said display means between different display modes indicative of the state of said means for attaining when said station search command signal is produced during said sweeping.
Claim 6
Dependent Claim 20 words
The automatic station search of claim 2, wherein said means for attaining comprises one of a memory and a counter.
Claim 7
Dependent Claim 15 words
The automatic station searcher of claim 1, wherein said prescribed order is in increasing frequency.
Claim 8
Dependent Claim 142 words
An automatic station searcher for a receiver comprising: means for automatically sweeping within a received frequency band in response to a first production of a station search command signal as broadcasting stations are received; means for storing data, obtained during sweeping, on received broadcasting stations having higher intensities of electric fields with priority in a presetting storage section; station search command signal generating means for producing said station search command signal; and a control section for determining when said command signal from said generating means is produced during sweeping, said control section comprising means for attaining at least one of first and second states in response to production of said command signal during sweeping, and means for rearranging, after sweeping is completed, data stored in said presetting storage section into a prescribed order depending upon the state of said means for attaining.
Claim 9
Dependent Claim 142 words
An automatic station searcher for a receiver comprising: means for automatically sweeping within a received frequency band in response to a first production of a station search command signal as broadcasting stations are received; means for storing data, obtained during sweeping, on received broadcasting stations having higher intensities of electric fields with priority in a presetting storage section; station search command signal generating means for producing said station search command signal; and a control section for determining when said command signal from said generating means is produced during sweeping, said control section comprising means for attaining at least one of first and second states in response to production of said command signal during sweeping, and means for rearranging, after sweeping is completed, data stored in said presetting storage section into a prescribed order depending upon the state of said means for attaining.
Claim 10
Dependent Claim 20 words
The automatic station searcher of claim 7, wherein said means for attaining comprises one of a memory and a counter.
Claim 11
Dependent Claim 15 words
The automatic station searcher of claim 7, wherein said prescribed order is in increasing frequency.
