Description
【考案の詳細な説明】 ［産業上の利用分野］ 本考案は多バンド受信機に係り、特に該受信機のバンド
切換方式の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a multi-band receiver, and more particularly to improvement of a band switching system of the receiver.
［考案の概要］ 多バンド受信機において、バンド切換釦の押圧時間を計
測して、所定値未満であれば受信バンドを切換えるが、
所定時間以上であると同一バンド内の別の放送局に切換
えるようにしたものである。[Outline of Device] In a multi-band receiver, the pressing time of the band switching button is measured, and if the value is less than a predetermined value, the receiving band is switched.
If the time is longer than a predetermined time, the broadcasting station is switched to another broadcasting station in the same band.
［従来の技術］ 従来の電子同調式ラジオ受信機は周波数切換釦を押すた

の押圧回数が増加することになる。[Problems to be Solved by the Invention] According to the conventional band switching method described above, it is difficult to avoid an increase in the number of switching buttons when a large number of presets are made in the former method. In the latter method, even in the AM band, AM
If the user wants to be able to select 1 , AM 2, etc., the number of times the switching button is pressed increases.
［考案の目的］ 従って本考案の目的は多数プリセットしてもバンド切換

くてもよく、またその押圧回数も増加しない。[Operation] If the pressing time of the band switching button is equal to or less than the predetermined value, the reception band is switched, but if it is equal to or more than the predetermined value, another broadcasting station is switched within the same band. Therefore, even if a large number of band switching buttons are preset, it is not necessary to increase the number of band switching buttons so much, and the number of times of pressing does not increase.
