【発明の詳細な説明】 （産業上の利用分野） 本発明は、着脱自在の受信電界レベル表示器を有する携
帯無線電話機に関する。Description: TECHNICAL FIELD The present invention relates to a portable wireless telephone having a detachable reception electric field level indicator.
（従来の技術及びその問題点） 従来、この種の携帯無線電話機は、受信電界レベル表
示，ダイヤル表示等の表示部，送話部，受話部，テンキ
ーにより成るキーボード部、アンテナ及び無線送受信部
から構成されており、受信電界レベル表示器は携帯無線
電話機本体にのみ設けていた。(Prior art and its problems) Conventionally, this type of mobile radio telephone includes a display unit for receiving electric field level display, dial display, a transmitter unit, a receiver unit, a keyboard unit including ten keys, an antenna, and a wireless transmission / reception unit. However, the reception electric field level indicator was provided only on the main body of the mobile phone.
この携帯無線電話機を使用するには、まず、本体表示部
の受信電界レベル表示を見て受信電界が有るか無いかを
確かめる。もし受信電界が無ければ、受信電界レベル表
示を見ながら受信電界が強い場所に携帯無線電話機を移
動する。そして、携帯無線電話機が使えることを確認し
た後、電話番号をテンキーで入力して発呼し、携帯無線
電話機の頭側の受話部を耳に当てて通話する。To use this portable radio telephone, first, see the received electric field level display on the main body display section to check whether or not there is a received electric field. If there is no received electric field, the portable radio telephone is moved to a place where the received electric field is strong while observing the received electric field level display. Then, after confirming that the portable radio telephone can be used, a telephone number is input with a ten-key pad to make a call, and the earpiece on the head side of the portable radio telephone is put on the ear to make a call.
受信電界の強い場所においては、携帯無線電話機を手に
持ちテンキーを押して電話番号を入力するときの受信電
界と、携帯無線電話機を耳に当てて通話するときの受信
電界とは殆ど差がない。In a place where the received electric field is strong, there is almost no difference between the received electric field when the portable wireless telephone is held in the hand and the numeric keypad is pressed to input a telephone number, and the received electric field when the portable wireless telephone is put on the ear to talk.
ところが、受信電界の比較的弱い場所においては、フェ
ージングの影響を受け、テンキーを押して電話番号を入
力する状態と通話状態とでは受信電界が大きく変わって
しまう。However, in a place where the received electric field is relatively weak, it is affected by fading, and the received electric field greatly changes between the state of pressing the numeric keypad to input a telephone number and the state of talking.
したがって、電話番号を入力した後、通話する際に通話
断となったり、通話中においてもSN比が劣化する等の不
具合が生ずるという問題があった。Therefore, there is a problem that a call is disconnected when a call is made after inputting a telephone number, or a SN ratio is deteriorated even during a call.
また、良好なSN比で通話し始めることができたとして
も、通話中に場所を移動した場合には、SN比が劣化した
り、通話断となる等の不具合が生ずることがある。Even if the call can be started with a good SN ratio, when the place is moved during the call, the SN ratio may be deteriorated or the call may be disconnected.

てあることを特徴とする。(Means for Solving Problems) A portable radio telephone provided by the present invention for solving the above problems is a reception electric field level indicator main body and a cord connected to the reception electric field level indicator main body. And a reception electric field level indicator including a plug connected to the tip of the cord is detachably attached to the main body of the portable radio telephone.
