Description

【０００１】
【発明の属する技術分野】
この発明は携帯電話機、詳しくは、故障の原因を探求し易くした携帯電話機に関するものである。
【０００２】
【従来の技術】
携帯電話機は、近年急速に使用台数が増加しており、現代生活の必需品となっている。しかしながら、携帯電話機は極めて精密な電子機器であり、乱暴に取扱うとその機能に重大な障害が発生することは避けられなかった。携帯電話機の使用時に発生する故障の多くは、衝撃、高温、浸水によるものである。
【０００３】
【発明が解決しようとする課題】
故障したときは、クレームの対象としてメーカー側が修理の責任を負わなければならない場合と、誤った使用によるものとしてユーザー側が自己の負担で修理しなければならない場合とがあるが、その認定を巡ってメーカー側とユーザー側とで争いとなる場合がある。
【０００４】
落下による衝撃や浸水の場合には携帯電話機の外部や内部にその痕跡がはっきりと残ることが多く、故障原因を探求して責任の所在を特定し易いが、高温雰囲気中に晒された場合の故障つまり高温障害は、外観上の変化がほとんど認められぬ為、原因探求が困難となり、故障についての責任の所在が明らかにならず、修理負担を巡りトラブルとなり易かった。
【０００５】
携帯電話機においては、表示部を中心に液晶機器が多く用いられているが、液晶機器は熱に弱く、一般的には６０℃を超えると、その機能に障害が発生すると言われており、携帯電話機の使用条件も６０℃以下に設定され、ユーザーがそれ以上の高温雰囲気中に晒した場合にはクレーム扱いによる無償修理に応じないとしているケースが多い。
【０００６】
しかしながら、炎天下の密閉された車両のダッシュボード上などに不用意に携帯電話機を放置した場合などには、簡単にこの６０℃を超えてしまう為、メーカー側としては修理に持ち込まれた携帯電話に温度限界を超えた事実があったか否かを的確に把握できることが、クレーム対策上からも必要だった。
【０００７】
携帯電話機の内部に、ユーザーが勝手にいじれない様な状態で何らかの温度記録装置を設置しておけば、故障修理の際にこの記録装置の記録から温度上昇の履歴を把握して責任の所在を明らかにできるが、最近の携帯電話機は軽量化、小型化、高密度実装化が極限まで進んでおり、その内部には温度記録装置を設置できる余積はほとんど残されていないのが現状であり、高温による故障を的確に把握する手立てはほとんどなかった。
【０００８】
本発明は、上記現状に鑑み開発されたものであり、限界を超えた温度による携帯電話機の故障発生の際、故障原因を明確に特定して責任の所在を明らかにでき、クレームに対して的確に対処できる様にした携帯電話機に関するものである。
【０００９】
【課題を解決するための手段】
シ−ト状をしたワックス吸収体１１の表面側にあらかじめ設定された温度で融解するワックス７を重畳し、その上に片面が彩色面１２となっており、ワックス７が融解浸透すると不透明から透明に変化する性質を有する物質からなるシ−ト状の基材６を彩色面１２をワックス７側にして重畳し、ワックス吸収体１１の裏面に両面接着テープ９を貼付すると共に、表面側全体を透明フィルム１０で被覆した構造からなり、あらかじめ設定された温度に達すると発色して温度低下後もその発色状態をそのまま持続する不可逆性温度表示ラベル５を、電話機本体１の電池装着用凹部４内や電池パック３の裏面１４に貼付することにより、上記課題を解決せんとするものである。又、温度表示ラベル５は、片面が彩色面１２となっており、ワックス７が融解浸透すると不透明から透明に変化する性質を有する物質からなるシ−ト状基材６の非彩色面側に固体状ワックス層１３を形成せしめ、彩色面１２側を裏面側として、これに両面接着テープ９を貼付すると共に、ワックス層１３を表面側として表面側全体を透明フィルム１０で被覆した構造からなるものも用いることができる。
【００１０】
【発明の実施の形態】
図１はこの発明に係る携帯電話機の一実施例の斜視図である。図中１は電話機本体であり、その裏面側２には電池パック３を取付ける電池装着用凹部４が形成されている。そして、この電池装着用凹部４の適当位置には、あらかじめ設定された温度に達すると発色し、温度低下後もその発色状態を持続する不可逆性温度表示ラベル５が貼付されている。なお、温度表示ラベル５は電池装着用凹部４ではなく、電池パック３の裏面１４に貼付しても良い。叉、電池装着用凹部４と電池パック３の双方に貼付しても良い。
【００１１】
この実施の形態において用いた温度表示ラベルは図２に示す様に、一方の面に
シ−ト状をしたワックス吸収体１１の表面側にあらかじめ設定された温度で融解するワックス７を重畳し、その上に片面が彩色面１２となっており、ワックス７が融解浸透すると不透明から透明に変化する性質を有する物質からなるシ−ト状の基材６を彩色面１２をワックス７側にして重畳し、ワックス吸収体１１の裏面に両面接着テープ９を貼付すると共に、表面側全体を透明フィルム１０で被覆したものであり、この温度シール５が貼付けられている部位があらかじめ設定されている規定温度を超えると、ワックス７は融解してその表面側に位置している基材６に浸透し、これを透明化させ、基材６の彩色面１２が透けて見える状態、つまり不可逆的な発色状態になる。なお、この温度表示ラベル５は薄い板状をなしており、この実施の形態においては、その厚さは１ｍｍ以下である。
【００１２】
そして、この温度表示シール５の電池装着用凹部４あるいは電池パック３の裏面１４への貼付は温度記録の改ざんあるいは隠滅を防ぐ為、ユーザーが勝手に剥がせない様に強固に行うことが望ましい。叉、その貼付位置は、図１に示す様に電池装着用凹部４の左上部などに限る必要はなく、どこに貼付しても良いが、目立たぬ箇所が望ましい。更に、この温度シール５の上面に目隠し用のシール等を貼付しても良い。
【００１３】
叉、温度表示ラベル５として、図３に示す様に、片面が彩色面１２となっており、ワックス７が融解浸透すると不透明から透明に変化する性質を有する物質からなるシ−ト状基材６の非彩色面側に固体状ワックス層１３を形成せしめ、彩色面１２側を裏面側として、これに両面接着テープ９を貼付すると共に、ワックス層１３を表面側として表面側全体を透明フィルム１０で被覆したものを用いても良い。
【００１４】
この実施の形態は上述の通りの構成を有するものであり、温度表示ラベル５の発色温度をあらかじめ６０℃に設定しておくと、電話機本体１が６０℃を超える雰囲気中に晒された場合、電池装着用凹部４内あるいは電池パック３の裏面に貼付されたこの温度表示ラベル５が発色し、限界温度超過の事実を記録する。なお、この温度表示ラベル５は不可逆性であるので、一旦限界温度を超過した後、雰囲気中の温度が設定温度以下に低下してもその発色はいつまでも継続され記録が消去されることはない。
【００１５】
従って、メーカーとしては、携帯電話機が故障であるとしてユーザーから修理あるいは交換の要求があったとしても、この電池装着用凹部４内あるいは電池パック３の裏面１４の温度表示ラベル５を見ることにより、高温障害による故障か否かを即座に判別でき、故障についての責任当事者を明確にすることが可能となる。
【００１６】
【発明の効果】
この発明に係る携帯電話は上述の通り、限界温度を超えた事実があるか否かを明確かつ即座に判断することができるので、商品管理及びアフターサービスをより有効に実施することができる効果を有する。叉、シート状をなした１ｍｍ以下の極薄い温度表示ラベルを貼り付けるだけなので、携帯電話本体の小型化の妨げには全くならず、コスト的にも大きな負担とはならず、極めて高い実用的価値を有するものである。

BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone, and more particularly to a mobile phone that facilitates searching for the cause of a failure.
[0002]
[Prior art]
The number of mobile phones used has increased rapidly in recent years and has become a necessity for modern life. However, the mobile phone is an extremely precise electronic device, and it has been inevitable that a serious failure will occur in its function when handled roughly. Many of the failures that occur when using a mobile phone are due to impact, high temperature, and flooding.
[0003]
[Problems to be solved by the invention]
In the event of a failure, the manufacturer may be responsible for the repair as a subject of the complaint, and the user may have to repair at his own expense as a result of incorrect use. There may be a dispute between the manufacturer and the user.
[0004]
In the case of impact or inundation due to falling, the traces often remain clearly on the outside or inside of the mobile phone, and it is easy to find the cause of failure by identifying the cause of failure, but when exposed to high temperature atmosphere The failure, that is, the high temperature failure, hardly changed in appearance, so it was difficult to find the cause, the location of the responsibility for the failure was not clarified, and it was easy to cause trouble over the repair burden.
[0005]
In mobile phones, liquid crystal devices are often used mainly for display units. However, liquid crystal devices are vulnerable to heat, and it is generally said that when the temperature exceeds 60 ° C., the function is impaired. The telephone usage conditions are also set to 60 ° C. or lower, and if the user is exposed to a higher temperature atmosphere than that, there are many cases where the customer does not accept free repairs by handling claims.
[0006]
However, if the mobile phone is left unintentionally left on the dashboard of a car that is sealed under the sun, it will easily exceed 60 ° C. From the point of view of complaints, it was necessary to accurately grasp whether there was a fact that the temperature limit was exceeded.
[0007]
If a temperature recording device is installed inside the mobile phone in such a way that the user cannot tamper with it, the temperature rise history can be ascertained from the recording device's records at the time of fault repair. Clearly, the latest mobile phones are lighter, smaller, and more densely packed, and there is almost no room left to install a temperature recording device. There was almost no way to accurately grasp failures due to high temperatures.
[0008]
The present invention has been developed in view of the above situation, and when a mobile phone failure occurs due to a temperature exceeding the limit, the cause of the failure can be clearly identified and the location of responsibility can be clarified. It relates to a mobile phone that can cope with the above.
[0009]
[Means for Solving the Problems]

When the wax 7 melts and penetrates, it becomes opaque to transparent. A sheet-like base material 6 made of a material having a property of changing to the above is superposed with the coloring surface 12 facing the wax 7 side, and a double-sided adhesive tape 9 is pasted on the back surface of the wax absorber 11, and the entire surface side is covered. An irreversible temperature display label 5 which has a structure covered with a transparent film 10 and develops a color when a preset temperature is reached and maintains the colored state even after the temperature is lowered is provided in the battery mounting recess 4 of the telephone body 1. Or by attaching it to the back surface 14 of the battery pack 3. The temperature display label 5 has a chromatic surface 12 on one side, and is solid on the non-colored surface side of the sheet-like substrate 6 made of a material having a property of changing from opaque to transparent when the wax 7 melts and penetrates. In addition, a wax layer 13 is formed, and the double-sided adhesive tape 9 is applied to the colored surface 12 side as the back surface side, and the entire surface side is covered with the transparent film 10 with the wax layer 13 as the surface side. Can be used.
