Abstract

PROBLEM TO BE SOLVED: To prevent the misoperations of a portable terminal equipment with its back lights kept turned off just by turning on the back light as the first input operation carried out to an input part while the back light kept turned off and then validating the operations of the terminal equipment from the next input operation.
SOLUTION: If a user forgets to turn off the back lights 3 and 5 of a portable terminal equipment in a bright environment, both lights 3 and 5 are compulsively turned off by means of an illuminance sensor 6 for reduction of the power consumption. Furthermore, the lights 3 and 5 are automatically turned off by a timer 8 even in a dark environment when the terminal equipment is not operated for a fixed time or longer. When the user tries to perform an input operation in the automatic turn-off mode, the user is unable to identify an input part 4 and a display part 2 since the lights 3 and 5 are kept turned off. Therefore, both lights 3 and 5 are just turned on as the first input operation and no input processing is carried out so as to prevent the misoperations. When both lights 3 and 5 are turned on, the parts 4 and 2 can be correctly identified and therefore accurately operated.

【0001】 [0001]

【発明の属する技術分野】本発明は自動点灯・消灯バックライト付き携帯端末装置に関する。 The present invention relates to relates to a portable terminal device with automatic turning on and off the backlight.

【0002】 [0002]

【従来の技術】従来のバックライト付き携帯端末装置は一定時間以上入力操作がない場合は、電池の消耗を防ぐために自動的にバックライトを消灯する。 It is BACKGROUND OF THE INVENTION portable terminal device with a conventional backlight if there is no input operation more than a predetermined time, automatically turns off the backlight to conserve battery. このようなバックライト付き携帯端末装置としては、特開平1−23 As such a backlight-equipped mobile terminal device, JP-A-1-23
7810号公報(バックライト自動点燈、消燈装置)がある。 7810 JP (backlight automatic point lamp, erasing lamp unit) is.

【0003】従来のバックライト自動点灯・消灯機能を備えた携帯端末装置では表示が見えない状態で入力部を操作するため、誤った操作をする場合があった。 [0003] Since the portable terminal apparatus having a conventional backlight automatic turning on and off function of operating the input section in a state where the display is not visible, there is a case where the erroneous operation.

【0004】 [0004]

【発明が解決しようとする課題】バックライトは周囲が暗い時、つまり表示が見えない時に点灯する。 Backlight [0008] is turned on when when the ambient is dark, that is, the display is not visible. 電池の消耗を防ぐために消灯している場合、当然表示が見えない。 If you are turned off in order to prevent the consumption of the battery, the display can not be seen of course.

【0005】従って、キーやタッチパネルなど入力部を操作した場合、誤った操作をしてしまうという問題点があった。 [0005] Therefore, when operating the input unit such as a key or a touch panel, there is a problem arises in that the wrong operation.

【0006】本発明の目的は、誤った入力操作を防ぐために、消灯している状態において、最初の入力操作ではバックライトを点灯する動作だけとし、データ入力などの入力操作と見做さなずにすることにより、誤操作を防ぐことにある。 An object of the present invention, in order to prevent erroneous input operation, in a state in which off, in the first input operation and only operation of turning on the backlight, an input operation regarded Sanazu such as data input by the, it is to prevent erroneous operation.

【0007】 [0007]

【課題を解決するための手段】本発明の特長は誤操作を防ぐために、最初の入力操作はバックライトを点灯するだけであり、データ入力などの入力操作と見做さない。 To prevent erroneous operation features of the present invention SUMMARY OF THE INVENTION The first input operation is simply turning on the backlight, no input operation regarded such as data input.
実際のデータ入力操作はバックライトが点灯し表示が見える状態で行うので、誤った入力操作をすることはない。 Because the actual data input operation is carried out in a state in which the backlight is visible display light, and not to the erroneous input operation.

【0008】バックライトを点灯してから入力操作を有効にするので、誤った入力操作をすることはない。 [0008] because to enable the input operation after turning on the backlight, there is no possibility that the erroneous input operation.

【0009】 [0009]

【発明の実施の形態】以下、本発明の実施例を図面を用いて説明する。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, will be explained with reference to the drawings an embodiment of the present invention. 図1に本発明の一実施例の構成を示す。 It shows the structure of an embodiment of the present invention in FIG.
本発明によるバックライト付き携帯端末装置では、タッチパネルやテンキーなどによる入力部1および入力部4 In the portable terminal device with a backlight according to the present invention, the input unit 1 and the input unit 4 by a touch panel or a numeric keypad
と液晶などによる表示部2と表示部2および入力部1および入力部4を照光するバックライト3およびバックライト5と照度を測定する照度センサ6とマイクロコンピュータと入出力回路などからなる制御部7と一定時間ごとに割込みを発生するタイマ8とメモリ9と各部に電力を供給する電池部10によって構成される。 A backlight 3 and a backlight 5 and the controller 7 composed of a luminance sensor 6 and the microcomputer and input-output circuit for measuring the illuminance to illuminate the display unit 2 and the display unit 2 and the input unit 1 and the input unit 4 by a liquid crystal and it constituted by the timer 8 and the memory 9 and the battery unit 10 supplies power to each unit to generate an interrupt at regular intervals. 表1に使用するメモリ9上のレジスタや入出力ポートの例を示す。 Using Table 1 shows an example of a register and output ports of the memory 9.

【0010】図2に入力割込み処理の例を示す。 [0010] An example of an input interrupt processing in FIG. 図3にタイマ割込み処理の例を示す。 An example of a timer interruption processing in FIG.

【0011】 [0011]

【表1】 [Table 1]

【0012】使用者は入力部1の表示および表示部2を見て入力部1および入力部4を用い、データを入力する。 [0012] The user sees the display and the display section 2 of the input unit 1 using the input unit 1 and the input unit 4 inputs the data. 周囲が暗くなり入力部1の表示および表示部2の識別が困難になった場合、使用者は入力部1または入力部4を操作して点灯許可レジスタBLENBLRおよび点灯許可ポートBLENBLPをオンに設定し、バックライト3および5を点灯する。 If it becomes difficult to distinguish the display and the display section 2 of the input section 1 around becomes dark, the user sets to select the lighting enable register BLENBLR and lighting authorized port BLENBLP by operating the input unit 1 or the input unit 4 It turns on the backlight 3 and 5. バックライト3および5は電力を消費するため必要でないときに点灯させると電池寿命が短くなる。 Battery life is shortened when the backlight 3 and 5 are turned on when not needed for consuming power. 周囲が明るくなっても使用者が点灯許可レジスタBLENBLRおよび点灯許可ポートBLE Also user lights allow the ambient becomes brighter register BLENBLR and the lighting-authorized port BLE
NBLPをオフに設定するのを忘れた場合、電力消費を低下させるために照度センサ6を用いて強制的にバックライト3および5を消灯する。 If you forget to set off NBLP, forcibly turns off the backlight 3 and 5 using the illuminance sensor 6 in order to reduce the power consumption. また周囲が暗い場合でも、一定時間以上操作していない場合、操作していないと判定し、バックライト3および5を消灯する。 Even in a dark environment, when not operated a predetermined time or more, determined not to be operated, turns off the backlight 3 and 5.

【0013】自動点灯・消灯の方法におけるキー割込みおよびタイマ割込みフロー例を図2および図3に、使用するレジスタの例を表1に示す。 [0013] The key interrupt and the timer interrupt flow example of the method of automatic illumination and extinction in FIGS. 2 and 3 show an example of the registers used in Table 1. タイマ割込みではバックライトタイマBLTIMERを減算し、時間パラメータBLTIMEIで予め設定した時間以上入力操作が行われない場合、操作していないと判定する。 The timer interrupt subtracts the backlight timer BLTIMER, if the input operation is not performed preset time or a time parameter BLTIMEI, determines that no operation. 操作していないと判定した場合、点灯許可ポートBLENBLPをオフに設定しバックライト3および5を消灯する。 If it is determined that it is not operated, it sets off a lighting authorized port BLENBLP turns off the backlight 3 and 5. 時間パラメータBLTIMEIで予め設定した時間以内に入力操作がある場合は、入力割込み処理でバックライトタイマBLTIMERを時間パラメータBLTIMEIの値にリセットしてバックライト3および5の点灯を継続する。 If time is an input operation within preset time parameter BLTIMEI, it resets the backlight timer BLTIMER the value of the time parameter BLTIMEI input interrupt processing continues lighting of the backlight 3 and 5.

【0014】自動消灯時に再度使用者が入力操作を行おうとした場合、バックライト3および5が消灯しているため、入力部4や表示部2を識別することができない。 [0014] If the re-user during auto off attempts to perform input operation for the backlight 3 and 5 are off, it is impossible to identify the input unit 4 and the display unit 2.
このため誤って入力部1および4を操作してしまう場合がある。 Therefore incorrectly in some cases by operating the input unit 1 and 4.

【0015】誤操作を防ぐために、最初の入力操作ではバックライト3および5を点灯するだけとし、入力処理は行わない。 [0015] In order to prevent erroneous operation in the first input operation and only turning on the backlight 3 and 5, the input process is not performed. バックライト3および5が点灯したあとは入力部4や表示部2を識別することができるので、正確に入力部1および4を操作することができる。 Since after the backlight 3 and 5 is lit can identify the input unit 4 and the display unit 2 can operate exactly the input unit 1 and 4.

【0016】 [0016]

【発明の効果】使用者はバックライトが点灯し表示が見える状態になってから、入力操作を行うため誤操作を行うことはない。 User, according to the present invention from the ready to backlight visible display light, and not to perform an erroneous operation for inputting operation.
