Description

输入装置
技术领域
本发明涉及能够在同一操作面上进行按钮输入和坐标输入的输入装置。
背景技术
在移动电话等的输入装置中，设置按钮式的输入部分等，能够进行电话号码的输入、通话的开始和结束等各种操作。
最近，存在利用移动电话的因特网连接环境增加的倾向，用移动电话来进行各种服务的提供。由此，在移动电话的显示器上显示各种菜单，而频繁地进行菜单的选择操作。
在用现有的输入装置来进行菜单的选择的情况下，与设在移动电话上的上述按钮式的输入装置不同，设置表示方向的按压式和操纵棒式的输入装置，来移动菜单的能够选择的位置。
发明内容
但是，在上述现有的输入装置中，按钮式的输入操作和菜单选择的输入操作由不同的输入部分完成，而存在不利于操作性的问题。而且，在现有的输入装置上，使菜单移动的方向被限制在上下方向和左右方向上，因此，难于进行快速的菜单选择。
为了解决上述问题，本发明的目的是提供一种输入装置，不损害操作性，而能够进行按压预定的输入位置的操作和菜单选择等的光标移动操作。
而且，本发明的目的是提供能够确实地识别操作者的按压的输入装置。
本发明具有：能够进行坐标输入的平面型的输入部分；设在上述输入部分的表面上来指示多个输入位置的显示部；提供来自上述输入部分的输入信号并根据上述输入信号而生成操作信号的控制部，其特征在于，
当通过上述控制部而设定为预定的输入方式时，检测接触到上述输入位置的情况，生成与上述输入位置的指示项目相对应的操作信号，当设定为另一种输入方式时，与上述输入位置的显示无关，作为坐标数据而识别来自上述输入部分的输入信号。
在上述的本发明中，能够在同一操作面上进行输入位置的操作和与输入位置无关的坐标数据的输入操作，因此，不会使手指进行较大的移动，不会损害操作性。
例如，在上述输入部分上同时设置显示装置，当设定为上述另一种输入方式时，上述显示装置进行与上述坐标数据相对应的显示。
而且，特别是设置操作触觉发生装置，当按压上述显示部上所显示的上述输入位置时，提供该按压的反作用力。
上述操作触觉发生装置可以单独设置在与上述显示部上所显示的输入位置相对应的位置上，也可以仅设置在上述输入部分的里侧的一个位置上。
上述操作触觉发生装置可以通过位于输入部分里侧的圆顶状的反转板所形成。
由此，能够向操作者提供按压的识别，能够防止忘记按压等来确实地进行操作。
能够通过上述反转板进行开关输入。
在此情况下，由于在反转板被反转之前，不会进行开关输入，而防止仅通过接触显示部而被输入的情况。
根据上述的本发明，能够在同一操作面上进行生成与输入位置相对应的操作信号的输入方式和生成坐标数据的输入方式，因此，不会损害操作性，能够进行快速的输入操作。
而且，当输入位置被按压操作时，向操作者提供发生的按压反作用力，使操作者能够确实地识别操作动作，而能够抑制操作错误。

具体实施方式
图1所示的输入装置1是移动电话，在外壳2中装载了作为显示装置的显示屏3和作为输入部分的平面型输入装置4。显示屏3由单色型和彩色型的液晶屏或者EL屏组成。
平面型输入装置4可以是感压型和静电电容型的。作为静电电容型，由Ag(银)类膏所形成的X方向检测电极和Y方向检测电极，在由具有绝缘性并且具有预定的介电常数的PET(聚对苯二甲酸乙二酯)等所形成的树脂片的上下，相对地形成为矩阵状。这样，树脂片和电极配置在树脂片上形成导电图形的基板上，由此，能够实现弯曲变形。由此，通过手指等介电体接触到平面型输入装置4的表面，能够进行输入坐标的任务。
作为感压式，具有在X和Y方向上提供电位差的电阻体和与上述电阻体相对的导电体，通过用手指等按压，使上述导电体和上述电阻体进行接触，则电阻值发生变化，由此，能够实现坐标的输入。
而且，在平面型输入装置4上，在成为操作侧的表面上层叠并固定显示片(显示部)7(参照图1和图2)。显示片7由PET等树脂片所形成，在其表面上印刷数字和符号等多个输入位置8。而且，在数字和符号上形成表示能够输入的位置的圆形的框，在该框内形成数字和符号。
在上述平面型输入装置4的里侧形成操作触觉发生装置6。上述操作触觉发生装置6，在外壳2内设置玻璃环氧树脂和金属的基座9，在该基座9上设置圆顶状(膜片状)的反转板10。该反转板10单独设置在与上述输入位置8相对应的位置上。
在图2的A所示的操作前的状态下，平面型输入装置4和显示片7都不变形，反转板10处于维持圆顶状的原来的形状的状态下。在此状态下，当通过手指和笔等按压所希望的输入位置8时，平面型输入装置4和显示片7同时弯曲变形而成为凹进状态。通过此时的压入力，使上述反转板10反转，其结果，产生反转板的按压反作用力。该按压反作用力作为喀哒感觉传递到操作者的手指上，向操作者提供确实地进行了按压的识别。
如图3所示的那样，在上述输入装置1上设置控制部21。在控制部21上连接上述的显示屏3和平面型输入装置4，来进行控制，而且，连接发送部22、接收部23和存储部24。用发送部22和接收部23来进行同外部的声音信号和数据信号的发送接收，用存储部24来存储电话号码数据、各种设定数据和在显示屏3上所显示的显示数据等。
上述控制部21能够进行预定的输入方式和另一种输入方式的两种不同的输入。当预定的输入方式被设定时，检测用手指按压上述输入位置8的动作，来提供与在输入位置8上所显示的指示项目相对应的输入信号，根据该输入信号来生成操作信号。而且，当另一种输入方式被设定时，与上述输入位置8的显示无关，检测通过手指滑过上述平面型输入装置4的表面的动作，提供输入信号。在该另一种输入方式的情况下，上述输入信号作为坐标数据被识别，而生成操作信号。
当被设定为预定的输入方式时，在上述显示屏3上进行能够执行数字等的输入操作的显示。而且，当被设定为另一种输入方式时，在上述显示屏3上进行能够执行菜单的选择的显示，或者，进行显示光标来使该光标能够移动的显示等。
例如，当在显示屏3上显示因特网中的主页(网页)画面时，在显示屏3上显示光标，能够通过平面型输入装置4的输入操作使上述光标在X-Y平面上向所有方向自由地移动。而且，当移动光标而决定了菜单的选择位置时，接着进行决定上述菜单的操作，但是，该决定的操作可以通过例如扣击平面型输入装置4的表面的动作(轻敲)来执行，或者，通过在外壳2中平面型输入装置4之外另设置的操作部件的操作来执行。而且，上述轻敲的检测可以通过判别当被按压而使反转板10反转的负荷变化和扣击但反转板10不反转时的负荷变化来实现。
在上述输入装置1中，预定的输入方式和另一种输入方式通过控制部21以软件方式进行处理。由此，各个输入方式自动被切换，显示屏3的显示被切换为与各自的输入方式相对应的显示上。
下面对上述输入装置1的控制部21中的处理进行说明。
如图4所示的那样，在步骤1(ST1)中，判别输入方式，即判别与在输入位置8上所显示的指示项目相对应的输入是否处于能够执行的状态。当在ST1中是预定的输入方式时(是)，移到ST2，在显示屏3上显示与输入位置8的指示项目相对应的画面。接着，移到ST3，当平面型输入装置4的输入位置8被按下时，生成根据所按下的输入位置8的指示项目的输入信号。在ST4中，根据上述输入信号生成操作信号，显示屏3的显示反映为对应于上述操作信号。
而且，当在ST1中是另一种输入方式时(否)，移到ST5，在显示屏3上显示与坐标数据的输入相对应的画面，例如，菜单选择画面和光标移动画面。接着，移到ST6，当平面型输入装置4被操作时，与输入位置8的显示无关，从上述平面型输入装置4生成输入信号。接着，移到ST7，把上述输入信号识别为坐标数据，显示屏3的显示反映为对应于坐标数据。
在上述输入装置1中，反转板10是用于向操作者提供操作触觉的单一功能的圆顶状的金属板，但是，也可以通过该反转板的反转来进行开关输入。
图5是反转板10能够进行开关输入而作为开关元件11的构成。
如图5所示，上述开关元件11是：在PET制的树脂片12的两个表面上通过印刷形成由Ag类膏组成的作为导电体的电极13a和导电图形13b的图形。
电极13a设在树脂片12的上表面，在中心形成圆形的电极13a1，在其周围隔开预定的间隔形成环状的电极13a2，在电极13a3的一部分上连续形成导电图形。在树脂片12的下表面形成导电图形13b，该导电图形13b与上述电极13a1相连接。即，在上述电极13a1的下表面的树脂片12上形成通孔，在该通孔中设置使导电图形13b与电极13a1导通的连接导体14。而且，在电极13a2上设置圆顶状(膜片状)的反转板15，设置成这样：在反转板15的周缘部接触到电极13a2的状态下，反转板15的顶点位置与上述电极13a1的位置相一致。
而且，在反转板15的周围以及上述导电图形13b的下表面上分别设置保护膜16a，16b。而且，表面全体由PET制的树脂片17所层叠，接着，在上述保护膜16b的下表面上，树脂和金属制的基座18通过粘接剂层19进行连接，而构成开关元件11。
当从上述平面型输入装置4上面通过手指进行按压操作时，平面型输入装置4和显示片7弹性变形，而且，通过该按压力来按压反转板15。由此，反转板15象图中的点划线所示的那样被反转，反转板15与电极13a1相接触。其结果，电极13a和导电图形13b导通，开关输出切换为接通。因此，在上述情况下，不管在平面型输入装置4中所生成的输入信号。并且，通过使反转板15发生反转，给操作者提供由此时的按压反作用力所产生的操作触觉。
下面参照图6和图7来说明本发明的输入装置的第二实施例。
图6所示的输入装置30是移动电话，外壳2中装载了作为显示装置的显示屏3和作为输入部分的平面型输入装置31。而且，在输入装置30中，仅平面型输入装置31的一部分是不同的，其它构成与上述输入装置1相同而省略其说明。
平面型输入装置31是感压型和静电电容型的。在静电电容型的平面型输入装置31中，与上述相同，X方向检测电极和Y方向检测电极通过在其间夹着PET(聚对苯二甲酸乙二酯)制的树脂片而相对地形成为矩阵状，形成上述电极的树脂片设在ガラエポ和金属制的具有刚性的基板上。而且，在平面型输入装置31上，在其外侧固定与上述相同的显示片7，在其里侧设置操作触觉发生装置33。
上述操作触觉发生装置33是顶端被上下可动地支撑的突起35。在设在外壳2内的凹状的基座36并且上述平面型输入装置31的里侧的中央设置一个该突起35。上述突起35构成为：当从上侧被按压时，发生按压反作用力等触觉。而且，上述操作触觉发生装置33可以由上述圆顶状的反转板等构成。
在上述平面型输入装置31和上述基座36之间设置作为升降装置的弓架34。
如图6所示的那样，通过上述弓架34来在上下方向上移动自如地支撑平面型输入装置31。
在图6的A所示的操作前的状态下，上述弓架34处于稍稍提升的状态下，平面型输入装置31与显示片7一起位于上端。此时的平面型输入装置31可以通过上述突起35的弹性力而提升，或者，通过设在基座36上的未图示的螺旋弹簧等弹性部件来提升。
因此，当从平面型输入装置31的上侧通过手指等进行按压时，弓架34折叠起来，平面型输入装置31和显示片7的全体被压下而成为水平的。其结果，突起35被压入，通过此时产生的按压反作用力等来给操作者提供操作触觉，操作者能够确实地识别按压动作。
而且，在上述输入装置30中设置与上述输入装置1相同的控制部，进行预定的输入方式和另一种输入方式的切换。而且，预定的输入方式和另一种输入方式的切换通过与上述同样的处理来执行。
本发明的输入装置并不仅限于移动电话，可以是例如：设定预定的输入方式作为电视机的遥控器用，设定另一种输入方式作为游戏机的控制器用。
