Description

传真机的DTMF传输及其显示方法
本发明涉及传真机的DTMF(双音多频)传输及其显示方法，更具体地说，涉及传真机接上电源且其收发话装置处于摘机状态时收到的电话号码的传输及其显示方法。
本专利申请是韩国专利申请NO.40224/1995提出的，这里也把该专利申请包括进来，以供参考。
通常，传真机的控制器收到的键入数据是在传真机加上驱动工作电源且电话机的收发话装置处于摘机状态的情况下输出的。提供给控制器的键入数据再由调制解调器转换成DTMF信号并将其通过电话线路传输出去。
参看图1，它是一般传真机的方框图。控制器10根据既定程序和其它操作控制传真机的整个操作，将调制解调器12输入来的DTMF信号存入控制器的缓存器中或在显示器18上显示出来。
调制解调器12调制/解调输入/输出到控制器10的信号，并将通过电话线路收到的DTMF信号传送给控制器10。
扫描器14扫描文件并将其图像数据转换成二进制码信息再将其加到控制器10上。
控制器10的操作程序和控制程序由一个存储器16控制。
显示器18由控制器10控制，显示DTMF信号相应的电话号码。
操作板20有一套键钮，操作板20是通过键钮的输入提供键入数据的。
NCU(网络控制单元)22在控制器10的控制下将电话线路与调制解调器12或电话机24连接起来。
电话机24将收自操作板20的数字键入数据转换成DTMF信号，再通过NCU22传送到电话线路。
调制解调器在上述传输DTMF的过程中，DTMF传输音不是通过电话机的收话器而是通过传真机的扬声器产生的，因而使环境的噪声大。
此外，一般的传真机有这样的问题：每次传输DTMF时，继电器要切换到调制解调器侧，这一切换产生继电器驱动声，而且继电器的继电持续时间变短。
本发明的目的是提供一种在传真机接上电源且并联连接的电话机处于摘机状态时在电话机的拨号部分进行拨号的方法。
本发明的另一个目的是提供一种显示从并联连接的电话机的拨号部分传送来的DTMF信号的方法。
本发明还有一个目的，即提供一种通过在电话机的拨号部分拨号给电话机的收话器产生DTMF传输音的方法。
本发明的传真机DTMF传输方法包括：操作板，供通过数字键的操作产生键入数据用；电话机的拨号部分，供接收来自操作板的数字键入数据并产生DTMF信号；和调制解调器，供检测收自拨号部分的DTMF信号；所述电话机和传真机并联使用；所述传真机DTMF传输方法包括下列步骤：在传真机接上驱动工作电源且电话机处于摘机状态的情况下用调制解调器检测收自拨号部分的DTMF信号；在检测DTMF的过程中显示出检测到的DTMF信号相应的电话号码；和在检测DTMF信号的过程中存储检测出的DTMF信号相应的电话号码。
图1是一般传真机的方框图。
图2是本发明DTMF传输及其显示过程的电路图。
图3是本发明DTMF传输及其显示过程的控制流程图。
图4示出了一般键入部分的键钮结构。
参看图2，这是本发明DTMF传输及其显示过程的电路图。电话机24接继电器26的第一输入端a1和a2，传真机接第二输入端b1和b2。通过传真机收发文件时，继电器26转接到接传真机的第二输入端。
第一变压器28接继电器26的第二输入端b1和b2，以便将图像数据输入/输出给传真机。
第二变压器30接继电器26的第一输入端a1和a2，以便将收自电话机的DTMF信号通过电话线路传送给调制解调器12。
电话机24中设有通话电路32，与继电器26的第一输入端a1和a2连接。通话电路32还将收自拨号部分34的DTMF信号传送给电话线路。
拨号部分34设在电话机24内，产生操作板20操作产生的数字键入数据相应的DTMF信号。
操作板20有一套数字键钮，经按压可以产生数字键入数据提供给拨号部分34的控制器10。若电话机的收发话器36处于摘机状态，控制器10就不理会操作板20提供的数字键入数据，而将经调制解调器12提供的DTMF信号视为数字键入数据。
收发话装置36设在电话机24内，供根据DTMF信号通过收话器产生DTMF传输音。
图3是本发明DTMF传输和显示方法的流程图，该方法包括下列步骤：传真机接上驱动工作电源且电话机处于摘机状态时用调制解调器检测DTMF信号；DTMF信号通过调制解调器输入时显示检测出的DTMF信号相应的电话号码；和存储检测出的DTMF信号相应的电话号码。
图4示出了一般操作板的键钮结构，其中一个键钮的四个触点有两个接控制器10，其余则接电话机24的拨号部分34。
现在参看图3连同图1和图2说明本发明的一个最佳实施例。
控制器10在图3的步骤40检测电话机24的收发话装置36是否处于摘机状态且传真机是否接上驱动工作电源。若收发话装置36处于摘机状态，控制器10就往前进入步骤42检测是否通过调制解调器12收到电话号码相应的DTMF信号。
现在说明DTMF的检测过程：操作板20通过图4中所示的触点52给电话机的拨号部分24和控制器10输出被按压的各键钮相应的键入数据。控制器10不理会收自操作板20的键入数据。拨号部分34产生操作板20输入来的键入数据相应的DTMF信号。输出的DTMF信号通过电话机的通话电路32传送给电话线路。此外，设在电话机24内收发话装置36的收话器还在DTMF信号发送过程中产生DTMF传输音，这时，通过电话线路传输的DTMF信号通过第二变压器30提供给调制解调器12。
若在步骤42检测出来自调制解调器12的DTMF信号，控制器10就在步骤44在显示器18上显示出输入的DTMF信号相应的电话号码。此外，控制器10还在步骤46将显示在显示器18上的电话号码存入设在其中的缓存器中。
综上所述，用户在收发话装置被提起且传真机接上驱动工作电源的情况下输入数字键钮时，电话机履行所述数字键钮相应的拨号功能因此，DTMF传输音总是通过收发话装置产生的。
此外，继电器由于无需经常切换因而不仅延长了其使用寿命而且其驱动噪声也得以消除。另外，由于传输的DTMF信号是通过调制解调器提供给控制器的，因而本发明使用户可以确认呼叫电话号码。
因此，不言而喻，本发明并不局限于这里作为本发明的最佳实施例公开的具体实施例，更切确地说，本发明不局限于本说明书所述的具体实施例，但下面权利要求书中所述的例外。
