Description

具标准数据接口的便携式数据转换处理装置 技术领域
本发明涉及一种具有标准数据接口的数据处理装置， 尤其是一种便携式 的、 能够方便地结合多种格式数据处理装置以及存储器的具有标准数据接口便 携式数据转换处理装置， 属于计算机外围数据处理 ΐ殳备。 背景技术
计算机原有的存储器使用磁介质来存储数据， 现在计算机上所用的软盘、 硬盘都属于磁介质存储设备。 磁介质存储设备可以很方便地做成高容量存储 器， 但是存在寿命短、 可靠性差的缺点。 而且目前移动储存设备中， 普遍存在 无法真正移动储存的目的， 大部分因为体积太大携带不方便如外置式硬盘， 外 置式刻录机， ZIP, MO...等， 这些设备能提供较大容量存储但机动性不足。 作 为便携式存储器， 例如， 软盘， 不仅专用的驱动器占用体积大， 能量消耗、 噪 音大， 而且运行速度慢， 使用中容易出现物理损坏。 随着半导体技术的发展， 非易失性固态存储器的容量越来越大， 而价格却越来越低，在这种技术环境下， 用固态存储盘替代软盘或硬盘的设计无疑会大大提高计算机的工作和数据可靠 性。 现有的固态存储盘种类繁多， 有 CF卡、 MMC卡、 SMC卡以及更多发展迅速 的是具有 USB接口的非易失性固态存储器盘。 它们通过各自的连接接口结构与 PC之间进行数据交换。
由于各种卡的结构不一， 使 PC 不得不具有各种各样的接口才能满足上述 固态存储器的连接使用， 这样不仅需要增加 PC主板不同的电气连接接口， 而 且也使 PC或其外设的结构变的复杂了。
现在各种标准数据接口技术， 例如 USB或 IEEE394等， 已经成为 PC领域 广为应用的较新型接口技术。 非易失性存储介质闪存一 FLASH半导体技术具有 较磁介质等存储材质更为优越的特点， 以及基于该介质的存储器不需要复杂的 驱动机构的特点， 该类存储器正逐步替代现有的便携式存储器设备。
另一方面， 集成电路卡由一个或多个集成电路芯片组成， 并封装成便于人 们携带的卡片； 具有暂时或永久性的数据存储能力， 其内容可供外部读取或供 内部处理、 判断； 具有逻辑和数学运算处理能力， 用于识别和响应外部提供的 信息和芯片本身的处理需求。 IC 卡作为集成电路卡， 是一种随着半导体技术 的发展和社会对信息安全性等要求的日益提高而应运而生的， 具有微处理器及 大容量存储器等的集成电路芯片且嵌装于塑料等基片上制成的卡片。 由于 IC 卡采用了当今最先进的半导体制造技术和信息安全技术， 因此 IC 卡相对于其 它种类的卡具有以下四大特点： 1、 存储容量大： 其内部有 RAM、 ROM, EEPROM 等存储器， 存储容量可以从几个字节到几兆字节。 卡上可以存储文字、 声音、 图形、 图像等各种信息。 2、 安全性高： IC 卡从硬件和软件等几个方面实施其 安全策略， 可以控制卡内不同区域的存取特性。 存储器卡本身具有安全密码， 如果试图非法对之进行数据存取则卡片自毁， 即不可进行读写。 3、 对网络要 求不高： IC 卡的安全可靠性使其在应用中对计算机网络的实时性、 敏感性要 求降低， 十分符合当前国情， 有利于在网络质量不高的环境中应用。
由于集成电路卡的可靠性及安全性， IC 卡的使用已越来越普及， 从金融 产品到个人消费产品皆可见 IC卡的踪影， 因此， 在 IC卡用量逐年增加的情形 下， PC与 IC卡的结合将成为无法避免的趋势； 同理， IC卡读卡器的需求也将 曰趋增加。 由于现有的计算机没有 IC卡读卡器的设置， 因此这样的计算机无 法使用 IC 作为其鉴别手段。 另外， 计算机本体上的通信口是有限的， 而现有 数据输入的种类、 方式的增多， 往往会出现计算机的接口被全部占用， 一些外 部设备无法与之通信， 只能轮流插入使用， 或者根本无法直接连接。
目前基于上述技术的产品有 USB存储器、 CF卡读卡器、 SMC卡读卡器、 IC 卡识别器等。 这样从产品设计和使用的角度， 没有利用共用的器件， 也没有能 够灵活地满足实际应用的变化和组合， 相对都是随任何一款产品而固定了容量 或功能， 使使用者不得不购买或使用一个个功能不能集成、 形式独立的这些消 费电子产品， 而且还不能更新和升级。 再有， 从产品的制造角度， 由于没有更 好地进行模组化结构改变， 而不能更好地降低成本、 提高产量。 另外， 由于在
PC机使用中的身份认证、 无线数据交换等需求存在， PC机上日益集成了过多 的接口和数据处理装置， 而没有更为便捷的配置。 发明内容
本发明的主要目的在于提供一种具标准数据接口的便携式数据转换处理装 置， 其建立了存储器与计算机方便、 易用的通信桥梁， 基本构成包括连接器和 数据处理器组成的本体， 保证数据的调度和传送， 并且外部功能器件或存储器 作为其外设的配件， 并且它们能够方便地从本体上拔下或装上。

再有， 本体 3上设有读写状态控制开关 7。
外部器件 4也与后盖 5为一体， 后盖 5、 外部器件 4整体与本体 3之间为 导槽滑设连接或卡接， 电气连接处 6为弹性顶触连接或插接均可， 为实现组件 之间的标准数据连接， 或组件的标准模块化设计， 直接采用标准接口连接， 例 如 USB连接接口连接， 也可釆用其他标准接口连接。
为保护连接器 1， 可在端部设计盖体 11。 还可具有读写控制开关 7。 实施例 2: 如图 4所示， 本发明数据处理器本体 3为连接器控制器 31或 带有功能处理装置的转换控制器 32分体设计构成本体 3。 转换控制器 32为多 卡转换模块或射频处理器或 IC识别处理器， 或及其相互组合的多功能处理器。 分体的转换控制器 32的一端为与处理器本体 31电气连接匹配接口， 另一端设 有与外部器件 4进行电气连接的匹配接头， 相互可以——级连。 连接接口同样 可采用标准 USB接口、 CF卡连接器或匪 C卡连接器或 SD卡连接器或 SMC卡连 接器或 IBM Micro Drive连接器或 RS-232或 COM口或 IEEE1394或 PS/2等。 实施例 3: 如图 5所示， 在该实施例中， 本发明外部器件 4从外壳上就与 本体 3完全为独立的部件， 两者之间弹性卡接， 外部器件 4外壳上设有弹性卡 扣 8 , 本体 3设有勾入部。 结合时， 弹性卡扣套入本体 3上勾入部内。 外部器 件 4与数据处理器 1对应位置电气连接处 6设有电气连接接头。 实施例 4: 如图 6所示， 本发明数据处理器本体 3为连接器控制器 31或 带有功能处理装置的转换控制器 32 分体设计构成本体 3 , 连接可与实施例 3 一致。 转换控制器 32为多卡转换模块或或射频处理器或 IC识别处理器， 或及 其相互组合的多功能处理器。 分体的转换控制器 32 ,的一端为与处理器本体 31 电气连接匹配接口， 另一端设有与外部器件 4进行电气连接的匹配接头， 相互 可以——级连。 连接接口同样可采用标准 USB接口等。 实施例 5 , 如图 7所示， 在该实施例中， 外部器件 4从外壳上就与本体 3 完全为独立的部件， 两者之间通过相互插接， 如同插座和插头的连接结构。 外 部器件 4与数据处理器 1的对应位置电气连接处 6设有电气连接接头。
