    • A magnifying device for magnifying an object and displaying the object on a monitor is disclosed. The magnifying device includes a hand held unit and a base unit. The hand held unit includes a solid state camera which is mounted in a housing. The housing is supported above the text to be enlarged by a set of legs having rollers extending therebetween, to allow the hand held unit to be easily and smoothly moved across the text. The hand unit includes a focusing control and a zoom control. The focusing and zoom controls are interconnected so that the image will not have to be refocused if the magnification of the image is changed. The camera converts the image to an electrical signal which is sent to the base unit. The base unit includes inverting circuitry to convert the image from black on white to white on black, if desired. The base unit can be connected either to video monitor or a standard television. When connected to the television, the devise will not impair normal use of the television when the unit is turned off. All controls for the device are located on the hand unit to be easily accessible at all times.
    • 公开了一种用于放大对象​​并在监视器上显示对象的放大装置。 放大装置包括手持单元和基座单元。 手持单元包括安装在壳体中的固态照相机。 外壳被支撑在文本上方,以便通过一组在其间延伸的辊的腿来扩大,以允许手持单元容易且平滑地移动穿过文本。 手单元包括聚焦控制和变焦控制。 对焦和变焦控制是相互连接的,因此如果图像的放大倍数发生变化,图像就不必重新聚焦。 相机将图像转换为发送到基本单元的电信号。 基本单元包括反相电路,如果需要,将图像从黑色黑色转换为黑色。 基本单元可以连接到视频监视器或标准电视机。 当连接到电视机时,设备关闭时不会损害电视机的正常使用。 设备的所有控件位于手持单元上,以便随时可以轻松访问。

    • A scanner for reading characters from a string of characters recorded on a substrate. The scanner includes a character scanner that is used with a stroking motion parallel to the string of characters that permits the user to view the line being scanned as the scanner is moved across the page. A line-by-line scanner with a wide area of view may be mounted along the side of the scanner to be used in scanning a page or column on a line-by-line basis. The character scanner may include a lens of variable magnification so as to accommodate variable size print. A microphone mounted on the scanner permits the input of voice sound information. The scanner may be in communication with a computer through a cable or a wireless transmitter/receiver. The value of each pixel detected by the scanner is determined by comparing the light reflection value with a threshold that is adjusted in accordance with the values of pixels detected and averaged over previous frames. The hand-held scanner may be housed in any elongate housing for pen-like use or in a palm-held housing such as a typical mouse. An image splitter may be included within the optics to generate two separate images for separate character recognition processing.
    • 用于从记录在基板上的一串字符读取字符的扫描器。 该扫描仪包括一个字符扫描器,该扫描器与平行于字符串的抚摸运动一起使用,允许用户在扫描器跨页移动时查看被扫描的行。 可以沿着扫描仪的侧面安装具有宽视角的逐行扫描仪,以逐行扫描页面或列。 字符扫描器可以包括可变放大倍率的透镜,以便适应可变尺寸的打印。 安装在扫描仪上的麦克风允许输入声音信息。 扫描器可以通过电缆或无线发射器/接收器与计算机通信。 通过将光反射值与根据在先前帧检测和平均的像素的值进行调整的阈值进行比较来确定由扫描仪检测的每个像素的值。 手持式扫描器可以容纳在用于笔状使用的任何细长壳体中或者在诸如典型鼠标的手掌保持壳体中。 图像分离器可以包括在光学器件内以产生用于单独的字符识别处理的两个单独的图像。

    • A portable facsimile machine used with various power sources, including an AC power source, a car battery power source and a rechargeable battery power source, has an improved operability. The portable facsimile machine comprises a main body performing a facsimile function and a power source adaptor provided separately from the main body. The power source adaptor is adapted for use with one of the various power sources. The portable facsimile machine is further provided with an attaching mechanism for detachably attaching the power source adaptor to the main body. The contact terminals of the power source adaptor automatically make contact with the contact terminals of the main body when the power source adaptor is attached to the main body by means of the attaching mechanism. Further, a portable facsimile machine comprises a main body performing a facsimile function and a scanning unit provided on the main body which can be either in a position where the scanning unit is attached to the main body or in a position where the scanning unit is separated from the main body. The portable facsimile machine is provided with attaching mechanism for detachably attaching the scanning unit to the main body.
    • 与包括AC电源,汽车电池电源和可充电电池电源的各种电源一起使用的便携式传真机具有改进的可操作性。 便携式传真机包括执行传真功能的主体和与主体分开设置的电源适配器。 电源适配器适用于各种电源之一。 便携式传真机还设置有用于将电源适配器可拆卸地附接到主体的附接机构。 当电源适配器通过附接机构安装到主体时,电源适配器的接触端子自动与主体的接触端子接触。 此外,便携式传真机包括执行传真功能的主体和设置在主体上的扫描单元,扫描单元可以处于扫描单元附接到主体的位置或扫描单元分离的位置 从主体。 便携式传真机设置有用于将扫描单元可拆卸地附接到主体的附接机构。
