Abstract
A image reading device is activated by the light interference of a light path. The image reading device comprises at least a image sensing element, a picture and a image changing mechanism such as a picture conveying module, picture rotating module, a hole or a soft button with picture in the inner side. The user may use finger or other objects to interfere the image generated in the image sensing element. By detecting the changes of the image, a predetermined activation process of the image reading device is therefore started.
Claims40
An image reading device, comprising:
- an image sensing unit for sensing an image of a picture and generating signals;
- a first picture for producing a first analog signal by said image sensing unit;
- a second picture for producing a second analog signal by said image sensing unit;
- and
- an image switch mechanism for changing positions of said first picture and said second pictures, wherein a predetermined function is activated when said first analog signal is different from said second analog signal.
An image reading device, comprising:
- an image sensing unit for sensing an image of a picture and generating image signals;
- a picture for producing an analog signal by said image sensing unit;
- and
- an image switch mechanism for changing a position of said picture,
- wherein a predetermined function is activated when said analog signal is changed.
An image reading device, comprising:
- an image sensing unit for sensing an image of a picture and generating image signals;
- and
- a hole for producing an analog signal by said image sensing unit,
- wherein a predetermined function is activated when said analog signal is changed due to the concealed hole.
An image reading device, comprising:
- an image sensing unit for sensing an image of a picture and generating image signals;
- and
- a soft button, having a picture printed in the inner side of said soft button, for producing an analog signal by said image sensing unit,
- wherein a predetermined function is activated when said analog signal is changed.
