Abstract
An image input device of a portable type includes a light source for reading an original document, a photo-electric converting element for converting reflected light from the original document into an electrical signal, a memory function section having a solid state memory element for storing the output of the photo-electric converting element, an output port for allowing external connections, and operating keys for operating the image input device. Furthermore, the image input device may include a diffraction grating for diffracting the reflected light to form an image on the photo-electric converting element and interchangeable lenses having different focal lengths for achieving various magnifications.
Claims14
An image input device of a portable type, comprising:
- a light source for emitting light onto an information medium;
- image forming optical means for collecting said light emitted by said light source when reflected from said information medium and directing said light reflected from said information medium;
- photo-electric converting means for developing an image signal representative of an image on said information medium as reflected by said light and directed by said image forming optical means;
- a memory function section having a solid state memory element for storing said image signal from said photo-electric converting means;
- an output port for removably connecting external devices with said memory function section;
- and
- operating keys for operating said image input device;
- said image forming optical means having a portion for receiving interchangeable lenses by removably attaching and detaching said lenses to said portion.
An image input device of a portable type, comprising:
- a light source for emitting light onto an original document;
- photo-electric converting means for developing an electrical signal representative of an image on said original document as reflected by said light from said original document;
- exchangeable memory means for storing said electrical signal from said photo-electric converting means;
- an output port for removably connecting an external device with said exchangeable memory means;
- and
- operating keys for operating said image input device.
An image input device of a portable type, comprising:
- a light source for emitting light towards an information medium;
- image forming optical means for converging said light onto said information medium and directing said light reflected from said information medium;
- photo-electric converting means for developing an image signal representative of an image on said information medium as reflected by said light from said image forming optical means;
- exchangeable memory means for storing said image signal from said photo-electric converting means;
- an output port for removably connecting external devices with said exchangeable memory means;
- and
- operating keys for operating said image input device.
