A device that changes images from either reflection or transparency medium to digital data.

Input device on a computer which converts characters or marks to machine codes. Character readers, Bar Code Reader or Mark Reader.

A device that converts printed images and text into digital information that can be stored as a computer file and processed by computer software.

A scanning device that captures typed documents, pictures, graphics, or even handwriting for use by a computer.

An electronic device for converting hard copy into digital copy, usually in the form of an image.

a device that can be passed over a printed text and which "reads" the text into a computer

A device that scans both written text and graphics and converts them into digital information suitable for electronic processing or transmission.

Often simply called a scanner, a device that reads images and text, allowing a user to input and utilise the data in various applications. A scanner digitises the image. This means it divides the entire image into tiny boxes and assigns a value to each isolated unit using 0s and 1s. Essentially, this is what a bitmap is. The scanned image, whether text or a graphic, therefore, becomes a bitmap. Consequently, the scanned data cannot be directly altered unless optical character recognition technology is used.

A hardware component that photoelectronically scans for marks such as those made by a number 2 pencil on a test answer sheet, or for characters or images such as a facsimile (FAX), or optical character recognition (OCR) device.

A device that scans optically and usually creates an analog or digital signal.

Input device that optically reads a line of printed characters and converts each character to its electronic equivalent for processing.

a device that uses light to scan and convert text, graphics or other images into digitized data that can be read by a computer.

Input device that translates human-readable or microform images to bit-mapped or rastered machine-readable data.

Light-sensing input device that reads printed text and graphics and then translates the results into a form the computer can use. Also called a scanner. 1.5, 1.36, 5.25- 27 fingerprint, 12.11
