Scanners are input devices that convert physical documents, such as photographs, text, and drawings, into digital images that can be stored and manipulated on a computer. They work by using a light to shine on a document and a sensor to capture the light that bounces back. The sensor converts the light into a digital signal, which is then stored on the computer. Scanners are a versatile tool that can be used for a variety of tasks. They are a valuable asset for businesses, schools, and individuals alike.
Flatbed scanners are the most common type of scanner and are used to scan a variety of documents, including photos, text, and drawings. Flatbed scanners work by placing the document on a flat glass surface and moving a light source and sensor across it. The sensor captures the reflected light and converts it into a digital image.
Flatbed scanners are versatile and
can scan many different types and sizes of documents.They are also relatively
affordable, making them a good choice for home and office use.
Sheet-fed scanners are designed to
scan individual sheets of paper quickly and efficiently. They work by feeding
the document into the scanner one sheet at a time. The scanner then moves the
document past a light source and sensor, which captures the reflected light and
converts it into a digital image.
Sheet-fed scanners are ideal for
scanning large volumes of documents, such as invoices, receipts, and contracts.
They are also relatively compact and portable, making them a good choice for
office use.
Portable scanners are small and
lightweight, making them ideal for scanning documents on the go. Portable
scanners typically use a CCD or CIS sensor to capture the reflected light from
the document.
Portable scanners are less expensive
than flatbed scanners, but they also offer lower image quality and scan speed.
Portable scanners are a good choice for users who need to scan documents on the
go, such as sales representatives and insurance adjusters.
