Flatbedskannere

Flatbed scanners are a type of image scanner designed for scanning flat documents, such as paper, photographs, and thin films. They are typically placed horizontally and use a scanning mechanism to capture images of an object placed on their surface.

The flatbed scanner consists of a glass plate covered by a transparent cover or lid, which is designed to be lifted up or slid in and out of a slot, allowing the user to place the object to be scanned. Underneath the glass plate, there are light sources, arrays of light-sensitive photoelements (e.g. Charge-Coupled Device (CCD) or Complementary Metal-Oxide-Semiconductor (CMOS)) and motors for moving the scanning head.

Flatbed scanners are commonly used for scanning a large variety of objects including original photographs, black and white documents, color prints, and plastic cards. They use an array of light-sensitive photoelements to capture the image, and a processor to digitize and format the captured image. Modern flatbed scanners often include various features such as document scanning, film scanning, and special image enhancement algorithms.

Flatbed scanners are available in a range of sizes from compact to large and are used in both personal and commercial environments. They are preferred over drum scanners because they can scan a wider variety of materials including flat originals at higher speeds.

The scanning process involves placing the object on the scanner glass, closing the lid, and pressing the scan button. Software allows the user to crop, rotate, save and share the scanned image. Flatbed scanners often include an internal document feeder, which can scan both sides of a document in a single pass.

The style and user interface may vary depending on the manufacturer, but overall, they are typically simple to use, feature rich and relatively affordable compared to drum scanners.
