here is your answer :-)
let's first talk about what is scanner?
A scanner is an electronic device.
It scans printed or handwritten text documents, images, or certain objects, and converts them into a digital file format.
The common types of scanners are flatbed scanners, handheld scanners, and sheetfed scanners.
1. Sheetfed Scanner
It includes the sheet-feeder, scanning module, and calibration sheet.
While the sensor and source of light move across the glass pane in flatbed scanners, in sheetfed scanners, they are stationary.
Instead, the document moves through the scanner.
Ideal for scanning single page documents,
These scanners cannot scan thick objects, like books, and that, perhaps, is their major drawback.
2. Handheld Scanner
A handheld scanner is a small manual scanning device.
It moves over the object that needs to be scanned.
In flatback and sheetfed scanners, you put the document that is to be scanned inside the device.
One of the most-utilized handheld scanner is the barcode scanner
It is typically used in shopping stores
It is used to valuate goods.
3. Drum Scanner
A drum scanner is the one which uses a photomultiplier tube (PMT) to scan images instead of the charge-coupled device that is typically used in a flatbed scanner.
Photomultiplier tubes are vacuum tubes.
Thess are extremely sensitive to light.
In drum scanners, the image is mounted on the glass tube.
Drum scanners are known for their high resolution.
It makes them apt for detailed scans.
4. Photo Scanner
As the name itself suggests, a photo scanner is mostly used to scan photographs.
It boasts of high resolution and color depth, both of which are necessary for scanning photographs.
flatbed scanners can also scan your photographs for you.
they are not as fast as dedicated photo scanners.
5. Film Scanner
A film scanner is utilized to scan photographic films directly into a computer .
Some film scanners available today have specialized software through which it is possible to minimize scratches and improve color quality.
Low-end film scanners most often accept 35 mm film strips.
high-end scanners―armed with interchangeable film loaders―can accept 35 mm or 120 mm strips and even individual slides.
