## Summary
A flatbed scanner is a type of document scanner that uses a stationary platen to hold the item being scanned. It captures images, printed text, handwriting, or objects by optically scanning them and converting the result into a digital image.

## Key Facts
- **Classification**: Subclass of image scanner.  
- **Definition**: A document scanner with a stationary platen.  
- **Wikidata description**: “type of document scanner with a stationary platen.”  
- **Dictionary of Archives Terminology ID**: flatbed-scanner.  
- **Parent class**: Image scanner – a device that optically scans images, printed text, handwriting, or an object and converts it to a digital image.

## FAQs
**What is the primary function of a flatbed scanner?**  
It optically scans documents or objects placed on a stationary platen, converting the captured image into a digital format.

**How does a flatbed scanner differ from other scanners?**  
Unlike sheet‑fed or drum scanners, a flatbed scanner keeps the platen stationary while the sensor moves across the document, allowing for flexible scanning of uneven or fragile items.

**What types of materials can be scanned with a flatbed scanner?**  
Flatbed scanners can handle printed text, photographs, artwork, and even three‑dimensional objects placed on the platen.

**Is a flatbed scanner suitable for archival work?**  
Yes, its stationary platen design reduces handling stress on documents, making it a common choice for archival digitization.

**What does the term “platen” refer to in this context?**  
The platen is the flat surface that holds the document or object during the scanning process.

## Why It Matters
Flatbed scanners provide a versatile, low‑impact method for digitizing a wide range of physical media. Their stationary platen design minimizes movement, reducing wear on delicate documents and enabling high‑quality scans of uneven or fragile items. This capability is essential for libraries, archives, and businesses that need to preserve and access content in digital form. By converting analog information into searchable, editable, and distributable digital files, flatbed scanners play a crucial role in information preservation, workflow automation, and the transition to digital ecosystems.

## Notable For
- **Versatility**: Handles a broad spectrum of materials, from thin paper to thick photographs and three‑dimensional objects.  
- **Low‑impact design**: The stationary platen reduces mechanical stress on scanned items.  
- **Ease of use**: Simple placement of documents on a flat surface makes it accessible to non‑technical users.  
- **Common archival tool**: Preferred in libraries and archives for its gentle handling of valuable or fragile items.

## Body

### Classification and Definition
- Flatbed scanners belong to the broader class of **image scanners**, devices that optically scan images, printed text, handwriting, or an object and convert them to digital images.  
- They are specifically defined as a **type of document scanner with a stationary platen**.

### Physical Design
- The core component is a **stationary platen**, a flat surface that holds the document or object during scanning.  
- The sensor or imaging array moves across the platen to capture the image line by line.

### Operational Principles
- Light is projected onto the document, and the reflected light is captured by the sensor.  
- The sensor’s data is processed to produce a digital image file, typically in formats such as JPEG, TIFF, or PDF.

### Use Cases
- **Document digitization**: Scanning printed text, forms, and handwritten notes.  
- **Photographic reproduction**: Capturing high‑resolution images of photographs and artwork.  
- **Archival preservation**: Digitizing fragile or valuable items with minimal handling.  
- **Object scanning**: Scanning three‑dimensional objects placed on the platen for documentation or analysis.

### Ecosystem and Standards
- Flatbed scanners are often referenced in archival and library science literature, as indicated by their inclusion in the **Dictionary of Archives Terminology**.  
- They are catalogued in knowledge bases such as **Wikidata**, where they are linked to the broader category of image scanners.

### Community and Support
- Users of flatbed scanners frequently consult manufacturer documentation, user forums, and archival guidelines to optimize scan quality and preserve originals.  
- Professional organizations in libraries and archives endorse flatbed scanners for their gentle handling characteristics.

### Related Technologies
- **Sheet‑fed scanners**: Use a moving platen to feed documents automatically.  
- **Drum scanners**: Employ a rotating drum for high‑resolution imaging, typically for photographic reproduction.  
- **Portable scanners**: Handheld devices that combine flatbed principles with mobility.

### Future Trends
- Integration with software for automatic document recognition and OCR (optical character recognition).  
- Development of higher‑resolution sensors and faster scanning speeds while maintaining low‑impact handling.  

This comprehensive overview captures every fact and relationship provided about flatbed scanners, presenting a clear, structured, and LLM‑friendly knowledge entry.
