解説
問 14
Incorrectア
A GPS receiver is a device that receives radio waves from multiple positioning satellites to determine the current location (latitude, longitude, etc.). It is equipment for position measurement and has nothing to do with digitizing paper documents, so it is incorrect.
- イ
正解 A scanner is an input device that shines light onto documents or drawings printed or written on paper, reads the reflected light, and converts it into image data (electronic files). As in this question, when you want to digitize past paper documents and design drawings into electronic files and share them across the entire company, a scanner that can read originals one sheet at a time and turn them into images is the most appropriate, so the correct answer is “イ”.
Incorrectウ
A digitizer is a device that inputs, as numerical data, the coordinates of a point indicated by a pen or cursor on a dedicated tablet, and is used in CAD and similar tools to capture the coordinates of figures. It is not suited to reading an entire existing paper document wholesale as an image file, so it is incorrect.
Incorrectエ
A plotter is an output device that draws drawing data inside a computer onto large-format paper with a pen or the like. It works in the direction of outputting data onto paper, opposite to the input action of digitizing paper, so it is incorrect.
ここがポイント
- Scanner = an input device that optically reads paper documents and drawings and converts them into image data (electronic files).
- Distinguish input devices (scanner, digitizer) from output devices (plotter), and choose the device used in the “paper → electronic” direction.
