I purchased this on Makuake, but since my PC is a Mac and it's not compatible, I haven't had a chance to use it, so I'm putting it up for sale. I believe the purchase price was around ¥15,000. ・Size: 34cm * 24.5cm * 7.5cm ・Dedicated mat size: 40 * 50mm ・Body weight: Approximately 582g (excluding mat) ・Sensor: CMOS 20 million pixels ・Scanning size: Up to A3 size ・Resolution: Up to 5256×3936px ・Interface: USB2.0 A-type connector male, DC5V ・Accessories: USB cable, shooting mat, USB with instruction manual ・Supported OS: Windows XP, 7, 8, 10 Here is the Makuake product page: https://www.makuake.com/project/portable_scanner/ You can download the new driver here: https://xgf.nu/JYCi
