Compact IGCHOW document scanner, easy to use with USB connection. Purchased on Amazon (approx. 35,000 yen) and taken out of the box and stored. When I tried to use it, it was not compatible with Mac, so I have never used it. I plan to ship it in the box of a different model scanner (images 3 and 4). - Brand: IGCHOW Scanner Type: Document, Book Brand: iOCHOW Connectivity Technology: USB Product Dimensions: 7.5 depth x 8.5 width x 37 height cm Resolution: 3200 dpi About this product: 【Powerful Features】Automatically trims to remove unnecessary parts from the image.
