Claims

[Claims for Utility Model Registration] A carriage B supporting an image sensor for reading and scanning a document A placed along the surface of a platen P along the main scanning direction a carriage drive device _D1 that reciprocates along the direction A serial type image scanner comprising a device _D2 , carriage movement signal input means _SW3 , _SW4 for operating the carriage drive device _D1 , and paper feed signal input means _SW1 for operating the paper drive means _D2 . , SW ₂ , and a carriage position detection means S _c for detecting the positions x ₁ , x ₂ of the carriage in the main scanning direction X with respect to the reference position x ₀ in the main scanning direction X from the operating amount of the carriage drive device D ₁ ; paper position detection means S y for detecting the positions y ₁ , y ₂ of the document A in the sub-scanning direction _Y with respect to the reference position y 0 in the sub-scanning direction _Y from the operating amount of the paper drive device D ₂ ; Output command means SW ₀ is provided, and this output command means SW ₀ for specifying the reading range is provided. A serial type characterized in that the detection signals of the carriage position detection means _Sc and the paper position detection means SY are outputted as a carriage position signal for specifying a reading range and a paper position signal for specifying a reading range according to an output command signal from the Image Sukiyana.
