Abstract
An ink jet recording apparatus is provided with a recording function to record images on a sheet material by installing an ink jet recording head that discharges ink from the ink discharge ports, and also, with an image reading function to read images from a sheet material by installing an image reading head exchangeably. This apparatus includes the discharge port surface of the ink jet recording head having the ink discharge ports formed on it, the image reading surface of the image reading head to read images to this head from the image reading surface, and a member that abuts upon the ink discharge port surface arranged to be in contact with the ink discharge port surface of the ink jet recording head. This member is arranged so as not to be in contact with the image reading surface of the image reading head. Thus the image reading surface of the image reading head is prevented from being stained by ink. Also, this apparatus can be made smaller with a simple structure to provide both reading and recording functions.
