Ink jet recording apparatus recording images when an ink jet recording head is installed thereon and reading images when an image reading head is installed thereon
First Claim
1. An ink jet recording apparatus having (i) a recording function to record images on a sheet material when an ink jet recording head discharging ink from ink discharge ports is installed on said ink jet recording apparatus, and (ii) an image reading function to read images from a sheet material when an image reading head is installed on said ink jet recording apparatus, wherein the ink jet recording head includes a discharge port surface having the ink discharge port formed thereon, and wherein the image reading head includes an image reading surface for reading images, said apparatus comprising:
- a carriage capable of mounting the ink jet recording head and the image reading head;
a head contacting member provided opposed to said carriage in a moving area of said carriage;
an image reading head positioning mechanism for positioning the image reading head on said carriage when the image reading head is installed on said ink jet recording apparatus, said mechanism positioning and mounting the image reading surface of the image reading head at a position out of contact with said head contacting member; and
a recording head positioning mechanism for positioning the ink jet recording head on said carriage when the ink jet recording head is installed on said ink jet recording apparatus, said recording head positioning mechanism positioning and mounting the recording head discharge port surface at a position contactable by said head contacting member.

Abstract
An ink jet recording apparatus is provided which is capable of performing a recording function for recording images on a sheet material when an ink jet recording head discharging ink from ink discharge ports is installed thereon and for performing an image reading function to read images from a sheet material when an image reading head is installed thereon. The ink jet recording head includes a discharge port surface having the ink discharge ports formed thereon. The image reading head includes an image reading surface for reading images. The apparatus includes a member abutting upon and arranged to be in contact with the ink discharge port surface of the ink jet recording head when the ink jet recording head is installed. The member is also arranged so as not to be in contact with the image reading surface of the image reading head when the image reading head is installed.
