IMAGE PROCESSING DEVICE, IMAGE FORMING DEVICE AND IMAGE READER

PROBLEM TO BE SOLVED: To provide an image processing device having a sheet supply tray capable of effectively improving a force for sending a sheet into a bind-in part of a body.SOLUTION: A complex machine has the body 78, a paper carrying device, a manual feed tray 60 and the bind-in part 55. The paper carrying device is arranged in the body 78. The manual feed tray 60 is provided for setting paper 100. The bind-in part 55 is arranged at the downstream side in the paper carrying direction of the manual feed tray 60 for introducing the paper 100 set in the manual feed tray 60 into the paper carrying device. The manual feed tray 60 has a tray body 70 and a guide rib 66. The tray body 70 has a placing surface 90 for setting the paper 100. The guide rib 66 is projected on the placing surface 90 for guiding the carriage of the paper 100 from below, and formed so as to reduce a projection quantity for approaching the downstream side from the upstream side in the paper carrying direction.
