A table made of a planar member has a suction groove for sucking and holding a recording medium on a surface thereof. A part of the sucking groove is perforated to form a suction hole. The suction hole is connected to a vacuum pump. The table includes three position determining pins that are in contact with two mutually orthogonal sides of a recording medium. The position determining pins are configured to ascend and descend by driving of an air cylinder between a descending position in which an upper end of the position determining pins is lower than a surface of the table and a position determining position in which the upper end of the position determining pins is higher than the surface of the recording medium mounted on the table. It is therefore made possible to provide an image recording apparatus capable of executing highly accurate image recording by preventing deformation of the recording medium.
