To solve a problem that an image reader requires an operating switch performing read control when the image reader is utilized while being connected directly with a portable information terminal, and a problem that the operability is bad because an operating switch having an already fixed position is utilized even when the function of a switch performing read control of the image reader is assigned to the portable information terminal.

An inexpensive image reader 1 exhibiting good operability can be provided by an arrangement wherein an operator can freely and arbitrarily alter the position, the size, and the contact time for making control to function on an image display touch panel 9 with regard to an operation control icon 11 for controlling the read operation of the image reader 1.
