1. An image reading system, comprising:
- an operation panel with which information about at least various operations is inputted; and
an angle adjustment device, comprisinga fixed portion including a fixed bracket having a burring tap,a movable portion including a movable bracket, the movable portion being rotatable to the fixed portion,a connection portion which connects said fixed portion to said movable portion,an elastic member which is arranged between said movable bracket and said fixed bracket and restricts rotational movement of said movable portion with kinetic friction generated between said movable bracket and said fixed bracket,a shaft bracket including a plurality of tooth portions, the shaft bracket being configured to sandwich the elastic member and the movable bracket by the fixed bracket by screwing into the burring tap of the fixed bracket, the plurality of tooth portions being formed on an outer circumference of a plate portion of the shaft bracket, anda restriction bracket including at least one dowel configured to fit into and engage at least one of the tooth portions, the at least one dowel being configured to discretely restrict an insertion amount of the shaft bracket according to a rotation amount of the shaft bracket when the shaft bracket is screwed into the burring tap by the at least one dowel engaging with the at least one tooth portion during rotation of the shaft bracket,wherein said elastic member has a washer shape and is configured to be inserted at a central axis of said movable portion so that one side face touches said fixed bracket and another side face touches said movable bracket, the elastic member generating kinetic friction force corresponding to an amount of elastic deformation of the elastic member when the at least one dowel engages the at least one of the tooth portions during rotation of the shaft bracket, the amount of elastic deformation of the elastic member being controlled based on a fastening force to fasten the movable bracket to the fixed bracket, the fastening force being dependent on the insertion amount of the shaft portion,and said angle adjustment device permits a position of said operation panel to be varied by a movement of said movable portion.
