To provide a conference device having a convenient operation unit.

An operation panel 36 has a plurality of frequently used operation members aligned in an X-axis direction, and a plurality of less frequently used operation members other than the frequently used operation members aligned in a Y-axis direction together with one of the plurality of frequently used operation members. This allows a user to easily know a positional relation between the plurality of frequently used operation members and the plurality of less frequently used operation members. Thus, a conference device having a convenient operation unit can be achieved.
