PROBLEM TO BE SOLVED: To make replacable a display operation device with an optional size one without degradation in performance of a mounting mechanism by the size of the replacement display operation device or without depending on the size of the display operation device installed initially. SOLUTION: This weighing device is provided with the cover mounting mechanism selectively mounting a first cover 24, which can be mounted when a horizontal dimension of the display operation device 5 installed to a casing 2 by means of the mounting mechanism is substantially equal to the dimension of a mounting part, or a second cover, which can be mounted when the horizontal dimension of the display operation device 5 mounted by the mounting mechanism is larger than the dimension of the mounting part, to the casing 2.
