The case body has a pair of opposed, but spaced first and second walls and an intermediate wall connecting the first and second walls to each other. The first and second walls are provided with a first pair of opposed parallel channels which are located adjacent a front opening, and a second pair of opposed parallel channels which are located adjacent a rear opening. A third pair of opposed parallel channels are provided such that a plane including a third pair of channels is located between the first and second pairs of channels. Each of a pair of display units has a display assembly of dot-matrix type mounted on a circuit board. The circuit boards of the respective display units are inserted respectively into the first and second pairs of channels. A drive unit has a drive controller mounted on a circuit board, for driving the display assemblies to cause them to effect their respective displays. The circuit board of the drive unit is inserted into the third pair of channels.
