Abstract: A hand-held control device comprises a casing (1) having a plurality of operating switches (21) and a cut hole (3) in front face thereof, a transparent window (5) fitted in the cut hole (3) of the casing (1), a printed circuit board (6) accommodated in the casing (1) and connected to the operating switches (21), a crystal liquid display plate (7) disposed near the window (5) of the casing (1) and connected to the printed circuit board (6) through a connector (8), the crystal liquid display plate (7) being fixed with a mounting member (10) so as to the connector (8) is sandwiched between the mounting member (10) and the printed circuit board (6), and an upper cover (17) and a lower cover (14) for holding the printed circuit board (6) through the buffer member (10). Accordingly, even when an impact is applied onto the casing (1), the liquid crystal display plate (7) is less affected thereby, and therefore the contents of display can be surely displayed on the liquid crystal display plate (7).
