A tape display device comprises a housing (10) supporting a pair of parallel rollers (11, 12) between which a tape (14) is adapted to be wound back and forth to display different visual information contained on the tape. The rollers are driven by a continuous belt (20) via an electric motor (17). One of the rollers is a tension roller (11) which maintains tension in the tape as it is would back and forth between the rollers. The tension roller consists of a cylinder (25) having end caps (26) for providing bearing surfaces which bear on respective bushes (27) in the housing to provide rotational mounting of the roller. A drive pinion (22) on the outside of the housing has a stub-axle (28) which extends through the bush and end cap and into the cylinder. A spiral tension spnng (29) is attached between the end of the stub axle and a flange of the end cap (26). The spring is located within the cylinder and allows relative movement between the cylinder and pinion and maintains tension in the tape as the two rollers rotate in synchronism and the diameter of the tape on each roller varies.
