<p>PURPOSE:To shorten the working hour of belt putting work, by providing a projected rib for putting belt in the periphery of a through hole, into which a reel base is inserted and a hole closely to the rib, and then, approaching a pulley constituting the above-mentioned reel base to the rib. CONSTITUTION:A reel base 3 equipped with a pulley 2 constituting the main body section 1 of a tape driving mechanism is inserted into a through hole 4 provided with a concealed plate 7 constituting the tape driving mechanism 1 and approached to a rib 5 provided in the circumference of the through hole 4. The concealed plate 7 is provided with a small hole 6 in the vicinity of the rib 5 and, when a belt 9 temporarily put on a rib 5 is removed by means of a needle-like jig 8 inserted into the small hole 6 under a condition where the concealed plate 7 is assembled in the main body section 1, the belt 9 can be put in the groove 2a of the pulley 2. Therefore, the belt 9 can easily be put on the pulley 2 and, as a result, the operability of the belt putting work is improved and the working time can be shortened.</p> |
