| 摘要 |
An automatic rolled-paper dispenser is disclosed which utilizes one single rotor (14) for causing motions of two driving rollers (6 and 11) via a kinematic chain. The kinematic chain includes a driving pinion (15) meshing with a driven wheel (16) which in turn meshes with an orthogonal pair (17, 18) to drive a shaft (19) therethrough. The shaft (19) is provided with two helices or screws (20 and 21) driving respective gear wheels (22 and 23) carried by the driving rollers (11,6) respectively, the screw (20) being keyed on the shaft (19) while the screw (21) is secured thereto so as to be driven in rotation only for a given sense of rotation of the shaft (19). FIG. 4 Is proposed for publication with the abstract. |
