<p>PURPOSE:To make positioning of a cam gear for operating modes accurate and to ensure a mode changeover operation and a decision of a mode switch and then to prevent malfunction by disposing the cam gear at the poststage side of a gear for loading. CONSTITUTION:When an inlet side guide base 55 and an outlet side guide base 56 are brought to catchers 57 and 58 on the inlet side and the outlet side respectively to be positioned, loading rings 64 and 65 are fixed, and then gears 81 and 82 to be meshed with them are also fixed. Since a loading motor 6 is to be further rotated, a torsion spring 105 is deformed, and the base 55 is pressed against the catcher 57 via the ring 64. Similar operation is performed on the ring 65 and the gear 82 for loading the base 56. Thus, by disposing the cam gear 1 at the last stage of a gear train for transmitting the rotation of the motor 6, the gear 1 is not affected by torque from the spring 105, etc. The upper surface of the gear 1 is formed with cam surfaces 87 and 88 for operating modes, while the lower surface the mode deciding switch.</p> |
