SOLUTION: As for the driving of a 2nd thermal fixing roller 17b, a 1st fixing roller 47a is driven and rotated, a 2nd fixing roller 47b is driven and rotated through an idler gear by receiving the driving rotation of the roller 47a, then the roller 17b is driven and rotated in the state that it is held between the rollers 47b and 47a. In such a case, the roller 17b is driven and rotated by a press-contact part TN formed between the roller 47b mainly used as a soft roller. Thus, pressure is not directly applied to the rotating member for thermal fixing from a driving system and the light transmissive base substance is prevented from being broken in the case of driving the rotating member for thermal fixing.

Abstract: PURPOSE:To independently operate both motors of two cars without the number of connecting lines being inclined, by providing a receiver device for a non-contact switch in a bobbin replacing machine provided with a travelling motor and a compressor motor, and as well by providing a transmitter device for an actuator for operating a carrier car, in the latter. CONSTITUTION:When a limit switch is closed after a rail for a carrier car 4 and a guide rail 5 for a spinning and weaving machine bed 2 being coupled together, a power feed relay is energized to initiate the supply of power to a bobbin replacing machine 1. Then, when a push botton for starting the bobbin replacing machine 1 is operated under the condition that the compressed air pressure of the bobbin replacing machine 1 is maintained at a pressure higher than a set value and an air-pressure detecting switch is closed, a start instruction solenoid is energized, and therefore, a reed switch is closed to energize and as well to self-sustain an electromagnetic relay for a travelling motor. Therefore, the travelling motor is driven so that the bobbin replacing machine 1 starts from the carrier car 4, and doffing is carried out in accordance with a doffing control circuit disposed in the bobbin replacing machine 1. Even if a compressor motor switch is mistakenly operated when the air pressure exceeds a predetermined value, a travelling motor is not started since a normally-open contact is opened so that a solenoid is not energized.
