【発明の詳細な説明】
本発明はノンインパクト・プリンタあるいは複写機等の
熱圧定着器に関し、特に熱圧定着器の熱効率の改善にを
与する熱回収器の構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat pressure fixing device such as a non-impact printer or a copying machine, and more particularly to a structure of a heat recovery device that improves the thermal efficiency of the heat pressure fixing device.

る欠点があった。Conventionally, this glazed thermopressure fixing device has a fixing roller 1 coated with synthetic resin and a back-up roller 2 made of heat-resistant rubber in full pressure contact, as shown in FIG. 1, and a heater 3 inside the fixing roller 1. By applying heat and pressure to the paper 4 while rotating the two rollers, the toner was melted and fixed, but A4 size paper was heated at a rate of 10 per minute.
There was a drawback that it consumed 1 to 2 KW (D power) when ~20 sheets were fixed.
本発明は定着器の用紙出口側で出て１１＜定着済み用紙

減少させるようにした熱回収器を提供するものである。The present invention reduces the weight consumption by absorbing all the heat of the fixed paper exiting the paper exit side of the fuser, and radiating and conducting that heat to the incoming cold unfixed paper on the paper exit side. The present invention provides a heat recovery device designed to

ヒート・パイプ等の伝熱手段で結び付けている。In the heat recovery device of the present invention, a heat absorber or a heat absorbing roller is provided on the paper outlet side of the device, and a heat radiator or heat dissipating roller is provided on the paper inlet side. It is connected by heat means.
本発明の一実施例を示した図面を参照して、本発明の詳
細な説明する。The present invention will be described in detail with reference to the drawings showing one embodiment of the present invention.

and two heat absorbing rollers 6 on the paper exit side],
The heat transfer tube 5 passing through this heat absorption roller 6 and the back 11 of the drawing
411 and includes a heat dissipation roller 7 that wraps around the other end of the heat transfer tube 5 parallel to the critical roller 1 on the paper inlet side, and a heat radiator 8 that similarly wraps the other end of the heat transfer tube 5.

ローラー６を介してヒートパイプの伝熱管５に伝える。As a result, the paper 4 is sent over the heat dissipation roller 7,
It is heated and pressurized by the constant current roller 1 and the up roller 2, and reaches the endothermic roller 6. (Heated by 140-170°OV by fixing roller 1)
The heat exchanger passes between the heat absorbing rollers 6 and transmits a part of the heat to the heat transfer tube 5 of the heat pipe via the heat absorbing rollers 6.

。Furthermore, the heat transfer tube 5 transmits heat to the radiator 8i and the heat radiating roller 7, which preheat the paper 4 to be sent next by radiation, conduction, and convection. Instead of the heat absorbing roller 60, it is also possible to use a heat radiator with a heat radiator configuration of 2 heat radiators and 8 heat radiators.

する効果がある。As explained above, the present invention provides a heat absorber and a heat radiator at the paper outlet and paper inlet of a constant shield, and connects them with a heat transfer tube, thereby reducing the total amount of power consumed by the constant. It has the effect of reducing the width.
