Filed: 1992-08-28
Abstract: PURPOSE:To restrain dew condensation on the metallic shaft of an ejecting roller and to prevent the quality of recording paper and an image from being deteriorated by water droplet caused by the dew condensation by providing a partition member isolating the ejecting roller from a heating roller at least within the width of the recording paper. CONSTITUTION:When the recording paper P passes in contact with the heating roller 2, moisture contained in the recording paper P heated by the roller 2 is vaporized. Therefore, the amount of vapor is increased inside a frame 1 and a protective cover 11. The ejecting roller 7 is isolated from the roller 2 inside the cover 11 by the partition member 12. Therefore, even though air containing the vapor inside the cover 11 tries to flow to the roller 7 side, it butts against the member 12 and is prevented from flowing to a part where the roller 7 exists, then the air containing the vapor is guided by the wall surface of the member 12 and rises to be exhausted to the outside from an air hole 13 formed at the upper surface part of the cover 11. Therefore, the dew condensation on the metallic shaft 8 of the roller 7 is restrained.

Title: Control circuit for cooler device
Inventor: MATSUO YOICHI
IPC: G05D23/19
Filed: 1990-08-31
Abstract: PURPOSE:To perform a positive sensing of an abnormal state of a cooler device by a method wherein an abnormal signal is reset only when an output of a timer circuit energized by a variation of state change of only one direction of a reset switch and varying an output level for a specified period of time and a condition of reset signal of the reset switch are established together. CONSTITUTION:Abnormal states of a heat generating device 1 and a cooler device 5 are detected by sensors 14 to 17. When sensing signals of the sensors 14 to 17 are generated by a main control circuit of a control part 20, the cooler device 5 is stopped to protect the cooler device 5. When the abnormal state is released by a reset circuit, the control signal is returned to its normal state. A state of a switch 21 capable of operating the reset circuit from outside is inputted into the main control circuit through a reset input circuit 22. As an output level is varied in response to a variation of the state in one direction of the switch 21, its level is kept by a timer circuit 31 for a predetermined period of time and then it is inputted to the main control circuit. The resetting operation is carried out only when the conditions of the output signals of the reset input circuit 22 and the timer circuit 31 are established. Accordingly, even if the switch 21 or the reset input circuit 22 is troubled, the abnormal state of the device can be positively detected.
