Abstract

Abstract The invention provides an image recording apparatus with cooling fan. Namely, the apparatus comprises copying device for forming toner image and transferring the toner image on a copy sheet; a cooling fan for cooling the copying device; and control device for operating the cooling fan. The control device includes a memory for storing a reference data with respect to recording condition of the copying device, and detector for obtaining data of current recording condition of the copying device, whereby the control device compares the obtained data with the stored reference data. In accordance with this comparison, the control device operates the cooling fan.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 131 words
An image recording apparatus comprising: (a) an image recorder for forming a toner image and for transferring the toner image to a copy sheet; (b) cooling fan for cooling said image recorder; and (c) a control for controlling said cooling fan during a copying operation cycle, said control having (1) a memory for storing a reference copying operation time of said image recorder, (2) a timer for obtaining an actual copying operation time of said image recorder, and (3) a comparitor for comparing said actual time with said reference time during said copying operation cycle, said control operating said cooling fan so that, when said comparitor determines that said actual time is longer than said reference time, said cooling fan is changed from low speed to high speed during said cycle.
Claim 2
Dependent Claim 131 words
An image recording apparatus comprising: (a) an image recorder for forming a toner image and for transferring the toner image to a copy sheet; (b) cooling fan for cooling said image recorder; and (c) a control for controlling said cooling fan during a copying operation cycle, said control having (1) a memory for storing a reference copying operation time of said image recorder, (2) a timer for obtaining an actual copying operation time of said image recorder, and (3) a comparitor for comparing said actual time with said reference time during said copying operation cycle, said control operating said cooling fan so that, when said comparitor determines that said actual time is longer than said reference time, said cooling fan is changed from low speed to high speed during said cycle.
