Inventor: TAKAHASHI HIDEYUKI
IPC: G09F9/33
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To always detect faults to be exerted on plural LEDs by calculating the target value of a supply current based on the number of LED elements to which lighting commands are outputted and outputting a failure signal when the detected value of the supply current is deviated from the target value. SOLUTION: Electric power is supplied from a power source part 3 to LED elements in lighting on a display surface and the value Ia of a supply current to be supplied at that time is detected in a current detecting part 4. A display control part 5 produces information such as character, graphic data and so forth to be displayed on the display surface 1 and outputs lighting commands or unlighting commands to LED elements in accordance with the display data. Then, the detected value Ia of the supply current is inputted to the display control part 5, which calculates the target value Ir of the supply current of the display surface 1 based on the number of the LED elements to which the lighting commands are outputted and outputs a failure signal A when the the value Ia of the supply current detected in the current detecting part 4 is deviated from the target value Ir of the supply current.

Title: Cooling device for optical system in image forming device
Inventor: SONODA SADAHIDE
IPC: G03G15/043
Filed: 1994-08-18
Abstract: PURPOSE: To make an appropriate cooling of the optical system if necessary in the image forming device by the use of a simple mechanism by driving a cooling fan when the value of impressed input voltage exceeds a specified threshold value. CONSTITUTION: When the copy start key is depressed to execute the image forming process, the same voltage to be impressed onto the illumination lamp 13 as the voltage V set in the power source 29 is inputted from the light source control device 28 to the control means 30. The control means 30 compares the preset threshold voltage value v with the input voltage. When V<v, the illuminous energy of the illumination lamp 13 is comparatively small and the amount of generated heat is also small. Hence, copy operation is started with the cooling fans, 13, 14 left at the off state positions. When V>=v, the luminous energy of the illumination lamp 13 and also heat generation are large. The control means 30, therefore, drives the cooling fans 31, 32 and starts copy operation.
