Abstract
There is described an image reading apparatus, which employs the electric double layer. The image reading apparatus includes: an electric power source; an analogue image signal generating section that is coupled to the electric power source through a power line and converts an optical image to analogue image signals; an electric double layer capacitor that is coupled to the power line; a first switch that is coupled to both the electric power source and the electric double layer capacitor, in such a manner that the first switch is inserted between them; and a controlling section to control the first switch so as to make the first switch open in response to a output request signal for requesting an outputting operation of the analogue image signals.
Claims20
An image reading apparatus, comprising:
- an electric power source;
- an analogue image signal generating section that is coupled to said electric power source through a power line and converts an optical image to analogue image signals to output said analogue image signals;
- an electric double layer capacitor that is coupled to said power line;
- a first switch that is coupled to both said electric power source and said electric double layer capacitor, in such a manner that said first switch is inserted between said electric power source and said electric double layer capacitor;
- and
- a controlling section to control said first switch so as to make said first switch open in response to a output request signal for requesting an outputting operation of said analogue image signals.
An image forming apparatus, comprising:
- an electric power source to supply a power source voltage through a power line;
- an image reading section, coupled to said power line, to read an image residing on a document so as to output image data representing said image;
- and
- an image forming section to form a reproduced image onto a recording medium, based on said image data outputted by said image reading section;
- wherein said image reading section includes:
- an analogue image signal generating section that is coupled to said electric power source through said power line and converts an optical image to analogue image signals to output said analogue image signals;
- an electric double layer capacitor that is coupled to said power line;
- a first switch that is coupled to both said electric power source and said electric double layer capacitor, in such a manner that said first switch is inserted between said electric power source and said electric double layer capacitor;
- and
- a controlling section to control said first switch so as to make said first switch open in response to a output request signal for requesting an outputting operation of said analogue image signals.
