Abstract
A paper-size index device and a paper-supplying cassette used with an image-forming apparatus. A paper regulator is installed to be movably set depending on sizes of sheets of paper loaded in the paper-supplying cassette, and a rotational wheel is set at a determined position while rotating by an interaction unit connected to the paper regulator, so that the paper-size information marks provided on one side thereof are exposed through a transparent window. Accordingly, paper-size display and detection operations set at the paper-supplying cassette can be interactively performed.
Claims20
A paper-size index device used with an image-forming apparatus, comprising:
- a main body;
- a paper-supplying cassette detachably mounted in the main body to receive one or more sheets of paper;
- a paper regulator movably installed to regulate and arrange the sheets of paper loaded in the paper-supplying cassette;
- a rotational wheel rotatably installed in the paper-supplying cassette, and having paper-size information marks thereon;
- a paper-size sensing unit to detect at least one of the paper-size information marks and to send paper-size information to the main body;
- and
- an interaction unit to control the rotational wheel to rotate according to a movement of the paper regulator.
A paper-supplying cassette used with an image-forming apparatus, comprising:
- a paper receptacle case detachably installed in a main body of an image-forming apparatus to receive one or more sheets of paper;
- a paper regulator movably installed to regulate and arrange the sheets of paper loaded in the paper receptacle case;
- a paper-detecting unit installed on the main body to detect paper size information of the sheets of paper;
- and
- a paper-size display unit to externally display paper-size information in interaction with the paper regulator at the same time when the paper-detecting unit detects the paper size information from the paper-size display unit.
A paper-supplying cassette used with an image-forming apparatus, comprising:
- a paper receptacle case to receive one or more sheets of paper;
- a paper regulator to regulate and arrange the sheets of paper loaded in the paper receptacle case according to a size of the sheets of paper;
- a paper-size display unit to display paper-size information;
- and
- an interaction unit disposed between the paper regulator and the paper-size display unit to control the paper-size display unit to change a position of the paper-size information according to a movement of the paper regulator.
An image-forming apparatus, comprising:
- a paper-size index device comprising:
- a paper-supplying cassette to receive one or more sheets of paper,
- a paper regulator to regulate and arrange the sheets of paper loaded in the paper-supplying cassette according to a size of the sheets of paper,
- a rotational wheel having paper-size information marks thereon, and
- an interaction unit connected between the paper regulator and the rotational wheel to control the rotational wheel to change a position of the paper-size information marks according to a movement of the paper regulator.
