Claims
- 1. An original exposing device comprising:
- a document table;
- detecting means for detecting an exchange of a first original with a second original on the document table;
- exposing means for exposing originals in various exposing degrees which include a standard exposing degree;
- applying means for applying one of the exposing degrees to the exposing means for the first original; and
- controlling means for cancelling the applied exposing degree for the first original and setting the standard exposing degree for the second original in response to the detected exchange when the applied exposing degree is different from the standard exposing degree.
- 2. An original exposing device as claimed in claim 1, wherein the standard exposing degree is the central degree of various exposing degrees.
- 3. An original exposing device comprising:
- a document table;
- detecting means for detecting an exchange of a first original with a second original on the document table;
- exposing means for exposing the originals in various exposing degrees of a variable range;
- selecting means for selecting one of the exposing degrees for the exposing means within the variable range;
- applying means for applying one of the exposing degrees to the exposing means for the first original; and
- controlling means for changing the selected exposing degree for the first original to the standard exposing degree in response to the detected exchange when the selected exposing degree is different from the standard exposing degree and for shifting the variable range of the exposing degree to be selected by the selecting means to a predetermined variable range which includes the standard exposing degree.
- 4. An original exposing device comprising:
- a table;
- detecting means for detecting an exchange of a first original with a second original on the document table;
- exposing means for exposing originals in various exposing degrees which include a standard exposing degree;
- applying means for applying one of the exposing degrees to the exposing means for the first original; and
- controlling means for cancelling the applied exposing degree for the first original and setting the standard exposing degree for the second original in response to the detected exchange in case that the applied exposing degree is different from the standard exposing degree, and keeping the applied exposing degree for the first original irrespective of the detected exchange in case that the applied exposing degree is same as the standard degree.
- 5. A new original exposing device comprising:
- a document table;
- means for detecting an exchanging of a first original with a second original on the document table;
- exposing means for exposing originals on the document table in various exposing degrees which include a standard exposing degree;
- applying means for applying one of said various exposing degrees to said exposing means for the first original; and
- controlling means for changing the applied exposing degree for the first original with the standard exposing degree in response to the detected exchange when the applied exposing degree is different from said standard degree.
- 6. An original exposing device comprising:
- a document table;
- means for detecting an exchanging of a first original with a second original on the document table;
- exposing means for exposing originals on said document table in various exposing degrees which include a standard exposing degree;
- applying means for applying one of exposing degrees to the exposing means for the first original; and
- controlling means for changing the applied exposing degree for the first original with the standard exposing degree in response to the detected exchange when the applied exposing degree is different from the standard degree, and keeping the selected exposing degree for said first original irrespective of the detected exchange when the applied exposing degree is same as the standard degree.
- 7. In an original exposing device exposing a document supported on a document table with one of plural exposing degrees which include a standard exposing degree, the method comprising the steps of:
- selecting one of the exposing degrees;
- exposing the document with the selected exposing degree;
- detecting the exchange of an original on the document table; and
- canceling the selected exposing degree and selecting the standard degree in response to the detection when the selected exposing degree is different from the standard exposing degree.
- 8. A method of exposing a document on a document table with one of a plurality of exposure degrees which include a standard exposing degree of an exposing means comprising the steps of:
- applying one of the exposing degrees to the exposing means for a first original on the document table;
- detecting an exchange of a first original with a second original on the document table; and
- resetting, in response to the exchange, the applied exposing degree for the first document to the standard exposing degree for the second document when the applied exposing degree is different from the standard exposing degree.
- 9. A method of exposing a document on an original table with one of a plurality of exposure degrees of a variable range to be supplied to an exposing means, said method comprising the steps of:
- applying one of the exposing degrees of a variable range to the exposing means for a first original on the document table;
- selecting one of the exposing degrees to the exposing means within the variable range;
- detecting an exchange of a first original with a second original on the document table;
- resetting, in response to the exchange, the applied exposing degree for the first original to a standard exposing degree for the second original in case that the applied exposing degree is different from the standard exposing degree; and
- shifting the variable range of the exposing degree to be selected by the selecting means to a predetermined variable range which includes the standard exposing degree.
