Abstract
An image reading apparatus is activated when continuous documents are stacked on a table so that the table is raised. The table stops being raised when the upper most sheet of the documents contacts a pick-up roller. After the pick-up roller is driven and starts sending out the documents, the documents are transmitted to a discharging outlet after undergoing a readout process. When the document arrives at a given location in the apparatus, the table is lowered so that the continuous documents can avoid being damaged.
Claims3
An image reading apparatus comprising:
- a table on which documents are stacked, said table being moveable up and down;
- table moving means for raising and lowering said table;
- control means for controlling said table moving means responsive to a type of a document on said table;
- transmission means for transmitting the document fed from said table;
- and
- detection means for detecting an arrival of the document at a predetermined location in said image reading apparatus,
- wherein said control means controls said table moving means so that after raising said table, said table moving means lowers said table when the document is a continuous document and said control means also controls said table moving means to lower said table in response to an output from said detection means.
An image reading apparatus comprising:
- a table on which a document is stacked;
- a pick-up roller operable to send out an uppermost sheet of the document stacked on said table;
- table moving means for raising said table such that the document is in contact with said pick-up roller, and for lowering said table to release the contact between the document and said pick-up roller;
- document transmission means for transmitting the document sent out by said pick-up roller;
- and
- reading means for reading content of the document transmitted by said document transmission means and for outputting resultant readout as image data,
- wherein the document is sent out by said pick-up roller continuously, and when the document stacked on said table is in contact with said pick-up roller, said pick-up roller starts sending out the document until the sent-out document arrives at a predetermined location, then said table moving means lowers said table.
