Abstract
A document reading apparatus used in a printer or a facsimile. The apparatus includes a document reading confirmation mechanism for printing a character or mark on a document to allow confirmation of whether the document has been read by the document reading apparatus or not. The confirmation mechanism includes a movable guide plate and an auxiliary guide slidably engaged with and cooperating with the movable guide plate to provide together a guide surface for the entire surface of the document at all times when the movable guide plate is placed at any position. A printing head is mounted to the movable guide plate to record a document reading confirmation mark on the document while it is conveyed.
Claims21
A document reading confirmation mechanism arranged in a document reading apparatus for recording a document reading confirmation mark on a document to allow confirmation of whether the document has been read by the document reading apparatus or not, said mechanism comprising:
- a guide means providing a guide surface for a document conveyed in a predetermined conveying direction, said guide means including a movable guide plate, said movable guide plate being movable in the transverse direction with respect to the conveying direction within a predetermined range;
- and
- recording means mounted onto the movable guide plate of said guide means for recording a document reading confirmation mark on the document while the document is conveyed along the guide surface of said guide means.
A document reading confirmation mechanism arranged in a document reading apparatus for recording a document reading confirmation mark on a document to allow confirmation of whether the document has been read by the document reading apparatus or not, said mechanism comprising:
- a first guide means providing a guide surface for a document conveyed in a predetermined conveying direction, said first guide means including a movable guide plate being movable in the transverse direction with respect to the conveying direction within a predetermined range;
- a second guide means providing a guide surface in an opposite relationship with the guide surface of the first guide means to cooperate with the guide surface of the first guide means for forming a guide passage between the guide surface;
- and
- recording means mounted onto the movable guide plate of said first guide means for recording a document reading confirmation mark on the document while the document is conveyed along the guide passage.
