DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATION(S)
This United States application stems from PCT International Application No. PCT/FR84/00218 filed Oct. 3, 1984.
A large number of persons, particularly those permanently or temporarily suffering from a handicap affecting the limbs, such as victims of fractures, amputees, tetraplegics, sufferers from motor infirmities of cerebral origin, traumatized or badly burnt persons and victims of phocomelia, need for work or leisure purposes to consult documents the pages of which must be periodically turned in one direction or the other in order to permit the documents to be read, consulted, sorted or, more generally, used.
Various forms of apparatus have been described previously, using diverse techniques and methods to turn the pages. In order to turn the pages, they use, inter alia, semi-adhesive tapes or pastes to lift the pages, cam driven in circular motion, mobile skids and even rotating cylinders which grip and then roll the sheets, articulated arms, clamps to fix all the sheets, and so on.
However, no apparatus known at this time provides simultaneously for turning the pages from right to left or from left to right, page by page or continuously, irrespective of the format of the documents (paperback format books, newspapers, large format magazines, etc), the stiffness and quality of the paper or card constituting the sheets and the thickness of the documents.
In contradistinction to this, the present invention makes it possible to implement an apparatus which is of itself able to implement all the movements defined above, under the diverse conditions mentioned, at variable speed as selected by the user and using the resources of microelectronics and microcomputers, employing totally novel means to this end.
To this end, an object of the invention is a device for turning bound together pages of documents placed on a support, fo the type comprising a movable element driven by a motor the operation of which is controlled by a control member to be operated by a user, characterized in that it comprises means for lifting a page and a movable element consisting of a double acting pusher to be situated directly above a document and movably mounted in linear translation in two opposite directions transverse to the bound edges of the pages of a document when the document is placed on the support, the page lifting means and the pusher being also movably mounted perpendicular to the plane of the support to receive the document.
In accordance with other characteristics of the invention: which are preferably fitted with paddles which are advantageously curved, the page lifting means being operative between the symmetrical branches of the pusher; to the other so that the distance between them is variable, locking means being provided for immobilizing the movable branch or branches in the required position; move between an active position in which it is obliged to exert a lifting action on a page of a document placed on the support and an inactive position in which it is neutralized and moved away from said page; page at a height greater than that of the top part of the pusher which has to be situated directly above the document; whereas the other end is intended, in the active position, to be placed in the immediate proximity of a document to be placed on the support; generator; substantially parallel to the bound edges of the pages of a document when the document is placed on the support; pusher and the movable element and controlled by programmed electronic control means associated on the one hand with means for advising the user on operation of the device and on the other hand with a sensor to sense commands from the user and constituting a control member, the device advantageously comprising a link to at least one equipment independent of itself, such as signal transmitter, a mechanism control member or otherwise.
The invention will be better understood from the following detailled description given with reference to the appended drawing. It will be understood that the descrip
