ABSTRACT:
A photocopying device which is to be attached to a conventional photocopying machine, gives to the machine the capability of copying from bound books. The device has a V-shaped book rest for supporting a book in an open condition and a scanning head with a light source. The device can be mounted on a photocopying machine so that light from the scanning head is reflected from a page of the book back to the drum of the photocopying machine, along the same route as is taken by light travelling to the drum during conventional operation, without the device.
