DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a draft/copy holder including a plate-shaped draft/copy holder and means on the holder adapted to fasten the draft/copy holder to a support and carrying means.
BACKGROUND OF THE INVENTION
Draft/copy holders are known in many variations such as, for example, music stands wherein a holding means of the draft/copy holder is, for example, a pivotable arm linked, bearing connected, or through a screw pinching device connectible with a support and carrying means such as, for example, a table, a bookshelf, a board of the like.
If such a pivotable arm, possibly in the shape of a tong mechanism, must be installed at, for example, a computer CRT console or display screen such as at a keyboard arranged below such screen console, it has been found that it can be difficult to position the holding means at a suitable support and carrying means without the connecting means creating an obstacle for one or more of the accessory devices, occupying valuable table space of the work table, or hindering proper viewing of the printing device, etc. Experience also shows that, due to the differences existing in light intensity as absorbed between an internally illuminated display screen and the observed elimination of the operating devices around the display screen including also light from the surroundings, namely, full daylight or artificial illumination, for example, without the presence of daylight, the arranging of the operating devices at a work station is a very critical matter since, for example, consideration must be given to operators of the work station with respect to an ergonomical point of view, such as, for example, the height of the devices above the floor, the allowing for reasonable with-in-reach distances to the individual devices as well as usable with-in-sight distances playing a fundamental role by any practical use of the work station.
Draft/copy holders have been proposed which are adapted to be arranged in the range between the lower front edge of the display screens, between the front edge of carrying boards for such display screens, and a keyboard arranged below. This solution has certain advantages; however, a disadvantage resides in the fact that the eye must be physically moved between the draft/copy and the display screen in such a manner that it is necessary to simultaneously accurately remember which lines have been reached as viewed in the two visual directions, or, in case of graphical presentations, remembering which locations or spots are compared by watching, etc., that is, there are two versions to remember, that of the display screen and that of the draft/copy.
SUMMARY OF THE INVENTION
The aim underlying the present invention essentially resides in providing a draft/copy holder of the above mentioned type by which, on the one hand, an easy installation and possibly a fast removal of the draft/copy holder for one reason or another is possible and, on the other hand, a fast comparison between the contents of the display screen and the draft/copy is achieved, with the draft/copy holder being inexpensive to manufacture.
Advantageously, the draft/copy holder of the present invention can easily carry, for example, data lists, either in loose shape or data lists which remain attached to a printer.
In accordance with advantageous features of the present invention, the plate of the draft/copy holder is shaped larger than required due to the expected sizes of the draft/copies, and, an oversized portion of the plate, through an oblique bending, namely, a side edge of the plate shaped draft/copy is bent in a rearward direction through an angle which is preferably less than 90.degree.. A bending angle of 60.degree. is, in practice, a suitable angle size, and the front of the bent portion is at one or more locations fitted with a detachable locking arrangement adapted to grip correspondingly shaped locking arrangements arranged on the carrying and support means. Suitable locking arrangements may, for example, be fashioned of VELCRO strips, rib
