BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention:
The present invention relates to an apparatus for permitting the viewing of a large number of entries printed on a sheet leaving a calculating machine, such as a sheet unrolled from a paper roll attached to the calculating machine. In particular, the present invention relates to a supporting plate which is attached to the upper side of a calculator and which rests on the horizontal top surface of the calculator to support the paper coming out from the calculator, the supporting plate being laterally adjustable.
2. Description of the Related Art:
In a conventional calculator, the paper leaves the printing part of the calculator and passes a small plate in order to prevent the paper from again being caught in the calculator together with the paper entering the calculator from the paper roll. Since the paper tends to curl up once it is discharged from the calculator, one can see very few entries printed on the paper strip as it rolls up behind the calculator. As the number of printed entries increase, they cannot readily be seen or annotated, as by underlining. Therefore, a review of the entries is time consuming and difficult unless the paper is cut into sections. However, cutting the paper into sections makes impossible a continuous presentation of the entries at a later time. This is a particular problem in certain professions, such as accounting, auditing, economics and banking where a large number of entries are calculated at a time.
SUMMARY OF THE INVENTION
It is an object of the present invention to eliminate the above-mentioned disadvantages. For this purpose, the present invention provides an apparatus for permitting the viewing of a large number of entries printed on a sheet leaving a calculating machine, which apparatus comprises an elongate bar having a longitudinal track, a support plate having a lower end fittable in the track and an elongate fastening means connected to the elongate bar and extending transverse to the length of the elongate bar. The track has means for supporting the support plate fitted in the track at an angle of between 35 and 70 degrees with respect to the horizontal. The track has a length greater than a width of the support plate so that the position of the support plate along the track may be adjusted. The support plate includes means for laterally guiding longitudinal edges of a sheet supported therein. The elongate fastening means includes means for securement to a calculating machine. The elongate bay may be secured to the calculating machine by the fastening means at a position where a sheet leaving the calculating machine may be supported and guided by the guide plate fitted in the elongate bar.
The above construction provides advantages including more rapid observations since one need not manipulate the coiled up discharged paper in order to see the various entries. Since a large number of entries are immediately visible to the observer, it is easier to understand the progression of numbers in the various entries. The paper sheet can be cut at a desired point without regard to how much can be seen at a time, and one need not glue together different parts of the sheet which were cut only to permit easy observation.
According to a feature of the invention, a device for securing accessories, such as a pencil or eraser, can be attached to the back of the support plate.
According to another feature of the invention, a transparent plate having optical magnifying means can be fitted to the support plate for magnifying the size of entries printed on the sheet supported and guided in the support plate. This is particularly advantageous for calculators which produce small printing.
