Shape for identifying front and back sides of paper and the like

Abstract

To solve the problem that the efficiency of time, labor and cost is low because of a failure due to overlooking even though useless labor for confirming the front and back of paper or the top and bottom of a postcard is indispensable in the conventional manner.SOLUTION: By cutting out one corner of the postcard as shown in Fig. 1, the postcard whose front and back or top and bottom are different can be found instantaneously as shown in Fig. 3, and by protruding the postcard, the postcard can be easily arranged by picking and pulling out a part to be a knob 3.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a shape that allows the front and back of a sheet of paper or the like to be distinguished from the top and bottom at a glance. [Background technology]

[0002] Conventional paper and the like does not have a simple means for aligning the front, back, top and bottom correctly at a glance. [Prior art documents] [Patent documents]

[0004] [Non-Patent Document 1] 0000000000000000000 Summary of the Invention [Problem to be solved by the invention]

[0005] In the past, it was time-consuming to check the alignment of the front and back of paper (postcards, copy paper, ballots, etc.) one by one, which often led to mistakes. For example, when printing postcards, there were mistakes such as printing the address upside down on the addressing side or printing the destination address on the text side. [Means for solving the problem]

[0006] The present invention is characterized in that one of the four corners is notched or colored in advance at the product stage so that paper with misaligned top and bottom can be found in an instant. [Effects of the Invention]

[0007] Conventional techniques for separating the top and bottom halves of a sheet using machines are costly, but the present invention makes it possible to easily determine the top and bottom halves of a sheet without using such machines, which has the advantage of reducing mistakes and improving work efficiency. [Brief explanation of the drawings]

[Figure 3] This is a perspective view of a state in which a sheet of paper 2 is upside down among a stack of postcards with notches 6, and it is immediately clear that the sheets are not aligned. [Figure 4] FIG. 10 is a front view of an icon displayed on the printer body so that printing can be performed correctly depending on the position of the notch 6. [Figure 5] FIG. 1 is a front view of a banknote 4 having a notch 6 for each denomination. [Figure 6] FIG. 10 is an enlarged view showing that the type of banknote 4 can be easily selected. DETAILED DESCRIPTION OF THE INVENTION

[0009] By notching one corner of the paper, it is possible to easily see which paper has different top and bottom sides, and to pick up the protruding part as a knob 3, and sort and arrange it correctly.

[0010] In Figure 3, the postcard 1 has a notch at the top right corner to make it easier for right-handed people to pick it up, but for left-handed people, the entire postcard stack 7 can be turned over left to right to make it easier to pick up.

[0011] The size of the notch width 5 can be determined as a standard for each paper type by each industry so that it is easy to pick up with fingers, tweezers, machines, etc., depending on the circumstances of each paper type. [Example]

[0012] To make the embodiment of the present invention easier to understand, as shown in Figure 1, postcards 1 with a front / back top / bottom distinguishable shape, such as paper with a notch 6 of the present invention, are bundled as shown in Figure 2 with the front / back top / bottom reversed. However, if there are any papers 2 with the front / back top / bottom reversed mixed in with the postcard stack 7, they can be instantly identified by pinching the knob 3, and pulled out and straightened, as shown in Figure 3.

[0013] In addition, if the icon in Figure 4 is displayed on the printer's paper loading section to indicate which way the paper should be loaded, printing errors can be eliminated without having to worry about the front, back, top, and bottom.

[0014] The shape of the notch 6 in the upside-down paper 2 can be a curved line, but does not necessarily have to be a straight line.

[0015] When banknotes 4 of the same size are to be oriented in the same direction, sorting can be made easier by changing the angle of the notch 6 as shown in Figure 5.

[0016] When the three types of banknotes 4 in Figure 5 are stacked as shown in Figure 6, they can be easily separated by paying attention to the height of the right edge, and it is difficult to mistake small denomination banknotes for large denomination banknotes at a glance due to the relationship between the height of the notches 6, differences in design, differences in color, etc. [Industrial Applicability]

[0017] This eliminates the waste of damaged paper caused by mixing papers with different top and bottom sides when printing postcards, etc.

[0018] Generally, paper has a front and back, and some paper, such as inkjet paper, requires the effort of checking the front and back before printing. If the front and back are mixed up, the inkjet paper and the effort involved will be wasted, but this can be prevented.

[0019] When collecting voted ballots, it becomes easier to organize them by correcting the front, back, top and bottom.

[0020] It can also be applied to items where a difference in the front and back of the product would cause problems in business. [Explanation of symbols]
