Description

The invention relates to service devices for creating favorable technical conditions for the development of textographic documents, for example, in field conditions.

From the prior art, a writing pad is known (patent for invention RU No. 2367324), made of a rigid base, consisting of a top cover, a bottom cover and side walls that are rigidly connected to each other and flush with the covers on three sides: two long and bottom short , and the fourth side is made flush with the covers and is hinged to the bottom cover with the possibility of turning 90 ° down and spring-loaded so that the springs installed inside it symmetrically at the ends of it tend to constantly turn the sidewall to a horizontal position, and on its inner side are fixed symmetrically on the sides two clamps and each is a handle, one end of which is made in the form of a round convex base with a neck that freely passes through a slot in the sidewall, and the other end is in the form of a round tube with a bottom mounted perpendicular to the other end of the handle pivotally with the possibility of vertical movements along a guide tube of larger diameter with a hole a slot coinciding with a slot on the sidewall, to which it is rigidly attached and ends with a bottom, and the lower end of the cylindrical compression spring installed inside rests against it, and with its upper end it rests against the bottom of the round tube of the second end of the handle, and the tip of this tube is made at an angle of 45 ° to its vertical axis in the longitudinal-vertical plane with a bevel down towards the bottom of the tablet, and on the left on the upper cover of the tablet in the middle of the long side, a rectangular clamping bar with lugs at the left ends, spring-loaded from two sides with cylindrical torsion springs, and in the middle of the bar, on its right edge, an L-shaped stop is rigidly made, while the axes of the springs are U-shaped, and their ends are rigidly fixed on the vertical surface of the sidewall so that the spring does not touch the surface of the sidewall and is flush with the surface of the top cover.

The main disadvantage of this technical solution is the difficulty of using in the dark and the complexity of the design.

The technical objective of the claimed invention is the development of service devices for creating favorable technical conditions for the development of textographic documents, for example, in field conditions.

The solution of the technical problem is achieved by the fact that the tablet has a flat rigid base of a rectangular shape, in the center of the upper face of the front side of which a clamping bracket is built in to fix the paper, and LED strips are built in along the edges of the faces adjacent to it, connected to a battery and a switch mounted in the back side base, and: the battery is equipped with a connector for connecting a charger, a compass is fixed in the right edge of the upper edge on a mount that folds 90 degrees to the back side, the front side of the base is made of non-slip material, a contrast grid is applied to the base with a step of 0.5 cm, in the base has a built-in RFID tag, the back of the base is equipped with four pairs of rings made of elastic material to hold writing utensils and a pocket for placing a ruler.

In order to be able to control the tablet location modes, the RFID tag can be made active.

The RFID tag can be made passive to enable the tablet to be permanently located.

To simplify the storage of the ruler, the pocket for placing the ruler can be made parallel to the long edge of the base.

To simplify the storage of the ruler, the pocket for placing the ruler can be made parallel to the short edge of the base.

The technical result achieved by the set of features of the claimed invention is to simplify the development of text-graphic documents in the dark.

Tablet (figure 1 - front side, figure 2 - back side):

1 - flat rigid base of rectangular shape,

2 - clamping bracket for fixing paper,

3 - LED strips,

4 - power supply with a switch,

5 - compass mount,

6 - compass,

7 - contrast grid,

8 - a pocket for placing a ruler;

9 - rings for holding writing instruments.

The tablet has a flat hard rectangular base. In the center of the upper edge of the front side of the tablet, a clamping bracket is built in to fix the paper.

Along the edges of the side (adjacent to the top) faces of the base, LED strips are built-in. LED strips are connected to a battery and a switch mounted on the back of the base, and are turned on manually at night to illuminate the front of the tablet.

For charging, the battery is equipped with a connector for connecting a charger.

To simplify the application of inscriptions on paper, a contrast grid is applied to the base of the tablet in 0.5 cm increments (if the base is dark, then the grid is light, and vice versa).

A compass is fixed in the right edge of the upper edge of the tablet on a 90-degree mount that folds to the back. In working condition, the compass protrudes beyond the upper edge of the tablet; in the non-working state, the mount leans back 90 degrees and the compass is pressed against the back of the tablet.

To ensure that the paper does not slip when writing, the front side of the tablet base is made of non-slip material.

An RFID tag is built into the base of the tablet to facilitate locating the user's location of the tablet, or the location of the tablet when it is stored (for example, at night) or if it is lost.

The back side of the tablet base is equipped with four pairs of rings made of elastic material, glued or sewn to the base, designed to hold writing instruments. The diameter of these rings corresponds (by 1-3% more) to the diameter of the writing instruments used, the distance between the rings of one pair is 5-10 cm (determined by the length of the writing instruments used).

The back side of the base of the tablet is a pocket for placing a ruler.

The tablet user fixes a sheet of paper with a clamp, removes the necessary writing instruments from the rings, and applies the necessary information. At night, the front side (paper) can be illuminated using LED strips.

If necessary, drawing information on the map, you can use the compass: its mount leans back, the compass becomes visible to the user.
