Abstract

PURPOSE:To enable a measurer to measure accurately and safely with actual dimension without requiring re-measurement of line double or triple times or without including the possibility of skipping over lines even when measurement is interrupted in the midway of the measurement. CONSTITUTION:In a rotary transmission gear mechanism, a rotation of a gear 1 is doubled by the rotational engagement between the outer periphery of the gear 1 and a small gear of a gear 2. The rotation is further doubled by the rotational engagement between a large gear, which is one of the pair with the small gear 2, and a gear 3, and is still further doubled by the rotational engagement between a large gear, which is one of the pair with the gear 3, and a small gear 4. A slit plate 19 which is one of the pair with the gear 4 rotates enlargedly and makes one round every time the gear 1 shifts (rotates) 1mm. on its periphery. According to the rotation of the plate 19, ten slits 6 equi-spaced on the plate 19 rotates in a groove of a photo-microsensor 5 intermittently intercepting the optical path of the sensor 5 so as to apply input signals to a computer. One signal is applied every one interception and inputted to the computer. Thus, the actual length of the line is instantly indicated on an indication window 16 by tracing the line to be measured by the gear 1.

Description

[Detailed Description of the Invention] The present invention instantly displays addition, subtraction, multiplication, and division in the actual size using an electronic calculator by tracing the line length on a drawing using a gear at the tip and using a pre-selected and displayed scale scale. It is an accurate measuring instrument that does not double or double measure lines on drawings due to its anti-reverse rotation mechanism.

Therefore, when measuring the length of a line on a drawing, as shown in Figure 4 of the drawing, the line on the drawing is traced using a roller (20) protruding from the tip of a dial meter as shown in IJ Rizu Street. In most cases where length measurement is done using a dial type and is indicated between the scales, the reading is left up to the worker's intuition or conscience, and the current situation is that the scale number is added, subtracted, multiplied, and divided to the read value. The equipment is designed so that the roller (20) rotates in forward and reverse directions and leaves no trace on the line being traced, so once you start measuring, you have to stop the measuring device from one end of the line to the other. Not only are they unable to deal with unexpected calls such as visitors or phone calls, but they are also unable to do so.
In order to make a mistake in measurement, the measurer used the neural surface drawing scale to be too large (1/600, 1/500, etc.) Moreover, it is hardly used as a piping work drawing, and the installer only uses it as a building. Construction W so that it does not get in the way of the building so as to weave between the building! In order to design and draw piping diagrams in the drawings, the length of the pipes that are included in the piping is not accurately indicated on the drawings, and after these drawings are drawn, the plumbing company has to measure the actual size of the drawings.The number 1 is the scale of the drawings. Add, subtract, multiply, and divide the frequencies and dig out the confirmation letter. Therefore, if the line length on the drawing is 10mm (1) wrong, the actual size will be 600 times the actual size. We are incurring the unnecessary expense of rebuilding.
Currently, no reorganized version of these measuring instruments has been developed.

The present invention eliminates the above-mentioned drawbacks, allows the measurer to safely and accurately display the actual dimensions, and allows the measurer to safely repeat the measurement even if he or she interrupts the measurement mid-way, without skipping any lines or skipping the measurement. -ag1111+ The purpose of this is to inform the measurer of the meter so that he can submit an accurate and complete estimated amount, thereby alleviating the nerves of the meter and allowing him to work in a healthy manner.
! ! It is a small vessel.

The configuration of this invention will be explained with reference to the drawings.
Figure 1 of +i is a gear configuration diagram in which only the rotation expansion transmission mechanism part to the slit plate (19) is taken out from the case (11) by passing the wire length of the present invention into the gear (1 g).
The gear (2) is multiplied by the pinion of the gear (2) that meshes with the outer periphery of the gear (1), and the large gear that is paired with this pinion meshes with the gear (3), and the large gear that is paired with the gear (4) is doubled.
), the slit plate (19) paired with the pinion (4) rotates in an enlarged manner, and moves (rotates) 1 mm on the circumference of the gear (1), making one rotation. However, when the slit plate (19) is divided into ten equal parts (6) and rotates in the groove of the photo-microsensor (5), it cuts off the optical path of the photo-microsensor or passes the optical path through. When the rotation is cut off, a signal is input to the electronic TTG device and recorded.Furthermore, the shaft (12) of the gear (3) and the case (1)
A plate-shaped coil spring (10) whose inner diameter is slightly smaller than the shaft diameter is press-fitted into the shaft (13) fixed to 1), and the tooth 1f (3) is attached to this plate-shaped coil spring (10). When the plate-shaped coil spring (10) rotates in the winding direction, the inner diameter of the plate-shaped coil spring (10) is further compressed by frictional force, making it impossible to rotate. Because of this, the frictional force is significant ~
The gear (3) on the shaft (12) holding this gear acts as a clutch, so this gear (3) and the intervening gear (1) are
The sponge can rotate in only one direction, and the relationship of the combinations is shown in detail in Figure 3 of the drawings, and Figure 2 of the drawings is a plan view of the intervening gear relationship diagram of Figure 1 of the drawings. The roller (7) is in contact with one point on the outer circumference of the gear (1) and constantly transfers ink to the outer circumference of the gear (1).
When tracing the lines on the drawing, transfer this transferred ink to the drawing and leave the traces of the gear (1) on the drawing! In addition, the sponge roller (7) has an ink case (8) attached to it, and the rotary receiver is constantly replenishing ink from the case (9) and is transferring ink to the gear (1) without interruption. are shown in Figures 1 and 2 of the drawings. Figure 5 of the drawings showing a measuring instrument in which these mechanical parts and an electronic calculator are housed in a case (11) is a side view; FIG. 6 is a plan view.

Since the present invention has the above-described structure, if it is not to be used, first the ink case (8) containing ink is pushed into the rotary receiver case (9).
) until the ink is absorbed into the case (11).Turn on the tt calculator switch knobs (1, 8).Next, use the number key buttons to enter the same number as the scale of the drawing in the display window ( 15). Now you are ready to measure. Place the line on the drawing to be measured on the gear (1) protruding from the tip of the case.
If you trace it, the actual size will be displayed on the display window (16) instantly, and even if you stop the measurement midway through, the trace will still remain on the drawing due to the ink, so you will have to start measuring again. Time can be easily measured by tracing the gear (1) from the edge of the ink mark. /I
! If you return the switch knob (18) to OFF after the adjustment, the calculator function will automatically return to its original state. It is possible to measure
