Description

  The present invention relates to a criminal investigation forensic assistance sheet for placing a criminal investigation object such as evidence.

In current criminal investigations, DNA tests are frequently performed as scientific investigations.
In addition, DNA inspection cannot be performed accurately if a small amount of foreign matter is mixed in the object to be verified, or if a fingerprint of a person unrelated to the crime is attached afterwards. Therefore, in order to increase the accuracy of the appraisal, careful attention is given to contamination due to adhesion of fingerprints and foreign matters.

Conventionally, in order to prevent the above-mentioned contamination, instead of placing the object to be judged directly on a table or the like, a cloth sheet designed to prevent contamination is placed on the table or the like and placed on the cloth sheet. He was trying to place an object to be verified.
In addition, the prior art literature as a prior art is not investigated.

Although the appraisal object was placed on a sheet designed to prevent contamination as described above, conventional cloth sheets are always kept clean by washing (washing). In addition, it takes time and effort to store it in a clean state, and the price is high.
An object of the present invention is to provide an inexpensive identification assistance sheet that can be stored in a clean state.

  In the first invention, one sheet body is folded in two with a fold line formed at a position shifted from the center in the width direction as a boundary, so that the width of one sheet piece is larger than that of this one sheet piece. The other sheet piece is formed wider. When these two sheet pieces are overlapped and brought into close contact with each other, a scale that is continuous in the longitudinal direction is printed on the exposed portion of the other sheet piece that is exposed from the overlapping portion with one sheet piece.

In the second aspect of the invention, the sheet body is made of resin, and cut lines such as perforations are provided at predetermined intervals in the longitudinal direction.
Note that the cut line is not necessarily limited to perforations. In short, any form may be used as long as the sheet body folded in half can be cut without using a tool such as scissors.
In a third aspect of the invention, the sheet body is wound in a roll shape with the surface of the exposed portion on which the scale is printed facing inward.

According to the first invention, since the sheet body is folded in half, contamination can be completely prevented until the sheet body is unfolded as long as sufficient consideration is given in the manufacturing process. In addition, since the sheet body can be stored in a folded state, the sheet body can be kept clean during storage.
Therefore, even if an object to be identified is placed or wrapped on the sheet body, contamination to the object to be identified can be prevented, and DNA identification is not affected.

Also, when taking a picture with the object to be examined placed on the unfolded sheet body, the scale printed on the exposed part of the other sheet piece is also photographed at the same time to determine the size of the object to be judged on the photograph. It can be so.
Therefore, when the appraisal object is vertically long, it is better for the person who performs the appraisal to see the scale and appraisal object when the sheet body is developed on the table with the scale in the vertical position. Will be easier to understand. On the contrary, when the appraisal object is horizontally long, it is easier to understand the correspondence between the scale and the appraisal object when the sheet body is developed on the table with the graduation sideways.

And since the scale printed on the exposed part of the other sheet piece of the sheet body can be seen even in a state where the sheet body is folded in half, if it is known in advance whether the object to be verified is vertically long or horizontally long, The development position of the sheet body with respect to the table can be determined based on the scale.
As described above, since the position of the sheet main body is determined based on the scale, it is not necessary to adjust the position of the scale corresponding to the object to be identified after the sheet main body is expanded.

Also, during appraisal work, we are trying to prevent foreign objects such as fingerprints and hair from people who are not related to criminals from adhering, but there is no possibility that they will adhere in the process of moving the sheet body in various ways. It's all right. However, in the present invention, since the sheet body does not have to be moved many times on the table, such a worry is almost eliminated.
Furthermore, with the sheet body folded in half, the exposed portion of the other sheet piece is exposed from one sheet piece, making it easier to pick up the end of one sheet piece, so both sheet pieces are easy to peel off Become. In particular, the person who conducts the appraisal pays close attention not to attach his / her fingerprints by wearing gloves, but according to the present invention, both sheets can be peeled off even when wearing gloves.

Further, since the scale is printed on the exposed portion of the other sheet piece that is exposed when the sheet body is folded in half, the exposed portion can be printed while the sheet body is folded in half. Since the scale can be printed while the sheet body is folded in this way, no foreign matter is mixed into the overlapping surface of both sheet pieces during printing.
Moreover, since the portion on which the scale is printed can be clearly seen, it is possible to consciously avoid the exposed portion when placing or wrapping the object to be verified. Therefore, even if a foreign object adheres during printing, it does not affect the identification.

According to the second aspect of the present invention, the cut lines are inserted at predetermined intervals, so that no special tool such as scissors is required when cutting the sheet body. Since a special tool is not required, for example, there is no risk that foreign matters attached to the tools adhere to the sheet body.
Moreover, since the cut line is formed at a predetermined interval in the longitudinal direction of the sheet main body, the size of the sheet main body per unit cut from the cut line can be kept constant.
Furthermore, since the sheet body is made of resin, it can be easily washed, or it can be disposable.

  According to the third invention, since the surface of the exposed portion on which the scale is printed is set inward, the sheet body is folded in two and wound in a roll shape, both sheet pieces are conveyed in the process of transporting the roll-shaped sheet body. Foreign matter does not adhere to each of the contact surface and the exposed portion.

FIG. 1 is a plan view of a state in which the seat body is unfolded. FIG. 2 is a perspective view of a state in which the sheet body is folded in half.

In the illustrated embodiment, a fold line 2 is formed along the longitudinal direction of a sheet body 1 made of a resin sheet such as polyethylene, and a pair of sheet pieces 1a and 1b are defined with the fold line 2 as a boundary. ing.
The width dimension of the other sheet piece 1b in the direction perpendicular to the fold line 2 is made larger than the width dimension of one sheet piece 1a in the direction perpendicular to the fold line 2. Therefore, when both sheet pieces 1a and 1b are folded back from the fold line 2 and the sheet pieces 1a and 1b are brought into close contact with each other, as shown in FIG. 2, the edge portion of the other sheet piece 1b is exposed. The exposed portion 1c is used.

  A scale 3 continuous in the longitudinal direction is printed on the exposed portion 1c. When the scale 3 is printed, both the sheet pieces 1a and 1b are brought into close contact with each other, and the sheet main body 1 in contact with them is placed in the longitudinal direction. The scale 3 is continuously printed on the exposed portion 1c. The scale 3 printed in this way has a scale of 1 cm, and the display forms are different so that the scale lines indicating 1 cm unit, 5 cm unit, and 10 cm unit can be distinguished from each other.

Since the scale 3 is continuously printed on the exposed portion 1c while keeping both the sheet pieces 1a and 1b in close contact with each other as described above, the contact surfaces of the both sheet pieces 1a and 1b are not exposed during printing. . Accordingly, foreign matter or the like generated during printing does not adhere to the contact surfaces of both sheet pieces 1a and 1b.
In addition, since the portion on which the scale 3 is printed can be clearly seen, the exposed portion 1c that has been printed should be consciously avoided even when the object to be identified is placed on or wrapped around the unfolded sheet body 1. Can do. Therefore, even if a foreign object adheres during printing, it does not affect the identification.

Further, the sheet main body 1 is formed with a cut line 4 formed of perforations having a predetermined interval in the longitudinal direction thereof. The cut line 4 traverses the sheet main body 1 in a direction orthogonal to the fold line 2.
The cut line 4 is not necessarily a perforation. For example, the cuts of a certain length may be continued at a predetermined interval, or the holes having a certain shape may be continued. In short, the form of the cut line 4 is not limited as long as the sheet body 1 can be cut from the cut line 4 without using a cutting tool such as scissors.

When the sheet body 1 cut from the cut line 4 is unrolled and developed, the unit sheet body 1 having a predetermined area shown in FIG. 1 is configured. Therefore, the size of the sheet body 1 per unit cut from the cut line 4 can be kept constant.
The sheet body 1 on which the scale 3 is printed is wound in a roll shape with the scale 3 side inward, but the state wound in a roll shape is not shown.

Since the sheet body 1 is wound in a roll shape with both the sheet pieces 1a and 1b in close contact as described above, both the sheet pieces 1a and 1b are not peeled off during storage or conveyance. Accordingly, no foreign matter or the like is mixed between the sheet pieces 1a and 1b that are in close contact with each other. In addition, since the exposed portion 1c is also wound inside, foreign matter or the like is less likely to adhere to the exposed portion 1c.
In addition, even if the sheet body 1 is not wound in a roll shape, as long as both the sheet pieces 1a and 1b are in close contact with each other, no foreign matter is mixed in between them.

When the sheet body 1 is used, the sheet body 1 with the sheet pieces 1 a and 1 b in close contact is unwound from the roll, and the unwound sheet body 1 is cut off from the cut line 4.
When the sheet main body 1 is unwound from the roll, both the sheet pieces 1a and 1b are in close contact with each other. Even if the sheet main body 1 is cut off from the cut line 4 in this state, the foreign matter at the time of cutting is between the two sheet pieces 1a and 1b. There is no contamination.

Then, the position and direction of the scale 3 on the table (not shown) are specified depending on whether the object to be verified is vertically long or horizontally long. When the position and direction of the scale 3 on the table can be specified in this way, the exposed portion 1c is pressed with one hand, and the end of one sheet piece 1a is picked and developed with the other hand.
At this time, since the exposed portion 1c is provided, the end of one sheet piece 1a can be grasped while holding the exposed portion 1c with one hand. Demonstrates power when wearing gloves.

  In other words, the person who conducts the appraisal pays close attention not to attach his / her fingerprints by wearing gloves, but if he / she wears gloves, the feeling of the fingertips becomes dull, so if both sheet pieces 1a and 1b are the same If they are close in size, it will be difficult to remove them. However, since the exposed portion 1c is provided in this embodiment, even if a glove is worn, if the exposed portion 1c is pressed with one hand and one sheet piece 1a is shifted with the other hand, the side portion is slid. The end of the sheet piece 1a can be easily pinched.

Further, as shown in FIG. 1, when the object to be verified is placed on the unfolded sheet main body 1 and the scale 3 is also photographed at the same time when the photograph is photographed, the size of the object to be identified on the photograph is determined. it can.
When the object to be verified is vertically long, the scale body and the object to be verified are taken when the photograph is taken when the sheet body 1 is developed on the table with the scale 3 in a vertical state as viewed from the person performing the inspection. The correspondence with things becomes easier to understand. On the contrary, when the appraisal object is horizontally long, it is easier to understand the correspondence between the graduation 3 and the appraisal object when the sheet body 1 is developed on the table with the graduation 3 in the horizontal direction.

  Moreover, since the scale 3 printed on the exposed portion 1c of the other sheet piece 1b of the sheet body 1 can be seen even when the sheet body 1 is folded in half, it is determined beforehand whether the object to be identified is vertically long or horizontally long. If it is known, the development position of the sheet body 1 with respect to the table can be determined based on the scale 3.

  As described above, the development position of the sheet body 1 is determined on the basis of the scale. Therefore, after the sheet body 1 is deployed, it is not necessary to turn the scale body 3 so that the position of the scale 3 corresponds to the object to be identified. . Therefore, it is not necessary to move the unfolded sheet body 1 many times for position adjustment.

Furthermore, since the sheet body 1 is made of resin, it is easy to clean and can be disposable.
In addition, it is natural that the forensic aid sheet in this invention may carry a forensic object other than DNA examination.

  It is most suitable for placing an object to be identified during DNA identification.
