う問題点がある。In the connection structure between these optical fibers, the optical fibers (510a, 510b, etc.) are inserted into the tubular introduction passage whose inner wall is circular or quadrilateral from both ends thereof, and the end faces thereof are abutted against each other. The structure connects the fibers. Therefore, when inserting the optical fiber into the tubular introduction path, the inner wall of the tubular introduction path is scraped at the tip of the optical fiber and a part of it adheres to the end face of the optical fiber, and the suspended matter in the air does not light. It may adhere to the end faces of the fibers, and in such a case, there is a problem that the optical connection performance between the optical fibers deteriorates due to the adhered substances on these end faces.

面に付着する危険性がある、という問題点がある。The above-mentioned conventional optical fiber end face cleaning tool is a cleaning tool in which gauze 700 is impregnated with ethyl alcohol, and the diameter of the optical fiber is 0.125 mm.
Since it is small and cleaning is performed while enlarging and observing with a microscope etc., it requires a lot of time for cleaning, and it is difficult to prepare and carry it because it is necessary to prepare a magnifying tool and ethyl alcohol. However, the method of blowing air with the air spray 720 has a problem that the effect of removing adhered substances is insufficient.
The optical fiber end face cleaning tool 740 in which the elastic body 742 and the cleaning cloth 743 are arranged at the tip of is suitable for cleaning the deep part due to the rod-like shape and the deformation of the elastic body 742. There is a risk that the deposits once removed from the optical fiber end face will fall off the cleaning cloth 743 and attach to the optical fiber end face again, and the cushion sheet 765 and the cleaning sheet 764 are laminated on the main case 761. In the optical fiber end face cleaning tool 760 described above, the cleaning effect can be enhanced by an appropriate pressure on the cleaning sheet 764 on the end face of the optical fiber, but like the rod-shaped member described above, once the adhered substances are removed again, There is a problem that there is a risk of sticking to the end face.

去することができる。In the first embodiment, first, the optical fiber end face cleaning tool 100 is placed on a flat surface such as the table 900, and the end faces of the plurality of optical fibers 510 of the optical fiber connector 500 are cleaned. It is pressed against the surface of the adhesive layer 120 of 100. The pressing force at this time may be such that the surface of the adhesive layer 120 is slightly recessed at the tip of each optical fiber 510 (see FIG. 1B). If the pressing force is too strong, there is a risk that the optical fiber 510 may be deformed or the adhesive layer 120 may be damaged. Conversely, if the pressing force is too weak, the adhered matter on the end surface of the optical fiber 510 may adhere to the adhesive layer 120. Sometimes they don't stick. When it is slightly recessed, the elastic force of the elastic base 110 causes the entire end surface of the optical fiber 510 to adhere to the adhesive layer 120, and the adhered substance can adhere to the adhesive layer 120, thereby adhering the optical fiber 510. When the end face of the optical fiber 510 is separated from the agent layer 120, the adhered substances attached to the end face of the optical fiber 510 are removed and the end face is cleaned. In addition, since the adhered substances may overlap with each other, if the pressing and separating operations are repeated a plurality of times, even in such a case, the adhered substances can be reliably removed.

できる構造となっている。2 (a) and 2 (b) are an exploded perspective view showing a second embodiment of the present invention and a perspective view showing a laminated state thereof. In this second embodiment, the elastic base (11
The pressure-sensitive adhesive layer (120) was adhered and formed on the surface of (0),
A plurality of single optical fiber end face cleaning tools (100) are laminated one after another by sequentially adhering the back surface side of the other elastic base (110) to the adhesive layer (120) of one of the plurality, in order. The cleaning tool 100A has a structure in which a plurality of stacked optical fiber end face cleaning tools 100-1 to 100-n can be sequentially peeled one by one from the frontmost one (100-1).

る。Therefore, when carrying or storing a plurality of optical fiber end face cleaning tools, if these are in separate states as a single unit, for example, protection for the adhesive layer (120) is provided for each. It is necessary to perform it, but in the case of the laminated type, it is easy to carry and store because only the pressure-sensitive adhesive layer (120) of the frontmost one is required, and the laminated state can be held with a fingertip. This facilitates the operation of removing the deposit. Further, when the amount of the adhered substances on the pressure-sensitive adhesive layer (120) of the frontmost one increases and the adhesive effect decreases, a new pressure-sensitive adhesive layer (120) appears by peeling only the frontmost one. Therefore, the updating operation is also easy.

ある。As described above, according to the present invention, an elastic base having a surface of a predetermined size and a thickness, and a pressure-sensitive adhesive layer adhered and formed on the surface of the elastic base, By including the adhesive layer, the end face of the optical fiber is pressed against the adhesive layer to adhere the adhered substance to the adhesive layer, which facilitates preparation and carrying, and facilitates cleaning work. Since the adhered substance sticking to the surface does not fall off from this adhesive layer, it does not re-adhere to the end face of the optical fiber, and the adhered substance is surely removed from the end face of the optical fiber to clean this end face. There is an effect that it is possible to stack a plurality of such optical fiber end face cleaning tools, one adhesive layer on one side and the back side of the other elastic base closely adhered to each other, one by one from the front side. , Can be peeled off sequentially,
By using the laminated type, it becomes easier to carry and store it, and moreover, the last one sheet having a lowered cleaning effect can be peeled off and cleaned by a new optical fiber end face cleaning tool, so that the cleaning efficiency can be improved. The effect of being able to do so is that with a housing case for holding and housing the laminated type optical fiber end face cleaning tool, there is an effect that the carrying, storage and cleaning work can be further facilitated. By constructing a spring that urges the laminated optical fiber end face cleaning tool in the case forward, it is possible to easily obtain an appropriate end face pressing force against the adhesive layer and improve the cleaning work efficiency. The effect is that it can be raised.
