Description

  The present invention relates to a two-dimensional code display device that reduces the labor of wiring work and an optical fiber wiring board equipped with the two-dimensional code display device.

In the optical fiber distribution board, a large number of optical fiber connection portions are provided. These optical fiber connection portions may cause problems when wiring work is performed later, for example, if the source / destination of the line is not clearly indicated. Therefore, in order to display various information such as lines for individual optical fiber connection portions, it is common to provide a display portion.
As the conventional technology of such a display unit, the most commonly performed one is a direct display such as writing a predetermined item with a writing instrument in the optical fiber connection unit, or the optical fiber connection unit. There is also an indirect display such as attaching a name tag on which predetermined items are written.

  In addition, as another prior art of display, for example, in the prior art described in Patent Document 1 (Invention name: code with connector and its identification symbol reading method), it is displayed on the boot portion of the cord with connector (optical code). The boot portion is detachable while providing an identification symbol by providing a portion, and the identification symbol includes a one-dimensional barcode and a two-dimensional barcode (so-called QR code). Yes. This corresponds to the direct display described above.

  In the prior art disclosed in Patent Document 2 (Invention Name: Optical Fiber Identification and Printing Method) or Patent Document 3 (Invention Name: Optical Fiber Core Identification Code Reading Method and Reading Device), a two-dimensional code is used. The present invention relates to a printing method in the case where a tag printed with a is attached to an optical fiber core and a reading method using a two-dimensional code reader.

JP 2000-277212 A (paragraph number 0018, FIG. 2) Japanese Unexamined Patent Publication No. 2000-108414 (FIG. 4) JP-A-11-353454 (FIG. 3)

  In the indirect display of the prior art described above, information is often described in an unstable part such as a display tag attached to an article requiring information. For this reason, there are many cases where smooth reading is impossible when reading the display unit, and there is a possibility that troubles may occur in the article due to repeated loads due to contact with the support of the finger etc. and the reading device etc. The reading time was long and wasted.

  Further, in the configuration based on the direct display disclosed in Patent Document 1, the display portion is provided in the boot portion. However, when the optical fiber connection connectors are arranged in a matrix, a large number of optical fiber connection connectors on the inner side are There is a problem that the boot is not visible because it is hidden behind the outer optical fiber connector and the display portion is difficult to see. This was the same when reading with a code reader.

In the configurations disclosed in Patent Documents 2 and 3, the two-dimensional code reader is configured to read a two-dimensional code at a distant position, but it is not easy to determine the field of view of the two-dimensional code. If the two-dimensional code is continuously arranged, it is difficult to distinguish the adjacent two-dimensional code from the adjacent two-dimensional code.
Even if the two-dimensional code reader is placed and recognized in contact with or close to the two-dimensional code in consideration of these problems, the two-dimensional code is misread due to slipping or shaking of the two-dimensional code reader. There was a risk.

  Therefore, the present invention has been made to solve the above-described problems, and its purpose is to prevent misreading with a simple configuration, to reduce work time by reliable reading, and to add a load to an article. An object of the present invention is to provide a two-dimensional code display device for preventing troubles and an optical fiber wiring board equipped with the two-dimensional code display device.

The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a two-dimensional code display device according to the present embodiment, in which FIG. 1 (a) is a front view and FIG. 1 (b) is a side view.
The two-dimensional code display device 1 includes a two-dimensional code display unit 2 and a reading guide 3 as shown in FIG.

The two-dimensional code display unit 2 displays one or a plurality of two-dimensional codes. For example, as shown in FIG. 1A, it may be a matrix-like display unit having a plurality of rows and columns, or a single display unit (not shown). There are various standards for the two-dimensional code, and specifically, a matrix-type QR code, Data Matrix, Maxi Code, or a stacked barcode type PDF417 can be adopted. In this embodiment, for the sake of concrete explanation, it will be described as a QR code.
As will be described later, the reading guide 3 has a function of guiding the code reader reading unit 6 to the reading position of the two-dimensional code display unit 2 (see FIGS. 2A and 2B). One is provided.

Such a reading guide 3 will be described. FIG. 2A is a state diagram before placing the code reader reading unit. FIG. 2B is a state diagram after the code reader reading unit is placed.
The reading guide 3 is formed by a guide plate 4 and a pedestal 5 as shown in FIGS. 2A and 2B. The guide plate 4 includes a guide body 4a and a through hole 4b.

The guide plate 4 is formed, for example, by forming a through hole 4b in a plate-shaped guide body 4a, and is formed in a lump by, for example, molding with synthetic resin.
The pedestal 5 is, for example, a plate-shaped pedestal formed of metal, synthetic resin, or the like, or, as will be described in detail later, may be a substantially U-shaped pedestal as shown in FIGS.
When such a guide plate 4 is mounted on the pedestal 5, the through hole 4 b forms one reading guide 3 by blocking one opening by the pedestal 5. The reading guide 3 is adapted to the outer shape of the code reader reading unit 6. In this embodiment, the reading guide 3 is matched with the outer shape of the code reader reading unit 6, which is a quadrangular pyramid-shaped guide convex portion. It is a quadrangular frustum-shaped guide recess. For this reason, the one where the opening area of the through-hole 4b is larger is the front side of the guide plate 4, and the one where the opening area of the through-hole 4b is smaller is the back side of the guiding plate 4.

Next, the use of such a two-dimensional code display device 1 will be described with reference to the drawings.
The reading surface of the code reader reading unit 6 is brought close to the reading guide 3 from above the two-dimensional code display unit 1 so that the reading surface of the code reader reading unit 6 reaches the opening surface of the reading guide 3 as shown in FIG. . As described above, since the opening area on the front side of the reading guide 3 is large, the code reader reading unit 6 which is a quadrangular frustum-shaped guide convex portion can easily enter the quadrangular pyramid-shaped guide concave portion of the read guide 3. Be guided.
Then, finally, as shown in FIG. 2B, the reading surface of the code reader reading unit 6 reaches the display surface of the two-dimensional code display unit 2, contacts the pedestal 5, and stops. In this state, since the code reader can reliably read the two-dimensional code while suppressing slipping and shaking, there is almost no possibility that an error in reading due to the displacement of the code reader or the like will occur.

The two-dimensional code display device 1 of the present invention can be variously modified. 3A is an enlarged view of a two-dimensional code display device using a two-dimensional code display unit using a seal, FIG. 3A (a) is an enlarged plan view of a reading guide, and FIG. 3A (b) is a cross-sectional view taken along line AA of the reading guide.
