Normally, the reader / writer 11 of the vending machine has a structure that is assembled to the reader / writer mounting opening 25 provided on the front panel 3a of the door 3 as shown in FIGS. Generally, the reader / writer mounting opening 25 is formed in advance according to the shape and size of the initial reader / writer, and the initial reader / writer is mounted in the reader / writer mounting opening 25.

  However, the vending machine may be changed from the original reader / writer to the reader / writer 11 having a different standard (for performance improvement or the like). In this case, the reader / writer is changed, but the changed reader / writer may not be installed in the reader / writer mounting opening 25 as it is due to a difference in size and shape of the reader / writer (due to a difference in specifications). Incidentally, each of the reader / writers 11 shown in the present embodiment indicates a reader / writer whose standard is different from that of the initial reader / writer.

For this reason, in this embodiment, the reader / writer mounting structure for mounting the reader / writer 11 to the front panel 3a is devised to enable mounting of the reader / writer 11 having different standards.
Specifically, in this embodiment, a reader / writer installation adapter 31 for compatibility is adopted, and the reader / writer 11 having a different standard can be attached to the reader / writer mounting opening 25.

The reader / writer mounting structure will be described with reference to FIGS. 1 to 4. First, the reader / writer mounting opening 25 is formed in the front panel 3a based on the size and shape of the reader / writer. For example, the reader / writer mounting opening 25 has a rectangular shape (FIG. 4).
Here, as shown in FIGS. 1 and 4, the outer shape of the reader / writer 11 is different from the standard, for example, the vertical dimension is larger than the reader / writer mounting opening 25, and the width dimension is for the reader / writer mounting. A block shape smaller than the opening 25 is formed. The rear end surface of the reader / writer 11 becomes an installation surface 11a. In other words, the installation surface 11a of the reader / writer 11 is the installation surface 11a with a rear surface having a size and shape different from that of the reader / writer mounting opening 25.

  More specifically, the seal member 33 is attached to the outer peripheral portion of the installation surface 11a. In addition, four boss portions 35 project from the four corners of the installation surface 11a, and screw holes 37 (reader / writer fixing seats) are formed at the tip of each boss portion 35. Incidentally, the four screw holes 37 of the reader / writer 11 have a vertical pitch larger than the vertical dimension of the reader / writer mounting opening 25 formed in the front panel 3a, and the horizontal pitch is for mounting the reader / writer. It is smaller than the horizontal dimension of the opening 25 (different from the original reader / writer).

  2 to 4, a mounting plate 39 (corresponding to the mounting member of the present application) is disposed on the back surface of the front panel 3a so as to cover the opening of the reader / writer mounting opening 25 from the back surface side. The mounting plate 39 is a component used for mounting the reader / writer 11, and includes a bracket portion 41 protruding from the back surface of the front panel 3a, a screw member 43 screwed into the bracket portion 41, and an insertion hole through which the screw member 43 is inserted. 43a is used to fix the plate surface in a posture facing the reader / writer mounting opening 25.

The reader / writer installation adapter 31 is a component arranged so as to cover the front surface of the reader / writer mounting opening 25 by using the mounting plate 39.
The reader / writer installation adapter 31 will be described. As shown in FIGS. 3 to 6, the reader / writer installation adapter 31 is made of, for example, a synthetic resin and has a cover portion 47 having a plate shape. The cover portion 47 has a shape that covers the reader / writer mounting opening 25 from the front surface of the front panel 3a, in this case, a rectangular shape. After the cover 47, the front side having a flat surface is the reader / writer mounting side, and the plate surface portion disposed on the reader / writer mounting opening 25 is the installation area α (the installation area of the present application) to which the reader / writer 11 is attached. (FIG. 5). The reverse side, on the opposite side, where the ribs 49 are formed on the outer peripheral edge is the front panel mounting side.

As shown in FIG. 4, four bosses 51 protrude from the back surface of the cover portion 47 (around the installation area α) at positions corresponding to, for example, the four corners of the reader / writer mounting opening 25. . A screw hole 53 is provided at the tip of each boss 51. Ribs 52 are formed so as to connect the boss portions 51.
The plate surface portion (cover portion) around the screw hole 53 is provided with four (plural) through-holes 55 (corresponding to the fixing hole of the present application) to be combined with the screw hole 37 (installation surface 11a) of the reader / writer 11. . Since the four through holes 55 include holes having a pitch larger than the pitch of the screw holes 53, the reader / writer 11 and the reader / writer installation adapter 31 are prevented from being fixed.

Therefore, as shown in FIG. 4, the four through holes 55 are arranged so that a part thereof is shifted outward from a region facing the opening of the reader / writer mounting opening 25.
In order to realize this arrangement, as shown in FIGS. 3 to 6, one side area of one set of the two side areas facing each other of the cover portion 47 extends longer than the other side area on the opposite side. I'm allowed. The extended area 56 is provided with at least a part of the through hole 55, here, the upper two through holes 55. The remaining two through-holes 55 are provided so as to be shifted to the plate surface portion facing the opening of the reader / writer mounting opening 25 by the amount of deviation due to the extension region 56. The reader / writer 11 is set to be disposed at a position deviated from the reader / writer mounting opening 25 by the arrangement of the through holes 55. In the present embodiment, for example, the reader / writer 11 is arranged close to the money amount display unit 9, so that the extension area 56 is arranged in the direction extending upward (upper side).

  Then, as shown in FIG. 4, when a screw member 57 (corresponding to the first fastener of the present application) is screwed into the screw hole 37 of the reader / writer 11 through the through hole 55 from the back surface side of the cover portion 47, the cover portion 47. The reader / writer 11 is fastened to the front side. That is, the reader / writer 11 and the reader / writer installation adapter 31 are fixed by a fastening structure using the through hole 55 and the screw member 57 (corresponding to the first fastening structure of the present application).

  Further, after the reader / writer 11 is fixed, the cover portion 47 is disposed so as to cover the front surface of the reader / writer mounting opening 25, and from the through hole 39a provided in the mounting plate 39 (the rear surface side of the front panel 3a), a screw member When 59 (corresponding to the second fastener of the present application) is screwed into the screw hole 53 (back surface of the cover portion 47) at the end of the boss portion 51 through the reader / writer mounting opening 25, the entire reader / writer installation adapter 31 (cover portion) 47, including the extension area 56) is fastened to the front panel 3a. That is, the reader / writer installation adapter 31 is fixed to the front panel 3a by a fastening structure using the screw hole 53 and the screw member 59 (corresponding to the first fastening structure of the present application). Incidentally, the boss portion 51 protrudes in accordance with the position of the mounting plate 39.

By such a combination of fastening structures, the reader / writer 11 is fixed to the front surface of the door body 3 via the reader / writer installation adapter 31, that is, assembled at a position offset upward from the reader / writer mounting opening 25 (fixing means of the present application). Equivalent).
Further, as shown in FIG. 4, a frame-shaped (rectangular frame) convex portion 61 that fits the opening edge of the reader / writer mounting opening 25 is formed on the back surface of the cover portion 47 (reader / writer installation adapter). Yes. The frame-shaped convex portion 61 is formed in advance corresponding to the position of the reader / writer mounting opening 25, and the frame-shaped convex portion 61 is simply fitted into the reader / writer mounting opening 25 from the front side of the door 3. Thus, the cover 47 is disposed on the front surface of the front panel 3 a so as to cover the reader / writer mounting opening 25, and at the same time, the screw hole 53 of the boss 51 is positioned in the through hole 39 a of the mounting plate 39. Of course, the frame-shaped convex portion 61 also has a function of preventing foreign matter (such as a driver tip) from entering the reader / writer mounting opening 25 from the outside. Incidentally, the frame-shaped convex portion 61 is integral with the boss portion 51 and is integrally coupled with the inner rib 52 via various ribs 64.

In addition, a rectangular seal groove 62 a that houses the seal member 62 is formed around the convex portion 61, and the seal member 62 seals the back surface of the cover portion 47 and the reader / writer mounting opening 25. (FIGS. 3 and 4).
Further, on the back surface of the cover portion 47 (reader / writer installation adapter), the adapter portion facing the reader / writer mounting opening 25, specifically, the plate surface portion surrounded by the convex portions 61 and the lattice-shaped ribs 52, A wiring insertion opening 63 through which the wirings 11b extending from the reader / writer 11 are inserted is formed (FIG. 4). Here, the wiring insertion opening 63 is arranged at a position biased to one side in the left-right direction, for example, the right side. Incidentally, a rib portion 64a is provided on the side (left side) opposite to the side biased across the wiring insertion opening 63 (both in FIG. 4).

The mounting plate 39 is formed with an opening portion 65 for guiding the wirings 11b from the wiring insertion opening 63 to a control unit (not shown) installed on the back surface of the door body 3, and the reader / writer 11 and the control unit. It is a structure that can be connected.
In addition, the rib part 14 is provided also in the back surface of the extension part 56 (FIG. 4).
Next, the operation of the reader / writer mounting structure thus configured will be described.

Now, assume that the reader / writer 11 is assembled in the reader / writer mounting opening 25 on the front surface of the door 3.
At the present stage, the reader / writer 11 has a larger vertical dimension and a smaller width dimension than the original reader / writer, so it is difficult to attach the reader / writer 11 to the reader / writer mounting opening 25 as it is.

  Therefore, assembly is performed using the reader / writer installation adapter 31. At this time, the reader / writer 11 is assembled to the reader / writer installation adapter 31. For this purpose, first, as shown in FIG. 4, the installation surface 11a of the reader / writer 11 is arranged in the installation area α (FIG. 5). Subsequently, the screw member 59 is screwed into the screw hole 37 of the reader / writer 11 through the through hole 55 from the back side of the adapter 31 for installing the reader / writer. Thus, the reader / writer 11 is fixed to the surface side of the reader / writer installation adapter 31 while being sealed by the seal member 33.

Subsequently, the reader / writer installation adapter 31 with the reader / writer 11 is assembled to the front surface of the door 3. At this time, as shown in FIG. 3 and FIG. 4, the frame-shaped convex portion 61 formed on the back surface of the reader / writer installation adapter 31 is formed on the front panel 3 a from the front surface side of the door body 3.
