  The cable guide 10 shown in FIGS. 1A, 1B, and 1C includes a plurality of holders 11 and a shield material 12.

  As will be described in detail later, the plurality of holders 11 hold the cable 100 that is curved by being rotatably connected. For example, the holder 11 has a rectangular tube shape. The holder 11 may be openable so that the cable 100 can be inserted.

  For example, the cable 100 is disposed between a housing of an automatic transaction apparatus such as an automatic teller machine and a unit drawn from the housing. However, the cable guide 10 can naturally be used in applications other than the automatic transaction apparatus and in an arrangement place other than between the housing and the unit drawn from the housing.

  As shown in FIG.2 and FIG.3, the holder 11 contains the rotating shaft part 11a and the rotating shaft insertion hole 11b. For example, the holder 11 is formed from a non-conductive material such as plastic, but may be formed from a conductive material.

  A total of two rotation shaft portions 11 a are provided on the upper and lower sides on one end side in the connecting direction (arrow D) of the holder 11. The rotating shaft part 11a provided on the upper part of the holder 11 protrudes upward. The rotating shaft part 11a provided in the lower part of the holder 11 protrudes downward.

  A total of two rotation shaft insertion holes 11b are provided on the other end side in the connecting direction of the holder 11 (arrow D).

  As shown in FIG. 2, the rotating shaft portion 11a is inserted into the rotating shaft insertion hole 11b so as to be rotatable (arrow R), so that the plurality of holders 11 are connected in a straight line so as to be rotatable with respect to each other. . Thereby, the some holder 11 can be bent along the cable 100 which curves.

  The shield material 12 shown in FIGS. 4A, 4B, and 4C extends over the plurality of holders 11 and is arranged inside the plurality of holders 11 so as to be capable of being bent. Although only one shield material 12 is arranged, a plurality of shield materials 12 extending across the plurality of holders 11 may be arranged separately.

  As shown in FIGS. 5, 6, and 7, the shield material 12 includes a central portion 12 a, a protruding portion 12 b, and an opening 12 c. For example, the shield material 12 is formed of a material that exhibits electromagnetic shielding properties such as a metal material. The shield material 12 has a sheet shape. The shield material 12 is preferably along the inner peripheral surface of the holder 11. The shield material 12 may be used in a necessary length by cutting out according to the number (length) to which the holder 11 is connected. The shield material 12 may be attached to another member.

As shown in FIG. 5, the central portion 12a extends in the connecting direction (arrow D) and has a strip shape.
The protruding portion 12b protrudes from the central portion 12a to both sides in the width direction of the shield material 12 (direction intersecting the connecting direction D). For example, the protruding portion 12b has a quadrangular shape. The protruding portions 12b on both sides may be provided at intervals at which the plurality of holders 11 are connected.

The opening 12c is formed across the central portion 12a and the protruding portions 12b on both sides.
The protruding portions 12b on both sides are bent so as to face each other at the first bent portion F11 located at the end portion on the central portion 12a side. For example, in this embodiment and second and third embodiments described later, the bending angle is 90 degrees. However, the bending angle may be an angle other than 90 degrees, and the bent portion may be rounded.

  The first bent portion F11 is desirably a boundary portion with the central portion 12a in the protruding portion 12b. However, the end portion of the protruding portion 12b on the central portion 12a side where the first bent portion F11 is located is slightly spaced from the central portion 12a (for example, one of the protruding portions 12b in the width direction of the shield material 12). A portion with a portion (for example, 1/10 or less of the length of the protruding portion 12b) is also included.

  Further, the protruding portions 12b on both sides are bent so as to approach each other at the second bent portions F12 located at both ends in the width direction of the shield material 12 in the opening 12c. The second bent portion F12 is desirably located at both ends of the opening 12c in the width direction of the shield material 12, but may be located within the opening 12c or slightly spaced from the opening 12c. It may be located in the part.

  In the present embodiment, the shield member 12 includes a belt-like central portion 12a extending in the connecting direction (arrow D) of the holder 11, and both sides in the width direction intersecting the connecting direction (arrow D) from the central portion 12a. And a projecting portion 12b projecting to the center portion 12a and an opening 12c formed across the projecting portion 12b on the center portion 12a and both sides. Further, the protruding portions 12b on both sides are bent so as to face each other at the first bent portion F11 located at the end portion on the central portion 12a side. Therefore, the shield material 12 can be curved and exhibit electromagnetic shielding properties with a simple configuration. Further, the cable 100 can be inserted into the shield member 12 from the direction intersecting the connecting direction (arrow D).

  Furthermore, in the present embodiment, the protruding portions 12b on both sides are bent so as to approach each other at the second bent portions F12 located at both ends in the width direction of the shield material 12 in the opening 12c. Therefore, the shield material 12 is in a state of surrounding the cable 100 as compared with the case where only the first bent portion F11 is provided, and can further exhibit electromagnetic shielding properties.

  Moreover, in this embodiment, the protrusion part 12b of both sides is provided in the space | interval where the several holder 11 is connected. Therefore, it can be bent similarly to the holder 11.

  In the present embodiment, the shield material 12 has a sheet shape. Therefore, electromagnetic shielding properties can be exhibited with a simple configuration. Further, since the shield material 12 can be manufactured in a single sheet shape, it can be easily manufactured and the manufacturing cost can be reduced. Furthermore, by making the shield material 12 a separate part from the holder 11, the existing holder 11 can be easily attached and detached, and the range of usage is expanded.
