The first and second substrates 112 and 114 are formed substantially symmetrically with the bent portion 116 as the axis of symmetry. The first and second substrates 112 and 114 are bent at the bent portion 116 and face each other. That is, the substrate body 78 is formed in two layers as shown in FIG. The substrate body 78 has a path for transmitting a signal bidirectionally between the first and second substrates 112 and 114 by a signal circuit (not shown).

  As shown in FIGS. 5A and 5B, the first and second substrate surfaces 112a and 112b of the first substrate 112 have a plurality of contacts 122 that electrically connect the connection member 76. It is arranged in a penetrating state. These contact points 122 are arranged such that a part of the other end of the single pin contact point 76b of the connecting member 76 is penetrated. The contact 122 of the first substrate 112 and the end portion of the single pin contact 76b of the connecting member 76 are fixed by solder. Therefore, the contact 122 of the first substrate 112 and the single pin contact 76b of the connection member 76 are electrically connected.

  As shown in FIGS. 5A and 5B, the second substrate 114 is provided with an amplifier circuit 128 to which the single pin contact 76b of the connection member 76 is electrically connected. As shown in FIG. 5B, a connector 132 and a land portion 134 are further provided on the second substrate surface 114 b of the second substrate 114. These connectors 132 are formed of a material such as polyphenylene sulfide (PPS) that is prevented from being deteriorated even if high-pressure steam sterilization is performed.

  The land portion 134 is disposed on the outer peripheral side of the substrate surface 114b of the second substrate 114, and is located near the land portion X (see FIG. 5B) outside the shield contact 76a on the substrate surface 112a shown in FIG. Is arranged. A connector 132 that is electrically connected to the amplifier circuit 128 is attached to the substrate surface 114 b of the second substrate 114. That is, the connector 132 and the connection member 76 are electrically connected.

  A conductive member 136 is disposed between the first and second substrates 112 and 114. One end of the conductive member 136 is soldered to a land portion X that connects the shield contact 76 a and the substrate 112. The other end of the conductive member 136 is connected to a land portion 134 provided on the substrate surface 114 b of the second substrate 114. When the conductive member 136 is connected to the substrate surface 114a of the second substrate 114 and the substrate surface 112a of the first substrate 112, the edge portion of the substrate surface 114b of the second substrate 114 as shown in FIG. It is disposed on the first substrate 112 side through the recess 114c.

The cable line substrate 138 is electrically connected to an end portion of a signal wire (cable line) 36 extending from the insertion portion 22 and the operation portion 24 side of the endoscope 12 through the universal cable 26.

  The cable line substrate 138 is inserted in a direction orthogonal to the second substrate surface 114 b of the second substrate 114. For this reason, the cable wire board 138 can be given a stronger holding force to the connector 132 than to be inserted in parallel to the second board 114.

  Further, the cable board 138 is provided with a reinforcing plate 140 having an appropriate thickness. For this reason, the holding force for holding the cable board 138 with respect to the connector 132 can be further increased.

  When an electrical signal is transmitted to the connecting member 76 electrically connected to the CCU 16, electrical radiation noise is not transmitted from the second board 114 on which the connector 132 is mounted to the first board 112 through the signal path. The electrical radiation noise is transmitted through the conductive member 136 to the shield contact 76a through a short signal path.

  One end of a conductive member 136 is connected to the terminal portion of the shield contact 76a. Further, the land portion 134 of the second substrate 114 is connected to the other end of the conductive member 136. For this reason, the first and second substrates 112 and 114 are connected by the conductive member 136 without using an assembly member such as a noise countermeasure component for a signal that generates electrical radiation noise (EMC noise). Since the signal path between the first and second substrates 112 and 114 is short, the generation of electric radiation noise is suppressed.

  Next, display of products on the electrical connector 28 of the endoscope 12 and display labels for alerting will be described with reference to FIGS.

  As shown in FIG. 7, a display label 210 is affixed to the electrical connector main body 52. The display label 210 is appropriately provided with characters and symbols for product display and alerting to inform the operator of the endoscope 12 of the contents. The display label 210 has a hole 210a that avoids the gate portion of the electrical connector main body 52 that is a molded member.

  The display label 210 shown in FIG. 7 is formed in the layer structure shown in FIG. For the outer surface of the display label 210, a film 212 such as a polyimide film is used as a resin material having heat resistance and weather resistance such as heat and steam so that it can withstand high pressure steam sterilization. On the lower side (inside side) of the film 212, an ink portion 214 on which display contents are printed is arranged. A double-sided adhesive tape portion 216 for adhering to the electrical connector main body 52 is disposed below the ink portion 214. A release paper 220 is attached to the adhesive surface of the double-sided adhesive tape portion 216 before being attached to the connector main body 52.

  With such a layer structure of the display label 210, the display label 210 is protected by the film 212 under high-pressure steam sterilization, and the ink part 214 and the double-sided adhesive tape part 216 on which display contents are printed are deteriorated by heat and steam. Is prevented. For this reason, the display label 210 is prevented from dropping from the connector main body 52.

  As described above, according to the endoscope system 10 according to this embodiment, the following can be said.

  By shortening the signal path in the board within the electrical connector 28 of the endoscope 12, the generation of electrical radiation noise can be suppressed. For this reason, the influence of the electric radiation noise is prevented without adding an electric radiation noise countermeasure component to the electric connector 28 of the endoscope 12, that is, without adding an EMC noise countermeasure component to the endoscope 12. be able to.

  Further, since the display label 210 is affixed to the electrical connector 28 while avoiding uneven portions without being peeled off or dropped even under high pressure steam sterilization, the display label 210 is prevented from floating or peeling, that is, falling off. can do.

  Next, a second embodiment will be described with reference to FIGS. This embodiment is a modification of the first embodiment, and members having the same structure or the same action as the members described in the first embodiment are denoted by the same reference numerals and are detailed. Description is omitted.

  FIG. 9 shows a display label 210 that is a modification of the display label 210 described in the first embodiment. The layer structure of the display label 210 according to this embodiment is the same as that of the display label 210 described in the first embodiment.

  The display labels 210 according to this embodiment are formed in a pair and are affixed in parallel. As shown in FIG. 10, the display label 210 is attached to the release paper 242 before being attached to the electrical connector main body 52. The display label 210 includes a display surface 246 and a dividing unit 248. The dividing portion 248 is formed at the center portion of the display surface 246. For this reason, the display surface 246 is divided into two. For this reason, when the display label 210 is affixed to the electrical connector main body 52, which is a mold member, by the dividing portion 248 of the display surface 246, a parting line or protrusion when the mold is released, which is generated when a mold part is created. The display label 210 is affixed while avoiding the above.

  As shown in FIG. 10, the release paper 242 is also divided into the upper release paper 242a and the lower release paper 242b by the dividing unit 244. For this reason, the release paper 242 is divided and peeled up and down.

  The dividing portion 248 at the center of the display surface 246 and the dividing portion 244 provided on the release paper 242 are orthogonal to each other, the display surface 246 is arranged on the left and right, and the release paper 242 is arranged on the top and bottom. For this reason, when the upper release paper 242a is peeled off, the back surface adhesive tape portion 216 (see FIG. 8) of the display surface 246 attaches the adhesive tape portion 216 to the electrical connector main body 52 only in the upper half.

  At this time, the display surface 246 is divided by the dividing unit 248, but since the lower release paper 242b is not peeled off, the display surface 246 is attached to the electrical connector main body 52 without being separated.

  Further, since the display surfaces 246 are not yet separated, the pair of display surfaces 246 do not shift. After the upper half of the display surface 246 is attached to the electrical connector, the lower release paper 242b is peeled off and the lower half of the display surface 246 is attached.

  Since the upper half of the display surface 246 has already been attached to the electrical connector main body 52, positioning has been completed, and when the lower half of the display surface 246 is pasted, the display surface 246 is pasted without shifting as a pair. It is done. As a result, when the display label 210 having the two separated display surfaces 246 is attached, the display labels 210 can be attached in pairs without performing troublesome operations such as positioning up and down and left and right.

  Although several embodiments have been specifically described so far with reference to the drawings, the present invention is not limited to the above-described embodiments, and all the embodiments performed without departing from the scope of the invention are described.
