  At this time, referring to FIG. 10 and FIG. 7, the support portion 24 of the lid member 2 moves in the notch portion 15 c of the inner protrusion portion 15 a of the case body 1. The support part 24 of the lid member 2 reaches the region R3 from the region R1 through the region R2 by moving to open the lid member 2. Since the region R3 is formed in an arc shape, the movement of the support portion 24 is restricted and the movement of the lid member 2 is stopped. That is, the lid member 2 stops when the support portion 24 stops at the end of the notch 15c. As described above, the support portion 24 abuts on the notch portion 15c, thereby preventing the lid member 2 from being moved too much and the torsion spring 3 from being damaged.

  FIG. 11 is a side view showing a state in the middle of opening the lid member. As shown by the arrow 76, the lid member 2 can be opened by tilting the cover 23. At this time, the locking portion 23a of the cover portion 23 and the contact portion 15d of the inner projection 15a of the case body 1 may contact each other. When the contact portion 15d is formed so that its height gradually increases toward the rotation axis when viewed from the side, the contact portion 15d of the inner projection portion 15a also contacts. The lid member 2 can be opened smoothly. Further, due to the elasticity of the torsion spring 3, as shown by an arrow 79, the lid member 2 is biased toward the side where the rotation shaft is disposed. For this reason, the lid member 2 can be easily opened. The support part 24 of the lid member 2 moves from the region R3 of the notch 15c formed in the inner protrusion 15a of the case body 1 toward the region R1 (see FIG. 7).

  Moreover, in this Embodiment, the latching | locking part 23a of the cover part 23 and the contact part 15e of the outer side protrusion part 15b of the case main body 1 may contact | abut. Since the contact portion 15e gradually becomes lower than the contact portion 15d when viewed from the side, the lid member 2 is opened, and the locking portion 23a and the contact portion 15e of the lid member 2 are Contactless. The contact portion for contacting the cover portion of the lid member is not limited to this form. For example, the side surface shape of the contact portion 15d and the side surface shape of the contact portion 15e are formed to be substantially the same. It does not matter. Moreover, in this Embodiment, although it has two contact parts, it is not restricted to this form, One contact part and three or more contact parts may be formed.

  In FIG. 13, the enlarged side view of the part of the rotating shaft when the opening operation of the cover member 2 is continued is shown. In the present embodiment, a straight line connecting the tip portions of the torsion springs becomes the rotation axis. The center of the insertion hole 25 is arranged at a position shifted from the center point 24 a of the support portion 24 of the lid member 2. The torsion spring 3 urges the lid member 2 in a direction perpendicular to the extending direction of the extending portion 32 as indicated by an arrow 77. At this time, a force is applied to the insertion hole 25 in the direction in which the lid member 2 opens, so that the lid member can be easily opened.

  FIG. 12 shows a side view when the lid member is completely opened. The support part 24 of the lid member 2 is in contact with the region R1 of the notch 15c formed in the inner protrusion 15a of the case body 1 (see FIG. 7). The lid member 2 is disposed downward, and is maintained in a completely open state by gravity and the elasticity of the biasing means. For this reason, when adjusting the electronic device main body arranged inside the housing case, it is not necessary to hold the lid member with one hand, and the work efficiency of adjusting the electronic device main body is improved.

  Furthermore, by increasing the elasticity of the torsion spring, or by disposing the rotation shaft away from the center of the support portion of the lid member, the lid member and the case main body can be positioned regardless of the orientation in which the storage case is arranged. The lid member can be completely opened only by releasing the fitting. For example, even when the housing case of an electronic device is fixed to a horizontal fixed surface, the lid member is completely released when the hand is released simply by releasing the fitting of the lid member by strengthening the elasticity of the torsion spring. It can be in the open state.

  Referring to FIG. 11, when closing lid member 2, as shown by arrow 78, the end of lid member 2 opposite to the rotation shaft is pushed toward case body 1. The lid member 2 can be smoothly closed by sliding the contact portion 15d of the inner projection 15a of the case body 1 and the tip of the locking portion 23a of the lid member 2. Referring to FIG. 9, the lid member 2 is fixed to the case body 1 by fitting the end portion of the case body 1 and the cover portion 23 of the lid member 2.

  When the closing operation of the lid member is incomplete, for example, as shown in FIG. 11, the lid member is largely opened by the elasticity of the torsion spring 3. By forming the inclined contact portion 15d of the inner projecting portion 15a of the case body 1, the lid member can be largely opened.

  Alternatively, when the closing operation of the lid member is incomplete, the lid member can be completely opened by the action of at least one of the elasticity of the torsion spring and the gravity. For this reason, when the lid member is not completely closed, it can be easily visually recognized.

  The housing case of the electronic device in this embodiment can open and close the lid member by a series of operations. For this reason, the lid member can be easily opened and closed when adjusting or repairing the electronic device in a place where the scaffolding on the roof is bad or in a narrow space such as the attic.

  In the housing case of the electronic device according to the present embodiment, the pivot shaft of the lid member is arranged at the lower part of the housing case when attached to the mounted member. Further, the rotation axis is formed so as to be substantially parallel to the horizontal direction. For this reason, when the engagement between the lid member and the case main body is released, the lid member can be easily opened by the action of gravity without applying a large force.

  In addition, when the pivot shaft of the lid member is arranged at the upper part of the housing case, it is necessary to form means for fixing the lid member such as a locking claw at the lower part. For this reason, for example, in an electronic apparatus having an F-type connector, it is necessary to arrange such a fixing means on the front side of the F-type connector protruding downward, and the front side portion of the F-type connector is hidden. End up. In the present embodiment, means for fixing the lid member on the upper side is arranged by arranging the rotation shaft on the lower side. For this reason, when the lid member is closed, the lower end portion is largely opened, and workability is improved.

  The electronic device storage case in the present embodiment has a rotating shaft disposed in the lower part when attached to the member to be attached. However, the electronic device storage case is not limited to this form, and the electronic device storage case can be used in any state. It can be attached to a member to be attached. For example, the housing case for the electronic device according to the present invention may be attached to the horizontal surface of the member to be attached.

  The case main body and the lid member of the housing case in the present embodiment can be formed of any material. As the material of the case body and the lid member, for example, ABS (acrylonitrile butadiene styrene) resin, AES (acrylonitrile / ethylene propylene rubber / styrene) resin and the like are preferable because of light weight. Further, in the case of a housing case for an electronic device arranged outdoors, it is preferable that these resins and the like contain a weather resistant material.

  In FIG. 14, the side view of the storage case of an electronic device provided with the other urging | biasing means in this Embodiment is shown. Other urging means in the present embodiment includes a winding spring 4. The winding spring 4 has a coil portion 42 wound so that the planar shape is circular. The winding spring 4 has a fastening part 41 extending from the coil part 42. The fastening portion 41 is formed in a U shape in a planar shape. The fastening portion 41 is fixed to the side wall of the case main body 1 by screws 45.

  The winding spring 4 has a linear extending portion 43 extending from the coil portion 42. The winding spring 4 has a tip portion extending from the extending portion 43, and the tip portion is inserted into the insertion hole 25 of the lid member 2. The winding spring 4 is formed so that the extending portion 43 is positioned at the open position 62 when the tip portion is not disposed in the insertion hole 25. The winding spring 4 is formed so as to urge the lid member 2 toward the side where the rotation shaft is disposed, as indicated by an arrow 74. The opening / closing operation is the same as that of the housing case of the electronic device including the torsion spring.

  By including a winding spring as the biasing means, the biasing force applied to the lid member can be easily adjusted. For example, the elasticity of the urging means can be easily changed by changing the number of turns of the coil portion.

  The biasing means in the present embodiment includes a torsion spring or a winding spring. However, the biasing means is not limited to this form, and the biasing means is formed so as to bias the lid member toward the rotating shaft. It doesn't matter if it is. For example, the extension part of the torsion spring in the present embodiment may be formed to have elasticity by being bent.

  The torsion spring and the winding spring in the present embodiment are formed of metal wires. The material of the urging means is not limited to this form, and any member can be used. When the electronic device is disposed outdoors, a highly dustproof or weatherproof material is preferable.

  The amplifier in the present embodiment includes the above-described housing case. The case main body is formed such that an F-type connector as a connector is exposed downward, and a rotation shaft is disposed at the lower part. Since the amplifier in the present embodiment does not have a portion for fixing the lid member on the lower side where the F-type connector is disposed, the front side of the F-type connector can be greatly opened. A connector such as an F-type connector can be connected to a cable with the lid member closed. Therefore, the cable can be easily connected to the connector with the lid member closed, and the working efficiency is improved. Adjustment of the electronic device body can be performed by opening the lid member after connecting the cable to the connector.

  In the present embodiment, the amplifier attached to the antenna device has been described as an example. However, the present invention is not limited to this embodiment, and any device can be adopted as the electronic device. For example, the electronic device may be a mixer, a distributor, a filter, or the like.
