2. Description of the Related Art As is well known, in a communication device which is sometimes used in a so-called vertical orientation (for example, a desk phone combined with a wall), a wall hook which can be hooked into a recess of a handset is provided on the communication device body. When the communication device body is used in a vertical orientation, the recess of the handset may be used by hanging it on the wall hook, but if the wall hanging hook is also left horizontally, the wall hook becomes Inadvertently caught in the recess, the handset may be dropped.

[0003] For this reason, conventionally, the above-mentioned wall hanging hook is formed separately from the communication device housing, and a mounting groove through which the wall hanging hook can be inserted and removed is formed in the communication device housing. A structure in which elastic claws for preventing falling off are provided is disclosed in Japanese Utility Model Publication No. 3-9410 (Japanese Utility Model Publication No. Sho 61-57736).
Has been proposed. In other words, in this communication device housing structure, the wall hanging hook is replaced with the communication device main body depending on the use direction of the communication device main body, so that the wall hanging hook is used only when the communication device is used by hanging on the wall. The function is exhibited.

[0004]

However, even with such a replacement wall hook, there is a problem that noise is generated in recent communication devices. That is, in recent communication devices, a speaker is built in the communication device body,
In many cases, the received sound is loudspeaked by this speaker, so if a slight vibration occurs in the communication equipment housing due to the output of the speaker, a lightweight wall hook not sufficiently restrained to the communication equipment housing. Vibrates, causing "chattering". Also, the conventional wall hook is a flat plate
Since it is manufactured as a product, it can be easily replaced by the user.
And difficult to use, you must be a person who is used to handling communication equipment
For example, there is a problem that the replacement operation cannot be easily performed.

An object of the present invention is to take advantage of the advantage of a structure in which a wall hook can be replaced according to the direction of use, taking into account the current state of the housing structure of a conventional communication device as described above. Even if vibration is applied to the equipment housing, no vibration noise is generated from the wall-mounted hook , and any tool can be used.
Users can easily replace the wall hook without having to
Another object of the present invention is to obtain a housing structure of a communication device that can perform the above.

[0006]

In order to achieve this object, the present invention provides a receiving unit of a handset, in which a mounting groove formed facing a dent for a receiver formed on a panel surface of a communication device housing is formed. In a housing structure of a communication device in which a detachable wall hanging hook having a hook piece to be hooked in a recess is inserted and locked in the mounting groove, a pair of finger hooks having a substantially triangular cross section having the hook piece on one side is formed on both sides. The connecting portion of the wall hanging hook is slidably positioned in the mounting groove, and an elastic claw is integrally formed on one of a pair of guide walls of the communication device housing forming the mounting groove, and the connecting portion of the connecting portion is formed. The two-dimensional projection that engages with the locking groove on the side surface and urges the wall hook in a plane parallel to the panel surface, and attaches the wall hook in the thickness direction by contacting the finger hook opposing surface of the wall hook. Thickness projections Serial proposes a chassis structure of a communication device which is integrally formed at the tip portion of the elastic claw.

That is, in FIGS. 2 and 4, a pair of guide walls 10L and 10R opposed to each other in the left-right direction of FIG. 2 are located inside the border formed on the panel surface 1a. , 10R, there is formed a mounting groove 9 which is extended in the up-down direction of FIG. Right guide wall 10R groove side 10a
The upper surface 10b serves as a positioning reference surface for a wall hook 8 to be described later, and the surface of the left guide wall 10L, 10R has an elastic claw 11 whose tip can be deformed in the left-right direction and the direction perpendicular to the plane of FIG. Are integrally formed.

As shown in FIG. 4, the wall hook 8 which can be inserted and removed along the guide walls 10L and 10R is provided with a pair of finger hooks 8a and 8b having a triangular cross section to which a fingertip can be hooked. is are connected by the mounting said width dimension L ₁ which corresponds to the groove 9 guide wall 10L, connecting portion 8c of the thickness L ₂ corresponding to the thickness of the 10R. Also,
A locking groove 12 is formed on the side surface of the connecting portion 8c facing the elastic claw 11, and as can be understood from FIGS. The arc-shaped two-dimensional projection 11a at the tip can be pressed. On the other hand, as understood from FIG. 4, the tip of the elastic claw 11 has an arc-shaped thickness projection 11b protruding on the opposite side to the panel surface 1a. 8 can be pressed against the opposing surfaces 8d of the finger hooks 8a and 8b.

A hook piece 8e that can be inserted into the receiving section recess 5a formed in the handset 5 is integrally formed at one end of the finger hook 8a, so that when the telephone housing 1 is used by hanging it on a wall. When the wall hanging hook 8 is mounted in the mounting groove 9 in the direction shown in FIG. 5, the hook piece 8e of the wall hanging hook 8 prevents the handset 5 from falling off the telephone housing 1.
