Description

  The present invention relates to a component mounting structure for mounting components having terminals, switches, and the like for connecting external devices to a panel member installed behind and above a keyboard in a keyboard device.

  As an electronic keyboard device (keyboard device) including an electronic piano and an electronic organ, for example, as shown in Patent Document 1, there is one in which a panel member is installed on an upper part on the rear side of a keyboard. The panel member has, for example, an upper wall that covers an upper part on the rear side of the keyboard, and a front wall (standing wall) that extends downward from the front end of the upper wall and is erected along the rear end of the keyboard. It is formed in an L shape. In the keyboard device having such a panel member, a terminal (hereinafter referred to as “USB terminal”) for connecting a device capable of transferring data by USB (Universal Serial Bus) and an external audio device are connected. Parts having an audio terminal, a power switch, a keyboard split switch, a portamento bar, etc. may be installed. In addition to the front wall of the panel member, these parts may be provided at various positions such as the lower side of the front edge of the keyboard, the upper surface of the timepiece section or the front side thereof, or the back side of the keyboard device body. Considering the operability at the time, it is desirable to provide it on the front wall of the panel member.

  By the way, as a panel member provided in a conventional keyboard device, a wooden product or a molded product of a synthetic resin has been mainstream. On the other hand, recently, an extrusion-molded product such as aluminum is sometimes used for the panel member in order to give a high-quality appearance to the keyboard device and to increase the rigidity. However, extruded products such as aluminum are formed thinner than wood. Thus, during extrusion molding, a uniform protrusion (rail portion) protruding in the extrusion direction is formed at the same time to prevent twisting and bending of the plate surface. Furthermore, using this rail part, other parts are fixed to the panel member (for example, fixed with a threaded screw between two protrusions). However, since the rail portion is originally formed for reinforcing the panel member, it is not necessarily suitable for fixing other components. For this reason, in a normal fixing method, the degree of freedom of fixing becomes low compared to fixing to a panel member made of a synthetic resin molded product or the like. Moreover, since the panel member which consists of extrusion molding products is thin, when fixing tools, such as a screw, are fixed to locations other than a rail part, it will become easy for a fixing tool to penetrate a panel board and to protrude on the surface side. This is dangerous as well as affecting the appearance of the panel member. Further, the screw hole penetrating the thin plate is likely to be retracted, and there is a possibility that secure fixing of the screw cannot be ensured.

  In addition, there is a panel member of a keyboard device made of a conventional extrusion-molded product in which the rail portion as described above is formed on the lower surface side of the upper wall. However, if the rail part consisting of the protrusions is located in the vicinity of the front wall, when trying to fix the above parts to the front wall, the parts will interfere with the rail part with the normal fixing means, so the desired part There is also a problem that parts cannot be fixed in position or space.

  In order to cope with such problems, the main unit side of the keyboard device installed inside the panel member is not fixed to the panel member, such as a board on which a terminal for connecting an external device or a switch is mounted. It is also conceivable to fix to. However, in that case, it is necessary to expose the terminal and the switch from the opening provided in the panel member, and the positioning of the component with respect to the panel member must be performed accurately. Therefore, there is a problem that it is necessary to increase the dimensional accuracy of the panel member, and the keyboard device is complicated to assemble.

  Therefore, in order to increase the efficiency of the manufacturing process of the keyboard device, when fixing the above parts to the panel member made of an extrusion molded product, the positioning and fixing of the parts with respect to the panel member can be performed as easily and reliably as possible. It is desirable to make it.

It was made to install in a state where the part was exposed to the front side of the front wall from the penetration part. As a result, parts can be arranged on the front wall using the rail portion formed on the upper wall of the panel member that is an extrusion molded product, so even when the rail portion protrudes in the vicinity of the front wall, the desired front wall is desired. It is possible to place a component of a desired size at the position.

  In addition, since the parts are attached to the panel member using the rail part, even if the front wall or upper wall of the panel member is a thin plate, the parts can be attached without exposing screws or other fixtures on the surface side. Can be done. Therefore, the appearance of the keyboard device can be improved. Furthermore, by providing the mounting member, it is possible to easily and reliably mount even a part having a shape or structure that is difficult to be directly mounted on the rail portion. Further, since the components are attached to the panel member side instead of the main body portion side of the keyboard device, the components can be attached at an accurate position without strictly positioning the components when the panel member is assembled to the keyboard device. It becomes like this. Therefore, it is possible to facilitate the processing process of the panel member and increase the efficiency of the assembly process of the keyboard device.

Has been made. Therefore, the USB board 43 can be more securely fixed to the first and second rail portions 23 and 26 while having a simple fixing structure using the gap 26a between the adjacent protrusions 27 and 28. Become.

  Moreover, in this embodiment, the 1st fixing screw 51 and the 2nd fixing screw 52 are fastened in the direction where a mutual axial direction orthogonally crosses. Therefore, since the mounting angle 45 can be fixed from a plurality of directions by the first fixing screw 51 and the second fixing screw 52, the positioning and fixing of the mounting angle 45 with respect to the front panel 20 becomes more reliable.

  In the component mounting structure described above, the terminal cover 42 attached to the opening 29 of the front wall 22 is fixed to the mounting angle 45 from the front side of the front wall 22 through the opening 29. As a result, the terminal cover 42 can be reliably fixed with a simple structure. In particular, if the terminal cover 42 is to be directly fixed to the front wall 22 of the front panel 20 made of an extruded aluminum product, a fixing tool such as a screw is likely to be exposed to the front side, so that there is a limit to fixing the terminal cover 42. Although it may occur, in the component mounting structure of the present embodiment, the terminal cover 42 is fixed to the mounting angle 45 instead of the front wall 22, so the degree of freedom in fixing the terminal cover 42 can be increased.
