Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an external storage element receiving device for an electronic musical instrument, etc., which enables the use of an external storage element such as a memory pack.

BACKGROUND OF THE INVENTION In recent years, many electronic musical instruments are equipped with an external storage element receiving device in order to store performance information and the like in an external storage element such as a compact memory pack.

An example of a conventional external storage element receiving device will be described below with reference to the drawings.

FIG. 4 shows a cross-sectional view of a conventional external storage element receiving device. In Figure 4, 1 is the main body, 2 is the insertion port provided in the main body 1, 3 is a fulcrum provided in the main body 1 along one wall of the insertion port 2, and 4 is inserted into the periphery of the insertion port 2. Ribs provided along the opening 2; 5 is a movable lid that is rotatable in the insertion direction with the fulcrum 3 as the center of rotation; 6 is a movable lid that always urges the movable lid 5 in the opposite direction to the insertion direction; A spring attached to the movable lid 5, 7 a bottom plate attached to the bottom of the main body 1, 8 a connector mounting boss attached to the bottom plate 7, 9 located below the insertion slot 2, This is a connector that is fixed to a connector mounting boss 8 via a printed wiring board base 10 with connector mounting screws 11 in order to achieve a specific connection.

The operation of the external storage element receiving device configured as above will be described below.

First, when inserting the external storage element 12 into the insertion port 2 of the main body 1 and electrically coupling it to the connector 9 below,
The movable lid 5 rotates around the fulcrum 3 in an arc in the direction of arrow A while being pushed by the external storage element 12. When the external storage element 12 is removed, the movable lid 5 is rotated to the normal position of the insertion port 2 by the restoring force of the spring 6 and returned to its original state.

Problems to be Solved by the Invention However, in the above configuration, when the external storage element 12 is inserted into the insertion slot 2, a gap is created between the external storage element 12 and the outer wall of the insertion slot 2, and the external storage element When the entire receiving device is used in a place where it is necessary to isolate it from outside air, such as inside a closed speaker, air circulation occurs through the gap.
This has had problems such as deteriorating the acoustic characteristics of the closed speaker and producing abnormal noise when air flows.

In view of the above drawbacks, the present invention provides an external storage element receiving device that blocks air flow between the inside and outside of the main body 1 even when the external storage element 12 is inserted into the insertion opening 2.

Means for Solving the Problems In order to solve the above problems, the external storage element receiving device of the present invention has a groove on the top surface so as to fit with a rib provided inside the periphery of the insertion opening, and a connector is attached. The device has a structure in which a case with a connector mounting bracket attached thereto is fixed to the main body.

Effects With the above-described configuration, the present invention blocks air circulation between the inside and outside of the case even when an external storage element is inserted into the insertion slot, so air does not flow out to the outside of the main body and the device is sealed. There will be no adverse effect on the acoustic characteristics of the type speaker.

Embodiment An external storage element receiving device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a sectional view of an external storage element receiving device according to an embodiment of the present invention.

1 is the main body, 2 is the insertion port, 3 is the fulcrum, 4 is the rib, 5 is the movable lid, 6 is the spring, 7 is the bottom plate, 9 is the connector, 10 is the printed wiring board base, 11 is the connector mounting screw, 12 is an external storage element, and the above structure is the same as the conventional structure. 13 has a groove around the top surface to fit with the rib 4, and a case mounting screw 1
A case 5 is fixed to the main body 1, and a connector mounting fitting 14 is used to fix the connector 9 to the case 13.

The operation of the external storage element receiving device configured as described above is also the same as that of the conventional example, but the case 13, which has a groove around the top surface to fit into the rib 4, is fixed to the main body 1, and the connector is connected to the case 13. By attaching the connector 9 to the case 13 from the conventional bottom plate 7 via the attachment fittings 14, air circulation can be blocked between the inside and the outside of the case 13.

In addition, in the embodiment, the connector mounting bracket 14
Although the connector 9 is attached to the case 13 through the connector 9, the connector 9 may be attached to a case having a bottom surface to which the connector 9 can be directly attached.

Effects of the invention As described above, the present invention fixes a case with a groove around the top surface to fit into the ribs of the main body to the main body, and attaches the connector from the bottom plate to the case via the connector mounting bracket. Therefore, even when the external storage element is inserted into the insertion slot,
Because air circulation is blocked between the inside and outside of the case,
Air will no longer flow out of the main body, and will no longer have an adverse effect on the acoustic characteristics of the closed speaker.

Furthermore, by attaching the connector to the main body side from the bottom plate through the case, there is no variation in the positioning dimensions between the insertion port and the connector, so the external storage element can be inserted into the connector reliably.
