2. Description of the Related Art The slide operating device having the above-mentioned structure has been widely used in various electric devices. FIG.
Shows an example of a conventional slide operating device,
(A) is a perspective view showing a slide operation member of a conventional slide operation device of the above example alone, (B) is a plan view of the slide operation member of (A), and (C) is a conventional example of the above example. It is a side view which shows the slide operating member of (A) combined with the guide member for slide guides of the slide operating device of (D), and (D) is a cross-sectional view taken along the line CC of (C). .

As shown in FIG. 1 (C), a slide operating member 10 of an example of a conventional slide operating device has a horizontally elongated, substantially rectangular cross section as shown in FIG. A main plate 10a having a flat and substantially square flat surface is placed on the upper surface of the sliding guide member 12. The sliding guide member 12 is provided on an exterior body (not shown) of an electric device using the slide operating device, extends in the sliding direction of the slide operating member 10, and has a central portion in the width direction on the upper surface thereof. A friction reducing groove 12a extending in the sliding direction is formed so as to reduce frictional resistance generated between the slide operating member 10 and the main plate 10a.

A knob 10b for operating the slide operating member 10 is formed at the center of the upper surface of the main plate 10a.
On the lower surface of the main plate 10a, one side surface located in the width direction of the slide guide member 12 is located outwardly below two positions spaced apart from each other by a predetermined distance in the extending direction of the slide guide member 12. Pair of first clamping arms 10 projecting toward
c and 10d are formed, and on the lower surface of the main plate 10a, a pair of first guides is provided in the extending direction of the slide guide guide member 12 outside the other side surface in the width direction of the slide guide guide member 12. One second holding arm 10e protruding downward is formed at a position corresponding to approximately the middle of the first holding arm 10c, 10d.

The pair of first holding arms 10c and 10d and the second holding arm 10e are slid in the extending direction of the slide guide member 12 as shown particularly in FIG. 1C. Sliding operation member 10 for the guide member 12 for motion guidance
In order to make the sliding of the sliding guide easier, a slight gap SG is created between both side surfaces of the sliding guide member 12 positioned in the width direction.

At the downwardly extending end portions of the pair of first sandwiching arms 10c and 10d and the one pair of second sandwiching arms 10e, slide guides are formed below the lower surface of the slide guide member 12. Engagement positioning portions 10f that are bent toward the lower surface of the guide member 12 and face the lower surface are formed, and each of the engagement positioning portions 10f is particularly well shown in FIG. In order to facilitate the sliding of the slide operating member 10 with respect to the sliding guide member 12 in the extending direction of the sliding guide member 12, a slight gap is formed between the sliding guide member 12 and the lower surface of the sliding guide member 12. We are creating LG.

On the lower surface of the main plate 10a, outside the one side surface located in the width direction of the slide guide member 12, there is a further intermediate position 1 between the pair of first holding arms 10c and 10d. A slide switch operating portion 10g extending below the pair of first holding arms 10c and 10d is formed. A slight gap SG is also created between the slide switch operating portion 10g and the one side surface located in the width direction of the slide guide member 12. The extended end portion of the slide switch operating portion 10g is also bent to face the lower surface of the sliding guide member 12 below the lower surface of the sliding guide member 12 and faces the lower surface. A pair of first holding arms 10c and 10d and a pair of second holding arms 10e are provided between the lower surface of the guide member 12 and the bent portion of the extended end of the slide switch operating portion 10g. A gap much larger than the slight gap LG between the engagement positioning portion 10f at the downwardly extending end portion and the lower surface of the slide guide member 12 is formed.
An engaging recess 10h with which a slide knob of a slide switch (not shown) of an electric device (not shown) using the slide operating device of FIG. 1 is engaged with the bent portion of the extended end portion of the slide switch operating portion 10g. Are formed.

In the slide operating member 10 of the conventional slide operating device constructed as described above, a pair of first
The holding arms 10c and 10d and one second holding arm 10e are perpendicular to the sliding direction of the slide operating member 10 with respect to the slide guide member 12 in the first direction (sliding in the conventional example of FIG. 1). It functions as a sandwiching portion that sandwiches the sliding guide member 12 from the widthwise direction of the guide member 12).
Further, the engagement positioning portion 1 at the downward extending end of each of the pair of first holding arms 10c and 10d and the one second holding arm 10e.
0f is in contact with the lower surface of the sliding guide member 12 so that the second direction is perpendicular to the sliding direction and the first direction (the vertical direction of the sliding guide member 12 in the conventional example of FIG. 1). Functions as a positioning unit for positioning.

[0009]

In the conventional slide operating device constructed as described above in detail, when vibration is generated in the electric equipment, a slight gap is formed on both sides of the sliding guide member 12 in the width direction. Due to the slight clearance LG on the lower surface side of the SG and the sliding guide member 12,
The slide operating member 10 may vibrate in the width direction (that is, the first direction) and the vertical direction (that is, the second direction) of the slide guide member 12.

When the electric device is a tape recorder and is equipped with a speaker, the sound reproduced from the speaker may vibrate the outer casing of the electric device, which in turn may cause the slide operating member 10 to vibrate. Even if the sound generated by the vibration of the slide operation member 10 is extremely small, it mixes with the sound reproduced from the speaker and deteriorates the sound quality of this reproduced sound.

The present invention has been made under the above circumstances, and an object of the present invention is to generate vibration between a slide guide member and a slide operating member even when vibration is applied from the outside. There is no slide operating device.

[0012]

In order to achieve the above-mentioned object of the present invention, a slide operating device according to the present invention comprises: a guide member for sliding guide; a first direction perpendicular to the sliding direction. It has a sandwiching part for sandwiching the slide guide guide member, and a positioning part for contacting the slide guide guide member to perform positioning in a second direction perpendicular to the sliding direction and the first direction. A slide operating member; and a portion of the sandwiching portion of the slide operating member that comes into contact with the slide guiding guide member contacts the positioning portion of the slide operating member with the slide guiding guide member by the sandwiching force of the sandwiching portion. It is characterized in that it has a predetermined shape that generates a moving force in the contact direction.

[0013]

In the slide operating device according to the present invention which is configured as described above, the positioning portion of the slide operating member is moved by the holding force applied to the slide guide member by the holding portion of the slide operating member. A moving force in the direction of abutting the sliding guide member is generated, and a gap between the sliding guide member and the holding portion of the slide operating member and a position between the sliding guide member and the positioning portion are generated. The gap is eliminated.
