Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of a telephone which is an example of the communication device of the present invention.

In FIG. 1, a telephone is a handset unit 1.
And the telephone body 2. The telephone body 2 further includes a dial key unit 3 and a function key unit 4 used for one-touch dialing or the like.

A plurality of function keys 5 are arranged in the function key section 4, and a display window 6 as a through hole for displaying the function name of each function key 5 is provided near each function key 5. Are opened corresponding to the function keys 5, and a space below each display window 6 is a space. Each display window 6 on the side wall of the telephone body 2
Are formed integrally with the display window 6 at three levels, and two sheet insertion openings 7 opened in the side wall are formed in the space portion. The sheet 8 as a sheet display member having the following can be inserted.

As shown in FIG. 2, when the sheet 8 is inserted from the sheet insertion opening 7 into the space, the display 8 is provided with three display windows 6 integrated with each other. On the display section 8a located below the window 6, a function name and the like are described. Also, at one end of the sheet 8 opposite to the display section 8a, a gripping margin 8b for gripping when the sheet 8 is inserted into or pulled out of the space is formed. A small hole 8c with which a retaining projection to be described later is engaged is formed.

Next, the function key section 4 will be described in detail.

As shown in FIG. 2, each display window 6 is provided on the lower surface of an upper case 9 as a housing of the function key section 4 (see FIG. 1).
Transparent member 10 having a convex portion 10a formed corresponding to
However, each projection 10a is fitted into each display window 6 and is in close contact therewith. Further, below the transparent member 10, a sheet guide 11 as a guide member is joined to the upper case 9 by welding or the like, and the sheet guide 11 also serves to support the transparent member 10.

A predetermined surface on the upper surface of the sheet guide 11 has an upright surface 11a serving as a guide when the sheet 8 is inserted.
Are formed along the insertion direction of the sheet 8, and the transparent member 1
A space having a height corresponding to the height of the upright surface 11a is formed between the sheet guide 11 and the sheet guide 11. A concave portion 9b is formed in the side wall of the upper case 9, and an opening formed by the concave portion 9b and the upper surface of the sheet guide 11 serves as a sheet insertion port 7 (see FIG. 1).

The function key 5 is used for the sheet guide 11
Then, from below the sheet guide 11, the sheet guide 11,
It is attached through holes formed in the transparent member 10 and the upper case 9.

As described above, by adopting a structure in which the sheet 8 can be inserted from the side of the housing, the attachment and detachment of the sheet 8 can be easily performed only by sliding the sheet 8 to the side.

A plurality of protrusions 11b are provided at intervals on the upper surface of the sheet guide 11 where the display 8a of the sheet 8 is located. The height of each projection 11b is
The height is lower than the height of the space formed by the transparent member 10 and the sheet guide 11, and the height is such that the sheet 8 can be inserted between the transparent member 10 and the tip of the projection 11b. For this reason,
When the sheet 8 is inserted into the space, the display portion 8a of the sheet 8 is placed on the tip of each protrusion 11b and is close to the transparent member 10, so that the visibility of the display portion 8a is improved and As compared with the case where the height of the space portion is uniformly made equal to the gap between the transparent member 10 and the tip of the protrusion 11b, each protrusion 11b contacts the sheet 8 by point contact, so that the frictional resistance of the sheet 8 is increased. And the insertion and withdrawal of the sheet 8 becomes easier. Here, each protrusion 11
It is desirable that the shape of the leading end of b be hemispherical so that when the leading end of the sheet 8 comes into contact with the protrusion 11b, the sheet 8 can easily escape above the protrusion 11b.

As shown in FIG. 3, when the operator actually looks at the display window 6, the viewpoint F of the operator is usually not directly above the display window 6 but in front (in the direction of the arrow in the drawing). is there.
For this reason, if the position of the display section 8a of the sheet 8 is directly below the display window 6, especially when the thickness of the upper case 9 is large, the display section 8a may be hidden behind the upper case 9 and become invisible. Therefore, the positional relationship between the display section 8a of the sheet 8 and the display window 6 is such that the display section 8a is inserted at a position shifted by a distance C in a direction opposite to the near side from a position directly below the display window 6. Is done. This distance C depends on the thickness of the upper case 9,
The optimum value is set according to the inclination angle of the function key unit 4 (see FIG. 1).

Next, the configuration near the sheet insertion slot will be described in detail.

As shown in FIG. 4, a retaining projection 9a extending downward is provided near the sheet insertion port 7 on the lower surface of the upper case 9.
When the sheet 8 is completely inserted into the sheet insertion port 7, the retaining projection 9a is fitted into the small hole 8c formed in the sheet 8, and the sheet 8 is inserted into the sheet insertion port 7.
It is intended to prevent inadvertent escape from the device. The height of the retaining projection 9a does not hinder the insertion of the sheet 8,
In addition, it is desirable that the height is such that it can be securely fitted into the small hole 8c.

The end of the sheet guide 11 on the side of the sheet insertion opening 7 is provided for holding the sheet 8 in order to facilitate the insertion of the sheet 8 and to protect the margin 8b of the sheet 8 from impact. Except for a portion corresponding to the margin 8b, an insertion guide 11c extending laterally is protruded.
The protruding amount E of the insertion guide 11c is
The protrusion amount D is larger than the protrusion amount D of the b, and the upper surface of the insertion guide 11c and the upper surface of the sheet guide 11 are on a plane.

When inserting the sheet 8 into the function key unit 4 configured as described above, the position of the sheet insertion port 7 and the display unit 8a of the sheet 8 are aligned, and the display unit 8a is placed on the insertion guide 11c. Insert it in the state. As the sheet 8 is inserted, the sheet 8a is lifted toward the transparent member 10 by the protrusions 11b and inserted. When the sheet 8 is completely inserted, the small hole 8c Automatically fits into the retaining projection 9a, and the seat 8
Is stopped.

On the other hand, when the sheet 8 is pulled out, the retaining projection 9a is pushed down by pushing the sheet 8 downward.
