A drawer portion that is housed in the housing and has a terminal portion that closes the opening, and that is supported on both side surfaces of both ends of the printed circuit board on which a printed circuit board mounted with a message memory that can be exchanged according to a message to be notified is in sliding contact with the inner surface of the case. And, in the notification device including a connection lead wire connected between the notification unit and the printed circuit board, the message memory is mounted on a printed circuit board on the terminal unit side of the drawer unit,
A stopper is provided on the sliding contact surface between the case and the drawer to prevent the drawer from being pulled out at a position where the message memory is exposed from the case. The stopper is provided, for example, on a side surface of the drawer portion in a direction of insertion of the drawer portion in a direction of a semi-arrowhead, and is provided on an inner surface of the case to contact the protrusion to prevent the drawer portion from coming off the case. And a groove having a contact portion.

[0007]

The notification device of the present invention is, for example, a semi-arrow-shaped protrusion provided on the side surface of the drawer portion in the insertion direction of the drawer portion, and a case provided on the inner surface of the case and abutting on the protrusion to contact the case of the drawer portion. A stopper having a contact portion for preventing the drawer from being pulled out from the case, and a stopper for preventing the drawer from being pulled out from the case by a predetermined distance or more. Of the electronic circuits, only the message memory is exposed from the case, so that when the message memory is replaced, the other circuit is not carelessly touched, and damage to the electronic circuit due to static electricity is prevented. Further, since the drawer portion is not drawn out beyond the predetermined distance, the connection lead wire of the speaker is prevented from being strongly pulled and disconnected.

[0008]

FIG. 1 shows an embodiment of a voice notification device according to the present invention. FIG. 1 (a) is an exploded perspective view, and FIG. 1 (b) is a sectional view taken along line AA of FIG. 1 (a). The voice notification device of the present invention shown in FIG. 1 is different from the conventional voice notification device shown in FIG. 4 in that a semi-arrowhead projection 14 provided on both sides of the drawer portion 3 in the insertion direction of the drawer portion 3 is provided. A stopper 16 comprising a groove 15 having a contact portion 15a for contacting the projection 14 to prevent the drawer 3 from coming off the case 1 is provided on the inner surface of the projection 1. When the drawer portion 3 is inserted into the case 1, the semi-arrow-shaped protrusion 14 crosses over the inner surface of the case on the front side of the groove 15 due to the elasticity of both side surfaces of the drawer portion 3.
When the drawer 3 is further pushed in, the protrusion 14 moves in the groove 15 in the depth direction. Then, when the insertion is completed, it is fixed with the mounting screw 13 similarly to the conventional device.

When exchanging the message memory 9 with this voice notification device, the drawer 3 is pulled out as shown in FIG. 3, but at this time, as shown in FIG.
As shown in FIG. 2 (a), 5a and the end face on the near side of the half arrowhead-shaped projection 14 come into contact with each other, so that the drawer 3 is drawn out only by a certain distance L. The message memory 9 to be replaced among the internal circuits of the drawer 3 is arranged in advance so that only the message memory 9 to be exposed is exposed from the case 1. An accident in which the electronic circuit 10 is damaged by touching static electricity is prevented. In addition, since the drawing distance of the drawing part 3 is limited to a certain distance L, the connection lead wires 11 connected to the speaker 2 are connected.
Also, the pulling force of the drawer 3 when sliding from the case 1 does not work, and the accident that the connecting lead wire 11 of the speaker 2 is strongly pulled and disconnected can be prevented.

In order to completely pull out the drawer 3 from the case 1, both side surfaces of the drawer 3 provided with the protrusion 14 are pressed inward, and the elasticity of the protrusion 14 makes the shape of a half arrowhead.
Is moved inward to disengage with the groove 15 and to be pulled out to the front. In this embodiment, case 1
Cover the electronic circuit other than the message memory mounted on the printed circuit board, for example, the control circuit 7. However, it is not always necessary to cover the electronic circuit with the case 1. Let me support
The control circuit 7 may be covered by the plate.

Although the projections 14 are provided on both side surfaces of the drawer 3 and the grooves 15 are provided on the inner surface of the case 1, the protrusions may be provided on the inner surface of the case 1 and the grooves may be provided on the side surfaces of the drawer 3. Good. Further, in the above-described embodiment, the voice notification device that transmits a message by voice has been described. However, the present invention can be similarly applied to a character display device using a display panel instead of a speaker.

[0012]

According to the notification device of the present invention, when the message memory is replaced, only the message memory circuit is exposed from the case, so that the message circuit is not inadvertently touched by other circuits, thereby preventing damage to the electronic circuit due to static electricity. In addition, since the connection lead wire of the notification unit is not strongly pulled and the disconnection is prevented, the handling becomes easy.
