Description

[Detailed Description of the Invention] The present invention relates to a card with a built-in electronic sounding device that can be easily opened and closed and that ensures the functionality of the electronic sounding device.

An electronic sounding device that is built into a card and plays a melody when the card is opened has been proposed.
Conventional cards are not designed to incorporate electronic sounding elements, so if the electronic sounding element is simply attached to the card, or a piece of inner paper is pasted to the inside to hide the electronic sounding element, the card can be opened and closed smoothly. figure,
In addition, the electronic sounding body is easily subjected to external force, and incorporating the electronic sounding body makes the card easy to bend or break, and the operation of the electronic sounding body switch becomes uncertain, making it impossible to ensure its function. It has drawbacks such as bulging and unsightly design.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, an object of the present invention is to propose a card with a built-in electronic sounding device that has a sufficient function of the electronic sounding device, allows smooth opening and closing of the card, and is also preferable in terms of design.

The feature of this invention is that the electronic sounding body and the cardboard of approximately the same thickness as the electronic sounding body are attached to the double-layered half side of the card, which has two layers on the outside and inside and is folded in half in the middle. The card piece that becomes the inner side when it is held and folded in half is provided with play between two folds at an interval of approximately the same size as the thickness of the cardboard.

The present invention will be explained below with reference to illustrated embodiments. 1st
As shown in FIGS. 4 to 4, the card with a built-in electronic sounding element is formed by folding the outer card piece 1 and the inner card piece 2 into two layers in the middle, and the two-layered part 1a on the half side of the card, A cardboard 3 is clamped and fixed to the cardboard 3, and an electronic sounding body 4 is inserted and held in the recess 3a of the cardboard 3.

The outer and inner card pieces 1 and 2 are made of paper or a thin plate made of synthetic resin, and the card piece 2 has two folds 2 in the middle with an interval l that is approximately the same size as the thickness of the cardboard 3.
b, 2c are formed, and the two-layered portion 2a and the cardboard 3 are bonded, for example, between the ends 2d and 3b with adhesive, and the card piece 1 on the other half side where the cardboard 3 is not clamped and fixed.
and 2 are glued with adhesive at the adhesive position 1c on the other half side than the fold line 1b of the card piece 1 and the adhesive position 2c on the other half side from the fold line 2c of the card piece 2. As shown in FIG. 5, the card is closed and fixed so that the portion 2f of the space 1 is in contact with the end 3c of the cardboard 3.

The thickness of the cardboard 3 is approximately the same as the thickness of the electronic sounding body 4.

As shown in FIG. 2, the switch contact piece 4a of the electronic sounding body 4 protrudes from the top surface of the cardboard 3 close to the fold 2b of the card piece 2 or from the end 3c of the cardboard 3 facing the portion 2f of the fold interval 1. When a normally closed switch is used as the switch, the switch is turned on when the switch contact piece 4a protrudes.

When the electronic sounding element built-in card is configured as described above and the card is closed, one fold line 2b is bent at the corner of the cardboard 3, as shown in FIG.
The other fold 2c is sandwiched between the end 3c of the cardboard 3 and the other half of the card piece 2 so that the other fold 2c is on the lower side, so the card is neatly folded in half and does not bulge. This is preferable from the design point of view, and the electronic sounding body 4 built into the card is protected by the cardboard 3, and the vicinity of the fold 2b of the card piece 2 and the portion 2f at the interval 1 are in close contact with the cardboard 3, so that the switch does not come into contact with the card. The piece 4a is reliably pushed into the cardboard 3 and turned off.

Next, when the card is opened, the folds 2b and 2c are stretched and stretched on both sides as shown in Fig. 2, and are separated from the contact surface with the cardboard 3, creating play and allowing the card to be opened smoothly. The switch contact piece 4a is also protruded from the end face of the cardboard 3 and is surely operated to turn on, and this on operation energizes the circuit of the electronic sounding body and plays a melody.

In the above explanation, the inner card piece 2 has two folds 2b and 2c, and the outer card piece 1 has two folds 2b and 2c.
Although the card is shown folded in half at point b, a crease may be made at the position of arrow A in FIG. 5 on the outer card piece to make opening and closing smoother.

Since the present invention is constructed as described above, two pieces of paper are placed on the inner card piece at intervals of approximately the same size as the thickness of the cardboard.
With a simple structure that creates play at the folds of the book, when the card is folded in half, it folds neatly without bulging, creating a design-friendly condition. By holding the card between the outer card pieces, the card will not be folded unnecessarily in the middle and will not be subjected to direct external force, and when the card is opened, the fold will be separated from the cardboard and the card will be opened smoothly. The switch contact piece of the electronic sounding element has a built-in electronic sounding body card that has excellent practical effects such as the fold of the switch contact piece being in close contact with the cardboard or being separated from it, ensuring stable operation and no contact failure. can be provided.
