Description

[Detailed explanation of the invention] (Technical field of the invention) This invention is designed so that when a card such as a Christmas card, Valentine's card, birthday card, etc. is opened, lights flash sequentially from a predetermined position and a fragrance is emitted. This is about a card that emits light and scent.

(Technical background of the invention and its problems) Various devices have been devised to generate light from greeting or commemorative cards such as Christmas cards, Valentine's cards, birthday cards, wedding commemorative cards, gift cards, etc. Devices that generate light can be made smaller and thinner by using semiconductor elements such as micro batteries and ICs, but to make these cards even more fun, it is possible to create a scent that matches the picture. There was nothing.

(Purpose of the invention) This invention was made under these circumstances. When the card is closed, it is the same as a normal card, and when the card is opened, it is possible to accurately and accurately create a circuit that generates light suitable for the card. It is another object of the present invention to provide a multi-functional card which allows the user to enjoy the visual effects of light and generates a scent by using a light switch means which can be reliably operated.

(Summary of the invention) This invention relates to a card that emits light and scent, and includes a light generation circuit equipped with a pulse oscillator and a ring counter, a light emitting element connected to the light generation circuit, and a power supply to the light generation circuit. A battery and a light switch means for turning on and off the light generation circuit by detecting light are integrated into a flat plate to form a light generation device, and this light generation device is embedded and attached in a card, and the light generation circuit is turned on and off by detecting light. The optical switch means is turned on and off in response to opening and closing, and one or the entire surface of the card is made of a scented sheet.

(Embodiment of the invention) Fig. 1 shows the schematic structure of a card 1 showing an embodiment of this invention, and the card 1 is used with the cover 2 opened. (In this example, it's a Mother's Day gift card)
is expressed in pictures, letters, etc. on the back side of the front plate 2 and on the back plate 3 which is folded into three. The device 10 is operated to generate light from the light emitting elements 31 and 32 embedded in the eyes and necklace of the mother image 30 drawn on the back plate 3. Here, the material of the card 1 is made of an aromatic sheet 40 that generates the scent of the red carnation 20 depicted on the back plate 3. As shown in FIG. 2, the aromatic sheet 40 is made up of an aromatic film 41 as a base, and papers 42 and 43 layered on both sides of the aromatic film 41. The scent is starting to come out gradually. The aromatic film 41 is made of resins such as polyethylene, polypropylene, vinyl chloride, EVA, nylon, and polyester, and is made by adding fragrance to these resins at a certain rate. There are the inflation method, T-die method, and T-die extrusion method to make a film from this scented resin, and the film 41 made by these methods is used as an intermediate layer, and both sides are coated with high-quality paper that is breathable on both sides. The fragrance sheet 40 is created by laminating the papers 42 and 43. By changing the combination of resins in the aromatic film 41, the intensity and lifespan of the aroma can be controlled, and an aromatic sheet 40 with long-term aroma retention can be realized.

By the way, the light generating device 10 is embedded in the folded cover of the back plate 3 so that it cannot be seen directly by the user, and the light switch means 11 provided in the light generating device 10 controls the opening and closing of the cover 2. It is now detected optically. In order for the light switch means 11 to detect light, a small hole 11A (or a light-transmitting material) is provided in the back plate 3 at a position facing the light switch means 11, so that the cover 2 can be easily detected by the user. When opened, the light incident through this small hole 11A turns on the light switch means 11,
Power is supplied from the battery, and the light generating device 10 operates to generate light.

3A and 3B show the structure of a light generating device 10 that can be applied to this invention. Each element of the light generating device 10 is mounted on a thin rectangular substrate 12, and Disc-shaped micro battery 1
3 is held at its upper part by a pressing plate 16 having an elastic action, and is removably attached to the substrate 12. The IC element 10A including the light generating circuit 36 is mounted on the substrate 12
It is attached to the circuit pattern of Furthermore, light emitting diodes 31 and 32 that generate light are embedded in desired parts of the picture drawn on the back plate 3 (for example, positions to be emphasized such as eyes, neckline, etc.), and are connected to a light generating circuit 36 through lead wires 18. It is connected. The optical switch means 11 has one end connected to the IC element 10A via a lead wire 17, and the other end connected to the micro battery 1.
It is attached so that it touches the side of 3. Here, the circuit configuration of the light generating device 10 is shown in FIG. 4. When the light switch means 11 detects light, the circuit system is turned on, and power is supplied from the battery 13 to the IC element 10A. Supplied IC
Power is also supplied to the light generation circuit 36 within the element 10A. Note that the optical switch means 11 is pnpn.
A photoelectric conversion element such as an optical switch, a photodiode, CdS, or CdSe can be used, and the light generation circuit 36 includes a pulse oscillator 34 that oscillates at a predetermined frequency (for example, 5 Hz), and counts and frequency-divides the output pulses of the pulse oscillator 34. and an amplifier 33 that amplifies the power of the output of the ring counter 35 and causes light emitting elements 31 and 32 such as light emitting diodes to emit light.

In such a configuration, since the card 1 is usually traded and sold with the front plate 2 and back plate 3 closed, the light switch means 11 of the light generating device 10 cannot detect light and is turned off. . Therefore, as shown in FIG. 4, the light switch means 11 is off, and the power from the micro battery 13 is not supplied to the light generating circuit 36, and the light emitting elements 31,
No light is emitted from 32 either. And card 1
When the card 1 is sold and the user is ready to use the card 1, the user opens the cover 2, and the light switch means 11 of the light generator 10 detects the light, causing the circuit system to become conductive. do. That is, since the light switch means 11 is turned on in the circuit configuration shown in FIG. are given to each, and light is generated. As a result, the user of the card 1 can see the movement of light from the light emitting elements 31 and 32 embedded in the picture at the same time as opening the cover 2, and can enjoy an even more three-dimensional effect from the card 1. becomes. And card 1
When a predetermined period of time has elapsed since the opening of the light emitting device 10, the light generating device 10 stops outputting an optical signal, so that light from the light emitting elements 31 and 32 is no longer output. Furthermore,
When the cover 2 of the card 1 is closed, light from the outside is blocked, and the light generating operation of the light generating device 10 is stopped by turning off the light switch means 11.

As described above, according to the card of this invention, by generating light every time the card is opened, it is possible to enjoy the three-dimensional effect seen from the eyes. In addition to this, the fragrance sheet that constitutes part or all of the card allows the user to smell a fragrance corresponding to the card when the card is opened.

Incidentally, the aromatic sheet can be used as a part of the card, or the whole can be used as an aromatic sheet.
