DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A preferred embodiment of the present invention will hereinafter be described in detail with reference to the accompanying drawings. As shown in FIG. 1 , a bag 100 according to the embodiment of the present invention includes an electric power supply device 101 .
The electric power supply device 101 can be an arbitrary device that can generate electric power. For example, the electric power supply device 101 can be a battery or a solar cell. If the electric power supply device 101 is the battery, a conventional battery can be used. It is preferable that the battery is disposed inside of the bag 100.
If the electric power supply device 101 is the solar cell, a conventional solar cell can be used. It is preferable that the solar cell is disposed outside of the bag 100 so as to generate electric power using solar heat.
The bag 100 includes two covering surfaces 103 and 105 that are separably face each other, so that an opening portion can be formed when the two covering surfaces 103 and 105 are separated from each other. When a zipper 107 is closed, the two covering surfaces 103 and 105 are coupled to each other so that the bag 100 is closed. On the other hand, when the zipper 107 is open, the two covering surfaces 103 and 105 are separated from each other so that the bag 100 is open.
Although in this embodiment the two covering surfaces 103 and 105 are attached to each other through the zipper 107, the two covering surfaces 103 and 105 can also be coupled through other coupling means.
A magnet 109 and a switch 111 are installed respectively to the two covering surfaces 103 and 105.
The magnet 109 and the switch 11 1 are disposed respectively at the two covering surface 103 and 105 such that the switch 111 is turned on or turned off according to attachment or separation of the two covering surfaces 103 and 105. In addition, the bag 100 according to the embodiment of the present invention includes a light emitting device 113 that can be supplied with electric power from the electric power supply unit 101 , and that generates light using the supplied electric power.
The light emitting device 113 can be an arbitrary device that can emit light using electric power. As an example, the light emitting device 113 can be a bulb or an LED (light emitting diode). In FIGs. 1 to 3, the light emitting device 113 is the LED.
The light emitting device 113, as shown in FIG. 1 , is preferably disposed inside of the bag 100 such that an interior space of the bag 100 can be illuminated by light emitted by the light emitting device 1 13.
If the two covering surfaces 103 and 1 05 are separated from each other, i.e. if the bag 100 is open, the electric power is supplied to the light emitting device 1 13 from the electric power supply device 101 so that the
light emitting device 1 13 emits light. On the other hand, if the two covering surfaces 103 and 105 are attached to each other, i.e. if the bag 100 is closed, the electric power is not supplied to the light emitting device 1 13.
FIG. 2 shows a circuit in which the switch 1 1 1 is turned off if a distance between the magnet 109 and the switch 1 1 1 is less than a predetermined distance, i.e. if a magnetic force of the magnet 109 acting on the switch 111 is relatively little, and the switch 1 1 1 is turned on if a distance between the magnet 109 and the switch 1 1 1 is equal to or greater than the predetermined distance, i.e. if a magnetic force of the magnet 109 acting on the switch 1 1 1 is relatively great. FIG. 3 shows a circuit that operates in an opposite fashion.
The predetermined distance can be set as a distance between the two covering surfaces 103 and 105 in which the bag 100 can be considered as being open. By regulating a magnetic force of the magnet 109, the predetermined distance can be regulated.
As shown in FIG. 2, if the two covering surfaces 103 and 105 are attached to each other so that the bag 100 is closed, the distance between the magnet 109 and the switch 1 1 1 becomes less than the predetermined distance so that the switch 1 1 1 is turned off and the electric power is thereby not supplied to the light emitting device 1 13.
On the other hand, if the two covering surfaces 103 and 105 are separated from each other so that the bag 100 is open, the distance between the magnet 109 and the switch 11 1 becomes equal to or greater
than the predetermined distance so that the switch 1 1 1 is turned on and the electric power is thereby supplied to the light emitting device 1 13. Consequently, when the bag 100 is open, the light emitting device 1 13 emits light, thereby illuminating the interior portion of the bag 100. Referring to FIG. 3, a circuit including a separate inverting circuit is shown, in which the switch 1 1 1 is turned on if the distance between the magnet 109 and the switch 1 1 1 is less than a predetermined distance.
A resistor R1 127 and the switch 1 1 1 are connected to the electric power supply device 101 , and the light emitting device 1 13 and a resistor R2 129 are also connected to the electric power supply device 101 . At this time, the resistor R1 127 and the light emitting device 1 13 are connected in parallel.
The circuit is provided with a Darlington transistor 121 that is a semi conductor element and includes two transistors Q1 123 and Q2 125 that are connected to each other. A base terminal of the transistor Q1 123 is connected to a point © between the resistor R1 127 and the switch 1 1 1 . Collector terminals of the transistors Q1 and Q2 123 and 125 are respectively connected to the resistor R2 129. An emitter terminal of the transistor Q1 123 is connected to a base terminal of the transistor Q2 125. If the two covering surfaces 103 and 105 are separated from each other, i.e. if the bag 100 is open, as shown in FIG. 3, the distance between the magnet 109 and the switch 1 1 1 becomes equal to or greater than a predetermined distance and the switch 1 1 1 is thereby turned off.
If the switch 1 1 1 is turned off, a positive electric potential passing the resistor R1 127 is applied to the base of the transistor Q1 123, so that the transistor Q1 123 is turned on. Consequently, a current flows from the collector terminal of the transistor Q1 123 to an emitter terminal of the transistor Q2 125, and the transistor Q2 125 is thereby turned on.
Accordingly, a current flows through the light emitting device 1 13, so that the light emitting device 1 13 emits light.
On the other hand, if the two covering surfaces 103 and 105 are attached to each other, i.e. if the bag 100 is closed, the distance between the magnet 109 and the switch 1 1 1 becomes less than the predetermined distance and the switch 11 1 is thereby turned on.
If the switch 1 1 1 is turned on, electric potential at the point © becomes zero. Consequently, the transistor Q1 123 is turned off and the transistor Q2 125 is also turned off. Accordingly, a current flow is applied to the light emitting device 1 13, and thereby the light emitting device 1 13 does not emit light.
As explained in the above, if the bag 100 is open, the electric power is supplied to the light emitting device 1 13 from the electric power supply device 101 and the light emitting device 1 13 thereby emits light, and if the bag 100 is closed, the electric power is not supplied to the light emitting device 1 13.
While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is
to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
