Abstract

The utility model relates to a portable writing box with light inside, which comprises a box body, a power supply circuit, light emitting diodes, a lamp cap, writing paper, a paper supporter, etc. The writing box can emit scattered light from the back of the writing paper through the light-passing board with the self-provided electric light source in the box, thereby, the writing is free from the limit of objective conditions, the writing and drawing can be done as usual even if the environment is dark. The utility model has the advantages that convenience can be brought for the working of writing and drawing under the dark condition; the light inside does not make a difference to the surrounding environment and only for writing and drawing; the writing box is also provided with a device for direct illumination in the box.

Description

Portable writing box with light inside

The utility model relates to a kind of writing cartridge that is easy to carry and self is furnished with light source, is writing implement.

Traditional notebook binds into book form or various forms such as loose-leaf, but all must could write thereon under the condition that natural daylight or other extraneous fill-in lights are arranged.Under night or dark condition, can't use, this give need in night or dark, write or exactly the work of generating writing pattern bring very big puzzlement.In order to overcome this conventional book writing tools defective under these conditions, the special the utility model that proposes.

The utility model is a kind of portable interior light writing cartridge.Mainly form by box body, power circuit, light emitting diode, lamp holder, writing paper etc.This writing cartridge is by the electric light source that carries in the box and make the light scattering see through the back side emission scattered light of light-passing board from writing paper, write the restriction that is not subjected to objective condition thereby make, even also can write as usual or describe at the dark place, give any need be under dark condition write, the work of describing brought convenience.Also be provided with the device that is used for direct illumination in the writing cartridge simultaneously.

Describe in detail below in conjunction with accompanying drawing: as Fig. 1, big or small two Room are arranged in the box body 1, the light emitting diode 3 more than 4 is housed on the big indoor base plate, box body 1 front sidewall is provided with magnetic stripe 2, printing opacity mouth 4, right side wall is provided with switch 5, on the partition of big chamber and cell printing opacity mouth 13 is arranged.The rear wall upper edge of box body 1 connects lid 6.Light-passing board 11 is housed on the lid 6, and the loose-leaf frame 9 that sheet metal 10, a side is housed on the flanging in its forward position and has a strap 7 is hinged, and is with helical ring 12 on the crossbearer of loose-leaf frame 9 and clamps loose leaf paper 8.As Fig. 2, small electric bulb 18 is housed in the reflective optical system 19, constitute lamp holder.Small electric bulb 18 adopts flexible circuit conductor to be connected with circuit.The bottom of reflective optical system 19 has a pin 14 to insert in 15, and socket 15 is connected as a single entity with copper clad plate 20, and reflective optical system 19 can be swung 0-180 ° by pin 14 in socket 15.Battery 17 is placed between battery lead plate 21 and the electrode spring 22, electric routing switch 5 controls, and device shown in Figure 2 is put in the cell of box body 1.As Fig. 3, it is the direct illumination circuit that the contact A of power supply E and switch 5, small electric bulb 18 are linked to be the loop; It is interior optical circuit that the contact B of power supply E and switch 5, light emitting diode 3 and resistance R are linked to be the loop, and 0 is opened circuit for neutral gear.Light emitting diode 3 is single electric current 5mA, and small electric bulb 18 is 2.2V, 250mA.

Embodiment: when carrying the utility model (is example with Fig. 1), loose-leaf frame 9 and paper 8 are upwards rolled over the inner surface that is put in lid 6, and the lid 6 that closes then is adsorbed on the magnetic stripe 2 sheet metal 10.When using, open the lid 6, upset loose-leaf frame 9 and paper 8 make to box, lid 6 then closes, overturn again loose-leaf frame 9 and paper 8 makes on its outer surface that is put in lid 6, and paper 8 covers on the light-passing board 11 just, and light-passing board 11 is the direct frosted glass of transmitted light not, or be coated with coating, or one side has glass plate or the plastic plate of protruding flower.Write or only stay a piece of paper on lid 6 when describing, remaining paper is opened.The Shi Keyi that works on last time changed page.When working under dark condition, switch 5 can be opened and be allocated to B, this moment, the light emitting diode 3 in the box was bright, and saw through light-passing board 11 scattered light is thrown at the paper back of the body, for writing and the work of the describing condition that facilitates.Also lamp holder (small electric bulb 18 and reflective optical system 19) rotary alignment printing opacity mouth 13 can be allocated to contact A with switch 5, the light that uses small electric bulb 18 to send.When continuing to write work, lamp holder not being turned to printing opacity mouth 4, make it be directly used in illumination.

The utility model volume is little, structure is ingenious, the use that is easy to carry, and when especially using in dark, light only for writing or describe work, does not exert an influence to surrounding environment in it.
