Description

[Detailed description of the invention]

[0001]

[Field to which the invention belongs]

 The present invention relates to a pen with an illumination function that includes a light emitter and can irradiate light projected from the light emitter to the outside through the entire pen including a cap.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a pen having a lighting function including a lighting unit and a writing unit is known. However, in the past, various pens with an illumination function that can obtain the required illuminance during writing have been proposed, but the cap attached to the tip of the pen is formed in a transparent and various character shape. However, there is no proposal for a pen with a lighting function that can be used as a playground equipment such as a penlight by emitting light from the light-emitting body with the cap attached.

[0003]

[Problems to be solved by the invention]

 This invention aims to provide a pen with an illumination function that not only functions as a writing implement but also as a playground equipment.

[0004]

[Means for Solving the Problems]

 Means adopted by the present invention to solve the above-described problem is that in a pen with a lighting function provided with a luminous body, a cap attached to the tip of the pen is formed of a member having a light transmitting property and is projected from the luminous body. It is characterized in that light is emitted to the outside via the cap.

Further, the cap is characterized by being formed of a transparent or translucent member.

Further, the cap is formed in a shape of various characters.

[0007] Further, the writing rod and the tip are formed of a transparent member.

Further, in a pen with a lighting function provided with a luminous body, a cap attached to the tip of the pen is formed into a shape of various characters using a transparent member, and light projected from the luminous body is used for the character. It is characterized in that the light is radiated to the outside via a cap formed in a shape.

[0009]

[Embodiment of the invention]

 A preferred embodiment of the present invention will be described in detail below. Referring to FIGS. 1 and 2, the pen with lighting function according to the present invention includes a writing unit (1), a lighting unit (2), and a cap (3). The writing section (1) comprises a core (11) and a hollow cylindrical writing rod (12) capable of receiving the core (11) inside. The light rod (12) and a tip (13) described later emit light projected into the light rod (12) when light is projected from a light-emitting body (26) of the lighting unit (2) described later. It is made of a transparent or translucent plastic so that it can be irradiated to the outside, but it goes without saying that other members may be used as long as they are transparent or translucent.

[0010] One end of the writing rod (12) is formed such that its diameter gradually decreases and the core (11) is exposed from the tip. In the present embodiment, the tip (13) is screwed in to facilitate replacement of the core (11) and is detachable. However, the tip (13) is not detachable but is integrated. Needless to say, it may be molded into a solid. A reinforcing ring mounting screw (14) is formed at the other end of the writing rod (12), so that the reinforcing ring (15) can be screwed. In this embodiment, a metal reinforcing ring (15) is interposed at the other end of the writing rod (12) to reinforce the connection with the lighting unit (2). The writing rod (12) and the lighting section (2) may be directly connected without interposing a ring. A luminous chamber (16) is formed inside the other end side of the pen, and when the illuminating part (2) is connected to the pen (12), it protrudes from a luminous case (21) described later. Luminous body (26) is acceptable. Although a core holder (17) is formed in the upper part of the luminous body chamber (16), the end of the core (11) is brought into contact with the luminous body chamber (16) without providing the core holder. Needless to say, it is also possible to achieve the center press.

The illuminating section (2) comprises a luminous body case (21) and a switch section (22), both of which are formed of plastic. A switch mounting screw (23) is formed at the lower end of the luminous body case so that both can be screwed together. A battery (24) and an insulating ring (25) are provided in the luminous body case (21), and a luminous body (26) is provided above the insulating ring (25). A plurality of LED lamps (27) are provided inside the luminous body to enable light emission in a plurality of colors. In the present embodiment, two blue and orange LED lamps are used. However, the number of LED lamps and the color of emitted light are not limited to these. One connecting leg of the LED lamp (27) is protruded from a hole formed in the insulating ring (25), and always keeps contact with one pole of the battery (24). The other connecting leg contacts one end of a metal path (28) provided on the inner wall of the light-emitting body case (21) and in contact with a rotary switch (30) described later at the other end, and emits light of the LED lamp (27). -Enables extinction control.

The switch section (22) includes a light-emitting body case (29) and a switch knob (30), and the switch knob (30) is rotatably connected to the light-emitting body case (29). The luminous body case (29) and the switch knob (30) are both formed of plastic, but are not limited to this as long as they are insulating. A metal rotary switch (31) is adhered to the upper end of the switch knob (30), and when the user rotates the switch knob (30), the rotary switch (31) also rotates. ing. Referring to FIG. 1, the rotary switch (31) has a convex center, and always keeps contact with one pole of the battery (24). The rotary switch (31) is provided with three contact legs (32) extending radially from the center, and one of the contact legs (32) is rotated by rotation of the rotary switch (31). When the book contacts the end (33) of the metal path (28), one of the LED lamps (27) is energized and the LED lamp emits light. When all of the contact legs (32) are not in contact with the end (33), the light is extinguished. In this embodiment, three connecting legs (32) are provided, but the number is not particularly limited.

The cap (3) is formed of a transparent or translucent plastic in the shape of various characters as shown in FIG. 1, so that the light projected from the luminous body (26) is used to cover the character-shaped cap. Can be radiated to the outside through The cap (3) has a writing rod chamber (34) formed therein so as to receive the tip of the writing rod (12). Also, the material used for the cap (3) is not limited to plastic as long as it can be radiated to the outside through the cap formed in the shape of various characters, so long as it is transparent or semi-transparent. Of course.

[Effect of the invention]

 According to this invention, by forming the cap into the shape of various characters using a transparent or translucent member, it is possible to irradiate light projected from the luminous body to the outside through the character-shaped cap. Since it is possible, it can be used not only as a writing instrument but also as a plaything such as a penlight.
