BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting pen, and more particularly, to a button actuated light emitting pen that enables selective illumination while simultaneously exposing and withdrawing a nib by button operation.

Various kinds of light-emitting pens are known, in which light-emitting members such as lamps and LEDs are installed at the front end and a battery is built in to allow selective illumination by switching operations. In addition, a pen having a push button provided at the rear end of the barrel so as to be able to expose and withdraw the writing lead is widely used, and a light emitting pen having both the above-described lighting function and the writing out / retracting function is also known.

However, the light-emitting pen having a writing retrieval / retreat function is illuminated every time the writing lead is exposed, and thus, there is a problem in that the waste of the battery is large in the case of daytime when lighting is unnecessary. There is a kind of a button for leaving the pen and a switch for lighting separately, but it is somewhat inconvenient because the two operations must be separated.

Accordingly, it is an object of the present invention to provide a button-operated light-emitting pen that enables the selection of the writing lead withdrawal and illumination by interlocking the operation of the writing lead withdrawal button and the switch operation.

According to the present invention, the object is provided in a tubular outer barrel, a writing lead which is accommodated in the barrel and elastically urged in a retracting direction by a spring, and has a writing nib mounted on the tip side thereof, and installed in the tip region of the barrel. A light emitting member and a battery for supplying power to the light emitting member, a rotary slider capable of sliding and rotating the barrel in the longitudinal direction by contacting the writing core with the rear end, and movable in the longitudinal direction of the barrel at the rear end of the barrel. The light emitting pen includes a control button installed between the control button and the rotary slider, and a driving member installed between the operation button and the rotary slider, the driving member rotating at a predetermined angle each time the rotary slider is pressed against the rotary slider. In the contact with the rear end of the writing lead is capable of longitudinal sliding and rotation of the barrel, the radius A rotation slider having at least one pair of actuating ribs projecting in the direction and at least two pairs of mutually opposing stops which are separated by guide ribs while keeping the actuating ribs corresponding to the exposure position and the retracted position of the writing core. A cam-shaped housing in which the jaw and the retracting jaw are alternately disposed, and is provided in one of the conductors facing the light emitting member from the battery, and only when the rotating slider is stopped by the opposite pair of exposure stops. It is achieved by a button-operated light emitting pen, characterized in that it comprises a switching means for electrically connecting the conductive wire.

Here, the switching means may include a first contact disposed in an area of one side of the pair of opposing exposure stops connected to the battery, a second contact disposed in an area of the other exposure stop and connected to the light emitting member, and It can be achieved simply by constructing the rotary slider made of a conductor capable of simultaneous contact with the first and second contacts.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a light emitting pen according to the present invention, Figure 2 is a longitudinal cross-sectional view of the assembled state. As can be seen in these figures, it has an elongated tubular barrel 1 and a writing core 2 accommodated in the barrel 1, the writing core 1 being elastic member in the retracted direction by a spring 4. do. An LED unit 3 is mounted at the tip of the barrel 1, and the LED unit 3 has a through hole so that the nib of the writing lead 2 can pass therethrough. The rotary slider 10 is brought into contact with the rear end side of the writing lead 2, and the rotary slider 10 protrudes in the radial direction but has a pair of opposed working ribs 11. The working rib 11 has an inclined surface 12 cut in one circumferential direction. On the other hand, the rotary slider 10 is made of a conductor as described below in order to be possible as a switching member for electrical connection.

A cam housing 30 fixed to the barrel 1 is disposed around the rotary slider 10. Eight guide ribs 33 are formed on the inner wall surface of the cam housing 30 so as to protrude from the inner wall surface of the cam housing 30 at regular intervals, and the rotary sliders are formed on the grooves between the guide ribs 33. The working rib 11 of 10 is guided and entered. The guide rib 33 has an inclined surface on the tip side to facilitate the positioning of the working rib 11. In the grooves between the guide ribs 33, stopping jaws 31 and 32 are formed to prevent the upward movement of the working rib 11. The lower stop jaw 31 is a retraction stop jaw corresponding to the retracted position of the writing lead 2, and the high stop jaw 33 is a stop jaw corresponding to the exposed position of the writing lead 2. 3 shows the profile of the cam portion as a developed view. The exposure stop jaw 32 and the retraction stop jaw 31 are alternately arranged between the guide ribs 33, respectively. Since the stop jaws are formed at an equiangular interval, the first exposure stop jaw 32a faces the third exposure stop jaw 32c, and the second exposure stop jaw 32b is opposite to the fourth exposure stop jaw 32c. It is located opposite. The retraction stop jaw 31 is also arranged in the same manner. Contact terminals 35 and 36, which will be described later, are provided in the pair of exposure stoppers 32b and 32d facing each other.

A driving member 20 for driving longitudinal sliding and rotation of the rotary slider 10 is disposed above the rotary slider 10. A triangular tooth 21 is formed on the tip side of the drive member 20. The teeth 21 are all four, and whenever they press the working ribs 11 of the rotary slider 10, the rotary slider 10 slides in the longitudinal direction of the barrel 1 and at about 45 degrees. It will make an angular rotation. The drive member 20 is also made of a conductor as described below to perform the power transfer function. The driving member 20 is coupled to the terminal member 50 through the screw portion 22 on the upper side, and the terminal member 50 is fixed to the button 42 housing the battery 43. As a result, the driving member 20 moves integrally with the button 42. A coil spring 41 is interposed between the cam housing 30 and the button 42 to constantly elastically push the button 42 in the direction in which the button 42 is exposed from the barrel 1. Accordingly, the button guide 40 for guiding the lifting and sliding movement of the button 42 is screwed to the upper end of the barrel 1 whenever the button 42 is pressed by the user.

By this mechanical configuration, whenever the button 42 is pressed against the elastic force of the spring 41, the teeth 21 of the drive member 20 come into contact with the actuating ribs 11 to rotate the rotary slider 10. At the same time pushing in the longitudinal direction, the inclined surface 12 and the teeth 21 of the working rib 11, the inclined surface acts to rotate the rotary slider 10 by 45.

As a result, the rotational movement of the rotary slider 10 is shown as a cross-sectional view in FIGS. 4 to 7. 8 to 11 are longitudinal cross-sectional views corresponding to FIGS. 4 and 7. With reference to these drawings, the electrical connection of the present light pen will be described in more detail.

The battery 43 housed in the button 42 is supported by the terminals 45 and 51 on the upper and lower sides, respectively. The upper terminal 45 is connected to the outer conductive portion 53 of the terminal member 50 through the conductive wire 46 along the inner wall surface of the button 42, the outer conductive portion 53 is a spring 41 made of a conductor Accordingly, it is electrically connected to the increasingly terminal 55 at the upper portion of the cam housing 30. The contact terminal 55 starts to fold in contact with the first conductor 5 attached to the inner wall surface of the barrel 1 starting from the LED unit 3 on the wall surface. As a result, the first conductor 5 is always in an electrically conductive state.

The lower terminal 51 of the battery 43 is electrically connected to the contact terminal 37 provided on the inner wall surface of the cam housing 30 through the driving member 20 made of a conductor through the contact spring 52. The contact terminal 37 is electrically integrated with the contact terminal 36 provided in the exposure stop jaw 32 region of the cam portion. On the other hand, the remaining second lead 6 from the LED unit 3 is attached to the inner wall surface of the barrel 1, the end portion of the lead wire 6, the end of the contact terminal extending inward of the cam housing 30 It is electrically connected with (36). This contact terminal 36 is located on the exposure stop 32d at a position opposite to the exposure stop 32b with the above-described contact terminal 35 (see FIG. 3). As a result, when the two contact terminals 35 and 36 are in contact with the rotary slider 10 at the same time, the second conductor 6 is in a conductive state.

In the state of FIGS. 4 and 8, since the actuating rib 11 is located on the retraction stops 31a and 31c, the writing core 2 is not exposed, and both contact terminals 35 and 36 are also rotating sliders ( The LED unit 3 does not emit light because it is not connected by 10). In this state, when the button 42 is pressed and released, the rotary slider 10 slides in the longitudinal direction by the driving member 20 and rotates 45 degrees while returning to the state of FIGS. 5 and 9. In FIG. 5 and FIG. 9, since the working rib 11 is located at the exposure stops 32a and 31c, the writing core 2 is exposed, but both contact terminals 35 and 36 are rotating sliders 10. As shown in FIG. The LED unit 3 does not emit light because it is not connected by. When the button 42 is operated again in this state, the state becomes as shown in FIGS. 6 and 10, and in FIGS. 6 and 10, as in FIGS. 4 and 8, the working rib 11 is withdrawn. The writing core 2 is not exposed, and the LED unit 3 does not emit light because it is located at the stops 31b and 31d.

When the button 42 is operated again in the states of FIG. 6 and FIG. 10, the state of FIG. 7 and FIG. 7 and 11, since the working ribs 11 are located at the exposure stops 32b and 31d, the writing core 2 is exposed, and both contact terminals 35 and 36 are rotating sliders 10. As shown in FIG. It is connected by the working rib 11 of. As a result, the LED unit 3 emits light. If the operation of the button 42 is repeated, the same procedure as described above is repeated.

Therefore, in the light-emitting pen according to the present invention, the writing core 2 is exposed at the time of one operation of the button 42, and simple writing is possible, and the writing core 2 retreats at the second operation, and at the third operation. There is exposure and illumination of the writing core 2 at the same time. In the fourth operation, the writing core 2 is withdrawn and the illumination is stopped, and the above process is repeated by repetition of the operation.

As described above, the light-emitting pen of the present invention provides an excellent effect that the selection of the writing lead and the illumination can be easily made since the operation of the writing lead retracting button and the switching operation of the light emitting member are linked.
