[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light indicating device. More specifically, the present invention is used, for example, at a conference or a lecture to indicate an explanation place or a corresponding place using visible light, or to indicate an object at a remote place by visible light. The present invention relates to a light indicating device used for the above.

[0002]

2. Description of the Related Art In recent years, slides, OHPs (overhead projectors), white boards, and the like are often used as auxiliary devices in lectures, briefings, conferences, and the like. When explaining a chart or the like using these auxiliary devices, a pointing rod or an optical pointing device is used to indicate a description place.

FIG. 3 shows a conventional light pointing device (pointer) 51.
Is shown. When the light indicating device 51 is turned on by operating the switch 52, a light beam 54 is emitted from the light projecting window 53, and the light beam 54 is projected from a distant position by projecting the light beam 54 to a designated portion. Can point to a place.

[0004]

[Problems to be Solved by the Invention] When the above-mentioned optical type light indicating device is reduced in size and becomes handy, each person holds the light indicating device at a conference or a presentation. There is also. Moreover, even in such a case, a writing operation such as taking a memo is often required.

However, in the above-described light indicating device, a writing instrument is prepared on a table together with the light indicating device.
The light indicating device and the writing instrument had to be changed and used as needed. For this reason, there are drawbacks such as being bulky in a mobile phone and taking a place on a table to be in the way. In addition, it is troublesome to switch between the light indicating device and the writing implement each time it is used, and there is a problem that writing cannot be performed quickly.

The present invention has been made in view of the above-mentioned drawbacks of the conventional example, and has as its object to improve the usability of both by integrating the light indicating device and the writing instrument. .

[0007]

The light indicating device of the present invention is
In a light indicating device for indicating a pointing object or a pointed position by emitting visible light in a pointing direction, a writing instrument is integrally attached to a main body of the light indicating device that emits visible light.

[0008]

According to the present invention, the writing instrument is integrated into the main body of the light indicating device that emits visible light, so that it is not necessary to change the light indicating device and the writing instrument each time it is used. Switching to the operation can be performed smoothly, writing can be performed quickly, and the instruction operation can be performed quickly. Further, since the light indicating device and the writing instrument are integrated into one, the device does not become bulky when carrying the device and is less likely to be disturbed on the table. In addition, it is no longer impossible to take notes because of forgetting the writing instrument.

FIG. 1 shows a light indicating device 3 according to an embodiment of the present invention.
1 is a sectional view of FIG. The light indicating device 31 is composed of a light indicating device main body 21 and a writing instrument 22, and has a pencil-shaped outer shape having an appropriate thickness in consideration of ease of use when handwriting and writing. The light indicating device main body 21 includes a light emitting element 1 such as a semiconductor laser element or a light emitting diode that emits visible light, and a refractive lens 2 that focuses or collimates a light beam (visible light) α emitted from the light emitting element 1.
And a driving battery 3 such as a dry battery, a driving circuit 4 for driving the light emitting element 1, and a contact 5 for turning on and off the driving circuit 4 are housed in a case 6, and an operation for opening and closing the contact 5. A switch 7 is provided on the surface of the case 6, and an emission port 8 is opened in the case 6 so as to face the lens 2. In addition, a glass plate or the like for protecting the lens may be provided in the emission port 8.

When the light indicating device 31 is grasped by hand and the switch 7 is pressed, the contact 5 is closed, the drive circuit 4 is turned on, and the light emitting element 1 is driven to emit the light beam α. Therefore, the designated position or the like can be indicated by irradiating the designated position or the designated object with the light beam α.

On the other hand, the writing implement 22 includes a writing implement main body 10 such as a ballpoint pen, a mechanical pencil, a fountain pen and the like in the holder 9.
It is the one that paid. Of course, these writing implements 1
Numeral 0 is designed so that it can be taken out of the holder 9 when refilling a ball-point pen, mechanical pencil lead, ink or the like. Further, the outer surface of the holder 9 may be subjected to knurling for non-slip or a non-slip member may be attached.
The writing implement 22 may be of a knocking type or a capping type in which the writing implement main body 10 is retracted so that ink or the like does not adhere to clothes or the like when carried. In the case of the cap type, if the cap is put on the light exit port 8 side of the light indicating device main body 21 at the time of writing, there is no danger that the light beam α is emitted toward the eyes even if the switch 7 is touched carelessly. .
Further, a clip may be provided so that the clip can be inserted into a breast pocket or the like.

In the embodiment shown in FIG. 1, the case 6 of the light indicating device main body 21 and the holder 9 of the writing instrument 22 are integrated by, for example, integrally forming a resin. However, if the case 6 and the holder 9 which are separate from each other are connected, for example, by screwing, the writing instrument 22 is separated from the optical pointing device main body 21 when the writing instrument 22 is unnecessary,
The light indicating device main body 21 can be carried and used alone.

Thus, when the writing operation is started from the state where the light indicating device main body 21 is used, the writing can be immediately performed using the writing tool 22 of the light indicating device 31 which is being held. If it is not necessary to replace the light indicating device main body 21 with the writing instrument 22 in this way, when the speaker must be used while listening to the talk of the speaker, the content of the lecture by the speaker is less likely to be missed.

FIG. 2 is a sectional view of the light indicating device 32 according to another embodiment of the present invention. In this embodiment, a micro Fresnel lens 11 is used to focus or collimate a light beam α emitted from a light emitting element 1.

[0015]

[Effects of the Invention] According to the present invention, since the light indicating device main body and the writing implement are integrated, there is no need to change the light indicating device and the writing implement each time.
Alternatively, it is possible to switch from instruction to writing. In addition, the appearance is smarter, the phone is less bulky, and less obstructed on the table. In addition, there is an advantage that it is not impossible to take a memo by forgetting the writing instrument.
