Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prompter device that assists a speaker to speak at a lecture, for example, and more specifically, it reflects the image of the speech on a half mirror so that the speaker can see it visually. It is related to the prompter device that can be confirmed.

[0002]

[Prior art]

 In a conventional prompter device, for example, as shown in FIG. 5, the output of a personal computer 1 is connected to an LCD display device 3 with a backlight via an electric signal line 2. A half mirror 4 is arranged above the LCD display device 3 at an angle of 45 ° with respect to the screen. Further, the LCD display device 3 is arranged on the desk, while the personal computer 1 is arranged at a position away from the desk, preferably in a position invisible to the audience, and a predetermined operation is performed there.

Then, based on the output command of the personal computer 1, character information obtained by reversing the sentence of the utterance content is displayed on the screen of the LCD display device 3 in a scrolling or page-changing manner. Then, by using the light of the backlight installed behind the screen of the LCD display device 3, the half mirror 4 is illuminated with the content of the statement output on the screen of the LCD display device 3. Then, the half mirror 4 reflects and the characters of the utterance contents are inverted and brought into a normal state, so that the speaker visually presents the image concerned. As a result, the speaker can prevent the wrong effects such as typographical errors and forgetting to say the contents.

Since the personal computer 1 operates the image for reflecting the utterance contents on the half mirror 4 directed to the speaker, an operation such as scrolling is easily performed, and the half mirror is turned on. Since it is used, the audience can see the appearance of the speaker because it looks just like a transparent board.

[0005]

[Problems to be solved by the device]

 However, in the above-described conventional prompter device, the personal computer 1 itself has a display device necessary for processing an output command and the like, and an LCD display device 3 for irradiating the half mirror 4 with inverted message contents. Need two displays. Since the LCD display device 3, which is one of the display devices, is configured to reflect the displayed text on the half mirror 4 and send it to the speaker, it is necessary that the LCD display device 3 has the same size as the half mirror 4. Since such a large LCD display device 3 is placed on the desk of the lecturer, a space is required for placing materials used by the lecturer. Further, the image displayed on the LCD display device 3 is upside down, leftward and rightwardly reversed, which makes it difficult for the lecturer to read, and is unnecessary and annoying to the lecturer.

Further, since the personal computer 1 and the LCD display device 3 are connected by the electric signal line 2, they are easily affected by an external electromagnetic field, and the internal resistance of the electric signal line itself causes a loss. Long distance transmission is not possible. Therefore, it may not be used in a large venue where the distance between the desk on which the LCD display device 3 is placed and the operator of the personal computer 1 becomes long, or it may be operated in a place visible to the audience. It's bad.

Further, since the LCD display device 3 has a flat plate shape, its screen is directed upward (in a direction orthogonal to the desk top surface), and its angle adjustment becomes difficult.

The present invention has been made in view of the above background, and an object of the present invention is to solve the above problems, downsize a display device for sending an image to a half mirror, and place it on a speaker's desk. The area of the equipment to be installed is reduced as much as possible, and when performing processing such as long-distance transmission of speech content, that is, screen scrolling, remote control is possible, regardless of the presentation location, and half mirror An object of the present invention is to provide a prompter device capable of easily adjusting the irradiation angle to the eye.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the prompter device according to the present invention, a control unit for sending out the character information of the utterance content, a display device for imaging the character information, and a lens for condensing the image light are combined. The light transmitting section that has the optical fiber that transmits the image transmitted from the light transmitting section, the light emitting section that expands the image transmitted by the optical fiber by a lens, and emits the image. The image is reflected so that it can be viewed with a half mirror installed at a predetermined position and at a predetermined angle.

Further, preferably, a liquid crystal screen with a backlight is used as the display device provided in the light transmitting section. A CRT may be used instead of the liquid crystal screen with a backlight. More preferably, the optical fiber is configured by bundling a plurality of fibers.

[0011]

[Action]

 The control unit operates the character information of the document, and the inverted character information is displayed by the display device provided inside the light transmitting unit. Then, the displayed image is condensed by the lens and is incident on the optical fiber. Since the optical fiber has low transmission loss, long-distance transmission is possible.The image is transmitted from outside the listener's field of view by the optical fiber to the light emitting part, and the lens provided in the small light emitting part enlarges the image and emits it. To do. Then, the emitted image is reflected on the half mirror so that it is reflected in a normal state. Therefore, the speaker will make a presentation while watching the content of the remarks displayed on the half mirror. When an optical fiber formed by bundling a plurality of fibers is used, a larger amount of light and a large amount of image information will be sent.

[0012]

【Example】

 Hereinafter, preferred embodiments of a prompter device according to the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the character information of the utterance content operated by the personal computer 10 is converted into an electric signal and sent to the light transmitting device 12 via the electric signal line 11. Then, based on the sent character information, an image is formed using the display device provided in the light transmitting device 12.

The light transmitting device 12 will now be described. As shown in FIG. 2A, the light transmitting device 12 is composed of a small liquid crystal screen 14 with a backlight 13 and a lens 15, and is transmitted by the personal computer 10. The received character information is displayed on the liquid crystal screen 14 which is a display device. Since the liquid crystal itself does not emit light, the image displayed on the liquid crystal screen 14 cannot enter the optical fiber 16 as it is. Therefore, the backlight 13 is applied from behind the liquid crystal screen 14, and the image light generated by the light is condensed through the lens 15 and is incident on the optical fiber 16 for image transmission.

On the other hand, as another configuration of the display device, a small CRT 17 and a lens 15 may be configured as shown in FIG. By using a small CRT 17 for the display device, it is possible to generate image light without illuminating the backlight 13 from the back of the screen, condense it with the lens 15 and send it to the optical fiber 16.

When displaying an image on the liquid crystal screen 14 and the CRT 17, the personal computer 10 converts the characters of the utterance contents into reverse characters in advance and displays the image by the reverse characters.

Further, as described above, the output of the light transmitting device 12 is incident on the optical fiber 16, and the other end of the optical fiber 16 is connected to the light emitting device 18 arranged on the desk. As a result, the image displayed on the display device (liquid crystal screen 16, CRT 17) is sent to the light emitting device.

Here, the optical fiber 16 is used for transmission because the optical fiber is not easily affected by external conditions (electrical induction by other power equipment etc.) and the transmission loss is small. This is because when the personal computer 10 is placed, video transmission can be performed even if the location is a long distance.

As shown in FIG. 3, the light emitting device 18 is provided with a lens 19 attached to the tip of the optical fiber 16 so as to be movable forward and backward in the axial direction. It has a moving mechanism.

A half mirror 20 is arranged in the emitting direction of the light emitting device 18 (see FIG. 1). As a result, the image transmitted by the image is magnified and emitted by the lens 19, irradiated on the half mirror 20 adjusted to a predetermined angle at a predetermined position, and reflected by the half mirror 20 to invert the vertical and horizontal directions. , Moves the character forward. Then, the speaker will make a presentation while visually recognizing the image (content of the statement) reflected on the half mirror 20. The magnification of the characters can be adjusted by moving the lens 19 back and forth in the optical axis direction.

In this way, in this example, since the image of the utterance content is finally enlarged by the light emitting device 18, even if the characters displayed on the liquid crystal screen 14 and the CRT 17 are small (they may be so small that they cannot be visually recognized). Since it does not matter, a small size can be used, and the light transmitting unit 12 can be downsized. In addition, if the size is reduced in this way, the surroundings of the characters may become jagged when the enlargement ratio of the light emitting device 18 is large, but it is sufficient if the characters can be recognized and the amount displayed at one time is one to several lines. Therefore, the miniaturization can be done without any problem.

Further, since only the small light emitting device 18 exists on the desk, the speaker can make use of the material such as placing the material in the empty space on the desk. Since the light emitting device 18 is a cylinder attached to the tip of the optical fiber 16, its direction can be changed to an arbitrary direction, and an image of the content of the statement can be emitted in a desired direction.

The optical fiber 16 actually has a structure in which a plurality of fibers 21 are bundled as shown in FIG. This makes it possible to increase the amount of image light, or send a large amount of image information to send a clear image to the speaker.

[0023]

[Effect of device]

 As described above, in the prompter device according to the present invention, since the content of the utterance is finally expanded by the lens provided in the light emitting device, the characters displayed on the display device such as the liquid crystal screen and the CRT can be made small. It will be possible. As a result, the light transmitting device and the light emitting device can be downsized. At that time, when the magnification of the light emitting part is large, the periphery of the image light characters may become jagged, but it is sufficient if it can be recognized as characters, and the amount displayed at one time is one to several lines. The miniaturization can be done without any problem.

Since a small light emitting device can be installed on the desk instead of the display device which has conventionally been required to have the same size as the half mirror, there is a space on the desk of the speaker, and the material can be stored. Effective use such as placing can be achieved. Also, since the light emitting unit is small and is composed of a lens, etc., it is possible to easily adjust the irradiation angle to the half mirror, and by changing the angle of the half mirror accordingly, the angle can be adjusted so that it is easy for the speaker to see. It will be possible.

Further, the character information of the edited document is sent to the light transmitting device by the controller performing a predetermined operation, and the image displayed there is transmitted by the optical fiber. As described above, since it is not affected by the external electromagnetic field and there is no transmission loss due to the internal load, it is possible to transmit video over a long distance. Therefore, it is possible to perform image control (scrolling, etc.) by installing a control unit at a position invisible to the audience and performing remote control there.

Furthermore, when the optical fiber structure is formed by bundling a large number of fibers, the amount of light of the image sent to the lecturer can be increased and a large amount of image information can be transmitted. , Can send a clear image.
