[0010] The casing 20 is attached to the arm 31, and the arm 31 is attached to the holder 7, so that the display device 4 is held by the holder 7 via the arm 31. The arm 31 is swingably connected to the holder 7 around a first swing shaft 31a along the short direction of the holder 7, and swings around a second swing shaft 31b parallel to the first swing shaft 31a. It is connected to the casing 20 as much as possible. Thereby, the display device 4 can be swung with respect to the holder 7, and by the swing, the distance between the eyes of the user 8 holding the holder 7 and the display device 4 and the distance between the holder 7 and the display device 4 are determined. The relative angle can be changed. Further, the display device 4 is attached to the holder 7 by the swing,
It can be made compact for convenient carrying.

The drive circuit 23 is built in the casing 20 and the arm 31 and drives the display 21 according to the image signal sent from the control device 3 and drives the inverter 25 to turn on the backlight 22. Thereby, the display 21 generates an image corresponding to the signal sent from the control device 3 based on the voice recognition, and emits the image display light as shown by the dashed line in FIG.

The optical system 24 is constituted by optical elements such as a combiner and a total reflection mirror, and changes the optical path of the image display light emitted from the display 21. The optical system 24 transmits the image display light whose optical path has been changed to the holder 7.
Is located at a position guided to the eyes of the user 8 holding the camera. Thereby, the display image of the display device 4 is visually recognized by the user holding the holder 7. In the present embodiment, by oscillating the display device 4 with respect to the holder 7 as described above, the arrangement of the display device 4 with respect to the holder 7 can be adjusted. The optical system 24 is arranged farther than the display 21 for the user.

In this embodiment, the optical system 24 is a single plate-like material, and the optical path changing surface is a concave surface along the aspherical surface. The image display light whose optical path is changed by the optical system 24 and guided to the user's eyes forms an enlarged virtual image farther than the display 21 for the user.
The shape of the light path changing surface is determined. The optical system 2
When the combiner 4 is constituted by a combiner, light from the front can be transmitted, and the user can visually recognize both the display image and the real entity in the front. The combiner can be constituted by a half mirror or a hologram element. When using a half mirror, the optical path of image display light is changed by reflection,
When a hologram element is used, the optical path of the image display light is changed by diffraction. The optical system 24 is attached to a first support piece 26a, and the first support piece 26a is attached to a second support piece 26b attached to the casing 20 by a third support member 26b extending in a direction perpendicular to the second swing shaft 31b. The swing shaft 26c is swingably connected to the center, and the swing can adjust the position of the optical system 24. Note that the optical system 24 may be composed of a plurality of optical elements.

The microphone 5 is provided on the casing 20 of the display device 4, and is held by the holder 7 via the casing 20 and the arm 31. Note that a voice input microphone may be provided so as to be directly held by the holder 7.

The switch 6 is of a push button type and is arranged at a position where it can be operated by fingers of a user 8 holding the holder 7. The control device 3 outputs a voice input control signal according to the operation of the switch 6. For example, when the switch 6 is continuously pressed for a certain period of time or longer, the control device 3 of the sound taken in from the microphone 5
A voice input control signal for turning on the recognition function is output, and when the finger is released from the switch 6 and the switch 6 returns to the original position by the elasticity of a spring or the like, the sound for turning off the voice recognition function is output. Outputs the input control signal. Further, the control device 3 and the switch 6 are connected via a communication port conforming to RS232C or the like, and communication software for inputting a signal corresponding to the number of times and the operation time of the switch 6 to the control device 3 is controlled. By storing the information in the device 3, control corresponding to the operation of the switch 6 may be performed. For example, when the switch 6 is pressed twice consecutively, the control device 3 outputs an image signal for displaying a candidate for conversion of hiragana into kanji, katakana, etc., displayed on the display device 4 based on the voice recognition. Then, when the switch 6 is pressed twice again, an image signal for displaying another conversion candidate of the hiragana is output, and when the switch 6 is pressed once within a short time, voice recognition is performed. A space for one character is stored in place of a character, and when the switch 6 is pressed three times in succession, the hiragana is stored as a hiragana without conversion, thereby providing an auxiliary function of document creation.

The pointing device 47 is of a trackball type, is composed of a trackball 47a and a click button switch 47b, and is arranged at a position where it can be operated by the fingers of the user 8 holding the holder 7. The control device 3 includes the pointing device 4
A signal corresponding to a cursor image that moves in accordance with the operation of No. 7 and a signal for selecting display contents in accordance with the operation of the click button switch 47b are output. For example, by operating the click button switch 47b, a signal for determining a conversion candidate of hiragana displayed on the display device 4 based on the voice recognition is output. Note that a joystick type or a pad type may be used as the pointing device 47.

As shown in FIG. 2, by holding the holder 7 and arranging it on the side of the head of the user 8, the casing 20 of the display device 4 is arranged in front of the face of the user 8, and
The image display light emitted forward from 1 is redirected by the optical system 24 to be guided to the eyes of the user 8, the microphone 5 is positioned near the front of the mouth of the user 8, and the switch 6 is used in the holder 7. By being arranged on the back surface on the side opposite to the user 8, the operation can be performed with the fingers of the user 8 holding the holder 7. That is, the user 8 holding the holder 7
Of the display image on the display device by the
Of the voice generated by the user 8 holding the camera 7 from the microphone 5 and the user 8 holding the holder 7
The positions of the display device, the microphone 5, and the switch 6 with respect to the holder 7 are determined so that the operation of the switch 6 with the fingers can be performed simultaneously.

According to the above configuration, by holding the holder 7, the switch for controlling the visual recognition of the image corresponding to the voice input generated by the display device 4, the capturing of the voice from the microphone 5, and the voice input control. 6 can be performed simultaneously, and the operability can be improved. Further, the image displayed on the display 21 can be enlarged and formed farther to the user 8 than the display 21, and the operability of voice input can be improved by making the image easier to see.

The present invention is not limited to the above embodiment. For example, a reflective liquid crystal display, a CRT display, or the like may be used as the display. Further, the control device may be built in the holder. Further, the voice input support device of the present invention may be mounted on the head of the user. For example, a head-mounted band-type fixing device 70 shown by a two-dot chain line in FIG.
Is connected to the holder 7. Further, as shown by a two-dot chain line in FIG. 3, a second audio input microphone 5 ′ that is arranged apart from the microphone 5 is connected to the control device 3, and both microphones 5,
By comparing the waveform and the phase of the voice input from 5 ′ and extracting and recognizing only voices having the same waveform and a phase difference corresponding to the time difference between voice input from both microphones 5 and 5 ′,
A noise canceling function may be performed.
