FIG. 2 is a block diagram of the essential parts of an embodiment of the information retrieval apparatus according to the present invention. In the figure, (a) is the input unit side and (b) is the display unit side. On the input section side (a), 11 is an input section, 12 is a modulation / transmission section, and 13 is a control section. Input section
11 is composed of a touch panel, and inputs are made by pressing the fingertip.
Reference numeral 12 is a modulation / transmission unit, which is controlled by the control unit 13 and has an input unit.
The signal from 11 is amplified to an appropriate signal level, modulated into a required high frequency signal, and transmitted from the antenna 14 as a weak radio wave.

Reference numeral 15 on the display section side (b) is an antenna for catching radio waves emitted from the antenna 14 on the input section side (a). A reception / demodulation unit 16 receives and demodulates the signal captured by the antenna 15. A menu storage unit 17 stores a menu for information retrieval. An information storage unit 18 stores guidance information and the like corresponding to each menu. A discrimination unit 19 compares the signal input from the input unit side (a) via the reception / demodulation unit 16 with the data read from the menu storage unit 17, discriminates the corresponding menu, and the information storage unit 18 The information corresponding to this menu is discriminated from the read data. A display unit 20 displays on the screen based on the signal from the determination unit 19. twenty one
Is a storage unit that stores a control program of the apparatus. A control unit 22 controls each unit on the display unit side (b).

FIG. 3 is a block diagram of essential parts of another embodiment of the information retrieval apparatus according to the present invention. 31 on the input side (a) in the figure
Is an infrared light emitting unit, which is controlled by the control unit 13 and
Emits a signal from infrared rays. A light receiving unit 32 on the display unit side (b) receives the infrared light from the infrared light emitting unit 31, converts the infrared light into an electric signal, and outputs the electric signal. The other reference numerals are the same as those in FIG.

Next, the operation of the information retrieval apparatus according to the present invention will be described. First, in the case of FIG. 2, on the display unit side (b), by the program read from the storage unit 21 via the control unit 22,
Display unit based on the data read from the menu storage unit 17
Display the search menu at 20. The display unit 20 is the screen of the display unit 4 of FIG. 1, and is installed at a position close to the window glass (C) as shown in FIG. To do. Then, a transparent touch panel (1 shown in FIG. 1) of the input unit 11 is attached in front of the screen of the display unit 20 with the window glass (C) interposed therebetween.

The search menu displayed on the display unit 20 is referred to, and the menu is designated by a touch operation on the touch panel.
For example, as shown in FIG. 4, the input unit 11 for inputting the designation of the search menu detects the touched position of the touch panel 41 by the touch position detection unit 42, and outputs this signal via the control unit 13. To configure. The signal from the input unit 11 is input to the modulation / transmission unit 12, amplified to an appropriate signal level, the required high frequency signal is modulated by this signal, and emitted from the antenna 14 as a weak radio wave. Radio waves from the antenna 14 enter the building through the windshield and are caught by the antenna 15,
It is input to the reception / demodulation unit 16 and is received / demodulated. The demodulated signal is input to the discrimination unit 19 via the control unit 22, and the discrimination unit 19
The data read from the menu storage unit 17 via the control unit 22 determines the menu corresponding to the touched position. The information read from the information storage unit 18 via the control unit 22 is used to determine the information corresponding to this menu, the data of the determined information is input to the display unit 20, and the required display signal is generated. Switch the displayed search menu to this screen.

In the case of FIG. 3, the signal from the input unit 11 is input to the infrared light emitting unit 31, amplified to an appropriate signal level, and then the LED
It drives (light emitting diode) and outputs it by infrared rays. A signal from the infrared light emitting section 31 passes through the window glass (c) and enters the light receiving section 32, is converted into an electric signal by a phototransistor or the like, and is input to the discrimination section 19 via the control section 22.
The other operations are the same as in the case of FIG.

As described above, since the signal from the input unit 11 (touch panel 1) is wirelessly transmitted in the window glass, it is convenient not to use the commercial power source for the device outside the window glass. Is. For this purpose, for example, each device may be operated by a primary battery, but maintenance of battery consumption is required. Therefore, as shown in FIG. 5, the window glass (C)
The light source 51 is provided on the inner side b of the solar cell 52, and the solar cell 52 is disposed on the outer side a of the window glass (c) at a position facing the light source 51.
The power generated by the solar cell 52 is supplied to each device. Alternatively, the electric power generated by the solar cell 52 is stored in a secondary battery (battery) and simultaneously supplied to each device. It should be noted that this solar cell 52 may be provided on the outer surface side as well, and sunlight may be received during the day to generate electric power even in the sunlight.

[0014]

As described above, according to the information retrieving apparatus of the present invention, the display device in the window glass is operated by touching the touch panel on the outer surface of the window glass to retrieve information. For example, the display device can be operated without worrying about theft or damage caused by mischief even at night or on holidays when there is no supervisor, and it is useful for information provision service to customers or sales promotion by providing product information. It can be useful.
