     DETAILED DESCRIPTION OF THE INVENTION  
     [0014] Referring now to FIGS. 1 and 2, the FIGS. 1 and 2 show a schematic construction of the wearable wrist watch means having function for detecting unlawful recorded radio audio/video signals of a preferred embodiment in accordance with the present invention. The wrist watch means  1  includes a housing  10 , a control circuit unit  11 , a display unit  12 , a memory unit  13 , an input unit  14 , a chronometer  15 , a battery  16 , a toggle switch (or a frequency regulation button) and a radio multi-frequency scanner  17  having a radio frequency scanning unit  18  and a frequency modulation unit  19 .  
     [0015] As shown in the figures, the housing  10  defines a space to contain corresponding parts; the control circuit unit  11  is disposed in the housing  10  for data processing and activating correspondent components, the control circuit unit  11  will be described hereinafter; the memory unit  13  is also mounted in the housing  10  to store data that can be pre-stored in the memory unit  13  or downloaded into the memory unit  13  from additional electronic devices (not shown) through a transmitting interface, the data can be a configuration of images, characters and datum; a user can operate a control key  23  to input a data and a control signal to the input unit  14 , then the input unit  14  outputs the same to the control circuit unit  11 , the control circuit unit  11  is functioned to execute data processing, timing and control corresponding activity of corresponding component upon a determined mode entered by a selective key  22 .  
     [0016] The display unit  12  can be a liquid crystal display or the like, used for showing the time and the data as mentioned-above, wherein the data is controlled by the operation of the selectable switch  22  through the control circuit unit  11 . The chronometer  15  provides a data of timing and the data is presented in the display unit  12  during the timing mode being selected. The power supply  16  (battery) applies an operating voltage to corresponding components for executing corresponding functions.  
     [0017] In addition, the wearable wrist watch means  1  according to the present invention further contains a radio multi-frequency scanner  17  having a radio frequency scanning unit  18  and a frequency modulation unit  19  for scanning and detecting a frequency of a radio signal in which the radio frequency scanning unit  18  catches a radio signal which is to be detected in accordance with a predetermined sampling time, then, the frequency of the radio signal is demodulated by the frequency modulation unit  19  and, appeared in the display unit, the radio frequency scanning unit  18  and the frequency modulation unit  19  can be formed into a miniature module by a micro electromechanical technology; An extensible antenna  21  can be optionally provided on the watch means  1  so as to correspond to a frequency to be detected; and a toggle switch  20 , which is used to regulate band width of the frequency and input data, that is, the toggle switch  20  can be functioned as either a regulation button for controlling band width of the frequency modulation unit  19  or a input button for input of data, however, if necessary, the toggle switch  20  can be constructed to contain additional functions such as to operate for exchanging frequency display, display of period, auto-locked, temporary-store and display, therefore, number of operative keys on the watch means  1  will be reduced so as to be convenient in operation and clear in construction.  
     [0018] Moreover, a buzzer (not shown) can be further provided in the watch means  1 , the time interval of intermittent operation of the buzzer upon the detected signal strength of the radio frequency will be variable, an indication of the distance between the user and the detected signal source is obtained therefrom.  
     [0019] An interaction between the control circuit unit  11  and each component will be described hereinafter. Initially, one specific mode of multi-modes including timing mode, input mode and test mode can be selected by the selective key  22 . In case of the timing mode is selected, a timer function will be appeared on the display unit  12  by virtue of the operation of the control key  23  through the control circuit unit  11 . When the input mode is selected, a data is input and updated over the input unit  14  to execute data processing, to cause the data storage in the memory unit  13 , and to instruct the display unit  12  to show the corresponding data; and, when the test mode is selected, selectable functions such as display of exchangeable frequency, display of period, auto-locked and the temporary store together with display of the detected radio frequency, used for detection of radio frequency can be controlled by the control key  23  and the toggle switch  20  through the control circuit unit  11 .
