Japanese Patent Laid-Open No. 11-284540

  On the other hand, in the conventional wireless communication device, the frequency band that the user wants to use can be selected from all frequency bands that can be used by the wireless communication device, and each time a key operation, for example, the A key is pressed, is sequentially performed. The frequency band was called up and the frequency band was set and the frequency band was displayed. For example, frequency band used: 118 MHz → A key pressed → 144 MHz → A key pressed → 220 MHz → A key pressed → 300 MHz → A key pressed → 430 MHz (→ A key pressed → 118 MHz). In this way, if the setting of the used frequency band is to be changed from 118 MHz to 300 MHz, it is necessary to press the A key three times.

  This will be described with reference to the flowchart in FIG. That is, when the A key is pressed from the normal state (118 MHz display) (step S11), the frequency band (144 MHz display) to be displayed next is retrieved from the memory (step S12). If the frequency band (144 MHz display) is found as a result of the search (step S13), the frequency band is called (step S14), the frequency band is displayed on the display, and the transmission / reception frequency band is set as the display frequency band. (Step S15). If no frequency band (144 MHz display) is found as a result of the search in step S13, the search is terminated, and the currently displayed frequency band (118 MHz display) is displayed and set as it is. This is repeated until the target frequency band (for example, 300 MHz display) is displayed and set.

  However, in the setting and display of the frequency band by the conventional method as described above, it is necessary to sequentially set and display the frequency band that is not used until the target frequency band is set and displayed by pressing the A key. For this reason, there is a problem in that the number of key operations required to call a target use frequency band increases.

  It is an object of the present invention to provide a wireless communication device that reduces the number of key operations required to set and display a target frequency band.

  The wireless communication device according to claim 1 of the present invention includes a display, a first key that designates a mask frequency band in the usable frequency band in advance, and information on a mask frequency band designated by the first key. A memory for storing information on each frequency band of the usable frequency band, and a frequency band from the usable frequency band excluding the mask frequency band every time the second key is pressed, sequentially from the memory, in ascending or descending order, A display based on the searched frequency band is displayed on a display, and a frequency display and frequency setting control means for setting a transmission / reception frequency band to the display frequency band are provided.

  According to the wireless communication device of the first aspect of the present invention, the frequency band mask-designated by the first key is not displayed by the operation every time the second key is pressed, and of course, the frequency band is not set. This is not done, the number of key operations is reduced, and the operation is simplified. In addition, the setting can be customized, and the search time for the frequency band for display is shortened.

  Embodiments of a wireless communication device according to the present invention will be described below.

  FIG. 1 is a block diagram showing a configuration of a wireless communication device according to an embodiment of the present invention.

  As shown in FIG. 1, a wireless communication apparatus according to an embodiment of the present invention includes a transmission / reception circuit 1, an antenna 2, a microcomputer 3 that controls the transmission / reception circuit 1 and performs display control and setting control for setting a frequency band. , A memory 4 for storing information including a usable frequency band and a mask frequency band, a first key for designating a frequency band to be masked, and an A key 5 corresponding to a second key for designating the used frequency band each time the key is pressed. A key group 7 including a mask instruction key 6 corresponding to the key, and a display 8 including a display of a used frequency band.

  The microcomputer 3 functionally stores in advance the frequency band information that is not used in the usable frequency band in response to an instruction from the mask instruction key 6 and removes the mask frequency band every time the A key 5 is pressed. Search frequency bands from the available frequency bands in order from the memory in ascending or descending order, display the display based on the searched frequency bands on the display unit 8, and set the transmission / reception frequency band as the display frequency band. Control means.

  The display of the frequency band in the wireless communication device according to the embodiment of the present invention will be described.

  The frequency band to be masked is designated by the mask instruction key 6. For example, “144 MHz: USE” → “144 MHz: MASK”, “220 MHz: USE” → “220 MHz: MASK” is designated by the mask instruction key 6. As a result, information indicating that the 144 MHz and 220 MHz frequency bands are masked from the usable frequency bands stored in the memory 4 is stored.

  Subsequently, each time the A key 5 is pressed, the frequency band is called sequentially, and the frequency band is set and displayed. For example, the frequency band used: 118 MHz → A key pressed → 300 MHz → A key pressed → 430 MHz (→ A key pressed → 118 MHz) is set and displayed every time the A key 5 is pressed. In this case, 144 MHz and 220 MHz frequency bands Is masked. Therefore, if it is attempted to change the setting from the frequency band 118 MHz to 300 MHz, it has been necessary to press the A key 5 three times in the conventional case, but this is only required once.

  Further, in the designation of the frequency band to be masked by the mask instruction key 6, “144 MHz: MASK” → “144 MHz: USE”, “220 MHz: MASK” → “220 MHz: USE” is designated, and the result is stored in the memory 4. The masking of the 144 MHz and 220 MHz frequency bands in the available usable frequency band is released, and the conventional operability is restored.

  Next, frequency band setting display in the wireless communication apparatus according to the embodiment of the present invention will be described based on the flowchart of FIG.

  When the A key 5 is pressed from the normal state (118 MHz display) (step S1), the frequency band (144 MHz display) to be set and displayed next is retrieved from the memory (step S2). If no frequency band (144 MHz display) is found as a result of the search, the search is terminated, the currently displayed frequency band (118 MHz display) is displayed as it is, and the transmission / reception frequency band is also maintained as it is.

  If a frequency band (144 MHz display) is found as a result of the search in step S2 (step S3), it is checked whether or not the frequency band is masked (step S4). A frequency band (144 MHz display) is called (step S5) and displayed on the display 8, and a transmission / reception frequency band is set as the display frequency band (step S6). When it is determined in step S4 that the frequency band is masked, the memory 4 is searched again for the frequency band (220 MHz display) to be displayed next. Here, the band mask is checked again, and this process is repeated until the target frequency band (300 MHz display) is found. When the target frequency band is found, the target frequency band (300 MHz display) is displayed on the display 8. The transmission / reception frequency band is set as the display frequency band.

  As described above, when the frequency band (144 MHz) and the frequency band (220 MHz) are masked, the operation of the A key 5 is performed only once.

  As described above, according to the wireless communication apparatus according to the embodiment of the present invention, the frequency band to be used and the number of times the A key is pressed at the time of display are reduced, and the troublesomeness is eliminated. In addition, since unnecessary frequency bands are not displayed, the operation is simplified. In addition, in a wireless communication device that can be operated in two frequency bands at the same time, the number of key presses is further increased, so that the operability can be further improved by applying the present invention.

  Further, not only the setting and display of the frequency band but also the setting display can be simplified by preventing the unnecessary setting items from being displayed to the user. Further, the setting and display change may be performed by remote control.
