  Next, a process executed by the control unit 10 and will be described in detail with reference to FIGS. 3 and 4 when the search key 21 is operated (key pressing). FIG. 3 shows a flowchart for each step of processing executed sequentially by the control unit 10 of the wireless device 1. FIG. 4 exemplifies the transition of display items by search in the wireless device 1.

  As shown in FIG. 3, when the process is started by pressing the search key 21, measurement of the pressing time is started (step S11), whether or not the key is released is determined (step S12), and the pressed state is determined. If not released (step S12: NO), that is, if the search key 21 is kept pressed, it is determined whether or not the long press time preset in the storage unit 40 or the like has passed (step S12). S13) If the long press time has not elapsed, the process returns to step S12.

  By the determination processing in step S12 and step S13, the wireless device 1 is in a so-called short press operation state (step S12: YES) in which the press of the search key 21 is released without passing the set long press time. The so-called long press operation state (step S13: YES) after the long press time for which the search key 21 has been set can be determined (discriminating means).

  If it is determined that pressing the search key 21 is a long-press operation state (step S13: YES), the setting data stored in the storage unit 40 is read, and the currently set condition of the item to be searched Is changed in accordance with the switching order described above (step S14), and the process ends.

  By performing this step S14, for example, it is set as shown in FIG. 2B, and when the condition of the item to be searched that is currently set is “fixed station (↓)”, switching is performed. The condition to be searched is changed to “weather (↑)” set as the next condition in order.

  When it is determined that pressing the search key 21 is a short press operation state (step S12: YES), the setting data stored in the storage unit 40 is read, and the currently set item to be searched is determined. The reading position of the received data 41 is acquired from the condition and the item currently selected by the cursor or the like when the list of items is displayed on the display unit 30 (step S15).

  Next, the read position of the received data 41 is incremented in the search direction set as the condition of the item to be searched (step S16). For example, when items are arranged in the vertical direction in the list format of the received data 41 and the search direction is downward, the reading position is incremented to the downward item.

  Next, the received data 41 stored in the storage unit 40 is read based on the current read position (step S17), and it is determined whether or not the read item matches the set search condition. If not matched (NO), the process returns to step S16. In other words, when the search condition is “fixed station”, the search target item is incremented in the search direction set as the search condition until the item related to “fixed station” is searched.

  If the search condition matches in step S18, a list display of received data 41 based on the current read position, that is, a list display from the item of received data 41 that matches the search condition is performed (step S19). ,finish.

  That is, the wireless device 1 is in an operation state in which pressing of the search key 21 is a short press, and when the search execution is instructed, the processing of steps S15 to S19 is executed, so that the display unit 30 is operated before the operation. The received data 41 is searched with the search direction / search condition set from the cursor position of the item displayed in the list, and the list display from the matching item is performed by the search.

  For example, as shown in FIG. 4, when the display area R1 is displayed as a list on the display unit 30 before the operation, the cursor position is the item D1, and the set search condition is “fixed station”, the search is performed. By instructing execution of a search by pressing the key 21 for a short time, the item D2 that matches the item D1 is searched. The display unit 30 displays a list of display areas R2 to be displayed from the item D2.

  As described above, the wireless device 1 determines the operation state when operating the search key 21 for performing the search instruction input under the control of the control unit 10, and responds to any of the determined operation states. The condition of the item to be searched is set from the data of the plurality of items stored in the storage unit 40, and stored in the storage unit 40 with the set search condition according to the determined other operation state (for example, short press). The configuration is such that an item is retrieved from the retrieved data, and the data of the retrieved item is displayed on the display unit 30.

  For this reason, the wireless device 1 uses differently the setting of the condition of the item to be searched and the execution of searching for the item based on the set condition only by changing the operation state of the search key 21 which is the same operation key. Thus, even when the number of items to be displayed in a list increases, a desired item can be easily displayed without making a mistake in pressing the key.

  In addition, since the wireless device 1 displays the currently set search condition in the search condition display area G11 of the display unit 30, the search condition confirmation when the search of the item is executed by operating the search key 21 Can be easily performed.

  Further, since the wireless device 1 determines the operation state when the search key 21 is operated based on the difference in the key pressing time, the condition setting and the item to be searched for by a simple operation such as long key pressing / short pressing are performed. You can use different instructions such as search execution.

  In addition, the wireless device 1 sets the switching order of the condition of the item to be searched by the search condition setting screen G2 displayed on the display unit 30 and the operation from the operation unit 20, and the search key 21 selects the item to be searched. When the condition setting is instructed, the search condition is switched based on the set switching order.

  Therefore, even when there are a plurality of conditions for the item to be searched, the wireless device 1 uses the condition setting for the item to be searched and the item search execution in two operation states such as long press / short press. be able to.

  Note that the description in the above-described embodiment shows an example, and the present invention is not limited to this. The configuration and operation in the embodiment described above can be changed as appropriate.

  For example, in the present embodiment, the data of a plurality of items is exemplified by the received data 41 received from another wireless device, but is not limited to the received data. For example, data such as the setting position of the wireless device, the equipment name, and the date and time of the last call set in the items for each call sign name may be used.

  In addition to the weather information, the fixed station, and the location information, the data type in the reception data 41 exemplified in the embodiment may be an ID packet, a mobile station, model information, GPS data, or the like. The data format may also be a grid format, item format, DGPS (Differential GPS) format, or the like. The data communication format may also be a communication format using a communication protocol other than the APRS format.
