Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a wireless public line network,
The present invention also relates to an input device applicable to a mobile wireless terminal device used in a private wireless network, and a mobile phone device using the input device.

[0002]

2. Description of the Related Art In recent years, wireless public lines have become widespread, and there is an increasing demand for miniaturization of wireless terminal devices that are supposed to be carried and used. In addition to voice communication, communication of characters, images, etc. has emerged, and the display area and display quality for the characters, images, etc. are major factors in considering the performance of the wireless terminal device. Therefore, it is required to mount a display device as large as possible on a wireless terminal device having a limited size.

By the way, in a conventional telephone device, a push button, which is generally called a ten-key or a keypad, to which numbers and symbols are assigned is pressed to input the telephone number of the other party's telephone to be connected. Thus, the selection signal corresponding to this telephone number is transmitted to the switching device of the line network. However, keypads such as the ones above
Since it has 0 to 12 push buttons, it requires a large area, which is an obstacle to downsizing of the wireless terminal device and upsizing of the display device.

Therefore, for example, "Japanese Patent Laid-Open No. 4-24583"
Japanese Unexamined Patent Publication No. 7 ”discloses a telephone input device in which a keypad that occupies a large surface of the device is replaced with a so-called jog dial. This telephone input device has a rotating means that is rotated by a human finger and is displaced by being pressed. The amount of rotation of this rotating means is identified as a number and a symbol of a telephone number, and it is determined by the pressing time of the rotating means. , The input telephone number setting and the hook operation for on-hook or off-hook can be selectively operated.
Thus, by replacing the keypad having 10 to 12 keys for inputting numbers and symbols with one jog dial, the size of the telephone is reduced.

[0005]

However, in the above-mentioned telephone input device, only one rotating means is provided, and 10 numbers and 2 are provided in this one rotating means.
Since a total of 12 numbers and symbols are assigned to each symbol, the rotation angle per number and symbol is reduced. Therefore, when inputting numbers and symbols, there is a possibility that mistaken operation of inputting numbers and symbols assigned before and after the target numbers and symbols may occur. In addition, there was a problem in operability for prompt input. Therefore, the present invention has been made in view of the above circumstances, and an input device capable of significantly improving operability and reducing erroneous operations without impairing reduction in surface area and internal volume. It is an object of the present invention to provide a mobile phone device using the.

[0006]

In order to achieve the above object, an input device according to the present invention comprises a plurality of rotating means to which predetermined numbers and symbols are respectively assigned, and the amount of rotation of the rotating means is determined. The numbers and symbols are accordingly recognized, and the recognized numbers and symbols are input by pressing the rotating means. By thus assigning predetermined numbers and symbols to the plurality of rotating means, the number of numbers and symbols assigned to one rotating means may be small, and a large rotation angle can be secured for each number and symbol. be able to. For this reason,
When the rotating means is rotated to select the numbers and symbols, it is possible to easily select the target numbers and symbols.

Further, depending on the method of pressing the rotating means,
It is preferable to perform the input operation of the numbers and symbols or the switching operation between the off-hook and the on-hook of the telephone device. With this configuration, it is possible to input numbers and symbols and to switch between off-hook and on-hook only by operating the rotating means.

Further, it is preferable that a plurality of arrangement patterns are assigned to each of the rotating means, respectively, and that one arrangement pattern is selected and set in advance from the plurality of arrangement patterns. With this configuration, the user can select and set the array pattern according to his or her preference in advance.

Further, a display means for displaying the data is provided, and in the display area of the display means, the arrangement state of numbers and symbols assigned to each of the rotating means is arranged in an area close to the rotating means, and It is preferably configured to display the currently recognized numbers and symbols. With this configuration, the number / symbol selected by the rotating means can be clearly recognized.

As shown in FIG. 3, the portable telephone device 1 includes a functional circuit 21 such as a multiplexer, a transmission section 22 and a reception section 23 for processing such as frequency conversion, a modulation / demodulation processing section 24 for performing modulation and demodulation processing, A control / signal processing unit 25, for example, a microprocessor, which controls a control channel required for control in a wireless public network and a data channel for voice, data, etc., and performs signal processing such as encoding and decoding. Input control means 2 realized by (MPU) or the like
6, a memory 27 storing a control program for the entire apparatus, and a ringer (speaker) 28 for outputting a call signal of a switching network as a voice signal.

The input control means 26 controls each of the rollers 16a, 16b, 16c based on the arrangement mode (arrangement pattern) preset by the user using the numeral / symbol arrangement selection key 15a of the function selecting button group 15. Assign numbers and symbols. This arrangement mode has two arrangement modes of the ITU standard mode and the non-ITU standard mode in the present embodiment, and each time the number / symbol arrangement selection key is pressed, the ITU standard mode and the non-ITU standard mode are arranged. The mode switches. Further, the set array mode is displayed as “ITU” or “non-ITU” on the liquid crystal display device 14 as shown in FIGS. 4 and 5, for example.

In the ITU standard mode, each column of an array of numbers and symbols conforming to the 4 × 3 array of ITU (International Telecommunication Union) -T Recommendation E161, that is, "1," as shown in FIG.
4, 7, * "," 2, 5, 8, 0 ", and" 3, 6,
"9, #" are assigned to the rollers 16a, 16b, and 16c, respectively. On the other hand, in non-ITU standard mode,

Further, the input control means 26 has on / off signals S1a, S1 for the push button switches 18a, 18b, 18c.
1b, S1c, and encoder means 19a, 19b,
The detection signals S2a, S2b, S2c of 19c are input. The input control means 26 uses the on / off signal S1.
a, S1b, S1c, and detection signals S2a, S2b,
Based on S2c, transmission of a selection signal (input operation of numbers and symbols) and control of line capture and line release, that is, on-hook and on-hook control are performed.

That is, the input control means 26 discriminates the transmission operation of the selection signal or the hook switch operation of the on-hook / off-hook by the time length of the on / off signal S1 generated by pressing the three rollers 16. . here,
When the on / off signal S1 is less than a predetermined time (for example, 1 second), it is identified as the selection signal transmission operation. Then, the input control means 26 determines each roller 16 based on the array mode set as described above and the detection signal S2.
It is recognized that the numbers and symbols currently selected by a, 16b, and 16c have been input. On the other hand, when the on / off signal S1 is equal to or longer than the predetermined time (for example, 1 second), it is identified as the hook switch operation. Then, the input control means 26 performs an on-hook operation when the device is in an on-hook state and an on-hook operation when the device is in an off-hook state.

Below the display area of the liquid crystal display device 14,
For example, as shown in FIG. 8 or 9, each roller 16a, 1
At the positions corresponding to 6b and 16c, the key / numeral arrangement of the numbers and symbols of the arrangement mode set at that time is displayed. When the user rotates one of the rollers 16a, 16b, 16c with a finger, the input control means 26 causes the detection signals S2a, S2.
b, recognize the number / symbol selected based on S2c,
These numbers / symbols are displayed on the keyboard layout as so-called reverse characters with the brightness reversed. The numbers and symbols that have already been input are displayed in the telephone number display area A. Note that FIG. 8 shows a state in which the number “6” is selected by the roller 16c, and FIG. 9 shows a state in which the number “0” is selected by the roller 16c.

Next, the operation of the mobile phone device 1 having the above-described structure for transmission will be described. First,
In a so-called on-hook (line disconnected) state in which the mobile phone device 1 does not capture the line, the user sets the rollers 16a, 16
When either b or 16c is pressed for a predetermined time (for example, 1 second) or more to perform the hook switch operation, the input control means 26 recognizes that the switching operation from the on-hook to the off-hook has occurred. Then, the input control means 26 instructs the transmission of the calling signal, and the calling signal is transmitted to the base station of the wireless switching network via the control / signal processing unit 25, the modulation / demodulation processing unit 24, the transmission unit 22, and the antenna 11. It The wireless switching network which has received the calling signal is in a state of accepting the selection signal.

Next, the user rotates the roller 16 in accordance with the telephone number of the other party desired to be connected and stops at the position of the corresponding numeral / symbol, and the roller 16 is operated for transmitting the selection signal. Press for less than a predetermined time (for example, 1 second).
At this time, the input control means 26 recognizes that the selected numeral / symbol is input based on the on / off signal S1 and the detection signal S2. Then, the input control means 26 instructs the transmission of the selection signal, and the selection signal is transmitted to the base station of the wireless switching network as in the case of transmitting the calling signal.

For the second digit and after of the desired telephone number,
The same operation as above is repeated to transmit the selection signal. When the transmission of the selection signal is completed, the wireless switching network establishes a line connection to the terminal of the subscriber in the network based on the selection signal from the originating mobile telephone device 1 and transmits the paging signal. When the receiving terminal recognizes the ringing signal and seizes the line, End to
The link of End is formed and both parties can talk. When ending the conversation, the user presses any one of the rollers 16a, 16b, 16c for a predetermined time or more in order to perform a hook switch operation, and the input control means 26 performs a switching operation from off-hook to on-hook. Therefore, the procedure for disconnecting the line is performed to the wireless switching network. In the above description, the transmission of the selection signal to the wireless switching network is described as being executed every time when each digit of the telephone number is input, but after the input of all the digits of the necessary telephone number is completed, It is well known that there is also a method of capturing and transmitting all digit selection signals all at once.

Next, the operation for receiving will be described. A call signal transmitted from a base station within the area where the user is located is received by the antenna 11 and input to the control / signal processing unit 25 via the receiving unit 23 and the modulation / demodulation processing unit 24. The control / signal processing unit 25 processes the ringing signal and outputs the ringing sound from the ringer 28. When the user who knows the incoming call presses any one of the rollers 16a, 16b, 16c for a predetermined time or longer, the input control means 26 recognizes that the switching operation from on-hook to off-hook has occurred. Then, the input control means 26 instructs the connection with the wireless switching network (capture of the wireless line), and the end-to-end communication becomes possible. The conversation is ended by performing the same operation as in the case of transmission.

As described above, by assigning twelve numbers and symbols to the three rollers 16a, 16b, 16c, the operability can be remarkably improved without reducing the surface area and the internal volume. Also, roller 1
Since the selection signal transmission operation and the hook switch operation can be performed only by operating 6a, 16b, and 16c, it is not necessary to separately provide an off-hook / on-hook switching button.

In addition, the arrangement mode in which numbers and symbols are assigned to the rollers 16a, 16b, 16c, respectively, is set to ITU.
The operability can be improved because the user can select from two arrangement modes, the standard mode and the non-ITU standard mode, according to his or her preference. ITU
In the standard mode, the key arrangement is similar to that of a general telephone set, and a user who is accustomed to this key arrangement can easily perform an input operation. On the other hand, in non-ITU standard mode,
The arrangement is in the order of natural numbers, and the user can perform input operations without being restricted by the key arrangement of a general telephone.

Further, by displaying the number / symbol key arrangement, the selected number / symbol, and the inputted number / symbol on the liquid crystal display device 14, the user can clearly recognize the selected number / symbol. A series of repetitive operations at the time of inputting a telephone number, such as rotating and selecting the roller 16 and pressing the roller 16, are speeded up, which contributes to a reliable call operation. In addition, even if such a display is performed, the content to be displayed on the liquid crystal display device 14 is extremely small at the calling stage when the off-hook operation is performed to make a call, so that other displays are not sacrificed.

[0027]

As described above, according to the input device of the present invention, it is possible to assign numbers and symbols to a plurality of rotating means. This makes it possible to secure a large rotation angle for each number and symbol, so that the operability can be significantly improved without impairing the miniaturization of the surface area and the internal volume. In addition, it is possible to reduce an erroneous operation of inputting numbers and symbols that are mistakenly followed.
