BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple mobile phone suitable for application to PHS and the like.

[0002]

2. Description of the Related Art Recently, a PHS (Personal Handy) that can be used outdoors as a mobile phone and indoors as a cordless slave unit by connecting to a master unit installed indoors can be used.
Simple mobile phones such as System) are attracting attention.

For this type of portable telephone, a model has been developed which is always equipped with an answering machine function, a speed-dial telephone function and the like, like the stationary telephone. Furthermore, LC is used for simple mobile phones.
A display device such as D is provided so that the telephone number of the call destination can be displayed here.

[0004]

By the way, even in such a simple type portable telephone, a ring tone sounds when there is an incoming call, and this ring tone continues to ring until an off-hook operation is performed. On the other hand, due to the mobility of the mobile phone, the mobile phone is often used in business meetings and business meetings while in a bag or a handbag. When there is an incoming call during a meeting or during a business meeting, a ring tone sounds, and this sound often hinders the progress of the meeting or the business meeting. In such a case, it is better to be able to mute the ringtone.

However, if the ring tone is simply muted, then the telephone holder may not notice that there is an incoming call at all. This does not take advantage of mobile phones.

When moving to such a specific place, the ring tone can be silenced in advance by the user's intention, and even in that case, it can be surely known who and where the call came from. The purpose can be sufficiently achieved without impairing the function of.

Therefore, the present invention solves such a conventional problem, and in particular, by skillfully utilizing the answering machine function, the ring tone can be muted according to the purpose, and the calling side can be muted. It proposes a simple mobile phone capable of specifying the.

[0008]

In order to solve the above problems, according to the present invention as set forth in claim 1, an answering machine mode capable of muting a ring tone is set, and when this answering machine mode is set. Send a response message to the calling side prompting the calling side to enter the designated key code for the message,
When the designated key code for a message is received from the calling side, this message is displayed on the display section of the called side.

[0009]

[Function] When an incoming call is received in a state where the answering machine capable of muting the ring tone (called mode B) is set, the ring tone is muted and at the same time, the response message B is transmitted to the calling side. . Upon receiving the response message B, the calling side inputs the corresponding designated key code (the relationship between the message and the code is registered in advance) to send the message to the called side.

The called side demodulates the designated key code, refers to the registration table, generates a corresponding message, and displays it on the display unit 37 (FIG. 4). Since the message includes the name of the calling side, it is possible to confirm who the call came from by the content of the message on the display unit 37. Since the calling party can be specified by the message, the calling party can be contacted after confirming the message. In this way, even if there is an incoming call during a meeting or during a business meeting, the meeting or business meeting is not hindered, and the display unit 3 is occasionally displayed.
Whether or not there is an incoming call can be determined simply by checking 7.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a case where an example of a portable telephone according to the present invention is applied to the above-mentioned PHS will be described in detail with reference to the drawings.

For convenience of explanation, description will be made with reference to FIG. FIG. 4 is a system diagram showing an example of the PHS type telephone 10 to which the present invention is applied. The transceiver 12 includes a transmitter 12a and a receiver 12.
b. The voice signal from the transmitter 12a is transmitted to the wireless unit 14
In (1), the signal is transmitted to the base station from the antenna 16 after being formed into a predetermined signal form. The incoming signal received by the antenna 16 is demodulated by the wireless section 14 and then converted into a voice signal and supplied to the handset 12b.

When connecting the line, the telephone number of the other party is input through the operation unit 18, and this is input through the control unit 20 composed of a microcomputer to the DTMF (Dual Tone Multiple Frequency).
cy) is supplied to the modulation / demodulation unit 22 and a two-frequency dial signal is generated. The two-frequency dial signal is supplied to the wireless unit 14.

The voice recording / reproducing unit 26 is for recording an incoming message in the absence recording mode, and a voice memory or the like is used. Therefore, the audio output obtained from the wireless section 14 is supplied to the audio recording / reproducing unit 26 and recorded (memory). Since the message reproduced by the voice recording / reproducing unit 26 is supplied to the handset 12b via the switch 30, its content can be confirmed.

The voice synthesis unit 32 stores voice data for generating a response message (fixed sentence or original sentence, details of which will be described later) when operating as a called side. At this time, the voice data is supplied to the wireless unit 14 via the switch 34, so that the content is transmitted to the calling side. The switches 36a and 36b provided on the transmitter / receiver 12 side are switches used to mute the incoming call tone, and in principle, only the switch 36b is required.

On the display unit 37, numbers and katakana such as telephone numbers and messages of the other party are displayed. The control unit 20 including a microcomputer has a memory 38 such as an EEPROM.
In the memory 38, the relationship between a designated key code on the calling side and a message consisting of numbers and katakana corresponding to it as shown in FIG. 6 is tabulated and stored. Therefore, the control unit 20 has a function of converting the designated key code into a message corresponding to the designated key code.

The plurality of switches 30, 34, 36 described above
Both a and 36b are controlled by a control signal corresponding to the operation mode obtained from the control unit 20.

FIG. 5 is a schematic view of the simple type portable telephone 10, in which the receiver 12b is located above the device body 40, the transmitter 12a is located below the device main body 40, and the display section 37 is provided in the upper center thereof. . A display element such as an LCD can be used as the display unit 37. In this example, in the two-stage configuration, the upper display element 37a displays the menu content, and the lower display element 37b displays the response content to the menu content. Is displayed. The response contents are displayed in the left and right areas 46 and 48, respectively.

A function key 4 is provided at the center of the apparatus body.
2 and numeric keys 44 are provided on the lower side thereof. In the function key 42, 50 and 52 are left and right shift keys, and 54 and 56 are up and down shift keys. Reference numeral 58 denotes a function key, which is used for menu selection and selection of various functions (speed dial function, answering machine function, etc.) built in the apparatus. Reference numeral 60 denotes a registration key, which is used for confirming input data. In the numeric keypad 44, 62 and 64 are special input keys.

In the PHS telephone 10 according to the present invention having the above-described structure, in addition to the usual answering machine (absent answering mode A), which is commonly known as an answering machine, the answering machine can mute the ring tone. Recording mode (absent recording mode B) is prepared. When the message recording mode B is selected, the contents of the message are slightly different between the modes A and B because the caller needs to input the message with the designated key code.

For example, the response message A sent to the calling side in the answering machine mode A is a fixed message such as the response message A ... "Please give your name and requirement for the visitor now." .

On the other hand, in the answering machine mode B, the content is such as the response message B ... "Please enter your name and requirement with a code while visiting". This is because the message is not recorded when the message recording mode B is selected.
This is for displaying the caller's message (including the telephone number) on the display 7.

The relationship between the designated key code and the message will be described with reference to FIG. For example, the special key 62 and the following four-digit number are arranged to display the name of the calling party. As shown in FIG. 6, for example, when the code is “# 1234”, the name “Adachi” is designated, and “adachi” is displayed in katakana on the display unit 37 by this designation code. Another name can be specified using another four digit number.

When an 8-digit or 6-digit number is input after the 4-digit number, it represents the telephone number of the calling party. Therefore, for example, "# 12343429
When the designated code "16251" is input, it is displayed as "Adachi 32916251". This tells that the caller is "Adachi" and the telephone number is "3291-6251".

Similarly, a special message is represented by a special key 64 and a two-digit number. In this example, “* 12” represents the message “Denwakyu”.
Therefore, the input designation key code is "* 12329162
When it is 51 ”,“ Denwa Shikyu 32916
251 ”is displayed. Another two-digit number can be used to display another message. Therefore, the relationship as shown in FIG. 6 is tabulated and registered in the memory 38 in advance. The recorded message mode B functions only when the relationship in the registration table is observed.

FIG. 2 shows an example of the function selection menu.
When the message recording mode A is selected, this mode is set and the message A for the message recording mode A described above is set (steps 71, 72, 73). On the other hand, when the message recording mode B is selected, this mode is set and the message B for the message recording mode B described above is set (steps 75, 76, 7).
7).

When the answering machine mode B is set, the control unit 20 shown in FIG. 4 operates to control the switches 36a and 36b to the open state, and a message is displayed in the procedure shown in FIG.

First, when an incoming call is received, the switch 36b provided on the side of the handset 12b is in the off state, so that no ringing tone sounds. That is, the sound is muted (step 81,
82). After the call is received, the called side sends a response message B to the calling side, and the calling party inputs the designated key code by this message B (steps 83 and 84).

When the designated key code is input, the key data is demodulated by the DTMF modulator / demodulator 22 and then supplied to the controller 20, so that the demodulated key data is stored in the memory 38 (step 85, 86). After that, the demodulation key data and the data in the table in the memory 38 are referred to, and the corresponding numerical data and character data are read,
This is supplied to the display unit 37 and the message is displayed for a predetermined time (step 87). When the line is disconnected, this display processing operation ends (step 88).

The called party does not always look at the display contents immediately after receiving a call, and the probability of not seeing the displayed content is higher. Therefore, the redisplay mode is necessary. FIG. 3 shows an example of the redisplay processing routine. For example, a specific function key 4
Assuming that the display key is represented by a combination of 2 and a specific ten key 44, the demodulation key data is read by operating this display key, and the corresponding message is generated and supplied to the display unit 37 ( Steps 91, 92). The display state is continued until the display time t exceeds the prescribed time Ta, and when the predetermined time Ta has passed, the message is turned off and the demodulation key data is erased (steps 93, 94, 95).

The predetermined time Ta is a time sufficient for confirming the contents of the message and making a memo of the contents of the message if necessary, and is set to about 10 to 20 seconds. Since this demodulation key data becomes unnecessary after displaying the message, it is deleted so that the memory 38 can be effectively used.

FIG. 7 is a specific example showing the procedure for registering the designated code, in which the name is registered first. In the first menu screen, a display as shown in A of the figure is made, and when the left shift key 50 is operated, a four-digit number input mode is entered (B of the same figure), and the ten-key 44 is used to input the four-digit number and the registration key 60
When is operated, the number is confirmed (C in the same figure).

Next, the mode shifts to the name input mode (D in the figure), and when the corresponding katakana is also input using the ten keys 44 and the registration key 60 is pressed, the input name is confirmed (E in the figure). . When the name is confirmed, the next mode is the message input mode. In this case, the right shift key 52 is operated to shift to the message input mode (F in the figure). A message is entered using the numeric keypad, and the registration key 60
The contents are determined by (G in the same figure).

By this series of processing, the registration of the designated key code and the message corresponding thereto is completed. When multiple callers are considered to be received by voice mail mode B,
The above registration process is performed for each caller.

FIG. 8 shows an example of actual display contents displayed on the display unit 37. First, there is a confirmation mode for the set of the answering machine mode B (this is displayed as "Journal Out B" in the figure), and the left shift key 50 indicates confirmation.
Answering mode B is set by operating (A in the figure). When there is an incoming call in this mode B, the incoming call status is displayed as shown in FIG. At this time, the ring tone does not sound.

Next, when the caller inputs the designated key code, the caller's name is displayed as shown in FIG. 6C through the display state of FIG. 7C, and further, the designated key code is further input. Then, for example, a message as shown in FIG. The line is disconnected in this state, but when the line is disconnected, the number of incoming calls is incremented to "1" as shown in FIG. When the confirmation mode is further selected in this state, since the number of incoming calls is "1" in this example, a fixed message such as "Arimasen" is displayed on the display unit 37 as shown in FIG. When the down shift key 56 is pressed, the display state shown in FIG.

Although the above-described embodiment applies the present invention to the PHS type telephone, it can also be applied to other simple type portable telephones.

[0038]

As described above, in the simple type portable telephone according to the present invention, a new mode is provided as an answering machine mode in which the ring tone can be muted, and a corresponding message is input by the designated key code input from the calling party side. It can be displayed on the display unit.

According to this, the ringing tone does not interfere with the signal of the meeting or the business talk, and in that case, the display unit can confirm the incoming call from anyone, so that it can be promptly issued. It has features such as being able to contact the caller. Therefore, the present invention is suitable for application to a simplified mobile phone such as a PHS phone as described above.
