Related to the device .

[0002]

2. Description of the Related Art Conventionally, telephone number input devices for telephones include a well-known rotary dial type or a push button type called a push phone. As is well known, the rotary dial type has a rotary disk in which holes corresponding to numbers from 0 to 9 are continuously arranged in an arc shape, and a person's finger is hung on the holes to rotate. As a selection signal after calling, the number of pulses corresponding to the amount of rotation of the rotating disk, that is, a number, is transmitted to the exchange via the central office line. In the push button type, push buttons for numbers from 0 to 9 and other symbols are arranged on the exterior of the telephone, and a dual tone signal by pressing the push button corresponding to the telephone number is sent to the exchange through the office line. Sending out.

[0003]

However, the above rotary dial type requires a hole having a diameter into which a human finger is inserted, so that the diameter of the rotary disk becomes large and the apparatus becomes large. In addition, there is often no lighting provided, which makes operation difficult when used in a dark place. Even with the push button type, a button of a required area is required to easily perform a telephone number input operation with a human finger, and a relatively large area for separately arranging the buttons is required. Would. Furthermore, in order to use it in a dark place, a lighting mechanism is necessary to illuminate all the push buttons,
There is a disadvantage that the configuration is complicated.

Further, when a push button is provided inside the above-mentioned push button type handset, there is a drawback in use that the push button comes into contact with a human face during a call and the push button is easily pressed inadvertently. In particular, a mobile telephone using a recent public line often has a problem in that a telephone call is made during walking. Furthermore, when the mobile phone is used in a dark place, illuminating all of the push buttons increases the battery consumption and cannot respond to recent long-term calls.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been made compact and easy to operate based on a simple structure, and has a simplified lighting mechanism to save power. It is an object of the present invention to provide an excellent telephone device and communication terminal device that can achieve the above.

Further, below the roller 20, when the roller 20 is pressed in the direction of the arrow M as described above, a selection signal after the call described later, that is, setting of the input telephone number, on-hook, And a setting switch unit 40 for performing an off-hook switching operation. The setting switch section 40 has a contact plate 42 that comes into contact with the roller 20. The contact plate 42 moves up and down, and the tact switch 44 is switched by moving the shaft 42 a up and down. By this switching, the tact switch 44 outputs the on / off signal Sb.

FIG. 3 shows a signal processing section when this configuration is a wired telephone. This signal processing unit is connected to a line interface (I / F) 50 via a local line (so-called L ₁ , L ₂ ).
Is connected. The line I / F 50 performs a well-known switching between on-hook and off-hook, and forms and attenuates a DC loop with the exchange. An incoming call detector 52 is connected to this line I / F 50,
A ringing tone (ring tone) is transmitted from the speaker 54 connected here. This functions as a so-called conventional ringer (densin). Further, a speech network 56 is connected to the line I / F 50, and the speech network 56 processes a signal to the speaker 12 and a signal from the microphone 13 when making a call. For example, level adjustment, sidetone adjustment, and the like. Further, a CPU 60 for controlling the apparatus is provided. The CPU 60 transmits a telephone number, and switches on-hook and off-hook based on the detection signal Sa from the rotary encoder 30 and the on / off signal Sb from the setting switch unit 40. The switching control is performed. The CPU 60 has a detection signal S
a is inputted and the rotation amount of the roller 20, that is, the rotation amount detection unit 62 that outputs a signal corresponding to the number of the telephone number
Is connected. When the rotation amount is detected as a number of a telephone number, a known detection method of adding the rotation amount may be used. At the same time, a detection signal Sa is supplied to detect a rotation direction of the roller 20.
Is connected. The rotation direction detection unit 64, for example, connects the light emitting element and the light receiving element of the rotary encoder 30 to 9
It is arranged so as to have a phase difference of 0 degree, and in this case, the detection signal S
It may be determined whether or not a is input from either a sine wave or a cosine wave. Here, when the roller 20 is rotated to the right, the telephone number is [1-2-3-4-
5-6-7-8-9-0-#-*], and [*-#-0-9-8-7-6-5-5-3-2 in the case of left rotation.
-1], the rotation direction detection unit 64 first identifies right rotation or left rotation, and then the rotation amount detection unit 62
In the case of clockwise rotation, a signal counted as [2-3-4-5-6-7-8-9-0-#-*] is sequentially sent to the CPU 60 with the position before rotation as [1]. In the case of left rotation, the position before rotation is set as [*] and [# -0-9-
8-7-6-5-4--3-2-1] is sent to the CPU 60. Further, the CPU 60 is connected to an on / off detection unit 66 for performing on-hook and off-hook switching control. From the ON / OFF detection unit 66, for example, the roller 20 is depressed in the direction of the arrow M within one second to turn the tact switch 44 ON according to the ON signal time of the ON / OFF signal Sb input. The CPU 60 sends a signal to the CPU 60 that detects the number displayed on the LCD 18 at this time as the number of the telephone number.
In addition, the on / off detection unit 66 uses the on / off signal Sb when the roller 20 is depressed for one second or more to output a signal to switch off hook when on hook and to switch to on hook when off hook.
Send to 0.

The operation of the above configuration will be described. First, the operation in the case of reception will be described. A call signal from the exchange via a line is input to the line I / F 50, and the incoming call is detected by the incoming call detecting section 52, and a ringing tone is transmitted from a speaker 54 connected thereto.
With this call, the user of the telephone device
Is pressed in the direction of arrow M for one second or more to turn on the tact switch 44. Thus, the switching control is performed by the CPU 60 from the on-hook state to the off-hook state. As a result, a response signal is sent out, the line is connected to the called party through the exchange, and a call is made possible. The speaker 12 and the microphone 1 connected to the speech network 56 through the line I / F 50
Make a call using 3. At the end of the call, the roller 20 is pressed down in the direction of arrow M for one second or more. Thus, the switching control is performed by the CPU 60 from the off-hook state to the on-hook state. That is, an end signal is transmitted. These operating states, that is, the off-hook and on-hook states are displayed on the LCD 18 so that the user can easily confirm them.

Next, the operation in the case of transmission will be described. The user of the telephone device moves the roller 20 in the direction of arrow M shown in FIG.
Hold down for more than a second. Thereby, the switching control is performed by the CPU 60 from the on-hook state to the off-hook state. A so-called call signal is transmitted to establish a line connection.
Thereafter, the user rotates the roller 20 to cause the LCD 18 to display the first number of the desired telephone number. Then, press the tact switch 4 in the direction of arrow M within one second.
4 is turned on, and the number displayed on the LCD 18 is set as the first number of the telephone number through the CPU 60 to the line I.
/ F50. Then, the signal is transmitted to the exchange as a selection signal through the central office line connected thereto. By performing the same operation according to the digit string of the desired telephone number,
After the transmission of the selection signal is completed, connection with the other party is performed by the exchange. Also in this case, a call is made using the speaker 12 and the microphone 13 connected to the speech network 56 via the line I / F 50 as in the reception. At the end of the call, the roller 20 is pressed down in the direction of arrow M for one second or more. As a result, the switching control is performed by the CPU 60 from the off-hook state to the on-hook state, and a disconnection signal is sent from the line I / F 50 to the exchange via the office line. In this case, as in the off-hook and on-hook states, the numbers and the like are displayed on the LCD 18, so that the user can easily confirm the telephone number.

FIG. 4 shows the configuration of another signal processing section in the embodiment. This signal processing unit is for a digital telephone. In this example, a digital wireless public line is used, and a duplexer (not shown) for common use for transmission and reception is connected to the whip antenna 70, and
A reception unit 72 that performs processing such as amplification and frequency conversion of a reception signal at a predetermined frequency, and a transmission unit 74 that performs frequency conversion and power amplification are connected. A well-known modem 76 for performing modulation and demodulation processing is connected to the reception section 72 and the transmission section 74. Further, a B and D channel for performing decoding and encoding of a format B channel and a D channel in a digital wireless public line is connected. The channel processing unit 78 and the D channel processing unit 79 are connected. The speaker 12 and the microphone 13 are connected to the B channel processing unit 78. D channel processing unit 79
Is connected to a CPU 61 that controls the apparatus. A speaker 75 is connected to the CPU 61, and a call or the like at the time of an incoming call is performed by the speaker 75. The other configuration is the same as the configuration shown in FIG. 3, and the operation of this portion is also the same.

FIG. 5 shows another external configuration of the apparatus of the present invention. This is an example of a portable telephone which is particularly downsized compared to the telephone shown in FIG. In this mobile phone, a whip antenna 81 is provided on an exterior body 80. Further, an LCD 82 and a microphone 84 are provided.
An earphone 86 is connected instead of the speaker.
An input unit 88 for inputting a telephone number, off-hook, and on-hook is provided on the side of the exterior body 80. The input unit 88 has the same configuration as that described with reference to FIG. The internal signal processing section and the like are the same as those of the digital telephone described with reference to FIG. In the configuration in which the input unit 88 is arranged as described above, the size and weight are further reduced, and the convenience as a mobile phone is improved.

In the above embodiment, the numbers and symbols of telephone numbers are displayed on the LCD 18, but the present invention is not limited to this, and the numbers and symbols of telephone numbers may be displayed on the surface of the roller 20 itself. That is, the telephone number [1
-2--3--4-5-6-7-8-9-0-#-*],
At each position, a switching contact for fixing the roller 20 semi-fixed is provided, and a signal identifying the corresponding numeral is transmitted to the CPU 60 (61) through this contact. The numbers at the semi-fixed positions may be displayed on the LCD 18 at the same time. Also in this case, when the surface of the roller 20 itself is illuminated, the input operation of the telephone number in a dark place becomes easy. When not displayed on the LCD 18, the LCD 18 and the like become unnecessary, but since the area of the display portion is small, it is naturally smaller than the number displayed on the LCD 18. In this case, it is preferable to provide a lens cover on the roller 20 to enlarge the displayed number.

In the above embodiment, the optical rotary encoder 30 is used for inputting a telephone number or the like. However, the present invention is not limited to this. For example, a configuration using a magnetic rotary encoder may be used. Further, a ball is arranged in place of the roller 20, and the rotation in all directions is detected.
A so-called track ball XY coordinate input device can be used to process the output signal as described above to obtain a similar effect.

As described above, the configuration is simplified and the size of the conventional dial or push-tone telephone input device is reduced. Further, the input operation of the telephone number and the like becomes easy. In addition, since only the displayed numbers or symbols are illuminated, for example, the illuminated portion is narrower than that of the conventional dial type or push-tone type, the illuminating mechanism is simplified, and power saving is achieved. Will be done.
