Abstract

PURPOSE:To prevent the automatic capture of a line wire due to an careless key operation by invalidating the key operation which is performed while an inhibition mode is set. CONSTITUTION:When a speech key is pressed at a slave device 3, the pressing of the speech key is invalidated while the inhibition mode is set at the slave device 3, and the speech key data are transmitted to the master device 1 while the inhibition mode is not set, and a line wire L is captured. And also, when an incoming call from the line wire to the slave device 3 is obtained, a CPU 32 judges the presence or absence of the setting of the inhibition mode, drives a tone ringer 35 while the inhibition mode is set, allows a speaker 36 to output an incoming call sound, and releases the inhibition mode. Afterwards, the speech key is pressed in order to respond to the incoming call, the count of a timer is temporarily stopped, and the incoming call response is operated. Then, when the completion of a speech is detected, the CPU 32 resets the inhibition mode. When the timer which indicates the period of the inhibition mode is timed-up, the inhibition mode is released, and the timer is reset.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device provided with a call key for capturing an outside line such as an office line, and operating the call key to make a call to the outside line and respond to an incoming call.

[0002]

2. Description of the Related Art Conventionally, in this type of telephone device, when a call key is pressed to make an outside call, the DC loop of the outside line is closed and the outside line is captured, and when a dial operation is subsequently performed, a dial signal is captured. The call is sent to the outside line to call the other party, and the outside line call is made according to the response of the other party. Further, when an incoming call arrives at an outside line, an outside line ringing tone is sent from a speaker, and when the call key is pressed at this time, the outside line is captured and a response to the incoming call is made.

[0003]

In such a telephone device, for example, when the telephone call key is mistakenly pressed while cleaning the telephone device, the outside line is automatically captured, and the outside line is used thereafter. There was a problem that it was considered as medium, and as a result, it was not possible to receive an incoming call to the outside line.

[0004]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention sets a prohibition mode in which a key operation is disabled in a telephone device which responds to an outside line call and an incoming call by operating a key. It is provided with setting means for performing. Further, when an incoming call arrives while the prohibit mode is set, the prohibit mode is canceled and the subsequent key operation is made effective. Further, it is provided with a timer that is activated when the prohibition mode is set by the setting means, and means for canceling the prohibition mode when the timer times out.

[0005]

If the key operation is performed while the prohibit mode is set, the key operation is invalid, so that it is possible to prevent the outside line from being automatically captured by the careless key operation. Further, since the prohibit mode is automatically released when a call arrives, it is possible to respond to the call regardless of whether the prohibit mode is set. Also,
Since the prohibit mode is automatically canceled after a predetermined time, it is not necessary to cancel the prohibit mode when making an outside line call.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a telephone device according to the present invention. This device is a cordless telephone device composed of a master unit 1 and a slave unit 3 and a wireless line connecting the units. Here, the base unit 1 detects an incoming call to the outside line L via the diode bridge DB1, an incoming call detection circuit 11, a call circuit 12, a dial IC 13 for sending a dial signal to the outside line L, a CPU 14, and an outside line L when the outside line is held. Hold IC 15 that sends a hold tone, wireless transceiver 16 that performs wireless communication with handset 3, dial key 17, call key 1
8. IDROM 19 for storing ID code of base unit 1, tone ringer 20 for generating various ring tones, switches SW1 and SW for switching outside line communication between base unit 1 and handset 3
2 and a transistor Q for capturing an outside line.

The slave unit 3 has a wireless transmission / reception unit 31 for performing wireless communication with the master unit 1, a CPU 32, an IDROM 33 for storing an ID code of the slave unit, a key unit 34, a tone ringer 35 for generating various tones, and the like. It consists of The key unit 34 is provided with a call key for capturing an outside line, a dial key, an off key for ending a call, a hold key for holding an outside line, a prohibition key for invalidating the operation of the call key, and the like. ing.

When an incoming call arrives at the outside line L, the CPU 14 in the base unit 1 detects the incoming call through the incoming call detection circuit 11, and when the incoming call is determined to be the incoming call to the handset 3. Incoming call data is transmitted to the handset 3 via the wireless transmission / reception unit 16. When receiving the incoming call data via the wireless transmission / reception unit 31, the CPU 32 of the child device 3 drives the tone ringer 35 to send the outside line ringing tone from the speaker 36. When the call key is operated in the handset 3 receiving an outside line, the call key data is transmitted from the CPU 32 to the base unit 1, and the CPU 14 of the base unit 1 sends the call termination stop data to the handset 3 at this time. To stop the external line ringing tone, and turn on the transistor Q via the dial IC 13 to respond to the incoming call and to switch SW1, S
The contact point of W2 is switched to the wireless transmission / reception unit 16 side. In this way, a response call for an incoming call from an outside line is made in the handset 3.

When the call key is operated in the case of making an outside line call in the handset 3, the call key data is similarly transmitted to the base unit 1, and the CPU 14 of the base unit 1 which receives the call key data , The transistor Q is turned on via the dial IC 13, the DC loop of the external line L is closed, and the contacts of the switches SW1 and SW2 are switched to the wireless transmission / reception unit 16 side. As a result, the dial tone coming to the outside line L is heard in the handset 3, and when the dial key of the handset 3 is operated in this state, the dial key data is transmitted to the base unit 1. When the CPU 14 of the parent device 1 receives the dial key data, it sends a dial signal from the dial IC 13 to the outside line L to call the other party, and the outside line call of the child device 3 is performed according to the response of the other party. In this example,
When the prohibition key of the child device 3 is operated to enter the prohibition mode, various key operations subsequent thereto are invalidated.
Therefore, it is possible to prevent the outside line L from being automatically captured, for example, by accidentally touching the call key during cleaning of the child device 3.

Next, FIG. 2 is a flowchart showing the operation of the CPU 32 in the slave unit 3. The detailed operation of the present invention will be described based on this flowchart. When the call key is pressed in the handset 3 and it is determined to be “Y” in step 200, it is determined in step 201 whether the handset 3 is set to the prohibit mode, and if the prohibit mode is set. As described above, the pressing of the call key is invalidated (step 202). If it is not the prohibit mode, the call key data indicating the call request signal is transmitted to the base unit 1 to capture the outside line L.

If the prohibit key is pressed on the slave unit 3 and the answer is "Y" in step 204, then it is determined in step 205 whether or not the prohibit mode is set. If the prohibit mode is not set, After setting the prohibit mode (step 206) and starting a timer for a predetermined time (step 207), the prohibit mode is displayed on a display unit (not shown) (step 208). If the prohibit mode is already set, the prohibit mode is released (step 210) and the timer is reset (step 211).
Then, the prohibit mode display is turned off (step 2
12). If any other key than the above keys is pressed and it is determined to be "Y" in step 213, it is determined in step 214 whether or not the prohibit mode is set, and if the prohibit mode is set, the above is performed. As with the call key, the pressed key is invalidated (step 215), and if not in the prohibit mode, the other pressed keys are processed (step 216).

[0012] In addition, an external line incoming to the handset 3 or the base unit 1
There is an extension call to the handset 3 due to calling
If it is determined to be "Y" in step 20, it is determined in step 221 whether or not the prohibit mode is set. If the prohibit mode is set, the tone ringer 35 is driven to emit the ring tone from the speaker 36 ( Along with step 222), the prohibit mode is released (step 223). Thereafter, it is determined whether or not the call key for answering the incoming call is pressed (step 224). When the press of the call key is detected, the count of the timer is temporarily stopped (step 225) to allow the incoming call answering call. When the end of the call is detected and it is determined to be "Y" in step 226, the timer count is restarted (step 227), the prohibit mode is reset (step 228), and the process returns to step 200. If there is an incoming call when the prohibit mode is not set, the tone ringer 35 is driven and the ring tone is output to the speaker 26.
Is released (step 229) and the call key is detected (“Y” in step 230) to shift to a normal incoming call and the end of the call is detected (“Y” in step 231). Return to 200.

If the timer indicating the period of the prohibit mode has timed out and it is determined to be "Y" in step 240, the prohibit mode is released (step 241) and the timer is reset (step 242). Further, the prohibition mode display is turned off (step 243).

As described above, according to the present invention, the key operation is disabled while the prohibit mode is set, and the key operation for responding to an incoming call is enabled, and after the answering call is finished. The prohibit mode is set again. As a result, it is possible to prevent the outside line from being automatically captured when the key of the child device 3 is inadvertently pressed. In the present embodiment, as an example of invalidating the key operation during the prohibit mode setting, the cordless telephone device slave unit 3 is used.
However, the same effect can be obtained even when applied to a single telephone, a key telephone, or the like.

[0015]

As described above, according to the present invention,
Even if a key operation is performed while the prohibit mode is set, the key operation is invalid, so that there is an effect that it is possible to prevent the automatic capture of an outside line by an inadvertent key operation. In addition, since the prohibit mode is automatically released when a call arrives, it is possible to respond to an incoming call regardless of whether the prohibit mode is set or not, and the set prohibit mode is automatically released after a predetermined time. Therefore, it is possible to omit the trouble of canceling the prohibit mode when making an outside line.
