Description

The present invention relates to a telephone device in which a dial key is provided on the handset side.

[Prior Art] In recent years, the number of usable models of telephones has increased, and a user can freely select and use from telephones having various functions. Conventionally, when dialing, the user went off-hook and held the handset in his hand while dialing from the telephone body. However, the handset must be held even though it does not contribute to the dial operation, and it is unreasonable to operate the handset away from the handset. Due to such an idea, many devices are equipped with dial keys on the side of the handset.

[Problems to be Solved by the Invention] However, such a handset may erroneously touch a dial key during a call, and in this case, a dial signal is sent to the other party, which causes discomfort to the other party. Will be given.

[Means for Solving the Problem] In order to solve such a problem, the present invention provides a setting means for setting a dial operation to an invalid state or an effective state,
The setting operation is controlled so that the dial operation is disabled based on the transition to the call state with the specific key and the other party, and the dial operation is set to the valid state based on the operation of the specific key after the transition to the call state. It is provided with a control means.

Further, the control means controls the setting means to invalidate the dial operation based on the transition to the communication state with the other party, and to the state opposite to the state set by the setting means for each subsequent operation of the specific key. This is set.

Further, the control means controls the setting means based on the end of the call to enable the dial operation.

[Operation] The dial operation is disabled based on the transition to the call state with the other party, and the dial operation is set to the valid state by the operation of the specific key after the transition to the call state.

Further, after the dial operation is set to the invalid state, the cancellation of the invalid state and the setting of the invalid state are repeated for each operation of the specific key.

 Also, the dial operation becomes valid based on the end of the call.

[Embodiment] FIG. 1 is a block diagram of an apparatus to which the present invention is applied. M is a master unit, S is a slave unit, and the master unit and the slave unit are connected by a wireless line. In the base unit, 1 is an external line terminal, 2 is an incoming call detection circuit, 3 is a transistor for dial transmission,
Reference numeral 4 is a driver for driving the speaker 9, 5 is a CPU for controlling the whole, 6 is a 2-wire / 4-wire switching circuit, 7 is a wireless transmission / reception unit,
Reference numeral 8 is a PB signal transmitter, 9 and 10 are relays, 11 is an antenna, 21 is a call current supply circuit for supplying a call current to the telephone set T, 22 is a ringer, and 23 is a dial signal generator.

The handset S is a call key 32, a dial key 33, a speaker
Driver 34 for driving 39, CPU 35, indicator 36 for key lock status display, wireless transmitter / receiver 37, key lock switch 3
It is composed of 8, a call key 39, a handset 40, a cut key 42, and an antenna 41. The display 36 is lit when the key is locked, and turned off when the key is unlocked.

In this device, when an incoming call is received from an outside line, a slave unit is called, and by picking up the slave unit from a charger (not shown), a call with the other party can be performed.

At this time, the key lock process is performed when the child device is picked up, and the dial signal is not transmitted even if the dial key is touched by mistake.

FIG. 2 is a flow chart showing the operation of this device. In the figure, after initial settings are made in step 100,
When an incoming call to the outside line is detected in step 101 and a call state transition is detected in step 102, that is, when the handset S is picked up from a charger (not shown) or when it is detected that the call button is pressed, The key lock process shown in step 103 is performed. The key lock process is a process for locking the dial key by software so that the dial signal is not transmitted even when the dial is operated.

Although the dial keys are locked, the call state is entered in step 102, so that an outside line call is made in step 103. Normally, dial operation is not required during a call, but for transfer, for example, dial operation is required even during a call.

For such a case, the key lock switch 38 is provided in the child device, and when it is confirmed in step 105 that the switch has been pressed, it is determined in step 106 whether or not the key lock is being set.

If the key lock is being set, the key lock release process of step 107 is performed by operating the key lock switch. Then, steps 104, 105, and 108 are repeated until the end of call is determined in step 108. When the dial operation for transfer is completed, it is not necessary to generate the dial signal thereafter. Therefore, when the key lock switch is pressed again, this is determined in step 105. Since the dial lock was released for the transfer first, it is determined that the key lock is not set at step 106 at this point. Based on this determination, the key lock process is performed in step 109. That is, each time the key lock switch is pressed, the key lock state and the key lock release state are switched alternately.

Then, when the end of the call is detected in step 108,
In step 110, the key lock processing is released, and other processing shown in step 111 is performed. Step 1
The other processing in 11 is processing such as ringer driving for a call from the outside line.

If the call state is not entered in step 102, other external arrival processing shown in step 112 is performed. That is, the key lock state is released by the end of the call. Step
If it is not external arrival at 101, other processing shown in step 111 is performed.

Although the above explanation has been made with the cordless telephone device, it may be an ordinary telephone in which the main body and the handset are connected by a cord. The operation of all keys except the keys may be invalidated. Also, it is possible to disable all key operations except the key lock switch, but since it is necessary to operate the cut key at the end of the call, in this case the key lock status indicator will indicate whether the key is locked or not. Check and set the key lock release state before operating the cut key.

Further, the key lock process during the call after the call is the same as the key lock process at the time of the incoming call described above, and the key lock process during the extension call between the handset and the 2W telephone is also the same.

Further, the key lock process is performed when the call state is shifted, but it may be performed by detecting that the dial key is pressed.

[Effects of the Invention] As described above, according to the present invention, the dial operation is disabled based on the transition to the call state with the other party, and the dial operation is enabled based on the operation of the specific key after the transition to the call state. Since it is set to, the dial signal is not sent even if the dial key is accidentally touched during a call, so it has the effect of not causing discomfort to the other party. The dial operation can be validated by operating a specific key if necessary, so that there is an effect that a service using a dial signal, such as a fax information service, can be used.

In addition, the dial operation is disabled based on the transition to the call state with the other party, and the operation is set to the state opposite to the state set by the setting means for each subsequent operation of the specific key. This has the effect that the dial operation can be enabled / disabled at any time.

Further, since the dial operation is made effective based on the end of the call, there is an effect that the dial operation becomes effective immediately at the next off-hook.
