Description

Telephone equipment

The present invention relates to a telephone device, and more particularly, in a telephone device having a large number of operation keys, when a certain key is pressed, the key operation of a numeric key is invalidated and the telephone device can be operated even if the key is accidentally pressed. Is designed not to malfunction.

  Current telephone devices have an increasing number of keys, such as abbreviated keys. For this reason, when cleaning between the keys, there is a possibility that the key may be accidentally pressed to cause a malfunction, which is very difficult to clean.

  As described above, the current telephone device has a large number of keys such as abbreviated keys. Therefore, there is a problem that a key is erroneously pressed during the cleaning of the telephone device to cause a malfunction.

According to the first aspect of the present invention, there are provided a plurality of numeric keys, an invalid portion for invalidating the key operation by the numeric key according to a user operation, and a key operation when the key operation by the numeric key is invalidated. A notification unit for notifying that the operation is in an invalid state, and the key of the numeric key until an operation for a call is performed even if an incoming call is detected in a state where the key operation by the numeric key is disabled It is characterized by maintaining an invalid operation state.
According to a second aspect of the present invention, in the telephone device according to the first aspect, the notification of the invalid state by the notification unit is by display .

According to the present invention, a plurality of operation keys such as numeric keys are provided, and by pressing a specific key among them, the key operation of the numeric keys of the key operation unit is invalidated. The function can be freely stopped when it is desired to temporarily stop the function. For example, by pressing this specific key during cleaning, the telephone device can be easily cleaned without causing the telephone device to malfunction.

In addition, when the incoming call is received when the numeric key of the key operation unit is in an invalid state, the structure in which the key is released by pressing the key may not be able to be operated accurately for a sudden event. Even if there is an incoming call when is pressed, the operation key is disabled until there is an operation for a call such as picking up the handset. Since the function is canceled, it can be operated as usual even when there is an incoming call.
Therefore, since the key operation of the numeric keys is invalid until an operation for a call is performed, the telephone device does not malfunction.

  FIG. 1 is a block diagram showing the configuration of a main part for explaining an embodiment of a telephone device according to the present invention. In the figure, 1 is a control unit for controlling the operation of the entire telephone device, and 2 is a specific key “P When the key 2 is pressed, the operation of all keys is invalidated or validated. The display unit (LED) 4 is lit when all keys are invalid and is off when valid. is doing. Reference numeral 3 denotes a key operation unit such as a numeric key or an abbreviated key, and reference numeral 8 denotes an incoming call detection unit that detects whether an incoming call has arrived, and is connected to the receiver 5 through the circuit interface 7 and the call circuit 6.

FIG. 2 is a flowchart for explaining the operation of one embodiment of the telephone device according to the present invention. When the above-mentioned specific key “P” is pressed (S1), the LED 4 is turned on (S2), and the key operation unit 3 is operated. All key operations are disabled (S3). In this state, the telephone device is cleaned (S4). After the cleaning is completed, when the specific key “P” is pressed again (S5), the LED 4 is turned off (S6), and all key operations are enabled (S4). S7), returning to the normal state (S8). In this way, all key operations of the key operation unit 3 can be invalidated / validated by pressing a specific key “P”.

  FIG. 3 is a flowchart for explaining processing when the specific key “P” is not pressed in S5 of the flowchart of FIG. In this case, all key operations of the key operation unit 3 are in an invalid state (S11), and the LED 4 is lit (S12). If the specific key “P” is pressed in this state (S13), the process returns to step S6 in FIG. 2 to turn off the LED and return to the normal state. When the time elapses (S14), the LED is turned off (S15), all key operations are enabled (S16), and the normal state is restored. When the specific key “P” is not pressed after the work, it has a function of automatically canceling the operation of the pressed specific key after a certain period of time and is controlled within the control unit 1 for a certain period of time. After that, even if the specific key “P” is not pressed, the operation of the specific key “P” first pressed automatically is released, and the normal state is restored.

  As a result, forgetting to cancel the state where key operation is disabled and considering that it may be mistaken for failure, the key operation is enabled after a predetermined time, so the key operation is disabled for a long time. Can be prevented.

  In FIG. 2, when the specific key “P” is pressed, it is displayed that the specific key “P” is pressed and all key operations of the key operation unit 3 are invalidated. In the flowchart shown in FIG. 2, when the specific key “P” is pressed (S1), the LED is lit (S2), indicating that all key operations of the key operation unit 3 are invalid. To do.

  Accordingly, in view of the fact that the user may not be aware that the key operation is in an invalid state, a display unit is provided to display that the specific key is pressed when the specific key is pressed. Therefore, it can be seen that this function is in operation by looking at the display section such as lighting of the LED or the like.

  FIG. 4 is a flowchart for explaining processing when there is an incoming call when the specific key “P” is pressed. By pressing the specific key “P”, the key operation unit 3 When all keys are in an invalid state (S21), and the LED is lit (S22), and an incoming call is received (S23), the incoming call detection unit 8 catches the incoming call, and the handset is When it is taken (S24), the LED is turned off (S25), all key operations are enabled (S26), and the normal state is obtained (S27).

  In other words, even if there is an incoming call when a specific key is pressed, the operation key is disabled until there is an operation for a call such as picking up the handset. Since the function of a specific key is canceled, it can be operated as usual even when there is an incoming call. Further, since all key operations are invalid until an operation for a call is performed, the telephone device does not malfunction.

  Alternatively, when a specific key “P” is pressed without taking the handset in S24 (S31), the LED is turned off (S32), all key operations are enabled (S33), and the normal state is obtained (S34). That is, by operating the specific key “P”, the operation of the specific key is returned to the valid state, and in this state, the handset is picked up (S35) and a call is performed.

It is a block diagram which shows the principal part structure for demonstrating one Example of the telephone apparatus by this invention. The operation of an embodiment of a telephone apparatus according to the present invention is a flow diagram of a theory Aquiraz order. FIG. 3 is a flowchart for explaining processing when a specific key “P” is not pressed in S5 of the flowchart of FIG. 2; It is a flowchart for demonstrating a process when there exists an incoming call in the state in which the specific key "P" was pushed.
