Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem such as erroneous operation due to erroneously pushing of keys during cleaning of a telephone device. <P>SOLUTION: Pushing a specific key "P" disables all keys on a key operating section (S21). When an incoming call arrives (S23) during the on state of an LED (S22), an incoming call detection section 8 catches the incoming call like a conventional telephone device. Then, when a telephone receiver is picked up (S24), the LED goes out (S25), and all the keys are enabled (S26) and put in a normal status (S27). Thus, the operation keys are disabled until operations for the purpose of a call such as picking up the telephone receiver are performed. Under this condition, a calling operation releases the specific key function, Accordingly, even the presence of an incoming call the user can perform the usual operation. Since the operations of all the keys are disabled until a speech operation is conducted, the malfunction of the telephone device can be avoided. <P>COPYRIGHT: (C)2004,JPO

Description

The present invention relates to a telephone device, and more particularly, to a telephone device having a large number of operation keys, when a certain key is pressed, all key operations are invalidated, and even if a key is erroneously pressed, the telephone device can be operated. This is to prevent malfunction.

The number of keys, such as abbreviated keys, is increasing in current telephone devices. For this reason, there is a possibility that a key may be accidentally pressed and a malfunction may occur when cleaning between the keys, and it is very difficult to clean the keys.

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

The invention according to claim 1 has a plurality of operation keys, and when a specific key is pressed, all the key operations are invalidated.

According to the present invention, a plurality of operation keys such as numeric keys are provided, and by pressing a specific key among them, all key operations of the key operation unit are invalidated. Can be freely stopped when it is desired to temporarily stop the telephone device. 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, in a structure in which a key is released by pressing a key when an incoming call is received while all keys of the key operation unit are in an invalid state, in view of the fact that it may not be possible to accurately operate for a sudden event, the specific key is Even if there is an incoming call when it is pressed, the operation keys are disabled until there is an operation for a call such as picking up the handset. Since the function is released, even when there is an incoming call, it can be operated as usual.
Therefore, since all key operations are invalid until an operation for a call is performed, the telephone device does not malfunction.

FIG. 1 is a block diagram showing a main part of a telephone device according to an embodiment of the present invention. In the drawing, reference numeral 1 denotes a control unit for controlling the operation of the entire telephone device, and 2 denotes a specific key "P". By pressing this key 2, all key operations are disabled or enabled, and the display unit (LED) 4 is turned on when all keys are disabled and turned off when enabled. are doing. Numeral 3 denotes a key operation unit such as a numeric key or abbreviated key, and 8 denotes an incoming call detecting unit for detecting whether an incoming call has arrived, and is connected to the receiver 5 through a circuit interface 7 and a communication circuit 6.

FIG. 2 is a flowchart for explaining the present invention. When the specific key "P" is pressed (S1), the LED 4 is turned on (S2), and all key operations of the key operation unit 3 are invalidated. (S3). In this state, the telephone device is cleaned (S4), and after the cleaning is completed, when the above-described specific key "P" is pressed again (S5), the LED 4 is turned off (S6), and all key operations become valid ( (S7), return to the normal state (S8). As described above, by pressing the specific key “P”, all key operations of the key operation unit 3 can be invalidated / validated.

FIG. 3 is a flowchart for explaining the processing when a 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). When the specific key "P" is pressed in this state (S13), the process returns to step S6 in FIG. 2, the LED turns off, and the display returns to the normal state. After the time elapses (S14), the LED is turned off (S15), all key operations become valid (S16), and the operation returns to the normal state. When the specific key “P” is not pressed after the operation, the function of the pressed specific key is automatically canceled after a predetermined time, and the function is controlled by the control unit 1 for a predetermined time. After a while, even if the specific key "P" is not pressed, the operation of the specific key "P" pressed first is automatically canceled and the operation returns to the normal state.

As a result, in order to forget to cancel the state in which the key operation is disabled, the key operation is made effective after a predetermined time elapses in consideration of the fact that it may be mistaken for a failure, 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 the 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 turned on (S2), indicating that all the key operations of the key operation unit 3 are invalid. I do.

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

FIG. 4 is a flowchart for explaining a process when an incoming call is received when the specific key “P” is pressed. When the specific key “P” is pressed, the key operation unit 3 is activated. When all the keys are in the invalid state (S21) and the LED is lit (S22) and there is an incoming call (S23), the incoming call detection unit 8 catches the incoming call and wakes up the handset as in a normal telephone device. When the key is removed (S24), the LED goes out (S25), all key operations are enabled (S26), and the normal state is set (S27).

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

Alternatively, when the specific key "P" is pressed without picking up the handset in S24 (S31), the LED turns off (S32), all the key operations are enabled (S33), and a normal state is set (S34). In other words, by operating the specific key "P", the operation of the specific key is returned to the valid state, the receiver is picked up in this state (S35), and the telephone conversation is performed.

FIG. 2 is a main block diagram for explaining an embodiment of the telephone device according to the present invention. It is a flowchart for demonstrating operation | movement of this invention. FIG. 4 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 the process when there is an incoming call when the specific key "P" is pressed.
