Abstract

PURPOSE:To be capable of invalidating the normal operation of a slave set. CONSTITUTION:In this cordless telephone set provided with not less than one slave set connected to a master set by radio, the slave set is provided with an operation part 1, an action part, a display part 3 displaying the operation state of the operation part and the acting part of the operation part, and a control part 2 controlling them. Furthermore, the cordless telephone set is provided, inside the slave set, with a storage part 5 for storing normal operation invalidity instructing information for invalidating the normal operation of the slave set. Consequently, without making prescribed operation, the invalidated slave set can not be turned back into the state of capable of normal operation, so as to prevent inconvenient action caused by mischief, etc., by a child. On the other hand, a part storing the valid and invalid state of normal operation is provided inside the slave set so that transmitting information to the action part of the slave set is unnecessitated so as to attain the locking of valid normal operation.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for restricting the use of a telephone, and more particularly to a cordless telephone with an operation lock function that can invalidate normal operation of a handset.

2. Description of the Related Art Among conventional cordless telephones, it has been known that the normal operation of a handset can be disabled by restricting outgoing calls and incoming calls. When the conventional transmission control is performed, the dial operation of the child device is invalidated. However, in this system, the telephone line is captured when making a call by simply disabling the dialing operation, so the telephone line is meaninglessly captured by a mischievous operation of a child, and the telephone line is busy during that period. In addition, there is also a problem that the remaining charge level decreases. In addition, in the incoming call regulation, although the audible ring tone is regulated or the visual display is stopped, it is possible to answer the incoming call by pressing the answer button. There was a chance

DISCLOSURE OF THE INVENTION The present invention does not simply limit the outgoing call or incoming call of a child device as in the conventional cordless telephone, but also makes the telephone line meaningless even by a mischievous operation of a child. There is no capture, so the telephone line is not inadvertently busy.
At the same time, the present invention aims to provide a cordless telephone in which the charge remaining amount does not decrease and the response to an erroneous incoming call does not occur. More specifically, the present invention intends to provide a cordless telephone in which the operating unit of the cordless telephone is locked by a lock operation so that the cordless telephone does not malfunction even if the child is mischievous. It is a thing.

A cordless telephone with an operation lock function according to the present invention is a cordless telephone having one or more cordless handsets that are wirelessly connected to a parent device, and the cordless handset is an operation unit. An operating unit, a display unit that displays the operating state of the operating unit or the operating state of the operating unit, and a control unit that controls the operating unit, and a normal unit for invalidating the normal operation of the slave unit. A storage unit for storing the operation invalidation instruction information is provided in the child device. At this time, the normal operation invalidation instruction information is generated by simultaneously pressing a plurality of buttons that are not simultaneously pressed during normal operation, and is preferably generated by simultaneously pressing the * button and the # button for a predetermined time or more. To be done.

[Action]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the electrical configuration of a cordless telephone handset of the present invention. FIG. 2 is a sequence diagram showing the control procedure of the slave unit of the cordless telephone of the present invention. In order to solve the above problems, a cordless telephone handset according to the present invention has an operation unit 1 including a circuit that receives an operation.
And an operating unit 4 including a circuit for executing the operation of the slave unit and a display unit 3 including a display for displaying an operating state of the operating unit, an operating state of the operating unit, or a "normal operation disabled" state,
The control unit 2 having a control means for invalidating the normal operation of the specific slave by a predetermined operation and validating the normal operation by the predetermined operation and the specific slave are in the normal operation invalid state or the normal operation valid state. There is provided a storage unit 5 for storing whether or not In the embodiment of FIG. 1, in order to invalidate the normal operation of the illustrated child device, a predetermined operation (lock operation) on the operation unit 1 is performed by, for example, pressing * and # simultaneously for 1 second or more. The normal operation lock information is generated, the normal operation invalid state can be stored in the storage unit 5, and the state can be displayed on the display unit 3 (for example, the normal operation is locked). The display of the locked state on the display unit 3 is not always necessary. When the normal operation is disabled, the control unit 2 ignores normal operations other than the predetermined operation from the operation unit 1 and does not transmit information from the control unit 2 to the operation unit 4. In the embodiment of FIG. 1, in order to change the normal operation of the illustrated slave unit from the invalid state to the valid state, as a predetermined operation (unlock operation), for example, * and # are simultaneously pressed for 1 second or more. To be achieved. This unlocking operation may be the same as or different from the locking operation. When the lock release operation and the lock operation are the same operation, the lock state and the lock release state are switched each time the normal operation lock information is generated. In the case where the unlocking operation and the locking operation are different operations, the locked state and the unlocked state are selected according to the generated normal operation lock information. When accepting the unlock operation, the normal state is stored in the storage unit 5.
And the display of the display unit 3 is returned to the normal state.

Since the present invention has the above-mentioned structure, it is impossible to return the disabled handset unit to the normal operation state without performing a predetermined operation. It is possible to prevent an inconvenient operation due to a mischievous operation (such as capturing an outside line due to mischief, power consumption, etc.). Further, since the cordless telephone handset of the present invention can be set to disable or enable the normal operation by a predetermined operation, the use of the handset is restricted to those who do not know the predetermined operation (children, etc.). effective. Further, according to the present invention, since the storage unit for the valid / invalid state of the normal operation is provided in the slave unit, information is not transmitted to the operation unit of the slave unit, so that the effective lock of the normal operation is achieved. is there.
