Abstract

PURPOSE:To evade accidents by on-hooking a slave unit unless the slave unit performs a prescribed operation within a fixed time by using a timer when a second telephone set is in an on-hook state when the slave unit is off-hooked. CONSTITUTION:Whether or not the slave unit 11 is off-hooked is confirmed and in the case of being off-hooked, the prescribed time for managing the off- hook state of the slave unit 11 is stored in a memory part 6. Then, whether or not a branch telephone set 12 is in the on-hook state is confirmed by the state of input from a branch detection circuit 2. In the case of the on-hook state, counting the time of the off-hook state of the slave unit 11 is started by using a timer part 7. Further, whether or not the slave unit 11 performs dial calling through a dial transmission part 4 during counting is monitored. Whether or not the prescribed time stored in the memory part 6 passes is confirmed when the slave unit 11 does not perform the dial calling and when the prescribed time passes, the on-hooking processing of the slave unit 11 is performed and a standby state is returned.

However, in the cordless telephone device having the above-described structure, when the handset is picked up, the outside line and the handset are in a call state for a certain period of time, but the line is disconnected after a certain period of time. Will end up. Also, when transferring from a branch phone to a handset, the person who was talking on the branch phone, after confirming the call of the handset, left the handset without instructing the handset to dial. In the case of (on-hook state), the line may be disconnected after a certain period of time.

The present invention has been made in view of the above circumstances, and provides a telephone device capable of easily and reliably performing a hold transfer between a slave unit constituting a first telephone set and a second telephone set. The purpose is to do.

[0006]

In order to achieve the above object, the present invention is directed to a first telephone comprising a base unit and a handset wirelessly connected to each other, and a telephone line common to the base unit. In a telephone device including a second telephone, the timer and the second telephone are started when the second telephone is on-hook when the handset is off-hook, the timer is started, and the child is set within a predetermined time. First processing means for performing on-hook processing of the slave unit if a predetermined operation of the slave unit is not performed, and activating the timer if the second telephone is in the off-hook state when the slave unit is off-hook. And second processing means for immediately performing processing for immediately setting the slave unit in a call-ready state.

[0007]

According to the above construction, the master unit and the slave unit which compose the first telephone in the present telephone device are wirelessly connected, and the master unit and the second telephone are connected to a common telephone line. In addition, this telephone device is provided with a timer for time management of the off-hook state of the child device.

On the other hand, the first processing means starts the timer when the second telephone is on-hook when the slave is turned off. Then, if a predetermined operation of the child device is not performed within a certain time, an on-hook process is performed. Also, the second processing means, when the second handset is off-hook when the handset is off-hook,
A process for immediately making the mobile device ready for a call is performed without operating the timer.

As a result of the above processing, an accident that the telephone cannot be hung up due to the continuation of the off-hook state of the handset is avoided, and the hold transfer between the handset and the second telephone is avoided. However, it can be performed quickly and reliably without any operation.
