[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone set comprising a combination of a master unit and a slave unit.

[0002]

2. Description of the Related Art In such a telephone, a storage unit for a child device is formed on a surface of a parent device connected to a telephone line.
The slave unit has, on its surface, a receiver unit with a built-in speaker, a transmitter unit with a built-in microphone, and an operation key group for inputting a telephone number, and usually lifts the slave unit from the base unit. In this state, it is possible to make a call relaying the master unit. still,
The child device storage part of the parent device is formed in a structure capable of storing the child device in a posture in which the surface of the child device on which the operation key group is arranged faces the parent device. By storing the slave unit in the master unit in this attitude, the pair of charging terminals provided on the slave unit come into contact with the pair of charging output terminals provided on the master unit, and the slave unit is charged.

[0003] In recent years, not only in a digital telephone network but also in an analog telephone network, a system for notifying the telephone number of a caller at the time of an incoming call has become feasible. In this case, the telephone number of the caller is displayed on a display installed in the parent device or the child device. In addition, in a telephone including a master unit and a slave unit, at the time of outgoing call, it is possible to input a telephone number by operating the operation keys of the slave unit while the slave unit is stored in the master unit, and at the time of an incoming call,
There has been developed a telephone that allows a user to talk by operating a specific key while the child device is stored in the parent device.

In the above-described telephone, the first storage position in which the surface of the slave unit in which the operation keys are arranged is directed toward the base unit, and conversely, the rear surface of the slave unit is directed toward the base unit. A structure is adopted in which the slave unit can be stored in the master unit with compatibility in both the second storage position allowing observation and operation of the operation key group. This configuration has a circuit configuration that allows the child device to be charged regardless of the storage posture of the child device in the parent device.
