Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an answering machine equipped with an answering machine that can be operated from another telephone.

(Prior Art) In an answering machine, a control signal for the answering machine is inputted to the answering machine control means through keys on a dial keypad to perform various operations on the answering machine. In some devices, the means receives control signals from the telephone line and supplies them to the answering unit control means.

This allows you to perform various operations on the answering machine, such as recording an answering message, playing back messages recorded when receiving an automatic call, and canceling the answering machine setting, through the dial keypad of another telephone. It is possible.

However, in other words, this answering machine can only be operated by the user at the user's side or by using another telephone, which has traditionally been inconvenient in some cases.

In other words, in a store that is separated from a residence and adjacent to the store, an answering machine is installed in the store, and when the store is open, when taking orders over the phone, a recording and playback function is used to record and play back the contents of the call so that no notes are taken. In this case, after the store is closed, the answering function of the answering machine is used to accept telephone orders.

In this case, when checking the contents of an answering machine's answering machine while the store is closed, the user must either go to the grounded location of the answering machine and operate it directly, or operate it using another outside line telephone.

However, in cases where a store and a residence are in different buildings even though they are on the same block, it is troublesome to go to the grounding location of the telephone.

In addition, for other outside telephones, if there is only one subscriber line, an outside public telephone must be used or another subscriber line must be installed.

If you are just making regular calls, you can simply connect another telephone in parallel to the subscriber line to which the answering machine is connected, so it is economical to install a separate subscriber line, especially in the case of small stores. This is usually not done for various reasons.

(Problem to be Solved by the Invention) As described above, with conventional answering machines, when attempting to operate the answering machine unit with another telephone, the operation can only be done using an outside line, which causes inconvenience. Ta.

Under the control of the switch control means, when the answering mode is set, the connection terminal section is connected to the control signal receiving means, and the call request signal from the other telephone is received during the answering answering mode. When the control signal receiving means receives the control signal, the communication mode is set and the connection terminal section is connected to the telephone line only while the hook detection signal indicates off-hook.

(Function) According to the present invention, when the answering mode is set, the telephone connection terminal section is connected to the control signal receiving means.

Therefore, the answering unit is controlled by an answering unit control signal from another telephone connected to the terminal section. In addition, the call request signal allows the telephone connection terminal to be connected to an electrical line while another telephone is off-hook, making it possible to make two calls using the telephone line, and also to prevent the other telephone from going on-hook. For example, the telephone connection terminal section is connected to the control signal receiving means.
