Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a two-line storage type communication device, and more particularly to a two-line storage type communication device that accommodates two lines.

(Prior Art) Examples of two-line storage type communication devices that accommodate two lines include a two-line storage type facsimile machine and a two-line storage type telephone set. These two-line storage type communication devices are usually equipped with a handset for making calls, and one of the two lines can be switched to the handset and connected to make a call.

Conventionally, in these two-line storage type communication devices, if a call is received on the other line while a call is being made using one line, the operator is notified of the incoming call by a buzzer or a flashing lamp. When the operator knows that there is an incoming call from the buzzer sound or flashing lamp, the operator puts the current line on hold or disconnects the line and responds to the incoming call by switching to the other line that received the call.

(Problem to be Solved by the Invention) However, in such a conventional two-line storage type communication device, if a call is received on one of the two lines while the other line receives a call, the incoming call is simply Since the call was only notified by a buzzer or a flashing lamp, there was a problem in that it was not possible to identify the person receiving the call, and it was not possible to take a prompt and appropriate response to the call.

In particular, with dual-line facsimile devices, it is not clear whether the recipient of a new call is a facsimile device or a person (telephone), resulting in a delay in responding appropriately depending on the recipient. there were.

Also, if you are talking on one of the two lines and receive a call on the other line, the other party will not know that there is an incoming call, and will explain the incoming call to the other party in a conversation. There was a problem in that it was impossible to respond quickly.

Furthermore, if there are other telephones nearby, if you are talking on one line, the incoming call from the other line will only sound like a ring on the telephone itself. I had a problem figuring out if it was an incoming call.

(Object of the Invention) Therefore, the invention as claimed in claim 1 is such that when a new call arrives on another line during a call using a handset, the signal tone of either line can be monitored at the operator's selection. This is a two-line storage type that allows you to quickly determine who is receiving a new call through the monitoring means or handset, and to take prompt and appropriate responses to new calls. The purpose is to provide communication equipment.

Further, the invention as claimed in claim 2 provides that, when a new call arrives on another line during a call using the handset, a predetermined tone signal is sent to the line in use, so that the incoming call is detected on the other line. The company's sales pitch is to make both operators aware of this via a tone signal from the handset so that they can be reliably notified of a new incoming call and take prompt and appropriate action.

(Structure of the Invention) In order to achieve the above object, the invention according to claim 1 provides a two-line system that houses two lines and includes a ringing detection means for detecting ringing of each line, and a telephone handset. The storage type communication device is provided with a monitor means for monitoring the signal tone of the line, and a switching means for selecting the line to be monitored by the monitor means from among the two lines, and when one line is being used during a call using the handset. If there is ringing on the other line, the operator selects a switching means to monitor the signal tone on one line.

Further, the invention according to claim 2 provides a two-line storage type communication device that houses two lines and includes a ringing detection means for detecting ringing of each line, and a handset for telephone calls. A tone generating means is provided to send out a predetermined tone signal to notify the user that the tone is in use, and when one line is in use with a handset and there is ringing on the other line, the tone generating means is activated and the tone is activated. It is characterized by transmitting to the same line.
