Abstract

PURPOSE:To easily and securely switch a line to a facsimile side without using hooking operation as a line switching means by entering into a CNG or CED reception state automatically. CONSTITUTION:By serial operation wherein an operator lifts a receiver, hears a facsimile signal tone, and puts the receiver back, a CML relay 1 switches the line from the side of a telephone set 6 to the side of facsimile equipment 5 in an on-hook state after the switching of the output of a hook detecting circuit 2 from the off-hook state to the on-hook state. After the line is switched, an identification signal detecting circuit 3 monitors the line to detect CNG or CED. When the CNG or CED is detected, facsimile operation is started as it is and when a facsimile identification signal is not detected in constant-time monitoring, the line is released. Consequently, the line can easily and securely be switched to the facsimile side without requiring any hooking operation.

2. Description of the Related Art Conventionally, in facsimile machines used in small-scale offices, shops, etc., there are many cases in which a telephone and a facsimile are commonly used on the same telephone line because of the cost. In such a usage environment, the reception is mainly done by the telephone, so the facsimile machine is set to the manual reception state, the telephone line is connected to the telephone side, and when the facsimile signal is received, the telephone is off-hook. In this state, the normal operation procedure is to receive the image signal after turning on the reception key of the facsimile. By the way, in offices and the like, there is a case where the telephone and the facsimile machine have to be installed apart from each other due to the space.Therefore, the telephone user has to go to the facsimile machine in order to operate the reception key of the facsimile machine. There was the annoyance of moving and operating the receive key.

All the above-mentioned devices are constructed so that they can be switched from the telephone side to the facsimile side by a hooking operation. However, the hooking operation is often performed even when the line condition is poor. There is a problem that an operator who does not know that the hooking operation is a means for switching to the facsimile performs the hooking operation and mistakenly switches the line to the facsimile even while receiving a telephone call. Not only that, but because the operation is unfamiliar, there is a problem that the hooking operation is mistakenly cut off the line.

According to such a technical means, in the on-hook state after the output of the hook detecting means is switched from off-hook to on-hook in response to a series of operations in which the operator picks up the receiver, hears the facsimile signal sound and returns the receiver. The line switching means switches the line from the telephone side to the facsimile side. After the line is switched, the identification signal detecting means monitors the line and detects CNG or CED. When CNG or CED is detected, the operation directly proceeds to the facsimile operation, but when the facsimile identification signal is not detected even after monitoring for a certain period of time, the line is opened.

Therefore, according to the present invention, since the hooking operation is not used as a means for switching the line for switching the line, there is no possibility of switching to the facsimile side or accidentally disconnecting the line by an erroneous operation. In addition, since the present invention automatically shifts to the CNG or CED receiving state after changing from off-hook to on-hook, the switching operation to the facsimile is unnecessary and reliable and smooth switching can be performed.
