Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication device, and particularly to a communication device that is connected to a voice line and performs non-voice communication and voice communication using a predetermined method.

[Prior Art] Conventionally, in communication devices such as facsimile machines connected to a telephone line, a so-called call reservation function has been known that requests a call with an operator on the other side during non-voice communication.

For example, a facsimile machine is provided with an input means called a call reservation key, operator call button, telephone key, etc. in order to reserve a call.

The above-mentioned input means are often configured to perform a so-called toggle operation. That is, each time the operation is repeated, an LED or the like provided in the vicinity is turned on or off, and when the LED is turned on, it is indicated that a call has been set for the operator of the other station.

[Problems to be Solved by the Invention] In fact, in a facsimile device that uses the CCITT procedure, when a call reservation is made as described above, the device transmits the original image and then sends a PRI-EOP signal to the other party. When the side receives this signal, it starts calling the operator using a pseudo bell tone or the like.

When the operator on the other side raises the handset and operates the input means configured in the same way as on the reservation side, PIP/PIN
A signal is sent back.

When the reservation side receives the PIP/PIN signal, it starts calling the operator using a pseudo bell sound or the like.

The operator on the reservation side knows from this ring tone that the operator on the other side has answered, takes the handset off-hook, and operates the input means again to switch the line, which is the first time. You can now make calls.

As described above, the procedure for making a reservation for a call is quite complicated, and a call cannot be made unless both operators are familiar with the procedure. In the past, there were many cases where one of the operators made a mistake in the operating procedure and was unable to make a call.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a communication device that is connected to a voice line and performs non-voice communication and voice communication using a predetermined method. a handset and a means for detecting a hook state of the handset, and when an off-footer state of the handset is detected during the non-voice communication, preparation processing for voice communication with an operator of a partner station is provided. We adopted a configuration that performs the following.

[Function] According to the above configuration, it is possible to make a call reservation simply by lifting the handset from the hook, without requiring any troublesome operation of switches or keys.

According to the above control procedure, by taking the handset off-hook during non-voice communication, it is possible to shift to the call mode without performing any troublesome switch operations.

According to the above procedure, transition to voice communication is possible at all communication stages immediately after a call is made. Additionally, the party receiving the call reservation can also switch to call mode by simply lifting the handset.

In addition, since the operator's response is determined by detecting that the operator is looking at the receiver, the operator's response can be reliably detected without the need for the troublesome switch operations required in the past. .

In the above embodiment, when off-hook is performed after a selection signal is generated in an on-hook state and an initial identification signal is detected from the other party, it is determined that it is a call request before image communication, and an initial identification signal is received from the other party. If the user went off-hook before, voice communication is performed. However, the control state may be reversed, such that the off-hook before receiving the initial identification signal is used to request a pre-call call, and the off-hook after receiving the initial identification signal is used to switch to a call mode in which image communication is not performed.

Although a facsimile machine has been exemplified above, it goes without saying that the present invention can also be applied to communication devices using other telephone lines.

[Effects of the Invention] As is clear from the above, according to the present invention, in a communication device that is connected to a voice line and performs non-voice communication and voice communication using a predetermined method, a handset for voice communication and a handset for voice communication; A configuration is adopted in which means is provided for detecting a hook state of the handset, and when an off-footer state of the handset is detected during the non-voice communication, preparation processing for voice communication with an operator of a partner station is performed. Therefore, it is possible to provide a communication device with excellent operability in which a call reservation can be made simply by lifting the handset from the hook without requiring troublesome operation of switches or keys.
