Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device for surely transmitting the setting of an unconditional transfer mode and providing a comfortable working environment when the unconditional transfer mode is set.

[0002]

2. Description of the Related Art There is known a facsimile apparatus configured as a multifunction machine having a copy function. Such a multifunction device generally includes an auto document feeder (ADF) and a flatbed scanner (FB).
A flatbed-type original placing table for reading which functions as S) is provided.

When copying an original with a multifunction peripheral, a copy operation is performed.
After specifying the reading mode (resolution) according to the number of copies and the type of the original (image information of ordinary characters or figures or a photograph), press the start button to start reading the original, and Copies are printed on copies of recording paper.

[0004] In a communication terminal device such as the multifunction peripheral,
Known are those having a call function and those having a function of receiving an image transmitted from a caller and transferring the received image to a preset destination. When transferring an image, the communication terminal receives the image transmitted from the transmission source through the exchange and stores it in the image memory. The communication terminal device serves as a transfer source and transfers the received image to the transfer destination through the exchange as necessary.

Further, in a communication terminal device having a call function, a call from a caller received by the communication terminal device may be transferred to a transfer destination by using a transfer function provided by a line carrier. it can. The communication terminal device sequentially transfers calls that arrive at different times to respective designated transfer destinations.

An unconditional transfer mode can be used as a call transfer method. In the unconditional transfer mode, when there is a call from the caller, the exchange directly transfers the call to the transfer destination without calling the transfer source telephone.

As described above, when the unconditional transfer mode is set, the call from the caller is automatically transferred to the transfer destination. However, when the unconditional transfer mode is set, the call is transferred. The original cannot talk to the caller. For this reason, a call transfer warning signal (TIR) is sent to the transfer source to notify that the unconditional transfer mode is set.

[0008]

By the way, in spite of setting the unconditional transfer mode in the exchange, the user sometimes forgets the setting of the unconditional transfer mode. In such a case, when the user goes to the office or goes out, even if a TIR signal is transmitted to the communication terminal device, it cannot be confirmed. Therefore, there is a problem that the user is not aware that unintended call transfer is being performed.

When the unconditional transfer mode is set, the bell of the TIR signal sounds for a few seconds as described above. Therefore, when the user is aware of the setting of the unconditional transfer mode, the bell sound of the TIR signal is useless, and there is a problem in the work environment. Further, there is a problem that the bell sound of the TIR signal is erroneously recognized as a bell sound of a normal telephone.

FIG. 4 is a flowchart showing the processing procedure of the present invention. Next, this flowchart will be described.

(1) The processing program is started in step S1, and the line is disconnected from the telephone in the processing in step S2. Next, it is determined whether or not the incoming signal CI has been detected in the process of step S3. If this determination result is NO (hereinafter, abbreviated as N), the process enters a standby state of the process of step S3.

(2) The result of the determination in step S3 is YES
If it is (hereinafter abbreviated as Y), the process proceeds to step S4, and it is determined whether or not a call transfer warning signal (TIR) is detected. If the result of this determination is N, then the line is connected to the telephone in the processing of step S5. The bell rings at this time. Next, it is determined whether or not the handset is lifted in the process of step S6, that is, whether or not the handset is lifted. If the result of this determination is N, the process enters a standby state for the processing of step S6.

(3) If the result of the determination in step S6 becomes Y due to the lifting of the handset, then a call is made in step S7, and then in step S8 whether or not the telephone is off-hook, that is, whether or not a call is in progress Is determined. If the determination result is Y, the process of step S8 is continued. If the determination result of step S8 becomes N at the end of the call, the program ends in the process of step S14.

(4) In the process of step S4,
When the TIR signal is detected and the result of this determination is Y, the process proceeds to step S9 to determine whether or not the TIR signal has ended. If the decision result in the step S9 is N, the process in the step S9 is continued until the TIR signal ends.

As described above, in the present invention, when the determination result in step S4 is N, that is, when the TIR signal is not detected, the bell is sounded in the processing in step S5. However, when the determination result of step S4 is Y, that is, when the TIR signal is detected, the process proceeds to step S9 without ringing the bell. For this reason, the working environment can be kept favorable.

(5) When the TIR signal ends, step S
The determination result at 9 is Y, and subsequently, the process proceeds to step S10 to dial the transfer notification number registered in the storage unit of the communication terminal device. Next, in step S11,
It is determined whether there is a response from the other party (the destination 3a in FIG. 1). If this determination result is N, step S11
Is repeated. Therefore, even if the user is going to or going out of the office department, the communication terminal device is set to the unconditional transfer mode and the call from the caller is being transferred to the transfer destination. Can be transmitted.

(6) If the result of the determination in step S11 is Y, then in step S12, a message of "there was an unconditional transfer" is given by voice. Subsequently, the line is disconnected in the processing of step S13, and the processing program ends in step S14. As described above, the fact that the unconditional transfer mode is set in the communication terminal device 3 is notified to the user by a voice message, so that the user can be clearly recognized.
