Description of the Related Art Recently, a dial-in service has been widely used, but the present applicant has previously proposed a facsimile apparatus having a dial-in processing unit for performing a dial-in process. In such a facsimile apparatus with a dial-in function, a dial-in service can be received without purchasing a dedicated dial-in adapter separately from the facsimile apparatus. That is, in such a facsimile apparatus, another telephone other than the facsimile apparatus is additionally connected to one telephone line to which the facsimile apparatus is connected, and a dial-in number assigned to these telephones is transmitted to the dial-in processing unit. If you register in the storage unit,
When a call is made from outside, a facsimile machine or telephone corresponding to the called number can be connected to a telephone line to make a call or call.

[0003]

However, in the above-described apparatus, data of a dial-in number of a facsimile apparatus or another telephone is transmitted by operating a dip switch provided in a dial-in processing circuit or operating a numeric keypad. The setting was input. Therefore, in addition to the key operation unit for the facsimile, the key operation unit for the dial-in processing unit also exists as the entire facsimile device, and the number of operation keys increases, and the usability is deteriorated.
There were drawbacks, such as an increase in manufacturing cost due to the complicated structure of the key operation unit. The present invention has been proposed in view of the above points, and it is an object of the present invention to provide a facsimile apparatus with a dial-in function that can simplify the structure of a key operation unit and can facilitate key operation. The purpose is.

[0004]

A facsimile apparatus with a dial-in function according to the present invention proposed to achieve the above object has a key operation unit, a storage unit for storing data input by the key operation unit, A facsimile apparatus having a facsimile apparatus main body section and a dial-in processing section, which can be connected to another communication terminal, wherein the dial-in processing section receives a call from a telephone exchange,
A function of connecting the facsimile apparatus main body or the other communication terminal corresponding to the call number to a telephone line with reference to a dial-in number registered in advance in the storage unit, It is characterized in that data registration of a dial-in number and setting of a dial-in standby mode can be performed by operating the key operation unit.

[0005]

In the facsimile apparatus with a dial-in function according to the present invention, the facsimile number as well as the dial-in numbers of the other communication terminals connected to the dial-in processing section can be used. By operating the key operation unit, the information can be input to the storage unit and registered, and thereafter, the dial-in processing function can be exhibited. Therefore, there is no need to provide a key operation unit dedicated to the dial-in processing unit separately from the key operation unit for the facsimile.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of a hardware configuration of a facsimile apparatus with a dial-in function F according to the present invention, FIG. 2 is a time chart showing an example of a general dial-in processing procedure, and FIG. FIG. 9 is an explanatory diagram illustrating an example of a procedure for registering data. The facsimile apparatus F shown in FIG. 1 is different from a facsimile Fa that exhibits a facsimile communication function,
Telephone D connected to external connection terminals TA and TB
1, a dial-in processing unit A for switching and controlling one telephone line L is provided in an integrated state, and these two signal processing units 2 are shared.

Here, the facsimile Fa is composed of a facsimile communication control unit 11 including a dial signal transmission circuit 11a and a modem 11b, a key operation unit 12, an image reading unit 13,
Display unit 1 including print output unit 15 and liquid crystal display
6 and a storage unit 14 including a RAM and a ROM. Of these, the key operation unit 12 is a facsimile F
Not only does it have a function for operating a, but it also has a function of registering the dial-in numbers assigned to the facsimile Fa and the telephones D1 and D2 in the RAM of the storage unit 14. That is, the key operation unit 12 performs a specific function key operation or a one-touch key operation to select a dial-in number registration mode, and then performs a predetermined operation described later to dial the facsimile Fa and the telephones D1 and D2. It is possible to register an in number. When the key is operated, the display unit 16
Is configured to display the operation procedure.

On the other hand, the dial-in processing section A includes a changeover switch 1 for switching and connecting the facsimile Fa and one of the telephones D1 and D2 to the telephone line L, and an NC switch 3 for connecting and disconnecting the telephone line L. , And various circuits described later. Here, the NC switch 3
As will be described later, after receiving a dial-in call from the telephone exchange, the telephone line is temporarily cut off. That is, as shown in FIG. 2, the dial-in processing unit A transmits a predetermined call signal S1 (16 Hz) transmitted from the telephone exchange after calling.
Is detected by the ringing signal detection circuit 6, the changeover switch 1 is turned off from the off contact a to the facsimile Fa.
Is switched to the connected contact b. When the push signal detecting circuit 7 detects the push tone signal S2 (DTMF) transmitted from the telephone exchange thereafter, the signal processing unit 2 decodes the calling number, that is, the dial-in number from the push tone signal. I do. Then, the signal processing unit 2 reads out and refers to the data of the dial-in number registered in the storage unit 14 at that time, and determines whether the incoming dial-in number is any of the dial-in numbers of the facsimile Fa and the telephones D1 and D2. It is configured to judge whether the numbers correspond to each other and to control the changeover switch 1 to connect the terminal corresponding to the number to the telephone line L.

When the called object is a facsimile Fa, the dial-in processing section A once opens the NC switch 3 and then closes the NC switch 3 again while keeping the changeover switch 1 connected to the contact point b. Thereafter, the line connection state between the telephone line L and the facsimile Fa is maintained. Such a temporary release operation of the line performed by the NC switch 3 is one of the line controls necessary for receiving the dial-in service. The facsimile machine F is finally connected to the line. Therefore, the facsimile Fa starts facsimile communication in accordance with a normal facsimile communication procedure thereafter.

On the other hand, the callees are telephones D1, D
2, the dial-in processing unit A connects the changeover switch 1 to one of the contacts c and d,
The C switch 3 is opened to temporarily open the telephone line, and in this state, the pseudo call signal generation circuit 5 outputs the pseudo call signal S3. Then, when the off-hook detection circuit 4 detects the off-hook by picking up the handsets of the telephones D1 and D2, the NC switch 3 is returned to the original closed state, and control is performed so that a telephone call can be made.

Next, an example of use of the facsimile apparatus F and its operation will be described. First, at the time of use, the key operation unit 12 is operated in advance, and the data of the dial-in number of each of the facsimile Fa and the telephones D1, D2 is registered in the storage unit 14. What is necessary is just to perform according to the display of the display part 16 as shown by 100-114. That is, first, after the dial-in registration mode is set by the operation key or the dedicated one-touch key operation, the communication terminals Fa, D1, and D2 are set to the dial-in standby mode or the normal standby mode. Select When the normal is selected, the process returns to the normal standby mode (step 111 in FIG. 3). When the dial-in standby is selected, the process shifts to the number registration mode.

Then, in the case of initial registration, a four-digit dial-in number is sequentially input by operating a ten-key pad. In the case of an incorrect input, the "cancel" key can be used to correct it. When the input is completed, the "register" key is operated. Next, the user selects which of the facsimile Fa and the telephones D1, D2 the registered number is to be assigned, and operates the "register" key (steps 105-1).
08). To subsequently register a dial number, the user may operate the "register" key in step 109 and repeat the above-described procedure (steps 103 to 108). To end the registration, the "stop" key may be operated, and from the end of the registration, the facsimile machine F automatically enters the dial-in standby mode. If the dial-in number has already been registered in the storage unit 14, the registered dial-in number is displayed on the display unit 16. To change the number or the terminal to which the number is assigned, select "Select". After selecting the number with the key, the "cancel" key is operated, and then a new dial-in number may be input or a terminal may be assigned in the same procedure as the initial registration procedure described above.

According to the above key operation function, the display unit 16
The data registration work can be performed while looking at the guidance items of the above, which is convenient, and there is no operational error. Moreover, since it is not necessary to provide the dial-in processing unit A with a key operation unit for dial-in number registration, the entire key operation unit structure can be simplified, which is convenient.

Further, when the dial-in processing function of the facsimile apparatus F is simplified, first, after the above-described dial-in number data is registered, when a call is made from an external communication terminal, the call is first transmitted from the telephone exchange. When the incoming call signal S1 is detected by the call signal detection circuit 6, the changeover switch 1 is switched to the contact b to receive the incoming call. Further, the push tone signal S2 transmitted from the telephone exchange thereafter is detected and demodulated by the push signal detection circuit 7, so that the calling number is decoded by the signal processing unit 2. The call number data is compared with the dial-in number data registered in the RAM of the storage unit 14,
If the calling number (the incoming dial-in number) is the number of the facsimile Fa, the contact of the changeover switch 1 remains at b, the NC switch 3 is opened once and then returns to the line connection state, and the facsimile Fa automatically receives the incoming call. I do. Thereafter, facsimile communication is performed according to a normal facsimile communication procedure.

On the other hand, when the incoming dial-in number is, for example, the number of the telephone D1, the changeover switch 1 is set to the contact c.
And the pseudo call signal generation circuit 5 sends a pseudo call signal S3 to the telephone D1 with the other NC switches 3 open. Meanwhile, the calling party is hearing a ringback tone. Next, telephone D
When the handset 1 is picked up, this is detected by the off-hook detection circuit 4 of the dial-in processing unit A, and the NC switch 3 is switched to the contact point a to return to the closed state, and the telephone D1 is connected to the telephone line L Once connected, you can talk normally. Steps 200 to 218 in the flowchart of FIG. 4 show the operation procedure of the above-described series of dial-in processing.

FIG. 5 is a block diagram showing another embodiment of the facsimile apparatus with a dial-in processing function according to the present invention. The facsimile apparatus FA shown in FIG. 1 includes a dial-in processing unit Aa and a facsimile
The signal processing units 2a and 2b are provided with storage units 14a and 14b. In the present invention, two storage units 14a and 14b are used as storage units for registering dial-in numbers. 14b may be used. That is, data input by the operation of the key operation unit 12 is transmitted from the signal processing unit 2b of the facsimile Fb to the signal processing unit 2a on the dial-in processing unit Aa side and stored in the storage unit 14a, or as another method. , May be stored directly in the storage unit 14b of the facsimile Fb. Even in the latter case, the registered data can be read from the signal processing unit 2a of the dial-in processing unit Aa, and there is no problem with the dial-in processing function. As described above, the facsimile apparatus with a dial-in processing function according to the present invention may have any configuration regardless of whether the facsimile and the dial-in processing unit are integrated or separate. However, as shown in FIG. 1, there is an advantage that if the both are integrated, the hardware configuration of the entire facsimile apparatus can be further simplified and downsized.

[0017]

As will be understood from the above description, according to the facsimile apparatus with a dial-in function according to the present invention, the dial-in numbers of various communication terminals can be registered with the key operation unit provided in the facsimile. Therefore, it is not necessary to separately provide a dedicated key operation unit in the dial-in processing unit unlike the related art, and a special effect that the structure can be simplified and the key operability can be improved can be obtained. Also,
By using the key operation unit of the facsimile, key operation using the display unit provided in the facsimile becomes possible, and the key operability can be further improved.
