Abstract

PURPOSE:To attain facsimile communication such as polling reception by selecting one of plural selection signals based on a detection output representing the presence of an original and the hook state when one of the plural selection signals stored with respect to one input data is selected and selecting a facsimile selection signal even when no transmission original is available. CONSTITUTION:A system control section 1 discriminates the state of a handset 13 by an off-hook sensor 14 through the depression of a selector switch 4A of an operation section 4. In the case of on-hook, an original presence sensor 10 discriminates the presence of a transmission original 11. When the original is in existence, a destination telephone number for facsimile communication is read from a RAM 6 and a selection signal is sent from an NCU 8 to a telephone line 12 to implement prescribed transmission. When no original is in existence, the destination telephone number is read and the reception is implemented. On the other hand, in the case of off-hook, the presence of the original 11 is discriminated. When no original is placed, a talking destination telephone number is read and the usual telephone set mode is set. A selection signal is properly selected to implement the communication in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine having an auto-dial function.

[Prior Art] Conventionally, two selection signals, one for facsimile and one for telephone, are set for one auto-dial key, and the selection signal for facsimile or telephone is automatically set based on the setting status of the original to be sent. A facsimile machine is known that selectively transmits a selection signal.

That is, when it is determined that there is a document on the document table, a selection signal for facsimile is sent out, and when it is determined that there is no document on the document table, a selection signal for telephone communication is sent out.

[The problem that the invention aims to solve! 4] However, in such a facsimile device, the facsimile selection signal and the call selection signal are automatically selected based on the presence or absence of a document, so the facsimile selection signal is sent and polling reception is performed. Even if an attempt is made to do so, in this case there is no document to send, so the facsimile selection signal will not be selected. therefore,
The drawback was that polling reception could not be performed using the auto-dial function.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus that can properly select a selection signal for facsimile and perform facsimile communication such as polling reception even when there is no document to be transmitted.

[Means for Solving the Problems] The present invention provides a plurality of key input means for inputting communication destination selection, and inputting different predetermined types of data for each piece of data input by these key input means. A storage means storing selection signal data, a hook state detection means for detecting whether the hook switch is on-hook or off-hook, a document detection means for detecting the presence or absence of a document on the document table, and the key input means. selection signal data reading means for reading out one of the selection signal data corresponding to the input data from the storage means based on the detection output from each of the detection means when one data is input; The present invention is characterized by comprising selection signal sending means for sending out a selection signal to a communication line in accordance with selection signal data read from the storage means by the means.

[Function] In the present invention, when selecting one of a plurality of selection signals stored for one input data, by selecting from two detection outputs: document presence/absence and hook state, Even when there is no document to be transmitted, it is possible to appropriately select a facsimile selection signal and effectively perform facsimile communication such as polling reception.

[Embodiment] FIG. 1 is a block diagram showing a facsimile apparatus according to an embodiment of the present invention.

In the figure, the system control unit 1 is composed of, for example, a microcomputer, a storage circuit, and the like.

It includes a ROMIA in which control procedures as shown in FIG. 2 are stored.

The reading unit 2 includes a CCD image sensor and the like that reads the transmission document 11 conveyed by the document conveyance roller 9.

Note that the transmission document 11 is detected by the document presence/absence sensor 10 at a predetermined timing as described later.

The recording unit 3 records, for example, an image electrostatically on recording paper in accordance with the received image signal.

The operation section 4 has various operation keys arranged thereon, and is particularly provided with a selection switch 4A that executes the functions of the present invention.

The display unit 5 displays status displays, alarm displays, and the like.

Note that the operation section 4 and the display section 5 may be configured as one operation display section.

The RAM 6 is a non-volatile RAM in which the telephone number of the other party is registered. Note that a volatile memory backed up by a battery may be used as the RAM 6.

Further, a modem (modem M) 7 modulates and demodulates transmitted and received signals.

The NCU (network control unit) 8 has a function of transmitting a 1 selection signal (pulse or tone dialer), and not only performs automatic call reception operation and line control operation by detecting a ring tone, but also performs; Telephone line 1
2, a selection signal sending operation is performed.

The handset 13 is used for making phone calls, and the off-hook detection sensor 14 is used to detect when the handset 13 is off-hook.

FIG. 2 is a flowchart showing an example of the operation of this embodiment.

Note that the non-volatile RAM 6 stores the destination optical telephone number "X" for facsimile in correspondence with the selection switch 4A of the operation section 4.
” and the telephone number of the other party for the call “Y” are assigned and registered in advance.

First, it is determined whether or not the selection switch 4A disposed on the operation unit 4 is pressed (si), and when it is pressed, the system control unit 1 determines whether the handset 13 goes off-hook or not depending on the output of the off-hook detection sensor 14. On-hook is determined (S2).

If the off-hook detection sensor 14 determines that the handset 13 is on-to-second, then the system control unit 1 determines whether or not there is a transmission document 11 based on the output of the document presence/absence sensor 10 (S3).

Here, if it is determined that there is a document to be sent, the non-volatile RA
Reads the destination telephone number "X" for facsimile from M6, sends a selection signal for that telephone number from NUC8 to telephone line 12, and after the line is connected, the operation mode changes to facsimile transmission mode and performs a predetermined transmission operation. (S4).

In addition, if it is determined in S3 that there is no document, the destination phone number for facsimile "X" is stored in the non-volatile RAM 6.
is read out, a selection signal for the telephone number is sent from the NCU 3 to the telephone line 12, and after connection, the operation mode changes to facsimile polling reception mode and a reception operation is performed (S5).

On the other hand, when the off-hook detection sensor 14 determines that the handset 13 is off-hook, the system control unit l determines the presence or absence of the transmitted original 11 according to the output of the original presence/absence sensor 10 (S6). If it is determined that there is, the non-volatile RAM
The facsimile destination telephone number "x?" is read out from NCU 3 and the selection signal for that telephone number is sent from NCU 3 to telephone line 1.
After the line is connected, the operation mode becomes facsimile manual transmission mode and a predetermined transmission operation is performed (S7).

If it is determined in S6 that there is no document, the telephone number "Y" of the other party for the call is read from the nonvolatile RAM 6, a selection signal for that telephone number is sent from the NCU 3 to the telephone line 12, and the operation is performed. The mode changes to normal phone mode (
S8).

As described above, according to this embodiment, by providing the presence or absence of a document and the hook status as conditions for selecting the selection signal, the facsimile polling reception mode and facsimile manual transmission mode are selected using the auto dial function. can do.

In FIG. 2, the off-hook detection of the handset in S2 and the detection of the presence or absence of a document in S3 and S6 may be interchanged.
