Abstract

PURPOSE:To prevent malfunction from occurring by providing a means which permits or prohibits the acception of dial data from a medium from which the dial data is generated, and permitting the acceptance of the dial data in a standby state. CONSTITUTION:When a call is issued from a call issuing part 3, it is connected to an opposite machine, and transmission is started. However, since no data of a card dialer received by a light receiving part 4 is required while the transmission is performed, an interface switch is turned off just before the transmission is started. Since the data of the card dialer is required in the standby state after the transmission is completed and before it is returned to the standby state, the interface switch is turned on, and the data from the card dialer is validated. The interface switch is turned off in the case other than the standby state, and the dial data from the card dialer 9 is neglected.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication device that receives dial data from a removable medium that generates dial data and makes a call.

[Prior Art] Conventionally, this type of device receives dial data from a removable electronic telephone directory card (card dialer) and makes a call (dialing) from a dialer provided in the facsimile body. Facsimile machines are known.

The facsimile machine described above is unidirectionally controlled with respect to data from the card dialer, so the card dialer cannot be controlled from the main unit, and is configured to receive data at any time regardless of the state of the main unit. There is.

[Problems to be Solved by the Invention] However, in the conventional example described above, even if the main body side does not want to accept data from the card dialer, data is sent sequentially from the card dialer at the timing when the dial button of the power dialer is pressed. There was a drawback that it could get stuck and malfunction.

[Means for Solving the Problems] The present invention provides means for enabling or prohibiting reception of dial data from a medium that generates dial data,
This prevents malfunctions by allowing dial data to be accepted in the standby state.

[Example 1] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In the following embodiments, a facsimile machine into which a card dialer can be inserted will be explained as an example, but the present invention is applicable not only to facsimile machines but also to various communication devices such as telephones, key telephone systems, teletex, etc. can.

FIG. 1 is a block diagram showing the configuration of a facsimile machine according to this embodiment.

In the figure, ■ is the operation part for inputting the operation of the device.
Various keys are provided.

Reference numeral 2 denotes a control unit that controls the entire device, and is composed of a microcomputer (CPU), ROMSRAM, input/output interface, and other peripheral devices for the microcomputer.

Reference numeral 3 denotes a calling unit (dialer) that makes a call (dialing) to the line 8 according to dial data output from the control unit 2.

Reference numeral 4 denotes a light receiving unit for receiving dial data from the card dialer 9 through optical communication using a photodiode or the like.

Reference numeral 5 denotes a facsimile communication unit for performing facsimile communication.

Reference numeral 6 denotes a network control unit (NCU) that selectively connects the line 8 to the telephone 7 and the facsimile communication section 5, and forms a DC loop (line capture) and releases the line 8.

Further, FIG. 2 is a flowchart showing the control operation of the control section 2 of this embodiment.

The above configuration will be explained in detail below using a flow chart.

First, a calling operation is performed from the operation unit 1 to send a message to the other party's device (sl). When a call is actually made by the calling unit 3, a connection is made to the other party's machine and transmission begins. However, since the card dialer data received by the light receiving section 4 is unnecessary during transmission, the interface switch is turned off immediately before starting transmission (S2). After the transmission (s3) is completed and before returning to standby (s5), since data from the card dialer is required for standby, the interface switch is turned on to enable data from the card dialer (s4).

In addition to communication, all operations described above are performed during a state in which no calling operation is performed.

In this embodiment, the standby state is a state in which a line has not been acquired, and a state in which dialing has not yet been performed even if the handset of the telephone 7 is off-hook.

Further, the facsimile apparatus of this embodiment allows on-hook dialing of the handset, and the operating section 1 is provided with an off-hook key. When this off-hook key is pressed, the line is captured by the NCU 6, but even if no dialing is being performed in this state, it is in a standby state.

Therefore, in cases other than the above-mentioned standby state, the interface switch is turned off and the card dialer 9
Dial data from will be ignored.

As explained above, when the main unit accepts data from the card dialer (if not, the data from the card dialer is ignored), so the data from the card dialer can be used to prevent malfunctions etc. from being sent to the main unit. It becomes possible to have no influence.

Further, the present invention is not limited to the above-described embodiments, and various modifications are possible.

[Effects] As described above, according to the present invention, when receiving dial data from a removable medium and making a call, it is possible to receive dial data in a standby state, thereby preventing malfunction of the device. can do.
