Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input device for inputting data to a device that performs operations based on data stored in a memory card.

[Conventional technology]

Conventionally, some devices that perform operations based on data registered in a built-in memory use a memory card when the data to be used is not sufficient in the built-in memory.

For example, when a telephone or facsimile machine's one-touch dialing function was insufficient, some telephones and facsimile machines used a card-based electronic telephone directory to make a call.

In addition to the shooting mode and copying mode registered in the built-in memory of the main body, there were also cameras and copying machines that operated according to modes registered in a memory card.

[Problem that the invention is trying to solve]

However, when registering data in the built-in memory, the keyboard of the main body of the device is small due to space constraints, making it difficult to operate.

[Means to solve the problem]

In contrast, the present invention connects the memory card by providing a memory card-shaped data output section, a keyboard larger than the data output section, and a cable that transmits data input from the keyboard to the data output section. It is possible to improve the operability of registering data to a device that can be used.

〔Example〕

In this embodiment, an adapter (description of the embodiment) which is approximately the same size as the electronic telephone directory and has the same wireless communication function as the electronic telephone directory is attached to the part of the facsimile machine or telephone that connects to the electronic telephone directory. This adapter is equipped with an "interface section" (hereinafter referred to as an "interface section"), so that this adapter can communicate with another device such as an expansion operation section via wire.

This embodiment uses very short-distance wireless communication using infrared rays as a carrier wave and wired communication using signal lines instead of using the electrical interface as described above, so the communication contents may not be leaked to the outside or placed around the device. There is no risk of affecting other equipment being used. The wireless communication unit is advantageous in terms of cost because it uses the same device configuration that has been conventionally used for exchanging information between the electronic telephone directory and telephones and facsimile machines.

Since the interface used in this embodiment is electrically insulated, it can be connected/disconnected at any time even when the facsimile machine and the equipment to be connected to it (hereinafter referred to as the extended operation unit) are energized. be.

FIG. 1 shows an embodiment of the present invention. A facsimile machine is taken as an example of a fixed-side device. An operating section 2 is arranged on the front side of a housing 1 of the facsimile machine.

On the operation unit 2, there is a display unit 21 that displays the operating status of the facsimile machine, the called telephone number, the call duration, the current time, error status, etc. using a liquid crystal display element, etc., and key switches 22 that perform input. .

In addition to these, the facsimile apparatus of this example includes a coupling section 3 for mounting a portable electronic device 40 such as an electronic telephone directory. In this example, the facsimile machine l is connected to the coupling part 3.
A recess slightly larger than the outer shape of the electronic telephone directory 40 is provided in the operation section 2, and the electronic telephone directory 40 is inserted and connected therein. Communication between the main body 1 of the facsimile machine or telephone and the electronic telephone directory 40 is carried out optically using infrared rays as a carrier wave. A window 36 for optical communication for this purpose is provided on the bottom surface of the coupling section 3.

As shown in FIG. 9, there is also an optical communication window 46 for the same purpose on the back side of the electronic telephone directory 40. The electronic telephone directory 40 converts information such as a telephone number, a calling command, etc. into an optical signal according to an operation on the operation unit 42 on the front side, and transmits the optical signal to a facsimile machine or telephone. Also, check the status of the facsimile machine or telephone (power is off/currently communicating/
It is possible to make a call, there is an abnormality in the device, the command is inappropriate, etc.) is received as an optical signal through the window 46.

Main body of facsimile machine or telephone and electronic telephone directory 40
The reason why communication was carried out optically was as follows.

■ In the case of electrical connection, if a voltage is applied to the communication interface of either the facsimile machine l or the electronic telephone directory 40, a short circuit will occur at the connector part at the moment of joining/separating the joint parts. There is a risk of damage to the interface circuit.

Further, there is a possibility of malfunction due to noise generated at the moment the connector portion is connected/disconnected.

Further, when the two are not connected, it is necessary to provide a protective cover to protect the ink face connector from coming into contact with other conductors or dielectrics and being damaged by short circuit or static electricity.

■ When electromagnetic waves (longer wavelength than infrared rays) are used Electromagnetic waves have weaker directivity than infrared rays and are difficult to block. Furthermore, both the receiving device and the transmitting device are larger than those for infrared rays.

For the reasons mentioned above, we adopted infrared light.

The expansion operation section 5a shown in the lower left part of FIG. 1 is wired to the interface section 6 by a cable 45 made of bundled covered electric wires. The shape of the interface section 6 is that of an electronic telephone directory 40.
As seen in the figure, the back side has a similar optical communication window (in the same position and arrangement as the electronic telephone directory 4o).
(not shown) is provided.

The electrical configuration of the interface section 6 is as shown in FIG. In this example, the data unit is 8 bits (b
it), and the wireless communication section divides these 8 bits into upper 4 bits (D7 to D4) and lower 4 bits (Ds to D.) for communication.

The configuration of this part is the same for both the portable device and the facsimile machine. In the figure, for explanation purposes, the letter F is prefixed to the signal name on the facsimile machine side, and the letter T is prefixed to the signal name on the portable device side, but the meaning of the data is FD, and TD are the same. To give an overview of the signal names, D is the sending data bus, C is
is the transmitting side control line (controlbus), Q is the receiving side data bus, and A is the receiving side acknowledgment line (acknowledg).
e bus). D and C are signals transmitted from this side, and Q and A are signals received from the other side.

Although it is not a signal line, Vcc is a power supply line,
GND is a line that shares the ground side of the power supply and the signal ground.

In FIG. 2(a), inside the interface section 6 is an infrared light emitting diode (li
There are six built-in infrared phototransistors 61 and six infrared phototransistors 62 that receive infrared rays and convert them into electrical signals. A resistor 64 interposed in the middle of the signal line is simply for current limiting of i kΩ to 5Ω.

The optical interface mechanism provided on the operation unit 2 of the facsimile machine 1 or telephone is: ■ If the other party's equipment is not connected to the interface unit, The light receiving element of the circuit is exposed.

2. No light enters the light receiving element of the interface circuit.

There are two possible cases. Also, the possibility of the interface section being disconnected during communication must be considered.

■ Some of the devices connected to the interface section, such as portable devices, are powered by small-capacity batteries, and these devices are generally not subject to external stimulation such as keystrokes for a certain period of time or more. When not received, it enters a mode (called sleeve mode) in which it stops operating.

It has its own unique problems.

Therefore, in order to solve these problems, this embodiment uses a control line (C) and a response line (C) as an interface circuit.
There are two sets of A).

FIG. 3 shows an example of a timing chart of data communication signals using the interface circuit of FIG. 2(a).

As mentioned above, the first character of the signal name is used to identify whether it is on the facsimile device side or the portable device side, and is not involved in the function, so 7 is omitted. Therefore, when transmitting from the facsimile device side Add F to the beginning of the signal name in FIG. 3, and T if the signal is transmitted from a portable device.

All these signals are digital signals. Hereinafter, when the signal is in a high level (high 1 level) state, the time when the signal is in a 110-level (low 1 level) state will be expressed as O. Note that the control lines C8, C0, and response line A
,,A.

are active when all are at low level
state. In addition, the output signals (Da~D0, C1
, Co) immediately connects the corresponding receiving signal line (
It is assumed that this is reflected in the states of Q3 to Qo, A+, Ao).

In this embodiment, one unit of data is transmitted by dividing it into a plurality of small units. Then, the transmitting side device activates the transmitting side control line C1 while transmitting one unit of data,
During transmission of small units of data, the transmission side control line C8 is activated. Also, the transmitting side device has the receiving side response line A1,
Ao detects that the other party's device is ready for reception.

On the other hand, the receiving side device detects through the receiving side response line A1 that the other party's device is in the state of transmitting one unit of data, and the receiving side device detects that the other party's device is transmitting a small unit of data through the receiving side response line A1. detect that it is inside. Further, the receiving side device indicates through the transmitting side control line C1 that it is ready for reception, and notifies through the transmitting side control line co that it has responded to the request from the other party.

In FIG. 3, the transmitting side device first checks whether the receiving side response line A1 is 1 or not. If A is 0, the other party's device is transmitting data. Therefore, if A1 is 0, it means that the transmission and reception operations are not synchronized, and the state shifts to an error or A recovery waiting state. On the other hand, if A is 1, the transmitting side control section makes the transmitting side control line C1 active (0) (a). the other party's equipment,
That is, upon receiving this, the receiving side judges that since C1 is O and C6 is l, it is a transmission of valid information from the other side, and if it can receive it, it activates its own transmitting side control line C1 (0).
Make it. Then, the receiving side control line A on the transmitting side.

becomes active (0) (b). It is not activated if it is not ready for reception.

The transmitting device starts A from the falling edge of C1. Measure the time (t,) required for the temperature to drop, and even if it takes more than a certain amount of time, A. If the signal does not fall, the receiving side determines that reception is not possible.

This is to detect that the interface section 6 and the coupling section 3 on the facsimile machine side are not coupled in a normal phase. For example, A and A. If both remain at 1, the light receiving section may be exposed and external light such as fluorescent lamps or sunlight may be entering. Further, if both A1 and Ao continue to be in the O state, there is a possibility that the coupling part 3 and the interface part 6 are coupled upside down and the light does not enter the light receiving part. In order to detect these irregular states, the steps described above are performed.

The sending side device is the receiving side response line A. When it detects that the signal has fallen and then risen again, the transmitting side connects the transmit data bus (
D3 to DO) are the upper 4 bits of the transmission data (D? to D4).
) (c), then lower the transmitting side control line C8 to indicate that the data on the transmitting data bus is valid (
d). On the other hand, the receiving side lowers its own C8 (A on the transmitting side) signal and then sends A indicating data transmission. (C8 on the sending side
) The time (t2) until the signal drops is monitored, and if it takes more than a certain amount of time, it is treated as a communication error. The receiving side receives A within the above time. When the signal on the reception data bus (Qa to QO) falls, the signal on the reception data bus (Qa to QO) is first received as valid information as the upper 4 bits. At this time, the receiver lowers the Co (A on the transmitting side) signal once in a pulse form for a period of t8 and then raises it again to indicate the vote taken. In response to this (e), the sending side releases the information on the sending data bus and C8 from the active state (f, g).

Next, the transmitting side places the lower 4 bits l'' (D3 to D.) of the transmitting data on the transmitting data bus, and sets the transmitting side control line co to O (h).The receiving side receives the data in the same manner as above. The data on the data bus is received as the lower 4 bits, and the data on the own C8 is
Send a pulse to (A on the sending side) (i). Upon receiving this, the transmitting side transmits the transmitting data bus (Da to Do) and 01, c.
Release o from active state (j, k, j')
. This completes one unit of data transmission.

After one unit, ie, 8 bits of data, has been transmitted, it is uncertain which side will become the transmitting side. The one that brings down the transmitting side control line C5 first becomes the next transmitting side. In addition, even if you request the other party to send data, -[
Data representing a transmission request command will be transmitted.

Although the state of the signal is undefined when no valid information is carried on the transmission data bus, power can be saved by forcibly specifying the state in which the infrared light emitting diode 61 does not emit light.

Furthermore, when a sufficiently long time has elapsed compared to the response time t1 or t2 described above, C1 and 00 are also set to zero. As a result, all the light emitting diodes 61, which require a large current to drive, are turned off. This is called a sleeve state. Equipment in sleeve state (portable equipment 4)
0, the expansion operation section 5, and the facsimile machine 1): (1) A key switch is pressed by the operator.

■ Internal stimulation such as a built-in timer (not shown).

■ Signals are input from the interface section.

It will remain in the sleep state unless there is an activation factor such as.

In particular, when activated by a signal from the interface section (2), the control signal lines C1 and co are both 0, so the normal data communication procedure as shown in FIG. 3 cannot be used.

Therefore, in order to request information transmission/reception from the other party's device, a special procedure is required to change the other party's device from the sleeve state to the normal state. An example of the procedure is shown below.

According to the communication procedure shown in FIG. 3, if both C1 and C8 are O, then (1) the other party is not connected and no external light is incident.

■ There is a defect in the physical connection. That is, the coupling part 3 and the interface part 6 are not firmly coupled, or the direction of insertion of the interface part 6 (left/right, top/bottom, etc.) is incorrect.

It was determined that this was the case. However, before doing so, consider the possibility that the other party's device is in a sleeve state, and try applying a pulse to its own control line C8. The pulse application method is
Depending on whether the state of one's own side is a normal state or a sleeve state, the state is divided into either FIG. 6(a) or FIG. 6(b).

FIG. 6(a) is an example when this side is in a normal state.

In this case, the initial states of the transmitting side control lines C1 and C8 on this side are both 1. To change the other party's state to normal, bring down C0 once and then bring it back up. The other party detects this state change and changes its own state from the sleeve state to the normal state. That is, both C8 and C8 are changed to 1. Note that in the normal communication state shown in FIG. 3, C8 never falls when C1 is 1. This side is the receiving side response lines A1 and A. It is determined that the other party has entered the normal state by detecting that both have changed to 1.

FIG. 6(b) is an example where this side is in a sleeve state. In this case, C1 is started up first, and C8 is started up after a while. As a result, this side changes to the normal state. The other party detects this when C1 rises and prepares for a change in C8. And co is from O to 1
When it detects that it has changed to , it changes its state from sleeve state to normal state. This procedure allows the other party to return to normal state.

FIG. 12 shows the facsimile l of this embodiment and the extended operation section 5a.
A block diagram showing the configuration of the system is shown. 9th construction is expansion operation section 5
92 is a memory, 6 is an interface section having a light emitting section and a light receiving section, 45 is a cable, 51 is a keyboard, and 52 is a display.

The processing sequences of FIGS. 3 and 6 are shown in a flowchart in FIG.

[Transmission/Reception Routine] First, the control circuit 91 checks the status of the response line A1 (Sl). If A1 is active (=Low=0), it is determined that there is a request to receive data from the other party, or that the other party is in a sleep state (not connected or not operating even if connected). . In this case,
The control circuit 91 checks the state of Ao (S2).
If is O, it is determined that the opponent is in the sleeve state (S7).

On the other hand, if 80 is not active (=High=1), it is determined that there is a data reception request from the other party, and the reception routine is entered. In addition, if A = 1 in Sl, the other party is in the sleep state (and it is determined that there is no data reception request. At this time, if there is data to be sent from this side to the other party, it is sent. Go to Routine ■.

[Receive routine code] The control circuit 91 sets the command line C0 to 0 (S3).

After that, C0 again after a predetermined time t1°
is set to 1 (S4). This notifies the other party that it is ready for reception. The other party receives this signal change, sets data in D3 to Do (Q3 to QO as seen from this side), and then sets C8 (A as seen from this side) to 1. On the other hand, the control circuit 91 operates for a predetermined time (
A during t2). (S5, S6), and if it does not change to 1 within t2, the other party determines that transmission is impossible (S7)
. When detecting that Ao has become 1, the control circuit 91
Set 8 to 0 (SIO). After that, the data output to Q3 to QO is taken in and stored in the memory 9 as D7 to D4.
2 (SIX). Then, the control circuit 91 sets C0 to 1 to notify the other party that the data has been received.
(S12). The other side receives this and sets Ao to 1. This side is this signal A. change over a certain period of time (t
4) Monitor (513.514). The other side is already fixed A
Set 0 to 0. During this time as well, this side will monitor for a certain period of time (S15.516), and if there is no response, it will be treated as a communication error (2) as in S14.

If there is a response, the control circuit 91 returns Q3 to Q3 as before.
It is determined that Qo contains valid data and sets co to 0 (517), fetches Q3 to Q0 and stores them in the memory 92 as D3 to D0 (518), and sets C0 to 1 again (S
19). The other party receives this and answers A.

Set to 1, and then A. Set to l. This side monitors this state change 2, and if there is no change within a certain period of time, it is determined that there is a communication error (820-523).

When A becomes 1, one data transfer (8 bits) is completed. The control unit 91 combines D7 to D4 and D3 to Do received in process a (Sll) and process b (S18) to create a data set D7 to Ibyte (bytes).
Make Do (828). Then, the subroutine returns with this data (S29).

[Send routine The control circuit 91 first sets C1 to 0 (S31).

Next, check the status of A1 (532), and if it is O, it is assumed that the other party has also issued a transmission request at the same time (533), C1
is set to 1 again and the transmission routine ends. In this case, after an appropriate period of time (determined by random numbers, etc.), the transmission routine is entered again (this routine is not shown).

If A,=1, then A. - Check the state of A during a fixed time t1. = 0, and further t,. If a change to 1 is detected between ($35 to 538),
The control circuit 91 determines that the other party has entered the receiving routine. In other cases, it is determined that the other party is unable to receive data for some reason (539), and the transmission routine is terminated.

If the other party is able to receive the data, the control circuit 91 first reads the transmission data D7 to D4 from the memory 92, and then reads the transmission data D3 to D4.
output to o (S40), and then set C8 to O. The other party receives this and answers A. After making O, the receiver takes D3-D, and A again. Set to 1. This side monitors changes in Ao, and if there is no change within a certain period of time (ts, ts), it determines that normal data transfer was not possible (communication error).
Both co and 01 are set to 1 (846, 547), and the sending routine is exited.

When Ao changes normally, after setting co to 1 (548), D3 to Do are similarly read from the memory 92 and output to D3 to D0 (S49), and co is set to 0 again. Similarly, the other side is A. is set to 0, and the data D3~Do
After receiving A. Set to 1. At this time, this side is A. If there is no change within a certain period of time (t6, to), a communication error is determined (551 to 554).

If normal data transfer is performed, both C8 and C1 are set to 1 (S55.856) and the transmission routine ends. If necessary to save energy, set D3 to Do to 0.
The process (S57) of forcibly stopping the light emission of the LED may also be performed here.

[Communication error during reception] At the time when there was a communication error during reception, the control unit 91 stores data D7 to D0 in the memory 92 (depending on the time when the communication error occurred, the data may not be stored)
is abandoned, an error flag is set (S30), and the process returns.

[Communication error during transmission] If a communication error occurs during transmission, set an error flag and return. Note that if it is determined in S33 that the transmission requests are issued at the same time, the reason is different from other communication errors. Therefore, in this case, providing a separate flag will facilitate subsequent processing.

[Processing when the other party is in the sleeve state] When the control circuit 91 determines that the other party is in the sleeve state (S
7) If there is no data to be sent from this side, there is no need to wake up the other party (S8), so the transmission/reception routine is finished. If there is data to be sent, first it is checked whether this side is in the sleeve state (S60). If it is in the sleeve state, the control circuit 91 first sets C3 to l (S61)
, wait a certain period of time (120) (S62), and set co to 1 (S63). If it is not in the sleeve state, C8 is set to O (564), and C8 is set to l (S65). After setting c to l, wait a certain period of time (tz□) and check the status of A and 80. A,=A.

If = 1, it is determined that the other party is in a state where reception is possible or external light is entering the light receiving section, and the process proceeds to the transmission routine ((S69)
. In other cases, it is determined that the other party is not connected or is in a communication-disabled state, and communication error processing is performed.

In this example, the sending side changes 01 to 1 every time it sends 4 bits of 8-bit data (1 byte), but when sending multiple bytes of data continuously, After that, C1 may be set to 1.

Incidentally, in FIG. 2(a), an inverting amplifier 63 is inserted in the middle of the signal line. Information communicated by infrared radiation requires accuracy, so it is almost always digital.
It's a signal. Therefore, there is almost no loss or garbled signal information, except when external noise is very large or when the cable 45 is so long that attenuation is severe during propagation. Therefore, normally, signal amplification work is hardly necessary when the length of the cable 45 is about 1 to 3 meters. In this example, the intensity of the infrared rays received is low when used under harsh conditions or when received from a portable device that consumes a large amount of power and is trying to save power by minimizing the current flowing through the infrared light emitting diode. An amplifier was inserted in consideration of cases such as LX where the S/N (signal/noise) ratio of the electrical signal is sufficiently low.

FIG. 2(b) shows how information sent and received within the interface section 6 is encoded/decoded.
This is a method of decoding. For example, the second
When six infrared light emitting diodes 61 and six phototransistors 62 are incorporated in the interface section 6 as shown in Figure (a), the power supply (Vcc) and signal ground (GND) are shared, and noise countermeasures are implemented. Even if twisted pair wires were not used, at least 14 signal wires would be required in the cable 45. In reality, it is often necessary to increase the number of electromagnetic shield lines and signal grounds to stabilize the signal, so the number should increase further. The cable, which is made up of 14 signal wires, is quite strong and has a diameter of about 10 mm including the vinyl chloride sheath that binds the entire cable, making it difficult to bend and bulky.

Therefore, the received information is transmitted inside the interface section 6.
- Extremely reduce the number of signal lines in the cable 45 by first encoding the information and passing it through the cable, or by decoding the encoded information coming from the cable into the original signal within the interface unit 6 and transmitting it. is also possible. FIG. 2(b) shows the interface section 45.
This is an example in which full-duplex serial communication according to the R5-232C standard is used for communication between the computer and the extended operation unit 5. In this example, the number of signal lines in the cable is Tx (transmit signal), Rx
There are only four wires: (receiving signal), Vcc (power supply), and GND (signal ground). Compared to the 14 rods in the example above, it is clear that they are much weaker and thinner and easier to handle.

The actual control method between the portable device 40 or the expansion operation section 5 and the facsimile machine 1, that is, the transmission and reception of data and commands for operation, may be performed using a combination of commands and parameters.

This method is used for data transmission between a personal computer and a printer, and for GPIB (GPIB) according to IEEE-488 standard.
General Purpose Interface
Since this is a method used in applications such as eBus, it will not be described in detail here.

Finally, an example of how to use the embodiment shown in FIG. 1 will be shown.

First, the expansion operation section 5 is not used during normal use.

The call operation is performed using the dial keys on the operation unit 2 of the facsimile machine 1, one-touch dial keys, speed dials, etc. if there are any. Furthermore, a person using a portable device 40 such as an electronic telephone directory can set it in the coupling section 3 and use the telephone number stored in the portable device 40 when making a call. .

The full keyboard type extended operation unit 5a is used when registering speed dials and destination names stored in the facsimile machine main body. In this case, the telephone number to be registered, the name of the other party, etc. are first stored in a storage device (not shown) in the extended operation section 5a using the key switch 51, and are displayed on the display section 52 at the same time. At this stage, the input contents have not yet been transferred to the facsimile machine 1.

The operator checks the contents of the display section and, if necessary, corrects the displayed contents using the editing key switch. At this time, by providing a kana-kanji conversion function such as a word processor program used in a personal computer, it is also possible to convert the input content into a mixed kana-kanji expression.

When the operator determines that the correction has been completed and wishes to register the input contents in the facsimile machine 1, the operator presses the transfer key 53. Only then is the input content transferred to the facsimile machine 1 via the interface unit 6. The extended operation section 5a transfers the information stored in the facsimile device 1 to the extended operation section 5a side, and makes corrections in bulk or saves it on a floppy disk or hard disk to prevent unexpected It is also possible to avoid destruction of memory contents due to accidents.

The one-touch dial type extended operation section 5b is used, for example, when the one-touch dial key is not available on the operation section 2 of the facsimile machine, or if there is one, the number of calls is insufficient for the number of calls actually made on a daily basis. One touch key part 5
Similarly to the main body of the facsimile machine 1, each of the terminals 4 is allocated with a storage area sufficient to store a telephone number and an abbreviation of the destination party. This storage area may be located within the expansion operation section 5b or may be located within the facsimile machine l. When the storage area is built into the expansion operation unit 5b, when any one of the one-touch dial keys 54 is pressed, the corresponding telephone number and abbreviated name of the other party (which may not be stored in some cases) are stored in the interface unit 6. The facsimile machine 1 receives this and calls the telephone number. If the storage area is in the facsimile machine 1, the pressed one-touch dial key 5
The switch number No. 4 is transferred, and the facsimile machine 1 expands it into a telephone number and abbreviation of the other party's name, and makes a call. The control keys 55 on the extended operation section 5b are the start key, stop key, resolution switching (fine/standard) key, registration mode setting key, etc. on the operation section 2 of the facsimile device 1. Using these, a simple remote control of the facsimile machine [1] and registration of a telephone number and abbreviated name of the other party to the extended operation section 5b are performed.

Further, using the extended operation section 5a, it is also possible to input a telephone number, abbreviated name of the other party, etc. to be registered in the one-touch dial key 54 of the extended operation section 5b. That is, as shown in FIG. 1O, the communication window 46 on the back side of the interface unit 6 and the six light emitting diodes 61 and phototransistors 62 inside thereof are arranged symmetrically on the transmitting side and the receiving side with respect to the center line. Arrange it so that That is, D3 and Q3, D2
and Q 2 , Dr and Q r , Do and Q, , C, and A1, co and A. corresponds. When placed like this,
When the two interface parts 6, that is, the interface part of the expansion operation part 5a and the interface part of the expansion operation part 5b, are brought into close contact with each other as shown in FIG. become.

As an application of this, information to be registered in the portable device 40 such as an electronic telephone directory may be entered using the extended operation section 5a, or information may be transferred between the portable device 40 and the extended operation section 5b. I can do things.

In other words, a specific one-touch dial of the facsimile 1 or the electronic telephone directory 40 can be changed to the facsimile 1 or the electronic telephone directory 4.
0 or the keyboard of the extended operation section 5a, further input the dial number and name from the cow board 51 of the extended operation section 5a, and after confirming the correct input on the display 52, press the transfer key 53. . Then, the one-touch dial can be input using the easy-to-operate keyboard 51.

FIG. 4 shows an example of an interface circuit in which the data buses (D and Q) of the wireless section are combined into one, and FIG. 5 shows a communication protocol using this circuit. In this case, the pair of infrared light emitting diode 61 and phototransistor 62 is
6 SC(, Co, Qo −, A +, 6 of Ao
Two-way communication is possible in pairs. However, as shown in FIG. 5, the number of communication control procedures increases approximately four times, so the time required for communication becomes approximately four times that of the example shown in FIG. Also, the control line (C
) and response line (A) are still required.

The number of data buses (D and Q) can take any positive integer value such as 2, 8, 16, etc. in addition to 4 each as shown in Figure 3 or 1 each as shown in Figure 8. It is. Generally, the more data buses there are, the faster the data transfer speed will be.
The increase in hardware such as infrared light emitting diodes and phototransistors increases costs and increases the area occupied by optical communication windows.

Therefore, the number of data buses to be used depends on the microprocessor (MICR) that controls the interface circuit.
This is a matter to be determined in consideration of the number of data nodes of the o-processor, the amount of data to be communicated, and the cost of software. In order to transfer approximately 30 digits of numbers (telephone number) and 20 digits of characters (recipient abbreviation) in less than 1 second, the number of data nodes is four or less, which is sufficient in most cases.

Further, the data to be registered in the electronic telephone directory 40 is inputted using the expansion operation section 5a, is temporarily stored in the facsimile device 1, and the interface section 6 is removed to register the data in the electronic telephone directory 40.
is set in the connecting part 3 instead, and the information previously stored in the facsimile device 1 is instructed to be transferred to the electronic telephone directory 40, thereby making it possible to easily input data into the electronic telephone directory 40. become. At this time, after transmitting the information from the facsimile device 1 to the electronic telephone directory 40,
If the information in the facsimile device l is not automatically deleted, the same information can be copied to multiple electronic telephone directories.

By using the above-mentioned method and using 1-ware (for data communication between a portable device and a facsimile machine) and providing an extended operation section outside the facsimile machine,
In normal times, ■ the operating section has a simple configuration without connecting anything to the coupling section 3, ■ the electronic telephone directory 40 is set in the coupling section 3, and the information registered in the electronic telephone directory 40 is displayed. The control panel has a simple speed dial system using An extended operation section 5a is connected to the coupling section 3 to facilitate input work. In addition, if there are many destinations to which facsimiles are sent in the course of daily work, and the number exceeds the number that can be registered in the one-touch dial keys or speed dials inside the facsimile device 1, making it difficult to use, connect the expansion operation section 5b. The number of one-touch dial keys can be increased.

[Other Examples]

In the previous embodiment, a facsimile was described, but the present invention can also be applied to registering a mode in a copying machine or a camera.

Further, in the previous embodiment, an example was described in which communication was performed between the interface section 6 and the coupling section 3 using near infrared rays, but the present invention can also be applied to the case of electrical communication.

〔Effect of the invention〕

As described above in detail based on the embodiments of the present invention,
According to the present invention, it is possible to improve the operability of data input and prevent input errors from occurring. Furthermore, since the data output section is shaped like a memory card, data can be input without providing a new interface for the data output light.
