Although not shown in this figure, the common connector 11 is not overlapped with each pin of each peripheral connector having a different communication system, and the connection switching unit 1
3 has a normal pin directly connected to a corresponding communication interface unit without passing through the corresponding communication interface unit.

The connection switching unit 13 has the same number of common pins 111 and 112 as the number of common pins 111 and 112 of the common connector 11.

That is, for example, as shown in FIG.
When the F section side pin 133a is connected to the GND pin 133e, a "LOW" signal is output to the setting port ENA of the communication interface section 12a with negative logic, and the communication system 12a is set to an enabled state. While I
/ F section side pins 133b to 133d are GND pins 13 respectively.
3e, each pull-up resistor 1
7b to 17d, each communication interface unit 12
"HIGH" is output in negative logic to the setting ports ENB to END of the other communication systems 12b to 12d.
2d is set to a disabled state, and its output line is set to a high impedance state.

Next, the operation of the first embodiment thus configured will be described with reference to the drawings.

First, in the communication processing apparatus configured as described above, the common interface 1
Assuming that a common connector (not shown) of a peripheral device of, for example, the RS-422 specification which is the communication system specification of 2b is connected, the connection switching unit 13 connects the common connector 1 as shown in FIG. From the connection state with the communication interface unit 12a of the H.232C specification, the common connector 1 and the R
The connection is switched to the connection state with the communication interface unit 12b of the S-422 specification.

That is, in the connection switching section 13, the connector side pins 131e, 13e of the changeover switches 131, 132
2e, and the GND pin 13 of the state setting switch 133
3e are connected to the I / F section side pins 131a and 131, respectively.
2a, 133a to I / F section side pins 131b, 132

Then, the communication interface unit 12b

e, 132e, the I / F unit side pins 131b, 132b, and the common pin 1 of the common connector 11 via the communication signal line 15b.
11 and 112, and an enable control signal of negative logic “LOW” is input from the state setting switch 133 to the state setting port ENB of the communication interface unit 12b to be set to the enable state. The signals input through the common pins 111 and 112 of the communication controller 1 are converted according to the communication system.
4 can be sent.

Therefore, according to the first embodiment, the peripheral connectors of a plurality of peripheral devices having different communication systems are mounted on the common connector 11, and the common pins 111 and 112 in the common connector 11 are provided with the plurality of common pins 111 and 112. Because it is shared for connecting the peripheral side connector of the interface of this device, it is possible to support peripheral devices for a plurality of different communication systems without increasing the connector scale, and the overall size of this device can be reduced in size and low cost Becomes possible.

Further, since the plurality of changeover switches 131 and 132 in the connection changeover section 13 are interlocked, the changeover switches 131 and 132 are always switched with the same polarity, so that erroneous operation of the changeover switches 131 and 132 is eliminated and the plurality of changeover switches 131 and 132 are eliminated. Since the changeover switches 131 and 132 and the state setting switch 133 are also interlocked, there is no erroneous operation of the changeover switches 131 and 132 and the state setting switch 133, and only the selected communication interface unit can be enabled, and data collision occurs. Can be avoided, and incorrect data can be prevented from flowing into the internal circuit.

Next, a description will be given of a second embodiment of the communication processing apparatus according to the present invention.

The communication processing apparatus according to the second embodiment has basically the same configuration as the communication processing apparatus according to the first embodiment shown in FIGS. 1 and 2, and is different from the communication processing apparatus according to the first embodiment. ,
Further, the communication interface unit selected by the connection switching unit is notified by lighting of a light emitting diode (hereinafter, referred to as “LED”).

FIG. 3 shows the configuration of a connection switching unit 13 'which is a main part of the second embodiment.

As shown in the figure, the communication processing apparatus of the second embodiment has a state setting switch 13 of a connection switching section 13 '.
3 and the status setting port ENA of each communication interface
An LED is connected to each of the state setting lines 16a to 16d connecting to the END. In FIG. 3, only the LED 20a on the state setting line 16a is shown for convenience.

As shown in the figure, the state setting switch 133 is connected to the GND pin 1
33e and the I / F section side pin 133a, the state setting port E of the communication interface section 12a is connected.
Since NA is grounded to GND via the state setting line 16a and becomes “LOW”, the power supply voltage of the LED 20a + 5V
Current flows to GND via the LED 20a from the
20a will light up.

Therefore, according to the second embodiment, the connection switching section 13 'causes the common pin 11
Since it is possible to know which communication interface unit 1, 112 is connected to each of the LEDs on the state setting lines 16a to 16d, the switching result of the communication interface unit can be visually confirmed, and the connection can be further improved. The switching operation of the switching unit 13a 'is not mistaken.

For this reason, especially when the connection switching unit 13 'is mounted at a place where it cannot be visually checked, the currently used communication interface unit is visually checked by lighting the LEDs on the state setting lines 16a to 16d. Can be effective in such a case.

Next, a description will be given of a third embodiment of the communication processing apparatus according to the present invention.

And a normal pin directly connected to the corresponding communication interface unit without passing through the connection switching unit 23.

The connection switching section 23 is composed of two interlocking switch groups 23a, 23

The OR circuit 23d and the pull-up resistors 23g and 23h function as communication state setting means of the communication interface unit 22b.

The interlocking switch groups 23a, 23b are respectively provided with changeover switches 231a, 232a, 2 provided corresponding to the common pins 111 to 114 of the common connector 11.
31b, 232b and each communication interface unit 22a,
State setting switch 233 for setting the operation state of 22b
a, 233b.

In the interlocking switch group 23a, the changeover switches 231a and 232a and the state setting switch 23
3a in conjunction with each other, and in the interlock switch group 23b, the changeover switches 231b and 232b and the state setting switch 233b
Are configured to work together.

The changeover switches 231a, 232
The connection between a, 231b and 232b and the common pins 111 to 114, and the connection between the communication interface units 22a and 22b are the same as those in the first and second embodiments.

Each state setting switch 233a, 233
3b is a GND grounded on the connector side, respectively.
In addition to the pins 233a1 and 233b1, the communication interface units 22a and 22a
2b connected to the status setting ports ENA and ENB
F section side pins 233a2, 233a3, 233b2, 23
3b3.

The input side of the OR circuit 23c is connected to the I / F section side pins 233a2 and 233b2 of the state setting switches 233a and 233b through signal lines to which the pull-up resistors 23e and 23g are connected. Its output side is a state setting port EN of the communication interface unit 22a via a state setting line 26a to which the LED 30a is connected.
A is connected.

Similarly, the input side of the OR circuit 23d is connected to the input terminals of the state setting switches 233a and 233b via signal lines to which the pull-up resistors 23f and 23h are connected.
The output side is connected to the state setting port ENB of the communication interface section 22b via the state setting line 26b to which the LED 30b is connected, while being connected to the / F section side pins 233a3 and 233b3.

Next, the operation of the communication processing apparatus according to the third embodiment thus configured will be described mainly with reference to FIG.

First, the state setting switches 233a and 233b of the interlocking switch groups 23a and 23b set the connection destinations of the GND pins 233a1 and 233b1 to the I / F section side pins 233a2 and 233b2 as shown in FIG. Will be described from the case where

In this case, the I / F section side pins 233a2, 233a
33b2 is connected to GND, so that a "LOW" signal is input to both inputs of the OR circuit 23c,
While the "LOW" signal is output from the output side of the circuit 23c, the I / F section side pins 233a3 and 233b3 are not connected to GND, so the two inputs of the OR circuit 23d are pulled up on the signal lines 23j and 23m. Resistance 23f, 23h
As a result, the "HIGH" signal is input together, and the "HIGH" signal is output from the output side of the OR circuit 23d.

For this reason, the state setting port ENA of the communication interface unit 22a is connected to the output side of the OR circuit 23c through the state setting line 26a to connect to the negative logic "L".
OW "signal is input and LE on the state setting line 26a is
D30a lights up, while the communication interface unit 22b
Is input to the state setting port ENB via the state setting line 26b connected to the output side of the OR circuit 23d, and the LED 30b on the state setting line 26b is turned off. .

Therefore, in this case, when the LED 30a is turned on, it indicates that the switching polarities of the interlocking switch groups 23a and 23b match, and the LED 3a is turned on.
By turning on 0a and turning off the LED 30b, the connection by the interlocking switch groups 23a and 23b is switched to the communication interface unit 22a side, that is, the communication interface unit 22a is set to the enable state, and the communication interface unit 22b Is set to the disabled state.

The state setting switches 233a, 233
b, the connection destinations of the GND pins 233a1 and 233b1 are the I / F section side pins 233a3 and 233b3, respectively, and the switching polarity of the state setting switches 233a and 233b is the same, so that the same as the above case. Then L
The interlocking switch groups 23a and 23b are activated by the lighting of the ED 30b.
LED indicates that the switching polarity of
When the LED 30b is turned off and the LED 30b is turned on, the communication interface unit 22a is set to the disabled state, indicating that the communication interface unit 22b is set to the enabled state.

Next, the state setting switches 233a, 233
The case where the switching polarities of b do not match, that is, the case where the switching polarities of the interlocking switch groups 23a and 23b do not match and the switching is erroneous will be described.

First, for example, in the state setting switch 233a on the interlocking switch group 23a side, as shown in FIG.
While the D pin 233a1 is connected to the I / F section side pin 233a2, the state setting switch 233b of the interlocking switch group 23b is different from the case shown in FIG.
It is assumed that 33b1 is connected to the I / F section side pin 233b3.

In this case, "LOW" is applied to the two inputs of the OR circuit 23c by GND ground via the signal line 23i.
A signal is input, and a “HIGH” signal is input via a pull-up resistor 23g via a signal line 23k. An “HIGH” signal is input to the input side of the OR circuit 23d via a pull-up resistor 23f via a signal line 23j. While typing
A “LOW” signal is input by GND ground via the signal line 23m.

As a result, the output side of the OR circuits 23c and 23d both output a "HIGH" signal.
The status setting ports ENA and ENB of the communication interface units 22a and 22b are connected via the status setting lines 26a and 26b.
And a negative logic “HIGH” signal is input to both
LEDs 30a, 30 on state setting lines 26a, 26b
Both b are turned off.

Accordingly, in this case, the LEDs 30a, 3
0b are both turned off and not turned on, so that the switching polarities of the interlocking switch groups 23a and 23b do not match, that is, the switching operation of the interlocking switch groups 23a and 23b is erroneous, and the communication interface units 22a and 22b are both turned off. Indicates that it has been set to the disabled state,
Both communication interface units 22a and 22b are both set to the disabled state.

The state setting switch 233a of the interlocking switch group 23a sets the connection destination of the GND pin 233a1 to I.
/ F section side pin 233a3 and the interlocking switch group 2
The state setting switch 233b on the 3b side sets the GND pin 233
When the connection destination of b1 is the I / F side pin 233b2, the state setting switches 233a, 233a,
Since the switching polarities of 233b do not match, similarly to the above case, the LEDs 30a and 30b are turned off, the switching operation of the interlocking switch groups 23a and 23b is erroneous, and both the communication interface units 22a and 22b are disabled. This indicates that the setting has been made.

Therefore, according to the third embodiment, similar to the first and second embodiments, the common connector 11
Are used for connecting connectors of peripheral devices of different communication systems, so that the connector scale does not increase, the peripheral devices can be used for a plurality of different communication systems, and the overall size of the device can be reduced. , Lower cost is possible.

Further, in the third embodiment, the interlocking switch group 23
a and 23b, there is usually a physical limit to the number of interlocking switches incorporated in one switch, and there are not so many, usually two or three switches. This is very effective when the number of 11 common pins is larger.

Further, in the third embodiment, each of the interlocking switch groups 23a, 23b is
b changeover switches 231a, 232a, 231b,
State setting switches 233a, 233 interlocked with 232b
b, and the state setting switches 233a, 233
If the switching polarities of b correspond, an enable signal is sent to the operation setting port of one of the newly connected communication interfaces, and the L level of the communication interface is changed.
The ED is turned on, a disable signal is sent to the operation setting port of the other communication interface unit, and the LED of the other communication interface unit is turned off, while the switching polarity of the state setting switches 233a and 233b is changed. If they do not match, each communication interface unit 22a,
A disable signal is sent to the operation setting ports ENA and ENB of the communication interface units 22a and 22b.
Since the 2b LEDs 30a and 30b are turned off, each of the interlocking switch groups 23 in the connection switching unit 23
If the switching operations of the switches a and 23b are erroneous, the communication interface sections 22a and 22b do not operate in the disabled state, so that data collision and erroneous data flowing into the internal circuit can be prevented. Switch group 2
3a and 23b are switched by the LEDs 20a and 20b.
It can be visually confirmed by turning on and off of b,
Each interlocking switch group 23a in the connection switching unit 23,
The switching operation of the switch 23b is not mistaken.

Therefore, the third embodiment is very effective, similarly to the case of the second embodiment, particularly when the connection switching unit 23 is mounted in a place where it cannot be visually confirmed.

In the third embodiment, the communication system of the peripheral device connected to the common connector of this device is RS-2.
32C and RS-422, the communication interface units 22a and 22b and each changeover switch and the state setting switch have been described as having two switching polarities. However, in the present invention, the communication method is of course two or more types. Also in this case, similarly to the case of the third embodiment, an LED is provided for each communication interface unit, and the switching polarity of each changeover switch and the state setting switch is set to the number of types of the communication system. If configured, the third
The same effect as that of the embodiment can be obtained.

[0072]

As described above, according to the present invention, the peripheral connectors of a plurality of peripheral devices having different communication systems are mounted on one common connector, and the common pins in the common connector have different communication systems. Since it is commonly used for connecting the peripheral side connector, it is possible to correspond to peripheral devices of different communication systems without increasing the connector scale, and it is possible to reduce the size of the entire device and to reduce the cost. .

Further, since the plurality of changeover switches in the connection changeover section are interlocked, the changeover switches are always switched with the same polarity, thereby preventing erroneous operation of the changeover switches, and the plurality of changeover switches and the state setting switch are also interlocked. This eliminates erroneous operation with the changeover switch. Therefore, only the selected communication interface unit can be set to the enabled state, so that data collision can be avoided and erroneous data can be prevented from flowing into the internal circuit.

Further, the communication switching unit notifies the communication interface unit to which the common pin of the common connector has been connected by the notification unit, so that the switching result of the communication interface unit can be visually confirmed, and The switching operation of the switching unit will not be erroneously performed. In particular, when the notification unit is a light emitting diode (LED), it is very effective when the connection switching unit is mounted in a place where it cannot be visually confirmed.

Further, since the connection switching unit is configured as an interlocking switch group for each interlocking switching switch, the number of interlocking switching switches incorporated in one switch is physically limited, and is not so large. , 3 are common, and this is effective when the number of common pins of the common connector 11 is larger than this number.

Further, a state setting switch is provided for each of the interlocking switch groups in conjunction with the changeover switch of each interlocking switch group, and when the switching polarities of the state setting switches match, only the newly connected communication interface is enabled. When the switching polarity of the status setting switch does not match, each communication interface unit is set to the disabled state, while the other communication interface units are set to the disabled state. When the switching operation of each interlocking switch group in the switching unit is erroneously performed, each communication interface unit does not operate in the disabled state, thereby preventing data collision and erroneous data flowing into the internal circuit.
