Detailed Description of the Invention

[0001]

[Industrial application] A card-type package with a built-in electronic unit, a plurality of slots that are provided to allow the insertion of the package, and are given different slot addresses. When the socket is connected to a socket attached to one edge of the package, an address bus and a data bus connected to the socket of each slot, and an address bus and a data bus connected to each slot, The present invention relates to a package-mounted data processing device having a control device that recognizes a mounting state in a slot, appropriately controls a package inserted in the slot, and performs desired data processing.

[0002]

2. Description of the Related Art In a package-mounting type data processing device which is an electronic device having a plurality of slots, and a package having a desired function is inserted and mounted in the slots to operate, a package mounted type data processing device has It is necessary to manage the type of implemented package. One of the methods for managing the package mounting state of this type of electronic device is disclosed in Japanese Patent Application No. 62-312526.

FIG. 8 is a block diagram showing the structure of a package-mounted data processing device according to the prior art. In this device, the control device 510, the address lines and data lines connected to the control device 510, the slots # 1 to # 3 to which the slot address line for giving a unique slot address to each slot is connected, and each slot. It consists of packages A and B that are mounted.

The operation of the conventional package-mounted data processing device will be described with reference to FIG. Since the control device 510 recognizes which package is mounted in which slot, each package is polled. The controller 510 periodically outputs the address of each slot to the address line, and reads the package type from the data line. That is, the control device 510 periodically outputs addresses “1”, “2”, and “3”, and in the package, when the slot address and the address output by the control device 510 match, the package type is output. In the example of FIG. 8, the control device 510
When the address 1 outputs the address 1, the package A outputs “A” as the package type, and when the address 2 outputs, the package B outputs “B” as the package type. If the package is not installed, no response will be returned. As a result, the control device 510 can recognize what is installed in which slot.

[0005]

In the conventional package-mounted data processing device described above, the mounting state of the package in each slot can be recognized by polling from the control device. However, when the package mounting state changes, the mounting state change can be detected only at the polling interval.

On the other hand, when the duplication is performed for each package (for example, when the same package is inserted like slots # 2 and # 3 in FIG. 8 and the duplication operation is performed), one package is used. It is necessary to substitute the function of that package by the other package because of the omission. In this case, it is necessary to detect the change in the mounting state in a short time in order to shorten the failure time. In this case, in order to speed up the detection of the change in the mounting state, there is a problem that the polling cycle must be shortened, and thus the capability of the control device must be increased.

In view of the above problems, the present invention provides a package mounting type data processing device which can change the mounting state of a package in a slot in a short time without increasing the capability of a control device. With the goal.

Embodiments of the present invention will now be described with reference to the drawings. 1 is a block diagram showing a first embodiment of a package mounting type data processing device of the present invention, FIG. 2 is a block diagram showing a package insertion / extraction signal generating device mounted in a package of the embodiment of FIG. 1, and FIG. The figure which shows the package inserted in the slot provided in the case, FIG.
FIG. 5B is a diagram for explaining the operation of the package inserted into the rail forming the slot, and FIG. 5 is a sequence diagram showing the operation of inserting / removing the package into / from the slot.
In the present embodiment, there will be described a case where there are three slots in which the packages are mounted and there are two types of packages, A and B, which can be mounted in the slots. Of course, the present invention is not limited to the number of slots and the number of types of packages of this embodiment.

As shown in FIG. 3, the slots # 1, # 2, and # 3 are provided inside the bottom and top surfaces of the case 70 whose front surface is open. The pair of rails 71 and 72 are opposed to each other.
And a socket 73 disposed inside the rear surface corresponding to each slot. Each socket 73 is provided with an address terminal, a data terminal, and an interrupt signal terminal. 1, an address bus 30, a data bus 40, interrupt lines 51,
It is connected to the control device 110 via 52 and 53. The socket 73 is also provided with a slot address terminal to which a slot address is given.

Each package A, B is provided with a plug 13, and the plug 13 is provided with an address terminal, a data terminal, an interrupt signal terminal and a slot address terminal, and these terminals are provided in each package. When A and B are inserted into the slots, the plugs 13 are inserted into the sockets 73 of the slots, respectively.
3 address bus terminals, data terminals, interrupt signal terminals, and slot address terminals. The packages A and B have different functions and the plug terminals are formed in the same shape, so that they can be inserted into any of the slots # 1, # 2, and # 3.

As shown in FIG. 2, when the package is inserted into the slot, the insertion / removal signal processing device mounted in each package has slot addresses preset in the slots # 1, # 2, and # 3. (In this embodiment, each of the slots # 1, 22, 23 has an address 1,
2 and 3) is input through the slot address terminal, and the address given from the control device 110 is input through the address bus 30. When the circuit detects that the two addresses match, the package identifier (A or B) indicating the type of the inserted package
Identifier generating circuit 22 for outputting the
0 and an interrupt switch 230 that generates an interrupt signal at the start of insertion.

Next, the operation of the embodiment shown in FIG. 1 will be sequentially described with reference to FIGS. First, the case where the package A is inserted into the slot # 1 will be described. Rotate the eject levers 11 and 12 mounted on the package A in the directions of the arrows X and Y about the mounting shaft, respectively, and
Insertion into slot # 1 is started along 1, 72. The interrupt switch 230 is turned on with the rotation of the eject lever 11 because the tip of the actuator is fitted in the notch 11a of the eject lever 11. When the insertion of the package A further progresses, the insertion of the plug 13 into the socket 73 and the connection between the terminals occur, a low level (ground level) interrupt signal is output to the interrupt line 51 from the interrupt switch 230 in the ON state. (S1).

When the interrupt signal is output to the interrupt line 51, the controller 110 recognizes that an interrupt has been issued from slot # 1. As a result, the controller 110
Recognizes that the mounting state of the slot # 1 has changed (S2), and outputs the address 1 for the slot # 1 to the address bus 30 (S3) to confirm what has changed (ID confirmation). Package A in slot # 1
Compares the address output to the address bus 30 with the slot address. When the slot address and the address from the address bus match, the fact is notified to the package identifier generating circuit 220, and the package identifier generating circuit 220 outputs the package identifier, which is a unique name of the package, to the data bus 40 (S4). In this case, since the values of both addresses match with each other, "A" is output as the package identifier. The controller 110 reads the value “A” on the data bus 40 and recognizes that the package A is mounted in the slot # 1 (S
5).

On the other hand, the notches 11b and 12b of the eject levers 11 and 12 are bent ends 71 of the rails 71 and 72.
When it is pressed in the directions of the arrows P and Q at the time of facing the a and 72a, the notches 11b and 12b engage with the bending terminals 71a and 72a of the rails 71 and 72, and a pressing force is applied to the package A, so that the package A is pressed. The plug 13 is completely inserted into the slot # 1, the plug 13 and the socket 73 are completely coupled, and the tip of the actuator of the interrupt switch 230 is made free in the notch 11a to turn off the interrupt signal.

When removing the package A from the slot # 1, it is the reverse of the insertion, and the eject levers 11 and 12 of the package A in the state of FIG. 4B are moved in the directions opposite to the arrows P and Q. When pulling and pulling out are started (S6), before the package A is completely pulled out, the interrupt switch 230 is first turned on to send an interrupt signal to the interrupt line 5.
Output to 1. The control device 110 detects that an interrupt signal has been sent from the interrupt line 51, and recognizes that an interrupt has been issued from slot # 1. Therefore, the control device 110 recognizes that the mounting state of the slot # 1 has changed, and outputs the address 1 of the slot # 1 to the address bus 30 in order to confirm what has changed (S
7). Since the package A has already been removed from the slot # 1 during this time, there is no response from the package to the address 1 output by the control device 110. As a result, the control device 110 recognizes that the package A has been removed from the slot # 1 (S8). Through the above operation, the control device 110 constantly polls slot # 1,
It is possible to detect the insertion and removal of the packages A and B at high speed without monitoring the states of # 2 and # 3.

Next, a second embodiment of the present invention will be described with reference to FIGS. 6 and 7. Also in this embodiment, the number of slots in which the package is mounted is 3, and slots # 1 and #
It is assumed that there are two types of packages A and B to be mounted on Nos. 2 and # 3. In this embodiment, the control device 310, the address bus, the data bus, and the interrupt line connection terminal are the control device 3.
Slot # 1, # 2, and # 3 connected to the bus 10 by bus and output the value corresponding to the slot number, and the address terminals, data terminals, and interrupts corresponding to the connection terminals of the slots. It has a terminal and a slot address terminal.

Further, each package is provided with an insertion / removal signal processing device similar to the insertion / removal signal processing device (FIG. 2) provided in the embodiment of FIG. That is, a comparison circuit 210 whose two input terminals are connected to the address terminal and the slot address terminal of the package, and a package identifier whose input terminal is connected to the output terminal of the comparison circuit 210 and whose output terminal is connected to the data terminal of the package. Generation circuit 220
And an interrupt switch 230 for dropping the interrupt terminal of the package to the ground level.

A case where the package A is mounted in the slot # 1 will be described. The interrupt switch 230 mounted on the package is interlocked with an ejector lever that is operated when inserting or removing the package, and remains in the ON state until the package is completely inserted. That is, after the terminals of the package are connected to the terminals of the slot, the interrupt switch 230 remains in the ON state until the ejector lever is pushed into the position where the package is completely inserted. Therefore, when the package A is inserted into the slot # 1, the interrupt terminal is at the ground level and interrupts the control device 110 from the time when the terminal of the package contacts the terminal of the slot to the time when the package is completely inserted. (S11).

When an interrupt occurs, the control device 110 recognizes that the mounting state of any slot has changed, sequentially outputs the addresses corresponding to each slot, and waits for a response to each (S12). In this embodiment, since the package is inserted in the slot # 1, the control device 3
When 10 outputs the address 1, the package A outputs "A" as data as in the first embodiment (S1).
3). In order to confirm in which slot the change has occurred, the control device 310 holds the state before the interrupt is applied and compares it with the response after the interrupt is generated (S1).
4). In this embodiment, the slot was empty before the slot # 1, but since "A" could be read as the package type this time, it is recognized that the package A is mounted in the slot # 1 (S15).

When the package A in the slot # 1 is removed, the interrupt switch 230 is turned on and an interrupt signal is generated before the package is completely removed in accordance with the operation of the ejector lever (S16). Control device 1
When an interrupt occurs at 10, it is recognized that the mounting state of any slot has changed, and the addresses corresponding to each slot are sequentially output, and a response to each is waited (1
6). In this embodiment, since the package in slot # 1 has been removed, the address 1 output by the controller 310 is
There is no corresponding package for the controller, and the controller has slot # 1
It is recognized that the package has been removed from (S17). In this embodiment, since the interrupt signal is bus-connected to the control device 310, there is an advantage that the control device 310 can accept a small number of interrupt lines. Therefore, it is suitable for a device having a large number of slots.

[0028]

As described above, the interrupt signal is generated from the package to be mounted in the control device immediately after it is inserted into the control device, and immediately before it is removed from the control device. The effect is to be able to recognize the change, i.e. whether the package is inserted in the slot and what kind of package is inserted.
