Description

The present invention relates to control of a paper tape reading terminal device, and more particularly to a paper tape reading terminal control device for controlling the paper tape reading terminal device.

(Prior Art) Conventionally, when reading a punched paper tape from a paper tape reading terminal device, an operator first types in a paper tape reading request from the typewriter section of the paper tape reading terminal device, and then the paper tape reading terminal device The paper tape running start button was pressed to run the paper tape, and the data punched on the paper tape was read.

(Problems to be Solved by the Invention) In the conventional paper tape reading terminal control device described above, after the paper tape reading request is typed in, the paper tape is made to travel by button operation and the data punched in the paper tape is read. As a result, the paper tape running button has to be pressed every time the paper tape is read.

In addition, some paper tape reading terminal devices do not punch data on the paper tape but transfer "feed code" only for the feed, and the central processing unit collects all the data received through the paper tape terminal control device. If the searched and received data is a "feed code", there is a drawback that a program process is required to extract and delete the data and re-edit the received data.

An object of the present invention is to send a paper tape running start code to a paper tape reading terminal device if the command received from the central processing unit is a paper tape reading command, and to send a paper tape running start code to the paper tape reading terminal device if the received data is a specific code. A paper tape reading terminal control device configured to eliminate the above-mentioned drawbacks by sending a paper tape running stop code to the central processing unit and transferring the data received up to that point to a central processing unit so that it is not necessary to perform a button operation. To provide.

(Means for Solving Problems) A paper tape reading terminal control device according to the present invention reads data from a paper tape of the paper tape reading terminal device and controls the read data to be sent to a central processing unit through a channel device. In the reading terminal control device, a memory unit for storing a microprogram and data, a pair of interface units respectively connected to the channel device and the paper tape reading terminal device, and a memory unit and a pair of interface units If the command received from the central processing unit is a paper tape reading command, a paper tape running start code is sent to the paper tape reading terminal device, data is sent from the paper tape reading terminal device, and the sent data is a feed code. If you have this feedco Code is ignored, data other than the feed code is stored in the memory section, and if the data is a specific code, a paper tape running stop code is sent to the paper tape reading terminal device and stored in the memory section. And a control unit for transferring data including the specific code to the central processing unit, and when the specific code sent from the central processing unit is a code indicating that there is data to be transferred, the paper tape A paper tape read command is sent to the reading terminal control device, and when the specific code sent is a code indicating that all the data has been read, the data reading process is ended.

(Example) Next, this invention is demonstrated with reference to drawings.

FIG. 1 is a block diagram showing an embodiment of a paper tape reading terminal control device according to the present invention together with related devices. In FIG. 1, 10 is a central processing unit, 20 is a channel device,
30 is a paper tape reading terminal control unit, 31 is a channel interface unit, 32 is a control unit, 33 is a memory unit, 34 is an input / output interface unit, 40 is a paper tape reading terminal unit, 41
Is a typewriter unit, and 42 is a paper tape reading unit.

The paper tape reading terminal control device 30 controls the paper tape reading terminal device 40 by a command from the central processing unit 10, receives and stores the data sent from the paper tape reading terminal device 40, and transfers the data to the central processing unit 10.

FIG. 2 shows a paper tape reading terminal control device 30 according to the present invention.
2 is a flow chart showing the control operation of.

FIG. 3 is an explanatory view showing a paper tape on which data is punched according to the present invention.

Next, the operation of the paper tape reading control device 30 according to the present invention will be described with reference to FIGS.

When reading a punched paper tape as shown in FIG. 3 from the paper tape reading terminal device 40, the operator sets the paper tape in the paper tape reading portion 42 of the paper tape reading terminal device 40 and types the paper tape reading request from the typewriter portion 41. In. When the central processing unit 10 receives the paper tape reading request through the paper tape reading terminal control device 30, it sends a paper tape reading command to the paper tape reading terminal control device 30. Upon receiving the command from the central processing unit 10, the paper tape reading terminal control device 30 analyzes whether or not the above command is a paper tape reading command, and if it is a paper tape reading command, it is sent to the paper tape reading terminal device 40 through the input / output interface unit 34. In response, a paper tape running start code is sent.

Upon receiving the paper tape running start code, the paper tape reading terminal device 40 activates the paper tape reading unit 42 to start running the paper tape, and sends the data read by the paper tape reading unit 42 to the paper tape reading terminal control device 30.

When the paper tape reading terminal control device 30 sends the paper tape running start code, the paper tape reading terminal device 40
To wait for data to be received from. Therefore, when the data is received, it is determined whether or not the received data is a "feed code", and if the received data is a "feed code", the above reception is ignored and the next data reception waiting state is returned. If is other than "feed code", the paper tape reading terminal control device 30 stores the received data in the memory section 33. The paper tape reading terminal control device 30 receives the specific code of ";" or "!" Otherwise, it returns to the state of waiting for reception of the next data.

When the received data is the specific code of ";" or "!", The paper tape running stop code is sent to the paper tape reading terminal device 40, and all the received data accumulated so far is transferred to the central processing unit 10. . If the code at the end of the transferred paper tape read data is the ";" code, the central processing unit 10 determines that there is still data to be transferred on the paper tape, and again asks the paper tape read terminal control device 30. Command to read the next data block punched on the paper tape according to the same procedure.

If the code at the end of the transferred paper tape read data is "!", The central processing unit 10 determines that all the data punched on the paper tape has been read, and finishes the data reading process from the paper tape. To do.

As a result, the central processing unit 10 reads all data except the "feed code" punched on the paper tape as shown in FIG.

As described above, according to the present invention, when the paper tape read command from the central processing unit is received, the paper tape running start code is sent to the paper tape reading terminal, and the paper tape read data received from the paper tape reading terminal device. If is a specific code, the paper tape running stop code is sent to easily and reliably control the running start / stop operation of the paper tape set in the paper tape reading terminal device.
There is an effect that the operator can automatically read the data punched on the paper tape without pressing the running start button of the paper tape reading terminal device.

Further, it is not necessary to delete the "feed code" in the central processing unit by deleting the "feed code" from the paper tape read data including the "feed code" sent from the paper tape terminal device and transferring it to the central processing unit. Therefore, there is an effect that the load on the central processing unit can be reduced.
