FIG. 3 is a block diagram showing the relationship with the entire main body 2 of the NC data injection device of this embodiment. In FIG. 3, the same parts as in FIG. 1 are given the same reference numerals.

In FIG. 2, N is the NC data injection device of this embodiment. On the front side, there is a reader 1, a power switch 9, and N (') which can switch between serial transmission and parallel transmission when injecting data into the NC main body 2. The serial/parallel changeover switch 10, the reading operation start switch 11 of the reader l, and the NC data (
The data output activation switch 12 for full injection (serial or parallel), the transmission speed setting switch 13 for setting the entire transmission speed when injecting the NC data into the NC main body (not shown), and the speed setting switch 3 were activated. A numeric keypad 14 for setting all transmission speeds, a speed indicator 5 for displaying the set transmission speed value, a malfunction indicator lamp 16 for displaying malfunctions of this device N, and a connector grab (not shown) of the NC main body are connected. A socket 17 for parallel transmission and a socket 18 for serial transmission are fully equipped.

Next, the functional blocks of the device N will be explained with reference to FIG. This device N is composed of a reader 1 and a device main body 19. The main body 19 of the device is composed of a data processing circuit 20 consisting of a microconverter, etc., the switches 10, 11, 12, 13, a numeric keypad 14, a speed indicator 15, and a malfunction indicator lamp 16. an operation section 21 for giving operation commands to the computer and displaying transmission speed values, malfunction messages, etc.; and the reader 1.
For example, there is a memory circuit 22 that stores all NC data read at 200 characters/second, and the NC data read from this memory circuit 22 is serially transmitted or parallel transmitted (150, 200, 300, 500 characters/second).
It consists of a data conversion circuit 23 that converts the code into code and outputs it to the NC main body 2, and an oscillator 24 consisting of a rate generator etc. that controls the transmission rate (110 to 9600 baud) during serial transmission in this data conversion circuit 23. has been done. In the above, the data processing circuit 20 performs a predetermined operation based on a previously stored operation program based on the operation command of the switches 11, 12, and 13.

Next, the operation of the data injection device N of this embodiment will be explained with reference to FIG. 4, FIG. 2, and FIG. 3. First, in step S1, turn on the power switch 9f! .

When turned on, initial settings such as resetting the transmission speed, clearing the memory circuit 22, and resetting the speed indicator 15 are performed at Stella 7°2. Then, the malfunction indicator lamp 16 is cleared in step S3 via the connector A-i. Next, it is determined whether or not to continue the operation in S4, and the switch 11, 12, or 13 is activated.
"Yes" and proceed to step S5.Here, switch 1
If any one of 1, 12, and 13 is not activated, the result will be "no" and the operating mode will be set at 9 steno fS6. However, if the reading operation activation switch 11 is activated, the mode will be T mode; NC data reading mode. When the data output start switch 12 is started, the mode becomes U mode; NC data output mode. When the transmission speed setting switch 13 is activated, mode (3) becomes transmission speed setting mode. These T and UXV modes are determined in step S5, and operation steps are processed for each mode.

That is, in the T mode, in step T1, a load address is set in the memory circuit 22, and instructions are given to display a message on the reader 1 while a reading operation is being executed. Then, the NC data is read at a predetermined reading speed, for example, 200 characters/second, by the stethoscope T2 via the connector Bi, and if a FOR (end of record) code is not detected at step T5, the data is read according to the above load address at step T4. Store the NC data in the storage circuit 22,
Return to connector B and repeat the above operation. On the other hand, when the FOR code is detected in step T3 above, Stella 7″T
5, sends a reading end message to reader 1, returns to connector A, and ends this T mode operation.

Next, in the U mode, N is stored in the memory circuit 22 in step U1.
It is fully determined whether C data remains or not. If yes, it is determined whether the transmission speed (baud rate in serial transmission) is set in step U2. If yes, the serial parameter is set using Stella 76U. The changeover switch 10 is operated.

Above step U1. If there is no result in U2, an error message is outputted in step U4 and the process returns to connector A. When the switch 10 is operated in step U3,
Step 7''U5 determines whether it is serial mode or parallel mode, and if it is serial mode, step U6
The data rate of the serial transmission speed is set. Then, the presence or absence of a request signal from the NC main body 2 (waiting for a request signal) is determined in step U7 via the connector C1c, and if there is, the NC data is output to the NC main body 2 for each block in step U7. returns to connector C, and if all EOR codes are not detected at step fU8, returns to connector C9. If an EOR code is detected, a message indicating the end of this NC data output mode is output at step U1°. and returns to connector A.

On the other hand, in the case of parallel mode, the timing ktt of 74 parallel transmission is determined in step U, and the presence or absence of a request signal from the NC body 2 (waiting for a request signal) is determined in step U12 after the conclusion 1 Kaneko D-i. If so, the NC data is output block by block to the NC main body 2 in step U15, and if not, the connector D.\\ returns.

If no FOR code is detected in step U14, the process returns to connector A. If an EOR code is detected, a message indicating the end of this NC output mode is output in step U+5, and the process returns to connector A.

Next, in V mode, the speed indicator 15 is cleared in step V, the serial/no-way selector switch 10 is operated in step ■2, and whether serial or parallel is determined by operating the switch 10 is determined in step ■3. If it is serial, the transmission speed of the serial transmission is set in step v4, and the set speed is displayed on the speed setter 15 in step v5.On the other hand, if it is determined that the transmission speed is low in step V, step V6 The transmission speed of Noklarel transmission is set in Step 5, and the above set speed is displayed on the speed display 15.
is displayed, the transmission rate setting mode is ended here, and the process returns to connector A.

The above V mode, that is, the transmission speed setting mode is the step U6. in the U mode. This includes the speed and timing setting operations in U11, and by executing mode (2), the number of steps in mode U can be omitted.
