FIG. 4 is a flow chart showing an example of the control processing procedure of the CPU 21 at the time of recording by the ink jet printer apparatus of this embodiment. The control program for executing this processing procedure is stored in advance in the program memory 24 of FIG. ing. At the start of this process, it is assumed that the data from the host computer 14 has been received and already stored in the reception buffer area of the data memory 23.

First, after expanding the data stored in the reception buffer of the data memory 23 to the print buffer of the working memory 25, the CPU 21 causes the carriage 6 to operate.
The scanning is started in the forward direction (PT direction in FIG. 1) to start the recording operation (step S300). Then step S
In step 301, the CPU 21 moves the carriage 6 in the PT direction. In order to drive the carriage 6 in the normal direction from the output port 26 via the driver 27, the carriage motor stored in the carriage memory 111 of the nonvolatile memory 100. Read the phase excitation data of 7 (see Fig. 6),
The carriage motor 7 is rotationally driven according to this phase excitation data.

FIG. 6 is a diagram for explaining a phase excitation signal of the carriage motor 7, and here shows phase excitation data when the carriage motor 7 is rotationally driven by two-phase excitation. In Fig. 6, the carriage address (CR Ad
The contents of addresses 0 (Adr0) to (Adr3) indicated by r) are sequentially read and output for each step.

Next, in step S302, the drive circuit 29 outputs the print data to be output to each head 9 of the print head 90.
Set to. After setting the print data, the process proceeds to step S303, and a pulse signal having a predetermined pulse width is applied to each head 9 of the print head 90. The pulse signal width at this time is defined by the time t1 measured by hardware or software. When the measurement of the time t1 ends, the energization of each head 9 of the recording head 90 is stopped (step 304, S305). At the same time, in step S305, the content of the position counter 113 (see FIG. 8) provided in the non-volatile memory 100 is incremented by 1 each time the power is supplied. Based on the value of the position counter 113 (position address), it is determined in step S306 whether recording is completed. If the value of the position counter 113 does not exceed the value indicating the amount of one scan (specified number of recording dots) in step S306, step S301.
Then, the operation of steps S301 to S306 described above is repeated.

Next, in step S306, when it is determined that the value of the position counter 113 exceeds the predetermined number of recording dots (recording for one scan is completed), the process proceeds to step S308, and the CPU 21 records in the backward direction (see FIG. 1 recording in the CR direction) is started. Next, in Step S308, the CP
U21 drives the carriage motor 7 in the reverse direction from the output port 26 via the driver 27 so that the nonvolatile memory 1
The contents in the directions Adr3 to Adr0 indicated by the address (Adr) in FIG. 6 stored in the carriage memory 111 of No. 00 are read out and output for each step. This allows
The carriage motor 7 reversely rotates and the carriage 6 moves toward the home position. Next, in step S309, the print data is set in each head 9 of the print head 90 in the drive circuit 29, and then the print head 9 is set in step S310.
A signal having a predetermined pulse width is applied to each head 9 of 0. The pulse width at this time is the time t1 defined by hardware or software as in the above. When this time t1 elapses, the process proceeds to step S311, and the energization of each head 9 of the recording head 90 is stopped. At this time, in step S312, the content of the position counter 113 (FIG. 8) provided in the non-volatile memory 100 is decremented by 1 each time the power is supplied.

In step S313, it is determined whether or not the printing operation in the backward direction is completed based on the value of the position counter 113, and in step S313, the position counter 113 determines the specified number of print dots in one scan. If not exceeded, the process returns to step S308, and the above-described operations of steps S308 to S313 are repeated. When it is determined in step S313 that the value of the position counter 113 exceeds the predetermined number of recording dots, the process proceeds to step S315, the sheet feeding motor 4 is rotationally driven, and the reciprocal recording is completed. In this step S315,
In order to prepare for the recording of the next row, the sheet feeding motor 4 is rotationally driven from the output port 26 through the driver 27,
The address (L Adr) of the sheet feed address (LF Adr) stored in the sheet feed memory 112 of the nonvolatile memory 100
Address 3 (Adr3) to (Ad
The contents of each address (see FIG. 7) are read out in the r0) direction and rotationally driven. In this way, the sheet feeding motor 4 is rotationally driven by the two-phase excitation by the predetermined number of steps, and the recording medium 1 is conveyed in the A direction. In this way, the recording medium 1 is conveyed by one line in the direction A shown in FIG. 1 according to the recording width, and the memory check data “AAH” (H
Represents a hexadecimal number). In addition, this data "AA
The use of "H" will be described later.

Next, FIG. 5 is a flow chart showing an example of the processing procedure of the CPU 21 in the initial state of the ink jet printer of this embodiment. It is assumed that this processing procedure is stored in the program memory 24 of FIG. 3 in advance.

The CPU 21 determines whether valid data is written in the check area 114 of the non-volatile memory 100 (S401). This is because the non-volatile memory 100 is in the initial state, that is, nothing is written,
Alternatively, this is to detect the presence / absence of a read / write failure in the nonvolatile memory 100.

In the present embodiment, when the data "AAH" in which the bits "1" and "0" are alternately arranged at a predetermined address of the check area 114 of the non-volatile memory 100 is detected, the non-volatile memory 100 becomes past. Is determined to have been accessed. In addition, while a data is being written to an address in the check area 114 of the non-volatile memory 100, if a situation such as the main power supply of the printer device being turned off occurs, the data write guarantee cannot be ensured, and noise and other The data is written to a plurality of addresses in the check area 114 of the non-volatile memory 100 in consideration of the failure.

In step S401, the nonvolatile memory 100
The data read from the check area 114 of the
If it is determined that it is not “H”, the nonvolatile memory 10
It is conceivable that the content of 0 is in the initial state, that is, nothing is written, or that a failure has occurred during writing to the nonvolatile memory 100. In this case, the nonvolatile memory 1
00, the phase excitation information of the position counter 113 and various motors cannot be trusted, so the process proceeds to step S402. In step S402, the CPU 21 reads the initial excitation data stored in advance in the program memory 24 and sends it to the output port 26 to correct the value of the position counter 113 of the carriage 6 in which the current position may be incorrect. First, the carriage 6 is moved in the PT direction. In this case, the phase excitation data of the carriage motor 7 is output from the output port 26 via the driver 27, and the normal rotation drive is performed for n steps in a cycle longer than the rotation cycle during recording. The lengthening of the excitation period in this way means that the carriage motor (stepping motor) 7 for moving the carriage 6 is, for example, B, / A (/ A indicates that a reverse current flows in the A phase). If it was excited by and stopped,
When the excitation data for exciting A and / B is output, the carriage motor 7 is not always guaranteed to rotate normally. Therefore, the excitation period (excitation pulse width) is lengthened so that the motor 7 rotates reliably.

Next, in step S403, the CPU 21
In order to move the carriage 6 in the CR direction, the carriage motor 7 is reversely driven from the output port 26 via the driver 27 at a cycle longer than the excitation cycle during recording. At this time, the position detection signal input from the home position sensor 30 via the input port 31 is transmitted to the carriage motor 7
It is detected every time the excitation of is switched. When it is detected that the carriage 6 has reached the home position in this way, the process proceeds to step S404, and the CPU 21 reads the initial excitation data stored in the program memory 24 in advance and sends it to the output port 26 to execute the actual sheet feeding. Sheet feed motor 4 for N steps at a cycle longer than the excitation cycle
Drive forward. This is for aligning the phase of the sheet feeding motor 4 because the current sheet feeding position cannot be trusted.

Next, the process proceeds to step S405, and FIGS.
Position counter 1 that indicates the position of carriage 6 as shown in
The position address and the address information indicating the excitation state of each motor are indicated by 13 to indicate the carriage address (CR Adr) in the carriage memory 111 or the sheet feed memory 112.
And the sheet feed address (LF Adr). Also, since these various information became effective,
“AAH” is written to a predetermined address in the check area 114 of the nonvolatile memory 100. Then, in step S412
Proceed to the normal processing of.

On the other hand, when it is determined in step S401 that the data at the predetermined address in the check area 114 of the non-volatile memory 100 is "AAH", the process proceeds to step S406 and the non-volatile data as shown in FIGS. Position detection information and carriage excitation phase data stored in advance in the carriage memory 111 and the position counter 113 of the property memory 100 are read. And position counter 1
Whether or not the value of 13 is "0" is checked, and if "0", the process proceeds to normal processing without doing anything. In step S407, the value of the position counter 113 is other than "0", for example, "0C08H".
If so, since the decimal number indicates “3080” steps, the excitation is started from the excitation data currently designated by the carriage address (CR Adr) (FIG. 6) and the carriage motor 7 is moved by “3080” steps. Reverse. The value of the position counter 113 is decremented by -1 according to the reverse rotation of the carriage motor, and it is checked in step S409 whether the value becomes "0".

When the value of the position counter 113 becomes "0", the process proceeds from step S409 to step S410, and the home position signal input from the home position sensor 30 via the input port 31 is detected. Next in step S41
In step 1, the position address indicating the position of the carriage 6 and the address information indicating the excitation state of each motor shown in FIGS. 6 to 8 are written in the pointers of the carriage address (CR Adr) and the paper feed address (LF Adr). Also, since these various types of information are valid, "AAH" also
Writing to a plurality of predetermined addresses in the check area 114 of the non-volatile memory 100.

It should be noted that the confirmation of the home position of the carriage 6 in step S410 is for further enhancing the safety and reliability of the traveling of the carriage 6, and actually, only the value of the position counter 113 is referred to. There is no problem. Further, in order to further enhance safety, the position counter 113 is set to -1 each time the carriage motor 7 is reversely driven by one step in steps S408 to S409.
However, at that time, a signal from the home position sensor 30 may be simultaneously input to determine whether or not the carriage 6 has reached the home position. Further, in reality, the value of the position counter 113 in step S407 is "0" with a probability close to 100% when the power is turned on, and no initial setting is necessary. That is, when an abnormal operation such as intentionally turning off the power of the printer during recording is performed, the value of the position counter 113 is, for example, "0C0".
An abnormal value such as "8H" is indicated.
