[Prior Art] There has been a desire for a recording device that combines high speed and durability.

[Purpose] In view of the above points, the present invention provides a first home position for continuous recording and a second home position when continuous recording is not performed outside the recording area in the vicinity of the recording area. To provide a high-speed, highly accurate, and durable recording device capable of reliably performing high-speed recording using a home position and standby processing when continuous recording is not performed using a second home position. The purpose is to

[Embodiment] A recording apparatus according to an embodiment of the present invention will be explained with reference to FIGS. 1 and 2. FIG. 2 is a sectional view of FIG. 1. A carriage CA having a low-tone recording head, such as an inkjet nozzle NP, is driven by a linear motor.

The linear motor consists of Mizuhisa magnet PM, magnetic plate Y1,
A closed magnetic circuit is formed by the members of the magnetic sliding shaft Y2, and a current is passed through the coil C wound around the sliding shaft Y2 around the slidable coil bobbin CB, and the carriage is integrated with the coil bobbin CB according to Fleming's left hand rule. Drive CA. Carriage sliding axis Y
The reciprocating motion on the coil C is performed by changing the direction of the current flowing through the coil C. A scale plate, for example, a slit plate OS made of a non-magnetic material, has both ends fixed horizontally to the bent end Y1T of the magnetic plate Y1 together with the sliding axis Y2, and is arranged parallel to the sliding axis Y2. carriage
CA has a coil bobbin CB of coil C, an inkjet nozzle NP, and a slit scale detection means, such as a photodiode, which is fixed with adhesives EP1 and EP2.
LE, phototransistor PT, and printed board PC are fixed. The printed circuit board PC has respective terminals, namely terminals C1 and C2 of the coil C, terminals PZ1 and PZ of the piezo PZ which is the drive source of the inkjet nozzle NP.
2. Terminals LE1 and LE2 of the photodiode LE and terminals PT1 and PT2 of the phototransistor PT are electrically and mechanically connected. All these signal lines are connected to one end FL1 of the flexible cable FL at the end PC1 of the printed circuit board PC,
The connecting portion is fixed by a presser plate P1 shown in FIG. The flexible cable FL is folded back in the middle of the cable, and at the position where the ink supply tube ST, which is supplied with ink from the tank TA, is fixed by the supply tube holding plate P2, the holding plate P2 and the cable holding plate P are connected with screws S.
Tighten and secure. flexible cable
The other end of FL2 is the connector CN in Figure 2.
The inkjet nozzle NP drives the carriage CA and controls the piezo PZ of the inkjet nozzle NP via the signal line of the flexible cable FL. Slit plate OS
is located between the photodiode LE and the phototransistor PT. As the carriage CA moves, the infrared light emitted from the photodiode LE is turned on by the slit part SS and the receiving slit (not shown) attached to the light receiving part of the phototransistor PT, which has slits of the same pitch. ,
Repeats OFF to generate timing pulse TP. This timing pulse TP detects the speed and position of the carriage CA during carriage scanning.
Controls speed, inkjet nozzle, and paper feed pulse motor PM. When printing one line, the characters are composed of a dot matrix. In response to the print command signal, the carriage starts scanning, detects the position using the timing pulse TP, and applies voltage to the piezo PZ of the inkjet nozzle at a predetermined position to eject an ink droplet and print it on the recording paper (not shown). Prints dot lines. After printing one dot line, the paper feed pulse motor
At the same time as PM is rotated one dot pitch, carriage CA is returned to the initial printing position. To feed the paper, the rotation of the pulse motor PM is transmitted at a reduced speed through a motor shaft gear (not shown) through gears G1 and G2. The final stage gear G2 is fixed to the shaft of the platen PL and is capable of feeding the paper by a predetermined amount in the row direction. This operation is repeated, and when printing of a predetermined dot line (for example, a line) in the row direction is completed, the platen PL is rotated by a predetermined distance between the lines by the pulse motor PM, and printing of one line is completed. After printing is completed, move the inkjet nozzle NP to the position HO of the cap KP and stop it.
This can prevent clogging, drying, meniscus regression, etc. of the inkjet nozzle.

As described above, in this embodiment, since the carriage sliding shaft and the scale plate made of non-magnetic material are arranged side by side on the magnetic plate of the permanent magnet, the magnetic field is not disturbed and the structure can be small, thin and simple.

Furthermore, since a rotary motor is not used to drive the carriage, there is no need for gears, links, racks, etc., and since ratchets, plungers, etc. are not used for paper feeding, an extremely quiet recording apparatus can be constructed.

In addition, since the carriage slides on the scale plate, it is possible to remove piles of ink that have accidentally adhered.
It is possible to prevent the risk that the detection means consisting of a light emitting/receiving element or the like becomes unable to respond.

In addition, since the printed circuit board is mounted on the carriage and various electrical parts are connected to it, it can be easily and inexpensively manufactured.Furthermore, since a flexible wiring board is used, it can be moved freely, and the printed circuit board and the ink supply tube can be connected in one place. It can have various features such as being simple because it is locked in place.

In the apparatus of this embodiment, the slit plate OS is provided with a slit SS as shown in the third figure, and serves both for position confirmation control and speed constant control.

In other words, the slit SS is provided to the extent that it exceeds the printing paper P, and the carriage CA is at the initial position HP or
Start moving from HO and adjust the speed until counting 8 slits SS, start printing 1 digit after counting 8 slits, and print 1 digit with 5 slits from 8 to 12.
Finish printing the digits, leave 22 digits 13 and 14 blank between adjacent digits, and repeat this process. CS at the approach slit for AS to detect the print start position
is a character slit, and BS is a blank slit, and these slits and their spacing are used to keep the carriage moving speed constant.

Figure 4 shows an example of the control circuit of this device, and the lead wires FF, FB, FV, FT, FP, and FE are integrally formed as shown as FLl of the flexible wiring board FL in Figure 1, and the carriage CA make it easier to move. In Fig. 4, when the power is turned on to the device, the control unit CC keeps the signal line _l2 open for a certain period of time.
As a result, the flip-flop F1 is reset, and the counter PC for the number of printed digits, the stage number counter 7C, the TP separation circuit TB, and the back counter BC are output via the gate AR.
Clear and start Oneshot OS. Then, the signal line lR is set to 1 and input to the gate ST.

Also, move the carriage CA to the initial position HO (5th
In order to move the coil C drive signal output line to
With lF set to 0 and lB set to 1, the carriage CA is driven in the BACK direction, that is, in the initial position direction.

The drive time of the one-shot OS is set to a time that allows the carriage CA to move to the HM position, for example, even when the carriage CA is at the leftmost position as shown in FIG.

Now, if the carriage position is HE as shown in Figure 5, and the coil drive is set as described above, the light transmitting part SS
More light enters, and a timing TP signal is output to the signal line LT via the amplifier circuit AP shown in FIG. When the TP signal is output, it becomes a signal from inverter i1 and is input to gate ST, but gate ST is closed for the time set by one-shot OS.
Both the TP signal and the output of the oscillator CPG are not input to the counter SC during that time.

During this time, the carriage moves from the HE position to the HM position, and the output of the oscillator CPG is input to the counter SC only for the time after the one-shot OS set time.

However, when the carriage CA passes through the light-transmitting part SS of the slit plate OS, the counter SC is reset by the falling edge of the signal, so the counter SC is reset.
There is no output from SC. The counter SC is set to a value that is sufficiently larger than the number of inputs from the oscillator CPG that are input between the light transmitting parts, and the carriage is
The amount of time that remains after moving to the HO position.For example, if you set it to about 1.5 times, the carriage passes the light transmitting part and moves to the HO position, the counter SC counts the set time, and the signal line lS
Output to. The control section CC is connected to this signal line lS.
It is detected that the carriage CA has moved to the initial position, and the coil drive signal line lB is set to O to stop the carriage, and the signal line lR is set to O to close the gate ST. Also, the input to the gate BG via the inverter IR becomes 1. Furthermore, D1 in Fig. 5,
D2 is a cushioning material that dampens carriage collision and collision noise, and is, for example, a foam material. print character memory
The information to be printed on the CM is transferred from the key KB to the arithmetic device.
When the flip-flop F1 is set by the print command PO in FIG. 6A, which is stored via the ALT signal, the control section CC enters the printing operation state by the set output signal line l1, and the signal line l2 is set to O for a certain period of time to reset the flip-flop F1. , clears the print digit number counter PC, stage number counter 7C, and back counter BCTP separation circuit TB via gate AR.

At this time, the one-shot OS also starts, but since the signal line lR is set to O, the gate ST is closed and does not act on the counter SC. however,
Gate BG via inverter iR is open.
After executing the above reset and clearing, the control unit CC sets the signal line l4 to 1 and opens the gate AC.
Print digit count counter PC and print digit storage register
The output of the matching circuit CO that matches the contents of PR (hereinafter referred to as print digit register PR) is detected by the signal line 15 through the gate AC. If they do not match, the signal line LF is set to 1 and the driver MD drives the coil C to move the carriage CA in the FORWARD direction.

Now, if the contents of the print digit count counter PC are O and the contents of the print digit number storage register are n digits, then
The coincidence circuit CO outputs a mismatch signal, and the control section CC detects this and performs the above driving.

As the carriage CA moves in the FORWARD direction, the detection units LE and PT move the slit plate OS, the detection signal is amplified by the amplifier AP, and the timing pulse TP is detected. This TP is connected to the TP via the gate AT which is open from the signal line lF=1.
The separation circuit TB separates the signals into 5 pulse signals TD1 to TDn for printing each digit as shown in Figure 6B, and the signals are connected to the parallel-to-serial conversion circuit PSC and the gate by the signal line l6.
First, TD1 is input to SD.

Here, the total number of printing digits for one line is stored in advance in the printing digit register PR, and the character digits to be printed are counted by the digit counter PC, and the contents of the print character memory CM are selected by the decoder DC that receives the output. do.

The selected content is controlled by the output control of the stage number counter 7C, and the selected content is transmitted to the 5th stage from the character generator CG.
Output as a bit print signal.

This 5-bit print signal is sent to the parallel-to-serial converter circuit PSC.
and its output is applied to TD1 by signal line _l9
Through the gate SD, _which is open only when the high level of Printing is achieved by ejecting one ink droplet each time a signal is input. The TP separation circuit TB in FIG. 4 includes, for example, a delay circuit D, counters K1, K2, and a JK flip-flop as shown in FIG.
JF1, JF2 is obtained by configuring the AND gates G1 to G7, NAND gates N1, N2, and inverters I1, I2 as shown in the figure, and its operation is performed by the eighth
As shown in the timing chart in the figure, predetermined signals TD1 to TDn are generated on the output line l6.

The above case explains the printing of 5 dots in the 1st row of 7 rows of a 5x7 dot matrix for the 1st digit of the printing digits in 1 line, and the 1st digit is 1. When the printing of the 5th dot in the row is completed, the control unit CC detects this through the signal line l11 and outputs a signal to the signal line l7 to increment the digit counter PC.
Do 1. And, similar to above, print digit register
Match the contents of PR and digit counter PC with circuit CO,
Find a match and gate its output via signal line l4
AC is opened and output to the signal line l5, and if the control unit CC detects a mismatch, the digit counter PC
+1 digit output print character memory
CM characters are printed using a 5-pulse signal TD2 from the TP separation circuit TB.

The operating time from +1 of the digit counter mentioned above to reading from the memory and inputting it to the parallel-to-serial converter circuit can be fully executed before 5 pulses because the operating clock of the circuit is sufficiently early with respect to TP. In this way, selective printing of 5 dots each in the 1st row and 1st column is performed using the signals TD3, TD4, and TDn.
When printing one line, the contents of the print digits register PR are matched with the contents of the print digits register PR by the matching circuit CO, and the control unit CC is connected to the signal line l4.
is set to 1 to open the gate AC, and when a match is detected by the signal line l5, the signal line l8 is set to 1 for a certain period of time.
The driver PFD is driven as shown in FIG. At this time, the control unit CC determines that the output signal line l12 of the gate AL, which is the logical product of the outputs of the stage number counter 7C, is 1.
When this does not occur, it is detected that the number of printing stages is below the seventh stage.

Then, the carriage is driven in the BACK direction by setting the signal line lF to O and lB to 1, but the gate BG is open because the signal line lR=O and the signal line lB=1, and the TP signal is sent to the back counter by the signal line lC. It is now ready to be input into BC. Back counter BC counts the number of TP signals on the slit when the carriage returns. When the back counter BC finishes counting all the TP signals, the control unit CC detects this via the signal line lBC, and the carriage is placed at a position other than the slit (the right end HP of the slit plate OS in Figure 5).
It detects that the position has been reached, and sets the signal line lB to O to stop driving the carriage in the BACK direction. Also,
When the carriage is driven in the BACK direction, the gate AT is closed because the signal line LF is O, and the TP separation circuit TB is connected.
No TP signal is input and no printing is performed when returning.

As mentioned above, the control CC is the signal line l1
2, it is detected that the printing of the seventh row of the 5×7 dot matrix has not been completed, so the printing of the next row indicated by the row number counter 7C is executed.

Now, the stage number counter 7C is incremented by 1, and the content changes from 0 to 1, indicating the second stage in the character generator CG.Similarly to the printing of the first stage above, the control unit CC sets the signal line LF to 1, and the signal line lB
Operate the driver MD with
Open AT and close gate BG. of the carriage
By driving in the FORWARD direction, the optical detection parts LE and PT shown in Fig. 2 move through the slit SS and perform optical detection to detect the timing pulse TP, and the TP separation circuit
Depending on TR, TP separation signal TD1 ~ every 5 pulses
Separate into TDn. Then, in the same way as above, the first digit character outputted from the print character register CM selected via the decoder DC by the output of the digit counter PC is outputted from the character generator CG according to the instruction from the stage number counter 7C. ,
This time, the content of stage number counter 7C is 1, so 5
The second row data of the ×7 dot matrix is output. Then, the 5-pulse signal from the TP separation circuit is outputted one bit at a time via the parallel-to-serial conversion circuit PSC, inputted to the pulse width setting circuit DS, and driven by the driver PD for a fixed time width. 2 corresponding to the second row of the ×7 dot matrix
The second stage printing of the first digit is achieved by outputting the stage signal.

Thereafter, in the same manner as the first row printing, printing is performed for the second row of the 5×7 dot matrix for all the digits.

Then, in the same way as above, when the control unit CC detects the completion of the second stage printing by the coincidence circuit CO, it executes paper feed through the signal line l8, and the counter PC for the number of printed digits and the TP separation circuit
TB, clear the back counter BC and increment the stage number counter by 1. At this time, the control section CC is
As described above, since the output signal line l12 of the gate AL is not set to 1, it is detected that printing of the seventh row of the 5×7 dot matrix has not been completed. Then, by setting the signal line lF to 0 and lB to 1, the carriage is reversed and the back counter is passed through the gate BG.
The end of counting of all TP signals is detected by the output from BC, the drive of coil C is stopped, and the carriage is returned to the position HP other than the printing slit position.

Then, printing of the next stage indicated by the stage number counter 7C, which is incremented by 1, is executed.

In the same way, the third and fourth rows of printing are executed, and after the seventh row of printing is completed, the control unit CC is set to 1.
Performs paper feed for each stage, counter PC for printing digits, TP separation circuit TB, back counter
Clear BC and increment stage counter 7C by 1.

At this time, the control unit CC detects that the output signal line l12 from the gate AL is set to 1, and detects that printing of the seventh row of the 5×7 dot matrix has been completed.

Here, the control unit CC checks the output signal line l1 of the flip-flop F1 and determines whether the signal is 1 or 0.
It is determined whether the next print command has been received. If the output signal line l1 is 1, it is detected that continuous printing is being performed because the print command for the next line has been received, and as above, the signal line lF is set to 0, lB is set to 1, the carriage is reversed, and the coil C is stopped, and the carriage in the return direction is returned to a position HP other than the print slit position in the same way as when returning each stage of the 5×7 dot matrix by the output from the back counter BC via the gate BG. Then, the driver PFD is further driven by the signal line l8.
Run paper feed times.

Then, the control unit CC stores the next print line in the print character memory, enters the print operation state for the next line, sets the signal line l2 to 0 for a certain period of time, resets the flip-flop F1, and resets the gate AR. Print digits counter via PC
and stage counter 7C, counter BC, TP separation circuit
Clear TB. At this time, the one-shot OS also starts, but since the signal line lR = 0, the gate ST
is closed and counter SC does not operate. Gate BG is also open.

Then, as in the previous line, set the signal line l4 to 1, open the gate AC, match the contents of the print digit number counter PC and the print digit number storage register PR with the matching circuit CO, and send the output through the gate AC to the signal line l5
If the detection does not match, printing is executed in the same manner as above, and the stage number counter 7C
The end of the number of printing stages is detected by the output signal line l12 via the output gate AL, and the end of the printing line is detected.

Thereafter, continuous printing is performed in the same manner.

Furthermore, if the control section CC checks the output signal line l1 of the flip-flop F1 and the signal is 0, the control section CC detects that there is no next printing command and turns the cartridge CA on to a position other than the printing slit position. Stop position same as when ON
Return to HO position.

The reason for the difference in the stop position when the carriage returns when printing is continuous and when it is not is that the shorter the time it takes for the carriage to move other than the slit to be printed, the shorter the printing time. Because of this, in the case of continuous printing, rather than returning to the stop position HO after each line of printing, the machine immediately starts traveling in the FORWARD direction for the next print when it returns to the previous stop position HP. be.

It is also possible to always return to the stop position HP without setting the stop position HO, but at the stop position HP, mechanically, the head is fixed at that position, capped, and the head is cleaned using a cleaner to remove dirt and other dirt. The stop position HO is useful because a protection means KP and a place for recovery when ink is not ejected are required. To return the carriage CA to the stop position HO, just like when the power is turned on, the signal line l2 is set to 0 for a certain period of time and the flip-flop F is
1, and then the counter PC for the number of printed digits, the counter 7C for the number of printed digits, and the TP separation circuit through the gate AR.
TB, clear counter BC, one shot OS
The signal line lR is set to 1 and is input to the gate ST, so that the output of the oscillator CPG is input to the counter only when the signal is 1. At this time, gate BG is closed via inverter iR, and back counter BC does not operate.

Then, with the signal line lF as 0 and lB as 1, coil C
to move the carriage in the return direction, and
The 1 and 0 signals of the oscillator at the counter SC
After repeating the counting and resetting of the CPG output pulses and moving to the HO position in Fig. 5, the control unit CC controls the carriage CA until it reaches the stop position HO by the output signal line lS at the end of counting for the set time of the counter SC. It detects that the carriage has moved, sets the signal line lB to 0, stops driving the coil C, and
Stop CA at position HO. And signal line lR
is set to 0, gate ST is opened, and gate BG via inverter iR is left open. Then, the driver PFD is further driven by the signal line l8.
Execute the paper feed twice and finish printing.

The stop position HP is the position where the control unit CC counts the total TP from the slit with the back counter BC, stops the coil drive, and then the carriage CA moves and stops due to inertia.

SC in FIG. 4 is a circuit for controlling the speed of the carriage CA, its details are shown in FIG. 9, and its operation timing chart is shown in FIG. 10. In the figure, the carriage CA moves through the slit plate OS by being driven by the coil, and the signals optically detected by the transmitter/receiver LE and PT are sent to the timing pulse TP via the amplifier AP.
is output to the signal line LT as described above.

4Bit shift register by output TP signal
The outputs Q0, Q1, Q2, and Q3 of SR are sequentially set every clock CP of the clock pulse generator CPG. Then, the output TP is the AND of the output obtained by inverting the signal of Q1 with the inverter iO and the signal of QO.
1 is output from AND gate AO to signal line lT1,
In addition, the output TP2 obtained by inverting the signal of Q2 by inverter i1 and the signal of Q1 is ANDed.
The signal is outputted from the gate A1 to the signal line LT2, and an output TP3 obtained by ANDing the signal of Q3 and the signal of Q2, which is similarly inverted by the inverter i2, is outputted to the signal line LT3. Signals TP1 to TP3 are shown in FIG. The TP1 signal output to the signal line lT1 is an OR gate
The flip-flop SRF is reset via RF, and the TP2 signal output to the signal line lT2 is ANDed.
The signal is input to gate A4, and gate A4 is opened for the time TP2.

In addition, TP3 output to signal line LT3 sets flip-flop FCP and outputs AND gate A3.
Release the reset by setting the output of
The next clock CP is input to the counter CCH.

Here, the counter CCH is set at the gate A3 by the signal line l2 becoming 0 for a certain period of time at the start of printing.
has been reset via the flip-flop
The FCP is reset via the gate A5, and its output sets the signal line lnR to 0 and inputs it to the gate A3 to continue resetting the counter CCH. And output Q0~Q1 of counter CCH
are all 1, that is, via the NAND gate ND, so they remain in an operating state without being reset until the end of counting. Therefore flip-flop
When FCP is set by TP3 and the counter operates and counts up to the count number n, the NAND gate
ND becomes 0, resetting the flip-flop FCP and also resetting the counter CCH.

Flip-flop SRF is also reset by signal line l2 via inverter i3 and OR gate RF. i.e. AND gates AF and AB
One input of is set to 1 and is in the operating state. This will be explained below with reference to FIG. entered
From TP(1) of TP signal, pulse signal, TP1, TP2,
TP3 is output, the flip-flop FCP is set by the signal of TP3, and the clock CP is set as a counter.
When input to CCH, counter CCH counts a predetermined number of counts, Q0, Q1
~Output to Qn. Then, until the count number n, the signal line CCO becomes 1 due to the output of the OR gate ORO, and is inputted to one side of the AND gate A4.

The other signal line lT2 of AND gate A4 has
The TP2 signal is input, and this signal is made from the TP signal. As mentioned above, the TP signal is generated by the movement of the carriage CA, and its timing and time width are related to the carriage speed. Therefore, when the carriage speed is slow, that is, TP in Figure 10.
When the TP input signal is as shown in (1), the TP2 signal due to the TP signal is not output and the gate A4 is closed until the counter CCH finishes counting, and the flip-flop SRF is lower than the TP2 signal. It remains in a reset state through OR gate RF with TP1 output at the previous timing. This does not affect the AND gates AF and AB, so they continue to drive the coil, ie, the carriage CA.

As in the case of TP(1), in the case of TP(2), (3), and (4),
The logical product of counter output CCO and TP2 signal is AND
The drive of the coil C does not change because the drive of the coil C is not controlled by the gate A4, but in order to continue the drive, the moving speed of the carriage CA gradually increases and the TP interval gradually becomes shorter. Then, at TP(5), the output signal line CCO(4) from the counter OC via the gate ORO and the TP2(5) signal are ANDed by the gate A4, and the signal line A40 is set to 1.
Then, set the flip-flop SRF.

When flip-flop SRF is set, the output changes from 1 to 0, AND gates AF and AB are closed, signal lines FM and FB are set to 0, and driver MD
is deactivated to stop driving the coil C. Even when the drive of the coil C is stopped, the carriage moves due to inertia, but the speed becomes slower. Then, the flip-flop SRF is reset via the gate RF by the next TP signal, the signal from TP1(6) caused by TP(6), and the output is set to 1 to open the gates AF and AB and drive the coil C again.

Between the TP2 (5) signal and the TP1 (6) signal, the coil drive is stopped and the speed is reduced, but as shown in Figure 9.
In the case of TP(6), since the speed has not completely decreased yet, the output signal line CC0(6) from the counter CC and the TP2(6) signal are ANDed at gate A4, as in the case of timing pulse TP(5). The flip-flop SRF is set again, gates AF and AB are closed, and the coil drive is stopped again until the TP1(7) signal from the TP(7) signal is received.

Same as above, next TP signal, TP1(7) by TP(7)
Flip-flop through gate RF with signal of
Reset SRF and open gates AF and AB to drive coil C again.

Similarly, AND of TP2 and counter output CCO
The coil C is driven by TP(7) and (8), the drive of the coil C is not stopped, and at TP(9),
As in TP(5) and (6), the drive of the coil C is stopped, and the speed control of the carriage CA is executed based on the count number n of the CP by the counter CCH.
