DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus, such as a printer, having a paper feed system for transporting cut sheets and roll paper on the same transport path, and more particularly to completion of cueing of sheets by panel feeding. Later, the present invention relates to a paper feeding method and a recording apparatus in which handling suitable for cut sheet or roll paper is made interactive according to a user's instruction.

[0002]

2. Description of the Related Art Conventionally, a paper feeding device of a printer as a recording device generally handles cut sheets, and a plurality of cut sheets are stacked on a hopper and interlocked with the printing operation of the printer. 2. Description of the Related Art There is a well-known automatic sheet feeder for a cut sheet which automatically conveys the cut sheet positioned at the top of the sheet one by one to a printing section having a print head. On the other hand, recently, continuous paper having a form in which printing paper is wound around a core, commonly called “roll paper”, has been increasingly used as paper. When roll paper is used, the structure for supporting the roll paper is fundamentally different from the structure for supporting cut-sheet paper because the support shaft is used by penetrating the through hole of the roll paper. Therefore, in the conventional printer, the cut sheet and the roll paper are mostly made separately. A common printer that can use both cut sheet and roll paper is also provided, but its basic structure is that the sheet feeder for cut sheet and that for roll paper are attached separately to the printer body .

[0003]

In a structure in which a sheet feeder for cut sheets and a roll paper holder are separately mounted on the printer body as in the prior art, for example, a roll is provided behind the sheet feeder for cut sheets. A paper holder will be attached. Therefore, in order to hold the roll paper so as to be able to feed the roll paper over the upper end of the sheet feeder located on the front side, the roll paper holder must be enlarged inevitably. As a result, the printer as a whole becomes larger.

Further, if the roll paper is advanced using the conventional panel feeding / discharging button and is discharged out of the apparatus, the printer cannot discriminate between the cut sheet and the roll paper, so that the discharge is continued forever. As a countermeasure for this, a stop process is performed when the paper fed between the paper feed roller and the transport roller is detected, and when a signal change from the presence of the paper detection to the absence of the paper detection cannot be confirmed within a predetermined time, the stop processing is performed. By then, a lot of blank paper will come out. When it is desired to discharge after the end of printing on the roll paper, the roll paper is cut using the groove of the roll paper holder. Thereafter, when the user presses the paper supply / discharge button to discharge the paper, the paper from the recording unit to the roll paper holder becomes waste paper.

Further, in the roll paper mode, a process of discharging the roll paper without waste, a process of printing a cut line for hand cutting, a cueing process for continuously printing on the roll paper, and a printing on the next roll paper The process of waiting to enable
Many processes are required, such as a process of advancing the printed roll paper to a cutting position. Improvements in software have been desired in order to make these processes accurate and easy and to improve usability.

SUMMARY OF THE INVENTION It is an object of the present invention to feed both a cut sheet and a roll sheet by using the same transport path, feed the roll sheet by panel feeding, and after the cueing is completed, the roll sheet is fed to the roll sheet. On the other hand, it is an object of the present invention to provide a paper feeding method in which various processes are executed in an interactive manner to improve usability, and a recording apparatus for feeding paper to a recording unit and performing recording by the paper feeding method.

As shown in FIG. 3, a sheet feeder 10 for cut sheets, which is one of the main components of the sheet feeding device ASF, is inclined obliquely upward on the rear upper surface of the printer main body (indicated by a two-dot chain line). Installed. The sheet feeder 10 has a known structure, and an outline of the structure will be described below.

The lower end of the sheet feeder 10 has a screw 9
Is fixed to the printer body. The sheet feeder 10 includes side walls 12, 1 located on the left and right of the frame 11.
3 and a hopper 1 provided between the side walls 12, 13. A plurality of cut sheets are stacked on the hopper 1. The hopper 1 is configured so that the lower end swings via a hopper spring and a cam mechanism (not shown), and comes into contact with and separates from the paper feed roller 2.

An edge guide 14 for regulating the position of one end of the cut sheet in the width direction is attached to the hopper 1 so as to be movable in the left-right direction in parallel with the surface of the hopper 1. One of the side walls 12, 13 (the side wall on the near side in FIG. 3) forms a pair with the edge guide 14 and functions as an edge guide for regulating the position of the other end in the width direction of the cut sheet. Has both. That is, the inner surface of the side wall 13 whose position is fixed (the surface facing the edge guide 14) and the edge guide 1
4 forms a pair and regulates the width direction of the cut sheet from both sides, so that the cut sheet is transported straight to the printing (recording) unit (the recording head 10 shown in FIGS. 3 and 4) of the printer. It has the function of assisting you.

Reference numeral 2 in the drawing denotes a paper feed roller (the paper feed roller shaft is not shown).
The cut sheets stacked on the hopper 1 by the separation pad 3 are sent to the printing unit one by one. At the upper end of the sheet feeder 10, a detachable receiving portion 15 for detachably attaching a paper support (not shown) is provided.

Next, the roll paper holder 20 that is detachable from the sheet feeder 10 will be described. As shown in FIG. 3, the roll paper holder 20 includes a holder main body 21 located at the center, and a pair of arms 22 and 23 formed on both right and left sides of the holder main body 21.
At the center, a detachable engaging portion 24 on the holder side that can be attached to the detachable receiving portion 15 of the sheet feeder 10 is formed projectingly. In this embodiment, the sheet feeder 10
The female attachment / detachment receiving portion 15 is formed on the side, and the male attachment / detachment engaging portion 24 is formed on the roll paper holder 20 side. However, these relationships may be reversed, and the two members are not moved. Any conventionally known detachable structure can be adopted as long as the structure is detachable.

A roll paper setting area 30 is formed between the two arms 22 and 23.
A receiving portion 25 is formed inside the free end of each of the members 2 and 23. Rotation shafts 27 formed at both ends of a roll support shaft 26 are accommodated in both receiving portions 25. In this way, the roll support shaft 26 is held rotatably with respect to each of the receiving portions 25 and in a state where the movement is restricted in the lateral direction.

The roll paper holder 20, cutter scan receiving groove 28 for cutting the roll paper P _R is formed. The scan receiving groove 28 serves as a guide groove when cutting the roll paper P _R in the width direction by a cutter (not shown), along the guide groove, then the operator moves the cutter (scanning) lever, which is to be cleanly cut the roll paper P _R at that position.

The operation of this embodiment will be described. When using cut paper P _S, the printer roll paper holder 20 need not be attached to the sheet feeder 10, one by one to stack the single-cut sheet P _S of a plurality on the hopper 1 of the sheet feeder 10 To the printing unit. When using the roll paper P _R is inserted a roll support shaft 26 in a non-constrained state on the roll paper P _R (freely rotatable state roll paper P _R is relative to the roll support shaft 26), the roll support shaft 26 the two rotary shafts 27 as Komu placed in receiving portion 25 of the rolled-paper holder 20, to set the roll paper P _R in the roll paper holder 20. Then, the detachable engaging portion 24 of the roll paper holder 20 is fitted into the detachable receiving portion 15 of the sheet feeder 10, and the roll paper holder 20 is set on the sheet feeder 10.

[0027] construed from the roll paper holder 20 wind the roll paper P _R, and along a hopper 1 of the sheet feeder 10 to set the end of the roll paper P _R to the sheet conveying path of the sheet feeder 10. In this case moving the edge guide 14 to the width of the roll paper P _R, the roll paper P _R is regulated so as not to shake in the horizontal direction in the hopper 1. That is, the edge guide 1
4, and it is capable of guiding the both edges of the cut sheet P _S and the roll paper P _R. Therefore, the width direction position of the fed-out roll paper P _R is regulated, during printing, paper is understood wound from the roll paper P _R will be supplied to the straight printing unit.

[0028] construed winding of paper from the roll paper P _R is carried out by the feeding force of the transfer roller 4, since the roll paper P _R is held in a non-constrained state in the roll paper holder 20, once the transport roller Roll paper P pulled by 4
_R rotates extra due to inertial force. As a result, the paper is unwound excessively to form slack. Accordingly, back tension is not Kakekara when the roll paper P _R is fed to the printing unit, it can contribute to the improvement of sheet feeding accuracy.

In this embodiment, the feed roller 2 and the transport roller 4
Are driven by independent motors, and each motor is controlled according to a selected sheet feeding sequence. FIG. 5 shows a paper feed control block. The control unit 40 receives print information sent from a print driver of a main control unit or the like (not shown) of the recording apparatus, and selects a plurality of paper feed sequences prepared in advance based on a result of the determination of the print information. Then, the sheet feeding sequence selected by the sheet feeding command is executed, and the sheet feeding roller driving unit 41 and the conveyance roller driving unit are driven based on the sheet detection (sheet leading edge detection signal, sheet trailing edge detection signal) from the sheet detector PE. The unit 42 is controlled.

Print information includes plain paper, coated paper, OH
P sheet, glossy paper, glossy film, cut sheets such as postcards, information on paper types such as envelopes (paper type information), information on resolution (resolution information), paper feed speed,
Mode selection information such as cut sheet paper, roll paper, and panel paper supply. The panel feed is a mode in which a user operates a panel feed button provided on the panel to feed a cut sheet or a roll sheet to a cueing position. In this panel feed mode, when one print job is completed, the panel feed button is operated again when performing the next print job.

The sheet feeding sequence is an operation of rotating the sheet feeding roller 2 and the conveying roller 4 at a normal sheet feeding speed, and an operation of rotating the sheet feeding roller 2 at a sheet feeding speed (high speed mode) higher than the normal sheet feeding speed. And a combination of an operation of rotating the sheet feeding roller 2 and the conveying roller 4 forward or backward at a normal sheet feeding speed.

The control unit 40 performs a first sheet removal routine for executing an operation of advancing the sheet fed from the panel and discharging the sheet to the outside of the apparatus, and a discharging operation of the sheet fed from the panel by the reverse. A second sheet removing routine to be executed is built in, and after the cueing is completed, the sheet removing routine is executed according to a user's instruction. When the user's instruction is performed by operating the button 45 provided on the panel, this is recognized by the button operation recognition unit 40A, and the paper removal routine to be executed is determined and executed. The button operation recognizing unit 40A is provided with existing buttons (panel feed button, panel feed / discharge button)
, Or the operation time of the cut sheet and roll paper combined paper removal button.

Next, a specific example of the paper feeding method according to the present invention will be described. FIG. 6 shows a paper feed control flow for judging the operation time of the panel paper feed button to determine and execute various processes, and is a process after the completion of the cueing in the panel paper feed. FIG. 7 is a flowchart following “Yes” in step 100 of FIG. First, various routines in FIGS. 6 and 7 will be described. In the step (F), the transport roller 4 is rotated forward to perform a forward discharge operation on the sheet after the panel is fed, and at that time, the trailing edge of the sheet is detected by the sheet detector, and whether the sheet is a cut sheet is determined. It is determined whether the sheet is a roll sheet, and if the sheet is a cut sheet, the conveyance roller 4 continues to rotate forward and is discharged out of the apparatus. On the other hand, if the sheet is a roll sheet, the routine exits from the routine and stops the conveyance roller 4. Regarding the cut sheet / roll paper determination, even in the normal rotation of the conveyance roller 4 at a predetermined number of steps, it is determined that the paper is a roll paper when the presence of paper is detected, and that it is a single paper when the absence of paper is detected.

In the step (A), a discharge operation is performed for the paper after the panel paper is fed in reverse. FIG. 8 is a flowchart showing a specific example of the step (A). When the step (A) is performed, the transport roller 4 is rotated in the reverse direction (step 201). In this operation, the paper can be moved backward only to the paper-existing state where the paper detector is turned off, so that a paper jam error display is performed in order to have the user remove the paper (step 2).
02). When the paper is removed, it is determined that there is no paper by the paper detection (step 203), the roll paper mode and the panel paper feed mode are released (step 204), and the error display of the paper jam is released (step 205). If it is determined in step 203 that there is paper, the panel feed button is pressed (this operation is not related to time) (step 20).
6). By this button operation, the transport roller 4 is again rotated in reverse (step 201), and the paper of a certain length is moved backward. Repeat the above operation until the paper can be removed.

This step (A) is performed for maintenance such as replenishment of roll paper, replacement of roll paper due to change of roll paper size, change from roll paper to cut sheet paper, supply of ink, and the like. In the present invention, this is called a “maintenance mode”.

In the step (B), a cut line is printed on roll paper, fed to a position where cutting is possible, and a stop operation is executed.
FIG. 9 is a flowchart showing a specific example of the step (B). When the process (B) is executed, the transport roller 4 is rotated forward (step 301). A cut line is printed by the 1 (black) nozzle (step 302). Subsequently, in order to advance the roll paper to a position where the roll paper can be cut, the number m of forward drive steps of the transport roller 4 is set, and the counter is set to Nte.
= 0, and the transport roller 4 is rotated forward (step 304). Thereafter, paper detection is determined (step 305),
When there is paper, the counter is incremented (Nte = N
te + 1) (step 308), and it is determined whether the counter value has reached the driving step number m (step 30).
9) If it has reached the cutting position, stop it. If it has reached one, normal rotation of the transport roller 4 is continued. If the roll paper is used up before the number m of steps is reached and the paper is exhausted, the absence of paper is detected (step 305),
The roll paper mode and the panel paper feed mode are released (step 306), and the transport roller 4 is rotated forward to discharge the paper out of the apparatus (step 307).

In the step (D), a cueing operation for the next printing is executed. FIG. 10 is a flowchart showing a specific example of the step (D). When the process (D) is performed, the transport roller 4 is rotated backward (step 401). In order to complete the cueing of the transport roller 4 by forward rotation, and to eliminate backlash of the gear system at the time of forward rotation of the transport roller 4 when starting a subsequent printing operation,
The predetermined number of steps is reversed (step 402), and then the rotation is forwardly completed to complete the cueing (step 403).

In the step (E), the printed roll paper is advanced to a position where it can be cut. FIG. 11 is a flowchart showing the step (E). When the step (E) is executed, the transport roller 4 is rotated forward by a predetermined number of steps and stopped (step 500).

The above steps (B), (D), (E) and (C) described below are processings necessary to make the roll paper continue to be printed. This is referred to as “print interruption mode”.

Returning to FIG. 6 and FIG. 7, the paper feed control through the dialog will be described. The operation time of the panel paper feed button is determined based on whether or not the ON operation is longer than 3 seconds. Further, when the panel paper feed mode is selected, since the interactive system is adopted, if the panel paper feed button is not operated before executing various routines, the processing by the routine enters a standby state. Therefore, it is desirable to inform the user of the relationship between the content of the routine to be executed next and the button operation time, and to issue a warning to prompt the operation of the panel paper feed button.

When the panel feed button is operated, the presence or absence of a print signal is determined based on the selected mode information (cut sheet mode, roll paper mode) (step 100).
In the case of a cut sheet having a print signal, normal printing is started with the current sheet position (starting position) as the origin (step 101). If there is no print signal because the roll paper mode / cut sheet mode is unknown, the time of the ON operation of the panel paper feed button is determined (step 102). If the time is less than 3 seconds, the process (F) is executed, and the paper other than the roll paper is discharged out of the apparatus. If the paper is the roll paper, the transport roller 4 is stopped, and the routine exits (step 103). (A) is executed, and the roll paper is moved backward and discharged (step 104). If it is longer than 3 seconds, the process (A) is executed, and the sheet is moved backward and discharged (step 104).

Next, various processes in the roll paper mode will be described. In step 100, in the case of the roll paper mode with the print signal, the transport roller 4 is rotated forward (step 105), the current paper position (starting position) is set as the origin, and printing is started (step 106). .
In the normal rotation of the paper feed roller 4 before the printing, the roll paper is usually curled. Therefore, when printing is started from the same cue position as that of the cut sheet, head rubbing occurs and the paper is stained. In order to prevent this, when it is determined in step 105 that the paper is a roll paper, the transport roller 4 is rotated forward by a predetermined number of steps, and the leading end of the roll paper is nipped by the discharge roller. This can prevent the head from touching and rubbing the paper. Printing can also be started from the start position (“Start ON”) when paper is fed in a mode other than the panel paper and in the roll paper mode. Thereafter, when it is determined that the printing is completed or the printing is stopped (Step 108), the operation of the panel paper feed button is determined (Step 109) in order to proceed to the next process.

If there is no button operation, it is determined whether there is a print signal (step 110). If there is a print signal, the process proceeds to step 107, where the transport roller 4 is rotated forward (step 1).
11), printing is continued. If there is no print signal,
Wait for the next print. The process for making the printer stand by is hereinafter referred to as “process (C)”. If the button is operated for 3 seconds or longer, the process (A) is executed, and the sheet is moved backward and discharged (step 112). If the button is operated for less than 3 seconds, the step (B) is executed to print the cut line on the roll paper and feed the roll paper to a position where it can be cut (step 11).
3).

Subsequently, the operation time of the panel paper feed button is determined in order to proceed to the next processing (step 11).
4). In the case of button operation for 3 seconds or more, that is, as a process after cutting the printed roll paper, the process (A) is executed (step 112). When the button is operated for less than 3 seconds, the cue is performed in the step (D) to make it possible to continue printing (step 115). Thereafter, the operation time of the panel paper feed button is determined in order to step to the next processing (step 116). First, the presence or absence of a print signal is determined (step 117).
07, the transport roller 4 is rotated forward (step 11).
8) Continue printing. If there is no print signal, the step (C) is executed.

After step 113, if the user inadvertently operates the button for less than 3 seconds before cutting the printed roll paper, step (D) is executed, and the process returns to the cueing position. I will. Step (E) is provided as a measure against such erroneous operation. Here, when the step (E) is executed by operating the button for less than 3 seconds, the process returns to a position where it can be cut by the cut line printed on the roll paper (step 119).
