As described above, in the printer according to the present embodiment, by rotating the front drive motor 50, a cut sheet or continuous form A can be sucked from the front of the printer and discharged onto the stacker 35 at the rear of the printer. The rotation of the motor 57 allows the continuous paper B to be sucked from the rear of the printer and discharged below the stacker 35 at the rear of the printer, and the rotation of the front drive motor 50 and the rear drive motor 57 causes the continuous paper B to be drawn from the rear of the printer. Of the paper guide 43 for changing the discharge path of the continuous form paper B, which is a main part of the present invention, and its driving. The system will be described with reference to FIGS. FIG. 5 is a perspective view showing the configuration of the paper guide 43, and FIG. 1 is a configuration diagram showing the configuration of the drive system.

As shown in FIG. 5, the paper guide 43 guides the printed paper to the upper and lower discharge outlets of the stacker 35 in a state where the paper guide 43 is fixed at the first position shown by the solid line in FIG. 1 (or FIG. 2). As described above, a guide portion 61 for guiding a printed sheet above the stacker 35 and a guide portion 62 for guiding a printed sheet below the stacker 35 by bending a single plate material are provided in series. The paper guide 4 is provided on both left and right side edges of the guide portion 62 opposite to the guide portion 61.
In order to fix the third member 3 rotatably about the square shaft 41, a pair of left and right fixing portions 64a,
64b are formed.

One of the left and right fixed portions 64a and 64b has one fixed portion 64b for rotating the paper guide 43 to a second position shown by a dotted line in FIG. 2 by rotation of the cam 70 shown in FIG. Follower roller 65 and follower roller 65
A mounting hole 66 for fixing one end of a pull spring 72 shown in FIG. Note that the end of the paper guide 43 on the guide portion 61 side is located at the retracted position of the carriage 4 so as not to hit the carriage 4 when the paper guide 43 is moved to the second position indicated by the dotted line in FIG. 1 (or FIG. 2). The side is cut off.

Next, as shown in FIG. 1, the cam 70 is formed integrally with a driving gear 74, and the driving gear 74 is a motor gear 7 provided on a rotating shaft 76a of a cam driving motor 76.
6b. The other end of a pull spring 72, one end of which is fixed to a mounting hole 66 of the paper guide 43, is fixed to a fixed shaft 78 provided in the printer. With 72, the cam 70 is always in contact with the cam surface.

Therefore, by rotating the cam drive motor 76,
When the cam 70 is rotated from the position shown by the solid line in the drawing to the position shown by the dotted line in the drawing, the paper guide 43 is displaced from the first position to the second position. In this embodiment, the cam 70 functions as a paper discharge path changing unit, and the cam drive motor 76 functions as an actuator thereof.

FIG. 6 is a block diagram showing the configuration of a control device for driving and controlling the printer of this embodiment. As shown in the figure, the control device comprises a print head 4, a front drive motor 5
0, drive circuits 81, 82, 83, and 84 for driving the rear drive motor 57 and the cam drive motor 76, respectively.
And a control panel 86 for the user to input various command signals, a command signal from the control panel 86, detection signals from the continuous report A sensor 45, continuous report B sensor 47, and the like, and input from an external device. The control circuit 90 outputs a drive signal to each of the drive circuits 81 to 84 according to the print data, and drives the print head 4 and the drive motor.

The control circuit 90 includes a CPU 90a, an RO
The input interface 90d is composed of a microcomputer mainly including an M90b and a RAM 90c.
The above various signals are input through the
A drive signal is output via 0e.

Next, as shown in FIG. 7, the control panel 86 has a paper selection switch (ie, a continuous sheet A selection switch 91, a continuous sheet B selection switch 92, and a cut sheet) for selecting the sheet to be sucked into the printer. A selection switch 93 is provided, and a paper mode selection switch (that is, a normal mode selection switch 95 and a concurrent mode selection switch) for selecting whether to discharge the continuous form paper B from above the stacker 35 or from below the stacker 35. Switch 96) is provided.

The normal mode selection switch 95 discharges all sheets including the continuous form paper B from the position above the stacker 35, and sets the sheets to be conveyed in the printer to the print sheets selected by the sheet selection switch. Switch, and the concurrent mode selection switch 9
Reference numeral 6 denotes a state in which the leading end of the continuous form paper B is discharged from a position below the stacker 35 and the continuous form paper B is mounted in the printer. This is a switch for enabling printing on paper.

The control circuit 90 includes a continuous sheet A among the paper selection switches provided on the control panel 86.
When the selection switch 91 is operated, the continuous paper A suction processing shown in FIG. 8 is executed, and when the continuous B selection switch 92 is operated, the continuous paper B suction processing shown in FIG. 9 is executed. . Hereinafter, this processing will be described.

As shown in FIG. 8, in the process of sucking the continuous form A, it is first determined at S10 whether the normal mode or the concurrent mode is selected by the paper mode selection switch. If the paper mode is the normal mode, the process proceeds to S11, and the continuous sheet A sensor 4
It is determined whether or not 5 is in the ON state.
Is ON, the continuous paper A has already been sucked into the printer, and thus this process is terminated.

On the other hand, if it is determined in S11 that the continuous report A sensor 45 is in the OFF state, the process proceeds to S12, and it is determined whether the continuous report B sensor 47 is in the ON state. And S
In step 11, if it is determined that the continuous form B sensor 47 is in the OFF state and the continuous form paper B is not sucked into the printer, the process proceeds to S13, and the front drive motor 50 is turned off. The continuous paper A is fed by being driven in the suction direction of A.

At S11, the continuous report B sensor 47 is turned on.
If it is determined that the continuous form paper B has been sucked into the printer, the rear drive motor 57 is driven in a direction opposite to the suction direction of the continuous form paper B in S14, so that the continuous form paper B Is retracted from the suction path, and the continuous paper A
Then, the process ends.

Prior to the continuous book saving process (S14),
The user needs to cut out the already printed pages of the continuous form paper B, but in this normal mode, the continuous form paper B
Is discharged from the position above the stacker, so that the user can easily perform the processing.

Next, in S10, when it is determined that the paper mode is the concurrent mode, the flow shifts to S17 to determine whether or not the continuous sheet A sensor 45 is ON. If the continuous paper A has already been sucked into the printer while the sensor 45 is in the ON state, the process is terminated.

On the other hand, in S17, the continuous form A sensor 45
If it is determined that the state is the F state, the process shifts to S18 to determine whether or not the continuous report B sensor 47 is in the ON state. As described above, the concurrent mode enables printing on the continuous form paper A in a state where the continuous form paper B is arranged on the transport path from the rear tractor 17 to the lower side of the stacker 35 via the printing unit. Mode, so the continuous
If it is determined that the continuous form paper B has already been sucked while the sensor 47 is in the ON state, the continuous form paper A is fed in S19. In this case, the position for supplying the continuous paper A is as follows.
The paper may be fed side by side with the continuous form paper B in the width direction of the platen, or may be fed over the continuous form paper B. On the other hand, when it is determined that the continuous form paper B is not sucked while the continuous form B sensor 47 is in the OFF state, the continuous form paper B is fed in S20 to S22, and then the continuous form paper B is supplied in S23. A is fed.

In S20 to S22, the print head is first moved to a position where it does not interfere with the paper guide 43, and then the cam drive motor 76 is driven to move the position of the paper guide 43 to the position shown in FIG. 1 (or FIG. 2). The position is changed to the second position indicated by the dotted line (S20), and then the rear drive motor 57 is driven in the suction direction of the continuous form paper B so that the leading end of the continuous form paper B reaches the discharge port below the stacker 35. Paper feed B (S21), and then drive the cam drive motor 76 to
The continuous paper B is fed in such a procedure that the position of the paper guide 43 is returned to a fixed position (first position) indicated by a solid line in FIG. 1 (or FIG. 2) (S22).

Next, as shown in FIG. 9, in the process of sucking the continuous form paper B, it is first determined at S30 whether the normal mode or the concurrent mode is selected by the paper mode selection switch, and If the mode is the normal mode, the flow shifts to S31 to determine whether or not the continuous B sensor 47 is in the ON state.
If it is in the N state, the continuous paper B has already been sucked into the printer, so this processing is terminated.

If it is determined in S31 that the continuous report B sensor 47 is in the OFF state, the flow shifts to S32 to determine whether the continuous report A sensor 45 is in the ON state. Then, if the continuous form A sensor 45 is in the OFF state and the continuous form paper A is not sucked into the printer, the process proceeds to S33, and the rear drive motor 57 is driven in the suction direction of the continuous form paper B to thereby obtain the continuous form paper. B, and if the continuous sheet A sensor 45 is in the ON state, the front drive motor 50 is driven in a direction opposite to the suction direction of the continuous sheet A in step S34 to thereby remove the continuous sheet A from the suction path. After having been evacuated, the process proceeds to S35 and the continuous form paper B
Feed.

Next, in S30, when it is determined that the paper mode is the concurrent mode, the flow shifts to S37, where it is determined whether or not the continuous B sensor 47 is ON. Is ON, and the continuous paper B has already been sucked into the printer, the process proceeds to S38. Then, in S38, it is determined whether or not the continuous form A sensor 45 is in an ON state. If the continuous form A sensor 45 is in an ON state, in S39, the continuous processing is completed after the continuous form paper A is retracted from the suction path,
If the continuous form A sensor 45 is in the OFF state, the process is terminated.

That is, in the concurrent mode, printing can be performed on the continuous form paper A or the cut sheet in a state where the continuous form paper B is arranged on the transport path extending below the stacker 35. If inhaled into the printer,
Since the continuous form paper A sometimes overlaps the continuous form paper B, the presence or absence of the continuous form paper A is determined here so as to prevent such a situation (that is, to ensure that the continuous form paper B can be printed). Judgment is made and if there is the continuous form paper A, it is evacuated.

On the other hand, if it is determined in S37 that the continuous report B sensor 47 is in the OFF state, the flow shifts to S40 to determine whether the continuous report A sensor 45 is in the ON state. If the continuous form A sensor 45 is in the ON state, the flow proceeds to S41 to retract the continuous form paper A, and then proceeds to S42, where the continuous form A sensor 4
If 5 is in the OFF state, the process directly proceeds to S42.
In step S42, the cam drive motor 76 is driven to change the position of the paper guide 43 to the second position. In step S43, the continuous paper B is sucked. In step S44, the position of the paper guide 43 is moved to the first position. S21 to S2 in FIG.
The same process as in No. 3 is performed, and the process ends.

The retreating process of the continuous paper (A or B) performed in S14, S34 and S41 is performed immediately after the corresponding sensor (45 or 47) detects that there is no paper, that is, for each continuous paper. The vehicle is stopped with its tip located upstream of the position of the corresponding sensor and still with its tip held by the tractor (15 or 17).

As described above, in the printer of the present embodiment, it is possible to select whether the discharge path of the continuous form paper B is above or below the stacker 35 by the paper guide 43. For this reason, the two types of continuous paper A and B can be discharged not only in the same route but also in different routes as in the related art. Therefore, in a state where the continuous paper B is mounted on the transport path extending from the rear tractor 17 to the lower part of the stacker 35 via the printing unit,
The continuous paper A can be sucked and printed on the continuous paper A.

In this embodiment, the stacker 35 is provided in the discharge path for the continuous form paper A and the cut sheet paper.
Since the continuous form paper B can be discharged below the stacker 35, the continuous form paper B can be stably discharged even if printing is performed without cutting the continuous form paper B.

Further, in this embodiment, when the concurrent mode is selected, since the continuous form paper B is discharged from the lower side of the stacker 35, it is difficult to cut the continuous form paper B. In the state where the concurrent mode is selected, it is not necessary to retract the continuous form paper B even when printing on the continuous form paper A or the cut sheet. Therefore, it can be used as a continuous paper B for printing a copy for a copy which is generally used without cutting.

When the cut sheet is fed, the tractor 1
5 instead of feed roller 12 and pinch roller 13
Feed roller 30, pinch roller 3
Except for the point sent to 1, it is the same as the case of continuous paper A, so
The description is omitted. When printing on the continuous form paper A or B while the cut sheet is loaded, the printing is performed after the cut sheet is discharged onto the stacker 35.
