It is possible to load the roll paper 3 from which the paper has been removed.

FIG. 7 is a flowchart showing an example of a roll paper loading program. Referring to FIG. 7, FIG. 1, and FIG. 3, in order to load the roll paper 3, first open the cover 1 in step S1, and then insert the cover 1 of the cover detector 4 in step S2. As a result of the contact state of being released, the cover detector 4 is turned off.

Next, proceeding to step S3, the display section 5 made of light emitting diode
flashes to notify the operator that the cover 1 is open. Next, proceeding to step S4, the carriage sensor 61
is turned on and it is determined whether or not the recording head 52 is moved to the retracted position, and the carriage sensor 61 is turned on and the recording head 52 is moved to the retracted position. Then, the process proceeds to step S6, where the display section 5 is lit continuously to notify the operator that loading is possible. On the other hand, if the carriage sensor 61 is turned off in step S4, the process proceeds to step S5, where the carriage motor 58 is rotated, the recording head 52 is moved to the retracted position, and the carriage sensor 61 is turned off. Turn on.

Next, after the roll paper 3 is mounted on the roll paper holder 1a, in step S7, both ends of the roll paper 3 are pinched with fingertips and gradually inserted through the opening 7.

It becomes possible to detect whether the edge of the paper has been inserted between the drive roller 11 and the pinch roller 14.

In step S8, when the ON state of the presence/absence detector 10 is detected, the process proceeds to step S9, and as a result of rotating the paper feed motor 13 made of a pulse motor by a certain amount, the drive roller 1
1 is driven, and the roll paper 3 is conveyed to a position where the platen 15 and the first roller 16 are in contact with each other.

On the other hand, if the ON state of the presence/absence detector 10 is not detected in step S8, the process returns to step S7, and the roll paper 3
Wait until the end of the paper is inserted between the drive roller 11 and the pinch roller 14.

Next, when the rotation of the paper feed motor 13 is stopped, the process proceeds to step S]○, where the operator closes the cover 1, but
At this time, cracking occurs as the cover 1 rotates.

In step Sll, it is determined whether the cover detector 4 that detects the open state of the cover 1 has been brought into contact and turned on, and when the on state is detected, the display unit 5 is turned on. The paper guide motor 19 is rotated in the direction of arrow C in step S12, but as described above, a reduction gear mechanism (not shown) is meshed between the paper guide motor 19 and the sun gear 32. The planetary gear mechanism 27
The planetary gear 35 constituting the is about to be rotated by the sun gear 32, but the frictional force of the compression coil spring 36 acts, and the plate 33 is rotated in the C direction. At this time, the shaft 34 comes into contact with the end of the elongated hole 37, and the planetary gear 35 and the paper guide gear 28 are brought into engagement with each other.

In this way, the rotation of the paper guide motor 19 in the C direction is transmitted to the paper guide gear 28, but as described above, the paper guide gear 28 is provided with a cam 43 for controlling the rotation angle. The paper guide motor 9 continues to be driven in the direction of arrow C until the paper guide sensor 44 which contacts the peripheral surface of the paper guide motor 43 and controls the rotation angle is turned on. At this time, the bin 40, which is provided integrally with the paper guide gear 28 and is engaged with the groove 42 of the paper guide 18, moves the paper guide 18 to the guiding position on the outer circumferential surface of the platen 15. When the paper guide sensor 44 is moved to the guide position of the paper guide 18,
In step S13, it is detected whether it is in the on state. When the on state is detected in step S13,
Proceeding to step S14, the paper guide motor 19 is stopped. With the above operations, the preparation of the transport path for transporting the roll paper 3 to the end of the roll paper 3 where the second roller 20 contacts the platen 15 is completed.Therefore, the process proceeds to step S15, where the paper feed motor 13 is driven. As a result, the drive roller 11 and platen 15 are driven, and the end of the roll paper 3 is conveyed to the lower part of the paper sensor 24, and step S1
At 6, the paper sensor 24 detects the paper. Paper edge sensor 2
When the detection number 4 is performed, the process advances to step S17, and the drive of the paper feed motor 13 is stopped.

Next, the process advances to step S18, where the paper guide motor 19 is rotated in the C direction, the cam 43 turns off the paper guide sensor 44, and the paper guide 18 is rotated to the retracted position.

In step S19, it is determined whether or not the paper guide sensor 44 is in the off state. If it is determined that the paper guide sensor 44 is in the off state, the process proceeds to step S20, and the rotation of the paper guide motor 19 in the C direction is stopped. .

With the above operations, the walnuts are removed from the roll paper 3 and the second
The paper is conveyed until the end of the paper is located at the position of the paper end sensor 24 immediately after the roller 20.

(Description of the operation program of the cutter device 23) When the well-known recording operation is completed and a certain amount of the roll paper 3 is discharged from the discharge port 25, the operation program of the cutter device 23 is operated, and then the roll paper 3 is discharged from the discharge port 25. 3 is cut to a certain length, and this cutting operation is performed by the rotational movement of the paper guide motor 19 in the D direction.

FIG. 8 is a flowchart for explaining the operation program of the cutter device 23. In FIG. 8 and FIG. When 6 is pressed, the process advances to step S2 and the paper feed motor 13 is driven.
The end of the roll paper 3 is guided to the discharge port 25, and is transported from the position of the recording head 52 to the cutting position of the cutter device 23. This amount of conveyance is determined by applying the number of drive pulses corresponding to this distance to the paper feed motor 13.

Next, the process proceeds to step S3, where the paper guide motor 19 is driven in the direction of the arrow, so that the planetary gear 35 of the planetary gear mechanism 27 now meshes with the cutter gear 29.

When the paper guide motor 19 is continuously driven in the direction of the arrow in this manner, the cuff lever 4
As a result of the lever 47 being rotated downward via the lever 6, the cutting operation of the movable blade 49a cannot be performed. Here, as described above, the cam 50 is integrally formed on the cutter gear 29, and the rotation angle of the cutter gear 29 is controlled by the cam 50. Cutter sensor 51
is provided so as to come into contact with the outer circumferential surface of this cam 50, and is in the on state at the initial position, and when the cutter gear 29 rotates a predetermined amount, it is turned off by - degrees, and when it rotates once,
It will be turned on again. Therefore, when the cutter sensor 51 changes from the off state to the on state in step S4, the process advances to step S5, and the driving of the paper guide motor 19 is stopped. That is, the cutting operation of the cutter device 27 is performed. Next, the process advances to step S6, where the paper feed motor 13 is rotated in the reverse direction to transport the end of the roll paper 3 close to the paper end sensor 24, and the operation ends.

In the above description, for example, heat-sensitive recording paper, plain paper, or the like is used as the recording medium, but the recording medium is not particularly limited as long as it is a continuous roll-shaped recording medium such as a plastic film. Furthermore, although the recording portion has been described as a serial printing mechanism, for example, a thermal line head or the like may also be used.

[Effects of the Invention] As described above, in the recording apparatus of the present invention, it is easy to insert the end of the roll-shaped recording medium through the opening of the first guide member, and the end is connected to the platen. In addition, it is not necessary to insert the roll-shaped recording medium into the cover that is in the open state, and then close the cover and supply the recording medium. It is possible to provide a recording device that can prevent the occurrence of walnuts accompanying the rotation operation from the open state to the closed state, and can prevent deterioration of print recording quality caused by the walnuts.
