Reference numeral 8 denotes a paper feeding unit, which is responsible for feeding the roll paper 11 and the cut sheet 12, and the paper feed roller 7a and the paper pressing roller 7b for feeding the roll paper 11 are located near the center of the width of the roll paper 11. There is. The paper pressing roller 7b is rotatably held at the tip of the platen lever 3a.

Reference numeral 14a denotes a paper guide, which forms a predetermined gap with the opposite paper guide bottom 14b to guide the roll paper 11 to the printing section. Reference numeral 10a denotes a set pressing lever which is rotatably held by a frame and rotated by a plunger (not shown) similarly to the rotation of the platen lever 3a. A set pressing roller 10b which is rotatably held at all times is rotated. Driven roll paper setting roller 10d
It waits at a position away from the roll paper 11 and presses the plunger only when electricity is applied to feed the roll paper 11 to the paper feed portion 8.

Reference numeral 15b denotes a pair of roll paper rotation rollers rotatably arranged on the frame. The roll paper rotation shaft 15d is attached to the roll paper rotation shaft 15d by a spring clutch mechanism and the roll paper rotation shaft 15d rotates in the direction of arrow E to rotate the roll paper. If the roll paper rotation roller 15b rotates in the direction of arrow E while the roll paper rotation shaft 15d rotates in unison with the shaft 15d, the spring 15e loosens from the shaft and roll paper rotation roller 15b.
It has a mechanism that rotates only.

Further, on the driving side of the roll paper rotating shaft 15d, there is a pulley gear 15c meshing with a motor gear 20 directly connected to a roll paper motor (not shown), and on the outside thereof is a pulley 15c.
a is provided, and is connected by a belt 15f to a pulley 15a arranged at the end of the other roll paper rotation roller.

The pulley gear 15c is meshed with a set roller gear 10e that rotates integrally with the roll paper setting roller 10d. Reference numeral 22 is a roll paper detector of a micro switch, in which a part of the actuator 22a is set on the paper path and is switched by the rotation of the actuator 22a. The roll paper 11 has an end portion having a diameter larger than the outer diameter of the roll paper, and an insertion guide portion 11b formed of a resin such as a polyester film is fixed by an adhesive agent 11d. Further, the roll paper 11 is peeled off so as not to be unrolled. It is temporarily fixed by the adhesive 11c having the property. Furthermore, perforations with long ends are arranged at the rear of the temporary adhesive 11e.

Next, the operation will be described. Roll paper 11
When the recording paper is set in the printer, when a recording paper exchange command is input in step S1, a roll paper motor drive signal is input in step S2 and the timer is started at the same time. The motor gear 20 rotates in the direction of the arrow H and meshes with the pulley gear 15c and the pulley 15a.
The other pulley 15a is also rotated in the direction of arrow F by 5f. Also, the set roller gear 10e is also a pulley gear 15c.
The set roller gear 10 is driven to rotate because it meshes with
The roll paper setting roller 10d fixed to e is also rotated in the arrow J direction.

When the roll paper 11 is thrown in a state where the roll paper rotation roller 15b is rotating in the direction of arrow E, a rotational force is applied to the outer periphery of the roll paper 11 by the roll paper rotation roller 15b, and the roll paper 11 is indicated by arrow G. Is rotated in the direction. The rolled roll paper 11 is inserted into the insertion guide portion 11b.
Since the diameter of is larger than the diameter of the roll paper, the insertion guide 1
Since the front end of 1b is always away from the outer periphery of the roll paper 11, the front end is guided to the opening 14c when the roll paper 11 is rotated, and the insertion guide part 11b is rotated when the roll paper 11 is further rotated. Paper guide top 14a and paper guide bottom 14b
The roll paper detector 22 is turned on by pushing the actuator 22a on the path through the gap between the roll paper setting roller 10d and the roll paper set roller 10d.

If the actuator 22a cannot be operated without guiding the tip of the insertion guide portion 11b to the paper path due to some abnormality, the detection signal of step S3 is not detected and the time measured by the timer exceeds a predetermined time. Therefore, in step S5, the roll paper motor is stopped and an error is displayed to inform the operator of the abnormality, thereby preventing a failure due to heating of the motor and preventing time loss.

Next, if it is confirmed that the detection signal is ON in step S3, the platen plunger 28 is detected in step S6.
Also, the timer is reset and the timer is restarted at the same time when the voltage is applied to the set presser plunger (not shown). When applied to the platen plunger 28, the plunger shaft moves in the direction of arrow A and the platen lever 3a rotates in the direction of arrow B, so that the gap between the platen 3 and the printing element 1a becomes large and the roll paper is easily transported. , Paper pressing roller 7b
Is separated from the paper feed roller 7a, the insertion guide portion 11b
Become easier to pass through.

When applied to the set presser plunger, the set presser lever 10a is rotated in the direction of arrow L, and the insertion guide portion 11b is nipped by the roll paper set roller 10d and the set presser roller 10b which are rotating in the direction of arrow J. It receives a strong feeding force and is conveyed to the printing unit 8. Roll paper 11
When the insertion guide portion 11b is conveyed by a strong feeding force, the roll paper 11 is peeled off from the adhesive 11c adhered so that the roll is not unrolled, and is conveyed while the roll is unrolled. After a lapse of a predetermined time in which the front end of the roll paper fixed to the insertion guide portion 11b of the roll paper 11 is sufficiently fed through the printing portion, in step S8, application to the roll paper motor, the set presser plunger and the platen plunger 28 is performed. Be stopped.

When the application to the set presser plunger is stopped, the set presser roller 10b is rotated by a spring (not shown) so that the set presser roller 10b is separated from the roll paper set roller 10d and the function of conveying the roll paper 11 is stopped. It Similarly, when the application to the platen plunger 28 is stopped, the spring 3
The platen 3 is rotated in the direction of arrow C by
a and a paper pressing roller 7b which are arranged to face a with a predetermined gap.
Presses the roll paper 11 against the paper feed roller 7a whose rotation is controlled, and the roll paper 11 is conveyed by the paper feed unit 8 and the roll paper 11 in the supply device is supplied without rotation.

When the roll paper 11 is rotated from the outer periphery of the roll paper 11 in the direction of arrow F, the diameter of the spring 15e of the roll paper rotating roller 15b increases, so that the spring 15e slides on the roll paper rotating shaft 15d and the roll paper rotating roller 15b moves. Roll and roll 11
Rotates smoothly to improve paper feeding accuracy.

Next, after the insertion guide portion 11b is sufficiently conveyed from the printing portion, if there is a cutter mechanism, it is cut by the cutter mechanism. If there is no cutter mechanism, the roll paper 11 is removed by using perforations arranged behind the leading end of the roll paper 11. Since the perforations are longer at both ends of the width of the roll paper 11, they are very easy to remove.

Next, an example of the control means of the present invention will be described with reference to the block diagram of FIG. The control unit is a timer 13 for measuring time, a RAM for temporarily storing data being processed.
4, ROM 5 for storing programs, CPU 6 for overall control of the programs, electromagnet drive circuit 17 for paper feed / printing, etc., motor drive circuit 1 for driving motors
8 and a detection circuit 9 for detecting a timing signal and the like. A portion 10 surrounded by a broken line portion on the right side shows the printer body side.

FIG. 10 shows a second embodiment of the roll paper 11, but the difference from the first embodiment is that the insertion guide portion arranged at the end is not made of resin and the roll paper is bent outward. The point is that they are formed by bonding with an adhesive 11f. By doing so, the insertion guide portion has increased rigidity and has a similar function, but if it is thin and lacks rigidity, it may be bonded twice or three times. When using, if the insertion guide part is made of paper, the curl state may change due to the environment such as the influence of moisture in the atmosphere depending on the storage method and the tip may not separate from the outer diameter of the roll paper. At that time, since the operator recovers by manually squeezing the tip, it is used as in the embodiment.

When the roll paper is folded in this way, it is cheaper because it can be easily manufactured because it is not necessary to bond other parts and the like, and the tip end portion of the side to be used is also easy to dispose.
