Abstract

PROBLEM TO BE SOLVED: To prevent insufficiency of the winding torque of a winding motor caused by the change in the transverse width of a mound, an ink ribbon, etc., by recognizing the transverse width of a strip-like body by a transverse width recognizing means, and controlling the voltage to be supplied to the winding motor to wind the strip-like body based on the recognized transverse width by a voltage controlling means. SOLUTION: When the issue of a label 12 is started, a judgement is made whether the issue is the peeling issue type where the label 12 is peeled from a mound 11 or of the continuous issue type where the label is issued without being peeled from the mound 11. In a case of the peeling issue type, the transverse width of the presently set mound 11 is read from the prescribed memory area of a RAM. The voltage to be supplied to a mound winding motor 10 according to the transverse width of the mound 11 recognized by a transverse width recognizing means, is read from a voltage supply table, and the read voltage is supplied to the mound winding motor 10 to drive the mound motor 10, and the label 12 is issued. This method is applicable to a winding motor 19 to wind a strip-like ink ribbon.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer for performing printing while winding a belt-shaped body such as a backing paper or an ink ribbon from which a label has been peeled off by driving a winding motor.

[0002]

2. Description of the Related Art Heretofore, a band such as a backing sheet or an ink ribbon from which a label has been peeled has been wound around a winding core mounted on a winding shaft driven by a winding motor. The driving of the winding motor for winding the mount and the ink ribbon is always performed by supplying a constant voltage.

[0003]

Therefore, when the width of the mount or the ink ribbon is large, the winding motor of the winding motor for winding the mount or the ink ribbon becomes insufficient in winding torque. For this reason, the mount may become loose at the place where the label is separated from the mount, and the releasability of the label from the mount may be reduced.

On the other hand, when the width of the mount or the ink ribbon is small, the winding torque of the winding motor for winding the mount or the ink ribbon becomes excessive. For this reason, the printing position may shift due to excessive pulling of the backing paper or ink ribbon,
Printing may be faded.

In view of the above, the present invention provides a method for winding a backing sheet or an ink ribbon from which a label has been peeled, even if the width of the band such as the backing sheet or the ink ribbon is changed. It is an object of the present invention to provide a printer that can prevent the printer from becoming excessive.

[0006]

According to the first aspect of the present invention,
A plurality of strips having different widths can be selectively installed, and the width of the strip is recognized in a printer that winds the strip by driving a winding motor on the selectively installed strip. There is a width dimension recognizing means, and voltage control means for controlling a voltage supplied to the winding motor based on the width dimension recognized by the width dimension recognizing means.
Therefore, the voltage supplied to the winding motor driven for winding the band is controlled by the voltage control means based on the width of the band, so that winding is performed when the width of the band is large. When the torque is insufficient or the width of the band is small, it is possible to prevent the winding torque from becoming excessive.

One end of the mounting shaft 17 and the winding shaft 18 is rotatably held by the side plate of the lid case 3, and protrudes in the width direction of the label-backed sheet 4 held in the holding recess 5. A gear 21 is fixed to one end of the winding shaft 18, and the gear 21 is connected to a gear 22 fixed to a rotation shaft of the ink ribbon winding motor 19 via an idle gear 23.

The label-backed sheet 4 and the ink ribbon 1
6 is such that any width can be detachably attached as long as it is narrower than the thermal head 20.

FIG. 2 is a block diagram showing a hardware configuration of the label printer. The CPU 24 for performing various processing operations includes a ROM 25 in which program data of the processing performed by the CPU 24 is stored, and a RAM in which a large number of memory areas for storing various data are formed.
26, a communication interface 27 for communicating with a host computer, etc.,
0, a motor controller 29 for controlling the mount winding motor 10, a pulse motor controller 31 for controlling a pulse motor 30 for transporting the labeled mount 4 by rotating the platen 6, and The ink ribbon winding motor 19
, An I / O port unit 34 for inputting output signals from various sensors 33, and the like. The RAM 26 has a width dimension of the mount 11 and
A voltage supply table is set in which voltage values to be supplied to the mount winding motor 10 are set according to the width of the mount 11.

This label printer has a mount 1 to be used.
1 is provided with a width dimension recognizing means for recognizing the first width dimension, and a voltage control means for controlling a voltage supplied to the mount winding motor 10 based on the width dimension of the mount 11 recognized by the width dimension recognizing means. . The data of the width of the mount 11 to be used is input together with the print data from the host computer and stored in a predetermined memory area in the RAM 26. The width dimension recognition means and the voltage control means are processes performed by the CPU 24 using data stored in the RAM 26 in accordance with the program data stored in the ROM 25.

A control operation for supplying a voltage corresponding to the width of the mount 11 to the mount winding motor 10 to issue the label 12 and wind the mount 11 will be described with reference to the flowchart of FIG. First, it is determined whether or not the issuance of the label 12 has started (step S1). If it has started, it is determined whether the label 12 is to be peeled and issued from the backing paper 11 or is to be issued continuously without being peeled from the backing paper 11 (step S2).

In the case of the issuance of the peeling, the currently set width of the backing sheet 11 is read from a predetermined memory area of the RAM 26 (step S3), and the width recognition unit is executed. Then, a voltage value to be supplied to the mount winding motor 10 is read from the voltage supply table according to the width size of the mount 11 recognized by the execution of the width dimension recognition means (step S4), and read to the mount winding motor 10. The supplied voltage is supplied to drive the mount winding motor 10 (step S5) to issue the label 12 (step S5).

In such a configuration, when the label 12 is peeled off and issued, the voltage to be supplied to the mount winding motor 10 in accordance with the previously input width of the mount 11 is obtained from the voltage supply table. When the width of the mount 11 is small, the voltage supplied to the mount winding motor 10 can be increased. When the width of the mount 11 is small, the voltage supplied to the mount winding motor 10 can be reduced. .

For this reason, when the width of the mount 11 is large, it is possible to prevent the winding torque of the mount winding motor 10 from becoming insufficient, and the mount 11 is separated from the mount 11 at the place where the label 12 is separated from the mount 11. Can be maintained in a moderately stretched state, and the label 12 from the mount 11 can be maintained.
Can be smoothly separated. On the other hand, when the width of the backing sheet 11 is small, it is possible to prevent the winding torque of the backing sheet winding motor 10 from becoming excessive, and to prevent the printing position from being shifted or the printing to be blurred due to excessive pulling of the backing sheet 11. Can be prevented.

In the present embodiment, the mount 11 has been described as an example of a band, and the mount motor 10 has been described as an example of a winding motor. The present invention may be applied to the ink ribbon take-up motor 19 for winding, and the voltage supplied to the ink ribbon take-up motor 19 may be increased or decreased according to the width of the ink ribbon 16 being used. Ink ribbon 1
6 is made of an extremely thin sheet-like member, the ink ribbon 16 sags and wrinkles may be generated, and the ink ribbon 16 may be cut when the tension is strong. However, such a problem is eliminated by setting a proper voltage.

Further, in the present embodiment, an example has been described in which the data of the width of the mount 11 used is input to the printer from the host computer in advance. A sensor for detecting the lateral width may be provided, and the sensor may detect the width, or the interval between the paper guides in the width direction of the paper may be detected.

[0019]

According to the printer of the present invention, the width of the band is recognized by the width recognition means, and the voltage supplied to the winding motor for winding the band based on the recognized width. Is controlled by the voltage control means, so that the voltage supplied to the winding motor can be increased when the width of the band is large, and the winding motor is controlled when the width of the band is small. The supplied voltage can be reduced. Therefore, when the width of the band is large, it is possible to prevent poor winding due to insufficient winding torque of the winding motor, and when the width of the band is small, winding of the winding motor is prevented. It is possible to prevent winding failure due to excessive torque.
