Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is designed to detachably mount a cartridge containing tape-shaped print media having different widths, which is used in a printer or the like, and to feed the print media without causing lateral displacement. Of the device.

[0002]

2. Description of the Related Art The applicant of the present invention has previously filed Japanese Utility Model Laid-Open No. 2-56666.
In the publication, a cartridge used for a tape writer for producing a label tape or the like for displaying a label is proposed. This cartridge is a cartridge that is detachably attached to a printing device, and any characters that have been input to a printing tape (printing medium) such as a synthetic resin transparent film that is being drawn out from the cartridge can be used. The symbols and the like are printed by the printing unit of the printing device.

The cartridge comprises a case body and a lid body made of synthetic resin. Inside the case body, there are a winding storage portion for a print medium, an ink ribbon winding storage portion and a winding portion, and one side. A double-sided pressure-sensitive adhesive tape winding accommodating section with a release paper attached thereto is provided. Then, in a state where the ink surface of the ink ribbon and the inner surface of the print medium are aligned with each other, the ink is pulled out from the transport outlet discharge portion of the cartridge. Between the rotating platen provided in the vicinity of the transport outlet and the fixed thermal head, the ink ribbon is sandwiched and transported together with the print medium such that the ink ribbon faces the print head, and the printer is used in the printing unit. The ink is printed as a mirror image on the inner surface of the print target medium in accordance with the pattern of the characters input to.

The printed ink ribbon is drawn into the cartridge again on the downstream side of the conveyance of the printing section and wound up by the winding section. On the other hand, at the feeding section on the downstream side in the transport direction with respect to the printing section, one exposed adhesive surface of the double-sided adhesive tape that has come out of the cartridge is attached to the print medium so as to adhere to the ink adhering surface. Therefore, the medium to be printed and the double-sided adhesive tape are sandwiched by the feeding roller and the pressing roller in the feeding device, and the tape writer that is outside is cut to a predetermined size.

[0005]

By the way, it is necessary to change the width dimension of the print medium according to the size of the portion to which the tape is attached and the size of the characters to be printed. It is necessary to store the print medium and feed it so that the print medium is not laterally displaced during printing.

However, since the conventional feeding device is provided with only the feed roller and the pressing roller having the width dimension adapted to the print medium having one width dimension,
In particular, it is impossible to mount a cartridge containing a print medium wider than a predetermined width. On the other hand, when a cartridge containing a print medium having a width narrower than the predetermined width is mounted, the print medium is likely to be laterally displaced because the feed roller does not regulate the feed medium.

In order to solve this inconvenience, if a set of a feed roller and a pressing roller having a width corresponding to the cartridge having a different width is replaced each time the set is replaced, it takes time and labor for the replacement work. There was a problem that the cost would rise because it was necessary to prepare a set for that. The present invention has been made to solve these problems, and provides a feeding device for a print medium having a simple structure, which can be applied to a plurality of types of cartridges containing print media having different width dimensions. The purpose is to do.

[0008]

In order to achieve the above-mentioned object, a printing medium feeding device of the present invention is configured such that cartridges of different widths containing a tape-shaped printing medium are detachably mounted, and the printing medium is printed. The medium is fed out of the cartridge, and the power is transmitted from the drive source to the feed roller for conveying the print medium contained in each cartridge, while the print medium is sandwiched by the feed roller. A pressing roller is provided so as to be able to come into contact with and separate from the feeding roller of each cartridge, and a guide portion for restricting the movement of the printing medium in the width direction is provided. The pressing roller has a width corresponding to the minimum width dimension of the printing medium. It is formed to dimensions.

Upon rotation, the platen roller 105 presses the thermal head 104 via the link mechanism 110, and the pressing roller 103 rotates so as to press the feed roller 11. As shown in FIGS. 5 and 6, the support shaft 115 of the pressing roller 103 and the platen roller 105 are supported so as to be movable up and down with respect to the swing arm 106, and the tip of the wire spring 114 (not described in detail) is the pressing roller. The support shaft 115 of 103 is engaged with the feed roller 11 so that the pressing force on the feed roller 11 can be adjusted. Similarly, the platen roller 105 is pressed against the thermal head 104 by the urging force of a wire spring (not shown). At this time, the gear portion 112 and the pressing roller 103 of the delivery drive shaft 102
A rotational force is applied to the pressing roller 103 by the meshing of the driven gear 116 attached to the support shaft 115, and the feed roller 11 and the pressing roller 103 rotate at substantially the same peripheral speed.

In the present invention, the feed roller 11 in each of the cartridges is provided with a guide portion for restricting the movement of the printing tape 3 in the width direction, while the pressing roller 103 is provided in a plurality when the cartridge is replaced. The width dimension corresponding to the minimum width dimension of the printing tape 3 is formed. For example, a cartridge C2 provided with a printing tape 3 having a narrow width dimension H2 as shown in FIG.
And a printing tape 3 having a wide width H1 as shown in FIG.
Explaining the case of replacing the cartridge C1 with the cartridge C1 having the above, the width dimension H3 of the pressing roller 103 is formed to be substantially the same as the dimension H2 of the printing tape 3 having the narrow width.
Then, the dimension between the left and right flange portions 11b, 11b of the feed roller 11 mounted on the cartridge C2 is formed to be H2. Further, the dimension between the left and right flange portions 11b, 11b of the feed roller 11 mounted on the cartridge C1 is formed to be H1.

When it is desired to mount a cartridge containing a printing tape having a width narrower than that of the printing tape 3 having the narrow width H2, the width of the pressing roller 103 corresponds to the minimum width thereof. It suffices if it is formed to have the specified width dimension. Further, the width dimensions of the ink ribbon 4 and the double-sided adhesive tape 5 housed in each cartridge may be set to match the width dimension of the printing tape 3 to be used.

When the cartridge C1 accommodating the wide-width ink ribbon 4 and the printing tape 3 is attached to the printing apparatus 100 to execute the printing operation, the drive motor 111 operates to feed the drive shaft 102 and The drive gear 53 rotates in a predetermined direction, the printing tape 3 and the ink ribbon 4 are sent in the direction of the thermal head 104, and FIG.
As shown in FIG. 5, the printing tape 3 and the double-sided adhesive tape 5 after printing are bonded and bonded together at the nipping points of the feed roller 11 and the pressing roller 103, and then discharged to the outside. on the other hand,
The portion of the printed ink ribbon 4 is the take-up spool 40.
It is wound up in.

During the printing operation and the discharging operation, the left and right flange portions 11b, 11b of the feed roller 11 restrict the movement of the printing tape 3 in the direction (width direction) orthogonal to the conveying direction. It is possible to eliminate the disorder (shift in the width direction) of the row of and the horizontal shift (shift in the width direction) at the time of sticking with the double-sided adhesive tape 5 after printing. And
Although the width dimension of the pressing roller 103 is shorter than the width dimension of the printing tape 3 used, the printing tape 3
Since the double-sided adhesive tape 5 and the double-sided adhesive tape 5 can be attached to each other over a wide range in the substantially central portion of the width method, no inconvenience occurs.

Similarly, when the cartridge C2 accommodating the narrow-width ink ribbon 4 and the printing tape 3 and the like is mounted in the printing apparatus 100 and the printing operation is executed, substantially the same operation as described above is achieved. It should be noted that an embodiment in which only one of the pressure roller and the feed roller is driven by a meshing gear that drives the pressure roller and the feed roller may be used. Further, according to the present invention, a pressure-sensitive adhesive is applied to the back side of a printing tape which is a medium to be printed, and while this surface is covered with a release paper, normal image characters are printed on the surface of the printing tape. Like this,
It goes without saying that the present invention can also be applied to a cartridge containing the printing tape and the ink ribbon.
