Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a desktop thermal printer, and more particularly to a desktop thermal printer in which a label peeling operation can be selected.

(Prior Art) In recent years, thermal printers have been used as various output means. In particular, labels with eight codes printed by thermal printers are used for various data processing and system management. However.

Depending on the location and processing system, the printed labels may be used by peeling them off one by one, or they may be used by sending out a predetermined number of sheets from the printer with the backing paper without peeling off the labels. Conventional printers are not capable of handling each of these cases, and separate printers have to be prepared for each case, which not only increases costs, but also is not favorable in terms of operating efficiency.

(Purpose of the Invention) The present invention was made in view of these problems, and it can be carried anywhere, placed anywhere, and used easily by individuals. The purpose of the present invention is to provide a desktop thermal printer capable of sending out labels.

(Summary of the Invention) That is, the present invention is a desktop thermal printer in which a label transport roller and a platen are driven by a stepping motor of a label transport means.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 4.

FIG. 1 is a perspective view of a desktop thermal printer l according to the present invention. The printer main body 2 has an upper surface portion 3. It has a bottom part 4, an inclined upper part 5, a front part 6, and left and right side parts 7. A keyboard 8 with arranged keys is provided on the top surface 3 as data input means, and a display 9 is provided from the top surface 3 to the inclined upper portion 5 as data display means. Further, a pair of start buttons 10 are provided on the left and right side portions 7, and an opening/closing knob 11 is provided above. Further, a discharge port 13 for a mount S is formed in the front part 6 together with a lid 12 of a battery 34 storage which will be described later, and a cutter 14 is provided in this part.

Next, the internal structure of the printer 1 will be explained based on FIG. A holding part 15 for the label roll R is provided below the inclined upper part 5, and the thermal label T fed out from this part passes through a guide roller 16 and is fed out into a label passage 17. Here, the thermal label T has a structure in which label pieces with adhesive are successively temporarily attached onto a mount S as shown in FIG. This thermal label T passes through a guide roller 18 and a label sensor 19, and then passes through a thermal head 20 and a platen roller 21, where desired data such as a barcode B is printed on the thermal head 20 as shown in FIG. The thermal head 20 is rotatably supported by a support shaft 22, and the pressure applied to the head can be adjusted using a spring 23 and a screw 24.

Thermal label T printed by 20 parts of thermal head
Only the backing paper S is turned by the turning pin 25, and with the assistance of the peeling auxiliary roller 26, the label piece easily peeled off from the backing paper S is discharged out of the main body so as to come into contact with the cushion 27 for the label receiver. .

The mount S passes through a guide roller 28, is engaged with a pulling roller 29, is ejected out of the main body through an ejection port 13, and is cut by a cutter 14 as necessary. When loading the label T, by operating the opening/closing knob 11, the platen roller 21 portion is opened upward about the pivot 30, and the label T can be loaded.

Further, as shown in FIG. 4, the platen 21 includes a plunger gear 60, an idle gear 61, and an idle pulley 62.
, is connected to the stepping motor 31 via a timing belt 63 and a drive pulley 64. The pulling roller 29 includes a pulling roller shaft 65, a pulling roller gear 66,
It is connected to the stepping motor 31 via the slip mechanism 67 and the timing belt 32. The platen 21 and the pulling roller 29 are rotated as shown by arrows in FIG. 2 by a stepping motor 31 that rotates in steps in response to drive pulses.

A control circuit 33 as a control means is provided inside and below the keyboard 8, and this circuit 33 controls the sensor 19, the thermal head 20, the stepping motor 31, the keyboard 8, the display 9. It is connected to the start button 10 and a battery 34 installed below (respective connection lines are not shown).

Note that a key guard 35 is formed on the top surface 5 of the printer main body 2. Further, two pairs of legs 36 are provided on the bottom surface portion 4, so that the printer l can be placed on an arbitrary platform or the like. Also, the keyboard 8 part of the side part 7 is at the constriction part 3.
7 (Fig. 1), which is convenient when the printer 1 is held in hand and operated manually. In addition, a transfer cup) C is formed on the mount S of the thermal label T (wIJ3
Figure) This allows engagement with the pulling roller 29.

The 0-printer 1, whose operation will be explained next, can be mounted on any stand for 8M, and can be easily carried by hand to any location. Therefore, the operator can issue labels at any location of his/her choice.

In operation, when the label is used in such a manner that the label pieces are peeled off one by one, only the backing paper S is turned at the turning pin 25 portion, and the label pieces are peeled off at this portion.

If the mount S is inserted between the guide roller 28 and the pull roller 29 when loading this label, the pull roller 2
The mount S is transferred rearward by the mount 9, and play of the mount S between the turning pin 25 and the pulling roller 29 can be eliminated. Since the pulling roller gear 66 of the pulling roller 29 is equipped with a slip mechanism, the pulling roller 29
9 transports the mount S backward while slip-rotating.

The operator presses keys on the keyboard 8 to input arbitrary data. This input data can be confirmed by looking at the display 9. Next, when the start button 10 is pressed, the stepping motor 31 rotates to operate the pulling roller 29 and the label T is pulled, and at the same time, a bar code B or the like is printed by the thermal head 20 according to a desired pattern. At the same time, the label L is peeled off from the mount S at the turning pin 25 portion and discharged onto the label receiver 27.

Here, the operator can pick up the peeled label piece with his fingers, take it out of the main unit, and stick it on a desired item (not shown), such as a product, a delivery parcel, or any other item, and use it for data management. .

Furthermore, by moving the article as shown by arrow A, it is also possible to suddenly attach the label piece to the article.

Next, in order to send the label piece S along with the mount S to the inclined upper part 5 without peeling it from the mount S, the label T is moved so that one mount S is ejected as it is toward the label receiver 27 without being turned by the turning pin 25. Just load it.

In this case, the platen 21 and the thermal head 20, which are rotationally driven by the stepping motor 31, sandwich the label T and send it out.

Although this printer 1 can be used by being placed on a stand, it is also possible to use it in a portable manner by holding the waist portion 37 with the left hand and operating the keyboard 8 with the fingers of the right hand. . Note that the legs 36 may be provided with suction cups or the like in order to make it easier to stably place the printer 1 on the stand.

Although the keyboard has been described as the data input device in the above embodiment, the connection section 42 (shown by the imaginary line in FIG. 2) may be provided as a terminal of a desired computer to control the data input means. It is also possible to connect to the circuit 33 to directly obtain data from a master unit or a central computer, or it is possible to connect a pen reader or the like to this connection part 42 and input data by directly reading OCR characters or bar codes with the reader. Can also be done. In addition, the ROM of the control circuit 33 is a ROM having different software and data.
Any software or data storage can be easily exchanged by exchanging with the .

Furthermore, in this embodiment, the case where the stepping motor 31 is provided separately from the pulling roller 29 has been described, but it is possible to accommodate the stepping motor 31 inside the pulling roller 29,
From here, the platen 21 is connected via the timing belt 60 etc.
It can also be concatenated with. In this case, in order to load the label, it is necessary to provide a slip mechanism on the platen 21 side, contrary to the present embodiment, or to use a device such as a change lever to switch the connection between the platen 21 and the drive source. In other words, first, the label T is sent out at the platen 21 portion, and then the platen 21
After cutting off the drive by the switching device, the mount S is transferred by the pulling roller 29 portion, and the play is eliminated, and the platen 21 is reconnected to the drive source.

(Effects) As explained above, according to the present invention, the present invention is a small desktop thermal printer that is convenient to carry, can print labels on any part of the table, and uses a stepping motor to drive and rotate the pulling roller and platen. As a result, labels can be sent out in various ways, and various uses can be found as an output device in various fields.
