[0003]

[Problems to be solved by the device]

 However, the conventional printing device as described above does not include deformation-type tags, large-format tags, and tags made of thin paper. In other words, it is very difficult to continuously and automatically take out these deformed tags, large-format tags, and thin tags from the inside of the tag housing, and it is not possible to accurately set the taken-out tag to the printed part, so it is actually printed. Currently, stamps are used to print by hand, one by one, without using a device. In this case, not only the work efficiency deteriorates, but also the hands and the tag itself may be soiled.

The present invention has been made to solve the above-mentioned problems, and it is accurate even if it is a deformed tag, a large-sized tag, or a thin tag which is conventionally difficult to print using a printing device. It is possible to perform printing, thereby improving the work efficiency and providing a printing device that does not have a risk of soiling hands or tags.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the printing apparatus according to the present invention supplies a tag onto a tag mounting table of a main body casing having a printing unit composed of a thermal head and a platen roller, and the printing unit performs thermal printing. In a printing device configured to drive the head up and down to perform desired printing on the tag, a drive start switch for driving the thermal head is provided in the main body casing, and the printing unit is supplied separately. The tag detection unit is arranged on the back side in the direction, and the thermal head is configured to be driven based on the detection signal from the detection unit. The output signal from the drive start switch and the detection signal from the tag detection unit are arranged. It is characterized in that a changeover switch for selecting the drive of the thermal head based on and is provided, and that the above-mentioned tag detection section can be displaced in the tag supply direction. It is intended.

[0006]

[Action]

 According to this invention, when printing on a deformed tag or a large-sized tag, first, the tag is placed on the tag mounting table of the main body casing with the changeover switch being switched from the drive start switch side to the tag detection section side. At this time, the tag detection unit detects the tag end and drives the thermal head in the printing unit downward to print the desired characters or symbols on the tag. When printing on the other side, the tag is supplied to the tag mounting table of the main body casing with the changeover switch switched from the tag detection part side to the drive start switch side. At this time, the operator accurately sets the tag position at a predetermined position while visually checking the tag position, and presses the drive start switch. As a result, the thermal head in the printing unit is driven downward, and the desired character or symbol is printed on the tag. In the case of a modified tag, the tag edge may not be detected. In this case as well, printing may be performed using the drive start switch.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a printing apparatus according to the present invention, and FIG. 2 is a side view of a printing section cut vertically.

In the figure, a main body casing indicated by reference numeral 1 as a whole is a tag mounting table 5 on which a printing unit 4 including a thermal head 2 and a platen roller 3 and a tag A are placed and guided and supplied to the printing unit 4. And a storage unit 1a into which a print format and data created by using a computer (not shown) are input.

The main body casing 1 includes a drive start switch 6 for manually driving the thermal head 2 up and down, and a detection switch 7 for detecting the supply front end of the tag A and driving the thermal head 2 up and down. The drive start switch 6 is installed on the front wall of the main casing 1, the detection switch 7 is installed on the fixed table 8 provided on the back side of the printing unit 4 in the supply direction, and the tag A It is configured so that it can be displaced in the supply direction. In order to displace the detection switch 7, a long hole 9 extending in the feeding direction of the tag A is formed in the fixed table 8 as shown in the figure, and the long hole 9 can be moved along the long hole 9 and the bolt 10. It is configured by attaching the detection switch 7 to the support plate 12 which is configured to be fixed at an arbitrary position by using the wing nut 11, and a knob attached to the side wall portion of the main body casing 1, which is not shown, is rotated. The detection switch 7 may be displaced by being operated dynamically.

Each of the switches 6 and 7 is configured to selectively operate by switching a changeover switch 13 provided on the side wall of the main body casing 1.

The elevation drive unit of the thermal head 2 in the printing unit 4 is configured as follows, for example. That is, the thermal head 2 is attached to the tip of the arm rod 14 pivotally attached to an appropriate position of the main body casing 1, and the eccentric cam driven to rotate by a motor (not shown) is attached to the other end of the arm rod 14. The spring 15 is elastically contacted with 15. At this time, an arcuate recess 17 is formed in the elastic contact portion of the eccentric cam 15 with the arm rod 14. The recess 17 may be V-shaped.

A movable table 18 is provided on at least one side wall of the main body casing 1. The movable table 18 is movably supported by a guide rod 19 extending from a side wall of the main body casing 1, and a rising portion 18a is formed at an outer end thereof to hit the tag A when the tag A is set.

In the figure, 20 is an outlet for connecting to a power source, 21 is a main switch for turning the power on and off, and 22 is an interface for connecting to a computer.

Next, the operation of the above configuration will be described. First, the main unit 21 is connected to the power source through the outlet 20, the main switch 21 is pressed, and the changeover switch 13 is switched from the drive start switch 6 side to the detection switch 7 side. And on the movable table 17. At this time, the side end of the tag A is guided to the detection switch 7 while being guided by the rising portion 18a, so that the tag A is accurately set in a predetermined position, and the detection switch 7 is also set. By pushing and driving the eccentric cam 15 by 1/2 rotation by the motor, the thermal head 2 at the upper standby position is driven downward to print on the tag A between the thermal head 2 and the platen roller 3. Further, the eccentric cam 15 is further driven by 1/2 rotation to return the thermal head 2 from the lowered position to the standby position.

Further, in the case of a deformed tag or a thin tag in which the detection switch 7 cannot be used, the tag A is set to the table 5 and the tag 5 while the changeover switch 13 is switched from the detection switch 7 side to the drive start switch 6 side. It is supplied onto the movable table 18. At this time, the operator accurately sets the tag position at a predetermined position without visually recognizing the tag position and presses the drive start switch 6. As a result, the thermal head 2 is driven up and down to print on the tag A as in the above.

On the other hand, in this machine, it is necessary to accurately stop the elevation drive of the thermal head 2 at the upper standby position. For example, when the eccentric cam 15 is displaced from the normal position, the thermal head 2 is In some cases, the supplied tags may hit the thermal head 2 due to the stop of the ascending process. However, in the present invention, since the arc-shaped concave portion 17 is formed in the contact portion of the thermal head 2 with the arm rod 14, the eccentric cam 15 is guided by the arc-shaped concave portion 17 and is corrected. The lead cam 15 is always driven and stopped at the regular position.

[0017]

[Effect of device]

 As described above, according to the present invention, the up / down drive of the thermal head is selected by the changeover switch based on the output signal from the drive start switch and the detection signal from the tag detection unit. It is possible to accurately print even deformed tags, large format tags, or thin tags that were difficult to print. Therefore, even if a deformed tag, a large-sized tag, or a thin tag can be printed efficiently, there is a practical effect that there is no fear of soiling the hands or the tag itself.
