[0005]

When the cover is opened and the cover is closed with the leading edge of the long paper stored in the printer pulled out to a position covering the surface of the platen, the cover is closed between the platen and the print head and between the platen and the pinch roller. Long paper is set.

[0006]

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a printer main body. An opening surface 2 is formed on one surface of the printer main body 1. A cover 3 for opening and closing the opening surface 2 is rotatably held at one end of the opening surface 2 by a fulcrum shaft 4. I have. The printer body 1 is provided with a hopper 6 which is a storage section for rotatably storing the long paper 5 wound in a roll shape. As shown in FIG. 3, the long paper 5 in this embodiment is an example in which labels 5b are arranged at regular intervals on one surface of a backing paper 5a wound in a roll shape and attached.
It may be long paper such as receipt paper.

The printer main body 1 is provided with a paper guide 7 extending from the bottom of the hopper 6 toward the opening surface 2. A portion near the opening surface 2 of the paper guide 7 is rotatable. And a label peeling body 9 along the longitudinal direction of the platen 8. Further, a battery 10 is provided in the printer main body 1 in a detachable manner.

A thermal head 12 as a print head is urged in one direction by a leaf spring 13 on a head support 11 fixed to the inner surface of the
Is held so as to be rotatable around the center. Bearings 1 urged in one direction by a spring 15 to rotatably support a pinch roller 16 are provided on both sides of the free end side of the cover 3.
7 is displaceably provided. Further, the cover 3 has a label discharge port 18 disposed between the thermal head 12 and the pinch roller 16 for discharging the label 5b.
, A concave portion 19 that functions as a handle with a finger, and a paper presser 20 that presses the floating long paper 5 in the hopper 6. The length of the cover 3 is such that the printer body 1
3 is shorter than the length of the opening surface 2, and therefore, when the cover 3 is closed, as shown in FIGS.
Between the free end of the cover 3 and the end of the opening surface 2,
A mount outlet 21 for discharging a is formed. Further, the center of the label peeling member 9 substantially coincides with the center of the label discharge port 18. Then, from the center of the label peeling body 9, the fulcrum shaft 4
Is slightly longer than the distance from the end of the thermal head 12 on the label discharge port 18 side to the center of the fulcrum shaft 4, and the distance from the contact portion between the platen 8 and the pinch roller 16 to the center of the fulcrum shaft 4. The distance is set slightly shorter than the distance to. Although not shown, the cover 3 includes
A locking claw that protrudes from both sides and is locked on both sides of the opening surface 2 of the printer main body 1 and an operation knob for retracting these locking claws inward are provided.

Next, as shown in FIGS. 5 and 6, on one surface of the printer main body 1, a power switch 22, a display element 23 for displaying a power-on state, and data from a handy scanner (not shown) are provided. Is provided.

The printer in this embodiment is a portable label printer. For this purpose, as shown in FIG. 6, an arc surface 25 is formed on at least one surface of the printer main body 1 so as to be in close contact with the waist of the operator.
Are formed with a non-slip 26 for reducing slippage with respect to the clothes of the operator, and a belt hook 27 which is hooked on the belt of the operator facing the non-slip 26.

In such a configuration, when the long paper 5 is set, the locking operation of the printer main body 1 and the cover 3 is released by operating the operation knob, and a finger is hung on the concave portion 19 of the cover 3. As shown in FIG. 1, the cover 3 is opened, and the long paper 5 wound in a roll is stored in the hopper 6 of the printer main body 1. The leading end is pulled out to a position covering the platen 8 and the label peeling body 9, and the cover 3 is closed as shown in FIG. 3 through the course shown in FIG. As a result, the leading end portion of the backing sheet 5a of the long paper 5 is pressed against the platen 8 by the thermal head 12 and the pinch roller 16, and the drawing path of the backing sheet 5a is bent at an acute angle by the label releaser 9, Lifting of the long paper 5 from the bottom surface of the hopper 6 is prevented. Such an operation is performed with the printer main body 1 attached to the waist of the operator, and the long paper 5 is inserted into the narrow gap between the platen 8 and the thermal head 12 and between the platen 8 and the pinch roller 16. Since the operation is not a threading operation, the setting of the long paper 5 is extremely easy. Furthermore, the printer main body 1 held on the belt of the operator by the belt hook 27 can improve the feeling of wearing on the human body because the non-slip 26 comes into close contact with the clothes of the operator.

In printing, when the power switch 22 is turned on, printing is performed based on data transmitted from the handy scanner. That is, the thermal head 12
Prints out with the supply voltage from the battery 10. Each time one line is printed, the platen 8 is driven one pitch at a time by a motor (not shown) using the battery 10 as a drive source, and the mount 5a is transported together with the label 5b. In this case, since the mount 5a is conveyed in a state of being bent at an acute angle by the label separator 9, the strong label 5b
Goes straight, is peeled off from the mount 5a, and is discharged from the label discharge port 18. The mount 5a is discharged from the mount discharge port 21.

When the printed label 5b is to be peeled off from the backing sheet 5a by a label pasting device (not shown) and then pasted on a product or the like, as shown in FIG. The cover 3 is closed in this state by pulling it straight without being bent by the peeling body 9. Thus, as shown in FIG. 8, the printed label 5b can be discharged from the label discharge port 18 together with the backing sheet 5a.

Incidentally, the printer main body 1 is not limited to a portable body mounted on a human body, but may be a desk-mounted one.

[0015]

As described above, the present invention relates to a cover for opening and closing an opening surface of a printer main body provided with a platen.
By providing a print head facing the platen and a pinch roller pressed against the platen when the cover is closed, the front end of the long paper is pulled out to the position covering the platen in a wide space with the cover opened. The long paper can be set between the platen and the print head and between the platen and the pinch roller by a very easy operation of simply closing the cover.
