Abstract

PURPOSE:To simplify a repair from a paper jam due to a peeling and an adhesion of label paper, by providing a paper guide having a curved face or an angle, a positioning means of the paper guide, and a means by which the paper guide is made detachable from and attachable to a frame without tools. CONSTITUTION:A paper guide 9 and a U-shaped paper guide receiver 10 are at almost central part of left and right frames 5, 6. The paper guide receiver 10 is fixed to the left and right frames 5, 6 and the paper guide 9 can be slid laterally in the paper guide receiver 10. A notch hole larger than a sectional size of the paper guide 9 is opened in the left frame 5, which can be removed by sliding the paper guide 9 onto the left side. A paper guide stopper 11 capable of being rotated centering a fulcrum 17 near the notch hole of the left frame 5 is made of a plate spring. By rotating it to the paper guide 9 side, the paper guide 9 can be half fixed. Since it can be made free by releasing it from the paper guide 9 side, an adhered label can be peeled by removing the paper guide.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a desk-top label printer that prints on label paper, and is particularly designed to simplify repair of labels that are peeled off or stuck to paper guides. It is.

[Conventional technology]

Japanese Patent Application Laid-Open No. 61-2957 to miniaturize the structure of the printer.
Many printers have a structure in which paper is wound around a cylindrical platen to reduce the paper feeding space, as in the example of the printer shown in Japanese Patent No. 5.

However, with a desktop printer with a cylindrical platen,
When printing on continuous label paper with sprocket holes, label paper that has begun to peel due to careless handling or thick label paper may peel off and stick on the tightly curved paper guide, so use label paper instead. [Problem to be solved by the invention] There is no problem with printing on continuous paper such as stock form with a conventional printer, but when using continuous label paper, bending Labels may peel off and stick to the paper guide.

Since the paper guide of conventional printers is located in the center of the device and fixed to the frame, the only way to remove stuck labels is to disassemble the printer, making repair difficult.

There are some labels that have been devised to make the label more difficult to peel off, such as the adhesive or the cut edges, but if the label is not stored properly or is handled with care, it may become easier to peel off, and peeling cannot be completely prevented. .

The purpose of the present invention is to enable a paper guide to be attached and detached without tools.
To provide a label printer having a structure in which even if a label sticks to a paper guide, it can be easily removed.

[Means for solving problems]

The present invention is characterized by providing a paper guide having a curved surface or an angle, a means for positioning the paper guide, and a means for attaching and detaching the paper guide from the frame without tools.

[Effect]

The paper guide can be removed from the printer without tools using the paper attachment/detachment means. Therefore, the stuck label paper can be removed by hand without disassembling the printer.

Moreover, the removed paper guide can be set in its original position by the positioning means and the attachment/detachment means.

〔Example〕

Hereinafter, embodiments of the present invention will be explained with reference to the drawings. 1st
The figure shows a schematic cross-sectional view of the structure of a printer that is an embodiment of the present invention, and FIG. 2 shows an enlarged view of the vicinity of the paper guide. Label paper 13 is fed by a tractor 14, aligned along a platen 12 by a paper guide 9 and rollers 11, printed by a print head 16, and cut off by a cutter 15.

At this time, the label 13a on the straight route does not come off, but the label 13b on the bent part easily comes off, and if it comes off, it sticks to the paper guide 9. The paper guide 9 is installed on the paper guide receiver 10.

FIG. 3 is an open view of a label printer according to an embodiment of the present invention. In this figure, the wood paneling, print head, platen, and rollers are removed to simplify the explanation. Cover catches 2 are provided on both sides of the front inner side of the upper cover 1, and cover catch receivers 4 are provided at positions corresponding to the cover catches 2 of the lower cover 5. The upper and lower covers are closed by the spring force of the fit between the cover catch 2 and the catch receiver 4, but they can be opened by pulling the upper cover 1 strongly upward.

Inside the cover are left and right side frames 5 and 6, and front frame 7.
, a rear frame 8, and although not shown in this figure, a printing mechanism such as a platen, a print head, a shaft, etc. are arranged within the frame.

There is a paper guide 9 and a U-shaped paper guide receiver 10 that matches the shape of the paper guide approximately in the center of the left and right frames 5 and 6.The paper guide receiver 10 is fixed to the left and right frames 5 and 6, and the paper guide 9 It can slide in the left and right directions within the paper guide receiver 10.

The left frame 5 has a cutout hole that is sufficiently larger than the cross-sectional dimension of the paper guide 9, and the paper guide 9 can be removed from the paper guide receiver 10 by sliding it to the left.

Further, a paper guide stopper 11 that can rotate about a fulcrum 17 is attached near the notch hole of the tall frame 5. The paper guide stopper 11 is made of a plate spring, and by turning it toward the paper guide 9 side, the paper guide 9 can be semi-fixed, and by removing it from the paper guide 9 side, it can be made free.

FIG. 4 shows a state in which the paper guide 9 is being removed.

The stuck label can be peeled off by removing the paper guide by the action described above.

〔Effect of the invention〕

According to the present invention, since the paper guide can be removed without disassembling the printer, troubles such as paper jams caused by peeling and sticking of label paper can be easily repaired.

This is effective for stable operation of continuous label paper in a small printer.
