Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper feed mechanism of a printer used as an output device of various information devices, and more particularly to compactly store print roll paper and attach / detach replacement. The present invention relates to an easy paper feeding mechanism.

[Conventional technology]

2. Description of the Related Art Various printers have been developed and used today as output devices for information devices that process various data by computer. However, when this type of information device is used as a mobile terminal device, in order to facilitate its transportation, many related devices are required to be space-saving and combined to form a compact assembly structure.

[Problems to be solved by the invention]

Especially when an automatic paper feed mechanism is attached to the printer,
If the roll paper for printing is made to have a more compact configuration without modifying the printing mechanism, it may cause a paper jam, for example, and the work of attaching / detaching the roll paper may be impossible, resulting in damage to the device. There are difficulties.

Therefore, an object of the present invention is to provide a compact and space-saving structure, to perform proper positioning with respect to the printing mechanism portion of the printer, and also to make the roll paper attachment / detachment operation easy, downsized and manufactured at low cost. (EN) Provided is a paper feed mechanism of a printer which can be easily handled.

[Means for solving problems]

The paper feeding mechanism of the printer according to the present invention is configured such that the printing rolls are spaced apart and face each other on the side of the printing mechanism provided on one side of the printer, and are arranged on the support substrate of the printer in parallel from both sides of the printer. The angle is extended to a pair, and a pair of brackets for holding the roll paper are opposed to these angles. One of the brackets is detachably fixed to the angle by a locking claw piece, and
The other bracket is preliminarily fixed to the angle, and the positioning collars are inserted into both ends of the support shaft inserted into the roll paper, and the one bracket is attached to one end of the support shaft. Through,
After inserting the other end of the support shaft into the shaft hole of the other bracket, the one bracket is configured to be locked and fixed to a corresponding angle.

In the paper feeding mechanism, the roll paper held by the bracket arranged on the same substrate as the printer can be configured to guide the printing mechanism of the printer from the lower side to the upper side.

[Action]

According to the paper feeding mechanism of the printer of the present invention, the printer and the roll paper are arranged on the same substrate to save the space, and the roll paper has at least one of the brackets for supporting the roll paper as the fixing portion. With the detachable structure, the mechanism that supports the roll paper can be disassembled and assembled easily and quickly, and the roll paper is properly positioned using the positioning collar to prevent printing errors and paper jams. Accidents can be reliably prevented.

〔Example〕

Next, an embodiment of a paper feeding mechanism of a printer according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the paper feed mechanism of the present invention. That is, in FIG. 1, reference numeral 10 indicates a printer, and the printer 10 is provided with a required space so that a printing mechanism portion (not shown) provided on one side of the printer 10 faces the printing roll paper 12. It is fixedly arranged on the substrate 14. Angles 16 and 18 are extended in parallel from both sides of the printer 10 and fixed to the space on the side of the printing mechanism of the printer 10 on the substrate 14. Then, using the angles 16 and 18, the protective cover 20 is attached to the printer 10, while the brackets 22 and 24 having the shaft holes 21 are attached to the space side where the roll paper 12 is provided. In this case, one bracket 22 is fixed to the angle 16 to form a fixed bracket, and the other bracket 24 is detachably connected to the angle 18. Therefore, the bracket 2
The base of No. 4 is provided with a locking claw piece 26, and a notch 28 is provided in a part of the angle 18 that engages with the locking claw piece 26.

However, the support shaft 30 is inserted through the center of the roll paper 12, and the positioning collars 3 are provided at both ends of the support shaft 30, respectively.
After mounting 2, 34, one end of the fixing bracket 1
6, the bracket 24 is locked to the angle 18 with the other end of the support shaft 30 previously inserted into the shaft hole 21 of the bracket 24.

In this way, the paper feed mechanism of the printer in this embodiment can be assembled as shown in FIG. In this way, the rotatably held roll paper 12 can be set so as to be wound around the platen disposed inside the printing mechanism unit of the printer 10, for example, from below to above. In this embodiment, since the detachable bracket 24 is provided with the claw piece 26 that is elastically locked to the angle 18, the engaging / disengaging operation can be easily performed even when the bracket 24 is slightly inclined with respect to the vertical portion of the angle 18. It is possible to perform the replacement work of the roll paper 12 quickly and safely.

〔The invention's effect〕

As is apparent from the above-mentioned embodiments, according to the present invention,
The roll paper for printing is configured in such a manner that one of the brackets is detachably attached to the bracket provided on the same board in front of the printing mechanism section of the printer through an angle, with the engaging claw piece. As a result, the roll paper arranged in a space-saving manner can be attached and detached and replaced very easily and quickly. In addition, the roll paper has a positioning collar inserted on both sides of a support shaft that supports the roll paper and is supported between predetermined brackets, so that the roll paper is always positioned with respect to the printer, and the paper is always smoothly fed out. However, it is possible to reliably prevent printing errors and paper jams. Further, the bracket can be configured to be attachable / detachable by a simple process, and since the printer need not be changed in design at all, it can be manufactured at low cost and at low cost.

Therefore, the paper feeding mechanism of the printer according to the present invention has a space-saving and compact configuration, and the work of attaching and detaching the roll paper is easy. Therefore, it is effectively applied as an output device incorporated in, for example, an attache case type data processing terminal device. be able to.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and it is needless to say that various design changes can be made without departing from the spirit of the present invention.
