Abstract

The utility model relates to a miniature printer. The paper shaft of the miniature printer is telescopic, an outer sheathing pipe is sheathed on a spring and a movable shaft, and the outer sheathing pipe is matched with the shaft movable in slide by the elasticity of the spring. Both ends of a telescopic shaft are connected with the inserting section and the working section of the paper shaft. A dovetail groove is formed at opening position of the support frame of the paper shaft of the miniature printer, and the dovetail groove is communicated with a circular hole through a segment of narrow passage. When the printing paper is replaced, only the paper shaft needs to be kneaded into the compression state, and the paper shaft is pushed into the support frame. After the paper shaft is released, the paper shaft extends automatically because of the elasticity of the spring, the paper shaft comes back to the original state, and the assembling process is completed. The time is saved, the labor is saved, and the miniature printer is convenient to install. A front panel is provided with a notch, and the front panel is cooperated with a fixed key small panel. The whole front panel of the printer is a continuous surface. When the panels is installed, the key and an indicating light do not need to be aligned to the holes in the panel of the printer and be inserted in. The operation is convenient, and the labor is saved.

Description

Miniature printer

The utility model belongs to the printer field, is specifically related to a kind of mini-printer.

At present, the panel plug-in type mini-printer of the pawl of selling on the market with lock, can lean on the lock pawl of frame both sides to be fixed on the instrument panel that has installing hole, simplified the installation of mini-printer, but, because the button and the indicator lamp of protrusion are arranged on the printer support, the Kong Caineng on button and the indicator lamp aligning printing machine side plate must be inserted when after the insertion mini-printer frame mini-printer front panel being installed, there is misalignment just front panel can't be fixed inconvenient operation slightly; Moreover, respectively there is an axially open at the two ends of existing printer reel, when printer paper is installed, need a holds frame, the another hand is firmly mediated opening and the reel two ends could be pressed in the bracket groove, during the dismounting printing paper, needs firmly bracket groove to be released at the reel two ends, bracket groove is that level enters 90 ° of turnings then and blocks reel, effort, long, operation inconvenience of time when therefore changing printing paper.

The purpose of this utility model makes things convenient for when providing a kind of installation printer front panel and changing the printer paper tape, saves time, the labour-saving mini-printer.

This mini-printer comprises main circuit board 1, printing head 2, frame 3, front panel 4, reel 11, reel support 12 etc., it is characterized in that:

A) described reel 11 is flexible reel, form by movable axis 15, oversheath pipe 18, spring 20, oversheath pipe 18 is enclosed within outside spring 20 and the movable axis 15, leans on the elastic force and the movable axis of spring to be slidingly matched, and the two ends of telescopic shaft are connected with the insertion portion and the working portion of reel;

B) described reel support 12 its openings are oat tail groove structure, communicate with circular hole 24 by one section narrow passage 23;

C) described panel 4 has a breach 10, cooperates with the fixing small panel 7 of button, and making the whole front panel of printer is a continuous face.

Oversheath pipe 18 1 ends that are somebody's turn to do flexible reel are pipe shape opening, the other end is connected with the insertion portion 14 and the working portion 21 of reel for the reel stiff end, have 1～2 slotted eye 19 on the oversheath pipe 18, one end of movable axis 15 be reel another working portion 21 ' with the insertion portion 14 of reel ' be connected, the other end of movable axis has 1～2 boss 17, it axially has a spill through hole 16, movable axis is inserted 1～2 slotted eye of oversheath pipe by 1～2 boss and oversheath pipe be slidingly matched, in the protecting pipe and between the movable axis spring 20 is housed outside.

The oversheath pipe 18 that is somebody's turn to do flexible reel is the pipe shape, have 1～2 slotted eye 19 on the oversheath pipe, two movable axis, one end be reel working portion 21,21 ' with insertion portion 14,14 ' be connected, the other end has 1～2 boss 17, it axially has a spill through hole 19, two movable axis are inserted respectively in the oversheath pipe from the two ends of oversheath pipe, and 1～2 slotted eye by 1～2 boss and oversheath pipe is slidingly matched, and spring 20 is installed between two movable axis.

The utlity model has following advantage:

1. adopt the mini-printer of the flexible reel of band, when changing printing paper, only need reel is pinched to compressive state, the insertion portion of reel pushes support circular hole place by the narrow passage of support, reel is stretched to reset condition automatically because of the elastic force of spring after loosing one's grip, the reel working portion cooperates with the support circular hole finishes assembling process, saves time, laborsaving, easy for installation.

2. when the printer forward used, printing paper was installed in the below, extracted the part printer when changing printing paper and got final product from the below installation;

3. when if printer be inverted to use, printing paper up, the dovetail groove of reel support also up, printer does not need all to extract from cabinet equally when changing printing paper; If open one change the paper hole above cabinet, printer does not need to extract from cabinet with regard to replaceable printing paper, has not only made things convenient for and has changed the paper operation but also avoided printer because of often plugging the various faults that cause;

4. faceplate part and the Support for impression mechanism with printer button and indicator lamp is connected as a single entity, and becomes a fixing button small panel, and the detachable printer front panel has a breach, cooperates with the button small panel, makes the printer front panel easy for installation.
