Abstract

The utility model relates to a printer which comprises a body support frame and an upper support frame, wherein the upper support frame can be hinged on the body support frame in a rotatable way; the abutting position of the upper support frame and the body support frame is provided with a paper cutting device and a printing assembly from top to bottom. A paper feeder is arranged under the printing assembly. A paper feeding channel, a printing channel and a paper cutting which are formed by the structure are mutually communicated. In addition, a cutter arranged on the body support frame is hinged with the body support frame through a cutter support frame and the hinging point is positioned at the other side of the body support frame. Thus, after a casing is opened, a printing head and a printing pad can be completely exposed, which is very convenient for maintenance and operation of paper feeding. The structure is simpler and more reasonable, effectively ensuring the availability and the maintainability of a printer.

Description

Printer

Technical field

The utility model relates to the printer of a kind of printed tickets etc., especially relates to a kind of impact printer.

Background technology

Development along with the stylus printing machine technology, present printer majority has all adopted a kind of being called the technology of " the simple and easy paper of going up ", the printer of this structure, it comprises main body rack and upper bracket, the rotatable hinge joint of upper bracket is on main body rack, upper bracket and main body rack joint are the paper feeder that the rubber roll of corresponding two cutting knifes that are provided with, corresponding setting and help roll constitute, corresponding printhead that is provided with and printing liner from top to bottom successively.The such upper bracket and the hinged relationship of main body rack, the passage of printing paper can be opened easily, after printing paper is installed, again can be with this pathway closure, thus realize the simple and easy paper of going up.In this printer, by the passage of printing paper is opened, avoided the work of wearing paper on the paper complicated in the traditional printer, made things convenient for user's operation.

In impact printer, operated by rotary motion has printhead and prints liner near the print position, and between also is provided with colour band, when printing paper passes through print position, print needle in the printhead impacts colour band, with the ink transfer on the colour band to printing paper, thereby realize to print.

In the printer of this kind structure, when using the reel record-paper, need to be equipped with the automatic disconnecting device that can cut off printed record-paper.Generally speaking, the automatic disconnecting device of this kind record-paper is arranged on the exit of record-paper in the printer, and this outlet is formed at the upper surface of printer.

Have in the impact printer of paper cutter at this kind, above print position, generally formed the passage of " Y " type, as shown in Figure 1, wherein, the below of this passage is a print position, above print position, the passage separated into two parts is respectively first passage and second channel, first passage is used to print the printing paper of finishing to be carried to the record-paper Way out of printer through the guiding of paper feeder, and second channel is used for guiding band and enters print position.On the structure between first passage and the second channel, also be provided with a blade of cutting knife.

In the printer of said structure, above print position, paper feeder is divided into first passage and second channel with passage, and between two passages, be provided with a blade of cutting knife, like this, after shell is opened, existence owing to the structure between two passages, the printhead and the printing liner of print position can not be come out fully, to printhead and print liner and other parts carry out maintenance maintenance and carry out on during the paper operation, all very inconvenience has caused the decline of the ease for use and the ease for maintenance of printer.

Simultaneously, because the partial structurtes of printer are crowded complicated, reduced the reliability of printer.

Summary of the invention

The utility model is exactly the problem that exists in the above-mentioned background technology, and provide a kind of and have the record-paper automatic disconnecting device, and the impact printer of colour band and the shared same passage of printing paper.

The utility model is achieved in that and comprises main body rack and upper bracket that upper bracket is rotatable to be hinged on the main body rack, it is characterized in that, at upper bracket and main body rack joint paper cutter and print components is set from top to bottom.Paper feeder is set below print components, paper feeder comprises that correspondence is arranged on rubber roll and the help roll on upper bracket and the main body rack, rubber roll and help roll form paper-feeding passage, print components comprises the corresponding printhead that is provided with and prints liner, printhead and printing liner form type channel, and this type channel and paper-feeding passage connect.Paper cutter comprises corresponding two cutter blade that are provided with, and two cutter blade form the cut paper passage, and this cut paper passage and type channel connect.The cutting knife that is arranged on the main body rack is hinged by cutter supporter and main body rack, and the corresponding upper bracket of pin joint of cutter supporter and main body rack and the pin joint of main body rack are positioned at the opposite side of main body rack.

The specific embodiment

Fig. 2 is the utility model printer cross-sectional schematic, and Fig. 3 is the partial enlarged drawing among Fig. 2.As shown in the figure, on printer main body 1, be hinged with upper bracket 2, upper bracket 2 tops are provided with first blade 21, the bottom is provided with rubber roll 6, the centre position of the rubber roll 6 and first blade 21 also is provided with prints liner 22, prints liner 22 also to be provided with first passage parts 23. with centre first blade 21

Opposite side with respect to upper bracket 2 on printer main body 1 also is hinged with second blade support 3, second blade support 3 is provided with second blade 31, position with respect to first passage parts 23 on second blade support 3 also is formed with second channel parts 33, and first passage parts 23 and second channel parts 33 form paper delivery passage 9.

On the printer main body 1 below second blade support 3, also be provided with printhead 5 and colour band 4, also be provided with help roll 7 in the position corresponding with rubber roll 6, help roll 7 and rubber roll 6 cooperatings can upwards transmit printing paper.

Fig. 4 is the schematic diagram after printer upper bracket 2 of the present utility model is opened; Upper bracket 2 along the jointed shaft Unscrew, can be gone up the paper operation easily.

Equally, behind the jointed shaft Unscrew, colour band 4 comes out fully with second blade support 3, can change or safeguard the work of colour band easily.

Because second blade support 3 and upper bracket 2 be Unscrew simultaneously, the internal structure of printer is come out fully, very conveniently carry out work such as every maintenance maintenance.

The course of work of printer of the present utility model is such: according to above-mentioned method printing paper and colour band are installed, under the cooperating of help roll 7 and rubber roll 6, printing paper is upwards carried, when printing paper process printhead, print needle bump colour band 4 on the printhead, thus printable character is on printing paper; After printing was finished, the afterbody of printing paper printing portion was during through the position of first blade 21 of passage 9 and second blade 31, and one of them does relative motion first blade 21 or second blade 31 with respect to another, thereby printing paper is cut off.

Specific embodiment of the utility model has been announced its preferred implementation, but is not limited to this kind embodiment.Those of ordinary skill in the art understands spirit of the present utility model very easily according to the foregoing description, and makes different amplifications and variation.But only otherwise break away from spirit of the present utility model, all in this patent protection domain.
