Description

[Detailed description of the invention] The invention relates to, but is not limited to, circuit means for providing power to a print head. A dot matrix print head supported by a movable carriage that supports The present invention relates to a printing device using a code.

Background technology Use a print head carriage mounted to move back and forth in the direction This is common. Also, flat flexible cables containing multiple leads or conductors. Using multiple solenoid-type printed wire drive elements or 7 It is also well known to provide power to a cutter. Flexible 7 pull cable has its source end fixed and the other end attached to the print head the print head. It has sufficient length to move with the head.

U.S. Pat. No. 4,518,269 discloses a core frame and print head tip. Using a print head with a flexible cable pressed between Discloses the process.

One drawback of this printer design is the considerable length of time it takes to replace the print head. Installation time? It is necessary. This is the old print head's flexible Occurs because the cable must be disconnected and reconnected to the new print head. live. Moreover, great care must be taken when disconnecting and reconnecting.

A second drawback is that the flexible cable from the print head to the power supply is quite long. This means tossing the table as many times as necessary. i.e. the cost of flexible cables In addition to the use, the flexible cable is guided into the carriage and securely secured. It is said that sufficient attention must be paid to securing the cable passage and safety. That's true.

Disclosure of invention The purpose of this invention is to eliminate the above-mentioned drawbacks and to facilitate the installation and replacement of print heads. The objective is to provide a print head design that makes it possible to

According to the invention, therefore, a prism mounted on a laterally movable carriage a print head and a first print circuit secured to and extending from the print head; a circuit member connected to the flexible cable member and connected to the flexible cable member; A printer device configured to supply power to a print head, further comprising: a second printed circuit member supported by the carriage, the second printed circuit member one end of a first printed circuit member is received and secured between the first and second printed circuit members; said flexible cable means being one of said flexible cable means. Provided is a printer device fixed to the second printed circuit member at an end thereof. do.

In the printer device of this invention, the flexible cable connects the print head A separate printed circuit component supported on a carriage rather than on a printed circuit component forming part connected directly to. This reduces the length of the flexible cable and The cost can be reduced by simplifying the bull guide means. Also, print head Because the printed circuit components are not connected directly to the cable, they are relatively thin and inexpensive. Printed circuit cards can be used.

BEST MODE FOR CARRYING OUT THE INVENTION The printer according to this embodiment can print one or more receipts, journals and slips. This is a multi-functional printer that can print forms consisting of . This printer is Null only print, receipt only glint, receipt and journal print print only a document, document, or form, or print a document, form, and journal. You can sect to one of five types of prints, including:

FIG. 1 shows a print head carriage 20 supporting a print head 221e. shows a side view. The print head 22 is shown in dotted lines and the print head Indicates that the part of the assembly can be easily removed or replaced. carriage 20 is a pair of front bearings that move supported by a guide rail or support shaft 28. 24 and 26 (FIG. 2).

The rare bearing 30 is a guide rail or support shaft 32 parallel to the axis 28. It will be received and supported. The guide rail or support shaft 28 is the support of the printer 29 (Fig. i6). It is supported by an appropriate method from the side frame. The shaft 32 is also attached to the printer's side flap. Supported by Ram.

The printer carriage 2o is molded from Lexan material. It is a component, and it is assembled in a complex form to perform many functions required for carrying and handling. The body is molded. The carriage is configured to support the tip 36 of the print head 22. It includes a plate-shaped tip 34.

The tip 34 receives and secures the print head 22 with a pair of spaced apart halves. Contains 38.40t. A protrusion 42 on the front part of the tip 34 is a print head. When installing the print head 22, guide the print head 22 and place the tip in that position on the carriage. 36.

The upright plate portion 44 of the carriage 20 supports the tip portion 34.

Connecting the front bearing 24.26 and a pair of integral bridge parts 46.48. Ru. The bridge portions 46, 48 are integrally connected to the horizontal plate portion 50, and the plate portion is connected to the pre-kuji portion. 46 and 48 have an opening 52 for receiving the lower portion of the print head 22.

The carriage 20 is a printed circuit board that supplies power to the print head 22. It includes a pair of downwardly extending arms 54, 56 (FIG. 3) supporting 58 (FIG. 5).

Carriage 20 has bearings that receive end 62 (FIG. 5) of printed circuit board 58. It has a recess 60 formed just on the back side of the plug 26. The other end 64 is A recess or notch 66 that contacts the chip portion or nunnut f70, 71 that supports it. 6] z- have.

Printed circuit? - card 58 for receiving printed circuit card 76 of print head 22; It also includes a receptacle or similar connector device 72 secured to the top of the board.

Connector 72 is permanently secured to end 62 of board 58. printed circuit card 76 is sandwiched between tip 36 and coil portion 78 of print head 22. Ru.

The carriage 20 is integrally formed with the plate portion 50 and has a flat flexible cable 82 ( 1st, 2nd, 41i1) and a plurality of lugs or guides 8o spaced apart for kf has. The cable 82 is permanently fixed to the printed circuit z-P5g (Fig. 4) and the key The printer 84 etc. and the guide 86 etc. which are integrally molded as part of the carriage 2o It is delivered through the formed passage.
