Abstract

PURPOSE:To contrive a shorter printing time, by arranging a hammer bank for printing a journal and receipts and a hammer bank for printing slips and cut papers, one on the upper side of the other, and reciprocating the hammer banks in opposite directions through a motor and a link mechanism. CONSTITUTION:A hammer bank 23 for printing a journal and receipts comprises 16 hammer springs 18 arranged side by side, whereas a hammer bank 24 for printing slips and cut papers comprises 10 hammer springs 18 arranged side by side, and printing pins 19 are mounted on a hammer carrier 17 in the state of being directed downward. The hammer banks 23, 24 are mounted respectively on hammer carriers 25, 26, each of them is fitted to a frame 30 through a link 29, and they are reciprocated in opposite directions along shafts 27, 28 by rotating a crank connected to a shaft of a driving DC motor 31. With this construction, both the journal or receipt and the slip or cut paper can be simultaneously printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a line dot impact printer device used in ECR and ROS terminals.

[Prior Art] Conventionally, this type of printer device consists of one serial head, a journal printing section, and a receipt printing section, so it cannot print on slip paper, and even if it can, it can only print one line. Ta.

[Problems to be Solved] In the conventional line dot impact printer device described above, the journal printing section, receipt printing section, and slip printing section are printed by one serial head, so they cannot be printed at the same time, so the printing time is shortened. It has the disadvantage of being long.

In addition, slip printing can only be performed on one line, and in order to print multiple lines, a separate printer device must be prepared.

Furthermore, in the case of ticket printing, it is necessary to set the paper in the printer each time, which has the disadvantage that the processing time becomes longer.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a line dot impact printer device that can simultaneously print a journal or receipt and a slip or ticket, thereby significantly shortening the printing time.

[Means for Solving the Problems] The line dot impact printer device of the present invention which solves the above-mentioned conventional problems includes a journal and a first journal for receipt printing which are disposed above and below and reciprocate so as to move in opposite directions. a print head unit having a hammer bank and a second hammer bank for slip and cut printing; a journal unit disposed above the first hammer bank and the second hammer bank; a slip and ticket conveyance unit disposed below the first hammer bank and the second hammer bank; and a ticket feeding unit behind the receipt unit. placed,
This ticket feed unit is provided with a ticket discharge port at the bottom, and is connected to the slip and ticket conveyance unit.

[Examples] Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a line dot impact printer device according to an embodiment of the present invention.

In the figure, the line dot impact printer device 1 includes a journal unit 2, a receipt unit 3, a cut feed unit 4, a print head section 5, an ink ribbon mechanism 6, and a slip and cut feed unit 7.

The journal unit 2 includes a roll paper supply section 8 and a winding section 9.
and a print platen 10, and a print head section 5.
It is incorporated on the upper right side of the

The receipt unit 3 is composed of a roll paper supply section 11, a stamp section 12, a cutter section 13, and a print platen 10, and is installed on the upper left side of the print head section 5. The ticket feeding unit 4 is arranged behind the receipt unit 3. A cut discharge port is provided in the lower part of the cut feed unit 4, and is connected to a conveying section of the slip and cut conveyance unit 7.

FIG. 2 shows the configuration of the hammer mechanism section in the print head section 5. As shown in FIG. That is, a yoke assembly consisting of two yokes 14, a permanent magnet 15, and a coil spool 16 is mounted on a hammer carrier 17, and a hammer spring 18 fixed to one end of the hammer carrier 17 is attracted to the yoke assembly. There is. A printing bottle 19 is attached to the tip of the hammer spring 18.

In this hammer mechanism, when current flows through the coil spool 16, the magnetic flux of the magnetic circuit is canceled, the hammer spring 18 separates from the yoke 14, and the tip of the printing bottle 19 presses the ink ribbon 20 and paper 21 against the platen 22. , thereby printing is performed.

FIG. 3 is a perspective view of the entire print head section 5. As shown in FIG. Hammer bank (JR) 23 for printing journals and receipts
, the hammer spring 18 shown in FIG.
They are arranged side by side. On the other hand, in the hammer bank (S) 24 for slip and ticket printing, ten hammer springs 18 shown in FIG. It is being

FIG. 4 is a perspective view showing the structure of the print head section 5 excluding other units. The hammer banks 23, 24 are mounted on hammer carriers 25, 26, respectively. These hammer carriers 25, 26 are each attached to the frame 30 via a link 29, and are rotated in opposite directions along a shaft 27, 28 by rotating a crank connected to the shaft of a drive DC motor 31. It moves back and forth as if moving. Thereby, a journal or receipt and a slip or ticket can be printed at the same time.

Printing is performed by energizing the coil of the hammer using an electric signal from a timing disk 32 gear-coupled with the rotating shaft of a driving DC motor 31 to control the horizontal printing dot spacing, and then moving the paper to another driving motor. Intermittent feed by (to form a character.

[Effects of the Invention] As explained above, the line dot impact printer device of the present invention has a hammer bank for printing journals and receipts, and a hammer bank for printing slips and slips, which are arranged above and below, and are connected via a motor and a link mechanism. Since the journal or receipt and the slip or ticket are printed at the same time by reciprocating in opposite directions, the printing time can be significantly reduced.

Furthermore, since the ticket feed unit is connected to the slip and ticket transport section, the ticket printing operation can be automated and the processing time can be further shortened.
