Abstract

PURPOSE:To enable to reduce the number of component parts and to enhance reliability, by a method wherein a type wheels on which a desired type selected by a selecting means is aligned is rotated from a journal printing position to a receipt printing position. CONSTITUTION:When a type wheel shaft 11 is rotated by a printing command and a type pawl 13 and a spline groove 12 come to positions synchronous to a desired type chip 10, the desired type chip 10 at each digit place is engaged into the spline groove 12 and is rotated, by operations of an electromagnet 17 and selecting means 12-19. Then, when the type chip 10 is inked by a journal inking roller 20 and is stopped at the journal printing position by a Geneva stop or the like, a recording paper 2 is pressed by a journal printing member 1 to print, the type wheel is rotated again, and a receipt printing paper 6 is printed in a similar manner by a receipt inking roller 21 and a receipt printing member 5. Thereafter, the desired type chip 10 selected is returned to a stand-by position by the selecting means 12-19 and is stopped. Accordingly, the number of component parts can be reduced, and reliability can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an IO for printing on receipt paper and journal paper.
Regarding printers for R.

IcOR prints on traditional receipt paper and journal paper
Even though the characters printed on receipt paper and journal paper are often the same, printers have a type wheel for journal printing of the same type as a type wheel for receipt printing, and can print the same characters on journal paper and receipt paper. was.

The present invention takes into full consideration the characteristic of the 11OR printer that the characters printed on the register F and the journal are often the same, and enables journal printing by moving the type wheel for printing receipts. The purpose of the present invention is to provide an inexpensive I@B printer by greatly reducing the number of parts by allowing the selection trigger electromagnet and type wheel to be used in common with the receipt type in a journal printing device.

The present invention will be explained below using examples.

FIG. 1 is a side cross-sectional view showing an embodiment of the present invention, in which 1 is a journal printing member (first printing means) that performs first printing, and a journal printing member 2 is printed via a journal printing paper 2. Print suppression. Reference numeral 3 denotes a journal paper feeding roller that generates a pressing force together with the journal paper pressing roller 4 and feeds the journal printing paper 2. 5 is a receipt printing member (second printing means) that performs second printing. Reference numeral 6 indicates printing paper for receipts, 7 indicates a receipt paper feeding roller, and 8 indicates a receipt paper pressing roller. Reference numeral 9 denotes a type wheel having a plurality of type chips 10 for characters, symbols, etc. arranged around its outer periphery, and is supported on a type wheel shaft 11 . Reference numerals 12 to 19 indicate selection means for aligning and stopping desired type chips 10 at the first printing position. A spline groove 12 is provided on the outer periphery of the type wheel shaft 11 and engages with a protrusion 13g of the type mold 13. The type mold 13 is supported by a portion of the type wheel 9, and is given a spring force in the rotational direction by a type mold spring 14. Further, the type mold 16 is held at the position shown in the figure by the type claw holding member 15 and the detent spring 16. 17 is an electromagnet coil, 18 is an electromagnet core, and 19 is an electromagnet suction plate, a part of which is engaged with the type claw holding member 15.

20 is a journal ink roller which is an inking device that performs the first printing, and 21 is an inking device which is a 7-domain ink roller that performs the second printing.

Next, the operation of one printing cycle will be explained using the timing chart shown in FIG. 2. First, to explain the selection process, when a print command is issued from the printer control unit (not shown), the motor (not shown)
rotates, and the type wheel shaft 11 rotates in the direction of the arrow.

When the spline groove 12 facing a part of the type mold 13 comes to a position where it is synchronized with the desired type chip 1o, the printer control section starts energizing the electromagnetic coil 17, and the selection means 12 to 19 operate to select the respective one. The desired character chip 1o of the digit engages with the stripe line groove and rotates. Next, proceed to the first inking step. The type chip 10 continues to rotate,
Inking is performed by a journal ink roller 20.

In the next first printing process, the type wheel spindle ゛' that continues to rotate
R'"C stop ahs Kaede 6゛4 The desired type chips 1o are also aligned and stopped at the first printing position. After that, the journal printing member starts operating,
The desired type chip 1o is pressed and printed on each digit simultaneously through the journal printing paper 2, and the first printing process is completed by returning to the position before operation.

Next, the inking step @2 will be explained. Type wheel spindle 1 again
1 rotates in the direction of the arrow, and the type chips 10 printed in the first printing process rotate in an aligned state and are inked again by the receipt ink roller 21. Then the second
The printing process will be explained. The type wheel shaft 11 stops again, the receipt printing member 5 operates, and the type chips 10 printed in the first printing process are also printed on the receipt printing paper 6.

Finally, to explain the reset process, the type wheel shaft 11 rotates again in the direction of the arrow to select the desired type chip 10.
is returned to the position before rotation by the selection means 12 to 19 and stopped. The type wheel shaft 11 rotates further and is stopped together with the motor by a print end signal issued by the printer. The above is the operation of one print cycle.

As described above, according to the present invention, by taking advantage of the feature that receipt and journal printing are the same in an IOR printer and using selected type for both journal side printing and receipt side printing, the type wheel is smaller than the conventional one. With this, the type wheel selection method is also halved, resulting in a significant cost reduction and the ability to provide a lower-priced ICOR printer. Also, the type wheel 9 and the selection means 12~
16 is half the size of the conventional printer, which has the effect of increasing reliability when selecting parts of the printer, reducing the burden of testing during the design stage, and improving ease of assembly. . In addition, conventionally, the receipt electromagnetic coil and the journal electromagnetic coil are simultaneously energized, resulting in high power consumption, but according to the present invention, the electromagnetic coil is halved, so the power consumption is halved, so the power consumption is significantly reduced. It becomes less.

As described above, the present invention has low cost and high reliability.

It is an EOR printer that achieves low power consumption.
