Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus for printing on a passbook, a slip or the like having seals and revenue stamps attached thereto, and a line feed method thereof.

[0002]

2. Description of the Related Art Conventionally, a printing apparatus for printing on a passbook, a slip, etc., selects a print head gap for a print sheet from a print gap storage means and sets it by a head gap changing mechanism under the control of a print control means. The printing head performs a spacing operation in the line direction of the printing paper by the spacing mechanism to print by the printing mechanism, and the printing paper feeds by the line feed mechanism.

[0003]

In the conventional printing apparatus, if a seal / income stamp or the like is attached to a passbook or a slip at the line feed position, the front end surface of the print head and the printing paper surface are The gap is narrower than the print head gap, which causes a load, does not feed the line feed normally, and causes printing misalignment. Even if a seal or revenue stamp is attached to a passbook or slip. There has been a demand for a printing apparatus and a method for feeding the line feed by providing a sufficient head gap between the print head and a seal or revenue stamp.

[0004]

In order to solve the above problems, in the present invention, the line feed head gap value is stored.
Attach line break gap storage means and stickers, revenue stamps, etc.
When performing a print operation on a print sheet that has a line break prohibited area, which is an area, before the line break operation is performed, it is determined whether the print head is in the line break prohibited area and it is judged that the print head is in the line break prohibited area. In some cases, change from the line feed gap storage means.
The line head gap value is read out, and after the print head gap is widened, a line feed management means is provided for performing a line feed of the printing paper.

[0005]

The line feed management means of the printing apparatus configured as described above is provided when the print head is in the line feed prohibited area.
After widening the print head gap, the line feed is performed by the line feed mechanism.

[0006]

Embodiments of the present invention will be described with reference to the drawings. Elements common to the drawings are given the same reference numerals.

First Embodiment FIG. 1 is a functional block diagram of the first embodiment. The print control means 1 reads the print head gap for the print paper from the print gap storage means 2, sets it by the head gap changing mechanism 3, and causes the print head to perform a spacing operation in the row direction of the print paper by the spacing mechanism 4. When the line feed control means 6 inputs a line feed signal from the print control means 1, the print head position data is input and compared with the contents of the line feed prohibited area storage means 7, and the print head feeds a line feed. If it is in the prohibited area, the line feed head gap value is read from the line feed gap storage means 8, the head gap changing mechanism 3 widens the head gap, and the line feed mechanism 9 starts a line feed. The line feed management means is composed of a line feed control means 6, a line feed prohibited area storage means 7, and a line feed gap storage means 8 surrounded by a dashed line.

FIG. 2 is a schematic diagram showing the operation of the printing apparatus of the first embodiment. The print head 10 has a print head gap facing the platen 11, and prints by performing a spacing operation in the direction of arrow AB which is the row direction of the print paper 12. When the print head 10 performs the printing operation from the line start character position 13 to the line end character position 14, for example, the spacing operation is stopped, and the printing paper 12 is fed in the direction of arrow C. The platen 11 moves in the direction of arrow D-E with respect to the print head 10 to change the head gap .
It

By the way, a seal, a revenue stamp, etc. are attached to the printing paper 12, and in that area, the gap between the front end surface 10a of the printing head 10 and the printing paper 12 is narrower than the printing head gap, which becomes a load. Since the line feed is not normally performed and there is a risk of printing misalignment, the region where the seal or revenue stamp is attached is defined as the line feed prohibition region 15. FIG. 3 is a control block diagram showing the control configuration of the first embodiment. The central processing unit 21 (hereinafter referred to as CPU 21) has a memory 22 (hereinafter referred to as MEM 22) and an input / output device 23.
(Hereinafter referred to as I / O 23) are connected via a bus line.

The spacing motor 28 receives a drive signal from the CPU 21 and moves a carriage (not shown) on which the print head 10 is mounted, in the directions of arrows AB shown in FIG.

The line feed motor 29 feeds the print sheet 12 in the direction of arrow C shown in FIG. 2 through a line feed mechanism (not shown) based on a line feed signal from the CPU 21.

The print head 10 inputs a print timing signal and print data from the CPU 21 and prints on the print paper 12.

The head gap setting motor 30 is the CPU 2
1 to input a drive signal to rotate the platen 11 through a head gap mechanism (not shown), and the arrow D- shown in FIG.
Move in the E direction.

The MEM 22 stores a control program and data, and print data and line data are stored as the data.
Data, a line feed prohibited area data, a print head gap value according to the print paper 12, a line feed head gap value for moving the platen 11 at line feed in the direction of arrow E, and the like. The line data is the number of characters from the line start character position 13 to the line end character position 14, and the line feed prohibited area data is the distance F, G in the direction of arrow B from the line start character position 13 to the line feed prohibited area 15. Is.

FIG. 4 is a flow chart showing the printing operation for one line.

Next, the operation will be described with reference to FIG.

In step S1, the CPU 21 inputs print data and line feed prohibition data from the host device and stores them in the MEM 22 .

In step S2, the CPU 21 reads the print head gap value corresponding to the print sheet 12 from the MEM 22 and drives the head gap setting motor 30 to determine the head gap.

In step S3, the CPU 21 reads the print data, the line data, and the line feed prohibited area data from the MEM 22 and starts the print operation while setting the print timing.

In step S4, the CPU 21 starts a line feed operation.

In step S5, the CPU 21 controls the print head 1
It is checked whether 0 is in the line feed prohibited area 15.

In step S6, the CPU 21 sets the value H = 0 at the line start character position 13 to the value H = H + 1 which is incremented by +1 every time one character is printed.
The print position data J = H × I obtained by multiplying by is compared with the distance F which is the line feed prohibited area data. When F ≦ J ≦ G, the line feed head gap value is read from the MEM22. The head gap setting motor 30 is driven to move the platen 11 in the arrow E direction.

In step S7, the CPU 21 causes the line feed
The printing paper 12 is fed by line feed in the direction of arrow C shown in FIG.

If step S5 returns NO, step S7
Proceed to.

[0026] In this embodiment by entering a line feed signal, spread the head gap, by providing a new line management means for performing a new line feed, there by attaching the seal revenue stamp or the like to the line breaks, such as through books and documents even line breaks feed well provided the head gap between the print head and the seal revenue stamp or the like can rows Ukoto, never causing a printing deviation or the like, print quality is improved.

Further, since it is checked whether or not the print head is in the line feed prohibited area before line feed, the sticking position of the seal, the revenue stamp, etc. is not limited.

Second Embodiment FIG. 5 is a functional block diagram of the second embodiment. The print control means 1 reads the print head gap for the print paper from the print gap storage means 2, sets it by the head gap changing mechanism 3, and causes the print head to perform a spacing operation in the row direction of the print paper by the spacing mechanism 4. When the line feed control unit 6 inputs a line feed signal from the print control unit 1, the line feed head gap value is read from the line feed gap storage unit 7, and the head gap changing mechanism 3 widens the head gap and feeds a line feed. Mechanism 9
