ことができないという欠点がある。 Conventionally, this type of device has a print head facing the middle of a conveyance path in which an open passbook is held and conveyed by a plurality of pairs of conveyance rollers, and the passbook that is being conveyed is temporarily stopped and then printed by the print head. Some printers are configured to print on predetermined printing lines. However, with this device, when printing, the front and rear pages of the passbook are held down by a pair of conveyor rollers, so the passbook is bent due to the way the pair of conveyor rollers hold down the passbook, and a predetermined print line is printed on the print head. There is a drawback that the printer is misaligned with respect to the area and cannot print accurately on a predetermined print line.

It can be moved back and forth in the direction, and prints along the binding line a of the passbook p. In addition, the above print head 4
A head tip 5 as a pressing member is fixedly attached to the tip of the pressing member, and this is supported by a biasing spring (pressing means) 6.
The urging force presses the vicinity of the periphery of the print area of the passbook p by the printing head 4, and guides the ink ribbon b. That is, the printing head 4 is configured to be movable toward and away from the conveyance path 1 and urged by the biasing spring 6 in the direction toward the conveyance path 1 during printing operation. The head tip 5 can press the bankbook P when the head tip 5 is pressed. The head tip 5 has a substantially U-shaped planar shape and is connected to the print head 4 so as to surround the tip of the print head 4. That is,
This generally U-shaped head chip 5 is connected to the rear side of the print head 4 in the transport direction of the transport path 1 at a part of the inner wall surface of its U-shaped bottom, so that the U-shaped opening side is connected to the print head 4. It is located on the forward side of the head 4 in the conveyance direction of the conveyance path 1 . Further, when the head tip 5 presses the passbook p, a gap corresponding to the stroke of the print head 4 is formed between the print head 4 and the conveyance path 1. When printing near the binding line a of the thin side page of the bankbook p, the area near the binding line a of the thin side page of the bankbook p as well as the vicinity of the binding line of the thick side page is pressed. Further, the ink ribbon b is inserted between each of the U-shaped parallel parts 7, 7 and the print head 4, and the ink ribbon b is inserted between the print head 4 and the passbook p and along the width direction of the conveyance path 1. It is designed to guide you to run the car. The head tip 5 also has a wide ink ribbon b, for example, an ink ribbon b slightly wider than twice the effective printing width of the printing head 4.
One end side from the center in the width direction is the print head 4.
It is designed to guide the user to a state where they are facing each other.

うになつている。 Further, the printing mechanism 3 has an anvil (supporting member) 8 on the opposite side of the printing head 4 with respect to the transport path 1. This anvil 8 is arranged along the width direction of the conveyance path 1, and
It has a shape in which the conveyance path 1 side, which has a circular cross section, is cut out along the conveyance path 1. The notch 9 supports the back side of the printing part of the bankbook p by the printing head 4. Furthermore, wedge-shaped escape parts 11, 11 are formed between the circular arc surface parts 10, 10 near both ends of the notch part 9 and the conveyance path 1, for allowing the passbook p pressed by the head chip 5 to escape. That is, when printing near the binding line a of the thinner page of the passbook p, the relief parts 11, 11 are used as the head tip 5.
The thicker page side of the passbook P, which is pressed by the user, will be missed. The conveyance mechanism 2 is disposed to constitute the conveyance path 1, and the first conveyance mechanism 2 constitutes the rear side of the conveyance path 1 from the printing head 4 in the conveyance direction.
a second conveying body 1 constituting the forward side of the conveying path 1 from the printing head 4 in the conveying direction.
It is composed of 3. The first carrier 12
is the first driving roller 1 that supports the cover side of the passbook p.
4, and the conveyance path 1 is connected to this first drive roller 14.
and a first pinch roller 15 that is separably in contact with the first pinch roller 15 via the first pinch roller 15. The second transport body 1
3 is composed of a second drive roller 16 that supports the cover side of the passbook p, and a second pinch roller 17 that rolls into contact with the second drive roller 16 via the conveyance path 1 so as to be able to separate from the second drive roller 16. . These first and second pinch rollers 15 and 17 are rotated by known means such as a rotatable arm to which these rollers 15 and 17 are attached, a biasing spring, and a plunger. It is configured to be able to be evacuated independently from the previous page or the next page of the bankbook p, and the evacuation from the bankbook p is controlled according to the number of lines to be printed on the bankbook p. That is, as shown in FIG. 2, when printing on the rear page of the bankbook p, the first pinch roller 15 presses the rear page of the bankbook p against the first drive roller 14, and the second pinch roller 17 presses the rear page of the bankbook p. is separated from the second drive roller 16 and retracted from the previous page of the passbook p. Also, as shown in Figure 3, when printing the previous page of the passbook P, the second
The pinch roller 17 presses the previous page of the bankbook p against the second drive roller 16, and the first pinch roller 15 presses the previous page of the passbook p against the first drive roller 1.
4 and is evacuated from the back page of passbook p.

クリボンbで行なうことができる。 However, when printing on passbook p,
Hold down the printed page of the previous and next pages,
Keep non-printing pages free. Therefore, the bankbook p is not warped, the predetermined print line of the bankbook p can be accurately set in the print area of the print head 4, and the predetermined print line can be printed with high precision. Furthermore, when printing near the binding line a of the thinner page of the passbook p, the edge a of the bankbook p is pressed against the anvil 8 by the head chip 5, and the vicinity of the binding line a of the thicker page is printed on the relief part 1.
1, it is possible to eliminate the step formed by the thin side page and the thick side page at the binding line a of the passbook p. At this time, since the thick side page is held in a free state, the vicinity of the binding seam a of the thick side page of the passbook p can be easily inserted into the relief part 11, and the predetermined printing line of the passbook p may be misaligned with the printing area of the print head 4. It is possible to escape without causing any bumps, and the level difference can be effectively eliminated. Therefore, even if a wide ink ribbon b is used, it is possible to print near the binding line a of the thin side page of the passbook P without the ink ribbon b touching the vicinity of the binding line a of the thick side page of the passbook P and causing stains. . Furthermore, by using a wide ink ribbon b, not only can the ink ribbon b be formed into a Möbius ring shape and the life of the ink ribbon b can be extended, but also multicolor printing such as red and black can be performed with the same ink ribbon b. Can be done.

い。 In addition, in this embodiment, the conveyance mechanism 2 was configured by a plurality of rolls 14, 15, 16, and 17.
The present invention is not limited to this, and may be constructed using a belt, for example, and it goes without saying that the conveyance mechanism 2 only needs to be able to retreat independently from the front page or the rear page of the booklet p in the conveyance path 1. . Furthermore, in this embodiment, the relief portion 11 is provided on the anvil 8, but the present discussion is not limited to this, and the relief portion 11 may be provided on the head tip (pressing member) 5.
