[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a thermal transfer recording machine having a function of passing a recording paper, which has a sub-scanning direction longer than a standard paper, capable of fully printing a paper surface area, through a printing device, and cutting the recording paper into a standard paper size by a cutter after printing.

[0002]

[Prior Art]

 A wide variety of thermal transfer recording machines are known, but printing can be performed by passing a recording paper through the printer that has a sub-scanning direction longer than the standard recording paper that can fully print the paper surface area of the recording paper. The following is a conventional example of a device that cuts a standard paper size with a cutter and discharges it.

FIG. 3 is a cross-sectional view of ejecting a recording sheet of a conventional example. As a constitution, first, the ink sheet 1 is wound from the ink sheet supply roll 2 to the take-up roll 3 at each end of the winding start portion and the winding end portion of the ink sheet 1, and the ink sheet supply roll and the winding roll 2 are wound. The shafts 3 and 3 are respectively supported by a body frame (not shown). Meanwhile, the thermal head 4 is axially supported by a driving device (not shown) so as to be vertically movable on an upper frame (not shown).

A platen roller 5 is located below the thermal head 4 so as to sandwich the ink sheet 1 and is pivotally supported by a body frame (not shown). A paper feed roller 6 is located on the right side of the platen roller 5, and a capstan roller 7, a cutter 8 and an ejection roller 9 are located on the left side of the platen roller 5, which are axially supported by a body frame (not shown). A guide 11 for smoothly advancing the recording paper 10 is pivotally supported on a body frame (not shown). On the left side of the discharge roller 9, a strip that is discharged after a recording paper longer than a standard size is cut by a cutter and a discharge tray 12 that receives the standardized recording paper by this cut are fixed to a body frame (not shown). It has become. Hereinafter, the excess cut-off portion will be referred to as a strip of paper.

To explain a simple operation, first, when the paper feed roller 6 rotates the recording paper 10 fed from a paper tray (not shown) by a driving means (not shown), the pinch roller a1 3 follows the paper feed roller 6, The weight causes the recording paper 10 to be slid and guided over the guide 11 between the platen roller 5 and the ink sheet 1. After that, when the print sensor 14 senses the leading edge of the recording paper 10, the recording paper 10 is sent to above the capstan roller 7, and the rollers are temporarily stopped by a control device (not shown). Then, the thermal head 4 is lowered onto the platen roller 5, and the ink sheet 1 and the recording paper 10 are sandwiched between the both, and printing is started by signal control (not shown). At that time, each time printing is performed, the ink sheet 1 is wound up by the ink sheet winding roll 3, and the recording paper 10 is sent out to the discharge roller 9 side by the rotation of the capstan roller 7 and the pinch roller b15. Such an operation is repeated for the required printing period.

Next, when printing is completed, when the discharge sensor 16 senses the leading edge of the recording paper 10, the recording paper 10 is sent to above the discharge roller 9. Then, the rollers are temporarily stopped again. Here, between the capstan roller 7 and the discharge roller 9, the recording paper 10 is stretched by the pinch roller b15 and the pinch roller c17 acting on the rollers 7 and 9, respectively, and the discharge sensor 16 cuts the cutter. The recording paper 10 in the portion judged to be the excess length on the left side of 8 is cut around the cutter rotation shaft 18 by rotating the blade edge 19 of the cutter 8 clockwise by a driving device (not shown). The cutter 8 immediately cuts the recording paper 10 and then immediately rotates the blade edge 19 counterclockwise to restore it. After that, when the discharge roller 9 is rotated counterclockwise by a driving means (not shown), the strip paper separated from the original recording paper is sent to the discharge tray 12 side by the weight of the pinch roller c17 which follows this. Then, the stylized recording paper is sequentially sent out.

[0007]

[Problems to be solved by the device]

 However, in the structure of this discharge tray 12, when several sheets of recording paper 10 are continuously printed and discharged, whether the strip paper and the standardized recording paper are overlapped and discharged one after another, or in order to avoid it In addition, there is a problem in that two discharge ports are provided such that only the recording paper is guided to another discharge port by a complicated circuit or a complicated mechanism.

[0008]

[Means for Solving the Problems]

 Therefore, in view of the above, the present invention provides a lever provided on a cutter and its lever when discharging a strip of paper after printing and cutting a recording paper whose sub-scanning direction is longer than a standard recording paper that requires full printing. Provide a recording paper receiving device of a thermal transfer recording machine that automatically separates recording paper and strip paper printed by a member configured in a discharge tray that operates by swinging and discharges from one discharge outlet.

[0009]

[Action]

 With the discharge tray configured as described above, the strip paper and the recording paper do not overlap each other and are not discharged, and a complicated circuit or a complicated mechanism does not require a separate discharge port. In the same way as the above, the strip paper and the recording paper can be separately discharged from one discharge port.

[0010]

【Example】

 The recording paper receiving device of the thermal transfer recording apparatus of the present invention will be described below with reference to embodiments. FIG. 1 is a cross-sectional view of the present invention, and the construction and operation up to printing are the same as those of the conventional means, and therefore will be omitted here. Here, the state before cutting the recording paper 10 with the cutter 8 after printing is shown. That is, the blade edge 19 of the cutter 8 is separated from the recording paper 10 and the recording paper 10 can be moved to the paper discharge roller 9 side. Here, there is an extra cut-off portion of the recording paper 10, that is, a strip of paper, from the cutter 8 to the discharge roller 9 side.

First, the configuration will be described. A lever 20 is fixed to a rotary shaft 18 of a conventional cutter 8 by screwing or the like (not shown). On the side of the discharge tray 12, the recording paper receiver is separated into an inclined side and a flat side, and the recording paper receiving surface a21, which is the inclined side, has a large length in the sub-scanning direction of the recording paper and has a predetermined recording paper size. A receptacle 22 for receiving only the strip paper, which is an extra portion formed by cutting with the cutter 8, is formed by integral molding. The flat recording paper receiving surface b23 functions to receive the recording paper 10 like a conventional discharge tray, and a strip storage unit 24 for stocking the strip paper flowing from the receiving opening 22 of the recording paper receiving surface a21 is integrally provided at the lower portion. A rotary shaft 25, which is formed by molding and rotates and supports the recording paper receiving surface a21 only at a certain angle, is formed at one end thereof.

The recording paper 10 on which printing has been completed is sent to the left by the action of the pinch roller 15 driven by the capstan roller 7 which is rotated counterclockwise by a driving device (not shown), and passes through the cutter section 8. Then, when the leading edge of the recording paper 10 is detected by the discharge sensor 16, when it is further fed to the left and reaches the discharge roller 9, the controller, not shown, stops the rotation of the capstan roller 7 and the discharge roller 9, The feeding of the paper 10 is also stopped.

FIG. 2 is a cross-sectional view of the operation when the cutter 8 of the present invention cuts the recording paper 10, and the operation will be described here. As before, the recording paper 10 is stretched between the capstan roller 7 and the discharge roller 9 because the pinch roller b15 and the pinch roller c17 act on the rollers 7 and 9, respectively. The cutter 8 rotates in the clockwise direction by the action of a driving device (not shown), the cutting edge 19 contacts the recording paper 10, and the portion on the left side of the cutter 8 that is judged to be the extra length, that is, the strip paper is cut. At that time, the cutter 8 stands by at a position where the cutting edge 19 has descended unlike the conventional case. At the same time, the lever 20 pivotally supported by the rotary shaft 18 of the cutter 8 rotates clockwise, and its tip rotates counterclockwise about the rotary shaft 25, lifting the recording paper receiving surface a21 and opening the receiving port 22. Guide it onto the discharge roller 9.

While maintaining this state, first, the discharge roller 9 rotates counterclockwise to guide only the strip paper from the receiving opening 22 into the strip storage portion 24. After that, when the discharge sensor 16 senses that the strip has run out, the blade edge 19 of the cutter 8 is rotated counterclockwise to form the passage of the recording paper 10, and the tip of the lever 20 also moves to the recording paper receiving surface a21. Cancel the action and return to the original state of FIG.

Therefore, the recording paper receiving surface a21 returns to the initial state, and thereafter, the capstan roller 7 and the discharge roller 9 rotate in the counterclockwise direction as in the conventional case, and the stylized recording paper 10 is placed on the recording paper receiving surface a21. It is discharged via the recording paper receiving surface b23.
