Abstract

PURPOSE:To securely print at a predetermined position of a slip, by a method wherein the first and second skew-detecting sensors for detecting a skew of a slip are provided at predetermined positions of a pocket for supporting a slip in a slip inserter. CONSTITUTION:When the slip 10 is fed out in a leftwardly skewed condition, a slip-detecting sensor 13 detects a trailing end part of the slip 10, upon which each of detection signals 20S, 21S from the skew-detecting sensors 20, 21 is brought into an OFF-condition. Namely, a detection logical circuit 30 informs a printer-driving circuit 31 of the detection of the skew of the slip 10 by a detection signal D, whereby the circuit 31 is so operated as to stop a printing operation. On the other hand, when the slip 10 is fed out in a rightwardly skewed condition, the skew detection signals 20S, 21S are brought into an ON- condition when a signal 13S from the sensor 13 is in an ON-condition, and in this case also, the circuit 31 is operated to stop the printing operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a ticket inserter used in printers and the like.

[Technical background of the invention and its problems]

In general, a printer or the like is provided with an inserter for feeding a cut to be printed to a printing section. Such an inserter is generally constructed as shown in FIG. That is, as shown in FIG. 1(5), the inserter has left and right pockets 112. which hold the cut sheet 10 in a vertical position. Il
It is equipped with b. The left and right pockets 11a and 11b are configured to be movable in the left and right directions according to the size of the cut sheet 10.

By the way, when the tips of the tickets 10 set in the pockets 11a and 11b are caught by the feed rollers 12a and 12b, they are sent out, for example, downward (in the direction of the arrow of the first prisoner), and are sent to, for example, a printer. The paper will be fed to the printing section. In this case, a detection sensor (for example, a photoelectric sensor) 13 for detecting the rear end of the ticket 10 is provided at a predetermined position of the left pocket 11a, for example.
It is detected that the cut sheet 1o has been sent out, and the feed roller 12a is moved.

The drive of 2b will be stopped.

However, with such a conventional inserter, for example, when inserting the cut sheet 1o into the pockets lla and zzb, a setting operation error l is caused by the left and right feed rollers 12a and 12b.
Due to reasons such as differences in the timing of inserting into
).

When the ticket 10 is sent to a printing unit of a printer in such a tilted state (skew), there is a drawback that the ticket 10 is not printed at a predetermined printing position.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to prevent a cut from being sent out to a printing unit in a tilted state in a printer, etc. To provide a slip inserter that can print reliably.

[Summary of the invention]

According to the present invention, first and second skew detection sensors for detecting the skew (inclination) of a ticket are provided in a predetermined position of a pocket that holds the ticket in a ticket inserter used in a printer or the like. The first skew detection sensor is installed in an upright position such that it detects the rear end of the cut sheet before the rear end of the cut sheet is detected μ by the cut sheet detection sensor.

Further, the second skew detection sensor is arranged in advance at a distance from the first skew detection sensor in the traveling direction of the cut sheet according to a skew detectable range.
It is provided at a position such that the rear end of the cut sheet is detected after the rear end of the cut sheet is detected. As a result, a ticket sent out in an inclined state can be reliably detected, and based on the detection result, printing operations on the ticket can be stopped.

[Embodiments of the invention]

An embodiment ζ of the present invention will be described below with reference to the drawings. FIG. 2 shows the configuration of a cut inserter according to the present invention, and 20.21 is a skew detection sensor (for example, a photoelectric sensor) for detecting the skew (inclination) of a cut 10.
For example, it is provided at a predetermined position on the right pogget IIb.

In this case, the ticket detection sensor 3 for detecting the rear end portion 22 (with respect to the traveling direction of the arrow) of the ticket 1o is provided at a predetermined position, for example, in the left pocket IIa. In the skew detection sensors 20 and 21, one sensor 2o is arranged at a predetermined position such that it detects the rear end 22 of the ticket 10 before the rear end 22 of the ticket 10 is detected by the ticket detection sensor 13. be done. Further, the other sensor 2o detects the rear end 22 at a distance g in the traveling direction from the one sensor 2o, and after the rear end 22 is detected by the cut sheet detection sensor 13. It is placed in a position where it can be detected. The distance l is determined according to a preset skew detectable range. In addition, in Fig. 2 (8),
23 is the support section of the inserter body, and 24 is the feed roller 12.
a, is the drive shaft of No.2b, and is also the drive shaft of No.2b in the same figure (Bl).
5 is a pleasure roller. Components that are the same as those in FIG.

In such a configuration, the operation will be explained with reference to FIGS. 3 and 4. For now, the left and right pockets lla,
The cut sheet 10 is set on Ilb, and the feed roller 12a,
By driving 12b, the cut sheet 1o is sent out, for example, in a downward direction. In this case, the rear end of the ticket 10 is detected by the ticket detection sensor 13 (detection signal 13S).

After a certain period of time, the feed rollers 12a and 12b stop driving, and the feed operation is stopped. At this time, as shown in Figure 3 (Al
As shown in the figure, one skew detection sensor 20 detects the rear end of the single sheet 1o (detection signal 2oS), and the other skew detection sensor 2I is in the OFF state (that is, the rear end of the single sheet lθ is not detected). (detected), it means that the ticket 1o was sent out in a normal state. In this case, each sensor IJ, 20 is connected to a detection logic circuit 30 as shown in FIG.
, 21 and 21, respectively, the detection logic circuit 30 outputs the detection signals to, for example, the printer drive circuit 3. As a result, the printer drive circuit 3 performs a printing operation and prints at a predetermined printing position on the cut sheet 10. Here, the detection logic circuit 30 includes one, for example, AND circuits 32a, 32b, and an inverter 33, and a detection signal 1 is input to each input terminal of the AND1 circuit 32H.
ss and zos are given, and a detection signal 2z8 is given to the input terminal of the inverter 33. Furthermore, each output signal of the AND circuit 32a and the inverter 33 is applied to each input terminal of the AND circuit 32b.

The AND circuit 32b is configured to output a detection signal.

Here, as shown in FIG. 3 (131), when the ticket 10 is fed out tilted to the left, the ticket detection sensor 13 detects the rear end of the ticket 10 (the signal 13S is in the ON state). ), each detection signal 208 of the skew detection sensors 20 and 21
, 218 are both turned off. That is, the detection logic circuit 3
0 instructs the printer drive circuit 31 to detect the skew of the cut sheet 10 using the detection signal D (eg, signal "O").

As a result, the printer drive circuit 3 operates to stop the printing operation. Furthermore, when the cut sheet 10 is fed out with an inclination to the right as shown in FIG. , 218 are both turned on. In this case as well, the printer drive circuit 31 stops the printing operation in response to the detection signal D(ro'' of the detection logic circuit 30), as described above.

In addition, in this case (in the case of Fig. 3 (Bl, (C)),
Due to the detection signal of the detection logic circuit 30, the feed roller 12
Single sheet 1 tilted with the rotation direction of a and 12b reversed
0 may be ejected from pockets lla and llb.

In this way, when the ticket detection sensor 13 detects the rear end of the ticket 10, it can be detected that the ticket IO is fed out in an inclined state, according to the detection results of the skew detection sensors 20 and 21. It can be detected reliably. In this case, the range in which the skew of the cut sheet 10 can be detected is as follows:
1 will be set corresponding to each position.

Therefore, when the ticket 10 is sent out in an inclined state, the printing operation of the printer can be stopped, and the ticket 10 can be placed in the pocket 112. It can also be discharged from Ilb. Thereby, inconveniences such as printing at a position other than the predetermined printing position μ on the ticket 10 can be reliably prevented.

〔Effect of the invention〕

As described in detail above, according to the present invention, in a ticket inserter used in a printer or the like, it is possible to reliably detect a ticket whose inclination is outside the permissible range when the ticket is sent out. Therefore, it is possible to prevent the ticket from being sent out to the printing section of the printer in a tilted state. As a result, for example, a predetermined printing position μ
It can prevent printing on the outside and realize reliable printing operation against single sheets.
