Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic ticket issuing apparatus using a continuous medium, particularly a roll-shaped continuous medium.

[0002]

2. Description of the Related Art FIG. 2 is a schematic side view showing a prior art of this type of automatic ticket issuing apparatus. In the figure, 1 is a continuous medium, 1'is a roll of the medium 1, 2 is a loading section for loading the roll 1 ', 10 is a printing section for printing on the medium, and the printing section 10 is a thermal head 4 , A platen 5 and an ink ribbon 6. 7 is a cutter as a cutting means for cutting the printed medium 1 into a predetermined length, 8 is a discharge roll for discharging the cut medium, 9 is a discharge port, and 3 and 3'convey the medium to these parts. Along with this, it is a feed roller as a conveyance means for feeding the medium front end backward to the standby position.

Here, in order to print on the medium 1, the feed rollers 3, 3'are driven by a drive source such as a motor (not shown) to pull out and convey the medium from the roll 1 '. Since the load is very large, it takes time to start the transportation. Therefore, the following mechanism is provided to smoothly supply the medium length corresponding to the startup time to the transport system.

That is, 31 is a tension arm, which gives the medium supplied from the roll a slack having a length corresponding to the start-up time of the supply of the roll and also gives a tension to this slack. Reference numeral 32 denotes a tension spring, which pulls the tension arm 31 and resets it to the return position, and also applies an appropriate tension to the tension arm 31.

Reference numeral 23 is a medium cueing sensor, and 24 is a standby position locating sensor, which are provided on the traveling path of the medium. The operation of the conventional example having the above configuration will be described. First, a control unit (not shown) issues an initial command, so that the medium 1 is conveyed to the standby position sensor 23 by the feed roller 3 and waits for a ticket issuing command.

Next, when a ticketing command is issued, the medium 1
Is sent to the printing unit 10 by the feed rollers 3, 3 '. In the printing section, the print timing is set by the medium cueing sensor 23, and the medium 1 is pressed against the ink ribbon 6 by the thermal head 4 and the platen 5 to perform predetermined printing on the surface. At this time, the slack held by the tension arm 31 is fed while the tension spring 32 provides an appropriate tension until the roll supply is started up, so that the medium 1 can be stably transported.

After that, the medium 1 is cut into a predetermined length by the cutter 7 and ejected from the ejection port 9 by the ejection roller 8, and a series of ticket issuing operations are completed. After the ticketing operation is completed, a timer (not shown) is monitored, and if there is no next ticketing command within a predetermined time, it is determined that the ticketing operation is not continuously performed,
The feed rollers 3 and 3 ′ are driven in the reverse direction so that the front end of the cut medium 1 is retracted to the standby position sensor 24.

At this time, the tension arm 31 is reset to the return position by the tension of the tension spring 32.

[0009]

However, according to the prior art having the above-described structure, the medium is always tensioned via the tension arm regardless of the printing standby and the apparatus stop, so that a strong curl curl is generated. Therefore, there is a problem that a trouble such as a jam easily occurs.

In view of the above problems, the present invention provides a structure in which the medium is released from the tension from the tension arm when the medium is stopped for a long period of time such as when waiting for printing or when the apparatus is stopped, and curling is provided. It is an object of the present invention to provide a device which prevents the occurrence of jams and causes less trouble such as jams.

[0011]

In order to achieve the above object, the present invention is designed to slacken a medium in a state where the tension arm does not receive the tension of the tension arm when the medium is stopped for a long time. That is, the present invention provides a loading unit for loading a roll of continuous medium, a printing unit for printing on the supplied medium, a cutting unit for cutting the printed medium to a predetermined length, and a cut medium. A discharge port for discharging, a transporting unit for transporting the medium to each of these parts, and a backward feeding of the medium front end to the standby position, and a slack of a length corresponding to the start-up time of the roll supply to the medium supplied from the roll. In an automatic ticket issuing apparatus having a tension arm for holding and applying tension to the slack, a return detection means for detecting the return of the tension arm and a clearance for allowing the slack of the medium are provided, and the medium tip is waited by the conveying means. In the case of reverse feeding to the position, the reverse feeding of the conveying means is stopped after a predetermined time has passed after the tension arm has completely returned.

[0012]

With the above construction, in the present invention, when the leading end of the medium is fed back to the standby position by the conveying means, the return detecting means detects the return of the tension arm, and the tension arm is returned for a predetermined time. Then, the reverse feeding of the conveying means is stopped, so that the medium is fed into the clearance and a predetermined slack is generated in the tension arm.
