Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dew condensation preventing device for a ticket issuing terminal which reads a mark card with a mark card reading device and prints a ticket with a ticket issuing printer.

[0002]

2. Description of the Related Art In this type of conventional ticket issuing terminal, there is no means for preventing dew condensation in the ticket issuing terminal.

[0003]

Condensation may occur in the ticket-issuing terminal at the first start-up in the morning in a cold region. In conventional ticket issuing terminals, when dew condensation occurs, paper jams occur in the paper transport path of the mark card reader and ticket printer, and paper jams occur due to water drops on the position sensor etc. There was a problem of going out.

Further, when dew condensation occurs on the electric parts, there is a problem that the electric parts are destroyed due to a short circuit.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a dew condensation preventing device for a ticket issuing terminal which can prevent the occurrence of troubles due to dew condensation at the ticket issuing terminal.

[0006]

A dew condensation preventing device for a ticket issuing terminal according to the present invention is made to achieve the above-mentioned object, and a mark card reading device reads a mark card and a ticket issuing printer prints a ticket. In the ticket issuing terminal, a dew condensation sensor is disposed in the ticket issuing terminal and detects dew condensation at the location, a heater provided in the ticket issuing terminal, and the heater if there is a detection signal from the dew sensor. And a control unit for energizing only the main body of the ticket issuing terminal if there is no detection signal.

Further, the control section operates a switch having a contact capable of switching energization to either the heater or the main body of the ticket issuing terminal, and operating the contact depending on the presence or absence of a detection signal from the condensation sensor. And a control circuit that operates.

[0008]

When the dew condensation occurs in the ticket issuing terminal, the dew condensation sensor promptly detects the dew condensation, and the controller starts energizing the heater. At this time, the control unit does not energize the main body of the ticket issuing terminal. Then, the heater is energized to warm the inside of the ticket issuing terminal and the dew condensation disappears. The disappearance of the dew condensation is also detected by the dew condensation sensor, and the controller stops energizing the heater and starts energizing the main body of the ticket issuing terminal.

FIG. 1 is a block diagram of an embodiment of the present invention. Hereinafter, the present invention will be described with reference to the drawings.

The dew condensation preventing device 10 is arranged in the ticket issuing terminal machine 12 and detects dew condensation at the location where it is arranged, and a heater 16 provided in the ticket issuing terminal machine 12.
If there is a detection signal 14a from the dew condensation sensor 14, only the heater 16 is energized, and if there is no detection signal 14a, only the main body 18 of the ticket issuing terminal 12 is energized.
It is equipped with and. Further, the control unit 20 controls the heater 1
Switch 22 having contacts 22b, 22c, 22d capable of switching energization to either one of 6 and the main body 18,
The control circuit 24 operates the contacts 22b, 22c, 22d according to the presence or absence of the detection signal 14a.

The dew condensation sensor 14 is arranged at a place where a trouble occurs due to dew condensation, for example, a paper conveyance path, a position sensor, an electric component, or the like or in the vicinity thereof. The heater 16 is
The dew condensation sensor 14 is provided at or near the location. The switch 22 operates as a relay, and contacts 22b,
22c is fixed, and the contact 22d is movable. The contact 22b is the heater 16, the contact 22c is the main body 18, and the contact 22d is AC.
Each is connected to 100V. The main body 18 is composed of a mark card reader, a ticket issuing printer, etc., which are not particularly shown.

Next, the operation of the dew condensation preventing device 10 will be described.

Before the ticket issuing terminal 10 is started up, that is, before the power is turned on, the contact 22d is not in contact with either of the contacts 22b and 22c, as shown in FIG. If dew condensation does not occur when the ticket issuing terminal 10 is started up,
Since the dew condensation sensor 14 does not output the detection signal 14a to the control circuit 24, the control circuit 24 sets the contact 22d to the contact 22c side and starts energizing the main body 18.

On the other hand, dew condensation may have already occurred in the ticket issuing terminal 10 at the first start-up in the cold district in the morning. In this case, when the ticket issuing terminal 10 is turned on, the dew condensation sensor 14 detects dew condensation and outputs a detection signal 14a to the control circuit 24. The control circuit 24 has a contact 22d
To the contact 22b side to start energizing the heater 16 and not energizing the main body 18. Therefore, since the ticket issuing terminal 10 does not operate at this stage, no trouble due to dew condensation can occur.

After a while, the heater 16 is energized to warm the inside of the ticket issuing terminal 12 and the dew condensation disappears. The disappearance of dew condensation is also detected by the dew condensation sensor 14, and the control circuit 2
4 turns the contact 22d to the contact 22c side to stop energizing the heater 16 and start energizing the main body 18. Here, the ticket issuing terminal 10 operates for the first time.

Even when dew condensation occurs after the ticket issuing terminal 10 is started up, the dew condensation preventing device 10 operates in the same manner as described above.

[0017]

As described above, according to the present invention, the dew condensation sensor detects the dew condensation inside the ticketing terminal and warms it with the heater, and the dew condensation is prevented from energizing the ticketing terminal body. It is possible to reliably prevent the occurrence of a failure due to.
