Description

DETAILED DESCRIPTION [Outline] A device used in a cold region is connected to a power supply of a system different from the power supply for driving the device, and the device is installed in close contact with a specific equipment unit forming the device. Temperature sensor, a heater closely attached to the lower part of the specific device unit,
Also, a heater unit including a temperature controller that automatically controls the heater is provided so that the temperature indicated by the temperature sensor reaches a specified value, and the heater unit is operated regardless of whether the apparatus is powered on or off.

[Industrial application field]

The present invention relates to a terminal device, and more particularly, to a heater unit of the terminal device used in a cold region.

[Conventional technology]

Cash handling devices such as cash dispensers have recently become widely used.

When these cash handling devices are used in cold districts, when the outside air temperature drops extremely, the devices, especially the banknote transport mechanism, the card transport mechanism, and the moving parts such as the passbook transport and page feed mechanism, etc. The temperature may drop and it may not function properly. For example, it may happen that the transport roller does not operate with the set motor torque, and for this reason, it is widely practiced to provide a heater unit in the apparatus to keep the temperature inside the apparatus constant.

[Problems to be solved by the invention]

However, in the device using the conventional heater unit,
Since the drive power of the heater unit is turned off when the night unit is not used, the problem that the malfunction of the mechanical unit due to the squeeze of the mechanical unit and the trouble such as dew condensation occur when the device is turned on the next morning. It was

[Means for solving problems]

The above problem is caused by connecting a device 10 used in a cold region to a power source of a system different from the power source for driving the device 10 as shown in the principle diagram of FIG.
Temperature sensor 6 and equipment unit 10a installed in close contact with
A heater unit including a heater 7 ₁ which is closely attached to the lower part of the heater and a temperature controller 5 which automatically controls the heater 7 _{1 so} that the indicated temperature of the temperature sensor 6 reaches a specified value is provided. It is solved by operating regardless of the power-on / off state of the power supply.

[Action]

In accordance with the present invention, the specific equipment units that make up device 10.
As indicated temperature of the temperature sensor 6 installed in close contact with the 10a becomes a predetermined value, always identified regardless of whether device 10 the temperature controller 5 automatically controls the heater ₇₁ always is running It is possible to keep the temperature of the device unit 10a of the above at a specified value.

〔Example〕

 FIG. 2 is a diagram showing an embodiment of the present invention.

FIG. 3 is a diagram showing an embodiment of the heater unit.

In the figure, 1 is a heater unit according to the present invention, 2 is a power switch, 3 is a fuse, 4 is a neon lamp, 5 is a temperature controller, 6 is a temperature sensor, 7 ₁ and 7 ₂ are heaters, 7 a is a thermostat, 7b is a seat heater, 7c is a temperature fuse, 10
Is a device, and 10a, 10b, 10c, and 10d are constituent units, respectively. The same symbols represent the same objects throughout the drawings.

As shown in FIG. 3, the heater unit 1 according to the present invention comprises a power switch 2, a fuse 3, a neon lamp 4, a temperature controller 5, a temperature sensor 6, and a plurality of heaters 7 ₁ , 7 _2, etc. . The heaters 7 ₁ and 7 _{2 each} include a thermostat 7a, a seat heater 7b, and a temperature fuse 7c.

The device 10 is a device whose temperature is to be controlled, and has a plurality of constituent units, for example, constituent units 10a, 10b, 10 inside the device.
c, 10d, etc. are implemented.

As an example, the constituent unit 10a is a bill counting unit, and the constituent units 10b, 10c, and 10d are electronic control units, respectively.

In the present invention, the power source for driving the device 10 and the power source for driving the heater unit 1 according to the present invention are separate systems, and the power switch 2 is turned on to turn on the heater unit 1 regardless of whether the device 10 is in the power-on state. To always operate.

The heater unit 1 constantly monitors the temperature of the place where the temperature sensor 6 is installed by the temperature sensor 6, and the temperature detected by the temperature sensor 6 is a prescribed temperature T-for example, minus 10
When the temperature becomes lower than C-, the temperature controller 5 is operated by the seat heater 7b.
To raise the temperature in the device 10, and the temperature sensor 6
When the temperature detected by is higher than the specified temperature T, the temperature controller 5 turns off the seat heater 7b to lower the temperature in the apparatus 10, and repeats the operation as described above, and the temperature sensor 6 is installed at a place where the temperature sensor 6 is installed. Keep the temperature at the specified value.

Although two sets of heaters are installed in FIGS. 2 and 3, one set or a plurality of sets may be used. The thermostat 7a for the heaters 7 ₁ and 7 ₂
The temperature fuse 7c is a safety device for preventing overheating of the seat heater 7b, and prevents a fire or the like due to abnormal overheating even when the temperature sensor 6 is broken.

Generally, in cash handling equipment, the target equipment that must be monitored for temperature drop is the rotation mechanism part where grease oil is used, and if the temperature of the grease oil itself drops due to the ambient temperature drop, its operation May not work properly and may not operate normally. Further, since the power is turned off in the middle of the night, when the power of the device 10 is turned on in the morning, there is a possibility that a malfunction due to the tightness of the mechanical unit and a trouble due to dew condensation may occur. Therefore Taking apparatus 10 shown in FIG. 2 as an example, since the bill counting unit 10a is particularly subject to temperature monitoring, and placed in close contact with the temperature sensor 6 to the bottom of the printer head unit 10a, the bill of the heater 7 ₁ It is installed in close contact with the bottom of the counting unit 10a.

Note installing the heater 7 ₂ in front lower portion of the apparatus 10 as an element for uniformly heating the interior of the apparatus 10.

As described above, the heater 7 ₁ , the heater 7 ₂ and the temperature sensor 6 are connected to the device 10
By installing it inside, whether or not the device 10 is in operation (whether or not the device 10 is powered on),
The temperature controller 5 can always keep the temperature of a specific device unit, for example, the bill counting unit 10a, at the specified temperature T.

〔The invention's effect〕

As described in detail above, according to the present invention, when the morning cash handling apparatus is powered on, there is a great effect that there is no risk of malfunctions due to the mechanical unit squeezing and failures such as dew condensation. .
