In the above-described conventional paper sheet transport apparatus, the torque required for drive rotation in a low-temperature atmosphere is large, and the amount of current must be increased more than usual. Since the operation as in the conventional example is performed until the speed reaches the reference value, it takes a long time.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of a paper sheet transport device according to an embodiment of the present invention. The transport path 1 sandwiches the paper sheets 2 and transports the paper sheets 2 in a predetermined direction. The prime mover 4 is connected to the transport path 1 and drives the transport path 1 in a predetermined direction by rotating. In the prime mover 4, the larger the amount of current, the larger the rotational torque. The current regulator 5 is connected to the prime mover 4 and the power source 6 and supplies the prime mover 4 with a current amount set by the control unit 10. The temperature sensor 9 measures the outside air temperature of the paper sheet transport device, and provides temperature information to the control unit 10. The control unit 10 instructs starting and stopping of the prime mover 4. The control unit 10
Determines an appropriate amount of current from the temperature information of the temperature sensor 9, and controls the current regulator 5 so that the amount of current is given to the prime mover 4.
Set the amount of current. The conveyance path speed measuring device 3 measures the speed of the conveyance path, and provides speed information to the control unit 10. Timer 8
Can be started and stopped by the control unit 7 and give time information to the control unit 10.

FIG. 4 shows the configuration of the control unit 10. Control unit 1
0 indicates the CPU 12 and the RO in which the control program is stored.
M11, a RAM 14 serving as a work area of the program,
O port 13. The CPU 12 reads a program from the ROM 11 and performs control.

FIG. 6 shows the flow of a program stored in the ROM 11. The operation will be described with reference to FIG.

The control unit 10 has three types of current values for each set temperature in the current regulator 5. The three values are a current amount A when the outside air temperature is equal to or higher than a ° C., a current amount B when the external air temperature is lower than a ° C. and higher than b ° C., and a current amount C when the external air temperature is lower than b ° C. A <B for A, B, C, a, b
<C, a> b. The controller 10 determines a current amount to be set in the current regulator 5 based on the temperature value of the temperature sensor 9.

[0014] Now, the outside air temperature of the paper sheet conveying device is b ° C or less.
When the temperature is between a ° C., the control unit 10 sets the current value B in the current regulator 5 and starts the prime mover 4. The control unit 10 activates the timer 8 at the same time as activating the prime mover 4, and measures the time. The control unit 10 monitors whether the transport path speed measured by the transport path speed measuring device 3 becomes equal to or higher than the specified transport path speed at the false output interval.

[0015]

As described above, according to the present invention, the optimum amount of current to be applied to the prime mover that drives the conveying path is immediately determined by measuring the temperature of the atmosphere of the sheet conveying apparatus. This has the effect that the time required for the speed to reach the reference value is as short as possible.
