Abstract

PURPOSE:To prevent an increase of jamming of paper and a damage of paper by providing a memory means to store the jamming data to indicate under which sensor the jamming is generated, and a means to decide the drive or nondrive of a conveying route referring to the jamming data stored in the memory means. CONSTITUTION:When a jamming is generated under a C sensor 10 on a conveying route 6 during the conveying operation, a controller 2 stops the conveying route 6, and an information that a jamming is generated under the C sensor 10 is stored in a RAM backed up by a battery. The operator removes the papers generating the jamming from the conveying route 6, and makes an operating member 1 instruct to clear the conveying route 6. And when the controller 2 receives the instruction to clear the conveying route from the operating member 1, the controller 2 reads the data of the place of the sensor 10 when the jamming is generated from the RAM backed up by a battery, and after checking it with a sensor, the controller 2 checks whether there is paper or not under the sensor 10 which has generated the jamming.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a paper sheet conveying device, and is particularly used in automatic teller machines, etc., to reduce the effects of jams (prior art). In the conveyance device, when a jam occurs under the sensor on the conveyance path, the conveyance path is activated unconditionally by the operator's operation, or when all sensors do not detect a sheet, and the conveyance path is cleared. I was going.

(Problems to be Solved by the Invention) In the conventional sheet conveying device described above, when clearing the conveying path, if the conveying path is started unconditionally, the jammed sheet is not removed and the jam is increased. The disadvantage is that it can be damaged.

Furthermore, there is a drawback in that even paper sheets on one conveyance path must be removed under the condition that none of the sensors detects banknotes.

(Means for Solving the Problems) A paper sheet conveyance device according to the present invention includes a paper sheet conveyance mechanism, a plurality of sensors that detect paper sheets on a conveyance path, and a jam sensor that indicates under which sensor a jam has occurred. a memory means for storing information; a means for determining activation or non-starting of a conveyance path by referring to the jam information stored in the memory means; and means for controlling the conveying path so as not to start if the paper sheet is not removed at the time of restart.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows a basic configuration diagram of an embodiment of a paper sheet conveying device according to the present invention. 4, a control section 2 for controlling these, and an operation section 1 for giving commands to the control section 2.

FIG. 2 shows a concrete example of the sheet conveying device according to this embodiment. The conveying mechanism 3 in FIG.
The sensor 4 is composed of an A sensor 8, a B sensor 9, and a C sensor 10.

The paper sheets are separated and fed out one by one from the feeding section 5, conveyed along the conveyance path 6 in the direction from the A sensor 8 to the C sensor 10, and stored in the storage section 7.

These operations are controlled by the control section 2.

FIG. 3 shows a schematic flow of control and operation of this embodiment.

Now, in FIG. 2, suppose that a jam occurs under the C sensor 10 on the conveyance path 6 during the conveyance operation (step 101), and the control unit 2 stops the conveyance path 6 (step 102). ), information that a jam has occurred under the C sensor is stored in the battery-backed RAM.

(Step 103).

The operator removes the jammed sheet from the conveyance path 6 and uses the operation unit 1 to instruct the conveyance path to be cleared (step 104).

When the control unit 2 is instructed by the operation unit 1 to clear the transport path,
Step 10: Read out information on the location of the sensor where the jam occurred from the battery backup RAM.
5) After the sensor check (step 106), the presence or absence of a paper sheet under the jam occurrence sensor is checked (step 107). At this time, when the conveyance path is stopped, the paper sheet that has already been fed out is stopped under the sensor. Therefore, it is not concerned whether or not a sensor other than the sensor in which the jam occurred is detecting the paper sheet.

Thereafter, if a paper sheet is detected by the sensor 10, an alarm is generated and the conveyance path is not activated, and if no paper sheet is detected, the conveyance path is activated and the conveyance path is cleared.

(Effects of the Invention) As explained above, when a jam occurs under a sensor on a conveyance path, the present invention stores the location of the jam occurrence sensor in a back-up RAM, so that the next conveyance can be carried out. When starting the conveyance path, the previous jam information is read out and compared with the status of the corresponding sensor to determine whether the conveyance path is activated or not.Therefore, for example, if a jammed paper sheet is conveyed without being removed due to an operator's error. Even if the path clearing operation is performed, paper jams will not increase, and damage to paper sheets can be prevented.Of course, these functions are effective even after the power is turned off and restarted.
