2. Description of the Related Art When detecting a superposed medium, how to surely detect the superposed medium without being affected by the paper quality, paper thickness and shape of the superposed medium, and how to simplify the detection mechanism and reduce the cost. It will be important to realize in. In the prior art, as disclosed in Japanese Patent Application Laid-Open No. 6-263288, a photoelectric tube type two-sheet detector and an ultrasonic type two-sheet detector are combined as a stack medium detecting means, and any two sheet detectors are provided. When the overlap of the media is detected, a two-sheet detection signal is transmitted. This is because each of the two-sheet detectors is a medium quality paper,
This is because the detection sensitivity varies depending on the paper thickness, the paper color, etc., and when each of the two-sheet detectors is used independently, one medium may be erroneously detected as two sheets of medium or vice versa. . Further, as seen in JP-A-5-139572, a detection roller that is displaced according to the thickness of a medium, an output unit that obtains an output voltage proportional to the displacement amount of the detection roller, and an output waveform of the output unit An arithmetic means for sampling and averaging peak values is provided, and the averaged data is compared with the slice level corresponding to the continuous amount of medium to determine the overlap of the medium.

[0003]

In the method of detecting the overlap of the media, which has the above-mentioned phototube type two-sheet detector and ultrasonic type two-sheet detector together, it is necessary to provide a plurality of different types of detectors and control units. It is not cheap because it exists. Further, the method using the medium thickness detection roller is not cheap at all as in the known example described above, and the detection roller which is displaced according to the thickness of the medium is good even for a very thin medium. In order to obtain a high output, precision is required for the mounting adjustment of the roller and the dimensions of the parts. Further, in common with the above two methods, the customer or the operator is unaware of the fact that the mediums are overlapped until the mediums are detected in the apparatus and returned. INDUSTRIAL APPLICABILITY The present invention is not affected by the paper quality, paper thickness, paper color, etc. of the medium, does not use an expensive two-sheet detector, does not require attachment adjustment of components or dimensional accuracy of components, and can process even a little. It is an object of the present invention to provide an inexpensive overlapping medium detection mechanism in which the customer or the operator can easily notice the overlapping of the medium at the initial stage of 1.

Next, the operation of the overlapping medium detecting mechanism of the present description will be described with reference to the flow chart shown in FIG. The customer selects a transaction (41) for a passbook transaction or a transfer process. At this time,
On the device side, condition A or condition B shown in FIG. 11 is set. The selected medium is then inserted and inhaled (42). At this time, the insertion port roller 3 of FIG. 4 is driven and the overlap detection roller 31 of the present invention is opened. Next, the passbook or the transfer sheet conveyed by a certain amount by the insertion port roller 3 is stopped (43), and the medium presence / absence detection sensors 32, 33, 34, 37 in FIG. 4 and the customer transaction selection (41) are selected. Match the set conditions A and B. For example, when the passbook is selected in the transaction (41), the condition A is set, and when the medium is stopped (43) and the detection result of the medium presence / absence detection sensor matches the condition A of FIG. Proceed to (45), but if the detection result does not match condition A or condition G, there is an abnormality such as a medium different from the main transaction or deformation of the medium, or it is a customer insertion error, and the medium is returned ( 44). Next, the overlap detection process (45) of the present invention is performed by the overlap detection roller 31 shown in FIG. At this time, the insertion port roller 3 is open. At this time, for example, as shown in FIG.
When the passbook 11 is overlaid and inserted on the back side of the transfer paper 21 inserted as the condition B set in the transaction selection (41) in FIG.
The passbook 11 is moved in three directions and is pressed against the conveyance reference surface 51. The transfer paper 21 is detected as having a medium by the overlap detection 2 sensor 37, and it is determined that there is an overlap, which is the condition D in FIG. If there is overlap, the medium is returned (44).
Go to. Even if the detection condition of the sensor does not change from the set condition at the time of the transaction selection (41) by the overlap detection process (45), that is, the condition A becomes the condition E in FIG. 11, the condition B becomes the condition F. If it becomes, it is determined that the process is normal and the process proceeds to the next process (46), for example, the optical reading process. Further, in FIG. 6, the passbook 11 and the transfer paper 21 are exposed to the outside from the device insertion opening from the Z-Z side with respect to the transport direction 52, and the separation of the stack medium by the stack detection roller 31 is visible to the customer. Therefore, it is possible to prompt the customer to make a decision to suspend the transaction processing.

FIG. 7 shows the separation process of the overlapped media by the overlap detection roller 31. Passbook 11 and transfer paper 21
When the sheets are overlapped with each other and inserted into the overlap detecting roller portion 31, the upper side overlap detecting roller 31 rotates in the direction of arrow 63 so as to move the transfer paper 21 in the direction of arrow 61. At this time, the lower overlap detection roller 31 'rotates in the direction of arrow 64 to move the passbook 11 in the direction of arrow 62.

FIG. 8 and Equations 1 and 2 shown below show the relationship between the wear coefficient of the overlap detection roller 31 and the medium. μ1> μ2 ... (Equation 1) μ3> μ2 ...
Assuming that the friction coefficient between the passbook 11 and the lower overlap detection roller 31 ′ is μ3, the upper overlap detection roller 31 described above transfers the transfer paper 21, and the lower overlap detection roller 31 ′ uses the passbook 1
1 is moved in the opposite direction.
The materials of the rollers 31 and 31 ′ satisfying μ1> μ2 shown in (1) and μ3> μ2 shown in Formula 2 are selected. When a card inserted by mistake is assumed as one of the overlapping media, the material of the roller may be selected in consideration of the coefficient of friction between the roller and the card.

Further, as shown in FIG. 9, when the media are normal passbooks 11 or transfer papers 21 with no overlap, the following expression 3 is the coefficient of friction for preventing the media from separating from the conveyance reference surface 51. Shows the relationship.

Μ3 ≧ μ1> μ2 (Equation 3) The roller 31 satisfying μ3 ≧ μ1> μ2 as shown in Equation 3;
The material of 31 'is selected. At this time, the pressing force N of the upper and lower overlap detection rollers 31 and 31 'is made small, and the sandwiching force between the upper and lower rollers and the medium is suppressed to a necessary minimum to induce slip, and the upper and lower overlap detection rollers 31 and 31'. ´
The contradiction of the medium conveyance direction of is solved. In the above case, both the detection rollers 31 and 31 'are rotated, but either one may be rotated and the other may be fixed.

FIG. 10 shows the operation in FIG.
Shows an auxiliary operation in the case where the sheet is separated from the conveyance reference surface 51, in which the upper side overlap detection roller is in the direction of arrow 91 and the lower side overlap detection roller is in order to align the medium with the conveyance reference surface after the overlap detection. Similarly to the above, the medium 11 is rotated in the direction of the arrow 64 to move the medium 11 in the direction of the transport reference surface 51.

Up to this point, the stack detection roller 31 of the stack medium detection mechanism of the present invention operates using a rotation drive system (not shown). For example, in FIG. 10, the lower stack detection roller 31 'is in the direction of arrow 64. The drive means can be omitted by using a bearing with a one-way clutch that is rotatable only. In this case, the upper overlap detection roller 31 is indicated by the arrow 91.
The medium 11 is rotated in the direction to move the medium 11 to the reference surface side. By this movement, the lower overlap detection roller 31 'having a bearing with a one-way clutch rotates in the direction of arrow 64. Further, when the lower side overlap detection roller 31 ′ has a bearing with a one-way clutch, as shown in FIGS. 8 and 9, the lower side overlap detection roller 31 ′ does not rotate, and the medium 1
Prevents 1 from moving.

As described above, according to the present invention, it is not affected by the paper quality, paper thickness, paper color, etc. of the medium, and the expensive two-sheet detector is not used, and the mounting adjustment of the parts and the parts It does not require dimensional accuracy, and the customer or operator can notice the overlapping of media at the initial stage of processing.
It is possible to provide an inexpensive stacking medium detection mechanism.
