Problems solved by technology

However, in the case of using an encoder, although the amount of rotation of the motor can be accurately detected, there may be cases where the gap between the meshes of the rollers used is large, or the medium slips in the conveyance path, and it may not be possible to identify the detected object with high accuracy.

no. 1 Embodiment

[0069] (A1) Hardware composition:

[0070] figure 1 It is explanatory drawing which shows typically the hardware structure of the automatic teller machine 10 (it is also hereafter called ATM10) which is one Example of this invention. The ATM 10 is installed in, for example, a financial institution, a retail store, a public facility, etc., and automatically provides services such as cash registers provided by the financial institution or the like in accordance with user operations.

[0071] The ATM 10 has a card mechanism 22 , a passbook mechanism 24 , a statement mechanism 26 , a coin handling mechanism 28 , a banknote handling mechanism 30 , a customer operation unit 42 , a control unit 50 , and a journal printing mechanism 60 . The card mechanism 22 is a mechanism for reading information such as a user's account number from an automatic teller card inserted into a card slot. The passbook mechanism 24 is a mechanism for reading information such as a user's account number fr...

example 1

[0103] In the above embodiment, the recognition unit 302 adopts image 3 The configuration described in , is not limited to this, and various forms can be employed. Figure 9 This is an explanatory diagram for explaining the configuration of the recognition unit 302A as Modification 1. FIG. The identification part 302 has the conveyance belt 328A which conveys the banknote P, and the conveyance roller 323A, 324A which has the driving force for driving the conveyance belt 328A. The banknotes P are conveyed according to the conveyance speed of the conveyance belt 328A. In addition, the conveyance roller 323A is provided with the scale S similarly to the conveyance roller 323, and rotates according to the conveyance speed of the conveyance belt 328A. The light source 327A illuminates the conveyance roller 323A. The reflected light from the conveyance roller 323A is reflected by the mirror 326A, and is read by the image sensor 320A as scale information. Subsequent processing i...

Deformed example 2

[0107] In the above-mentioned embodiment, the conveyance roller 323 is in direct contact with the banknote P, but it is not limited to this, and the conveyance roller 323 may be a roller which receives the propulsion force of the banknote P indirectly and rotates. For example, a roller other than the conveyance roller 323 (referred to as roller 323 a ) may rotate in direct contact with the banknote P, and the conveyance roller 323 in contact with the roller 323 a may be rotated by the rotational force of the conveyance roller 323 a. In this way, the same effect as that of the above-described embodiment can also be obtained.

Abstract

This medium recognition device is for recognizing a medium being conveyed, and is equipped with: a conveyance unit that drives a certain power source in order to convey a medium; a line sensor that is provided in a line in an intersecting direction with respect to the medium conveyance direction in order to read at least a partial appearance of the medium being conveyed; a medium image acquisition unit that obtains a medium image which is an image generated on the basis of a signal obtained from the line sensor; an operating unit that operates according to the actual conveyance speed at which the medium is actually conveyed; an operation image acquisition unit that obtains an operation image which is an image generated by reading the operating unit at a predetermined interval while the medium image acquisition unit is reading the medium; a parameter acquisition unit that analyzes the operation image in order to obtain a parameter which reflects the actual conveyance speed; and a medium recognition unit that recognizes the medium image on the basis of the obtained parameter. Consequently, behavior of the medium can be highly accurately recognized.

Description

technical field [0001] The present invention relates to a technique for identifying conveyed media. Background technique [0002] The technique of recognizing conveyed media, such as a banknote processing apparatus, a printing apparatus, a ticket gate, etc., is well-known (for example, the following patent document 1). In conveying a medium, a motor is generally used as a power source, and an encoder or a resolver for detecting the conveyed amount of the medium is provided on the motor. In addition, in order to identify the medium being conveyed, a line sensor intersecting the conveying direction of the medium is provided. These devices improve the accuracy of medium identification by correcting the data of the medium acquired by the line sensor based on the conveying amount or conveying speed detected by the encoder. However, when an encoder is used, although the amount of rotation of the motor can be accurately detected, there may be cases where the gap between the meshe...
