Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] figure 1 It is a schematic diagram of the composition of the media processing device according to the first embodiment of the present invention. As shown in the figure, the media processing device 100 includes a control unit 11, a communication unit 12, a RAM memory 13, a FLASH memory 14, a media processing unit 15, and a delivery unit 16 And a medium overlapping detection unit 17 . in,

[0035] The control unit 11 is used to control each module to perform work. For example, the control unit 11 controls the communication unit 12 to perform data transmission between the media processing device 100 and a host (such as a personal computer connected to the media processing device); the con...

Abstract

The invention discloses a medium overlapping detection method and a medium treatment device. The medium overlapping detection method includes acquiring first detection values; acquiring section detection values; judging whether absolute values of difference values of the first detection values and the second detection values are larger than or equal to first preset threshold values; determining that media in media delivery channels are overlapping media if the absolute values of the difference values of the first detection values and the second detection values are larger than or equal to the first preset threshold values. The first detection values are reference detection values. The second detection values are acquired by means of detecting output of ultrasonic sensors when the media cover the ultrasonic sensors in medium delivery procedures. The medium overlapping detection method and the medium treatment device have the advantages that an effect of detecting overlapping of the various media with different thicknesses without frequently changing the judgment threshold values can be realized by the aid of the medium overlapping detection method and the medium treatment device, and accordingly operation can be simplified for users.

Description

technical field [0001] The invention relates to the detection field, in particular to a medium overlap detection method and a medium processing device. Background technique [0002] Existing media processing devices, such as printers, scanners, copiers, and other media processing devices, when the conveying mechanism of the media processing device conveys the media from a stack of media to the media processing device one by one, sometimes due to static electricity or moisture, etc. As a result, multiple sheets of media are overlapped and fed, which not only easily causes media handling errors, but also easily causes media jams to interrupt the operation of the device. Therefore, the media processing device usually has a function of media overlapping detection to avoid problems caused by overlapping media being transported into the media processing device. [0003] Japanese Patent Publication No. JP2000025987 discloses a medium overlap detection method: an ultrasonic sensor ...
