Description
Technical field
The present invention relates to a kind of medium testing agency for flaky medium and use the media processing apparatus of this mechanism.
Background technology
Flaky medium (for convenience of description, hereinafter referred to as medium) treating apparatus, as printer, scanner, card reader, coin identifier etc., usually medium testing agency is set in media transport path, medium whether is had to be positioned at testing agency position for detecting, when there being medium to be positioned at testing agency position, medium testing agency exports corresponding detection signal, and media processing apparatus starts the media processes operations such as printing, scanning in good time according to this signal.Medium testing agency uses photoelectric sensor usually, and photoelectric sensor comprises optical transmitting set and optical receiver, and wherein, optical transmitting set is used for emission of light, the light that optical receiver is launched for receiving optical transmitting set, and exports corresponding detection signal.
If when not having on the light transmition path of medium between optical transmitting set and optical receiver, optical receiver can receive most of light that optical transmitting set is launched, namely the light intensity that receives of optical receiver is large, therefore, optical receiver exports the first detection signal, if when having on the light transmition path of medium between optical transmitting set and optical receiver, the propagation of light due to dielectric impedance, optical receiver does not receive or only receives the some light transmitted through medium, namely the light intensity that receives of optical receiver is little, therefore, optical receiver exports the second detection signal, so, the signal exported according to the optical receiver of photoelectric sensor can judge the presence or absence of medium.
Fig. 1 a is the structural representation of a kind of medium testing agency of the prior art, as shown in Figure 1a, the optical transmitting set 31 ' of medium testing agency and optical receiver 32 ' are oppositely arranged, lay respectively at the both sides of media transport path 1 ', when position place of medium testing agency does not have medium, the light that optical transmitting set 31 ' is launched passes to optical receiver 32 ' by the opening 2 ' on media transport path 1 ', can be received by optical receiver 32 '.The shortcoming of this medium testing agency is, in Long-Time Service process, dust is stacked into the surface of optical transmitting set 31 ' or optical receiver 32 ' by opening 2 ', hinder optical transmitting set 31 ' emission of light and optical receiver 32 ' reception light, thus reducing the sensitivity of optical receiver induction light line strength, the detection signal that optical receiver is exported is unreliable.Meanwhile, if water, wet goods material cover optical transmitting set and/or optical receiver surface, the detection signal that also optical receiver can be caused to export is unreliable.
In order to solve the problem, occur again another medium testing agency in prior art, as shown in Figure 1 b, at opening 2 ', place arranges transparent sealed cover 4 ', to stop dust, water, wet goods material buildup to the surface of optical transmitting set 31 ' and optical receiver 32 '.This medium testing agency makes photoelectric sensor and media transport path isolate by arranging seal closure, solve because of dust, water, wet goods Substances Pollution photoelectric sensor and affect the problem of testing result, but the light that optical transmitting set 31 ' is launched is after air scattering to transparent sealed cover 4 ', only have a very little part can be received by optical receiver 32 ' through seal closure 4 ', greatly reduce light intensity, the change in detection signal that optical receiver is exported is not obvious, controller is caused not easily to judge whether there is medium in media transport path, therefore the testing result of this medium testing agency is unreliable.
Therefore, medium testing agency of the prior art cannot meet good airproof performance, the reliable demand of testing result simultaneously.
