Description
Technical field
The utility model relates to a kind of scanning means that flip opens and closes detecting function that has, and relates in particular to a kind of scanning means of detecting the flip keying by sensing ambient light.
Background technology
Scanning means such as existing photocopier, scanner, multifunctional paper feeding machine before scanning and printing, all must carry out for example fluorescent tube preheating action earlier usually, make the brightness of scanning light source tend towards stability, thereby obtain good scanning effect.
Fluorescent tube preheating action can be manually opened by the user.More humane for it, if can when the user starts flip, start fluorescent tube preheating action immediately, will advantageously save time for the user.
In order to detect the unlatching of flip, a kind of traditional practice is to use the LED sensor configuration below glass platform, by the flip that emits beam, and is received from the light signal that flip is reflected, and under normal circumstances can detect the unlatching of flip.Yet effective reconnaissance range of this arrangement for detecting is narrow, and when still being placed with file on the glass platform, whether this arrangement for detecting can't detect flip and open.Another kind of traditional practice is to utilize hall effect sensor to detect the unlatching of flip, yet this transducer need be set up electromagnetic field, therefore comparatively bothers on the implementation.
Fig. 1 shows the disclosed a kind of scanner power open-and-close device with flip control of TaiWan, China patent the 566778th communique.As shown in Figure 1, this scanner comprises body 101, flip 102 and glass platform 103.Flip 102 articulates by pivot structure 104 with body 101.The top board 105 of body 101 is offered dead zone 106.Transducer 107 is to be installed in top board 105 times and corresponding with saturating dead zone 106.Flip 102 has the member 108 of shake-up, when flip 102 covers on body 101, touches member 108 and inserts saturating dead zone 106, and touch transducer 107.Though this scanner can be detected the unlatching of flip, yet when excessive file blocks dead zone 106, will influence the insertion that touches member 108, and the situation that causes file to be pierced.In addition, the complex structure of this scanner need just can be reached desired function making particular design aspect flip and the housing two.
The utility model content
Therefore, a purpose of the present utility model provides a kind of scanning means that flip opens and closes detecting function that has, and it can not influence under the situation about covering, and utilizes ambient light to detect the keying state of flip, carries out preheating or other action.
For achieving the above object, the utility model provides a kind of scanning means that flip opens and closes detecting function that has, and it comprises body, is arranged on the scan module in the body, the flip that is pivotally attached to body, optical sensor and power-supply controller.Body has scanning platform, be used for for file be placed on it above.Optical sensor is arranged on flip or the body, is used for receiving when flip is raised the light signal of ambient light.Power-supply controller is electrically connected to optical sensor, is used for power supply supply according to light signal gated sweep module.
Detect the keying of flip by the mode of sensing ambient light, can reach reliable detecting effect.And, see through the keying detecting of flip, can control the carrying out of fluorescent tube preheating action, print unit preheating action and paper size detecting action, be used for saving user's valuable time.
Description of drawings
Fig. 1 shows a kind of scanner power open-and-close device with flip control that TaiWan, China patent the 566778th communique is disclosed;
Fig. 2 shows the scanning means that flip opens and closes detecting function that has according to the utility model first embodiment;
Fig. 3 shows the scanning means that flip opens and closes detecting function that has according to the utility model second embodiment;
Fig. 4 shows the scanning means that flip opens and closes detecting function that has according to the utility model the 3rd embodiment.
Embodiment
Fig. 2 shows the scanning means that flip opens and closes detecting function that has according to the utility model first embodiment.As shown in Figure 2, the scanning means 10 with flip keying detecting function of present embodiment comprises body 20, scan module 30, flip 40, optical sensor 50 and power-supply controller 60.
Power-supply controller 60 is to be electrically connected to optical sensor 50, is used for power supply supply according to light signal gated sweep module 30.For example, power-supply controller 60 carries out preheating according to light signal control fluorescent tube 32.This preheating action can be carried out after scanning means enters park mode usually.
Therefore, when flip 40 was started, optical sensor 50 can sense ambient light, and fashionable when flip 40 tegmentums, optical sensor 50 can't sense ambient light.Perhaps, when the brightness of the ambient light of 50 sensings of optical sensor when secretly brightening, expression flip 40 is started, when the brightness of the ambient light of 50 sensings of optical sensor during from bright deepening, expression flip 40 is covered.
Fig. 3 shows the scanning means that flip opens and closes detecting function that has according to the utility model second embodiment.As shown in Figure 3, present embodiment is similar to first embodiment, difference be optical sensor 50 be device on body 20, all the other similar parts no longer are described in detail.
Fig. 4 shows the scanning means that flip opens and closes detecting function that has according to the utility model the 3rd embodiment.As shown in Figure 4, the scanning means of present embodiment further comprises print unit 70 except all members that comprise first embodiment, and power-supply controller 60 carries out preheating according to light signal control print unit 70.In addition, scanning means 10 also comprises automatic paper conveying apparatus 80, and power-supply controller 60 is the paper feed function forbidden energy that make automatic paper conveying apparatus 80 according to light signal.Can prevent so whether the hinge that detects automatic paper conveying apparatus is positioned at the normal position, can prevent automatic paper conveying apparatus paper feed under improper situation.Scanning means 10 also comprises paper size detector 90, and power-supply controller 60 makes 90 activations of paper size detector detect paper size according to light signal.Owing to utilize flip to have quite good and reliable effect from being opened to the paper size of detecting during this period of time that covers, so the utility model can integrate into this function, and excellent sheet size detecting effect is provided.
By scanning means of the present utility model, the user has forgotten file to be taken out and file still is placed on the glass platform in real time, still can detect the unlatching of flip.And scanning means of the present utility model only need be set up an optical sensor, just can reach the keying effect of detecting flip, and does not need to utilize as known technology complexity and expensive electromagnetic field or transceiver configuration to carry out the detecting that flip opens and closes.Moreover the set-up mode of optical sensor can make it flush contact-making surface at flip or body, and can not hurt mass file or influence covering of flip as above-mentioned patent the 566778th communique.
The specific embodiment that is proposed in the detailed description of preferred embodiment just is used for making things convenient for explanation technology contents of the present utility model, rather than with the utility model narrow sense be limited in the foregoing description, under the situation of the spirit and scope that do not exceed the utility model claim, the many variations of being done is implemented, and all belongs to scope of the present utility model.
