Description

M267771, Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is about a scanning device with a flap opening / closing detection function = it relates to a method for detecting the opening and closing of a flap by sensing ambient light Scanning and inserting [Previous technology] Existing photocopiers, scanners, multi-function printers, etc. Scanning and printing are usually performed before #scanning, such as lamp pre-clamping, to stabilize the brightness of the scanning light source. And get a good scanning effect: the lamp, preheating action, can be turned on manually by the user. In order to: 化 化 2: If the user can immediately start the lamp pre-cranking action when the user lifts the cover, it will benefit the soil and save time for the user. …, 骞 δ. ί η: Opening of the lift 一种 A traditional method is to use the ud sensor under the stage, by emitting light to the lift cover, and receiving self-starting. What's more, under the normal circumstances, the Kaiping of the flip cover can be detected under normal circumstances. Second: Still Jin: The effective detection range of the detection device is narrow, and when the glass door:-胄 file, this detection The device cannot detect whether the cover is lifted. The traditional method is to use a Hall-effect sensor (Hal 1 to establish electromagnetic cutting, so it is more troublesome to implement. Cover and the Republic of China Patent No. 566 778 Gazette discloses- This kind of device is a lifting and opening device. As shown in FIG. 1, the scanner includes 101 # 蕤 rou / cover 102 and a glass platform 103. The cover 102 and the body are pivotally connected by a shaft structure 104 in error. Opening of the top plate ι〇5 of the airframe

Page 6 M267771 IV. Creative Instructions (2) There is an open area 106. The sensor 107 is installed under the top plate 105 and corresponds to the through-hole 106. The flip cover 102 has a trigger member 108, and when the flip cover 102 is covered on the body 1 (H, the 'touch member 108 is inserted into the through-hole area 10; and a 5 mm scanner can be detected. The opening of the flip cover, however, when the document that has been blocked by the transparent area 106, it will affect the insertion of the trigger member 108, and cause the document to be pierced. In addition, the structure of this scanner is complicated. ^ Special design in two aspects of the flip cover and the casing can achieve the desired [scanning capacity of the new type so the function sweeps the light to the debt.] 'A tracing device of this creation measures the above purpose of the flip cover.' The opening and closing shape of the original set, the frame has a cover set to one of the body, including a flip cover, and the purpose of sweeping is to provide a state that does not affect the cover. In the case of preheating or one of the opening and closing of the cover with a flip cover, the light signal is controlled by a pre-processed tube, which can be made into a drawing platform cover or a serial number. Scanning detection week to detect heat action, so as to 'use on the donor, The electricity of the electric controller module is affected by light. In addition, the province of printing uses a document to supply power to the electrical system, through the preheater's precious device and a cover placed on the cover. The light power supply controls it. The sensor is received when the light is on, which detects the opening and closing of the flip cover and the opening and closing detection action of the flip cover and the time of the paper. Group, device. The body sensor is based on the surrounding light, which can reach 'can control small detection movement

Page 7 M267771 Creation Instructions (3) [Embodiment] > Μ shows a cover opening and closing detection function according to the first embodiment of this creation ^ ". As shown in FIG. 2, the embodiment has a cover opening and closing detection function, and the scanning device 10 includes a main body 20, a scanning module 30, a cover 40, a light sensor 50, and a Power supply controller 6 〇. The body 20 has a scanning platform 22 for placing a document ρ thereon. The tracing module 30 includes a light tube 32 and is disposed in the body 20. The flip cover 40 series light sensor 50 is disposed on the flip cover 40 and is used for receiving the light signal of the surrounding light in the flip cover. For example, the light sensor ::: contains a photoresistor. The voltage-dividing circuit can be used to know the light ^ and f resistance value change 'to determine the opening and closing state of the cover. It is worth noting that, the light sensor 50 placed on the flip cover 40 can be straight. Platform = facing, and the body 2 around the platform 22 can be traced. = To "', the control state 60 is electrically connected to the light sensor 50 and is used for the power supply of the &#% ^ scan module 3. For example, the control: the lamp 32 is preheated. This Preheating action%: performed after the tracing device enters the sleep mode. ㈢ When exposed to light: at this time, the light sensor 50 can sense ambient light. Or i :: two t 'Γ sensor 50 cannot When the surrounding area becomes bright, it means that the cover 4 is lifted. When the light senses the brightness from dark light to change from bright to dark, it means that the cover 4 is covered. The surrounding area is shown in Figure 3. The second embodiment has a lid opening and closing function

M267771 Fourth, creation instructions (4)

Scanning device. As shown in FIG. 3, this embodiment is similar to the first embodiment, except that the light sensor 50 is installed on the main body 20, and the remaining similar points are not described again. * FIG. 4 shows the detection function of the opening and closing of the cover according to the third embodiment of the present invention = scanning device. As shown in FIG. 4, the scanning device of this embodiment includes a printing unit 70 in addition to all the components of the first embodiment, and the power supply controller 60 controls the printing unit 70 to perform preheating according to the optical signal. In addition, the scanning device 10 further includes an automatic paper feeder 80, and the power supply controller 600 disables the paper feeding function of the automatic paper feeder 80 according to the optical signal. This can prevent detection of whether the hinge of the automatic document feeder is in the normal position, and can prevent the automatic document feeder from feeding under improper conditions. Furthermore, the scanning device 10 includes a "paper size detector 90, and the power supply controller 60 enables the paper size detector 90 to detect the paper size based on the light signal. The detection of paper size from f to closing has a very good and reliable effect, so this creation can also integrate this function with a good paper size detection effect. I By using the scanning device of this creation, the user is real-time Forgot to take out the document and leave the document on the glass platform, you can still detect the opening of the flip cover. And 'The scanning device of this creation only needs to add a light sensor to detect the flip cover. The opening and closing effect, without the need to use complex and rugged electromagnetic fields or transceiver configuration to perform the debt opening and closing of the lid. Moreover, the light sensor can be set in a way that is flush with The contact surface of the flip cover or the main body does not damage the treasure or shadow as described in the above-mentioned Patent No. 56 677 8.
