Abstract
The utility model relates to a method to eject out or close a CD-ROM drive tray stand by touch control and CD control, which mainly comprises a small conductive door arranged on the surface of the panel of the CD-ROM drive, an infrared CD detecting device arranged on the tray stand and relative added circuits. When the small door on the panel of the CD-ROM drive is touched by hand, the tray stand is ejected out or closed. When no CD is on the tray stand ejected out, a CD is put on and the tray stand will be automatically closed after two seconds. When a CD is on the tray stand ejected out, the CD is taken away and the tray stand will be automatically closed.
Description
The utility model belongs to the improvement to computer CD ROM tray rack control method, is specifically related to a kind of method of ejection of computer CD ROM tray rack or closing control.
Traditional CD ROM support tray frame ejects or closes all to have and is to realize with the ejection close key in the control CD-ROM drive panel lower right corner, and button is less, when CD-ROM drive is lower than operator's head, under the situation that tray rack ejects, go operation to eject close key, the tray rack that is ejected blocks, and it is very inconvenient to operate.
The utility model provides a kind of CD ROM support tray frame to eject shutoff control unit automatically at the problems referred to above, makes the operation CD-ROM drive very convenient.
To achieve these goals, as shown in Figure 1 it mainly by:
1 conduction CD-ROM drive wicket, touch signal amplifying circuit and signaling conversion circuit etc. are formed tangible control tray rack and are ejected stopping device.
2 are positioned at CD pick-up unit, signal processing circuit and the chronotron on the tray rack etc. forms and detects CD action control tray rack A.C.D..Connect the CD-ROM drive power supply, when touching CD-ROM drive panel wicket with hand, touch signal is exaggerated conversion after differentiator, forward output, adaptation are handled the back and ejected signal of close key for the CD ROM support tray frame, and tray rack ejects or closes.
After tray rack ejects, on the tray rack during no CD, it is shown in Figure 3 to tray rack precalculated position such as Fig. 5 to put into CD, operating characteristic gained according to rejection gate, do not detect by the infrared ray of CD reflection as infrared receiver tube wherein, rejection gate output is failure to actuate, represent that then CD is not put into the position, tray rack is failure to actuate, all detect by the infrared ray of CD reflection as three infrared receiver tubes, it is high level that rejection gate is jumped by low level, represent that then CD is to be put into the position, signal is exported a positive pulse behind the differentiator differential, amplify through amplifier again, pulse-separating circuit is separated back trigger delayer time-delay, delay time and export a positive voltage after 2 seconds, chronotron automatically resets in output one positive voltage, form a positive pulse, pulse is handled through differentiator, forward output, adaptation is handled the back and is ejected signal of close key for the CD ROM support tray frame, and tray rack is closed.
After tray rack ejects, when on the tray rack CD being arranged, remove CD, wherein infrared receiver tube loses infrared ray, then rejection gate is a low level by the high level jumping, then represent to remove CD, signal is exported a negative pulse behind the differentiator differential, amplify through amplifier again, pulse-separating circuit is separated, the trigger delayer time-delay of the anti-phase back of phase inverter, delay time and export a positive voltage after 2 seconds, chronotron automatically resets in output one positive voltage, form a positive pulse, pulse is handled through differentiator, forward output, adaptation is handled the back and is ejected signal of close key for the CD ROM support tray frame, and tray rack is closed.
Advantage of the present utility model and good effect are:
1 CD-ROM drive wicket such as Fig. 3, tray rack top (not illustrating among the figure) or 2,3 replaced the less button in the CD-ROM drive panel lower right corner, make the operation tray rack flick close more convenient.
2 put or remove on the tray rack optical disc tray frame can close automatically.
3 can reduce or save panel button intuitively, make panel more simple and direct attractive in appearance.
Below be that each accompanying drawing of the utility model is made brief description:
Fig. 1 is a circuit block diagram of the present utility model
Fig. 2 is the voltage oscillogram of Fig. 1 circuit block diagram each point
Fig. 3 is the front view that the position, touch point can be set
Fig. 4 is that infrared emission tube and infrared receiver tube device are installed in the vertical view that drawn game portion in position amplifies on the tray rack
Fig. 5 is that infrared emission tube and infrared receiver tube are installed in the left view on the tray rack.
Describe preferred embodiment of the present utility model in detail below with reference to each accompanying drawing:
The utility model CD-ROM drive panel (1) is a plastic front board as shown in Figure 3, ejecting close key replaces by being installed in the panel wicket (2) or (3) that have electric conductivity on the tray rack, (2) or (3) be connected in touch amplifying circuit in the machine with lead, pick up the induced signal of human body touch.
Three pairs of infrared ray launches and receives pipes (2) (3) (4) are installed in the position on the tray rack (1) as shown in Figure 4, (5) (6) are the transmit-receive tube after amplifying, three infrared emission tubes are by CD driver+5V power supply step-down power supply, three infrared receiving tubes are connected in the OR-NOT circuit input end with thin flat cable respectively, and three groups of its effects of infrared ray launches and receives pipe are to detect whether CD is put into the precalculated position and to removing the detection of CD.
Infrared ray launches and receives pipe (5) (6) is installed in the left view on the pallet (1) as shown in Figure 5, (5) (6) setting angle and position depend on CD be put into tray rack precalculated position minimum point (3) and CD under outstanding commentaries on classics the at a high speed (2) three infrared receiver tubes can stable detection to infrared ray and can.
Touching circuit as shown in Figure 1 conducts electricity wicket, touch signal amplifier, signaling conversion circuit and a back level control signal output circuit by panel and constitutes.The CD testing circuit is made of infrared ray disc detector, signal processing circuit, chronotron and the back level control signal output circuit etc. that are positioned on the tray rack.The chronotron control amplifier start in 2 seconds of starting shooting could be amplified output prime signal in 2 seconds afterwards, and its effect is to prevent that CD driver from having CD start output one pulse to flick tray rack.The each point oscillogram is seen Fig. 2.
Safety in order to ensure CD-ROM drive; can add a pallet protective device, when tray rack ejects, eject detector switch and give signal of chronotron as Fig. 1; the chronotron trigger; as delayed time 10 seconds, chronotron will be exported a positive voltage, and chronotron automatically resets in output one positive voltage; form a positive pulse; pulse ejects signal of close key for the CD ROM support tray frame after differentiator processing, forward output, adaptation are handled, and tray rack is closed, and effectively protects tray rack not fractureed.Close pallet as chronotron other situation of delaying time in 1 to 9 second, chronotron will automatically reset.
Claims (1)
- A kind of CD ROM support tray frame that touches control and CD control flicks stopping device, it is characterized in that: first device comprises that the tangible control tray rack that panel conduction wicket and touch signal amplifying circuit, signaling conversion circuit etc. are formed ejects stopping device; Second device comprises the detection CD action control tray rack A.C.D. of the compositions such as infrared ray disc detector, signal processing circuit and chronotron that are installed on the tray rack.
