Abstract

The utility model relates to a method of ejecting or closing an intellectual laser disc player tray frame controlled by touching and a disk, which is mainly composed of a conductive wicket of a laser disc player panel, an infrared optical disc tester arranged on the tray frame and associated circuits. When the conductive wicket of the laser disc player panel is touched by hand, the tray frame is ejected or closed. When the ejected tray frame has no optical discs, an optical disc is positioned on the tray frame, and the tray frame can be closed automatically after two seconds. When the ejected tray frame has an optical disc, the optical disc on the tray frame is removed, and the tray frame can be closed automatically after two seconds. When the tray frame is ejected for ten seconds without an action, the tray frame can be closed automatically. The tray frame of the utility model has the advantage of humanization so as to increase the science content of the product.

Description

A kind of Intelligent Laser video disc player tray rack

The utility model belongs to the improvement to Laser disc machine tray rack control mode, is specifically related to a kind of mode of ejection of Laser disc machine tray rack or closing control.

Traditional Laser disc machine tray rack ejects or closes all and realizes with control Laser disc machine panel ejection close key, and button is less, put at every turn or take out CD and all get repetitive operation ejection close key, it is very inconvenient to bring for the operation tray rack, very easily damages through long-term pressing keys.

The utility model provides a kind of Intelligent Laser video disc player tray rack and interlock circuit at the problems referred to above, and changes button and be controlled to be and touch control and CD is controlled.

To achieve these goals, as Fig. 1 shown in Figure 2 it mainly by: be installed on last three groups of infrared detection optical disc apparatus of Laser disc machine tray rack (1) (3) (4) (5) and surface conduction panel wicket (2) and form as the interlock circuit of Fig. 2.

As Fig. 2, shown in Figure 5ly enter when waiing upon the machine duty when Laser disc machine, with hand touch panel conduction wicket, touch signal is exaggerated conversion and gives signal of Laser disc machine tray rack control circuit after differentiator, forward output circuit, adaptation are handled the back, and tray rack ejects or closes.

After tray rack ejects, on the tray rack during no CD, put CD to the tray rack precalculated position shown in Fig. 3 (4) (5), operating characteristic gained according to rejection gate, do not detect by the infrared ray of CD reflection as infrared receiver wherein, the rejection gate no-output, 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 receivers, it is high level that rejection gate is jumped by low level, determine CD 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, output one positive voltage after 2 seconds of delaying time, chronotron automatically resets in output one positive voltage, form a positive pulse, pulse is handled through the differentiator differential, forward is exported a signal, triggers the Laser disc machine tray rack and closes; When on the tray rack that ejects CD being arranged, remove CD, infrared receiver does not detect by the infrared ray of CD reflection, it is low level that Sheffer stroke gate is jumped by high level, differentiator export a negative pulse, again through amplifier amplify, pulse-separating circuit is separated, phase inverter is anti-phase, chronotron time-delay output one positive voltage after 2 seconds, chronotron automatically resets in output one positive voltage, form a positive pulse, pulse output one signal triggering Laser disc machine tray rack after differentiator processing, forward output, adaptation are handled is closed.

Advantage of the present utility model and good effect are:

1 as shown in Figure 4 Laser disc machine wicket (2), tray rack top (not illustrating among the figure) replaced the less button of Laser disc machine panel, the operation tray rack is ejected close more convenient.

The 2 optical disc tray framves of putting or removing on the tray rack can be closed automatically, save the trouble of operation push-button and the safety of effective protection tray rack.

3 tray racks have the hommization function.

Below be that each accompanying drawing of the utility model is made brief description:

Fig. 1 is that infrared ray receives transmitter position view on tray rack

Fig. 2 is a circuit block diagram of the present utility model

Fig. 3 is that infrared ray receives transmitter duty partial left side view

Fig. 4 is a Laser disc machine panel conduction wicket view

Fig. 5 is the utility model workflow diagram

Describe preferred embodiment of the present utility model in detail below with reference to each accompanying drawing:

The utility model Laser disc machine panel (1) is a plastic front board as shown in Figure 4, ejecting close key replaces by being installed in the panel wicket (2) that has electric conductivity on the tray rack, (2) be connected in touch amplifying circuit in the machine with lead, pick up the induced signal of human body touch.

Three pairs of infrared transmitting receivers (3) (4) (5) are installed in the position on the tray rack (1) as shown in Figure 1, three infrared transmitter are by direct current+5V step-down power supply, three infrared receivers are connected in the input end of Sheffer stroke gate respectively with thin flat cable, three groups of its effects of infrared transmitting receiver are to detect whether CD is put into the position and to removing the detection of CD.

Infrared transmitting receiver (2) (3) is installed in the left view on the tray rack (1) as shown in Figure 3, (2) (3) setting angle and position depend on that CD is put into tray rack precalculated position minimum point (4) and the CD peak of (5) under high speed rotating, three infrared receiver tubes can stable detection to infrared ray and can.

Touching circuit as shown in Figure 2 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 2 seconds chronotrons of starting shooting, control amplifier start could amplify output prime signal after 2 seconds, its effect is to prevent from that Laser disc machine inside from having CD to start shooting to export a pulse to flick tray rack.

Safety in order to ensure the Laser disc machine tray rack; working as tray rack as Fig. 2 ejects; eject detector switch and give signal of chronotron; the chronotron trigger, the 10 seconds chronotrons of delaying time will be exported a positive voltage, and chronotron automatically resets in output one positive voltage; form a positive pulse; pulse is given signal of Laser disc machine tray rack control circuit through differentiator processing, forward output, adaptation after handling, 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.
