16、Mechanism Operation Description 3.1. General Feature This is a five disc changer mechanism for CD/DVD. The outline figure is shown below. The mechanism has CHANGE WHILE PLAY function. It open other trays for disc exchanging while one tray is at PLAY position performing recording or reproducing. The

17、mechanism can quickly change all trays with CHANGE ALL function. All trays can be move to OPEN position with one operation. There is no sensor to indicate presence of disc on any tray. 3.2. Hardware composition Below is the hardware components of the mechanism NameFunction Open Switch (OPEN-SW)The s

18、witch is used to detect normal tray opening The switch is used for detect tray being manually push/trigger when full open Home Switch (HOME-SW)Is used to detect cam gear home position Close Sensor (CLOSE-SENSOR)Used for normal single tray closing Used to detect cam gear rotate to Play Driving positi

19、on Play Switch (PLAY-SW)Detect TRV clamping complete position Stocking Switch (STOCK-SW)Detect tray completely transfer for play position to stocking positi UD Sensor (UD-SENSOR)Detect TRV vertical movement position Top Switch (TOP-SW)Detect a default position of TRV vertical movement position Drive

20、r ICTo drive Motor MotorMain driving source for changer PlungerSwitching the driving source from motor to: 1. Tray open/close 2. Drive tray to play/stock position and TRV vertical movemen 3.3. Mechanism Operation This mechanism has the following state: 1. Driving of a tray to open/close 2. Up/down o

21、peration of a traverse performs a state changes of tray. By using the plunger to lift/release of a switching gear, and the cam gear to lift/release the function gear the motor can be link to several gear trains to perform various operations. The functions that can be perform in this mechanism are de

22、scribed as below: ConditionExplanation Open current playing trayThe state to change current playing disc. All tray will be open at once and current tray at PLAY position will be expose. Open AllThe state where all trays being driven to OPEN position. The disc can be taken in or out from tray to tray

23、 by close tray one by one from top to bottom. StockThe state where the trays are stored in STOCK position PlayThe state where one of the tray 5 trays is being driven to PLAY position and clamped by traverse unit 9 CRS1 ConditionExplanation Play a TOP-SW is use in this purpose. Below is the flow char

24、t for UD selection processing. 27 CRS1 For tray 1 selection, flow chart below will be used. 28 CRS1 3.13. Fail Safe Fail safe function is for purpose of recovery of tray movement if the mechanism is not able to carry out tray open or close within a specified time. Fail safe 1: Tray can not open: Fai

25、l safe - move all trays to home position Fail safe 2: Tray can not close: Fail safe - move to next close sensor transition position Note : For Fail safe 2 : 1. If done on tray 1 - will fully go to Open position because OC gears are fully engaged 2. If done on either one of the remaining trays (2, 3,

26、 4 Farads. Resistance values are in ohms, unless specified otherwise, 1K=1,000(ohms). The marking (RTL) indicates that the Retention Time is limited for this item. After the discontinuation of this assembly in production, the item will continue to be available for a specific period of time. The rete

27、ntion period of availability is dependant on the type of assembly, and in accordance with the laws governing part and product retention. After the end of this period, the assembly will no longer be available. M Indicates in the Remarks columns indicates parts that are supplied by PAVCSG. 100 CRS1 Re
