4.2.3 Cassette housing operation outline (1) Inserted cassette type detection In its initial state, the reel disk is in the standard position, and only when a mini cassette is inserted it changes to the mini cassette position. As explained in Section 2, it is the reel change plate (Fig. 4.2.5) that changes the position of the reel disk. As previously compared in 4.2.1, the thickness of standard and mini cassettes differ. Standard cassette thickness : 14.6 mm Mini cassette thickness : 12.2 mm Based on this difference, it is differentiated within the cassette housing whether the inserted cassette is standard or mini. 1) When a mini cassette is inserted The reel disk position changes to the mini cassette position at the same time the cassette housing performs the intake movement. The reel change bracket (Fig. 4.2.3) located on the right side of the cassette housing is linked to the reel change plate (Fig. 4.2.4), so when the cassette housing intake movement occurs the reel change plate also moves, thereby changing to the mini cassette position.

2) When a standard cassette is inserted The cassette holder bar (Fig. 4.2.2) is pushed up for the amount of thickness differential in relation to mini cassette, and in conjunction the reel change bracket (Fig. 4.2.3) located on the right side of the cassette housing moves upward. As a result, the link with the reel change plate (Fig. 4.2.4) becomes free, and the reel disk becomes held in the standard position even while the cassette housing is undergoing the intake movement.

(2) Mini Cassette Incorrect Insertion Prevention Function
Sub Flap
Fig. 4.2.5 Sub Flap Sub flaps are attached on the cassette guide assembly located on the bottom end of the cassette housing door. These two sub flaps are designed to open when both are pressed simultaneously, and in the case of a mini cassette it is impossible for both to be pressed at the same time. So even if an inserted mini cassette touches against one of the sub flaps, the sub flaps will act as a brake to prevent erroneous loading of a mini cassette. CAUTION Even with standard cassettes, if the cassette is inserted skewed or diagonally offset in relation to the sub flaps, the sub flaps may not open and cassette insertion may not be possible. When inserting a standard cassette, be sure to insert so that the sides are parallel to the sub flaps.
(3) Intake/Eject Detection Two housing switches (HW, HW2) are equipped on the front left side of the main deck. (See Fig. 4.2.6) In the initial status in which no cassette is inserted (NO cassette mode), switch HW is pressed and switch HW2 is not pressed.

Table 4.2.1
: When a cassette is inserted, the HW switch goes OFF, which causes detection of cassette insertion. After this the motor begins intake action. Intake complete : When cassette intake is completed, in conjunction with the housing movement the main deck's switch lever slides, causing the MECHA board S3 (cassette switch) to be pressed, and intake completion is detected. (See Fig. 4.2.7) Eject : When ejecting the cassette, both switches HW and HW2 are momentarily ON, and eject completion is detected. And from here, it returns to the initial status of switch HW=ON, HW2=OFF.

4.2.4 Switches This is a description of how the various switches equipped on the mechanism operate, as shown in table 4.2.2. Switch name HW HW2 S1 (Mecha board) S2 (Mecha board) S3 (Mecha board) Operation Cassette intake detection switch Cassette eject detection switch Standard cassette detection switch SUP reel lock release switch* Cassette intake completion detection switch Table 4.2.2 Switches * Condition of SUP reel lock release switch operation : After cassette intake, tape is pulled out of the take-up side for loading, but when a virgin tape is inserted it switches over to pull out from the supply side since it is not possible to pull out from the take-up side. Immediately following tape intake completion, when the Begin sensor detects tape leader the cassette housing motor moves further to the loading side and, after the switches lever release the SUP brake, S2 is turned ON and brake release is detected.

Fig. 4.2.7 Switch Location 4.2.5 Reel motor The AG-DV2500 has adoped an independent one-reel motor, besides a capstan motor. As a result, quicker response when switching from Play to Reverse Search or Forward Search modes has been attained, greatly improving operability and the durability. And as shown in table 4.2.3 the speeds of capstan search and FF/REW are also accelerated. AG-DV2500 CAPSTAN Search SPEED FF/REW TIME Mini (DVM60) Standerd (DV270) Approx. 20X speed Under 75 sec. Under 200 sec. Table 4.2.3 4.2.6 Tension The AG-DV2500 have double tension control for supply/take-up. The AG-DV2500 uses double tension control to regulate the tension differential caused by winding and modes used, obtaining a uniform tape tension for stable tape transport.

4.2.7 Mode sensor The AG-DV2500's mode sensor adopts the variable resistor method (MECHA board VR1) which uses changes in resistance to detect the position of the mechanism. The changed voltage, brought about by changes in the resistance value due to mechanism position, is sent to DV/CPU IC302 to made to the A/D conversion. The mechanism position is judged by this. Mode sensor voltage 0.273 ± 0.03 V 1.314 ± 0.03 V 1.691 ± 0.03 V 2.111 ± 0.03 V 2.716 ± 0.03 V Mechanism position UNLOAD END position BRAKE position FAST position STOP position SEARCH position NO CASSETTE MODE FF/REW Modes in which tension band is used as brake for stopping FF/REW MODE STAND-BY OFF PLAY/REC/SEARCH/STAND-BY ON Mode

SYSTEM CONTROL
4.3.1 Outline The control system is comprised of the SYSCON CPU (IC2001) on the MAIN board assembly, and the VCR (MSD) CPU (IC302) on the DV/CPU board assembly. Both of these are connected by a bus called the MS_BUS, and communicate via serial data transfer . Communication type Communication speed Data length Bit order Clock generation source Data direction Clock synchronous serial communication 1.68 Mbps 8bit x 25 MSB head SYS CPU Full duplex Table 4.3.1 MS_BUS Communication Settings Fig. 4.3.1 MS BUS Connection 4.3.2 Communication specifications (1) SYSCON CPU turns the CS from "L" "H" and communication begins. (2) SYSCON CPU confirms that the BUSY terminal is "L", and transmits data at CLOCK1.68MHz as well as receives data from the VCR (MSD) CPU. (3) VCR (MSD) CPU also sends and receives data in accordance with CLK. However, if it is not yet ready for communication it sets the BUSY terminal to "H" and notifies the SYSCON CPU. (4) When the BUSY terminal is "H", SYS CPU skips the current communication and waits until the next block (400 µs later) to see if it is "L" and then starts communication. (5) After 25 Bytes are communicated, CS is set to "L" and communication ends. 4.3.3 Communication timing In synchronization with internal reference sync, communication takes place once every 16.6 ms (NTSC) or 20 ms (PAL). Byte interval is 400 µs. When necessary the contents of the communication are changed at the 1st2nd field.
