4 Mechanical and Electrical

4.1Illumination Mechanism

4.1.1 Overview

The Illumination Mechanism efficiently uses the light produced by the Projection Lamp to supply the most suitable amount of light for the projection of the Microfilm. This amount of light is determined by the size of the Microfilm and by the magnification ratio of the Lens selected for use.

4.1.2 Projection Lamp (LA1)

A DC20V, 150W halogen Lamp is used as the light source for the reader and printer functions.

The Projection Lamp is integrated with a Lamp Reflector which is a polygon mirror to ensure even illuminance.

NOTE

1.Whenever the Projection Lamp Unit is removed, Make sure that the Power Switch is turned OFF.

2.Never touch the Projection Lamp immediately after it is turned OFF: be careful, it is extremely hot.

3.Do not touch with hand or dirty with grease the surfaces of the Projection Lamp and Lamp Reflector.

Projection Lamp (LA1)

37

4.1.3 Projection Lamp Voltage Control Circuit

The intensity of the light emitted by the Projection Lamp is adjusted to a level optimum for the image density by controlling the voltage applied to the Projection Lamp.

The exposure data optimum for film image density is determined through auto exposure data sampling made during prescan.

This exposure data is output as a Projection Lamp clock from the Main Control Board (PWB-BB) to the Projection Lamp Regulator (PU2).

The ON and OFF periods of the Projection Lamp clock extending 606 ???sec. are varied to control the Lamp voltage. The longer the OFF time, the

higher the Lamp voltage.

Projection Lamp clock

38

4.1.4 Thermostat (TS1)

To avoid any of the troubles accompanying an excessive rise in the temperature inside the machine caused by a failure of the Cooling Fan to dissipate heat produced by the Projection Lamp, there is a Thermostat installed at the back of the Projection Lamp.

When the ambient temperature of the Projection Lamp exceeds 122??C the Heat-Sensitive Plate expands pushing up the Pusher Pin, which in turn cuts off the current to the Projection Lamp Circuit.

The Circuit is reset by pushing the Reset Pin.

4.1.5 Condenser Lens

 Overview

Not only must the amount of light projected onto the Screen or CCD remain even despite changes in the microfilm or magnification ratio, but also the light coming from the Projection Lamp must be efficiently condensed. To accomplish this, the machine is equipped with two Movable Condenser Lens: one convex and one concave.

 Movable Condenser Lenses

The Brightness Shift Lever is moved manually according to the magnification of the Projection Lens being used so that the Movable Condenser Lenses are moved to the set position. The set position is color- coded, TYPE 1 to 3, each defined by a corresponding magnification of the Projection Lens.

 Condenser Mirror

Light from the Projection Lamp after having passed through the Movable Condenser Lenses strikes this Mirror and is reflected onto the Fresnel Lens.

 Fresnel Lens

The Fresnel Lens, which is an acrylic plate with stepped setbacks, ensures even illuminance from the Lamp.

4.1.6 Projection Lens

The Projection Lens enlarges the image of the Microfilm and projects it onto the Screen or CCD.

Each Projection Lens comes in a unit. The Focus Ring and Zoom Ring of the Unit are used to bring the image on the Screen into focus and enlarge or reduce it, respectively.

The Prism Lens for image rotation is installed in the Prism Holder fixed to the machine.

The Projection Lens Unit is slid into position in the Lens Holder of the machine. To insert the Unit, raise the Prism Holder and, at the same time, push it into position.

When a Projection Lens Unit is installed, the Brightness Shift Lever must be moved as required according to each magnification.

4.2.2 Auto Image Rotating Motor (M5) Control Circuit

When the Auto Image Rotating Knob is at the home position (center), voltage at PJ2C-2 is set at DC2.5V and the Auto Image Rotating Motor (M5) remains stationary.

PJ2C-2 reads fluctuations of the input voltages as the Auto Image Rotating Knob is turned, there by determining the direction of rotation of the Auto Image Rotating Motor.

42

4.3Optical Section

4.3.1 Overview

The basic function of the Optical Section is to project an enlargement of the image on the microfilm onto the Screen when in the Reader Mode and onto the CCD when in the Scan Mode.

There is a unique light path formed in each of these modes.

The light path formed in the Reader Mode is called the Reader Path and that formed in the Scan Mode is called the Scan Path.

Each light path is formed by two Reader Path Mirrors and three Scan path Mirrors.

1st Reader Path Mirror

2nd Reader Path Mirror

2nd Scan Path Mirror

Reader

Path

43

4.3.2 Reader Path

The Reader Path is established when the Power Switch is turned ON and remains formed except during a scan movement.

The image on the microfilm is projected onto the entire area of the Screen by means of the two Reader Path Mirrors.

The light path between the Projection Lamp and Screen measures 1,293mm.

4.3.3 Scan Path

When in the Scan mode, the 1st Scan Path Mirror moves to a position that will block the Reader Path.

It then turns to direct the film image through the four Scan Path Mirrors onto the CCD so that it can read the image data in the sub-scanning direction.

The light path between the Projection Lamp and CCD measures 1,298mm.

44

4.3.4 Scan Table Drive Mechanism

The Reader Path is switched from the Printer Path, or vice versa, by moving the Scan Table to the respective positions.

The Scan Table is driven from the Scan Table Drive Motor (M2). The direction and speed of rotation of the Scan Table Drive Motor (M2) are controlled by the outputs from pins 3, 4, 5 and 6 (??A, ??B, ??A, and ??B) of PJ5T on the Motor Drive Board (PWB-T).

Reader Position

Reader Position

Sensor (PC3)

Scan Position

Sensor (PC4)

To switch from the Reader Path to the Printer Path, the Scan Table Drive Motor M3 is energized there by moving the Scan Table toward the Printer Position.

The Scan Table at the Reader Position is detected by the Reader Position Sensor (PC3) and that at the Printer Position is detected by the Scan Position Sensor (PC4).

It takes less than 1.3 sec. for the Scan Table to move from the Reader to Printer Position.

45

4.3.5 Scan Mirror Motion Control

The motion of the Scan Mirror is controlled by the Scan Lever and Shaft as the Shaft is driven by the Scanning Motor (M1).

The Scan Mirror scans the image of the microfilm at a speed 1/631.6 of the Scanning Motor (M1).

Once the prescan motion is initiated, the leading edge of the image is synchronized with that of the paper, and the completion of the scan motion is detected, by the Scan Start Position Sensor (PC1) which are activated and deactivated by the cutouts in the light blocking Lever.

Scan Mirror first makes a prescan motion for reading the data before making the scan motion.

The starting position for the prescan or scan motion is determined by particular states of these sensors, blocked (activated) or unblocked (deactivated), as detailed below.

46

4.3.6 Mirror Scan Motor (M1) Control Circuit

Drive of the Scanning Motor (M1) is controlled by the signals which are input to the Motor Driver Board (PWB-T) from the Main Control Board (PWB-BB).

These signals determine the direction (forward or backward) and speed of rotation of the Scanning Motor when the Scan Mirror makes a prescan and scan motion.

These signals cause the Scanning Motor drive pulses to be output from the pins (A, B, A, B) of the Motor Driver Board (PWB-T), which turns the Scanning Motor (M1).

47

4.4CCD Section

There are five 960-pixel CCD sensor chips arranged in a zigzag as illustrated below.

4.6Auto Masking

4.6.1 Overview

If a print is made from an image that is projected smaller than the Markers on the screen, the non-image areas of the film result in black bands running around the image on the print.

The Auto Masking Function Automatically detects the non-image areas of the film.

4.6.2 Masking Area Detection

The CCD Board (PWB-A) is detects the density of the film image.

If Auto Masking is selected on the control panel, the CCD Board (PWB-A) detects the masking area (By measuring the intensity of light) while the Scan Mirror makes a prescan motion.

4.9.2 Operation

When printing, the scanner occupies the printer. When the print is ended, the scanner opens the printer.

The scanning begins when the start key to the other scanner is pushed. And waited that the printer is opened while storing the image in the memory in the scanner while printing.

Meanwhile, scanner is shown for the Multi-print display to blink, and not to accept the next scanning.

If the print of the preceding other scanner ends, and the printer is opened, the image stored in the memory as here occupies the printer is printed.

A job that is waiting to be printed can be cancelled by pressing the Clear/ Stop key on the scanner that sent the job.

(Push the Clear/Stop Key three times when you used the print reserve function)

As a result, the print job is deleted from the memory and that scanner's Multi-print Display stops blinking and stays lit.
