1.
2. MECHANISMS The equipment is classified into the following mechanisms: ■ Transmitting Mechanism Feeding and scanning documents ■ Receiving Mechanism Feeding recording paper and printing data ■ Power Transmission Mechanism Switching the power transmission route ■ Sensors and Actuators 2.
2.1.2 Scanner The scanner uses a contact image sensor (CIS) unit which consists of an LED array illuminating documents, a self-focus lens array collecting the reflected light, a CIS PCB carrying out photoelectric conversion to output picture element data, and a cover glass on which a document advances. When the document passes between the white pressure roller and the cover glass, it is scanned.
2.2 Receiving Mechanism (Feeding recording paper and printing data) The receiving mechanism consists of the recording paper roll holder, anti-curl system (ACS) plate, platen, thermal recording head, automatic cutter, and sensors. (For details about the sensors, refer to Section 2.4.) The recording paper is routed on the ACS plate to the recording head which prints onto the heat-sensitive recording paper pressed by the platen according to received image signals.
2.3 Power Transmission Mechanism The equipment has a single drive motor whose power transmission route can be switched by the planetary gear train and the solenoid. This switching allows the equipment to function in four operation modes (recording, scanning, copying, and cutter driving modes). 2.3.1 Structure of the gear train The gear train consists of two groups of gears: one group on the drive unit and the other on the scanner frame ASSY.
Shown below is a gear train constructed by combining the drive unit and scanner frame ASSY. The motor rotation is transmitted via the planet gear 20B (C1) to the gear 16 (D) and via the gear 16/24 (K) to the separation roller gear (L).
2.3.2 Description of planetary gear system The planetary gear train consists of the sun gear 18/82, two planet gears 20, arm A, and arm B, as shown below. Stopper of arm A Motor gear Sun gear 18/82 Planet gear 20A Planet gear 20B Arm A Arm B Planetary Gear System If the motor rotates, the sun gear 18/82 rotates so that the rotational torque is transmitted to the engagement between the sun gear and the planet gears 20.
2.3.3 Power transmission for four operation modes Depending upon the solenoid ON/OFF state and the motor rotation direction, the planetary gear train switches the power transmission route for the four operation modes.
[1] Recording mode (Solenoid: OFF, Motor rotation: Forward) In the recording mode, the control electronics deactivates the solenoid. When the motor rotates in the forward direction, the clutch arm turns clockwise with the spring and its cutout X becomes engaged with the stopper of arm A. Once arm A is locked, the planet gear 20A (C2) will not be engaged with any other gear but simply idle.
[2] Scanning mode (Solenoid: OFF, Motor rotation: Reverse) Just as in the recording mode, the control electronics deactivates the solenoid in the scanning mode to lock arm A. The motor rotates in the reverse direction and the sun gear 18/82 (B) rotates clockwise so that the planet gear 20B (C1) transmits the rotation to the separation roller gear (L) and white pressure roller gear (O) via the several gears.
[3] Copying mode (Solenoid: ON➞OFF, Motor rotation: Forward) The control electronics at first activates the solenoid to release the stopper of arm A from the cutout X of the clutch arm while rotating the motor in the forward direction. Accordingly, the sun gear 18/82 (B) rotates counterclockwise so that both the planet gears 20B (C1) and 20A (C2) transmit the rotation; C1 rotation to the platen gear (H) and C2 rotation to the separation roller gear (L) and white pressure roller gear (O).
[4] Cutter driving mode (Solenoid: ON, Motor rotation: Reverse) The control electronics activates the solenoid to release the stopper of arm A from the clutch arm. When the motor rotates in the reverse direction, the sun gear 18/82 (B) rotates clockwise so that the planet gear 20A (C2) transmits the rotation to the cutter gear (Q) via gear P. Since the planet gear 20B (C1) is blocked by the section Y of the clutch arm, it is merely idle without engaging with any other gear.
The cutter gear (Q) is a two-stepped gear whose inside gear is a one-tooth sector gear. While the cutter gear (Q) rotates by one turn for one stroke of the upper blade of the cutter, the one-tooth sector gear slightly turns the platen gear (H) clockwise via the reverse gear (I) to feed the recording paper back into the equipment. This prevents the upper blade of the cutter from scratching the leading edge of the remaining paper.
2.3.4 Power transmission route Rotation of the motor gear is transmitted as shown below.
2.4 Sensors and Actuators This equipment has two photosensors and four mechanical switches as described below.

3.4 Control Panel PCB The control panel PCB and the main PCB communicate with each other by serially transmitting commands and data. The control panel unit consists of a gate array and LCD, which are controlled by the gate array according to commands issued from the FAX engine on the main PCB. The calendar clock is backed up by the backup circuit on the main PCB. The panel FPC is a flexible keyboard PCB which integrates the key matrix having rubber keytops.
3.5 Power Supply PCB The power supply uses the switching regulation system to generate DC power (+26.6V and +8V) from a commercial AC power supply. The +26.6V source is stabilized and fed to the motor and solenoid for feeding documents and recording paper or activating the automatic cutter, and also fed to the CIS LED array. It is also fed to the main PCB where the H26.6V source is generated. The H26.6V source outputs 26.6V only when the H26.6V ON/OFF control signal is High, for driving the recording head.
