Abstract:
A reading pen for reading text has an elongate casing with a reading opening (3) formed in one end thereof, a printed circuit board (5) which is arranged inside the casing, light-emitting diodes (7a, 7b) arranged inside the reading opening and adapted to illuminate the text that is to be read, and a light-sensitive sensor (9) arranged inside the reading opening and adapted to read the illuminated text. The printed circuit board (5) has an end portion at said one end of the casing. The end portion essentially corresponds to the form of the casing. The light-emitting diodes (7a, 7b) and the light-sensitive sensor (9) are arranged on said end portion.
Abstract:
An integrated image module for a document scanner includes a one piece die cast housing having a datum element and a support element. An imaging sensor array is enclosed in the housing. An array bias element urges the imaging sensor array against the datum element to provide accurate placement of the sensor array relative to the housing. A transport mechanism is attached to the housing so that the position of the transport mechanism accurately corresponds to the position of the imaging sensor array. The lens and the lamp for illumination are also attached to the housing so that the primary components of the imaging portion of the scanner are contained in a single module.
Abstract:
Procédé de fixation sur le bâti (1) d'un appareil tel qu'un télécopieur, d'une carte support (2) d'un détecteur optique à circuit à transfert de charges. Il comprend l'étape consistant à appliquer ladite carte sur une surface d'appui (3) dudit bâti à l'aide d'un organe d'appui (4) mobile sensiblement perpendiculairement au plan de ladite carte.
Abstract:
An optical scanner includes a light source for projecting a light beam, a deflector for deflecting the light beam, a reflective member for reflecting the light beam toward a target, a contact member, and a pressing member. The reflective member includes a reflective plane and a rear plane opposite the reflective plane. The contact member contacts one of the rear plane of the reflective member and a first lateral plane perpendicular to the reflective plane to position the reflective member in place. The pressing member presses the reflective member against the contact member and includes a first pressing portion to press the reflective plane of the reflective member and a second pressing portion to press a ridge of the reflective member at which the reflective plane and a second lateral plane opposite the first lateral plane and perpendicular to the reflective plane of the reflective member meet.
Abstract:
An image reading apparatus includes a drive unit that is mounted on a carriage having an image reading sensor, which is moved with respect to an original, mounted thereon and moves the carriage. The drive unit includes: a motor; a gear train for transmitting rotation of the motor so as to move the carriage; an encoder sensor for reading a code wheel fixed to a rotary shaft of the motor; and a support member for holding the motor. The encoder sensor is urged against a part of the support member by a resilient member, to be thus fixed to the support member.
Abstract:
A mounting structure for an inverter circuit board for a light source lamp of an image reader in which mounting means for mounting the inverter circuit board for a light source lamp of an image reader onto a carriage is located to be operated from the direction in which the carriage moves in one embodiment. The inverter circuit and heat dissipation plate are removably mounted to an end of the full rate carriage. In another embodiment, the circuit board is mounted to the top for access from above the carriage.
