Abstract:
A scanning head comprises a support member (2) for supporting the head in pressing contact with a platen (26). The support member has lower strength portions (A) spaced longitudinally of the head, and higher strength portions (B) alternate with the lower strength portions. The support member is easily bendable at the lower strength portions, and the higher strength portions are urged by springs (27) toward the platen. Thus, the head can come into intimate pressing contact with the platen even if the surface flatness of the support member as a whole is not strictly realized.

PROBLEM TO BE SOLVED: To restrain a gap from being formed between a luminous body and a light guide body even when a strain develops in the device body.SOLUTION: An image reading device of the present invention comprises: an optics enclosure 41; a light emission side plate 31b fixed to the optics enclosure 41; a luminous element row 31a, provided on the face on one side of the light emission side plate 31b, which emits the light to be irradiated upon a document; a light guide body 32, provided at a position opposed to the light emission side plate 31b across the luminous element row 31a, which guides the light emitted from the luminous element row 31a through the inside thereof; a spring 79; an axis 75 fixed to the optics enclosure 41; a bracket 73 which, upon receiving a force from the spring 79, is pressed in a direction heading from the light emission side plate 31b toward the light guide body 32; and a lever 77 which, while receiving reaction from the axis 75 as the bracket 73 is pressed, presses the light guide 32 against the luminous element row 31a.
Abstract:
PROBLEM TO BE SOLVED: To provide an image reading apparatus that reads an image from an original on a contact glass by means of an image sensor housed in a carriage and that maintains the quality of image reading while being downsized.SOLUTION: A multifunctional device 1 slides an image sensor 20, which is housed in a sensor housing portion 31, along a slide shaft 25 together with a carriage 30 so as to read an image from an original on a contact glass 16. The carriage 30 is attached to the slide shaft 25 through a shaft holding portion 38 provided at the longitudinal center thereof, and is allowed to be swung around the slide shaft 25. The carriage 30 has a first tapered end 32, and a first opening 34, formed at one end thereof where a first holder member 40 and springs 50 are attached. The carriage 30 has a second tapered end 33, and a second opening 35, formed at the other end thereof where a second holder member 45 and springs 50 are attached.
Abstract:
PROBLEM TO BE SOLVED: To provide a downsized optical scanning apparatus, and to provide an image forming apparatus which uses the scanning apparatus. SOLUTION: The optical scanning apparatus includes a plate member 11, having a rotating shaft and a reflecting surface 24 which deflects and scans a laser beam 10 emitted from a light source, by the reflecting surface 24 perform reciprocative turning about the rotating shaft; an actuator 14 for driving the plate member 11; an fθ-lens 3 for focusing the laser beam 10, deflected and scanned by the plate member 11 on the surface of a photosensitive drum 32; and an optical box 31 for housing the plate member 11, the actuator 14 and the fθ-lens 3. The actuator 14 is provided closer to a side, to which the laser beam 10 is reflected by the reflection surface, than to the reflecting surface 24 of the plate member 11. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a mounting structure which can regulate the position of a mounting part, i.e., the bending angle of a wiring substrate without using a jig or the like and can arrange the mounting part at an optional position without interrupting downsizing of the mounting structure and a mounting product to a mounting structure. SOLUTION: The mounting structure 10 includes a box wherein a bendable wiring substrate 11 is placed. When the wiring substrate 11 is bent, mounting parts 12 and 13 mounted to the wiring substrate 11 are brought into contact with each other, or a mounting part mounted to the wiring substrate 11 and the wiring substrate 11 are brought into contact with each other, so that the bending angle θ of the wiring substrate 11 is regulated and an angle holding means is provided to hold the contact state.

Abstract:
A housing includes a first portion and second portion. Each of the first and second portions supports a mirror and are connected and prevented from independent movement through a cover glass plate. The connection between the portions of the housing reduces the amount of angular change of mirrors within the housing resulting from a change in temperature, and thereby reduces the amount of displacement of a reading point of an image receiving element during the temperature change. The reading point is projected along an optical path including multiple reflections from the mirrors. A first connection device tightly fits the cover glass plate between the first and second portions of the housing, and a second connection device adheres the cover glass plate to the first and second portions of the housing.
