摘要： PROBLEM TO BE SOLVED: To provide an image reader that is provided with a cover member for a slot with a storage medium mounted thereon, which an operator does not open by mistake so as to avoid a defect due to occurrence of a read error thereby warranting a stable operation, in the case of reading an original by using the reader that is attachable to/detachable from a reader main body and reads the original through manual scanning when the reader is removed from the main body. SOLUTION: The image reader that is provided with a reader 6, which is attachable to/detachable from the reader main body 1, that reads an original through manual scanning, consists of the main body that is laterally long, a memory card that is inserted to/withdrawn from the main body, a data processing section that is capable of at least either or both of data reading and data writing, and a cover member that covers an insertion port. The cover member is provided with a cover opening prevention member in a freely opening/closing way with respect to the main body so as to prevent the cover member from being carelessly opened in this image reader. When the reader is mounted at a prescribed position of the reader main body, the cover member is supported and fixed in a closing state.

摘要： PROBLEM TO BE SOLVED: To provide an image forming device with excellent operability by acting a damper action only as required when a cover means is opened/closed so as to release the damper action in a final stage where a panel is locked to a device main body. SOLUTION: The image processing unit is provided with a damper mechanism that prevents the panel 7 from falling by its own weight from a standby position toward an operating position. An omitted gear section 57 is formed to a circular- arc gear 65, which deactivates an energizing force when the panel 7 is turned from the standby position to the operating position and generates the energizing force when the panel 7 is turned by a prescribed angle from the operating position to the standby position.

摘要： PROBLEM TO BE SOLVED: To manufacture a long-sized liquid ejection head having high reliability in the case where the liquid ejection head is manufactured by using an orifice plate made from silicon which is also a material of a device substrate. SOLUTION: An Al layer 22 to which patterning is applied is formed on a surface of a silicon substrate 21 whereby an orifice plate is formed. Dry etching is applied to the silicon substrate 21 by using Al layer 22 as a mask and then a hole 21a as a recess section having a depth greater than that of an ejection nozzle on the surface by 5-50 μm and a groove-like cutting line are formed to be disposed on positions corresponding to the ejection nozzle on the surface of the silicon substrate 21. Next, the rear face of the silicon substrate 21 is ground and abraded to thin the silicon substrate 21 and then the hole 21a is made to be a through-hole so that the ejection hole 3 on the silicon substrate 21 is formed and the silicon substrate 21 is divided into a plurality of orifice plates 16 by the cutting lines 21b. As a result, the orifice plate 16 having ejection hole 3 formed on the silicon substrate 21 is manufactured.

摘要： PROBLEM TO BE SOLVED: To secure a positioning accuracy between an orifice plate and a liquid channel of a head body. SOLUTION: An orifice plate 4 is set to be opposite to a holding member 10 having projections 11. The projections 11 of the holding member 10 are passed through corresponding dummy orifices 12a, whereby the orifice plate 4 is held by the holding member 10. In this state, leading end parts of the projections 11 project as projecting parts 11a from the dummy orifices 12a of the orifice plate 4. The projecting parts 11a are inserted and fitted to openings 16 of dummy liquid channels 6a of a head body 3. Then, a face of the orifice plate 4 where an adhesive resin 14 is applied, and a head body join face 15 of the head body 3 are brought in contact with each other while a highly accurate parallelism is maintained. The orifice plate 4 and head body 3 are joined by heating and pressure bonding. The holding to the orifice plate 4 by the holding member 10 is released, thereby separating the holding member 10 and orifice plate 4.

摘要： PROBLEM TO BE SOLVED: To provide an ink jet head having a high relative position accuracy between an ink discharge port of a nozzle plate and an ink chamber of a head body. SOLUTION: A poly-p-phenylene terephthalamide film 23 of a low coefficient of linear expansion considerably close to that of silicon is used for a nozzle plate 19. An amount of thermal expansion of the nozzle plate 19 when the nozzle plate 19 is thermally pressure-bonded to a head body is made small, and a relative position accuracy between an ink discharge hole 16 and an ink chamber can be enhanced. Moreover, an adhesion improvement film 22 of a polyamide resin or polyether amide resin is formed to a surface of the poly-p- phenylene terephthalamide film 23. An adhesion can be improved and, generation of deformation or positional displacement of the nozzle plate 19 can be restricted.
