Title: Optical deflecting scan device
Inventor: MIYAMOTO HIDEYUKI
IPC: G02B26/12
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To stop a rotor from falling axially easily at low cost without requiring any additional component by preventing an iron substrate itself from falling so that an axial fall is restricted by making part of the iron substrate overlap with a rotor. SOLUTION: When the rotor is inserted into a sleeve, a raised curved claw 6 is not bent yet and not an obstacle and it is bent after the insertion; and its overlap part B overlaps with the rotor, which will not fall axially. Even if the rotor is to fall owing to vibration or a shock at the time of transportation, it is stopped by the overlap part B from falling. Thus, the axial fall along the axis of the rotor is restricted by making part of the iron substrate overlap with the rotor, so the iron substrate itself serves as a stopper, no additional component is needed, and an operation process is only simple bending, thereby securely stopping the rotor of a scanner motor from falling axially with the simple and inexpensive constitution.

Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce the warpage derived from the difference of the linear expansion coefficients of a supporting member and a substrate by providing the supporting member comprising a ceramic baked product. SOLUTION: For jointing a substrate 3 with a supporting member 13 parallel and flatly, the supporting member 13 comprises a ceramic baked product instead of aluminum. In the case the substrate 3 and the supporting member 13 are bonded with an Ag-containing epoxy-based adhesive which is a heat transmissible adhesive by high temperature curing at 120-150 deg.C and then placed in an ordinary temperature, the array density of an ejecting energy generating element such as an electro-thermal converting element, provided on a substrate corresponding to an ink path can be higher.  Accordingly, even in the case heat generated from the electro-thermal converting element is increased in printing so that the temperature difference between the non-printing time and the printing time becomes larger in the substrate and the supporting member, the warpage derived from the difference of the coefficients of linear thermal expansion of a supporting member and a substrate can be reduced. Therefore, the supporting member 13 and the substrate 3 can be jointed parallel and flatly.
