Abstract: In a structure for attaching a lamp cover (61) to an upper case (21), when a part (631C) of a fitting (631) is pressed downward by a pin member (P) to release engagement of the lamp cover (61) with the upper case (21), the lamp cover (61) is biased toward outside of the exterior case, so that the lamp cover (61) can be opened with one pressing action of with the pin member (P) and operation thereof can be facilitated.

Abstract: A handle opening is formed by cutting a part of an exterior case, a rising portion is formed by bending the case toward inside of a casing along cutting periphery of the handle opening, a shaft member for rotatably supporting the handle is inserted to an attachment hole formed on the rising portion, and a screening member for covering the handle opening from the inside of the casing is engaged to the rising portion, thereby covering the gap between the handle and the rising portion by the screening member to improve appearance after attaching the handle.

Abstract: A centrifugal fan (50) is provided around the light source of the projector and an exhaust duct (51) is connected to the centrifugal fan with at least one of bent portion (52) for bending exhaust stream from the centrifugal fan being formed on the exhaust duct. Since the centrifugal fan for exhausting air can be disposed at a position remote from the exhaust hole, the noise generated from the projector can be reduced even when the size of the cooling fan is increased.

Abstract: Camera module device (1), which can be mounted onto a camera main body and that is used in a state in which it is mounted onto the camera main body, is provided with a circuit for generating data to be written, and thus camera main body (2) need not be equipped with a function for generating data to be written or a communication function for sending the generated data to camera module device (1). Camera main body (2) simply issues pulse signal X1 for a write instruction, and then data is generated by camera module device (1). Therefore, the camera main body can be made inexpensively. Furthermore, camera module device (1) is provided with a self-check function, and signal RD1 from camera main body (2) places this function in the active mode during photographic film loading. In this mode, circuit board (16) reads the data that has actually been written and determines whether or not the writing operation was performed correctly based on the comparison result of comparison circuit (162).

Abstract: In data projection device, a liquid crystal display panel which forms a data pattern, such as the date, as a translucent area, is positioned in the middle of an optical path located between an ambient light inlet and a photographic film. A data projection shutter which can work in conjunction with a photographic shutter, is positioned on the side of the film relative to a liquid crystal display panel. Manual projection optical path switching device is arranged in a data projection shutter and switches between the state in which the data projection shutter operates in conjunction with the photographic shutter and a state in which an interlock between the data projection shutter and the photographic shutter is released.

Abstract: Camera image data transfer device 1 of the present invention allows for the assembly of its components, with one component on top of another from the bottom up in one direction: liquid crystal display device for data transfer 6 is mounted in recess 28 on the inner side of first base 2; then, circuit board 5 and second base 3 are placed on top of it in this order; next, liquid crystal monitor display device 7 is mounted on the outer side of the second base; and finally fixture 8 securely fixes the display device to the second base. The whole device is fixed by securing the ends of dowels 21-27 to second base 3 with going through the entire structure and being extended from first base 2. Thus, the structure of the present invention facilitates assembly and produces fewer defects.
