摘要： PROBLEM TO BE SOLVED: To lower the heat-resistant temperature of a luminous flux control means for reducing irregular intensity and irregular color caused by the vignetting at the edge of a projection lens, and also to restrain the lowering of contrast caused by stray light. SOLUTION: The projection type display device is equipped with: a light source; a liquid crystal panel; an integrator comprising a first lens array and a second lens array and uniformly illuminating the liquid crystal panel; the projection lens for enlarging and projecting an optically modulated image by the liquid crystal panel onto a screen; and the luminous flux control means for controlling luminous flux made incident on the integrator from the light source between the light source and the integrator. The luminous flux made incident from the peripheral part of the reflection mirror of the light source out of the luminous flux made incident on the integrator from the light source is intercepted by the luminous flux control means.

摘要： PURPOSE:To improve the workability and safety, and to reduce a maintenance cost at the time of maintenance, and to attain a mass production of a projecting part unit and the mounted device by providing a caster, handle, and non-slip member at the mounted device of the projecting part unit. CONSTITUTION:A mounted device 8 of a projecting part unit 9 is equipped with a caster 8a, hole 8b, handle 8c, rubber leg 8d, and non-slip member 8e. In this case, one of a front cover 5, side cover, and rear cover 7 is detached from a lower part cabinet so that the projecting unit 9 can be drawn from any back-and-forth-and-right-and-left direction of the lower part cabinet. At the time of laying the mounded device 8 down on a floor face 12, a force 10 is added to the handle 8c in an arrow direction. At that time, the non-slip member 8e is abutted to the floor face 12. Thus, the projecting part unit 9 can be easily turned into almost a horizontal and vertical state, so that the projecting part unit 9 and the mounded device 8 can be used for the various types of projecting display devices.

摘要： PURPOSE:To tilt a screen with a relatively small force and to prevent it form moving at the time of plotting input by providing a supporting member which projects from a main body when a display part is tilted and supports the display part in the tilt state form behind. CONSTITUTION:When multi-business equipment is used as a personal computer, data are inputted on its keyboard 4 and the liquid crystal display 1 is set at a vertical position so that the display is easy to see. When a plotting communication is made by using a stylus pen 2, the liquid crystal display 1 is tilted greatly around a spring damper 7 as a fulcrum so that a fulcrum so that a figure is easily drawn. At this time, a supporting part 8 is drawn out of the main body 3 and locked and the force that the liquid crystal display 1 receives when the plotting is inputted with the stylus pen 2 is supported by the spring damper 7 and support part 8. Consequently, the display can be tilted with a relatively small force and fixed not to move at the time of the plotting input.

摘要： PURPOSE:To confirm the upper and lower limit positions of tilting and to increase the sensation of tilting operation by forming plural projecting part or recessed parts which can be clicked with recessed or projecting parts formed on a connecting arm. CONSTITUTION:When a display device D is tilted from a use state for a personal computer to a drawing communication state, the device D is pulled and raised to disengage the recessed parts 14 and projection parts 15 from each other, the device D slants increasing in tilt angle gradually while moving down, and the connecting arm 9 rotates anticlockwise. When the device D reaches its tilt lower limit position, the recessed parts 14 of the arm 9 engage the projection parts 16 of the main body 1. Further, when the device is tilted from the drawing communication state to the use state for the personal computer, the device D is elevated and rotated to the upright altitude, the recessed parts 14 are disengaged from the projecting parts 16 and the arm 9 rotates clockwise. Then, when the device D reaches the tilt upper limit position, the recessed parts 14 engage the projecting parts 15 again.

摘要： PURPOSE:To hold back the force of spring back by bending an insulation sheet so that it may be box-shaped and installing some device like hook on the side of the box and a hole into which the hook may be seized. CONSTITUTION:An insulation cover 1 which comprises an insulation sheet bent in a box shape is mounted on a circuit substrate 7. The side 4 is provided with a projected part 5 and a fit-in section 6 which is inserted into a long hole 3 provided on the circuit substrate 7. Each side of the insulation sheet 1 tends to extend outward by the force of spring back, but the projected part 5 is hooked with the L-shaped hole 3 so that it may be further fitted-in, thereby preventing the extension of each side of the sheet. At the same time when external force is applied to the side 4 of the insulation sheet 1 inwardly, the side 4 is protected from the inward deformation induced by external force since the long hole 8 is installed to the circuit substrate 7 and the projected part 6 provided on the side 4 of the insulation sheet 1 is fitted into the hole 8. It is, therefore, possible to prevent the extension of each side.

摘要： PURPOSE:To prevent the invasion of a flux by covering an insertion port when a flow soldering is carried out. CONSTITUTION:A female side connector 8 is installed to a substrate. At that time, a hole for a terminal 6 and a hole for an insertion port 2 are provided at the substrate. Even though an insulator flux comes up from the hole for the insertion port 2 of the substrate 3 at the flowing, the insertion port 2 of the female side connector 8 is closed and the flux does not attach to a pin connection 5. And when a male side connector pin 4 is inserted to the insertion port 2, an elastic pawl 1 of the connector 8 escapes, when, the insertion port 2 is opened. As a result, the pin 4 is inserted and connected to the connection 5.
