Problems solved by technology

However, in the above-mentioned structure, since the door is engaged with only one end of the arm, a large torque is easily generated at the one end when an external force is applied, and the door may be opened and closed against the operator's intention. sex

Deformed example 1

[0093] In the liquid crystal projector described above, the arm 22 is arranged to overlap the door 21 at the open position where the opening 11 is opened, but may be arranged to overlap the door 21 at the closed position where the opening 11 is closed. Specifically, in the liquid crystal device 2 described above, the opening 11 is disposed above the installation table 24 . The structure of this modified example can also obtain the same effect as that of the above-mentioned liquid crystal projector.

Deformed example 2

[0095] In the above-mentioned liquid crystal projector, the protrusion 223 constituting the engagement mechanism is disposed on the front end 222 of the arm 22, and the engagement groove 213 is disposed on the other side end 212 of the door 21. However, the protrusion 223 223 is disposed on the other side end portion 212 of the door 21 , and the engaging groove 213 may be disposed on the front end portion 222 of the arm portion 22 .

[0096] In addition, in the liquid crystal projector described above, the engaging groove 213 extends perpendicular to the sliding direction 90 , but may extend obliquely with respect to the sliding direction 90 .

[0097] The engagement mechanism of this modified example can also move the door 21 straight and stably in the sliding direction 90 .

Deformed example 3

[0099] In the above-mentioned liquid crystal projector, the convex portion 273 of the soft locking mechanism is formed on the latch plate 271, and a pair of concave portions 274, 275 are formed on the arm portion 22, but the convex portion 273 may also be formed on the arm portion 22, and A pair of recessed portions 274 and 275 are formed on the latch plate 271 .

[0100] The liquid crystal projector of this modified example is the same as the above-mentioned liquid crystal projector, and the arm portion 22 can also be softly locked by the soft locking mechanism at the closed position and the open position.

Abstract

The inventin provides an electronic device with opening / closing door arranged in the shutter system for preventing the opening and closing of the door in the case that the intention of the operator isagainst due to external force. The electronic device with an opening / closing door of the present invention includes a device body in which an opening is defined, a shutter system capable of coveringand exposing the opening, and a loosely fixing mechanism. The shutter system includes a door capable of moving back and forth, an arm swingably supported by the device body and having a front end engaging with the door, a motor for opening and closing the door by driving the arm, and a controller for controlling the operation of the motor. The controller is capable of switching the function of themotor between an electric motor and an electric generator. The loosely fixing mechanism is linked to the arm of the shutter system, and loosely fixes the arm when the door is placed at the open position, while loosely fixing the arm when the door is placed at the closed position. The controller causes the motor to function as an electric motor in the process of opening and closing the door, whilecausing the motor to function as an electric generator when the door is loosely fixed at the open position or at the closed position.

Description

technical field [0001] The invention relates to electronic equipment with an opening and closing door such as a liquid crystal projector with a shutter device. Background technique [0002] Conventionally, in a liquid crystal projector that projects an image on a screen, it is necessary to temporarily suspend image projection on the screen while a light source for image projection is turned on. For example, in a liquid crystal projector disclosed in Patent Document 1 listed below, a shutter device composed of a plurality of shutter parts is arranged between an optical device such as a color synthesis prism and a light source, and the plurality of shutter parts are rotated to close the shutter, Thereby, passage of light can be blocked temporarily. [0003] However, in the liquid crystal projector disclosed in Patent Document 1, since it is necessary to rotate a plurality of shutter parts, the structure of the shutter device is complicated. Therefore, consider having Figure...
