The system for showing a film according to the preferred embodiment 5 of the present invention further comprises a cable drum (not shown) for introducing a general electric power line into the vehicle. The cable drum may be used instead of the small generator in the vehicle 100.

Having described the vehicle having a system for showing a film according to the preferred embodiment of the present invention in detail, the 0 operation of the vehicle can be understood as follows.

Referring to FIGS. 5a and 5b, if an operator of the vehicle wants to show a general film to a number of attending spectators, the first screen 152 attached to the front wall 120 of the cinema box 120 may only be used for showing that film. Alternatively, if the operator wants to show a three- 5 dimensional film to a number of attending spectators, the second screen 159 of the projection screen 150 may be used together with the first screen 152 for showing that film. For this purpose, when the operator pulls downwards the string extending from the second screen 159 of the projection screen 150, the second screen 159 wound around the winding rod 158 begins to be o downwardly exposed externally to thereof through the hole 154a of the housing 154. At this time, the winding rod 158 rotates within the housing 154. Due to the rotation of the winding rod 158, the second screen 159 is exposed externally to the winding rod 158 so that it can fully cover a front surface of the first screen 152. Then, the operator holds the string extending from the second 5 screen 159 and then lets it free. As a result, the winding rod 158 stops the rotation due to operation of a device (not shown) for stopping rotation of the winding rod 158. Consequently, the first screen 152 and the second screen 159 overlap with one another.

Continuously, the operator may select at least one among the image record films such as videotape, a digital versatile disk, etc. After selecting proper films to be displayed, the operator fits one of the films into the first projector 160 installed at the upper portion and the second projector 162 of the angle controller 170. It will readily be understood that using the first projector 160, which always spreads on the front wall 126, may show a general film.

After fitting the film into the first projector 160, the operator operates the second projector 162 so as to exactly project an image on the first screen 152 and the second screen 159 of the projection screen 150. Next, the operator controls the tilting angles of the second control plate 178 and the first control plate 174 in sequence.

In order to control the tilting angle of the second control plate 178, the operator loosens the nuts 177 threaded onto the bolt rods 176 of the upper and the lower portions of the second control plate 178. Thereafter, the operator harmonizes the image-projecting angle of the second projector 162 installed at the second control plate 178 with the first and the second screen 152,159 of the projection screen 150. At this time, the operator tightens the screw so as to hold the second control plate 178. Next, in order to control the tilting angle of the first control plate 174, the operator loosens the nuts 177 threaded onto the bolt rods 176 of the upper and the lower portions of the second control plate 178. Thereafter, the operator harmonizes image-projecting angles of the first projector 160 installed at the first control plate 174 with the first and the second screen 152,159 of the projection screen 150. At this time, the operator tightens the screw so as to hold the first control plate 174. As a result.-after the disharmony has been corrected, another treatment is required for showing the film.

In order to permit a number of attending spectators to come in and to go out, the operator opens the main gate 130 and the auxiliary gate 132. At this time, the main gate 130 and the auxiliary gate 132 may be manually or automatically opened. As shown in FIGS. 8 and 11 , if the operator opens the auxiliary gate 132, the retaining room 230 formed at the rear side of the loading plate 142 is also opened. After opening the retaining room 230, the operator pulls out the ladder 220 from the retaining room 230. During this procedure, the guiding rollers 228 rotatably installed at the locking stage 226 of the ladder 220 slide along the guiding rails 232 of the retaining room 230. In other words, the guiding rollers 228 of the locking state 226 may be operated in conjunction with the guiding rails 232 of the retaining room 230 so as to permit the ladder 220 to come in and to go out. The locking stage 226 of the ladder 220 is laid at the utmost outer periphery of the retaining room 230, and one end of the vertical bar 222 of the ladder 220 is contacted with the ground, respectively.

Some of the attending spectators would come into the cinema room through the main gate 130 and then would sit on the seats. Other attending spectators would come into the cinema room through the auxiliary gate 132. When some of the attending spectators come into the cinema room through the auxiliary gate 132, they go through the horizontal bar 224 of the ladder 220 and the auxiliary stairs 144 of the loading plate 142 in sequence. If all attending spectators come into the cinema room, the main gate 130 and the auxiliary gate 132 are closed in order to close the cinema box 120. Thereafter, the operator turns on relatively bright illuminators among the illuminators 190 so as to brighten the interior of the cinema box 120. Then, other illuminators 190 are turned off except for relatively dark illuminators among the illuminators 190. After performing this illuminating work, preliminary works for showing a film have been completed.

Under this state, the operator makes the first projector 160, the second projector 162 and the sound facilities 180 to be operated so as to display a film. As previously mentioned, it is possible to control a temperature of the interior by operating the cooling and heating device 200 in accordance with an exterior weather condition. Further, it is possible to provide the attending spectators with fresh air by operating the ventilation device 240. Although an example of displaying a film has been explained above, it is possible to perform an image education by showing an educational image or to see and hear a satellite broadcasting by using the satellite antenna 250 installed at the upper portion of the upper wall 122 of the cinema box 120.

As described above, the vehicle having a system for showing a film according to the preferred embodiment of the present invention is capable of providing the audience with a movie and an educational image, which can be used for publicity activities, at places such as a small town or a remote and secluded place in which the vehicle can get there. Furthermore, it is possible to display a three-dimensional film. In addition, since the cooling and heating device, and the ventilation device may be operated in the vehicle according to the preferred embodiment of the present invention, it is possible to provide the spectators with fresh viewing condition. Furthermore, since some beautiful interior decorations may be provided on the interior wall of the vehicle, it is possible to provide the spectators with a beautiful viewing environment. In addition, it is possible to receive the satellite broadcasting by using the satellite antenna. Since the display device is installed at one outer side of the cinema box, people may easily perceive the information relating to display of movies and educational information.

While the present invention has been particularly shown and described with reference to particular embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be effected therein without departing from the spirit and scope of the invention as defined by the appended claims.
