When the button is pressed down, the said illuminator gives off rays and projects the pictures and characters on the film by means of so as to produce advertising effectiveness.  
      In order to facilitate the installation and use of the pen, the said illuminator of this invention is embodied as a LED. The back end of the said connecting tube is equipped with an installation tube, and the connection between the connecting tube and the installation tube is a detachable one; the said lens is installed in the back end of the installation tube by means of a snap ring; the said film with pictures and characters is installed in the front end of the connecting tube by means of a snap splicing sleeve, and the connection between the snap splicing sleeve and the installation tube is also a detachable one.  
      The said detachable connections of the present invention are the screwed ones for facilitating the installation between the penholder and the connecting tube, the connecting tube and the installation tube, as well as the snap splicing sleeve and the installation tube.  
      The invention has the following advantages: it can realize advertising effectiveness through the projection produced by the illuminator, the lens and the film with pictures and characters, which are installed in the connecting tube.

As shown in  FIG. 1  and  FIG. 2 , the battery  4 , the button  6  and the LED  5  are arranged sequentially and form a circuit in the front end of the connecting tube  3 , and the button  6  is installed in the sidewall of the connecting tube  3 ; the installation tube  11  is fixed at the back end of the connecting tube  3 . The connection between the connecting tube and the installation tube is the screwed one. The lens  8  is arranged in the back end of the installation tube  11  by mean of the snap ring  9 . The film  7  with logo between LED  5  and lens  8  is installed in the front end of the installation tube  11  by mean of the snap splicing sleeve  10 , and the connection between the snap splicing sleeve  10  and the installation tube  11  is the screwed one. In this way, the LED  5  can project the logo through the film  7  and the lens  8  sequentially.  
      While in operation, press the button  6 , LED  5  gives off rays and projects the character of the logo printed on the film  7  with logo by lens  8 , then come out the image shown in the  FIG. 3 . When the parts needs detaching or replacing, the following such as the connection tube  3  and the penholder  2 , the installation tube  11  and the connecting  3 , or the snap splicing sleeve  10  and the installation tube  11  can be detached.
