    • A slide projection overlapping apparatus comprising at least two slide projectors associated with a switching device capable, upon advent of a projection terminating signal thereto, of shifting the connections between the slide projectors enabling discontinuity to be avoided in the projections of successive views at transition from the projected slide projector to the next one. The switching device is provided with delay means for delaying by predetermined time intervals the projection terminating signal to be given to at least one of the said slide projectors with the lamp circuits which are intended to be opened and closed in predetermined sequence.

    • The present invention refers to equipment to synchronize the pictures with the sounds, with which equipment the difference between the pictures of a slide projector or the like and the sounds of the corresponding tape recorder is corrected. The invention is characterized in that at the position of the sound recording tape corresponding to N pictures, a signal corresponding to the picture and on the Nth picture a signal corresponding to the sound recording tape is provided, whereby by means of the output of an electrical circuit to detect the coincidence of both signals, the switching over to the next picture or the sound recording tape is carried out. At the position of the sound recording tape corresponding to the first or the last picture, a signal corresponding to a picture and on the first or the last picture a signal corresponding to the sound recording tape is provided and that by means of an electric circuit to detect the coincidence of both signals, the switching over to the next picture of the sound recording tape is carried out.

    • In a printing control device provided with a printing element having a plurality of characters thereon and operable to selectively present any desired character to a printing position, two-position control elements are connected to the printing element to control the amount of displacement required for one of the characters to be selected. Transmission elements are provided to cause the control elements to predetermine or prepare one of the two positions thereof, respectively. The control elements, caused to predetermine or prepare a particular position by the transmission elements, are driven toward the particular position by a drive means. At least one bias means is provided for biasing the transmission elements so as to predetermine or prepare a first position. The biasing force of the bias means is limited by a plurality of limit means to hold the transmission elements so as to predetermine or prepare a second position. The limit imparted to the bias means by the limit means is released selectively by electromagnetic solenoids to selectively bias the transmission elements so as to predetermine or prepare the first position. The transmission element so selectively biased is caused by at least one restore means to return to the position for predeterming or preparing the second position with the aid of the drive from the drive means and against the biasing force of the bias means.

    • A microfiche film projector device includes an illuminating lamp, a microfiche film carrier having two transparent members displaceable together and adapted to hold a microfiche film therebetween while scanned by a fixed optical system, projection means and a projection surface. The microfiche film carrier comprises a movable frame carrying the transparent members thereon, a base frame holding the movable frame slidably in scanning direction and displaceable in a direction different from the scanning direction, and camming portions engageable by one of the two transparent members so as to space them apart from each other. The projection means includes a projection lens assembly, and a resilient holding portion for urging the lens assembly against one of the two transparent members and holding it so that when the one transparent member is spaced from the other one, the end face of the lens assembly contacting the one transparent member is displaced while keeping a uniform contact with the latter. The projector device further includes a mask member disposed adjacent to the film carrier and movable to indicate any desired portion of the miniature images on the film to be projected.
