Description

technical field [0001] The invention relates to the field of research technology, in particular to a slide show delivery device. Background technique [0002] Slide projectors were fairly common in the 1950s and 1960s, mainly for entertainment purposes, where family and friends would gather to view slideshows. Today, because of the popularity of low-cost paper publications, digital cameras, DVD media, liquid crystal displays, and digital projectors, slide projectors have been replaced, but some research fields often still use them, and the slides can be adjusted according to the focal length. To zoom in or zoom out, which is convenient for research, but the traditional way of adjusting the focus is through manual adjustment, and switching slides is also through manual adjustment, which is not conducive to operation. Contents of the invention [0003] The object of the present invention is to provide a slide show delivery device for overcoming the above-mentioned defects i...
