An apparatus for reading images of a photographic film disposed on an image reading optical path, with a light source ( ) for emitting visible light and infrared light into the image reading optical path to irradiate the photographic film, and a zoom lens unit ( ) for the visible light and infrared light irradiating the photographic film. A visible light sensor and an infrared light sensor are disposed separately for detecting a visible image based on the visible light from the zoom lens unit, and for detecting an infrared image based on the infrared light from the zoom lens unit, respectively. A focal position varying transparent element (FT) is provided for shifting a focal position of the zoom lens unit along an optical axis. The transparent element is movable to and from a position between the zoom lens unit and infrared light sensor to correct variations in the focal position occurring with variations in magnification of the zoom lens unit.

Apparatus for reading images from photographic film

A vacuum fluorescent printer including a print head (,) having luminous blocks (,) each having a plurality of luminous elements arranged in a main scanning direction for irradiating a photosensitive material with light released from phosphorous objects to which electrons are applied based on a drive signal, thereby forming dots on the photosensitive material. A further luminous block (,) is provided which is spaced from the luminous blocks (,) in the sub-scanning direction and used for printing a particular color among the three colors (R, G, B). Each dot of the particular color is formed by light from a plurality of luminous blocks (,). A printer controller (,) is provided for generating a pulsed drive signal as the drive signal. The number of pulses in the drive signal is determined based on a density value of the image data, and the slower a moving speed is in the sub-scanning direction, to the larger pulse width the drive signal is set.
