Abstract
Abstract A side printing apparatus for providing latent images of characters, numerals, symbols and the like on a photographic film moving in continuous motion includes a film sensitivity responsive means for generating several kinds of pulse having different pulse lengths which are predetermined in accordance with sensitivity of film. The pulse operates to cause a light image forming device to be energized for a time defined corresponding to the pulse length thereof so as to provide a latent image of character, numeral, symbol or the like on a photographic film.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
A side printing apparatus for providing latent images of characters, numerals, symbols and the like on a photographic film moving in continuous motion by exposing it to light images produced by a light image forming device said apparatus comprising: means for giving an indication of the film type of a photographic film to be provided with latent images thereon; means for generating pulse signals having a pulse length in accordance with the film type indication from said means; and drive means for causing a light image forming device to be energized for a time defined corresponding to said pulse length so as to produce said latent images.
Claim 2
Dependent Claim
107 words
A side printing apparatus for providing latent images of characters, numerals, symbols and the like on a photographic film moving in continuous motion by exposing it to light images produced by a light image forming device said apparatus comprising: means for giving an indication of the film type of a photographic film to be provided with latent images thereon; means for generating pulse signals having a pulse length in accordance with the film type indication from said means; and drive means for causing a light image forming device to be energized for a time defined corresponding to said pulse length so as to produce said latent images.
Claim 3
Dependent Claim
110 words
A side printing apparatus as claimed in claim 1 wherein said pulse signal generating means comprising: an oscillator for producing a clock pulse; a gate for controlling the clock pulse from said oscillator to pass therethrough; a first counter for generating said pulse signals till the count of said clock pulse counted reaches a preset count which is preset by said film type indication; and a second counter for counting the number of said generation of said pulse signals so as to cause side gate to close when said counted number becomes equal to the number of column to a picture element matrix of character, numeral, symbol or the like.
Claim 4
Dependent Claim
34 words
A side printing apparatus as claimed in claim 1 wherein said light image forming arrangement comprises a character display device of the type having a plurality of light emitting diodes disposed in a matrix.
Claim 5
Dependent Claim
32 words
A side printing apparatus as defined in claim 3 further comprising a shift register for counting output signals from said first counter so as to drive said drive means consecutively every column.
Claim 6
Dependent Claim
87 words
A side printing apparatus as defined in claim 1 wherein said pulse signal generating means comprises means for generating a plurality of pulses with different pulse lengths, means for selecting one of said plurality of pulses in accordance with said film type, and counter means for counting said selected pulse so as to allow said selected pulse of which the number is equal to the number of column to a picture element matrix of character, numeral, symbol or the like to be directed to said drive means.
Claim 7
Dependent Claim
43 words
A side printing apparatus as defined in claim 5 wherein said means for generating a plurality of pulse comprises an oscillator for producing a clock pulse and at least a frequency dividing device for dividing said clock pulse from said clock pulse oscillator.
Claim 8
Dependent Claim
53 words
A side printing apparatus as defined in claim 6 wherein said selecting means comprises AND circuits of which the number is equal to the number of said pulses with different pulse lengths, said AND circuit calculating a logical sum of said selected pulse and a signal provided by said film type indication means.
Claim 9
Dependent Claim
34 words
A side printing apparatus as defined in claim 7 wherein said light image forming arrangement comprised a character display device of the type having a plurality of light emitting diodes disposed in a matrix.
Claim 10
Dependent Claim
33 words
A side printing apparatus as defined in claim 8 further comprising a shift counter for counting output from said selected pulse counting means so as to drive said drive means consecutively every column.
