Two bar code sensors are disposed at opposite sides of a passage of a photographic film, each bar code sensor having first and second photosensor arrays. The first and second photosensor arrays are located at the passages of the clock track and the data track, respectively, along a line perpendicular to the transportation direction of the photographic film. The DX bar code data and frame number bar code data are discriminated automatically based on the bar code data configuration read out with the bar code sensor units. The setting condition of the photographic film is detected, also based on the bar code data configuration. In case of an abnormal state of the setting conditions, an alarm display is output. The bar code data is written in a memory when the data change, or synchronously with reading the clock track of the DX bar code. The number of a frame set at the film mask is calculated by measuring the feed amount of the read-out frame number bar code.

Apparatus for reading bar codes recorded on photographic film

Two bar code sensors are disposed at opposite sides of a passage of a photographic film, each bar code sensor having two photosensors disposed along a line perpendicular to the transportation direction of the photographic film. Each time a photographic film is fed by a predetermined distance, signals outputted from the two bar code sensor units are sampled and are compared with the signals obtained at the second preceding sampling timing to convert them into binary signals. Based on the data configuration of binary signals, i.e., based on the discrimination between the start code and end code, or the presence or absence of a clock track, automatic discrimination is performed between DX bar code data and frame number bar code data which then are decoded into a film type and frame number, respectively. The setting conditions of a photographic film also can be determined based on the bar code data configuration. An alarm is output if the setting conditions are not normal. The feed amount of a read-out frame number code is measured to calculate the number of a frame set at the print stage. Reading a frame number bar code may be performed synchronously with reading the DX bar code clock track.

Method and apparatus for reading bar codes on photographic film and

Disclosed is a collating device for collating the images on a photographic film with those printed on a printing paper from the photographic film while conveying the film and the printing paper. The collating device includes a reading device for reading a frame number for identifying the frame image on the film, and a printing device for printing the frame number which has been read by the reading device on the printing paper on which has been printed the image on the film which corresponds to that frame member. The frame numbers of the film are printed on the printing paper on which have been printed the images on the film. In consequence, the print images on the printing paper are easily made to correspond to the corresponding frame images on the film, and designation of the frames is facilitated.

Collating device

An original film is provided with main numbers and sub numbers which are alternately located at intervals equivalent to the length of one half-size frame image, as well as bar codes which represent the main numbers and the sub numbers. Since the frame images on the original film can be specified by reading with a reading means the main numbers and/or the sub numbers located at the sides of the frame images to be printed onto the printing paper, the main numbers and/or the sub numbers are provided on the printing paper so as to identify the frame images on the original film.

Photographic printing method, apparatus therefor, and a strip of

A photographic printing tape puncher for recording, on a paper tape, information on exposure correction for each of image frames formed on an original picture film before the film is used to perform printing. A frame number reading means reads bar codes which represent frame numbers and which are recorded on a part of the original picture film. The information thereby read is recorded on the paper tape along with items of information on exposure correction for the corresponding image frames. The items of exposure correction information and the frame numbers relating to the image frames are recorded on the paper tape constantly in correspondence with each other. It is therefore possible to easily obtain desired exposure correction information by searching a corresponding image frame number on the paper tape.
