The first timing signal St1 is output when the predetermined film length stored in 0 is reached. Register 200
Stores the film length (full size or half size) sent from the main control unit 182.

Based on the input of the first timing signal St 1 from the film length detecting section 192, the rotation number counting section 194 generates a pulse of the electric signal Sa from the rotary encoder 134 attached to the rotating shaft 114 of the drive motor 112. Start counting the next first timing signal St
1 based on the input (count value D
c) is output to the winding diameter calculation unit 196 at the subsequent stage, and at the same time, the count value Dc is reset to zero. That is, for example, the counting of the pulses is started based on the input of the odd-numbered first timing signal St1, and the even-numbered first timing signal St1 is started.
The count value Dc is output based on the input of “1”, and is reset to “0” at the same time.

The rotary encoder 134 may be constituted by a code plate that generates a pulse train corresponding to the number of rotations, or one pulse is output each time the rotation shaft 114 of the drive motor 112 makes one rotation. May be configured.

The rotation speed suitable for the winding diameter obtained in the above, that is, the rotation speed at which the photographic film having the specified film length is to be sent out within a predetermined time is determined and output as the corrected rotation speed De.

The corrected rotation speed De output from the rotation speed correction section 198 is supplied to a motor control circuit 202 for feedback controlling the drive motor 112. The motor control circuit 202 compares the supplied corrected rotation speed De with the current rotation speed of the drive motor 112, and drives the motor so that the rotation speed of the drive motor 112 becomes the corrected rotation speed De within a predetermined time. A necessary drive current is supplied to the circuit 204.

As a result, the film roll 11 is rotated at a rotational speed corresponding to the winding diameter of the film roll 116A or 116B.
Rotate 6A or 116B to rotate long photo film 110
Can be continuously sent out, and the long photographic film 110 can be efficiently sent out to the subsequent transport system.

In the rotation control means 190, a register 200 stores a film length corresponding to the type of the current film, calculates a winding diameter based on the film length, and corrects the rotation according to the winding diameter. Since the number De is obtained, the photographic film strip 18 to be produced
Roll 116A at the optimal rotation speed according to the type of
Alternatively, the elongate photographic film 110 can be sent out from 116B.

As the rotation control means 190, in particular, the film length detection section 192 and the rotation number counting section 194, a configuration as shown in FIG.

That is, when the long photographic film 110 is cut into a predetermined length by the film cutter 148, the conveyance thereof is temporarily stopped. Even during the stop period, the long photographic film 110 is transferred from the long film roll 116A or 116B. Since the film 110 is continuously fed, the dancer roller 130 in the dancer roller section 118 moves downward by its own weight. By measuring the moving distance of the dancer roller 130 at that time, it is possible to detect the feeding length (film length) of the long photographic film 110. This movement distance can be detected by, for example, a voltage level of the electric signal Sb from the potentiometer 136 connected to the upper roller 124 of the dancer roller section 118, as shown in FIG.

Then, the film length detecting section 192 outputs the second timing signal St2 when the voltage level of the electric signal Sb from the potentiometer 136 reaches the voltage level corresponding to the predetermined length of the long photographic film 110. The configuration is as follows.

The rotation number counting section 194 receives a pulse of the electric signal Sa from the rotary encoder 134 based on the input of a signal indicating that the transport of the long photographic film 110 is stopped (a start signal Ss described later can be used). The counting of the number is started, and based on the input of the next second timing signal St2, the value (count value Dc) counted so far is output to the winding diameter calculation unit 196 at the subsequent stage, and the count value Dc is reset to 0 at the same time. It is constituted so that.

Even if the configuration shown in FIG. 10 is adopted, the film roll 116A or 116B can be continuously fed out at the number of rotations corresponding to the winding diameter of the film roll 116A or 116B, and the long photographic film 110 can be efficiently produced. It can be sent out to the subsequent transport system.

Next, the manufacturing apparatus 100 according to the present embodiment
The origin signal generation process, which is a feature of the first embodiment, will be described.

This origin signal generation processing is performed by origin signal generation means 210 (see FIG. 11) installed in the film supply unit 102. This origin signal generating means 210

On the other hand, as shown in FIG. 14A, the conveyor device 312 has two conveyors (an upstream conveyor 320 and a downstream conveyor 322). The length of the conveyors 320 and 322 is such that the length of the upstream conveyor 320 has a length of (length of the half-size photographic film strip 18 + α), and the length of the upstream conveyor 320 and the length of the downstream conveyor 322 are different. The total length is equal to (the length of the full-size photographic film strip 18 + α).

Will be present in the part. Therefore, when cutting is performed by stopping the conveyance by the conveyor 324, the conveyance of the photographic film strip 18 cut last time is also stopped, and the number of processes (throughput) per unit time is reduced accordingly, and the manufacturing efficiency is reduced. Cannot be improved.
