Title: Photographic camera
IPC: G03B15/00
Filed: 1960-07-18
Abstract: 939,345. Photographic cameras. ROBOT FOTO G.m.b.H. July 18, 1960 [July 18, 1959], No. 24907/60. Class 98 (1). In a photographic camera having separate electric driving motors for the shutter drive and the film feed respectively, the film feed driving motor is controlled by a contacting device actuated by the shaft of the shutter driving motor. As shown (Fig. 2), the shutter 6 of a photographic camera is drivingly connected to the shaft of a rotary-magnet motor 25 having stator windings 3, 3<SP>1</SP> and 5, 5<SP>1</SP> connected in a circuit as shown in Fig. 3. Similarly film feed mechanism 15 is drivingly connected through gearing 14 to the shaft of a second rotarymagnet motor 26 having stator windings 12, 12<SP>1</SP> and 13, 13<SP>1</SP>. Energization of the stator windings is controlled by contact discs 7-11 which are mounted on the two motor shafts as shown and discs 7, 8, 10 and 11 of which have segments constantly connected to a source of D.C. supply with polarity as indicated. In the rest position shown, windings 5, 5<SP>1</SP> are energized by way of disc 8 and a closed contact 20. On momentarily closing a switch 16, a relay 19 in circuit therewith is energized and contacts 20 and 17 which are coupled to the relay are respectively opened and closed. This results in rotation of the motor 25 owing to the respective de-energization and energization of the windings 5, 5<SP>1</SP> and 3, 31. Holding contacts 18 are provided for the relay 19. After a rotation of between 90 degrees and 100 degrees, relay 19 becomes de-energized, owing to the arrangement of conductive segments on the disc 7. As a result, windings 3, 3<SP>1</SP> also become de-energized whereas windings 5, 5<SP>1</SP> become re-energized, through disc 8 and closed contacts 20, with opposite polarity. The shaft of motor 25 therefore rotates through a further 90 degrees to close the shutter 6. After rotation of disc 9 through approximately 150 degrees, the contacts thereof short-circuit the contacts 21 whereby the motor 26 is actuated to rotate through 180 degrees (in a similar manner to that described above) for advancing the film by one image frame. If it is desired to take a time exposure switch means (not shown) are operated whereby contacts 18 are held open and a separate source of voltage (not shown) is connected across the two brushes engaging the disc 7. On closing the switch 16, the motor 25 will then rotate through 90 degrees and remain fettered in this (shutter open) position until the switch 16 is released.
