    摘要： A photographic camera has a rectilinear approximate operation circuit for calculating characteristic correction data for correcting errors in the operational characteristics of the camera. Predetermined theoretical characteristic data dependent on operational characteristics of the camera are stored. Measured data corresponding to predetermined measured values are stored as individually measured characteristic data in a nonvolatile EEPROM so that the stored measured data can be easily changed by rewriting the EEPROM. An object signal is generated depending on an object to be photographed. The rectilinear approximate operational circuit calculates characteristic correction data from the object signal, the theoretical characteristic data and the measured characteristic data, which is then used for correcting errors in the operation characteristics of the camera.

    摘要： Printing wires are able to be changed over from one to another by the movement of a printing head alone, thereby eliminating the need for a solenoid and simplifying the arrangement. The printing quality is improved by uniformly guiding the printing wires with the entire circumference of each guide hole, and further the amount of torsion of the printing wires caused by changeover of the printing wire arrangements is equalized, thereby stabilizing the printing characteristics and eliminating the difference in the printing characteristics between the parallel and staggered arrangements and also improving the durability. A first front guide is secured to a nose portion of a head frame. A front guide supporting frame, which supports a second front guide, is provided on the nose portion of the head frame so that the frame is movable in the direction of alignment of the printing wires. The printing wires are guided by the second front guide and the first front guide. The head frame is provided with a sliding member and a transmission-changeover means which causes the front guide supporting frame to be displaced in response to displacement of the sliding member. When the printing head is moved beyond the normal travel region, the sliding member abuts against a stationary member in the printer and is thereby displaced. The transmission-changeover means causes the front guide supporting frame to be displaced in response to the displacement of the sliding member, thereby moving the second front guide, and thus changing over the staggered and parallel arrangements from one to the other.
