    摘要: A photographic printer for printing negative images on a negative film onto photographic paper. The printing direction can be changed over between "lateral" and "longitudinal" without changing the feed direction of the negative film. A reflecting mirror is inclined by 45.degree. with respect to the optical axis of the light emitted from a light source to the negative film and is supported to be rotatable about the optical axis. A driving unit is provided to rotate the reflecting mirror by 90.degree. about the optical axis between a reference position and a second position. Exposure stages are provided on the optical axes of the light beams reflected by the reflecting mirror when the mirror is in its reference position and second position, respectively. The photographic paper is guided through the exposure stages. According to the position of the mirror, negative images are printed on the paper at one of the two exposure stages. Thus, the printing position can be changed over between lateral and longitudinal by turning the mirror between its reference position and second position.

    摘要: A method of operating an air-supplied type coating booth in which conditioned air supplied from an air supply blower is enforced downwardly to the inside of a tunnel-shaped coating booth and the air in the coating booth is drawn together with paint mists and the likes down to the beneath of a booth floor by way of an air exhaust blower comprises the steps of detecting the flow velocity of air streams flowing into or out of inlet and the exit of the coating booth, applying primary and secondary averaging processings for signals for averaging variations caused by external disturbances fluctuating at relatively shorter and longer periods of time, judging the thus averaged direction and the flow velocity of the air streams at the inlet and the exit, variably controlling the flow rate of exhaust from the exhaust blower in accordance with the direction and the flow velocity. The exhaust blower means are divided into a plurality of blowers and the minute variations in the direction and the flow velocity are controlled excessively by the blowers situated at the inlet and the exit of the coating booth, while remaining exhaust blowers are operated at predetermined flow rate.

    摘要: A method of operating an air-supplied type coating booth adapted to enforce conditioned air by an air supply blower through a filter downwardly to the inside of a tunnel-shaped coating booth at a predetermined flow velocity and then drawn to discharge together with coating mists, etc. to the beneath of the floor comprises the step of detecting the flow velocity of conditioned air flowing through the filter to the inside of continuously, applying primary and secondary averaging processings for the detected signals containing variations fluctuating at relatively shorter and longer periods respectively, comparing the value obtained from the signals applied with the secondary averaging processing with a predetermined flow velocity value and variably controlling the flow rate of the air supplied from the air supply blower depending on the deviation and thereby maintaining the flow velocity of the conditioned air flowing to the inside of the coating booth always constant. Reduction of the flow velocity supplied to the inside of the air-supplied type coating booth due to the filter clogging can be compensated exactly with no effects of external disturbances.
