摘要： PROBLEM TO BE SOLVED: To realize a recording device, the printing accuracy of which is high and no poor detection due to wear and tear of which is present, by a constitution wherein a detecting part is supported movably to the direction normal to a linear scale and, at the same time, a guide member for controlling the relative position between the linear scale and the detecting part is equipped so as to correct the position of the detecting part with guide parts. SOLUTION: An optical linear scale 6 is mounted parallel to a guide shaft 1. An optical linear encoder consist of one light emitting part and the other light receiving part arranging facing each other across a groove provided at the middle parts of the encoder. In the groove part, the optical linear scale 6 is arranged under the condition that the groove part is supported movably by a retaining part 2a provided at the fore part of a carrier 2 normal to the optical linear scale 6 or to the direction A and further the groove is pressed against the retaining part 2a with a spring so as to develop no jolting between the groove and the retaining part. Further, two guide members 7 control and correct the position of the optical linear encoder 5 to the optical linear scale 6 and have guide parts 7a expanded at their respective one end.

摘要： PURPOSE:To provide the process for production of the optical element which is devised to avert the subsequent trouble based on the sticking of a molding to an upper mold member at the time of parting from the mold so as to allow the execution of continuous molding or molding at a high speed while maintaining good accuracy of the optical element. CONSTITUTION:This process for production of the optical element consists in producing the molding having a required optical function surface by housing a glass blank material for molding between the upper and lower mold members of the forming mold and press forming the material in the state of heating the material to a desired temp., then cooling the molding and parting the molding from the mold. The above-mentioned molding taking out stage includes a stage for detecting the position of the molding existing between the mold members by a sensor 7 in the state of opening the upper and lower mold members to a prescribed quantity, a stage for fully opening the mold members in accordance with the result of the position detection and a stage for taking out the molding.

摘要： PURPOSE:To improve conversion accuracy and to improve explosion proof property, environment resistance and the like, by coupling a controller part, which converts an input signal into a light signal, and a converter part, which feeds back an operating amount after it is converted into light, by a piece of optical fiber. CONSTITUTION:A controller part 2, which has a control and operation part 30, a light emitting part 40 and a light receiving part 50, is coupled with a converter part 3 by a piece of optical fiber 4. The converter part 3 is composed of a light to air pressure converter part 60 and an air pressure to light converter part 70. At an opening part of one end of a hollow optical fiber 61 in the converter part 60, a flapper 64 is provided. A hollow part is made to be an air path of supplied air. The inside of the wall is made to be the light path of a light signal. The change in back pressure of the supplied air due to the deformation of the flapper is taken out as the output air pressure. The light signal from the light emitting part 40 is converted into the output air pressure by the converter part 60. The pressure is used as an operating force. The operating amount is converted into light by the converter part 70. After the conversion, the amount is fed back to the light receiving part 50. The difference between a signal S2, which is proportional to the output air pressure from the converter part 3 and received by the light receiving part 50, and an input signal S1 is detected. The control operation part 30 is performed. Thus the feed-back system is constituted.
