摘要： PURPOSE:To efficiently transfer the power from the 1st gear to the 2nd gear rotated with the power at the drive source side and to secure the discharge operation when the cassette is discharged by composing to install the coil spring coiled for the cylinder part of the 2nd gear and coupling the end to the 1st gear. CONSTITUTION:When a gear 64 is rotated in the clockwise direction by the power at the drive source side when a cassette 2 is discharged, a flange 60 and a coil spring 62 are rotated in one body in the clockwise direction, the slip torque is generated with the friction force located between a coil spring 62 and a cylinder part 65, a cylinder part 65 is rotated in the clockwise direction in one body with a gear 59 and a rack 29 is sent in the arrow B direction. Since a coil spring 62 is composed to rotate for a cylinder part 65, the transfer efficiency of the torque is larger, and consequently the slip torque increases and a gear 59 can be more securely rotated.

摘要： PURPOSE:To make suitably the timing of movement of members and to shorten the working time by moving a pressing member and a stabilizing member to the working positions to a center core of a recording carrier in accordance with the movement of a sliding member. CONSTITUTION:When a cassette 2 is inserted into a holder 9, a cam surface 25a of the sliding member 11 is moved in the left direction, so that a pin 24 is pushed up and a center core pressing member 23 is rotated in the D direction to push the center core 3 into a spindle 41 and position the center core 3 on a prescribed position precisely. Simultaneously, a pin 33 is descended by the movement of a cam groove of the sliding member 11 and an air layer between the stabilizing member 31 and the recording carrier 1 is formed in prescribed thickness. Thus, the pressing member 23 and the stabilizing member 31 are moved to their working positions by a single moving operation of the sliding member 11 by providing a proper timing and the whole working time can be shortened.

摘要： PURPOSE:To feed a recording or reproducing transducer accurately and to reduce the titled device at its size and cost by forming positioning means inside a transmission mechanism advancing the recording or reproducing transducer by a driving source. CONSTITUTION:The positioning means 19-22 are formed inside the transmission mechanism advancing the recording or reproducing transducer. A pin 19 is energized by a spring 21 and can be moved inside a hole 20 in the B direction in the figure. Since conical grooves 22 are formed on a cam 7 in each rotation angle corresponding to each track of a magnetic sheet 15, the pin 19 is engaged with the conical groove 22 in every track, so that the transducer device 10 is precisely positioned. When the transducer device 10 is to moved from the position to another position, the pin 19 is released from the conical groove 22 and inserted into the hole 21, so that the turning of the cam 7 is not interrupted.

摘要： PROBLEM TO BE SOLVED: To easily and precisely measure the form of a non-coaxial lens having a plurality of reflecting surfaces integrally formed thereon by providing a form measuring reference part in an optical element holding means, and measuring this form measuring reference part. SOLUTION: An optical element consists of a transparent body having a refracting surface on which a luminous flux incidents, a plurality of reflecting surfaces having curvature, and a refracting surface for emitting the luminous flux reflected by the reflecting surfaces, which are integrally formed thereon. An optical element holding means for holding this optical element has a form measuring reference part, and the absolute coordinate system of the optical element is regulated by measuring the form measuring reference part to measure the refracting surface and the reflecting surface. Namely, a holding jig 16 (holding means) has reference planes (form measuring reference parts) 16(a), 16(b), 16(c), 16(d), 16(e) corresponding to reference planes 7(a), 7(c), 7(d), 8(a), 8(c) in the form measurement of the optical element. The origin of the absolute coordinate system can be set by measuring these forms.

摘要： PROBLEM TO BE SOLVED: To stabilize the carrying performance of a recording sheet while improving the quality of a recorded image and to enhance the assembling performance of members and the processing performance of a recording sheet carried incorrectly by supporting the bearing parts of respective carrying rollers on the same base. SOLUTION: A discharge roller 20 and a discharge driven roller 21 pressed in the direction of the roller 20 are disposed on the carrying direction side with respect to a platen 19 secured to a base 25. The discharge roller 20 and the discharge driven roller 21 are supported rotatably, at the opposite ends in the axial direction thereof, by bearing parts 33, 34 secured to the base 25. Since the bearing parts 33, 34 for respective rollers 20, 21 are supported on a same base 25, the height of the joint between a subscanning roller 13 and a subscanning driven roller 14, the upper surface of the platen 19, and the joint between the discharging roller 20 and the discharging driven roller 21 can be determined accurately along with the parallelism between the joint on the subscanning roller 13 side and the joint on the discharging roller 20 side.

摘要： PROBLEM TO BE SOLVED: To prevent the reduction of optical performance due to the fitting state of an optical member by fixing one end of the optical member on a supporting member. SOLUTION: One end part 1h of the 1st optical member consisting of plastic or glass integrally forming two refractive faces and four reflecting faces is fixed on the fitting part 16 of a base 9 by screws 17. A reason for fixing the member 1 on its one end part 1h is to absorb expansion/reduction due to a temperature change especially when its material is plastic. In the case of 2nd and 3rd optical members 2, 3 also, one end of each member is fixed based on the similar reason so that the member can be expanded/reduced in its longitudinal direction. The clamping of one end part by screws is effective also for removing the adverse effect of stress due to scew clamping upon a part requiring optical performance.

摘要： PURPOSE: To provide the picture input device which enables an operator to easily recognize the document setting position even in the case that the optical axis position is deviated from a normal image pickup position by switching to the close-up position, replacement of a camera part, or the like. CONSTITUTION: A picture input device 1 is so constituted that a first camera part 2 can be replaced. Leg parts 7 and 8 are provided with light emitting elements 34 and 37 which emit the red light and light emitting elements 35 and 36 which emit the green light so that optical axis positions 15 and 16 of the first camera part 2 can be recognized more distinctly. Since green light emitting elements 35 and 36 are lit by power-on in the case of the first camera part 2, the optical axis position 15 of the first camera part 2 is recognized. For example, when the center part of a document 6 is aligned to this position, the document 6 is projected on the whole of the screen of a monitor 18. At the time of zooming up a required part, this part is brought to the optical axis position 15. When a second camera part is used, red light emitting elements 34 and 37 are lit, and the optical axis position 16 of the second camera part is recognized.
