返し荷重で破壊する場合がある。 As is well known, in variable magnification copying machines,
Since the position of the projection lens is changed depending on the desired copying magnification, it is necessary to stop the lens stand on which the projection lens is mounted at a plurality of positions in the optical axis direction.
For this reason, the present applicant proposed a moving object stopping device that can be used for this purpose in U.S. Pat. No. 54-160388. That is, the moving object stopping device of this application includes a locking member that selectively stops the moving object depending on the presence or absence of a driving force of the moving object, and a locking member that detects when the moving object reaches just before the stop position. This device is equipped with a detection member that cuts off the driving force of a moving object.In order to keep the locking member at the required stop position, the spring plate is bent into an "L" shape and its position can be adjusted using a fixing screw. It is fixed at However, in such a structure for fixing the spring plate, an impulsive bending moment acts on the spring plate when the moving object (lens stand) is hit by the locking member or when the moving object moves again, so it is difficult to fix the spring plate. The parts may become loose easily, causing the moving object to stop at an inaccurate position, and the spring plate may break under repeated loads.

提案するものである。 The present invention solves the structural problems of the moving object stopping device as described above.The spring that keeps the locking member in a semi-fixed state is a spring plate whose base is press-fitted into the hole in the fixing part of the device. The present invention proposes that the spring plate be pressed against the locking member by a coil spring, and that the side surface of the base of the spring plate be immovably supported by a restraining plate.

An arcuate recess 9 centered on the protrusion 2 and two notches 11A and 11b into which a protrusion 10a of a spring plate 10 (described later) falls are formed. Since the detection member 8 has a protrusion sensing portion 8a protruding into the arcuate recess 9, when the protrusion 2 of the moving object 1 is sensed by the protrusion sensing portion 8a (i.e., the protrusion sensing portion 8a of the moving object 1 (immediately before the stop position), the micro switch 6 is operated by the detection member 8, and the drive motor of the moving object 1 is stopped.

2 is provided with a spring plate 10 whose base is press-fitted, the protrusion 10a of this spring plate 10 falls into the notches 11A, 11B of the locking member 7, and the base of this spring plate 10 is attached to the back surface of the mounting plate 4. It is secured by a restraining plate 14 fixed with screws 13. Therefore, even if a force in the rotational direction is applied to the locking member 7 from a moving object,
The press-fit relationship between the hole 12 and the spring plate 10 will not be incorrect. The mounting plate 4 has a folded piece 15 that is folded up facing the surface of the spring plate 10, and this folded piece 1
A coil spring 16 is interposed between the spring plate 5 and the spring plate 10 to press the spring plate 10 toward the locking member 7.

労することもない。 Since the illustrated embodiment has the above structure,
When the moving object reaches just before the stop position as it advances, the protrusion is sensed by the detection member, the micro switch is activated, and the driving of the moving object is stopped.
The moving object moves due to its inertia and stops when it hits the impact surface. When the moving object is restarted after completing the appropriate processing, the locking member is rotated to the position shown by the imaginary line in Fig. 1 against the force of the spring plate and coil spring, so that the moving object is not moved. The object will be released from the restraint of the locking member and will move freely. When a moving object is stopped or restarted, a complex force is applied from the locking member to the spring plate, but since the spring plate is reliably supported by the press-fit to the mounting plate and the restraining plate, the spring plate is The stopping position of the moving object will not become inaccurate due to the position changing, and
Since the semi-fixed state of the locking member is maintained by the coil spring, the spring plate will not fatigue prematurely due to repeated loads.
