Description

[Detailed explanation of the invention] This invention is based on the following:
The present invention relates to a comform slide mounting device used for attaching an original to a predetermined position on a frame.

In recent years, when converting various types of information into microfilm, it has become common practice to project and photograph the image output from a computer and the image of a comform slide in duplicate.

The above-mentioned comform slide requires that the original plate be correctly attached to a predetermined position on the frame in order to prevent misalignment with the image from the computer when double projection is performed. The attachment position of the original to the frame in this comform slide is determined by the distance from the outer edge of the frame to the center line attached to each side of the original.

Conventionally, the attachment of the original to the frame in ComFormSlide has been carried out using an ordinary length measuring device, as there is no dedicated equipment, using the following procedure.

1 Position the frame on a jig with register marks.

2 Attach the original plate to the frame using a slow-drying adhesive, and visually align the center line of the original plate with the register mark.

3 Measure the length from the outer edge of the frame to the center line of the original using a length measuring device such as a digital liner. If the dimensions are not within the specifications, manually shift the original while observing visually to determine the position. Make adjustments.

4. Repeat measurements as appropriate until the adhesive is completely cured, correct any deviations that may occur during that time, and complete the work by curing the adhesive.

However, conventional attachment using the above-mentioned general length measuring device takes about 10 hours for the adhesive to dry and harden, which not only tends to cause misalignment of the original during that time, but also relies on visual inspection. However, since there are many cases, there is a drawback that there is a large error in the placement position of the original plate. In particular, the recent small COMFORM slides have a large magnification during projection, so
Extremely high original plate attachment position accuracy is required, and improvements in attachment position accuracy are desired. In addition, in the conventional work of attaching the original to the frame, measurements had to be repeated many times to correct for deviations over time until the adhesive completely cured, making the work complicated and time-consuming. It also has the disadvantage that it is difficult and the production efficiency is extremely low.

The present invention solves the above-mentioned conventional drawbacks.
The original plate can be attached to the frame with high precision in a short time.
The purpose is to provide a mounting device that is easy to handle.

That is, the present invention makes it possible to freely adjust the position of the original on the frame by holding the original slightly floating on the frame held in a fixed position, and also allows the position of the original to be adjusted freely on the frame. By making it possible to measure the length from the outer edge to the center line of the original, and by lowering the original into contact with the frame without shifting the horizontal positional relationship between the frame and the original, The present invention provides a mounting device for a comform slide that allows an original to be attached to a frame using instant adhesive or the like after measurement in a short time.

Hereinafter, the present invention will be specifically explained with reference to the drawings.

1 to 3 show an embodiment of the present invention. In the figures, 1 is a stage, and on this stage 1, a base stage 2, an auxiliary slide stage 3, and a measuring slide stage 4 are mounted. They are set up sequentially.
The auxiliary slide stage 3 and the measurement slide stage 4 slide in the X direction and the Y direction, which are two directions perpendicular to each other on a horizontal plane. It is configured to be slidable. That is, when the X-direction measurement dial 5 is turned, the auxiliary slide stage 3
slides on the base stage 2 in the X direction with the measurement slide stage 4 superimposed on it, and when the Y direction measurement dial 6 is turned, the measurement slide stage 4 slides on the auxiliary slide stage 3 in the Y direction. It slides in the direction.

On the other hand, a pair of linear encoders 7a are provided between the base stage 2 and the auxiliary slide stage 3.
A linear encoder 7b and a linear scale 8b are provided between the auxiliary slide stage 3 and the measurement slide stage 4, and a linear encoder 7b and a linear scale 8b are provided between the auxiliary slide stage 3 and the measurement slide stage 4. It is now possible to measure the length of movement in the direction.

A correction turntable 11 is provided on a support stage 9 fixed on the measurement slide stage 4 and is rotated in the horizontal direction by turning a correction turn dial 10. This correction turntable 11 is for making each side of the frame 13 supported on the frame support stand 12 parallel to the sliding direction of the measuring slide stage 4, that is, the X direction or the Y direction. It can be omitted if it can always be accurately mounted on the frame support stand 12.

Approximately at the center of the correction turntable 11, an adjustment slide stage 14 is provided which has the same structure as the measurement slide stage 4 described above and is configured to be slidable in two horizontal and right-angled directions. That is, an auxiliary slide stage 17 is provided that slides in the Y direction on a base stage 15 provided on the correction turntable 11 by turning the Y direction adjustment vernier dial 16. An adjustment slide stage 14 is provided on the top to be slid in the X direction by turning an X direction adjustment vernier dial 18. Furthermore, an adjustment turntable 20 is provided on the adjustment slide stage 14 and is rotated horizontally by turning an adjustment turn dial 19. A set lever 2 is mounted on the adjustment turntable 20.
An original plate holding table 22 is located thereon which is raised and lowered by hydraulic pressure by raising and lowering the original plate holding table 22. A slit 23 is formed on the upper surface of the original holding table 22, and is connected to a pump (not shown) via a suction pipe 24, so that the original 25 can be held by suction. Therefore, the original holding table 22 slides in two horizontal and right-angled directions together with the slide of the adjustment slide stage 14, and the adjustment turntable 20
The set lever 21 rotates in the horizontal direction as the set lever 21 rotates, and slides in the vertical direction by the set lever 21.

On the other hand, the correction turntable 11 stands up from the edge, and a frame support stand 12 is provided directly below the microscope 26 . The frame support stand 12 is for supporting the frame 13 of the Comform Slide on its upper surface, and has an opening 27 formed therein corresponding to the inner part surrounded by the supported frame 13. An original holding stand 22 projects above the frame support stand 12 from below through.

In this way, since the original holding table 22 and the frame supporting table 12 are both provided on the measuring slide stage 4, there is no deviation in their positional relationship as the measuring slide stage 4 slides. They will be moved together without being generated. On the other hand, the movement and rotation of the original holding table 22 due to the sliding of the adjusting slide stage 14 and the rotation of the adjusting turntable 20, and the vertical sliding of the original holding table 22 by the set lever 21 are caused by the movement of the frame supporting table 12. This is done regardless of rotation. Therefore, frame 1
3 and the original 25, and the original 25 is in frame 1.
The positional relationship between the frame 13 and the original 25 can be adjusted by moving and rotating the original holding stand 22 in a state slightly raised from 3, and by sliding the measuring slide stage 4 while observing with the microscope 26. The encoders 7a and 7b can read the length from the outer edge of the frame 13 to the center line of the original 25 without shifting the above-mentioned positional relationship.

On the frame support stand 12, backing plates 28 and 28' are fixed in parallel to each sliding direction of the measurement slide stage 4 in two horizontal and right-angled directions. Also,
On the side facing the backing plates 28, 28', a pressing jig 29 is provided which presses the frame 13 diagonally against the backing plates 28, 28' with the frame 13 placed therebetween. In addition, 30 is a hydraulic pipe.

Next, how to use the above-mentioned device will be explained. First, the frame 13 is mounted on the frame support stand 12, and then the lever 21 is used to move the frame 13 onto the original holding stand 22.
The original plate 25 is held on the original plate holder 22 in a state slightly lifted from the frame 13.

Next, it is confirmed whether each side of the frame 13 is aligned with the sliding direction of the measuring slide stage 4. This is done by aligning the base line of the microscope 26 with one side of the frame and then moving the measurement slide stage 4.
Just slide it and check if there is a shift between the start and end points. If there is any deviation, the correction can be made by rotating the correction turntable 11. In particular, this misalignment of the frame 13 is largely controlled by the precision of the support mechanism for the frame 13 on the frame support stand 12 and the processing precision of the frame 13 itself, so if these are resolved, the correction turntable 11 can be omitted. . Further, the correction turntable 11 is formed into a donut shape,
Only the frame support base 12 may be rotated.

After positioning the frame 13 accurately in this way, align the base line of the microscope 26 with the outer edge of one side of the frame 13, and use that as the starting point to move the encoder 7.
While reading a or 7b, slide the measuring slide stage 4 by a predetermined reference dimension.

Next, the original holding table 22 is slid and rotated to align the center lines of the two sides of the opposing originals 25 with the base line of the microscope 26, thereby making them parallel to the reference dimension. Similarly, the center lines of the remaining two sides are determined to be parallel to the reference method. If the original plate 25 is twisted, this error may be distributed to four center lines so that the position of each center line falls within a predetermined tolerance range. In this case, it is convenient for the adjustment work to be able to read the slide length of the adjustment slide stage 14 and the rotation angle of the adjustment turntable 20. Furthermore, although the illustrated apparatus uses one microscope 26, two microscopes 26 are used, and these are horizontally arranged.
It is also preferable to mount it so that it can be rotated by 90 degrees so that the center lines of two opposing sides of the original plate 25 can be viewed at the same time.

After the adjustment is completed, slide the original holding stand 22 further upwards, apply adhesive to the frame 13, lower the original holding stand 22, and remove the frame 13.
The original plate 25 may be brought into contact with the original plate 25 for adhesion.In particular, an instant adhesive may be used for adhesion.

In the above explanation, an encoder is used to measure the slide length of the measurement slide stage, but the present invention is not limited to this. Any method may be used as long as it can be determined. In particular, the accuracy of the device of the present invention is greatly affected by the reading of the slide length of the measuring slide stage, so it is preferable to determine the length measuring means according to the required accuracy.

The advantages of the device according to the present invention are listed below.

1. Since positioning can always be performed by observation through a microscope, highly accurate positioning can be performed by fully utilizing the accuracy of the means for measuring the moving length of the measuring slide stage.

2 All movement of the original plate is done via equipment,
Since fine adjustments can be made without relying on human intuition, even beginners can perform work efficiently and with high precision.

3 By raising and lowering the original holding table, it is possible to bond in a short time using instant adhesive, and there is no need for additional measurements until the adhesive is completely cured.
Work can be completed in a short time.
