Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fish carrier for positioning microfiche at a reading position of a projection device such as a reader or a printer.

Generally microfiche
Microscopic f-elements are regularly photographed in a matrix in a sheet-like microfilm called . Many minute images (hereinafter referred to as "
Various devices have been proposed for positioning microfiche at the reading position of a projection device in order to find and project a specific piece from among the pieces (referred to as "pieces"). Among them, the most popular method is to sandwich the microfiche between two glass plates, and while holding the drawing board, move the microfiche in parallel with the surface of the microfiche in a secondary direction or rotation. There is a fish carrier designed to make decisions.

FIG. 1 is a perspective view 1' of a conventional reader printer to which this type of fish carrier is applied. The main body of the reader printer consists of an upper machine box 1 and a lower machine box 2. Inside the upper machine box 1, well-known projection optical means, printing means, fault means, etc. are arranged, and inside the lower transmission box 2 there are illumination devices such as a light source lamp and a condensing lens.
Steps are arranged. Further, a fish carrier 16 as described above is attached to the lower machine box 2, and a handle 17 for movement operation is formed at the front i1s of the fish carrier 16. The operator grasps the handle 17 and moves the fish carrier 16 back and forth, left and right, or rotates it to set it at a desired position.
2nd (M+a+), the photographic configurations are the same, and tbl and tc+ in the same figure, the photographic configurations are not aligned. Place the microfiche in the configuration shown in Figure 1bl on the fish carrier 16 in this orientation. If projected across them, erect images will be obtained for A, C, L, and M, but horizontal images will be obtained for B and N.Therefore, the fish carrier 16 is rotatable 360 degrees. In cases like B and N, as shown in tel in the same figure, all positions are set so that an erect image can be obtained by rotating the fish carrier I6 by 90 degrees.However, when trying to rotate the fish carrier I6, the handle 17 is It is necessary to rotate the handle 17 by 90 degrees from the operating front position.Then, the handle 17 becomes sideways and becomes difficult to hold.The handle 17 moves away from the operator's hand and goes into the back of the device, making it difficult to operate. When projecting or copying a microfiche with a high reduction ratio (such as 48x), very delicate adjustments must be made to position the image (for example, when projecting using a 48x lens) (If the fish carrier moves by 1, the projected image moves by 48 mm.) In such a case, the poor operability of the handle 17 becomes a major drawback, making it impossible to accurately position the picture frame.

Therefore, a fish carrier as shown in Fig. 3 is being considered in which a handle 17' is provided at a location other than the front of the operation, but in this case, the fish carrier would be larger by the amount of the two handles 17 and 17'. It is necessary to increase the space in the portion of the projection device where the fish gear rear is placed, which has disadvantages such as an increase in the size of the projection device or a decrease in mechanical strength.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the present invention has been made in order to eliminate the above-mentioned drawbacks. The handle is removable so that it can be stored on the right side, left side, back side, etc. other than the front of the operation, improving operability when moving forward, backward, left, right, and rotating, and providing a compact fish carrier. The purpose is to

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 is a schematic diagram of a reader printer to which the inflow side of the fish carrier according to the present invention is applied. The main body of the reader printer consists of an upper machine box 1 and a lower machine box 2. In the lower machine box 2, well-known illumination means including a light source rung 3, a condensing lens 4, a reflecting mirror 5, a condensing lens 6, etc. are arranged. Inside the upper machine box 1, as a well-known means,
It has a projection optical means having a projection lens 7, a reflection mirror 8, etc., a reflection type screen 9 that receives reflected light from the reflection mirror 8, a copy paper supply cassette 10, a feed roller 11, a charger 12, a feed belt 13, etc. A printing means and a clear image means having a developer tank 14, a developing roller 15, etc. are provided. The screen 9 is normally arranged in an inclined manner within the upper machine box l, and is constructed by housing a light diffusion sheet such as paper in a rectangular base frame.

A d-fish carrier 1 in which a fish carrier 16 of the present invention is arranged between a condenser lens 6 and a projection lens 7
6 is removably attached to a carrier attachment plate 19, and the carrier attachment plate 19 is attached to a stand 20 on the upper part of the lower machine box 2 so as to be rotatable about the entire center of the original axis l. These rotating mechanisms allow the fish carrier 161i to rotate 360 degrees around the optical axis -4,
It is also movable in the front, back, left and right directions using a sliding # mechanism as will be described later with reference to FIG.

Here, the fish carrier 16 holds two glass plates Gl and G2 that sandwich the microfiche, and also has a handle 17 for positioning operation on the front side for the operator (on the left side in Figure 5g4). Operator is handle 1
7 to move the fish carrier 16 back and forth, left and right, and rotationally to displace the microfiche and place a desired image on the projection optical path.

An observation opening smaller than the screen 9 is formed in the front of the upper machine box 1, and a filter 18 is disposed in this opening. The operator reads the projected peaks by looking at the screen.

The filter 18 corrects the color temperature, and allows the viewer to pass through the filter 18 in the opening to view the reflective screen 9.
This optimizes the contrast of the image on the screen when reading the image above. As this filter, for example "Varad" (Marks Po1ariz
ed Corp's registered trademark a) is used. The screen 9 is connected to a moving mechanism (not shown), and during printing, the screen 9 is moved out of the projection optical path by the operation of the moving mechanism from the reading position shown by the solid line 9 in FIG. 3 to the opening position shown by the chain line 9'.

Next, regarding one embodiment of the fish carrier of the present invention,
This will be explained with reference to FIG. fish carrier 16
The device is generally composed of a rectangular substrate 16a, a rectangular plate-shaped first movable member 16b, and a plate-shaped second movable member 16c therein. The substrate 16a is attached to the carrier mounting plate 19 as shown in FIG.
° Can be rotated. One end of the first movable part 116b is attached to a guide shaft 16d formed on one end of the substrate 16a.
It is attached so as to be slidable in the X direction in the figure, and the other end is bent downward in a curved shape to engage with the other end of the substrate 16a so as to be slidable in the X direction. Therefore, the first movable member 161)
can be moved parallel to the substrate 16a in the X direction.

The second movable member 16c is detachable]11! The hand 17 and the two crow plates Gl and G2 that hold the fish (
(shown in FIG. 3).

The second movable member 16c is placed on the first movable member 161) so as to be slidable in the Y direction in the figure, and further supports the handle 17 and holds the glass plates Gl and G2.

Since the fish carrier 16 is constructed as described above, the microfiche is sandwiched between the two glass plates Gl and G2, and the microfiche is moved by holding the handle 17 back and forth, left and right, or by rotating it. You can position the desired image within. In normal use, the handle 17 is located on the front side of the main body of the apparatus (operation front 11+1), and the operator holds the handle 17 to align the position in the front-rear and left-right directions. Also, adjust the orientation of the f-elephant (for example, 74
When the fish carrier 16 is rotated 90 degrees counterclockwise from the above position in order to change the position from the position shown in Figure 2 (tbl) to the position shown in Figure 6 (tel), the handle 17 is moved from the position of the device as shown in Figure 6 (a). It will be difficult to remove the handle 17 because it will fit in the center of the
By attaching it to the front side as shown in FIG. 1b1, the operator can easily perform positioning 6 in the front, rear, left and right directions by holding the handle 17. Furthermore, since there is no need to provide a space between the walls for the handle in the portion of the projector main body where the fish carrier is placed, the projector main body does not become large and its mechanical strength does not become weak.

Figure 71111, +b1 shows the attachment and detachment structure of the handle 17.

FIG. 71a1 is a sectional view when the handle is attached, 21 is the bottle implanted in the second movable member 16c, 22 is the handle 17
With holes drilled at the same pitch spacing as the bottle 21,
It has a shape that fits with the

23 is a rubber magnet fixed to the back surface of the handle 17. The handle 17 is positioned by the bottle 21 and fixed to the magnetic part of the second movable member 16c by a rubber magnet 23. FIG. 7ib1 is a perspective view when the handle 17 is removed from the second movable member 16C. As shown in FIG. 5, the pair of bottles 21 are installed in the front and left and right sides of the carrier 16, respectively.

In the above embodiment, the handles can be attached and detached from the front side and the left and right sides of the fish carrier, but if the handles can be attached and detached from the back side of the fish carrier or from the corners, etc., the operability will be improved.
You can easily move in any direction.

Further, in the embodiment, a hole is provided in the handle as a mechanism for attaching and detaching the handle, and a bottle is installed in the carrier body, but the mechanism may be provided in the opposite manner.

Furthermore, various attachment/detachment mechanisms can be employed as long as they are easy to attach and detach and are securely fixed to the fish carrier main body during operation of the fish carrier.

As explained above, the present invention makes it possible to attach and detach handles for moving operations not only on the front side of the fish carrier but also on the right side, left side, back side, etc., so that the fish carrier can be moved forward, backward, left, right, or rotated. When searching for micro-platoons in the fish, the handle is always in front (on the operator's side) regardless of the imaging mode of the micro-image, so the handle can be easily held and the position can be easily traced. It has a very excellent effect of allowing adjustment and therefore improving operability.
