In this open state, the microfiche F is slided and guided along a guide member 31 to make insertion (taking-out) smooth. When the second moving frame 29 is moved backward, the upper transparent plate 33 is turned around the axis pin 39 and closes on the lower transparent plate 32 to retain the microfiche F between transparent plates 32 and 33, and the attitude of the lower transparent plate 32 is converted to the horizontal attitude and this plate 33 is held.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microfiche carrier that is installed in a microfiche projection device such as a microfift printer.

[Technical background and purpose of the invention]

The microfiche carrier projects and records data regularly in a matrix on the microfiche surface.

A microfiche holding/moving device that moves the microfiche in the plane direction relative to the projection optical section in order to search for and position the required target image frame in the projection optical section among the numerous microscopic image frames (frames) that are displayed. be.

Various methods and structures have been proposed for this, but
The most common type is a micro fitting with a movable clamping plate. This consists of two transparent plates (top and bottom) that are sandwiched between the entire microfiche sandwich and held flat, and a transparent plate that holds the microfiche in its entirety and moves it in the plane direction relative to the projection optical section. It has a plate moving mechanism.

The lower transparent plate is supported approximately horizontally by a transparent plate moving mechanism, and the upper transparent plate opens and closes with respect to the lower transparent plate. It is difficult to place the fish, insert it, and take out the used microfiche.

There are systems in which the upper transparent plate is opened and closed manually, and there are systems in which the upper transparent plate is opened and closed automatically in conjunction with movement of the transparent plate to a predetermined position by a moving mechanism.

Retrieval of the target image frame part of the microfiche, which is set between upper and lower transparent plates, to the projection optical unit may be performed by manual operation of the transparent plate movement mechanism, or may be performed by automatic movement control. . The manual type moves the transparent plate moving mechanism Kaneko kJ so that the index on the transparent plate moving mechanism side is aligned with the coordinate position corresponding to the target image frame address of the index plate (each frame arrangement coordinate plate) fixedly arranged on the main body side such as a reader. This allows the target image frame portion of the microfiche to be located in a position corresponding to the projection optical section and searched for. In the automatic type, by inputting the address (or number) of the target image frame into all control circuits, the transparent plate moving mechanism is automatically driven and controlled according to the manual address, and the target image frame part of the microfiche is used as the projection light source. Search by corresponding location.

Regardless of whether the microfin carrier described above is a manual search type or an automatic search type, in order to accurately search for the target image frame, it is necessary to place the microfiche in advance against the lower transparent plate. It is important to accurately position and place the microfiche at the 8th reference position, and to press and hold the microfiche in that position with the upper transparent plate.

If the microfiche is set between the upper and lower transparent plates with a misalignment from the predetermined reference position, or if the manual search type is used, it may not be possible to accurately search for the target image frame due to misalignment with the index plate. Not done. In the case of the automatic search method as well, the target image frame cannot be accurately searched due to the mismatch between the input address of the target image frame and the automatic drive control amount of the transparent plate moving mechanism.

Microfiche is a thin and light sheet-like film, so even if it is accurately positioned and placed at a predetermined reference position on the lower transparent plate, it will move naturally on the lower transparent plate when you remove your hand or finger. It easily slips 1E11 and easily deviates from the predetermined placement reference position. The lower transparent plate and the microfiche placed on it may not be close to each other and there is an air layer between them17, and the lower surface of the microfiche may be floating above the surface of the lower transparent plate, or the projection device may When the lower transparent plate is tilted to a certain degree or the like because the microfiche is placed in a tilted position, the microfiche placed above is likely to slip and shift its position. Even when the upper transparent plate is closed against the lower transparent plate, the impact or wind pressure can easily cause the microfiche described above to slide and shift position.

Therefore, in practice, it is very difficult and often time consuming to accurately position the microfiche between the upper and lower transparent plates from the predetermined reference position without any deviation and set it in the clamped state. .

Therefore, for example, a plate spring member for inserting and holding down the tip edge of the microfiche is provided on the lower transparent plate side, and the plate spring presses the tip edge of the microfiche against the lower transparent plate surface, allowing the microfiche placed on the lower transparent plate to be placed on the lower transparent plate. A device has been proposed that completely prevents the fish from slipping and shifting from a predetermined reference position. However, in this case, the tip edge of the microfiche is likely to be damaged due to insertion and removal between the presser plate spring and the lower transparent plate.

The present invention does not cause the above-mentioned problem of microfiche damage, and moreover, the microfiche is always accurately, easily and quickly positioned at a predetermined quantity reference position between the upper and lower transparent plates, and the microfiche is set in the clamped state. The purpose is to provide the most innovative products that can be used.

Furthermore, the present invention involves the insertion of microfiche between transparent plates,
The purpose is to enable easy removal.

[Solution means of the present invention]

The present invention provides a microfish carrier with a movable microfish holding plate as described above, in which the lower transparent plate is placed in an inclined position when the upper transparent plate is open, and the microfish is in an inclined position when the upper transparent plate is closed. The guide member is configured to be held in a substantially horizontal position while changing its position, so that the position of the guide member that guides the microfiche can be completely changed when inserting and removing the microfiche.

According to the present invention, it is possible to position and place the microfiche on a predetermined placement reference position of the lower transparent plate, and to hold the microfiche in place with the upper transparent plate while maintaining the placed state accurately and quickly.

Further, there is no problem of damage to the tip edge of the microfiche, which occurs when the microfiche is held down by an insertion presser plate spring member.

In addition, microfiche can be inserted and removed smoothly.

〔Example〕

This example is a microfiche league equipped with a handmade microfiche carrier according to the present invention.
The figure is a perspective view of the entire fish league, and Figure 5 is a diagram of the projection optical system.

Inside the lower case 2 are a lighting system consisting of a light source lamp 6 with a reflective concave mirror 5 on its back, a condenser lens 7, a heat insulating filter 8, a reflective mirror 9, a diffuser lens 10 having a diffuser surface 10a'i, and other components, such as a heat exhaust fan, It has built-in electrical circuits, etc. Illumination light is emitted upward from an opening 11 formed approximately in the center of the top plate 21 of the lower case 2. A diffusion screen 16 is disposed at the front opening of the upper case 3, and three optical path changing reflection mirrors 13-14 and 15 are built into the case.

An imaging lens assembly 12 is disposed between the illumination light output aperture 11 and the reflection mirror 13, and is composed of a lens barrel 17 and a crimp tube 18 in which the lens barrel 17 is loosely fitted and held. The crimping tube 18 is supported by the tip of a leaf spring 19 whose rear end is fixed to a stationary member 20 on the upper case 3 side, and can freely swing up and down due to the elasticity of the leaf spring 19. A leaf spring 19 is mounted on the upper surface of the upper transparent plate 33.
Due to the elasticity of the microfiche carrier, the upper transparent plate 33 is always kept in a pressed and close state with an appropriate force, and the upper transparent plate 33 moves in the plane direction as the microfiche carrier is operated while maintaining contact with the lower surface of the crimp tube 18.

Thus, the target image frame portion of the microfish F sandwiched and set between the lower transparent plate 32 and the upper transparent plate 33 of the microfish carrier is illuminated between the illumination light output aperture 11 and the imaging lens assembly 12. Department (Projection optical department)
When the search position is located, the image contents of that image frame are enlarged and projected onto the front screen 16 of the upper case 3. In the case of a league printer, when the copy button is pressed, the image frame is enlarged and projected onto the photoreceptor of the copying mechanism, and an enlarged image copy is output.

The microfiche carrier is the upper plate 2 of the lower case 2.
], and 22 is its overall general code.

Reference numeral 23 designates a first movable frame as a constituent member of the microfiche carrier, and there are movable frames parallel to each other in the left and right direction along the length of the frame sides on the lower side of the front frame side and the rear frame side, respectively. ridges 24 and 25 are formed on the front side, and the front side ridge 24 is engaged with the corner edge 27 of the meeting part of the front plate 26 and the upper plate 21 of the lower case 2, and the rear side Projection 2
5 is a groove 28 formed on the upper surface plate 21 in the left-right direction of the upper surface plate.
It is fitted and engaged inside. The first movable frame 23 is guided by the corner edges 27 and the grooves 28 and moves toward the lower case 2.
The top plate 21 can be freely slid in the left and right directions (X-X).

2.9 is a second movable frame, which is fitted between side walls 30 provided on the upper surface of each frame side on the left and right sides of the first movable frame 23 in parallel with each other in the front-rear direction along the length of the frame side. It is supported on the first movable frame 23, and slides on the first movable frame 23 using the side walls 30, 30 as a guide in the front-back direction (¥-Y) that is perpendicular to the left-right movement of the first movable body. Free to operate.

The second movable frame longitudinal direction guide side wall 30 of the first movable frame 23
- 30 has a first half 30a and a second half 30b bordering at a position t' slightly closer to the front end than the approximately mid-longitudinal position thereof, and has a step such that the top surface of the first half 30a is higher than the top surface of the second half 30b. There is a picture part 30
The boundary between a and 30b is a sloped portion 30c. Further, the side wall of the front half portion 30a has an inward eave-like ridge 30 on its inner upper part.
d.30d is formed. These projecting edges 30d-30d serve to prevent the second movable frame 29 from moving upwardly (lifting off) from between the side walls 30, 30.

32 and 33 are two transparent plates (glass plate, resin plate, etc.) on the lower side and upper side that hold the microfiche Pi, which are arranged and held in the large window frame on the rear side of the second movable frame 29. . The arrangement structure of the transparent plates 32 and 33 will be explained with reference to FIGS. 1 to 3 and FIG. 6.

The lower transparent plate 32 is disposed at the rear window frame portion of the second movable frame 29 via a pair of push-up leaf springs 34 disposed on the left and right frame sides, respectively, with their bases fully fixed.

This lower transparent plate 32 has the following features: (1) As will be described later with respect to this plate 32, the upper transparent plate 3
3 is held in the open state and the weight of the upper transparent plate 330 is not lifted, the leaf spring 3 is pushed up as shown in the second figure.
4, the front side is lifted and rotated using the abutment between the back side of the lower transparent plate 32 and the step 29a on the frame 29 side that receives the back side as a fulcrum, and the front side is lifted and rotated from the frame to the rear. It is in a state of floating 75' on a downward slope.

(2) Conversely, the upper transparent plate 33 is closed and the lower transparent plate 32
When the full weight of the upper transparent plate 33 is applied to the upper transparent plate 33, the push-up plate spring 34 is pushed downward and falls into the frame portion to be received by the upper transparent plate 33 as shown in the third figure.
It is converted and held in a substantially horizontal position, including the horizontal position.

When the upper transparent plate 33 is opened, the plate spring 34 pushes up and holds the lower transparent plate 32 in a backward downward slope position of about 5° to 10°, and when the upper transparent plate 33 is closed, The lower transparent plate 32 is made to have elastic characteristics such that the lower transparent plate 32 is pushed down and deformed until the frame sK completely collapses and is received.

The upper transparent plate 33 is integrally fixed to the lower surface of its rear side along its length using an adhesive or the like.

A pair of small plate-like sliders 36 are fitted with screws 37 at the left and right lug portions of the rotating member 35, respectively, projecting outward.
(Fig. 6), it is installed in one piece. and rotating member 35
Both the left and right 'P4 parts of the frame 29 are connected to the left and right frame sides of the frame 29 by shaft pins 39 which are supported in small holes 38 formed in the respective frame sides. Therefore, the upper transparent plate 33 can freely rotate to open and close relative to the lower transparent plate 32 about the shaft pin 39.

The pair of left and right small plate-like sliders 36, 36 have notched step portions 40 formed on the left and right sides of the frame 29, respectively, and project above the left and right side walls 30, 30 of the first movable frame 23. , second
When the movable frame 29 slides back and forth on the first movable frame 23, 1! As the second movable frame 29 moves, the side wall 3
It slides in the front and back direction on the upper surface of the second half portions 30b and 30b of 0.30.

Reference numeral 31 denotes a microfiche guide member provided on the lower transparent plate 32, which has a substantially horizontal guide surface 31a located above the upper surface of the lower transparent plate 32 and an inclined guide surface 31b. The tip is fixed to the lower surface of the lower transparent plate 32.

Reference numerals 35a designate protrusions formed inwardly at both left and right ends of the rotating member 35 to receive and position the microfiche F placed on the lower transparent plate 32 on the back side.

4l-41 (Fig. 7) is a guide provided on the upper side of the front side of the first movable frame 23 with traps protruding from the left and right sides, and 42 (Fig. 8) is a second movable frame 29 corresponding to the position of the guide. Guide engagement guide grooves are formed along the longitudinal length of the frame sides at the lower surface positions of the left and right frame sides, and the second movable frame 29 is moved forward and backward by the left and right longitudinal side walls 3° on the first movable frame 23 side. Along with being guided,
The guide element 41 and the guide groove 42 are engaged with each other to be guided in the front and rear direction. .

43 is an operating handle formed on the front side of the second movable frame 29; 44 is an indicator provided at the longitudinal center of the horizontal frame side 31 of the second movable frame 29 so as to protrude into the small window frame; 45; is an index plate that can be freely attached and detached at a predetermined position on the upper surface plate 210 of the lower case 2.

Then, if you pinch the handle with your 43-karat gold fingers and operate it forward, backward, left and right,
The transparent plate 32Φ3 is caused by the back and forth movement (Y-Y) of the second movable frame 29 with respect to the first movable frame 23 and the left and right movement (X-X) of the first movable frame 23 with respect to the lower case top plate 21.
3 moves forward, backward, left and right in the plane direction with respect to the illumination section between the illumination light output aperture 11 and the imaging lens assembly 12 (X/Y movement).

When setting the microfiche F, pull out the second movable frame 29 forward so that the sliders 36 and 36 are aligned with the side wall 30.
・Slope portion 3 at the boundary between the first half 30a and the second half 30b of 30
0c and then pull it out until it climbs up the slope 30c.

Then, as the sliders 36 ride up on the slope portion 30c, the upper transparent plate 33 opens and rotates upward about the shaft pin 39 (FIG. F2, 8).

Further, by opening the upper transparent plate 33, the lower transparent plate 32 is converted and held in the backward downward inclined plane state by the push-up leaf spring 34 as explained in the above item (1).

Therefore, insert the microfiche Ft onto the lower transparent plate 32 through the front openings of the lower transparent plate 32 and the upper transparent plate 33 in the open state, and insert the microfiche F onto the lower transparent plate 32 and place the front side of the microfiche F on the rotating member 35 of the upper transparent plate 33. Formed positioning member 35a
By abutting the left side or the right side of the first Icro-Fish F against the circular surface of the left frame side or the right frame side of the second movable frame 29, it is positioned and placed at a predetermined placement reference position on the lower transparent plate 32. place Since the lower transparent plate 32 is inclined downward in the direction of the positioning member 35a, the mounted microfiche F is stably held without shifting from the predetermined reference position set at the beginning, that is, the upper transparent plate is opened. In this state, the lower transparent plate is converted to an inclined plane posture in which the microfiche is placed at the lower position relative to the lower transparent plate, so that the microfiche is placed on the lower transparent plate in the inclined plane posture. A sliding force always acts on the placed microfiche in the direction of the ttS placement reference position.

As a result, once the microfiche is positioned and placed at a predetermined placement reference position on the lower transparent plate with its side against the positioning member, its position and placement state is actively maintained by the above-mentioned sliding force. In fact, even when you remove your hand or finger from the microfiche, it does not easily shift even if the impact or wind pressure is applied during the closing process of the parent side transparent plate, and the initial positioning and mounting state is stably maintained. Ru. Even if the mounted microfish moves away from the positioning member when you remove your hand or finger from the microfish, or due to the impact or wind pressure caused by the closing rotation of the upper transparent plate, the microfish will not be affected by the above-mentioned sliding downward force. Immediately, the receiver hits the positioning member again and naturally returns to its original positioning and mounting state.

After placing the microfiche Fi, move the second movable frame 29 backward. Then, the slider 36φ36 moves down from the slope portions 30c, 30c and moves toward the rear portions 30b, 30b of the side walls 30, 30. As the sliders 36-36 move downward from the slope portions 30c and 300, the upper transparent plate 33 closes and rotates about the shaft pin 39 with respect to the lower transparent plate 32. During the closing process, the upper transparent plate 33 first collapses onto the lower transparent plate 32 which is in a downwardly inclined plane position, and is clamped onto the microfiche Fffi sandwich placed on the lower transparent plate 32 as shown in FIG. It became a state of
Due to the subsequent falling down, the upper transparent plate 33 is attached to the lower transparent plate 32.
When the zero weight is finally applied, the leaf spring 34 is pushed down and the lower transparent plate 32, including the upper transparent plate 33, falls into the frame and is received as shown in the first figure. It is maintained in a substantially horizontal orientation. In this way, the lower transparent plate 32 rotates to close the upper transparent plate 33, and the microfiche F is mounted on the lower transparent plate 32.
Until it is pressed into the sandwich, it is held in an inclined plane attitude, so even if an impact or wind pressure is generated due to the closing operation of the upper transparent plate 33, it will not easily move from the predetermined mounting reference position and will not move from that position. Top and bottom transparent plates 32/33f ¥
Be held stably by l11.

When the upper and lower transparent plates 32 and 33 are in the closed state shown in the first diagram, the sliders 36 and 36 are in the rear half portions 30b-30b of the side walls 30 and 30.
As long as the second movable frame 29 is slidingly moved in the entire length section range along with the back-and-forth movement operation, the upper transparent plate 33 is held without any rotational force acting on it.

Thereafter, the handle 43 is used to move the second TIIJik! so that the index 44 is aligned with the coordinate position corresponding to the target image frame address on the index plate 45. lI frame 29 in the front and rear direction Y
-Y, and by moving the first movable frame 23 in the left-right direction Find the location. FIG. 9 is a diagram showing a state in which the index 44 is operated so as to correspond to the coordinate D5 of the index plate 45, and the image frame portion on the microfiche F side corresponding to the coordinate D5 is located in the projection optical section. It is.

The guide member 31 guides the microfiche along the guide surfaces 31a and 31b when inserting and removing the microfiche between the transparent plates 32 and 33.

By sliding and guiding the microfiche along the guide member 31 when the transparent plates 32 and 33 are in an open state, the microfiche can be inserted and taken out smoothly. This prevents the microfiche from getting under the lower transparent plate 32 when inserting the microfiche, or before the second movable frame 29 provided to prevent this, as shown in FIGS. 15 and 16. Side protrusion 81
This prevents problems such as the microfiche being caught in the s29a and not being able to be taken out.

Various means have been considered for the configuration of means for changing the horizontal position of the lower transparent plate 32 when the upper transparent plate is open and when the upper transparent plate is closed. Let it go. 10 to 12 show another example in which a cam is used instead of the leaf spring 34 to perform the above changing operation.

In the figure, reference numeral 46 denotes a lower transparent plate climbing slope cam member disposed on the left and right frame sides of the first movable frame 23. By moving forward, the sliders 36, 36 reach the slope portions 30c, 30c of the side walls 30, 30, and the slope portions 30c*30cK
A little before climbing up, the tip side of the lower transparent plate 32 reaches the position of the slope cam member 46, and the subsequent second movable frame 2
9, the lower transparent plate 32 climbs up on the inclined cam member 46 and slopes backward and downward, and finally climbs up as shown in FIG. The V-slide-r36-36 also rides on the sloped portion 30c*30cK, and the upper transparent plate 33 is also fully opened and rotated.

Microfish 2F on the lower transparent plate 32? When the second movable frame 29 is placed and moved backward, the upper transparent plate 33 first closes and rotates during the retreating process, and the lower transparent plate 33 is still mounted on the slope cam member 46 and is tilted backward. 3
2 as shown in the twelfth figure, and the mounted microfiche F is pressed into the sandwich. Then, as the second movable frame 29 continues to move backward, the tip of the lower transparent plate 32 descends from above the slope cam member 46 and retreats, cutting the edge.
It is held on the movable frame 29 in a substantially horizontal position. During this time, the sliders 36-36 of the upper transparent plate 33 separate from the slope portions 30c and 300, and the edge of the upper transparent plate 33 is cut off, and the microfiche Ft is also placed on the lower transparent plate 32 and closed in a substantially horizontal position. Become.

Note that there is no interference with the slope cam member on the second movable frame 29 side. The oblique cam member receiver is formed into a groove type.

FIG. 13 shows an example in which a member 13a for receiving and positioning the entire front side of the microfiche F is provided in the form of a pair of protrusions 35a1 on the left and right parts of the upper surface of the lower transparent plate 32 near the back side. Reference numeral 47 designates an escape hole for the projection 35a' formed on the upper transparent plate 33 side.

FIG. 14 shows an example in which the microfiche guide member 31' is integrated with the leaf spring 34. A portion of the guide member 31' is constantly pressed against the lower surface of the lower transparent plate 32 by the force of the plate spring 34. The posture of the guide member 31' changes according to the change in the posture of the lower transparent plate 32.

Note that the present invention can also be applied to a fish carrier having an automatic transparent plate moving mechanism that performs automatic retrieval.
