Abstract

PURPOSE:To position and clamp a microfiche accurately, easily, and speedily at any time by arranging two upper and lower transparent plates so that the end surface ridge part of the opening side of one transparent plate and the opposite side is in contact with or close to the microfiche clamping side surface of the other transparent plate while a fine gap is left. CONSTITUTION:While the upper transparent pate 33 is in closing rotation, the rear end side part of the microfiche F is clamped between abutting parts of the upper and lower transparent plates 32 and 33 and forced by the end surface ridge part 32a of the lower transparent plate toward a reference mounting rule member 35b. Consequently, even when a shock or wind pressure is generated in the closing operation of the upper transparent plate 33, it does not move from a specific reference mounting position easily and clamped stably between the upper and lower transparent plates 32 and 33. While the upper and lower transparent plates 32 and 33 are closed, no opening turning force operates on the upper transparent plate 33 as long as sliders 36 and 36 slide in length section ranges of rear half parts 30b and 30b of side walls 30 and 30 according to the front-rear moving operation of the 2nd movable frame 39, so that the microfiche F is held.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention [Field of Industrial Application] The present invention relates to a microfiche carrier installed in a microfiche projection device such as a microfiche reader and a printer for the same reader.

[Conventional technology]

The microfiche carrier is used by the projection optical section in order to search and position the required target image frame part of the numerous microscopic image frames (frames) regularly projected and recorded in a matrix on the microfiche surface in the projection optical section. This is a microfiche holding/moving device that moves the microfiche in the plane direction (X-Y movement, matrix movement).

Various methods and structures have been proposed for this, but
A movable type microfiche clamping plate is common. This consists of two upper and lower transparent plates that hold the microfiche in a sandwich and hold it flat, and a transparent plate that supports the two upper and lower transparent plates holding the microfiche and moves it in the plane direction relative to the projection optical section. It has a plate moving mechanism.

FIG. 12 shows a longitudinal sectional side view of the microfiche holding transparent plate portion of the carrier.

32 is a lower transparent plate, and 33 is an upper transparent plate. The lower transparent plate 32 is held substantially horizontally by a movable frame member (not shown) as one component of the transparent plate moving mechanism. Upper transparent plate 3
3, both left and right ends of a support member 35 integrally attached to its rear side are supported by the frame member so as to be rotatable about a pin shaft 39, and the pin shaft is attached to the upper surface of the lower transparent plate 32. Centering on 39, it opens and rotates like a crocodile mouth as shown by the solid line, and closes in and rotates freely as shown by the two-dot chain line.

With the upper transparent plate 33 open and held, insert the microfiche F between the lower and upper transparent plates 32 and 33, and use the support member 35 of the upper transparent plate as a storage reference ruler for the tip of the microfiche. After the microfiche is placed at a predetermined surface position on the lower transparent plate 32 by abutting the leading end of the microfish against the microfiche and adjusting its position in the left and right direction.

The upper transparent plate 33 is closed and rotated. As a result, the microfiche F is sandwiched and held between the lower and upper transparent plates 32@33, resulting in a set state. The used microfiche F is removed by opening and rotating the upper transparent plate 33, and sliding the microfiche on the lower transparent plate 32 toward the front side with a finger on the lower transparent plate 32.

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

Retrieval of the target image frame portion of the microfiche F held between the upper and lower transparent plates 32 and 33 to the projection optical section may be performed by manual operation of the transparent plate moving mechanism, or by automatic movement control. In some cases, this is done manually.In the manual type, align the index on the transparent plate moving mechanism side with the coordinate position corresponding to the target image frame address on the index plate (each frame arrangement coordinate board) fixedly placed on the League Kasagi machine side. The transparent plate moving mechanism is manually operated, whereby the target image frame portion of the microfiche is located in a position corresponding to the projection optical section and searched for. In the automatic type, by specifying and inputting the address (or number) of the target image frame into the control circuit, the transparent plate moving mechanism is automatically driven and controlled according to the input address, and the target image frame part of the microfiche corresponds to the projection optical section. located and searched.

[Problem that the invention seeks to solve]

Regardless of whether the above-mentioned microfiche carrier is a manual search type or an automatic search type, in order to accurately search for the target image frame, the microfiche F must be placed against the lower transparent plate 32 in advance. It is important to accurately position and place the microfiche F at a predetermined reference placement position, and to press and hold the microfiche F in this position with the upper transparent plate 33 as it is.

If the microfiche F is set between the upper and lower transparent plates 32@33 at a position shifted from the predetermined storage reference position, 1
In the manual search type, the target image frame is not accurately searched due to mismatch with the index plate, and in the automatic search type, the automatic drive control of the transparent plate moving mechanism is performed based on the input address of the target image frame. Similarly, the target image frame cannot be accurately retrieved due to the mismatch with the amount.

Microfiche F is a thin and light sheet-like film, so even if it is accurately positioned and placed at the designated storage reference position of the lower transparent plate 32, when you remove your hand or finger, the surface of the lower transparent plate 32 will disappear. The lower transparent plate 32 and the microfiche F placed on it do not come into close contact with each other, and both 32- easily slide on the top and easily shift from the predetermined storage reference position.
A state in which an air layer exists between F and the lower surface of the microfiche is floating above the surface of the lower transparent plate 32, or a state in which the lower transparent plate 32 is tilted to a certain degree or more due to the projection device being installed in an inclined position, etc. When the microfiche F is placed in the
In addition, the impact when the upper transparent plate 33 is closed against the lower transparent plate 32 is caused by wind pressure as well.
The sliding movement easily causes misalignment. Therefore, in practice, it is quite difficult to accurately position the microfiche F between the upper and lower transparent plates 32 and 33 without causing it to deviate from the predetermined reference placement position, and to set it in the clamped state.
There were many cases where it was time consuming.

Therefore, for example, a plate spring member for inserting and holding down the microfish is provided on the lower transparent plate 32 side, and the plate spring presses the microfish against the lower transparent plate surface, thereby removing the microfish placed on the lower transparent plate 32. There have been proposed devices that prevent sliding movement from a predetermined reference mounting position. However, this method tends to cause damage to the microfiche due to insertion and removal between the presser plate spring and the lower transparent plate 32.

The present invention does not cause the above-mentioned problem of microfiche damage, and moreover, the microfiche F can always be precisely, easily and quickly positioned at a predetermined storage reference position between the upper and lower transparent plates 32 and 33, and the microfiche can be held and set. The purpose is to provide products that are devised so that the state can be improved.

Summary: Structure of the Invention [Means for Solving the Problems] The present invention is characterized in that a microfiche is held in a sandwich by confining the transparent plates between two upper and lower transparent plates that open and close like a crocodile mouth. In a microfiche carrier of the setting type, when the two transparent plates (upper and lower) are opened, the end face ridge of the opening side of one transparent plate and the side opposite to the microfiche of the other transparent plate. The gist of the microfiche carrier is that two transparent plates (upper and lower) are disposed so as to be in contact with the holding side surface or in close relationship with a slight gap between them.

[For production]

Specifically, in FIGS. 1(a) and 1(b), the two upper and lower transparent plates 32 and 33 are opened in the shape of an alligator mouth, and the side opposite to the opening side of the lower transparent plate 32 is shown in FIGS. An example of a relationship state in which the end face ridge portion 32a of the upper transparent plate 33 is in contact with or is close to the lower surface of the microfiche holding side surface with a slight gap is shown in FIG. Upper transparent plate 3
An example of a relationship state in which the end face ridge portion 33a of No. 3 is in contact with or close to the upper surface of the lower transparent plate 32 with a slight gap is shown.

In any of the above cases, the microfiche F to be set is inserted between the upper and lower transparent plates 32 and 33 in the opened state, and the tip side of the microfiche F is brought into contact with the upper and lower transparent plates 32-33. The storage standard ruler member 3 is passed through between parts or between small gaps against some resistance.
The fifth sentence is brought into contact with 35a and its horizontal position is adjusted. Then, even if the microfiche F that has been positioned with the inserted fist is subsequently removed, the tip side is sandwiched between the abutting parts of the upper and lower transparent plates 32 and 33 or between the small gap. , the insertion positioning state is stably maintained.

Therefore, (1) As with the conventional method described above, positional deviations due to natural sliding movement after the fingers are released, same-positional deviations due to tilting of the device, and same-positional deviations due to wind pressure and impact during the closing operation of the upper and lower transparent plates can be prevented. The microfiche F can always be reliably and easily held and set at the normal storage position between the two transparent plates 32 and 33 using a structurally simple means.

(2) Microfiche, 4F<Ii! It is possible to bring the abutting or proximate portions of the two transparent plates 32 and 33 to the very edge of the microfiche tip edge, and the presser part can be attached to the transparent plates 32 and 33. −
33 itself, the image on the microfiche can be used as effectively as possible.

That is, the transparent plates 32-33 can be made smaller by reducing the extra surface area as much as possible.

(3) The microfiche F inserted and held in the abutting part or the adjacent part of the transparent plates 32-33 is
In the closing rotation of 2.33, the transparent plate end face ridge portion 32a
Alternatively, the storage reference ruler member 33a receives a force in the direction of the storage standard ruler member 35 or 35a, and the insertion and
Misalignment of the positioned microfiche F from the reference position is further actively prevented.

(4) Insert the microfiche F into the abutting part or the adjacent part of the transparent plates 32 and 33.
Since this is a very small portion of the tip side of the microfiche, there is virtually no problem of damage to the microfiche surface.

and a crimping tube 18 which loosely fits and holds it. 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 1 is mounted on the upper surface of the upper transparent plate 33.
Due to the elasticity of the microfiche carrier 9, the upper transparent plate 33 is always pressed and kept in close contact 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.

The target image frame portion of the microfish F, which is set between the lower transparent plate 32 and the upper transparent plate 33 of the microfish carrier, is the illumination part between the illumination light output aperture 11 and the imaging lens assembly 12. (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 a copy button is pressed, the image frame is enlarged and projected onto a photoreceptor or the like of a copying mechanism or projected onto a reading element array, and an enlarged image copy is output.

The microfiche carrier is the upper plate 2 of the lower case 2.

It is fitted and engaged within the strip 28. The first movable frame 23 can be freely slid on the face plate 21 of the lower case 2 in the left-right direction (X-X) of the upper face plate using the corner edges 27 and grooves 28 as guides.

Reference numeral 29 denotes 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 the side walls 30, 30 are used as guides to slide the first movable frame 23 in the front-rear direction (Y-Y), which is perpendicular to the horizontal movement of the first movable frame. Be free.

The second movable frame 29 has a horizontal frame side 31 inside the frame, and is divided into two parts, a small window frame section on the front side and a large window frame section on the rear side, using the horizontal frame side 31 as a boundary. In this example, the size of each of the front and rear window frame sections (window frame opening area) is approximately % of the entire size of the second movable frame 29 for the former, and approximately % for the latter.

The second movable frame longitudinal direction guide side wall 30 of the first movable frame 23
-30 has a first half part 30a and a second half part 30b whose border is a little closer to the front end than the approximately mid-longitudinal position of the longitudinal part, and the top surface of the first half part 30a is higher than the top surface of the second half part 30b. The image part 30a
The boundary between -30b and slope 30c. Also, the side wall of the front half portion 30a has an inward eave-like ridge 30d on its inner upper part.
・It forms 30d. 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 F, 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. 7 to 9.

The lower transparent plate 32 is fitted into the rear window frame portion of the second movable frame 29, and support block pieces 50, which are integrally attached with adhesive or the like, are attached to the left and right sides near the tip of the second movable frame 29. The frame 29 is mounted and supported by pin shafts 51 on the left and right sides of the frame 29, and the lower transparent plate 32 can swing freely around the pin shafts 51. Reference numeral 52 indicates a recess into which the support block piece 50 is inserted, which is formed inside the left and right sides of the second movable frame 29, and 53 is a bottle shaft insertion hole formed in the same frame.

On the other hand, the lower surfaces of the left and right portions on the rear end side of the lower transparent plate 32 are received and supported by the upper surfaces of the tip portions of a pair of left and right forward protruding leaf springs 54 whose bases are fixed to the second movable frame 29. The rear end side of the lower transparent plate 32 is constantly biased to lift and rotate around the pin shaft 51 by a spring 54 (FIGS. 8 to 10).

The upper transparent plate 33 has a supporting member 35 integrally fixed along its length with an adhesive or the like on the end face and lower face on the rear end side, and the left and right ends of the supporting member 35 are made to protrude outward, respectively. The pair of plate-shaped sliders 36 are integrally attached with screws 37 (FIG. 8). The left and right ends of the support member 35 and the left and right sides of the frame 29 are connected by pin shafts 39 that are supported by small holes formed in the respective frames. Therefore, the upper transparent plate 33 connects the lower transparent plate 33 with the pin shaft 39 as the center.
It can be rotated freely to open and close.

The pair of left and right small plate-shaped sliders 36 protrude above the left and right side walls 30 - 30 of the first movable frame 23 from cutout steps 40 formed on the left and right sides of the frame 29, respectively. , second
When the movable frame 29 is slid in the front-rear direction on the first movable frame 23, the side wall 30 is moved along with the movement of the second movable frame 29.
・Sliding movement on the upper surface of the latter half 30b/30b in the front and back direction.

35b is a member (storage reference ruler member) formed inwardly at both left and right ends of the upper transparent plate support member 35 to receive and position the tip side of the microfiche F placed on the lower transparent plate 32. It is a protrusion. Reference numeral 55 denotes a plate spring rivet groove formed in the upper surface portion of the upper transparent plate support member 35 to which the plate spring 54 corresponds.

41, 41 (Fig. 4) are guides protruding from the upper left and right sides of the front side of the first movable frame 23, and 42 (Fig. 5) are the second movable frame 29 corresponding to the positions of the guides. 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 of the second movable frame 29. As well as being guided, by the engagement between the guide element 41 and the guide groove 42, the front and rear 43 are operating handles formed on the front side of the second movable frame 29, and 44 are the operation handles formed on the side of the second movable frame 29. An indicator 45 (second
・Figures 3 and 6) are index plates that can be freely attached and detached from a predetermined surface position of the upper surface plate 21 of the lower case 2.

Then, if you pinch the handle 43 with your fingers and operate it forward, backward, left and right,
The transparent plates 32 and 3 are moved by the front-rearward movement (Y-Y) of the second movable frame 29 relative to the first movable frame 23 and the left-right movement (X-X) of the first movable frame 23 relative 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.
-30 slope 13 at the boundary between the first half 30a and the second half 3ob
It reaches 0C and is further pulled out until it climbs up the slope portion 30c.

T--+-+Also, the upper transparent plate 33 opens and rotates in an alligator shape upwards around the pin shaft 39 as the R rides on the second side JOc. 5, FIG. 9(a)), the opening of the upper transparent plate 33 eliminates the weight of the upper transparent plate 33 on the lower transparent plate 32, so that the lower transparent plate 32 is attached to the pin shaft 51.
The rear end side is lifted and rotated by the force of the leaf spring 54,
As a result, a ridge 32a on the rear end side end surface of the lower transparent plate 32
is brought into contact with the lower surface of the upper transparent plate 33 near the rear end as shown in FIG. 9(a).

Therefore, the microfiche F is inserted onto the lower transparent plate 32 through the front openings of the lower transparent plate 32 and the upper transparent plate 33, which are opened like an alligator, and the tip side of the microfiche F is inserted into the upper and lower transparent plates 33. - Pass through between the abutting portions of 33 against some resistance to abut against the placement reference ruler member 35b behind it, and adjust the position in the left and right direction (FIG. 9(b)); Then, even if the inserted and positioned microfiche F is subsequently removed from the hand, its tip side is sandwiched between the abutting parts of the upper and lower transparent plates 32 and 33, so that the inserted and positioned state is stable. Retained.

After placing the microfiche F, the second movable frame 29 is moved backward. Then, the sliders 36, 36 move down from the slope portions 30c, 30c, and move toward the rear portions 30b, 4Ob of the side walls 30, 30. As the sliders 36-36 move downward from the slope portion 30clI30C, the upper transparent plate 33 closes and rotates about the pin shaft 39 with respect to the lower transparent plate 32.

Due to this closing rotation of the upper transparent plate 33, the weight of the upper transparent plate 33 is placed on the lower transparent plate 32, and the rear end side of the lower transparent plate 32 is centered around the pin shaft 51 against the upward force of the leaf spring 54. Finally, as shown in FIG. 9(C), the upper and lower transparent plates 32 and 33 are closed approximately horizontally with the microfiche F sandwiched between them. During the closing rotation of the upper transparent plate 33, the rear end side of the microfiche F is connected to the upper and lower transparent plates 32 and 33.
It is inserted between the abutting parts of the upper transparent plate 33, and by receiving a force in the direction of the storage reference ruler member 35b by the lower transparent plate end face ridge 32a, the shock and wind pressure accompanying the closing operation of the upper transparent plate 33 are applied. Even if this happens, it will not easily move out of the predetermined storage reference position, and will be stably held between the upper and lower transparent plates 32 and 33 in that position.

When the upper and lower transparent plates 32 and 33 are in the closed state, the slider 36-3
As long as 6 is slidingly moving in the length range of the rear half portions 30b-3ob of the side walls 30, 30 in accordance with the rear movement operation of the second movable frame 39, no opening rotational force is applied to the upper transparent plate 33. Retained.

Thereafter, in order to align the index 44 with the coordinate position corresponding to the target image frame address on the index plate 45, the handle 43 moves the $2 movable frame 29 in the front-back direction Y-Y, and the first
By moving the movable frame 23 in the left-right direction XX, the target image frame portion in the microfiche F held between the upper and lower transparent plates 32-33 is located in the projection optical section. In FIG. 6, the index 44 is the index plate 4.
FIG. 6 is a diagram showing a state in which an image frame portion on the microfiche F side corresponding to mark D5 is located in the projection optical section.

In the above embodiment, the lifting and rotating biasing about the pin shaft 51 on the rear end side of the lower transparent plate 32 is not limited to the leaf spring 54, but an elastic member such as a coil spring Φ rubber member can also be used. . In addition, by setting the position of the pin shaft 51, which is the rotation fulcrum of the lower transparent plate 32, closer to the rear end than the midpoint in the length direction of the left and right sides of the lower transparent plate, the lower transparent plate It is also possible to apply the above-mentioned rotational bias by forward downward rotational force due to its own weight around the fulcrum.

As shown in FIG. 1(C), the ridge 33a of the rear end surface of the upper transparent plate 33 is in contact with the upper surface of the lower transparent plate 32, or in a relational configuration in which it is brought close to the upper surface with a slight gap. Good too,
The effects during operation are similar to those of the above embodiments.

For example, while keeping the lower transparent plate 32 in a substantially horizontal state in conjunction with the opening operation of the upper transparent plate 33, the solid line position), the twill portion 32a on the rear end surface of the lower transparent plate 32 may be brought into contact with the surface of the upper transparent plate 33 or may be brought close to it with a slight gap therebetween.

Upper and lower transparent plates 32-33 of used microfiche F
To remove the second movable frame 29 from between, pull out the second movable frame 29 until the sliders 36 of the movable frame climb onto the slopes 30c of the side walls 30.
3 becomes the open state shown in FIG. 9(b). Therefore, as shown in FIG. 10, the lower transparent plate 32 on which the microfiche 2 F is placed is pushed down with a finger against the elasticity of the leaf spring 54 after centering the bottle shaft 51.
Slide the upper surface of the lower transparent plate 32 toward you with your finger and pull it out from between the upper and lower transparent plates 32 and 33. In this case, since the lower transparent plate 32 has an inclined surface position facing downward, the lower transparent plate 32 The microfiche F, which is moved by sliding the top surface of the plate 32 toward the front side with a finger, has its front side passing above the horizontal frame side 31 on that side, and is moved smoothly without hitting the horizontal frame side 31. It can be taken out and moved. 1st
In Figure 1, in order to make it easier to take out, the upper surface of the horizontal frame side 31 is made into a concave curved surface 31a or a downwardly sloped front surface, and using that surface as a guide, the upper surface of the lower transparent plate 32 is slid toward the front for taking out. This is an example in which the moved microfiche F is deflected diagonally upward.

C. Effects of the Invention As described above, according to the present invention, in a microfish carrier with a movable microfish holding plate, microfish can be easily and accurately placed at a predetermined storage reference position between the upper and lower transparent plates. It is possible to quickly position the microfiche and set it in the clamped state without damaging the microfiche, so that the target image frame can be accurately searched, and the handling of leagues and the like is improved.
