Abstract

PURPOSE:To position accurately and quickly a microfiche to a reference placing position without damaging the microfiche, by maintaining the lower transparent plate of a microfiche carrier in an inclined position under a condition where the upper transparent plate is opened and in a horizontal position when the upper transparent plate is closed. CONSTITUTION:When a movable frame 29 which is movable in the forward and backward directions of a lower case is pulled forward and an upper transparent plate 33 is opened by rotating the plate 33 around a pin 39, a lower transparent plate 32 is changed to and maintained in an inclined position by means of the forcing force of a spring 34 while its inner edge is brought into contact with a stepped section 29a. When a microfiche F is inserted into this device under this condition and the upper plate 33 is closed while the microfiche is stable held with its inner edge being brought into contact with the positioning member 35a of the transparent plate 33, the plates 32 and 33 are changed to their horizontal positions by the weight of the plate 33 and the frame 29 is moved. Thus an aimed frame section of the microfiche is positioned to a projecting optical system. Therefore, the microfiche can be positioned to a reference placing position accurately and quickly without damages.

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 or a league printer.

[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 φ moving device that moves the microfiche in the plane direction.

Various methods and structures have been proposed for this, but
A movable type microfiche clamping plate is common. This consists of two transparent plates (top and bottom) that sandwich the microfiche and hold it flat, and two transparent plates (top and bottom) that hold the microfiche between them. It has a transparent plate moving mechanism for moving the transparent plate.

The lower transparent plate is supported approximately horizontally by a transparent plate moving mechanism, and the - side transparent plate opens and closes with respect to the lower transparent plate, and by opening and closing, it moves to a predetermined mounting reference position on the lower transparent plate. Microfiche is placed, inserted, and used microfiche is taken out. - There are systems in which the side transparent plate is opened and closed manually, and there are systems in which the opening and closing of the side transparent plate is performed automatically in conjunction with the movement of the transparent plate to a predetermined position by a moving mechanism.

Searching for the target image frame part of the microfiche, which is set between upper and lower transparent plates, into the projection optical section is done by manual operation of the transparent plate moving mechanism, or by automatic movement control. . In the manual type, the transparent plate moving mechanism is manually operated 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 array coordinate board) fixedly placed on the league Kasagi machine side. As a result, the target image frame portion of the microfiche is located corresponding to the projection optical section and searched. 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]

-1- Regardless of whether the microfiche carrier 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 against the lower transparent plate in advance. It is important to accurately position and place the microfiche at a predetermined placement reference position, and to press and hold the positioned microfiche with the upper transparent plate.

If the microfiche is set between the upper and lower transparent plates at a position shifted from the predetermined placement reference position, in the case of a manual search method, the target image frame will not be accurately searched due to the misalignment with the index plate. . In the case of the automatic retrieval method, the input address of the target image frame does not correspond to the automatic drive control amount of the transparent plate moving mechanism, so the target image frame cannot be accurately retrieved.

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 slides and moves, and is easily displaced from a predetermined reference mounting position. The lower transparent plate and the microfiche placed on one of them may not be in close contact with each other, and an air layer may exist between them, causing the lower surface of the microfiche to float above the surface of the lower transparent plate, or the projection device may be tilted. When the lower transparent plate is tilted to a certain degree due to being left in a fixed position, etc., the above-mentioned microfiche is likely to slip and shift position, and the upper transparent plate is closed with respect to the lower transparent plate. The microfiche device can easily slip and become misaligned due to shock or wind pressure. Therefore, in practice, it is quite difficult and often time-consuming to accurately position the microfiche between the upper and lower transparent plates without causing the microfiche to deviate from a predetermined reference placement position, and to set the microfiche in a 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 held down. A system has been proposed that prevents the fish from slipping and shifting from a predetermined storage 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 can be
Always accurately and easily place it at the specified mounting reference position between the lower transparent plates.
To provide a device devised so that it can be quickly positioned and put into a clamped set state.

Summary: Structure of the Invention [Means for Solving Problems] The present invention provides a microfiche carrier with a movable microfiche holding plate as described above, in which the lower transparent plate is moved when the upper transparent plate is in the open state. The structure is such that the microfish is held in an inclined plane attitude with the mounting reference position side facing the lower transparent plate, and - when the upper transparent plate is in the closed state, in a substantially horizontal plane attitude. .

[For production]

That is, when the upper transparent plate is in the open state, the lower transparent plate is converted and maintained in an inclined plane posture in which the microfiche mounting reference position side with respect to the lower transparent plate is at the lower side.
The lower transparent plate with the tilted surface posture! -, the microfish placed on the position is constantly subjected to a downward sliding force in the direction of the 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 abutting against the positioning member, the positioning and placement state is positively affected by the downward sliding force described in -. In fact -1- Even when you remove your hand or finger from the microfiche, or even if there is a shock or wind pressure during the closing process of the upper transparent plate, it will not easily shift and the initial position and storage state will remain stable. is maintained. 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.

Therefore, 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.

〔Example〕

This example is a microfish league equipped with a manual microfish carrier according to the present invention.
The figure is a perspective view of the entire fish league, and Figure 2 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 in front, a condenser lens 7, a heat insulating filter 8, a reflective mirror 9, a diffuser lens IO having a diffuser surface 10a, etc., a heat exhaust fan, and electricity. It has built-in circuits, etc. Illumination light is emitted upward from an opening ll 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 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.

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 ll 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 a copy button is pressed, the image frame is enlarged and projected onto a photoreceptor or the like of a copying mechanism, 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 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 upper plate 21 can be freely slid in the left-right direction (X-X).

Reference numeral 29 denotes a second movable frame, which is fitted between side walls 30 and 30 provided on the upper surface of each frame side on the left and right sides of the first movable frame 23 in parallel in the front-rear direction along the length of the frame side. 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-rear direction (y=y) that is perpendicular to the left-right movement of the first movable frame. Free to operate.

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 divided window frame portions (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 30a and a second half 30b whose border is a position slightly closer to the front end than the approximately mid-longitudinal position of the longitudinal part, and a step is provided such that the top surface of the first half 30a is higher than the top surface of the second half 30b. Yes, both subcommittees 30a
- The boundary part of 30b is the slope part 30c. The side wall of the front half portion 30a has an inward eave-like ridge 30 on its inner side.
d.30d is formed. These projecting edges 30d and 30d serve to prevent the second moving frame 29 from floating up from between the side walls 30 and 30 in both directions.

Reference numerals 32 and 33 indicate the lower side for holding the microfiche F, which is arranged and held in the large window frame on the rear side of the second movable frame 29.
These are two transparent plates (glass plate, resin plate, etc.) on the L side. The arrangement structure of the transparent plates 32 and 33 will be explained with reference to FIGS. 3 to 6.

The lower transparent plate 32 is disposed on the rear window frame portion of the second movable frame 29 via a pair of push-L springs 34 whose bases are fixed to the left and right frame sides, respectively. be.

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 33 is not applied, the force of the push-L leaf spring 34 causes the rear side of the lower transparent plate 32 and the The front side is pivoted using the abutting part with the stepped part 29a on the side of the frame 29 that receives the rear side as a fulcrum, and it is in a state where it floats from the frame part to a rearward downward slope plane attitude. .

(2) On the contrary, the side transparent plate 33 is closed and the lower side transparent plate 3
2, when the entire weight of the upper transparent plate 33 is applied to the upper transparent plate 3, the push-up plate spring 34 is pushed downward and fallen into the frame portion to be received, as shown in the third diagram.
3 and 3 are converted and maintained in a substantially horizontal position.

The leaf spring 34 pushes and holds the lower transparent plate 32 in a rearwardly downwardly inclined plane attitude of about 5° to 10° when the upper transparent plate 33 is opened, and when the upper transparent plate 33 is closed. The lower transparent plate 32 is made to have elastic properties that allow it to be pushed down and deformed until it completely collapses into the frame and is received.

The upper transparent plate 33 has a rotary member 35 integrally fixed along its length with adhesive or the like on the lower surface of the rear side thereof, and a rotary member 35 has a rotary member 35 integrally fixed at both left and right ends of the rotary member 35, respectively. Then, the pair of plate-shaped sliders 36 are integrally attached with screws 37 (FIG. 6). The left and right ends of the rotating member 35 and the left and right sides of the frame 29 are connected by shaft pins 39 that are supported in small holes 38 formed in the respective frames. 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 protrude above the left and right side walls 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 second half 30b-30b of 30 in the front and back direction.

Reference numerals 35a denote protrusions that are formed inwardly on both left and right ends of the rotating member 35 and serve as members for receiving and positioning the back side of the microfiche F placed on the lower transparent plate 32.

41, 41 (Fig. 7) are guides protruding from the left and right sides of the −L plane on the front side of the first movable frame 23, and 42 (Fig. 8) are the second movable guides corresponding to the positions of the guides. Guide engagement guide grooves are formed along the length of the frame sides at the lower surface positions of the left and right sides of the frame 29, and the second movable frame 29 is formed by the left and right longitudinal side walls 30, 30 on the first movable frame 23 side. It is guided in the front-back direction, and also by the engagement of the guide element 41 and the guide groove 42.

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 surface position of the upper surface plate 21 of the lower case 2.

If you face it and pinch the handle 43 with your fingers and operate it forward, backward, left and right,

・33 is the illumination light output light opening 11 and the imaging lens assembly 1
It moves in the plane direction, front and back, left and right with respect to the illumination part between 2 and 2 (X/Y movement).

When setting the microfiche F, pull out the second movable frame 29 forward so that the slider 36 is aligned with the side wall 30.
Slope portion 3 at the boundary between the front half 30a and the rear half 3ob 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 in the negative direction around the shaft pin 39 (FIGS. 4 and 8). Further, by opening the -1- side transparent plate 33, the lower transparent plate 32 is held in the backward downward inclined surface posture i by the push-up leaf spring 34 as explained in the above (1). Therefore, insert the microfiche F 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 microfish F onto the lower transparent plate 32 and insert the back side of the microfiche F into the rotating member 35 of the upper transparent plate 33. The lower transparent plate 32 is abutted against the positioning member 35a formed in the second movable frame 29, and the left or right side of the microfiche F is abutted against the inner surface of the left or right frame side of the second movable frame 29.
Position and place it at a predetermined placement reference position above. Since the lower transparent plate 32 is tilted downward in the direction of the positioning member 35a, this mounted microfiche F is stable without being displaced from the predetermined mounting reference position initially set, as explained in the section of the operation above. is maintained.

After placing the microfiche F, the second movable frame 29 is moved to follow. Then, the sliders 36, 36 move down from the slope portions 30c, 30c, and move toward the rear portions 30b, 30b of the side walls 30-30. As the sliders 36 move down from the slope @30cm30C, the upper transparent plate 33 closes and rotates about the shaft pin 39 with respect to the lower transparent plate 32. In the process of closing and rotating, the upper transparent plate 33 first collapses onto the lower transparent plate 32, which returns to the downwardly inclined surface position, and sandwiches the microfiche F placed on the lower transparent plate 32 as shown in FIG. The weight of the upper transparent plate 33 is applied to the lower transparent plate 32 due to the subsequent falling down, and as explained in the above (2), the root spring 34 is finally pushed downward as shown in the third figure. The lower transparent plate 32 including the upper transparent plate 33 falls down and is received by the frame, and is converted and held in a substantially horizontal position. In this way, the lower transparent plate 32 is held in the inclined plane position until the upper transparent plate 33 closes and rotates and the mounted microfiche F is pressed into the sandwich.
Even if shock or wind pressure occurs due to the closing operation of step 3, it will not easily move from the specified storage reference position, and the -L
It is stably held between the lower transparent plates 32 and 33.

When the upper and lower transparent plates 32 and 33 are in the closed state shown in the third figure, the sliders 36 and 36 are in the rear half portions 30b and 30b of the side walls 30 and 30.
As long as the second movable frame 29 slides within the length range along with the back-and-forth movement operation of the second movable frame 29, the -1- side transparent plate 33 is held without any rotational force acting on it.

Thereafter, in order to align the index 44 with the coordinate position corresponding to the target image frame address on the index plate 45, use the handle 43 to move the #S2 movable frame 29 in the front-rear direction Y-Y and the first movable frame 23 in the left-right direction. By moving in the direction of X--X, the target image frame portion in the microfiche F held between the upper and lower transparent plates 32 and 33 is located in the projection optical section. In FIG. 9, the index 44 is operated so as to correspond to the coordinate D5 of the index plate 45, and the coordinate D5 is

The configuration of means for converting the tilted surface attitude of the lower transparent plate 32 when the upper transparent plate is open and converting the substantially horizontal attitude when the upper transparent plate is closed is other than the push-in plate spring 34 of the embodiment described above. There are various possibilities. 1O to 12 show another example in which a cam is used instead of the leaf spring 34 to perform the above-mentioned changing operation.

In the figure, reference numeral 46 denotes a lower transparent plate riding slope cam member disposed on the left and right frame sides of the first movable frame 23, and the second movable frame 29 is moved forward in order to open and operate the upper transparent plate 33.

When the microfiche F is placed on the lower transparent plate 32 and the second movable frame 29 is moved backward, the upper transparent plate 33 first closes and rotates during the retreating process, and is still on the slope cam member 46. The lower transparent plate 3 is tilted downward at the rear.

It is held on the movable frame 29 in a substantially horizontal position. During this time, the sliders 36, 36 separate from the slope portions 30c, 30c, and the edge of the upper transparent plate 33 is cut, and the upper transparent plate 33 is closed in a substantially horizontal position with the microfiche F sandwiched on the lower transparent plate 32. Become.

Incidentally, on the second movable frame 29 side, a groove is formed for receiving the slope cam member to avoid interference with the slope cam member.

FIG. 13 shows an example in which a member 13a for receiving and positioning the back side of the microfiche F is provided in the form of a pair of projections 35a' 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.

Figure 14 shows a horizontal frame on the front side of the lower transparent plate so that the microfiche F can be smoothly inserted and removed onto the lower transparent plate 32 with the upper transparent plate open. This is an example in which the upper surface of the side 31 is a microfiche sliding guide concave curved surface 48 or an inclined surface.
