Description

Detailed Description of the Invention A. Object of the Invention [Field of Industrial Application] The present invention provides a microfiche projection device (league, league printer, etc.) in which a member moving in the left-right direction (X) and a member moving in the front-back direction ( Y) The set microfiche is two-dimensionally moved by controlling the movement of the removable member, and the desired frame is selected from among the numerous image frames imprinted in a vertical and horizontal pattern on the surface of the microfiche. The present invention relates to an electric microfiche retrieval device for retrieving and positioning a portion on the optical path of a projection optical system.

[Conventional technology]

For this type of microfiche, the frame position can be designated by a combination of alphabetic characters in rows and numbers in columns (matrix designation method), as shown in the first diagram, or by serial numbers, as shown in the second diagram. There is a method using numbers (number symbol designation method).

[Problem that the invention seeks to solve]

Therefore, when using these in the same search machine, for example, if you want to search for the frame "12" in the number symbol designation method (B) in Figure 2, B3" in the matrix designation method (A) in Figure 1. The disadvantage is that it is very troublesome and time-consuming because you have to check that it is compatible and enter it on the keyboard.

This invention aims to eliminate the above-mentioned drawbacks.

1. Configuration of the Invention [Means for Solving the Problems] The present invention provides an electric microfiche retrieval device as described above, in which a signal from a key input section of a keyboard is used.
The computer (CPU) board section that controls the drive circuit in the X-Y direction according to the written program and drives the drive motor in the -B is written, and the key input section is provided with a switch for selecting the specifying method, so that the programs for the above specifying methods A to H can be used properly.

[For production]

When a switching signal for frame position designation method A-B is input to the key input section, the CPU board reads it and selects the designated program A or B. Thereafter, the CPU board calculates the amount of movement from the current position to the designated frame based on the information input from the keyboard, and then outputs pulses corresponding to the amount of movement to each X@Y pulse motor drive circuit,
The pulse motor moves the microfiche F to the designated frame.

〔Example〕

Figure 5 illustrates the projection optical system of Microfiche F, where 3 is a light source consisting of a lamp and a reflector, 4 is a reflecting mirror, 5 is a condenser lens, 6 is an imaging lens, 7 and 8
is a reflecting mirror, and 9 is a screen.

A microfiche F is placed between lenses 5 and 6, and is searched and moved using a carrier C.

Everything from the imaging lens 6 to the screen 9 is built into a dark box. In some cases, the above projection optical path is guided to a copying machine to constitute a printer.

FIG. 6 shows an example of a device for moving a carrier C two-dimensionally in the X-Y direction, where lO is a board fixed to the main machine box l. 10a and 10b are the left and right side walls of the board IO, 11 is a screw rod in the left and right direction (X direction) that is rotatably held by a bearing between the rear ends of the left and right side walls, and 12 is also attached between the front ends. 13 is a vertically elongated first frame whose rear side is screwed and supported by the screw rod 11 and whose front side is slidably supported by the guide rail 12. , M-X is an X-direction drive motor such as a pulse motor that drives the screw rod 11 in forward and reverse directions.

Reference numeral 14 denotes a screw rod in the front-rear direction (Y direction) that is rotatably held on a bearing near the left frame side between the back side horizontal frame side 13a and the front side horizontal frame side 13b of the first frame body 13, and 15 is the right side horizontal frame side 13b. The mounting was kept close to the frame edge. A guide rail parallel to the above screw rod,
16 is screwed and supported on the left side by the threaded rod 14, and the right side is mounted on the first frame 13 by a Y-direction drive motor such as a pulse motor that drives the threaded rod 14 in the forward and reverse directions. It's a shame.

The microfiche F is held between a lower transparent plate G2 fixed to the rectangular second frame 16 and an upper transparent plate Gl that can be opened and closed.

FIG. 3 is a block diagram of an electric circuit that controls the above device, and shows the key input section 20. CPU board 21, motor drive circuit 22. Consists of motor M-X@M-Y. Key input section 20
A large number of key signals are all input to the CPU in a matrix.

When you specify the frame image position using the frame image specification key,
The CPU is set to carrier C by the written program.
The rotation angle of pulse motor M-X-M-Y corresponding to the amount of movement is calculated, and the rotation angle of pulse motor M-X-M-Y corresponding to the amount of movement of
・The pulse motor M-X@M-Y of Y is driven, and the first and second frames 13 and 16, that is, the carrier C, are controlled to move in the XφY direction, respectively, and are clamped and set on the transparent plates G1 and G2. w1'ii in the plane of microfiche F!
Both frame images are automatically searched and positioned directly under the lens 6.

In the present invention, a program A for a matrix designation method and a program B for a numerical symbol designation method are written on the cPυ board 21 mentioned above. Further, the key input section 2° is provided with a switch (switch key) 20a for changing the designation method.

The dip switch (
(not shown) to correspond to method A, C
The PU21 reads the switching signal and program A operates, pressing the keys on the keyboard such as "C", "3", "
When you press "Enter," the CPU executes program A and executes C3.
The number of pulses required to move up to the point is calculated, and frame 03 of the microfiche in FIG. 1 is searched.

Similarly, if you change the dip switch to correspond to method B, program B will be activated and the key will be pressed, for example 2","
1" and press "Enter", the number of pulses required to move up to 21 is calculated by program B using cpυ, and 21 frames of the microfiche shown in FIG. 2 are searched.

The specification method selection switch 20a in the above embodiment may be any means as long as it changes the electric circuit, and the timing for reading the selection switch is not limited to after a key scan, but may also be when the power is turned on or when replacing the fish. M-X-M-Y is outside the pulse motor A, C, motor, O
, C motor, linear motor, etc. may be used.

C. Effects of the Invention Since the present invention has the above configuration, it is possible to search for two types of microfiche, one for matrix designation and one for numerical symbol designation, using a common search device by simply switching the designation. This has the effect of omitting the trouble of converting numbers and symbols.
