Abstract

PURPOSE:To retrieve frames quickly though an operator does not memorize the number of a current frame when he retrieves a microfiche which is photographed halfway in each row or column, by providing a row feed key and a column feed key. CONSTITUTION:A device which retrieves the microfiche in accordance with address designation from a keyboard normally is provided with a row feed key 23 and column feed key 24; and when they key 23 (or 24) is depressed, a CPU21 moves the microfiche by one row (or one column) with respect to the current address, and the processing for offsetting of row (or column) (by address one or A) is performed. A required extent of movement from the current position to the target position of movement due to row feed is calculated, and a program is written in the CPU so that pulses required for this movement are transmitted to a pulse motor driving circuit 22. For example, if a frame A6 is unphotographed, the first frame B1 in the next row is retrieved automatically when the row feed key 23 is depressed.

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) A moving member, etc. By controlling the movement of the radial moving member, the set microfiche is moved two-dimensionally, and the required image frames are 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 frame portion of a frame on an optical path 1 of a projection optical system.

[Conventional technology]

Conventional devices of this type have a method of specifying a frame during a search by using a keyboard to specify movement to the fish carrier using a row of letters and a string of numbers, as shown in A3.85 shown in Figure 1, and a method shown in Figure 2. The next frame after the currently sick frame (keyboard operation: press the ÷1 key), or the previous frame (keyboard operation: a↓-1/?lA--Yaba-4-1-)
m MQ Woo J- A2・A3...A5
・When searching for B1, B2, etc., if the operator does not know the projection form of the fish being searched for, after A5, specify 88 or next frame key +1 to search for 80, and then search for 80 on the screen. If it is not projected, it specifies the next matrix old.

[Problem that the invention seeks to solve]

However, when 80 is searched, nothing is projected on the screen, so the current position cannot be confirmed.Therefore, unless the operator memorizes the current position, the next line will not be known as an alphabetic letter, so the operator cannot confirm the current position by memorizing the current position. Press the key to return to the previous frame (A5 in the above example), confirm that you are on row A, and then press B.
1 must be specified, which has the drawback of being troublesome and time-consuming.

Structure of the Invention Means for Solving Problem C] In the microfiche retrieval device as described above, there is a new line key or a new line return key for returning to the beginning of the next row or next column of the frame currently being searched. A search program is written in which a column key is provided in the key input section, and when the line feed or line feed key is pressed, an arithmetic processing program that moves and offsets the current address by one row or column, respectively.
It is incorporated into Pu.

[For production]

In the above example, if you specify the next frame A6 and find that no image is projected, press the line feed or line feed key to automatically return to the previous row or column, so the current frame address The return operation will be performed immediately even if it is not remembered.

〔Example〕

Figure 6 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 by a carrier C, and everything from the imaging lens 6 to the screen 9 is built into a dark box. Pooling may be configured by guiding the above projection optical path to a copying machine.

FIG. 7 shows an example of a device for moving the carrier C two-dimensionally in the X-Y direction, where lO is a substrate fixed to the main machine box 1. 10aelOb is a left and right side wall of the board 1O, 11 is a screw rod in the left and right direction (X direction) that is rotatably supported by a bearing between the rear ends of the left and right side walls, and 12 is also mounted and held at the front end section.

A guide rail parallel to the threaded rod 16 has its left side threadedly supported by the threaded rod 14, and its right side is slidably supported by the guide rail 15.The second frame 1M-Y is a guide rail parallel to the threaded rod 14. The Ml frame 13 is attached to and held by a Y-direction drive motor such as a pulse motor that drives the ML frame 13 in forward and reverse directions.

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

Figure 4 is the above '! This is a block diagram of an electric circuit that controls the Jc position. CPU board 21° motor drive circuit 22. Consists of motor M-X@M-Y. A large number of key signals from the key input section 20 are all input to the CPU in a matrix.

When you specify the frame image position using the frame image specification key,
The CPU calculates the rotation angles of the pulse motors M-X and M-Y corresponding to the amount of movement of the carrier C according to the written program, and the rotation angles of the pulse motors M-X and M-Y corresponding to the amount of movement of the carrier C are calculated, and the rotation angles of the pulse motors M-X and M-Y are
The pulse motor M-X-M-Y of Y is driven, thereby controlling the movement of the first and second frames 13 and 16, that is, the carrier C, in the X and Y directions, respectively, and clamping and setting them on the transparent plates Gl and G2. The designated frame image within the plane of the microfiche F is automatically searched and positioned directly below the lens 6.

The present invention provides an apparatus for searching for microfiche by normally specifying an address from a keyboard as described above.
A line feed key 23 and line feed key 24 are provided, and when the keys are pressed, the CPU 21 returns the current address to
Move each row (and column) one step, then column (and row)
is calculated to offset (L address or A address), and then calculates the amount of movement required from the current position to the position to be moved by line feed, and the pulse motor drive circuit 2
2, a program is written into the CPU so as to send out the necessary number of pulses for that purpose.

That is, if frame A8 in the above example has not been photographed, the configuration is such that when the line feed key 23 is pressed, the first frame Bl of the first line is automatically searched.

In order to cope with a type of fish that is photographed in sequence in the vertical direction as shown in FIG. 4, a key may be provided to change the number rows so that the first row of numbers is followed by the second row, then the third row, and so on.

C. As described in the detailed explanation of the invention, by providing the line feed and line feed keys, when searching for microfiche that has only been photographed halfway in each row or column, the operator can select the frame where the operator is currently located. You can search quickly even if you don't remember the number.

Furthermore, even if the operator knows in advance that only up to A5 is projected, he only has to press one line feed key, which is faster than if he had to press two keys, B and 1. Can be searched. Moreover, it has the effect of requiring fewer keys to be pressed.
