Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a search device for searching card-like films such as microfiche and microjackets.

(Prior art) In a reader that projects an original image of microfiche, microjacket, etc. onto a screen and reads it, a card-like film such as microfiche is supported on a carrier table, and the carrier table is moved by an electric mechanism. A retrieval device is used that is driven and moves a target frame to a projection position. This type of search device has a function of automatically moving a designated frame to a projection position or sequentially moving one frame at a time to a projection position by operating a single key. By the way, with guard-like films such as microfiche and microjacket, the frame position may be slightly misaligned depending on the film, and in some cases, the frame may be slightly misaligned.
Since it is necessary to project a specific part of the film, such as a part spanning two frames, the above-mentioned retrieval device moves the position of the card-shaped film little by little and makes fine adjustments to obtain the desired projected image on the screen. It has functions.

Conventionally, there are the following fine adjustment mechanisms for this type of card-shaped film retrieval device.

(b) A device that allows fine adjustments to be made by manually moving the carrier table that supports the card-shaped film.

(b) The keymate that moves the carrier table carrying the card-like film is provided with a fine adjustment key, and by operating this fine adjustment key, the carrier table is slowly moved vertically or horizontally at one foot speed by an electric mechanism. Move it in the direction and make fine adjustments.

(Problems to be Solved by the Invention) However, such prior art has the following problems.

In the case of (a) manual operation, a rotating and sliding mechanism is required for fine adjustment, making the mechanism complicated. Since it is done manually, the moving speed of the carrier table can be adjusted arbitrarily, but card-shaped films have different scale rates υ depending on the film, and accordingly, film formats such as the number of frames differ, so film formats with high scale rates and a large number of frames When projecting a card-like film, it is necessary to use a high-power lens.

In this case, the image on the screen moves widely due to the effects of camera shake, making fine adjustment difficult and requiring skill.

In the case of (b) electric operation, the carrier table moves vertically or horizontally as long as the fine adjustment key is pressed, and stops when the key is released, so anyone can easily operate it. Since the carrier table moves at a constant speed regardless of the magnification of the lens, the speed of image movement on the screen varies depending on the magnification of the projection lens. Therefore, in order to project a card-like film with a high scale and a large number of 7 frames, it is necessary to use a lens with high magnification. In addition to being difficult to match, when searching for a long time, the user's eyes may become tired or become seasick. Conversely, in order to project a card-shaped film with a low scale and a small number of frames,
A lens with low magnification is used, and in this case, the image movement speed on the screen is slow, so it takes a long time to adjust the frame position.

The present invention was made in order to solve the problems of the prior art, and its purpose is to make the image movement speed on the screen substantially constant during fine adjustment, regardless of the magnification of the projection lens. By controlling the moving speed of the carrier table depending on the film form of the card-like film, frame alignment becomes easy and quick, regardless of the magnification of the projection lens, when making fine adjustments to the positional movement of the card-like film. To provide a card-shaped film retrieval device that can be used on time and prevents eye fatigue and seasickness.

(Another Means to Solve the Problems) Therefore, in order to achieve the above object, the present invention provides a first carrier table that is attached to a carrier base so as to be movable in a first direction, and a first carrier table that is movable in a first direction. a second carrier table that supports a shaped film and is attached to the first carrier table so as to be movable in a second direction different from the moving direction of the second carrier table, and drives the first carrier table and the second carrier table. a frame specifying means for specifying a frame of the card-like film; a control means for controlling the drive means to bring the frame designated by the frame specifying means to a projection position; The apparatus includes a film form information manual means for manually inputting film form information of a shaped film, and is configured to control the moving speed of the first and second carrier tables during fine adjustment based on the film form information.

As shown in FIG. 4, it consists of a delay switch 34 arranged on the back side of a case 33 of the operating section 3. The delay switch 34 converts the film format signal consisting of a 3-bit digital signal into CP according to the film format such as the number of frames of the card-like film F, as shown in Table 1.
Send it to U18. The CPU 18 performs arithmetic processing based on the film format signal in accordance with a pre-installed GLODARAM, and adjusts the drive pulses output from the CPU 18 to the driver 17 to adjust the timing when the fine adjustment keys 20 to 23 of the operation unit 3 are operated. X direction carrier table 8 and Y
Controls the moving speed of the direction carrier table 9.

Margin below Table 1 It is.

In the above configuration, the card-shaped film search device according to the present invention searches for card-shaped films in the following manner. First, by turning on the power switch 30 of the power supply unit 4, the operation unit 30CPU1B is activated to move the X-direction carrier table 8 and the Y-direction carrier table 9 to the reference position. The direction of movement is determined by whether or not the X-direction reference position detection member 11 and the Y-direction reference position detection member 13 are connected to the X-direction sensor 12 and the Y-direction sensor 14, respectively. For example, if the X-direction carrier table 8 and the Y-direction carrier table 9 are in the positions shown in FIG. 1 when the power is turned on, then
Since the Y direction reference position detection member 11.13 is not present in the X and Y direction sensors 12.14, each carrier table 8, 9 is moved in the -X and -Y directions, and each detection member 11
．． 13 is applied to each direction sensor 12.14, X.

The movement of the Y-direction carrier tables 8 and 9 is stopped.

When the carrier tables 8 and 9 in the X and Y directions are moved to the reference position in this manner, input from the operating section 3 is accepted. (However, at this time, the fine adjustment keys 20 to 23 and the - frame advance key 27 floor are not accepted.) First, the Eso Ext key - 25
When is pressed, a signal is sent from the CPU 18 to the driver 17, the Y-direction carrier table 9 moves to the eject position, and the upper supporting member 10 opens. Then, a desired card-like film F is placed at a predetermined position on the lower supporting member 10, and the upper supporting member 10 is closed to set the card-like film F. Next, when the index key 24 is pressed, the X direction carrier table 8 is used to hold the index frame of the card-like film F at the projection position.
When the address designation key 26 is pressed to specify an address, the carrier table 9 is moved in the
Direction carrier table 8 and Y direction carrier table 9
move. To specify an address, for example, pressing the 9 address designation key moves the 9th column of the card-like film F to the projection position, and pressing the E address designation key projects the E row of the card-like film F. Finally, the frame in the 9th column and row E of the card-like film F is moved to the projection position.

After this movement, when the fine adjustment crab keys 20 to 23 are pressed, the X direction carrier table 8 moves in the opposite direction to the direction indicated by each arrow.
Or, the Y-direction carrier table 9 moves at a slow speed (however, when the card-like film F is projected on the screen,
The image on the screen moves in the same direction as the arrow). This moving speed is determined by the CPU 18 as follows based on the film form signal from the film form information input means 32 so that the moving speed of the image on the screen is approximately constant even if the magnification of the projection lens is different. Ru.

That is, the CPU 18 inputs the film format information input means 3.
When the film format signal is sent from No. 2, as shown in FIG. 5, the timer count number N is first set by the film format signal in an N setting routine (step 2). Next, it is determined whether or not the fine adjustment distortion keys 20 to 23 on the operation unit 3 have been pressed (Step 2). If they have not been pressed, φF and timer variable T are cleared in the key flag and the process returns (Step 2). ). If fine adjustment keys 20 to 23
If is pressed, it is determined whether K-F is 1 or not in step ■). In this case, F=0, so -
Set F=1 (step ■). Next, timer f number T
Clear step ■) and return to step ■. At this time, if the fine adjustment key remains pressed, the process proceeds to step (2), and since @F=1 this time, the process proceeds to step (2). At this time, since the timer variable T is 0, the timer variable T is set to 1 and the process returns to step (2). And step ■ → steg ■ → step ■ → step ■
→ Steg ■ is repeated several times to sequentially increment the timer variable T, and only when the timer variable T becomes equal to the timer count number N set in step ■, does the process proceed to step ■. Here, in order to move the X-direction carrier table 8 or the Y-direction carrier table 9 in the direction input with the fine adjustment key, the CPU 18 outputs one drive pulse to the driver 17. Then, after clearing the timer variable T (step [shares]), step ■ → Steg ■ → Step ■ → Steg ■ → Steg ■
This is repeated, and after a certain period of time has elapsed, the CPU 18 outputs a drive pulse for one pulse. Fine adjustment keys 20-23
Only while is pressed, the X-direction carrier table 8 or Y-direction carrier table 9 moves in the predetermined direction as described above.
It moves at a moving speed determined by the interval of drive pulses output from the CPU 18 to the driver 17. This moving speed, that is, the interval between driving pulses, is determined by the film form information input means 32. It is determined by the timer count number N set in response to the film format signal from . The relationship between the Fi/l/4Kl 'l- signal and the timer count number N is programmed in advance in the ROM (not shown) in the CPU 18 so that the moving speed is approximately constant regardless of the Fi/L 4 type. ing.

As described above, when the fine adjustment keys 20 to 23 are pressed, the CPU 18 performs glodulum processing based on the film format signal from the film format information input means 32, and adjusts the interval of drive pulses output to the driver 17. The moving speeds of the X-direction carrier table 8 and the Y-direction carrier table 9 during fine adjustment are controlled so that the image moving speed on the screen is substantially constant regardless of the film form of the card-like film.

Furthermore, by pressing the one-frame feed key 27 on the operation unit 3, it is possible to move the - frame (move one frame at a time), and by pressing the eject key 25, the Y-direction carrier table 9 can be moved to the eject position. Of course, it is also possible to open the supporting member 10, take out the card-like film F therein, and replace it.

In the illustrated embodiment, the film format information input means 3
2, a case has been described in which the delag switch 34 is used to input a day signal according to the film format, but the present invention is not limited to this. You can also
In addition, any configuration may be used as long as the film format information can be input to the CPU 18.

Further, in the illustrated embodiment, the film form information input means 3
The case has been described in which the moving speed of the X-direction and Y-direction carrier tables 8 and 9 during fine adjustment is controlled by adjusting the interval of drive pulses output from the CPU 18 to the driver 17 using signals from the CPU 18. The CPU 18 is activated by a signal from the film form information input means 32 to change the speed ratio of the drive means 15 equipped with a pulse motor, thereby controlling the moving speed of the X-direction and Y-direction carrier tables 8 and 9 during fine adjustment. You can do it like this.

(Effects of the Invention) The present invention has the above-described structure and operation, and since the moving speed of the carrier table during fine adjustment is controlled depending on the film form, projections that can be exchanged depending on the film form of the card-like film are provided. Regardless of the magnification of the lens, the image movement speed on the screen can be maintained at an appropriate speed, making it easy to align the frame and preventing eye fatigue and seasickness. be able to. Further, even when a low-magnification projection lens is used, the moving speed of the image on the screen does not slow down, so there are various effects such as frame positioning can be performed in a short time.
