Abstract

PURPOSE:To improve efficiency for retrieval by successively storing the film position of a picture desiring printing during manual retrieval and continuously printing the picture after the retrieval. CONSTITUTION:When the manual retrieval is executed by using a velocity setter 114, a film feeding control means 122 feeds the film to a target position and calculates a traveling amount to the frame of the picture under displaying by using the output of an encoder 66. When the picture desiring printing appears, a traveling amount L at that time is successively stored in a memory 110A by depressing a keyboard 112A. When the manual retrieval is finished and a print execution key 112B is depressed, a printing control means 126 reads out the film position of the print desiring picture from the memory 110A and executes printing through the means 126 by the means 122. Thus, the efficiency for the retrieval is improved.

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a microfilm reader link in which a roll of microfilm is used to manually search and print a desired image.

(Technical Background of the Invention) A conventional device of this type that performs manual searching is such that when an image that needs to be printed appears while searching manually, it is printed by pressing the print button, and after printing is completed, the next image is printed. The purpose was to search for images. In other words, the next image cannot be searched until printing is finished, and the operator has to wait during that time. For this reason, there was a problem that search efficiency deteriorated.

(Object of the Invention) The present invention has been made in view of the above circumstances, and a first object of the present invention is to provide a printing method that can improve search efficiency when manually searching and printing necessary images. The purpose of

A second object is to provide a printing device that can be used directly to implement this method.

(Structure of the Invention) According to the present invention, the first object is to sequentially memorize film positions of images desired to be printed during manual search in a microfilm reader printer capable of manual film search. This is achieved by a printing method for a microfilm reader printer, which is characterized in that the print control means subsequently sequentially feeds the film to the memorized film positions and prints continuously.

The second object is to provide a microfilm reader printer capable of manual film retrieval, with a film feed control means for feeding the film to a target position, a film travel amount detection means, and a memory readout based on a manually inputted memory command signal. memory means for detecting and storing the film position of the image in the image from the film travel amount detecting means; and a target for reading the film position stored in the memory means based on a manually inputted print execution command signal and controlling the feed control means. This is achieved by a printing device for a microfilm reader printer, which is characterized in that it is equipped with a position and a printing control means for causing the printing device to execute printing.

(Example) Fig. 1 is an overall schematic diagram of an embodiment of the present invention, Fig. 2 is a perspective view of a part thereof, Fig. 3 is a system diagram of its control signals, and Fig. 4 shows only the main parts. The conceptual diagram and FIG. 5 are operation flowcharts.

The roll microfilm 2 used in this embodiment is housed in a cartridge 8 (FIGS. 1 to 3) and loaded into the reader/printer device 10.

The reader/printer device 10 is configured as shown in FIG. That is, the front of the case 12 (right side in Figure 1)
A transmissive screen 14 is arranged on which images of the frames of the film 2 are enlarged and projected. The cartridge 8 is loaded into a loading section 16 located below the screen 14. The leading end of the film 2 wound on the supply reel 18 in the cartridge 8 is pulled out by a loading mechanism and wound on the take-up reel 20.

A light source 22 is arranged below between both reels 18, 20. The light emitted from the light source 22 passes through the film 2 and is guided to the screen 14 via an optical system including a projection lens 24, an image rotation prism 26, a plurality of reflection mirrors 28, 30, 32, and the like. As a result, the image information recorded on one frame of the film 2 is enlarged and projected.

A mirror 34 that can be moved back and forth on the optical axis is provided between the reflecting mirrors 28 and 30, and during printing, image projection light is directed to a printer device 36 located below by this mirror 34.
lead to. Note that this printer device 36 is, for example, of a PPC type, and forms an electrostatic latent image of an image by exposing a photosensitive drum 36a (see FIG. 3), and makes a visible image by adhering toner to this latent image. , which is transferred onto printing paper and fixed. Moreover, this blinking device 36 is
A masking device 38 is provided to block the incidence of projection light, and particularly in the case of a negative film, it blocks the incident light that would create a black border in the image.

The film advance mechanism is shown in FIG.

When the cartridge 8 is loaded into the loading section 16, the microswitch 40 detects this, and the CPU 102 (described later) activates the loading mechanism.

That is, a roller (not shown) is brought into rolling contact with the reel 18 through an opening 8a provided at the bottom of the cartridge 8, and the leading edge of the film 2 is pulled out and wound onto the take-up reel 20 via guide rollers 42, 44. Sensors 46, 48 for detecting the presence or absence of the film 2 are arranged near the guide rollers 42, 44.

An endless belt 50 is pressed against the winding wheel 20 and tightly contacts the film 2 being wound there. This endless belt 50
are guide rollers 52, 54, 56 and drive rollers 58
is wrapped around. The drive roller 58 is driven by a motor 60 and causes the belt 50 to run in the direction of arrow A, that is, in the winding direction. As a result, the film 2 is wound onto the reel 20 while being sandwiched between the belt 50 and the reel 20. Note that the rotation shaft of the motor 62 is automatically connected to the supply reel 18 when the cartridge 8 is loaded. The rewinding of the film 2 is performed by driving the reel 18 in the right direction of the arrow by the mokro 2. At this time as well, the belt 50 runs together with the film 2.

A tension roller 64 is pressed against the endless belt 50 with a predetermined pressure to apply appropriate tension to the belt 50.

The rotation speed of the tension roller 64 is detected by an encoder 66. Based on the output pulse signal of the encoder 66, the running amount of the endless belt 50, that is, the running amount of the film 2 is determined by the CPU 102, which will be described later.

In this embodiment, manual search and automatic search can be selected, and in the case of automatic search, film advance is controlled using a grip (document mark) provided on the film 2. The blip provided on the film 2 here is the light source 22
is detected by two sets of light-emitting elements 68 (68a, 68b) and light-receiving elements 70 (70a, 70b) located a certain distance β apart from the optical axis C of the supply reel 18. Of the light emitted from the light emitting element 68 , only the light passing through the grip is selected by the slit 72 and guided to the light receiving element 70 . The outputs of these light-receiving elements 70 are input to the CPU 102, and frames that have passed under the light-receiving element 70 are identified by integrating the types of blips and the number of passages. Since the distance between the detected blip position and the optical axis C is constant β, by monitoring the amount of film travel detected by the encoder 66, the frame being projected can be identified.

That is, when a blip of a target frame is detected, the target frame will be placed within the optical axis C by feeding the film 2 further toward the take-up reel 20 by a distance β.

In the case of manual search, the film position is controlled by a speed setting device 114, which will be described later.

The image information of the target frame that has entered the optical axis C in this manner is projected onto the screen 14. Projection lens 2 here
The magnification of 4 is variable by a motor 74, and the rotation angle of the image rotating prism 26 is variable by a motor 76 (FIG. 3).

Behind the screen 14, the CCD line sensor 78 is held by a movable plate 80, and the movable plate 80 is movable left and right on guide rails 82 and 84. This movable plate 80 has a pair of pulleys 86.8 as shown in FIG.
Both ends of the wire 90 wound around the wire 8 are fixed.

The pulley 88 is rotated by a motor 92, and a wire 90 running therewith moves the movable plate 80 left and right.

Next, the control device 100 will be explained based on FIG. The control device 100 includes a digital arithmetic unit (hereinafter referred to as CPU) 102 and input/output interfaces (I/F) 104 and 106.
, a ROM 108 for storing operating programs, etc., and a RAM 110 for storing image signals read by the line sensor 78, various data, etc. Various signals are input to this CPU 102 via an input I/F. For example, the image signal a read by the line sensor 78, the output signals of the microswitch 40, the sensor 46, 48, the light receiving element 70, the encoder 66, etc. are input. Also keyboard 1
From 12, a memory command signal, a print execution command signal, an identification code of a target image, an identification code of an image to be printed, etc., which will be described later, are input.

114 is a manual speed setting device for moving the film to a target position, and is used to input the feeding direction and feeding speed of the film 2. The operation knob 116 of this speed setting device 114 has a habit of returning to the neutral position, and if it is rotated from the neutral position to the left or right, the amount of rotation will be
02. The CPU 102 uses this operation knob 11
The feeding direction and speed of the film 2 are controlled in accordance with the direction and amount of rotation of the film 6 from the neutral position. That is, operation knob 1
At the neutral position of 16, the film 2 is stopped, and when turned to the left, the motor 60 is activated to move the film 2 to the left in FIG. 3, and when turned to the right, the motor 62 is activated and the film 2
drive to the right.

Reference numeral 118 denotes a liquid crystal display panel, which displays the amount of film travel in terms of distance from the front edge of the film, as will be described later. That is, by adding and subtracting the output pulses of the encoder 66, the travel distance is determined and displayed on the display board 118.

Reference numeral 120 denotes a digital blinker, which prints an image read by the line sensor 78 as necessary, or connects another reader printer device to the CPU 102 and prints an image sent from another device to this printer 120. You may also output it.

The CPU 102 has the functions shown in FIG. First, when the operator performs a manual search using the speed setting device 114 (fifth
2, step 200), the film feed control means 122 of the CPU 102 feeds the film to the target position at the speed set by the speed setting device 114. During this search, CPU10
The traveling amount detecting means 124 of No. 2 continues to obtain the traveling amount L (distance) from the leading edge of the film to the frame of the image being displayed by adding and subtracting the output pulses of the encoder 66 as described above. When the image desired to be printed appears, the operator presses the memory command key 112A on the keyboard 112 (step 202). The memory command signal input by this operation stores the amount of travel at that time in the memory means 110A.
(step 204). This memory means 1
10A is constituted by a part of the RAMll0. In this manner, the operator presses the key 112A when a desired image appears while searching manually, and the film position of that image is sequentially memorized as the travel distance. When the manual search is completed (steps 206 and 208), the operator presses the print execution key 112B on the keyboard 112.
The print control unit 126 of the CPU 102 inputs the print execution command signal C to the CPU 102 (step 210). Based on this signal C, the print control unit 126 determines the film position (
The amount of travel L) is read (step 212), and the film is sent to this position (target position) by the feed control means 122 (step 214). Further, when the film reaches this target position, this means 126 sends a print command d to the printing device 36 to execute printing (step 216).
). The print control means 126 repeats the operations of steps 210 to 216 for all film positions stored in the memory means 110A (step 218).

(Effects of the Invention) As described above, according to the first invention described in claim (1), the film positions of images desired to be printed are sequentially memorized during manual search, and the film positions of images desired to be printed are sequentially stored in memory after the search is completed. Since the film is sequentially sent to the memorized film position and printed continuously, there is no need to wait for printing to finish when searching, and the search can be performed efficiently. Also, if the operator prints while he/she is away from the device, no time is wasted.

Further, according to the second invention described in claim (2), a printing device that is directly used for implementing the first invention is obtained.
