Abstract

PURPOSE:To easily execute an input for editing an image, by attaching a transparent sheet-shaped partial copy information input means onto a screen, pressing the partial copy information input means with a point pen, etc., by seeing an image which has been projected to the screen, and inputting the image information. CONSTITUTION:When an image is being projected to a screen 22 of a reader printer body 21 at the time of a reader, a desired copy range is instructed by pushing points I-IV with a point pen 31, and subsequently, a desired image processing form ('trimming', in this case) is instructed. As a result, coordinates (x), (y) corresponding to the points I-IV and the image processing form are inputted to an editor CPU7. In this regard, an input for editing an image can be executed only at the time of a reader, and the input cannot be executed by a control signal from a body CPU8 in the course of a printing operation. A polarity signal of printing is inputted to the body CPU8 from a changeover switch 9.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reader printer used for enlarging and projecting an image recorded on a microfilm onto a screen or a photosensitive surface for reading and reviewing.

Conventional technology In recent years, league printers that handle microfilm have been using microfilms, as the information recorded on the microfilm itself has many secret elements. There is an increasing desire to obtain a hard copy of only the necessary portion of information.

Conventionally, in copying machines, images are cropped.

Editors that perform image editing such as erasing and moving are already commercially available, but no reader printer has such an editor, and only a partial copy function that copies only the necessary area of the image projected on the screen is available. It is known that the device was made to have a

Problems to be Solved by the Invention However, in conventional league printers having a partial copy function, the copy area is specified by button operation, and the copy area is displayed using light emitting diodes (LEDs) provided at the periphery of the screen. Alternatively, a light-shielding member that can be moved in and out of the projection optical path is disposed near the exposure position of the photoreceptor, and a display member that displays the position of the light-shielding member on the screen is displaced in relation to the movement of the light-shielding member. The copy range was displayed by member.

However, conventional league printers of this type have a small degree of freedom functionally in specifying the copy range, etc., or require a mechanism to displace the display member in relation to the movement of the light shielding member, resulting in a complicated configuration. The problem was that it was complicated.

Although not specifically shown, the second mirror 40 is pivoted at the rear and has a league use position (A) shown by a solid line in which the projection optical path is directed toward the screen 22 via the third mirror 42, and a printer optical system 36. In order to make printing possible, the printer can be switched between a printer use position (b) shown by a dashed line in which the printer is retracted from the projection optical path of the first mirror 38 and directs the projection optical path to the fourth mirror 44.

The printer optical system 36 faces into the projection optical path from the projection lens 26 and scans back and forth within the league printer main body 21, and includes the first mirror 38 and the first A fourth slit exposer directs the scanning light from the mirror 38 toward the photosensitive drum 34.
It consists of a mirror 44 and a fifth mirror 46 that directs the projection optical path from the fourth mirror 44 toward the photosensitive drum 34. The 11th and 4th mirrors 38 and 44 are the same moving table (not shown).
It is equipped with a scanner and scans it as a unit.

A cleaning device 54, an eraser lamp 56, etc. are arranged to form an electrostatic latent image by slit exposure of the projected image on the surface of the photosensitive drum 34, to make it visible by developing it, and to copy the visible image on the photosensitive drum 34. It is now possible to transfer onto paper.

In the present invention, in order to enable image editing, a shutter unit 60 whose structure is shown in FIG. 9 and FIG.
I as shown in a) and (b).

Light emitter array 6 using ED (light emitting diode) as a light emitter
2 are arranged.

When a positive copy image is obtained when the microfilm is a negative film (hereinafter abbreviated as NP), image editing is performed by controlling the developing bias in the shutter unit 60 and the developing device 11.

Contrary to the above, when obtaining a positive copy image when the microfilm is a positive film (hereinafter abbreviated as P-P), the individual light emitting elements of the light emitting array 62 are turned on and off. Image editing is performed by the control.

As shown in FIG. 9 and FIG.

It is equipped with

The shutters 66 and 68 have guide rods 8 disposed outside the photosensitive drum 34 in the axial direction of the photosensitive drum 34.
z, the guide rod 82 is supported by guide tubes 66a and 68a which are slidable in the axial direction of the guide rod 82 and fitted around the axis so as not to be rotatable.

Although not specifically shown, the guide rod 82 is rotatably supported by a bearing means on the main body side.

On the other hand, the output shaft 70a of the step motor 70 is coupled with one end of a threaded shaft 75 having threads 74.76 cut in opposite directions with respect to the midpoint, and these threaded grooves 74.7.
6 is screwed into screw holes (not shown) formed in the bases 78a, 80a of the arms 78.80 provided for sliding the shutters 66, 68. Although not specifically shown, the screw shaft 75 is rotatably supported by a bearing provided on the main body side. The arms 78.80 have their distal ends 78b, 80b (see FIG. 10) inserted into the engagement grooves (not shown) formed in the guide tubes 66a, 68a of the shutters 66.68.
The guide rod 82 is displaceable in the axial direction, and is engaged with the guide rod 82 so as to allow rotation around the axis (without rotating itself). Since thread grooves 74 and 76 opposite to each other are cut in the threaded shaft 75, the arms 78 and 80 are displaced in opposite directions as the output shaft 70a of the step motor 70 rotates. Therefore, the tip 7811 of the arm 78.80
, 80b, which are respectively fixed to the guide tubes 66a and 68a, are also guided by the guide rod 82 and displaced in opposite directions, so that the shutters 66 are aligned with respect to the center of the photosensitive drum 34. Another shutter 68 blocks light on the other side with respect to the center of the photosensitive drum 34.

In addition, in FIGS. 9 and 10, two shutters 66
．． The positions of the screws 7W74 and the photosensitive drum 34 are adjusted by one step motor 70 in relation to each other, but the screws 7W74 are attached to screw sleeves (separate from the screw shaft 75).
Not shown. ) and coupled to the output shaft of the shutter (not shown) so that the shutters 66, 68 can be adjusted independently of each other. In this way, the exposure area of the photosensitive drum 34 can be set arbitrarily.

As mentioned above, the guide rod 82 that guides the shutters 66, 68 is coupled at one end to the center of the pivot member 84. A spring 86 and a plunger 72a of the solenoid 72 are connected to both Ial of the rotating member 84, respectively. The rotating member 84 is normally urged in the direction indicated by arrow A by the spring force of the spring 86, and is in the position indicated by (c) in FIG. In this state,
The shutters 66 and 68 have respective distal ends located near the outer peripheral surface of the photosensitive drum 34, and project light onto the photosensitive drum 34. On the other hand, the rotating member 84 is connected to the solenoid 7.
When 2 is energized, it rotates in the direction shown by arrow A to the position shown by (d). As a result, the guide rod 82
At the same time, the shutter rotates from 66°68° to the position shown in (E) to (E).
-The projected light will be partially blocked.

On the other hand, together with the shutter unit 60, the photosensitive drum 3
As shown in FIGS. 1t (a) and (b), the light emitter array 62 arranged on the outer periphery of the photosensitive drum 4 emits light emitting elements 63 such as light emitting diodes over a length approximately equal to the length of the photosensitive drum 34. They are arranged in a line. The light emitting element array 62 has a light emitting surface of its light emitting elements 63 attached to the photosensitive drum 34.
is placed facing the photosensitive surface. The light-emitting element 63 is turned on and off by the light-emitting array driving device 13 in response to a control signal from the main body CPU 8 of the control means 3 (see FIG. 1).

Returning to FIG. 3 again, a paper feed section 58 is provided below the photosensitive drum 34 for supplying copy paper to the transfer charger 50. Further, on the downstream side of the transfer charger 50 in the copy paper conveying direction, there is a fixing device 59 for fixing the transferred visible image on the copy paper, and at the lower front end of the operation panel 24, the fixing device 59 discharges the fixed copy paper. Paper discharge ports 61 are provided respectively.

The timing of supplying copy paper to the transfer charger 50 is controlled by a timing roller 64.

[Operation] Next, the configuration described above and the operation of the doubling will be explained.

Image trimming will be described as an example of image editing.

When the image shown in FIG. 12(a) is projected on the screen 22 of the reader printer main body 21 in FIG. 2 during the league,
At point Ben 31, point I, II, III,
Press IV, specify the desired copy range, and then specify the desired image processing type (in this case, "trimming").Then point 1.II.

The (x, y) coordinates and image processing mode corresponding to IIl and IV are input to the editor CPU 7 as described above. Note that input for image editing is possible only during the league, and input is disabled during print operation due to a control signal from the main body CPU 8.

The print polarity signal is sent to the main body CPU from the selector switch 9.
The control method for image editing differs depending on whether the polarity of the microfilm is N-P or P-P.

At the time of NP, image editing is performed by controlling the developing bias in the shutter unit 60 arranged on the photosensitive drum 34 and the developing device 11, as shown in FIG.

To explain this using FIG. 12(a) as an example, point 1. II, III, Iv coordinates (X,, Yυ, (x,, y,), (x,, y,),
(X t, Y J and the image processing mode (trimming in this case) are transferred from the editor CPU 7 to the main body CPU 8. Based on the above data, the main body CPU 8 calculates the amount of movement of the shutter 66, 68 in the X-axis direction, the The ON/OFF timing of the developing bias in the direction is calculated.

In the control in the X-axis direction, when the main body CPU 8 detects that a print switch (not shown) is turned on, it drives the step motor 70 so that the shutters 66 and 68 are located at positions corresponding to XI and X2. In addition, the solenoid 72 turns on the image leading edge detection sensor (not shown), that is, starts exposure. It turns on when it passes through the position and reaches the (su) position.

When the solenoid 72 is turned on, only the area between X, , Form an image R section. In the control in the y direction, since the developing device 12 is arranged with respect to the shutter unit 60 as shown in FIG. 13, the main body CP

On the other hand, during P-P, image editing is performed by controlling the individual light emitting elements 63 of the light emitting array 62 arranged on the photosensitive drum 34, as shown in FIG. 11(a).

Taking FIG. 12(a) as an example, at the start of the print operation, data necessary for image editing is transferred from the editor CPU 7 to the main body CPU 8, as in the case of NP. Main body C
Based on this, the PU8 turns each light emitting element 63 on and off.
Calculate FF timing. As shown in FIG. 14, all of the light emitting elements 63 are turned on at the same time as the print switch is turned on. And xl, xtf! Since the developing device I2 is arranged in a relationship as shown in FIG. 13 with respect to the light emitting element array 63, the light emitting element 63 of No.

Lighting of the light emitting element 63 erases the photosensitive drum 34 to form a non-image area, and an electrostatic latent image is formed on the photosensitive drum 34 only in the portion where the light emitting element 63 is turned off. P
The timing of the developing bias during -P is the same as in the normal copy mode shown in the upper part of FIG. 14, and the shutter solenoid 72 is OFF during the printing operation.

In the above manner, a copy image as shown in FIG. 12(b) can be obtained from P-P.

In the above, FfiJR trimming is taken as an example when NP,
Although the control method during P-P has been described, the movement of the image can be achieved by changing the ON timing of the timing roller 64 in FIG. If the distance to be moved is defined as the distance, the image can be moved by turning ON with a delay of 1/v from the normal ON timing. Furthermore, in the present invention, decoding such as "trimming + moving" is also possible.

As is clear from the detailed description above, according to the present invention, a transparent sheet-like partial copy information input means is attached to the screen, and partial copying is performed while viewing the image projected on the screen. You can input the necessary image information by pressing the information input means with a point pen, etc., so you can use a pen, etc. to edit text or figures printed or written on IT paper into the desired form. Image editing can be performed in the same manner as in the previous version, which greatly simplifies manual image editing, and allows for a wide variety of image editing.

Further, according to the present invention, image editing can be performed on negative and positive microfilms.
