Abstract

PURPOSE:To simplify the constitution of the title processor by providing a line-like dot printing printer for recording frame numbers on the rear face of a photosensitive sheet synchronously with the carrying of the photosensitive sheet based upon a pair of processor side carrying rolls. CONSTITUTION:The photosensitive material 15 on which an image on a film 13 is printing exposed is carried to the process side by the pair of printer side carrying rolls. At that time, the line-like dot printing printer 45 is driven synchronously with the carrying of the photosensitive sheet 15 based upon the pair of carrying rolls 32 and frame numbers are recorded like dots in each line. Since the frame numbers can be recorded on the rear face of the sheet 15 by the printer 45 and the driving of the printer 45 is controlled synchronously with the carrying of the rollers 32, a device or the like for moving the printer 45 can be omitted. Consequently, the constitution of the device can be simplified.

[Problem to be solved by the invention]

Therefore, when performing reprint processing, it is necessary to compare the negative film with the photograph desired for reprinting, which is time consuming, and there is a problem in that specifying frames at the time of reprinting is troublesome.

This problem can be solved by printing the frame number printed on the negative film on the back of the printed photograph.

However, simply frames recorded on film.

When attempting to read number information and record it on a photosensitive material that has been printed and exposed, it is necessary to attach a frame number recording device to the printer section, which creates a new problem of complicating the device configuration. Therefore, it is desired that the device configuration be simplified, and furthermore, it is desired that the printing position of the frame number can be easily specified.

The present invention has been made to solve the above-mentioned problems, and it is possible to record the frame numbers of the exposed film on the corresponding exposed photosensitive material with a simple structure, and furthermore, the printing position of the frame number can be changed. The object of the present invention is to provide a photo printing/processing device that allows easy specification.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides printer means for printing and exposing a film image onto a strip-shaped photosensitive material, and cutting the exposed strip-shaped photosensitive material into one frame sheet. a pair of processor-side conveying rollers that convey the cut photosensitive sheet to the processor; and a line-shaped roller that is arranged between the cutter and the processor and that prints the frame number of the film on the back side of the photosensitive sheet that is being conveyed. The apparatus is provided with a dot printing printer, and a control means for operating the dot printing printer in synchronization with the feeding of the photosensitive sheet when a certain period of time has elapsed since the photosensitive sheet was cut.

(Operation) The photosensitive material on which the image on the film has been printed and exposed is conveyed to the process side by a pair of conveyor rollers on the printer side. At this time, based on the frame number information of the film, the photosensitive material is synchronized with the feeding of the photosensitive sheet by the pair of conveyor rollers. The line-shaped dot printing printer is activated and records the frame number one line at a time in the form of a dot.In this way, the frame number can be recorded on the back side of the photosensitive sheet using the one-line dot printing printer.
The configuration of the frame number recording device can be simplified. Moreover, since the L-line dot printing printer is driven and controlled in synchronization with the feeding of the printer-side conveying roller pair,
The device configuration can be further simplified by eliminating the need for a device for moving the printer. Furthermore, since the dot printing printer operates when a certain period of time has elapsed after cutting the photosensitive sheet, frame numbers can always be printed at fixed positions on the photosensitive sheet.

Therefore, the frame positions of the negative film 13 in the film holder 12 and the scenes of the frames can be observed.

The frame positions and scenes can be observed using a video camera and a monitor CRT in addition to the screen.

The photographic paper 15 is conveyed by one frame from the photographic paper roll 33 by a guide roller 30 and a pair of printer-side conveyance rollers 32 driven by a pulse motor 31, and is positioned on a print stand 34. The rotation of the pulse motor 31 is controlled by the controller 16 via the driver 31A. Print stand 3
4 is configured to vacuum-adsorb the photographic paper 15 in order to ensure the flatness of the photographic paper 15, and the print stand 3
Above 4 is ゛? A screen 35 is arranged.

A cutter 36 is disposed on the photographic paper discharge side of the print stand 34 for cutting the printed and exposed photographic paper 15 into one frame of sheet-like photographic paper 15A after it has been conveyed for one frame. This cutter 36 is driven by a command from the controller 16 via a cutter drive section 37.

The sheet-shaped photographic paper 15A cut frame by frame by the cutter 36 is sent to a processor part 39 by two pairs of process-side transport rollers 38 arranged at a predetermined interval.

The lower conveyance roller 40 of this conveyance roller pair 38 is rotated by a conveyance system pulse motor 41 on the processor part 39 side. In addition, the upper conveyance roller 42 of the conveyance roller
is equipped with a solenoid 43 for releasing the pressure contact with the lower conveyance roller 40. This solenoid 43 is drive-controlled by the controller 16, and is activated so as to release the pressure bonding of the conveying roller pair 38 when cutting and conveying the exposed print 15 by the printer side conveying roller pair 32 for cutting. 43 is energized to prevent the sheet-like photographic paper 15A from being conveyed to the processor part 39.

Between the 2Mi transport roller pair 38 is a line-shaped dot printing printer 45 for printing the frame number of the negative film 13 on the back side of the exposed sheet-like photographic paper 15A.
is located. As shown in FIG. 2, the dot printing printer 45 has nine dot bins 4 so as to be able to record, for example, 9×5 dots of numbers, alphabetic characters, etc.
It is equipped with a printer head 48 in which 7 are arranged in one row. Note that the reference numeral 49 in the figure indicates an ink ribbon. This dot printing printer 45 is controlled by the controller 16 via a driver 46, and is configured to print the number of the printed and exposed code 7 on the back side of the corresponding photographic paper 15A based on the data from the frame number reading sensor 14. ing.

The controller 16 is configured to control each driving section, driver, etc. at the timing shown in FIG.

The operation of this embodiment will be explained below with reference to FIGS. 1 to 3. First, the negative film 13 is inserted into the film holder 12, the inserted negative film 13 is observed through the screen 29, and a predetermined frame is set at the exposure position. At this time, the filter turret 19 is at the white position such that the hole is located on the printing optical path.

In this way, after monitoring the negative film 13 in the film holder 12, press the start key for exposure.
(not shown) is pressed, the controller 16 rotates the motor 22, sequentially inserts each filter of the filter turret 19 onto the printing optical path, measures the light for each color via the scanner 24, and processes the characteristic value calculation section. 27 to obtain characteristic values for each color. Then, based on these characteristic values, the exposure amount for sequential exposure of three color planes is calculated.

Next, the controller 16 sequentially rotates the filter turret 19 by a predetermined angle based on this calculation result, and
The shutter 21 is retracted from the printing optical path via the shutter drive unit 20, and three-color planes are sequentially exposed using green light, red light, and blue light. After this exposure is completed, the filter turret 19 is positioned at a black position where it blocks the printing light.

Thereafter, the controller 16 lifts the upper conveyance roller 42 of the process side conveyance roller pair 3 upward via the solenoid 43, and releases the pressure contact between the conveyance roller pair 38. After this release is completed, the pulse motor 31 is rotated via the driver 31A, and the printer-side transport roller pair 32
The photographic paper 15 is advanced one frame at a time. After this frame feeding is completed, the controller 16 operates the cutter 36 via the cutter drive unit 37 to cut the strip-shaped photographic paper 15 into one frame of sheet-like photographic paper 15A.

After this cutting, the upper conveyance roller 4 is
2 is released, the pair of conveying rollers 38 is placed in a pressed state, and one frame of the exposed sheet-like print 15A sandwiched between the pair of conveying rollers 38 is conveyed to the process side.

During this conveyance, as shown in FIG.
Line-shaped dot printing printer 45 synchronizes with the feeding of
As a result, the frame number from the frame number reading sensor 14 is printed on the back side of the photographic paper 15A. This frame number can be printed at a fixed position on the back side of the photographic paper 15. Specifically, a certain period of time T from the time of disconnection.
, after which printing starts.

Further, after the belt-shaped photographic paper 15 is conveyed by one frame by the printer-side conveyance roller pair 32 and cut into one frame of sheet-shaped photographic paper 15A by the cutter 36, the controller 1
6, the filter turret 19 is rotated by a predetermined angle, and the hole is placed in the white position on the printing optical path, thereby making it possible to monitor the exposure of the next frame. As a result, the monitor screen 28 is used to confirm the setting of the next exposure/print 1 frame and the scene.
By pressing the start key, the above-described printing exposure is repeated.

The controller 16 uses a timer circuit to count the elapsed time T from the time of cutting, and does not energize the crimping solenoid 43 until this count value reaches the set value T, even after the printing exposure is completed. There is no frame-by-frame forwarding. Here, the set value Ts of the timer circuit is determined as follows, taking into consideration the line speed (2) which is the processing speed of the processor part 39 and the photographic paper conveyance speed V2 on the printer side.

Ts - ((Lo+L+)/L I LO/VZ 're Note that L indicates the length of the sheet-like photographic paper 15A for 137 minutes, and L represents the length of the sheet-like photographic paper 15A for the preceding one frame and the following sheet-like photographic paper 15A. It shows the separation distance from the sheet-like photographic paper 15A for one frame. Also, Tc is the time required for cutting. Therefore, before the time T set by the timer circuit has elapsed, the prints for a new frame cannot be sent to Gion. Therefore, the leading edge of the subsequent exposed printing paper 15 does not touch the rear end of the previously exposed sheet-like printing paper 15A that was cut earlier, which prevents jamming and overlapping of the exposed photographic paper. It can be prevented.

In the above embodiment, the printing exposure is performed by additive color sequential exposure, but the present invention is not limited to this, and exposure may be performed by subtractive color method.

[Effects of the Invention] As explained above, according to the present invention, a line-shaped dot printing printer is provided that records frame numbers on the back side of a photosensitive sheet in synchronization with the feeding of the photosensitive sheet by a pair of processor-side conveying rollers. The frame number can be recorded on the back side of the photosensitive sheet by a one-line dot printing printer with a simple configuration, and the configuration of the frame number recording device can be simplified. Furthermore, since the dot printing printer for one line is driven and controlled in synchronization with the feeding of the pair of printer-side conveying rollers, a device for moving the printer or the like is not required, and the device configuration can be further simplified.

Furthermore, since the dot printing printer is activated in synchronization with the feeding of the photosensitive sheet when a certain period of time has elapsed after cutting the photosensitive sheet, the frame number can always be printed at a fixed position on the photosensitive sheet.
