Description

Detailed Description of the Invention The present invention is a recording method in which a recording sheet such as a film or photosensitive paper on which an image has been photographed is temporarily stored in a storage section, and the recording sheet in the storage section is sent to a developing section at an arbitrary time for development processing. It is related to the device.

Conventionally, this type of recording device is equipped with an operation switch that commands the start of development, and when the operation switch is operated, the recording sheet in the storage section is started to be fed to the developing section, and the recording sheet is cut to be cut into any desired length. A recording sheet (hereinafter, the recording sheet cut and separated is referred to as a "strip sheet" or "strip film") is obtained. This strip sheet records an image of a unit of original document with information content, and is used by reading it with a microfilm reader or the like.

In such a recording device, if you carelessly operate the operation switch incorrectly, the recording sheet will be cut at the wrong place, resulting in one unit of image being recorded on separate strip sheets. Therefore, the strip sheets had to be connected after the development process, which was very troublesome.

The present invention solves the above problems and provides a recording device that prevents the accident of accidentally cutting a recording sheet.

Hereinafter, the present invention will be explained with reference to specific examples shown in the drawings.

FIG. 1 shows a processor camera to which the present invention is applied, including a photographing section A that exposes an image of a document onto a film, and a developing section B that develops the film sent from the photographing section A.
It is equipped with

Sheet-like originals 1 to be photographed are stacked and stored on an original mounting table 464, and paper feed rollers 2 rotate in the directions of the arrows.
The documents are sent out one by one by the separation roller 3. The document sent out from the document table is sent to the exposure section 5 at a constant speed by a pair of feed rollers 4, and after passing through the exposure section, it is discharged to the document receiving tray 8 by the discharge roller 7. The upper roller of the pair of feed rollers 4 is displaced upward when a document is fed 9 between the pair of rollers 4, and the document detection switch 6 is activated by the upward displacement of the upper roller. A document detection signal is generated.

The original 1 is sent out one after another by the roller 2-3 at a constant interval of 91 sheets, and as it passes through the exposure section 5, it is photographed on a microfilm F.

The microfilm F is wound around a supply reel 10 that is removably disposed in the supply chamber 9, passes through a guide roller 11, passes between a capstan roller 12 and a pinch roller 13, and is sent to a storage chamber 15. . Capstan roller 12
is coupled to a motor, and the motor is driven and rotated by the document detection signal output from the document detection switch 6.
Microfilm F is fed in synchronization with the feeding of the original.

The microfilm F fed by the capstan roller 12 is stored in a loop in the storage chamber 15. The image of the document that is fed through the exposure section 5 at a constant speed is captured by the imaging lens 1.
6, the microfilm being fed by the capstan roller 12 is exposed. A shutter 17 is driven by a document detection signal. A discharge roller 18 coupled to a motor is disposed near the exit of the storage chamber 15, and the microfilm F stored in the storage chamber is sent to the developing section B by the discharge roller 18.

Reference numeral 22 denotes a leftover detector for detecting the remaining amount of film wound on the supply reel l○, which consists of a known detector for detecting film latitude, and generates an alarm signal when the remaining amount of film reaches a set value. This alarm signal activates the hakama alarm,
To clearly indicate to the user that the amount of film is running low.

25 discharging rollers 18 are arranged near each other,
A film guide 31 is disposed along a meandering film feeding path from a storage chamber 15 to a feeding tank 28, a drying section 29, and a winding chamber 30 from a developer tank 26 to a drying section 29 by a discharge roller 18. has been done.

Exposure section film F sent from photographing section A to developing section B
The film is guided by a film guide 31, passes through a developing solution, a first fixing solution, and a wooden barrel solution, passes through air heated by a heater 32 in a drying section 29, and then passes through a capstan roller connected to a motor. A fan for blowing heated air onto the film through the winding loop 35 of the winding unit 30 through between 33 and the pinch roller 34; 37 is a film detector that detects the presence or absence of film; 3
It is located near the entrance of 0.

Film feeding rollers (not shown) are arranged in each M26, 27, 28 and the drying section 29, and the film F is automatically fed through the various types and the drying section by these feeding rollers. ing.

In the developer tank 26, a heater that heats the developer, a solution temperature detector consisting of a thermistor*star that controls the heater, and a solution stirrer with a fan for stirring the solution are arranged. The heater is energized until a predetermined temperature is detected, and when a predetermined temperature is detected, the heater is de-energized to maintain the developing section at a desired temperature.

The liquid agitator operates in conjunction with the film feeding mechanism of the developing section B, and operates to stir the developer when the film is being fed to the developing section, and when the film feeding is stopped. 8 is inoperative and is configured so as not to stir the developer.

The winding unit 30 also includes a film guide plate, a winder that automatically winds the leading edge of the film around the winding reel 35, and a winder that detects when the film is wound around the winding reel 35. An attached detector is installed.

The winder and the winding detector are, for example, disclosed in Japanese Utility Model Application No. 55-178.
Since this is known from Japanese Patent No. 139, its explanation will be omitted.

FIG. 2 shows a control circuit of the camera, and 50 is a development start command switch, which is a self-recovery type switch. 51 is a timer that operates for a preset time t when the switch 50 is operated; 52 is an inverter; 53 is an AND gate; 54 is a discharge roller 1M3 driving circuit that drives the motor that rotates the discharge roller 18; is a cutter drive circuit that drives the cutter 25.

FIG. 3 shows signal waveforms at various parts of the control circuit shown in FIG. 2.

Next, the operation of the above camera will be explained. Initially, the leading edge of the film is held between the discharge rollers 18, and the discharge rollers 18 stop rotating. In this state,
When the originals 1 are fed one after another to the exposure unit 5, the film on which the originals have been photographed is fed to the storage chamber 15 by the capstan roller 12 and stored in a loop in the storage chamber 15, increasing the film stock in the room. .

Now, a case will be described in which the development start switch 50 is operated by mistake while photographing a unit of document with related information content.

If the switch 50 is operated incorrectly, a pulse signal a1 with a short time width (a
waveform) appears.

This pulse 1d number a1 activates the timer 51, and the timer 51 outputs a signal b], (waveform shown in Figure 3). This signal b1 is output for a time t set by a timer. This signal b1 is inverted by the inverter 52 and input to the first input terminal O of the AND gate 53. On the other hand, the output No. 18 of the switch 50 is input to the second input terminal of the AND gate 53, but when the high level pulse signal a1 is sent to the second input terminal, the output of the first input terminal is Since the input signal is at a low level, the AND gate 53 does not open, and as a result, the discharge roller drive circuit 54 and the cutter drive circuit 55 do not operate, the discharge row 218 does not rotate, and the cutter 25 in the housing does not operate. . Therefore, the film is not sent to the developing section and is not cut by the cutter, and malfunctions can be prevented even if the switch is operated carelessly.

Next, if you want to develop the photographed film after completing the photographing work for one unit of original, operate the development start switch 50 continuously for a time longer than the time t set by the timer 51 (the switch 50 is on for more than an hour). When the switch 50 is operated in a predetermined manner for a long time, a pulse signal a2(
Figure 3 a waveform) appears.

This pulse signal a2 activates the timer 51, and the timer 51 outputs a signal b1 having a set time width t.

After this, when the timer 51 becomes inactive, a high level signal el is input to the first input terminal a of the AND gate 53, and at this time, a high level pulse signal a2 is input to the second input terminal of the AND gate 53. is input, the AND gate 53 opens, and the discharge roller drive circuit 54 is activated by the high level signal dl (waveform d in FIG. 3) output from the AND gate 53. The operation of the discharge roller drive circuit 54 drives the motor that rotates the discharge roller 18, the discharge roller 18 starts rotating, and the film in the storage chamber 15 is sent to the developing section B. The film feeding roller of the developing section B is rotated in advance, and the film sent to the developing section B is guided by the film guide 31, sent to the take-up reel 35, and wound up on the take-up reel 35.

When the film capacity in the storage chamber 15 decreases and the storage amount reaches a minimum, the rotation of the discharge loaf 18 draws the film from the supply reel 10 into the storage chamber and the final exposed area on the film matches the cutting position of the cutter 25. H when passing
A stop signal is issued from the 1lJ control section. This stop signal is sent to the input terminal θ of the ejection roller drive circuit 54, thereby disabling the ejection roller drive circuit 54 and disabling the ejection roller 18.
stops rotating. Simultaneously with or immediately after generation of the stop signal, the cutter drive circuit 55 is activated to drive the cutter 25 and cut the film. Therefore, the film is cut at the trailing end of the final exposure area, and one unit of original document is completely recorded on the separated strip film, and this strip film is completely wound onto the take-up reel 35.

As described above, if the operation switch 50 is not operated for a predetermined period of time, the drive of the cutter is prohibited, and if the operation switch 50 is operated for a predetermined period of time or more, the prohibition of drive of the cutter is canceled and the cutter is driven at an appropriate timing to cut the film. The film is cut only when the operation switch is operated in the prescribed direction, and the film will not be cut accidentally if the operation switch is operated incorrectly, so that the work can be carried out with peace of mind.

In the above embodiment, the cutter is provided near the outlet of the storage chamber, but the cutter may be provided between the supply reel and the storage chamber. When the cutter is installed between the supply IJ-hole and the storage chamber, the timing at which the cutter is driven after operating the operation switch as prescribed is different from that of the above embodiment. When the manual operation switch is operated continuously for a predetermined period of time, an indicator may be turned on to clearly indicate that the switch has been operated in a predetermined manner.
