Description

  The present invention relates to a battery removing method for removing a power supply battery for recycling from a used circuit board, and a power supply battery for collecting and recycling a film unit with a lens (hereinafter referred to as “film unit”). The present invention relates to a disassembling method and apparatus to be removed.

  The film unit includes a main body base portion in which a film storage chamber is formed on one side of the exposure opening and a cartridge loading chamber is formed on the other side. In the main body base, an exposure unit in which a photographing lens and a shutter mechanism are integrated is detachably assembled in front of the exposure opening, and these are covered with front and rear covers from the front and rear. In the strobe device, the strobe board is detachably mounted between the exposure unit and the film storage chamber, and the power supply battery is laid sideways so that it protrudes from the bottom of the strobe board to the bottom of the exposure unit. The strobe light emitting unit is exposed from an opening provided in the front cover. In the strobe device, a positive battery contact piece and a negative battery contact piece are soldered to a strobe board on which a main capacitor and a light emitting unit are mounted, and a cylindrical power battery (AA battery) is interposed between the contact pieces. Is attached.

  The battery contact piece has a function of electrically connecting the power source battery and a function of projecting and holding the power supply battery on the strobe board, whereas one plus side contact piece is a short piece extending directly under the strobe board. The minus side contact piece is provided at the tip of an extension extending long from the strobe substrate toward the exposure unit so as to be opposed to the plus side contact piece. The distance between the contact pieces corresponds to the length of the power battery in the longitudinal direction. Moreover, in order to maintain contact firmly, the notch or opening which the protrusion part of a power supply battery enters is formed in the plus side contact piece.

  The film unit collects and disassembles after use, removes the parts, and reuses the removed parts as they are, or recycles them by remolding them after remolding them. The power battery is automatically taken out with the strobe device attached to the base of the main body by the battery removing device after the front cover is removed (Patent Document 1).

  Such a disassembly device for taking out the power battery has a robot hand integrally having a release claw and a take-out plate. After the release claw and the take-out plate are moved together to the take-out position, the release claw is moved to the plus side. Insert between the contact piece and the battery protrusion to release the positive contact between the opening and the battery battery protrusion, and then rotate the take-out plate to move the power battery body upward. It is pushed out and pushed out.

  Further, there is a type in which the film unit is covered with a part of the rear cover (battery cover) in the direction of taking out the power battery. In this case, it is known to use a device for taking out the power battery after spreading the battery cover outward before taking out the power battery (Patent Document 2).

  The power supply battery take-out device described in Patent Document 2 includes a holding unit that integrally has a battery floating bar and an electromagnet. The holding unit sequentially moves to three positions including a standby position, a take-out position, and a discharge position. The movement from the standby position to the take-out position is lowered in the vertical direction. Before reaching the take-out position, the battery cover is gradually spread outward at the lower part of the electromagnet. Then, when moved to the take-out position, the receiving portion of the electromagnet that receives the power battery is located in the vicinity of the power battery, and the tip of the battery floating rod is located between the strobe board and the power battery with the positive side contacted The power supply battery is pushed out toward the electromagnet at the slope provided at the tip after entering the position. As a result, the power supply battery is magnetically attached to the electromagnet. Thereafter, the holding unit moves to the discharge position and releases the magnetism of the electromagnet, whereby the holding of the power supply battery in the holding unit can be released.

  By the way, the extension part having the minus side contact piece is arranged along the longitudinal direction of the body part of the power battery, and is covered with the front cover. In a power battery, generally, the inside of an insulator covering the body is a plus electrode. For this reason, for example, if a strong force is applied to a part of the front cover from the outside and a part of the extension part is pushed toward the battery, the part of the extension part may break the outer shell of the power battery. . If this happens, the extension that is the negative terminal and the inside of the outer shell of the power battery that is the positive terminal may be short-circuited, and if it is short-circuited, a large current flows through the power battery and the power battery generates heat. It becomes. Therefore, it is desired to make a strobe board with the extension-side contact piece as a plus terminal and the opposite short contact piece as a minus-side contact piece, and to incorporate a power battery with the polarity direction reversed.

  The protrusion, which is the positive electrode of the power battery, is difficult to engage with the mating positive side contact piece. For this reason, as described above, the positive side contact piece is provided with an opening and a notch for engaging the protrusion. However, when the power battery is removed, the positive side engaging portion is stubbornly engaged. Therefore, the power source battery can be rotated by pushing the portion of the battery close to the positive side engaging portion. It is known that it will be pushed straight out. By pushing straight out in this way, it can be held securely by the holding part, and the orientation of the polarity is aligned when checking the capacity of the power battery after removing the power battery by maintaining the same posture. Save time and effort.

JP-A-6-175295 JP-A-11-212219

  However, in the case of a strobe device in which the polarity of the power supply battery is reversed, pressing the same part as described above pushes the part close to the negative side contact piece, so that the battery is not pushed out straight.

  Further, when considering pushing out the portion near the plus side contact piece and the plus side contact piece, the extension portion becomes an obstacle. This is because there is a gap for inserting a jig, such as a battery floating rod or an extrusion rod, on the side of the body of the power battery, that is, the space between the power battery body and the exposure unit when the film unit is viewed from the front. This is because it is hidden by the extension when the front cover is removed.

  Therefore, a plan to push out the power supply battery together with the extension is conceivable. However, in this plan, there is a problem in that it takes time to repair or replace the extension when reusing the strobe board. In addition, with the chuck in which the battery floating bar or push bar and the holding member are integrally attached, the battery floating bar or push bar cannot be inserted into the extension or the side thereof with high accuracy.

  Furthermore, there is a plan to take out the power supply battery together with the strobe board, but in this proposal, the strobe board is handled with the power supply battery attached, and this causes both terminals of the main capacitor where charges are accumulated to be transported, for example. If the metal part is touched and short-circuited, the circuit of the main capacitor or strobe board may be electrically damaged. Moreover, even if the main capacitor is discharged with the power supply battery attached, the stroboscopic charge is started by touching something, and there is a possibility that the main capacitor is charged again.

  Therefore, a first object of the present invention is to provide a battery removal method devised so that a cylindrical battery is taken out straight from a circuit board. It is a second object of the present invention to provide a method and an apparatus for disassembling a lens-fitted photo film unit in which a power supply battery can be taken out without damaging an extension portion having a plus side piece and a strobe circuit.

  In order to achieve the above object, according to the present invention, the pushing member is inserted into the side of the body of the power battery from one direction intersecting the longitudinal direction of the power battery, and the first claw provided on the pushing member is added when the pushing member is inserted. A direction in which the power supply battery is perpendicular to the one direction by pushing the barrel near the side contact piece and pushing the barrel near the negative side contact piece with the second claw provided on the push-out member later than the first claw. Extruded toward the

  In addition, it is good also as a battery removal apparatus instead of a battery removal method. As a preferable configuration in this case, the first claw that pushes the barrel portion closer to the plus side contact when inserted into the pushing member that is inserted to the side of the barrel portion of the power battery from one direction intersecting the longitudinal direction of the power battery. And a second claw that pushes the body portion closer to the negative side contact piece behind the first claw, and pushes the power supply battery in a direction orthogonal to the one direction.

  Further, in the invention of the method or apparatus for disassembling the lens-fitted photo film unit, any one of the plurality of outer covers is removed by the battery exposing means, or a part of the other cover is removed after removing any one of the covers. And exposing one surface of the four surfaces around the body of the cylindrical power battery and the other surface connected to the one surface, and then exposing the one and other surfaces, and then by holding member moving means, A holding member having a receiving part for holding the body part of the power battery by magnetic force is moved to a holding position in the space on the one surface and away from the power battery in a direction in which the receiving part faces the body part, Next, after the holding member has moved to the holding position, the pushing member moving means is provided on the other electrode side contact piece which is a plus side electrode from a direction perpendicular to the other surface. Total Inserted into the body of the power battery through a notch provided in a part of the part, pushes the power battery toward the receiving part, and then a holding member holding the power battery by the control means After moving from the holding position to the discharging position for discharging the taken-out power supply battery, the holding member moving means and the pushing member moving means are individually and synchronously driven so that the pushing member moves to a standby position different from the discharging position. It is what you do.

  The pushing member may be only a claw that pushes the body part closer to the plus side contact through the notch, or in addition to the nail, a second claw that pushes the body part near the minus side contact piece is provided. Also good.

  In the battery take-out method of the present invention, the push-out member for pushing out the power supply battery is provided with the second claw for pushing the barrel portion closer to the minus side contact piece in addition to the first claw for pushing the barrel portion closer to the plus side contact piece. The power battery can be pushed straight out of the circuit board.

  In the disassembling method or apparatus for a lens-fitted photo film unit according to the present invention, a notch is provided in an extension having a plus side contact piece, and a power source battery is pushed out by inserting an extruding member through the notch. The battery can be removed without damaging the extension. In addition, since the pushing member and the holding member are configured to be individually movable, as described in the prior art, the gap for inserting the pushing member and the pushing member are compared with the chuck having the pushing member and the holding member integrally. There is no restriction on the movement, and the degree of freedom for taking out the power battery increases.

  As shown in FIG. 1, the film unit 2 is composed of a unit main body 3 having a photographing mechanism and an outer case 4 that accommodates the unit main body 3, and photography is performed with the outer case 4 attached. The outer case 4 is for making the appearance of the film unit 2 beautiful, and a paper box or a plastic sheet on which the outer surface is printed is used.

The shutter cover 20 is formed with a fixed aperture opening and a lens receiving portion protruding so as to surround the aperture opening. The taking lens 5 is inserted into the lens receiving portion, and the taking lens 5 is held by attaching the lens holder 21 to the lens receiving portion. Part of the lens holder 21 and the photographing lens 5 is exposed from a photographing window 22 provided on the front cover 14.

  The main body base 16 has, on both sides of the aperture 19, a cartridge chamber 24 in which the cartridge 23 is loaded, and a film storage chamber 26 in which the unexposed photographic film 25 drawn from the cartridge 23 is stored in a roll shape. It is integrally formed. The back surface side of the main body base portion 16 is opened, and the cartridge 23 and the photographic film 25 are stored in a light-tight manner with the rear cover 15 attached thereto. On the cartridge chamber 24, a winding knob 9 that engages with the spool 23a of the cartridge 23 is detachably provided. A part of the winding knob 9 is exposed from an opening 27 provided in the rear cover 15. The photographic film 25 is wound up from the film storage chamber 26 toward the cartridge chamber 24 for each photographing by performing a winding operation using a part of the exposure.

  The transfer of the photographic film by winding the film is transmitted to the film winding stop mechanism, the shutter charge mechanism, the film count mechanism, etc. via the sprocket provided in the exposure unit 18, and the photographic film 25 is transferred by the length of one frame. The film winding mechanism locks the rotation of the winding knob 9 and the sprocket. During this time, the shutter mechanism is shutter charged, and the film count mechanism advances the number display board by one step. In response to the shutter release, the shutter mechanism moves the shutter blades back and forth once to perform exposure. Further, the film winding mechanism releases the lock after the exposure is completed. This allows the next film winding operation.

  The bottoms of the cartridge chamber 24 and the film storage chamber 26 are open and are closed by bottom lids 28 and 29 formed on the rear cover 15. The bottom lid 28 of the cartridge chamber 24 serves as a lid when the cartridge 23 is taken out at the developing station. The bottom lids 28 and 29 have a pull-top type structure in which a portion between the bottom cover 28 and the rear cover 15 is thin and can be freely opened and closed.

  The strobe unit 17 is a strobe unit in which electronic components such as a circuit element including a strobe charging circuit, a light emitting unit having a strobe light emission window 11, a sync switch, a battery contact piece, a main capacitor, and the like are attached to a strobe board 30 together. The component includes a switch lever 31 integrally provided with the strobe charging switch 10, a receiving plate 32 that guides the movement of the switch lever 31, and a power battery 33 that is detachably connected to the battery contact piece. The strobe unit 17 is detachably attached to the main body base 16 by claw coupling, and is sandwiched between the front cover 14 including the receiving plate 32 and the switch lever 31. The power battery 33 is disposed below the exposure unit 18 in a posture along the film feeding direction.

  The rear cover is integrally provided with a battery cover 34 that covers a part of the outer periphery of the power battery 33 between the above-described bottom covers 28 and 29. The battery lid 34 is a pull-top lid like the bottom lids 28 and 29, and is connected to the other surface (film unit 2) that is covered by the front cover 14 among the four surfaces around the body of the power battery 33. Cover the bottom). The switch lever 31 short-circuits the contact for starting charging the main capacitor provided on the strobe board 30 by operating the strobe charge switch.

  The front cover 14 is detachably coupled to the main body base 16 by claw coupling. The rear cover 15 is also detachably coupled to the main body base 16 by claw coupling. Such a film unit 2 is collected in a factory after use and disassembled in the factory.

  As shown in FIG. 3, the power battery 33 is attached in a posture in which it is laid down under the strobe substrate 30 at a position where the flat surface 33 a of the negative electrode does not protrude from the right end 30 a of the vertically long strobe substrate 30. In this attached state, the positive electrode protrusion 33 b of the power supply battery 33 protrudes in the longitudinal direction from the left end 30 b of the strobe substrate 30 toward the exposure unit 18.

  The battery contact piece provided on the strobe board 30 includes a minus side contact piece 35 and a plus side contact piece 36 formed of an elastic conductive material. The minus side contact piece 35 is a short piece whose one end is soldered to the minus terminal for power supply of the strobe board 30 and the other end extends directly under the strobe board. The plus side contact piece 36 has one end 37a at the strobe board. The other end 37 b of the extension 37 that is soldered to the power supply positive terminal 30 and extends long toward the exposure unit 18 is bent so as to face the minus side contact piece 35. The distance between the contact pieces 35 and 36 corresponds to the length of the power supply battery 33 in the longitudinal direction.

  In addition, the plus side contact piece 36 is formed with a pressing piece 36a that is partly cut out and bent toward the protrusion 33b in order to maintain the contact firmly. The extension part 37 is formed with a notch part 37 c with a part cut away so that a gap for inserting a jig for pushing out the power supply battery 33 is formed between the extension part 37 and the outline of the shutter cover 20 of the exposure unit 18. . Note that the power battery 33 is an AAA battery that is smaller than an AA battery, and the length of the extension 37 is shortened.

  The disassembly line of the film unit 2 will be described. As shown in FIG. 4, the used film unit 2 is first sent to an outer case removing step 41 that is a previous step of the disassembly line 40, where the outer case 4 is removed. The unit body 3 from which the outer case 4 has been removed is sent to the front cover push-in / floating inspection step 42.

  In the front cover pushing / floating inspection step 42, the unit body 3 is positioned and held with the photographing lens 5 facing upward, the four corners on the front surface of the front cover 14 are pushed with a plurality of pushing pins, and then the unit body 3 The height is measured using a photoelectric sensor, and it is determined from the data whether the front cover 14 is floating. Only those that are not floating, that is, with the front cover completely attached, are sent to the disassembly line 40.

  An index table 43 is arranged on the disassembly line 40, and each process is arranged around the index table 43.

  Steps include unit body supply step ST1, battery lid opening / bottom lid claw bending step ST2, front cover claw removal / bottom lid suction step ST3, front cover discharge step ST4, NG discharge step ST5, switch lever discharge step ST6, backing plate Discharge / battery presence inspection step ST7, bottom lid opening / main capacitor (MC) discharge (short circuit) step ST8, power supply battery discharge step ST9, MC short circuit step ST10, strobe discharge step ST11, lens holder discharge step ST12, photographing lens charge removal air blow The process includes a process ST13, a photographing lens discharge process ST14, an objective lens discharge process ST16, an NG discharge process ST18, an exposure unit discharge process ST22, a rear cover discharge process ST23, and the like. Of the process numbers shown in FIG. 4, ST15, ST17, ST19, ST20, ST21, ST24, etc. are reserved. Also, in the following, among the operations in each process, the operations substantially the same as those described in JP-A-6-175295 and JP-A-11-212219 are described in a simplified manner.

  The index table 43 has a plurality of pallets 44 arranged side by side in the circumferential direction, and intermittently rotates clockwise to convey the plurality of pallets 44 sequentially to each step. The unit main body 3 is sent to the unit main body supply step ST1, and is sequentially transferred onto the pallet 44 by a Pick & Place (P & P) device including a robot hand or the like arranged here. The pallet 44 is provided with positioning means, and the positioning means positions and holds the unit main body 3 with the photographing lens 5 facing upward. The index table 43 intermittently rotates a plurality of pallets 44 and sequentially sends the unit main body 3 to each process.

  In the battery lid opening / bottom lid claw bending step ST2, a lid opening device is arranged. In order to check the presence / absence of the cartridge 23 and the presence / absence of the power supply battery 33, this apparatus does not get in the way when the rear cover 15 and the main body base 16 are joined and separated (the work of the rear cover discharging process). In order to achieve this, the three lids of the bottom lid 28 corresponding to the cartridge chamber 24, the bottom lid 29 corresponding to the film storage chamber 26, and the battery lid 34 are opened together.

  In the front cover claw removal / bottom lid suction step ST3, a front cover disassembly device and a suction device are arranged. The front cover disassembling apparatus includes a pressing mechanism, a coupling release mechanism, and a separation mechanism. The coupling release mechanism operates the pressing mechanism to press a part of the main body base 16 exposed from the front cover 14 from above. Is operated to insert the release claw into the coupling portion from above through the opening of the front cover 14, and flex the claw of the coupling portion in the release direction to release the claw coupling. During the release, the separation mechanism holds the front cover 14 while lifting the side cover of the front cover 14 and the main body base 16 and lifts it up from the main body base 16 for separation. Since the front cover disassembly device is described in Japanese Patent Application No. 2002-178184, detailed description thereof is omitted here.

  The suction device includes a suction machine, a nozzle, and a retractable hose that connects them. Before the front cover 14 is removed from the main body base 16 by the separation mechanism, the nozzle is moved by a moving means such as a cylinder. The suction machine is set in the vicinity of the bottom cover 28 and operates while the front cover 14 is being removed, and sucks the broken pieces of the bottom cover 28 that have been damaged and dropped inside, the broken pieces of the unit main body 3 that are broken inside, and the like. .

  In the front cover discharging step ST4, a pick & place (P & P) device for removing the front cover is arranged. A chuck mechanism is provided at the tip of the robot hand of this apparatus. As shown in FIG. 5, the chuck mechanism is a pair of scooping claws 45, 46 and a moving mechanism that moves the other scooping claw (46 or 45) closer to or away from at least one scooping claw (45 or 46). 47. Using this P & P device, the front cover 14 placed on the main body base 16 is held and lifted upward, and then discharged into a collection box arranged outside the index table 43. The front cover 14 is used for reproduction.

  Further, in the front cover discharging step ST4, a removal work confirmation means 48 for confirming whether or not the removal work of the front cover 14 has been performed in response to the completion of the operation of the front cover removal device is arranged. Yes. The take-out operation confirmation means 48 is taken out based on a detection means 49 for detecting whether or not the front cover 14 is present on the main body base 16 and a signal obtained from the detection means 49 after the operation of the front cover removal device is completed. It is comprised with the judgment means 50 which judges whether work is performed correctly. As the detection means 49, a transmission type photoelectric sensor including a light projector 51 and a light receiver 52 for detecting the front cover 14 riding on the main body base 16 is used.

  When the front cover removing device has taken out the front cover 14, since the front cover 14 is not on the main body base 16, the light receiver 52 receives the light emitted from the projector 51, and accordingly, an ON signal is received from the light receiver 52. can get. The determination means 50 determines that the operation in the apparatus has been completed correctly by receiving an ON signal after the front cover removing apparatus has completed its operation. If the front cover 14 is on the main body base 16 after the operation of the front cover removing device is completed, the light received from the light projector 51 is blocked by the front cover 14, so that the light receiver 52 can receive light. The signal obtained from the device 52 becomes an OFF signal. Therefore, the determination unit 50 determines that the removal operation of the front cover 14 has failed. This information is sent to the next NG discharge process ST5.

  Instead of the transmissive photoelectric sensor, a sensor such as a reflective photoelectric sensor that detects whether the part to be taken out is in a predetermined position without contact may be used. Also, instead of detecting the predetermined position of the target part, whether the removal part is held by the rotation of transferring the removed part, with a part of the movement path of the removed part held by the chuck mechanism as the detection range It may be configured to detect whether or not. Further, the removed part is not limited to the front cover 14 and may be any other reusable part or reusable part.

  In the NG discharge process ST5, a device for taking out the work that failed in the index table 43 is arranged, and in the front cover discharge process ST4 in the previous process, the work that failed in the front cover removal work is discharged from the index table 43. In this NG discharging step ST5, information obtained from the take-out operation confirmation means 48 is sent from the previous step ST4. The take-out device operates only when the front cover take-out operation has failed after the pallet 44 has been positioned, and the unit main body 3 is moved from the pallet 44 with the front cover 14 placed on the main body base 16. Take out.

  In the switch lever discharging step ST6, the switch lever 31 is held by the chuck claws, lifted away from the main body base 16, and then discharged to the outside of the index table 43.

  In the receiving plate discharge / battery presence inspection step ST7, the holding plate 32 is held by the chuck claws and then lifted away from the main body base 16, and then discharged to the outside of the index table 43. Is detected using a metal sensor. Information on the presence / absence of the battery 33 is sent to a battery discharge step ST9 described later.

  In the bottom cover opening / MC short-circuiting step ST8, an automatic discharge device for discharging the main capacitor of the strobe substrate 30 is installed. In this apparatus, two discharge terminals connected to a discharge resistor are moved in the vertical direction by an actuator such as a cylinder, and the two discharge terminals are brought into contact with both terminals of the main capacitor exposed on the strobe substrate 30. Discharge.

  The pushing member moving mechanism 62 moves the pushing member 60 between the raised position and the lowered position. As shown in FIGS. 7 and 8, the push-out member 60 includes a pair of claw 60 a that pushes into the cutout portion 37 c of the extension portion 37 and pushes out the power battery 33, and a pair of push-out portions near the negative contact of the power battery 33. The claws 60b, 60c are integrally formed in a single line at predetermined intervals, and inclined surfaces are formed at the tips of the claws 60a-60c so as to push the power battery 33 out of the unit body 3. .

  The push-out claw 60a has a longer protruding amount than the pair of claws 60b, 60c so as to push out the power supply battery 33 earlier than the pair of claws 60b, 60c, and the thickness is reduced so as to enter the notch 37c. Yes. The pair of claws 60b and 60c are inserted into a gap between the strobe substrate 30 and the power battery 33 within a range not covered by the extension 37, and are out of the body of the power battery 33 later than the push-out claws 60a. Press the part that is close to the negative side contact piece 35.

  The holding member moving mechanism 63 moves the holding member 61 between the standby position and the approach position. The holding member 61 includes a receiving portion 61a that horizontally holds the body portion of the battery 33, and the receiving portion is an electromagnet. The receiving portion 61 a has a shape that follows the contour of the body portion of the power battery 33. The electromagnet can turn on and off the generation of magnetic force under the control of the control unit 64. The control unit 64 synchronously controls the operations of the pushing member and holding member moving mechanisms 62 and 63 and controls holding or releasing of the holding member 61. At the standby position of the holding member 61, an accumulation box 66 for arranging and collecting the taken-out power supply batteries 33 is arranged outside the index table 43, and when returning to the standby position, the generation of magnetic force is turned off and held. The discharged battery 33 is discharged to the collection box 66.

  When the pallet 44 is positioned in the battery discharging step ST9, the control unit 64 controls the holding member moving mechanism 63 to move the holding member 61 to the approach position, as shown in FIG. In this moving process, first, it moves in the horizontal direction and passes over the pushing member 60 and then descends in the vertical direction so that the receiving portion 61a faces the pushing direction of the power supply battery 33. After moving to the lowered position, the electromagnet of the holding member 61 is turned on. At this time, as shown in FIG. 10, the battery lid 34 is pushed outward by the lower portion 61 b of the holding member 61.

  Next, as shown in FIG. 11, the control unit 64 controls the pushing member moving mechanism 62 to move the pushing member 60 to the lowered position. At this time, as shown in FIG. 12, the push-out claw 60a enters the notch 37c and pushes out the power supply battery 33 earlier than the pair of claws 60b and 60c. The pair of claws 60b and 60c are inserted into the gap between the strobe board 30 and the power battery 33 with a delay, and pushes the position near the negative side contact piece 35 in the body portion of the power battery 33. As a result, the stubborn plus side engagement is released first, and the minus side engagement is released later, so that the power supply battery 33 is pushed out substantially in parallel. As shown in FIG. 13, the extruded power battery 33 is magnetically attached in a posture in which the body portion enters the receiving portion 61 a of the holding member 61 and lies down on the side.

  As shown in FIG. 14, the holding member 61 holding the power battery 33 moves again to the standby position (discharge position) through the same movement locus. After moving to the standby position, the electromagnetic force of the holding member 61 is turned off to release the holding of the battery 33. Further, after the holding member 61 is moved to the standby position, the pushing member 60 is moved to the raised position. Thereby, the operation of one cycle of the battery removing device 65 is completed. Since the battery 33 is pushed straight out, the battery 33 is accumulated in the accumulation box 66 in a posture in which the polar directions are aligned. The integrated power supply battery 33 is inspected for battery capacity, and a battery whose inspected value is greater than a predetermined reference value is reused.

  In the MC short-circuit process ST10, the charge of the main capacitor of the strobe substrate 30 is discharged as described above.

  In the strobe discharging step ST <b> 11, the claw coupling between the main body base 16 and the strobe substrate 30 is released and the strobe substrate 30 is removed from the main body base 16. The removed strobe board 30 is sent to the inspection line, and the board that passed the inspection line is reused.

  In the lens holder discharging step ST12, a P & P device for removing the lens holder 21 from the exposure unit 18 is arranged. The P & P device includes a pair of chucks and a moving mechanism for moving these chucks at the tip of the robot hand, holds the lens holder 21 with the pair of chucks at the removal position, moves to the accumulation position, and moves to the accumulation position. The lens holder 21 is discharged and collected in the arranged collection box.

  In the photographic lens static elimination air blow step ST13, after removing the lens holder 21, air is blown toward the photographic lens 5 with an air nozzle to neutralize the surface of the photographic lens 5.

  In the photographing lens discharging step ST14, the photographing lens 5 is held at the removal position by the suction mechanism, moved to the transfer position, and aligned and stacked on the tray prepared at the transfer position. Unlike the lens holder 21, the photographic lens 5 has a disk shape with no opening for exposure, and is reused as it is. Therefore, in this step, the photographing lens 5 is held using a suction chuck so as not to be damaged. The suction chuck has a hollow cylindrical shape inside, and presses the periphery of the lower surface of the cylindrical shape against the flange of the photographing lens 5 to suck the photographing lens 5 with the hollow portion being a negative pressure. Then, the photographic lens 5 is separated from the suction chuck by releasing the negative pressure at the transfer position.

  In the objective lens discharging step ST16, the objective lens attached to the exposure unit 18 is removed. The removed objective lens is reused.

  In the NG discharging step ST18, the presence or absence of the lens holder 21, the taking lens 5, and the objective lens is checked by using a non-contact photoelectric sensor or the like to confirm whether or not the part removal operation has failed. A thing is taken out from the index table 43 as NG.

  In the exposure unit discharging step ST22, the claw coupling with the main body base 16 is released and the exposure unit 18 is removed from the main body base 16. The removed exposure unit 18 is sent to the exposure unit reuse line, and is reused by replacing parts as necessary.

  In the rear cover discharging step ST23, the winding knob 9 and the rear cover 15 are removed from the main body base 16. The rear cover 15 is removed while releasing the claw coupling. The removed take-up knob 9 and the rear cover 15 are returned to the raw materials and reused.

  In this way, the film unit 2 collects used ones, disassembles them into parts, and sends the reused parts to the assembly line for recycling production.

  In the above embodiment, the power supply battery 33 built in the lens-fitted photo film unit 2 is arranged on the bottom surface side. However, in the present invention, the power supply battery 33 is not limited to this and is arranged on the upper surface or on the left and right side surfaces. May be.

The push-out member 60 integrally having a pair of claws 60b and 60c that push the part is used. However, the present invention is not limited to this, and the pair of claws 60b and 60c is omitted, and the body part near the plus electrode is pushed. You may make it the structure which provided only the nail | claw 60a.

  In the above embodiment, the outer cover is constituted by the two covers of the front cover 14 and the rear cover 15. However, the outer cover is not limited to these and may be constituted by three or more covers. In this case, any one or a plurality of covers are removed and the power supply battery 33 is taken out. In the above embodiment, the front cover 14 is removed, and then the battery cover (part) 34 of the rear cover 15 is bent outward to expose one surface and the other surface of the power battery 33. The battery cover 34 of the rear cover 15 may be omitted, and the front cover 14 may be opened so that one surface and the other surface of the body portion of the power battery 33 are exposed by removing only the front cover 14.

  The holding member 61 that holds the power supply battery 33 is not limited to being held by magnetic force, and may be configured to be held by a pair of holding claws. Further, the take-out operation confirmation means 48 described in FIG. 5 may be provided in the battery discharge step ST9. In this case, after the removal work of the battery 33 is completed, the presence or absence of the battery 33 may be confirmed using a reflective photoelectric sensor or a magnetic sensor. In addition, the removal operation of the battery 33 is confirmed by detecting whether or not the holding member 61 holds the battery 33 on the movement locus on which the holding member 61 moves from the holding position to the standby position (discharge position).
