置的照相機，其中已就該發明提出第PCT/JP98/03 701號 的PCT應用以及1 999年3月4日發行的第W099/ 10772號 國際刊物。充電完成指示裝置會在主要電容器充電完全時 產生光信號。於這類應用中，會在遠離照相機的位置上知 會已充電完成。照相機在其前面含有閃光作業構件。當該 閃光作業構件滑到開啓位置時，閃光開關會被打開且充電 狀態指示器會期指示位置平移。使用一種柱狀光導當作充 電狀態指示器。該光導係可在用來使該光導的端點從相機 主體突出的突起位置與用來使該端點縮回相機主體內的縮 回位置之間垂直運動。紅色發光二極體（LED)會在閃光裝 置主要電容器充滿某一預定電壓時於相機主體內發生閃爍 。來自紅色LED的紅光會通過該光導內部而受到其端點的 投影。 對上述具有充電完成指示裝置之照相機的改良係說明於 第PCT/JP98/0442 5號PCT應用中，並於1 999年3月4日 發行的國際刊物中列入序號爲第W099 / 1 0772號的文件。 這類應用中的照相機係含有鏡頭蓋。在將鏡頭蓋設定在關 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） -----------•裝--------訂--------- (請先閱讀背面之注咅心事項再填寫本頁) 494268 五、發明説明（2 ) 閉位置上的同時，閃光作業構件係固定於關閉位置內且禁 止其於開啓位置內的運動。在將鏡頭蓋設定在開啓位置上 的同時，閃光作業構件係在開啓位置與關閉位置之間可移 動的。在將閃光作業構件設定在開啓位置上的同時，閃光 開關會被打開且光導會向外突出。在將閃光作業構件設定 在關閉位置上的同時，光導會移向縮回位置並關閉該閃光 開關。在將閃光作業構件設定在開啓位置上時且在將鏡頭 蓋移到關閉位置上的同時，會使閃光作業構件移到關閉位 置上並將光導移到縮回位置上。 閃光裝置通常係用來當作夜間攝影的照明光源。當閃光 裝置被用在日間攝影時，閃光燈是前光景色下使人類面部 之類過度曝光的因素。不過，當閃光燈的量額比太陽光小 很多時，這種很小的過度曝光係落在感光底片範圍的適當 區域內。因此，過度曝光的影響並未出現在相片上。若於 背光下使用該閃光裝置，則能夠防止人類面部在由曝光不 足的畫面所產生的相片上變黑。據此，較佳的是總在閃光 燈下攝影以防止錯過任何拍攝機會。 如上所述的照相機含有一種優點是在將鏡頭蓋設定於關 閉位置內的同時禁制了該閃光裝置的作業。不過，它同時 含有一種缺點是不僅必需將鏡頭蓋移動到開啓位置上，而 同時也必需操作閃光作業構件以便打開閃光開關並移動該 光導。這麼做會使照相機的作業整個變複雜。 爲了防止錯過任何拍攝機會，較佳的是提供某些作業用 構件以禁制該閃光裝置的充電作用，或是即使當該閃光裝 -4· 494268 A7 ___ B7_ 五、發明說明（3 ) 置是一種總會投影該閃光燈的型式時也能夠根據使用者的 意願從該閃光裝置發射閃光燈。這麼做能夠在前光景色下 有效地防止乾電池內能量的浪費並防止閃光燈受到反射性 物體的反射。 發明之扼要說明 依前述觀點，本發明的某一目的是提供一種易於操作的 照相機。 本發明的另一目的是提供一種具有充電狀態指示器之照 相機，其中當鏡頭蓋在關閉位置與開啓位置之間移動時， 該指示器會在用來使該充電狀態指示器從相機主體突出的 突出位置與用來使該充電狀態指示器縮回相機主體內的縮 回位置之間滑動。 本發明的又一目的是提供一種照相機，其中係藉由移動 該鏡頭蓋使閃光開關與該充電狀態指示器聯鎖。 本發明的再一目的是提供一種照相機，其中能夠在光投 影模式與充電禁制模式之間任意地選擇；且其中係在鏡頭 蓋係設定於開啓位置內的同時，藉由在突出位置與座落於 緊靠縮回位置之前的預縮位置之間改變該充電狀態指示器 的位置而作出選擇。 爲了達成上述及其他目的，根據本發明的照相機係含有 :鏡頭蓋；閃光開關；發光元件；充電狀態指示器；以及 聯鎖機構。在使鏡頭蓋滑入開啓位置而準備進行拍攝時， 聯鎖機構會將鏡頭蓋的運動傳送到充電狀態指示器上以致 該充電狀態指示器能夠在縮回位置與突出位置之間滑動。 - 5- 本紙張尺度適用中國國家標準（CNS)A4規格（210

Description of the Invention (1) Field of the Invention The present invention relates to a camera with a charging completion indicating device, and more particularly to the opening and closing of a lens cover. Interlocked charge completion indicator. Description of Related Art Japanese Patent Application Nos. JPA10-1 5381 4 and JPA1 1-6495 1 disclose a camera having a charge completion indicating device for a flash device, in which PCT / JP98 has been proposed for the invention / 03 PCT application No. 701 and International Publication No. W099 / 10772 issued March 4, 999. The charge completion indicator will generate a light signal when the main capacitor is fully charged. In this type of application, you will be notified that charging is complete at a distance from the camera. The camera includes a flash working member on its front. When the flash operation member slides to the on position, the flash switch will be turned on and the charging status indicator will shift the position. Use a cylindrical light guide as the charge status indicator. The light guide is vertically movable between a protruding position used to make the end point of the light guide protrude from the camera body and a retracted position used to retract the end point into the camera body. The red light-emitting diode (LED) flickers in the camera body when the main capacitor of the flash device is charged with a predetermined voltage. The red light from the red LED is projected through its ends by being projected through its interior. The improvement of the above-mentioned camera with a charging completion indication device is described in PCT application No. PCT / JP98 / 0442 No. 5 and is listed in the international journal issued on March 4, 1999, with serial number W099 / 1 0772. document. Cameras in this application include a lens cap. When setting the lens cap to this paper size, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applicable ----------- • Installation -------- Order-- ------- (Please read the note on the back before filling out this page) 494268 V. Description of the invention (2) At the same time as the closed position, the flash operation member is fixed in the closed position and it is prohibited to open it In-position motion. While the lens cover is set to the open position, the flash operation member is movable between the open position and the closed position. While setting the flash work member to the on position, the flash switch is turned on and the light guide protrudes outward. While setting the flash working member in the off position, the light guide moves to the retracted position and turns off the flash switch. When the flash work member is set to the open position and the lens cover is moved to the closed position, the flash work member is moved to the closed position and the light guide is moved to the retracted position. The flash device is usually used as a light source for night photography. When the flash device is used for daytime photography, the flash is a factor that overexposes human faces and the like in front light scenery. However, when the amount of flash light is much smaller than that of sunlight, this small overexposure falls in the appropriate area of the photosensitive film range. Therefore, the effect of overexposure does not appear on the photo. If the flash device is used in a backlight, it is possible to prevent a human face from becoming black on a photo produced by an underexposed picture. According to this, it is better to always shoot under the flash to prevent missing any shooting opportunities. The camera described above has an advantage in that the operation of the flash device is prohibited while the lens cover is set in the closed position. However, it also has a disadvantage that it is necessary not only to move the lens cover to the open position, but also to operate the flash operation member in order to turn on the flash switch and move the light guide. Doing so complicates the operation of the camera as a whole. In order to prevent missing any shooting opportunities, it is better to provide some work components to inhibit the charging function of the flash device, or even when the flash device-4.494268 A7 ___ B7_ V. Description of the invention (3) When the type of the flash is always projected, the flash can be emitted from the flash device according to the user's wishes. This can effectively prevent the waste of energy in the dry cell and prevent the flash from being reflected by reflective objects in the front light scenery. SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a camera which is easy to operate. Another object of the present invention is to provide a camera having a charge status indicator, wherein when the lens cover is moved between a closed position and an open position, the indicator is used to make the charge status indicator protrude from the camera body. Slide between the protruding position and a retracted position for retracting the charging status indicator into the camera body. Still another object of the present invention is to provide a camera in which a flash switch is interlocked with the charging state indicator by moving the lens cap. Still another object of the present invention is to provide a camera in which the light projection mode and the charging prohibition mode can be arbitrarily selected; and wherein the lens cover is set in the open position, and the projection position and the seat position A selection is made by changing the position of the charge status indicator between a pre-retracted position immediately before the retracted position. To achieve the above and other objects, a camera according to the present invention includes: a lens cap; a flash switch; a light emitting element; a charge status indicator; and an interlocking mechanism. When the lens cover is slid into the open position for shooting, the interlocking mechanism transmits the movement of the lens cover to the charging status indicator so that the charging status indicator can slide between the retracted position and the protruding position. -5- This paper size applies to China National Standard (CNS) A4 specification (210 χ ^ ^) ~ II ----- !! 4 (Please read the precautions on the back before filling this page) Order ------ !

Description of the invention It is turned on and the charging operation of the main capacitor of the flash device is started. When the main capacitor is fully charged with a predetermined voltage, preparations for flash photography are completed, and the light emitting element emits light. Light from the light emitting element will pass from one of the end points to the inside of the charge status indicator which will receive projection. When the lens cap is slid into the closed position, the charging status indicator is slid into the retracted position by the interlock mechanism and the flash switch is turned off. Use a light guide made of transparent plastic or glass as the charge status indicator. LED (light-emitting diode) is used as the light-emitting element. The light guide performs light emission from the light-emitting element to an end point protruding from the camera body. At one end of the light guide, a triangular groove is formed. In a preferred embodiment of the present invention, a light guide locking mechanism is provided in the camera. The light guide locking mechanism locks the light guide in the pre-retracted position σ immediately before the retracted position, and sets the flash device in the light projection mode while setting the lens cover in the open position. In the light projection mode, if the charging status indicator is pushed down from the protruding position to the retracted position, the light guide locking mechanism locks the charging status indicator in the pre-retracted position.

Description of the invention () 45a Even if it does not intersect the perpendicular line in the light incident surface 20d, the incident light can be diffused on the light incident surface 20d. The light emitted from the light emitting element 45 passes through the light guide body 20a and is projected by the first and second projection surfaces 20b and 20c which are flat. When viewed from the front of the camera 10, the first projection surface 20b projects the incident light forward when the main capacitor 40 is full and ready for flash photography. The second projection surface 20c projects the incident light backwards to indicate that the photographer is ready for flash photography. The pin 20e is composed of a driving portion 20g and a connecting portion 20h. The driving portion 20g operates the flash switch 52, and the connecting portion 20h is connected to the interlock mechanism 27. The bearing 20f is rotatably fitted into a pair of holes on a thin plate (not shown) for supporting the light guide 20 from the opposite side. The light guide 20 can rotate around the bearing 20f. The light guide 20 may also be translucent or have colors such as red, blue, and green. In addition, the light guide 20 has a columnar form and is slidable up and down, but it may also project vertically from the camera body 11 by sliding the lens cover 16.

Description of the invention (12). On the first arm 46a of the interlock lever 46, a cam slit 46d is formed so as to insert the connection pin 16b therein. At the end of the second arm 46b, a driving pin 46e is formed and positioned between the linear portions 47a and 47b on the connecting spring 47. The connection portion 20h of the light guide 20 is also positioned between the linear portions 47a and 47b on the connection spring 47 so as not to collide with the driving pin 46e. On the inner surface of the front cover 28, light stoppers 48 and 49 are formed. As shown in Figure 5, when the lens cap 16 is slid into the closed position, the connecting pin 16b will push the cam slot 46d of the interlock lever 46 so that the interlock lever 46 will loop around the hole in the counterclockwise direction. 46c rotation. The rotation of the interlocking lever 46 causes the connection spring 47 to swing in the clockwise direction when the driving pin 46e contacts the linear portion 47a of the connection spring 47, and the linear portion 47b moves the connection portion 20h to the left. According to the movement of the connection portion 201m, the light guide 20 rotates around the bearing 20f in the clockwise direction and is retracted into the camera body Π. As shown in FIG. 6, when the lens cover 16 is slid into the open position, the interlock lever 46 is rotated in the counterclockwise direction by moving the connecting pin 16b. When the interlock lever 46 is rotated, the driving pin 46e pushes the linear portion 47b of the connecting spring 47. Accordingly, the connection spring 47 swings in the counterclockwise direction, and the linear portion 47a moves the connection portion 20h to the right. The light guide 20 is rotated around the bearing 20 f in the counterclockwise direction by moving the connection portion 20 h and protrudes outward from the camera body 11.

Description of the invention (13) Printed on the rotation stroke of the lock lever 46 by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. The light guide 20 contacts the light stopper to make the distance between the linear portions 47a and 47b of the connecting spring 47 wider, so that the movement of the interlock lever 46 is not transmitted to the light guide 20. The connection spring 47 elastically converts the light guide 20 according to the sliding distance of the lens cover 16 after retracting the light guide 20 into the camera body 11 or protruding from the inside thereof. Accordingly, the connection spring 47 has a function of adjusting the lens cover 16. For example, in Figure 5, the lens cap 16 is slid over the position shown in the figure until the lens cap 16 hits the light stop 48. The rotation of the light guide 20 is stopped before the lens cover 16 hits the light stop 48. The distance between the linear portions 47a and 47b on the connecting spring 47 becomes wider to absorb the excessive rotation stroke of the interlocking lever 46 without loading the light guide 20 significantly. In addition, in FIG. 6, the rotation of the light guide 20 is prohibited until the lens cover 16 is slid into the open position, that is, the lens cover 16 hits the light stopper 49. Increasing the distance between the linear portions 47a and 47b on the connection spring 47 will absorb the excessive rotation stroke of the interlock lever 46 without loading the light guide 20 significantly. In addition, as shown in FIG. 7, while pushing the lens cover 16 to the closed position, push the light guide 20 upward strongly, and as shown in FIG. 8, while setting the lens cover 16 to the open position, firmly push The light guide 20 is pushed into the camera body 11. Also in this type of example, increasing the distance between the linear portions 47a and 47b of the connecting spring 47 will absorb the excessive rotation stroke of the interlock lever 46. As shown in Fig. 9A, the flash switch 52 is composed of a movable segment 50 and a fixed contact 39b. The movable section 50 is moved by the driving portion 20g, and the fixed contact 39b is formed on the second circuit board 39a.

Description of the invention (14) Segment 50 has a terminal portion 50a, a first arm portion 50b, a second arm portion 50c, and a contact portion 50d. The terminal portion 50a is firmly fixed to the first circuit board 39a with a solder 51. The first arm portion 50b is appropriately inclined with respect to the second arm portion 50c. As shown in FIG. 9A, when the light guide 20 is retracted into the camera body 11, the contact portion 50d is far away from the fixed contact 39b, and the flash switch 5 2 is held in the closed position. As shown in FIG. 9B, the driving portion 20g pushes the second arm portion 50c toward the second circuit board 39a while rotating the light guide 20 in the counterclockwise direction by sliding the lens cover 16. When the first arm portion 50b is bent under pressure, the contact portion 50d contacts the fixed contact 39b, and the flash switch 52 is turned on. When the flash switch 52 is turned on, the flash device starts to charge. In addition, as shown in FIG. 9C, when the light guide 20 is rotated to change the protruding position by rotation, the movable section 50 is more compressed by the driving portion 20g. The pressure will bend the second arm portion 50c to absorb the overstroke of the driving portion 20g. The contact portion 50d is pressed against the fixed contact 39b by bending the second arm portion 50c. Therefore, the contact between the contact portion 50d and the fixed contact 39b is stabilized. Then, the operation of the above embodiment will be explained. When the camera 10 is not used, the lens cover 16 is supported in the closed position by the lens cover locking mechanism. As shown in Fig. 5, the light guide 20 retracts the camera body 11 to stop the flash device. When shooting, press the lock release button 15 down to unlock the lens cover 16. Therefore, as shown in FIG. 6, the lens cover 16 is slid into the open position by the spring 17. -16- The scale applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) * I ----------- installation -------- order ------- -(Please read the note on the back before filling out this page) B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs V. Invention Description (15) (Please read the notes on the back before filling out this page) When the lens The cover 16 slides to the open position, and the interlocking lever 46 rotates clockwise as the connecting pin 16b slides to the cam slot 46d. When the connection spring 47 is connected to the interlocking lever 46 and the light guide 20, the rotation of the interlocking lever 46 causes the light guide 20 to swing in the clock direction and the upper end thereof protrudes from the camera body 11. At the same time, the driving portion 20g of the pin 20e may squeeze the movable section 50 so that the flash switch 52 may be turned on. Accordingly, the main capacitor 40 starts to be charged. When the main capacitor 40 is filled with a predetermined voltage, the light-emitting element 45 starts emitting instruction light at regular intervals. The flickering light emitted from the light emitting element 45 passes through the light guide body 20a and is projected by the first and second projection surfaces 20b and 20c. Both the photographer and the subject's eyes can recognize the indicator light projected from the first and second projection surfaces 20b and 20c when they are ready for flash photography. In addition, if the photographer is looking at the scene to be captured through the eyepiece window 30, the photographer can also see the blinking indicator light through the light-emitting hole 29a in the rear cover 29. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. When the shutter button 18 is pressed after the screen is fixed, the shutter will be activated for framing. The synchronous opening relationship is opened as the shutter blade is opened. When the sync switch is turned on, the flash discharge tube emits a flash due to the power supply from the main capacitor 40. The flash projector 14 containing the flash discharge tube projects the flash onto an object. During daytime shooting, the photosensitive film is exposed to a mixed light composed of reflected light from the subject flash and sunlight. During night shooting, the negatives are exposed only by reflections from the subject's flash. After filming, the motor in the film winding reel will be driven and the photosensitive bottom will be -17- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 494268 5. Description of the invention (16) The film has been exposed The portion is wound around the tension reel in the tension groove 32, and the unexposed portion on the photosensitive film for one frame is pulled out from the photosensitive film cassette 33. While winding the photosensitive film, set the shutter to the charging state. After the photosensitive film is wound, the main capacitor 40 automatically starts charging. As described above, while the main capacitor 40 is fully charged, the light guide 20 will project a flashing indicator light to inform that it is ready for flash photography. When the lens cover 16 is set to the open position, the flash device 25 is always set in the light projection mode with the flash projected on each shooting operation. Unless the photographer is to make flash photography, as shown in FIG. 8, the light guide 20 protruding from the camera body 11 is pushed down into the camera body 1 1 to turn off the flash switch. While the light guide 20 is held in the retracted position by hand, the main capacitor 40 is not charged. Actually, the flash device 25 is set in the charging prohibition mode to enable shooting without a flash. Even in the charging prohibition mode, if the main capacitor 40 is still charged, the flash device 25 projects a flash when shooting for the first time. However, since the second shot, each shot was taken without a flash. If a daylight-outdoor image is taken in the charging prohibition mode, the Bay II prevents the waste of power of the dry battery 36. When you remove your finger from the light guide 20, the light guide 20 moves from the retracted position to the protruding position. Therefore, the flash device 25 is set in the light projection mode. When the shooting should be finished, the lens cover 16 is slid into the closed position by operating the operation member 16a. When the lens cap 16 slides into the closed position, the lens cap 16 is locked by the lens cap locking mechanism. When the interlocking lever 46 is rotated in the counterclockwise direction by sliding the lens cover 16, the light guide -18- 494268 V. Invention Description (17) 20 is retracted into the camera body 11. At the same time, when the flash switch 52 is turned off, the main capacitor 40 stops charging. In the above embodiment, the light guide 20 must be continuously held down for non-flash shooting to complicate the operation of the camera 10. Therefore, it is preferable to provide a light guide locking mechanism for locking the light guide 20 in the retracted position. The figures 10 to 13 show that the first embodiment of the present invention 'includes a light guide locking mechanism. The lens cover 16, the light guide 20, and the interlock mechanism 27 all have the same structure as the first embodiment described above. Therefore, the same symbols are applied to the same components or parts and their explanations are omitted. In FIG. 10, the light guide locking mechanism 60 includes a sliding lever 61, a cam lever 62, and a spring 63. The coasting lever 61 can be attached to bearings 23a and 23b formed on the main unit 23 by fitting the openings 61a and 61b. The cam lever 62 is pushed in the clockwise sliding direction by a spring 63 connected to the light blocks 23c and 62a. The support pin 23d comes into contact with the cam lever 62 to adjust the rotation of the cam lever 62. The cam lever 62 includes a cam edge 62b, an opening 62c, a joint guide 62d, and a cam blade 62e which are inclined with respect to the front surface along the sliding direction of the sliding lever 61, so as to come into contact with the bonding ridge 61d. The bonding ridge 6 1 d slides on the cam edge 62 2b and enters the opening 62c in which the coupling guide 62d is formed. A pin 65 formed on one end of the light guide 20 is fitted into an opening 61c formed on one end of the sliding lever 61. Fig. 11 shows the light guide 20 and the light guide locking mechanism 60 when the lens cover 16 is set in the open position. The light guide 20 is completely retracted into the camera body 1 1 and the flash device 5 2 is turned off. The combination of the sliding lever 6 1 -19- 494268 A7 B7 V. Description of the invention (18) 61d is located behind the cam blade 62e. The cam lever 62 is pushed in the clockwise direction by the spring 63, but stops when the support pin 23d touches the support pin 23d. When the lens cover 16 is slid into the open position, the interlocking mechanism 27 causes the light guide 20 to protrude to the protruding position and sets the flash device 25 in the light projection mode. As shown in FIG. 12, while sliding the combination bump 6 1 d to the rear of the cam blade 62 e, the sliding lever 61 is slid to the right. When the joint bump 61 1 d is moved away from the cam lever 62, the cam lever 62 is seated on the sliding lever 61 so that the joint bump 61 d can be coupled to the cam edge 62b. For non-flash photography, the light guide 20 is pressed into the camera body 11 by hand. The light guide 20 rotates around the bearing 20f in a clockwise sliding direction (refer to FIG. 10) to oppose the force of the connecting spring 47. Thus, the sliding lever 61 will slide in the left direction and the combined bulge 6 1 d will slide on the cam edge 62b, so that the cam lever 62 may swing in the counterclockwise sliding direction. As shown in FIG. 13, when the light guide 20 reaches the near retracted position, the combined ridge 61d enters the opening 62c. The cam lever 62 is forced to swing in the clockwise sliding direction by the spring 63. Therefore, the coupling guide 62d contacts the coupling bulge 6 1 d, and the cam lever 62 stops the anti-clockwise swinging motion that once occurred. When the finger is removed from the light guide 20, the sliding lever 61 is slid to the right by the connection spring 47. At the same time, the cam lever 62 will start to swing in the clockwise sliding direction under the guidance of the joint guide 62d, and the joint ridge 61d will approach the cam blade 62e and come into contact with it. When the combined ridge 61d contacts the bottom surface of the cam blade 62e, the cam lever 62 will stop swinging. -20- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back first) (Fill in this page again.)

Description of the invention (19) In combination with the bump 6 1 d, you will be contacted The frame of the opening 62c is such that the sliding lever 61 may no longer slide in the right direction. (Please read the precautions on the back before filling this page.) Based on this, set the light guide 20 to the pre-retracted position near the retracted position. In the pre-retracted position, the light guide 20 protrudes slightly from the camera body 11 as shown in Fig. 13 and sets the flash switch to the off position. Even if the light guide 20 is not continuously held down by the hand, the flash device 25 can be set in the charging prohibition mode. When the light guide 20 in the pre-retracted position is pressed, the sliding lever 61 is caused to slide to the left, and the combined protrusion 61 d may slide from the upper end thereof to the rear of the cam blade 62 2e. The cam lever 62 is slightly swung in the clockwise sliding direction to contact the support pin 23d so that the bonding ridge 6 1 d is positioned behind the cam blade 62e (see FIG. 11). Therefore, when the finger is removed from the light guide 20, the sliding lever 61 is slid to the right by the connection spring 47 so that the light guide 20 may rotate toward the protruding position. When the flash switch 52 is turned on, the flash device 25 is set in the light projection mode. And the main capacitor 40 starts to be charged. The image is captured under the flash.

Description of the invention (20) The ridge 61d is used to slide from the upper end to the cam blade 62c. The cam lever 62 will swing in the clockwise sliding direction until it contacts the support pin 23d. Figures 14 to 16 show a third embodiment according to the present invention, in which the same symbols are applied to the same components or parts. In FIG. 14, the interlocking mechanism 70 is composed of a pin 7 1 b, an interlocking lever 72, and a spring 73. The pin 7 1 b is arranged on the back of the first arm 7 1 a on the lens cover 7 1. The lens cover 71 can be slid in a horizontal direction on a guide rail (not shown) disposed on the inner side of the front face. Such an appropriate static friction force between the lens cover 71 and the guide rail makes it possible for the lens cover 71 to stop at the selected position. The hole 74a and the pin 74b are formed on the light guide 74, and the hole 74a is sleeved with a bearing (not labeled) arranged on the main unit 23. The interlocking lever 72 has a nearly L-shaped form and includes a first arm 72a and a second arm 72b. The interlocking lever 72 is supported in a rotating manner by a combination of a hole 72c and a bearing 32a arranged outside the tightening groove 32. The hole 72d is attached to the pin 74b of the light guide 74. The spring 73 is supported by a bearing 32a (shown in Fig. 17) under the coil portion of the spring 73. One end of the spring 73 is connected to the second arm 72b, and the other end thereof is connected to the light stopper 32b formed on the surface of the tension groove 32 to push the interlock lever 72 in the clockwise sliding direction. The pins 7 1 b will contact the upper surface of the first arm 72 a to adjust the rotation of the interlock lever 72. On the lower end 74c of the light guide 74, switch contact sections 75a and 75b of the flash switch 75 are arranged. -22- This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) I -------------------- Order ------ --- Thread (please read the precautions on the back before filling this page) 494268 V. Description of the invention (21) When the lens cover 7 1 is slid to the closed position by operating the operating member 7 1 c, the pin 71b will press The upper surface of the first arm 72 a is turned to rotate the interlocking lever 72 in the counterclockwise sliding direction against the force of the spring 73. The light guide 74 is rotated around the hole 74a to the retracted position by rotating the interlock lever 72 in the clockwise sliding direction. Move the light guide 74 away from the switch contact blade 75a and set the flash switch 75 in the off position. As shown in FIG. 15, while the lens cover 71 is slid into the open position, the spring 73 will force the interlock lever 72 to swing in the clockwise sliding direction, so that the top of the first arm 7 2 a may be pressed and moved. In pin 7 1 b. By rotating the interlock lever 72, the light guide 74 is swung in a counterclockwise sliding direction to a predetermined protruding position near the hole 74a. When the light guide 74 is swung to the protruding position, the switch contact segment 75a is pressed down so that the lower end 74c of the light guide contacts the switch contact segment 75b, and the flash switch 75 is turned on. While the first arm 7 2 a presses the pin 7 1 b, the lens cover 7 1 is slid to the open position by the spring 7 3. The force of the spring 73 is smaller than the static friction force between the lens cover 71 and the guide slide rail, and is suitable for sliding the pin 7 1 b to contact with the first arm 7 2 a. Therefore, the lens cover 71 will not be subjected to the force of the spring 73 in an unexpected situation. In addition, if a chucking mechanism is provided, it is possible to prevent the lens cover 71 from slipping unexpectedly. As shown in Fig. 16, the charging state device 76 includes a light guide 74 and a light emitting element 77. The light guide 74 includes a light guide body 74d composed of a first projection surface 74e, a second projection surface 74f, and a light incident surface 74g. After the charging is completed, the light-emitting element 77 emits a flashing indication light, and makes the incident light incident on the light incident surface 7 4 g be projected from the first projection surface 7 4 e and the second projection -23- 494268 V. Description of the invention (22) Shadow 74 f goes out to inform the photographer that he is ready for flash shooting. The incident surface contains fine grooves. Figure 17 shows a fourth embodiment according to the present invention, which includes a light guide locking mechanism 60. The light guide 74 contains pins 7 4 b for inserting into the opening 6 1 c formed in the sliding lever 61 of the light guide locking mechanism 60. When the light guide 74 is pressed and locked in the pre-retracted position, as described above, the flash device 25 is set in the charging prohibition mode and can perform non-flashing shooting. When the light guide 74 is further pressed in the pre-retracted position, the light guide 74 is moved to the retracted position and the flash device 25 is set in the light projection mode. While the light guide 74 is set in the pre-retracted position, as described above, the lens cover 71 will not slide due to the static friction between the lens cover 71 and the guide rail. In the above embodiments, the first and second faces on the light guide are both flat. However, it is also possible to use light guides 80 and 81 as shown in Figures 18A and 18B. The light guide 80 shown in FIG. 18A includes a first projection surface 80a and a second projection surface (not labeled) formed with a triangular groove. The light guide 8 1 shown in FIG. 18B includes a first projection surface 8 1 a and a second projection surface (not labeled) in which a quadrangle is arranged on the first projection surface 8 1 a. In this structure, each light guide contains a surface having a size larger than that of each flat surface. In this embodiment, the illuminance of the flashing indicator light becomes stronger and easier to maintain. In the above embodiment, the lens cover is slid between the open position and the closed position along the horizontal direction. However, the lens cap may also slide or rotate vertically. In addition, although the photosensitive film is interchangeable in the cameras of the embodiments, the present invention can also be applied to a photosensitive film with a lens and a lens set in advance. -24- 494268 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Α7 Β7 9 ς 5.
