Abstract

PURPOSE:To reduce the generation probability of a water leakage accident, and to obtain a more accurate watertight structure, by forming an aperture for loading a film cartridge, on only the surface being roughly orthogonal to a cartridge shaft of a cartridge chamber. CONSTITUTION:An aperture 7 for loading a film cartridge P to a cartridge chamber 7 is formed on only the end face in the direction of a cartridge shaft Px of the cartridge chamber 6. Such a camera is constituted so that the film cartridge P which is loaded in the cartridge chamber 6 is driven to rotate. As it rotates, the tip of a film F protruded from the film cartridge P is guided to the inside wall of the cartridge chamber 6, and inserted automatically into a film feeding-out port. Accordingly, as for the aperture 7 for loading the film cartridge P to the cartridge chamber 6, if only the film cartridge P can pass through it in its longitudinal direction, it will surface. In such a way, the camera can be made small in size, and also, its peripheral length an be shortened, and an accurate waterproof structure is obtained.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides an annular structure which is held between the peripheral edge of an opening for loading a film cartridge into the cartridge chamber and a lid for this opening to keep the cartridge chamber in a watertight state. The present invention relates to a waterproof camera equipped with a sealing member.

C. Prior Art] Conventionally, in this type of waterproof camera, an opening for loading a film cartridge into the cartridge chamber is generally formed in the surface of the cartridge chamber along the cartridge axis direction. It is known that this opening is formed on the rear side of the body and the opening is closed with a back cover.

When loading the film cartridge into the cartridge chamber, this opening allows the film to be placed along the path from the cartridge chamber to the film exposure section.
It is constructed so that all of the film winding chamber etc. are open (for example, Japanese Patent Laid-Open No. 54-131926,
Or see Utility Model Application Publication No. 55-4463).

[Problem that the invention seeks to solve]

However, in the case of the above-mentioned conventional configuration, not only the cartridge chamber where the film cartridge is taken in and taken out, but also parts such as the film exposure section and the film winding chamber are opened at the same time. The portion sealed by the annular seal member is long in order to maintain the same temperature. Therefore, there is a problem in that there is a high probability of water leakage occurring due to deterioration of the sealing member or damage caused by contact with other objects.

In addition, the area of the opening for taking in and taking out the film cartridge is large, and the area of the lid that closes this opening must also be large, so the lid may warp and create a gap, which can lead to water leakage. There was also a risk that this would occur.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a waterproof camera having a more reliable watertight structure for a patrone chamber with a lower probability of water leakage.

[Means for solving problems]

A characteristic feature of the waterproof camera according to the present invention is that an opening for loading a film cartridge into the cartridge chamber is formed only on a surface that constitutes the camera body and is substantially perpendicular to the cartridge axis of the cartridge chamber. It is in.

[For production]

In other words, when loading a film cartridge into the cartridge chamber, the film cartridge is inserted into the cartridge chamber along the axial direction of the cartridge, and since the diameter of the film cartridge is small compared to its length, the opening The area and its circumference can be made smaller compared to conventional configurations.

In particular, when this opening is formed only on the end face of the cartridge chamber in the cartridge axis direction, it is possible to create an opening with the minimum area and circumference necessary to take the film cartridge in and out of the cartridge chamber. It becomes.

That is, as will be described later, the film cartridge (P) loaded in the cartridge chamber (6) is configured to be rotated, and along with this rotation, the film coming out of the film cartridge (P) is rotated. The tip of (F) is guided by the inner wall (68) of the cartridge chamber (6) and is configured to be automatically inserted into the film outlet (6c) from the cartridge chamber (6).

Therefore, the film cartridge (P) is transferred to the cartridge chamber (6
) The opening (7) for loading the film cartridge (P) may simply be one that allows the film cartridge (P) to pass through it in its longitudinal direction, and can be made small, have a short circumference, and be sure to be watertight. This gives us structure.

Furthermore, the 0 ring (
11) is formed so that the O-ring (11) is positioned on almost the same plane when the lid (8) is closed, thereby securing the watertight structure of the cartridge chamber (6). By making it dimensional, it is constructed to ensure reliable watertightness.

Further, a shaft (8a) is erected on the inner wall of the lid (8), and a conical guide member (12) is attached to the tip of the shaft (8a).

The film cartridge (P) is positioned in the radial direction by engaging with the film cartridge (P).

Furthermore, a rotation prevention plate (

On the other hand, a pair of leaf springs (15) are attached to the inner wall of M (8), and the free ends of the pair of temporary springs (15) are respectively attached to the projections (13a) of the rotation prevention plate (13). They are in elastic contact. The rotation prevention plate (13) is urged upward by the elasticity of the temporary spring (15), and the tip of the leaf spring (15) comes into contact with the upright surface of the protrusion (13a). Rotation in the counterclockwise direction in FIG. 3 is prevented.

In other words, the film cartridge (P) is located in the cartridge chamber (
6), unless a force exceeding the frictional force between the elastic friction member (14) and the lower end surface (Pb) of the film cartridge (1') is applied, the film will not move in the unwinding direction. is designed not to rotate.

The cartridge chamber (6) is formed into a substantially cylindrical shape as shown in FIGS. Px) has an inner diameter that can be rotated around. That is, the inner diameter of the cartridge chamber (6) is [DI], and the distance from the center of the film cartridge (P) to the film drawer part (Pa

In addition, as shown in FIG. 4, the top of the cartridge chamber (6) includes three guide levers (16), a cartridge detection hinge (17), and a cylindrical shape on the protruding side of the film cartridge (P). A drive shaft (18) is provided that fits into the cartridge shaft (hereinafter referred to as the upper cartridge shaft) (Pxt) and transmits rotational drive to the cartridge shaft (Px).

The three guide levers (16) are arranged in a circumferential direction of the patrone chamber (6) so as to be out of phase with each other by 120 degrees. Each guide lever (16) is formed on the ceiling surface (6a) at an upright position shown by the two-dot chain line in FIG. ? 1
(6b) It is rotatably attached to the retracted position where it enters the inside. and a spring (not shown)
, they are each urged toward the upright position.

As the loaded film cartridge (P) is inserted deep into the cartridge chamber (6), the three-wooden guide lever (16) moves the upper end surface (
Pt) is pushed to the retracted position against the biasing force of the spring, and its tip pushes the upper cartridge shaft (Pxt) toward the center of the cartridge chamber (6), causing the upper cartridge to Guide the drive shaft (18) so that it is engaged with the shaft (Pxt). Note that the number of guide levers (16) is not limited to three, and may be any number that does not interfere with guiding the upper cartridge shaft (Pxt) of the film cartridge (P) toward the center of the cartridge chamber (6). Any number is fine.

The cartridge detection pin (17) can freely move in and out between a protruding position where it protrudes from the ceiling surface (6a) of the cartridge chamber (6) into the cartridge chamber (6) and a retreat position where it retreats from the cartridge chamber (6). It is attached to the spring (
19) toward the protruding position. This cartridge detection pin (17) is pushed by the upper end surface (1't) of the film cartridge (P) inserted into the cartridge chamber (6) and moves to the retracted position, and the normally open loading switch (S2
).

The drive shaft (18) includes a protrusion (18a), a plate portion (18b) with a width that can be inserted into the upper cartridge shaft (Pxt), and a transmission shaft (20) connected to the gear (G26). It consists of a cylindrical part (18c) to fit into. A pin (20a) provided on the circumferential surface of the transmission shaft (20) is fitted into a longitudinally elongated hole (18d) formed in the cylindrical portion (18c), and the drive shaft (18) is configured as a whole to be able to slide in the axial direction with respect to the transmission shaft (20) and to rotate integrally with the transmission shaft (20).

Further, this drive shaft (18) is urged toward the film cartridge (P) side (lower side in the figure) by a spring (21). Then, the plate portion (18b) engages with a groove (not shown) in the upper cartridge shaft (Pxt).

Further, the pressure roller (23) is rotatably supported and pressed against the film conveyance roller (22). As the film transport roller (22) rotates, the film (F) sandwiched between the rollers (22) and (23) is transported in the left-right direction in the figure according to the rotation direction. There is.

(33) is provided. This pair of light shielding members (32
) and (33) are each made of an elastic member such as rubber, which has a light-shielding property, and are attached with their tip portions elastically abutting each other. This pair of light shielding members (32
), (33) means that when the lid (8) is open, light leaking from the film outlet (6C) of the cartridge chamber (6) is transmitted to the film exposure section (25) and the spool chamber (2).

In addition, light shielding may be further ensured by attaching a light shielding cloth such as a telescope to the surfaces of the light shielding members (32) and (33) that contact each other.

Next, the drive shaft (18
), film transport roller (22), and spool (
In 29), the drive transmission mechanism that transmits the driving force from the motor (M) will be explained.

As shown in Fig. 6, the gear (G1) fixed to the rotating shaft (Ma) of the motor (M) constitutes the reduction gear train (G2), (G3), (G4), (G5).
, (G6), and (G7) are interlocked and connected to the gear (G8). The gear (G8) has a pair of upper and lower gears (G9) and (GIO) in the figure.
It is fixed so that it rotates together with the

The lower gear (GIO) in the figure is coupled to a gear (Gll) that rotates integrally with the spool (29).

In other words, the rotation of the gear (G1) accompanying the rotation of the motor (M) rotates the spool (29) in a direction opposite to the rotational direction of the motor (M).

On the other hand, the gear (G8) in the upper part of the figure rotates together with the gear (G8).

4) It is connected to the sun gear (G17) via , (G15) and (Gi6). The planetary gear (GlB) that meshes with the sun gear (G17) is a lever (35) rotatably supported on the rotation shaft (34) of the sun gear (G17).
is rotatably attached to.

When the sun gear (G17) rotates in the direction A in the figure, this planetary gear (GlB) moves to a position where it meshes with the gear (G19), and when the sun gear (G17) rotates in the direction B in the figure. , and move to a position where it meshes with the gear (G20).

The gear (G19) is fixed to the drive shaft (22a) of the film transport roller (22), and the gear (G21)
) and (G22) to the gear (G23). This gear (G23) is connected to a drive shaft (18) for the film cartridge (P) via a one-way clutch (36). One-way clutch (36
) is configured to transmit its rotational force to the drive shaft (18) only when the gear (G23) rotates in the direction A in the figure. On the other hand, gear (G20) is gear (G24), (
A gear (G25) fixed to the drive shaft (20)
26).

The operation of the drive transmission mechanism configured as above will be explained.

When the rotating shaft (Ma) of the motor (M) rotates in the direction B in the figure, the spool (29) rotates in the direction A in the figure, that is, in the direction in which the film (F) is wound up. In addition, the sun gear (G
17) rotates in the direction A in the figure, and the planetary gear (G18) meshes with the gear (G19), so that the film transport roller (
22) rotates in the direction A in the figure, that is, in the direction of conveying the film to the spool chamber (28) in cooperation with the pressure roller (23). Furthermore, the drive shaft (18) for the film cartridge (P) rotates in the direction A in the figure, driving the cartridge shaft (Px) in the direction in which the film (F) is unwound.

As a result, the film in the film cartridge (P) (
F) is transported to the left in the figure by the film transport mechanism (FT), passes through the film exposure section (25), reaches the spool chamber (28), and is wound around the outer periphery of the spool (29). Also, at this time, the film transport mechanism (FT)
The transport speed of the film (F) according to the spool (29)
The winding speed of the film (F) is faster than the unwinding speed of the cartridge shaft (Px).

Therefore, even if the winding speed of the film (F) on the spool (29) increases gradually due to the thickening of the film (F), the film (F) will not be wound up faster than the transport speed of the film transport mechanism (FT). is prevented from protruding.

In addition, the winding speed of the film (F) by the spool (29) is set to be the fastest, then the transport speed of the film (F) by the film transport mechanism (FT) is set to be the fastest, and the cartridge shaft (P
The drive transmission mechanism may be configured so that the unwinding speed of x) is the slowest. In this case, the spool (29) will rotate faster than the film transport speed, but a friction mechanism is inserted in the spool (29) or in the drive transmission mechanism to drive the spool (29) by friction. You can configure it like this. That is, the spool (
This is because the increase in the winding speed due to the thickening of the film in 29) is absorbed by the friction mechanism.

On the other hand, when the rotating shaft (Ma) of the motor (M) rotates in the direction shown in the figure, the spool (29) rotates in the direction B in the figure.

In addition, the sun gear (G17) rotates in the direction B in the figure, and the planetary gear (GlB) meshes with the gear (G20), so that the drive shaft (18) for the film cartridge (P) is rotated in the direction B in the figure.
direction, rotate the cartridge shaft (Px) to the film (F
) is driven in the direction in which it is caught. The rotation of the drive shaft (18) in the direction B in the figure is controlled by the one-way clutch (3).
6) to the gear (G23), further transmitted to the gear (G19) via the gears (G22) and (G21), and the drive shaft (2) of the film conveying roller (22).
2a) is driven and rotated in the direction B in the figure.

This causes the film (
F) is transported to the right in the figure by the film transport mechanism (FT) and rewound into the film cartridge (P).

On the other hand, there are stripes for film measurement. As already mentioned, the rocket (27) is configured to be driven by engaging with the perforations of the film (F) being conveyed. This film measuring sprocket (27) is connected to the - piece switch operating mechanism (
38) and a film counter (39).

The one-frame switch operating mechanism (38) is linked to the shutter (24), and closes the one-frame switch (S5) when the exposure of one frame of film (F) is completed, and closes the one-frame switch (S5) to open the film measurement sprocket. ) (27) is driven and the sprocket operating mechanism (37) detects the completion of winding one frame of film (F), the - frame switch (S5) is opened.

Further, the film counter (39) changes the display on the display device (40) according to the operation of the sprocket operation mechanism (37), and also changes the display on the display device (40) according to the operation of the sprocket operation mechanism (37).
) to open and close the initial hoisting switch (S4). This initial winding switch operating mechanism (41) closes the initial winding switch (S4) until the film counter (39) detects the -th frame of the film (F), and the film counter (39) The initial winding switch (S4) is configured to open when the -th frame (F) is detected.

Next, the motor drive circuit shown in FIG. 7, which drives the motor (M) involved in transporting the film (F), will be explained.

In this circuit, (Sl) is the main switch, (S2
) is the loading switch shown in Fig. 2 that is closed when the film cartridge (P) is stored in the cartridge chamber (6), and (S3) is the loading switch that is closed when the lock lever (9) is in the lock position. The lock switch shown in Figure 2 (S4)
6 is the initial winding switch shown in FIG. 6 which is closed until the film counter (39) counts the -th frame from the initial state, and (S5) is opened when winding of the film (F) for -th frame is completed. The one-frame switch shown in FIG. 6, which is closed when the exposure is completed, (S6) is a rewind lever (not shown).
A rewind switch (S7) is closed when the film (F) is at the rewind position, and a rewind completion switch (S7) is closed when the film (F) is completely rewinded.

The motor (M) is connected to a battery (E) as a power source via a main switch (Sl) and a pair of relay switches (RLI) and (RL2). Both relay switches (RLI) and (RL2) are activated by conduction of respective transistors (Tl) and (T2), respectively, and connect the motor (M) and the power source battery (E).

Furthermore, when both relay switches (RLI) and (RL2) are not in operation, both electrode terminals of the motor (M) are short-circuited and the motor (M) is stopped. And a pair of transistors (Tl), (T
2) At the base are transistors (T3) and (T4).
The collectors of the transistors (T3) and (T4) are connected to each other, and when the transistors (T3) and (T4) are turned on, the transistors (Tl) and (T2) are turned off, and the corresponding relay switch (RLI) is turned on. ), (R
L2) becomes inactive.

One input terminal of the AND circuit (ANI) is connected to the connection point between the loading switch (S2), the lock switch (S3), and the pull-down resistor (R1), and the other input terminal is connected to the initial winding switch (S4). It is connected to the connection point with the pull-down resistor (R2). That is, AND circuit (ANI)
There are three switches (S3) and (S4).

When both (S5) are closed, an "H" level signal is output.

One input terminal of the OR circuit (ORI) is connected to the AND circuit (A
The other input terminal is connected to the connection point between the one-piece switch (S5) and the pull-down resistor (R3). The output terminal of the OR circuit (ORI) is two transistors (Tl).

(T4) is connected to the base. That is, the OR circuit (
ORI) outputs an "H" level signal upon receiving a "H" level signal from the AND circuit (ANI) or when the - piece switch (S5) is closed. From this series, there are two transistors (TI).

(T4) becomes “ON” state, and the relay switch (RLI
) operates and the motor (M) rotates forward.

In addition, the output terminal of the OR circuit (ORI) is connected to the inverter (
It is connected to the base of the transistor (T5) via IN3). This transistor (T5) includes a constant current circuit (CC), a capacitor (C1), a constant voltage circuit (CE),
Together with the comparator (CPI), it constitutes a timer circuit. Comparator (CPI) is “ON”
The transistor (T
5) outputs a signal at the "I(" level) when the charging voltage of the capacitor (C1) becomes higher than the voltage of the constant voltage circuit (CE) by continuing the "OFF" state for a predetermined time. The output terminal of (CPI) is connected to one input terminal of an OR circuit (OR2).The other input terminal of this OR circuit (OR2) is connected to an inverter (I
N2) is connected to the connection point between the -piece switch (S5) and the pull-down resistor (113). That is, in the OR circuit (OR2), the comparator (CPI) is “I(”
When a level signal is output, or - piece switch (
When S5) is opened, it outputs an "H" level signal.

One input terminal of the AND circuit (AN2) is the OR circuit (O

The output terminal of is connected to the base of the transistor (T3). That is, the AND circuit (AN2) outputs an "L" level signal while the AND circuit (ANI) outputs a "L" level signal.
When the OR circuit (OR2) outputs a signal at "H" level, it outputs a signal at "H" level. As a result, the transistor (T3) becomes “ON” and the motor (M
) will stop.

On the other hand, the bases of the two transistors (T2) and (T3) are connected to the rewind switch (S6) and the pull-down resistor (R4).

S6) is closed, the two transistors (T2
) and (T3) are both in the "ON" state, the relay switch (1?L2) is activated, and the motor (M) is reversed. Further, the base of the transistor (T4) is connected to the connection point between the rewinding completion switch (S7) and the pull-down resistor (R5). That is, when the rewinding completion switch (S7) is closed, the transistor (T4) is turned on, and the morph (M) that is being reversed stops.

This rewinding completion switch (S7) is connected to the film conveyance roller (22) in the film (F) conveyance path and the pressure roller (
23). The film (F) is present at that position and is opened when it comes into contact with the film (F), and is configured to be closed when the film (P) is not present. Rewind completion switch (S
In 7), instead of this configuration, for example, both the film conveyance roller (22) and the pressure roller (23) are formed from conductive materials, and they contact each other when the film (F) is not present. It may be configured such that the film (F) is closed between the two and opened when the film (F) is present between them.

When inserting the film cartridge (P), the groove in the upper cartridge shaft (Px t) and the plate part (1) of the drive shaft (18)
8b) are provided so as to smoothly engage with each other.

If the plate portion (18b) of the drive shaft (18) does not fit into the upper cartridge shaft (Pxt) when inserting the film cartridge (P), the drive shaft (18)
), it is once pushed into the ceiling surface (6a) of the cartridge chamber (6), and then when the drive shaft (18) starts rotating, it is engaged in the upper cartridge shaft (Pxt). is configured to enter. In this state, the tip of the film (F) is held in the cartridge chamber (6) by its own elasticity.
) is in elastic sliding contact with the inner wall (6A).

Furthermore, in FIG. 2, when the film cartridge (P) is inserted, the cartridge detection pin (17) moves upward in the figure against the biasing force of the spring (19), and the loading switch (S2) closes. will be accomplished. Also, lock lever (9)
is rotated to the lock position, the lock switch (S
3) is closed. At this time, the main switch (Sl)
is assumed to be closed. Further, the initial winding switch (S4) is closed because the film counter (39) is in the initial state.

Therefore, in FIG. 7, the AND circuit (ANI) and the OR circuit (ORI) output an "H" level signal, and the transistor (T1) becomes "ON" and the motor (M)
starts rotating forward. This normal rotation is caused by the film counter (3
9) detects the -th frame of the film (F), the initial winding switch (S4) is opened, and the - frame switch (S5) is opened.
) will continue until it is released.

In Fig. 5 (a) to c) and Fig. 6, when the motor (M) rotates in the normal direction, that is, when the rotating shaft (Ma) rotates in the direction B in the figure, the spool (29) is rotated. Rotates in direction A in the figure. In addition, the planetary gear (G18) meshes with the gear (G19), and the film transport roller (22)
) and the drive shaft (18) rotate in the direction A in the figure.

By rotating the drive shaft (18) in the direction A in the figure, the cartridge shaft (Px) is rotated in the direction in which the film (F) is unwound. Film (F) is a film cartridge (P
) Since there is frictional resistance between the film drawer (Pa) and the telescope, the rotation of the cartridge shaft (Px) causes the film (F) to be pushed into the film cartridge (P).
It expands in the axial and radial direction inside and comes into pressure contact with the inner wall of the film cartridge (P). In this state, Patrone 1J
Ih (Px), film (F), film cartridge (P), and film cartridge (P) come to rotate integrally.

As shown in FIG. 2, an elastic friction member (14) biased by a leaf spring (15) is in contact with the lower end surface (Pb) of the film cartridge (P).
The rotation prevention plate (13) and the plate spring (15) are connected to the rotation prevention plate (14).
) is adapted to allow rotation of the film (F) in the feed direction, and the film cartridge (P) starts rotating in the input direction in FIG. 5(A) together with the film (F). Along with this rotation, the leading edge of the film (F) moves in the direction shown in the figure while slidingly contacting and being guided by the inner wall (6^) of the cartridge chamber (6).
) to the film delivery port (6c) formed at the top.

Then, as shown in FIG. 5 (II), the film (F)
The tip of the film passes through the film delivery port (6c) and is inserted between the film transport roller (22) and the pressure roller (23). The film conveyance roller (22) is driven and rotated in the direction A in the figure, and the film (F) is conveyed to the left in the figure.

Then, the film (F) reaches the spool chamber (28) after passing between the film exposure section (25) and the film pressure bonding plate (26), and as shown in FIG. ) along the spool (29) in the direction A in the figure.

As mentioned above, the motor (M) rotates forward and the film (F)
When the winding operation is performed, as mentioned above, the speed at which the film (F) is unwound from the cartridge shaft (Px) due to the rotation of the drive shaft (18) depends on the film transport rollers (22) and (23). The transport speed is set to be slower than the transport speed of the film (F). Therefore, as the winding operation of the film (F) progresses, the initial looseness of the winding of the film (F) gradually decreases and eventually disappears.

After that, the film wrapped around the cartridge shaft (Px) (
F) will be forcibly solved, so the drive shaft (18
) is rotated faster than the rotational speed of gear (G23).

However, as shown in FIG. 6, there is a gap between the drive shaft (18) and the gear (G23) due to the rotation of the gear (G23) in the direction A in the diagram. Since a one-way clutch (30) that only transmits rotation in the B direction is provided, no inconvenience occurs.

Then, the film measuring sprocket (27) starts rotating when it engages with the perforation at the leading end of the film (F) being conveyed, and as already mentioned, the film counter (39) and the frame are rotated. Mechanism (38
). A film counter (39) counts the number of film (F) based on the count of perforations.
When the leading edge of the frame is detected, the initial winding switch (S4) is opened, and when it is detected that the -th frame of the film (F) is located in the film exposure section (25), the - frame switch (S5) is opened. It will be released.

As a result, in FIG. 7, the AND circuit (ANI) and the OR circuit (ORI) both output "L" level signals, the transistor (T3) becomes "ON" and the motor (M) stops. do.

2> Imaging operation and winding operation The film (
After the initial hoisting of F) is completed, press the initial hoisting switch (S
4) remains open, and the output signal from the AND circuit (ANI) maintains the "L" level.

In this state, when a shirt release operation is performed using a release button (not shown), the film (F) is exposed by the shutter (24), and then the - frame switch (
S5) is closed.

Therefore, in FIG. 7, from the OR circuit (ORI)
``'''' level signal is output and transistor (TI) is O.
N” state and the motor (M) rotates forward.

As a result, in FIG. 6, the drive shaft (18), film conveyance roller (22), and spool (29) are
Both rotate in the direction A in the figure, and the film (F) is conveyed to the left in the figure. At this time, the released shutter (2
4) is designed to be charged again by a shutter charge mechanism (not shown).

On the other hand, the film measurement sprocket (27) is driven by the transported film (F) and rotates in the direction A in the figure.
The film counter (39) is actuated via the sprocket actuation mechanism (37).

When the transport of the film (F) to the -sternum is completed, the one-frame switch (S5) is opened via the -frame switch operating mechanism (38), and the motor (M ) stops.

<3> Film tension detection operation During the film winding operation described in 2> above, the OR circuit (O
Since the output signal from the inverter (IN3) is at the "L" level while the signal at the "I]" level is being output from RI), the transistor (T5) is in the "OFF" state. The capacitor (C1) is charged by the current from the current circuit (CC).

Even if the winding operation of the film (F) continues for a predetermined period of time (i.e., a period slightly longer than the time normally required to wind the film (F) up the sternum), the one-frame switch (S5) is activated.
If the capacitor (C1) is not opened, the charging voltage of the capacitor (C1) increases and becomes higher than the voltage of the constant voltage circuit (GE), and the output signal of the comparator (CPI) is inverted to the "°H" level. At this time, the output signal from the AND circuit (ANI) is at "L" level, so the AND circuit (AN2
) is open, and the "H" level signal from the comparator (CPI) passes through the OR circuit (OR2) and is output from the AND circuit (AN2). Therefore, the transistor (T3) becomes "ON" and the motor (M)
stops.

This state usually occurs when the film (F) stops being fed when all frames of the film (F) have been photographed or when some other trouble occurs. That is, the film measuring sprocket (27) is not driven and the - frame switch (S5) is not opened even after a predetermined period of time has elapsed.

On the other hand, when the film is being transported normally, the one-frame switch (S5) is opened within a predetermined period of time, so that the output signal from the OR circuit (ORI) becomes "L" level. Then, the transistor (T5) enters the “○N” state via the inverter (IN3), so the capacitor (C1
) is discharged, thereby returning the capacitor (C1) to its initial state.

4> Film rewinding operation The film rewinding operation is set by operating a rewinding lever (not shown). In FIG. 7, when the rewinding switch (S6) is closed, the transistor (T2) is turned on. ON” state, the relay switch (RL2) operates and the motor (M)
is reversed. As a result, in Fig. 6, the drive shaft (1
8), the film transport roller (22), and the spool (29) all rotate in the B direction in the figure, and the spool (2
The film (F) wound around 9) is conveyed to the right in the figure.

During the rewinding operation, as the drive shaft (I8) rotates,
A film (F) locked to the cartridge shaft (Px),
The film cartridge (P) itself receives rotational force due to friction between the film drawer part (Pa) and the television. However, an elastic friction member (14) is in contact with the lower end surface (Pb) of the film cartridge (P), and its frictional force is greater than the frictional force between the film CF) and the television. The rotation prevention plate (13) to which this elastic friction member (14) is attached prevents the rotation of the film (F) in the unwinding direction by the engagement of its protrusion (13a) with the temporary spring (15). Since it is blocked, the film cartridge (P) does not rotate.

In other words, the elastic friction member (14), the rotation prevention plate (work 3),
The leaf spring (15) constitutes a cartridge reversal prevention mechanism (RI) that prevents rotation of the film cartridge (P) during film rewinding.

Therefore, the film transported to the right in FIG. 6 is rotated by the drive shaft (18).
) is rewound. When the film (F) is completely rewound into the film cartridge (1'), the rewind completion switch (S7) is closed. As a result, in Fig. 7,
Transistor (T4) becomes "ON" state, transistor (T2) becomes "OFF" state and motor (M)
stops.

In the previous embodiment, the cartridge rotation drive mechanism (PM) is provided with a drive shaft (18) that engages with a groove in the upper cartridge shaft (1'xt). The specific configuration of the patrone rotation drive mechanism (PM) can be changed as appropriate, and one example will be described next.

As shown in FIGS. 9(a) to 9(c), a pair of support levers (51
), (52) are separate mounting shafts (51a), (5
2a) is rotatably supported. Both levers (51)
, (52), cartridge support rollers (53), (54) are rotatably supported, respectively.

These support levers (51) and (52) are linked to the operation of M (8) of the cartridge chamber (6) via an interlocking mechanism (not shown), and when the lid (8) is in the open position, The support levers (51) are in the retracted position shown in FIG. 9(a), and move to the operating position shown in FIG. (
52) is in the operating position, the pair of cartridge support rollers (53) and (54) are configured to support the upper cartridge shaft (Pxt) from the sides, respectively.

In the figure, (55) is a sun row arm, which is supported by a mounting shaft (55a) and is operatively connected to a drive mechanism (not shown) so that it can be rotated in both directions. This drive mechanism is almost the same as the drive mechanism in the previous embodiment shown in Fig. 6, and in this embodiment, a sun roller (55) is provided in place of the drive shaft (18) in Fig. 6. You can think that.

A lever (56) is rotatably supported on the mounting shaft (55a) of the sun roller (55). This lever (
A pair of planetary rollers (57),
(58) is rotatably supported. Both planetary rollers (57) and (58) are frictionally coupled to the sun roller.

When the sun roller (55) rotates in the direction A in the figure, the lever (56) rotates and the planetary roller (58) moves around the outer circumference of the upper cartridge shaft (Pxt), as shown in FIG. 9(b). The rotation of the sun roller (55) causes the planetary roller (58
) to rotate the cartridge shaft (Px) in the direction shown in the figure. On the other hand, when the sun roller (55) rotates in the direction B in the figure, the lever (
56) rotates, and the ix crawler 57) comes into contact with the outer periphery of the upper cartridge shaft (Pxt), and the rotation of the sun roller (55) is transmitted via the planetary roller (57), causing the cartridge shaft (Px) to rotate. Rotate in direction B.

In this configuration, for example, even if the upper cartridge shaft (Pxt) is inserted at a position slightly away from the center of the cartridge chamber (6), as shown by the broken line in FIG. 9(A), the M(8) A pair of support levers (51)
, (52) move from the retracted position to the active position, the pair of cartridge support rollers (53), (54)
The upper cartridge shaft (Pxt) is pushed toward the center position, and the posture of the film cartridge (P) is corrected.

The lever (56) is biased with a weak force so that the sun roller (55) stops at the position shown in FIG. 9(a) when it is not being driven to rotate. Therefore, even if the upper cartridge shaft (Pxt) of the film cartridge (P) inserted into the cartridge chamber (6) is biased toward the sun roller (55), when the sun roller (55) is driven and rotated, , by either planetary roller (57 or 58).

Next, yet another embodiment will be described. Figure 10 and 1
In the case shown in FIG. 1, the configuration of the cartridge chamber (6) is different, and the cartridge rotation drive mechanism (PM) is configured accordingly.

As shown in FIGS. 10(a) to 10(c), the inner diameter of the cartridge chamber (6) is measured from the outermost edge of the film drawer (Pa) of the film cartridge (P) to the cartridge shaft (P).
It is formed to be slightly larger than the distance from the center of x) to the peripheral wall of the opposing film cartridge (P). That is, the inner diameter of the cartridge chamber (6) is [D! ], the distance from the center of the film cartridge (P) to the outermost edge of the film drawer (Pa) is [dl], and the distance from the center of the film cartridge (P) to the outermost edge of the film cartridge (P) is
If the radius of the cylindrical part is [aZ, then 2·d, >D, >d, +d2. Therefore, the patrone room (6)
Inside, as the film cartridge (P) rotates, the cartridge shaft (Px) eccentrically rotates.

Therefore, as shown in FIG. 11, the protrusion (18a) and plate portion (18) of the drive shaft (18) in the embodiment shown in FIG.
b) and a protrusion (59a) and a plate (59b) corresponding to
) with a drive plate (59), a transmission spring (60)
Through the transmission shaft (20) in the embodiment shown in FIG.
are linked together. This transmission spring (60) is
In the free state, it stands upright and supports the drive plate (59). Meanwhile, the film cartridge (
P) is loaded, the drive plate (59) is elastically deformed as shown in FIG. 11 while being engaged with the groove in the upper cartridge shaft (Pxt). This allows the driving force to be transmitted to the cartridge shaft (Px) while the drive plate (59) is eccentric with respect to the center of the cartridge chamber (6).

As a result, the film cartridge (P) is driven and rotated with the cartridge shaft (Px) being eccentric with respect to the cartridge chamber (6).

In this configuration, the inner diameter of the cartridge chamber (6) can be reduced. In addition, by setting the inner diameter of this cartridge chamber (6) to an appropriate size, the cartridge axis (Px) of the inserted film cartridge (P) can be aligned with the center (C) of the cartridge chamber (6) in plan view. Can be made always inclusive.

That is, for example, by arranging the protrusion (59a) of the drive plate (59) approximately at the center of the cartridge chamber (6), the film drawer (Pa) can be moved to any position around the cartridge axis (Px). Even if the film cartridge (P) is inserted in the state of
The plate portion (59b) smoothly engages with the groove in the upper cartridge shaft (Pxt).

Figure 10 (a) shows the upper batlow made in this way.

The drive plate (59) is shown engaged with the groove in the screw shaft (Pxt). Thereafter, by the same operation as in the previous embodiment, the lid (8) of the cartridge chamber (6) is closed, and the drive plate (59) is closed.
) in the direction shown in the figure, the film cartridge (
P) rotates eccentrically from the center (C) of the patrone chamber (6).

As a result, the tip of the film (F) is placed in the cartridge chamber (6).
) while being guided in sliding contact with the inner wall (6A) of the film, and as shown in FIG. 10 (0), reaches the film delivery port (6c). As the film cartridge (P) is further driven and rotated, the leading edge of the film (F) passes through the film delivery port (6) as shown in FIG. 10 (C).
C) and is directed to a film transport mechanism (not shown in FIG. 10(C)).

Figure 12 shows the cartridge (P
) rotation prevention mechanism (R
Another example of 1) is shown.

In this embodiment, the dimensions and shape of the patrone chamber (6) are the same as those shown in FIGS. 10(a) to 10(c). Then, a slit recess (6d) is formed in a part of the inner wall (6A) of the patrone chamber (6).
d) is provided with a locking lever (61).

This locking lever (61) has an active position in which it projects into the cartridge chamber (6), indicated by a solid line in the figure, and a retracted position, in which it retreats outside the cartridge chamber (6), indicated by a two-dot chain line in the figure.
It is rotatably mounted. The rewind lever is configured to move to the operating position when the film rewind operation is set in conjunction with the operation of a rewind lever (not shown) linked to the rewind switch (S6).

During the film rewinding operation, the cartridge shaft (Px) is driven in the direction B in the figure, so that a force acting on the film cartridge (P) itself to rotate it in the direction B in the figure. However, since the locking lever (61) in the operating position comes into contact with the film drawer part (Pa), the film cartridge (1') is prevented from rotating in the direction B in the figure, and the film (F) is It is smoothly rewound into (P).

On the other hand, this locking lever (61) is connected to the cartridge chamber (61) when loading the film (F) or winding the film (F).
6) In the outside retracted position. In addition, this locking lever (61
) should be about [1,0 dragon], and the width of the slit recess (6d) necessary for its entrance and exit is also [1, O+a
m], so it does not interfere with transporting the film (P) in the film loading operation and film winding operation described above.

Note that it is of course possible to apply the configuration in which this locking lever (61) is provided to the patrone chamber (6) in the embodiment shown in FIGS. 5(a) to 5(c).

In each of the embodiments described above, in order to rotate the film cartridge (P) within the cartridge chamber (6), the upper cartridge shaft (Pxt) of the film cartridge (P) is
Although the configuration is shown in which the film (F) is rotationally driven in the direction in which the film (F) is unwound, the lower cartridge shaft (Pxb) on the opposite side may be configured to be driven in the direction in which the film (F) is unwound.

Furthermore, the film (F) is rotated by rotating the cartridge shaft (Px).
Instead of the configuration in which the film cartridge (P) is rotated by unwinding the film (F) and the inner wall of the film cartridge (P), the film cartridge (P) itself can be directly driven to rotate. good. As an example, although not shown, in the embodiment shown in FIG.
Taking advantage of the fact that the elastic layer 1* member (14) is in contact with the lower end surface (Pb) of the film cartridge (P), a disk is provided in place of the rotation prevention plate (13), and this disk is connected to the wire. It is conceivable that the motor (M) be interlocked with the motor (M) via a motor, etc.

FIG. 13 shows yet another embodiment of the patrone chamber (6).

In this embodiment, the cartridge chamber (6) is formed so that most of its inner wall (6A) follows the shape of the outer periphery of the film cartridge (P). In addition, the vicinity of the film outlet (6c) is arranged so that the film drawer part (Pa) of the film cartridge (P) can rotate by a predetermined angle.
It is bulged on the side.

When loading the film (F), place the film cartridge (P) into the cartridge chamber (6) so that the film pull-out part (Pa) is along the contact surface (6Aa), as shown by the two-dot chain line in the figure. insert. Similarly to the embodiment described above, by rotating the cartridge shaft (Px) in the direction A in the figure, the film cartridge (P) also rotates in the direction A in the figure. The leading edge of the film (F) is connected to the film transport roller (
22) and a pressure roller (23). Thereafter, the film (1') is conveyed to the left in the figure by the rotation of the film conveyance roller (22), and the film (1') is conveyed to the left in the figure by the rotation of the film conveyance roller (22).
) and (33) to reach the film exposure section (25
). The position of the film cartridge (P) at this time is indicated by a two-dot chain line in the figure.

In the case of this embodiment, the film (F) coming out from the film drawer part (Pa) before loading is
It is preferable that the length is such that the tip thereof is located near the film transport roller (22) when the film is along the contact surface (6Aa). In this embodiment, the inner wall (6A) of the cartridge chamber (6) is the film cartridge (6A).
Since the shape follows P), it is possible to make the patrone chamber (6) small and compact. Along with this, move the film cartridge (P) to the cartridge room (6).
) The lid (8) for the opening (7) for loading can be made extremely small, for example, as shown by the dashed line in the figure.

Further, according to the configuration of this embodiment, when the film (F) is rewinded, the contact surface (6Aa) prevents the film cartridge (P) from rotating in the direction B in the figure.
The cartridge reversal prevention mechanism (R1) can be omitted.

FIG. 14 shows yet another embodiment of the patrone chamber (6).

In this embodiment, almost the entire inner wall (6A) of the cartridge chamber (6) is formed to follow the shape of the outer periphery of the film cartridge (P), making it even smaller and more compact. In addition, the patrone room (6
) The lid (8) for the opening (7) is formed into a small shape as shown by the two-dot chain line in the figure.

In this embodiment, the pressure roller (23) constituting the film transport mechanism (FT) has the same structure as the embodiment shown in FIGS. 5(a) to 5(c). On the other hand, the film transport roller (22) is supported so as to be movable between a retracted position indicated by a solid line in the figure and an active position indicated by a two-dot chain line.

The film conveyance roller (22) is linked to the opening/closing operation of the lid (8) for the cartridge chamber (6), and the M
When (8) is closed, it moves to the operating position and M
When (8) is open, it is configured to move to the retracted position.

When loading film (F), open the lid (8) and place the film cartridge (P) along the cartridge chamber (6).
Insert. At this time, the film (F) is slightly bent due to its elasticity and restored after passing through the opening (7), so that it is positioned between the film transport roller (22) and the pressure roller (23). Make it. After this, add the lid (8
), the film transport roller (22) moves to the operating position and clamps the film (F), and from then on, the film (F) is moved to the left in the figure by the rotation of the film transport roller (22). transported to.

In the case of this embodiment, there is no need to rotate the film cartridge (P) within the cartridge chamber (6) during the film loading operation. Further, since the film cartridge (P) does not rotate relative to the cartridge chamber (6), there is no need to provide a cartridge reversal prevention mechanism (R1).

Although not shown, a film transport roller (22) and a pressure roller (2) that constitute the film transport mechanism (FT) are also included.
3) between the tip of the film (F) and the Obatrone shaft (
An opening for insertion in the direction along Px) may be provided, and M(8) may also be configured to open and close this opening.

〔Effect of the invention〕

As described above, in the waterproof camera according to the present invention, when loading a film cartridge into the cartridge chamber, the film cartridge is inserted into the cartridge chamber along the axial direction of the cartridge; The area and circumference of the opening can be made smaller than in conventional configurations.

Therefore, by shortening the circumference to be sealed, the probability of deterioration or damage to the sealing member can be reduced, and by making the area of the opening small, the lid for the opening can be made of a small area. This can reduce the occurrence of gaps caused by warping of the lid.

As a result, it has become possible to provide a waterproof camera that has more reliable watertightness for the cartridge room and is less prone to water leakage accidents.
