The ejection mechanism has a claw member that enters the instant film pack case and ejects the instant film from the outlet. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-246021 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned printer device or camera with printer, when the claw member feeds the instant film from the discharge port, the tip side of the instant film may get stuck, for example, if the rotation speed of the transport roller is low and the rotation load is large. If the tip side of the instant film gets stuck, the base end of the instant film will be subjected to a compressive force by the claw member. Since instant film is a thin sheet, its thickness is very small compared to the length from the tip to the base end. Therefore, if the tip side of such instant film gets stuck and a compressive force is applied from the base end side, the instant film may buckle.

[0005] SUMMARY OF THE PRESENT DISCLOSURE The present invention has been made to solve the above problems, and has as its object to provide a printer apparatus and a camera with a printer that can prevent buckling of the recording medium when it is fed out. [Means for solving the problem]

[0006] In order to solve the above problems, the printer device of the present invention includes a loading chamber, a slit, a claw member, and a loading chamber side rib, the loading chamber side rib being formed at a position and protruding amount that allows it to be inserted into a recording medium pack loaded in the loading chamber, the loading chamber being loaded with a recording medium pack including at least a sheet-shaped recording medium and a case that stores the recording media in a stack and has a feed opening formed therein for feeding the recording media. The slit is formed in the loading chamber and cuts out a part of the loading chamber inner surface that faces the recording media. The claw member enters the inside of the case through the slit and feeds the recording medium from the feed opening. The loading chamber side rib is provided so as to protrude from the loading chamber inner surface along the slit.

[0007] It is preferable that the tip of the loading chamber side rib facing the recording medium is positioned so that it can support the recording medium inside the case together with the film pack side rib provided inside the case, and it is preferable that it is positioned so that the claw member passes between it and the film pack side rib.

[0008] It is preferable that the case has a notch through which the claw member passes when feeding out the recording medium, the film pack side rib is arranged along the notch, and the loading chamber side rib is arranged in a position that enters inside the notch when the recording medium pack is loaded into the loading chamber.

[0009] It is preferable that the loading chamber side rib has a flat surface at the tip side facing the recording medium, and that when a recording medium pack is loaded into the loading chamber, the rib is a rectangular prism arranged parallel to the film pack side rib.

[0010] The recording medium is preferably a mono-sheet type instant film. The loading chamber has an exposure opening for exposing the recording medium in the case to subject light, and the loading chamber side rib is preferably disposed along one side of the exposure opening.

[0011] A camera with a printer according to the present invention comprises the above-mentioned printer device, and an imaging unit having an imaging optical system, which captures an image of a subject and outputs image data to the printer device.

[0012] A camera with a printer according to the present invention comprises the above-mentioned printer device and an imaging optical system that exposes an image of a subject onto an instant film in a case through an exposure aperture. Effect of the Invention

[0013] According to the present invention, it is possible to prevent the recording medium from buckling when the recording medium is fed out. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] [First embodiment] [Outline of the camera with printer] 1, a camera with a printer 10 of the present invention comprises a camera body 11, an imaging unit 12, and a printer section 13. An imaging window 15 and two release switches 16A, 16B are provided on the front of the camera body 11. The imaging window 15 is disposed in the center of the front of the camera body 11. The imaging window 15 exposes an imaging optical system 19 (see FIG. 2) that constitutes the imaging unit 12.

[0016] The camera body 11 has a substantially square shape when viewed from the front. The printer-equipped camera 10 uses instant film 28 (see FIG. 10) as a sheet-like recording medium. The instant film 28 is a wide-format instant film whose width is longer than its transport direction.

[0017] 2, the imaging unit 12 is provided with an imaging optical system 19 and a solid-state imaging element 20. The solid-state imaging element 20 is, for example, a CMOS (Complementary Metal Oxide Semiconductor) type image sensor, and has a light receiving surface configured with a plurality of pixels (not shown) arranged in a two-dimensional matrix. Each pixel includes a photoelectric conversion element, and performs photoelectric conversion on the subject image formed on the light receiving surface by the imaging optical system 19 to generate an imaging signal.

[0018] The solid-state imaging element 20 includes signal processing circuits (none of which are shown) such as a noise removal circuit, an auto-gain controller, and an A / D conversion circuit. The noise removal circuit performs noise removal processing on the imaging signal. The auto-gain controller amplifies the level of the imaging signal to an optimal value. The A / D conversion circuit converts the imaging signal into a digital signal and outputs it from the solid-state imaging element 20 to an internal memory (not shown). The output signal from the solid-state imaging element 20 is image data (so-called RAW data) having one color signal for each pixel.

[0019] Pressing at least one of the release switches 16A, 16B drives the solid-state imaging element 20 to capture an image of the subject. A film ejection opening 21 is provided on the top surface of the camera body 11. Instant film 28 with printed images is ejected from the film ejection opening 21.

[0020] As shown in Fig. 3, the loading lid 22 is attached to the rear side of the camera body 11 by a hinge portion 22e. The hinge portion 22e supports the loading lid 22 so that it can rotate between an open position (the state shown in Fig. 4) and a closed position (the state shown in Fig. 3). Note that a locking mechanism and an unlocking mechanism (not shown) are provided between the camera body 11 and the loading lid 22. The locking mechanism holds the loading lid 22 in the closed position, and when the unlocking mechanism is operated, the loading lid 22 rotates from the closed position to the open position.

[0021] 4, an instant film pack 24 (recording medium pack) containing instant film 28 is loaded into the loading chamber 23. The loading lid 22 has a plurality of film pressing portions 22a to 22d provided on its inner surface.

[0022] A rear display unit 17 and an operation unit 18 are provided on the outer surface of the loading lid 22, i.e., on the rear surface of the camera body 11. The rear display unit 17 is composed of, for example, an LCD (Liquid Crystal Display) panel. One frame of image data output from the solid-state imaging element 20 is sequentially input to the rear display unit 17 and displayed as a through image.

[0023] When the photographer presses at least one of the release switches 16A and 16B, shooting begins. During shooting, image data is acquired from the solid-state imaging element 20. This image data is subjected to known image processing by an image processing unit (not shown) and then compressed. Image processing includes, for example, matrix calculation, demosaic processing, gamma correction, luminance conversion, color difference conversion, and resizing. The image data that has been processed and compressed is recorded in an internal memory (not shown), such as a flash memory, provided in the camera body 11.

[0024] When the menu switch 18a of the operation unit 18 is pressed, an image is reproduced and displayed on the rear display unit 17 based on the image data recorded in the built-in memory. When an image to be printed is displayed on the rear display unit 17, the photographer can press the print switch 18b of the operation unit 18 to start the print process by the printer unit 13.

[0025] [Instant film pack composition] As shown in FIGS. 5 and 6, the instant film pack 24 includes a case 26, a film pressure plate 27, a plurality of instant films 28, and a film cover 30.

[0026] 6, case 26 stores a stack of multiple instant films 28 and one film cover 30. Case 26 is made of a material such as thermoplastic resin or paper resin made by mixing thermoplastic resin with cellulose. Case 26 is made of a box-shaped case member 31 and a lid 32 that covers an opening formed on the back side of case member 31.

[0027] As shown in FIG. 7, the case member 31 is formed with an exposure opening 31a for exposing the instant film 28. In the following description, the surface of the instant film pack 24 on which the exposure opening 31a is formed is referred to as the "front surface," the surface opposite the "front surface" is referred to as the "rear surface," the surface facing the film discharge port 21 of the camera body 11 is referred to as the "top surface," and the surface opposite the "top surface" is referred to as the "bottom surface." In the case member 31, the film cover 30 is placed in front of the foremost instant film 28 that is set first in the exposure opening 31a. This causes the exposure opening 31a to be light-tightly blocked by the film cover 30. In addition, a notch 31b is provided at the bottom of the exposure opening 31a into which a well-known claw member 57 (see FIGS. 11, 12, and 13) provided on the camera is inserted. The notch 31b is a linear notch through which the claw member 57 passes when feeding out the instant film 28 or the film cover 30. The notch 31 b is connected from the lower portion of the exposure opening 31 a to the bottom surface of the case member 31 .

[0028] A feed opening 31c is formed on the top surface of the case member 31. The feed opening 31c is formed in a slit shape. The instant films 28 or film covers 30 are fed out of the instant film pack 24 one by one from the feed opening 31c by a claw member 57 inserted into the notch 31b of the case member 31.

[0029] A light-shielding seal 31d is attached to the case member 31 so as to block the outlet 31c from the outside. The light-shielding seal 31d is formed in a flexible sheet shape. The light-shielding seal 31d is attached only to one edge of the long side of the outlet 31c so as not to interfere with the instant film 28 or the film cover 30 passing through the outlet 31c.

[0030] 8, a film pack rib 31e is provided on the rear side of the front surface of the case member 31. The film pack rib 31e is arranged along the cutout 31b, and protrudes from the rear side of the front surface of the case member 31 to the rear side.

[0031] 9, the film pack rib 31e is formed in a straight line, similar to the notch 31b. Specifically, the film pack rib 31e is a rectangular prism-shaped rib arranged parallel to the notch 31b. As described above, the notch 31b is connected to the exposure opening 31a, so the film pack rib 31e formed along the notch 31b is in contact with the exposure opening 31a.

[0032] 7, the cover 32 has a pair of openings 32a, a pair of unit support projections 32b, a pair of rivet pins 32c, and a support piece 32d. The pair of openings 32a are formed vertically at a predetermined distance apart, and serve as an entrance through which the film pressing portion 22a provided on the printer-equipped camera 10 fits when the film is loaded into the printer-equipped camera 10.

[0033] The pair of unit support protrusions 32b are provided vertically on both side edges of the lid 32, and have an arc shape with the center protruding toward the exposure opening 31a. The unit support protrusions 32b come into contact with both side edges of the back surface of the last layer of instant film 28, and push up the instant film 28 in an arc shape with the center protruding toward the exposure opening 31a. This prevents a gap from being created between the film cover 30 and the exposure opening 31a.

[0034] The pair of rivet pins 32c are for attaching the film pressure plate 27. The support piece 32d supports the center portion of the last layer of instant film 28 from behind, preventing the center portion of the instant film 28 from bending in a direction curving toward the lid 32.

[0035] The film pressing plate 27 is made of two sheets 27a and 27b made of elastic synthetic resin. When the loading lid 22 is closed, the sheet 27a is pressed by the multiple film pressing parts 22a and curves so as to be convex toward the lid 32. The sheet 27a is formed with an opening 27c and a pair of holes 27d. The opening 27c is formed vertically in the center of the sheet 27a and is for inserting the support piece 32d. A pair of rivet pins 32c are inserted into the pair of holes 27d and are used to attach the film pressing plate 27 to the lid 32.

[0036] The sheet 27b has an opening 27e and a pair of holes 27f. The opening 27e is formed in the center of the sheet 27a and is for inserting the support piece 32d. A pair of rivet pins 32c are inserted into the pair of holes 27f. The sheet 27b has a lower end 27h attached to a lower end 27g of the sheet 27a. This prevents the sheet 27a from sagging and prevents light leakage from the pair of openings 32a, and pushes up the instant film 28 in a substantially flat manner when the sheet 27a is elastically bent by the multiple film pressing parts 22a. As a result, the frontmost film cover 30 or the instant film 28 is pressed against the rear side of the front surface of the case member 31.

[0037] Both side surfaces 24a, 24b of the instant film pack 24 come into contact with positioning protrusions 23h of the loading chamber 23, which will be described later. The instant film pack 24 has a protrusion 24d (see Figures 8 and 9) on its bottom surface 24c to prevent reverse loading. The protrusion 24d is disposed at a position close to one side surface 24a with respect to the center line of the instant film pack 24 in the width direction X. The protrusion 24d is formed integrally with the case member 31 of the instant film pack 24. The protrusion 24d is formed in a rectangular parallelepiped shape protruding from the bottom surface 24c of the instant film pack 24.

[0038] [Instant film composition] As shown in Fig. 10, the instant film 28 is composed of a mask sheet 33, a photosensitive sheet 34, a cover sheet 35, a developer pod 36, and a trap section 37, and is a so-called mono-sheet type film. The mask sheet 33 is formed in a sheet shape from a thin synthetic resin and has a screen opening 33a. The photosensitive sheet 34 is provided with a photosensitive layer, a diffuse reflection layer, an image receiving layer, etc. The cover sheet 35 has an exposure surface 28a that faces the exposure head 50 described later.

[0039] The developer pod 36 is formed in a substantially bag-like shape and contains developer 38. The developer pod 36 is attached to the end of the photosensitive sheet 34 on the outlet 31c side, and is wrapped with the end of the mask sheet 33. The trap portion 37 is attached to the end of the photosensitive sheet 34 on the opposite side to the outlet 31c side, and is similarly wrapped with the end of the mask sheet 33.

[0040] When printing, the instant film 28 is exposed to printing light by irradiating the photosensitive layer. When developing, the developer pod 36 is torn open and developer 38 is poured into the gap 39 between the photosensitive sheet 34 and the cover sheet 35 and developed. The image formed by the exposure of the photosensitive layer is inverted by the diffuse reflection layer and transferred to the image receiving layer. Thus, a positive image appears on the positive image observation surface 40 of the photosensitive sheet 34 exposed through the screen opening 33a.

[0041] The film cover 30 is formed in a sheet shape that is thinner than the instant film 28, and has light-blocking properties and flexibility. The film cover 30 is a synthetic resin molded product, and is formed, for example, from polystyrene containing carbon black. In other words, the film cover 30 has higher rigidity than the instant film 28. When the instant film pack 24 is loaded into the loading chamber 23 for use, the film cover 30 is discharged to the film discharge port 21 by a pair of spreading rollers 54 (see Figures 11 and 12), which will be described later.

[0042] [Printer section configuration] As shown in Figures 11 and 12, the printer unit 13 is composed of an exposure head 50, a film support member 51, a roller drive mechanism 52, a pair of conveying rollers 53, a pair of unfolding rollers 54, an unfolding control member 55, a device housing 56 (see Figure 13), a claw member 57, a claw member drive mechanism 58, and a control unit 59.

[0043] In Figure 12, to avoid complexity, the device housing 56 and other components are not shown, but in reality, the printer unit 13 is formed by attaching the exposure head 50, film support member 51, roller drive mechanism 52, conveying roller pair 53, unfolding roller pair 54, unfolding control member 55, claw member 57, and claw member drive mechanism 58 to the device housing 56.

[0044] In the following description, the conveying direction in which the conveying roller pair 53 conveys the instant film 28 is defined as the Y direction, the width direction of the instant film 28 perpendicular to the Y direction is defined as the X direction, and the direction perpendicular to the X and Y directions is defined as the Z direction.

[0045] As shown in Fig. 13, the device housing 56 is formed in a box shape with the rear side of the camera body 11 open, and is provided integrally with the loading chamber 23. In addition to the loading chamber 23, the device housing 56 has a frame portion that supports the exposure head 50, the roller drive mechanism 52, the transport roller pair 53, the spreading roller pair 54, the claw member 57, etc., but these are omitted in Fig. 13. The device housing 56 is formed from a resin material.

[0046] As described above, the instant film pack 24 is loaded into the loading chamber 23. An image is recorded by the printer unit 13 on the instant film 28 ejected from the instant film pack 24. The shape of the loading chamber 23 and the like will be described later.

[0047] [Configuration of the conveying roller pair and the spreading roller pair] The pair of conveying rollers 53 and the pair of spreading rollers 54 are supported by bearings (not shown) provided in the device housing 56. The pair of conveying rollers 53 and the pair of spreading rollers 54 are rotationally driven by a roller drive mechanism 52 to convey the film cover 30 and the instant film 28. The roller drive mechanism 52 includes, for example, a motor serving as a drive source, and a drive transmission gear train that transmits the rotational drive force.

[0048] The transport roller pair 53 is composed of a capstan roller 61 and a pinch roller 62. The capstan roller 61 and the pinch roller 62 are disposed in positions that sandwich the transport path of the instant film 28 (see FIG. 11). The capstan roller 61 is composed of a pair of cylindrical spike roller members 61a, a drive gear 61b, and a rotating shaft 61c that holds the spike roller members 61a and the drive gear 61b.

[0049] The pinch roller 62 is composed of a roller member 62a, a drive gear 62b, and a rotating shaft 62c. The drive gears 61b, 62b are provided at both ends of the rotating shafts 61c, 62c, and mesh with each other. One end of the rotating shaft 61c is connected to a motor via a drive transmission gear train. Therefore, when the motor rotates, the capstan roller 61 and the pinch roller 62 are rotated in synchronization. The instant film 28 discharged from the instant film pack 24 is transported by the transport roller pair 53 toward the spreading roller pair 54.

[0050] The spreading roller pair 54 is composed of spreading rollers 63, 64, and is disposed downstream in the transport direction relative to the transport roller pair 53. The spreading roller 63 is disposed on the side facing the exposure surface 28a of the instant film 28. The spreading roller 64 is disposed on the side facing the image observation surface 40 of the instant film 28. A motor is connected to one end of the spreading rollers 63, 64 via a drive transmission gear train. Therefore, when the DC motor rotates, the spreading rollers 63, 64 rotate synchronously.

[0051] The spreading roller pair 54 holds the instant film 28 conveyed by the conveying roller pair 53 over the entire width and conveys it to the film discharge opening 21. The developer pod 36 of the instant film 28 is crushed by being held by the spreading roller pair 54. As a result, the developer is spread in the gap 39 (see FIG. 10).

[0052] A development control member 55 (see FIG. 11) is provided between the transport roller pair 53 and the development roller pair 54. The development control member 55 comes into contact with the positive image observation surface 40 of the instant film 28 that has been transported, and controls the distribution of the developing solution during development by rubbing the positive image observation surface 40 of the instant film 28. The development control member 55 is fixed to the device housing 56 via a support member (not shown).

[0053] The transport roller pair 53 transports the instant film 28, which has been sent out from the instant film pack 24 by the claw member 57, toward the film outlet 21. Note that an exposure position P (see FIG. 11) where the exposure head 50 exposes the instant film 28 to printing light is located between the outlet 31c of the instant film pack 24 and the transport roller pair 53. Then, exposure by the exposure head 50 is performed during transport by the transport roller pair 53.

[0054] The control unit 59 controls the exposure of the exposure head 50 based on the image data. Exposure by the exposure head 50 is performed by moving the instant film 28 line by line and sequentially exposing the line images onto the instant film 28. In this way, one screen's worth of image is exposed onto the photosensitive layer of the instant film 28. The instant film 28 is then transported by the transport roller pair 53 toward the spreading roller pair 54.

[0055] [Film holding section configuration] When the loading lid 22 is in the open position, the loading chamber 23 is opened (the state shown in FIG. 4), and when the loading lid 22 is in the closed position, the loading lid 22 covers the open back surface of the loading chamber 23 (the state shown in FIG. 3). The instant film pack 24 is positioned in the X and Y directions relative to the loading chamber 23, and is further positioned in the Z direction by placing the loading lid 22 in the closed position. Specifically, a plurality of film pressing portions 22a to 22d provided on the loading lid 22 position the instant film pack 24 in the Z direction.

[0056] When the instant film pack 24 is loaded into the loading chamber 23 and the loading lid 22 is in the closed position, the film pressing portions 22a to 22d enter the inside of the instant film pack 24 through the opening 32a and press the film pressing plate 27 (see FIG. 17). As a result, the instant film 28 in the instant film pack 24 is pressed in the stacking direction.

[0057] [ Loading Room configuration] 13, the loading chamber 23 has side surfaces 23a, 23b, a top surface 23c, a bottom surface 23d, a front surface 23e (loading chamber inner surface), a slit 23f, and a loading chamber side rib 23g. When the instant film pack 24 is loaded into the loading chamber 23, the front surface 23e of the loading chamber 23 faces the instant film 28 stored in the instant film pack 24. The slit 23f is formed by cutting out a part of the front surface 23e. The above-mentioned claw member 57 enters the inside of the case 26 through the slit 23f and sends out the instant films 28 one by one to the outside of the instant film pack 24.

[0058] The tip 57a of the claw member 57 is a hook bent into a C-shape (see FIG. 11), and this tip 57a engages with and presses the base end of the instant film 28. The claw member 57 is driven to move linearly and rotate by a claw member drive mechanism 58. The claw member drive mechanism 58 is a well-known configuration made up of a motor and a drive transmission gear train.

[0059] As shown in Fig. 14, the loading chamber side rib 23g is provided to protrude from the front surface 23e along the slit 23f. As shown in Fig. 15, the loading chamber side rib 23g is formed at a position and with a protruding amount that allows it to be inserted into the instant film pack 24 loaded in the loading chamber 23. Note that in Fig. 15, to avoid complication, only the case member 31 of the instant film pack 24 loaded in the loading chamber 23 is shown.

[0060] The loading chamber side rib 23g is disposed in a position that enters the inside of the notch 31b of the instant film pack 24 when the instant film pack 24 is loaded into the loading chamber 23. As a result, the loading chamber side rib 23g is disposed in a position where it can support the instant film 28 in the case 26 together with the film pack side rib 31e (see FIG. 17).

[0061] 16, the loading chamber rib 23g is disposed at a position where the claw member 57 passes between the loading chamber rib 23g and the film pack rib 31e. The claw member 57 passes between the loading chamber rib 23g and the film pack rib 31e, and feeds the instant films 28 out of the instant film pack 24 one by one.

[0062] The loading chamber side rib 23g has a flat surface at the tip side that faces the instant film 28 when the instant film pack 24 is loaded into the loading chamber 23, and is a square pillar-shaped member disposed parallel to the film pack side rib 31e.

[0063] Further, a positioning protrusion 23h is provided in the loading chamber 23. The positioning protrusion 23h comes into contact with both side surfaces 24a, 24b of the instant film pack 24, so that the instant film pack 24 can be positioned in the X direction.

[0064] In addition, an elastic member 23i is provided on the bottom surface 23d of the loading chamber 23. An elastic force acts when the elastic member 23i returns from a compressed state to an uncompressed state, and the top surface 24e of the instant film pack 24 is pressed against the top surface 23c of the loading chamber 23. This allows the instant film pack 24 to be positioned in the Y direction. The top surface 23c of the loading chamber 23 has an opening that leads to the transport roller pair 53.

[0065] Furthermore, a reverse loading prevention notch 23j is formed in the bottom surface 23d of the loading chamber 23. The reverse loading prevention notch 23j fits into a protrusion 24d of the instant film pack 24 (as shown in FIG. 15), thereby preventing the instant film pack 24 from being loaded in the reverse direction.

[0066] The instant film pack 24 is positioned in the X and Y directions relative to the loading chamber 23, and is further positioned in the Z direction by closing the loading lid 22. Specifically, the film pressing parts 22a to 22d provided on the loading lid 22 enter the inside of the instant film pack 24 through the opening 32a and press the film pressing plate 27, stomach The instant film pack 24 is positioned in the Z direction.

[0067] [Function of the loading chamber side rib] As described above, the camera with printer 10 is provided with the loading chamber 23 having the loading chamber side rib 23g that protrudes along the slit 23f and is formed at a position and protruding amount that allows insertion into the instant film pack 24. As a result, when the instant film pack 24 is loaded into the loading chamber 23, the loading chamber side rib 23g supports the instant film 28.

[0068] For example, immediately after the pair of transport rollers 53 starts to rotate, if there is a large rotational load, or if the operation of the claw member 57 and the operation of the pair of transport rollers 53 are not synchronized, the tip of the instant film 28 may get caught. If the tip of the instant film 28 gets caught, the base end of the instant film will be subjected to a compressive force by the claw member 57. If there were no loading chamber side rib 23g, as in conventional printer devices, there would be no support around the position where the claw member passes, and the instant film subjected to the compressive force would buckle, possibly resulting in wrinkles, etc.

[0069] In contrast, in this embodiment, the loading chamber 23 is provided with the loading chamber rib 23g as described above. Therefore, as shown in FIG. 17, when the instant film pack 24 is loaded into the loading chamber 23, the loading chamber rib 23g supports the instant film 28. In FIG. 17, the film cover 30 has already been sent out from the delivery opening 31c and discharged from the film discharge opening 21. In FIG. 17, the instant film 28 is not shown to avoid complication, but in reality, a plurality of instant films 28 are stacked between the exposure opening 31a and the film pressing plate 27. In FIG. 17, the claw member drive mechanism 58 located around the claw member 57 is not shown, but in reality, the claw member drive mechanism 58, which is composed of a gear train or the like, is installed in front of the loading chamber 23.

[0070] Since the loading chamber rib 23g protrudes along the slit 23f, the claw member 57 passes through a position immediately adjacent to the loading chamber rib 23g. That is, since the position immediately adjacent to where the claw member 57 passes is supported by the loading chamber rib 23g, the instant film 28 is unlikely to buckle even if it receives a compressive force from the claw member 57.

[0071] 18, when the instant film pack 24 is loaded into the loading chamber 23, the instant film 28 is supported by the loading chamber rib 23g, and is therefore likely to bend linearly in the Y direction and into a U-shaped curved surface that is convex in the Z direction. Note that, as described above, the instant film 28 is pressed in the Z direction by the film pressing portions 22a-22d, and is therefore bent so as to be convex toward the exposure opening 31a. This bending increases the rigidity in the Y and Z directions, and therefore buckling of the instant film 28 can be prevented even if it is subjected to a compressive force from the claw member 57, i.e., a compressive force along the Y direction.

[0072] Furthermore, in this embodiment, the loading chamber rib 23g is disposed in a position where it can support the instant film 28 in the case 26 together with the film pack rib 31e. This ensures that the instant film 28 is reliably supported by the loading chamber rib 23g and the film pack rib 31e at a position immediately adjacent to where the claw member 57 passes. Furthermore, by supporting the instant film 28 with two ribs, flatness is maintained. This makes it even more difficult for buckling caused by the claw member 57 to occur.

[0073] Furthermore, the loading chamber rib 23g has a flat surface at the tip end that faces the instant film 28 when the instant film pack 24 is loaded into the loading chamber 23, and is a square prism disposed parallel to the film pack rib 31e. This increases the contact area between the loading chamber rib 23g and the instant film 28. This makes it possible to more reliably support the instant film 28, making it even less likely that buckling will occur due to the claw member 57.

[0074] [Second embodiment] In the first embodiment, the present invention is applied to a digital camera with a printer. Appointment However, the present invention is not limited to this, and may also be applied to an analog type camera with printer, as shown in Fig. 19. Note that parts and members similar to those of the camera with printer 10 of the first embodiment are given the same reference numerals and descriptions thereof will be omitted.

[0075] The camera with printer 100 comprises a camera body 101, an imaging optical system 102, and a printer unit 103. An imaging window 104 and a release switch (not shown) are provided on the front of the camera body 101. The imaging window 104 is 0 1. The imaging window 104 exposes the imaging optical system 102. The imaging optical system 102 is provided with a shutter device (not shown), which opens and closes in response to the pressing of a release switch.

[0076] The camera with printer 100 uses instant film 28, similar to the camera with printer 10 of the first embodiment. The printer unit 103 is equipped with a loading chamber 105. An instant film pack 24 (recording medium pack) containing the instant film 28 is loaded into the loading chamber 105.

[0077] The loading chamber 105 is formed in a box shape with an open back side, similar to the loading chamber 23 provided in the camera with printer 10 of the first embodiment described above, and when the loading lid 22 is in the open position, the loading chamber 105 is opened, and when the loading lid 22 is in the closed position, the loading lid 22 covers the open back side of the loading chamber 105.

[0078] As shown in Fig. 20, a slit 105b is provided on one side surface 105a (the inner surface of the loading chamber) of the loading chamber 105. Although not shown, in the camera with printer 100, a claw member driving mechanism 58 is incorporated on the side of the loading chamber 105 rather than in front of it. The claw member 57 is provided integrally with a connecting member 106. The connecting member 106 is connected to the claw member driving mechanism 58 through the slit 105b, and transmits the drive of the claw member driving mechanism 58 to the claw member 57.

[0079] Since the printer-attached camera 100 is an analog camera, an exposure opening 110 is provided in the loading chamber 105. The exposure opening 110 is formed by cutting out a square shape from the front surface 105c of the loading chamber 105. A dark box portion 111 (see FIG. 19) is provided in front of the loading chamber 105. The dark box portion 111 communicates with the exposure opening 110. The imaging optical system 102 is held in front of the dark box portion 111. When the shutter device is opened or closed, the imaging optical system 102 exposes an image of a subject onto the instant film 28 in the case 26 through the exposure opening 110.

[0080] As in the camera with printer of the first embodiment, the claw member 57 is provided at a position that allows it to enter the inside of the case 26 through the slit 105b, and feeds the instant films 28 out of the instant film pack 24 one by one.

[0081] The loading chamber rib 105d is provided to protrude from the front surface 105c along the slit 105b, similar to the loading chamber rib 23g in the first embodiment. The loading chamber rib 23g is disposed along one side of the exposure opening 110. The loading chamber rib 105d is disposed at a position more inward than the claw member 57.

[0082] As shown in Fig. 21, the loading chamber side rib 105d is formed at a position and with a protruding amount that allows it to be inserted into the instant film pack 24 loaded in the loading chamber 105. In Fig. 21, to avoid complication, only the case member 31 of the instant film pack 24 loaded in the loading chamber 105 is shown.

[0083] As with the printer-equipped camera 10 of the first embodiment, the loading chamber rib 105d is disposed in a position that enters the notch 31b of the instant film pack 24 when the instant film pack 24 is loaded into the loading chamber 105. As a result, the loading chamber rib 105d is disposed in a position that allows it to support the instant film 28 in the instant film pack 24 together with the film pack rib 31e.

[0084] The loading chamber rib 105d is disposed at a position where the claw member 57 passes between the loading chamber rib 105d and the film pack rib 31e. That is, the claw member 57 passes between the loading chamber rib 105d and the film pack rib 31e to send out the instant films 28 one by one to the outside of the instant film pack 24. The loading chamber rib 105d has a flat surface at the tip side that faces the instant films 28 when the instant film pack 24 is loaded into the loading chamber 105, and is a square pillar disposed parallel to the film pack rib 31e.

[0085] As described above, the camera with printer 100 is provided with the loading chamber 105 having the loading chamber side rib 105d that protrudes along the slit 105b and is formed at a position and protruding amount that allows the instant film pack 24 to be inserted into the instant film pack 24. As a result, just like the camera with printer 10 of the first embodiment, when the instant film 28 is fed out, the instant film 28 is supported by the loading chamber side rib 105d, so that buckling is unlikely to occur even when a compressive force is applied from the claw member 57.

[0086] Furthermore, this embodiment is applied to an analog camera with printer 100, and an exposure opening 110 is provided in the loading chamber 105. Therefore, when the instant film 28 is fed out, there is nothing to support the portion of the instant film 28 facing the exposure opening 110. In other words, the portion of the instant film 28 facing the exposure opening 110 is susceptible to compressive forces, but in this embodiment, a loading chamber side rib 105d is provided to support the instant film 28, thereby preventing buckling.

[0087] In each of the above embodiments, one loading chamber side rib 23g, 105d is provided for the loading chamber 23, 105, but the present invention is not limited to this, and any shape and arrangement may be used as long as it is capable of supporting the instant film 28. For example, as shown in Fig. 22, a plurality of discontinuous loading chamber side ribs 23g, 105d may be arranged in a row. Furthermore, the shape of the loading chamber side ribs 23g, 105d is not limited to a quadrangular prism, and may be a triangular prism, semi-cylinder, or the like.

[0088] In the above embodiments, mono-sheet type instant film is exemplified as a sheet-like recording medium, but the present invention is not limited to this and any recording medium that is stacked and stored in a case may be used, such as thermal paper or inkjet paper. If the recording medium is thermal paper, the printer will be a thermal printer, and if the recording medium is inkjet paper, the printer will be an inkjet printer. In addition, in the above embodiments, an example in which the present invention is applied to a camera with a printer will be described. Appointment However, the present invention is not limited to this and may be applied to a printer device alone.

[0089] In the above embodiment, the hardware structure of a processing unit that executes various processes such as the control unit 59 is various processors as shown below. The various processors include a CPU (Central Processing Unit), which is a general-purpose processor that executes software (programs) and functions as various processing units, a GPU (Graphical Processing Unit), a programmable logic device (PLD), which is a processor whose circuit configuration can be changed after manufacture such as an FPGA (Field Programmable Gate Array), and a dedicated electric circuit, which is a processor having a circuit configuration designed exclusively for executing various processes.

[0090] One processing unit may be configured with one of these various processors, or may be configured with a combination of two or more processors of the same type or different types (for example, multiple FPGAs, a combination of a CPU and an FPGA, or a combination of a CPU and a GPU, etc.). Also, multiple processing units may be configured with one processor. As an example of configuring multiple processing units with one processor, first, as represented by a computer such as a client or a server, there is a form in which one processor is configured with a combination of one or more CPUs and software, and this processor functions as multiple processing units. Second, as represented by a system on chip (SoC), there is a form in which a processor is used that realizes the functions of the entire system including multiple processing units with one IC (Integrated Circuit) chip. In this way, the various processing units are configured using one or more of the above various processors as a hardware structure.

[0091] Furthermore, the hardware structure of these various processors is, more specifically, an electric circuit in the form of a combination of circuit elements such as semiconductor elements. [Explanation of symbols]
