Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magazine setting mechanism, particularly a magazine that stores a large number of sheets of photosensitive film, coated paper, etc. in a stacked state for feeding them one by one. This invention relates to a mechanism for setting the device into the main body of the device.

2. Description of the Related Art Conventionally, in the field of copying machines and printers, various devices have been known that pick up and feed a large number of sheets stacked in a magazine one by one starting from the topmost sheet. Incidentally, this type of magazine is removably set on a stand of the main body of the apparatus. However, the mechanism for winding up the magazine's light-shielding cover has not yet been installed in the space at the tip of the magazine stand, making it impossible for the operator to access it.
Moreover, when the magazine is fully loaded with sheets, it is too heavy to support by hand, and it is difficult to place the magazine directly in the set position.

Therefore, a setting method can be considered in which the leading end of the magazine is brought into contact with a mounting table and slid forward in an inclined state.

However, in order to reliably attach the light-shielding cover to the magazine, a cushion material is provided on the upper surface of the mounting stand facing the flange of the magazine. When the flange of the magazine is in contact with this cushioning material, it is extremely difficult to adjust the position when setting the magazine.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a magazine setting mechanism that allows a magazine to be easily set on a stand of an apparatus main body without any problems.

Means and Function for Solving the Problems In order to solve the above problems, the magazine setting mechanism according to the present invention includes forming a protrusion having an inclined surface rising in the magazine setting direction on at least either the magazine or the mounting table. The present invention is characterized in that when the magazine is slid in the setting direction on the placing stand, the leading end of the magazine is lifted by the protrusion just before the setting position.

That is, when setting the magazine, the magazine is slid forward in an inclined state with the leading end in contact with the mounting table. The tip of the magazine is lifted by a protrusion just before the set position,
Collision with cushions, etc. that are installed close to the tip of the stand can be avoided.

Embodiment Hereinafter, an embodiment of the magazine setting mechanism (7) according to the present invention will be described based on the accompanying drawings.

FIG. 1 shows the overall configuration of a printer device including a magazine setting mechanism according to the present invention. This printer device 10 mainly includes an electrical box 12, a film magazine 13, a film feeding device 14, a film transporting section 15, an optical unit 16, a sub-scanning unit 18, and a receiver in a main body 11 whose interior is formed into a dark box state. Magazines 19 are arranged as shown.

The magazine 13 is replaceably loaded directly above the electrical equipment box 12, contains unexposed photosensitive film 20 stacked thereon, and has a light-shielding sheet-like cover 41 (second
(see figure) to automatically form openings as necessary.
It is configured to be shielded.

A vacuum-type film feeding device 14 is provided on the magazine 13 to feed the photosensitive films 20 stored therein one by one.

In this feeding device 14, a suction cup holding unit 22 having a vacuum suction cup 21 is attached to the tip of an arm 23, and the vacuum suction cup 21 is oscillated about a support shaft 24 as shown by the arrow while maintaining a horizontal position. The uppermost film 20 is moved to attract the uppermost film 20 and sent between a pair of transport rollers 25a and 25b which are installed at the entrance of the film transport section 15 so as to be able to approach and separate.

Conveyance roller pair 25a, 25b of film conveyance section 15
The upper roller 25a swings around a support shaft 28 so as to be able to come into contact with and separate from the lower roller 25b, and in its open state, the leading edge of a piece of film 20 picked up by the vacuum suction cup 21 is inserted, and then pressure-welded. In this state, the gripped film 20 is sent onto a conveyance guide plate 29. The stopper 32 is installed to be swingable about a support shaft 33 as a fulcrum. The film 20 fed on the conveyance guide plate 29 comes into contact with this stopper 32, its position is regulated, and the film 20 is temporarily stopped. Further, a transport failure of the film 20 is detected by a combination of a film detection sensor SEI and a timer.

The sub-scanning unit 18 includes rotatable upper nip rollers 35a and 35b covered with an elastic member, and a sub-scanning drum 36 that can be rotated counterclockwise in FIG.

The film 20 is moved on the sub-scanning drum 36 by opening the stopper 32, and at this time, the film 20 is image-exposed by a laser beam which can be scanned in the axial direction of the sub-scanning drum 36 from the optical unit 16.

The film 20 thus exposed is discharged into the receive magazine 19. Then, the exposed film 20 housed in the receive magazine 19 is taken out of the printer 10 together with the receive magazine 19 with the receive magazine 19 in a light-shielded state, and is then subjected to development processing. Note that a developing device may be built in at the position of the receive magazine 19, and the exposed film 20 may be sequentially developed and discharged to the outside of the printer device 10.

On the other hand, the host device 1 has been installed adjacent to the present printer device 10. Image information to be printed is communicated from the host device 1 to the printer device 10 one image at a time.

Here, the structure of the magazine 13, particularly the cover winding device, will be explained with reference to FIG. 2.

Magazine 13 that accommodates photosensitive films 20 in a stacked state
The box body is made of light-shielding plastic, and a flange-like flange portion 13g is provided on the top surface.

Adhesive tape is attached to this collar portion 13a.

A light-shielding sheet-like cover 41 is provided on the upper surface of the magazine 13 at the flange 13a so that it can be repeatedly peeled off or pasted with adhesive tape.

The magazine 13 is removably set on the magazine mounting table 39, as will be described in detail below.

This magazine mounting table 39 consists of two bases 4 provided at the front and rear.
It is integrally fixed on 0.40. Further, the base 40, 40 can be pulled out diagonally downward to the right in FIG. 2 from inside the apparatus main body 11 by opening a door (not shown) of the magazine mounting section. Therefore, the magazine 13 is loaded into the main body 11 of the apparatus by pulling out the bases 40, 40.

The cover winding section is for winding up the magazine 130 cover 41, peeling it off, unwinding it, and pasting it. The winding shaft 17 is attached to a support frame 42 that surrounds the magazine 13 and the magazine mounting table 39 at the bottom and on both sides. It is rotatably installed, and also includes a winding motor (not shown) and a gear mechanism 4.
3a and 43b have been installed.

The support frame 42 is a rack in which a pinion 47.47 provided on the support frame 42 is hung on a base 40.40 so that the winding shaft 17 moves horizontally on the flange 13a of the magazine 13. It engages the rack 458° 45a on the retaining plate 45.45.

When winding up the cover 41, a gear 44 rotationally driven by the winding motor engages with the gear mechanism 43a, and the winding shaft 1
7 rotates in the direction of arrow W. As a result of this rotation, the cover 41 whose tip portion has been prevented from being locked onto the winding shaft 17 is sequentially wound around the winding shaft 17, and the support frame 42 moves in the direction of the arrow on the racks 45a, 45a. As a result, the cover 41 is peeled off from the flange 138 of the magazine 13, forming an opening necessary for taking out the film 20 housed inside.

On the other hand, when rewinding the cover 41, the gear 44 is engaged with the gear mechanism 43b to reverse the winding motor. As a result, the pinion 47 is rotated in the direction of arrow rw, and the support frame 42 is moved in the direction of arrow b'. At this time, the winding shaft 17 is in a free state, and the winding shaft 17 is
3a in the direction of the arrow rw length, and the cover 41 wound around the outer periphery is sequentially pasted onto the flange 138. Note that a cushion material 61 is provided on the upper surface of the mounting portion 39a.
is provided.

Since this cushion material 61 is elastically deformed, the mounting portion 39
The cover 41 of the magazine 13 and the flange 13a are brought into close contact between the winding shaft 17 and the winding shaft 17, and reliable shielding is achieved.

Next, the magazine 130 setting mechanism and its setting method will be explained.

As shown in FIGS. 3, 4, and 7, the magazine 13 is provided with a pair of protrusions 50.50 on the back surface of the distal end in the setting direction A. Inclined surfaces 50a, 50a that stand up against the base are formed, and a recess 50b for positioning is formed on the bottom surface.

50b is formed.

On the other hand, as shown in FIG. 5 and FIG.
Positioning protrusions 60, 60 corresponding to 50b are formed. Furthermore, a cushion material 61 is attached to the tip of the mounting table 39, and a notch 62 is formed at the rear end to facilitate attachment and detachment of the magazine 13.

To set the magazine 13 on the mounting table 39, first, with the mounting table 39 pulled out from the main body 11, set the magazine 13 on the mounting table 39.
As shown in Fig. a, the protrusions 50, 50 of the magazine 13 are brought into contact with the bottom plate of the mounting table 39, and the rear surface of the rear end of the magazine 13 is placed on the rear end of the mounting table 39. In this state, magazine 1

The inclined surfaces 50a, 50a are the protrusions 60°6 of the mounting table 39.
0, and the tip of the flange 13a of the magazine 13 is located above the cushion material 61 without colliding with it (see FIG. 8b).

Further, when the magazine 13 is pushed in the setting direction A, the recesses 50b, 50b engage with the protrusions 60, 60, the magazine 13 is completely lowered into the mounting table 39, and the setting is completed (see FIG. 8c). At this time, the tip of the flange 13a of the magazine 13 is completely set on the cushion material 61, and the tip of the cover 41 engages with the winding shaft 17.

When taking out the magazine 13, it is sufficient to lift the rear part of the magazine 13 and move it backward in the direction opposite to the arrow A.

9 to 12 show other embodiments of the magazine setting mechanism.

In FIGS. 9 and 10, the magazine 13 has a front corner portion 53.53 that slightly protrudes laterally, and a recess 54.54 for positioning is formed on the back surface.

Note that a flat bottom plate 55 is placed inside the magazine 13, so that the film 20 can be stored flatly.

As shown in FIGS. 11 and 12, the mounting table 39 has protrusions 63 and 63 having inclined surfaces 63a and 63a formed at the inner tip of the side wall, and a concave portion 54 of the magazine 13 on the bottom plate.
．． Positioning protrusions 64, 64 corresponding to 54 are provided in a protruding manner.

To set this magazine 13 on the mounting table 39, first, the front end of the magazine 13 is brought into contact with the bottom plate of the mounting table 39, and the rear end of the magazine 13 is placed on the mounting table 39. 39 (see Figure 13a). When the magazine 13 is slid in the setting direction A in this state, the front corner part 53.53 becomes the inclined surface 63a,
63a runs onto the protrusion 63.63 (see Figure 13b). When the magazine 13 is pushed in the setting direction A, the front corner portion 53.53 falls between the protrusion 63.63 and the tip side wall, and the recess 54.54 engages with the protrusion 64.64. completes the set (13th c.
(See ward). In this case as well, the tip of the flange 13a is placed on the cushion material 61 without colliding with it.

The operation for taking out the magazine 13 is the same as in the previous embodiment, and it is sufficient to lift the rear part of the magazine 13 and retreat it in the opposite direction to the arrow A.

Note that the magazine setting mechanism according to the present invention is not limited to the above-described embodiments, and can be variously modified within the scope of the gist.

In particular, the engagement relationship between the magazine 13 and the mounting table 39 is as follows:
Various forms other than the relationship between the corner portion 53.53, the recessed portion 54.54 and the protrusion 63.63, and the protrusion 64.64 can be adopted.

Further, the film 20 is available in various sizes, and a dedicated magazine 13 is used for each size.

Regarding the size of the film 20, it is sufficient to provide means for automatically detecting the size of the film 20 when the magazine 13 is loaded into the main body 11. However, the operator may input the size on an operation panel (not shown).

As the means for picking up the film 20, means other than a vacuum suction cup can also be employed.

Furthermore, the sheets that can be stored in the magazine 13 are not limited to photosensitive films, but may also be copy paper, especially coated paper.

As is clear from the above description, according to the present invention, at least either the magazine or the mounting table is formed with a protrusion having an inclined surface rising in the magazine setting direction, and the magazine is placed on the mounting table. When the magazine is slid in the set direction, the tip of the magazine is lifted by the protrusion just before the set position, so that relatively heavy magazines can be easily moved.
The tip can be easily set on the stand without colliding with parts such as cushions.
