Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a photographic device suitable for an automatic ID photographic device and the like, and in particular, has a structure suitable for improving the positioning accuracy of a photosensitive material to an exposed portion.

[0002]

[Prior Art]

 In a conventional device such as an automatic ID photo-taking device, the positioning of the photosensitive material with respect to the exposure part is performed by adjusting the feeding amount of the photosensitive material by a conveyance roller arranged between the paper feeding part and the exposure part. It was done by controlling. Since the feed amount of the photosensitive material by the transport roller is determined by the rotation amount of the transport roller, if the transport roller is driven by a pulse motor, the control pulse to be supplied to the pulse motor can be selected appropriately. The feed amount of the photosensitive material is controlled.

[0003]

[Problems to be solved by the device]

 However, since an ordinary photo-taking device uses a continuous strip of photosensitive material wound in a roll, the conveyor roller is also subject to the load of rotating the rolled photosensitive material. When controlling the pulse motor as described above, it is necessary to execute control that also considers the load due to the photosensitive material, and of course, the photosensitive material is reduced in diameter as it is used and the load increases. Therefore, in order to control the positioning of the photosensitive material to the exposed portion with high accuracy, fine control is required.

Therefore, the conventional photography apparatus has an unsolved problem that the positioning control of the photosensitive material to the exposed portion is complicated and the accuracy is difficult to obtain. The present invention has been made by paying attention to the unsolved problems of the conventional technique, and provides a photographic device suitable for highly accurately controlling the positioning of the photosensitive material to the exposed portion. The purpose is to do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a paper feed unit for containing a continuous photosensitive material, a paper feed unit disposed between the paper feed unit and the exposure unit, and feeding the photosensitive material to the exposure unit. In a photography device having a carrying roller, the carrying roller is rotatable in both forward and reverse directions, and the carrying roller is provided on the side of the paper feeding section of the carrying roller from the exposing section to the photosensitive section. A slack absorbing portion was formed to absorb the slack of the photosensitive material when the material was rotated in the pulling direction.

[0006]

[Action]

 Since the transport roller can rotate in both forward and reverse rotation directions, it is possible to feed the photosensitive material from the paper feeding unit to the exposure unit, or to pull the photosensitive material back from the exposure unit to the paper feeding unit side. And, because a bend absorption part is formed on the paper feed part side of the transport roller, when it is desired to return the light-sensitive material from the exposure part, it is absorbed as a bend immediately upstream of the transport roller without returning it to the paper feed part. it can. Then, even if the conveying roller is rotated in the direction (reverse rotation direction) in which the photosensitive material is pulled back from the exposure section, there is no problem that the photosensitive material is clogged or the photosensitive material is creased.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. First, the configuration will be described. FIG. 1 is a right side view showing a schematic configuration of an automatic ID photo-taking device 1 to which the present invention is applied. An automatic photo-taking device 10 for taking an image of a subject located on the left side of FIG. The automatic developing device 50 is provided below the automatic photographing device 10 and develops the photographic film exposed by the automatic photographing device 10.

As shown in FIG. 2, the automatic image capturing apparatus 10 is provided with a sheet feeding section 11 that accommodates an original roll 12 obtained by winding a continuous strip of photosensitive material in a roll shape. A guide roller 16 and a transport roller 17 for transporting the photosensitive material 15 pulled out from the original roll 12 are disposed between and the exposure unit 20. A cutter 22 that cuts the exposed photosensitive material 15 into a predetermined length is provided downstream of the exposure unit 20, and the cut photographic film is further provided downstream of the cutter 22. A sorting guide 24 for moving to the lower transport path is provided.

Further, at a position where the end of the sorting guide 24 when it is lowered is exposed, a feed roller 26 including three sets of rollers for transporting the photographic film discharged from the sorting guide 24 is disposed. Of the feed rollers 26, the two sets of rollers on the downstream side have narrow vertical intervals when the photographic film is pulled out from the sorting guide 24. As shown in FIG. 3, which is a schematic configuration diagram of the feed roller 26 as viewed from the right side of FIG. 1, a push plate 27 that is displaced along the feed roller 26 is provided, and the push plate 27 is displaced. In doing so, the vertical distance between the two sets of rollers on the downstream side is expanded, and the photographic film sandwiched between these rollers is released from the sandwiched state and pushed by the push-out plate 27 to move to the right.

Further, conveyance rollers 28a, 28b and 28c are arranged on the right side of the feed roller 26, and the photographic film extruded from the feed roller 26 by the extruding plate 27 is provided on the conveyance rollers 28a, 28b and 28c. By 28c, it is sent to the automatic developing device 50 below the automatic photographing device 10. Returning to FIG. 1, two guide plates are vertically opposed to the exposure unit 20 so that the photosensitive material 15 can move between them. On the exposure surface side, the transport path 30 is composed of a transparent glass guide, and two lenses 31A and 31B having different standards are provided above the transport path 30 with their focal points in the transport direction of the transport path 30. They are arranged side by side.

That is, one lens 31A is a lens used when a subject is photographed relatively large, and the other lens 31B is a lens used when a subject is photographed relatively small. Corresponding to these lenses 31A and 31B, shutters 33A and 33B are provided in which only one of them is open at the same time. Therefore, the image of the subject reflected by the mirror 60 is formed on the exposure position 32A of the conveyance path 30 by the lens 31A when the shutter 33A is opened, and is conveyed by the lens 31B when the shutter 33B is opened. It is tied to the exposure position 32B of 30.

Further, sensors 34 and 35 for detecting the photosensitive material 15 passing through the transport path 30 are provided below the start point position and the end point position of the transport path 30 in the exposure unit 20. .. On the other hand, between the guide roller 16 and the transport roller 17, a guide 40 for transporting the photosensitive material 15 and a movable guide 42 are provided.

The movable guide 42 is in a state shown by a solid line in FIG. 2 (hereinafter, referred to as a closed state) that is close to the conveyance roller 17 and a state shown by a broken line in FIG. 2 that is separated from the conveyance roller 17 (hereinafter, an open state). 2), and when the closed state is adopted, the conveyance of the photosensitive material 15 to the exposure section 20 by interposing it between the guide 40 and the conveyance roller 17 is performed. The guide serves as a guide, and when it is in the open state, an accumulator 43 as a deflection absorbing portion is formed on the upstream side of the transport roller 17.

Further, the transport roller 17 is rotatable by an arbitrary rotation amount by a pulse motor (not shown), and has a forward rotation direction (direction in which the photosensitive material 15 is fed from the paper feeding unit 11 side to the exposure unit 20). It is possible to rotate in both the forward and reverse rotational directions (the direction in which the photosensitive material 15 is pulled back from the exposure section 20 to the sheet feeding section 11 side). The pulse motor for driving the conveying roller 17, the movable guide 42, the drive units such as the shutters 33A and 33B, and the movable units are controlled by a controller (not shown) including a microcomputer, an interface circuit, and the like.

FIG. 4 is a flow chart showing an outline of a part of the processing executed by the controller. The operation of this embodiment will be described below with reference to FIG. This process is started by the user of the automatic ID photography device 1 pressing a predetermined selection button after inserting a coin, for example. First, in step 100, the transport roller 17 is rotated in the forward direction to feed the photosensitive material 15 to the exposure section 20. Next, the routine proceeds to step 101, where it is judged whether or not the sensor 34 arranged at the end point position of the transport path 30 has detected the photosensitive material 15, until the sensor 34 detects the photosensitive material 15, that is, The transport roller 17 is continuously rotated in the forward direction until the leading end of the photosensitive material 15 reaches the end point position of the transport path 30.

When it is determined that the sensor 34 has detected the photosensitive material 15 in step 101, the process proceeds to step 102, and the rotation of the carry roller 17 is stopped. Next, in step 103, the movable guide 42 is opened and the accumulator 43 is formed on the upstream side of the transport roller 17. After the accumulator 43 is formed, the process proceeds to step 104, the conveying roller 17 is rotated in the reverse rotation direction, and the photosensitive material 15 is returned to either the exposure position 32A or the exposure position 32B according to the user's selection. ..

In this case, since the photosensitive material 15 is rotated in the direction of pulling it back from the exposure section 20 only by driving the conveying roller 17, the original winding 12 is not rotated, so that there is no load fluctuation related to driving. Therefore, in controlling the pulse motor for rotating the carry roller 17, it is sufficient to consider only the rotation amount of the carry roller 17, which is uniquely determined from the distance from the position of the sensor 34 to the exposure positions 32A and 32B. Since the control contents of the pulse motor are simplified and the feed failure due to the load of the original winding 12 does not occur, the positioning is performed with high accuracy.

Since the accumulator 43 is formed on the upstream side of the transport roller 17, the deflection of the photosensitive material 15 caused by the pullback is absorbed by the accumulator 43. As a result, there is no problem that the pulled back photosensitive material 15 is clogged inside the guide 40 or the photosensitive material 15 has a crease. After the process of step 104 is completed, the process proceeds to step 105, and the shutter 32A or 32B is opened according to the user's selection, and a strobe (not shown) is caused to emit light to perform photographing.

Next, in step 106, the conveying roller 17 is rotated in the forward rotation direction so that the exposed photosensitive material 15 is fed until it is accommodated in the sorting guide 24, and then the process proceeds to step 107, The cutter 22 is operated to cut off the exposed front end portion of the photosensitive material 15. When the photosensitive material 15 is cut, the process proceeds to step 108, and the presence / absence of the next user is determined by, for example, whether or not a coin has been inserted within a predetermined time. When the next user does not exist, the process proceeds to step 109, and the movable roller 42 is kept open, and the transport roller 17 is rotated in the reverse rotation direction. Then, the leading edge of the photosensitive material 15 is returned to the position of the sensor 35, and then the present process is terminated.

The photographic film accommodated in the sorting guide 24 is sent to the feed roller 26 when the sorting guide 24 descends, and from there, through the pushing plate 27 and the conveying rollers 28a, 28b and 28c. The image is sent to the automatic developing device 50 side, and the developing process is performed in the automatic developing device 50. As described above, according to the present embodiment, the positioning of the photosensitive material 15 in the exposure section 20 can be performed with high precision with simple control content, and as a result, the unexposed portion of the peripheral portion of the photographic film can be made extremely small. It will be possible to improve the product value.

In the above embodiments, the case where the photography apparatus according to the present invention is applied to the automatic ID photography apparatus 1 has been described, but the application target of the present invention is not limited to this. For example, it can be applied to a copying machine or the like using photographic technology.

[Effect of the device]

 As described above, according to the present invention, the transport roller that feeds the photosensitive material to the exposure unit can be rotated in both forward and reverse rotation directions, and the slack of the photosensitive material is absorbed by the feeding unit side of the transport roller. Since the slack absorbing portion is formed, the photosensitive material can be positioned with respect to the exposed portion by rotating the conveying roller in the reverse rotation direction, and therefore control can be performed without considering the load of the photosensitive material. Since the slack absorbing section absorbs the slack of the photosensitive material, the photosensitive material is not clogged, and the photosensitive material does not have a crease.
