Abstract

PURPOSE:To make it possible to place a negative film, besides in transverse direction, in longitudinal direction to an operator,nd to feed in longitudinal direction and perform printing of a photograph efficiently by making no obstacle exists in not only transverse direction but also in the area of longitudinal direction of a negative film placing section on a table. CONSTITUTION:A negative film holding member 3 is so made that it can be placed with its negative film insertion hole 31 facing transverse direction or facing longitudinal direction. In concrete terms, a rectangular hole 21 is formed on a table, and at the same time, the tubular body 51 of a projection lens unit 50 is made to rectangular tubular form that fits to the hole 21, and a negative film holding member 3 is made to have outlines larger than the hole 21. Thus, the tubular body 51 of the projection lens unit 50 is dropped in the hole 21, and the negative film holding member 3 is held by fitting it to the outer peripheral edge of the hole 21. The projection lens unit 50 is taken out, and after turning it by 90 deg.C, inserted again to the hole 21. Consequently, a negative film can be held by the negative film holding member 3 to make the direction of the negative film face either in transverse direction or longitudinal direction.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a photographic printing machine.

[Prior art]

An outline of a conventional photoprinting machine is shown in Fig. 4. 1 is an outer box, 2
3 is a horizontal table, 3 is a negative holding member provided in the negative placement section, and 4 is an exposure mechanism. The exposure mechanism 4 usually has a light source lamp, an optical path member, and a light exit window equipped with a light diffusing plate. It is provided in the area in front of the negative placement section in the longitudinal direction in order to obtain the necessary optical path length. The light from this exposure mechanism 4 is projected onto the negative film held by the negative holding member 3,
The transmitted light is projected through a projection lens onto photographic paper located directly below the negative placement area within the outer case 1, and printing is performed. Reference numeral 6 denotes a monitor window, which is used by the operator to visually check the light image projected onto the photographic paper to ensure proper printing.

[Problem that the invention seeks to solve]

However, the conventional photoprinting machine as described above has the following drawbacks. That is, as shown in FIG. 5, the negative film F is a long one, and usually each frame f
In the photographed image in , the direction perpendicular to the length direction of the negative film F is the vertical direction. Therefore, in a normal case, in a photoprinting machine, the negative film F is passed through the negative placement part of the table 2 by the arrow a on the table 2.
It is sufficient if it can be arranged so as to extend in the lateral direction indicated by , and can be held movably only in the lateral direction.

However, as shown in FIG. 6, the vertical direction of the photographed image of the half-size frame fN by a so-called half-size camera is usually the longitudinal direction of the negative film F. For this reason, when printing a half-size negative film F using a photoprinter, the vertical direction of successive images will be horizontal to the photoprinter operator, and the monitor image will be oriented horizontally. In this case, it is difficult to immediately grasp the state of the projected image, which is extremely inconvenient for performing sufficient checks efficiently.

(Means for Solving the Problems) The photographic printing machine of the present invention solves the above-mentioned problems, and includes a table and a negative film located in a negative placement section along the table. an exposure mechanism provided to protrude upward from the table and projecting exposure light onto photographic paper located below through the negative film held by the negative holding member; and a monitor window for viewing the light image projected on the photographic paper, and the negative holding member moves the negative film in both the horizontal and vertical directions along the surface of the table. It is characterized in that no obstacles are formed on the table in a region located laterally and vertically from the negative placement section.

[Effect]

According to the photoprinting machine with such a configuration, the negative film can be placed on the negative placement section of the table in either the normal horizontal direction or vertical direction according to the direction of the photographed image of the frame, and the operator can The user can always view the monitor image facing in the front direction, and therefore can check the projected image suitably and efficiently.

〔Example〕

1 and 2 show an embodiment of the present invention. In the present invention, the negative arranging section is provided with a film in a direction arbitrarily selected from either the horizontal direction or the vertical direction along the surface of the table 2. A negative holding member 3 is provided so that the negative film is held movably in the longitudinal direction while the negative film is stretched. Further, the exposure mechanism 4 has a column portion 4A that protrudes upward in an area adjacent to the area A located vertically forward of the negative arrangement portion on the table 2, and is supported in a so-called cantilevered state by this column portion 4A. The head portion 4B is located above the region formed at the upper end of the column portion 4A. The exposure mechanism 4 is configured in this head portion 4B, thereby inhibiting the movement of the negative film at least in the area A of the table 2 and in the area B located laterally to the left and right of the negative arrangement part of the table 2. table 2 without forming any protrusions or other obstructions.
Leave it on the table surface.

As shown in FIG. 3, for example, the exposure mechanism 4 includes a light exit window 41 having a downward light diffusing plate located directly above the negative placement section, and a light exit window 41 located directly above the negative placement section and a light emitting window 41 located at a level above the table 2 in the vertical direction of the table 2. an optical path member 42 extending horizontally, a light source lamp 43 provided to project light onto the optical path member 42, and a mirror 44 that reflects light from the optical path member 42.
According to such a structure, there is an advantage that the optical path length necessary for the exposure mechanism can be ensured and the whole can be made compact. 45 is a band cut filter, and 50 is a projection lens unit. The projection lens unit 50 includes a cylinder 51 integral with the negative holding member 3 and extending downward, and a projection lens 52 fixed to the lower end of the cylinder.

In FIG. 2, P is a photographic paper that is fed out from a magazine M, conveyed by a conveyance roller system 11, and after printing is completed, it is conveyed to a developing machine.

In the above, in order to hold the negative film so that it can extend in the horizontal and vertical directions and move in the extending direction in the negative placement section, for example, the negative film insertion hole 31 of the negative holding member 3 must be oriented in the horizontal direction. It is sufficient if the device can be arranged in either a vertically facing state or a vertically facing state. Specifically, table 2
By forming a rectangular hole 21 in the hole 21, making the cylindrical body 51 of the projection lens unit 50 into a rectangular cylindrical shape that fits the hole 21, and making the negative holding member 3 have a larger outline than the hole 21, projection Cylindrical body 51 of lens unit 50
is inserted into the hole 21, and the negative holding member 3 is engaged with the outer periphery of the hole 21 to hold it.As a result, the projection lens unit) 50 is pulled out, rotated 90 degrees, and then inserted into the hole 21 again. By inserting it inside, the direction of the negative film insertion hole 31 of the negative holding member 3 can be changed by 90 degrees, and as a result, the direction of the negative film can be oriented either horizontally or vertically. A negative film can be held by the negative holding member 3.

However, since the projection lens 52 of the projection lens unit 50 usually has a specific magnification depending on the size of the negative film frame, for example, a projection lens unit for half-size negative film always holds the negative film vertically. Therefore, the projection lens unit 50 can be attached only when the direction of the negative film insertion hole of the negative holding member 3 is in the vertical direction.

As described above, in addition to being able to insert the negative holding member 3 in both the horizontal and vertical directions, the negative holding member 3 is provided with negative film insertion holes in both the horizontal and vertical directions. You may use what you have.

In order to facilitate replacement of the projection lens unit, the tip of the head portion 4B of the exposure mechanism 4 may be configured to be movable upward, for example.

In FIG. 3, 60 indicates a negative film guide, and this negative film guide 60 is connected to the head portion 4 of the exposure mechanism 4.
It is attached to the front surface of the camera B, and guides the negative film F in the vertical direction and supplies it to the negative holding member 3, as shown by the chain line. By using such a negative film guide, when the negative film is fed in the vertical direction, the negative film is prevented from being located on the monitor window 6 and obstructing the operation of monitoring the projected image.

〔Effect of the invention〕

Since the photoprinting machine of the present invention has the above-described configuration, there are no obstacles on the table 2 not only in the horizontal direction but also in the vertical direction of the negative placement section, so that the negative film cannot be transferred to the operator. As a result, even when the negative film to be printed is half-size, the image of each frame can always be monitored in the front direction. Since the printing conditions can be appropriately set in the actual printing process, good photographic printing can be carried out efficiently.
