Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a slide holding device such as a color slide in which a positive film is supported by a mount.

[Prior Art and its Problems] It has been a common practice to make a color negative by making a close-up of a color slide on a color film, print and expose the color negative on a color paper, and then develop it to make a color print. ing.

When forming a positive image of a color slide on a color film in forming the color print, it is necessary to stably hold the color slide.

The prior art of a color slide holding device is shown in FIGS. 4 and 5. In this holding device, a fixed holding piece 21 is provided on one side of the upper surface of the slide support base 20,
A guide groove 23 is formed on a surface of the guide member 22 facing the holding piece 21 so as to face the holding piece 21, and a movable holding piece 24 slidably incorporated in the guide groove 23.
Is moved toward the fixed holding piece 21 by the spring 25 incorporated in the back part thereof, and both sides of the color slide A are held by the fixed holding piece 21 and the movable holding piece 24.

By the way, in the above holding device, since the movable holding piece 24 is slid along the guide groove 23 of the guide member 22, it is necessary to make the width dimension of the guide groove 23 larger than the thickness dimension of the movable holding piece 24. is there.

For this reason, a gap is created between the guide groove 23 and the movable holding piece 24, and the movable holding piece 24 rattles due to the gap, and there is an inconvenience that the color slide A cannot be stably held.

[Purpose of device]

Therefore, an object of the present invention is to provide a slide holding device which can solve the above-mentioned inconvenience and can hold a slide such as a color slide extremely stably.

[Constitution of device]

In order to achieve the above object, the present invention provides a movable holding piece provided with a guide member whose outer surface is a guide surface on the upper surface of a slide support, and slidably supported along the guide surface of the guide member. And a slide holding groove is formed in the facing surface of the fixed holding piece whose lower portion is supported by the upper surface of the slide support base, which is arranged so as to face the movable holding piece, and the movable holding piece is provided between the guide member and the movable holding piece. In this structure, a spring is provided so as to provide elasticity in a direction in which the piece is pressed against the guide surface and a direction in which the piece is moved toward the fixed holding piece.

[Action]

According to the above structure, since the movable holding piece is pressed against the guide surface of the guide member by the elastic force of the spring in the state of holding the color slide by the fixed holding piece and the movable holding piece, the color slide is extremely stable. Can hold well.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

As shown, a recess 2 is formed on one side of the upper surface of the slide support 1.
Is provided, and the front surface of the guide member 3 provided on the bottom surface of the recess 2 is a guide surface 4 finished with high accuracy.

The holding piece 5 arranged on the front surface of the guide member 3 has the above-mentioned guide surface 4
Is supported slidably along the lower part of the movable holding piece 5 is fitted in the recess 2.

A fixed holding piece 6 is provided on the other side of the upper surface of the slide support base 1 so as to face the movable holding piece 5. The movable holding piece 5 and the fixed holding piece 6 face each other with the color slide A. A slide holding groove 7 is formed on which both sides can be fitted.

Pins 8 project from the upper and lower surfaces of the movable holding piece 5, and a spring 10 is bridged between the pin 8 and a pin 9 projecting from the upper and lower surfaces of the guide member 3 by the spring 10. The movable holding piece 5 is pressed against the guide surface 4 of the guide member 3 and is drawn toward the fixed holding piece 6.

In order to limit the amount of movement of the movable holding piece 5 with respect to the fixed holding piece 6, a protrusion 11 that is engageable with the side surface of the guide member 3 is provided on the back surface of the movable holding piece 5.

The mechanism for limiting the movement amount of the movable holding piece 5 is not limited to the above-described configuration. For example, one of the guide member 3 and the movable holding piece 5 has a long hole formed in the left-right direction, and the other has a long hole. You may make it attach the pin inserted in a long hole.

The slide holding device shown in the embodiment has the above structure, and when holding the color slide A, the movable holding piece 5 is used.
Slides the movable holding piece 5 in a direction away from the fixed holding piece 6 to form a space in which the color slide A can be fitted with the fixed holding piece 6, and then the color slides between the both holding pieces 5 and 6. Fit A and place it on the slide support 1.
The movable holding piece 5 is moved by the elastic force of the spring 10, and the collar slide A is held from both sides by the fixed holding piece 6.

In the holding state of the color slide as described above, since the movable holding piece 5 is pressed against the guide surface 4 of the guide member 3 by the elastic force of the spring 10, the movable holding piece 5 moves in the direction perpendicular to the slide holding direction. As a result, the color slide A can be held extremely stably.

〔effect〕

As described above, according to the present invention, the movable holding piece that holds the color slide with the fixed holding piece has a direction in which the movable holding piece presses the guide surface of the guide member provided on the upper surface of the slide support base, and the fixed holding piece. Since the elastic force of the spring is applied in the direction in which the color slide moves toward one side, the color slide can be held extremely stably and the positioning accuracy of the color slide can be improved.
