Description

[Detailed explanation of the invention] This invention relates to a rotating video viewer that rotates and feeds the video film wound around a rotating ring one frame at a time so that the video can be viewed through the lens opening. By operating the trigger, the rotary ring is rotated by a fixed angle, and the moving image of the film wrapped around the outer periphery of the ring can be magnified with a lens.The rotation is simple and easy to use. The purpose is to provide a video viewer.

Below, the structure of a rotating video viewer according to an embodiment of this invention will be explained with reference to the drawings. In the figure, 1 is a main body with a grip handle 2 that can be held with one hand, and the upper part of the main body is perpendicular to the grip handle 2. A horizontally protruding shaft cylinder portion 3 is provided, and one end surface of the shaft cylinder portion 3 is formed with ratchet teeth 3a. Reference numeral 4 denotes a rotary ring rotatably fitted to the main body shaft cylindrical portion 3, around which the moving picture film f is wound.
A central fitting opening 6 connected through the opening, a hook-shaped rubber hook 7 provided on the opening end plate 6a, and outer peripheral flanges 8a and 8b that prevent the film f from coming off.
This one flange 8b has ten tooth claws 9 protruding from the end surface thereof in the circumferential direction. 10 is a rubber-wrapped knob fitted on one end of the main body shaft cylindrical portion 3;
It has a protrusion 11 that engages and disengages from the ratchet tooth 3a, and a hook-shaped rubber hook part 12 that protrudes from the center,
It is configured as a ratchet type knob that rotates in only one direction by engaging and disengaging the protrusion 11 with the ratchet teeth 3a at the end of the cylinder. Reference numeral 13 denotes a rubber cord that is inserted into the main body shaft cylindrical portion 3 and stretched between the central rubber hooking portion 7 of the rotary ring 4 and the central rubber hooking portion 12 of the knob 10. By rotating the knob 10 in one direction while it is latched with the claw 23 of the golden rotating lever 21, the knob 10 is wrapped with rubber.
Reference numeral 14 denotes a peephole protruding from the front of the main body 1 facing the rotary ring 4, and a magnifying lens 15 is held in the opening by a lens holder 16. Note that this peephole 14 is located on the main body handle 2.
It is pivotally supported on the upper part by a pin 17 so as to be openable and closable, and is latched in the use state shown in FIG. 1 by a latching means (not shown) (for example, a structure in which a latching piece is engaged with a notch in the main body). . The purpose of providing the viewing port 14 with an opening/closing pin support structure is to facilitate the winding and replacement of the film f around the rotary ring 4. A screen plate 18 is attached to the end of the viewing port 14 on the pin support side. A compaction roller 19 is attached. The screen plate 18 has a window hole 18a that limits the viewing range of the peephole lens 15 to one frame (one moving image scene) of the film f, and the rotating ring 4
The lens is held close to the outer periphery of the lens and perpendicular to the optical axis of the lens. In addition, this screen board 1
8 may be provided integrally with the viewing port 14. The pressure roller 19 is pressed against the film-wound outer circumferential portion of the rotary ring 4 by the force of a leaf spring 20, and performs a rotation braking action to prevent rapid rotation of the rotary ring 4 due to rubber power. Reference numeral 21 denotes a trigger rotation lever provided in the upper part of the main body handle 2 so as to rotate around a pin 22, and has two pawls 23 that alternately engage and disengage from the toothed pawl portion 9 at the end of the rotating ring 4. 24, and a trigger operation part 25 that protrudes to a position where it can be operated with the fingers of the hand gripping the main body.
and a plate spring 27 that abuts against the main body stopper 26 and biases the entire lever to rotate in the direction in which the pawl 23 engages with the ring tooth pawl portion 9. .

Then, rotate the rubber-wrapped knob 10 in one direction to wind up the rubber cord 13, and in this state, the main grip handle 2
When the user holds the camera with one hand, places one eye on the viewing port 14, and operates the trigger rotation lever 21, the rotation ring 4 is rotated at a certain angle (example In this case, the film f wound around the outer periphery of the ring is intermittently fed one frame at a time, and the moving image of the film f can be magnified with the lens 15 and viewed. .

The rotating motion picture viewer of this invention is as described above, so that the user can see the motion picture of the film wound around the outer circumference of the rotating ring by simply holding the handle of the main body with one hand and pulling the trigger.
The structure is simple and an inexpensive product can be provided.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A main body with a handle that can be held with one hand, a rotating ring that is rotatably fitted to the cylindrical part of the main body and that wraps a video film around the outer periphery; A ratchet-type rubber-wrapped knob that rotates in only one direction is fitted into one end of the main body shaft cylindrical portion, and a tension ring is inserted between the rotary ring that is inserted into the main body shaft cylindrical portion and the central rubber hook of the rubber-wrapped knob. A rubber cord for rotating the film, a viewing hole protruding from the front facing the outer periphery of the rotating ring of the main body, and a magnifying lens fitted into the viewing hole allow the viewing range to be adjusted to one side of the film. It has a screen plate with a window hole that restricts only the pieces, and two pawls that are engaged and disengaged alternately by trigger operation on the toothed pawls at the end of the rotating ring. and a spring-loaded trigger rotation lever that intermittently advances the film wound around the ring one frame at a time by rotating the ring. (2) The above-mentioned viewing hole is supported by a pin in the upper part of the main handle so that it can be opened and closed, and a screen plate is attached to this opening/closing type viewing hole, making it easy to wind and replace the film around the rotating ring. A rotating moving image viewer according to claim 1 of the utility model registration claim, characterized in that the rotating video viewer is configured as follows.
