Abstract
The invention discloses a transparency automatically-positioning device, comprising a power supply (1), a CPU (2), a driver (3), a motor (4) and a transparency (5), wherein the output of CPU(2) drives the motor (4) to rotate through the driver (3). The motor (4) drives the transparency (5) to do horizontal movement. The invention is characterized in that: the transparency (5) is composed of a film base (5a) and a plurality of images (5b) on the film base, wherein the film base is provided with an upper sensing point and a lower sensing point corresponding to positions of the images; an upper sensor (6) and a lower sensor (7) are respectively arranged on the upper sensing point and the lower sensing point respectively, and are respectively connected with the CPU (2). The invention overcomes the technical drawbacks of the prior transparency positioning device that positioning holes wear easily and transparencies can not automatically position. The invention has the advantages of simple structure and durability, and particularly is suitable to be used together with long-focus lens high-power optical projectors.
Description
Technical field
The present invention relates to projector, particularly a kind of automatic positioning equipment for projection film.
Background technology
The locating device of existing projection film generally all is to pass pilot hole on the film by pilot pin, and projection film is carried out mechanical positioning.There is following technological deficiency in such film positioning device: the pilot hole on the film weares and teares easily, causes the location inaccurate, and has shortened the serviceable life of film.
Summary of the invention
The technical problem to be solved in the present invention is: the problem that the existing projection film locating device pilot hole on the film that weares and teares easily, film can not automatic accurate location.
A kind of automatic positioning equipment for projection film, comprise power supply 1, CPU2, driver 3, motor 4, film 5, the output of CPU2 is rotated by driver 3 drive motor 4, drive film 5 by motor 4 and do tangential movement, it is characterized in that: film 5 is made of several images 5b on sheet base 5a and the sheet base, the sheet base is provided with corresponding to the last induction point 5c of picture position and following induction point 5d, and last induction point 5c and following induction point 5d place are provided with one respectively and go up inductor 6 and a following inductor 7, and last inductor 6 is connected with CPU2 respectively with following inductor 7.
Induction point is the printing opacity aperture, and the inductor corresponding with the printing opacity aperture is the optocoupler sensor.
Induction point is a cursor will, and the inductor corresponding with cursor will is photoelectric sensor.
Induction point is the magnetic sign, and the inductor corresponding with the magnetic sign is magnetic inductor.
Power supply is powered to CPU, and CPU at first sends instruction to driver, and driver control driven by motor film is moved horizontally, and CPU also is connected with two inductors, and one is last inductor, and one is following inductor.When the last inductor of last induction point process on the film, last inductor sends information to CPU, the CPU opening entry; When the following induction point on the film passes through to descend inductor, following inductor sends information to CPU, the information that CPU receives by analysis, send instruction to driver, the control motor is adjusted the position of film, film can accurately be located, and when film deformed owing to reasons such as stretchings, CPU also can proofread and correct its position.
The present invention has overcome existing projection film locating device, and the film pilot hole is easy to wear, the technological deficiency that projection film can not automatic accurate location.The present invention also has advantages such as simple in structure, durable in use, is particularly suitable for and the supporting use of long-focus high-power optical projector.
