It is installed on described projector.
Have employed technique scheme, the beneficial effects of the utility model are:
(1) being provided with egative film holding tray due to projector both sides and dish collected by egative film, courseware development can be become the end by teacher
Sheet film, master film is wound in egative film holding tray and egative film is collected between dish, and when giving lessons, teacher shakes crank, ratchet spine
Under pawl effect, drive egative film to collect dish and egative film holding tray one-directional rotation, need the place that emphasis is told about, then stop operating egative film
Collect dish, it is achieved thereby that arbitrarily play courseware continuously, improve teaching efficiency.
(2), owing to being provided with reduction torsion spring between egative film holding tray and projector, when giving lessons, reduction torsion spring stress produces shape
Become, when, after end of giving lessons, teacher has only to open ratchet, and master film just can be under the effect of reduction torsion spring, automatically the end of by
Sheet collects dish reverse-winding on egative film holding tray, from without the most additionally rewinding, decreases the extra work of teacher
Amount.
(3) owing to being provided with transition roller on projector, master film is collected at egative film holding tray and egative film and is wound around between dish
Shi Gengjia is smooth and easy, it is to avoid master film jam, discounting phenomenon, not only makes to give lessons smooth, also extends egative film
The service life of film.

Detailed description of the invention
Below in conjunction with the accompanying drawings, by specific embodiment this utility model is described in detail, but these particularizations
The purposes of embodiment and purpose are only used for enumerating this utility model, not constitute real protection scope of the present utility model and appoint
Any restriction of what form, more non-is confined to this by protection domain of the present utility model.
As Fig. 1 and Fig. 2 jointly shown in, ideology and politics teaching multimedia device described in the utility model, including projection
Instrument 1, projector 1 has egative film imaging table 101 and is positioned at the projection lens 102 above egative film imaging table 101, the one of projector 1
Side is rotatablely equipped with egative film holding tray 2, and the opposite side of projector 1 is rotatablely equipped with the egative film corresponding with egative film holding tray 2 and receives
Taking dish 3, egative film holding tray 2 and egative film are collected dish 3 and are all used disk-like structure, and centre is designed with accommodating the ring of master film 12
Connected in star 201, courseware development can be become master film 12, master film 12 to be wound in egative film holding tray 2 and egative film receipts by teacher
Take between dish 3, and just past egative film imaging table 101, project under the effect of projection lens 102 on screen, for reality
The seriality now given lessons, egative film holding tray 2 uses one-directional rotation, and its structure is, egative film is collected and is installed with ratchet 4 on dish 3,
