In Japan October 26, 1934 1 Claim.

This invention relates to an apparatus for use in combination with a sound reproducing device wherein a plurality of pictures or other illustrations showing a story, poses of a dance, sceneries or advertisement pictures may, successively and .at regular intervals, be shown to the public, as the explanation, speech or musical accompaniment corresponding to the pictures is reproduced from the sound reproducing device.

For this purpose, the apparatus is provi-ded with a synchronizing mechanism, by means of which the rotary movement of the shaft of the turntable of a sound reproducing device such as gramophone and the like is transmitted to a shaft on which is mounted a number of cardboards drawn, painted or printed with necessary pictures to be shown to the audience, the cardboards being successively and at regular intervals freed from engagement with the supporter shaft .and disappear from sight by the rotary movement of the supported shaft i. e. as the shaft of the turntable rotates, thus synchronizing the picture show with the sounds reproduced from the record on the turntable.

The invention will now be more fully described with reference to the drawing, in which,

Figs. l and 2 show vertical and horizontal sections of one embodiment of this invention,

Figs. 3 and 4, front elevations of the two types of cardboards cut with holes, of different shape, and

Figs. 5 and 6, side and front elevations of the end of the supporting shaft for cardboards Referring to Figs l and 2, the numeral I represents the phonograph to which is attached the casing 2' of the apparatus according to this invention. On the upper part of the back wall of the casing 2, a supporter shaft 3 is journaled, the front part of the shaft 3 projecting into the casing 2. A locker pin 4 is pivotably mounted on the front end of the shaft 3, as shown more clearly in Figs. 5 and 6.

The cardboards on which the pictures to be shown are drawn may be divided into two groups.

,I The cardboards I6 of one group and those of the slit-s of theperforations IB and I9 are at right angles to each other.

The supporterv shaft 3 carries a ring 5, slidably mounted thereon, and a helical spring 6 wound on the said shaft 3 at the back of the ring 5, and adapted to press the said ring 5 against the back surface of the last one of the cardboards I6 and I1 supported by the shaft 3. Y

The device for synchronizing the picture show with the sound will be described hereunder. On the rear end of the shaft 3 projecting out of the casing 2 is formed a bevel gear 1, co-acting with another bevel gear 8, secured to the upper end of the vertical shaftv 9 supported by the brackets secured to the back wall of the casing 2. The shaft 9 carries at its lower end a worm wheel I0, co-acting with a worm II formed on a shaft I2 journaled on a bracket secured to the back wall of the casing 2. To the rear end of the shaft I2 one end of a flexible shaft I 4 is fastened, the other end I 5 of which is adapted to be connected with the shaft I3 of the turntable of the gramophone I, permitting the insertion of the upper end of the shaft I3 of the turntable, but prohibiting the rotational movement thereof relative to the flexible shaft.

For mounting the cardboards on the shaft 3, the pin 4 is turned about its axis to the horizontal position as shown in dotted lines in Fig. 5, and then cardboards I6 and I'I are alternatingly mounted on the shaft 3 by passing the pin 4 through the perforations I3 and I9 of the cardboards IB and I1 respectively. When the required number of cardboards have been mounted on the shaft 3, the pin 4 is turned back to the position shown in full lines in Figs. 5 and 6. The cardboards mounted on the shaft 3, will be pressed forward by means of the spring 6 acting on the ring 5, as hereinbefore stated, but will be retained in the position by the pin 4, and the pictures on the foremost cardboards I6 or I'I (as the case may be) may be viewed through the window 2| in the front wall 20 of the casing 2.

When the rotational movement of the shaft I3 of the gramophone commences, the movement will be imparted through the flexible shaft I4 to the shaft Y I2, then through the worm II and the worm wheel I0 to the shaft 9, and thence to the shaft 3 by means of the bevel gears 8 and 'I. The rotary movement of the shaft 3 will cause the pin to revolve in a vertical plane, while the cardboards remain stationary on the shaft. During the revolution of the pin 4, it will take such a position as to coincide with the slit of the perforation I8 (or I9) of the foremost cardboard I B (or I1), so that the cardboard will no more be retained by the pin 4. Then the cardboard will be pushed forward under the action of the spring 6, and will drop from off the shaft 3 by its own gravity, so that the next cardboard will appear before the window 2|, but Will be retained on the shaft 3 on account of the pin 4v not being in coincidence with the slit of the perforation on the cardboard. By the further rotation of the shaft 3 by a quarter of a circle, the pin 4 will be brought before the slit of the perforation I8 (or I9) of the second cardboard I6 (or l1), and will fall down from off the shaft 3, by the reason as hereinbefore stated. Thus, by the rotational movement of the shaft 3, cardboards I6 and l1 are alternatinglyfreed from engagement with the shaft 3 and disappear from sight at regular intervals (that is, four cardboards for each complete rotation of the shaft 3).

It will be easily understood that the interval at which each cardboard I 6 (or I1) disappears from sight may be adjusted by changing the rate of gearing down the speed of rotational movement of the shaft 3.

The apparatus may be used for amusement, advertising or educational purpose; the pictures on the cardboards may be of a story, poses of dancing, sceneries or advertisement pictures, which may be successively brought before the window 2| and retained in the position for a predetermined period when the corresponding sounds such as the explanatory speech on the story, scenery, or advertisement, or musical accompaniment is being reproduced from the record on the gramophone.

We declarev what we claim is:

In combination with a gramophone having a rotary turntable shaft; a card discharging device comprising a supporting shaft, a series of cards loosely mounted upon said supporting shaft, each of said cards having an opening extending in a direction ldifferent from that in which the opening of an adjacent card extends, a pin mounted upon one end of said supporting shaft and rotatable therewith, said pin fitting into the opening formed in any one of said cards in a predetermined position of said supporting shaft, means pressing said cards toward said pin, and means connecting said supporting shaft with the turntable shaft of the gramophone and transmitting'the rotation ofthe latter to said supporting shaft, whereby due to the rotation of said pin, said cards are caused to drop one by one from said supporting shaft.
