The present invention relates to a reader that can be read by rotating the roll film printed pictures and letters.

In reading a book printed on ordinary paper, you read by handing each side of the bookcase. This type of reading was inconvenient to do the necessary reading, even if it is impossible and even possible to turn over the bookshelf if you have a car, a train, lying posture or standing on the other hand in one hand.

The present invention prints the letters or pictures necessary for roll film instead of turning a book over a conventional sheet, and then rotates the book reader without reading the bookshelf by hand. The purpose is to provide.

Specific embodiments of the reader of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, the roll film 14 on which characters and the like are printed is wound or unwound on two pivoting shafts 11 and 11 'so that the characters and the like can be visually recognized through the transparent window 15. On the contrary, the driving unit 20 is driven by the switching action of the speed adjusting unit 1 capable of adjusting the speed of the acceleration and decrease, and the movement speed or direction is adjusted according to the signal of the speed adjusting unit 1 by the power of the driving unit 20. It consists of the driven part 30 and other apparatus which supports them.

In the present invention, the display unit 10 for displaying characters and the like has two rotating shafts 11 and 11 'supported by the rotating rollers 13, 13', 13 " and 13 '" The roll film 14 is printed with various characters and pictures on the surface portion 14 'and spreads out the back surface of the transparent window 15 as shown in FIG. It is to be wound in ').

In addition to the rotating shafts 11 and 11 ', the guide rollers 16 and 16' help to smoothly transport the roll film in order to assist the stable rotation of the roll film.

The display unit 10 is provided with a plurality of teeth 17 on the inner circumferential surface of the rotary roller, the second rotation shaft 32, 32 to rotate in response to the driving force transmitted from the operation of the various transmission gears and the belt of the driven portion 30 ') To fit. The light emitting device 18 is installed at the center of the display unit 10 so that the light switch 2 'of the speed adjusting unit 1 can be turned on at night.

In the present invention, the driving unit 20 is driven when it is energized by a conventional driving motor and controls the driving speed by a variable resistor.

The driving force generated by the driving unit 20 is transmitted to the driven unit 30 shown in FIG. 3 to be accelerated forward rotation, accelerated reverse rotation, constant speed rotation, etc. by a belt, a chain or an electric motor.

When the driving force is generated and the driving force is generated in the driving unit 20, the first gears 31, 31 ', ..., etc. are rotated, and the rotation is accelerated forward rotation, acceleration reverse rotation, constant speed forward rotation by a belt, etc. (32,32 ') rotation.

The speed control part (main body) 1 of the present invention is a resilient pressure switch or other electronic sensor switch on one surface of the present device as shown in FIG. 1 and presses or contacts the constant speed forward rotation switch 2 to energize it. In this case, the rotational force transmitted through the driven part 30 rotates the second rotational shaft 31 at constant speed so that the rotational shaft 11 fitted thereto is also rotated so that the roll film 14 is transported at a constant speed so that the transparent window ( As you pass 15), you will display the necessary characters and pictures.

In addition, when the acceleration forward rotation switch 3 is operated, the roll film 14 is rapidly wound because the second rotation shaft 31 is rotated in an accelerated state.

If you operate the acceleration reverse rotation switch (4) is the reverse operation. The stop button 5 temporarily stops when it is turned on.

When the count button 6 is turned on when the count of the reading completion time is required, the reading time is displayed on the clock display unit 7. The clock display unit 7 can be provided with a time setting switch 7 ', a general clock changeover switch 7' ', a stopwatch switch 7' ", etc. The above speed conversion is adopted in a conventional cassette recorder or the like. Detailed description thereof will be omitted.

The present invention can be installed separately to the rotation speed deceleration converter (8) to adjust the amount of voltage supplied from the power source to convert the speed of the motor being driven.

In addition, the present invention may incorporate the circuits so that AM and FM broadcasts can be listened to, and then rotate the dials 9 and 9 'to select a broadcast and then listen to the broadcast using the socket 9' 'using a receiver or the like. .

The specific operation example of this invention is demonstrated.

First, the user purchases a book made of roll film 14 on the market, and the teeth 17, 17 'at both ends of the rotation shafts 11, 11' of the display unit 10 are rotated on the second rotation shafts 32, 32 on the main body. The rotary rollers 13,... 13 '"are fitted to the main surface projection of').

Subsequently, when the roll film is rewound with the acceleration reverse rotation switch 4 and the constant speed forward rotation switch 2 is turned on, the contact wheel 16 'is pushed down to compress the roll film 14 to the power rod 16' '. The fastener 33 is also inserted into the corresponding insertion groove 33 ′ of the display unit so that the second rotation shafts 32 and 32 ′ are slowly rotated by the driving force of the motor driving unit 20. ') Is also rotated so that the roll film 14 is guided through the lower surface of the transparent window 15 by the guide rollers 16 and 16', so that the user can see the writing on the surface of the roll film 14 and the like. Can be visually recognized. At this time, the rotation speed deceleration converter 8 can be read by adjusting or adjusting according to the reading ability of the user. Can also be judged.

Reading at any time by turning on the optical switch 2 'at night.

When the reading becomes tired for a long time, the pause button 5 is turned on and the AM and FM broadcasts can be listened to using the dials 9 and 9 '.

Claims (3)
