Description

[Detailed Description of the Invention] "Field of Industrial Application" The present invention relates to an image transmitting/receiving device using a telephone that instantly transmits and receives images such as pictures and characters using the transmitter of the telephone as a medium.

"Prior Art" Conventionally, there has been a display device that displays an image on a fluorescent surface based on image data, a writing member that inputs image data to the display device by a writing operation on the fluorescent surface, and image data of the display device. There is a technology that includes a sound signal input/output member that inputs and outputs sound signals to and from the handset of a telephone, and displays an image displayed on a display device on the transmitting side on a display device on the receiving side via a telephone line. .

"Problems to be solved by the invention" The above-mentioned conventional technology is mainly applied to stationary objects such as computer terminal equipment, and for example,
As shown in Publication No. 67895 and Japanese Patent Application Laid-open No. 48-34604, even if a writing member such as a light pen or a keyboard and a sound signal input/output member such as a coupler are connected to the display device separately by wiring cords, There is no problem since the operator performs image transmission and reception operations while sitting on a chair, etc.; however, for example, if the operator carries a display device, writing member, and sound signal input/output member and uses a public telephone to transmit and receive images. It was very difficult to handle and had problems that made it impossible to use it as a portable device.

"Means for Solving the Problems" However, in the present invention, a sound signal input/output member is integrally provided at the upper end of the writing member, and these are connected to a display device by a wiring cord.

"Function" Therefore, the writing member and the sound signal input/output member can be handled as one unit, reducing the number of portable points and improving portability. All input and output of image data from the display device to the device can be performed with one hand, and the operability is also improved so that it can be easily handled even under adverse environments at a portable location.

"Embodiments" Examples of the present invention will be described below in detail based on the drawings. The drawing is a system diagram of the image transmission/reception system according to the present invention, and in the drawing, 1 is a telephone equipped with a receiver 2 and a transmitter 3 (however, the telephone main body is not shown);
Reference numeral 6 denotes a display device structured to visually display images such as pictures and characters, a light pen 4 which is a writing member structured to input the image by a writing operation, and a light pen 4 that converts the image data into a sound signal to the receiver 2 or the transmitter. The light pen 4 is provided with a microphone speaker 5 which is a sound signal input/output member structured to input and output the light pen 4, and is connected to the display device 6 via a wiring cord. ing.

The display device 6 is provided with a liquid crystal type fluorescent surface 6a for displaying dots, and the fluorescent surface 6a
The power switch 10 turns on the light, and the contents of the random access memory (hereinafter referred to as RAM) held in each pixel 6b constituting the luminescent surface 6a are inverted to create a black-on-white image display mode and a black-on-white image display mode. An image display changeover switch 11 for switching to a white image display mode, and a clear switch 12 for resetting the RAM and erasing the image are provided.

Note that the image data of the display device 6 is sequentially taken out by a shift register, and is equipped with a DC power supply.

Further, the light pen 4 has a built-in reflected light sensor, and is provided with a write switch 7 which activates this sensor and puts the display device 6 into an image input state.

Furthermore, the microphone speaker 5 is provided with a transmission switch 8 that operates the microphone and switches the display device 6 to a transmission state (that is, a state that converts image data into a sound signal and outputs it); A receiving switch 9 is provided for switching the receiver to a receiving state (that is, a state in which audio signals are converted to image data and inputted), and a ring-shaped rubber body that fits into the receiver 2 or the transmitter 3 is integrally formed on the transmitting and receiving side. It is installed on.

This embodiment is configured as described above, and images are sent and received using a telephone line that is currently in use.

First, the sender turns on the power switch 10 to light up the fluorescent surface 6a, and while keeping the writing switch 7 on, brings the tip of the light pen 4 into contact with the fluorescent surface 6a to write down the transmitted image as appropriate. . Due to this writing action, the reflected light sensor of the light pen 4 detects the reflected light of the pixels 6b... of the handwritten part, and the sensor output is input to the display device 6 via the wiring cord, and the address of the pixel 6b... be
At the same time, the transmitted image is stored in the RAM, the pixels 6b are turned off, and the transmitted image is visually displayed on the fluorescent surface 6a.

After the sender reports the start of image transmission to the receiver, the sender fits the microphone speaker 5 to the transmitter 3 via the rubber and turns the transmitter switch 8.
is held on to put the display device 6 in the transmitting state, while the receiver turns on the power switch 10, fits the microphone speaker 5 to the handset 2 via the rubber body, and holds the reception switch 9 on. to put the display device 6 into the receiving state. As a result, in the display device 6 on the transmitting side, the image data stored in the RAM is sequentially retrieved by the shift register, and the image data is applied to the power amplifier and also controls the speaker operation via the wiring cord. The image data is output to the microphone speaker 5, and the image data is converted into a sound signal and output to the transmitter 3.
On the other hand, the display device 6 on the receiving side converts the sound signal input from the receiver 2 into image data via the microphone-operated microphone speaker 5.
The image data is stored in the RAM via the wiring code, and the pixel 6b based on the image data is
is turned off. As a result, the same image that is visibly displayed on the phosphorescent surface 6a of the transmitting side display device 6 is also visibly displayed on the phosphorescent surface 6a of the receiving side display device 6.

"Effects of the Invention" As is clear from the above embodiments, the present invention includes a display device 6 that displays an image on a fluorescent surface 6a based on image data, and a display device that displays image data by a writing operation on the fluorescent surface 6a. 6, and a sound signal input/output member 5 that inputs and outputs the image data of the display device 6 as a sound signal to and from the handsets 3 and 2 of the telephone. In an image transmitting/receiving device using a telephone that displays an image to be displayed on a display device 6 on the receiving side via a telephone line, a sound signal input/output member 5 is integrally provided at the upper end of the writing member 4 and these are displayed with a wiring code. Device 6
The writing member 4 and the sound signal input/output member 5 can be handled as an integrated unit, and the number of portable points can be reduced to improve portability, and the image input to the display device 6 can be In addition, inputting and outputting image data from the display device 6 to the receiver 2 or the transmitter 3 of the telephone set can all be performed with one hand, and the operability is improved at the same time, making it easy to handle in adverse environments at a mobile phone site. It has a remarkable effect.
