DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an information recording device using, for example, an optical fiber tube.

(Prior Art) Recently, various information recording devices using optical fiber tubes have been developed as information recording devices for sequentially recording, for example, one page of text on recording paper. This type of information recording device stores recorded information (textual information) that is input continuously line by line, reads out the recorded information in response to horizontal scanning of an electron beam of an optical fiber tube, and ,
In response to this, a character signal is generated, which is exposed to a photosensitive drum as a photosensitive member through an optical fiber tube, and the image formed on the photosensitive drum is transferred onto recording paper.

By the way, in conventional devices, the photosensitive drum is constantly charged. For this reason, there have been problems in that the photosensitive drum deteriorates quickly, shortens its life, and consumes a large amount of charging power.

(Problems to be Solved by the Invention) The present invention solves problems related to deterioration of image forming means and power consumption, and aims to suppress deterioration of image forming means and to
The present invention aims to provide an information recording device that can reduce power consumption.

[Structure of the Invention] (Means for Solving the Problems) This invention comprises a storage means for storing recorded information;
It is formed of an image forming means that forms an image according to recorded information stored in the storage means, and a control means that drives the image forming means in a state in which the storage means records predetermined recorded information.

(Operation) This invention prevents deterioration of the image forming means by driving the image forming means by the control means in a state in which recorded information is stored in the storage means, so that the image forming means is not constantly driven. This makes it possible to prevent this and reduce power consumption.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows an information recording device using an optical fiber tube according to the present invention, where 1 is an interface for sending and receiving information signals, 2 is a main control unit (central processing unit), and 3 is a clock pulse generator. 4 is a program counter, 5 is a storage device,
6 is a character signal generator, 7 is a shift register, 8 is a video amplifier, and 9 is a horizontal deflection circuit. The program counter 4 is connected to a clock pulse generator 3.
The main control section 2 programs a predetermined value.
Further, the storage section 5 stores input recorded information for each line, and has a storage capacity for one page of recorded information. On the other hand, 10 is an optical fiber tube (hereinafter simply abbreviated as OFT), 11
is the tube surface of OFT10, 12 is the horizontal deflection coil of OFT10, 13 is the photosensitive drum, 14 is the charger, 15
16 is a transfer charger, 17 is a static electricity remover,
18 is a cleaning brush, 19 is a cassette in which the recording paper P is stored, 20 is a paper feed roller, and 21 is a fixing device.

Next, the operation of the electrostatic recording apparatus configured as described above will be explained. FIGS. 2a and 2b show a case where, for example, the letter "A" is recorded and displayed on the recording paper P. In the figures, a line 23 indicates the sweep locus of the OFT 10, and a broken line 24 indicates the sweep locus. Further, it is assumed that the characters to be recorded and displayed are composed of, for example, a 5×7 dot matrix. However, now, when character information to be recorded is input continuously line by line, it is received by interface 1,
The signal is supplied to the main control section 2. The main control section 2 causes the input character information to be recorded in the storage device 5 sequentially for each line. Then, when the photosensitive drum 13 starts rotating, the charger 14 operates at the same time, and the photosensitive surface of the photosensitive drum 13 is charged. When this charged part passes through the tube surface 11 of OFT 10,
Start horizontal scanning of OFT10. That is, the main control unit 2 supplies a horizontal synchronizing signal to the horizontal deflection circuit 9 so as to match the rotational movement of the photosensitive drum 13 approaching the tube surface 11 of the OFT 10, so that the horizontal deflection circuit 9 adjusts the horizontal deflection. A deflection current is passed through the coil 12.

When horizontal scanning of the OFT 10 is started, the main control unit 2 first selects the first character of each character stored in the first line of the recording paper P from among the character information stored line by line in the storage device 5. , the dot signal of the first line of the character is selected from the character signal generator 6, and the dot signal of the first line is supplied to the shift register 7.
The shift register 7 converts the supplied dot signal into a serial signal and supplies it to the amplifier 8 in synchronization with the shift pulse output from the counter 4. The amplifier circuit 8 amplifies the supplied signal and applies it to the cathode of the OFT 10 as a video signal. This results in
The OFT 10 forms a latent image on the photosensitive drum 13 corresponding to the dot signal of the first line of the first character among the characters recorded on the first line. Next, the dot signal in the first row of the second character among the characters recorded in the first row is selected, and its latent image is formed in the same manner as described above. After repeating this operation until all the latent images corresponding to the dot signals of the first line of each character recorded on the first line are formed, OFT1
The zero electron beam is blanked and returned to the sweep starting point again. When the photosensitive drum 13 comes to an appropriate position, the OFT 10 starts sweeping again, and then selects the dot signal in the second line of the first character among the characters recorded in the first line. , forming its latent image. Subsequently, a dot signal in the second line of the second character among the characters recorded in the first line is selected, and a latent image thereof is formed. This operation is the first
This process is repeated until all the latent images for the second line and dot signals of each character recorded in the line are formed. In the same way, sweep is performed for all the dot signals on the 3rd line, 4th line, ... 7th line of each character recorded on the 1st line, and the sweep is performed on the dot signal on the 7th line. When this is completed, latent images for all characters in the first line have been formed. moreover,
A latent image is formed in the same manner as described above for each character recorded on the second line, third line, . . . of the recording paper p.
As a result, all of the character information for one page stored in the storage device 5 is recorded on the photosensitive drum 13 as a latent image. This is developed by the developing device 15, transferred to the recording paper P using the charger 16 in the transfer section, and fixed by the fixing device 21, thereby completing the recording display on the recording paper P. FIGS. 2a and 2b show an example of characters obtained on the recording paper P in this manner.

In the above-mentioned embodiments, a case has been described in which the present invention is implemented in an information recording device using OFT, but the present invention is not limited thereto, and can be similarly implemented in, for example, an information recording device using laser light.

According to the above embodiment, after predetermined recording information is stored in the storage device 5, the charger 14, the photosensitive drum 13
is driving. For this reason, the photosensitive drum 13 is always
It is possible to suppress deterioration of the photosensitive drum 13 compared to the case where the photosensitive drum 13 is charged, and the life of the photosensitive drum 13 can be extended.

In addition, since charging is not performed constantly, power consumption is low.

Furthermore, after storing the record information, the charger 14,
Since the photosensitive drum 13 is driven, if there is an error in inputting recording information, it is possible to input it again before starting electrostatic recording, and it is possible to prevent unnecessary recording due to erroneous information.

[Effects of the Invention] As described in detail above, according to the present invention, the image forming means is constantly driven by driving the image forming means by the control means in a state in which recorded information is stored in the storage means.
