is rotatably supported. A support member 30 made of a ferromagnetic material is firmly fixed on the sleeve 28 at a position closest to the roller 3, and an arcuate magnetic needle-like Recording electrodes 31 are densely arranged along the axial direction of sleeve 28 . A predetermined number of the needle-like recording electrodes 31 are provided per unit length at a density corresponding to one pixel density (PEL). Thus, on the surface of the sleeve 28, spikes of conductive magnetic toner 6 are formed by the magnetic force of the multipolar magnet 29, and when the multipolar magnet 29 rotates in the direction of arrow C, the spikes are formed in the direction of arrow B. Move to. The blades 14, 15 are for regulating the height of the spikes generated on the sleeve 28 and the height of the spikes generated on the sleeve 32, which will be described later.

This height-regulated spike further moves in the direction of arrow B and is carried north of the nail-shaped recording electrode 31, and when it comes to the support member 30 via the electrode 31, the surface layer of the recording medium l Comes closest to 1a. At this time, by applying a positive voltage corresponding to the image signal to the needle-shaped recording electrode 31, the spiked toner 6 is positively charged and electrostatically attracted to the base 1b connected to the ground of the recording medium 1. The force causes it to adhere to the surface layer 1a of the recording medium 1. The above image signal is input to the input device 61
From there, it is collectively added to the electrode 31 via the control circuit 60. Since this recording medium 1 is moving in the direction of the arrow, images corresponding to the image signals sent sequentially are formed, and when the image for one screen is located on the display section 4, the recording medium 1 is moved in the direction indicated by the arrow. Stop.

On the other hand, the erasing means 13 includes a cylindrical erasing sleeve 32 made of a non-magnetic material, and the sleeve 32 is rotatable in the direction indicated by the arrow. A multipolar magnet 33 is disposed in the sleeve 32 in a fixed state yg. The erasing sleeve 32 is placed between the recording medium l and the writing medium 8, and the erasing sleeve 32
, the surface layer 1a of the recording medium 1 and the distance pattern 1 have grown, and are separated from the writing medium 8 by a distance. In addition, distance 11 + 1
2 varies depending on the magnetic force of the multipolar magnet 33, etc.
It is usually set to about 0.1 to 1ffi1. Further, below the erasing sleeve 32, distance! The blades 15 are arranged separated by L3. A roller 16 is in contact with the surface of the writing medium 8, and the roller 16 is used to prevent the writing medium 8 from being pushed during movement and to ensure a distance H12. A spike of toner 6 is formed on the erasing sleeve 32 by a multipolar magnet 33, and the spike of toner 6 moves in the same direction as the sleeve 32 rotates in the direction indicated by the arrow. The spikes of toner 6 are regulated in height by the blade 15 and remove the toner 6 adhering to the back surface of the writing medium 8, and further move in the direction of the arrow to adhere to the surface of the recording medium l. Therefore, toner adhesion on the recording medium l and toner stains on the back surface of the writing medium 8 are erased by the erasing sleeve 32.

FIG. 3 shows the drive mechanism of the board recording device according to this embodiment. In FIG. Ru. The gear 34 is meshed with a gear 37 fixed near one end of the multipolar magnet 29, and the gear 35 is meshed with a gear 38. This gear 38 and pulley 39 are connected to the roller 12 via an electromagnetic clutch 40.

The electromagnetic clutches 40 and 44 are controlled by a control u1 circuit (not shown) to connect and disengage the electromagnetic clutches 40 and 44.
When connected, the rotational force of the gear 38 is transmitted to the gear 43 via the 0-rail 12 and the bell 41. Electromagnetic clutch 4
4 are connected, the rotational force of the gear 43 is transmitted to the roller 3 and the erasing sleeve 32. Therefore, when the electromagnetic clutch 4o is disengaged and the electromagnetic clutch 44 is engaged, the rotational force is transmitted to the roller 3 and the recording sheet l moves, but the rotational force is not transmitted to the roller 12 and the writing medium 8 It remains stopped. On the other hand, when the electromagnetic clutch 40 is engaged and the electromagnetic clutch 44 is disengaged, the writing medium 8 moves conversely. When both the electromagnetic clutches 40 and 44 are in a disengaged state, both the recording medium 1 and the writing medium 8 are stopped.

Thus, by switching the electromagnetic clutches 40, 44 to the engaged or disengaged state, the recording medium 1 and the writing medium 8 can be driven independently of each other.

In addition, although the above-mentioned drive means was explained in the case of being driven by one motor, it is not limited to this.
The same operation as described above can be performed by using two or three motors and driving or stopping each motor.

In the above configuration, in the board/single recording apparatus according to this embodiment, images are displayed in the following manner. That is, to display image information on the recording medium l, =ti, the magnetic clutch 44 is connected, and at the same time the human power device 61 is connected.
Image information is extracted manually. Then, an image is formed on the recording medium 1 by the image forming means 5, and when the recording medium l on which the image is formed reaches the display section 4, the -11z magnetic clutch 44 is set to the uncoupled state jE, and the recording medium Stop l. This display image is visible from the front of the device through the transparent writing medium 8 at a distance of 1 m. When writing additional characters on the above display image, write on the writing medium 8 with a felt-tip pen or the like. If you want to change the image that has been added, connect only the electromagnetic clutch 40, move only the writing medium 8, and display the new part of the writing medium 8 on the display section 4.
to be placed in By doing so, new content can be written on the writing medium 8. Also, writing medium 8
If you want to change only the image on the recording medium l while leaving the image written on the top as it is, use only the electromagnetic clutch 44 as the connecting member 7B again, move only the recording medium l, and input a new image from the input device 61. Manually generate image information. By doing so, only the image on the recording medium l can be changed while leaving the image on the writing medium 8L unchanged.

Situations such as this where one part of the image information is left unchanged while the other is changed include when displaying a problem during a school class and writing down various answers, or when displaying an original draft during a meeting. Various cases can be considered, such as adding various proposals to this.

In addition, in the embodiment shown in FIG. 1, a case has been described in which the recording medium l and the writing medium 8 are formed into an endless belt shape and are circulated. However, the present invention is not limited to this, and the recording medium l and the writing medium 8 are
It goes without saying that the writing medium 8 may simply be formed into a belt shape, and both ends thereof may be wound around rollers on the supply side and take-up side, respectively, and the medium may be moved back and forth between the two rollers.

(Effects of the Invention) The present invention has the above-described configuration and operation, and can easily change an image on a recording medium or a writing medium.
