び消去動作を説明する。Next, the recording medium used in the present invention will be described. The recording medium is a sheet material in which a base material is coated with a recording material which changes between a transparent state and a cloudy state depending on a heating temperature, and the transparent state and the cloudy state can be alternately and repeatedly used. This recording material is disclosed in JP-A-55-
Since it has been proposed in Japanese Patent No. 154198, its detailed configuration is omitted here. The change characteristics of the cloudiness and transparency of this recording material are shown in FIG. 4, and the characteristics will be described. For example, when heating the recording medium opaque state current at room temperature (T 1) to a temperature region of T 2 through T 3, the recording medium becomes transparent state, that state be returned to room temperature (T 1) is held . Further, when a transparent recording medium is heated to T 4 at room temperature, the recording medium becomes cloudy and passes through the clearing temperatures T 2 to T 3 when returning to room temperature (T 1 ). It does not become transparent, and the cloudy state is maintained even when returned to room temperature (T 1 ). As described above, this recording medium is characterized in that the change between white turbidity and transparency is caused by heat and changes repeatedly. Next, the recording and erasing operations of the recording apparatus of the present invention will be described.

を繰り返し何回でも使用することが可能となる。First, the recording medium is inserted into this apparatus. The inserted recording medium is conveyed and guided by the conveying roller 4 and the conveying guide 5, and the recording medium is conveyed from the position detection sensor 6 to the erasing heat generating head 1. The erasing heat-generating head 1 presses and conveys the recording medium together with the platen roller 3, and at the same time as the erasing timing based on the output signal of the position detection sensor 6, applies heat energy capable of making the recording medium transparent so as to cover the recording medium. Make it transparent. Here, heat energy that can be made transparent is applied to the recording medium regardless of whether a visible image is recorded before the recording medium is inserted.
The recording medium made transparent by the erasing heating head 1 is conveyed to the thermal head 2 via the conveying guide 5. Ser
In the round head 2 as well as the erasing heat-generating head 1, while the recording medium is pressed and conveyed by the platen roller 3, the recording is performed in accordance with the recording timing based on the output signal of the position detection sensor-6. By selectively applying a pulse voltage corresponding to an image signal to heat energy that may cause clouding, the recording medium is partially clouded and a visible image is recorded.
Therefore, a visible white image is formed on the discharged recording medium on the transparent sheet. When the recording medium is used again, the recording medium inserted in the recording apparatus is conveyed by the conveyance roller 4 and the conveyance guide 5 as before, and the cloudy visible image previously written by the erasing heat generating head 1 is reproduced. The image is erased and a new visible image is formed by the thermal head 2. By repeating the above, it becomes possible to use the recording medium repeatedly as many times as desired.

温度に制御する。The erasing heating element head used in the recording apparatus according to the present invention conducts pulse current to heat the heating resistor to heat the recording medium and modulate the pulse width for recording. The temperature is controlled so that the visible image on the medium can be erased.

さ分の通電パルスが出たところで通電を終了させる。First, in accordance with the recording timing based on the output signal of the position detection sensor-6, immediately before the recording medium reaches the erasing heating element head 1, the erasing heating element head 1 is moved.
Is rapidly heated to the clearing temperature (T 2 to T 3 ). This process, the recording medium heating element head 1 for erasing upon reaching the erasing heat generator head 1 is clearing temperature (T 2 ~T 3)
Therefore, after that, a continuous constant energizing pulse is applied to the erasing heating element head 1 to make the recording medium transparent. FIG. 5 shows how the energizing pulse and the temperature of the erasing heating element head 1 change. In this embodiment, the energization cycle is 10 ms
(C), the energization time (P) is fixed at 9 m at the start of recording.
When the transparent temperature is reached, heating is performed at a constant energization time (P) for 2 ms, and energization is terminated when an energization pulse corresponding to the length of the recording medium appears.

る。Next, the control section of the energizing pulse applied to the erasing heat generating head 1 will be described. FIG. 6 shows a block diagram of the configuration of the control circuit used in this embodiment. The number of pulses in a series of energizing pulse trains is N n , the energizing cycle is C n , and the energizing time is P n . N n, C n, P n is previously de - are written into the ROM20 as data, control - de by providing an address signal 24 to the ROM20 by La 22 - data N i,
C j and P k are read out and sequentially sent to the register 26 and the data latch 28. The controller 26 sends the data latch control 30 to the register 26 and the data latch 28, and the data is sent to the N pulse counter 32 and the energization time generation counter section 34. In the energization time generation counter 34, the energization time for one pulse is determined by the data C j and P k , the data is input to the driver unit, and the erasing heat generating head is driven. At the same time N
The pulse counter 32 counts the number of times and outputs the data.
A signal is sent to the controller 22 when only the data N i has been counted, and the controller 22 receives the signal and receives the next address signal 24, the register 26 and the data latch 28.

可能となる。Further, the erasing heating element head 1 is characterized in that it has a smaller heat capacity than the heating roller. Therefore, since the rising characteristic is good, it is sufficient to start heating only when the recording medium is conveyed, and the power consumption of the entire recording apparatus can be suppressed low. However, the erasing heating element head 1 has a small heat capacity in order to improve the rising characteristics, and the amount of heat given to the recording medium becomes smaller at the rear end than at the front end of the sheet by only a constant pulse energization. is there. Therefore, it becomes impossible to erase the entire surface of the recording medium. Therefore, in the present invention, the energizing time of the energizing pulse applied to the head for erasing the entire surface is changed. That is, the amount of heat generated by the heating resistor is increased by increasing the energization time toward the trailing edge of the recording medium, and control is performed so that erasable thermal energy is provided even at the trailing edge of the recording medium. In this embodiment, the energization cycle is 10 ms
(C), and the energization time (P) is fixed at 2 m at the start of recording.
erasing is performed, and the temperature of the recording medium reaches the transparent temperature lower limit (T
When approaching 2 ), the energization time (P) is lengthened by 0.1 ms per cycle. By performing control in this way, it is possible to apply heat to the entire surface of the recording medium so that it falls within the transparentization temperature range (T 2 to T 3 ).

However, the cloudy state is regarded as the erased state, and the erasing heating element head is controlled so that the recording medium is in the cloudy temperature range, and the thermal head is used. It is also possible to form a recorded image by controlling the recording medium so that the recording medium falls within the transparentization temperature range. Further, the recording material to which the present invention can be applied is not limited to the materials of the examples, and can be applied to a recording material using a leuco dye as a color-forming source that reversibly changes color tone only by controlling thermal energy. Further, as the heating resistor of the erasing heating element head, the thick film resistor is used, but the thin film resistor can also be used for erasing in the same manner.
