び消去動作を説明する。Next, the storage medium used in the present invention will be described. The storage medium is a sheet material in which a base material is coated with a recording material which changes to 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-

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, if a storage medium that is currently in a cloudy state at normal temperature (T 1 ) is heated to a temperature range of T 2 to T 3 , the storage medium will be in a transparent state, and that state will be maintained even if returned to normal temperature (T 1 ). . 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 storage 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, a storage medium is inserted into this device. The inserted storage medium is transported and guided by the transport roller 4 and the transport guide 5, and the storage medium is transported from the position detection sensor 6 to the erasing heating head 1. The erasing heat generating head 1 presses and conveys the storage medium together with the platen roller 3, and at the same time, applies heat energy capable of making the storage medium transparent in synchronization with the erasing timing based on the output signal of the position detection sensor-6. Make it transparent. Here, heat energy that can be made transparent is applied to the storage medium regardless of whether a visible image is recorded before the storage medium is inserted.
The storage medium made transparent by the erasing heat generating 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, recording is performed in accordance with the recording timing based on the output signal of the position detection sensor-6. A storage medium is partially clouded by selectively applying a pulse voltage corresponding to an image signal to heat energy that can cause clouding, 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 storage 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 heating head 1 is displayed. The image is erased and a new visible image is formed by the thermal head 2. By repeating the above, the storage medium can be repeatedly used any number of times.

温度に制御する。The erasing heating element head used in the recording apparatus according to the present invention performs pulsed energization to heat the heating resistor to heat the storage medium and modulate the pulse width for storage. 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 storage medium reaches the erasing heat generating head 1, the erasing heat generating 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 constant current pulse is applied to the erasing heating element head 1 to make the storage 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 temperature reaches the transparentization temperature, 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 storage 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.

ような熱を与えることが可能となる。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 characteristics are good, it is sufficient to start heating only when the storage medium is conveyed, and the power consumption of the entire recording apparatus can be kept low. However, the heat generating head 1 for erasing has a small heat capacity in order to improve the rising characteristics, and as shown in FIG. 7A, the amount of heat given to the storage medium by the constant pulse energization is greater than that at the tip of the sheet. The rear end may become smaller. Therefore, it becomes impossible to erase the entire surface of the storage medium. Therefore, in the present invention, as shown in FIG. 7B, the energizing time of the energizing pulse applied to the head for erasing the entire surface is changed according to the position of the storage medium. In other words, the amount of heat generated by the heating resistor is increased by increasing the energization time toward the rear end of the storage medium, and control is performed so that erasable heat energy is provided even at the rear end of the storage medium. In this embodiment, the energization period is set to 10 ms (C), the energization time (P) is erased at a constant 2 ms at the start of recording, and the energization time (T 2 ) is reached when the temperature of the storage medium approaches the transparent temperature lower limit (T 2 ). In P), the energization time 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 ).

It has become possible to apply heat such as entering T 3 ). Here, N 1 is the number of pulses until the storage medium approaches the lower limit (T 2 ) of the clearing temperature.

However, the cloudy state is set to the erased state, and the erasing heating element head is controlled so that the storage medium is in the cloudy temperature range, and the thermal head is used. If the storage medium is controlled so that the storage medium falls within the transparentization temperature range, the transparent state can be used as a recorded image. Further, the recording material to which the present invention can be applied is not limited to the materials of the examples, and can also be applied to a memory material using a leuco dye that reversibly changes color tone only by controlling heat energy as a color source. 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.
