Abstract

PURPOSE:To save the labor of operator by providing a section for recording an image at a first temperature, a section for erasing the image at a second temperature, a section for containing a recording medium, and means for carrying an erased recording medium to the containing section. CONSTITUTION:When a reversible thermal recording medium, i.e., a recording sheet, is inserted through an insertion port 18 for erasure, the recording sheet is carried on a carry roller 22 arranged in a carrying path 20 for erasure to an erasing head 24 where a recorded image is erased at an erasing temperature T2. Erased recording sheet is carried on a carrying roller 26 and a separating roller 28 arranged in the downstream of the erasure head 24 to a containing section 30 for recording. During the recording operation, a recording section 32 located at a lower part of recorder separates the recording sheets contained in the containing section 30 sheet by sheet by means of the separation roller 28 and a separation rubber 29. The recording sheet thus separated is then carried on a carrying path 34 for recording to a recording head 36 where the recording sheet is recorded at recording temperature T1 and subsequently discharged.

Then, when a recording sheet as a reversible thermosensitive recording medium is inserted from the erasing insertion opening 18, the recording sheet is sent to the erasing head 24 by the carrying roller 22 provided in the erasing carrying path 20. The erasing head 24 is composed of a heat roller using a halogen lamp, a plate heater in which a heating resistor is printed on a ceramic plate, and the like, and is configured to erase an image recorded at an erasing temperature T2. .

A transport roller 26 and a separation roller 28 are provided on the downstream side of the erasing head 24 in the erasing transport path 20, and are configured to transport the recording sheet to the recording storage section 30.

As shown in FIG. 2, the recording accommodating portion 30 is composed of an external cassette 30a and an internal cassette 30b, and recording sheets are accommodated in the internal cassette 30b. And the external cassette 30a
A spring 31 is arranged between the internal cassette 30b and the internal cassette 30b, and is configured to urge the internal cassette 30b upward.

A recording unit 32 is arranged at the bottom of the device. Then, the recording unit 32 separates the recording sheets in the recording storage unit 30 one by one by the separation roller 28 and the separation rubber 29 during the recording operation, and the recording conveyance path 34.
It is configured to be conveyed to the recording head 36 through. The recording head 36 is configured to record the conveyed recording sheet at a recording temperature T1 and then eject the recording sheet.

The structure in the vicinity of the recording storage section 30 will be described with reference to FIG.

A pulse motor 38 is arranged in the vicinity of the recording storage section 30, and the pulse motor 38 is provided in the gear 4
The switching arm 46 and the pressing arm 48 are connected via 0, 42, and 44. The switching arm 46 is configured to switch between the erasing conveyance path 20 and the recording conveyance path 34 in accordance with the rotational position thereof, and the holding arm 48 is arranged in the internal cassette of the recording storage section 30 in accordance with the conveyance path switching. 30b is configured to be pressed or released against the biasing force of the spring.

Next, FIG. 5 shows the electrical construction of this embodiment.
Will be described with reference to.

The communication device 50 is connected to a telephone line and is configured to supply the received data to the control device 52 and to transmit the data supplied from the control device 52.

The reading device 54 includes the reading unit 10 and is configured to supply the read image data to the control device 52.

The erasing device 56 is configured to include the erasing section 16 and is configured to erase an image from a recording sheet.

The recording device 58 is configured to include the recording unit 32, and is configured to record the image data supplied from the control device 52 on a recording sheet.

The position detector 60 is configured to detect the switching state of the erasing conveyance path 20 and the recording conveyance path 34 by detecting the rotational position of the pulse motor 38.

Next, the operation of the facsimile apparatus of this embodiment will be described with reference to the flowchart shown in FIG.

First, in step ST1 (hereinafter referred to as ST1. The same applies to other steps).
The facsimile mode is determined. If it is determined that the reading mode is set, the reading operation is performed in ST2. For this reading operation, the document table 1
This is an operation in which the first document is read by the image sensor 10 and the image data is transmitted via the communication device 50, for example.

When it is determined in ST1 that the erase mode is set, in ST3 the position detector 60 is detected.
Thus, the switching state between the erasing conveyance path 20 and the recording conveyance path 34 is determined. If the recording conveyance path 34 is switched to the recording conveyance path 34 as shown in FIG.
The pulse motor 38 is rotated to rotate the switching arm 46 to open the erasing conveyance path 20 and close the recording conveyance path 34 as shown in FIG.
By rotating 8 to press the inner case 30b, the conveyed recording sheet is easily stored in the inner case 30b.
Then, in ST5, the erase operation is performed.

The erasing operation will be described. When the recording sheet inserted from the erasing insertion port 18 is conveyed by the conveying roller 22 to the erasing head 24 through the erasing conveying path 20, heat is applied to the recording sheet. The information on the recording sheet is erased. The recording sheet from which the image has been erased is accommodated in the inner case 30b of the recording accommodating portion 30 through the erasing conveying path 20 by the conveying roller 26 and the separating roller 28. In addition, as shown in FIG. 3, when it is determined in ST3 that the conveyance path 20 for erasing has been switched, the operation of ST5 is performed without performing the operation of ST4.

If it is determined in ST1 that the recording mode is set, in ST6, the position detector 60 is detected.
Thus, the switching state between the erasing conveyance path 20 and the recording conveyance path 34 is determined. Here, as shown in FIG. 3, when the conveyance path for erasure 20 is switched, in ST7,
The pulse motor 38 is rotated to rotate the switching arm 46 to open the recording conveying path 34 and close the erasing conveying path 20 as shown in FIG.
8 is rotated to release the pressing of the inner case 30b, and the urging force of the spring 31 presses the recording sheet in the inner case 30b against the separation roller 28. Then, in ST8, the recording operation is performed. To explain this recording operation,
The recording sheets are separated one by one by the separation roller 28 and the separation rubber 29, and pass through the recording conveyance path 34 to record the recording head 3
The image is recorded on the recording head 36 by the recording head 36 and discharged. This image corresponds to the image data received by the communication device 50, for example. When it is determined in ST6 that the recording conveyance path 34 has been switched as shown in FIG. 4, the operation of ST8 is performed without performing the operation of ST7.

[0026]

As is apparent from the above description, the recording apparatus using the reversible thermosensitive recording medium of the present invention has a structure in which the recording medium which has been erased is automatically stored in the recording storing portion. Therefore, the labor of the operator can be saved.
