The read data is sent to a bidirectional shift register 14 from a shift register 13. The shift direction of the register 14 is controlled by driving a winding motor and a pay-off motor and the read data corrected into a forward image is sequentially recorded on a thermosensitive recording paper sheet 4 by using a thermal head 15. Thus, the recording onto plural number of sheets is attained in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a recording device capable of recording image information written on a sheet member by a recording means.
- <Prior art> Conventionally, the recording of image information written on a blackboard or the like at meetings, etc. has been done manually, resulting in problems such as transcription errors and loss of time.

Therefore, in recent years, so-called electronic whiteboard devices have been proposed that are equipped with the above-mentioned image information recording function (Japanese Patent Laid-Open No. 1983-250429).
Publications, etc.).

<Problems to be Solved by the Invention> However, the conventional electronic blackboard device is composed of a non-writing/displaying area made of a plastic sheet or the like with the same width as a normal blackboard, and a casing of the sheet. The problem was that it required the same size as a blackboard, and was difficult to move, so it could only be used in a specific location.

<Means for solving the problem> Therefore, the present applicant constructed a writable sheet so that it could be stored in the main body of the device, and provided a reading means for reading the image information on the sheet, and a reading means that responds to signals from the reading means. proposed an apparatus that is equipped with a recording means for recording on a recording medium, and is capable of recording image information written on a sheet with the recording means (Japanese Patent Application No. 34774/1982).

Unlike conventional electronic whiteboards, the above-mentioned device has the advantage that it is portable and can also be used on a desk.

The present invention is a further development of the above-mentioned device, and aims to provide a recording device that is capable of reading and recording image information on a sheet both when the sheet is fed out and stored. .

The means for this purpose includes a writable sheet member, a moving means for reciprocating the sheet member, a reading means for reading image information on the sheet member, and data from the reading means in the moving direction of the sheet member. The present invention is characterized in that it is provided with at least one of a storage means that can be rearranged according to the requirements, and an interface that outputs the output from the storage means to a recording medium or to another recording means.

<Operation> According to the above means, it is possible to draw out the sheet member and write image information on its surface, and the written information is read by the reading means when the sheet member moves back and forth. When this data is transmitted to the recording means as written data, if the sheet member is moved in the forward direction and the image information is read, the read data is transmitted as is, and if the sheet member is moved in the reverse direction and read, it is read. The data is rearranged by the storage means and transmitted to the recording means.

<Example> Next, an embodiment of the present invention to which the above means is applied will be described.

FIG. 1 is an external perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line CC in FIG.

Incidentally, the recording apparatus of this embodiment has a recording means for receiving and recording image information from a reading means.

In the figure, 1 is a writable sheet member,
One end thereof is fixed to a winding shaft 2, and it is wound onto this winding shaft 2 when not in use. This sheet member 1
forms a writing surface on which image information is written by pulling out in the direction of arrow a.

In addition, when reading and simultaneously recording the image information written on the sheet member 1, by selecting r copy mode j on the operation panel 3, the sheet member 1 is read while being wound inside the device at a constant speed. It is possible to record on recording paper 4, which is a recording medium. Further, this reading is similarly possible when the sheet member 1 is once wound up and then unwound at a constant moving speed. Incidentally, when there is no need to record the image information on the sheet member 1, it is possible to switch to an operation that only stores the sheet member 1 by selecting "storage mode J" on the operation panel 3.

Now, when writing image information on the sheet member 1, hold the free end of the sheet member 1 and pull it out in the direction of arrow a to form an image writing surface, and write a predetermined image on the surface with a pen or the like.

The image information written on the sheet member 1 as described above is read by the reading sensor 5 when the sheet member 1 is wound up and fed out. Here, the configuration for winding up the sheet member 1 is such that a winding roller 6 driven in the direction of the arrow by a motor (not shown) and a driven roller 7 that follows this winding roller 6 slide between it and the sheet member l. Both rollers 6 are pressed together with moderate contact pressure to prevent
The sheet member 1 is wound up by the cooperative action of .degree.7. At this time, the winding shaft 2 is driven to rotate by frictional transmission with a drive roller 8 which rotates at a faster circumferential speed than the winding roller 6.

In the above configuration, the sheet member 1 is wound up by the operation of the motor, which causes the take-up roller 6 to rotate, and the drive roller 8 and the take-up shaft 2 to rotate with some slippage. The sheet member 1 is now wound up on the winding shaft 2 without any slack and stored in the apparatus main body 9.

Further, the structure for feeding out the sheet member 1 is a feeding roller 10 which is driven and rotated in the direction of arrow C by a motor (not shown).
and a driven roller 11 that follows this feeding roller 10.
The rollers 10 and 1 are pressed against the sheet member 1 with an appropriate contact pressure to prevent slippage, and the sheet member 1 is fed out by the cooperative action of both rollers 10 and 11.

The take-up roller 6 and the feed roller 11 are provided with, for example, a one-way clutch, so that when one roller is driven to rotate, the other roller idles.

Further, the sheet member 1 is made of a material having a light transmittance that enables reading by a light transmitting type, and when the sheet member 1 is wound up or unwound, it is irradiated with light from a light source 12 such as a fluorescent lamp. The transmitted light is received by a light receiving cell 5a of a reading sensor 5 disposed close to the back surface of the sheet member 1, and the image information on the sheet member 1 is sequentially read.

Now, since the image information read as described above is read in opposite directions when the sheet is wound up and when it is fed out, the respective read data are in a mutually inverted state. Therefore, if the read data is transmitted as it is to the recording means and recorded, if the read data when winding up the sheet member 1 is recorded as shown in FIG. If the read data when the sheet member 1 is fed out is recorded as shown in (B), it will be recorded as an inverted image that is a mirror image of the normal rotation image.

In this embodiment, the read data of the inverted image is rearranged by the storage means, corrected to a normal image, and transmitted to the recording means. To explain its structure, as shown in FIG. 4, the read data is transmitted from the shift register 13 to the bidirectional shift register 14, and then transmitted to the thermal head as write data. Here, the shift register 13 inputs read data serially, and outputs the data to the bidirectional shift register 14 in parallel when data for - rows is input. Further, the bidirectional shift register 14 outputs the parallel input serially as write data to the thermal head by right-shifting or left-shifting.

Note that a shift clock is input to the shift registers 13 and 14, and data is shifted in accordance with the clock.

Further, the shift direction of the bidirectional shift register 14 is controlled by a shift control signal, which is controlled by driving the take-up motor and the pay-out motor. In other words, when the winding motor is driven (when winding up a sheet), the left shift control signal is transmitted and data is shifted to the left, and when the unwinding motor is driven (when the sheet is being fed out), the right shift control signal is transmitted. The data is shifted to the right and output.

The data (normal rotation image) read when winding up the sheet member 1 as described above is shifted to the left and output as is. On the other hand, the data (reversed image) read when the sheet member 1 is fed out is rearranged by changing the shift direction and shifting to the right, corrected to a normal rotation image, and then output.

Next, the data outputted from the storage means is sent as an image signal to the thermal head 15 shown in FIG. The information is sequentially recorded on the recording paper 4, and the recorded recording paper 4 is turned by the discharge roller 17 and discharged from the discharge port 18 in the direction of arrow d.

Note that the roll portion of the recording paper 4 is held on a support shaft 19,
When it is used up, it is replaced with a new one.

According to the above embodiment, the information written on the sheet member 1 can be read and recorded both during winding and unwinding of the sheet member 1, so that multiple sheets can be recorded in a short time and with a small storage capacity. It can be done.

In the above embodiment, read data was rearranged by changing the shift direction of the bidirectional shift register, but other configurations may be used as long as the memory capacity is one line or more6. For example, CPU (
The data may be processed by software using a central processing unit (central processing unit), or the data may be rearranged using an address generator that can be turned up or down.

Furthermore, in the above-described embodiment, the winding and unwinding of the sheet member 1 and the driving of the platen roller 16 were performed by separate motors, but these can be combined into one motor by providing a drive transmission system. It is also possible.

Furthermore, although the recording means used in the above-mentioned embodiments is thermal recording, it may also be thermal recording, inkjet recording, or the like.

Furthermore, even if the recording means is not provided in the main body of the apparatus as in the above-mentioned embodiment, for example, an interface with the recording means of another apparatus can be provided in the main body of the apparatus, and recording can be performed by the recording means of the other apparatus via the interface. You may also do so.

<Effects of the Invention> As described above, the present invention writes image information on a sheet member,
This sheet member is read by moving back and forth with respect to the reading means, and when the read data is a reverse image, it is rearranged and corrected to a normal image before being transmitted to the recording means. This makes it possible to record on multiple sheets in a short time and with a small storage capacity N2.
