However, after performing reading processing in a place different from the apparatus main body, it is connected to the apparatus main body. There is also a usage form in which image data stored in a memory is used for print output. Therefore, in the memory of the hand scanner, a state may occur in which image data that has already been printed out and image data that is not yet used for printing are mixed.

On the other hand, when reading processing is performed at a place different from the apparatus main body, a usage form in which image data is newly read and stored in the memory even when the data storage amount of the memory has reached a limit is assumed. . Therefore, some conventional hand scanners are capable of collectively deleting all image data stored in a memory in response to a predetermined operation by a user. In order to perform such an operation, it is necessary to provide an erasing key or the like, but hand scanners are strongly demanded to be lightweight and compact in terms of operability and the like. There is a restriction that you can not. Therefore, it is said that the number of keys not involved in the reading operation should be reduced as much as possible.

[0005]

However, according to the above-described conventional hand scanner, all image data can only be erased from the memory at once due to the limitation of the number of keys and the like. Even if there is image data left in the computer, it was forcibly deleted. In such a case, image data read for later print output is wasted, so convenient usability such as opening the memory while leaving the image data remaining in the memory without being printed out is demanded. It had been.

In the other hand scanner B, a control unit B1 is a circuit having a processor with a built-in program for controlling the entire operation of the scanner B. An interface function for exchanging data and various signals is provided. The memory B2 is a relatively high-speed readable / writable storage device such as a RAM or an EEPROM, for example, and temporarily stores a large amount of image data obtained from a plurality of original sheets and stores the image data in the device. It is provided for transferring and outputting to the main body A. Also, the memory B2
The power supply is backed up by a rechargeable battery or the like, and image data can be permanently stored and stored. The image reading unit B3 reads an original sheet to generate image data, and includes a line image sensor, an encoder, and the like. That is, the hand scanner B reads the image by the raster scan method by manual operation facing the document paper. The image data obtained by the reading process of the hand scanner B is

Note that the hand scanner B is provided with a start / stop key for notifying the control unit B1 of the start or stop of reading by the user, a data transfer key and a data erase key described later, and a display unit. Is merely provided with an LED for indicating an operation state or the like.

Briefly explaining the gist of the present invention,
When the hand scanner B is used while connected to the apparatus main body A, the image data obtained from the image reading unit B3 is usually transferred to the apparatus main body A via the memory B2 and output. Further, the image data is used for printing output in the printing unit 12 of the apparatus main body A, and the like. At this time, memory B
2, the image data transferred and output to the apparatus main body A for printing is still left. On the other hand, the device body A
When the hand scanner B is used in a place different from the above, the image data obtained from the image reading unit B3 will be
Is stored in the memory B2 for transfer and output. Therefore, in the memory B2 of the hand scanner B, the image data already transferred and output to the apparatus main body A (hereinafter, referred to as “output completed data”) and the image data not yet transferred and output (hereinafter, referred to as “output unfinished data”) are stored. ) Are mixed. Note that the output-completed data and the output-uncompleted data are
The processor of the control unit B1 that transfers and outputs the image data to the apparatus main body A can be distinguished by writing, as a flag, the already-outputted information that has been output for the corresponding image data.

When the amount of data stored in the memory B2 for storing image data reaches the limit in this way, the newly read image data cannot be stored in the memory B2. It is possible to delete image data from the memory B2.

On the other hand, only one erase key is provided due to restrictions on operability and the like. If all the image data stored in the memory B2 are collectively erased by a single key operation, the erase key is still printed. Unfinished output data that is not used for output is also erased and wasted. Therefore, by simply operating the erase key, the processor of the control unit B1 keeps the output-unfinished data as it is without erasing it from the memory B2, while erasing only the output-completed data from the memory B2.

The processor of the control unit B1 has a memory B
If only output-completed data is stored in 2, or conversely, only output-uncompleted data is stored,
All image data stored in the memory B2 is erased according to the operation of the erase key. Further, the processor of the control unit B1 erases all image data even when the operation of the erase key is continuously and repeatedly performed. On the other hand, when the operation of the erase key is performed immediately after the reading process, the processor of the control unit B1 erases only the image data just obtained by the reading process from the memory B2. Furthermore, the processor of the control unit B1 also supports an automatic erasing mode in which output completed data that has passed a predetermined time after transfer output is automatically erased from the memory B2.

That is, the processor of the control unit B1 includes an output-completed recording unit that records the output status of the image data that has been divided and stored in the memory B2 for each section that has already been output, and an output-completed recording unit. Output undetermined means for determining whether or not image data of a section not yet used for output still exists in the memory B2 based on the already-recorded information described in (1), and the output undetermined means corresponds to unsettled data output. If the determination result that the image data of the section exists in the memory B2 is obtained, even if a request to erase the image data of the memory B2 is accepted, the image data of the section corresponding to the unfinished data output remains. , A memory data erasing means for erasing only the already output image data from the memory B2.

Further, the processor, which functions as a storage medium by incorporating the program, stores the image data obtained by reading from the manuscript paper in a memory after dividing the image data for each reading process and storing the image data in the memory. A storage medium storing a program for controlling a simple operation type image reader capable of erasing image data from the memory while being able to output the image data to the other device. With respect to the image data that has been classified and stored, an output already-recorded program for recording the already-existing data output for each section that has already been output, and the already-output information based on the already-recorded information described by the output-recorded recording program, the output is still performed. An output unsettled determination program for determining whether or not image data of an unused section is present in the memory. And a request to erase the image data in the memory is received when the determination result that the image data of the section corresponding to the unfinished output of the data exists in the memory based on the output unsettled determination program is obtained. However, it is possible to realize a storage medium storing a program including a memory data erasing program for erasing only already output image data from the memory while leaving image data of a section corresponding to data output not yet completed. ing.

Next, the operation of the facsimile apparatus having the above configuration, particularly, the operation procedure for erasing data from the memory B2 of the hand scanner B will be described with reference to the drawings.

FIG. 2 is a flowchart showing an operation procedure of a reading process in the hand scanner B on the premise of performing the data erasing. As shown in FIG. It is determined whether or not the start key has been operated (S10). When the start key is operated, the processor determines that the reading of the document sheet has been started by the user.

When the start key is operated (S10:
YES), the processor performs an image reading process with one scanning movement as one section until a user operates a stop key described later (S11). In the one-section image reading process, the image data read by the raster scan method is sequentially stored in the memory B2 via the image reading unit B3.

In such one-section image reading processing, the processor determines whether the user has operated the stop key (S12).

When the stop key is operated (S12: Y
ES), the processor stores the image data obtained at the time of operating the stop key as one section in the memory B2 (S13).

Thus, one section of image data is stored in the memory B2.
After that, the processor stores the data stored in the memory B2 in response to the operation of the data transfer key by the user or the transfer control command from the apparatus main body A.
It is determined whether there is a transfer output request for the image data of the section (S14).

When there is a transfer output request (S14:
After determining that the image data exists in the memory B2 (S15: YES), the processor transfers and outputs one section of the image data stored in the memory B2 to the apparatus main body A in S13 (YES). S16). Thus, the device body A
The image data transferred and output is used for print output and the like, but is still stored and held in the memory B2 after the transfer output. Step S15 is executed as a particularly effective step when the data transfer key is operated regardless of the reading operation. When the data transfer key is operated a plurality of times in succession, the image data stored in the memory B2 is transferred sequentially from the latest one or the oldest one.

After transferring and outputting one section of image data as described above, the processor outputs "output already" indicating that the image data stored and held in the memory B2 has already been transferred and output after the transfer and output. Is written (S17). Specifically, the already-processed information is a flag in which information such as “already output” is written in bit units, and the image data in which the already-processed information of “already output” is written corresponds to the already-output data.

In the case of the normal mode, the processor which has completed the processing of S17 ends a series of operations relating to the reading processing. In the case of the automatic erasing mode, the processor executes the processing of S16.
It is determined whether or not a predetermined time has elapsed since the transfer and output of the image data (S18).

When a certain period of time has elapsed from the transfer output of the image data (S18: YES), the processor performs the operation based on the automatic erasing mode, in S17, the image data in which the already output information of "output already" is written, that is, the output already completed. The data is erased from the memory B2 (S19). Thus, even if the user has forgotten whether or not the printout has been completed, for example, for the already output data which has already been printed out by being transferred and output to the apparatus main body A, it is surely regarded as unnecessary data by the hand scanner. B can be automatically erased from the memory B2.

In S18, when a predetermined time has not elapsed from the transfer output of the image data in the automatic erasing mode (S18).
18: NO), the processor repeatedly performs the determination in S17 until a certain time has elapsed.

In S15, the image data is stored in the memory B2.
If not (S15: NO), the processor causes the buzzer or the like to issue an error notification that there is no image data to be transferred (S20).

In S14, if there is no transfer output request (S14: NO), the processor returns to S10 and returns to S10.
A series of processes up to 13 is repeated. As a result, the image data corresponding to the next section is read, and the image data is stored in the memory B2 for each section. Thus, the image data of each section stored in the memory B2 without the transfer output request is “output completed”.
Is handled as output unsettled data in which the already-seen information is not written.

If the stop key is not operated in S12 (S12: NO), the processor returns to S11 and continues the image reading process of one section until the stop key is operated.

If the start key is not operated in S10 (S10: NO), the processor jumps to S14 and determines whether or not the data transfer key is operated. As a result, when the data transfer key is operated without performing the image reading process, the subsequent processes are appropriately executed after the process of S15.

FIG. 3 is a flowchart showing an operation procedure of the data erasing process in the hand scanner B. As shown in FIG.
It is determined whether a predetermined time has elapsed from the reading process shown in the flowchart of FIG. 2 (S30).

After a lapse of a predetermined time from the reading process (S3
0: YES), the processor determines whether or not the user has operated the erase key with one push (S31).
The certain time elapsed after the reading process here is a considerable time during which the user who has completed the reading process can perform the next operation.

When the one-push operation is performed on the erase key (S31: YES), the processor determines whether or not the output-uncompleted data exists in the memory B2 (S3).
2). At this time, the processor refers to the already-written information written in the image data of each section as the criterion.

If the output-uncompleted data is present in the memory B2 (S32: YES), the processor deletes only the image data other than the output-uncompleted data from the memory B2 (S33).

Thereafter, the processor again determines whether or not the user has operated the erase key with one push (S34). Note that S34 may be a processor execution process that is performed only within a certain time after the erase key is first operated in S31.

When the one-push operation is again performed on the erase key (S34: YES), the processor erases all the image data remaining in the memory B2 at that time (S3).
5) After that, a series of operations related to the data erasing process ends. In other words, when the erase key is again pushed once following the one push operation of the erase key in S31, even if the output-uncompleted and output-completed image data are mixed in the memory B2 before the first key operation, All image data is erased from the memory B2 in response to two key operations.

In S34, if the one-push operation of the erase key is not performed again (S34: NO), the processor
A series of operations related to the data erasing process ends. As a result, the user can erase only unnecessary output completed data from the memory B2 while leaving unoutputted data in the memory B2 by one key operation.

In S32, if there is no output-completed data in the memory B2 (S32: NO), that is, if there is only unnecessary output-completed data in the memory B2, the processor skips to S35 and stores all image data in the memory B2. B2
Erase from

In S31, if the delete key is not operated by one-push operation (S31: NO) and the two-push operation is performed (S36: YES), the processor proceeds to S35.
And all the image data is collectively erased from the memory B2. Thereby, even if the image data that has not been output and the image data that has already been output are mixed in the memory B2,
All the image data can be erased from the memory B2. Here, the two-push operation refers to a case where a key operation is performed twice consecutively within a very short time, and the processing corresponding thereto is also simplified in the internal processing as compared with the processing from S31 to S35 described above. Be transformed into

In S36, when neither the one push operation nor the two push operation is performed on the erase key (S36: N
O), the processor ends a series of operations related to the data erasing process.

In S30, if the erase key is operated by one-push operation (S37: YES) without the lapse of a fixed time from the reading process (S30: NO), the processor stores the image of one section stored immediately after the reading process. Only data is erased from the memory B2 (S38). This allows the user to, for example, if the read operation fails,
In response to such a failure, only one section of the image data to be discarded can be erased from the memory B2 immediately after the reading failure.

If it is determined in S37 that the one-push operation has not been performed on the erase key until a predetermined time has elapsed from the reading process (S37: NO), the processor returns to S30 and repeatedly determines whether the time has elapsed.

Therefore, according to the hand scanner B having the above-described configuration and operation, when unsettled data not yet used for print output still exists in the memory B2, the user performs a one-push operation on the erase key, and the memory B2 Even if there is a request to erase the image data, the output-unfinished data is securely left in the memory B2, and only the already output image data can be erased from the memory B2. In other words, the memory B2 is opened by erasing the image data that has not already been printed out, and the image data required for the subsequent printout is left in the memory B2, thereby realizing convenient usability. At the same time, the memory can be utilized to the maximum extent by utilizing the free space generated after the data is erased.

In the above embodiment, the memory B2
The type such as the accumulated amount of image data and the output completed and output completed may be displayed on the LED or LCD provided in the hand scanner B. In that case,
Preferably, an LED advantageous for miniaturization and weight reduction is optimal.

In the above embodiment, only one key for erasing image data is provided. However, as long as operability is not impaired, a plurality of erasing keys corresponding to various requests may be provided. good.
