2. Description of the Related Art A facsimile apparatus has a function of reading image information of a document at a reading position by a reading means and transmitting or copying the image information to a predetermined destination. Then, when reading the original at the reading position, and conveys the document to a predetermined reading position on the basis of the detection information of the original detection sensor for detecting the front end and rear end of the document, the light from the light source to the document surface in this state And the image information on the document surface is read by a CCD or the like.

[0003] At this time, attempting to read without omission to image information before edge position and rear end position of the document, which will read the rear side of the front and rear than the previous end of the document due to variations in original detection sensor There is. Be read in this way the rear side than the front and rear than the previous end of the document, the portion having no normal document, there is no problem because the reading position is the same as the background of the document is in white, for example,
If the light source is downstream from the document reading position,
When the trailing edge of the document was read, a shadow was formed in a portion where the light from the light source did not reach due to the thickness of the document, and the portion was determined to be black despite no image information. Further, when the light source is upstream of the position read, it shadows the light does not reach portions of the light source had occurred by the thickness of the document when reading the front end of the document.

[0004] In this case, a problem that with a black streak before end and rear end of the document when copying out by copying occurs, a black streak before end and rear end of the document at the time of facsimile transmission occurs Will occur,
This phenomenon increased in proportion to the thickness of the document. To solve such problems, as well as do not load variations + alpha of original detection sensor when detecting the front edge of the document, the document detecting sensor when detecting the trailing edge of the original variation + alpha It is conceivable not to read.

In the present embodiment, the communication control unit and the plotter having the facsimile transmission function and the copy function are known, and therefore, the description is omitted.

A document detection sensor 10 is provided between the contact glass 1 and the reading roller 2. The document detection sensor 10 detects the front and rear ends of the document P and outputs a signal to control means (not shown). This control means controls the reading rollers 2 and 3 according to the output information of the document detection sensor 10 and the selection mode for copying and transmission.

In FIG. 1, the hatching at the rear end of the document P indicates a shadow generated at the rear end of the document P. FIG. 2A shows a portion where image information of the original P is read at the time of copying and transmission, and FIG. 2B shows a transfer sheet P1 when the original P is copied within this reading range. FIG. 4C is a diagram showing a recording sheet P2 showing a transmission result when a document is transmitted in the reading range.

Next, an image reading method according to this embodiment will be described with reference to the flowchart of FIG. After the power is turned on, it is determined whether the copy button is pressed or the send button is pressed (step S1). If the copy button is pressed, the conveyance motor is turned on (step S2), and the original is detected. Whether the sensor 10 is turned on, that is,
It is determined whether or not front end is detected in (step S3), O
If the answer is N, the counting of the transport amount of the document P is started.
(Step S4).

Next, when the count amount is L1 + a (where L1 + a
It is set to a distance obtained by subtracting the half of the amount of variation in the sensor 10 from the distance α from the document detecting sensor 10 to the reading before end reference position of the original P, a is set to the variation α substantially equal amounts) Is reached (step S5), reading of the image information on the lower surface of the document P by the reading means 9 is started, and the counting is ended (step S6). As a result, it is not performed read before end of the document P.

Next, it is determined whether or not the document detection sensor 10 has been turned off, that is, whether or not the trailing end of the document P has been detected (step S7).
Is started (step S8), the count amount becomes L2-b (where L2 is the distance from the document detection sensor 10 to the reference position of the rear end of the document P read).
Is set to a distance obtained by adding half the amount of the variation α, and b is set to an amount substantially equal to the variation α).
(Step S9) The reading is terminated, and the counting is terminated (Step S10). As a result, the rear end of the document P is not read.

Next, after the document P is discharged from the discharge section,
(Step S11) After waiting (Step S12), the next original P
Wait for copy or transmission of. As described above, at the time of copying, half of the variation α of the detection sensor 10 is not read at the front and rear ends of the document P, and therefore, as shown in FIG. Margins are formed.

On the other hand, if the facsimile transmission button is pressed (step S21), after turning on the conveyance motor (step S22), it is determined whether or not the document detection sensor 10 is turned on (step S23). If so, counting of the transport amount of the document P is started (step S24). Next, when the count amount reaches L1 (step S25), reading of the image information on the lower surface of the document P by the reading means 9 is started, and the counting is ended (step S26). As a result, forward read than previous end of the document P.

Next, it is determined whether or not the document detection sensor 10 has been turned off (step S27). If the document detection sensor 10 has been turned off, the counting of the transport amount of the document P is started (step S28). Is reached (step S29),
The reading is terminated, and the counting is terminated (step S10). As a result, the rear also read from the end after the original P. Next, the flow of steps S11 and S12 is executed.

As described above, at the time of facsimile transmission, half of the variation α of the detection sensor 10 is read at the front and rear ends of the document P, and therefore, as shown in FIG. All the information is written, and the recording paper P2 on which the streaks B are formed at the rear end is obtained.
Thus, in this embodiment, since the switched read before end position or trailing end position of the original P at the reading position of the original P at the time of transmission and time of copying, to reduce the reading of the front and rear ends of the document P at the time of copying As a result, it is possible to prevent an abnormal image from being formed in a portion where a shadow at the front and rear ends is generated, and it is also possible to increase the reading of the front and rear ends of the document P at the time of transmission and reliably transmit the document P to a predetermined destination. be able to. As a result, the influence of the shadow of the front and rear edges of the document P at the time of copying and transmission can be suppressed to prevent an abnormal image from occurring at the time of copying and transmission, and the usability of the facsimile apparatus can be improved. it can.

Further, in the present embodiment, when the original P is copied on roll paper, there is no break in the recording paper, that is, no shadow is generated. By setting, the length of the document and the length of the recording paper can be made substantially the same, and the filing of the recording paper can be improved. In this embodiment,
Since the light source 5 is provided downstream of the contact glass 1,
Since a shadow is generated only at the rear end of the document P, it is possible to prevent only the rear end of the document P from being read during copying, as shown in FIG. In this case, the value of a may be set to 0 in step S5 of the flowchart shown in FIG.

In this embodiment, the light source 5 is provided downstream of the contact glass 1. However, the present invention is not limited to this. The light source 21 is provided upstream of the contact glass 1 as shown in FIG. May be provided. In this case, since the shadow occurs before the end of the document P, it suffices to not read only the front end of the original P as shown in FIG. 5 (b) during copying. In this case, the value of b may be set to 0 in step S9 of the flowchart shown in FIG.

FIGS. 6 to 8 show an embodiment of the facsimile apparatus according to the third and fourth aspects of the present invention. In addition,
This embodiment is different from the above embodiment only in that the present embodiment is different from the above embodiment only in that it has a pressure plate for pressing the original against the contact glass and that the control means drives the reading rollers 2 and 3 in accordance with the halftone mode and the character mode. Are the same as those in the above-described embodiment.

In FIG. 6, reference numeral 31 denotes a pressing plate. The pressing plate 31 is urged toward the contact glass 1 by a spring 32, and when the document P is conveyed between the contact glass 1 and the pressing plate 31. The document P is pressed against the contact glass 1. Next, an image reading method according to the present embodiment will be described with reference to the flowchart of FIG.

In this embodiment, since the original P is pressed against the contact glass 1 by the pressure plate 31, shadows are hardly generated at the front and rear ends of the ordinary thin original P, but the original P becomes thicker. The more the shadow, the more the shadow is likely to occur. In this case, the presence or absence of a shadow can be easily determined by detecting the thickness of the document. However, if a sensor or the like for detecting the thickness of the document is provided, the mechanism becomes complicated and the cost increases. Would. For this reason, it is necessary to determine the thickness of the document without using a sensor or the like.

Considering how the thickness of the document P can be determined without using a sensor or the like, it can be determined that the document is thick especially when the document P is a photograph. In this case, when copying and transmitting a photograph, it is often used in a halftone mode. Therefore, in this embodiment, the reading position of the document P is switched between the halftone mode and the character mode, so that the reading position is switched according to the thickness of the document P.

Hereinafter, description will be made with reference to FIG. In the flowchart of FIG. 7, the values of L1, L2, a, b, etc. are the same as in the above embodiment. First, after the power is turned on, it is determined whether or not a copy button or a transmission button is pressed (step S31), and if it is pressed, it is determined whether or not a halftone mode is set (step S32). . When the halftone mode is selected, the conveyance motor is turned on (step S33), and it is determined whether or not the document detection sensor 10 is turned on (step S34). The counting of the amount is started (step S35).

Next, when the counted amount reaches L1 + a (step S36), reading of the image information on the lower surface of the original P by the reading means 9 is started and the counting is ended (step S37). As a result, it is not performed read before end of the document P. Next, the document detection sensor 10
It is determined whether or not the document has been fed (step S38). If it has been turned off, the count of the transport amount of the document P is started (step S39), and when the count reaches L2-b (step S40). Then, the reading is terminated and the counting is terminated (step S41). As a result, the rear end of the document P is not read.

Next, after the document P is discharged from the discharge section,
(Step S42), waits (Step S43), and returns to the next original P
Wait for copy or transmission of. As described above, in the halftone mode in which the document P is thick, since half of the variation α of the detection sensor 10 is not read at the front and rear ends of the document P, the document P is copied or transmitted as shown in FIG. A margin is formed at the front and rear ends of the transfer paper P3 or the recording paper P3.

On the other hand, when the mode is not the halftone mode, after the conveyance motor is turned on (step S51), it is determined whether or not the document detection sensor 10 is turned on (step S52).
When turned on, counting of the transport amount of the document P is started.
(Step S53). Next, when the count amount reaches L1 (step S54), reading of the image information on the lower surface of the document P by the reading means 9 is started, and the counting is ended (step S55). As a result, the document P is also read forward from the front end.

Next, it is determined whether or not the document detection sensor 10 has been turned off (step S56). If the document detection sensor 10 has been turned off, the counting of the transport amount of the document P is started (step S57), and the count amount becomes L2. Is reached (step S58),
The reading is terminated, and the counting is terminated (step S41). As a result, the document P is also read behind the rear end. Next, the flow of steps S42 and S43 is executed.

As described above, when the document P is in the thin character mode, the variation α of the detection sensor 10 at the front and rear ends of the document P
As shown in FIG. 8 (c), all the image information of the original P is written in the front-rear direction and the transfer paper P4 or the recording paper P on which the streaks B are formed at the rear end. Paper P4 is obtained. Thus, in this embodiment, since the switched read before end position or trailing end position of the original P at the reading position of the original P at the half-tone mode and character mode, it determines the thickness of the document P in existing equipment Thus, the influence of the shadows on the front and rear ends of the original P when copying and transmitting the thick original P in which shadows are likely to occur at the front and rear ends can be suppressed. For this reason, it is possible to prevent an abnormal image from occurring at the time of copying or transmission, and to improve the use performance of the facsimile apparatus.

Further, in this embodiment, since the light source 5 is provided downstream of the contact glass 1, a shadow is generated only at the rear end of the document P, so that the same as that of the document P shown in FIG. Alternatively, only the rear end may not be read. In this case, the value of a may be set to 0 in step S36 of the flowchart shown in FIG. Further, in this embodiment, an example in which the light source 5 is provided downstream of the contact glass 1 is shown, but a light source may be provided upstream of the contact glass 1 as in the above embodiment. In this case,
Because shadow occurs before the end of the document P, the halftone mode as shown in FIG. 5 (b) and may be so as not similarly read only the front end of the original P. In this case, the value of b is set to 0 in step S40 of the flowchart shown in FIG.
You can do it.
