  An illumination device 10 according to an embodiment of the present invention will be described with reference to FIG. The illumination device according to an embodiment of the present invention includes a long first light emitting unit 100 and a long second light emitting unit 200.

  The first light emitting unit 100 and the second light emitting unit 200 each have a main surface (for example, a rectangle or a parallelogram) that extends in the X direction that is the longitudinal direction and the Y direction that is the short direction. The main surface refers to the main surface of the light emitting unit. In one embodiment, the light emitting unit has a shape that expands in a thick flat plate shape, and in this case, a surface (front surface or back surface) that expands in a flat plate shape can be referred to as a main surface. In one embodiment, the light emitting unit includes a flat substrate and a light source provided on the substrate. In this case, the substrate surface (front surface or back surface) can be called a main surface. The longitudinal direction of the substrate surface corresponds to the X direction, and the short direction (direction perpendicular to the longitudinal direction) of the substrate surface corresponds to the Y direction. Moreover, the surface in which the light source was provided among light emitting units can also be called a main surface. Furthermore, the light emitting unit can be provided on the mounting surface of the housing, and the surface of the light emitting unit along the mounting surface can also be called a main surface. FIG. 1 shows the appearance of the first light emitting unit 100 and the second light emitting unit 200 as seen from the main surface side.

  The first light emitting unit 100 and the second light emitting unit 200 have end portions in the longitudinal direction connected to each other. In FIG. 1, a first light emitting unit 100 and a second light emitting unit 200 are connected in series and arranged in a straight line. Further, the first light emitting unit 100 has a first end 161 and a second end 162 which are ends in the longitudinal direction of the first light emitting unit 100. Further, the second light emitting unit 200 has a first end 261 and a second end 262 which are end portions in the longitudinal direction of the second light emitting unit 200. In the example of FIG. 1, the first end 161 of the first light emitting unit 100 is connected to the second end 262 of the second light emitting unit 200.

  The first light emitting unit 100 and the second light emitting unit 200 are connected to each other through a regulating mechanism. The restricting mechanism has a shape that restricts relative movement of the first light emitting unit 100 and the second light emitting unit 200 in the short direction (Y direction). For example, the regulating mechanism fixes the relative positional relationship between the first light emitting unit 100 and the second light emitting unit 200 so that the first light emitting unit 100 and the second light emitting unit 200 do not move relatively. can do. In one embodiment, the first light emitting unit 100 and the second light emitting unit 200 have a predetermined length (length in the longitudinal direction), a predetermined width (length in the short direction), and a predetermined thickness. It is a substantially planar member. In such an embodiment, the regulating mechanism can regulate relative movement of the first light emitting unit 100 and the second light emitting unit 200 in the width direction, for example. In one embodiment, the regulating mechanism can fix the relative positional relationship such that the first light emitting unit 100 and the second light emitting unit 200 are in contact with each other.

  Hereinafter, an example of the restriction mechanism will be described with reference to FIG. FIG. 2 is an external view from the main surface side of the connecting portion of the first light emitting unit 100 and the second light emitting unit 200 in one embodiment. 2 is formed at the protrusion 110 formed at the first end 161 of the first light emitting unit 100 and the second end 262 of the second light emitting unit 200. And an engaging portion 210 that engages with. The protruding portion 110 and the engaging portion 210 are configured such that the side surface of the protruding portion 110 comes into contact with the side surface of the engaging portion 210 when the protruding portion 110 and the engaging portion 210 are engaged or relatively moved in the direction intersecting the longitudinal direction. be able to. For example, the protruding portion 110 and the engaging portion 210 can be configured such that side surfaces in the short direction face each other when engaged. Further, the projecting portion 110 and the engaging portion 210 can be configured such that the side surfaces in the short-side direction come into contact with each other when they are engaged or move relatively in the direction intersecting the longitudinal direction. According to such a regulation mechanism, when the end portions of the first light emitting unit 100 and the second light emitting unit 200 are connected to each other, it is possible to suppress positional deviation in the short direction. In FIG. 2, the left-right direction corresponds to the longitudinal direction (length direction), the up-down direction corresponds to the short direction (width direction), and the front-rear direction corresponds to the thickness direction. When such a configuration is used, it is not necessary to use an adhesive to connect the first light emitting unit 100 and the second light emitting unit 200, and even in this case, positional deviation between the light emitting units can be suppressed. . Even when the light emitting units are obliquely displaced, it can be said that there is a displacement in the Y direction when the Y component is present when the displacement direction is decomposed into an X component and a Y component. That is, in one embodiment, the regulating mechanism can suppress the positional deviation (relative movement) of the light emitting units in the direction including the component in the Y direction (short direction).

  Thus, in one embodiment, the first light-emitting unit 100 and the second light-emitting unit 200 each have a shape (for example, a protruding portion 110 and an engaging portion 210) on the main surface. By such a shape, that is, by connecting through the main surface end portion which is not straight, the relative movement in the short direction (Y direction) is restricted. In one example, the first light emitting unit 100 has a protruding end portion of the main surface at the connection portion, and the second light emitting unit 200 has the first light emitting unit end portion of the main surface at the connecting portion. It has a shape that engages with 100 protruding shapes.

  Another example of the restriction mechanism will be described with reference to FIG. FIG. 3B is an external view from the main surface side of the connecting portion of the first light emitting unit 100 and the second light emitting unit 200 in another embodiment. In FIG. 3B, the projecting portion 110 and the engaging portion 210 constituting the regulating mechanism each have a key shape and are engaged with each other. In this example, when the protruding portion 110 and the engaging portion 210 are engaged, the side surfaces in the short direction contact each other, and the side surfaces in the longitudinal direction also contact each other. According to such a configuration, when the ends of the first light-emitting unit 100 and the second light-emitting unit 200 are connected to each other, positional displacement in the short direction can be suppressed, and in the longitudinal direction. It is also possible to suppress the positional deviation.

  Another example of the restriction mechanism will be described with reference to FIG. FIG. 3B shows a connection portion of the first light emitting unit 100 and the second light emitting unit 200 in another embodiment. However, FIG. 3C shows a connection portion before being connected to each other. In FIG. 3C, the protruding portion 110 constituting the regulating mechanism is a protruding portion having a shape protruding from the end facing surface of the first light emitting unit 100 in the connecting portion. Further, the engaging portion 210 constituting the regulating mechanism has a shape recessed from the end facing surface of the second light emitting unit 100 in the connecting portion, and is a concave portion that engages with the convex portion of the first light emitting unit 100. It is. That is, each of the first light emitting unit 100 and the second light emitting unit 200 has a shape (for example, the protruding portion 110 and the engaging portion 210) on the end facing surface. By such a shape, that is, by connecting through an end facing surface that is not flat, relative movement in the short direction (Y direction) is restricted. As shown in FIG. 3C, the second light emitting unit 200 further has a convex portion 280 on the end facing surface, and the first light emitting unit 100 further engages with the convex portion 280 on the end facing surface. You may have the recessed part 190 to do.

  Still another example of the restriction mechanism will be described with reference to FIG. FIG. 3A is an external view from the main surface side of the connection portion of the first light emitting unit 100 and the second light emitting unit 200 in a further embodiment. In FIG. 3A, the restriction mechanism is formed by a connecting portion 164, a connecting portion 163, and a connecting portion 263. The connecting portion 164 is a connecting member that connects the first light emitting unit 100 and the second light emitting unit 200. The connection portion 163 is provided at the first end portion 161 of the first light emitting unit 100 and is connected to the connection portion 164. The connecting portion 263 is provided at the end of the second light emitting unit 200 and is connected to the connecting portion 164.

  In one embodiment, as shown in FIG. 3A, the connecting portions 163 and 263 are locking holes provided at the ends of the first light emitting unit 100 and the second light emitting unit 200. In such connection portions 163 and 263, the end portion of the coupling portion 164 can be inserted and fixed. According to such a structure, the distance between the connection parts 163 and 263 can be fixed. Accordingly, by connecting the first light emitting unit 100 and the second light emitting unit 200 using the connecting portion 164 so that the first end portion 161 and the second end portion 262 are in contact with each other, Misalignment can be suppressed.

  In FIG. 3A, there are two connecting portions 164 and two connecting portions 163 and 263, respectively, but the number thereof is not particularly limited. Moreover, the connection method of the connection part 164 and the connection parts 163 and 263 is not particularly limited. For example, the connecting portion 164 may be a strip-shaped metal strip, or may have another material or shape.

  Specific configurations of the first light emitting unit 100 and the second light emitting unit 200 are not particularly limited. For example, the first light emitting unit 100 and the second light emitting unit 200 may be the same light emitting unit. Further, the first light emitting unit 100 and the second light emitting unit 200 may have different lengths in the longitudinal direction. By preparing and connecting light emitting units having different lengths, light emitting units having various lengths can be realized. In one embodiment, in order to facilitate connection, the end surface at the first end 161 of the first light emitting unit 100 is the same size as the end surface at the second end 262 of the second light emitting unit 200. have.

  In one embodiment, the long first light emitting unit 100 includes a long first substrate 151 and a first light source group 152 provided on the substrate of the first substrate 151. The long second light emitting unit 200 includes a long second substrate 251 and a second light source group 252 provided on the second substrate 251. Here, the first substrate 151 and the second substrate 251 can be connected on the same surface so that end portions in the longitudinal direction face each other. For example, the first substrate 151 and the second substrate 251 can be connected so that the surfaces of the substrates are aligned on the same plane. In addition, the first substrate 151 and the second substrate 251 can be disposed on the same surface of the support member.

  In the example of FIG. 1, the first substrate 151 and the second substrate 251 are connected via a regulating mechanism so that the end portions in the longitudinal direction face each other. For example, the first substrate 151 can have the protrusion 110, and the second substrate 251 can have the engagement portion 210. In addition, the first substrate 151 may include a connection portion 163, and the second substrate 251 may include a connection portion 263. In such a configuration, the restricting mechanism restricts relative movement in the short direction between the first substrate 151 and the second substrate 251 along the first substrate 151 and the second substrate 251. can do.

  The first light source group 152 and the second light source group 252 include a plurality of light sources. The types of light sources included in the first light source group 152 and the second light source group 252 are not particularly limited. For example, the light source may be an LED (light emitting diode) or another light emitting element. In one embodiment, the first light source group 152 may be an LED array in which a plurality of LEDs are arranged in the longitudinal direction of the first substrate 151. The second light source group 252 may be an LED array in which a plurality of LEDs (light emitting diodes) 252 are arranged in the longitudinal direction of the second substrate 251.

  In one embodiment, the first light emitting unit 100 has a second end 162 that is opposite to the first end 161 that is the end connected to the second light emitting unit 200. The amount of emitted light is larger. Although the second light emitting unit 200 exists on the first end portion 161 side, there is no adjacent light emitting unit on the second end portion 162 side, and thus the amount of light emitted tends to be insufficient on the second end portion 162 side. . On the other hand, by increasing the light emission amount on the second end portion 162 side, it becomes easy to realize a uniform light projection amount over the entire longitudinal direction. As a specific example, such a configuration can be realized by making the arrangement density of the light sources on the second end portion 162 side higher than that on the first end portion 161 side. For example, in the example of FIG. 1 in which LEDs are used as the light source, the LED arrangement density on the second end portion 162 side is higher than that on the first end portion 161 side. Similarly, the second light emitting unit 200 also emits more light on the opposite first end 261 side than on the second end 262 side connected to the first light emitting unit 100. Can be configured.

  In the illuminating device according to the present embodiment, it is possible to suppress relative displacement between the first light emitting unit 100 and the second light emitting unit 200 in the direction intersecting the longitudinal direction. For this reason, when producing a longer illuminating device by arranging two or more light emitting units, it is possible to make the light intensity distribution on the irradiated object close to a desired distribution. Moreover, it becomes easy to arrange the 1st light emission unit 100 and the 2nd light emission unit 200 correctly along a longitudinal direction by using a control mechanism. For example, as illustrated in FIG. 1, in one embodiment, the lighting device has a structure in which a first light emitting unit 100 and a second light emitting unit 200 are provided in a housing (outer support member 14). Such an illumination device can be manufactured by arranging the first light emitting unit 100 and the second light emitting unit 200 on the surface of the housing. At this time, by using the restriction mechanism, it is easy to dispose the first light emitting unit 100 and the second light emitting unit 200 so as not to deviate in the direction intersecting the longitudinal direction. In addition, the 1st light emission unit 100 and the 2nd light emission unit 200 can be further fixed to a housing | casing using fixing members, such as a screw.

  Here, the lighting device including two light emitting units has been described. However, the number of light emitting units included in the lighting device is not particularly limited. For example, as illustrated in FIG. 1, the lighting device may include a third light emitting unit 300 and a fourth light emitting unit 400 in addition to the first light emitting unit 100 and the second light emitting unit 200. Here, the third light emitting unit 300 and the fourth light emitting unit 400 may have the same configuration as the first light emitting unit 100 and the second light emitting unit 200. For example, the third light-emitting unit 300 and the fourth light-emitting unit 400 may be connected to each other at their longitudinal ends via a regulating mechanism that regulates relative movement in a direction intersecting the longitudinal direction. Good. In addition, the lighting device may have a structure in which three or more light emitting units are connected. In this case, three or more units may be connected to each other via a restriction mechanism that restricts relative movement in the direction intersecting the longitudinal direction.

  Such an illumination device can be used as an illumination device for a line sensor device. Below, a line sensor apparatus provided with the illuminating device which concerns on this embodiment is demonstrated. A line sensor device according to an embodiment includes a housing, a lighting device according to the present embodiment, a lens array, and a line sensor. Hereinafter, an example of the line sensor device will be described with reference to FIG. 1 corresponds to a top view of the line sensor device shown in FIG.

  FIG. 4 is a perspective view for explaining the structure of the line sensor device 1 according to the embodiment. In order to facilitate understanding of the structure, an X axis, a Y axis, and a Z axis that are orthogonal to each other are shown in the drawing. Hereinafter, the X-axis direction may be referred to as a direction in which the inner support member 12 sandwiches the rod lens array 11 or simply as a sandwiching direction. Further, the Y-axis direction may be referred to as the optical axis direction of the rod lens array 11 or simply the optical axis direction. Further, the Z-axis direction may be referred to as the arrangement direction of the rod lens array 11 or simply the arrangement direction. Further, the line sensor device 1 has a long structure extending in the Y direction.

  In the present specification, the expression indicating the direction is used to indicate a relative positional relationship. For example, expressions such as “right” and “right side” correspond to the + X direction, and expressions such as “left” and “left side” correspond to the −X direction. For example, expressions such as “upper” and “upper” correspond to the + Z direction, and expressions such as “lower” and “lower” correspond to the −Z direction.

  The line sensor device 1 includes an outer support member 14. The outer support member 14 has a long shape extending in the arrangement direction, is disposed so as to sandwich two inner support members 12L and 12R described later, and supports the two inner support members 12L and 12R. In one embodiment, the outer support member 14 corresponds to a housing in the line sensor device 1, and each element is fixed directly or indirectly to the outer support member 14. In the example of FIG. 5, the outer support member 14 has a mirror image symmetrical shape.

  The illumination device 10 included in the line sensor device 1 irradiates light on a subject to be measured. The configuration of the illumination device 10 is as already described. The illuminating device 10 has a long shape, and can be disposed on at least one of the long outer support members 14. FIG. 2 shows such an example, and the two illuminating devices 10 are fixed to inclined surfaces formed on the inclined portions 141Le and 141Re of the outer support member 14, respectively. With such a configuration, the long illuminating device 10 can irradiate a subject (not shown) that can be disposed above the rod lens array 11 with light. Further, a light-transmitting plate material (not shown) such as a glass plate can be provided between the subject and the line sensor device 1. The illumination device 10 can be provided above the rod lens array 11. This prevents a shadow from being generated when the illumination device 10 irradiates the subject with light.

  The lens array included in the line sensor device 1 collects light emitted toward the subject from the illumination device 10 and guides it to the line sensor 13. In the example of FIG. 4, the rod lens array 11 is used as the lens array. The line sensor device 1 can determine the amount or color of light from the subject by detecting the light collected by the rod lens array. For example, the color, reflectance, or transmittance of a subject can be measured by detecting light reflected by the subject or transmitted through the subject. As an example, the line sensor device 1 can read an image recorded on a recording medium (for example, paper).

  The rod lens array 11 includes a plurality of rod lenses arranged in a predetermined direction (Y direction in the present embodiment). Each rod lens is arranged side by side with the light incident surface in the Z direction so that the optical axes are parallel. That is, the rod lens array 11 has a long structure extending in the arrangement direction. With such a configuration, a long linear region on the subject passing above the rod lens array 11 can be measured at a time. In the present embodiment, the rod lenses are arranged in one row, but two or more rows of rod lenses may be arranged. Although not shown in the figure, the rod lens array 11 may have a frame that accommodates the arrayed rod lenses therein.

  The line sensor 13 included in the line sensor device 1 detects light collected by the lens array. That is, the line sensor 13 can detect light that is irradiated by the illumination device 10 and reflected by the subject or transmitted through the subject. The line sensor 13 is fixed on the optical path of the rod lens array 11 so as to receive the light collected by the rod lens array 11. In the present embodiment, the line sensor 13 has a configuration capable of detecting light collected by the long rod lens array 11 at a time. In the present embodiment, the line sensor 13 has a long structure extending in the arrangement direction (Y direction) of the rod lens array 11. For example, the line sensor 13 can have a structure in which a plurality of photoelectric conversion elements (for example, photodiodes) are arranged in the arrangement direction (Y direction) of the rod lens array 11. As the line sensor 13, for example, a CCD or CMOS sensor can be used. The configuration of the line sensor 13 is not particularly limited. For example, the line sensor 13 may be an area sensor in which a plurality of photoelectric conversion elements are arranged in a matrix or a staggered pattern. Further, as the photoelectric conversion element, other light detection elements such as a PIN sensor or a MIS sensor may be used instead of the photodiode.

  In the example of FIG. 4, the rod lens array 11 is fixed so as to be sandwiched between two inner support members 12L and 12R. The line sensor 13 is directly or indirectly fixed to at least one of the two inner support members 12L and 12R. Each of the two inner support members 12L, 12R has a long structure extending in the arrangement direction. The outer support member 14 supports the two inner support members 12L and 12R, and thus the rod lens array 11 and the line sensor 13 are also fixed to the outer support member 14 which is a casing.

  The line sensor device 1 may have other configurations. For example, the line sensor device 1 illustrated in FIG. 4 includes mounting boards 16 and 17 that transmit the detection result of the line sensor 13 to the outside and supply power to the line sensor 13 or the lighting device 10. .

  The line sensor device 1 according to the present embodiment can be used as follows. For example, the illumination device 10 irradiates the subject with light while the subject is scanned relative to the line sensor device. The reflected light from the subject is collected by the rod lens array 11 and detected by the line sensor 13. Thereafter, the mounting boards 16 and 17 generate a signal based on the detection result by the line sensor 13 and output the signal to the outside. The type of signal output to the outside is not particularly limited, and examples thereof include image data indicating an image of a subject (an image on a recording medium, etc.), a signal indicating a deviation from a reference value of a detection result, and the like. As a specific example, a detection surface (for example, a surface on a light-transmitting plate member) is provided above the line sensor device 1, and the line sensor 13 detects light while moving the recording medium on the detection surface, thereby recording. The medium can be read. In the example of FIG. 4, the line sensor 13 detects reflected light from the subject. However, the line sensor 13 may detect transmitted light that is emitted from the illumination device 10 to the subject and transmitted through the subject.

  Such a line sensor device can be used as a component of a reading device or a recording device. FIG. 5 shows an example of a reading device 2 and a recording device 3 that include the line sensor device 1.

  The reading device 2 includes a line sensor device 1 and output means for outputting read data obtained by the line sensor device 1. The output means can generate a signal based on the detection result by the line sensor 13 and output the read data to the outside. For example, the mounting boards 16 and 17 described above can be used as output means.

  The recording device 3 includes a reading device 2, a recording unit 3 a that performs recording on a medium based on a result of reading by the reading device 2, and a conveyance unit that conveys the medium. The recording means 3a can record characters or images on the medium P (for example, paper) by an arbitrary method such as an ink jet method or an electrophotographic method. Further, as the conveying means, a conveying roller 4 that conveys the medium from upstream to downstream can be used. In one embodiment, the transport unit may move the recording unit 3a with respect to the medium, or may move both the medium and the recording unit 3a. In one embodiment, the recording device 3 can perform a copy process. In this case, the recording unit 3a records an image read by the reading device 2 on a medium. In one embodiment, the recording apparatus 3 can perform feedback control. For example, the reading device 2 can read the medium after the recording is performed by the recording unit 3 a and transmit the read data to the recording device 3. Based on the read data, the recording apparatus 3 can confirm the recording state on the medium, and can control the recording parameters at the next recording.

  As a specific example, a configuration in which the reading device 2 reads the medium P and the recording unit 3a performs recording on the medium P after being read by the reading device 2 based on the read data will be described. To do. For example, the recording position on the medium P by the recording unit 3a can be controlled based on the result of reading the medium P by the reading device 2. Further, based on the result of reading the medium P by the reading device 2, the recording parameters on the medium P by the recording unit 3a can be controlled. Furthermore, the recording means 3a can record information (for example, character information or graphic information) based on the result of reading the medium P by the reading device 2 on the medium P.

  For example, the reading device 2 can read a mark attached to the medium P. In one embodiment, the medium P is previously provided with an alignment mark used for positioning during recording. For example, the reading device 2 may detect a deviation from the reference position of the medium P based on the read position by reading the alignment mark, and may transmit the read data to the recording unit 3a. The recording unit 3a can record a character or an image at a more accurate position by adjusting the recording position based on the deviation of the medium P from the reference position. According to the present embodiment, for example, when recording is performed on both surfaces of the medium P, the recording positions on the front surface and the back surface can be more accurately matched. In addition, for example, when multiple recording is performed on a medium P in a plurality of steps (multiple printing), characters or images in each step can be recorded at a more accurate position. Overlapping of recorded characters or images can be prevented. As the shape of the alignment mark, for example, a + (cross) mark, a circle (circle) mark, or the like may be used.

  As another example of the mark, the medium P may have a barcode. In this case, the medium P can have a different barcode for each type (size, material, color, etc.). The reading device 2 reads the bar code and transmits information on the type of the medium P as read data to the recording unit 3a, so that the recording unit 3a can perform recording according to the type of the medium P. For example, the recording unit 3a may control recording parameters at the time of recording (darkness or color of characters or images) according to the type of the medium P. For example, the recording unit 3 a may record information such as a product name on the medium P according to the type of the medium P. Further, the recording unit 3a may record information corresponding to the barcode on the medium P. As an example, the recording unit 3a can print the product name corresponding to the barcode on the paper on which the barcode is printed.

  The reader 2 may read an entry field (blank) provided on the medium P as another example of the mark. In one embodiment, the reading device 2 reads the position of the entry field provided on the medium P, and transmits the read data to the recording means 3a. The recording unit 3a records characters so as to fit in the entry field of the medium P based on the read data. With such a configuration, the recording means 3a can record characters and the like in accordance with the position of the entry column of the medium P, so that the printed characters can be prevented from protruding from the entry column.

  As another example, the reading device 2 may read information on the medium P itself such as medium position information or medium color information. Examples of the information on the medium P itself include the position, width, angle, or color of the edge of the medium P. In one embodiment, the reading device 2 reads the leading end position of the medium P in the transport direction, and transmits the read data to the recording unit 3a. The recording unit 3a can record an image or the like at a more accurate position by controlling the time or the like to start recording of a character or an image on the medium P based on the read data. The recording unit 3a can perform so-called borderless printing by starting recording of characters, images, and the like from the leading end position of the medium P. When performing borderless printing, the reading device 2 may read not only the front end position of the medium P but also both side end positions and rear end positions. Thereby, borderless printing can be performed more accurately. In one embodiment, the reading device 2 reads a fold or a chip (hereinafter referred to as a fold or the like) of the medium P, that is, a difference from the original shape of the medium P, and uses the read result as read data. It transmits to the recording means 3a. The recording means 3a can record a mark indicating that the medium P is defective when the medium P is broken. Thus, when recording is performed on the large amount of medium P by the recording unit 3a, the operator can easily identify defective products from the large amount of medium P. Furthermore, in one embodiment, the reading device 2 determines the type (size, material, color, etc.) of the medium P and transmits the result to the recording means 3a as read data. The recording unit 3a can perform recording according to the type of the medium P based on the read data. For example, when the medium P is paper, the recording unit 3a prints by adjusting the density of characters or images according to the paper quality, or prints a pattern according to the color according to the paper color. You can do it.

  Note that the reading device 2 and the recording device 3 can communicate with each other by a wired connection or a wireless connection. Further, the medium P may be a sheet or a continuous paper.
