Title: Image generating apparatus

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to an image generating apparatus, and more particularly, it relates to an image generating apparatus comprising an infrared communication portion set on an apparatus body performing printing for infrared communication of image data.  
      2. Description of the Background Art  
      An image generating apparatus such as a thermal transfer printer comprising an infrared communication portion (infrared communication element) set on an apparatus body performing printing for infrared communication of image data is known in general. Further, a portable telephone having a camera portion and an infrared communication portion (infrared communication element) capable of transmitting image data (photographic data) picked up with the camera portion to a thermal transfer printer is also known in general.  FIG. 12  is a perspective view showing an exemplary conventional thermal transfer printer and a portable telephone  110  having a camera portion  110   a  and an infrared communication element  110   b .  FIGS. 13 and 14  are sectional views showing communication between the conventional thermal transfer printer and the portable telephone  110  shown in  FIG. 12  respectively. The structures of the exemplary conventional thermal transfer printer and the portable telephone  110  having the camera portion  110   a  and the infrared communication element  110   b  are now described with reference to FIGS.  12  to  14 .  
      The exemplary thermal transfer printer has a printer body  101  capable of performing printing on the basis of image data, a paper feed tray  102  detachably mounted on the printer body  101  and an infrared communication element  103  for infrared communication of image data between the thermal transfer printer and the portable telephone  110 , as shown in  FIG. 12 . The printer body  101  includes a receiving hole  110   a  for receiving an ink sheet cartridge (not shown), an infrared communication hole  101   b  for exposing the surface of the infrared communication element  103  and a mounting portion  101   c  for mounting the infrared communication element  103  on the printer body  101 , as shown in  FIGS. 12 and 13 . The portable telephone  110  has the camera portion  110   a  capable of picking up images and the infrared communication element  110   b  for transmitting data of the images picked up with the camera portion  110   a  to the thermal transfer printer.  
      The infrared communication elements  103  and  110   b  of the printer body  101  of the thermal transfer printer and the portable telephone  110   b  correspond to the Ir-DA standard. The Ir-DA standard is an infrared communication standard set for allowing communication between products of various makers in infrared data communication. According to the Ir-DA standard, the beam spread angle is narrowed to ±15° on both transmission and receiving sides, in order to suppress interference between different apparatuses.  
      Data communication between the printer body  101  of the exemplary thermal transfer printer and the portable telephone  110  is now described. As shown in  FIG. 13 , the portable telephone  110  converts data of images picked up with the camera portion  110   a  to an infrared signal, so that the infrared communication element  110   b  transmits this signal. The transmitted infrared signal rectilinearly progresses at the beam spread angle of ±15°, and is received by the infrared communication element  103  of the printer body  101  of the thermal transfer printer. The thermal transfer printer converts the infrared signal received by the infrared communication element  103  to image data. The printer body  101  performs printing on the basis of the image data. The printer body  101  can also communicate with the portable telephone  110 , as shown in  FIG. 14 .  
      In the conventional thermal transfer printer shown in FIGS.  12  to  14 , however, it is difficult to communicate with the portable telephone  110  when the position or the direction of the infrared communication element  110   b  of the portable telephone  110  deviates from the infrared communication element  103  of the printer body  101  of the thermal transfer printer as shown in  FIGS. 15 and 16 , due to the narrow beam spread angle of ±15° according to the Ir-DA standard.  
      In this regard, a structure of an infrared communication module (infrared communication element) whose beam spread angle can be widened up to ±60° is proposed in general, as disclosed in Japanese Patent Laying-Open No. 11-288336 (1999), for example.  
      In the infrared communication module (infrared communication element) proposed in the aforementioned Japanese Patent Laying-Open No. 11-288336, a small mirror portion rotatable about X- and Y-axes serving as rotation centers is provided in front of a light-emitting diode and a photosensor, for allowing communication in the range of a cone having an apical angle of ±60° by rotating the small mirror portion by ±30° about the X- and Y-axes serving as rotation centers respectively.  
      According to the structure of the conventional infrared communication module disclosed in the aforementioned Japanese Patent Laying-Open No. 11-288336, however, no infrared communication is performable out of the range of the cone having the apical angle of ±60° serving as the beam spread angle although infrared communication is possible in the range of the cone having the apical angle of ±60° serving as the beam spread angle.  
     SUMMARY OF THE INVENTION  
      The present invention has been proposed in order to solve the aforementioned problems, and an object of the present invention is to provide an image generating apparatus capable of infrared communication over a wide range regardless of a beam spread angle of an infrared communication element.  
      An image generating apparatus according to a first aspect of the present invention comprises a rotating member horizontally rotatably set on the upper surface of an apparatus body performing printing and an infrared communication portion mounted on the rotating member for infrared communication of image data.  
      As hereinabove described, the image generating apparatus according to the first aspect of the present invention so comprises the rotating member horizontally rotatably set on the upper surface of the apparatus body performing printing and the infrared communication portion mounted on the rotating member for infrared communication of image data that the infrared communication portion of the apparatus body can be rotated to a position opposite to an apparatus transmitting an infrared signal corresponding to the image data by horizontally rotating the infrared communication portion of the apparatus body on the upper surface of the apparatus body along with the rotating member when the position of the apparatus transmitting the infrared signal corresponding to the image data horizontally deviates from the infrared communication portion of the apparatus body. Thus, the image generating apparatus, capable of receiving the infrared signal from the apparatus transmitting the infrared signal corresponding to the image data also when the position of the apparatus transmitting the infrared signal corresponding to the image data horizontally deviates from the infrared communication portion of the apparatus body, can perform communication of the image data between the same and the apparatus transmitting the infrared signal corresponding to the image data. Consequently, the image generating apparatus can perform infrared communication over a wide range regardless of the beam spread angle of the infrared communication portion of the apparatus body.  
      In the aforementioned image generating apparatus according to the first aspect, the apparatus body preferably includes a recess portion provided on an upper portion of the apparatus body circularly in plan view, the rotating member preferably includes a cylindrical portion having a circular shape substantially identical in size to the recess portion of the apparatus body in plan view, and the recess portion of the apparatus body preferably stores the cylindrical portion of the rotating member. According to this structure, the image generating apparatus, capable of rotating the rotating member while bringing the cylindrical portion thereof into surface contact with the recess portion of the apparatus body, can suppress backlash when horizontally rotating the rotating member on the apparatus body.  
      In the aforementioned image generating apparatus according to the first aspect, the infrared communication portion is preferably vertically rotatably mounted on the rotating member. According to this structure, the image generating apparatus can rotate the infrared communication portion of the apparatus body to the position opposite to the apparatus transmitting the infrared signal corresponding to the image data by vertically rotating the infrared communication portion of the apparatus body when the position of the apparatus transmitting the infrared signal corresponding to the image data vertically deviates from the infrared communication portion of the apparatus body. Thus, the image generating apparatus, capable of receiving the infrared signal from the apparatus transmitting the infrared signal corresponding to the image data also when the position of the apparatus transmitting the infrared signal corresponding to the image data vertically deviates from the infrared communication portion of the apparatus body, can perform communication of the image data between the same and the apparatus transmitting the infrared signal corresponding to the image data. Consequently, the image generating apparatus can perform infrared communication over a wider range regardless of the beam spread angle of the infrared communication portion of the apparatus body.  
      In this case, the rotating member preferably further includes an infrared communication portion mounting portion mounted with the infrared communication portion in addition to the cylindrical portion, and the infrared communication portion mounting portion is preferably inclined at a prescribed angle with respect to the extensional direction of the cylindrical portion of the rotating member. According to this structure, the image generating apparatus can move the infrared communication portion of the apparatus body to the position opposite to the apparatus transmitting the infrared signal corresponding to the image data by rotating the infrared communication portion of the apparatus body toward the uppermost side also when the apparatus transmitting the infrared signal corresponding to the image data is located immediately above the apparatus body. Thus, the infrared communication portion of the apparatus body can receive the infrared signal from the apparatus, located immediately above the apparatus body, transmitting the infrared signal corresponding to the image data, whereby the image generating apparatus can perform infrared communication over a wider range.  
      In the aforementioned structure having the infrared communication portion vertically rotatably mounted on the rotating member, the infrared communication portion preferably includes a rotating portion vertically rotatably mounted on the rotating member and an infrared communication element mounted on the rotating portion. According to this structure, the image generating apparatus can easily vertically move the infrared communication portion by vertically rotating the rotating portion.  
      In this case, the rotating portion of the infrared communication portion is preferably in the form of a column. According to this structure, the image generating apparatus can easily rotate the rotating portion mounted with the infrared communication element in the infrared communication portion mounting portion.  
      In the aforementioned structure having the infrared communication portion including the rotating portion and the infrared communication element, the rotating portion is preferably provided on the surface thereof with a corrugated grip portion touched by an operator for digitally rotating the rotating portion. According to this structure, the operator can easily vertically move the infrared communication portion by digitally rotating the corrugated grip portion.  
      In this case, the grip portion is preferably provided in the vicinity of each side end surface of the rotating portion. According to this structure, the operator can easily vertically move the infrared communication portion by digitally touching the grip portion closer to him/her.  
      In the aforementioned image generating apparatus according to the first aspect, the infrared communication portion of the apparatus body is preferably capable of receiving an infrared signal corresponding to image data from an apparatus having a camera function and an infrared communication function of transmitting the infrared signal corresponding to the image data picked up through the camera function. According to this structure, the image generating apparatus can easily fetch the infrared signal corresponding to the image data picked up through the camera function of the apparatus into the apparatus body through the infrared communication portion thereof.  
      In the aforementioned image generating apparatus according to the first aspect, the infrared communication portion of the apparatus body is preferably so formed as to perform infrared communication employing the Ir-DA standard having a prescribed beam spread angle. Also when employing the Ir-DA standard with an extremely small beam spread angle of ±15°, for example, the image generating apparatus according to the present invention can perform infrared communication over a wide range regardless of the beam spread angle.  
      An image generating apparatus according to a second aspect of the present invention comprises an infrared communication portion set on an apparatus body performing printing for infrared communication of image data and a rotating member horizontally rotatably set on the upper surface of the apparatus body performing printing, while the infrared communication portion of the apparatus body includes a rotating portion vertically rotatably mounted on the rotating member and an infrared communication element mounted on the rotating portion and is capable of receiving an infrared signal corresponding to image data from an apparatus having a camera function and an infrared communication function of transmitting the infrared signal corresponding to the image data picked up through the camera function, and the rotating portion is provided on the surface thereof with a corrugated grip portion touched by an operator for digitally rotating the rotating portion.

Thus, the image generating apparatus, capable of receiving the infrared signal from the apparatus transmitting the infrared signal corresponding to the image data also when the position of the apparatus transmitting the infrared signal corresponding to the image data horizontally deviates from the infrared communication portion of the apparatus body, can perform communication of the image data between the same and the apparatus transmitting the infrared signal corresponding to the image data. Consequently, the image generating apparatus can perform infrared communication over a wide range regardless of the beam spread angle of the infrared communication portion of the apparatus body. Further, the infrared communication portion is so vertically rotatably mounted on the rotating member that the image generating apparatus can rotate the infrared communication portion of the apparatus body to the position opposite to the apparatus transmitting the infrared signal corresponding to the image data by vertically rotating the infrared communication portion of the apparatus body when the position of the apparatus transmitting the infrared signal corresponding to the image data vertically deviates from the infrared communication portion of the apparatus body. Thus, the image generating apparatus, capable of receiving the infrared signal from the apparatus transmitting the infrared signal corresponding to the image data also when the position of the apparatus transmitting the infrared signal corresponding to the image data vertically deviates from the infrared communication portion of the apparatus body, can perform communication of the image data between the same and the apparatus transmitting the infrared signal corresponding to the image data. Consequently, the image generating apparatus can perform infrared communication over a wider range regardless of the beam spread angle of the infrared communication portion of the apparatus body.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      An embodiment of the present invention is now described with reference to the drawings.  
      The structure of a thermal transfer printer according to the embodiment of the present invention is described with reference to FIGS.  1  to  7 . According to this embodiment, the present invention is applied to the thermal transfer printer, which is an exemplary image generating apparatus.  
      As shown in FIGS.  1  to  6 , the thermal transfer printer according to this embodiment comprises a printer body  1 , a paper feed tray  2  detachably mounted on the printer body  1 , a rotating member  3  and an infrared communication portion  4  for communication of image data through an infrared signal.  
      According to this embodiment, the printer body  1  includes a receiving hole la for receiving an ink sheet cartridge (not shown) and a recess portion  1   b  rotatably holding the rotating member  3 , as shown in FIGS.  2  to  4 . The recess portion  1   b  of the printer body  1  is formed on the upper surface  1   c  of the printer body  1  circularly in plan view. The rotating member  3  is mounted on the printer body  1  to be rotatable by 360° along arrow A, as shown in  FIGS. 1 and 3  to  6 . This rotating member  3  includes a cylindrical portion  3   b  stored in the recess portion  1   b  of the printer body  1  and an infrared communication portion mounting portion  3   b  exposed outward. The cylindrical portion  3   a  of the rotating member  3 , having a cylindrical form substantially identical in size to the recess portion  1   b  of the printer body  1  in plan view, is inserted into the recess portion  1   b  of the printer body  1 . Thus, the printer body  1  holds the rotating member  3  in a state rotatable by 360° along arrow A. The infrared communication portion mounting portion  3   b  of the rotating member  3  provided in addition to the cylindrical portion  3   a  is inclined at a prescribed angle with respect to the extensional direction of the cylindrical portion  3   a . This infrared communication portion mounting portion  3   b  of the rotating member  3  is provided with an opening  3   c  for arranging the infrared communication portion  4  therein. A pair of rib portions  3   e  (see  FIG. 2 ) having engaging holes  3   d  (see  FIG. 2 ) rotatably holding the infrared communication portion  4  are provided in the vicinity of both longitudinal side surfaces of the opening  3   c  of the rotating member  3 , to inwardly project into the rotating member  3 .  
      According to this embodiment, the infrared communication portion  4  is mounted on the rotating member  3  to be vertically rotatable (along arrow B), as shown in  FIGS. 1 and 3  to  6 . This infrared communication portion  4  includes a rotating portion  4   a  in the form of a column and an infrared communication element  4   b , as shown in  FIG. 7 . The rotating portion  4   a  of the infrared communication portion  4  includes a pair of shaft portions  4   c  outwardly projecting along the extensional direction (along arrow C) of the rotating portion  4   a  respectively. The pair of shaft portions  4   c  of the infrared communication portion  4  are rotatably inserted into the engaging holes  3   d  of the rotating member  3  respectively. Thus, the infrared communication portion  4  is mounted on the rotating member  3  to be vertically rotatable (along arrow B) about the shaft portions  4   c . Grip portions  4   d  each having a plurality of projecting portions are provided in the vicinity of both side end surfaces of the rotating portion  4   a  of the infrared communicating portion  4  respectively at a prescribed interval along the direction of rotation of the infrared communication portion  4 .  
      As shown in  FIG. 1 , the infrared communication element  4   b  is so formed as to receive an infrared signal corresponding to image data transmitted from a portable telephone  10 , for example, through infrared communication. The portable telephone  10  is an example of the “apparatus” in the present Invention. This portable telephone  10  has a camera portion  10   a  capable of picking up images and an infrared communication element  10   b  for transmitting the infrared signal corresponding to data of the images picked up with the camera portion  10   a  to the thermal transfer printer, as shown in  FIG. 1 . The camera portion  10   a  is an example of the “camera function” in the present invention, and the infrared communication element  10   b  is an example of the “infrared communication function” in the present invention. The infrared communication elements  4   b  and  10   b  of the printer body  1  an d the portable telephone  10  correspond to the aforementioned Ir-DA standard. As shown in  FIG. 7 , the infrared communication element  4   b  is stored in the rotating portion  4   a  of the infrared communication portion  4 , to expose a communication surface outward. The communicable beam spread angles of the infrared communication elements  4   b  and  10   b  of the printer body  1  and the portable telephone  10  are ±15° in the vertical and horizontal directions. The infrared communication element  4   b  of the thermal transfer printer can receive the infrared signal corresponding to the image data transmitted from the portable telephone  10  through infrared communication, as shown in  FIG. 1 .  
      Operations of transmitting/receiving data between the thermal transfer printer according to this embodiment and the portable telephone  10  are now described with reference to FIGS.  8  to  11 .  
      According to this embodiment, the infrared communication element  4   b  of the printer body  1  may not receive the infrared signal transmitted from the infrared communication element  10   b  of the portable telephone  10  if the position of the portable telephone  10  horizontally deviates from the infrared communication portion  4  of the printer body  1 , since the beam spread angle for receiving the infrared signal introduced into the infrared communication portion  4  of the printer body  1  is ±15°. In this case, therefore, the infrared communication element  4   b  of the printer body  1  is rotated to a position opposite to the portable telephone  10  by rotating the infrared communication portion  4  of the printer body  1  along arrow A on the upper surface  1   c  of the printer body  1  along with the rotating member  3 , as shown in  FIGS. 8 and 9 . When the position of the portable telephone  10  horizontally deviates from the infrared communication portion  4  of the printer body  1 , therefore, the infrared communication element  4   b  of the printer body  1  is moved to the position for receiving the infrared signal transmitted from the infrared communication element lob of the portable telephone  10  so that the infrared communication portion  4  of the printer body  1  receives the infrared signal transmitted from the infrared communication element lob of the portable telephone  10 .  
      According to this embodiment, further, the infrared communication element  4   b  of the printer body  1  may not receive the infrared signal transmitted from the infrared communication element lob of the portable telephone  10  if the position of the portable telephone  10  vertically deviates from the infrared communication portion  4  of the printer body  1 , since the beam spread angle for receiving the infrared signal introduced into the infrared communication portion  4  of the printer body  1  is ±15°. In this case, therefore, the infrared communication element  4   b  of the printer body  1  is rotated to another position opposite to the portable telephone  10  by rotating the infrared communication portion  4  of the printer body  1  in the vertical direction (along arrow B), as shown in  FIGS. 10 and 11 . When the position of the portable telephone  10  vertically deviates from the infrared communication portion  4  of the printer body  1 , therefore, the infrared communication element  4   b  of the printer body  1  is moved to the position for receiving the infrared signal transmitted from the infrared communication element lob of the portable telephone  10  so that the infrared communication portion  4  of the printer body  1  receives the infrared signal transmitted from the infrared communication element  10   b  of the portable telephone  10 .  
      According to this embodiment, the beam spread direction of an infrared signal transmitted from the infrared communication element  4   b  of the printer body  1  is changed by rotating the rotating member  3  while rotating the infrared communication portion  4 . Thus, the range of the infrared communication element  10   b  of the portable telephone  10  for receiving the infrared signal is widely changed.  
      According to this embodiment, as hereinabove described, the thermal transfer printer so comprises the rotating member  3  set on the upper surface  1   c  of the printer body  1  performing printing to be rotatable along arrow A and the infrared communication portion  4  mounted on the rotating member  3  for infrared communication of image data that the infrared communication portion  4  of the printer body  1  can be rotated to the position opposite to the portable telephone  10  by rotating the infrared communication portion  4  of the printer body  1  on the upper surface  1   c  of the printer body  1  along arrow A along with the rotating member  3  if the position of the portable telephone  10  horizontally deviates from the infrared communication portion  4  of the printer body  1 . Thus, the infrared communication portion  4  of the printer body  1  can receive the infrared signal transmitted from the infrared communication element  10   b  of the portable telephone  10  also when the position of the portable telephone  10  horizontally deviates from the infrared communication portion  4  of the printer body  1 , whereby the thermal transfer printer can perform communication of image data between the same and the portable telephone  10 . Consequently, the thermal transfer printer can perform infrared communication over a wide range regardless of the beam spread angle of the infrared communication portion  4  of the printer body  1 .  
      According to this embodiment, the printer body  1  includes the recess portion  1   b  provided on the upper portion of the printer body  1  circularly in plan view and the rotating member  3  includes the cylindrical portion  3   a  having a circular shape substantially identical in size to the recess portion  1   b  of the printer body  1  in plan view so that the recess portion  1   b  of the printer body  1  stores the cylindrical portion  3   a  of the rotating member  3 , whereby the thermal transfer printer, capable of rotating the rotating member  3  while bringing the cylindrical portion  3   a  thereof into surface contact with the recess portion  1   b  of the printer body  1 , can suppress backlash when horizontally rotating the rotating member  3  on the printer body  1 .  
      According to this embodiment, the infrared communication portion  4  is mounted on the rotating member  3  to be vertically rotatable (along arrow B) so that the thermal transfer printer can rotate the infrared communication portion  4  of the printer body  1  to the position opposite to the portable telephone  10  by vertically rotating the infrared communication portion  4  of the printer body  1  if the position of the portable telephone  10  vertically deviates from the infrared communication portion  4  of the printer body  1 . Thus, the infrared communication portion  4  of the printer body  1  can receive the infrared signal transmitted from the infrared communication element  10   b  of the portable telephone  10  also when the position of the portable telephone  10  vertically deviates from the infrared communication portion  4  of the printer body  1 , whereby the thermal transfer printer can perform communication of image data between the same and the portable telephone  10 . Consequently, the thermal transfer printer can perform infrared communication over a wider range regardless of the beam spread angle of the infrared communication portion  4  of the printer body  1 .
