  FIG. 1 shows an embodiment of the present invention and shows the configuration of an image print system.

  The image print system includes an image data receiving device 4 and a print accepting device 8. The image data receiving device 4 and the print accepting device 8 are arranged in the convenience store 1. However, it goes without saying that the image data receiving device 4 and the print receiving device 8 are not limited to the convenience store 1. The image data receiving device 4 is arranged near the entrance 3 of the convenience store 1.

  The image data receiving device 4 transmits (transmits) an activation signal (a beacon may be used) to an area Ar within a predetermined range. If the area Ar is within a predetermined range centering on the image data receiving device 4, the activation signal transmitted from the image data receiving device 4 can be received. Further, the image data receiving device 4 can receive image data to be transmitted and transmit the received image data to the print acceptance device 8.

  In this embodiment, a user 2 having a portable image terminal 10 prints an image represented by image data stored in the portable image terminal 10 using a print acceptance device 8. . When the user 2 having the portable image terminal 10 enters the area Ar, the advance activation signal transmitted from the image data receiving device 4 is received by the portable image terminal 10. Then, activation and pre-processing of circuits and the like that take time for activation and processing among the circuits and the like built in the portable image terminal 10 are started. When the user 2 goes to the image data receiving device 4, the user 2 transmits image data representing an image to be printed from the portable image terminal 10 to the image data receiving device 4. Before the user 2 goes to the image data receiving device 4, the start-up and pre-processing of the circuit and the like that take time are completed. When the user 2 arrives at the image data receiving device 4, the user 2 can immediately transmit the image data from the portable image terminal 10 to the image data receiving device 4.

  The image data receiving device 4 that has received the image data transmits the received image data to the print acceptance device 8. When the user 2 enters the convenience store 1 and arrives at the print receiving device 8, printing in the print receiving device 8 has been completed, and the user can immediately receive the print. Needless to say, the image to be printed, the number of prints, etc. are preset.

  FIG. 2 shows the appearance of the portable image terminal 10 and the image data receiving device 4.

  The portable image terminal 10 incorporates an activation signal receiving circuit 12, and a laser emission surface 11A for outputting a laser representing image data is formed on the front surface.

  The image data receiving device 4 has a built-in start signal transmitting circuit 6 for transmitting a start signal, and a receiving sensor 5 for receiving a laser output from the portable image terminal 10 is provided on the upper surface.

  As described above, the activation signal is transmitted from the image data receiving device 4, and the activation signal can be received from the image data receiving device 4 in the area Ar within a certain range. The portable image terminal 10 that has received the activation signal performs necessary circuit activation and pre-processing as described above.

  FIG. 3 is a block diagram showing an electrical configuration of the portable image terminal 10.

  The portable image terminal 10 includes a mode designation / selection switch 13 that can set modes such as a pre-start mode, an imaging mode, and a reproduction mode. The portable image terminal 10 can take an image of a subject, and for this purpose, a CCD 15 is included. Image data picked up by the CCD 15 is subjected to predetermined signal processing in the signal processing circuit 14 and recorded in the memory card 24 under the control of the memory card control circuit 25.

  The portable image terminal 10 includes a laser device 11. The laser device 11 outputs (transmits) a laser representing image data. The output of the laser device 11 is controlled by an output / modulation control circuit 16.

  The direction of the emitted light of the laser output from the laser device 11 is adjusted by the gimbal mirror 18 so that the laser output from the portable image terminal 10 does not blur. The mirror 18 having this gimbal structure is one in which the mirror control circuit 17 adjusts the reflection angle of the mirror. The portable image terminal 10 uses the angular velocity to detect the blur angle by integrating the angular velocity sensor 19 (blur direction detection sensor) for detecting the blur direction and the value obtained by the angular velocity sensor 19 to detect the blur angle. An integration / blur amount detection circuit 20 (blur amount detection sensor) for detecting the amount of blur is included. Data representing the angular velocity detected by the angular velocity sensor 19 is supplied to the integration / blur amount detection circuit 20, and the blur direction and the blur amount of the portable image terminal 10 are detected. Needless to say, other known blur direction sensors and blur amount detection sensors may be used. As described above, the reflection angle of the mirror 18 is controlled by the mirror control circuit 17 so as to correct the shake based on the detected shake direction and shake amount (blur correction device).

  The portable image terminal 10 also includes a selection switch 22 for selecting transmission data (image data to be printed) and buttons 23 including buttons for giving an image data transmission start command to the portable image terminal 10. The portable image terminal 10 also includes a RAM 26 that temporarily stores data. Further, the portable image terminal 10 also includes a data format forming circuit 27 for forming a data format suitable for laser output from the laser device 11.

  The time taken to read image data from the RAM 26 is faster than the time taken to read image data from the memory card 24. For this reason, in this embodiment, when an activation signal is received, the image data recorded in the memory card 24 is read out and written in the RAM 26. The image data written in the RAM 26 is read out and laser output is performed.

  Further, the portable image terminal 10 receives the activation signal as described above, so that the advance activation control circuit 28 for controlling a circuit for performing activation and preprocessing, etc., for controlling communication of image data A main communication control circuit 29, a display device 30, a start signal receiving circuit 12, and a start signal receiving antenna 31 are included.

  4 and 5 are flowcharts showing processing procedures of the portable image terminal 10, and FIG. 6 is a flowchart showing processing procedures of the image data receiving device 4 and the print receiving device 8. As shown in FIG.

  As described above, when the user 2 approaches the image data receiving device 4 while holding the portable image terminal 10, the portable image terminal 10 is set to the pre-start mode by the user 2 (step 41 in FIG. 4). . Then, the activation signal receiving circuit 12 is activated (step 42 in FIG. 4). As a result, the activation signal transmitted from the image data receiving device 4 can be received. Of course, it goes without saying that the processing described later may be performed regardless of whether the pre-start mode is set.

  An activation signal is transmitted from the image data receiving device 4 (step 61 in FIG. 6). As described above, when the user 2 with the portable image terminal 10 enters the area Ar that can receive the activation signal, the activation signal is received by the portable image terminal 10 (step 43 in FIG. 4).

  If the activation signal is not received by the portable image terminal 10 (NO in step 43 in FIG. 4), it is confirmed whether the pre-activation mode is set (step 51 in FIG. 4). If the pre-start mode is set (YES in step 51 in FIG. 4), the process returns to step 43 again. If the pre-start mode is not set (NO in step 51 in FIG. 4), the process ends.

  When the activation signal is received by the portable image terminal 10 (YES in step 43 in FIG. 4), activation of the angular velocity sensor 19 and the integrating circuit 20 starts (step 44 in FIG. 4). When the angular velocity sensor 19 and the integrating circuit 20 are stabilized (YES in step 45 in FIG. 4), the completion of preparation is displayed on the display device 30 (step 48 in FIG. 4). Of course, both the angular velocity sensor 19 and the integrating circuit 20 may be activated without starting activation.

  When the activation signal is received by the portable image terminal 10 (YES in step 43 in FIG. 4), the image data to be printed is read from the memory card 24 and written in the RAM 26 (step 46 in FIG. 4). When the writing to the RAM 26 is completed, a message to the effect that preparation is complete is displayed on the display device 30 (step 48 in FIG. 4).

  After completion of preparation, it is confirmed whether or not an activation signal is received (step 49 in FIG. 4). If the activation signal has not been received (NO in step 49 in FIG. 4), the angular velocity sensor 19 and the integration circuit 20 are activated, the image data is read from the memory card 24, and the image data is written to the RAM 26 in advance. Is stopped (step 50 in FIG. 4).

  When the activation signal is received (YES in step 49 in FIG. 4), when the user 2 reaches the image data receiving device 4, the laser emission surface 11A of the portable image terminal 10 is moved to the image data receiving device 4. A portable image terminal 11 is placed on the upper surface of the image data receiving device 4 so as to face the receiving sensor 5. Thereafter, the transmission button included in the buttons 23 is pressed by the user 2 (step 52 in FIG. 5). Then, the image data written in the RAM 26 is read, and the laser is transmitted from the laser device 11 to the image data receiving device 4 (step 53 in FIG. 5). Since the reading speed of the image data from the RAM 26 is faster than the reading speed of the image data from the memory card 24, the laser can be transmitted quickly. Further, since the angular velocity sensor 19 and the integrating circuit 20 are also activated, the mirror 18 can be immediately controlled so as not to be shaken, and laser transmission from the laser device 11 can be performed quickly.

  The result of transmission from the portable image terminal device 10 to the image data receiving device 4 is displayed (step 54 in FIG. 5). For example, transmission results such as successful transmission, transmission failure, and unknown transmission destination will be displayed. Thereafter, each circuit of the portable image terminal device 10 is stopped (step 55 in FIG. 5).

  When the image data (laser) transmitted from the portable image terminal 10 is received by the image data receiving device 4 (YES in step 62 in FIG. 6), the received image data is transferred from the image data receiving device 4 to the print acceptance device 8. (Step 63 in FIG. 6).

  When the image data transmitted from the image data receiving device 4 is received by the print accepting device 8 (step 71 in FIG. 6), an image represented by the received image data is printed by the print accepting device 8 (FIG. 6). 6 Step 72).

  The user 2 walks from the image data receiving device 4 to the print receiving device 8. When the user arrives at the print receiving device 8, the image printing is finished.

  In the above-described embodiment, the image data written in the memory card 24 is read and written in the RAM 26 when the activation signal is received. However, the image data is converted into a format suitable for communication. You may make it leave. Further, although an image to be printed is selected in advance, an image represented by image data newly input to the portable image terminal 10 after transmission of the previous image data may be used as an image to be printed.
