are included in images stored in the memory


500


as the image data. The index images, showing marks of the types (club, diamond, heart or spade) to which playing cards belong and ranks (ace, 2 to 10, jack, queen or king) of the playing cards or a joker, are generally printed on the upper left and the lower right of the surfaces of the playing cards.




The image signal of the object


70


from the camera


30


is received by an image correction device


53


, and the image correction device


53


corrects the image of the object


70


. This is because, when the camera


30


and the object


70


are in the arrangement shown in

FIG. 1

, the image of the object


70


photographed by the camera


30


has a trapezoidally distorted shape with a large head portion and small leg portions. The image signal of the object


70


corrected by the image correction device


53


is transmitted to the image synthesis device


54


.




The image synthesis device


54


receives the image signal of the object


70


as a first image signal, receives the image signal of the storage image from the graphic I/F circuit


51


as a second image signal, and synthesizes the first image and the second image. A method of synthesizing the images is described in Japanese Utility Model Registration No. 3043855, Japanese Utility Model Registration No. 3051776 or the like in detail, and hence detailed description thereof is omitted here. The image synthesis device


54


has a plurality of synthesis methods, and it is preferable to select a single synthesis method by an instruction from the PC


50


. The synthesized image signal is transmitted to the display selection circuit


55


and the printer


65


.




The display selection circuit


55


receives the synthetic image signal from the image synthesis device


54


and the storage image signal from the graphic I/F circuit


51


, selects either image signal on the basis of a control signal from the PC


50


and transmits the same to the display


60


. The display


60


receives the image signal from the display selection circuit


55


and displays the image.




The control part


5


includes a printer controller


56


controlling the printer


65


on the basis of a control signal from the PC


50


. The printer


65


receives the synthetic image signal from the image synthesis device


54


, stores the data of the synthetic image in a memory


650


built in the printer


65


, forms a print image on the basis of the synthetic image data and prints the print image on the card base


67


of a prescribed size under control by the printer controller


56


.




Data is directly transferred from the PC


50


to the printer


65


so that printing on the back of the card is performed. The data is present in the memory


500


.




The control part


5


includes various types of counters


58


counting/displaying the number of inserted coins and the like.




Operations of the card vending machine


1


having the aforementioned structure are now described.




Until the user


7


inserts a coin, the display selection circuit


55


selects the graphic I/F circuit


51


side by an instruction from the PC


50


. The PC


50


reads the data of the demo image previously stored in the memory


500


and transfers the same to the graphic I/F circuit


51


, whereby a demo screen is displayed on the display


60


. The PC


50


reads BGM (background music) data previously stored in the memory


500


and transfers the same to the sound I/F circuit


52


, whereby background music is played through the speaker


63


.




When the user


7


inserts a coin and the PC


50


receives the detection signal from the coin detection part


25


, the PC


50


reads the image data and the sound data previously stored in the memory


500


at proper timing and transmits the read image data to the display


60


through the graphic I/F circuit


51


and the display selection circuit


55


while transmitting the read sound data to the speaker


63


through the sound I/F circuit


52


for properly supplying an instruction to the user


7


with the image on the display


60


and the sound from the speaker


63


and performing operations shown in FIG.


3


.




Referring to

FIG. 3

, it first successively reads a plurality of storage image data stored in the memory


500


and makes the display


60


display the same through the graphic I/F circuit


51


and the display selection circuit


55


, and makes the user


7


operate the operating part


20


and select a desired storage image (S


10


).

FIG. 4

shows a flow chart illustrating this routine in detail.




Referring to

FIG. 4

, it first makes the display


60


display a plurality of back images and makes the user


7


select a desired back image (S


101


).




Then, it makes the user


7


select an index image. More specifically, it makes the display


60


display the marks of the types to which the cards belong and the mark of the joker, and makes the user


7


select a desired mark (S


102


).




Then, it determines whether or not the user selects the mark of the joker (S


103


), for making the display


60


display images indicating the ranks of the cards and making the user


7


select a desired image (S


104


) when not selecting the joker, while advancing to a next step when selecting the joker.




Thus, the type and the rank of the card the user


7


desires or a supply joker is selected.




Then, it makes the display


60


display the plurality of decorative images and makes the user


7


select a desired decorative image (S


105


). At this time, the PC


50


may select a decorative image at random in place of the user


7


selecting the decorative image.




Then, it makes the user


7


select a method of synthesizing the images S


106


). Then, the PC


50


synthesizes the selected index image and decorative image by the selected synthesis method, and makes the display


60


display the synthesized storage image (S


107


).




Then, it makes the user


7


determine whether or not to utilize the synthetic storage image displayed on the display


60


(S


108


), for returning to the step S


101


when making selection again without utilizing it while returning to the original routine and continuously transferring the data of the synthetic storage image to the graphic I/F circuit


51


when utilizing it.




As the structure of the object image synthesized into the synthetic storage image, an image of the whole body or an image of the upper half of the body, a single image or a plurality of images, a one-shot image or plural-shot images can be exemplified. After selecting the desired storage image (S


10


), therefore, the user selects one from the aforementioned image structures of the object


70


(S


11


).




Then, the PC


50


instructs the image synthesis device


54


to convert the image of the object


70


to the selected image structure and thereafter synthesize the converted image of the object


70


and the synthesized storage image in real time while switching the display selection circuit


55


to the image synthesis device


54


side and making the display


60


display the synthetic image from the image synthesis device


54


in real time (S


12


).




Then, when the user


7


presses an adjustment end button of the operating part


20


after completing position adjustment of the object


70


while observing the display image on the display


60


(S


13


), the PC


509


instructs the user


7


to pose and then instructs the image synthesis device


54


to stop image synthesis (S


14


). At this time, the synthetic image immediately before stoppage is displayed on the display


60


as a static image.




Then, the user


7


determines whether or not to print the said still image (S


15


) for pressing a retake button of the operating part


20


when making a retake without printing while pressing a print button of the operating part


20


when performing printing. When the retake button is pressed, the PC


50


returns to the step S


81


and repeats the aforementioned operations.




When the print button is pressed, the PC


50


transmits an instruction signal to the printer controller


56


to make the printer


65


print the said still image on the surface of the card base


67


and print the selected back image on the back, and provides the printed card base


67


to the user


7


(S


16


).




Until another coin is inserted, it plays background music and displays the demo image similarly to the aforementioned case before coin insertion.




When this embodiment is structured and operates as described above, the memory


500


in the PC


50


stores the game image and the decorative image as digital data and hence it is easy to synthesize the game image and the decorative image. The synthesized image is immediately printed in the printer


65


, and hence a card provided with various colors or patterns can be produced at a low cost and in a short time by selection of the user


7


.




Further, the card vending machine


1


according to this embodiment synthesizes the image of the object


70


photographed with the camera


30


on the image obtained by synthesizing the game image and the decorative image in the PC


50


with the image synthesis device


54


and prints the same with the printer


65


, and hence it follows that the degree of freedom of images selectable by the user


7


widens.




Specific examples of the actually printed card are now described.





FIG. 5

is a diagram showing a first specific example of the surface of the printed card.




Referring to the figure, game images


100




a


to


100




d


necessary for a game, decorative images


200




a


to


200




g


not directly related to the game and object images (personal images here)


300


are synthesized on the card.




Images of the whole bodies of persons are printed as the object images here.





FIG. 6

is a diagram showing a second specific example of the surface of the printed card.




Referring to the figure, game images


100




a


to


100




d


necessary for a game, a decorative image


200


not directly related to the game and object images


300




a


and


300




b


are synthesized on the card.




Images of the upper half of the body of the same person are printed to be vertically symmetrical as the object images here.





FIG. 7

is a diagram showing a third specific example of the surface of the printed card.




Referring to the figure, game images


100




a


to


100




d


necessary for a game, a decorative image


200


not directly related to the game and an object image


300


are synthesized on the card.




The facial part of a person is printed as the object image here.





FIG. 8

is a diagram showing a fourth specific example of the surface of the printed card.




Referring to the figure, game images


100




a


to


100




d


necessary for a game and object images


300


are synthesized on the card.




The user can purchase the cards shown in

FIG. 5

to

FIG. 8

by self selection.




FIG.


9


and

FIG. 10

are diagrams showing specific examples of the back image of the card.




Referring to the figures, images of labyrinths are included in the back images to appear to be patterns to the human eyes at a glance. While FIG.


9


and

FIG. 10

are labyrinthine images different from each other, the same appear to be the same patterns to the human eyes at a glance.




When printing an image of a labyrinth on the back of the card in this manner, variations of the game with the card widen. Also when printing different labyrinthine images on the respective ones of cards included in a pack of cards, they give the impression as if they are the same patterns to the human eyes at a glance, and hence they do not hinder the essential game object of the playing cards.




While the printer


65


of this embodiment prints the images on both surfaces of the card base, a plurality of card bases


67


on which back images are previously printed may be prepared for selecting a card base


67


on which a back image selected by the user


7


is printed from the card bases


67


and printing a still image on the surface of the selected card base


67


.




While this embodiment vends a single card used for a card-type plaything, it is also possible to vend cards (if playing cards,


54


cards including two jokers) of a number necessary for playing a game.




Further, a magnetic recording part capable of rewriting information may be previously arranged on the card base


67


and a function of a magnetic writer writing information in the magnetic recording part may be added to the printer


65


printing the image.




Another storage part such as an IC can be arranged on the card base in place of a magnetic body. In this case, it follows that a function of writing information in the storage part is added to the printer


65


. In addition, a write part writing information in the storage part


65


′ can be arranged on the card vending machine


1


independently of the printer


65


.




When thus providing a storage part on the card, writing a message, a date, a cipher and the like in the storage part, reading the written contents with another device (or the card vending machine performing writing) and making display (or printing), it is possible to increase the number of variations of the game with the card.




While this embodiment synthesizes and prints the image of the object


70


photographed with the camera


30


, the effect of the present invention can be attained also when synthesizing and printing the game image and the decorative image selected by the user


7


without synthesizing the object image. In this case, the camera


30


, the image correction device


53


and the image synthesis device


54


are unnecessary.




Further, Japanese playing cards, cards of the Hundred Poems by One Hundred Poets and other cards for games may be vended as cards.




While the above embodiment has been described with reference to a card vending machine, the present invention is also applicable to a card manufacturing machine simply manufacturing cards with no payment of the price.




Further, the present invention is applicable also to a device printing an image (image responsive to the taste of the user) that the user obtains by selection, entry, drawing or photographing on a card.




The printer


65


may perform printing on the card base


67


for obtaining a single card


67




a


as shown in

FIG. 11

, or a printer


65




a


performing printing on a card base
