Abstract

(57) [Abstract] [Purpose] It is an object to provide a card reader / writer having a structure in which a coin does not enter the far end of a card passage. [Structure] An inclined surface K, which is wider than the coin F and is lowered toward the insertion slot B, is formed on the lower surface J of the card passage D, so that it is inserted into the insertion slot B as shown in FIG. The coin F separated from is dropped on the inclined surface K formed on the lower surface J of the card passage D inside the insertion slot B as shown in (b), and is slid out of the card passage D and is naturally discharged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a card reader / writer used in a vending machine, a public telephone, and the like.

[0002]

[Prior art]

 A conventional card reader / writer for reading and writing information from a card inserted by a user is configured as shown in FIGS. 3 and 4.

An outside guide surface C is formed outside the insertion slot B into which the card A is inserted by the user, and the card A guided to the insertion slot B by this guide surface C is shown in FIG. As shown, it is pushed all the way into the card passage D. Reference numeral E is an input / output electrode, which comes into contact with the contact electrode of the card A pushed to the innermost end of the card passage D.

[0004]

[Problems to be solved by the device]

 With such a configuration, when the user mistakenly inserts the coin F into the insertion slot B as shown in FIG. If the card A is inserted into the insertion slot B without noticing the inserted coin F as shown in b), the input / output electrode E comes into contact with the coin F and is electrically short-circuited, causing damage to the electrical component board. To do.

An object of the present invention is to provide a card reader / writer having a structure in which the coin F does not enter the deep end of the card passage D.

[0006]

[Means for Solving the Problems]

 The card reader / writer according to claim 1 is a card reader / writer for reading / writing information from / into a card inserted into an inner end of the card passage through an insertion slot, wherein the card reader / writer is wider than the coin on the lower surface of the card passage. And a slanted surface that is lowered toward the insertion port is formed.

The card reader / writer according to claim 2 is a card reader / writer for reading / writing information from / to a card inserted into the inner end of the card passage through the insertion port, wherein the outside of the insertion port is: A guide surface is formed that expands to guide the card to the insertion slot, and an inclined surface that is wider than the coin and becomes lower toward the insertion slot is formed on the lower surface of the card passage inside the insertion slot. And

[0008]

[Action]

 According to the structure of each claim, the card wider than the coin enters the card passage from the insertion slot and reaches the inner end of the card passage. The coin inserted into the insertion slot and separated from the user's hand falls on the inclined surface formed on the lower surface of the card passage inside the insertion slot, and slides out of the card passage.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. It should be noted that components having the same functions as those of the conventional example shown in FIGS.

FIG. 1 shows a card reader / writer of the present invention. On both sides of the insertion slot B and on the outer side G of the insertion slot B, there are formed guide surfaces Ca and Cb for expanding the card A to the insertion slot B. On a part of the lower surface J of the card passage D inside the insertion slot B, an inclined surface K that is wider than the diameter of the coin F and narrower than the card width and is lowered toward the insertion slot B is formed. Has been done.

With this configuration, when the coin F is mistakenly inserted into the card passage D from the insertion opening B as shown in FIG. 2A, the coin F separated from the user's hand is inclined. It falls on the surface K, slides down on the inclined surface K as shown in FIG. 2B, and is naturally discharged to the outside of the card passage.

In the case of the card A, the inserted card A engages with the non-inclined card passages D on both sides of the inclined surface K and is reliably pushed into the deep end of the card passage D. Therefore, it is possible to avoid the occurrence of an accident in which the coin F enters the deep end of the card passage D, and it is possible to prevent the read / write failure of the card A.

In the above embodiment, the inclined surface K is formed only in the central portion of the card passage D. However, due to the difference in the length of the card A and the diameter of the coin F, the insertion opening B is formed on the lower surface of the card passage D. The same effect can be expected by forming the inclined surface K over the entire width.

The length of the inclined surface K in each of the above-described embodiments is the same even if the inclined surface K starts from the insertion opening B and extends further toward the back side of the card passage D as shown by the phantom line in FIG. 2B. The effect of can be expected.

[0015]

[Effect of device]

 As described above, according to the present invention, since the lower surface of the card passage is formed with the inclined surface which is wider than the coin and is lowered toward the insertion slot, the coin inserted into the insertion slot and separated from the user's hand is , It is possible to avoid the accident that the coin F falls to the inclined surface formed on the lower surface of the card passage inside the insertion slot, slides out of the card passage and is naturally ejected, and the coin F enters the deep end of the card passage D. can do.
