As shown in FIG. 16, the card read / write device 700 having the above-described configuration is used for an office desk or an OA equipment desk 1.
It is used by being placed on the 101 so as to stand upright. The insertion / removal direction of the IC card 900 with respect to the card reading / writing device 700 thus installed is
The direction of the card receiving gap 501 in the card reading / writing device 700 is 20 degrees (= θ) with respect to the vertical.
In the forward leaning direction. The inclination angle in the insertion / removal direction substantially matches the forward inclination posture of the upper case 200 rising from the base plate 100 with the card reading / writing unit 500 defining the card receiving gap 501 built-in, so that the user can easily understand the inclination angle.

For example, in FIG. 16, in the case of an IC card 900 inserted at an angle close to vertical, an IC card 900 is formed by a rear wall surface 226 inclined to open rearward and a front wall surface 223 curved convexly. Even if the leading end of the card 900 is shifted, the card receiving gap 5 is formed by the curved surface with the inclined surface.
01 can be guided.

Similarly, the left and right displacement of the IC card 900 can be guided by the side walls 224 and 225 on both sides inclined inward.

As described above, in this embodiment, the operation of inserting the IC card 900 can be remarkably facilitated.

Then, the inserted IC card 900 is
The auxiliary card holder 52 falls down to the near side in accordance with the forward leaning posture.
Since the posture is along the inner surface of 0, the distance to the antenna circuit board 530 located outside the surface is stabilized, and the electromagnetic coupling by the antenna coil is stabilized.

The corrugated surface 121 of the front half 120 extending toward the front side of the base plate 100 is used as a scaffold for placing the writing implement 1102 and making the IC card 900 horizontally long and leaning against the front side of the upper case 200. Can be.

Next, the standing angle of the upper case 200 and the card receiving gap 501 of the card reading / writing unit 500
(The forward tilt angle θ with respect to the vertical) will be described. As shown in FIG. 17, the card reading / writing device 700 is placed on an office desk 1101, and a user 1103 sits on a chair and inserts and removes the IC card 900 while standing. There is a usage form in which the insertion / removal operation is performed in a posture. The placement position also has a central area and a rear area on the desk. The rear region is a limit position at which the user 1103 sitting on the chair can reach the limit by reaching.

This will be described in more detail. The ordinary office desk 1101 is provided with a table surface with a depth of 80 cm at a position with a height of 70 cm. The height of each part of a standard physique operator who uses the office desk 1101 in a posture of sitting on a chair is as follows: elbow height is 62 cm, and eye level is 110 cm.
It is about 120 cm. In the standing posture, the elbow height is 98 cm to 108 cm, and the eye level is 145 cm to 15 cm.
It is about 5 cm. The use of the card reading / writing device 700 on such an office desk 1101 can be performed by a keyboard 1104 which is assumed to be frequently used by an operator having a standard physique.
Central area (65c from the operator's central axis)
m, a normal distance of 40 cm from the front end of the table surface).

First, the card reading / writing device 7 is set in a sitting posture.
When the operator operates 00, the operator lifts the elbow to a position slightly higher than the height of the table surface (70 cm), and inserts and removes the card in a posture looking down from a height of about 115 cm. With the wrist facing down. On the other hand, when operating in the standing posture, 150c
In a posture looking down from a height of about m, the card insertion / removal operation is performed with the hand holding the card extended and the wrist directed downward.

Generally, if the angle of the line of sight matches the forward inclination angle of the card receiving gap 501, the operator can properly insert the card, as shown in FIG. The forward tilt angle of the card receiving gap 501 that most closely matches the line of sight in the posture is an angle substantially matching the angle of sight of 45 degrees. In addition, the forward inclination angle of the card receiving gap 501 that most closely matches the line of sight in the standing posture is 30 degrees of the line of sight.
It is an angle that approximately matches the degree. As shown in FIG. 17, the angle of the line of sight increases when the card reader / writer 700 is installed in the front area of the table surface, and decreases when the card reader / writer is installed in the rear area. However, a display device is generally installed in the rear area, and the card read / write device 700 is often installed in front of the display screen of the display device. What is necessary is to consider the usage form.

The relationship between the line of sight and the card insertion / removal angle is as follows:
The range can be set wide depending on the shape of the card insertion / removal window 220. In this embodiment, since the card insertion / removal window 220 having the shape of the inverted flared dent is adopted, if the angle is around the line of sight, the line of sight angle and the forward inclination angle of the card receiving gap 501 match. The same operability can be obtained.

On the other hand, when the operability in the above posture is verified from the viewpoint of inserting / removing the card, in both the sitting posture and the standing posture, the card is inserted / removed with the wrist facing down. From this point of view, the operability of the card receiving gap 501 is improved when the card is inserted and removed in a standing posture. Further, in consideration of insertion / removal while checking the card insertion / removal window 220, the operation is easier when the insertion / removal angle is larger than the angle of the line of sight.

Therefore, in the present invention, the angle of the card receiving gap 501 is set to 45 degrees or more based on the angle of the line of sight of the operator in the sitting posture and the standing posture and the card insertion / removal angle. Further, in the present invention, since the card and the card reading / writing device 700 are connected in a non-contact manner, the card must be in close contact with the antenna circuit board 530 inserted in the card receiving gap 501.
