  The detection switch 9 includes a fixed switch piece 91 and a movable switch piece 92 driven by the metal engaging portion 73. When the rotary cover 7 is locked, the fixed switch piece 91 and the movable switch piece 92 Is configured so as to be short-circuited, so that it is possible not only to detect whether or not the IC card 20 is received in the IC card receiving recess 33 with a single switch mechanism, but also the IC card 20 is received in the IC card receiving recess 33. It is also possible to detect whether or not the rotary cover 7 is locked to the housing 3.

  Further, it is possible to prevent the detection switch 9 from malfunctioning due to a change (inversion) in the posture of the card connector. Further, even if the IC card 20 is accommodated in the IC card accommodation recess 33, the detection switch 9 is not closed when the rotary cover 7 is not locked to the housing 3. Therefore, by detecting the output of the detection switch 9, it is possible to prevent malfunction on the device side when the user erroneously locks the rotating cover 7 and the IC card 20 protrudes from the IC card housing recess 33. .

  Furthermore, a release detection signal is output when the locked state of the rotary cover 7 is released, and the IC card 20 and the print are printed until the contact state between the IC card 20 and the contacts 53 and 63 of the contacts 5 and 6 is released. The work being performed with the substrate (equipment) is terminated. Then, circuit protection can be realized. In this embodiment, by providing a restricting portion 321b that restricts the upward rotation of the metal engaging portion 73 when the metal engaging portion 73 is moved forward of the housing 3, the rotation cover 7 is locked. Between the start of the release operation and the actual contact state between the IC card 20 and the contacts 53 and 63 of the contacts 5 and 6, the two operations of the slide operation and the rotation operation of the rotary cover 7 are necessary. Since a certain amount of time can be secured, this time can be effectively used for circuit protection.

A part of the contact spring portion 292 b is accommodated in a recess 2323 a formed in the third frame component 2323. The remaining portion of the contact spring portion 292b is accommodated in an engagement portion space 2321a formed in the first frame constituent portion 2321 so as to be elastically deformable. The contact spring drive portion 292c is coupled to one end of the contact spring portion 292b. The contact spring portion 292b is always in contact with the contact point 291c of the fixed switch piece 291 when no external force is applied. The contact spring driving portion 292c is curved downward and is located below the contact point 291c of the fixed switch piece 291. Thus, the detection switch 209 is a normally closed type switch.

  The engaging portion 277 is formed at the distal end portion of one arm 272 of the rotary cover 207 and extends toward the housing 203. The engaging portion 277 does not need to have conductivity. As described in the first embodiment, when the engagement portion 277 is rotated to the closed position with the IC card receiving recess closed with respect to the housing 203, the engagement portion 277 enters the engagement space 2321a and is moved to the lock position.

  As shown in FIGS. 8A to 8C, when the IC card 20 is not accommodated in the housing 203, even if the rotary cover 207 is rotated to the closed position and moved to the locked position, the engaging portion 277 remains on the movable switch piece 292. The contact spring drive unit 292c is not driven. At this time, the contact 291 c of the fixed switch piece 291 does not leave the movable switch piece 292. As a result, the detection switch 209 remains closed, and it is detected that the IC card 20 is not accommodated in the housing 203.

  9A to 9C, when the IC card 20 is accommodated in the housing 203, when the rotary cover 207 is rotated to the closed position and moved to the lock position, the rotary cover 207 is contacted via the IC card 20 with the contact 5. It is lifted by the spring part 53. At this time, the engaging portion 277 of the rotary cover 207 lifts the contact spring driving portion 292c of the movable switch piece 292. As a result, the spring portion 292b of the movable switch piece 292 is separated from the contact 291c of the fixed switch piece. As a result, the detection switch 209 is opened to detect that the IC card 20 is received in the housing 203. The engaging portion 277 is engaged with a restricting portion 2321b provided in the first frame constituent portion 2321 when the rotary cover 207 is moved to the lock position, similarly to the metal engaging portion 73 of the first embodiment. To lock. Although not shown, an engaging portion similar to the engaging portion 277 is provided at the distal end portion of the other arm 272 of the rotation cover 207, and the restricting portion 2322 b of the second frame constituent portion 2322 is provided. Engage and lock.

  The second embodiment has the same effects as the first embodiment.

  Although the card connector of the first and second embodiments is for the IC card 20, the present invention can be applied to card-type electronic components other than the IC card.

  Further, in the above-described embodiment, the connection object storage portion is the IC card storage recess 33, but the shape of the connection object storage portion is not limited to the recess, and may be, for example, a hole or four corners of the connection object. It may be only for positioning.

  Various configurations of the detection switches 9 and 209 are conceivable and are not limited to those of the above-described embodiment.

  The number of detection switches 9 and 209 may be two or more. In this case, one of the detection switches can be used as a dedicated switch for detecting the locked state of the rotary covers 7 and 207.
